Description

Technical Field

[0001] This utility model relates to the field of gas control technology, specifically a gas control device for the upper corner. Background Technology

[0002] The term "upper corner" is a mining term referring to the triangular area near the top of the return airway and the edge of the goaf. The corner refers to a location with poor ventilation, high temperature and humidity, and a tendency to accumulate methane released from the goaf and the coal face during mining. The high methane concentration makes it a key area for methane control in the working face. Coal deposits are layered, widely distributed, and have large reserves. The coal is brittle and easily cut and broken, and mining is often accompanied by threats from water, fire, and methane. Compared to other mineral deposits, coal mining technology has some different characteristics. Mining methods are divided into open-pit mining and underground mining, usually using mechanized methods, with a few using hydraulic mining.

[0003] Patent CN111894654B discloses a device for controlling methane in the upper corner of a coal mine, comprising a box body, a bottom plate fixedly connected to the bottom of the box body, rollers fixedly connected to the four corners of the bottom of the bottom plate, a positioning plate fixedly connected to the side of the box body, a handle fixedly connected to the side of the positioning plate, a support column fixedly connected to the upper surface of the box body, a positioning bolt threaded to the side of the support column, a rotating column inserted into the upper surface of the support column, an annular groove formed on the side of the rotating column, an arc-shaped cover plate fixedly connected to the upper surface of the rotating column, a filter screen plate provided on the side of the box body away from the handle, a clamping plate fixedly connected to the inner wall of the box body, a connecting block fixedly connected to the side of the clamping plate, and a protective cover fixedly connected to the side of the connecting block.

[0004] Currently, traditional upper corner gas control devices, when in actual use, are affected by the negative pressure of ventilation in the upper corner, where gas gushing from the goaf and gas escaping from the coal face easily converge, resulting in a high gas concentration in the upper corner. Common treatment methods are to directly use high-level drilling, high-level roadways, and buried pipes for extraction. Since the position of the coal mining face is changing, it needs to be gradually advanced. However, common extraction methods are time-consuming, labor-intensive, and inconvenient to disassemble and install, reducing production efficiency. Furthermore, since the gas carries dust from the coal mine, it is inconvenient for people to utilize and treat the gas in the later stages. Utility Model Content

[0005] The purpose of this utility model is to provide a gas control device for the upper corner, in order to solve the problem mentioned in the background art that, in actual use, the upper corner is affected by the negative pressure of ventilation, and the gas gushing from the goaf and the gas escaping from the coal face easily converge here, resulting in a high gas concentration in the upper corner. The common treatment method is to directly use high-level drilling, high-level roadway and buried pipe for extraction. Since the position of the coal mining face is changing, it needs to be gradually advanced. However, the common extraction methods are time-consuming, labor-intensive and inconvenient to disassemble and assemble, which reduces production efficiency. Since the gas carries dust from the coal mine, it is inconvenient for people to use and treat the gas in the later stage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gas control device for upper corners, comprising a housing, an air inlet pipe provided on one side of the housing, an opening provided on the inner wall of the air inlet pipe, a fixing mechanism detachably connected to the outer wall of the air inlet pipe, a filter mechanism bolted to one side of the housing, an air outlet pipe fixedly connected to the other side of the housing, and a fan fixedly connected to one side of the inner top wall of the housing;

[0007] The fixing mechanism includes a fixing frame, the inner wall of which is in close contact with the outer wall of the air intake pipe. A fixing plate is provided at the lower end of the fixing frame, and bolts are provided on both sides of the lower end of the fixing plate. A connecting plate is welded to the upper end of the fixing frame, and guide rods are fixedly connected to both sides of the upper end of the connecting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The fixed mechanism ensures the equipment is securely installed in the designated location. Anchor bolts are used to fix the mounting plate to the installation surface, resulting in higher strength and greater reliability.

Simultaneously, rotating the rotating ring drives the screw to rotate within the sleeve, allowing the guide tube to slide on the guide rod. This allows adjustment of the support plate height according to actual needs, further enhancing the device's flexibility and practicality. Furthermore, the inner wall of the fixed frame is tightly fitted to the outer wall of the air inlet pipe, and the inner dimensions of the fixed frame match the outer dimensions of the air inlet pipe, tightly encasing both the inlet and outlet pipes. This prevents the inlet and outlet pipes from falling off or loosening during use, ensuring the normal operation of the device.

