What are the different characteristics of different drum structures of bucket elevators?

<> "Bucket elevator drum can be divided into two categories: power drum and non-power drum.

Among them, the power drum is divided into built-in motor and external motor, and the built-in motor has the advantages of compact structure, flexible installation and good sealing performance. But the production cost is high and the most expensive. The cost of the external motor is relatively pointed, and the energy consumption is more direct than that of the bottom of the unpowered drum and the power transmission, and the installation flexibility is inferior to that of the built-in motor drum.

According to the shape and structure of the non-powered drum, there are welded solid drums, cast solid drums, welded face drums, and cast face drums.

The solid drum is generally used as an active roller on the nose seat, which is conducive to increasing the friction with the bucket belt and reducing the vibration.

The flower surface drum is generally used as a driven drum under the tail seat, which can effectively reduce the material crushing rate and reduce the weight.

Different drum structures of bucket elevators have different characteristics. The difference between the two drum structures of the hoist is that the spoke plate of the former is perpendicular to the axis, while the support wheel of the latter is at a certain angle with the axis, at first glance this inclined spoke plate seems to be able to reduce the stiffness of the connection point between the cylinder housing and the support wheel, thereby reducing its bending stress, but it is not effective in reducing the level of synthetic stress due to the increase of compressive stress, and its manufacturing process is more complicated, so it is no longer inclined to use it.

We can judge what kind of drum device to use according to the specific purpose of the hoist. The drum is generally provided with a wooden lining and the rope groove is placed on it, so as to reduce the wear caused by the direct contact between the steel rope and the cylinder shell, and make the steel rope arranged neatly. However, the service life of the wood lining is not long, and the replacement is time-consuming and material-consuming, so there are also those who do not set up the wooden lining and directly turn out the rope groove on the rolling simple shell, but this needs to increase the thickness of the cylinder shell, thereby also increasing the machine weight.

The drums of modern large and medium-sized hoists often adopt the drum structure of plate connection and angle steel connection, and their support wheels are elastic. The common feature of these two structures is the elimination of the support rings, the use of a thicker simple shell to bear the load, and the change of the support wheel to the spoked plate type or the ring type. This process is simpler, and at the same time, it can also avoid the excessive local stress of the stiffener due to improper welding process.

Abstract: The bucket elevator is suitable for lifting from low to high, and the material is automatically and continuously transported upward after the material is put into the hopper through the vibrating table. According to the amount of conveying spike socks can be adjusted, and the lifting height can be selected as needed, the hopper is designed and manufactured by itself, and the PP non-toxic hopper makes this type of bucket elevator more widely used.

Do you know the working principle of the bucket elevator and the safety regulations of the bucket elevator? Here are the introductions for you one by one. 1. What is the working principle of the bucket elevator?

Working principle: The hopper scoops up the material from the storage below, as the conveyor belt or chain is lifted to the top, it is flipped down after bypassing the top wheel, and the bucket elevator dumps the material into the receiving trough. The transmission belt of the belt driven bucket elevator generally adopts a rubber belt, which is installed on the lower or upper transmission drum and the upper and lower reversing drum.

The bucket elevator of chain drive is generally equipped with two parallel transmission chains, with a pair of transmission sprockets on or below, and a pair of reversing sprockets on or above. Bucket elevators are generally equipped with organic shells to prevent dust from flying in the bucket elevators.

2. What are the safety guessing procedures for bucket elevators?

As a widely used vertical conveying equipment, bucket elevator has been widely used in grain, feed and seed processing industries. So when you use it, will you use it correctly? What are the safety regulations for bucket elevators?

1. The hoist is maintained and managed by the designated personnel, and the key of the power switch box is managed by the designated personnel.

2. The hoist must have a winch limiter and a stroke limiter, and the limiter should make the pulley stop automatically when it is lifted to 300mm away from the drum or pulley.

3. The hoist should have a maximum load mark, and the weight should not be overloaded (1t) when lifting and landing.

4. After power transmission, check the safety devices such as the winch limiter, stroke limiter, and interlock switch, which are sensitive and reliable, and carry out test lifting.

