Abstract

The invention provides a totally-closed blowout prevention dust falling device which is characterized in that a transverse dust baffle is arranged in a blowout prevention box body, the dust baffle is installed on the inner wall of a dust prevention box body, and a backflow opening is formed between the dust baffle and the inner wall of the dust prevention box body; an air inlet and an air outlet are formed in a top plate of the blowout prevention box body, and the air outlet is located above the dust baffle; the air inlet pipe is inserted into the blowout prevention box body from the air inlet and penetrates through the backflow port; the air outlet pipe is installed on the air outlet. According to the invention, the hole spraying prevention and dust removal effects in the drilling construction process are improved, the working environment is improved, and the safety is guaranteed.

Description

technical field [0001] The invention relates to the field of coal mine production equipment, in particular to a fully enclosed blowout prevention and dust reduction device. Background technique [0002] During the drilling construction of coal mine production, the original coal body is damaged and a large amount of gas gushes out of the hole, resulting in frequent accidents of gas exceeding the limit during the construction process, and the dust concentration in the roadway during dry slag discharge is high, seriously Restricting production safety and the health of workers. In order to solve the above problems, a fully enclosed spray-proof and dust-reducing device was reprocessed, which successfully solved the problems of excessive gas and high dust concentration, and ensured safe production and working environment for employees. Contents of the invention [0003] The invention provides a fully enclosed anti-blowout and dust-reducing device, the purpose of which is to sol...
