Description

Technical Field

[0001] This utility model relates to the technical field of dust removal devices, and in particular to a dust removal device for coal mine safety production tunnels. Background Technology

[0002] Dust suppression systems in coal mine tunnels are core equipment used to improve the underground working environment and ensure safe production during coal mining operations. They are defined as an integrated system that collects, settles, and purifies dust within coal mine tunnels through physical or chemical means. This system typically consists of a spray dust suppression system, a dust collection and filtration system, and a power control system. The spray dust suppression system evenly sprays water mist into the tunnel space through spray nozzles on pipes, utilizing the combination of water mist and dust to increase their weight and cause them to settle. The dust collection and filtration system uses a fan to generate negative pressure, drawing suspended dust into the filtration device, where it is intercepted and purified by the filter before being discharged as clean air. The power control system is responsible for adjusting parameters such as spray pressure and suction airflow to ensure efficient operation of the dust suppression process.

[0003] Currently, to achieve efficient dust suppression, most coal mine tunnel dust removal devices adopt pipeline spray systems, with spray heads densely arranged on the pipelines to cover a large dust removal area. While this design can meet basic dust suppression needs, the high dust concentration in coal mine tunnels makes it easy for dust to adhere to the surface of the spray heads or clog the nozzles, leading to weakened or even ineffective spraying. Furthermore, existing spray pipelines are mostly connected to the dust removal device using welding or bolting, resulting in a relatively fixed structure. When a spray head becomes clogged, maintenance personnel must first shut down the dust removal system and related power equipment, and then use tools to disassemble the connecting parts between the pipeline and the device before the pipeline can be removed for cleaning. This process is not only cumbersome and time-consuming, but also potentially inconvenient due to limited space and difficulty in operation during disassembly. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a dust removal device for coal mine safety production tunnels, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a dust removal device for coal mine safety production tunnels, including a base. Two symmetrically arranged rails are fixedly connected to the top surface of the base. A coal mine transport vehicle is slidably connected to the top of the two rails. Two symmetrically arranged support frames are fixedly connected to the top surface of the base. The coal mine transport vehicle is located between the two support frames. A hydraulic cylinder is fixedly connected inside each support frame. A lifting plate is fixedly connected to the output end of each hydraulic cylinder. Two symmetrically arranged guide columns are fixedly connected to the bottom surface of each lifting plate. Several guide columns are slidably connected to the two support frames respectively. A threaded column is threadedly connected to the top surface of each lifting plate. A guide frame is rotatably connected to one end of each threaded column near the coal mine transport vehicle via a bearing. Several linearly arrayed pipe bodies are arranged above the coal mine transport vehicle. Several nozzles are fixedly connected to the bottom of each pipe body. An assembly plate is fixedly connected to two of the two pipe bodies. The two assembly plates are respectively engaged with two guide frames.

[0007] Preferably, one side of each of the above-mentioned flow guide frames is provided with a plurality of linear array through holes, and the main body of the pipe is connected to the flow guide frame through the through holes.

[0008] Preferably, in any of the above embodiments, a sealing ring is fixedly connected to the side of the assembly plate away from the main body of the pipe, and a plurality of linear array sealing grooves are opened on one side of the flow guide frame, and the sealing ring is slidably connected to the flow guide frame through the sealing grooves.

[0009] Preferably, in any of the above schemes, two symmetrically arranged water inlet pipes are fixedly connected to the side of the guide frame away from the main pipe body, and two symmetrically arranged guide sleeves are fixedly connected to the top surface of the lifting plate, with the two water inlet pipes slidably connected to the two guide sleeves respectively.

[0010] Preferably, in any of the above solutions, the top surface of the lifting plate is fixedly connected to two limiting posts, and the left and right ends of the guide frame are slidably connected to the two limiting posts respectively.

[0011] Preferably, in any of the above solutions, a plurality of linearly arrayed brackets are fixedly connected to the side of the lifting plate near the main body of the pipe. A magnet plate is embedded in the inner wall of each bracket. The outer surface of the main body of the pipe is in contact with the top surface of the magnet plate. A plurality of symmetrically arranged positioning pins are fixedly connected to the outer surface of the main body of the pipe. The main body of the pipe is engaged with the brackets by the positioning pins.

