Description
Technical Field
[0001] This utility model relates to the field of dust collectors, and in particular to a high-precision dry dust collector for mining based on a cylindrical type. Background Technology
[0002] Mining dust collectors are devices specifically designed for the mining industry to remove dust particles from the air inside mines, ensuring the health and safety of miners. These dust collectors are typically designed to be very robust and durable, able to withstand harsh working environments, and possess highly efficient dust removal capabilities, ensuring that the air quality inside the mine meets safety standards.
[0003] There is currently a Chinese patent document CN202323450514.0 describing a high-efficiency dry dust collector for coal mines. It includes a support plate with a suction port, a filter cylinder covering the suction port, a negative pressure device connected to the suction port, a bracket on the support plate, and a protective cover over the filter cylinder. A motor is mounted on the bracket and connected to a vertically aligned shaft on the filter cylinder's axis. The shaft passes through the protective cover and connects to a brush plate that contacts the filter portion of the filter cylinder. A dust suction port is located on the protective cover. The negative pressure device generates negative pressure, allowing outside air to enter the protective cover through the suction port and be filtered by the filter cylinder. The motor drives the brush plate to rotate around the filter cylinder, thus cyclically brushing away the dust adhering to the filter cylinder, avoiding the loud noise and damage to the equipment caused by vibration cleaning.
[0004] However, the above-mentioned patent has certain defects in use. Since the motor can only drive a single brush plate to rotate around the filter cylinder, the dust removal efficiency inside the dust collector cannot reach the ideal state, thus adversely affecting the dust removal efficiency.
[0005] Therefore, a high-precision cylindrical dry dust collector for mining is proposed to solve the aforementioned problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0030] Example:
[0031] Please see Figures 1-5 Based on a cylindrical high-precision dry dust collector for mining, including:
[0032] The dust collector body 1 has a tube sheet 2 inside. The upper chamber 3 is above the tube sheet 2, and the lower chamber 4 is below the tube sheet 2. Multiple bushings 8 are provided on the tube sheet 2. Each of the multiple bushings 8 is equipped with a filter device. The filter device includes a fixed shaft 9, a driven gear 10, a filter cylinder 11, a fixed groove 12, and a filter screen cylinder 13. The fixed shaft 9 is installed in the bushing 8. The driven gear 10 is fixedly connected above the fixed shaft 9 and is located above the tube sheet 2. The filter cylinder 11 is fixedly connected to the bottom of the bushing 8. The upper and lower ends of the filter cylinder 11 are fixedly connected to the fixed grooves 12. The filter screen cylinder 13 is installed in the fixed grooves 12.
[0033] The dust collector body 1 is equipped with a motor 5 at the top. The output end of the motor 5 passes through the dust collector body 1 and is connected to a rotating shaft 6. The rotating shaft 6 is located in the upper chamber 3. A transmission gear 7 is fixedly connected to the rotating shaft 6, and the transmission gear 7 meshes with the driven gear 10.
[0034] Both sides of the lower compartment 4 are fixedly connected to side plates 14. Multiple pairs of fixing devices are fixedly installed on the side plates 14. Each pair of fixing devices includes two fixing plates 15. Each fixing plate 15 is provided with a groove 16, and a cleaning device is installed in the groove 16.
[0035] In this embodiment, the dust collector body 1 is equipped with a tube sheet 2, which divides the dust collector body 1 into two parts: an upper chamber 3 above the tube sheet 2 and a lower chamber 4 below the tube sheet 2, forming an effective airflow separation area. Multiple bushings 8 are provided on the tube sheet 2 for installing a filter device. In the filter device, a driven gear 10 is provided above a fixed shaft 9, and the driven gear is located inside the upper chamber 3. A filter cylinder 11 is connected below the fixed shaft 9, and the filter cylinder 11 is located inside the lower chamber 4. The filter cylinder 11 has multiple through holes of different sizes on its wall. To achieve dust and gas separation, fixed grooves 12 are fixedly connected to the upper and lower ends of the filter cylinder 11. The filter screen cylinder 13 installed in the groove further enhances the filtration effect. A motor 5 is provided on the top of the dust collector body 1. The rotating shaft 6 at the output end of the motor 5 is connected to the transmission gear 7 in the upper chamber 3, thereby driving the driven gear 10. This enables the filter device installed in the bushing 8 to operate efficiently. In addition, the fixing device on the side plate 14 ensures the stability of the cleaning device, which facilitates regular cleaning and maintenance of the filter screen cylinder 13 and ensures the durability of the dust removal effect.
