Abstract

The invention discloses an air suction type grinder for polygonum cuspidatum. The air suction type grinder for the polygonum cuspidatum comprises a grinder body and an induced draft fan, wherein the discharging end of the grinder body is connected with the induced draft fan through a material storage case, air suction pipes and a cyclone separator; a ventilation door used for adjusting air volume is arranged on one of the air suction pipes; an impeller of the induced draft fan is of a structure with blades in a hollow wedge shape and a backboard in a dish shape; and the shape contour line of the induced draft fan is an involute. By means of the air suction type grinder for the polygonum cuspidatum, sorting of particles and cooling and temperature drop of the material are achieved in the pneumatic transmission process; the return and secondary grinding of the coarse particles are completed in one step, the qualified output of the material is achieved, and meanwhile dust capture is achieved; the timely and smooth discharging of the grinder is guaranteed by an air suction system, the material is prevented from being excessively ground, and electric power is saved; by means of the structure with the blades in the hollow wedge shape and the backboard in a dish shape, the real-time cleaning of dust on the impeller of the induced draft fan and the increase of the strength of the impeller of the draught fan are achieved; the stability is improved, and safety accidents caused by dust accumulation are effectively eradicated; and the application prospect is wide.

Description

technical field [0001] The invention relates to a pulverizer for traditional Chinese medicinal materials, in particular to a pulverizer of knotweed cuspidatum with no dust accumulation in the fan. Background technique [0002] Polygonum cuspidatum is the rhizome of Polygonum cuspidatum, which has the functions of clearing heat and detoxifying, promoting gallbladder and jaundice, dispelling wind and dampness, dissipating blood stasis and relieving pain, relieving cough and reducing phlegm, etc. Symptoms such as excessive phlegm, water and fire burns, injuries from falls, carbuncles and sores are frequently used Chinese herbal medicines. Polygonum cuspidatum 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 shearing of materials, which will generate a large amount of dust and cause the materials to heat up strongly. Cooling and sorting, so that th...
