Problems solved by technology

However, as the ventilation continues, a large amount of dust will be trapped on one side of the dust filter, and will accumulate on the dust filter, resulting in blockage of the filter, which will greatly reduce the extraction efficiency of the air extraction equipment, and affect the subsequent discharge of dusty air, eventually resulting in The underground dust concentration cannot be effectively reduced, and in severe cases, it will threaten the safety of underground construction

Abstract

A disclosed dust filtering system for underground engineering ventilation comprises a base, a circular rotary groove is formed in the side wall of the base, a rotary drum is rotatably connected into the rotary groove in a sealed mode, a plurality of V-shaped partition plates are embedded in the inner wall of the rotary drum, a filter drum is fixedly connected into the rotary drum, and the V-shaped partition plates extend into the filter drum. A plurality of air inlets are formed in the side wall of the rotary drum, an air inlet pipe and an air outlet pipe which communicate with the interior of the rotary groove are installed on the base, permanent magnets are embedded in the air inlets, and iron sheets are embedded in the inner wall of the rotary groove. A traditional dust filter screen is made into a cylinder shape, the filter cylinder is divided into a plurality of filter areas through the V-shaped partition plates, when a certain filter area is blocked, deflection can occur under the action of gravity, then the blocked filter area is rotated away, meanwhile, another clean filter area is rotated to filter dust, and in this way, in the construction process, underground air is continuously and effectively purified, and safe construction is guaranteed.

Description

technical field [0001] The invention relates to the technical field of equipment related to underground engineering construction, in particular to a dust filter system for underground engineering ventilation. Background technique [0002] In the construction process of underground engineering, ventilation is a very critical construction step, which can extract the dusty air underground to ensure the safety of underground construction. [0003] In order to prevent the dust in the extracted air from polluting the atmosphere, a dust filter is added to the pipeline of the air extraction equipment to separate the dust in the air. However, as the ventilation continues, a large amount of dust will be trapped on one side of the dust filter, and will accumulate on the dust filter, resulting in blockage of the filter, greatly reducing the extraction efficiency of the air extraction equipment, and affecting the subsequent discharge of dusty air, eventually resulting in The underground...
