Description

Technical Field

[0001] The invention relates to the technical field of excavation dust removal, and in particular to a dust reduction device based on underground tunnel development and excavation. Background Art

[0002] Underground tunnel development refers to the process of excavating passages underground in a mine, with the aim of creating the necessary space and passages for mining, transportation, ventilation and drainage operations. This process usually includes designing the direction of the tunnel, crushing rocks by drilling and blasting or mechanical excavation, transporting the crushed rocks out of the tunnel, and supporting them to ensure the stability of the tunnel. At the same time, ventilation and drainage systems need to be installed to ensure a safe environment for underground operations. Development and excavation is a basic link in mining, and its efficiency and quality directly affect the smooth progress of subsequent mining operations. During the excavation process, drilling, blasting, loading and other operations will generate a lot of dust, which not only affects visibility, but may also cause respiratory diseases or explosion risks. Therefore, ventilation and dust removal are usually used: by installing local ventilation equipment (such as fans and air ducts), dust-containing air is discharged from the tunnel and fresh air is introduced at the same time; dust removal measures can not only effectively reduce dust hazards, but also improve operational safety and ensure the health and work efficiency of underground personnel.

[0003] In coal and gas outburst mines, the pressure-type dust removal system uses local ventilators to forcefully deliver fresh air to the excavation working face through flexible air ducts, and cooperates with wet dust removal equipment to form a comprehensive dust prevention system.

[0004] In the existing dust removal process using a fan, the dust in the area is generally reduced by using a filter combined with a spray to absorb dust. However, after a period of use, especially when a large amount of dust suddenly appears, the dust is easy to clog the filter holes, resulting in a decrease in the dust reduction efficiency. Therefore, a dust reduction device for cleaning the filter is proposed. Summary of the invention

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0035] In the related technology, the existing dust removal process using a fan generally adopts the principle of using a filter screen in combination with a spray to absorb dust to reduce the dust in the area. However, after a period of use, especially when a large amount of dust suddenly appears, the dust is easy to clog the filter screen holes, resulting in affecting the dust reduction efficiency. Therefore, a dust reduction device for cleaning the filter screen is proposed.

[0036] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides a dust suppression device based on underground tunnel development and excavation. By connecting to external water, when the water flows through the spiral blades, the spiral blades are driven to rotate. At this time, the water generates a vortex, thereby driving the disc to rotate on the pipe body. Finally, the water is sprayed out through multiple nozzles. The sprayed water is adsorbed by the dust, thereby treating the dust. The spray area is increased by rotating the spray, and the efficiency of dust treatment is further improved.

[0037] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0038] Combination Figure 1-Figure 6 The embodiment of the present application provides a dust suppression device based on underground tunnel development and excavation, including a cylinder 100, a fan cylinder 140 is fixed to one end face of the cylinder 100, a plate 110 is fixed to the other end face, a connecting end 120 is fixed to one end face of the plate 110, a liquid inlet pipe 130 is fixed to the plate 110, the liquid inlet pipe 130 passes through the plate 110 and extends to the inside of the plate 110, a filter screen 400 is arranged inside the cylinder 100, and a joint is fixed to the bottom end of the liquid inlet pipe 130 230, the liquid outlet end of the connector 230 is fixedly connected to the tube body 200, one end of the tube body 200 is connected to the disk body 210, the outer wall of the disk body 210 is fixed with the tube body 220, and a plurality of nozzles are arranged on the tube body 220, the inner wall of the connector 230 is rotatably connected with the spiral blade 240, when the water flows through the tube body 200, the spiral blade 240 is driven to rotate, so that the water flow generates a vortex, and drives the disk body 210 to rotate on the tube body 200, and the outer wall of the cylinder body 100 is fixed with the waste liquid pipe 150.

[0039] Specifically, when in use, first, the rear of the fan in the forced ventilation system is connected in series to the connection end 120. At this time, the normal operation of the forced ventilation system forces fresh air into the working surface, and at the same time, the dirty air is naturally discharged along the lane, and the fan cylinder 140 is controlled to work, and the air in the rear area is sucked into the cylinder body 100. Secondly, while the fan cylinder 140 is working, the liquid inlet pipe 130 is connected to external water, and the water is introduced into the multiple tube bodies 220 through the tube body 100, and is sprayed out through multiple nozzles. The sprayed water is adsorbed by the dust, thereby the dust is removed. The dust is processed, and the adsorbed liquid is discharged through the waste liquid pipe 150. In the process of water passing through the tube body 200, the spiral blade 240 rotates in the joint 230. At this time, the water generates a vortex, and the vortex drives the disk 210 to rotate on the tube body 200, so that multiple nozzles start to rotate, thereby increasing the range of the spray and the effect of dust reduction. Finally, the dust-reduced gas is discharged into the filter component through the fan barrel 140, and is filtered and discharged by the filter component. The filter component is not drawn in the attached figure and belongs to the prior art, which is not described here, thereby ensuring the overall sedimentation rate.

