Description

Technical Field

[0001] The invention belongs to the technical field of dust suppression equipment, in particular to a water sprinkling dust suppression device used in mining areas. Background Art

[0002] The rainwater regulating pool in the mining area is an important facility for collecting, storing and regulating precipitation in the mining area. The water quality of precipitation in some mining areas is relatively good, and the content of pollutants, heavy metals and acidic liquids in the water is low. These water resources can be fully utilized for dust suppression on mining roads, slope replanting and other environmental restoration work. Specifically, the sprinkler truck in the mining area usually extracts water resources from the rainwater regulating pool and sprays the water on the road to achieve the purpose of dust suppression. At present, in the process of dust reduction in mining areas, it is common to transport the water in the rainwater regulating pool to the water tank of the sprinkler truck. When the sprinkler truck drives along the road, it extracts water from the water tank through a high-pressure water pump, and then transports the water to the spray system through the outlet pipe. The spray system atomizes the water into fine droplets through high-pressure water flow and sprays it into the air, thereby effectively suppressing dust and pollutants in the air. In this way, it can not only reduce the dust in the air, but also effectively suppress the spread of pollution, so as to achieve the purpose of dust reduction and environmental protection in mining areas.

[0003] Since rainwater contains certain impurities (such as silt, particles, etc.), these impurities can easily enter the water pump and spray system, thus affecting the normal operation of the water pump and the use of the spray system. Specifically, impurities may clog the spray nozzle, resulting in poor spray effect, and may even damage the water pump, affecting the life and operating efficiency of the equipment. Therefore, in the existing dust suppression system, a filter is usually installed at the water inlet pipe to preliminarily filter the impurities in the water.

[0004] In the prior art, the filter is usually protected by a detachable filter cover, which is fixed at the entrance of the water inlet pipe or directly connected to the water inlet end of the water pump. When cleaning the filter, it is necessary to use tools to remove the screws or buckles on the filter cover for cleaning. This traditional disassembly and assembly method not only consumes a lot of time and energy, but also has low cleaning efficiency.

[0005] To this end, the present invention provides a water sprinkling and dust reduction device for use in mining areas. Summary of the invention

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] Embodiment 1: Figures 1 to 8 As shown, a water sprinkling and dust reduction device applied to a mining area according to an embodiment of the present invention comprises a vehicle body 1, a water tank 2, a water pump 3, a spray system 4 and a filter assembly; The water tank 2, the water pump 3 and the spray system 4 are respectively fixedly mounted on the vehicle body 1, the filter assembly is fixedly mounted on the side of the water tank 2, the filter assembly is connected to the water inlet pipe of the water pump 3, the water sucked into the water pump 3 is filtered by the filter assembly, and the water outlet pipe of the water pump 3 is connected to the spray system 4; The filter assembly includes a housing 5 fixed on the water tank 2, a mounting block 16 is fixed on a sealing plate provided at the bottom of the housing 5, a rotating shaft 10 is rotatably provided above the mounting block 16, a filter screen 9 is fixed to one end of the rotating shaft 10 close to the water tank 2, an impeller 13 is fixed to the middle of the rotating shaft 10, a mounting block 23 is provided on the side of the mounting block 16, the mounting block 16 and the mounting block 23 are respectively provided on both sides of the filter screen 9, and a cleaning brush 12 for cleaning impurities on the surface of the filter screen 9 is fixed in the middle of the mounting block 23; When working, the vehicle body 1, the water tank 2, the water pump 3 and the spray system 4 are all prior arts. When in use, the vehicle body 1 carries the equipment and walks on a road where dust reduction is required. The water in the water tank 2 is pumped out through the water inlet pipe by the water pump 3, and then the water is transported to the spray system 4 through the water outlet pipe. The spray system 4 can atomize the water into fine droplets and spray them into the air to reduce dust and suppress pollution. During the water pumping process of the water pump 3, a continuous water flow is formed in the water inlet pipe. By setting a filter screen 9 in the middle of the outer shell 5, impurities, silt or other solid substances carried in the water can be effectively filtered to avoid Prevent these impurities from entering the water pump 3 and the spray system 4, and prevent the nozzle from being blocked or damaging the water pump 3; in addition, the water flow drives the impeller 13 to rotate, which in turn drives the rotating shaft 10 to rotate, and the rotating shaft 10 also drives the filter 9 to rotate, and the end of the cleaning brush 12 contacts the surface of the filter 9, and the cleaning brush 12 cleans the surface of the filter 9 during its rotation to prevent blockage and keep the surface of the filter 9 clean, so as to maintain the filtering performance of the filter 9; in this way, the filter 9 can be cleaned automatically without the need for manual disassembly of the filter 9 for cleaning, which reduces the workload of personnel and improves the cleaning efficiency.

