Wet mixing granulator sprayed with Teflon

Abstract

The invention discloses a wet mixing granulator sprayed with Teflon. The granulator comprises a tank body, a granulating knife is arranged on the tank body; a material delivery hole and a feeding holeare formed in the tank body; the granulating knife comprises a driving motor, a coupler and a knife body; the coupler is connected with the tank body through a connecting seat; a rotating shaft sealing cover is arranged between the connecting seat and the coupler; the coupling is further sleeved with a sealing cover; and the connecting seat is arranged outside the sealing cover in a sleeving modeand fixedly connected with the sealing cover. The sealing cover, the connecting seat and the rotating shaft sealing cover are combined to form a sealing cavity; an air inlet channel and an air outletchannel are formed in the connecting seat and / or the sealing cover, a positioning frame is arranged on the material delivery hole side in the tank body, a driving cylinder is arranged on the positioning frame, a baffle is connected to the output shaft of the driving cylinder, a plurality of purging nozzles are arranged on the positioning frame, and a filter barrel is further arranged on the feeding hole. The granulator has a good sealing property, the overall using effect is improved, meanwhile, materials in the material delivery hole can be effectively cleaned, and the service life of the whole granulator is prolonged.

Description

technical field [0001] The invention relates to the technical field of wet granulators, in particular to a wet mixing granulator sprayed with Teflon. Background technique [0002] The wet mixing granulator sprayed with Teflon has multiple functions such as mixing and granulating. After the powder material is put into the mixing container, under the action of the stirring paddle and the cutter, the material is cut and stirred into a flow state, thus obtaining Mix well. At present, the wet mixing granulator sprayed with Teflon is widely used in the pharmaceutical, food and chemical industries. However, with the improvement of drug preparation requirements, the airtightness requirements of the equipment are getting higher and higher. Since the knife body needs to be driven by an external motor, through a series of transmission structures, it is easy to have airtightness between the knife body and the granulator barrel.

Problems solved by technology

However, with the improvement of drug preparation requirements, the airtightness requirements of the equipment are getting higher and higher. Since the knife body needs to be driven by an external motor, through a series of transmission structures, it is easy to have airtightness between the knife body and the granulator barrel. In the case of poor performance, it affects the airtightness of the overall structure, allowing external dirt to enter, which is not conducive to the production requirements of powder particles with high cleanliness requirements. At the same time, since the cutter body is driven by the motor, it is also necessary to prevent powder particles from entering the granulator. The transmission connection will cause damage to the transmission parts. Similarly, at the position of the feeding port, the prepared particles will be sent out from the feeding port, but some powder particles prepared will be toxic and corrosive, and these powder particles will remain at the feeding port. It is not conducive to the processing and production of subsequent products, but due to the toxicity of the particles, it is not convenient for the operator to clean up. At the same time, the feeding port is usually equipped with a mechanical structure to control the opening and closing. Some powder particles may also fall on the position of the transmission structure, and the corrosive The powder particles will erode the transmission structure and affect the service life of the overall structure
