Method for rapidly replacing screen and flexibly distributing material and vibrating screen

Abstract

A method for rapidly replacing a screen and flexibly distributing material and a vibrating screen belong to the technical field of material screening. The vibrating screen comprises a screen frame, a screen support, the screen and screen-tightening hoop strips, the screen support is located in the screen frame, the vibrating screen is characterized in that the screen-tightening hoop strips are placed on the internal wall of the screen frame, the screen frame is provided with through holes at positions corresponding to the screen-tightening hoop strips, and the ends of the screen-tightening hoop strips pass through the through holes. During screen replacement, a screen is first placed flat on the screen support, the screen frame is then placed on the screen and drops, and after being downwardly bent by the screen frame, the screen clings to the external wall of the screen support; the ends of the screen-tightening hoop strips are connected with tighteners and tightened by operating the tighteners. Because the screen frame is integrated with the screen-tightening hoop strips, during screen replacement, the screen is placed flat on the top end of the screen support, the screen frame is then placed on the screen and drops in one step, the screen can cling to the external wall of the screen support after being bent by the vertically dropping screen frame, consequently, the screen does not need to be bent manually, and the skill proficiency of an operator is not required.

Description

technical field [0001] The invention belongs to the technical field of material screening, and in particular relates to a vibrating screen. Background technique [0002] Enterprises widely use vibrating screens to sort materials. Commonly used vibrating screens include structural components such as screen frames, grid frames, screen meshes, stretching hoops, springs connected to the screen frames, and vibration motors. The screen is vibrated by starting the vibrating motor, so that the small particles pass through the screen and leak down, and the large particles are blocked on the screen. The screen used in the vibrating screen is generally woven with metal wire, nylon wire, etc. The screen is a vulnerable part and needs to be replaced after a period of use. The important factors affecting the use effect of the vibrating screen are whether the screen can be tightened and whether the material can be evenly distributed - the tighter the screen, the better the vibrating scre...

AI Technical Summary

Problems solved by technology

[0012] (1) Due to the fast flow rate of the slurry, when the slurry is poured from a certain height to the screen, it will have a greater impact on the screen, which is easy to cause damage to the screen and affect the service life of the screen.

[0013] (2) When the slurry is poured on the screen, the speed is fast, so that the screen has no time to screen the slurry, so more and more slurry will be poured on the screen, and the pressure generated by too much slurry will also cause Damage to the screen and increase the burden on the vibrating motor, reducing the service life of the vibrating screen

[0014] (3) The slurry falls at a faster speed, so it splashes around after falling on the screen, which pollutes the environment of the workplace and also causes a waste of slurry

In the industry, there has been no good solution for quick replacement of the screen, high-quality effective tensioning of the screen, and uniform distribution of materials to reduce the impact of falling.
