Description

Technical Field

[0001] The utility model belongs to the technical field related to vibrating screens, and particularly relates to an anti-blocking net structure for a string tensioning screen. Background Art

[0002] The string relaxation screen is a device used for screening materials, primarily for screening 3mm and 6mm wet, sticky materials in coal and other mining industries. It utilizes flexible materials with excellent elasticity, offering significant advantages such as no clogging, a high throughput (up to 25t / m²), and self-cleaning meshes. Its flexible screen surface, due to the different tensions and amplitudes of adjacent strings and the height differences between adjacent strings, creates a three-dimensional dynamic mesh during vibratory screening, significantly increasing the open area ratio. During operation, the screen primarily screens through an anti-clogging net to prevent clogging. However, in actual use, it still suffers from the following drawbacks:

[0003] When the string tension screen anti-blocking net is working, it is directly screened through the anti-blocking net. However, when screening, the screen holes are directly formed by the tension difference between adjacent strings. However, during operation, the length of the gap between the two strings does not change, and its anti-blocking effect is not good enough;

[0004] The anti-blocking net of the string relaxation screen is installed in the vibrating screen when it is working. The material is transported to the anti-blocking net. However, during long-term operation, the material will remain in the gaps of the anti-blocking net, which makes the subsequent cleaning process inconvenient. Utility Model Content

[0005] The purpose of the utility model is to provide a string relaxation screen anti-blocking net structure. By arranging a screen body and an arc-shaped guide piece, the utility model solves the problems that the string relaxation screen anti-blocking net has an insufficient anti-blocking effect during operation and the screened materials are easily retained in the installation gap and are inconvenient to clean.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a string relaxation screen anti-blocking net structure, comprising a screen body and an arc-shaped guide piece, the screen body comprising side panels, connecting rods and elastic bending strips, the two side panels being arranged parallel to each other, a plurality of connecting rods being arranged in parallel between the two side panels, a plurality of elastic bending strips being arranged between two adjacent connecting rods, the elastic bending strip being arranged in the middle between the two adjacent connecting rods, triangular guide strips being fixed on the tops of the two side panels, an arc-shaped guide piece being fixed on the side of the triangular guide strip away from the elastic bending strip, when working, the material transported thereto is screened by the screen body when working, and the material entering the vibrating screen is escorted into the screen body by the arc-shaped guide piece when working.

[0008] Furthermore, the screen body also includes a fixed block, and two fixed blocks with equal spacing are fixed on the sides of the connecting rods close to the side plates. The fixed blocks are fixed on the side of the side plates close to the connecting rods. When the screen body is working, the connecting rods and the side plates are connected together through the fixed blocks.

[0009] Furthermore, the screen body also includes a diamond-shaped spring, and the ends of two adjacent connecting rods located at corresponding positions are both fixed with diamond-shaped springs. Each of the diamond-shaped springs is connected to a vertically fixed elastic plate, and the elastic bending strips close to the diamond-shaped springs are all fixed on the elastic plate. When the screen body is working, the elastic plate is connected through the elastic plate on the diamond-shaped spring.

[0010] Furthermore, each connecting rod is equidistantly and movably connected to a movable ring on its circumference, and two movable rings corresponding to the circumferences of two adjacent connecting rods are symmetrically fixed with bent springs on their circumferences. When the connecting rod is working, the bent spring is movably connected to the connecting rod through the movable ring.

[0011] Furthermore, an elastic strip is fixed between the two upper and lower corresponding and symmetrical bending spring sheets, and the ends of the elastic strip and the elastic bending strip are fixed to each other and connected to the elastic bending strip through the elastic strip.

[0012] Furthermore, a mounting bar is fixed to the top of the arc-shaped guide piece, and a mounting hole is opened on one side of the mounting bar along a center line parallel to the long side. When the arc-shaped guide piece is working, it is threadedly connected between the mounting hole on the mounting bar and the mounting bolt.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that the anti-blocking effect of the string relaxation screen is not good enough when working by arranging the screen body. When the screen body is installed on the vibrating screen, the vibrating screen can be started. When the vibrating screen is working, the screen body connected by the arc guide piece vibrates, and the material conveyed to the top of the screen body is screened. When vibrating, after the material falls on the screen body, the spacing between the elastic bending strip and the connecting rod changes continuously through vibration. At the same time, due to the bending and resetting of the diamond reed and the bent reed through vibration, the screening gap changes continuously during screening. When the material with a larger particle diameter blocks the gap on the screen during work, it will pop out due to the elastic effect, which reduces the probability that the screening gap on the screen body is blocked during work, and the anti-blocking effect is better.

[0015] The utility model solves the problem that the material screened by the string relaxation screen is easily retained in the installation gap and is inconvenient to clean by arranging an arc-shaped guide piece. After the mounting bar is brought into contact with the mounting position inside the vibrating screen, the mounting bolts are inserted into the mounting holes on the mounting bar, which are then screwed into the vibrating screen and tightened to complete the installation of the screen body. When the material falls into the vibrating screen during operation, the material falling onto the two side plates or the outside of the side plates is transported to the triangular guide bar through the arc-shaped guide piece, and is then transported to between the two side plates for screening through the triangular guide bar, thereby better preventing the material screened by the string relaxation screen from remaining in the installation gap and increasing the convenience of cleaning the material.

A plurality of connecting rods 103 are arranged in parallel between the two side plates 101. When the connecting rod 103 works, the bent spring 1032 is fixed thereon through the movable ring 1031. The connection between the two adjacent connecting rods 103 is A plurality of elastic bending strips 105 are arranged between them. When the elastic bending strips 105 are working, they are vibrated and bounce to prevent the material from being blocked during work. The elastic bending strips 105 are arranged in the middle between two adjacent connecting rods 103. The tops of the two side plates 101 are fixed with triangular guide strips 203. The side of the triangular guide strips 203 away from the elastic bending strips 105 is fixed with an arc-shaped guide piece 2. When working, the material is guided to the triangular guide strips 203 through the arc-shaped guide piece 2, and is guided to between the two adjacent side plates 101 through the triangular guide strips 203.

[0026] Specifically, the screen body 1 also includes a fixed block 102, and two fixed blocks 102 with equal spacing are fixed around the two connecting rods 103 close to the side plates 101. The fixed blocks 102 are fixed on the side of the side plates 101 close to the connecting rods 103.
