Problems solved by technology

At the same time, due to the large section size of the fully mechanized excavator, conveyor belt, and blower in the excavation face, it is impossible to form a full-section spiral air flow in the roadway, so the effect of controlling and sealing dust is poor
Moreover, the size of the existing wall-attached air duct is huge, and it is difficult to advance and move with the excavation face, which seriously affects the excavation efficiency of the working face.

Abstract

The invention relates to an adjustable air flow distribution device and relates to the field of coal mine underground comprehensive dedusting and driving face ventilation. The adjustable air flow distribution device comprises a damper adjusting wrench (1), an air adjusting damper (2), a side air outlet (3), suspension lugs (4) and a shell (5), wherein the damper adjusting wrench (1) is arranged on one side of the outer wall of the shell (5) and connected with the air adjusting damper (2), the air adjusting damper (2) is radially arranged inside the shell (5), the suspension lugs (4) are arranged at the top end of the outer wall of the shell (5), and the side air outlet (3) is arranged on one side of the air adjusting damper (2). The adjustable air flow distribution device is capable of achieving side distribution of positive pressure air, portable in size and convenient to transport.

Description

Technical field: [0001] The invention relates to the field of coal mine comprehensive dust removal and tunneling face ventilation, in particular to an adjustable air flow distribution device. Background technique: [0002] At present, in the ventilation and dust removal system of fully mechanized excavation working face in China, the device to realize lateral air flow is the wall-attached air duct, which forms a spiral air flow in the roadway through the spiral structure of the attached wall air duct to control the enclosed dust, but the real realization of enclosed dust is due to The negative pressure formed by the suction port of the negative pressure fan makes the air flow move towards the negative pressure. At the same time, due to the large section size of the fully mechanized excavator, conveyor belt, and blower in the excavation face, it is impossible to form a full-section spiral air flow in the roadway, so the effect of controlling and sealing dust is poor.
