Description

Technical Field

[0001] This invention relates to intelligent spray dust suppression for mining, and more particularly to an intelligent spray dust suppression device for mining. Background Technology

[0002] Spray dust suppression expands the dust suppression area by atomizing water, saving water resources and avoiding secondary pollution. Mine spray dust suppression is used to reduce the large amounts of dust generated during coal mining, transshipment, and transportation.

[0003] During coal mining, the collected coal is typically placed in a collection box and then transported on a conveyor belt. This transport process generates a large amount of dust, which affects visibility, reduces work efficiency, and poses health risks to workers. Currently, dust is generally reduced by spraying, which significantly decreases dust levels. However, some dust still floats near the spray nozzles. When dust comes into contact with water, it forms clumps. Over time, the amount of clumps increases, greatly limiting the spray nozzles' efficiency and reducing their dust suppression effectiveness. In severe cases, it can even clog the spray nozzles. Summary of the Invention

Several inclined tubes are opened at the top of the inner wall of the nozzle, and the sealing ring two cooperates with the inclined tubes.

[0008] Preferably, it also includes a dust collection mechanism installed inside the housing. The dust collection mechanism includes an air filter and a fluid pipe fixed inside the housing. The fluid pipe is connected to a water pumping mechanism. An impeller is rotatably connected inside the fluid pipe. The rotating shaft of the impeller passes through the fluid pipe and is driven by a transmission belt to two fans. The two fans are rotatably connected above and below the air filter, respectively. A cleaning mechanism is installed inside the housing.

[0009] Preferably, the dust collection mechanism further includes a dust box fixedly installed at the bottom of the housing, and a water filter screen is snapped into the inside of the dust box.

[0010] Preferably, the cleaning mechanism includes a grid plate fixed inside the housing, and the fan above is connected to a rotating roller via a transmission belt. One side of the rotating roller rotates through the air filter and is equipped with a transmission mechanism. One side of the transmission mechanism is equipped with an I-shaped brush plate, which contacts the grid plate.

[0011] Preferably, the cleaning mechanism further includes scrapers, and scrapers are symmetrically fixed to both the front and rear sides of the grid plate.

Detailed Implementation

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] according to Figures 1-9 As shown, the present invention provides a technical solution: a mining intelligent spray dust suppression device, comprising a housing 1 and a frame 2. The housing 1 is bolted to the interior of both sides of the frame 2. A movable component 3 is installed at the bottom of each of the two housings 1. A water pumping mechanism 4 is installed on opposite sides of each of the two housings 1. The water pumping mechanism 4 can be connected to an external water pump. It also includes a flow body 5 symmetrically attached to the frame 2. Several spraying components 6 and 7 are respectively installed at the bottom and top of the flow body 5. The spraying components 6 and 7 are telescopically and sealingly installed with the flow body 5. This telescopic and sealing installation method effectively prevents blockage at the spray outlet. A dust suction mechanism 8 is installed inside each of the two housings 1. A water tank 101 is installed at the top of each of the two housings 1. One of the spraying components 6 is sealed at the bottom of the water tank 101. Both water tanks 101 are symmetrically connected to a telescopic hose 102. One of the water tanks 101 is connected to the flow body 5 through the telescopic hose 102.

[0032] Using the above technical solution, the left and right sides of the frame 2 are installed onto the left and right side frames of the conveyor belt, and the two housings 1 are installed onto the sides of the frame 2 using bolts. After the housings 1 are installed, the moving assembly 3 is snapped into the left and right side frames of the conveyor belt. Then, the two flow bodies 5 are snapped onto the frame 2, and one of the water tanks 101 is connected to the two flow bodies 5 through the telescopic hose 102. At this time, the two housings 1 are located on both sides of the conveyor belt, and the two flow bodies 5 are located above the conveyor belt. The water pumping mechanism 4 is connected to an external water pump, and the water source is drawn by the water pump. The water source flows into the water tank 101 through the dust suction mechanism 8, and then into the two flow bodies 5 through the telescopic hose 102. Subsequently, several spray groups... Component 6 and spraying component 7 spray water to suppress dust generated in the coal mine. Spraying component 6 can suppress dust inside the frame 2, while spraying component 7 can suppress dust above the frame 2. The wide-area spraying of spraying components 6 and 7 can effectively prevent dust from falling onto the spray head. Furthermore, the telescopic and sealed installation of spraying components 6 and 7 can block mud from the outside of the spray head, effectively preventing mud from reducing the dust suppression effect of the spray head and preventing the spray head from clogging. When it is necessary to move, the moving component 3 (which consists of a motor and transmission wheels, and will not be described in detail in the existing technology) can be activated for movement.

