A swinging ultrafine natural pearl powder screening device

Abstract

The invention discloses a swing type superfine natural pearl powder screening device. The swing type superfine natural pearl powder screening device comprises a base, a screening box and a swing device. An output shaft of a rotating motor is forward and is provided with interval discharge plates in a manner of interference fit, a swing shaft is rotationally provided with a screening tank, and theswing device is further arranged at the bottom of the screening box. By arranging the interval discharge plates, interval quantitative discharge is realized, pearl powder falls into the screening tankto be screened, and the situation that the mesh screen is blocked by the pearl powder due to too high screening pressure caused by excessive one-time discharge is prevented; by achieving swing type screening of the screening tank, the speed of screening of the pearl powder on the mesh screen inside the screening box is increased, meanwhile the flow rate of the pearl powder on the mesh screen is improved, and the occurrence of hole blockage caused by the pearl powder is prevented; and through left-right tilting of the screening box, the discharge speed of the pearl powder is increased, the situation of pearl powder residue inside the screening box is avoided, and thus cleaning is relatively simple.

Description

technical field [0001] The invention relates to a screening device, in particular to a swinging type superfine natural pearl powder screening device. 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 price, bu...

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. When the existing pearl powder is screened, it is easy to block the holes of the screen and it is difficult to discharge.