[0012] Preferably, one side of the support frame is threaded with a locking bolt, and the threaded part of the locking bolt is in contact with the guide post.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. Addressing the cumbersome cleaning process of nozzles in traditional coal mine dust collectors after they become clogged, this dust collector utilizes a snap-fit ​​design between the assembly plate and the guide frame to achieve rapid disassembly of the main pipe body. When a nozzle becomes clogged, there is no need to shut down the entire dust collection system. Simply twist the threaded post to separate the guide frame from the main pipe body. The sliding engagement of the sealing ring and sealing groove between the assembly plate and the guide frame allows for easy removal of the main pipe body for cleaning. Simultaneously, the main pipe body is snapped into the bracket by positioning pins, with magnetic plates providing additional fixation. Disassembly simply requires releasing the snap-fit ​​and magnetic attachment for quick removal of the main pipe body. This design avoids the complex disassembly process of traditional welding or bolt fixing methods, significantly shortening cleaning time, reducing equipment downtime due to nozzle cleaning, lowering worker workload, and facilitating operation even in confined tunnel spaces.

[0015] 2. This coal mine safety production tunnel dust removal device achieves flexible and efficient dust removal operation through the coordinated operation of multiple components. During use, the coal transport vehicle moves along the track between two support frames. The hydraulic cylinder is activated to push the lifting plate up and down along the guide column, adjusting the height of the guide frame and the main pipe body to accommodate coal transport vehicles of different heights. After the height is adjusted, the locking bolts on one side of the support frame are tightened to fix the guide column, ensuring the stability of the main pipe body. The water inlet pipe is slidably connected to the guide sleeve, ensuring stable water connection during lifting. Water flows through the through-hole into the main pipe body and is sprayed out through the nozzles for dust removal. Limiting columns limit the guide frame to prevent it from shifting, and brackets and magnetic plates further fix the main pipe body. This design allows for flexible adjustment of the height and position of the main pipe body according to the actual transport vehicles and dust removal needs. Simultaneously, it provides continuous and efficient dust reduction during transportation, improving the dust removal effect. The entire operation process is simple and adaptable to the complex and varied working environment of coal mine tunnels. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0023] like Figures 1 to 5 As shown, a dust removal device for coal mine safety production tunnels includes a base 1. Two symmetrically arranged rails 2 are fixedly connected to the top surface of the base 1. A coal mine transport vehicle 3 is slidably connected to the top of the two rails 2. Two symmetrically arranged support frames 4 are fixedly connected to the top surface of the base 1. The coal mine transport vehicle 3 is located between the two support frames 4. A hydraulic cylinder 5 is fixedly connected inside each support frame 4. A lifting plate 6 is fixedly connected to the output end of each hydraulic cylinder 5. Two symmetrically arranged guide columns 7 are fixedly connected to the bottom surface of each lifting plate 6. Several guide columns 7 are slidably connected to the two support frames 4 respectively. A threaded column 8 is threadedly connected to the top surface of each lifting plate 6. A flow guide frame 9 is rotatably connected to one end of each threaded column 8 near the coal mine transport vehicle 3 via a bearing. Several linear array of pipe bodies 10 are arranged above the coal mine transport vehicle 3. Several nozzles 13 are fixedly connected to the bottom of each pipe body 10. An assembly plate 11 is fixedly connected to the two pipe bodies 10 respectively. The two assembly plates 11 are respectively engaged with the two flow guide frames 9.

[0024] As an optional technical solution of this utility model, each guide frame 9 has a plurality of linearly arrayed through holes 12 extending through one side. The main body of the pipe 10 is connected to the guide frame 9 through the through holes 12. During dust removal operations, water flows into the guide frame 9 from the inlet pipe 16 and can flow into the main body of the pipe 10 evenly and efficiently through these linearly arrayed through holes 12, and then spray out from the nozzle 13. This design ensures stable water pressure throughout the main body of the pipe 10, enabling the nozzle 13 to perform dust removal operations with a uniform spray effect, avoiding poor dust removal effect in some areas due to uneven water distribution, and improving the overall working efficiency of the dust removal device.

