The powdered material transport vehicle is believed to be in contact with everybody, but for people who have not come into contact with the powdered material transporter, the structure of the powdered material transporter and the main role of each part is what they do. I believe it will not be known. More than that, Xiao Bian found some information on the structure and principles of the powdered material transporter on the Internet and sorted it out, hoping to help everyone understand.
â— The five major components of the powder material transporter
Five components of the powder material transporter
The powder and grain material transport vehicle is mainly composed of a chassis and a top-loading part, and can be simply divided into five parts: a chassis system, a transmission system, a tank body, a pipeline system, and an accessory.
1. Chassis system: The main component of the powder material transporter is the transport function of the powder and grain material transport vehicle. In the form of semi-trailer tractors, the pulverized material transporter is driven by a tractor to drive the powdered material semi-trailer to achieve the transport function.
2. Transmission system: It mainly consists of power take-off devices, transmission shafts and air compressors. It can also be equipped with a dual power system powered by a chassis gearbox and an external motor. Semi-trailer material transport vehicles are generally equipped with an external motor to provide power. The power take-off device is powered by an engine or an external motor, and the air compressor is driven by the drive shaft to pump and pressurize the tank to discharge the cargo. The power of the air compressor largely determines the speed efficiency of the unloading.
3, tank: Mainly by the head, cylinder, manhole cover and fluidization device and other components. It is the carrying part of the loading cargo. The horizontal type of the tank can be generally divided into three compartments and double compartments. The vertical type is generally a multiple compartment structure. The material of the tank body is usually carbon steel, stainless steel, aluminum alloy, etc. The materials used for the different transport medium requirements and the internal processing of the tank body are also different. The excellent design of the tank body also determines the discharge speed and the residual material rate.
4. Piping system: It is mainly composed of two parts, the intake pipe and the unloading pipe. After the gas is output by the air compressor, it passes through the check valve and ball valve to enter each chamber. The unloading pipeline mainly consists of suction port, butterfly valve, unloading steel pipe, unloading pipe joint, unloading rubber pipe and so on.
5. Attachment system: It mainly includes side protection, rear protection, wheel cover, ladder and so on.
â— The working principle of powder material transporter
Powder particle transporter working principle
The power of the car engine (or external motor) is transmitted to the air compressor via a power take-off device, a transmission shaft, and other transmission devices. The compressed air (or external compressed air) generated by the air compressor enters the tank body and passes through the fluidization device. Due to the pressure difference between the inside and the outside of the tank, the powder and granular materials are fluidized along with the air along the discharge pipeline to the storage tank outside the tank.
The principle of fluidization of powdered materials
After the pressurized gas from the air compressor enters the powder layer from the lower part of the tank, when the gas flow rate exceeds a certain value (the value of different materials is different, the cement is 0.015m/s), and the gravity-reducing effect of the particulates is similar to suspension. When they are free to move from high to low, similar to the nature of the liquid, they are ejected from the discharge hole. This is called the phenomenon of fluidization of the powder, which is called the phenomenon of fluidization of the powder.
Among these, the role of the bottom fluidized cloth breathable belt in the tank is to make the compressed air form a fine and uniform air flow into the powder layer to fluidize the powder.
Strong all over the body of Shopping Trolley, which can protect the goods and effectively withstand the external impact on the goods.
The function of folding and stacking is added on the original turnover, which can effectively reduce the floor area and avoid nowhere to be placed in the situation that is not available, which is also one of the advantages of folding and stacking turnover boxes.
