The traditional way of cement transportation process will produce a large number of production divided into a large number of transport packaging box unpacking work, labor costs, low efficiency and the human body is very harmful, not enough to support the use of large cement plants as well as construction projects.
Powder tanker （Powder material transport truck） can perfectly solve the above problems. So how do you need to operate when using the powder granular material transport truck, now give you 9 steps to operate correctly.
Operation method of powder granular material truck
Before transporting the powder material, you should first check and clean the ash inside the tank and the pipes, which has the advantage of preventing the ash from crowding the original space, increasing the loading capacity and speeding up the loading and unloading. This is very important for the bulk cement truck which has a long service life. It doesn’t matter if the truck is new, just pay attention to the tank moisture and waterproof. Also check that the valve should be flexible and not stuck or leaky, and that the pipe is not broken.
When loading materials
When opening the loading port at the top of the tank of the powder granular material transport truck, the exhaust valve should be opened first, because there is residual gas in the tank with pressure, if you open the loading port, it may cause the operator to fall or eye injury.
When loading materials
Should open the level switch in the powder tank, when the level signal is full, should immediately stop loading, so as not to cause material loss.
After the material is loaded
Should be the top of the tank loading mouth edge gauge of the powder clean, to prevent the powder hardened by water sticky loading cover, affect the opening and closing, after cleaning to close the loading mouth in time and lock the cover, moisture.
Before unloading the Powder tanker vehicle
- Firstly, park the car in a relatively flat position, take out the discharge pipe, close the butterfly valve of the discharge pipe and the ball valve of the discharge pressure pipe.
Open the secondary air pipe and connect the compressed air, let the air compressor start under no load can prolong the service life of the air compressor. - Turn on the air compressor and pressurize the air to the powder tank, the discharge valve can not be opened at this time.
- When the pressure increases and reaches the fluidization state of the powder in the unloading pressure tank, you can slightly open the secondary air nozzle valve and the unloading valve, and adjust the size of the opening of the secondary air nozzle valve to achieve the best ratio of powder and air
In the process of unloading
The change of pressure gauge should be checked at any time, if there is a sudden increase in pressure. It means that the discharge pipe is blocked. At this time should stop sending air to clear out first. When unloading the powder material truck, arrange a person to be responsible for opening,
When pressurizing air
Do not change the speed of the internal combustion engine. When the unloading is finished, open the air release valve. Try to release the pressurized air in the tank. Then close all valves.
When it is raining, foggy and so on, the humidity is too big
It is not allowed to load or unload in the open air to prevent the caking of powder particles in the tank, and the sealing of the inlet cover on the top of the tank should be checked regularly to see if it is tightly closed. Do not allow water or wet air to enter the tank.
The air compressor should be checked regularly
As the most important equipment of powder tanker, the good or bad of air compressor is directly related to the speed and efficiency of loading and unloading, in addition, regular maintenance can prolong the service life.
