Abstract

The invention discloses graded pearl screening equipment and a using method thereof, and belongs to the field of valve corrosion prevention. The graded pearl screening equipment comprises an operationconsole; the upper portion of the operation console is provided with a vibration feeder, the upper end of the operation console is provided with a grading groove, and the left side wall of the operation console is provided with a round channel; the inner bottom surface of the grading groove is provided with a plurality of uniformly-distributed discharging groves, and the opening diameter of uppergroove openings of the multiple discharging grooves is gradually increased in the direction away from the round channel; the interior of the operation console is provided with a collecting cavity, and the collecting cavity is located on the lower sides of the discharging grooves and communicates with the discharging grooves; the interior of the grading groove is provided with a grading transmission mechanism; and the grading transmission mechanism comprises a driving wheel and a driven wheel, and the driven wheel is located on the left side of the driving wheel. According to the graded pearlscreening equipment and the using method thereof, it can be achieved that one-time multiple-grade screening can be conducted on pearls, the pearls different in size are subjected to multi-grade fine classification in one step, and automatic screening equipment high in efficiency and low in cost is provided for the pearl screening process.

Description

technical field [0001] The invention relates to the field of valve anticorrosion, and more specifically, relates to a graded pearl screening device and a method for using the same. Background technique [0002] Pearl is an ancient organic gemstone, mainly produced in the molluscs of pearl shellfish and mother-of-pearl shellfish; and the calcium carbonate-containing mineral (aragonite) beads produced by endocrine action are composed of a large number of tiny aragonite crystals It is a collection; it is rich in variety, in different shapes and colorful; according to the research of geology and archaeology, there were already pearls on the earth 200 million years ago; in the international gem circle, pearls are also listed as June Lucky stone for birthday, commemorative stone for 13th and 30th wedding anniversary. Pearls with magnificent colors and elegant temperament symbolize health, purity, wealth and happiness, and have been loved by people since ancient times. [0003] T...
