Description

Technical Field

[0001] The present invention belongs to the technical field of dust removal devices, and in particular relates to a dust removal device and method for use in mining engineering mines. Background Art

[0002] A large amount of dust is generated during ore mining operations. This dust not only endangers the health of miners and reduces the visibility and service life of equipment, but also spreads outside the mine, causing environmental pollution. Currently, the commonly used dust removal methods in mines mainly include wet dust removal and dry dust removal. Dry dust removal, especially filtering dust removal, is widely used due to its high efficiency in capturing fine dust and strong adaptability.

[0003] Existing dust removal devices used in mining mainly rely on negative pressure suction to collect dust-laden air near the dust source. However, in open or semi-open areas such as mining faces, dust is easily spread around after it is generated and is difficult to be effectively captured by the dust hood. In addition, large particles of dust and sticky dust can easily and quickly clog the pores of the filter material during the filtration process, which not only causes a sharp increase in system resistance and a decrease in dust removal efficiency, but also requires frequent shutdowns for manual cleaning or replacement of filter elements, which will seriously affect the operating efficiency of the dust removal equipment.

[0016] A method for using a dust removal device in a mining engineering mine comprises the following steps:

[0017] S1. When in use, first install the dust removal device on the mining equipment through the mounting bracket, then turn on the dust suction mechanism. The dust suction mechanism can suck the dust generated during ore mining into the cyclone separator. The cyclone separator can pre-centrifuge to remove large particles of impurities mixed in the gas. The gas separated and treated by the cyclone separator flows into the dust filter mechanism, which can perform secondary filtration to remove fine dust in the gas.

[0018] S2. The clean gas after secondary filtration and removal is regulated by a multi-stage regulating mechanism, then transported through the corrugated hose and hard gas pipe on the lifting and regulating mechanism, flows into the jet mechanism at a certain flow rate, and finally ejected from the slit nozzle at the bottom of the jet mechanism. The ejected gas forms a uniform and continuous air curtain, which can isolate the dust generated during ore mining and prevent dust from drifting and polluting the environment;

[0019] S3. When the gas separated and processed by the cyclone separator flows into the dust filtering mechanism, the airflow can be used to drive the pneumatic rotating mechanism to rotate. When the pneumatic rotating mechanism rotates, the elliptical linkage ring can be used to drive the cleaning mechanism to move up and down. The cleaning mechanism can automatically clean the dust intercepted and filtered on the outside of the dust filter element through the up and down reciprocating motion, which can effectively prevent the filter holes on the dust filter element from being clogged and affecting the use of dust removal. The height of the jet mechanism can be adjusted by the second hydraulic telescopic rod on the lifting and adjusting mechanism, which can be flexibly adjusted according to the height of the lane.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The height and suction angle of the dust suction mechanism can be adjusted at will according to the distribution of dust, with good dust suction effect and wide dust suction range. After the dust generated during ore mining is absorbed by the dust suction mechanism and sent to the cyclone separator, the large particles of impurities mixed in the gas can be pre-centrifuged by the cyclone separator, which can effectively prevent the large particles of dust from clogging the filter holes on the dust filter element. The gas separated and treated by the cyclone separator flows into the dust filter mechanism, and the fine dust in the gas can be secondary filtered and removed by the dust filter mechanism. The dust is treated by graded treatment, which can effectively prevent the filter holes on the dust filter mechanism from being blocked, and the filtering and dust removal effect is good.

[0022] 2. The gas filtered and purified by the dust filtering mechanism flows into the jet mechanism at a certain flow rate after being stabilized and regulated by the multi-stage regulating mechanism, and is finally ejected from the slit nozzle at the bottom of the jet mechanism. The ejected gas forms a uniform and continuous air curtain. The air curtain can isolate the dust generated during ore mining, and prevent the dust from drifting and polluting the environment. The clean air filtered by the dust removal equipment itself is used as the air source of the wind wall, which has the advantages of energy saving, environmental protection, and no introduction of additional pollution sources. Moreover, the dust isolated by the air curtain is concentrated in a small area, which is convenient for absorption by the dust suction mechanism, and can effectively improve the dust removal efficiency.

