Self-cleaning pulverizer for processing high-quality heparin sodium

Abstract

The invention relates to the technical field of medicine material pulverizing, and discloses a self-cleaning pulverizer for processing high-quality heparin sodium. The self-cleaning pulverizer comprises a feeding funnel, a pulverizing mechanism and a main discharge port; the pulverizer mechanism is in communication with the feeding funnel, and the main discharge port is in communication with a discharge port of the pulverizing mechanism; a screen is detachably fixed on the inner wall of a cavity of the pulverizing mechanism, an air injection device is further arranged on the inner wall of thecavity of the pulverizing mechanism and comprises an air inlet pipeline and an exhaust piece with a hollow interior; the exhaust piece is in communication with the air inlet pipeline; the air inlet pipeline penetrates through the cavity and is fixed to the cavity, the exhaust piece is located between the screen and the inner wall of the cavity, a plurality of exhaust holes are evenly formed in theexhaust piece, and an air valve is arranged on the air inlet pipeline on the outer side of the cavity. Compared with the prior art, the air injection device is additionally arranged on the inner wallof the cavity of the pulverizing mechanism, inert gas is injected after the pulverizer is shut down, residual materials on the inner wall of the cavity and the screen are blown down through gas flowing, the later-period manual cleaning time is saved, and the problems of the high-quality heparin sodium pollution and medicine material waste caused by knocking the cavity of the pulverizer can be prevented.

Description

technical field [0001] The invention relates to the technical field of crushing pharmaceutical materials, in particular to a self-cleaning grinder for processing high-quality heparin sodium. Background technique [0002] During the production and processing of high-quality heparin sodium, it is necessary to pulverize the prepared blocky large-size solid raw materials to the required size through a pulverizer. This requires a shredder to operate. Existing pulverizers use hammering, grinding, etc. to pulverize materials. During the pulverization process, the materials will have a certain viscosity after being heated, and the internal structure of the inner wall of the cavity, the screen, the turntable, etc. is irregular. The ground material is extremely easy to adhere to the screen and the inner wall of the crushing mechanism cavity, while the high-quality heparin sodium pharmaceutical materials are more expensive and cannot be wasted. Manual cleaning, but the medicine canno...

Problems solved by technology

Existing pulverizers use hammering, grinding, etc. to pulverize materials. During the pulverization process, the materials will have a certain viscosity after being heated, and the internal structure of the inner wall of the cavity, the screen, the turntable, etc. is irregular. The ground material is extremely easy to adhere to the screen and the inner wall of the crushing mechanism cavity, while the high-quality heparin sodium pharmaceutical materials are more expensive and cannot be wasted. Manual cleaning, but the medicine cannot be manually touched during the grinding process, which is easy to contaminate the medicine; the common solution is to vibrate the outer wall of the pulverizer to make the material vibrate and fall into the discharge port, but this method is easy to Other impurities in the inner wall of the pulverizer knocked down into the material, resulting in the pollution of high-quality heparin sodium medicine, so there is an urgent need for a cleaning device that can easily clean the residual materials on the inner cavity and the screen without causing pollution
