Description

Technical Field

[0001] The utility model relates to the technical field of dust filtering equipment, in particular to a ventilation dust filtering device for mining. Background Art

[0002] Mine ventilation is a key link in ensuring the safety of underground mine operations. In mines, the mining of rocks and coal seams will produce a large amount of dust, harmful gases and heat, which seriously threaten the life safety and health of miners.

[0003] Therefore, it is necessary to use special ventilation equipment and facilities to deliver fresh air into the mine, and at the same time dilute and remove the polluted air in the mine, which can not only effectively improve the air quality in the mine, but also reduce the concentration of dust and harmful gases. When circulating the air in the mine, air ducts are used to connect multiple ventilation equipment to cope with the problem of deep mines. However, when the air in the mine is circulated through the ventilation equipment and the air duct, the dust in the mine will enter the air duct through the ventilation equipment, which will cause some dust to accumulate in the air duct, thereby causing dust coverage on the ventilation equipment in the mine, thereby affecting the normal operation of the ventilation equipment in the mine. At the same time, when the air discharged through the air duct contains a large amount of dust, it will also affect the air outside the mine. The filtering equipment creates a certain filtering pressure. At the same time, as disclosed in the Chinese utility model patent with the existing announcement number CN214437420U: a mine ventilation dust filtering device, after filtering the air in the mine, can make the driving motor rotate, and drive the cleaning brush to brush back and forth through the crankshaft, and at the same time, the crankshaft drives the driven gear to rotate through the driving gear, and the driven gear is engaged with a number of transmission teeth to drive the lifting slide rail to slide up and down, so that the cleaning brush can brush horizontally and slide up and down at the same time, and the surface of the filter screen is completely cleaned. However, after intercepting and filtering the dust in the mine, when the dust is cleaned by the cleaning brush, the cleaned dust will still fall into the mine or the air duct, thereby failing to realize the centralized collection and treatment of the cleaned dust.

[0028] like Figure 1-Figure 3 As shown, a gear 15 is fixedly installed at the output end of the motor 3. A gear 15 is arranged at the output end of the gear 15 to provide power conditions for the rotation of the mounting ring 7. A dust guide groove 12 is provided on the filter valve body 1 above the dust removal box 10. A dust removal drawer 11 is inserted in the dust removal box 10. By arranging the dust removal box 10 and the dust removal drawer 11 at the bottom of the filter valve body 1, the cleaned dust can be temporarily collected and stored when the filter is cleaned.

[0029] like Figure 1-Figure 2 , Figure 5 As shown, one side of the air deflector 5 has a double-sided guide slope, one side of the brush rod 6 is fixedly installed with a plurality of bristles 16, and the side of the brush rod 6 opposite to the bristles 16 is fixedly installed with a plurality of connecting rods 17, and the connecting rods 17 are fixedly installed on one side of the air deflector 5 by screws. The air deflector 5 is installed in the filter valve body 1 and is located on one side of the dust guide groove 12. The brush rod 6 and the bristles 16 can cooperate with each other to clean the dust on the filter screen, and allow the dust to enter the dust removal drawer 11 through the dust guide groove 12.

[0030] like Figure 2-Figure 6As shown, positioning grooves 14 are provided in the filter valve body 1 at both sides of the mounting ring seat 4, and a limiting ring 22 is clamped in the positioning groove 14. A connecting through groove 13 is provided at the bottom of the mounting ring seat 4. Positioning rings 18 are fixedly installed on both sides of the mounting ring 7. A plurality of balls 19 are rotatably installed in the positioning ring 18. A plurality of slots 20 are provided on the inner side of the mounting ring 7. An annular tooth groove 21 is provided on the outer side of the mounting ring 7. The mounting ring 7 is rotatably installed in the mounting ring seat 4, and the positioning ring 18 is rotatably installed in the positioning groove 14 and is limited by the limiting ring 22. The tooth groove 21 located at the connecting through groove 13 is meshed with the gear 15. The support rod 8 is connected to the connecting ring 9, and a pad 23 is fixedly installed at one end of the support rod 8 away from the connecting ring 9, and an insert block 24 is fixedly installed at the bottom of the pad 23. One end of the support rod 8 is inserted and installed on the inner side of the mounting ring 7 through the pad 23 and fixed by screws, and the insert block 24 is inserted and installed in the corresponding slot 20. A filter is fixedly installed on one side of the connecting ring 9 and multiple support rods 8.

[0031] It should be noted that the utility model is a ventilation dust filter device for mining. When the air in the mine is circulated through the ventilation equipment and the air duct, the air in the mine discharged through the air duct will contain a large amount of dust. After the dust passes through the filter valve body 1 in the air duct, it will be intercepted and filtered by the filter on the side of the support rod 8 in the filter valve body 1. Therefore, through the arrangement of multiple filter valve bodies 1 in the entire ventilation system, the filtration pressure of the air filtration equipment placed outside the mine in the ventilation system can be effectively reduced. At the same time, the ventilation equipment located in the mine can also be effectively protected from dust reduction. When it is necessary to clean the filter on one side of the support rod 8, the air valve 2 can be started through the terminal controller to close the channel on the corresponding side of the filter valve body 1. Subsequently, The motor 3 is started, so that the output end driving gear 15 of the motor 3 rotates, and the positioning groove 14 is meshed with the tooth groove 21 on the outside of the mounting ring 7 to drive the mounting ring 7 to rotate in the mounting ring seat 4. As a result, the mounting ring 7 synchronously drives the multiple support rods 8 to rotate, and then the filter screen on one side of the support rod 8 rotates on the side of the bristles 16. With the help of the setting of the bristles 16, the dust cleaned from the filter screen can fall into the bottom of the filter valve body 1, and fall into the dust removal drawer 11 through the dust guide groove 12, so that the filter screen on one side of the support rod 8 can be cleaned and the dust can be collected. When the filter screen on one side of the support rod 8 is cleaned, the motor 3 can be turned off and the air valve 2 can be opened, so that the air duct of the corresponding section can continue to have normal air circulation exchange.
