Problems solved by technology

[0002] In the prior art, the known cantilever screen that can screen viscous materials is the used cantilever screen, but the cantilever screen is not specially designed for viscous materials. Therefore, it is not ideal for screening viscous materials, and there is no A more effective screening method and screening equipment for screening viscous materials, which are the shortcomings of the existing technology

Embodiment Construction

[0010] In order to clearly illustrate the technical characteristics of this scheme, the counterattack screening method and the counterattack sieve of this scheme using the falling energy of sieving materials will be described through a specific implementation mode and the accompanying drawings.

[0011] It can be seen from the accompanying drawings that the impact screen described in this program has a bracket 2, which is connected to the inclined box body 3 through a shock absorber 5, and the box body 3 has a feeding port connected to the feeding chute 10 below. 9. On-sieve material outlet 1, under-sieve material outlet 12 and vibration source 4. There is a screen 11 in the box body 3. The screen 11 described in this program is an elastic screen 11 and there are at least two , what this specific embodiment adopts is three screens 11. Each of the screens 11 is arranged in an inclined step, and at the outlet of the corresponding screen 11, there is a counter-attack plate 6 abov...

Abstract

The invention provides a method for screening materials in industry and an industrial sieve, in particular to an impact sieving method using energy of falling materials to be sieved and a technical proposal of an impact sieve. The technical proposal is as follows: a plurality of inclined and step-like screens are arranged up and down, and an impact board is arranged corresponding to an upper material outlet of each screen and above the next screen; the falling material to be sieved strikes a first screen to be sieved for the first time, the material is rebounded by the first screen, falls down to strike the impact board, then the material is reflected with the counteraction of the impact board and strikes the next screen to be sieved for the second time, and sieving of the material goes on like this. The impact sieve is characterized by the at least two screens in an inclined and step-like arrangement, and the material outlet on the sieve corresponding each screen, and the impact board which is arranged corresponding to the material outlet of each screen and above the next screen, and is fixed on a cross beam of a box body through a connecting rod.

Description

Technical field: [0001] The invention relates to a sieving method and an industrial sieve for industrially sieving materials, in particular to an impact screening method and an impact sieve utilizing the falling energy of the sieving material. Background technique: [0002] In the prior art, the known cantilever screen that can screen viscous materials is the used cantilever screen, but the cantilever screen is not specially designed for viscous materials. Therefore, it is not ideal for screening viscous materials, and there is no A more effective screening method and screening equipment for screening viscous materials are the shortcomings of the prior art. Invention content: [0003] The purpose of the present invention is to address the deficiencies in the prior art, and to provide a counterattack screening method using the falling energy of screening materials and a counterattack sieve technical scheme. The sieve feeding outlet of the net, there is a counterattack plat...
