Description

Technical Field

[0001] This utility model belongs to the field of mine dust control, specifically relating to a combined dust removal mechanism for a dry dust collector used in mines. Background Technology

[0002] In coal production, dust generated during mining, tunneling, and development operations is one of the core issues threatening safe production and occupational health. The importance of dust control is multifaceted: First, dust directly harms miners' health; long-term inhalation of high concentrations of coal dust can lead to pneumoconiosis, seriously threatening workers' occupational safety. Second, dust poses an explosion risk; when the concentration of coal dust in the air reaches its explosive limit, it can ignite upon contact with an open flame, potentially causing major safety accidents, resulting in casualties and equipment damage. Among dust control technologies, dry dust collectors stand out due to their high dust removal efficiency, zero water consumption, and flexible layout.

[0003] Mining cartridge dry dust collectors use pleated filter cartridges as the filter medium. Over time, a large amount of coal dust accumulates on the surface of the cartridges, increasing the dust collector's resistance, reducing airflow, and decreasing dust removal efficiency, necessitating cartridge cleaning. Common cleaning methods include pulse cleaning, reverse-air cleaning, and vibration cleaning. In cartridge dry dust collectors, pulse cleaning is most commonly used. Properly tuned parameters and well-designed nozzles allow for uniform and efficient cleaning of the dry dust-collecting cartridges. However, in tunneling and development work areas, the dust has a high moisture content, and the dust on the cartridge surface often adheres in the form of a powder cake. In this case, the performance of pulse cleaning is limited. Traditional motor-driven vibration cleaning structures often use a motor to drive an eccentric turntable to generate vibration. Given the large number of filter cartridges and the compact space design of mining dust collectors, arranging the motor vibration structure is difficult, making it almost impossible to achieve vibration cleaning without disassembling the machine. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model discloses a combined dust removal mechanism for a mining dry dust collector. This utility model uses a pneumatic vibration pump to achieve efficient dust removal technology for both agglomerated dust and dispersed dust particles by combining vibration dust removal and pulse dust removal. It does not require disassembly and improves the performance and service life of the mining dry dust collector.

[0005] To achieve the above objectives, the present invention specifically discloses the following solution:

[0006] A combined dust removal mechanism for a mining dry dust collector includes a complete dust collector unit. The dust collector unit has a dust collector inlet and a dust collector outlet at both ends. The interior of the dust collector unit includes a filter cartridge mounting plate, a pressure supply mechanism, a pneumatic pulse valve, a pulse jet pipe, and a pneumatic vibration pump. The pneumatic vibration pump is mounted on the filter cartridge mounting plate and is connected to the pressure supply mechanism. The pneumatic pulse valve is located on the pressure supply mechanism, and the pulse jet pipe is located on the pneumatic pulse valve.

[0007] Furthermore, the pressure supply mechanism includes a high-pressure air tank and a high-pressure air distribution tank, the high-pressure air tank and the high-pressure air distribution tank are connected together, and the high-pressure air distribution tank is connected to a pneumatic pulse valve and a pneumatic vibration pump respectively.

[0008] Furthermore, it also includes a mining quick-connect plug, wherein the pneumatic pulse valve is installed on the high-pressure air distribution manifold using a mining quick-connect plug.

[0009] Furthermore, it also includes a two-position three-way pneumatic normally closed valve, which is connected to the pipeline between the high-pressure air distribution manifold and the pneumatic vibration pump.

[0010] Furthermore, it also includes a two-position two-way solenoid valve, which is electrically connected to the pneumatic pulse valve and is used to control the opening and closing of the pneumatic pulse valve.

[0011] Furthermore, the top of the dust collector is provided with a dust collector cover plate for maintenance of the entire dust collector.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention uses a pneumatic vibration pump as the vibration source, reducing its volume so that the pumps can be distributed across the filter cartridge mounting plate. This achieves vibration-based dust removal in mining dust collectors without disassembly, ensuring the performance of vibration cleaning. By combining vibration cleaning and pulse cleaning, it achieves highly efficient cleaning of both agglomerated and dispersed dust particles, thereby improving the performance and service life of mining dry dust collectors. This invention reduces the frequency of disassembly and cleaning by improving cleaning performance, reducing the labor intensity of miners, improving the efficiency of dust control in coal mine production sites, protecting miners' occupational health, and effectively improving the economic and social benefits of coal mines.

