Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of coal mine ventilation equipment, specifically relating to a coal mine ventilation gas and dust filtration and purification device. Background Technology
[0002] The underground mining environment in coal mines is complex. During the coal mining process, due to the occurrence conditions of the coal seam and the influence of mining technology, a large amount of methane gas and dust are generated. The main component of methane gas is methane, which is a flammable and explosive harmful gas that is prone to explosion when exposed to a source of ignition. At the same time, coal mine dust consists of solid particles generated during coal mining, including coal dust and rock dust. Dust not only pollutes the underground air environment and reduces visibility, affecting the vision and operation of workers, but long-term inhalation can also lead to occupational diseases such as pneumoconiosis, seriously endangering the health of workers. In order to ensure the safe production of coal mines, ventilation systems are an essential facility in underground coal mines. Ventilation systems maintain the safety and stability of the underground air environment by diluting and expelling methane gas and dust.
[0003] However, current gas and dust filtration and purification devices typically use filter plates to intercept and filter dust in coal mine air. Due to the large amount of dust in coal mines, the filter plates are prone to rapid saturation and require frequent replacement, causing considerable inconvenience in maintenance. Furthermore, when filtering dust in coal mine air, the purification of gas is not thorough enough, reducing the purification effect. Therefore, the applicant proposes a coal mine ventilation gas and dust filtration and purification device to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a coal mine ventilation gas and dust filtration and purification device. After filtering and intercepting dust in the coal mine air using a filter cartridge, the vibration generated during the operation of the machine body causes the filter cartridge to vibrate, which can shake off the dust accumulated on the surface of the filter cartridge, thus extending the filtration effect of the filter cartridge, reducing the replacement cycle, and bringing more convenience to maintenance. At the same time, the filtered coal mine air can enter the purification chamber for thorough purification, which can effectively improve the filtration and purification effect of coal mine air.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A coal mine ventilation gas and dust filtration and purification device includes:
[0007] A support frame and a processing mechanism mounted on the top of the support frame, as well as a filtration mechanism and a purification mechanism respectively mounted inside the processing mechanism;
[0008] The processing mechanism includes a processing box fixedly installed on the top of the support frame, and the processing box has a filtration chamber and a purification chamber respectively inside;
[0009] The filtration mechanism includes a slide rod fixedly installed on the top of the filter chamber, an mounting sleeve slidably installed between the slide rods via a slide block, a vibration spring fixedly installed between the slide block and the slide rod, and a filter cylinder threaded onto the bottom of the mounting sleeve;
[0010] The purification mechanism includes a spray pipe fixedly installed on the inner wall of the purification chamber, and the front end of the spray pipe is connected to an atomizing nozzle.
[0011] Preferably, an air inlet hood communicating with the filter chamber is fixedly installed on one side of the treatment box, and a discharge pipe communicating with the purification chamber is fixedly installed at the rear end of the treatment box.
[0012] Preferably, an exhaust pipe communicating with the purification chamber is fixedly installed on the other side of the treatment box, and an exhaust fan is fixedly installed inside the exhaust pipe.
[0013] Preferably, the front end of the processing box is hinged with a door corresponding to the filter chamber, and a collection box corresponding to the filter cartridge is placed inside the filter chamber.
[0014] Preferably, a partition is fixedly installed inside the cleanroom, and the surface of the partition is uniformly provided with diversion holes.
[0015] Preferably, the purification chamber and the filter chamber are connected to each other through an air guide hole, and a corrugated pipe is fixedly installed between the mounting sleeve and the air guide hole.
[0016] Preferably, a storage tank and a conveying pump are fixedly installed on the top of the processing box, and a conveying pipe is connected between the conveying pump and the spray pipe.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] (1) This utility model is equipped with a filter mechanism, which can filter and intercept dust in the coal mine air by using the filter cylinder. During the process, the vibration force generated by the machine body during operation can be transmitted to the mounting sleeve. By utilizing the elasticity of the vibration spring, the mounting sleeve can vibrate up and down along the slide rod, which can easily shake off the dust accumulated on the surface of the filter cylinder, extend the filtration effect of the filter cylinder, reduce the replacement cycle, and bring more convenience to maintenance.
[0019] (2) This utility model has a partition installed in the purification room, which allows the filtered coal mine air to enter the purification room. The flow holes on the partition can disperse the coal mine air and slow down its flow rate. With the help of multiple spray pipes, the coal mine air is sprayed with catalyst, which can be fully mixed with the gas in the coal mine air. Under the action of the catalyst, the combustible gases such as methane in the gas react with oxygen to produce carbon dioxide and water, thereby achieving gas purification. The purified gas can be directly discharged into the atmosphere or collected and utilized, which effectively improves the purification effect. Attached Figure Description

[0029] Example 1:
[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a coal mine ventilation gas and dust filtration and purification device includes:
[0031] The support frame 3 and the processing mechanism 1 assembled on the top of the support frame 3, and the filtration mechanism 4 and the purification mechanism 2 respectively assembled inside the processing mechanism 1;
[0032] The processing unit 1 includes a processing box 11 fixedly installed on the top of the support frame 3. The processing box 11 has a filter chamber 16 and a purification chamber 18 respectively inside.
