Crushing device for biological medical material machining

Abstract

The invention discloses a crushing device for biological medical material preparation. The device comprises an outer box body; a crushing cavity is formed in the outer box body, and a feeding port isformed in the upper portion of the crushing cavity; an upper sieve plate is arranged below the feeding port, fixing plates are fixedly mounted on the left side and the right side of the upper sieve plate, and the fixing plates are fixedly mounted on the front end wall and the rear end wall of the crushing cavity; a T-shaped sliding groove is formed in the lower end wall of the crushing cavity, andcrushing assemblies are symmetrically arranged in the crushing cavity left and right; and a falling cavity is formed below the upper sieve plate, a grinding cavity is formed below the falling cavity,and a circulating inlet is formed in the left upper part of the grinding cavity. Through adding the crushing assemblies, the material quality is higher, and a plurality of grinding crushing wheels are arranged, so that the crushing and grinding effect of raw materials is greatly improved; the action of the upper sieve plate effectively avoids blockage at the blanking channel, and the action of the lower sieve plate can enable the machined non-qualified material to be machined again until qualified; and the device is high in machining quality and high in practicability.

Description

technical field [0001] The invention relates to the field of biomedical materials, in particular to a crushing device for processing biomedical materials. Background technique [0002] Biomedical materials, also known as biomaterials, are a class of high-tech new materials used for diagnosis, treatment, repair or replacement of human tissues or organs or to enhance their functions, which can be natural or synthetic, or their complex. Biomedical materials are not drugs, and their effects do not need to be realized through pharmacological, immunological or metabolic means. They cannot be replaced by drugs and are necessary to ensure human health, but they can be combined with them to promote the realization of their functions. According to international practice, its management belongs to the category of medical devices, accounting for >40% of the medical device market. [0003] According to the composition and structure of materials, biomedical materials can be divided i...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a crushing device for processing biomedical materials, which overcomes the tendency of material accumulation on the filter plate after crushing, resulting in blockage of the filter plate, incomplete crushing of processed materials, and poor crushing effect. Not good and other problems, so that the quality of biomedical materials processed is higher