Detailed Implementation

[0018] 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.

[0019] Example 1

[0020] like Figure 1-3 As shown, this embodiment discloses a combined dust removal mechanism for a mining dry dust collector, including a dust collector unit 2. The top of the dust collector unit 2 is provided with a dust collector cover plate 3 for maintenance of the dust collector unit 2. The dust collector unit 2 is provided with a dust collector inlet 1 and a dust collector outlet 7 at both ends. The dust collector unit 2 is provided with a filter cartridge mounting plate 4, a pressure supply mechanism, a pneumatic pulse valve 8, a pulse jet pipe 5, and a pneumatic vibration pump 10 inside. The filter cartridge mounting plate 4 is responsible for fixing the dust collector filter cartridges and the pressure supply mechanism. The pneumatic vibration pump 10 is installed on the filter cartridge mounting plate 4 with an anti-loosening nut and serves as a vibration source to output power. The pneumatic vibration pump 10 is connected to the pressure supply mechanism. The pneumatic pulse valve 8 is provided on the pressure supply mechanism, and the pulse jet pipe 5 is provided on the pneumatic pulse valve 8, responsible for evenly distributing the dust removal pulses to each filter cartridge.

[0021] Specifically, the pressure supply mechanism includes a high-pressure air tank 6 and a high-pressure air distribution tank 9. The high-pressure air tank 6 is responsible for storing high-pressure gas and providing power for pulse jet blowing. The high-pressure air tank 6 is connected to the high-pressure air distribution tank 9 and is filled with gas through an air filling pipe. The high-pressure air distribution tank 9 serves as a compressed gas buffer tank and is connected to the pneumatic pulse valve 8 and the pneumatic vibration pump 10 respectively.

[0022] As a preferred embodiment of this utility model, it also includes a mining quick-connect plug, wherein the pneumatic pulse valve 8 is installed on the high-pressure air distribution manifold 9 using a mining quick-connect plug.

[0023] As a preferred embodiment of the present invention, it also includes a two-position three-way pneumatic normally closed valve 12, which is connected to the pipeline between the high-pressure air distribution manifold 9 and the pneumatic vibration pump 10, and is responsible for controlling the operation of the pneumatic vibration pump 10.

[0024] As a preferred embodiment of the present invention, it also includes a two-position two-way solenoid valve 11, which is electrically connected to the pneumatic pulse valve 8 and is used to control the opening and closing of the pneumatic pulse valve 8.

[0025] The method of using this utility model is as follows:

[0026] Compressed air from the mine is used to inflate the high-pressure air tank 6, which in turn inflates the high-pressure air distribution tank 9, providing a power source for the pneumatic pulse valve 8 and the pneumatic vibration pump 10. During the dust removal operation, the two-position three-way pneumatic normally closed valve 12 is manually operated to start the pneumatic vibration pump 10. After several seconds, the valve is closed. Then, the corresponding two-position two-way solenoid valve 11 is manually operated to start the pneumatic pulse valve 8, achieving a single vibration-pulse combined dust removal operation.

[0027] The working principle of this utility model is as follows:

[0028] Compressed gas drives a pneumatic vibration pump 10, providing transverse and longitudinal vibration waves. When the vibration waves are transmitted to the filter cartridge, they generate lateral and longitudinal acceleration within the cartridge, breaking down the bonds between agglomerated dust particles and making them easier to dislodge by pulse cleaning. A subsequent pulse cleaning is performed by controlling a pneumatic pulse valve 8, using high-pressure pulses to eject the loosened dust particles, achieving a highly efficient and uniform vibration-pulse combined cleaning process.

[0029] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