5. Before lifting and landing, you can drive only after ringing the bell to warn.

6. The hoist is absolutely not allowed to carry people up and down.

7. After the work is completed, the hoist hanging plate should fall to the ground, and then cut off the power supply and close the upper and lower guardrail doors.

8. Always keep the environment around the hoist hygienic.

Hubei Changsheng machinery equipment is copied and manufactured.

The main technical parameters are in line with the standards of the Ministry of Machinery (JB3926-85).

NE type plate chain bucket elevator is a new type of lifting product developed by introducing foreign advanced technology; Due to energy saving and high efficiency, the NE type plate chain bucket elevator is gradually replacing the HL type equal ring chain elevator. The chain is a high-quality alloy steel high-strength plate chain, which is wear-resistant and reliable. The drive part adopts a hard tooth surface reducer.

Zhirang bucket elevator refers to the transportation equipment that continuously transports materials on the belt or chain and other traction parts. It is often used in the vertical direction or near the vertical direction to continuously improve the conveying machinery of bulk materials. Its structure is simple, covers an area small, the lifting height is large, and has the characteristics of stable work, low noise and fast speed.

The fighting elevator is composed of four parts:

1. Hopper: fixed on the tape (or traction chain), there are three main types of materials, deep bucket (suitable for loose materials), shallow bucket (viscous materials), triangular bucket (specific and lumpy materials).

2. Shell: built-in transmission device and stopper.

3. Fuselage: Thin steel plate welded into a square shell.

4. The lower part: install a tensioning device.

Summary. Hello dear, happy to answer for you; The operation process of the bucket elevator is; It is divided into three stages: the loading process, the lifting process and the unloading process.

1. Loading process: Charging is the process of digging up materials when the bucket passes through the lower part of the base. 2. Lifting process:

The process of bypassing the horizontal centerline of the bottom wheel to the horizontal centerline of the head wheel, that is, the process of the material rising vertically is called the lifting process. 3. Unloading process: The process of leaving the bucket and unloading from the discharge port when the material leaves the bucket when it passes through the upper part of the head wheel is called the unloading process.

Hello dear, happy to answer for you; The circular operation process of the bucket elevator is; It is divided into three stages: the loading process, the lifting process and the unloading process. 1. Loading process:

Charging is the process by which the bucket picks up material as it passes through the lower half of the base. 2. Lifting process: the process of bypassing the horizontal centerline of the bottom wheel to the horizontal centerline of the head wheel, that is, the process of the orange front of the material rising vertically is called the lifting process.

3. Unloading process: The process of leaving the bucket and unloading from the discharge port when the material leaves the bucket when it passes through the upper part of the head wheel is called the unloading process.

Kiss, expand for you; The bucket elevator structure is composed of four parts, 1, disturbing the hopper: deep bucket, shallow bucket, triangle bucket 2, shell: built-in transmission device and brake trapped wide.

The characteristics of the bucket elevator are; 1. The driving power is small, the conveying capacity is large, and the inflow feeding, induced unloading and large-capacity hopper intensive arrangement are adopted. 2. The lifting range is wide, and this kind of elevator has few requirements for the type and characteristics of the material, which can not only improve the general powdery and small granular materials, but also improve the materials with greater abrasiveness. Good sealing, less environmental pollution.

Bucket elevator is the most common vertical conveying equipment, and it is the most effective way to lift granular and powdery materials. It is mainly composed of a head, a barrel, a base, a bucket belt, a bucket, a transmission mechanism and a tensioning device. Depending on the need, it can also be equipped with protection devices such as anti-reverse, explosion-proof, speed sensor and deviation monitor.

The advantage of the bucket elevator is that it can convey materials in the vertical direction, so it occupies a small area and significantly saves the floor space; Able to work in a fully enclosed enclosure without raising dust; It is adaptable and energy-saving, and its energy consumption is only 1 10 1 5 of pneumatic transmission. The main disadvantage is that the types of materials to be conveyed are limited, and they are only suitable for bulk materials and broken materials; The susceptibility to overload is high, and the material must be fed evenly to prevent clogging.

