High-effective pharmaceutical crusher

Abstract

The invention discloses a high-effective pharmaceutical crusher, which includes a crushing chamber. The crushing chamber includes a cylinder body and a cylinder cover movably connected thereto. The cylinder body includes an outer cylinder and an inner lining cylinder connected to the inner wall of the outer cylinder. The outer cylinder is connected to the inner lining cylinder through corresponding connection apparatus. Racks are distributed on the inner periphery surface of the inner lining cylinder. A driving apparatus includes a DC driving motor. A coupling is connected between a rotary disk bracket and the DC driving motor. The pharmaceutical crusher has very simple and reasonable structure, is high in work efficiency, is high in relative crushing ratio, has long service life and is low in energy consumption. The pharmaceutical crusher can satisfy diversified production demands on various materials such as biomass granular raw materials. In addition, the pharmaceutical crusher integrates both crushing and sieving, so that the crusher is high in work efficiency and is low in production cost.

Description

Technical field [0001] The invention relates to a pharmaceutical machinery. In particular, it relates to a high-efficiency pharmaceutical pulverizer for pharmacy. Background technique [0002] In the pharmaceutical preparation process, especially the preparation process of Chinese patent medicine, the smaller the powder particles after the pulverization of the pharmaceutical raw materials, the easier the effective ingredients of the pharmaceutical raw materials can be further extracted and utilized. At present, the more commonly used pulverizers mainly include mill type and hammer type pulverizers. The hammer crusher mainly crushes materials by impact. The materials enter the crusher and are crushed by the impact of the high-speed rotating hammers. The crushed materials obtain kinetic energy from the hammers and rush to the baffle and screen in the frame at high speed. Impact and crush each other, the materials smaller than the gap between the screen bars are discharged from th...

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
