Dust removal system for lower working face of raise boring

Abstract

The dust removal system comprises a roadway, a pipeline, a self-cleaning filter and a water curtain nozzle are arranged at the top of the roadway, a water inlet of the pipeline is connected with a movable main machine, the self-cleaning filter is arranged at the end, close to the water inlet, of the pipeline, and the water curtain nozzle is connected with the movable main machine. A fluid on the pipeline is communicated with a water curtain spray pipe, and the water curtain nozzle is arranged on the water curtain spray pipe; according to the invention, the self-cleaning filter is arranged, so that water flow can be filtered before entering the water curtain nozzle, impurities in the water flow are prevented from blocking the water curtain nozzle, the impurity content of a sprayed water curtain can be lower, more dust can be absorbed, and the dust removal efficiency is improved; and by arranging the self-cleaning filter, water in the roadway drainage ditch can be fed into the self-cleaning filter again through the high-pressure water pump to be filtered after being simply treated, so that the water can be repeatedly used, and water resources can be saved.

Description

technical field [0001] The invention relates to the technical field of roadway dust removal. Specifically, it is the dust removal system for the lower working face of raise drilling. Background technique [0002] The reverse shaft method is a bottom-up shaft construction method. The broken rocks fall freely into the bottom roadway during construction. During the rock breaking and falling process, a large amount of dust will be generated, which will cause harm to the underground roadway environment and employees. In severe cases, it will affect the construction of the underground working face. [0003] At present, there is an urgent need for an automatic dust removal device in the underground roadway, which can effectively filter the dust generated by the falling slag during the construction of the raised shaft, and minimize the impact on the construction of other underground working faces. Contents of the invention [0004] For this reason, the technical problem to be so...
