The working principle of vacuum material suction is that a certain negative pressure is formed in a hopper cavity to suck materials into the hopper. The working process is as follows: when the material shortage exists in the hopper, a contact switch for detecting the material sends a signal to the suction machine, the motor of the suction machine starts to operate to vacuumize, the suction machine starts to suck the material when the closed system reaches a certain vacuum degree, the raw material is sucked into the hopper cavity and isolated below the filter screen, after the material is sucked for a certain time, the motor stops, and the raw material falls into the hopper from the lower part of the filter screen to complete the discharging link. After a certain preparation time, the next cycle is carried out. When the hopper is full of material, the contact switch for detecting the material level gives out a signal, and the material sucking action is terminated.
In the using process of the suction machine, a large amount of dust can be generated due to the carrying of the granules or the friction between the granules and the inner wall of the suction pipeline, and the leakage phenomenon still exists even though the dust is filtered by an air filter after passing through a filter screen, so that the surrounding environment is polluted. Meanwhile, the filter screen needs good air permeability to provide large suction, so that the filter screen with a large number of meshes cannot be adopted, and the filter screen for the powdery and liquid raw materials with small particles cannot filter the raw materials, and the feeding mode can only be applied to the transmission of the large-particle raw materials.
