What is the difference between HL hoist and TH hoist

The HL type ring chain centrifugal bucket elevator is composed of a moving part (hopper and traction chain), an upper section with a transmission sprocket, a lower section with a tensioning pulley, an intermediate casing, a driving device, a backstop brake device, etc. The hopper of the hoist is arranged intermittently, and the "digging method" is used for loading and the "centrifugal feeding method" is used for unloading. The traction mechanism of this hoist is two ring chains.

There are 4 differences between TH-type bucket elevator and HL-type bucket elevator: 1. The conveying capacity is large, which is nearly double that of the HL type (139) 2. The wheel body and the rim are made of combined sprockets, which are easy to replace and save costs (373) 3. The chain is made of low-alloy steel after special forging and heat treatment. Long service life, high strength, wear-resistant (45) 4, the lower part adopts gravity automatic tensioning device to avoid slippage and disconnection, and reduce maintenance.

477) 5. Mixed and gravity unloading are adopted.

1、tdBucket elevatorThe materials that can be transported, the TH bucket elevator can be transported.

2. Because the TD bucket elevator is transported by belt, the temperature required for the material cannot exceed 60 degrees.

TH bucket elevator is used for chain conveying, so the temperature can reach up to 250 degrees 3, TD has harsh requirements for materials, but the cost is lower than that of TH bucket elevator, TH bucket elevator is between the NE elevator and TD bucket elevator, and the cost is higher than that of TD.

TD type bucket elevator is equipped with four types of hopper: Q type (shallow bucket), H type (arc bottom bucket), Zd type (medium and deep bucket), SD type (deep bucket). TD roughly means: lifting.

What is the model of about 150 tons per hour.

TH series bucket elevator is a substitute product for HL type bucket elevator designed and produced according to national standards, which has high lifting height, large conveying capacity and long service life that HL type elevator cannot reach. Different from the HL type elevator, the traction parts of the TH-type bucket elevator are made of high-strength circular chains, which are heat-treated, with high-strength tensile resistance and wear resistance, and the traction parts have a longer service life.

The lower part of the hoist adopts a heavy hammer lever tensioning device, which can automatically maintain the constant tension force, and can avoid the chain bucket slipping or detachment during operation. It is conducive to the normal and stable operation of the equipment.

The common TH series bucket elevator hopper has medium deep bucket and deep bucket, among which the medium and deep bucket type is more difficult to throw out in order to convey high humidity and viscosity, such as wet sand, fertilizer, alkali surface, clay and other materials. The deep bucket is used to transport materials with good dryness, such as coal, gravel, cement raw meal, slag and cement, etc., which are easy to throw out.

Most of the TH series hoists adopt the loading and mixing discharging method.

There are many kinds of elevators, among which the belt drive bucket elevator is suitable for materials with good fluidity such as grain. As for the difference between this hoist and other hoists? There are mainly differences in transmission, chain belt, suitable material types, material particles, etc.

The chain belt bucket elevator is suitable for materials with certain particles such as coal.

Hello, Wuhu Qiyun special eggplant industry produces all kinds of hoists About the advantages and disadvantages of the NSE hoist compared with the Wang Zhichath hoist, you can go to their network to shout which station to ask professionals to answer.

TD—Belt bucket elevator.

NE—Plate chain bucket elevator.

th—chain bucket elevator.

HL—Ring chain centrifugal bucket elevator.

TB—Vertical bucket elevator.

DZC—Vertical Vibrating Bucket Elevator.

Shanghai Kelirick hoist mainly has TH series bucket elevator, TB series bucket elevator, if you need it.

As a commonly used lifting equipment, it has been widely used in many fields. With the increase of its application, it has also promoted its continuous development. What are the categories of bucket elevators according to the transmission structure?

1).TD series bucket lift.

TD series bucket elevator is a national standard bucket elevator, TD series bucket elevator is based on D series bucket elevator through product improvement, its specifications are TD100 (not commonly used), TD160, TD250, TD315, TD400, TD500, TD630, TD800, TD1000 and other models, of which TD160, TD250, TD315 and other models are commonly used models.

2).TH series bucket elevator.

Th series bucket elevator is commonly used lifting equipment, this series of bucket elevator adopts forging chain as the transmission part, has strong mechanical strength, mainly used for elevator powder and small particles and small block materials, different from TD series bucket elevator, its lifting capacity is larger, higher operation efficiency. It is often used for the lifting of materials with a large specific gravity.

3).NE series bucket elevator.

NE series bucket elevator is a new type of bucket elevator, which adopts plate chain drive, which is different from the old model TB series plate chain bucket elevator, and its naming method is named after the lifting amount rather than the bucket width. NE series bucket elevator has a high hoist efficiency, according to different lifting speeds, there are also NSE models and high-speed plate chain bucket elevators.

4).TG series bucket elevator.

TG series bucket elevator is a reinforced belt bucket elevator, which is different from TD series bucket elevator, TG series bucket elevator uses steel wire tape as the transmission belt, which has stronger transmission capacity. This series of bucket elevators are mostly used in grain transportation, and are also known as special bucket elevators for grain.

5).Other models of bucket elevators.

Common bucket elevator models also include HL series bucket elevator, GTD series bucket elevator, GTH series bucket elevator, TB series bucket elevator, etc., which are different names and evolution forms of the above models.

TD type belt bucket elevator, TH type ring chain bucket elevator (the old model is HL type), TB type plate sleeve roller bucket elevator.

The old model is PL type) TZD type belt bucket elevator.

The letters in front represent different bucket types; Q type (shallow bucket), H type (arc bottom bucket), ZH type (medium and deep bucket), SH type (deep bucket).

Belt bucket elevator, plate chain bucket elevator, chain bucket elevator.

There are different types of bucket elevators, and the common ones are classified according to the traction parts and according to the unloading method. According to the former, it can be divided into several types, such as ring chain type, plate chain type and tape. According to the latter, it can be divided into three types: centrifugal discharge, gravity discharge and mixed discharge.

The structure of the chain bucket elevator is relatively simple, and the link between the hoppers is also relatively firm, and the wear of the chain is small when conveying materials with relatively large abrasiveness, but the weight is relatively large. The plate chain bucket elevator is light in weight and strong in structure, because the hinged joint is easy to be worn, the mechanism of the tape is very simple, so it is not suitable for conveying abrasive materials. The temperature of the material conveyed by the ordinary belt elevator cannot exceed 60 degrees Celsius.

The steel rope belt hoist conveys materials not exceeding 80 degrees Celsius. The heat-resistant tape can convey materials with a temperature of no higher than 120 degrees Celsius, and the plate chain elevator can convey materials below 250 degrees Celsius.

The most commonly used in daily industrial activities are belt bucket elevators and chain bucket elevators. Different materials are conveyed to have different requirements for the hoist, for example, the conveying of bulk cement requires the use of deep hoppers. Each cubic meter of powdered granular material needs to use a TD belt bucket elevator of centrifugal discharge or mixed discharge type.

The bucket speed of the centrifugal discharge elevator is relatively fast, and it performs well in conveying powdery, granular and small pieces of materials with little abrasiveness. The bucket speed of gravity bucket elevator is relatively slow, and it is mainly used in blocky, heavy, and abrasive materials, such as limestone, clinker, etc.

Vertical dump elevator: lifting height from 2m to 20m, power from, maximum lifting weight up to 2000kg.
