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.
Practice has proved that this scheme is not feasible

Embodiment 1

[0026] like figure 1 , 2 As shown in , 3, a vibrating screen includes a screen frame 1, a screen cloth 2 and a support body 3, the support body 3 is vertically arranged on the screen frame 1, and the support body 3 is connected with the screen cloth 2.

[0027] The upper end of the support body 3 and the screen cloth 2 are connected by magnetic components. The upper end of the support body 3 is fixed with a magnet 31. A magnet 32 ​​is placed at a position corresponding to the magnet 31 above the screen cloth 2. The magnet 31 is opposite to the magnet 32 ​​with different poles. The magnet 32 ​​clamps the screen cloth 2 by magnetic force. In addition, the magnetic component can also select the combination of magnet 31 and iron sheet 35, magnet 31 is fixed on the upper end of support body 3, and iron sheet 35 is placed on the corresponding position on the screen 2; or iron sheet 35 is fixed on the upper end of support body 3, and the magnet 31 is placed at the corresponding pos...

Embodiment 2

[0029] like Figure 4 As shown, the difference between the present embodiment and the first embodiment is that an iron core 34 wound with an electromagnetic coil 33 is arranged on the upper end of the support body 3 , and an iron sheet 35 is placed on the screen 2 corresponding to the position of the iron core 34 . After the electromagnetic coil 33 is energized, the iron core 34 will generate a magnetic field and attract the iron sheet 35, thereby achieving the purpose of clamping the screen 2 .

Embodiment 3

[0031] The difference between this embodiment and Embodiment 1 is that the upper end of the support body 3 and the screen mesh 2 are connected by glue, and the upper end of the support body 3 is bonded to the screen mesh 2 with an adhesive, and the fineness of the screen mesh 2 The rope will be coated with adhesive, so that the tensile strength of the string increases, prolonging the service life of the screen 2 .

Abstract

A vibrating screen comprises a screen frame and a screen mesh, and is characterized in that a supporter is fixed on the screen frame and connected with the screen mesh. The vibrating screen has the advantages that owning to the supporter connected under the screen mesh, the screen mesh is supported by the supporter, the middle of the screen mesh cannot fall and damage to the screen mesh is avoided while vibrating screening effect is enhanced; as the supporter is connected with the screen mesh integrally, the supporter and the screen mesh have the same vibration amplitude during operation of a vibrating motor, a supporting rod is used as a vibration source, damage to the screen mesh due to vibration of the supporter is avoided, and the service life of the screen mesh is prolonged; since the supporter is connected with the screen mesh by a magnetic component, the screen mesh is clamped by magnetic force, and damage to the screen mesh due to boring is avoided; accordingly, damages to the screen mesh of an existing vibrating screen are avoided, people do not need to customize the special screen mesh and only need to modify on the basis of the existing vibrating screen simply, modification cost is low, and adaptability is high.

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] Vibrating screens are widely used in building pottery factories and other enterprises to separate materials. Commonly used vibrating screens include structural components such as screen frames, screen meshes, 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., and the screen is mostly placed horizontally or with a certain angle of inclination. When materials are placed on the screen, the screen will fall under the influence of gravity. The impact of the screen mesh drop is obvious. Due to the screen mesh drop, each filament on the s...
