Description

Technical Field

[0001] The invention relates to intelligent spray dust suppression for mining, and in particular to an intelligent spray dust suppression device for mining. Background Art

[0002] Spray dust suppression is to expand the dust reduction area by atomizing water, which saves water resources and does not cause secondary pollution. Mine spray dust suppression is used to reduce the large amount of dust generated during coal collection, transfer and transportation. When collecting coal in a mine, the collected coal is usually placed in a collection box for collection, and the collection box is placed on a conveyor belt for transportation. During the transportation of the coal in the mine, a large amount of dust will be generated. The dust will affect the visibility of the workers, reduce the work efficiency of the workers, and endanger the health of the workers. The existing method is generally to reduce the dust by spraying. This method can greatly reduce the amount of dust, but some dust will still float near the spray head. Dust will form mud when it comes into contact with water. As time goes by, the number of mud blocks will increase, which will greatly limit the working efficiency of the spray head, thereby causing the dust reduction effect of the spray head to deteriorate, and in severe cases, the spray head will be blocked.

DETAILED DESCRIPTION

[0020] 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.

[0021] according to Figure 1-Figure 9 As shown, the present invention provides a technical solution, a kind of intelligent spray dust suppression device for mining, including a shell 1 and a frame 2, the shells 1 are installed inside the left and right sides of the frame 2 by bolts, the moving components 3 are installed at the bottom of the two shells 1, and the opposite sides of the two shells 1 are installed with pumping mechanisms 4, the pumping mechanisms 4 can be externally connected to a water pump, and also include a flow body 5 symmetrically connected to the frame 2, and a plurality of spraying components 1 6 and spraying components 2 7 are installed at the bottom and top of the flow body 5 respectively, and the spraying components 1 6 and the spraying components 2 7 are telescopically and sealedly installed with the flow body 5, and the telescopic and sealed installation method can effectively avoid blockage at the spray outlet, and dust suction mechanisms 8 are installed inside the two shells 1, and water tanks 101 are installed on the tops of the two shells 1, one of which is sealedly installed at the bottom of the water tank 101, and the two water tanks 101 are symmetrically connected with telescopic hoses 102, and one of the water tanks 101 is connected with the flow body 5 through the telescopic hose 102.

[0022] Through the above technical solution, the left and right sides of the frame 2 are installed on the left and right side frames of the conveyor belt, and the two shells 1 are installed on the two side positions of the frame 2 by bolts. After the shell 1 is installed, the moving component 3 will be clamped in the left and right side frames of the conveyor belt, and then the two flow bodies 5 will be clamped on the frame 2, and one of the water tanks 101 will be connected to the two flow bodies 5 through the telescopic hose 102. At this time, the two shells 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 water is extracted through the water pump. The water source flows into the water tank 101 through the dust suction mechanism 8, and flows into the two flow bodies 5 through the telescopic hose 102, and then several spraying groups are sprayed. Component 1 6 and spray component 2 7 spray water to suppress the dust generated by the coal mine. Spray component 1 6 can suppress the dust inside the frame 2, and spray component 2 7 can suppress the dust above the frame 2. The large-scale spraying of spray component 1 6 and spray component 2 7 can effectively prevent the dust from falling on the spray head, and the telescopic and sealed installation method of spray component 1 6 and spray component 2 7 can block the mud blocks outside the spray head, effectively avoiding the situation where the mud blocks reduce the dust suppression effect of the spray head, and prevent the spray head from being blocked. When it is necessary to move, start the moving component 3 (the moving component 3 is composed of a motor and a transmission wheel, and the prior art is not repeated) to move.

[0023] Specifically, the spray assembly 6 includes a fixed ring 601, a plurality of through holes corresponding to the spray assembly 6 are opened at the bottom of the flow body 5, and the fixed ring 601 is fixedly connected in the through hole, a plurality of triangular flow grooves are opened inside the fixed ring 601, the top of the fixed ring 601 is rotatably connected to a rotating ring 602, the top of the rotating ring 602 is fixedly connected to an extrusion block 603 through a spring, the bottom of the extrusion block 603 is rotatably penetrated by the rotating ring 602 and the fixed ring 601 through 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 hole of the flow body 5 in a sealed manner.

