Method for improving working condition and effectively protecting screen and vibrating screen

Abstract

The invention provides a method for improving a working condition and effectively protecting a screen and a vibrating screen, and belongs to the technical field of material screening. The vibrating screen comprises a screen frame, a net rack, a screen net and net tightening strakes, and the net rack is placed in the screen frame. The vibrating screen is characterized in that the net tightening strakes are placed on the inner wall of the screen frame, through holes are formed in the positions, corresponding to the net tightening strakes, in the screen frame, and the ends of the net tightening strakes penetrate out from the through holes; when the screen net is replaced, the screen net is first flatly placed on the net rack, then the screen frame is placed on the screen net and falls down, and after the screen net is folded downwards from the screen frame, the screen net is applied and attached to the outer wall of the net rack; the ends of the net tightening strakes are connected with a tightening device, and the net tightening strakes are tightened by operating the tightening device. According to the method for improving the working condition and effectively protecting the screen and the vibrating screen, due to the fact that the screen frame and the net tightening strakes are of an integral structure, when the screen net is replaced, the screen net only needs to be flatly placed at the upper end of the net rack, then the screen frame is placed on the screen net to fall down at one time, the screen net can be bent and then applied and attached to the outer wall of the net rack through vertical falling of the screen frame, manual bending of the screen net is of no need, and the request for the skill proficiency of operators does not exist.

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

These incompletely screened materials carry a lot of moisture and fines, causing great waste

When these materials are still on the screen, because they carry a lot of water and fine materials, they have a relatively large mass, which will cause a certain burden on the screen.

Over time, the screen will loosen easily, and the working condition of the screen will become worse, which will lead to more serious falling and collapse of the screen, which will seriously affect the normal production activities of the enterprise

[0016] In the industry, there has been no good solution for quickly replacing the screen and effectively tightening it, as well as improving the working condition of the screen and prolonging its life.