[0033] Specifically, the spraying component 6 includes a fixing ring 601. The bottom of the flow body 5 has several through holes corresponding to the spraying component 6, and the fixing ring 601 is fixedly connected inside the through holes. The fixing ring 601 has several triangular flow grooves inside. The top of the fixing ring 601 is rotatably connected to a rotating ring 602. The top of the rotating ring 602 is fixedly connected to a pressing block 603 by a spring. The bottom of the pressing block 603 is rotatably connected through the rotating ring 602 and the fixing ring 601 by an extension shaft, and is fixedly connected to an impeller 604. The bottom of the impeller 604 is fixedly connected to a sealing ring 605, and the sealing ring 605 is movably connected to the through holes of the flow body 5 in a sealed manner.

[0034] Through the above technical solution, when water flows into the flow body 5, the pressure of the water will squeeze the squeezing block 603, causing the squeezing block 603 to drive the impeller 604 and the sealing ring 605 to move downwards. The spring 1 contracts, and the sealing ring 605 moves, no longer blocking the through-hole of the flow body 5. Subsequently, the water flows downwards through several triangular grooves of the fixed ring 601 and contacts the impeller 604, causing the impeller 604 to rotate. The rotating impeller 604 can spray water over a wide area, thereby increasing the dust suppression area and effect. The rotation of the impeller 604 will drive the squeezing block 604 to move downwards. 3. Rotation: The squeezing block 603 drives the rotating ring 602 to rotate synchronously via the spring. Since the rotating ring 602 and the fixed ring 601 are rotatably connected, the rotation of the impeller 604 will not be affected. When the dust suppression work stops, the squeezing block 603 is no longer squeezed by the water source. The spring returns to its original position and drives the impeller 604 and the sealing ring 605 to return to their original positions via the squeezing block 603. The returned impeller 604 will return to the through hole of the flow body 5, and the returned sealing ring 605 will seal the through hole of the flow body 5, effectively preventing the impeller 604 from contacting mud and dust.

[0035] Specifically, the spraying assembly 7 includes a nozzle 701. The top of the flow body 5 has several rotating grooves 501 corresponding to the spraying assembly 7, and the nozzle 701 is rotatably connected within each rotating groove 501. An impeller 702 is fixedly connected to the bottom of the inner wall of the nozzle 701. A sealing ring 703 is movably connected to the top of the inner wall of the nozzle 701 in a sealed manner. A rotating ring 704 is fixedly connected to the bottom of the sealing ring 703 via a spring. A ratchet ring 705 is rotatably connected to the bottom of the rotating ring 704. The ratchet ring 705 is connected to the nozzle 701. 1. Fixed connection: Ratchet ring 1 705 is fitted with ratchet ring 2 706 at the bottom. Impeller 3 707 is fixedly installed at the bottom of ratchet ring 2 706. The bottom of sealing ring 2 703 is rotatably connected to rotating ring 2 704, ratchet ring 1 705 and ratchet ring 2 706 through a through shaft, and is fixedly connected to impeller 3 707. Several inclined tubes 708 are opened at the top of the inner wall of nozzle 701. The inclined tube 708 is inclined at one end at the top of nozzle 701. When sealing ring 2 703 is not moving, it can block the inclined tube 708.