[0024] Through the above technical solution, when the water source flows into the flow body 5, the pressure of the water source will squeeze the squeezing block 603, so that the squeezing block 603 drives the impeller 1 604 and the blocking ring 1 605 to move downward, the spring contracts, and the blocking ring 1 605 moves and no longer blocks the through hole of the flow body 5. Then the water source flows downward through the several triangular flow grooves of the fixed ring 601 and contacts the impeller 1 604, so that the impeller 1 604 rotates. The rotating impeller 1 604 can spray the water source over a large range, thereby increasing the dust reduction area and the dust reduction effect. The rotation of the impeller 1 604 will drive the squeezing block 60 3 rotates, the squeezing block 603 drives the rotating ring 1 602 to rotate synchronously through the spring 1, and since the rotating ring 1 602 is rotatably connected with the fixed ring 601, the rotation of the impeller 1 604 will not be affected in any way. When the dust suppression work is stopped, the squeezing block 603 is no longer squeezed by the pressure of the water source, and the spring 1 is reset and drives the impeller 1 604 and the blocking ring 1 605 to reset through the squeezing block 603. The impeller 1 604 resets to return to the through hole of the flow body 5, and the blocking ring 1 605 resets to block the through hole of the flow body 5, thereby effectively preventing the impeller 1 604 from contacting with mud and dust.

[0025] Specifically, the spray assembly 27 includes a spray head 701, a plurality of rotating grooves 501 corresponding to the spray assembly 27 are opened on the top of the flow body 5, and the spray head 701 is rotatably connected in the rotating groove 501, the bottom of the inner wall of the spray head 701 is fixedly connected to the impeller 2 702, the top of the inner wall of the spray head 701 is sealed and movably connected to the blocking ring 2 703, the bottom of the blocking ring 2 703 is fixedly connected to the rotating ring 2 704 through the spring 2, the bottom of the rotating ring 2 704 is rotatably connected to the ratchet ring 1 705, and the ratchet ring 1 705 is connected to the spray head 70 1 is fixedly connected, the bottom of the ratchet ring 1 705 is matched with the ratchet ring 2 706, the bottom of the ratchet ring 2 706 is fixedly installed with the impeller 3 707, the bottom of the blocking ring 2 703 rotatably penetrates the rotating ring 2 704, the ratchet ring 1 705 and the ratchet ring 2 706 through the through shaft, and is fixedly connected with the impeller 3 707, a plurality of inclined tubes 708 are opened on the top of the inner wall of the nozzle 701, and one end of the inclined tube 708 located at the top of the nozzle 701 is inclined, and the inclined tube 708 can be blocked when the blocking ring 2 703 does not move.

[0026] Through the above technical solution, when the water source flows into the flow body 5, the water source has sufficient pressure to flow into the nozzle 701 and drive the second impeller 702 to rotate. The second impeller 702 drives the nozzle 701 to rotate in the rotating groove 501. Then the water source continues to flow in the nozzle 701 and drives the third impeller 707 to rotate. Figure 6As shown in the direction, the water source will drive impeller three 707 to rotate clockwise, and impeller three 707 drives blocking ring two 703 to rotate synchronously. Blocking ring two 703 drives rotating ring two 704 to rotate synchronously through spring two. Through the setting of rotating ring two 704, the rotation of impeller three 707 will not be affected in any way. When impeller three 707 rotates, it will also drive ratchet ring two 706 to rotate synchronously. The clockwise rotation of ratchet ring two 706 will cooperate with ratchet ring one 705, so that ratchet ring two 706 drives impeller three 707 to move in the direction away from ratchet ring one 705. Impeller three 707 drives blocking ring two 703 to move synchronously and squeeze spring two. The movement of blocking ring two 703 will no longer block the inclined pipe 708. At this time, the water source will flow into the inclined pipe 708 from the inside of the nozzle 701 and be sprayed out from the other end of the inclined pipe 708. Since the other end of the inclined pipe 708 is inclined, the water source will be sprayed out in a spiral, which can increase dust reduction. The area and dust reduction effect, combined with the rotating nozzle 701, can further reduce the dust area and dust reduction effect, with the rotation of the impeller three 707, the ratchet ring two 706 no longer contacts and cooperates with the ratchet ring one 705, at this time the spring two is released and drives the sealing ring two 703 to reset, the sealing ring two 703 reset can block the inclined tube 708, can effectively prevent mud and dust from contacting the inclined tube 708, when the sealing ring two 703 is reset, it will drive the impeller three 707 to reset, the impeller three 707 drives the ratchet ring two 706 to be re-stuck in the ratchet ring one 705, so that the ratchet ring two 706 can continue to cooperate with the ratchet ring one 705, the cooperation of the ratchet ring one 705 and the ratchet ring two 706 can make the sealing ring two 703 intermittently block the inclined tube 708, this method can not only effectively prevent mud and dust from contacting the inclined tube 708, but also can perform dust removal work while avoiding mud and dust.

