Rotary continuous cleaning equipment for medical drug granulation screen

Abstract

The invention relates to the technical field of medical product granulation accessory devices, in particular to rotary continuous cleaning equipment for a medical drug granulation screen. The equipment is simple in structure and capable of simultaneously adjusting the position of a scraper blade, shortening the time for adjusting the scraper blade during startup and shutdown, reducing the workload of an operator and improving the production efficiency. The equipment comprises an operation table, the granulation screen, a granule guide ring and a fixing ring; supporting legs are mounted at the four corners of the bottom of the operation table; the top of the granulation screen is in a flaring shape, and the granulation screen rotates relative to the operation table; the granule guide ring is fixedly connected with the granulation screen, a plurality of through holes allowing granular drugs to flow out are formed in the bottom of the granule guide ring, the granule guide ring and the granulation screen are coaxial, and a limiting ring for limiting the drugs is fixed to the edge area of the top of the granule guide ring; and the fixing ring is fixedly connected with the operation table through a plurality of supports, a plurality of first long-strip-shaped holes are formed in the fixing ring in a circumferential array at equal intervals, and rails are fixed in the first long-strip-shaped holes.

Description

technical field [0001] The invention relates to the technical field of auxiliary devices for granulating medical products, in particular to a rotary type continuous cleaning equipment for granulating screens of medical products. Background technique [0002] Drugs refer to substances that are used to prevent, treat, and diagnose human diseases, regulate human physiological functions in a purposeful manner, and specify indications or functional indications, usage and dosage, including traditional Chinese medicines, chemical drugs, and biological products; The shape of the medicine is divided into the following tablets, capsules, oral tinctures, oral pills, oral granules, powders, powders, external tinctures, pastes, patches, powders, external paints, suppositories, injections, stimulants, ephedrine Preparations, granular medicines are mostly taken by rotary granulator. [0003] The rotary granulator is a kind of swinging action with a rotating drum. Through the wire sieve, t...

AI Technical Summary

Problems solved by technology

[0004] When the existing rotary granulator is granulating, many scrapers are installed on the outside of the granulating screen, which are close to the outer wall of the granulating screen. When the medicine is extruded along the gap of the rotating granulating screen, the position is fixed The scraper scrapes off the drug, and then exports it to complete the granulation. The above process found the following disadvantages: the number of scrapers is large, and the scrapers can be adjusted along the radial direction of the granulation screen to adjust the distance between them and the granulation screen. However, these scrapers are all adjusted manually, which will delay a lot of time every time they start and stop, and increase the workload. It is also very likely that a scraper will not be adjusted, resulting in improper granulation Smooth, affecting production efficiency