[0016] 2. The filtration mechanism effectively filters and adsorbs dust and impurities in the gas, improving its purity and facilitating its subsequent utilization and treatment. Furthermore, the filter box, with its baffles, rubber rings, fixing blocks, rotating plates, and connectors, allows for quick installation and disassembly, making it easy to clean or replace the filter and adsorption plates inside. This further enhances the device's practicality and convenience. Additionally, the filter and adsorption plates can filter and adsorb large and small particles of impurities in the gas respectively, improving the filtration effect. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 and Figure 4 This utility model provides a technical solution: a gas control device for upper corners, including a housing 1, an air inlet pipe 2 on one side of the housing 1, an opening 3 on the inner wall of the air inlet pipe 2, a fixing mechanism 4 detachably connected to the outer wall of the air inlet pipe 2, a filter mechanism 5 bolted to one side of the housing 1, an air outlet pipe 6 fixedly connected to the other side of the housing 1, and a fan 7 fixedly connected to one side of the inner top wall of the housing 1. The fixing mechanism 4 includes a fixing frame 41, the inner wall of the fixing frame 41 being tightly attached to the outer wall of the air inlet pipe 2, and a fixing plate 42 provided at the lower end of the fixing frame 41. Bolts 43 are provided on both sides of the lower end of the fixing plate 42. A connecting plate 44 is welded to the upper end of the fixing frame 41. Guide rods 45 are fixed to both sides of the upper end of the connecting plate 44. A guide tube 46 is slidably connected to the outer wall of the guide rod 45. A support plate 47 is fixed to the upper end of the guide tube 46. A sleeve 48 is fixed to the middle of the lower end of the support plate 47. A screw 49 is threaded to the inner wall of the sleeve 48. A rotating ring 410 is fixed to the middle of the screw 49. One side of the air inlet pipe 2 is fixed to one side of the box 1. The outer wall of the opening 3 is connected to the inner wall of the air inlet pipe 2 through the opening.

[0024] The inlet pipe 2 and outlet pipe 6 are fixedly connected to the housing 1 by welding. The inlet pipe 2 and outlet pipe 6 are configured with connecting flanges. When it is necessary to connect the gas extraction pipe, the gas extraction pipe can be connected to the inlet pipe 3 or outlet pipe 6 using bolts. Because coal is mined, and each bit of coal mined reduces the available coal reserves, the working face position changes and gradually advances forward, and the upper angle also changes accordingly. Some coal mine working faces need to advance tens of meters per day, so the device needs to be installed relatively far in front of the working face. The gas extraction pipe is connected to the gas extraction container, with its inlet located at the upper corner and typically inserted two meters deep. The gas extraction pipe is usually made of sheet metal or steel. Additionally, a high-efficiency filter 5 is bolted to the other side of the container 1 to ensure the purity of the gas during processing. A gas outlet pipe 6 is securely connected to the opposite side of the container 1 to discharge the treated gas. A fan 7 is stably installed on one side of the inner top wall of the container 1 to provide the necessary gas flow power. The inner wall of the fixed frame 41 fits tightly against the outer wall of the intake pipe 2 to ensure a stable connection. A fixing plate 42 is provided at the lower end of the fixed frame 41, with a bolt 43 on each side of the lower end of the fixing plate 42 for further fixing and adjustment. A connecting plate 44 is welded to the upper end of the fixed frame 41. Guide rods 45 are securely connected to both sides of the upper end of the connecting plate 44. The outer wall of the guide rods 45 is connected to the duct 46 via a sliding connection. A support plate 47 is fixed to the upper end of the duct 46. A sleeve 48 is firmly connected to the lower middle part of 47. The inner wall of the sleeve 48 is connected to the screw 49 by a threaded connection. A rotating ring 410 is fixed in the middle of the screw 49 for easy adjustment and operation. One side of the air inlet pipe 2 is fixed to one side of the housing 1 by a strong connection. The outer wall of the opening 3 is connected to the inner wall of the air inlet pipe 2 through the opening, ensuring smooth and efficient gas flow. This structural design enables the device to perform excellently in the process of gas control.

[0025] Please see Figure 2 In order to quickly install and fix the air inlet pipe 2 and the air outlet pipe 6 on the housing 1, the lower end of the fixing frame 41 is bolted to the upper end of the fixing plate 42, and the two sides of the lower end of the fixing plate 42 are threaded to the outer wall of the bolt 43. The inner dimensions of the fixing frame 41 are adapted to the outer dimensions of the air inlet pipe 2.

[0026] To enable rapid and efficient installation and fixing of the air inlet pipe 2 and air outlet pipe 6 on the housing 1, the lower part of the fixing frame 41 is bolted to the upper part of the fixing plate 42 to ensure a tight fit and prevent loosening. Meanwhile, the lower sides of the fixing plate 42 are threaded to the outer walls of the bolts 43. This connection method is not only strong and reliable but also allows for easy disassembly and adjustment. In addition, the inner dimensions of the fixing frame 41 are precisely set to perfectly match the outer dimensions of the air inlet pipe 2, ensuring that the air inlet pipe 2 can be smoothly inserted into the fixing frame 41 for seamless connection, thereby greatly improving installation efficiency and the stability of the overall structure.