[0027] Specifically, the dust collection mechanism 8 includes an air filter net 801 and a fluid pipeline 802 fixed to the inside of the shell 1. The air filter net 801 is made of polytetrafluoroethylene, which is breathable but not water-filtering. The fluid pipeline 802 is connected to the pumping mechanism 4, and the water tank 101 is connected to the fluid pipeline 802. The fluid pipeline 802 is rotatably connected to an impeller four 803. The rotating shaft of the impeller four 803 passes through the fluid pipeline 802 and is connected to two fans 804 through a transmission belt. The two fans 804 are rotatably connected to the top and bottom of the air filter net 801 respectively. A cleaning mechanism 9 is installed inside the shell 1.

[0028] Through the above technical solution, the pumping mechanism 4 is connected to an external water pump, and water is drawn through the water pump. The water flows into the fluid pipe 802 through the pumping mechanism 4, and then flows into the water tank 101. During this process, the water will touch the impeller 4 803 and drive it to rotate. The impeller 4 803 drives the two fans 804 to rotate through the transmission belt. The two fans 804 will extract the dust between the two shells 1. The extracted dust is filtered by the cleaning mechanism 9 and then contacts the air filter 801. At this time, the dust is completely blocked at the air filter 801, and the spray component at the bottom of the water tank 101 1-6 starts to work, sprays the dust on the air filter net 801 to make the dust fall off, thereby cleaning the air filter net 801 and ensuring the ventilation performance of the air filter net 801. At this time, the two fans 804 are still working. Since the air filter net 801 is made of polytetrafluoroethylene, it is breathable but not water-filtering. Therefore, the two fans 804 will not draw water for cleaning the air filter net 801, and the water source cannot pass through the air filter net 801. Only gas can pass through the air filter net 801, so that the interior of the shell 1 is always in a negative pressure state, ensuring the strength of the two fans 804 in extracting dust.

[0029] Specifically, the dust suction mechanism 8 also includes a dust box 805 fixedly installed at the bottom of the shell 1, the bottom of the shell 1 and the top of the dust box 805 are in an open state and are connected to each other, and a water filter net 806 is clamped inside the dust box 805. The water filter net 806 is made of a polymer semi-permeable membrane material, which has the characteristics of filtering water but not being airtight.

[0030] Through the above technical solution, the dust cleaned from the air filter net 801 will fall into the dust box 805 along with the water source and be blocked by the water filter net 806. Since the water filter net 806 is made of a polymer semi-permeable membrane material and has the characteristics of filtering water but not being airtight, the water source can be filtered out at the water filter net 806, and the external gas will not be extracted from the water filter net 806 by the two fans 804. In this way, the interior of the shell 1 is always in a negative pressure state, ensuring the strength of the two fans 804 in extracting dust. The spraying component 6 at the bottom of the water tank 101 is always in working condition, which can ensure that the dust at the water filter net 806 is always in a moist state, thereby preventing the dust there from being extracted by the fan 804.

