Powder tanks are used to transport coal fly ash, cement, lime powder, mineral powder and granular base powder materials such as semi-trailer, by car chassis and powder bulk transport special device of two parts, special powder bulk transport device and include additional transmission system, tank assembly, piping system, accessory device four parts, using powder fluidization for powder material transportation. Below and Custom semi trailer manufacturers
Let's take a look at the inner structure and working principle of the powder truck.
One, what is the use of a powder tanker?
Powder tank truck is a semi trailer. Its full name is powder material transport truck, suitable for fly ash, cement, lime powder, ore powder, particle alkali particle diameter is not greater than 0.1mm powder dry material bulk transport, it is a professional car.
Two, what is the internal structure of the powder tank car
The structure of the powder tank car is more complex, can be roughly divided into two parts: chassis and powder bulk transport device: car chassis is the bottom of the car, powder bulk transport device mainly includes additional transmission system, tank assembly, piping system, auxiliary device four parts:
1. Additional transmission system: it mainly includes force extractor, additional transmission shaft, air compressor, etc.
2, tanks assembly: the body of the powder tank car, used for loading powder, tanks in accordance with the class number can be divided into three tank and tank, has the variety of shapes such as round, oval, square shape, the tank is mainly composed of head, cylinder, manhole covers and fluidization device and so on, which core part is internal flow device, semi-trailer adopts breathable belt type fluidized device.
3. Piping system: including inlet pipe, secondary auxiliary blowing pipe, discharging pipe, external air source, pressure relief valve, etc.
4. Accessory devices: including side protection, rear protection, wheel cover, ladder climbing, etc.
Three, what is the working principle of the powder tanker?
Powder tank car mainly uses the fluidization characteristics of powder to achieve unloading, powder fluidization refers to: When the gas from the lower part of the container into the powder layer, if the gas velocity exceeds a certain value (cement of 0.015 m/s), the friction of the gas and powder body equals the weight of powder, granule, powder, granule no longer rely on the fluidized bed, this time they can move freely, flow from high to low, make the powder layer on the surface level, similar to the nature of the liquid. The specific working principle is:
The power of the engine of the powder truck is transferred to the air compressor by the force extractor, the driving shaft and additional mobile devices. The compressed air generated by the air compressor enters the tank, and the powder material is liquefied by the liquefaction device. The powder material is transported to the specified position along the unloading pipeline with the air due to the pressure difference between the inside and outside of the tank.
