Description

Technical Field

[0001] This invention relates to the field of environmental protection equipment technology for mining, specifically an environmental protection device for phosphorus tailings mines. Background Technology

[0002] Mining environmental protection equipment is mainly used for environmental pollution control and ecological protection during the mining process of various mines such as coal mines and metal mines. It has a wide range of uses and is of great significance. The use of mining environmental protection equipment can effectively reduce pollutant emissions during the mining process, reduce the degree of damage to the ecological environment, protect the surrounding soil, water bodies, atmospheric environment and ecosystem, and promote the sustainable development of the ecological environment.

[0003] When removing dust from mines, baghouse dust collectors are typically used. These collectors use their own air pressure pulses to shake off dust from the outer walls of the bags, which is then temporarily stored inside the ash hopper. This ash is subsequently transferred using specialized transport equipment. A flexible hose is installed at the bottom of the ash hopper, connecting to the inlet of the transport equipment, and is controlled by an ash discharge valve. However, during the dust transfer process, poor sealing at the connection point causes dust to overflow, polluting the surrounding environment. Therefore, an environmental protection device for phosphate tailings mines is proposed to address this problem. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an environmental protection device for phosphorus tailings farms, which has advantages such as improving the sealing of the docking position and reducing dust overflow, thus solving the problem of dust overflow during traditional dust transfer processes.

[0005] To achieve the aforementioned goals of improving the sealing performance of the docking point and reducing dust leakage, the present invention provides the following technical solution: An environmental protection device for phosphorus tailings mining sites is characterized by comprising a support frame, a bag filter dust collector mounted at the top of the support frame, and an ash hopper mounted at the bottom of the support frame. From top to bottom, an ash discharge valve and a telescopic assembly are sequentially mounted on the bottom of the ash hopper, and a telescopic connecting pipe is mounted in the middle of the telescopic assembly. A horizontally placed base plate is mounted on the bottom of the support frame, and a drive vehicle that moves along its length is mounted on its top surface. A docking assembly is mounted on the top surface of the drive vehicle, and a transport platform is docked to the top of the docking assembly. An ash collection box is movably mounted on the top surface of the transport platform, and multiple covers are mounted on the top surface of the ash collection box. Each cover has a first pair of connecting pipes that can dock with the bottom of the telescopic assembly.

[0006] Preferably, a mounting rod is installed on one side of the support frame, and a proximity sensor is installed at its top. Proximity posts are installed at the edges of the top surfaces of the multiple upper covers. The proximity sensors provide signal control for the telescopic assembly and the forward movement of the drive vehicle.

[0007] Preferably, a baffle is rotatably installed on the top surface of each of the inner walls of the multiple upper covers to seal the bottom end of the first connecting pipe, and a reset assembly for pushing the baffle is installed on one side of the top surface of each of the inner walls of the multiple upper covers.

[0008] Preferably, a vertically sliding push rod is installed on one side of the top surface of the upper cover, and an abutment plate is fixedly installed on one side of the baffle, which abuts against the bottom surface of the push rod, and the top end of the push rod is directly opposite the edge of the bottom end of the telescopic assembly.

[0009] Preferably, both sides of the ash collection box are inlaid with multiple transparent plates, which are located below the two ends of multiple top covers.

[0010] Preferably, the multiple top covers are all conical in shape, and a limiting tube is installed in the middle of the top surface of each of the multiple top covers. The multiple push rods are slidably installed inside the limiting tubes.

[0011] Preferably, each of the plurality of reset components includes a fixed plate with bolts threaded to its bottom surface, and springs and sliding blocks slidably mounted on its outer wall. A connecting rod is rotatably mounted on one side of the sliding block, and the other end of the connecting rod is rotatably connected to the bottom surface of the baffle.

[0012] Preferably, the telescopic assembly includes a first pneumatic cylinder and a second pair of connecting pipes, both of which are tapered in shape, with a protrusion at the edge of the second pair of connecting pipes for pushing the push rod.