[0024] The rotating shaft 10 is provided with a rebound assembly 11, and the rebound assembly 11 includes a box body fixed to the top of the mounting block 16, the rotating shaft 10 passes through and is rotatably mounted at the center of the box body, and a coil spring is provided inside the box body, one end of the coil spring is fixedly connected to the rotating shaft 10, and the other end of the coil spring is fixedly connected to the inner wall of the box body; During operation, the water flow pushes the impeller 13 and the rotating shaft 10 to rotate, and synchronously drives the coil spring to move, so that the coil spring is deformed and the coil spring stores energy. When the torsion spring reaches its limit, the rotating shaft 10 stops rotating and the filter screen 9 stops rotating. At this time, the filter screen 9 continues to filter water, and the filter screen 9 and the cleaning brush 12 remain stationary, so as to reduce the friction between the cleaning brush 12 and the filter screen 9, thereby reducing wear and tear, thereby extending the service life of the cleaning brush 12 and the filter screen 9. In addition, the water flow continues to flow and does not affect the normal pumping work of the water pump 3. When the water pump 3 stops working (for example, during the water replenishment process), the water in the pipeline stops flowing, and the water flow no longer pushes the impeller 13. At this time, the coil spring begins to deform and reset, and drives the rotating shaft 10 and the filter screen 9 to rotate in the opposite direction through the coil spring. At this time, the filter screen 9 can move relative to the cleaning brush 12, so that the surface of the filter screen 9 can be cleaned by the cleaning brush 12.

[0025] A bottom box 7 is provided below the housing 5, and the bottom box 7 is fixed below the sealing plate. A piston plate 20 is sealingly and slidably installed inside the bottom box 7, and the inside of the bottom box 7 is separated into a cavity 17 and a cavity 2 19 by the piston plate 20. The middle of the mounting block 23 is hollow, and the side of the mounting block 23 close to the filter screen 9 is open. The cleaning brush 12 is fixed in the middle of the opening, and a drain pipe 22 is fixed at the bottom of the mounting block 23. The bottom end of the drain pipe 22 extends through and extends to the bottom of the cavity 2 19. The sewage pipe 22 is sealed and slidably penetrates the through hole opened on the piston plate 20. A driving assembly for driving the piston plate 20 to move up and down is provided inside the bottom box 7. The driving assembly includes a screw rod 18, which is threadedly connected to the threaded hole opened on the piston plate 20. The top of the screw rod 18 rotates upward and penetrates and extends into the inside of the housing 5. A bevel gear 2 15 is fixed to the top of the screw rod 18. A bevel gear 14 is fixed to the end of the rotating shaft 10 away from the filter screen 9. The bevel gear 14 is meshed with the bevel gear 2 15. During operation, when the water pump 3 stops working, the rotating shaft 10 is driven to rotate in the opposite direction through the coil spring, which can drive the bevel gear 14 to rotate synchronously, and then the bevel gear 14 and the bevel gear 2 15 cooperate to drive the screw rod 18 to rotate. The screw rod 18 is threadedly connected to the piston plate 20, which can push the piston plate 20 to move upward. At this time, the internal volume of the cavity 2 19 below becomes larger, and a negative pressure is generated inside the cavity 2 19, so that water in the inner cavity of the mounting block 2 23 is extracted through the drain pipe 22, and at the same time, impurities scraped off by the cleaning brush 12 are absorbed, so that the impurities near the filter screen 9 can be discharged into the inner cavity 2 in time, so as to avoid impurities from accumulating on the side of the filter screen 9.

