Granulation knife sealing structure of wet mixing granulator

Abstract

The invention discloses a granulation cutter sealing structure of a wet mixing granulator. A granulation transmission device comprises a granulation cutter transmission shaft. The granulation cutter sealing structure comprises a granulation cutter flange seat fixedly connected to a material cylinder, a sealing piece, a friction sleeve and a sealing cover, wherein a flange hole is formed in the granulation cutter flange seat; the granulation cutter transmission shaft penetrates through the flange hole of the granulation cutter flange seat to fixedly sleeve an output shaft of a motor; the outer surface of the granulation cutter transmission shaft in the flange hole of the granulation cutter flange seat is covered with the friction sleeve sleeving the granulation cutter transmission shaft; the sealing cover covers the friction sleeve and seals the top end face of the granulation cutter flange seat in a covering manner in the material cylinder; the friction sleeve and the inner wall of the flange hole of the granulation cutter flange seat are sealed through the sealing piece; an annular cavity consisting of the sealing piece, the outer wall of the friction sleeve, the inner wall of the flange hole of the granulation cutter flange seat and the sealing cover is formed in the flange hole of the granulation cutter flange seat. Therefore, no dead corner is reserved on the structure, and an on-side cleaning function can be realized; the cleaning work is simple and time-saving, and no residue can be retained during cleaning.

Description

technical field [0001] The invention relates to a sealing mechanism of a wet mixing granulator, in particular to a sealing structure of a granulating knife of a wet mixing granulator. Background technique [0002] The wet mixing granulator is a special equipment for wet mixing and granulating the powder, starch and binder in the tablet life of the pharmaceutical industry. It is also suitable for mixing and granulating powdery materials in food and chemical industry. Its structure generally includes a base, a material tank, a stirring mechanism, and a granulating mechanism. The stirring mechanism is composed of a stirring transmission device and a stirring paddle. The granulating mechanism is composed of a granulating knife rotating device and a granulating knife. The granulating knife is installed on the material. On the side wall of the cylinder, there must be a granulation knife sealing mechanism between the granulation knife transmission device and the material cylinder ...

AI Technical Summary

Problems solved by technology

Furthermore, the seal is an easy-to-wear part. After the wear, the motor behind the material cylinder must be removed for maintenance and replacement. Since the motor is fixed on the base, its removal is not only inconvenient but also time-consuming, and the entire maintenance work is cumbersome. , and the frequent disassembly and installation of the motor has a great impact on the service life of the motor
