What is the reason why the mixer can t stir the same concrete as before?

The working principle of the mixer: it is composed of a horizontally rotating container and rotating vertical stirring blades, etc., when the forming material is stirred, the container turns to the left, the blade turns to the right, due to the effect of countercurrent, the movement direction between the particles of the forming material is crossed, and the opportunity of mutual contact increases, the extrusion force of the countercurrent mixer on the material is small, the calorific value is low, the mixing efficiency is high, and the mixing is relatively uniform. Mixer principle:

Centrifugal principle, when the floating liquid containing fine particles is stationary, the floating particles gradually sink due to the action of the gravitational field. The heavier the particle, the faster it sinks, and conversely, the particle with a smaller density than the liquid will float.

The purpose is to prevent concrete from agglomerating during transportation and to make sand, stone and cement mix more evenly in concrete

Concrete has the characteristics of abundant raw materials, low cost and simple production process, so that the amount of concrete is getting larger and larger. At the same time, concrete also has the characteristics of high compressive strength, good durability and wide range of strength grades. These characteristics make it widely used, not only in various civil engineering projects, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc., concrete is also an important material.

History. Archaeologists have found that 5,000 years ago, the ancestors of Lingjiatan were not only able to make exquisite jade tools, but also began rice farming, raising or hunting pigs, deer, birds and poultry and other animals to enrich the diet of varieties. In addition, in the construction of houses, they have learned similar to reinforced concrete: "digging grooves to fill the soil, wood bones to support the mud wall" construction technology.

5,000 years is not just a simple way to build houses, at that time Lingjiatan people already knew the construction process of "digging grooves and filling soil, wood bones supporting mud walls", which is very similar to today's reinforced concrete. The staff said that the primitive ancestors used the fire-burned soil as the filling material for the foundation groove and the wall, used wooden sticks as the support column of the wall in the foundation groove, and then filled the red-burned soil blocks, and mud on both sides of the wall, and even some of them may be reinforced with reed rods.

That's because the concrete mixer truck is loaded with concrete, once it stops rotating, the concrete in the tank will solidify in the tank and cannot be discharged, and the concrete can not be decomposed in the mixer tank, the tank of the concrete mixer truck will be scrapped, and a new tank needs to be replaced.

The power is output by the full-power power take-off of the second-class chassis and transmits the power to the hydraulic pump through the transmission shaft, and the hydraulic pump generates hydraulic energy and transmits it to the hydraulic motor through the oil pipe, and the hydraulic motor converts the hydraulic energy into kinetic energy and transmits it to the mixing tank through the deceleration and torque increase of the reducer.

By adjusting the angle of the servo handle of the hydraulic pump (double-acting variable), the positive and negative rotation of the mixing tank and the size of the speed can be realized, so as to realize the operation of concrete loading, stirring, agitation, and discharging.

Agitator:

It is mainly composed of a stirring drum and its auxiliary support parts. The mixing drum is a loading container for concrete, which is made of high-quality wear-resistant thin steel plate, in order to be able to load and unload concrete automatically, its inner wall is welded with spiral blades of special shapes. When turning, the concrete moves in the spiral direction of the blades, and is mixed and stirred during the continuous lifting and turning process.

In the process of feeding and transportation, the mixing drum rotates forward, and the concrete moves inward along the blade, and when discharging, the mixing drum is reversed, and the concrete is discharged outward along the blade. The rotation of the mixing drum is ensured by a hydraulic drive. The loading capacity is 3 6 cubic meters.

The concrete mixer truck generally adopts a hydraulic pump driven by the automobile engine through the power take-off shaft.

Prevents concrete segregation and makes the concrete more homogeneous. In addition, if the concrete is stagnant for a long time, and the vehicle shakes again, the concrete will soon become dense, and finally the tank will not be able to rotate.

The selection of defoaming mixer needs to consider the applicable materials, layout form, each processing capacity range, mixer type, material type, application field, mixing method, motor power, production capacity and other factors, such as applicable materials are chemicals, solder paste, glue, medicine, ink, etc.; The application fields are chemical, decoration, pharmaceutical, chemical, plastic and rubber, etc.; The layout forms include vertical, horizontal, coaxial, etc. The ** of the degassing mixer is about tens of thousands of yuan per unit, and the cheap one is one or two thousand yuan. Before you choose, it is recommended that you have a full understanding and comparison of the degassing mixer, and the specific and more professional answers can be contacted by Mianyang Shinuo Technology****, product service:

The blender has brought great convenience to our life, which can grind meat, stir fruits and stir whole grains.

It can make a lot of delicious food, but the blender, like other household appliances, may also have various problems after use, such as the common problem is that the blender does not rotate, so what is the reason why the household blender does not rotate? Let's take a look.

If the household blender does not turn, first check the electrical outlet.

Whether it is powered or not, if there is no electricity, the mixer will definitely not work; It also depends on whether the switch of the blender is turned on, and it will definitely not work if it is not turned onIt is also possible that the stirring rod on the mixer is not installed properly, and the mixer has a safety protection device, and it will not rotate if there is an abnormality.

If these are normal, it is recommended that it is best to take it to a professional maintenance personnel for overhaul, and do not disassemble the mixer without authorization to avoid causing more serious damage. Many mixers are due to a short circuit in the rotor part of the motor or a short circuit in the commutator, because if the mixer works for too long, it will cause the temperature rise of the motor to be too high, so the mixer should not be used for too long each time.

