The vacuum conveyor uses a vacuum pump to pump air, so that the inlet of the suction nozzle and the entire negative pressure state, the powder and granules are sucked into the nozzle along with the outside air, forming a tube to reach the hopper, and the gas and material are separated in the hopper. The separated material enters and discharges by continuously opening and closing the pneumatic reversing valve, and the pneumatic reversing valve is controlled by the control center.
During this process, the materials are into this weighing hopper, and then weighs the whole. In the process of stably conveying the material by the quantitative screw doing below, the speed sensor and the load cell will accurately provide the running speed of the screw and the instantaneous load of the material. These two signals can be received and processed by the programmable controller PLC. According to the comparison between the measured value and the set value, the corresponding adjustment signal is output, and the screw speed is adjusted by the frequency converter to change the conveying amount of the material, so as to accurately complete the weighing measurement of the material and the control of the material quantitative feeding. In the whole working process, it can automatically adjust the flow according to the set Feeding amount according to the predetermined program to make it equal to the set value. Continuous delivery at a constant feed rate.