[0025] As an optional technical solution of this utility model, a sealing ring 14 is fixedly connected to the side of the assembly plate 11 away from the main pipe body 10. A plurality of linearly arrayed sealing grooves 15 are opened on one side of the guide frame 9. The sealing ring 14 is slidably connected to the guide frame 9 through the sealing grooves 15. During installation, the sealing ring 14 is aligned with the sealing groove 15 and inserted, quickly completing the connection between the main pipe body 10 and the guide frame 9, making the operation simple. During the operation of the dust removal device, the sealing ring 14 and the sealing groove 15 fit tightly, effectively preventing water leakage from the connection point, avoiding water waste and equipment failure due to leakage. Furthermore, this sealing structure can also prevent dust from the coal mine tunnel from entering the connection point, reducing the risk of blockage of the internal water flow channel and ensuring the long-term stable operation of the dust removal system.

[0026] As an optional technical solution of this utility model, two symmetrically arranged water inlet pipes 16 are fixedly connected to the side of the guide frame 9 away from the main body of the pipe 10, and two symmetrically arranged guide sleeves 17 are fixedly connected to the top surface of the lifting plate 6. The two water inlet pipes 16 are slidably connected to the two guide sleeves 17 respectively. When the hydraulic cylinder 5 drives the lifting plate 6 to move the guide frame 9 up and down, the water inlet pipes 16 can slide smoothly within the guide sleeves 17, and there will be no problems such as water pipe twisting, bending or falling off due to the lifting action, thus maintaining the smooth delivery of water. This design allows the dust removal device to flexibly adjust the height of the main body of the pipe 10 according to actual needs, adapting to different specifications of coal mine transport vehicles 3, and there is no need to interrupt the water supply during the height adjustment process, ensuring the continuity of dust removal operations and enhancing the applicability and flexibility of the device.

[0027] As an optional technical solution of this utility model, two limiting posts 18 are fixedly connected to the top surface of the lifting plate 6. The left and right ends of the guide frame 9 are slidably connected to the two limiting posts 18 respectively. During the process of the lifting plate 6 driving the guide frame 9 to rise and fall, the limiting posts 18 restrict the guide frame 9 to move only in the vertical direction, preventing it from deviating or shaking during the rising and falling process, and ensuring that the pipe body 10 is always in the accurate dust removal position. At the same time, when the pipe body 10 is subjected to water pressure or external collisions, the limiting posts 18 can provide support to prevent the guide frame 9 from shifting and ensure the connection stability between the pipe body 10 and the guide frame 9.

[0028] As an optional technical solution of this utility model, a number of linearly arrayed brackets 19 are fixedly connected to the side of the lifting plate 6 near the pipe body 10. A magnetic plate 20 is embedded in the inner wall of each bracket 19. The outer surface of the pipe body 10 is in contact with the top surface of the magnetic plate 20. A number of symmetrically arranged positioning pins 21 are fixedly connected to the outer surface of the pipe body 10. The pipe body 10 is engaged with the brackets 19 through the positioning pins 21. When installing the pipe body 10, the positioning pins 21 are inserted into the engagement position of the brackets 19 to achieve initial fixation. At the same time, the magnetic plates 20 attract the pipe body 10, further enhancing the fixation effect and preventing it from loosening or falling off during operation. When it is necessary to disassemble the pipe body 10 for cleaning and maintenance, the positioning pins 21 can be easily pulled out from the brackets 19 to remove the pipe body 10. The operation is simple and quick. This design not only ensures the stability of the pipe body 10 in dust removal operations, but also facilitates daily inspection and maintenance, improving the practicality and maintainability of the device.

