Description

Technical Field

[0001] This invention relates to the field of mine wastewater treatment, specifically to a wastewater treatment device for mine development. Background Technology

[0002] Wastewater treatment facilities in mines are a series of specialized equipment and technical systems designed to address the large amounts of wastewater generated during mining activities. The composition of this type of wastewater varies significantly depending on the type of mineral, but it generally has the characteristics of high suspended solids concentration and complex composition.

[0003] Patent CN120607307A discloses a wastewater treatment device based on high-efficiency activated carbon, including a treatment tower. A flow guide hood is connected to the upper middle part of the inner wall of the treatment tower, and an inlet pipe is connected to the upper part of one side of the flow guide hood. The upper end of the inlet pipe extends through to the upper end of the treatment tower. A dirt removal mechanism is connected to the upper middle part of the treatment tower. The dirt removal mechanism includes a drive motor and a gear ring. The output end of the drive motor extends through to the interior of the treatment tower, and a centrifugal disc is connected to the output end of the drive motor. This invention achieves efficient pretreatment of wastewater and stable adsorption of activated carbon through the settings of high-efficiency dirt removal, dynamic leveling, and automatic flushing, effectively improving the wastewater treatment effect, reducing operating costs, and extending the service life of equipment. However, the above-mentioned device is difficult to fully utilize activated carbon, resulting in excessively high subsequent production costs. Therefore, a wastewater treatment device for mining operations is proposed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a wastewater treatment device for mining operations, addressing the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a sewage treatment device for mining operations, comprising a box body, a drain faucet fixedly connected to the inner wall of the box body, a main shaft provided on the inner wall of the box body, a filtration mechanism provided on the inner wall of the box body, a top cover installed on the top of the box body, a medicine box provided on the surface of the box body, a cleaning mechanism provided on the inner wall of the box body, the filtration mechanism comprising a cylindrical plate, a screen cylinder fixedly connected to the bottom surface of the cylindrical plate, a sleeve rotatably connected to the inner wall of the screen cylinder, a movable cylinder rotatably connected to the bottom end of the sleeve, and an elastic telescopic rod fixedly connected to the circumference of the movable cylinder, the end of the elastic telescopic rod away from the main shaft being fixedly connected to the main shaft. A wedge is fixedly connected to the inner wall of the sleeve. A reciprocating screw is rotatably connected to the inner wall of the sleeve. A brush is movably connected to the circumferential surface of the reciprocating screw. A limit plate is fixedly connected to the circumferential surface of the sleeve, and a handle is fixedly connected to the top of the limit plate. A stirring rod is fixedly connected to the circumferential surface of the sleeve. A cylinder wall is fixedly connected to the inner wall of the housing. A cylinder plate is rotatably connected to the circumferential surface of the sleeve. The bottom end of the sleeve contacts the inner wall of the movable cylinder. A roller is fixedly connected to the end of the reciprocating screw away from the main shaft, and the circumferential surface of the roller contacts the top surface of the cylinder plate. The brush contacts the surface of the limit plate. A one-way spiral groove is formed on the inner wall of the cylinder wall. The reciprocating screw is located away from the main shaft. A protrusion is provided on one end of the shaft, and the protrusion is slidably connected to a one-way spiral groove opened in the inner wall of the cylinder. The inner wall of the cylinder has a sliding groove, the depth of which is less than the one-way spiral groove. The wedge contacts the inner wall of the cylinder. When the equipment starts, the main shaft rotates, driving the movable cylinder upwards. The movable cylinder drives the screen cylinder upwards, and the screen cylinder drives the cylinder plate upwards. Simultaneously, the reciprocating screw drives the sleeve to rotate along the circumference of the main shaft. The rotation of the reciprocating screw causes the rollers on it to contact and rotate at the top of the movable cylinder. The rotation of the rollers causes the reciprocating screw to rotate on the inner wall of the sleeve, and also drives the brush along the limiting plate. The side moves on the top surface of the cylinder plate, and the rotation of the cylinder sleeve drives the stirring rod to rotate along the circumference of the main shaft. When the equipment starts, the activated carbon placed in the screen cylinder is continuously turned over and stirred, ensuring that the activated carbon can be fully utilized in the device, reducing the subsequent production cost of the device. When the device needs to replace the activated carbon, the top cover is opened and the worker pulls the handle. The handle drives the limit plate to move upward, the limit plate drives the cylinder sleeve to move upward, and the cylinder sleeve drives the screen cylinder to move upward until the screen cylinder is completely pulled out. Then, the newly prepared activated carbon is put into the screen cylinder. The wedges that slide on the inner wall of the cylinder can pull out the entire screen cylinder after the device finishes production, which is convenient for subsequent replacement of activated carbon and improves the working efficiency of the device.