[0036] Through the above technical solution, when water flows into the flow body 5, the water has sufficient pressure to flow into the nozzle 701 and drive the impeller 702 to rotate. The impeller 702 drives the nozzle 701 to rotate within the rotating groove 501. Subsequently, the water continues to flow within the nozzle 701 and drives the impeller 707 to rotate. Figure 6As shown in the diagram, the water source drives impeller 3 707 to rotate clockwise. Impeller 3 707 drives sealing ring 2 703 to rotate synchronously. Sealing ring 2 703 drives rotating ring 2 704 to rotate synchronously via spring 2. Due to the setting of rotating ring 2 704, the rotation of impeller 3 707 is not affected. When impeller 3 707 rotates, it also drives ratchet ring 2 706 to rotate synchronously. The clockwise rotation of ratchet ring 2 706 will cooperate with ratchet ring 1 705, causing ratchet ring 2 706 to drive impeller 3 707 to move away from ratchet ring 1 705. Impeller 3 707 drives sealing ring 2 703 to move synchronously and squeeze spring 2. The movement of sealing ring 2 703 will no longer block the inclined tube 708. At this time, the water source will flow from inside nozzle 701 into inclined tube 708 and spray out from the other end of inclined tube 708. Since the other end of inclined tube 708 is inclined, the water source will be sprayed out in a spiral, which can increase dust suppression. The area and dust reduction effect are further enhanced by the rotating nozzle 701. As the impeller 3 707 rotates, the ratchet ring 2 706 no longer contacts the ratchet ring 1 705. At this time, the spring 2 is released and drives the sealing ring 2 703 to reset. The resetting of the sealing ring 2 703 can seal the inclined pipe 708, effectively preventing mud and dust from contacting the inclined pipe 708. When the sealing ring 2 703 resets, it will drive the impeller 3 707 to reset. The impeller 3 707 drives the ratchet ring 2 706 to re-engage with the ratchet ring 1 705, so that the ratchet ring 2 706 can continue to cooperate with the ratchet ring 1 705. The cooperation between the ratchet ring 1 705 and the ratchet ring 2 706 allows the sealing ring 2 703 to intermittently seal the inclined pipe 708. This method can not only effectively prevent mud and dust from contacting the inclined pipe 708, but also perform dust removal work while avoiding mud and dust.

[0037] Specifically, the vacuuming mechanism 8 includes an air filter 801 and a fluid pipe 802 fixed inside the housing 1. The air filter 801 is made of polytetrafluoroethylene, which has the characteristics of being breathable but not water-filtering. The fluid pipe 802 is connected to the water pumping mechanism 4, and the water tank 101 is connected to the fluid pipe 802. An impeller 803 is rotatably connected inside the fluid pipe 802. The rotating shaft of the impeller 803 passes through the fluid pipe 802 and is connected to two fans 804 via a transmission belt. The two fans 804 are rotatably connected above and below the air filter 801, respectively. A cleaning mechanism 9 is installed inside the housing 1.

[0038] Through the above technical solution, the pumping mechanism 4 is connected to an external water pump, which draws water from the source. The water flows into the fluid pipe 802 through the pumping mechanism 4, and then into the water tank 101. During this process, the water will touch the impeller 803 and drive it to rotate. The impeller 803 drives two fans 804 to rotate via a transmission belt. The two fans 804 will draw dust from between the two housings 1. The drawn dust is filtered by the cleaning mechanism 9 and then comes into contact with the air filter 801. At this time, the dust is completely blocked at the air filter 801. The spraying assembly at the bottom of the water tank 101... When the 6th fan starts working, it sprays dust off the filter screen 801, thus cleaning the filter screen 801 and ensuring its ventilation performance. At this time, the two fans 804 are still working. Since the filter screen 801 is made of polytetrafluoroethylene, which has the characteristics of being breathable but not water-filtering, the two fans 804 will not draw water from the filter screen 801 for cleaning, and water cannot pass through the filter screen 801. Only air can pass through the filter screen 801, thus keeping the inside of the housing 1 under negative pressure, ensuring the dust extraction power of the two fans 804.

[0039] Specifically, the vacuuming mechanism 8 also includes a dust box 805 fixedly installed at the bottom of the housing 1. The bottom of the housing 1 and the top of the dust box 805 are open and connected to each other. A water filter 806 is snapped into the dust box 805. The water filter 806 is made of a high-polymer semi-permeable membrane material, which has the characteristics of filtering water and not being airtight.

[0040] Through the above technical solution, the dust cleaned off the air filter 801 will fall into the dust box 805 along with the water source and be blocked by the water filter 806. Since the water filter 806 is made of a high-polymer semi-permeable membrane material, it has the characteristics of filtering water but not air. Therefore, the water source can be filtered out at the water filter 806, while the outside air will not be drawn out by the two fans 804 from the water filter 806. This keeps the inside of the housing 1 under negative pressure, ensuring the strength of the two fans 804 in drawing out the dust. The spray component 6 at the bottom of the water tank 101 is always in working condition, which can keep the dust at the water filter 806 in a moist state, thereby preventing the dust at this point from being drawn out by the fans 804.