[0023] 3. By setting a multi-stage adjustment mechanism, the gas flow rate can be controlled at multiple levels through the multi-stage flow control valve on the multi-stage adjustment mechanism. It can be adjusted at multiple levels according to the speed of the dust suction fan. When the speed of the dust suction fan is high, the amount of gas inhaled is also large. At this time, the flow of the multi-stage flow control valve can be adaptively adjusted so that the purified gas can be ejected from the slit nozzle at a higher flow rate. When the air pressure in the pressure stabilizing chamber increases to a certain level, the air pressure can be used to push the piston assembly to one side. At this time, the piston assembly is misaligned with the pressure relief hole, and excess gas can be discharged through the pressure relief hole, which can effectively maintain the air pressure in the pressure stabilizing chamber and avoid danger caused by excessive pressure in the pressure stabilizing chamber. Conversely, when the speed of the dust suction fan decreases, the flow of the multi-stage flow control valve can be adaptively reduced so that the gas can be blown out evenly and continuously to form a continuous air curtain.

[0024] 4. When the gas separated and treated by the cyclone separator flows into the dust filtering mechanism, the airflow can be used to drive the pneumatic rotating mechanism to rotate. When the pneumatic rotating mechanism rotates, it can drive the cleaning mechanism to move up and down. The cleaning mechanism can automatically clean the dust intercepted and filtered on the outside of the dust filter element through the up and down reciprocating motion, which can effectively avoid the clogging of the filter holes on the dust filter element and affect the use of dust removal. There is no need to frequently stop the machine for manual cleaning. The height of the jet mechanism can be adjusted through the lifting adjustment mechanism, which can be flexibly adjusted according to the height of the lane. BRIEF DESCRIPTION OF THE DRAWINGS

Structure 6, and the multi-stage adjustment mechanism 5 is connected with the lifting adjustment mechanism 6. One end of the lifting adjustment mechanism 6 is fixedly connected with the jet mechanism 7. The jet mechanism 7 is used to spray out an air curtain to form a wind wall to isolate the dust generated during ore mining to prevent the dust from floating. The gas filtered and purified by the dust filtering mechanism 4 flows into the jet mechanism 7 at a certain flow rate after voltage stabilization and adjustment by the multi-stage adjustment mechanism 5, and is finally ejected from the slit nozzle 705 at the bottom of the jet mechanism 7. The ejected gas forms a uniform and continuous air curtain. The air curtain can isolate the dust generated during ore mining, and can prevent the dust from floating and polluting the environment. The clean air filtered by the dust removal equipment itself is used as the air source for the wind wall, which has the advantages of energy saving, environmental protection, and no introduction of additional pollution sources. Moreover, the dust isolated by the air curtain is concentrated in a small area, which is convenient for being absorbed by the dust suction mechanism 3, and can effectively improve the dust removal efficiency.

[0046] A pneumatic rotating mechanism 8 is provided between the cyclone separator 2 and the dust filtering mechanism 4. A dust cleaning mechanism 9 is linked to the outside of the pneumatic rotating mechanism 8. In the process of the gas separated and processed by the cyclone separator 2 flowing into the dust filtering mechanism 4, the airflow can be used to drive the pneumatic rotating mechanism 8 to rotate. When the pneumatic rotating mechanism 8 rotates, it can be linked to drive the dust cleaning mechanism 9 to move up and down. The dust intercepted and filtered on the outside of the dust filter element 405 can be automatically cleaned through the up and down reciprocating motion of the dust cleaning mechanism 9, which can effectively avoid the filter holes on the dust filter element 405 from being clogged, affecting the use of dust removal, and does not require frequent shutdown for manual cleaning.

The end of the output shaft of the rotating motor 304 is fixedly connected to an air collecting cylinder 305, and a dust collection hood 306 is fixedly arranged on one side of the air collecting cylinder 305. A dust collection pipe 307 is connected between the air collecting cylinder 305 and the dust collection fan 302.

[0048] As a further implementation scheme of the above invention: the dust filtering mechanism 4 includes an outer shell 401 and an inspection cabinet door 402 arranged on the outside of the outer shell 401, a partition plate 403 is fixedly provided in the inner cavity of the outer shell 401, and a pressure stabilizing chamber 404 is formed between the upper part of the partition plate 403 and the outer shell 401, and a dust filter element 405 is provided through the bottom of the partition plate 403. The interior of the dust filtering mechanism 4 can be inspected through the inspection cabinet door 402, and the fine dust in the gas can be intercepted and filtered through the dust filter element 405.

