Dust removal device for stone crushing and sand making discharging

Abstract

The invention discloses a dust removal device for stone crushing and sand making. The dust removal device comprises an air blower, a dust containing disc, a detector, a centrifugal dust collector, anexternal water storage tank, a sewage drainage channel, a feeding blocking door, a centrifugal machine shaft, a centrifugal fan plate, a centrifugal motor, an operation spray head, an air blowing motor, an air blowing channel, an air blowing opening, a blocking door rotating shaft and a baffle. On one hand, the air blower starts to work, so that dust generated by working cannot escape from the feeding blocking door; and on the other hand, the centrifugal dust collector starts to work centrifugally to form internal ultra-low pressure, so that a large amount of dust in a stone crushing and sandmaking tank is sucked in. At the moment, the operation spray head continuously sprays water, a large amount of sucked dust forms sewage along with water flow, and the sewage flows into a sewage treatment tank along the sewage drainage channel; and meanwhile, the dust containing disc and the detector at the top of the stone crushing and sand making tank detect the dust concentration in the stone crushing and sand making tank constantly, and normal and effective operation of the dust removal device is guaranteed.

Description

technical field [0001] The invention relates to the field of crushed stone sand making, in particular to a dust removal device for making crushed stone sand and discharging materials. Background technique [0002] The mining machinery industry has little research and development investment, small enterprise scale, low technological content of products, one-sided pursuit of main engine output, and the main engine is getting bigger and bigger, with few breakthrough technologies, and still stays in the traditional mechanical mode. Specifically, there are the following problems: First, the crushed stone sand making machinery still adopts the traditional mechanical principles and processes, resulting in the widespread occurrence of powder and needle flakes exceeding the standard, sand powder separation, and continuous gradation in the finished sand produced by sand and gravel production enterprises. Quality problems such as non-compliance will affect the strength of concrete and ...

Problems solved by technology

Specifically, there are the following problems: First, the crushed stone sand making machinery still adopts the traditional mechanical principles and processes, resulting in the widespread occurrence of powder and needle flakes exceeding the standard, sand powder separation, and continuous gradation in the finished sand produced by sand and gravel production enterprises. Substandard and other quality problems affect the strength of concrete and the quality of infrastructure projects, and cannot meet the requirements of national large-scale project construction

Second, sand and gravel production enterprises adopt open-air production, and the dust generated by crushed stone sand making will pollute the air environment; at the same time, in order to reduce the powder content of the finished sand, the finished sand is generally washed with water, which also causes waste water to pollute the water environment

[0003] Chinese Patent Authorization Announcement No. CN202700602U proposes a crushed stone sand making production line, which can efficiently sand and discharge stone materials; however, there is the same problem as most of the existing products of this type, the dust produced by crushed stone sand making At the same time, in order to reduce the powder content of the finished sand, the finished sand is generally washed with water, and the waste water pollutes the water environment. At present, there is no relevant existing technology to solve these problems, so it is necessary to improve