[0029] As an optional technical solution of this utility model, a locking bolt 23 is threadedly connected to one side of the support frame 4. The threaded part of the locking bolt 23 is in contact with the guide column 7. After the lifting plate 6 is adjusted to a suitable height by the hydraulic cylinder 5, the locking bolt 23 is tightened to make its threaded part fit tightly with the guide column 7, thereby locking the lifting plate 6 and preventing it from shifting due to vibration, water pressure, or other factors during dust removal operations. This locking method is simple to operate, requires no complicated tools, and allows the height of the lifting plate 6 to be adjusted and locked at any time according to actual needs, ensuring that the main body of the pipeline 10 and the nozzle 13 are always in the optimal dust removal position, and ensuring the stable and efficient operation of the dust removal device.

[0030] A dust removal device for safe production in coal mine tunnels operates on the following principle:

[0031] 1) When the nozzle 13 becomes clogged, there is no need to shut down the entire dust removal system. Simply turn the threaded column 8 to separate the guide frame 9 from the pipe body 10. By utilizing the sliding fit between the assembly plate 11 and the sealing ring 14 and sealing groove 15 of the guide frame 9, the pipe body 10 can be easily removed for cleaning.

[0032] 2): The main body of the pipe 10 is snapped into the bracket 19 by the positioning pin 21, and the magnetic plate 20 is attracted and fixed. When disassembling, the pipe body 10 can be quickly removed by simply releasing the snapping and attraction.

[0033] 3) Start the hydraulic cylinder 5 to push the lifting plate 6 up and down along the guide column 7, and adjust the height of the guide frame 9 and the main body of the pipeline 10 to adapt to coal mine transport vehicles 3 of different heights. After the height is adjusted to the correct position, tighten the locking bolt 23 on one side of the support frame 4 to fix the guide column 7 and ensure the stability of the main body of the pipeline 10.

[0034] In summary, this coal mine safety production tunnel dust removal device achieves rapid disassembly of the main pipe body 10 through the snap-fit ​​design of the assembly plate 11 and the guide frame 9. When the nozzle 13 becomes clogged, there is no need to shut down the entire dust removal system. Simply turn the threaded column 8 to separate the guide frame 9 from the main pipe body 10. Utilizing the sliding cooperation of the sealing ring 14 and sealing groove 15 of the assembly plate 11 and the guide frame 9, the main pipe body 10 can be easily removed for cleaning. At the same time, the main pipe body 10 is snapped into the bracket 19 by the positioning pin 21, and the magnetic plate 20 is used for adsorption and fixation. During disassembly, simply release the snap-fit ​​and adsorption to quickly remove the main pipe body 10. This design avoids the complex disassembly process of traditional welding or bolt fixing methods, significantly shortens cleaning time, reduces equipment downtime caused by nozzle cleaning, reduces worker labor intensity, and allows for convenient operation even in confined tunnel spaces. Through the collaboration of multiple components, flexible and efficient dust removal operations are achieved. In use, the coal mine transport vehicle 3 moves on the track 2 between the two support frames 4. The hydraulic cylinder 5 is activated to push the lifting plate 6 up and down along the guide column 7, adjusting the height of the guide frame 9 and the main body of the pipe 10 to adapt to coal mine transport vehicles 3 of different heights. After the height is adjusted, the locking bolt 23 on one side of the support frame 4 is tightened to fix the guide column 7, ensuring the stability of the position of the main body of the pipe 10. The water inlet pipe 16 is slidably connected to the guide sleeve 17 to ensure stable water connection during lifting. Water flows through the through hole 12 into the main body of the pipe 10 and is sprayed out through the nozzle 13 for dust removal. The limiting column 18 limits the guide frame 9 to prevent it from shifting, and the bracket 19 and the magnetic plate 20 further fix the main body of the pipe 10. This design allows for flexible adjustment of the height and position of the main body of the pipe 10 according to the actual transport vehicle and dust removal needs. At the same time, it continuously and efficiently reduces dust during transportation, improving the dust removal effect. The entire operation process is simple and can adapt to the complex and ever-changing working environment of coal mine tunnels.