[0006] Preferably, the medicine box includes a top plate, a water discharge plate, a grooved wheel, a limiting cover, a medicine box, a delivery tube, and a pull rod. The top plate is fixedly connected to the inner wall of the box body. The water discharge plate is slidably connected to the inner wall of the top plate via a spring. The medicine box is fixedly connected to the outer side of the box body. The delivery tube is fixedly connected to the inner wall of the medicine box. The grooved wheel is rotatably connected to the inner wall of the medicine box. The limiting cover is fixedly connected to the inner wall of the box body. The pull rod is fixedly connected to the surface of the water discharge plate. The bottom surface of the water discharge plate is in contact with the top surface of the limiting cover. The circumferential surface of the pull rod is in contact with the inner wall of the grooved wheel. The water discharge plate is positioned on the movement trajectory of the wedge. The water discharge plate is rotatably connected to the circumferential surface of the main shaft. When the main shaft rotates and drives the movable cylinder to move downwards, the movable cylinder drives the spring... When the elastic telescopic rod moves downward, it drives the wedge to move downward. When the wedge moves downward to the working range of the discharge plate, the wedge drives the discharge plate to move outward along the inclined surface set on the discharge plate. This realizes intermittent water discharge after the activated carbon filtration is completed, ensuring that the activated carbon completely treats the sewage. At the same time as the discharge plate moves outward, the discharge plate drives the pull rod to move outward. The pull rod drives the grooved wheel to rotate inward on the inner wall of the delivery pipe, and the notch on the grooved wheel pushes out a portion of the medicine in the delivery pipe into the device. When the discharge plate is pulled open, the pull rod fixed to the side of the discharge plate drives the grooved wheel to rotate, adding the chemical treatment agent in the delivery pipe into the device. This realizes intermittent dosing of the device and reduces secondary pollution of sewage caused by the addition of chemicals.

