Abstract
The utility model discloses a coal mine return air and dust absorption ventilation pipe which belongs to the field of underground ventilation pipes in coal mines, and comprises a main return air pipe and branch return air pipes; a plurality of joints of pipelines of the main return air pipe (1) are connected together through main return air pipe flanges (3); branch return air pipe flange seats (4) are distributed on both sides of the main return air pipe (1); each branch return air pipe flange seat (4) is provided with a branch return air pipe (2) or a flange cover (5); the main return air pipe (1) is arranged on a coal seam bottom surface on one side of a main mining roadway (6); the branch return air pipes (2) are arranged on the coal seam bottom surface on one side of a branch mining roadway (7); the outlet of the main return air pipe (1) is provided with a fan (8); and the coal mine return air and dust absorption ventilation pipe has simple structure, is convenient to assembly and use, can deploy different return air pipes depending on different mining roadways so as to meet the ventilation and dust absorption requirements of all the mining roadways, and is applicable to all coal mines.
Description
Technical field: the utility model relates to scavenge trunk, particularly a kind of colliery return air dust suction scavenge trunk.
Background technology: the ventilation of colliery return air dust suction at present, usefulness be that tunnel return air and down-hole blowing are ventilated.The colliery underworkings is many can to cause tunnel string wind, and following tunnel is calm.Also need three down-hole firebosses and a group leader and several down-holes blower fan, electric power is wasted in both wastes of manpower again, and down-hole ventilation effect and bad, does not reach the purpose of return air dust suction.
Summary of the invention: the purpose of this utility model is to provide a kind of colliery return air dust suction scavenge trunk, utilize this scavenge trunk that coal mine gas, coal dust are discharged from bottom surface, tunnel master's backwind tube, the swap-in fresh air helps the healthy of coal miner, both saving of labor, power savings again.
Formation of the present utility model: form by a main backwind tube and a backwind tube, main backwind tube is fused by main backwind tube flange by the more piece pipeline, at the both sides of a main backwind tube distribution backwind tube flange seat, a backwind tube or a blind flange are installed on a backwind tube flange seat.
Main backwind tube is installed on the bottom surface, coal seam of keeping to the side in the main tunnel of mining, and a backwind tube is installed on the bottom surface, coal seam of keeping to the side in a tunnel of mining, and in the outlet of main backwind tube blower fan is installed.
Compared with the prior art, the utility model is simple in structure, assembles easy to usely, can arrange different backwind tubes because of the coal cutting roadway difference, and each coal cutting roadway ventilates and the needs of dust suction so that adapt to.
Description of drawings: accompanying drawing is the utility model structural representation.
1. main backwind tubes among the figure, a 2. backwind tube, 3. main backwind tube flange, a 4. backwind tube flange seat, 5. blind flange, 6. main tunnel, 7. a tunnel, 8. blower fan.
The specific embodiment: as shown in the figure, main backwind tube 1 is fused by main backwind tube flange 3 by the more piece pipeline, and a backwind tube flange seat 4 that distributes in the both sides of main backwind tube 1 is installed a backwind tube 2 or a blind flange 5 on a backwind tube flange seat 4.
Main backwind tube 1 is installed on the bottom surface, coal seam of keeping to the side in the main tunnel 6 of mining, and a backwind tube 2 is installed on the bottom surface, coal seam of keeping to the side in a tunnel 7 of mining, and blower fan 8 is installed in the outlet of main backwind tube 1.
Claims (2)
1. colliery return air dust suction scavenge trunk, form by a main backwind tube and a backwind tube, it is characterized in that: main backwind tube (1) is fused by main backwind tube flange (3) by the more piece pipeline, at the both sides of main backwind tube (a 1) distribution backwind tube flange seat (4), go up installation at a backwind tube flange seat (4) and prop up a backwind tube (2) or a blind flange (5).
2. return air dust suction scavenge trunk in colliery according to claim 1, it is characterized in that: main backwind tube (1) is installed on the bottom surface, coal seam of keeping to the side in the main tunnel (6) of mining, prop up backwind tube (2) and be installed on the bottom surface, coal seam of keeping to the side in a tunnel (7) of mining, blower fan (8) is installed in the outlet of main backwind tube (1).
