Description

Technical Field

[0001] This invention relates to the field of environmental protection equipment technology in mining, specifically to a dust removal device for environmental protection during mining operations. Background Technology

[0002] During mining operations, blasting, excavation, and other activities generate large amounts of dust. This dust not only pollutes the working environment and harms the respiratory health of workers, but also poses safety hazards such as dust explosions. Therefore, efficient dust removal devices are crucial equipment for ensuring safe production and environmental protection requirements in mining operations. Currently, the most widely used dust removal devices in the industry are bag filters. These filters use cloth bags to filter dust-laden gas, causing the dust to adhere to the surface of the bags while clean gas passes through and is discharged. They feature high filtration accuracy and wide applicability.

[0003] However, existing bag filter dust collectors suffer from a significant technical drawback in actual operation: poor continuity of dust collection operations, impacting construction efficiency. Traditional bag filter dust collectors typically employ a single-chamber structure. When the dust adhering to the surface of the bags reaches a certain amount, the bags must be cleaned to maintain filtration effectiveness. However, current cleaning methods usually require shutdown, meaning the supply of dust-laden gas to the dust collector is paused, and dust is removed from the bag surface through backflushing, vibration, or other methods. Dust collection can only resume after cleaning is complete. This shutdown-for-cleaning mode forces the interruption of dust collection operations in mining. Especially in large-scale mining operations, frequent shutdowns not only severely reduce overall construction efficiency but can also hinder the normal progress of the work face due to dust accumulation.

[0004] While some improved multi-chamber dust collectors attempt to achieve continuous dust removal through alternating operation of multiple chambers, the lack of a reasonable airflow distribution and cross-chamber utilization mechanism means that when one chamber is being cleaned, the clean gas in the other chambers cannot efficiently provide a backflushing air source for the cleaned chamber. This still necessitates reliance on external air sources or partial shutdowns for adjustments, failing to fundamentally solve the problem of interrupted dust removal operations. Therefore, developing an environmentally friendly dust removal device for mining construction environments that can complete bag cleaning without shutdown and ensure continuous dust removal operations has become a pressing technical challenge for the industry.

[0007] The second partition plate is detachably equipped with multiple bag frames, and each bag frame has an air jet frame on its inner side.

[0008] Multiple main air pipes are fixedly installed on the top cover. One end of each main air pipe is fixedly connected to the jet frame, and the other end of each main air pipe is connected to the interior of multiple clean air chambers, excluding the jet frame connected to it. A third valve is fixedly installed on each main air pipe.

[0009] Preferably, the jet frame includes an exhaust ring, a connecting pipe, an L-pipe, and an air delivery pipe assembly;

[0010] The air outlet rings are provided in multiple and equally spaced arrangement along the height of the bag frame. Multiple air outlets are equally spaced along the circumference of the air outlet rings. Adjacent air outlet rings are connected by multiple connecting pipes. The L-tube is fixedly connected to the uppermost air outlet ring, and the top end of the L-tube is fixedly connected to the air delivery pipe assembly.

[0011] Preferably, the air supply pipe assembly includes a sleeve, an inner pipe, and a connecting pipe; the sleeve is installed on the top cover, one end of the inner pipe is inserted into the inside of the sleeve and slidably connected to the sleeve, and the connecting pipe is fixedly connected to one end of the main air pipe and communicates with the inside of the sleeve.

[0012] An electric telescopic rod is fixedly installed on the top cover, and a U-shaped frame is installed on the bottom end of the inner tube. The movable end of the electric telescopic rod is fixedly connected to the U-shaped frame.