You need to pay attention to the fact that before using the blender, it must be installed in place before it can be used safely. After the mixer is used up, it must be cleaned in time, you can put a few drops of detergent and appropriate warm water when cleaning, the detergent can not be put too much, and then directly turn on the mixer, let it start stirring, stir for a few minutes and then wash it with running water, and put it in a ventilated place to dry.

Summary. Hello: There are many reasons why the mixer does not rotate, it may be that the machine has a short circuit fault, the lubricating oil pump does not work normally, the bearing is damaged, the mixer shaft rotates in the opposite direction, the mixer automatically trips and loses power, etc.

A mixer is a machine with a vane shaft that rotates in a drum or tank to mix a variety of ingredients into a mixture or a suitable consistency. The main production task of the mixer is to mix cement, concrete, etc. The mixing blades in the mixer accessories can promote the friction and collision between the particles of the mixed material, and the material is more fully mixed.

What is the reason why the dough mixer does not turn.

If it's not because the dough is too big to stir, see if the bread bucket is placed correctly, or tighten it clockwise after putting it in. If it doesn't work, you see if you don't put anything in the bread bucket, can you turn the stirring rod with your hand, if it doesn't work, just find customer service Flour mixer operating procedures: 1 Clean the dough mixer before use, put in flour and water, don't overdo it so as not to damage the machine, if you need to mix more noodles, you need to stir it 2 times or more.

After the surface and water are placed, close the baffle and then turn on the power. 2 When mixing the dough, stir in both directions so that the dough is evenly mixed. 3. If the mixing is uneven or when it falls into the dirt, it is necessary to adjust or take the noodles by hand, and the power must be turned off first.

4 After stirring, turn off the power and take the noodles after stopping. Clean up the residue one at a time. 5. Do not thin the dough in the dough mixer to prevent corrosion of the dough mixer.

6. If a fault such as leakage is found, the power supply should be cut off immediately, and an electrician should be found for repair, and the machine should not be repaired without permission. 7 Before use, refer to the instructions for use. If you do not use it strictly in accordance with the operating procedures, you will be responsible for the consequences if there is a problem.

What is the reason why the mixer can not be on it, ask for advice.

Hello, when the mixer hopper cannot be raised during use, there are generally several possibilities: overload, small motor, loose belt, or long-term lack of maintenance of the drum mixer. Exclusion Method:

1. Check whether the hopper lifting motor can be started, if not, check the power cord start switch, etc.; 2. If the hopper lifting motor can be started, check the electromagnetic relay reducer (some mixers are mechanical reducers), which are generally caused by the broken electromagnetic coil and the serious wear of the damping plate.

Summary. The possible reasons why the mixer does not move are: the switch button of the air compressor is not opened, or the circuit breaker is not connected, and the main engine access door is not closed.

The solution is to check all these places and solve any problems. The lube oil pump is not working properly. The reason is that the power cord is faulty and cannot transmit the current normally; or the motor in the lubricating oil pump is faulty or short-circuited; The solution is to replace the power cord and see if it is possible.

The vehicle transporting concrete keeps turning because it can automatically turn within a certain range to ensure the uniform distribution of concrete.

The vehicle transporting the concrete loads the concrete into a large mixing tank, and then the mixer turns inside the tank to ensure the even distribution of the concrete. The speed of the mixer is related to the consistency of the concrete, and when the consistency of the concrete increases, the speed of the mixer will also increase. In addition, the speed of the mixer also depends on the quantity of concrete, and when the quantity of concrete increases, the speed of the mixer will also increase.

The vehicle transporting concrete keeps turning because it can automatically control the speed of the mixer to ensure the uniform distribution of concrete. The vehicle transporting concrete also has an automatic control function, which can automatically adjust the speed of the mixer according to the needs of the concrete to ensure the uniform distribution of concrete.

The reason why the concrete mixer truck is made oval:

Domestic Zhongtong mixer concrete mixer truck (cement mixer, concrete mixer) is a special truck used to transport concrete for construction; Due to its appearance, it is also often referred to as a snail car. These trucks are equipped with cylindrical mixing drums to carry the mixed demolition concrete. The mixing drum is always kept rotating during transportation to ensure that the concrete carried does not solidify.

After transporting concrete, the inside of the mixing drum is usually washed with water to prevent the hardened concrete from taking up space, so that the volume of the mixing drum is getting smaller and smaller.

Considering the stability of the material when the car is driving (the center of the circle is always downward) and the concrete in the drum needs to be randomly mixed during the transportation process to ensure that it is uniform and not segregated to sell the fire, etc., the concrete mixer truck is made into a round drum shape.

The main reason why the concrete mixer truck rotates on the road is to prevent the concrete from agglomerating during transportation and to make the sand, stone and cement in the concrete mix more evenly.

1. In order to obtain the best concrete ratio and quality and reduce the occupation of the construction site, improve the construction progress of the house and shorten the construction period, for the construction of high-rise buildings, the concrete has evolved from the original construction site to a more advanced production and distribution system of the concrete company;

2. After the concrete mixer truck is loaded in the concrete company, because there is a relatively long transportation distance from the loading truck to the construction site, in order to prevent the concrete from agglomerating during transportation, a certain amount of retarder is added to the formula of the prepared concrete;

3. If the concrete mixer truck does not mix, during the transportation process, the stones in the concrete will sink to the bottom layer, the middle layer is sand, the upper layer is cement slurry, and the phenomenon of agglomeration will occur after transportation to the construction site, therefore, the rotation of the concrete mixer truck during transportation can not only prevent concrete agglomeration, but also prevent concrete delamination, so that the concrete is mixed more evenly.
