Wet-process precise grading device

Abstract

The invention provides a wet-process precise grading device. The wet-process precise grading device comprises an overflowing barrel and a water pump connected with the overflowing barrel through a current equalizer and a flowmeter pipe; the upper portion of the overflowing barrel is cylindrical, the lower portion of the overflowing barrel is in a circular cone shape, the proportion of the height of the overflowing barrel to the diameter of the overflowing barrel is 3-5, and the horizontal initial velocity of materials at an outlet of the current equalizer ranges from 50 mm / s to 80mm / s; an inlet of the water pump is connected with a to-be-graded material slurry pool; and the upper end of the overflowing barrel is connected with a first grading material pool, and the lower end of the overflowing barrel is connected with a second grading material pool. By means of the wet-process precise grading device, according to different material particle setting speeds, the materials are graded, influences of high-speed material feeding on grading are effectively avoided, and the grading accuracy is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of wet classification, and in particular relates to a wet precision classification device. Background technique [0002] At present, the spherical resin products prepared by domestic exchange resin manufacturers have a relatively wide particle size distribution range and poor uniformity, which affects the use effect of spherical resins, so the resins need to be classified. However, the current domestic grading equipment is not effective in grading spherical resins and cannot meet the grading requirements. Contents of the invention [0003] Aiming at the problems existing in the existing grading equipment, the technical problem to be solved by the present invention is to design a wet precision grading device, which can be used to obtain products with relatively narrow particle size distribution. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present...