[0013] Preferably, the sleeve is rotatably mounted on the top cover, and the connecting pipe is rotatably connected to the top end of the sleeve;

[0014] An adapter plate is rotatably mounted on the bottom end of the inner tube, and a rack is fixedly mounted on the adapter plate. A plug rod is fixedly mounted on the lower surface of the top cover. The bottom end of the plug rod is inserted into the rack and slidably connected to the rack. A mounting bracket is fixedly mounted on the lower surface of the top cover. A gear is rotatably mounted on the mounting bracket. A driving bevel gear is fixedly mounted on the shaft of the gear. A driven bevel gear is rotatably mounted on the mounting bracket. The driving bevel gear and the driven bevel gear are in a meshing state. A pulley is fixedly mounted on the driven bevel gear.

[0015] Preferably, the outer side of the bag frame is provided with multiple mounting rings, which are evenly distributed along the height direction of the bag frame.

[0017] Compared with the prior art, the present invention provides an environmentally friendly dust removal device for mining construction, which has the following beneficial effects:

[0018] 1. By using multiple filter bags to filter dust-laden gas in tandem, and with the guide bucket and threaded connection to the collection tank, dust can be quickly collected to avoid secondary dust generation; the continuous dust removal design reduces the gaps in dust emission, and the clean gas is discharged after filtration, effectively improving the mining construction environment, reducing the impact of dust on the surrounding ecology and personnel health, and meeting the requirements of environmentally friendly construction.

[0019] 2. The system adopts a multi-chamber alternating dust removal mode. During dust removal, only the first valve of the chamber to be cleaned is closed, and the dust supply pipe continuously delivers dust-laden gas to other chambers. At the same time, clean gas from non-dust removal chambers is used for cross-chamber backflushing. Bag cleaning can be completed without stopping the machine, avoiding the construction interruption caused by traditional shutdown dust removal, and improving the continuity and efficiency of the overall mining operation.

[0020] 3. The jet frame is driven by an electric telescopic rod to achieve a combination of lifting and rotating motion. The air outlets of the multiple air rings spray airflow from different heights and angles to eliminate dead corners in dust removal. Combined with the mechanical cleaning of the outer cleaning brush, it forms a synergistic effect of "airflow impact + physical friction" on strongly adhered dust, resulting in better dust removal effect and reducing the frequency of bag clogging and replacement.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] Please combine Figures 1 to 8 As shown, this invention discloses an environmentally friendly dust removal device for mining construction, aiming to solve the problems of low dust removal efficiency, inconvenient bag cleaning, and poor continuity of existing dust removal devices for mining construction. The invention will be further described in detail below with reference to specific embodiments.

[0041] Example 1

[0042] The environmental protection dust removal device for mining construction in this embodiment includes a dust removal box 10. Multiple first partition plates 11 are fixedly installed inside the dust removal box 10, dividing the interior of the dust removal box 10 into multiple independent dust removal chambers 111. A second partition plate 12 is fixedly installed in each dust removal chamber 111. A clean air chamber 121 is formed above the second partition plate 12. Dust-laden gas enters 121 after being filtered by a cloth bag.

[0043] A top cover 15 is detachably installed on the top of the dust collector 10. New filter bags can be easily replaced by removing the top cover 15. The top cover 15 is installed on the top of the dust collector 10 using multiple bolts. Multiple exhaust ports 16 are fixedly installed on the top cover 15, each exhaust port 16 corresponding to a clean air chamber 121. A second valve 161 is fixedly installed on each exhaust port 16 to control the discharge of clean gas from each clean air chamber.

[0044] A dust supply pipe 14 is fixedly installed on the outside of the dust collection box 10. The dust supply pipe 14 is connected to multiple dust collection chambers 111 through multiple connectors 141. Each connector 141 is fixedly installed with a first valve 142, which can independently control the flow of dust-laden gas to each dust collection chamber 111. Multiple bag frames are detachably installed on the second partition plate 12. Each bag frame has an air jet frame on its inner side. The filter bags are fitted over the outside of the bag frames to filter the dust-laden gas.