[0041] Specifically, the cleaning mechanism 9 includes a grid plate 902 fixed inside the housing 1. The fan 804 above is connected to a rotating roller 901 via a transmission belt. The rotating roller 901 rotates through the air filter 801 on one side and is equipped with a transmission mechanism 903. The transmission mechanism 903 consists of a cam and a rotating rod that are rotatably connected to each other. The cam is fixedly connected to the rotating roller 901. An I-shaped brush plate 904 is movably connected to one side of the rotating rod. Brushes are provided on the top and bottom long sides of the I-shaped brush plate 904. The brushes of the I-shaped brush plate 904 are in contact with the grid plate 902. There are two I-shaped brush plates 904, which are located on the front and rear sides of the grid plate 902 respectively. The two I-shaped brush plates 904 are fixedly connected by a fixing block. A groove is provided on the right side of the grid plate 902. The fixing block slides in the groove. The transmission mechanism 903 cooperates with the groove to change the rotational motion of the rotating roller 901 into the linear motion of the I-shaped brush plate 904. Scrapers 905 are symmetrically fixed on the front and rear sides of the grid plate 902.

[0042] Through the above technical solution, the dust drawn by the fan 804 first comes into contact with and is filtered by the mesh plate 902. When the fan 804 rotates, it controls the rotation of the rotating roller 901 via a transmission belt. The rotating roller 901 drives the transmission mechanism 903 to move. The transmission mechanism 903, in conjunction with the sliding groove, changes the rotational motion of the rotating roller 901 into the linear motion of the I-shaped brush plate 904. This I-shaped brush plate 904 drives another I-shaped brush plate 904 to move synchronously via a fixed block. The fixed block slides within the sliding groove, thereby causing the I-shaped brush plate 904 to move synchronously. The brushes reciprocate downwards and clean the dust filtered by the mesh plate 902, preventing excessive dust on the mesh plate 902 from affecting the dust extraction power of the fan 804. The cleaned dust falls into the dust box 805 along with the water. When the two I-shaped brush plates 904 move to the top or bottom of the mesh plate 902, the brushes at the top and bottom of the I-shaped brush plates 904 will come into contact with the scraper 905 and cooperate with the scraper 905. The scraper 905 can scrape off the dust on the brushes, thereby ensuring the working performance of the two I-shaped brush plates 904.

[0043] Specifically, the cleaning mechanism 9 also includes a vibrating frame 906 slidably connected to the housing 1. Several springs are provided between the housing 1 and the vibrating frame 906. The vibrating frame 906 is sleeved on the outer wall of the grid plate 902 and slidably connected to it. A vibrating body 907 is fixedly connected to the left side of the vibrating frame 906. Several protrusions are provided on the vibrating body 907. When the I-shaped brush plate 904 moves, it can cooperate with the protrusions of the vibrating body 907.

[0044] With the above technical solution, when the I-shaped brush plate 904 on the front side of the grid plate 902 moves, it will contact and squeeze the protrusion of the vibrator 907. The protrusion drives the vibrating frame 906 to slide through the vibrator 907. The spring is stretched. When the I-shaped brush plate 904 passes the protrusion, the protrusion is no longer squeezed. The spring drives the vibrating frame 906 to reset and collide with the grid plate 902, causing the grid plate 902 to vibrate. This further removes the dust on the grid plate 902. The setting of several protrusions can make the grid plate 902 vibrate multiple times, ensuring the efficiency of dust removal.

[0045] Specifically, the fixed ends of the arched telescopic bodies 201 are fixedly connected to both the front and rear sides of the frame 2. The arched frames 202 are fixedly connected to the opposite sides of the telescopic ends of the two arched telescopic bodies 201. One of the water tanks 101 is connected to the arched frame 202 through the telescopic hose 102. Several spraying components 27 are rotatably and sealed to one side of the arched frame 202.

[0046] With the above technical solution, after the housing 1 is installed, one of the water tanks 101 is connected to the arch frame 202 through the telescopic hose 102. Then, the water in the water tank 101 flows into the arch frame 202 through the telescopic hose 102 and is sprayed out through the spray component 7. The water sprayed out can suppress dust on the front and back sides of the frame 2, thereby increasing the dust suppression area and dust suppression effect. The operator can pull the arch telescopic body 201 to extend it through the handle at the bottom of the arch telescopic body 201. The extension movement of the arch telescopic body 201 will drive the arch frame 202 and the spray component 7 on it to move synchronously. Since the telescopic hose 102 has the property of being telescopic, the extension of the arch telescopic body 201 will not be affected by the telescopic hose 102. After the arch telescopic body 201 is extended, the dust suppression area can be further increased, thereby improving practicality.
