Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of dust suppression equipment, specifically relating to a dust suppression device for coal mines. Background Technology
[0002] High dust intensity in fully mechanized coal mining faces pollutes the working environment and can lead to pneumoconiosis, posing a potential threat to workers' lives. Excessive dust concentration can also cause coal mine dust explosions, bringing incalculable disasters and losses to frontline workers, coal mining enterprises, and the nation. Furthermore, coal mining generates significant dust pollution, making dust suppression a critical issue in coal mining operations. Whether the underground working environment meets operational standards directly impacts the health of workers and the overall efficiency of coal mine production; therefore, dust suppression equipment is essential.
[0003] In the underground working environment of coal mines, most existing dust suppression equipment adopts a small trolley design, which moves the nozzles to spray dust suppression in different areas of the mine. However, the internal space of the mine is cave-like, with a complex structure and many obstacles. This structural feature makes it inconvenient to move the equipment during dust suppression spraying operations, and it is also difficult to effectively isolate and treat the dust. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a coal mine dust suppression device that can spray water mist to form a curtain-like covering effect, which can not only effectively reduce dust concentration, but also play a good barrier role.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a coal mine dust suppression device, comprising a water storage tank, a water pump fixedly connected to the outside of the water storage tank, the output end of the water pump being connected to the water storage tank, a connecting pipe being connected to the end of the water storage tank away from the water pump, a first valve being provided between the connecting pipe and the output end of the water storage tank, a water outlet pipe being connected to the end of the connecting pipe away from the water storage tank, a spraying mechanism being provided outside the water outlet pipe, a support plate being welded to the top of the water storage tank, and an adjustable spraying mechanism being provided on the side of the support plate near the water pump.
[0006] Preferably, the spraying mechanism includes multiple connecting sleeves, each of which is connected to the outside of the water outlet pipe, a concave plate is fixedly connected to the outside of each of the multiple connecting sleeves, and a spray head is connected to the outside of each of the multiple connecting sleeves.
[0007] Preferably, each of the concave plates has a rotating rod rotatably connected to its inner cavity, and each of the rotating rods has a fixed plate fixedly connected to its outer surface. Each of the fixed plates has an opening inside its interior.
[0008] Preferably, the adjusting spraying mechanism includes a sleeve rod, which is fixedly connected to the side of the support plate near the water pump. A collecting cylinder is sleeved on the outside of the sleeve rod, and a long tube is wound around the outside of the collecting cylinder.
[0009] Preferably, one end of the long pipe is connected to a water spray head, and the other end of the long pipe is connected to a second valve.
[0010] Preferably, the end of the second valve away from the long pipe is connected to a water inlet pipe, and the water inlet pipe extends to the bottom of the water storage tank.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. When it is necessary to wet the mining area, first pull the long pipe. At this time, the long pipe will detach from the collection cylinder, and the water spray head will move accordingly. When it is pulled to the designated position, close the first valve and open the second valve. Water from the storage tank will flow into the water supply pipe, and after passing through the water supply pipe, it will re-enter the long pipe. Then, the water will pass through the long pipe and be sprayed out through the water spray head. At this time, the mining area can be wetted. Through the above mechanism, the operator can flexibly and accurately locate the area to be mined, and wet the coal seam surface and surrounding environment in these areas. This process can effectively suppress the generation and flying of dust, thereby significantly reducing the dust concentration and providing a cleaner and safer guarantee for the working environment in the mine.
[0012] 2. When it is necessary to block the flow of water, first place the water storage tank on the side of the mine shaft. Then, pull the water outlet pipe, which has a bending effect. At this time, place the fixing plate near the water storage tank on the top of the mine shaft. Then, pass the steel strip through the opening and use a hammer to drive the steel nails into the wall at the top of the mine shaft, thereby achieving the effect of fixing the fixing plate. Because there is a rotating rod between the concave plate and the connecting sleeve, and because the concave plate and the connecting sleeve are fixedly connected, the fixing plate can fit against the top of the mine shaft when fixing it. After installation, multiple connections... The sleeves are all fitted to the top of the mine. After installation, the water pump is started, and water is discharged into the water storage tank through the pump's output end. Then, the water enters the connecting pipe through the water storage tank, and then enters the outlet pipe through the connecting pipe again. At this time, the water is discharged through the cooperation of the connecting sleeve and the nozzle. With the above mechanism, it can be easily installed on the top of the mine. During the dust suppression spraying process, the sprayed water mist can form a curtain-like covering effect, which can not only effectively reduce the dust concentration, but also play a good blocking role to prevent dust from spreading, thereby significantly improving the dust suppression effect and air quality in the mine.

[0015] 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.
[0016] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a coal mine dust suppression device, including a water storage tank 1, a water pump 4 fixedly connected to the outside of the water storage tank 1, the output end of the water pump 4 connected to the water storage tank 1, a connecting pipe 6 connected to the end of the water storage tank 1 away from the water pump 4, a first valve 7 provided between the connecting pipe 6 and the output end of the water storage tank 1, a water outlet pipe 8 connected to the end of the connecting pipe 6 away from the water storage tank 1, a spraying mechanism 2 provided outside the water outlet pipe 8, a support plate 5 welded to the top of the water storage tank 1, and an adjustable spraying mechanism 3 provided on the side of the support plate 5 near the water pump 4.
