Description

Auxiliary blanking mechanism for preventing powder from hardening and being overhead Technical Field The utility model relates to the field of raw liquid batching of filters, in particular to an auxiliary blanking mechanism for preventing powder from hardening and overhead. Background In the batching operation of the filter raw material tank, powder is thrown into the tank by an auxiliary blanking mechanism and stirred, and the mechanism mainly comprises a hopper and a feeding assembly. Among them, the auger is a common feeding member (one of feeding members) and is problematic in conveying fibrous powder such as wood fiber. The wood fibers have a unique fibrous structure, when the wood fibers enter the hopper and are continuously extruded and pushed by the spiral blades of the auger, the fibers are mutually wound and tightly meshed due to high friction, and along with continuous operation of the auger, the extrusion effect is gradually enhanced, so that powder at the hopper position above the auger is compacted into a solid with extremely high density. Due to the dual effects of the gravity action of the materials in the hopper and the mechanical extrusion of the auger, the entity forms a plate junction layer above the auger gradually, a dead zone is formed below the plate junction layer due to the conveying of the auger, the upper powder cannot fall down smoothly and be supplemented due to the support of the plate junction layer, and finally, the overhead phenomenon occurs in the hopper.