[0049] As a further implementation scheme of the above invention: a guide plate 406 is fixedly provided at the bottom of the inner cavity of the outer shell 401, and a through opening 407 and a rectangular guide hole are opened in the middle of the guide plate 406.

The through opening 407 is provided to facilitate gas circulation.

[0050] As a further implementation scheme of the above invention: the multi-stage regulating mechanism 5 includes a first cylinder 501 arranged at the top of the outer shell 401 and a multi-stage flow control valve 502 arranged at the top of the first cylinder 501, a second cylinder 503 is provided on one side of the first cylinder 501, and a pressure relief hole 504 and a spring member 505 are provided on the top and one side of the inner cavity of the second cylinder 503 respectively, and a piston assembly 506 is fixedly connected to one end of the spring member 505. The multi-stage flow control valve 502 on the multi-stage regulating mechanism 5 can perform multi-stage control of the gas flow, and can perform multi-stage adjustment according to the rotation speed of the dust suction fan 302. When the rotation speed of the dust suction fan 302 is higher, the amount of gas inhaled is also greater. At this time, the flow rate of the multi-stage flow control valve 502 can be adaptively adjusted so that the purified gas can be ejected from the slit nozzle 705 at a higher flow rate. When the air pressure in the pressure-stabilizing chamber 404 increases to a certain level, the air pressure can be used to push the piston assembly 506 to move to one side.

During specific use, the gas flows into the air collecting plate 602 through the corrugated hose 604 and one group of hard air pipes 603, and finally flows into the jet mechanism 7 through the remaining hard air pipes 603 to be ejected. By connecting the jet mechanism 7 with multiple groups of hard air pipes 603, the connection stability can be improved. The second hydraulic telescopic rod 601 can be used to control the lifting and lowering of the air collecting plate 602, and the height of the jet mechanism 7 can be adjusted, which can be flexibly adjusted according to the height of the alley.

When the rectangular upright rod 901 reciprocates up and down, it can drive the annular cleaning component 903 to reciprocate up and down to clean the dust on the surface of the dust filter element 405.

[0055] A method for using a dust removal device in a mining engineering mine comprises the following steps:

[0056] S1. When in use, first fix the mining dust removal device on the mining equipment through the mounting bracket, then turn on the dust suction mechanism 3. The dust suction mechanism 3 can suck the dust generated during ore mining into the cyclone separator 2. The cyclone separator 2 can pre-centrifuge to remove large particles of impurities mixed in the gas. The gas separated and treated by the cyclone separator 2 flows into the dust filter mechanism 4, which can perform secondary filtration to remove fine dust in the gas.

[0057] S2. After secondary filtration and removal, the clean gas is regulated by the multi-stage regulating mechanism 5, then transported through the corrugated hose 604 and the rigid gas pipe 603 on the lifting regulating mechanism 6, flows into the injection mechanism 7 at a certain flow rate, and is finally ejected from the slit nozzle 705 at the bottom of the injection mechanism 7. The ejected gas forms a uniform and continuous air curtain, which can isolate the dust generated during ore mining and prevent dust from drifting and polluting the environment;

[0058] S3. In the process of the gas separated and processed by the cyclone separator 2 flowing into the dust filtering mechanism 4, the airflow can be used to drive the pneumatic rotating mechanism 8 to rotate. When the pneumatic rotating mechanism 8 rotates, it can drive the cleaning mechanism 9 to move up and down through the elliptical linkage ring. The cleaning mechanism 9 can automatically clean the dust intercepted and filtered on the outside of the dust filter element 405 through the up and down reciprocating motion, which can effectively avoid the filter holes on the dust filter element from being clogged and affecting the use of dust removal. The height of the jet mechanism 7 can be adjusted by the second hydraulic telescopic rod 601 on the lifting adjustment mechanism 6, which can be flexibly adjusted according to the height of the lane.

[0059] In this embodiment, when in use, the dust removal device for mining is first fixedly installed on the mining equipment through the mounting base, and then the dust suction mechanism 3 is turned on. The dust suction mechanism 3 can suck the dust generated during ore mining into the cyclone separator 2. The cyclone separator 2 can pre-centrifugally remove large particles of impurities mixed in the gas. The gas separated and treated by the cyclone separator 2 flows into the dust filter mechanism 4. The dust filter mechanism 4 can perform secondary filtration and removal of fine dust in the gas. The dust is treated in a graded manner, which can effectively prevent the filter holes on the dust filter mechanism 4 from being clogged.

