Full-surging type granulating and coating main machine

Abstract

The invention relates to the technical field of fluidized bed type coating machines, and discloses a full-surging type granulating and coating main machine. The main machine comprises a wind power guider, a bowl-shaped body is movably placed at the top of the wind power guider, a round hole is formed in the bottom of the bowl-shaped body, the diameter of the hole is the same as that of the inner cavity of the wind power guider, spring pieces are symmetrically installed at the two ends of the top of the bowl-shaped body, and idler wheels are fixedly installed on the bowl-shaped body through thespring pieces. The bowl-shaped body is movably placed at the top of the wind power guider, and the bowl-shaped body can prevent raw materials from entering a fluidization cavity and a triangular areaat the bottom of the wind power guider, so the qualified rate of the raw materials is ensured; and through the shape setting of the bowl-shaped body, the raw materials pass through an accelerating wall and an ascending wall in sequence when sliding down and then are fluidized by a hot air source, so that the ascending distance of the raw materials is long, the contact time of the raw materials and coating paint is long, and the coating quality is further improved.

Description

technical field [0001] The invention relates to the technical field of a fluidized bed coating machine, in particular to a full-flow granulation coating machine. Background technique [0002] Coating machine is a kind of electromechanical integration equipment for organic film coating of tablets, pills, candies, etc. [0003] see figure 1 , the working process of the existing coating machine is to put the raw material 6 into the bottom of the bottom spray raw material container 1, and spray the hot air source and coating paint through the spray nozzle 4 installed in the inner guide chamber 3 of the wind guide 2, so that the raw material 6 is in the flow The inside of the chemical chamber 5 flips up and down, so that the coating material is evenly sprayed on the outer surface of the raw material 6. After the process is completed, the processed raw material 6 can be unloaded. [0004] It can be seen that the problem existing in the existing fluidized bed coating machine is t...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a full surge type granulation and coating main engine, which has the advantages of increasing the bowl so that the raw materials do not enter the triangular area, the raw material processing quality is good, and the bowl can be lifted to facilitate unloading, which solves the existing flow problem. The triangular area at the bottom of the fluidization chamber and the air guide of the chemical bed coating machine is deep and the flow rate of the airflow is slow, so it is easy to cause the accumulation and blockage of raw materials, resulting in the problem of low processing pass rate of raw materials
