With the continuous development of my country's economy, the scale of cities is gradually expanding. In the process of urbanization project construction, cement is a necessary building material. To transport these cement dust accurately to the destination, a dust material transport truck is needed.
Dust material transport vehicles, also called powder tankers, are mainly used to transport dry dust materials with a diameter of not more than 0.1mm, such as cement, fly ash, lime powder and other materials.
In my country’s cement transportation market, the first to appear is a gravity unloading truck, which is like the new type of dump truck with a roof. When unloading, the cargo compartment rises and the materials are discharged by gravity. This unloading method The disadvantage is that it can only unload materials to a position lower than its own cargo compartment.
In the 1950s, there were new changes in the cement transportation market. Screw conveyors mounted on trucks can be used to unload materials, but this unloading method is likely to cause damage to the ash unloader, so it is not ideal. Unloading plan.
It was not until the 1960s that the emergence of pneumatic ash unloading trucks ideally solved the problem of dust material unloading.
This material unloading method is that the air compressor is powered by a diesel engine, and the gas compressed by the compressor is transported to the inside of the tank through the intake pipe, and the fluidity of the dust material is increased through the fluidization device, showing a liquid-like nature. The powder can flow on a fluidized bed with a certain inclination angle.
Due to the pressure difference between the inside and outside of the tank, when the material is unloaded, the valve is opened, and the dust material will be transported to the designated position along the unloading pipeline along with the air.