[0031] Specifically, the cleaning mechanism 9 includes a grid plate 902 fixedly connected to the inside of the shell 1, and the fan 804 above is connected to a rotating roller 901 through a transmission belt. One side of the rotating roller 901 rotates through the air filter 801 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, and one side of the rotating rod is movably connected to an I-shaped brush plate 904. Brushes are provided on one side of 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. Two I-shaped brush plates 904 are provided, and are respectively located on the front and rear sides of the grid plate 902. The two I-shaped brush plates 904 are fixedly connected by a fixed block. A slide groove is opened on the right side of the grid plate 902. The fixed block slides in the slide groove. The transmission mechanism 903 cooperates with the slide groove to change the rotational motion of the rotating roller 901 into a 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.

[0032] Through the above technical solution, the dust extracted by the fan 804 will first contact with the grid plate 902 and be filtered. When the upper fan 804 rotates, the rotating roller 901 is controlled to rotate through the transmission belt, and the rotating roller 901 drives the transmission mechanism 903 to move. The transmission mechanism 903 cooperates with the slide groove to change the rotational motion of the rotating roller 901 into the linear motion of the I-shaped brush plate 904. The I-shaped brush plate 904 drives another I-shaped brush plate 904 to move synchronously through the fixed block. The fixed block is located in the slide groove and slides, so that the I-shaped brush plate 904 The two I-shaped brush plates 904 reciprocate upward and downward and clean the dust filtered by the mesh plate 902 to prevent excessive dust on the mesh plate 902 from affecting the dust extraction force of the fan 804. The cleaned dust will fall into the dust box 805 along with the water source. When the two I-shaped brush plates 904 move to the top or bottom of the mesh plate 902, the brushes on the top and bottom of the I-shaped brush plates 904 will contact 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.

[0033] Specifically, the cleaning mechanism 9 also includes a vibration frame 906 that is slidably connected to the shell 1. A number of springs are provided between the shell 1 and the vibration frame 906. The vibration frame 906 is sleeved on the outer wall of the grid plate 902 and is slidably connected thereto. A vibration body 907 is fixedly connected to the left side of the vibration frame 906. The vibration body 907 is provided with a number of protrusions. The I-shaped brush plate 904 can cooperate with the protrusions of the vibration body 907 when it moves.

[0034] Through the above technical solution, when the I-shaped brush plate 904 on the front side of the grid plate 902 moves, it will touch and squeeze the protrusion of the vibrating body 907, and the protrusion drives the vibration frame 906 to slide through the vibrating body 907, and the spring three is stretched. When the I-shaped brush plate 904 passes over the protrusion, the protrusion is no longer squeezed, and the spring three drives the vibration frame 906 to reset and collide with the grid plate 902, causing the grid plate 902 to vibrate, thereby further removing the dust on the grid plate 902. The setting of several protrusions can make the grid plate 902 vibrate multiple times, thereby ensuring the efficiency of dust removal.

[0035] Specifically, the fixed ends of the arched telescopic bodies 201 are fixedly connected on both the front and rear sides of the frame 2, and the opposite sides of the telescopic ends of the two arched telescopic bodies 201 are fixedly connected to the arched frames 202, one of the water tanks 101 is connected to the arched frame 202 through a telescopic hose 102, and a plurality of spraying components 27 are sealed and rotatably connected to one side of the arched frame 202.

[0036] Through the above technical solution, after the shell 1 is installed, one of the water tanks 101 is connected to the arch frame 202 through the telescopic hose 102, and then the water source in the water tank 101 will flow into the arch frame 202 through the telescopic hose 102 and be sprayed out through the spray assembly 27. The water source sprayed therefrom can reduce the dust on the front and rear sides of the frame 2, thereby increasing the dust reduction area and the dust reduction effect. The staff can pull the arch telescopic body 201 to extend 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 assembly 27 thereon to move synchronously. Since the telescopic hose 102 has a telescopic performance, 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 reduction area can be further increased, thereby improving practicality.
