Efficient pharmaceutical pulverizer

Abstract

The invention discloses an efficient pharmaceutical pulverizer. The efficient pharmaceutical pulverizer comprises a pulverization chamber, wherein the pulverization chamber comprises a cylinder body and a cylinder cover which is movably connected with the cylinder body; the cylinder body comprises an outer cylinder and a lining cylinder which is connected with the inner wall of the outer cylinder; the lining cylinder is connected through a corresponding connection device; racks are distributed on the inner circumferential surface of the lining cylinder; a driving device comprises a DC driving motor; and a coupling is connected between a turntable frame and the DC driving motor. The efficient pharmaceutical pulverizer is extremely simple and reasonable in structure, high in working efficiency, high in relative pulverization ratio, long in service life and low in energy consumption, is capable of satisfying the diversified production requirements of a plurality of materials which comprise biomass particle raw materials, and integrates pulverizing and screening to ensure that the working efficiency is high and the production cost is low.

Description

technical field [0001] The invention relates to a pharmaceutical machine. In particular, it relates to a high-efficiency pharmaceutical pulverizer for pharmaceuticals. Background technique [0002] In the process of drug preparation, especially in the process of preparing Chinese patent medicines, the smaller the powder particles after the drug raw materials are crushed, the easier the active ingredients of the drug raw materials can be further extracted and utilized. The more commonly used pulverizers mainly include grinding mills and hammer mills. The hammer mill mainly relies on the impact to crush the material. The material enters the crusher and is crushed by the impact of the high-speed rotating hammer. Mutual impact and crushing, the materials smaller than the gap between the screen bars are discharged from the gap, and some larger materials are crushed by the impact and extrusion of the hammer on the screen bar again, and the material is squeezed out from the gap b...

AI Technical Summary

Problems solved by technology

[0003] However, most of the existing hammer mills used in pharmaceuticals have unreasonable settings and matching structures for hammers, screens, and crushing chambers, and their functions are relatively single, which cannot meet the diverse production requirements of biomass particle raw materials, and has a short service life. The crushed material cannot be quickly discharged from the crushing chamber in time, resulting in a relatively low crushing efficiency

[0004] However, the existing preparation method of drug powder is generally to first pulverize with a pulverizer, and then sieve with a sieving machine, which requires the use of two different equipment, so the production efficiency is not high