[0033] The filter mechanism 4 includes a slide rod 44 fixedly installed on the top of the filter chamber 16, an mounting sleeve 42 slidably installed between the slide rods 44 via a slide seat 43, a vibration spring 45 fixedly installed between the slide seat 43 and the slide rods 44, and a filter cylinder 41 threadedly installed at the bottom of the mounting sleeve 42.
[0034] The purification mechanism 2 includes a spray pipe 21 fixedly installed on the inner wall of the purification chamber 18, and the front end of the spray pipe 21 is connected to an atomizing nozzle 22.
[0035] As can be seen from the above, the support frame 3 can be used to support the processing mechanism 1 during use, and the device can be placed in a suitable position in the coal mine construction area. By drawing coal mine air into the filter chamber 16, the filter cylinder 41 can intercept and filter the dust in the coal mine air. During the filtration process, the vibration force generated by the machine body can be used to make the vibration spring 45 vibrate. The elasticity of the vibration spring 45 can drive the mounting sleeve 42 to vibrate up and down along the slide rod 44, which can easily shake off the dust accumulated on the surface of the filter cylinder 41, extend the filtration effect of the filter cylinder 41, reduce the replacement cycle, and bring more convenience to maintenance. Since the mounting sleeve 42 and the filter cylinder 41 are connected by threads, the filter cylinder 41 can be disassembled and installed with the mounting sleeve 42 by rotating it, which is convenient for the periodic replacement of the filter cylinder 41.
[0036] The filtered coal mine air can enter the purification chamber 18. By delivering the catalyst required for purification to the injection pipe 21, the catalyst can be atomized and sprayed out using the atomizing nozzle 22, which can easily mix with the coal mine air. Under the action of the catalyst, the combustible gases such as methane in the gas undergo an oxidation reaction with oxygen to produce carbon dioxide and water, thereby achieving gas purification. The purified gas can be directly discharged into the atmosphere or collected and utilized, effectively improving the purification effect.
[0037] Depend on Figure 1 and Figure 3 It can be seen that an air inlet hood 15 connected to the filter chamber 16 is fixedly installed on one side of the treatment box 11, and a discharge pipe 112 connected to the purification chamber 18 is fixedly installed at the rear end of the treatment box 11.
[0038] As can be seen from the above, the air intake hood 15 can easily introduce the air in the coal mine into the filter chamber 16 for filtration, and the discharge pipe 112 can easily discharge the water generated in the purification chamber 18 during the purification process, making it convenient for recycling.
[0039] For details, please refer to Figure 1 As shown, an exhaust pipe 12 connected to the purification chamber 18 is fixedly installed on the other side of the treatment box 11, and an exhaust fan 13 is fixedly installed inside the exhaust pipe 12.
[0040] As can be seen from the above, the exhaust fan 13 can perform a suction operation, which creates a negative pressure inside the processing box 11. This allows the air intake hood 15 to generate suction, drawing air from the coal mine into the processing box 11 for filtration and purification. The purified air can then be discharged into the external environment through the exhaust pipe 12.
[0041] For details, please refer to Figure 2As shown, the front end of the processing box 11 is hinged with a box door 14 corresponding to the filter chamber 16, and the inside of the filter chamber 16 is a collection box 17 corresponding to the filter cartridge 41.
[0042] As can be seen from the above, the dust on the surface of the filter cartridge 41 is shaken off by vibration, and the dust can fall into the collection box 17 for collection. The collection box 17 can be easily taken out by opening the box door 14, which facilitates the processing of the collected dust and the replacement and maintenance of the filter cartridge 41.
[0043] Example 2:
[0044] refer to Figure 3 As shown, a partition 19 is fixedly installed inside the cleanroom 18, and diversion holes 110 are evenly opened on the surface of the partition 19.
[0045] As can be seen from the above, by allowing the filtered coal mine air to enter the purification chamber 18, the multi-layer partition 19 can intercept the coal mine air, and the diversion hole 110 can disperse the coal mine air, which can slow down the flow rate of the coal mine air and allow the coal mine air to be fully mixed with the injected catalyst, thereby improving the purification effect.
[0046] refer to Figure 3 and Figure 4 As shown, the purification chamber 18 and the filter chamber 16 are connected to each other through the air guide hole 111, and a corrugated pipe 46 is fixedly installed between the mounting sleeve 42 and the air guide hole 111.
[0047] As can be seen from the above, the filtered coal mine air can be introduced into the purification chamber 18 for purification through the air guide hole 111. The expansion and contraction characteristics of the corrugated pipe 46 can be used to prevent the mounting sleeve 42 from vibrating up and down, which brings more convenience to the user.
[0048] refer to Figure 3 and Figure 5 As shown, a storage tank 25 and a conveying pump 24 are fixedly installed on the top of the processing tank 11, and a conveying pipe 23 connects the conveying pump 24 and the spray pipe 21.
[0049] As can be seen from the above, the storage tank 25 can conveniently store the catalyst used for purifying gas, the delivery pump 24 can extract the catalyst from the storage tank 25, and the delivery pipe 23 can deliver the catalyst to the injection pipe 21, so that the catalyst can be sprayed out to purify the gas.
[0050] 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.