[0060] The gas filtered and purified by the dust filter mechanism 4 is regulated by the multi-stage regulating mechanism 5 and then flows into the jet mechanism 7 at a certain flow rate, and is finally ejected from the slit nozzle 705 at the bottom of the jet mechanism 7. The ejected gas forms a uniform and continuous air curtain, which can isolate the dust generated during ore mining and prevent the dust from drifting and polluting the environment. The clean air filtered by the dust removal equipment itself is used as the air source for the wind wall, which has the advantages of energy saving, environmental protection, and no introduction of additional pollution sources. In addition, the dust isolated by the air curtain is concentrated in a small area, which is convenient for absorption by the dust suction mechanism 3, thereby effectively improving the dust removal efficiency.

[0061] When the gas separated and processed by the cyclone separator 2 flows into the dust filtering mechanism 4, the airflow can drive the first pneumatic impeller 802 and the second pneumatic impeller 804 to rotate. When the first pneumatic impeller 802 and the second pneumatic impeller 804 rotate, they can drive the linkage sleeve 803 and the elliptical linkage ring 805 to rotate. When the elliptical linkage ring 805 rotates, it can cooperate with the linkage cam 902 to drive the rectangular vertical rod 901 to reciprocate up and down. When the rectangular vertical rod 901 reciprocates up and down, it can drive the annular dust cleaning component 903 to reciprocate up and down to clean the dust on the surface of the dust filter element 405.

[0062] The gas flow can be controlled in multiple stages through the multi-stage flow control valve 502 on the multi-stage adjustment mechanism 5, and can be adjusted in multiple stages according to the rotation speed of the dust suction fan 302. When the rotation speed of the dust suction fan 302 is relatively high, the amount of gas sucked in is also relatively large. At this time, the flow of the multi-stage flow control valve 502 can be adaptively adjusted so that the purified gas can be ejected from the slit nozzle 705 at a relatively high flow rate. When the air pressure in the pressure stabilizing chamber 404 increases to a certain level, the air pressure can be used to push the piston assembly 506 to move to one side. At this time, the piston assembly 506 is misaligned with the pressure relief hole 504, and excess gas can be discharged through the pressure relief hole 504, which can effectively maintain the air pressure in the pressure stabilizing chamber 404 and avoid the danger caused by excessive pressure in the pressure stabilizing chamber 404. On the contrary, when the rotation speed of the dust suction fan 302 decreases, the flow of the multi-stage flow control valve 502 can be adaptively reduced so that the gas can be blown out evenly and continuously to form a continuous air curtain.

[0063] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.

When in use, the dust removal device for mining is first fixedly installed on the mining equipment through the mounting base, and then the dust suction mechanism (3) is turned on. The dust suction mechanism (3) can suck the dust generated during ore mining into the cyclone separator (2). The cyclone separator (2) can pre-centrifugally remove large particles of impurities mixed in the gas. The gas separated and treated by the cyclone separator (2) flows into the dust filter mechanism (4). The dust filter mechanism (4) can perform secondary filtration and removal of fine dust in the gas. S2. The clean gas after secondary filtration and removal is regulated by the multi-stage regulating mechanism (5) and then transported through the corrugated hose (604) and the hard gas pipe (603) on the lifting regulating mechanism (6) to flow into the jet mechanism (7) at a certain flow rate, and finally ejected from the slit nozzle (705) at the bottom of the jet mechanism (7). The ejected gas forms a uniform and continuous air curtain, which can isolate the dust generated during ore mining and prevent the dust from floating and polluting the environment; S3. When the gas separated and processed by the cyclone separator (2) flows into the dust filtering mechanism (4), the air flow can drive the pneumatic rotating mechanism (8) to rotate. When the pneumatic rotating mechanism (8) rotates, the elliptical linkage ring can be used to drive the dust cleaning mechanism (9) to move up and down. The dust cleaning mechanism (9) that moves up and down can automatically clean the dust intercepted and filtered outside the dust filter element (405), which can effectively prevent the filter holes on the dust filter element from being clogged and affecting the use of dust removal. The height of the jet mechanism (7) can be adjusted by the second hydraulic telescopic rod (601) on the lifting adjustment mechanism (6), and can be flexibly adjusted according to the height of the roadway.