Advantages: simple structure, small footprint in the plane, large conveying capacity, high conveying height (generally 12 32m, up to 80m), simple manufacturing process and structure, good sealing performance, convenient management, simple operation and maintenance, etc. It is widely used for vertical conveying of lumpy, granular and powdery materials.

Disadvantages: large sensitivity to overload, material must be supplied evenly, buckets and chains are easily damaged.

Types of bucket elevators.

1.According to the layout form: it can be divided into two types: vertical type and inclined type.

2.According to the different discharge methods: it can be divided into centrifugal type, gravity type and mixed type.

3.According to the different charging methods: it can be divided into digging type and injection type.

4.According to the structure of the hopper: it can be divided into shallow bucket, deep bucket and triangular bucket.

5.According to the different traction members: it can be divided into tape and steel chain.

Among them, inclined and vertical types are more commonly used. Inclined bucket elevator in order to change the height of material conveying to adapt.

The needs of different provinces exceed the situation. There is a detachable section in the middle of the hopper groove, so that the elevator can be extended or shortened. Brackets also.

is retractable and fastened with screws. The vertical bucket elevator is mainly composed of a hopper traction belt, a driving device, a casing and a feed and discharge port.

1. Bucket elevator.

Comparison with general conveyors:

1. The general conveyor has a belt and an electric combustion conveyor.

Screw conveyors, etc., they are generally horizontal. The belt conveyor is conveyed horizontally by using belts (belts), rollers, motors, etc. The screw conveyor is conveyed by using the rotation of the spiral blades.

2. The bucket elevator is used in the vertical direction or at a large inclination angle.

It is a widely used vertical conveying equipment for transporting various bulk particles and crushed materials. The hoist is a vertical conveyor, using a belt or iron chain to connect a hopper (welded with iron plates) to convey a variety of different materials, and then equipped with a drive device (including some accessories such as motors).

Second, compared with the general conveyor, what are the advantages of the bucket elevator?

1. Compared with other conveyors, it can convey materials in the vertical direction and occupies a smaller area;

2. When the same lifting height, the conveying route is greatly shortened, so that the layout of the system is compact;

3. Work in a fully enclosed shell, which has good sealing, so as to reduce the pollution to the environment.

Structure: The bucket elevator is mainly composed of traction components (bucket belt), hopper (bucket), head, barrel, base, drive device and tensioning device. The whole bucket elevator is formed by an external casing to form a closed structure, the upper part of the casing is the head, the middle part is the barrel, and the lower part is the base.

The barrel can be composed of several sections according to the different lifting heights. The internal structure is mainly a bucket belt that forms a closed annular structure around the nose wheel and the base bottom wheel, and the bucket belt is installed at certain intervals for carrying materials. The driving device of the bucket elevator is arranged at the head position, and the drive of the bucket elevator is realized through the head wheel, which is used to realize the tensioning of the bucket belt, and the tensioning device that ensures that the bucket has sufficient tension is located on the base shell.

In addition, in order to prevent the reversal of the bucket belt, an inversion stopper is set on the head wheel; The barrel is equipped with a bucket belt deviation alarm, and the bucket belt can be alarmed in time when the bucket belt is deviated; A speed difference monitor is installed on the bottom axle to prevent the bucket belt from slipping; An explosion vent hole is set on the head shell to relieve the pressure of the sealing space in time and prevent the occurrence of dust. The above special components are set up to ensure the normal and safe operation of the bucket elevator.

Working process:

1. Loading: Charging is the process of digging up materials when the bucket passes through the lower part of the base.

2. Lifting: The process of the bucket bypassing the horizontal center line of the bottom wheel to the horizontal center line of the head wheel, that is, the process of the material rising vertically with the bucket is called the lifting process.

3.Unloading: The process of leaving the bucket and unloading from the discharge port when the material leaves the bucket when it passes through the upper part of the head wheel is called the unloading process.

There are three types of discharging methods: centrifugal type, gravity type and mixed type. Centrifugal type is suitable for materials with good fluidity and scattering, and gravity discharging should be used for materials with more moisture content and poor scattering, and mixed discharging has better adaptability to materials, and is more commonly used in engineering practice.

Bucket elevator introduction: As a widely used vertical conveying equipment, bucket elevator has been widely used in grain, feed and seed processing industries.
