Dust remover for drilling holes

Abstract

The invention relates to a dust remover for drilling holes, which is used for effectively solving the problems of usage unsafety, installation and maintenance complexity, large water consumption, high cost and poor dust removal effect. A dust collecting device is characterized in that straight pipes are connected into a whole through a tapered pipe and a three-way pipe, wherein a communicating pipe is arranged on the three-way pipe, and a first gas pipe and a first water pipe are arranged on the pipe wall at one end of the three-way pipe; and the dust remover is characterized in that a cylinder below a dished head at the upper part of the cylinder is provided with an airflow inlet, the front end of a bearing clapper overturning mechanism in the cylinder is pressed above a sealing member, the sealing member is fixed on the cylinder, a counterweight block is arranged at the lower part of the bearing clapper overturning mechanism, a dust hopper is arranged at the lower part of the cylinder, a second water pipe and a third water pipe which are mutually communicated with a filter and the first water pipe are arranged on the dished head, the filter is respectively connected with a pressure-reducing and pressure-stabilizing valve and a water-separating gas filter through a pneumatic ball valve, the water-separating gas filter is respectively communicated with a gas valve, the first gas pipe and a second gas pipe, the pressure-reducing and pressure-stabilizing valve is communicated with a fourth water pipe, and the gas valve is communicated with a third gas pipe. The dust remover has the advantage of safety and reliability, easiness of installation and maintenance and high dust removal efficiency.

Description

technical field [0001] The invention relates to a borehole dust remover. Background technique [0002] With the in-depth development of coal mine gas prevention and control work, the number of gas drainage drilling is bound to increase. In order to improve the hole formation rate, dry drilling with dust blowing and powder discharge at the bottom of the compressed air hole is often used, but a large amount of dust generated seriously endangers drilling operations. Personnel are in good health, so appropriate dust collection and removal measures must be taken. At present, there are many types of borehole dust collectors, such as water bath type, water jet type, multi-stage wet type, foam type, etc., and the following situations exist to varying degrees in normal use: [0003] 1. Working power is required, and the possibility of electric shock for workers increases, which is unsafe; [0004] 2. Waterways, electric circuits, compressed air channels, and mechanical transmissi...