[0026] A water suction pipe 21 connected to the cavity 17 is fixed at the bottom of the mounting block 16, a through slot 27 is provided on the side of the mounting block 16 away from the filter screen 9, a flap 28 is rotatably installed on the inner side of the through slot 27 through a torsion spring, and a through slot 26 is provided on the side of the mounting block 16 close to the filter screen 9; when working, the water pump 3 works normally, and the rotating shaft 10 is driven to rotate by the water flow. At this time, the rotating shaft 10, the bevel gear 14, the bevel gear 2 15 and the screw 18 are in forward transmission, and the piston plate 20 is driven downward by the screw 18, and the cavity 17 is in the state of being rotated. The volume becomes larger, and negative pressure is generated inside, and then water is pumped from the inner cavity of the mounting block 16 through the suction pipe 21. During the pumping process, the flap 28 rotates inward to pump water into the mounting block 16 through the through groove 27. When the screw 18 reverses, the piston plate 20 moves upward and discharges the water inside the cavity 17 at the same time. At this time, the flap 28 is closed, and the water flows into the inner cavity of the mounting block 16 and is discharged from the through groove 26, so as to reversely flush the filter 9, further clean the impurities attached to the surface of the filter 9, and improve the cleaning efficiency of the impurities.

[0027] The second through groove 27 is configured to be in a narrow slit shape, so as to enhance the pressure of the water flow ejected from the second through groove 27 during operation, thereby facilitating the flushing of impurities attached to the surface of the filter screen 9 .

[0028] The bottom of the bottom box 7 is provided with a sewage outlet 25, and a flap 1 24 is installed on the outer side of the sewage outlet 25 by rotation through a torsion spring; during operation, when the piston plate 20 moves up, the flap 1 24 blocks the sewage outlet 25, so that a negative pressure is generated inside the cavity 19, so that impurities can be sucked through the sewage pipe 22. When the piston plate 20 moves down again, the sewage in the cavity 19 is squeezed downward to discharge the sewage from the sewage outlet 25, so as to clean the sewage in the cavity 19. At the same time, some sewage will enter the sewage pipe 22. The flap 1 24 can be opened downward manually when the water tank 2 is replenished with water, so that the sewage in the cavity 19 can be completely discharged, so that the internal impurities can be discharged without disassembling the device, thereby improving the sewage discharge efficiency; the flap 1 24 is driven by the torsion spring to cover the outer side of the sewage outlet 25. When the torsion spring reaches the deformation limit, the flap 1 24 blocks the sewage outlet 25, so that water will not leak from the sewage pipe 22 and the sewage hole during the operation of the water pump 3, so as to save water resources.

[0029] Two limit rods 30 are fixed in parallel on the top of the inner cavity of the mounting block 16, and a movable rod 29 is slidably sleeved under the limit rod 30, and a knocking rod 32 is fixed in the middle of the movable rod 29, and the knocking rod 32 is movably inserted in the through groove 27, and a top rod 33 is fixed on the top of the movable rod 29. An impeller 24 is rotatably installed at the bottom of the inner cavity of the mounting block 16 through the mounting shaft, and a disc 35 is fixed on the mounting shaft. A top block 36 that can push the movable rod 29 away from the filter 9 is fixed on the side of the disc 35, and a spring 31 that resets the movable rod 29 is sleeved on the limit rod 30, so that the knocking rod 32 knocks on the side of the filter 9; during operation, when the piston plate 20 moves up, the water inside the cavity 17 is pressed into the mounting block 16 through the suction pipe 21. The impeller 34 is driven by the spring 31 to move toward the filter screen 9, so that the knocking rod 32 can knock on the side of the filter screen 9, and the vibration generated can help the impurities to separate from the surface of the filter screen 9, thereby further improving the cleaning effect of the impurities.

[0030] The shell 5 is configured to be in an arch shape, the outer contour of the filter 9 is matched with the inner wall of the top of the shell 5, and a support seat 37 is fixed in the middle of the top of the sealing plate, and the support seat 37 is matched with the bottom contour of the filter 9; when working, the support seat 37 and the filter 9 cooperate to completely cut off the inside of the shell 5, so that the filter 9 can fully filter the water passing through; the sealing plate is fixed to the bottom of the shell 5 by bolts, so that the sealing plate, the bottom box 7 and the filtering structure above can be disassembled at the same time, which is convenient for overhauling the device; the mounting block 16 and the mounting block 23 are fixed to the sealing plate by bolts, and the filter 9 is fixed to the end of the rotating shaft 10 by bolts. The mounting block 2 23 is disassembled first, and then the filter 9 can be disassembled. The operation is simple, so that the filter 9 can be replaced.

[0031] A joint 6 is installed on the side of the shell 5 away from the water tank 2, and the water inlet pipe of the water pump 3 is fixed on the joint 6; when working, the shell 5 is fixedly connected to the water tank 2 and the joint 6 through flanges, and the joint 6 is connected to the water inlet pipe, so as to facilitate the disassembly and assembly of the device.

