One of the two methods of lime storage tanks is to use lime trucks for transportation. The lime truck, also known as the powder material transport truck, consists of a dedicated automobile chassis, a lime silo tank, a gas pipeline system and an automatic unloading device. It is suitable for the transportation of fly ash, cement, lime, powdered ore, powdered alkali metals and other dry materials with a particle size not greater than 0.1mm. When using a lime transporter to feed materials, you must pay attention to the correct operation to ensure the safe use of the machine and the safety of personnel.
Before unloading the lime storage tank, first stop the car in a relatively flat position, remove the discharge pipe, and then close the discharge pipe butterfly valve and pressure relief pipe ball valve. Open the secondary air pipe and connect the compressed air so that the air compressor can be started under no load, thereby prolonging the service life of the air compressor. At this time, the air compressor is turned on and the air is pressurized to the powder tank. At this time, the discharge valve cannot be opened. When the pressure rises and reaches the fluidized state of discharging the powder in the pressure tank, the secondary air nozzle valve and the discharge valve can be opened slightly, and the opening degree of the secondary air nozzle valve can be adjusted to obtain powder and air. Largely. The ratio is good.
During the discharge process, the cement tank should be checked at any time. If the pressure suddenly rises, the discharge pipe will be blocked. At this point, you should first stop the inflation to clean the pipe. After the discharge is complete, open the exhaust valve, try to discharge the compressed air in the water tank, and then close each valve.
When there is too much rain (such as rain or mist), it is not allowed to be discharged outdoors to prevent the lime particles from solidifying. The seal of the inlet cap on the top of the lime storage tank should be checked frequently. Whether to close. Do not allow water or humid air to enter the lime storage tank.
The lime storage tank is part of the entire mixing system. The weighing system does not seem to be directly related to the lime storage tank, but it will affect the storage capacity of the entire lime storage tank, and the quality of the material may even damage the entire lime storage tank.
If there is a weighing error in the weighing system, the original concrete material will change. On the one hand, the quality of the concrete produced will change. If this change is large, the inner wall of the lime storage tank may be damaged. The materials of different densities in the lime storage tank are different. Once the weighing system fails, it is easy to slow down the material or even block the lime storage tank.
In addition, if there is a weighing error in the weighing system of the lime storage tank company, the amount of concrete produced may be different from the plan, and because the entire mixing equipment is automated and streamlined, the weighing error is caused The materials are also very different. In this case, the actual material storage capacity in the lime storage tank is greater than its theoretically large storage capacity, which may cause the lime storage tank to tilt and trip.
As we all know, the lime storage tank is supported by thin feet, and the height of the lime storage tank is relatively high. The outriggers must not only bear the weight of the cement tank, but also the weight of the material, so the weighing is very large, and sometimes it needs to withstand strong winds and other factors. Therefore, the safe work of the lime storage tank is required. In addition to the necessary installation, wind speed factors also need to be considered.
