Abstract
The utility model relates to an air curtain dust separating device of a coal mining machine, which belongs to the field of the coal mining machinery and is used for separating dust at the position of the coal mining machine driver on the underground comprehensive mining surface of the coal mine. The separating device consists of a pneumatic pump 1, an air supply pipe 2, an air curtain main body section 3, an air inlet 4, a general control valve 5, a flow deflector 6, a strip seam plate 7, a supporting plate 8 and an inclined baffle 9. The compressed air provided with the underground pneumatic station or the pneumatic pump 1 of the coal mine can flow into the two air inlets 4 of the air curtain main body section 3 through the air supply pipe 2; the general control valve 5 is arranged at the position of the coal mining driver on the air supply pipeline; the rectangular air curtain which is made by welding a steel plate is provided with the flow deflector 6, the strip seam plate 7 and the supporting plate 8; and the inclined baffle 9 is arranged in the air curtain. The air curtain is arranged on the body of the coal mining machine. In the actual installation process, the air curtain can be properly extended along the windward upper roller; the requirements for the leeward lower roller can be properly lowered; and the air curtain is not necessarily required to be extended to the center position of the lower roller. When the coal mining machine cuts coal, the air curtain can be opened to greatly reduce the dust concentration at the driver side, improve the operating environment of the coal mining driver, and protect the occupational safety and health of the driver of the coal mining machine.
Description
Technical field
The utility model belongs to the coal-cutting machinery field, relates to a kind of air curtain dust-separation device and arrangement, is used under the coal mine fully-mechanized mining working coal-winning machine driver place and carries out dust-separation.
Background technology
Along with improving constantly of coal mining mechanization degree, the generation of mine dust is more and more, wherein fully-mechanized mining working is one of maximum dirt source of colliery dust-producing amount, the dust that produces during the fully-mechanized mining working operation is increasing to the influence of work plane working environment, and is especially particularly serious to coal mining driver's influence.For this reason, develop a kind of fully-mechanized mining working coal-winning machine air curtain dust-separation device and arrangement, the dust that can control the generation of coal-winning machine rolling cut effectively spreads to the coal-winning machine driver's side.
Summary of the invention
The utility model provides a kind of air curtain dust-separation device, and with its driver place that is installed in coal-winning machine, the operating environment at driver place and the purpose of driver physical health when reaching the coal cutting of protection coal-winning machine.
A kind of coal-winning machine air curtain dust-separation device is made up of compression pump 1, air supply pipe 2, air curtain main paragraph 3, air inlet port 4, master control valve 5, flow deflector 6, bar seam plate 7, gripper shoe 8, slanting baffle 9.The compressed air that compressor station or compression pump 1 provide under the coal mine enters two air inlet ports 4 of air curtain main paragraph 3 by air supply pipe 2, and supply air line is provided with master control valve 5 at coal mining driver place; Becoming on the air curtain of rectangular shape with welded steel plate, be provided with two flow deflectors 6, bar seam plate 7, gripper shoe 8, a slanting baffle 9 is established in air curtain inside.Two flow deflectors form the air curtain air port, and bar seam plate is embedded between two parallel conductive flows, is used for regulating the width in air curtain air port.For fear of the influence of bar seam plate pressurized wind, need establish gripper shoe and come firm bar seam plate.Because after pressing wind to enter from air inlet port, pressure can reduce gradually, therefore will establishing slanting baffle, to regulate the air curtain tuyere air volume even.
The utility model is achieved through the following technical solutions: the main paragraph 3 of air curtain all adopts thickness to adopt the welded steel plate of 3mm to form, and the welding of air curtain intermediate, inclined baffle plate 9 should be carried out simultaneously with the main paragraph welding, and weld does not stay the slit; Processing is separately adopted in the air curtain air port, is welded on the main paragraph after machining.Air curtain is processed as two sections, and air feed carries out air feed respectively from two ends; Consider the safety requirements of coal mine fully-mechanized mining working, air curtain is without the blower fan air feed, and the compressed air that utilizes compressor station under the coal mine or compression pump 1 to provide, supply air line 2 is provided with master control valve 5 at coal mining driver place, and compressed air is provided with the valve of regulating tolerance by air supply hose.Air curtain dust-separation device 10 is installed on the body of coal-winning machine 11, in the installation process of reality, can be suitably prolongs air curtains to the last cylinder 12 that facings the wind, for leeward to can suitably the lowering the requirement of bottom roll 12, needn't extend to the center of bottom roll.This is that the mode that air curtain is installed simultaneously like this can also stop the water smoke that the coal-winning machine external spraying produces, and purifies coal-winning machine driver's working environment because in the coal-winning machine actual job, the dust that the driver place is polluted mainly comes from cylinder.
Effect of the present utility model is: at the coal-face mean wind speed is that 1.5m/s, air curtain outlet mean wind speed are under the condition of 15m/s, coal-winning machine with the wind during coal cutting the average dust-separation efficient of full dirt be 86.10%, the average dust-separation efficient of full dirt is 83.43% during coal cutting against the wind.More than use the air curtain dust-separation device on the explanation coal-winning machine, in coal-winning machine coal cutting process, can reduce the dust concentration of driver's side greatly, improve coal mining driver's operating environment, protection coal-winning machine driver's occupational safety and health.
