A method for quickly changing screens and effectively protecting screens, and a vibrating screen

Abstract

The invention provides a method for rapid net replacement and effective screen net protection 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 a net tightening hooping strip. The net rack is located in the screen frame and a residue discharging port is formed in the screen frame. The vibrating screen is characterized in that the net tightening hooping strip is placed on the inner wall of the screen frame, through holes are formed in the position, corresponding to the net tightening hooping strip, of the screen frame, and the ends of the net tightening hooping strip penetrate through the through holes; when the screen net is changed, the screen net is firstly placed on the net rack, the screen frame is then placed above the screen net and falls to the screen net, and after the screen net is folded downwards by the screen frame, the screen net is attached to the outer wall of the net rack; one end of the net tightening hooping strip is connected with a tightening device and the net tightening hooping strip is tightened through operation of the tightening device. According to the vibrating screen, the screen frame and the net tightening hooping strip are of an integrated structure, so that when the screen net is replaced, the screen net only needs to be flatly placed at the upper end of the net rack, the screen frame is then placed above the screen net and falls to the screen net at a time, the screen net can be folded through perpendicular falling operation of the screen frame and attached to the outer wall of the net rack, the screen net does not need to be folded manually, and the vibrating screen is free of the requirement for proficiency of an operator.

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. An important factor affecting the use effect of the vibrating screen is whether the screen can be tightened - the tighter the screen is, the better the vibrating screening effect and the longer the service life. The ...

Problems solved by technology

Although the addition of screens solves the problem of single-layer screens falling, it also brings new problems: when the vibrating motor is working, some materials will inevitably be retained between the two layers of screens, which affects the screening of materials; and Due to the different amplitudes of the two layers of screens, the upper and lower screens will constantly collide during vibration, resulting in vibration friction, and the material friction between the two layers of screens will cause great wear and tear on the screens.

[0013] Due to the above problems, over time, the screen is prone to problems such as broken wires and damage, which will seriously affect the normal production activities of the enterprise

[0014] In the prior art, there has not been an effective method to fully screen the material in the process of moving to the slag outlet, and to quickly replace and tighten the loose and damaged screen while preventing the screen from falling