[0045] Multiple main air pipes 30 are fixedly installed on the top cover 15. One end of the main air pipe 30 is fixedly connected to the jet frame, and the other end of the main air pipe 30 is connected to the interior of multiple clean air chambers 121, except for the clean air chamber 121 corresponding to the jet frame connected to it. Each main air pipe 30 is fixedly installed with a third valve 31 to realize cross-chamber utilization of clean gas.

[0046] During dust removal, the filter bags in different dust removal chambers 111 are removed sequentially to ensure the continuity of dust removal for the entire equipment. When removing dust from the filter bags in one of the dust removal chambers 111, the second valve 161 on the exhaust port 16 connected to the clean air chamber 121 that is not undergoing filter bag removal is closed, preventing the clean gas from being directly discharged; the second valve 161 on the exhaust port 16 connected to the clean air chamber 121 that is undergoing filter bag removal is opened to discharge the final clean gas.

[0047] At the same time, the first valve 142 on the connector 141 connected to the dust removal chamber 111 for bag dust removal is closed, stopping the supply of dust-laden gas to the dust removal chamber 111; the dust supply pipe 14 continues to supply dust-laden gas to the dust removal chamber 111 for which bag dust removal is not performed, and after the dust-laden gas is filtered by the bag, the clean gas enters the corresponding clean air chamber 121.

[0048] Open the third valve 31 on one of the main air pipes 30. The air inlet of the main air pipe 30 is connected to the clean air chamber 121, which is not used for bag dust collection. Clean gas enters the main air pipe 30, then enters the jet generator, and is finally sprayed onto the inner surface of the filter bag by the jet generator, causing the dust adhering to the outer surface of the filter bag to fall off under the impact of the airflow. A guide hopper 13 is fixedly installed at the bottom of the dust collection box 10. A collection trough is threadedly connected to the bottom of the guide hopper 13, and the collection trough collects the dust that is knocked off by the airflow.

[0049] By using multiple dust removal chambers 111 for alternating dust removal and utilizing clean gas across chambers, the dust removal process is made continuous, avoiding the efficiency loss caused by the shutdown of traditional equipment for cleaning the filter bags.

[0050] Example 2

[0051] The jet frame includes an exhaust ring 20, a connecting pipe 21, an L-pipe 24, and an air supply pipe assembly. The exhaust ring 20 has multiple air outlets 201 that are evenly distributed along the height direction of the bag frame. In order to achieve comprehensive dust removal along the height direction of the bag, the exhaust ring 20 has multiple air outlets 201 that are evenly spaced along its circumference. Adjacent exhaust rings 20 are connected by multiple connecting pipes 21. The L-pipe 24 is fixedly connected to the uppermost exhaust ring 20, and the top end of the L-pipe 24 is fixedly connected to the air supply pipe assembly.

[0052] The air supply pipe assembly includes a sleeve 22, an inner pipe 23, and a connecting pipe 25. The sleeve 22 is rotatably mounted on the top cover 15, and the connecting pipe 25 is rotatably connected to the top end of the sleeve 22 to ensure that the position of the connecting pipe 25 is fixed when the sleeve 22 rotates.

[0053] One end of the inner tube 23 is inserted into the interior of the sleeve 22 and slidably connected to it. A track bar 231 is fixedly installed on the outer surface of the inner tube 23, and a track groove 221 for the track bar 231 to slide on the inner surface of the sleeve 22. The connecting pipe 25 is fixedly connected to one end of the main air pipe 30, and the connecting pipe 25 is connected to the interior of the sleeve 22. An electric telescopic rod 50 is fixedly installed on the top cover 15. A transition plate 232 is rotatably installed on the bottom end of the inner tube 23. A U-shaped frame 51 is fixedly installed on the transition plate 232. The movable end of the electric telescopic rod 50 is fixedly connected to the U-shaped frame 51 for driving the inner tube 23 to move up and down.

