The putty powder production line starts the feeding device according to the process batching sequence. First, the rapid feeding device will stop when feeding to the metering batching bin to approach the value (the specific value will be determined during debugging). The fine feeding device continues to feed and gradually approaches the batching amount. Considering the suspension amount, the fine feeding device gradually decelerates and stops in advance (determined during the adjustment of advance amount).
At the same time, the stop valve is closed immediately to stop the possible collapse. The meter will track the feeding amount at any time. After the fine feeding device stops, it will delay Δ T seconds. When it is still, the stable display value of the instrument is the process batching amount of the first material. Then, the second kind of material starts to quickly feed to the metering batching bin Repeat the above procedure until all batching processes are completed. Considering the operating habits and specific requirements of the operators of dry mortar production line, fine feeding can also be done manually.
After the batching work of the metering batching bin is completed, the inclined sealing valve at the bottom of the bin is opened automatically, and the materials in the metering batching bin are discharged into the mixer through the soft coupling and pipeline. After the material is emptied, the instrument returns to zero, and the inclined seal valve closes automatically. Enter the next batching cycle. If the material can not be emptied in time, the inclined sealing valve can not be closed automatically. You can't go to the next program. At this time, the air jet nozzle automatically ejects air from the lower part of the slope to discharge the material. If it is a flexible bin, it will automatically start the massage device to discharge the material.
The inclined seal valve is very important to achieve full sealing. If the valve at the bottom of the bin is not well sealed and there is leakage, it will not only affect the accuracy of batching, but also cause too much dust on site,