[0036] Specifically, the cleaning device includes a fixed rod 17, a thread 18, a fixed sleeve 19, and a bracket 20. The fixed rod 17 has two threads 18 on its outer wall, and a fixed sleeve 19 is fixedly connected to each of the two threads 18. The fixed sleeve 19 is installed in the groove 16. Two brackets 20 are installed at both ends of the fixed sleeve 19. A cleaning plate 21 is installed on the two brackets 20, and multiple brush heads 22 are provided on the cleaning plate 21.
[0037] In this embodiment, the fixing sleeve 19 on the thread 18 is rotated to firmly fix the fixing rod 17 in the groove 16 of the fixing plate 15. After the fixing rod 17 is fixed, the multiple brush heads 22 on the cleaning plate 21 will be in close contact with the filter cylinder 13 to perform a rotating cleaning, effectively removing accumulated dust and dirt and maintaining the filtration efficiency of the filter cylinder 13.
[0038] Specifically, an air pump 27 is connected to the upper side of one side of the dust collector body 1. Two connecting pipes 28 are installed on the air pump 27. The two connecting pipes 28 pass through the dust collector body 1 and move within the upper chamber 3. Each connecting pipe 28 is equipped with two pulse valves 26, and each pulse valve 26 is located above the fixed shaft 9.
[0039] Specifically, the pulse valve 26 works in conjunction with the air pump 27 to achieve high-pressure air pulse cleaning of the filter cartridge 11, effectively removing stubborn stains on the filter screen cartridge 13. When the pulse valve 26 is opened, the high-pressure airflow is instantly ejected and impacts the filter cartridge 11 and filter screen cartridge 13 installed below the fixed shaft 9, thereby achieving a fast and thorough cleaning effect and completing high-precision dust removal in conjunction with the cleaning device.
[0040] Specifically, a funnel 23 is installed at the bottom of the lower compartment 4, and a recycling bin 24 is installed at the bottom of the funnel 23.
[0041] In this embodiment, when the pulse valve 26 is opened, the dust impacting the filter cylinder 11 and the filter screen cylinder 13 will fall into the collection box 24 at the bottom of the funnel 23, which facilitates the centralized treatment of the dust.
[0042] Specifically, an air inlet pipe 29 is installed on one side of the dust collector body 1, and an air outlet pipe 30 is installed on the side away from the air inlet pipe 29. A centrifugal fan 31 is fixedly connected to the air outlet pipe 30. The air inlet pipe 29 passes through the dust collector body 1 and is located in the lower chamber 4, while the air outlet pipe 30 passes through the dust collector body 1 and is located in the upper chamber 3.
[0043] In this embodiment, the dust enters the lower chamber 4 through the air inlet pipe 29. Larger dust particles fall directly into the funnel 23, while smaller particles enter the filter device. After passing through the filter device, the air outlet pipe 30 in the upper chamber 3 discharges the purified air through the centrifugal fan 31, thus achieving a clean working environment.
[0044] Specifically, a support frame 25 is fixedly installed at the bottom of the dust collector body 1.
[0045] In this embodiment, the support frame 25 is located at the bottom of the dust collector body 1 and is used to support the dust collector body 1.
[0046] Specifically, the dust collector body 1 has a door 32 installed on the front, and an observation window 33 is installed inside the door 32.
[0047] In this embodiment, an observation window 33 is provided on the door 32 installed on the front of the dust collector body 1, which allows the operator to observe the internal working status in real time, adjust the cleaning device and replace the filter cylinder 13 in a timely manner, ensure the long-term stable operation of the equipment, reduce maintenance costs and improve dust removal efficiency.
[0048] The principle of this invention is as follows: Dust first enters the lower chamber 4 through the air inlet pipe 29. Larger dust particles fall directly into the funnel 23, while smaller particles enter the filtration device. Dust enters the filter cylinder 13, and even smaller dust particles enter the filter cylinder 11 for deep filtration. When dust accumulates to a certain level in the filter cylinder 11 and the filter screen, the pulse valve 26 opens, and a high-pressure airflow instantly impacts the filter cylinder 11 and the filter screen 13 installed below the fixed shaft 9. At the same time, the motor 5 drives the transmission gear 7, causing the driven gear 10 to rotate, which in turn drives the filter screen 13 inside the filter cylinder 11 to rotate. Simultaneously, in conjunction with the cleaning device installed on the side plate 14, multiple brush heads 22 on the cleaning plate 21 will closely adhere to the filter screen 13 for rotary cleaning when the filtration device rotates, effectively removing accumulated dust and dirt. After filtration is completed, clean air enters the upper chamber 3, and the air outlet pipe 30 in the upper chamber 3 discharges the purified air through the centrifugal fan 31, thus achieving a clean working environment.
[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
