Sieve plate preventing material adhesion and vibrating screen with same

Abstract

The invention discloses a sieve plate preventing material adhesion and a vibrating screen with the same and belongs to the technical field of material sieving. A sieve face is provided with sieve holes. Sieve bodies are internally provided with supporting ribs, and the sieve face is supported by the supporting ribs. Separation parts are arranged between the periphery of the sieve face and the sieve bodies, and at the separation parts, the sieve face is disconnected from the sieve bodies. At least one side of the sieve face is provided with an extending part extending out of the sieve bodies. Supporting beams are provided with clamping strips. The two sides of the sieve bodies are in lap joint with the adjacent supporting beams. Clamping grooves between every two adjacent sieve bodies are clamped to the two sides of the corresponding clamping strips on the supporting beams in a matched manner. Connection joints between the sieve bodies are covered with the extending parts of the sieve face. According to the sieve plate preventing material adhesion and the vibrating screen with the same, the sieve face is separated from the supporting ribs, and when the vibrating screen works, the sieve face and the supporting ribs beat each other to prevent adhesion of wet and sticky materials; the connecting joints at the connection positions of the two sieve bodies are covered with the extending parts extending from the sieve face, the extending parts vibrate along with the vibrating screen, and adhering of the wet and sticky materials is avoided; and the separation parts are arranged between the sieve face and the sieve bodies, and the vibration effects of the sieve face and the extending parts of the sieve face are improved.

Description

technical field [0001] The invention relates to the technical field of material screening, in particular to a sieve plate for preventing material adhesion and a vibrating screen using the sieve plate. Background technique [0002] At present, when sieving wet and sticky materials, especially in the screening process of the blast furnace sieve in steel mills and ironworks, the common problem is that wet and sticky materials will adhere to the sieve plate, resulting in hardening of the screen surface material , Block the sieve holes, affecting the screening efficiency. [0003] Commonly used vibrating screens are mainly divided into two types: fixed screen surface and floating screen surface. At present, there is no good way to completely solve the problem of wet sticky materials sticking and hardening on the screen surface for fixed screen surface; floating screen surface can solve this problem. However, there are problems that the sieve body occupies a large space, the proc...

Problems solved by technology

[0006] The disadvantages of this kind of sieve plate are: the control of the particle size of the sieved material is weak, and the roughness under the sieve is serious. In addition, the wet sticky material will start to bond at the root of the steel rod and the frame, which will affect the vibration strength of the steel rod. Hardening will quickly develop from the root to the entire screen surface, making it difficult to clean the screen surface;

[0008] The defect of this kind of sieve plate is that although this kind of sieve plate can cause the material to be unable to adhere to the screen surface due to the severe deformation of the sieve surface during relaxation, the biggest problem with this structure is that the angle of the sieve surface is relatively large. Greater than 25°, the length of the screen surface is required to be
