Special vibrating screen mechanism for dry-process sand milling dust removal complete equipment

Abstract

The invention relates to a special vibrating screen mechanism for dry-process sand milling dust removal complete equipment, and the special vibrating screen mechanism can be used for producing and sorting a stone material, producing and sorting coarse sand, medium sand and fine sand, and preventing the stone material from clogging screen meshes. The special vibrating screen mechanism comprises a vibration screening mechanism, wherein a vibrating screen in the vibration screening mechanism comprises three layers of screen meshes, the three layers of screen meshes are spaced and distributed in the vertical direction, the mesh sizes of the three layers of screen meshes are different and gradually reduced from top to down, and an air blowing device is arranged above the third layer of screen mesh. The special vibrating screen mechanism provided by the utility model has the following advantages: (1) the special vibrating screen mechanism can be used for producing and sorting required stoneblocks, and producing and sorting required sand; (2) the special vibrating screen mechanism can be used for effectively preventing the stone material from clogging the screen meshes, so as to effectively prolong the service lives of the screen meshes; and (3) the special vibrating screen mechanism is not constrained by fields and climate, can operate in all weather conditions, and has no pollutant emission.

Description

technical field [0001] The invention relates to a special vibrating screen mechanism for dry-process sand grinding and dust removal complete sets of equipment which can not only produce stone materials by classification, but also produce coarse, medium and fine sand by classification, and can prevent stone materials from clogging the screen mesh. It belongs to the field of sand-making component assembly 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 re...

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