[0017] In this implementation scheme, water can be stored in the water tank 1, and water can be pumped into the water tank 1 via an external water pipe connected to the water pump 4. The spraying mechanism 3 can be placed on the support plate 5. Due to the unevenness of the mine top, the dust suppression equipment is cleverly designed and can be easily installed on the mine top. During the dust suppression process, the sprayed water mist can form a curtain-like covering effect, which can not only effectively reduce the dust concentration, but also play a good blocking role to prevent the dust from spreading, thereby significantly improving the dust suppression effect and air quality in the mine. By adjusting the spraying mechanism 3, the operator can flexibly and accurately locate the spraying area to be mined, and wet the coal seam surface and surrounding environment in these areas. This process can effectively suppress the generation and flying of dust, thereby significantly reducing the dust concentration and providing a cleaner and safer guarantee for the working environment in the mine.
[0018] Example 2: Please refer to Figure 1-4 Based on Embodiment 1, this utility model provides a technical solution: the spraying mechanism 2 includes multiple connecting sleeves 201, each of which is connected to the outside of the water outlet pipe 8. Each of the multiple connecting sleeves 201 is fixedly connected to a concave plate 202, and each of the multiple connecting sleeves 201 is connected to a spray nozzle 206. Each of the multiple concave plates 202 is rotatably connected to a rotating rod 203, and each of the multiple rotating rods 203 is fixedly connected to a fixing plate 204. Each of the multiple fixing plates 204 has an opening 205 inside.
[0019] In this embodiment, when it is necessary to block the obstruction effect, the water storage tank 1 is first placed on the side ground of the mine, and then the water outlet pipe 8 is pulled. The water outlet pipe 8 has a bending effect. At this time, the fixing plate 204 near the water storage tank 1 is placed on the top of the mine. Then, a steel strip is passed through the opening 205. Then, a hammer is used to hammer the steel nails into the wall of the top of the mine, thereby achieving the effect of fixing the fixing plate 204. Because the concave plate 202 and the connecting sleeve 201 are rotatably connected by a rotating rod 203, and because the concave plate 202 and the connecting sleeve 201 are fixedly connected, the fixing plate 204 can fit against the top of the mine when fixing the top of the mine. After installation, multiple connecting sleeves 201 are attached to the top of the mine. After installation, the water pump 4 is started, and water is discharged into the water storage tank 1 through the output end of the water pump 4. Then the water enters the connecting pipe 6 through the water storage tank 1, and then the water enters the outlet pipe 8 through the connecting pipe 6 again. At this time, the water is discharged through the cooperation of the connecting sleeve 201 and the nozzle 206. With the above mechanism, it can be easily installed on the top of the mine. During the dust suppression spraying process, the sprayed water mist can form a curtain-like covering effect, which can not only effectively reduce the dust concentration, but also play a good blocking role to prevent dust from spreading, thereby significantly improving the dust suppression effect and air quality in the mine.
[0020] Example 3: Please refer to Figure 1-3 Based on Embodiment 1 and Embodiment 2, this utility model provides a technical solution: the spraying mechanism 3 includes a sleeve rod 301, which is fixedly connected to the side of the support plate 5 near the water pump 4. A collection cylinder 302 is sleeved on the outside of the sleeve rod 301, and a long pipe 303 is wound around the outside of the collection cylinder 302. One end of the long pipe 303 is connected to a spray head 304, and the other end of the long pipe 303 is connected to a second valve 305. The end of the second valve 305 away from the long pipe 303 is connected to a water inlet pipe, and the water inlet pipe extends to the bottom of the water storage tank 1.
[0021] In this embodiment, when it is necessary to wet the mining area, the long pipe 303 is first pulled, at which point the long pipe 303 is disengaged from the collection cylinder 302, and the water spray head 304 moves accordingly. When it is pulled to the designated position, the first valve 7 is closed and the second valve 305 is opened. Water from the water storage tank 1 flows into the water supply pipe, and after passing through the water supply pipe, it re-enters the long pipe 303. Subsequently, the water passes through the long pipe 303 and is sprayed out through the water spray head 304, thus wetting the mining area. Through the above mechanism, the operator can flexibly and accurately locate the area to be mined, wetting the coal seam surface and surrounding environment in these areas. This process can effectively suppress the generation and flying of dust, thereby significantly reducing the dust concentration and providing a cleaner and safer guarantee for the working environment in the mine.
[0022] The working principle and usage process of this utility model are as follows: When it is necessary to block the barrier effect, first place the water storage tank 1 on the side ground of the mine, then pull the water outlet pipe 8, which has a bending effect. At this time, place the fixing plate 204 near the water storage tank 1 on the top of the mine, and then pass the steel strip through the opening 205. Then, use a hammer to hammer the steel nails into the wall at the top of the mine, thereby achieving the effect of fixing the fixing plate 204. Because the concave plate 202 and the connecting sleeve 201 are rotatably connected by a rotating rod 20 3. Since the concave plate 202 and the connecting sleeve 201 are fixedly connected, the fixing plate 204 can be attached to the top of the mine when fixing the top of the mine. After installation, multiple connecting sleeves 201 are attached to the top of the mine. After installation, the water pump 4 is started, and water is discharged into the water storage tank 1 through the output end of the water pump 4. Then the water enters the connecting pipe 6 through the water storage tank 1, and then the water passes through the connecting pipe 6 again into the outlet pipe 8. At this time, the water is discharged through the cooperation of the connecting sleeve 201 and the nozzle 206.
[0023] When it is necessary to wet the mining area, first pull the long pipe 303. At this time, the long pipe 303 will detach from the collection cylinder 302, and the water spray head 304 will also move. When it is pulled to the designated position, close the first valve 7 and open the second valve 305. Water from the water storage tank 1 flows into the water supply pipe, and after passing through the water supply pipe, it enters the long pipe 303 again. Then, the water passes through the long pipe 303 and is sprayed out through the water spray head 304. At this time, the mining area can be wetted.
