Overlapping high-frequency fine screen

Abstract

The invention relates to an overlapping high-frequency fine screen, which is provided with a framework, a plurality of inclined screening units are arranged from the top down on the framework, a distributor is arranged at one end of the upper part of each screening unit, each distributor is connected to a divider, a vibration exciter is mounted on the framework over the uppermost screening unit, shock-absorbing springs are mounted on the bottom of the lowermost screening unit, screen frames of all the screening units are arranged in parallel from the top down, and moreover, the inclination angle of each screen frame inclined downward from the horizon is 20 to 35 degrees; an oversize discharge plate is provided with at least one longitudinal V-shaped separation baffle; undersize-receiving buckets are mounted just under corresponding screen surfaces, and the section of each undersize-receiving bucket is shaped like a circular arc or a trapezium. The overlapping high-frequency fine screen has a simple and compact structure, and does not occupy an extra space, the manufacturing cost is greatly reduced, the overall dimensions are small, the occupied area and the occupied space are small, moreover, the installation cost is little, the length of each layer of screen frame is not limited, and large scale can be easily achieved.

Description

technical field [0001] The invention relates to the technical field of screening mechanical equipment, in particular to a stacked high-frequency fine screen. Background technique [0002] In metallurgy, building materials, chemical industry and other production fields, fine material screening operations are common. In fine material screening, the processing capacity per unit screening area is low, and the required screening area is large. Therefore, stacked high-frequency screening is generally used in large-scale production processes. The fine sieve performs the fine screening operation. [0003] At present, the laminated high-frequency fine screens produced at home and abroad are all Derek overlapping high-frequency fine sieves or their improved products. The way to connect together, realize the collection of under-screen materials independently screened into the same collection tank, and the collection of over-screen materials into the same collection bucket; the stacked...

AI Technical Summary

Problems solved by technology

[0005] 1. The feeding point of each screen surface is far away, the feeding pipeline is long, and the slurry distributor and feeding should be installed and fixed on another platform besides the main machine;

[0006] 2. The size of the equipment is huge, and the floor area and space are large; the installation and use costs are high;

[0007] 3. The length of each screen frame should not exceed 2m, otherwise it will cause inconvenience in operation and maintenance; this greatly limits its difficulty in realizing large-scale equipment. Developed to a screening area of ​​about 10 square meters, the work efficiency is low, and it is difficult to meet the needs of mass production
