Atomizing dust removal and noise reduction system for down-the-hole drill and construction method

Abstract

The invention discloses an atomizing dust removal and noise reduction system for a down-the-hole drill and a construction method. The atomizing dust removal and noise reduction system involves a control component and a speed reducer, wherein a high-pressure air pipe is arranged on the control component, the high-pressure air pipe comprises an air outlet pipeline, a water supply pip is arranged onthe pipe wall of the air outlet pipeline in a communicating mode, the water supply pipe is used for supplying water to the air outlet pipeline, the air outlet pipeline is connected with a dust removalair inlet pipeline in the speed reducer, one end of a drill rod is connected to the power output end of the speed reducer, an impactor is connected to the other end of the drill rod, a drill bit is arranged on the impactor, the dust removal air inlet pipeline of the speed reducer communicates with the drill rod and an inner cavity of the impactor, and a dust removal hole of the drill bit is further connected to the inner cavity of the impactor in a communicating mode. According to the atomizing dust removal and noise reduction system, atomized water is conveyed and the effects of dust removaland noise reduction are achieved by connecting an existing high-speed air pipeline and a simple and easy water supply pipe, and the dust removal and noise reduction system has the advantages that theconstruction cost is reduced, the construction difficulty is simple, and the operation is easy.

Description

technical field [0001] The invention belongs to the technical field of down-the-hole drilling rigs, in particular to an atomization dust removal and noise reduction system and a construction method for down-the-hole drilling rigs. Background technique [0002] At present, when the drilling rig is drilling rock, a large amount of dust impacts upwards along the drill pipe, seriously polluting the air and operating environment, and increasing the equipment failure rate; the dust pollution caused by the operation will also cause the operator to have difficulty breathing and endanger the health of the operator And the surrounding environment, the traditional down-the-hole drilling rig operation method can no longer meet the environmental protection requirements of the current construction. [0003] In the prior art, the down-the-hole drilling rig uses a dust removal system to reduce dust during drilling operations on rocks. One is to use a simple covering box at the dust outlet o...
