With the development of urban construction, the use of cement has become more and more frequent, which has led to the rapid development of pneumatic trailers and their wider application.
What is the pneumatic trailer?
A pneumatic cement trailer is a type of trailer used to transport dry bulk cement, sand, and other dry bulk materials. The trailer utilizes compressed air to move the material through the trailer and out of the discharge chute. Pneumatic trailers are often used in the construction industry and concrete mixing plants.
Pneumatic truck unloading systems
The pneumatic truck unloading system mainly includes air compressor, blower, piping, valves and hoses.
Air compressor: The main function of an air compressor is to compress the air.
Pneumatic truck blower: The blower will compress the air into the inside of the tank through the pipeline.
Valve: The valve is mainly divided into help blowing valve, safety valve, general valve and unloading butterfly valve.
Hose: The hose is mainly used to connect the cement trailer and mixing bin, so that the cement can be unloaded to the designated position.
How does dry bulk trailer work?
Loading and unloading is a very important thing for pneumatic trailer, loading needs to drive the dry bulk trailer to the designated place, after loading, transport the cement to the destination, and then unloading.
How does pneumatic trailer loading
- Before loading, the first thing we should check is the exhaust valve, this step is very important to prevent the cement trailer from having pressure without finishing unloading.
- After making sure the exhaust valve is open, open the manhole cover and then start loading.
- After the loading is finished, we should clean the seal, clean the cement on the seal, and then tighten the manhole cover.
- After finishing, you should close the exhaust valve and discharge butterfly valve to prevent the cement inside the tank from getting wet.
How does dry bulk trailer unloading?
- Firstly, connect the hose to the mixing bin or the designated location to make sure the connection is strong to prevent it from falling off during the unloading process.
- Start the air compressor, run it smoothly first, then gradually increase the horsepower to make the air compressor reach the rated speed, so as to start adding pressure to the inside of the tank.
- We can observe the pressure inside the tank through the pressure gauge, when the pressure reaches 0.15Mpa, you should open the secondary air ball valve to unclog the discharge pipe, make sure the discharge pipe is not blocked, and then close the secondary air ball valve.
- When the internal pressure of the tank reaches 0.2Mpa, it is time to start unloading officially and open the unloading butterfly valve.
- When unloading, the air compressor is working all the time, so the pressure inside the tank will not be reduced.
- When unloading, you can unload the second half of the cargo first, and then unload the first half of the cargo, just close the front valve first.
- When no cargo is unloaded, it means that the unloading is finished.
- The last step is to confirm that there is no residue, then you can turn off the air compressor, then open the exhaust valve, close the unloading butterfly valve, unload the quick interface, take off the hose and put it back into the car, then you can finish the unloading work.
