Screening device for separating corncobs from pearls

Abstract

The invention discloses a screening device for separating corncobs from pearls. The screening device comprises a base, and a discharging mechanism, a vibration conveying mechanism and a reciprocatingmechanism are installed on the base. An electrostatic adsorption system is additionally arranged on the reciprocating mechanism, the electrostatic adsorption system comprises an electrostatic adsorption surface moving along with the transmission nut seat, and the electrostatic adsorption surface is composed of an electrode and an insulating sheath covering the outer surface of the electrode. The electrodes are supplied with current by a power supply device, the power supply device is controlled by an operating switch, and the electrostatic adsorption surface adsorbs corncobs on the vibration bed body and moves to the position above the material return box along with the transmission nut base, so that the corncobs fall into the material return box, pearls fall into the collecting box from the vibration bed body, and the problems which cannot be solved through traditional mesh screen screening when the grain sizes of the corncobs and the pearls are the same are solved.

Description

technical field [0001] The invention relates to the field of pearl screening equipment, in particular to a screening device for separating corncobs and pearls. Background technique [0002] The last process in the pearl optimization process is the polishing process, which reflects the level of pearl processing technology. The polishing result directly affects the quality and market price of pearls. Polishing refers to the processing of pearls after bleaching to increase the luster of pearls. Technology, that is, to improve the intensity of reflected light on the surface of the pearl and the clarity of the image, because the polishing material can grind the uneven surface of the pearl to make the surface of the pearl smoother. The polishing material uses corncobs with a particle size of 2 to 3mm. It is recorded in CN201010238312.8 that corncob is a bright substance (wax) attached to a polishing carrier (corncob), and the quality of corncob is very light. When using it, cornco...

[0002] The last process in the pearl optimization process is the polishing process, which reflects the level of pearl processing technology. The polishing result directly affects the quality and market price of pearls. Polishing refers to the processing of pearls after bleaching to increase the luster of pearls. Technology, that is, to improve the intensity of reflected light on the surface of the pearl and the clarity of the image, because the polishing material can grind the uneven surface of the pearl to make the surface of the pearl smoother. The polishing material uses corncobs with a particle size of 2 to 3mm. It is recorded in CN201010238312.8 that corncob is a bright substance (wax) attached to a polishing carrier (corncob), and the quality of corncob is very light. When using it, corncobs and pearls need to be placed in a polishing bucket for polishing. Polishing, due to the heating caused by friction, part of the bright material leaves the corncob to fill in the tiny pores and surface defects on the pearl surface, so that the light keeps continuous when it propagates on the pearl surface, thereby increasing the reflective intensity of the pearl surface and greatly improving the appearance of the pearl. , when the particle size of the pearls to be polished is 2-3mm, the pearl particle size and the corncob particle size are the same, and the corncob can be used for many times, and the traditional mesh method will not work. It is impossible to screen through simple physical vibration, and the corncob and pearl cannot be separated by brushing at all. Manual screening is troublesome. The existing market has not solved this problem, so we carry out the comparison with pearls based on the characteristics of the small quality of corncob. The separation of corncobs and pearls is designed a screening device