[0027] Please see Figure 3 In order to quickly fix the filter plate 52 and the adsorption plate 53 in the housing 1, the filter mechanism 5 includes a filter box 51. The outer wall of the filter box 51 is inserted into the inner wall of one side of the housing 1. The filter plate 52 is provided on one side of the inner wall of the filter box 51. The adsorption plate 53 is provided on the inner wall of the filter box 51. A baffle 54 is fixedly connected to the front end of the filter box 51. A rubber ring 55 is glued to the rear edge of the baffle 54. A fixing block 56 is fixedly connected around the front end of the baffle 54. A rotating plate 57 is rotatably connected to the outer wall of the fixing block 56. A connector 58 is inserted into the end of the rotating plate 57 away from the fixing block 56. The inner wall of the filter box 51 is fixedly connected to the outer wall of the filter plate 52. The inner wall of the filter box 51 is fixedly connected to the outer wall of the adsorption plate 53. The outer wall of the connector 58 is threadedly connected to the front end of the housing 1 through one end of the rotating plate 57.

[0028] To ensure the rapid and secure installation and fixation of the filter plate 52 and adsorption plate 53 inside the housing 1, the outer wall of the filter housing 51 is tightly connected to one side of the inner wall of the housing 1 via an interlocking connection, ensuring the stability of the overall structure. A filter plate 52 is installed on one side of the inner wall of the filter housing 51 for efficient filtration. An adsorption plate 53 is also arranged on the inner wall of the filter housing 51 to enhance the adsorption effect. A baffle 54 is firmly fixed to the front end of the filter housing 51. A rubber ring 55 is adhesively attached to the rear edge of the baffle 54 to effectively prevent liquid or gas leakage and ensure the sealing of the filtration process. Multiple fixing blocks 56 are evenly fixed around the front end of the baffle 54. The outer wall of filter box 51 is connected to a rotating plate 57 via a rotatable connection, allowing the rotating plate 57 to rotate flexibly. A connector 58 is inserted into the end of the rotating plate 57 away from the fixed block 56. The connector 58 allows its outer wall to pass through one end of the rotating plate 57 and be threadedly connected to the front side of the housing 1, thereby achieving a firm fixation between the filter box 51 and the housing 1. In addition, one side of the inner wall of the filter box 51 is tightly connected to the outer wall of the filter plate 52 via a fixed connection. Similarly, the inner wall of the filter box 51 is also fixedly connected to the outer wall of the adsorption plate 53, ensuring the stability and efficiency of the filter plate 52 and the adsorption plate 53 during the filtration process. This configuration not only improves the installation efficiency but also greatly enhances the reliability and service life of the entire filtration mechanism 5.

[0029] Working Principle: During operation, the device is moved to the designated location, and the blower 7 is started. The blower 7 generates suction, allowing the coal mine gas to enter the housing 1 through the inlet pipe 2. After filtration and adsorption by the filter mechanism 5, the clean gas is discharged through the outlet pipe 6 for subsequent use. When it is necessary to install or remove the inlet pipe 2, simply rotate the rotating ring 410, which drives the screw 49 to rotate within the sleeve 48, thereby causing the support plate 47 and the guide tube 46 to slide on the guide rod 45. Adjust the height of the guide tube 46, and then insert the inlet pipe 2 into the fixing frame 41. Connect the fixing plate 42 to the wall or other fixed structure of the coal mine using bolts 43, thus achieving quick installation of the inlet pipe 2. When it is necessary to remove, simply rotate the rotating ring 410 in the opposite direction, adjust the height of the guide tube 46 to separate the inlet pipe 2 from the fixing frame 41, and then unscrew the bolts 43. When it is necessary to replace or clean the filter plate 52 and the adsorption plate 53, simply... Unscrew connector 58 to separate rotating plate 57 from housing 1. Then rotate rotating plate 57 to loosen the connection between fixing block 56 and rotating plate 57, allowing baffle 54 and filter box 51 to be removed from housing 1. Then replace or clean filter plate 52 and adsorption plate 53. After replacement or cleaning, reinsert filter box 51 into housing 1 and fix it with rotating plate 57 and connector 58. The fixing mechanism 4 and filtration mechanism 5 not only enable quick installation and removal of inlet pipe 2 and outlet pipe 6, but also improve the filtration and adsorption efficiency of gas, making the device more convenient and efficient to use. At the same time, the detachable design of filter mechanism 5 and adsorption plate 53 facilitates the user's later maintenance and cleaning work, extending the service life of the device. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