[0040] In some embodiments, a frame 310 is disposed on the inner wall of the cylinder 100 , and regularly arranged rods 320 are disposed on one side of the frame 310 . The rods 320 can pass through the filter holes on the filter screen 400 .

[0041] Specifically, the rod-shaped object 320 may be a steel wire, an iron wire, etc. The rod-shaped object 320 passes through the filter holes on the filter screen 400 , and can remove the dust blocked in the filter holes, thereby ensuring the normal ventilation of the filter screen 400 .

[0042] Specifically, a differential pressure sensor may be installed before and after the filter 400 to monitor the pressure. When ΔP reaches a certain threshold, maintenance personnel are required to check whether the filter 400 and the rod 320 need to be cleaned. For example, the threshold is ΔP>500Pa.

[0043] In some embodiments, a transmission assembly is disposed on one side of the frame 310, and the transmission assembly is used to drive the frame 310 to move laterally on the inner wall of the cylinder 100, so that the rod 320 passes through the filter hole, and one end of the spiral leaf 240 is connected to the transmission assembly.

[0044] Specifically, the spiral blade 240 rotates while driving the transmission assembly to work, and the transmission assembly drives the frame 310 to perform horizontal reciprocating motion on the cylinder 100, thereby driving the rod 320 to penetrate the filter holes, and repeating the operation to reduce the dust in the filter holes on the filter screen 400.

[0045] In some embodiments, the transmission assembly includes a screw 330 , the screw 330 is fixedly connected to the spiral blade 240 , the screw 330 is threadedly connected to the frame 310 , and the screw 330 is a bidirectional screw.

[0046] Specifically, the rotation of the spiral blade 240 drives the screw 330 to rotate. The screw 330 is threadedly connected to the frame 310, driving the frame 310 to make horizontal reciprocating motion on the inner wall of the cylinder 100, thereby utilizing the driving force of the spiral blade 240 to change the position of the rod 320, so that the filter 400 can be cleaned.

[0047] In some embodiments, a sleeve 300 is sleeved on the outside of the frame 310 , and the sleeve 300 is fixed to the frame 310 and the disk 210 respectively.

[0048] Specifically, when the frame 310 moves laterally, the sleeve 300 also expands and contracts accordingly, thereby protecting the screw 330 and preventing dust or liquid from affecting the operation of the screw 330 .

[0049] In some embodiments, a connection frame 520 is fixed to the inner wall of the cylinder 100 , one end of a spring 510 is fixed to one side of the connection frame 520 , and the other end of the spring 510 is fixed to the filter screen 400 .

[0050] Specifically, when the rod-shaped object 320 rubs and penetrates the filter holes of the filter screen 400 , the filter screen 400 will compress the spring 510 , and the elastic return of the spring 510 drives the filter screen 400 to vibrate, further shaking off the dust on the filter screen 400 .

[0051] In some embodiments, an impact assembly is fixed to one side of the frame 310, and the impact assembly includes a column 500. The column 500 is fixed to one side of the frame 310, a block 530 is provided on the outer wall of the column 500, a slot is provided on the inner wall of the filter 400, a turntable 600 is fixed to one end of the screw 330, and a brush 610 is fixed to the outer wall of the turntable 600.

[0052] Specifically, when the frame 310 moves to a side close to the filter 400, the column 500 is driven to move, and the block 530 squeezes one side of the filter 400, driving the filter 400 to further squeeze the spring 510. When the column 500 moves to a certain position, the block 530 shrinks into the column 500 and moves to the other side of the filter 400 through the through hole on the inner side of the filter 400. At this time, the elasticity of the spring 510 resets the filter 400, and the filter 400 is vibrated. The block 530 is connected to the column 500 by a spring, which is not shown in the drawings.

[0053] When the block (530) is subjected to a squeezing force exceeding a preset value, it will retract into the interior of the column (500) and smoothly pass through the filter screen 400 to the other side of the filter screen 400.

[0054] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification.

[0055] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.