[0013] Compared with the prior art, the present invention provides an environmental protection device for phosphorus tailings fields, which has the following beneficial effects: 1. This environmental protection device for phosphorus tailings mines, by setting up a telescopic component and multiple first-pair pipes, moves synchronously with the drive vehicle and transport platform, facilitating the movement of multiple proximity columns to below the proximity sensors. Subsequently, the drive vehicle stops, the telescopic component extends and seals with the first-pair pipes, and simultaneously pushes a baffle away from the first-pair pipes through a push rod, opening the first-pair pipes. This allows the ash discharge valve to operate, facilitating the entry of dust from inside the ash hopper into the inner wall of the ash collection box. After ash discharge is completed, the telescopic component is controlled to separate from the first-pair pipes, and the reset component pushes the baffle to re-seal the first-pair pipes, greatly reducing dust overflow during the entire ash discharge process, thereby effectively solving the problems existing in the prior art.

[0014] 2. This environmental protection device for phosphate tailings includes a first pair of connecting pipes and a second pair of connecting pipes, both of which are conical structures. During the docking phase, the device ensures a tight seal between the two pipes. A ash-collecting box is provided, with transparent plates on both sides near the top cover. During the ash-discharging phase, the operator can easily observe the amount of dust inside the ash-collecting box through the transparent plates. This provides a reference for controlling the docking of the telescopic components with the first pair of connecting pipes at different positions, making it easier to fill the ash-collecting box with dust.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-7 An environmental protection device for phosphorus tailings mining includes a support frame 1. A bag filter 2 is installed at the top of the support frame 1, and an ash hopper 3 is installed at the bottom. An ash discharge valve 15 and a telescopic assembly 16 are installed sequentially from top to bottom at the bottom of the ash hopper 3. A telescopic connecting pipe 26 is installed in the middle of the telescopic assembly 16. A horizontally placed base plate 8 is installed at the bottom of the support frame 1. A rack 9 is installed in the middle of the top surface of the base plate 8. First guide rails 7 are installed on both sides of the top surface of the base plate 8 to limit the movement of the drive vehicle 6. An electrical control box is installed at one of the support legs of the support frame 1. The electrical control box contains a PLC controller, various air switches, relays and contactors. Multiple control buttons are installed on the door of the electrical control box, which are electrically connected to the PLC controller.

[0019] A drive vehicle 6 that moves along its length is installed on the top surface of the base plate 8. A motor and gear are installed at the bottom of the drive vehicle 6. The gear is fixedly connected to the output end of the motor. The gear meshes with the rack 9. The motor is powered on and runs, which facilitates the synchronous forward movement of the transport platform 12. A docking assembly 21 is installed on the top surface of the drive vehicle 6. The top of the docking assembly 21 is docked to the transport platform 12. A ash collection box 10 is movably installed on the top surface of the transport platform 12. Multiple covers 11 are installed on the top surface of the ash collection box 10. Each cover 11 has a first connecting pipe 19 that can dock with the bottom end of the telescopic assembly 16. A trailer head is installed at one end of the transport platform 12 to be attached to an external vehicle, which facilitates the subsequent forward movement by external vehicles.

[0020] The docking assembly 21 includes a connector 2101, two second guide rails 2102, and a second pneumatic cylinder 2103. The second pneumatic cylinder 2103 is located between the two second guide rails 2102, and all three are fixedly connected to the top surface of the drive vehicle 6. The output end of the second pneumatic cylinder 2103 is fixedly connected to the connector 2101. Both sides of the bottom end of the connector 2101 protrude outward and are slidably connected to the two second guide rails 2102. A docking head 22 is fixedly installed in the middle of the bottom surface of the transport platform 12, which facilitates slidable connection with the connector 2101. The connector 2101 is tapered and cooperates with the docking head 22, which facilitates the drive vehicle 6 to drive the transport platform 12 to move linearly along the length of the base plate 8, so that the second docking pipe 1603 can dock with the first docking pipe 19 at different positions.

[0021] As an optional technical solution of the present invention: A mounting rod 5 is installed on one side of the support frame 1, and a proximity sensor 20 is installed on its top. Proximity posts 13 are installed at the edges of the top surfaces of multiple covers 11. The proximity sensor 20 controls the forward movement of the telescopic assembly 16 and the drive vehicle 6. The proximity sensor 20 is electrically connected to the PLC controller through wires. When the proximity post 13 approaches the proximity sensor 20, the proximity sensor 20 sends an electrical signal to the PLC controller. The PLC controller controls the motor, the first pneumatic cylinder 1602, and the second pneumatic cylinder 2103 to perform actions.

