Since the concrete will solidify into a hard block in a short time, and has certain corrosivity to steel and paint, it is a daily maintenance work to clean the concrete adhered to the concrete storage tank and the inlet and outlet after each use of the concrete tank. These include:
1. Flush the feed inlet with water before each loading to keep it moist during loading;
2. At the same time of loading, fill the cleaning water tank attached with the vehicle with water;
3. After loading, wash the inlet to clean the residual concrete near the inlet;
4. After unloading at the construction site, wash the discharge tank, and then add 30-40 l of cleaning water into the concrete storage tank; keep the concrete storage tank in forward and slow rotation when the vehicle returns;
5. Remember to discharge the sewage in the concrete tank before the next loading;
Automatic cleaning of concrete storage tank and automatic cleaning of concrete storage tank.
1. Unreasonable loading and unloading time parameters: automatic feeding machine can not be installed in the silo, so the industry basically has time control. How to set the time parameter? The setting of loading and unloading time is very simple. In the first use, set a small time first, and then add slowly according to the suction position. When the material reaches the material level and reaches the suction port, subtracting one second is the reasonable time. The discharging time is to ensure that one second is added after discharging. This has two advantages: one is that the material level is too high to damage the filter element; the other is that the material can be put clean every time.
2. Whether the feeding amount at the feeding port of the automatic feeding mixer is reasonable: the correct way is to form a certain air-material mixing ratio between the material at the suction port and the air, and evenly flow into the feeding machine under the driving of the air flow. At this time, we need to design the material gun with air replenishment function. If the material overstocking time is too long, it may be very hard. At this time, we need to install an oscillator on the material gun to break the agglomerated materials.
