Vibration sieve and method for adopting thick glue to compress and tighten screen

Abstract

The invention belongs to the technical field of material screening, and particularly relates to a vibration sieve and a method for adopting thick glue to compress and tighten a screen. A sieve frame,a screen, a screen frame and a vibration body are included. Locking discs are arranged on the edge of the sieve frame and the edge of the vibration body. The screen is laid on the screen frame, and the edge of the screen is tightly pressed below the sieve frame locking disc. The sieve frame, the screen frame, the screen and the vibration body are fixed together at the outer portion through fasteners. The vibration sieve and the method for adopting the thick glue to compress and tighten the screen are characterized in that elastic pieces with upper and lower elasticity are further included, andthe elastic pieces are arranged below the part, above the vibration body locking disc, of the screen. According to the vibration sieve and the method, the screen can be tightened directly through locking of the fasteners at the outer portion, and operation is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of material screening, and in particular relates to a vibrating screen and a method for compressing and tightening a mesh with thick glue. Background technique [0002] Enterprises widely use vibrating screens to sort materials. Commonly used vibrating screens include screen frames, mesh frames, vibrating bodies, screen meshes, mesh hoops, vibrating springs connected to the vibrating bodies, vibrating motors and other structural components. By starting the vibrating motor To drive the vibrating body, the screen mesh and the screen frame to vibrate up and down together, so that the small particle material leaks through the screen mesh, and the large particle material is blocked on the screen mesh. The screen used in the vibrating screen is generally made of metal wire, nylon wire, etc., and the screen is easily loosened by the falling effect of the material during the vibration process. The important factor ...

Problems solved by technology

[0008] In the above process of tightening the screen, the screen is manually bent and leveled. However, the screen usually has a certain degree of elasticity. When manually bending, two people need to cooperate tacitly to bend it. Otherwise, the screen is easy to bend during the bending process. Tilting, which requires certain skills of the operator

In addition, when screening some special materials (such as cement), the material is highly viscous and often sticks to the inner wall of the screen frame. It is time-consuming and laborious to tighten the screen for screening such materials. Therefore, when using , if the screen is loose, generally the screen will not be tightened again, and the screen can only be replaced after it is broken

The consequence of this is that the vibration effect of the vibrating screen is not good, and the vibration time is prolonged, which further affects the service life of the entire vibrating screen and vibrating motor.

In the industry, how to quickly, conveniently and effectively tighten the screen has not been a good solution
