Description

Technical Field

[0001] This utility model relates to the field of dust filtration, and more specifically, to a ventilation dust filtration device used in mining operations. Background Technology

[0002] In the working environment of underground mines, ventilation devices need to be installed underground to ensure the oxygen concentration of the underground air and avoid accidents. Secondly, the high concentration of dust underground not only seriously endangers human health, but also greatly reduces the visibility of the workplace, obstructing the vision of workers and seriously affecting safe production.

[0003] Dust filtration in mine ventilation commonly uses screen-type dust removal technology, but it has significant shortcomings in high-dust mining environments. When mining and blasting generate large amounts of dust, dust particles quickly adhere to the filter screen pores, causing blockages. This not only drastically increases ventilation resistance and reduces dust removal efficiency from over 90% to below 30%, but also requires frequent machine shutdowns for filter replacement. This process not only interrupts mining operations and increases manpower and maintenance costs, but also further prolongs downtime due to the confined space and inconvenient equipment disassembly and assembly in mines. Therefore, we propose a ventilation dust filtration device for mines. Utility Model Content

[0004] The purpose of this invention is to solve the problem that it is difficult to effectively filter dust by simply relying on a filter screen when the dust level is high.

[0005] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a ventilation dust filtration device for mining operations, comprising a filter box. Air boxes are provided on both the left and right sides of the filter box, and fans are provided on the upper surfaces of both air boxes. Transmission pipes are provided on the front and rear sides of the left air box. Diverter plates are fixedly connected to both the front and rear sides of the filter box, and the transmission pipes communicate with the interior of the diverter plates. An air outlet plate is fixedly connected to the bottom wall of the filter box, and the air outlet plate communicates with the interior of the diverter plates. An air outlet hole extending into the upper surface of the air outlet plate is provided. A first partition plate is fixedly connected to the bottom wall of the filter box, and the first partition plate is S-shaped. A curved baffle plate is fixedly connected to the inner wall of the filter box, and the curved baffle plate is arc-shaped. A filter assembly is provided inside the filter box.

[0006] As a preferred technical solution of this application, the filter assembly includes a second partition, which is fixedly connected to the bottom wall of the filter box. The second partition is located on the right side of the inverted plate baffle and is inclined. A spray plate is fixedly connected to the top wall of the filter box.

[0007] As a preferred technical solution of this application, the lower surface of the spray plate is provided with an atomizing nozzle, and the upper surface of the filter box is fixedly connected with a pump body.

[0008] As a preferred technical solution of this application, the output end of the pump body is connected to the interior of the spray plate, and the input end of the pump body is fixedly connected to a water pipe.

[0009] As a preferred technical solution of this application, the water pipe extends into the interior of the filter box, and an installation frame is fixedly connected to the inner wall of the filter box.

[0010] As a preferred technical solution of this application, the upper surface of the filter box is provided with an insertion groove extending into it, and a filter screen is provided inside the mounting frame.

[0011] As a preferred technical solution of this application, the upper surface of the filter screen extends to the outside of the filter box through an insertion groove, and a mounting plate is fixedly connected to the upper surface of the filter screen, and a fixing bolt is provided on the mounting plate.

[0012] As a preferred technical solution of this application, a filling block is fixedly connected to the lower surface of the mounting plate, the filling block is inserted into the insertion slot, and a dust sensor is provided on the left side of the air box, the dust sensor being electrically connected to the fan and the pump body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In the scheme of this application:

[0015] 1. The filter box can be divided into multiple areas by the setting of multiple first partitions, which makes it easier for the diversion plate to divide the air and then transmit it to the water through the air outlet plate. At the same time, the S-shaped setting of the first partition can also prolong the time that the air stays in the water flow, thereby improving the adsorption effect. When the water flow is contaminated, it can be quickly discharged and clean water is added during the discharge process to dilute the dust content in the water. When the working intensity is not high, the machine can be stopped to drain the water.

[0016] 2. The air can be filtered a second time using a spray plate and atomizing nozzles. The filter screen can further adsorb small dust particles in the air. With the insertion slot being wider than the filter screen, the inner wall of the insertion slot will not scrape the dust off the filter screen when it is removed. The filling block can seal the wider insertion slot. Attached Figure Description

When the working intensity is not high, the machine can be stopped to drain water.

[0029] Example 2

[0030] The ventilation and dust filtration device for mining operations provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the filter assembly includes a second baffle 10 for blocking water flow. The second baffle 10 is fixedly connected to the bottom wall of the filter box 1 and is located to the right of the curved baffle 9. The second baffle 10 is inclined. A spray plate 11 is fixedly connected to the top wall of the filter box 1. An atomizing nozzle 12 for dust suppression is provided on the lower surface of the spray plate 11. A pump body 13 is fixedly connected to the upper surface of the filter box 1. The output end of the pump body 13 communicates with the interior of the spray plate 11. A water pipe 14 for water flow transmission is fixedly connected to the input end of the pump body 13. The water pipe 14 extends into the interior of the filter box 1. A mounting frame 15 is fixedly connected to the inner wall of the filter box 1. An insertion groove 16 extending into the upper surface of the filter box 1 is provided. A filter screen 17 for triple filtration is provided inside the mounting frame 15. The upper surface of the filter screen 17 is connected to the insertion groove. 16 extends to the outside of the filter box 1. The upper surface of the filter screen 17 is fixedly connected to the mounting plate 18. The mounting plate 18 is provided with fixing bolts 19 for fixing the mounting plate 18. The lower surface of the mounting plate 18 is fixedly connected to the filling block 20 for filling the gap of the insertion groove 16. The filling block 20 is inserted into the inside of the insertion groove 16. The left air box 2 is provided with a dust sensor 21. The dust sensor 21 is electrically connected to the fan 3 and the pump body 13. It can use the spray plate 11 in conjunction with the atomizing nozzle 12 to perform secondary filtration of the air. The presence of the filter screen 17 can further adsorb small dust particles in the air. With the setting that the width of the insertion groove 16 is greater than that of the filter screen 17, the inner wall of the insertion groove 16 will not scrape off the dust on the filter screen 17 when the filter screen 17 is removed. The filling block 20 can close the wider insertion groove 16.

[0031] The first partition 8 is provided in four parts, and the area between the first partition 8 on the right and the anti-curved baffle 9 is set as a water purification zone.

[0032] The usage process of the ventilation and dust filtration device for mining provided by this utility model is as follows:

[0033] When the dust sensor 21 detects a high dust content in the air, the fan 3 on the left side of the air box 2 draws outside air into the air box 2. Then, the air is transmitted to the diverter plate 5 through the transmission pipe 4. The diverter plate 5 divides the air into multiple streams and transmits them to the exhaust plate 6. Finally, the air enters the filter box 1 through the exhaust holes 7 on the multiple exhaust plates 6. The water flow between the first partitions 8 adsorbs the dust in the air. At the same time, the S-shaped arrangement of the first partitions 8 prolongs the time that the air stays in the water, thereby improving the adsorption efficiency of the dust in the water. The adsorbed air rises to the top of the filter box 1 and flows to the right. At this time, the pump body 13 transmits the water inside the clean water area to the spray plate 11. The water is atomized and sprayed out through the atomizing nozzle 12 to adsorb the fine particles in the air for a second time. Then, the air continues to move to the right, passes through the filter screen 17 to complete the third filtration, and is discharged through the right side of the air box 2. During the operation, it is only necessary to periodically drain the sewage inside the filter box 1 and replenish the appropriate water source. The whole process does not require shutdown.