[0032] Embodiment 2: Figure 8 As shown, compared with Example 1, another implementation of the present invention is: a mounting groove 8 is provided in the middle of the shell 5, and the outer contour of the filter 9 is slidably inserted into the mounting groove 8; when working, the filter 9 is inserted from the bottom of the mounting groove 8 during installation, which is convenient for quick positioning of the filter 9 and also convenient for quick assembly of the device.

[0033] Working principle: During the water pumping process of the water pump 3, a continuous water flow is formed in the water inlet pipe. By setting a filter screen 9 in the middle of the shell 5, impurities, silt or other solid substances carried in the water can be effectively filtered to prevent these impurities from entering the water pump 3 and the spray system 4, and prevent the nozzle from being blocked or damaging the water pump 3; in addition, the water flow drives the impeller 13 to rotate, thereby driving the rotating shaft 10 to rotate, and the rotating shaft 10 also drives the filter screen 9 to rotate, and the end of the cleaning brush 12 contacts the surface of the filter screen 9. The cleaning brush 12 cleans the surface of the filter screen 9 during its rotation to prevent blockage and keep the surface of the filter screen 9 clean, so as to maintain the filtering performance of the filter screen 9; in this way, the filter screen 9 can be cleaned automatically without the need to manually disassemble the filter screen 9 for cleaning, which reduces the workload of personnel and improves the cleaning efficiency; The water flow drives the impeller 13 and the rotating shaft 10 to rotate, and synchronously drives the coil spring to move, so that the coil spring is deformed and the coil spring stores energy. When the torsion spring reaches its limit, the rotating shaft 10 stops rotating and the filter screen 9 stops rotating. At this time, the filter screen 9 continues to filter water, and the filter screen 9 and the cleaning brush 12 remain stationary, so as to reduce the friction between the cleaning brush 12 and the filter screen 9, thereby reducing wear and tear, thereby extending the service life of the cleaning brush 12 and the filter screen 9. In addition, the water flow continues to flow and does not affect the normal pumping work of the water pump 3. When the water pump 3 stops working (for example, during the water replenishment process), the water in the pipeline stops flowing, and the water flow no longer drives the impeller 13. At this time, the coil spring begins to deform and reset, and drives the rotating shaft 10 and the filter screen 9 to rotate in the opposite direction through the coil spring. At this time, the filter screen 9 can move relative to the cleaning brush 12, so that the surface of the filter screen 9 can be cleaned by the cleaning brush 12. The water pump 3 works normally, and the rotating shaft 10 is driven to rotate by the water flow. At this time, the rotating shaft 10, the bevel gear 14, the bevel gear 2 15 and the screw 18 are in forward transmission, and the piston plate 20 is driven downward by the screw 18. At this time, the volume of the cavity 17 becomes larger, and a negative pressure is generated inside, and then water is pumped from the inner cavity of the mounting block 16 through the suction pipe 21. During the pumping process, the flap 28 rotates inward to pump water into the mounting block 16 through the through groove 27. When the water pump 3 stops working, the rotating shaft 10 is driven to rotate in the opposite direction by the coil spring, which can drive the bevel gear 14, the bevel gear 2 15 and the screw 18 to reverse, and can push the piston plate 20 to move upward to discharge the water inside the cavity 17. At this time, the flap 28 is closed, and the water flows into the inner cavity of the mounting block 16 and is discharged from the through groove 1 26, so as to reversely flush the filter 9. , further cleaning the impurities attached to the surface of the filter 9, and improving the cleaning efficiency of the impurities; in addition, the internal volume of the lower cavity 19 becomes larger, and a negative pressure is generated inside the cavity 19, so that the water in the inner cavity of the mounting block 23 is extracted through the sewage pipe 22, and the impurities scraped off by the cleaning brush 12 are absorbed, so that the impurities near the filter 9 can be discharged into the inner cavity 2 in time, and the impurities are prevented from accumulating on the side of the filter 9; when the piston plate 20 moves down again, the sewage in the cavity 19 is squeezed downward so that the sewage is discharged from the sewage outlet 25, so as to clean the sewage in the cavity 19, and some of the sewage will enter the sewage pipe 22, and the flap 1 24 can be manually opened downward when the water tank 2 is replenished with water, so that the sewage in the cavity 19 can be completely discharged, so that the internal impurities can be discharged without disassembling the device, thereby improving the sewage discharge efficiency.