[0022] As an optional technical solution of the present invention: Each of the inner walls of multiple top covers 11 is rotatably fitted with a baffle 23 that seals the bottom end of the first connecting pipe 19. A reset assembly 24 that pushes the baffle 23 is installed on one side of the inner wall of multiple top covers 11. The four sides of multiple top covers 11 are fixedly connected to the top of the ash collection box 10 by bolts, which facilitates the separate processing and manufacturing of the top covers 11 and the ash collection box 10 and makes assembly easier. One side of the baffle 23 is rotated with the top cover 11 by a pin, which is controlled by the reset assembly 24 and the push rod 17 respectively. Under the pushing action of the push rod 17, it pushes the reset assembly 24 to move and compresses the spring 2402, so that the first connecting pipe 19 is opened. When the pressure of the push rod 17 is removed, the spring 2402 in the reset assembly 24 pushes the sliding block 2404 and the connecting rod 2403, so that the baffle 23 is reset to prevent dust from overflowing.

[0023] As an optional technical solution of the present invention: A vertically sliding push rod 17 is installed on one side of the top surface of the top cover 11. An abutment plate 27 is fixedly installed on one side of the baffle 23, which abuts against the bottom surface of the push rod 17. The top of the push rod 17 is directly opposite the edge of the bottom of the telescopic assembly 16. The abutment plate 27 facilitates cooperation with the push rod 17. When the first pneumatic cylinder 1602 in the telescopic assembly 16 extends, it facilitates the lowering of the second pair of connecting pipes 1603 and their docking with the first pair of connecting pipes 19. The second pair of connecting pipes 1603 drives the push rod 17 to lower, which facilitates the pushing and rotating of the baffle 23 through the abutment plate 27, opening the first pair of connecting pipes 19 and allowing dust to enter the interior of the dust collection box 10.

[0024] As an optional technical solution of the present invention: Multiple transparent plates 4 are embedded on both sides of the ash collection box 10. The multiple transparent plates 4 are located below the two ends of multiple top covers 11. The multiple transparent plates 4 make it convenient for operators to visually observe the position and height of the dust inside the ash collection box 10. The multiple top covers 11 facilitate the installation of multiple first pair pipes 19 and provide docking positions for multiple second pair pipes 1603, so that the dust can fill the interior of the ash collection box 10 as much as possible.

[0025] As an optional technical solution of the present invention: Multiple top covers 11 are conical in shape, and a limiting tube 18 is installed in the middle of the top surface of each top cover 11. Multiple push rods 17 are slidably installed inside the limiting tube 18. The limiting tube 18 provides an installation position for the push rods 17. At the same time, during the pushing stage of the push rods 17 by the protrusion 25, it is ensured that the push rods 17 can slide vertically and push the abutment plate 27 to facilitate the rotation of the baffle 23 and open the first pair of connecting pipes 19. The conical structure of the multiple top covers 11 provides an installation position for the reset assembly 24. At the same time, after the dust completely covers the transparent plate 4, the dust discharge process must be stopped to avoid the dust position being too high and affecting the rotation of the baffle 23.

[0026] As an optional technical solution of the present invention: Each of the multiple reset components 24 includes a fixed plate 2401 with bolts 2405 threaded to its bottom surface. Springs 2402 and sliding blocks 2404 are slidably mounted on its outer wall. A connecting rod 2403 is rotatably mounted on one side of the sliding block 2404, and the other end of the connecting rod 2403 is rotatably connected to the bottom surface of the baffle 23. The bolts 2405 have threads at their ends and a smooth structure in the middle to avoid interfering with the sliding of the sliding block 2404. Springs 2402 are respectively mounted on the outer wall of the two bolts 2405. When the sliding block 2404 compresses the spring 2402, the spring 2402 accumulates elastic potential energy. When the push rod 17 removes the pressure, the spring 2402 can push the sliding block 2404. The sliding block 2404 pushes the baffle 23 to rotate through the connecting rod 2403, which facilitates the sealing of the first connecting pipe 19 and prevents dust from overflowing.