[0054] A rack 60 is fixedly mounted on the adapter plate 232, and a rod 66 is fixedly mounted on the lower surface of the top cover 15. The bottom end of the rod 66 is inserted into the rack 60 and slidably connected to it, thus guiding and limiting the movement of the rack 60. A mounting bracket 65 is fixedly mounted on the lower surface of the top cover 15, and a gear 61 is rotatably mounted on the mounting bracket 65. The gear 61 meshes with the rack 60.

[0055] A driving bevel gear 62 is fixedly mounted on the shaft of gear 61, and a driven bevel gear 63 is rotatably mounted on the mounting bracket 65. The driving bevel gear 62 and the driven bevel gear 63 are in a meshing state. A pulley is fixedly mounted on the driven bevel gear 63, and a transmission belt 64 is sleeved on the pulley. One end of the transmission belt 64 is sleeved on the sleeve 22, forming a complete transmission chain.

[0056] Based on the working process of Embodiment 1, in this embodiment, when the movable end of the electric telescopic rod 50 extends and retracts, it drives the U-shaped frame 51 and the inner tube 23 to rise and fall synchronously, thereby causing multiple air outlet rings 20 to rise and fall. At the same time, the rack 60 rises or falls synchronously with the inner tube 23. Since the rack 60 meshes with the gear 61, the linear motion of the rack 60 is converted into the rotational motion of the gear 61.

[0057] The rotation of gear 61 drives the rotation of the driving bevel gear 62, which in turn drives the meshing driven bevel gear 63 to rotate. The pulley on the driven bevel gear 63 drives the sleeve 22 to rotate via the transmission belt 64. When the sleeve 22 rotates, the sliding fit between the inner tube 23 and the sleeve 22 drives the inner tube 23 and multiple air outlet rings 20 to rotate synchronously.

[0058] Therefore, the air outlet ring 20 can simultaneously rise, fall, and rotate, allowing the gas ejected from the air outlet 201 to contact the inner surface of the filter bag from different heights and angles. This avoids the dead zones in cleaning that exist in traditional fixed air jet methods, significantly improving the comprehensiveness and thoroughness of filter bag cleaning.

[0059] Example 3

[0060] Based on the structure of Embodiment 2, this embodiment provides multiple mounting rings 40 on the outside of the bag frame. The multiple mounting rings 40 are evenly distributed in the height direction of the bag frame. A cleaning brush 41 is fixedly installed on the inner surface of each mounting ring 40, and the cleaning brush 41 is in contact with the outer surface of the bag.

[0061] Multiple mounting rings 40 are fixedly connected by connecting strips 42 to form an integral cleaning frame. Connecting strips 43 are fixedly installed on the connecting strips 42. The top end of the connecting strips 43 is detachably connected to the U-shaped frame 51. An assembly block is set between the top end of the connecting strips 43 and the U-shaped frame 51. The two ends of the assembly block are connected to the connecting strips 43 and the U-shaped frame 51 by bolts and nuts, respectively. A sealed window is detachably installed on the dust collection box 10 by bolts. Each clean air chamber 121 corresponds to a sealed window. After the sealed window is removed, the bolts on the assembly block are removed, and the top cover 15 is removed from the top of the dust collection box 10 to replace the new filter bag.

[0062] During the operation of Embodiment 2, when the movable end of the electric telescopic rod 50 extends or retracts, driving the U-shaped frame 51 to move, it not only drives the jet frame to lift and rotate for dust removal, but also drives the connecting strip 42 and multiple mounting rings 40 to move up and down synchronously through the connecting strip 43.

[0063] When the mounting ring 40 moves, the cleaning brush 41 on its inner side slides relative to the outer surface of the bag, mechanically cleaning the dust adhering to the outer surface of the bag. This mechanical cleaning works synergistically with the airflow impact cleaning of the jet frame. For some strongly adhered dust, the physical friction of the cleaning brush 41 can peel it off, and then the airflow can blow it off, greatly improving the dust removal effect, extending the service life of the bag, and reducing the frequency of bag replacement.

[0064] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
