All-weather zero-discharge outdoors-sand-making-system composite vibrating screen mechanism and anti-blocking method

Abstract

The invention relates to an all-weather zero-discharge outdoors-sand-making-system for special-purpose composite vibrating screen mechanism and an anti-blocking method, which can not only effectively separate stone materials, but also can effectively separate coarse sand and medium sand from fine sand and effectively prevent the sand from blocking the screen mesh. The mechanism comprises the vibrating screen mechanism, wherein the vibrating screen of the vibrating screen mechanism is composed of a screen mesh with three layers; the three layers are distributed up and down at regular intervals and each has different apertures, lessened gradually from the top down; a blowing device is arranged above the third-layer screen mesh; a plurality of spring balls are arranged on a wind pipe of the blowing device; a water mist dust-covering hood is arranged on the top of a feeding inlet of the vibrating screen mechanism; and a discharge port of the vibrating screen mechanism is provided with a dust-absorbing hood. The mechanism and method provided by the invention have the advantages that on a set of system, not only can the stone materials be processed by steps, but also the coarse sand, the medium sand and the fine sand can be produced by steps, and the purpose of all-weather production and zero-discharge can be achieved simultaneously.

Description

technical field [0001] The invention relates to a composite vibrating screen mechanism and an anti-clogging method for an all-weather zero-emission open-air sand making system that can effectively sort stones, and can effectively sort coarse, medium and fine sands and can effectively prevent sand from clogging the screen. , which belongs to the field of vibrating screen mechanism manufacturing. Background technique [0002] CN101362112A, name "a dry sand making method and the dry sand making machine used", including a hollow crushing working chamber (2), and a hollow dust removal working chamber (5) is provided below the crushing working chamber (2) , the upper end of the feeding channel (6) is sealed and connected with the feeding port (22), the lower end (61) of the feeding channel (6) is located in the dust removal working chamber (5), and the dust removal working chamber (5) is also provided with Vent (7), air duct (8) are located in the dust removal working chamber (5)...

AI Technical Summary

Problems solved by technology

[0007] The homogeneity of the above-mentioned background technology neither solves the phenomenon of screen resonance, nor solves the phenomenon of stone blocking the screen holes; second, it neither solves the physical hazards of dust to operators, nor solves the problem of environmental pollution by powder method; The third is that neither the recycling of tailings materials nor the multi-stage sorting and production of stone materials have been realized; the fourth is that it is impossible to produce in rainy days, and it is also necessary to ensure that the stones are dry. The production conditions are restricted by the climate and cannot be realized at all. All-weather open-air production