[0027] As an optional technical solution of the present invention: The telescopic assembly 16 includes a first pneumatic cylinder 1602 and a second pair of connecting pipes 1603. Both the second pair of connecting pipes 1603 and the first pair of connecting pipes 19 are conical in shape. The edge of the second pair of connecting pipes 1603 has a protrusion 25 that pushes the push rod 17. The telescopic assembly 16 also includes a connecting ring frame 1601, the top of which is fixedly connected to the bottom of the ash discharge valve 15 by flange bolts. The two sides of the connecting ring frame 1601 are pushed outward to provide an installation position for the first pneumatic cylinder 1602. With this as support, the extension or retraction of the first pneumatic cylinder 1602 can push the second pair of connecting pipes 1603 to move vertically, thereby controlling the docking and separation of the second docking mechanism 1606 and the first pair of connecting pipes 19.

[0028] The environmental protection equipment used in this phosphorus tailings farm includes the following steps: 1) The transport platform 12 moves to the top position of the drive vehicle 6, and at the same time the docking component 21 is activated, so that the connector 2101 docks with the docking head 22; 2) The drive vehicle 6 drives the transport platform 12 and the ash box 10 to move together. When the approach column 13 moves to the bottom of the proximity sensor 20, the proximity sensor 20 sends a control signal to make the drive vehicle 6 and the telescopic assembly 16 extend respectively. 3) The two first pneumatic cylinders 1602 in the telescopic assembly 16 extend synchronously, so that the second connecting pipe 1603 and the first connecting pipe 19 are docked and connected. 4) The protrusion 25 presses down on the push rod 17, and at the same time drives the baffle 23 to rotate at a certain angle, so that the first pair of pipes 19 is opened; 5) The ash discharge valve 15 is activated, allowing the dust inside the ash hopper 3 to enter the ash collection box 10 through the connecting pipe 26.

[0029] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0030] In operation, the transport platform 12 moves to the top position of the drive vehicle 6, while its forward direction remains parallel to the length direction of the first guide rail 7. Then, the operator controls the docking assembly 21 to actuate. The second pneumatic cylinder 2103 pushes the connector 2101 to rise and dock with the coupling 22. The motor at the bottom of the drive vehicle 6 operates, and the gear meshes with the rack 9, causing the transport platform 12 and the ash collection box 10 to move together. When the proximity column 13 moves below the proximity sensor 20, the proximity sensor 20 sends a signal to the P inside the electrical control box. The LC controller sends a control signal, and the PLC controller controls the drive vehicle 6 to extend the telescopic assembly 16. The two first pneumatic cylinders 1602 in the telescopic assembly 16 extend synchronously, so that the second pair of connecting pipes 1603 and the first pair of connecting pipes 19 are connected. At the same time, the connecting pipe 26 is stretched. Then the protrusion 25 presses down the push rod 17, which drives the baffle 23 to rotate at a certain angle, so that the first pair of connecting pipes 19 is opened and the ash discharge valve 15 is activated, so that the dust inside the ash hopper 3 enters the ash collection box 10 along the connecting pipe 26.

[0031] In summary, this environmental protection device for phosphate tailings, by setting up a telescopic component 16 and multiple first-connection pipes 19, allows multiple proximity posts 13 to move to below the proximity sensor 20 as the drive vehicle 6 and transport platform 12 move forward synchronously. Subsequently, the drive vehicle 6 stops, the telescopic component 16 extends and seals with the first-connection pipes 19, and simultaneously, the push rod 17 pushes the baffle 23 away from the first-connection pipes 19, opening them. This allows the ash discharge valve 15 to operate, facilitating the entry of dust from the ash hopper 3 into the inner wall of the ash collection box 10. After ash discharge is complete, the telescopic component 16 separates from the first-connection pipes 19, and the reset component 2... The top push plate 23 re-seals the first pair of pipes 19, greatly reducing dust overflow during the entire ash unloading process, thus effectively solving the problems existing in the prior art. By setting the first pair of pipes 19 and the second pair of pipes 1603, both of which are conical structures, the sealing between them is ensured during the docking stage. By setting the ash collection box 10, and opening transparent plates 4 on both sides of the ash collection box 10 near the top cover 11, the operator can easily observe the amount of dust inside the ash collection box 10 through the transparent plates 4 during the ash unloading stage. This provides a reference for controlling the docking of the telescopic component 16 with the first pair of pipes 19 at different positions, making it easier to fill the ash collection box 10 with dust.
