A superfine natural pearl powder screening device for convenient discharge

Abstract

The invention discloses a superfine natural pearl powder screening device with a convenient discharging function. The superfine natural pearl powder screening device comprises a base and a screening tank, wherein the screening tank is arranged on the base; a blocking plate is arranged on the lower side of a feeding hopper; a screening slot is rotationally mounted on a swinging shaft; a driving motor is fixedly mounted on a bracket; and a left cam and a right cam are mounted on output shafts positioned at the left and right ends of the driving motor in an interference fit manner, and correspondingly get in contact with ejector blocks positioned at the lower ends of a left ejector rod and a right ejector rod. Through the arrangement of an intermittent discharging disc, the intermittent quantitative dropping operation can be achieved when pearl powder drops into the screening slot for being screened, thereby preventing the circumstance that too much pearl powder drops at a time, the screening pressure is excessive, and then a screening mesh is blocked by the pearl powder; through the swinging screening action of the screening slot, the pearl powder screening operation on the screeningmesh inside the screening tank can be accelerated; and through the left and right inclination of the screening tank, the pearl powder discharging speed can be improved, the residue of the pearl powder inside the screening tank can be avoided, and then the relatively simple cleaning operation can be achieved.

Description

technical field [0001] The invention relates to a sieving device, in particular to a superfine natural pearl powder sieving device for convenient discharge. Background technique [0002] Natural pearl powder: It is produced by physical methods (such as ball milling, jet crushing and physical method ultrafine powder technology), and its characteristic is that it does not add any other substances, does not destroy any substances, and maintains all the nutrients of pearls. Pearl powder can be divided into three categories according to its particle diameter: 1. Ordinary pearl powder: the particle size is more than 200 mesh, which can meet the basic requirements of the country. [0003] 2. Ultrafine pearl powder: fineness above 1000 mesh (or particle size below 15 microns), 3. Nano pearl powder: fineness above 150,000 mesh (or below 100 nanometers), the smaller the particle size of pearl powder, the more difficult the processing technology The higher the price, the higher the pr...

AI Technical Summary

Problems solved by technology

[0004] After the pearl powder is ground, it is necessary to sieve the pearl powder to ensure the quality of the pearl powder. The existing pearl powder is not efficient in screening, and at the same time, it is easy to block the holes of the screen and it is difficult to discharge.
