Abstract

The invention discloses a panax notoginseng air-drawing type pulverizer, which comprises a pulverizer and an induced draft fan. The damper; the impeller of the induced draft fan has a structure in which the blades are hollow and reversed; the profile of the induced draft fan is an involute. The invention realizes particle sorting and material cooling during the pneumatic conveying process; completes coarse particle return and secondary crushing in one step, realizes qualified output of materials, and also captures dust at the same time; the ventilation system ensures timely and smooth discharge of the pulverizer, avoiding excessive material Crush and save electricity; the blade is hollow and reverse drop-shaped structure, which realizes the real-time cleaning of dust on the impeller of the induced draft fan, increases the strength of the impeller of the fan, enhances the stability and effectively prevents safety accidents caused by dust accumulation, and has broad application prospects.

Description

technical field [0001] The invention relates to a grinder for Chinese herbal medicines, in particular to a panax notoginseng exhaust type grinder in which the fan does not accumulate dust. Background technique [0002] Panax notoginseng, also known as Tianqi, is an Umbelliferae Araliaceae plant, mainly distributed in Yunnan, Guangxi, Jiangxi, Sichuan and other places. Chinese medicinal herb Panax notoginseng uses its root as a medicinal part. It has the effects of dispelling blood stasis and stopping bleeding, reducing swelling and relieving pain. It is mainly used for hemoptysis, hematemesis, epistaxis, blood in the stool, metrorrhagia, traumatic bleeding, chest and abdomen tingling pain, swelling and pain It is a kind of Chinese herbal medicine with high frequency of use, and Panax notoginseng needs to be crushed when it is used as medicine or to extract active ingredients. However, the crushing process is an operation process of strong extrusion, knocking, friction, and ...