[0007] Preferably, the cleaning mechanism includes a mixing drum, a stirring plate, a waste bin, a rocker arm, a scraper, and a discharge plate. The waste bin is fixedly connected to the bottom of the housing, the mixing drum is fixedly connected to the top of the waste bin, the stirring plate is fixedly connected to the circumferential surface of the main shaft, the rocker arm is hinged to the surface of the stirring plate by a torsion spring, the scraper is hinged to the surface of the rocker arm by a torsion spring, the discharge plate is fixedly connected to the inner wall of the mixing drum, the bottom surface of the rocker arm contacts the top surface of the discharge plate, and discharge holes are provided on the discharge plate, the mixing drum, and the waste bin. The surface of the scraper contacts the inner wall of the mixing drum, and the main shaft is rotatably connected to the inner wall of the discharge plate. The cleaning mechanism also includes a reciprocating screw, a slider, an elastic telescopic rod, a scraper, a groove plate, a friction wheel, and a one-way... The system comprises a wheel, a sliding column, and a collecting plate. The second reciprocating screw is rotatably connected to the inner wall of the main shaft. The slider is movably connected to the circumferential surface of the second reciprocating screw. The second elastic telescopic rod is fixedly connected to the top of the slider. The scraper is fixedly connected to the end of the second elastic telescopic rod away from the slider. The grooved plate is fixedly connected to the circumferential surface of the main shaft. The friction wheel is fixedly connected to the end of the second reciprocating screw away from the main shaft. The one-way wheel is rotatably connected to the inner wall of the grooved plate. The sliding column is fixedly connected to the front side of the scraper. The collecting plate is fixedly connected to the circumferential surface of the main shaft. The right side of the slider is in contact with the left side of the grooved plate. The right side of the second elastic telescopic rod is in contact with the left side of the grooved plate. The inner wall of the scraper is in contact with the surface of the collecting plate. The bottom surface of the collecting plate is in contact with the drain. The top surfaces of the material plates are in contact with each other, and the bottom surface of the trough plate is in contact with the top surface of the material leakage plate. A circular groove is formed on the surface of the trough plate, and the circumferential surface of the sliding column is in contact with the inner wall of the trough plate. While the main shaft rotates, it drives the stirring plate to rotate, which in turn drives the rocker arm to rotate along the circumferential surface of the main shaft. The rocker arm drives the scraper to rotate along the circumferential surface of the main shaft. Due to the torsion spring hinged between the stirring plate and the rocker arm, the rocker arm drives the scraper to rotate close to the inner wall of the mixing drum, thus achieving stirring of the wastewater after the addition of the reagent. This ensures that the wastewater is fully mixed and reacted with the reagent within the device, improving the working quality of the device. Simultaneously, the main shaft drives the second reciprocating screw to rotate, which in turn drives the friction wheel to rotate on the top surface of the material leakage plate. The rotation of the friction wheel further drives the second reciprocating screw... The reciprocating screw rotates on the inner wall of the main shaft, causing the slider to move forward. The slider then moves the elastic telescopic rod forward, which in turn moves the scraper forward. The scraper moves the sliding column forward. As the scraper moves forward, the elastic telescopic rod rebounds and pulls the scraper forward along the bottom of the groove on the slot plate. When the scraper moves within the working range of the one-way wheel, the reciprocating screw continues to rotate, causing the scraper to move outward. At this time, the scraper moves the sliding column outward, causing the one-way wheel to rotate counterclockwise. When the sliding column moves out of the working range of the one-way wheel, the one-way wheel resets due to the torsion spring hinged between the slot plate and the one-way wheel. The scraper then moves backward. Because of the plane on the right side of the one-way wheel, it only has unidirectional rotation capability.The scraper moves backward and upward along the inclined surface of the one-way wheel, stretching the elastic telescopic rod two upward, and then resets along the top of the U-shaped groove on the surface of the trough plate. The collection plate sliding on the surface of the leakage plate collects the precipitate after the wastewater reaction and directs it from the scraper to the leakage trough opened on the leakage plate, preventing excessive accumulation of precipitate inside the device from affecting subsequent treatment results.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This activated carbon municipal wastewater treatment device, through the coordinated operation of the cylinder plate, screen cylinder, cylinder sleeve, movable cylinder, elastic telescopic rod, wedge, reciprocating screw, brush, limit plate, handle, stirring rod, and cylinder wall, continuously turns and stirs the activated carbon placed in the screen cylinder during equipment startup, ensuring that the activated carbon can be fully utilized in the device, reducing subsequent production costs. The wedge sliding on the inner wall of the cylinder can be pulled out of the entire sleeve after the device finishes production, facilitating subsequent replacement of activated carbon and improving the working efficiency of the device.

[0009] 2. This activated carbon municipal wastewater treatment device, through the coordinated operation of the top plate, discharge plate, groove wheel, limit cover, chemical box, delivery pipe, and pull rod, achieves intermittent water discharge after the device completes activated carbon filtration by pulling the discharge plate when the wedge descends. This ensures complete treatment of wastewater by activated carbon. The pull rod fixed to the side of the discharge plate drives the groove wheel to rotate when the discharge plate is opened, adding the chemical treatment agent in the delivery pipe. This achieves intermittent dosing of the device and reduces secondary pollution of wastewater caused by chemical addition.

[0010] 3. This activated carbon municipal wastewater treatment device, through the coordinated operation of the mixing drum, mixing plate, waste bin, rocker arm, scraper, discharge plate, reciprocating screw two, slider, elastic telescopic rod two, scraper block, trough plate, friction wheel, one-way wheel, sliding column and collection plate, achieves the mixing of wastewater after the addition of chemicals, ensuring that the wastewater is fully mixed and reacted with the chemicals in the device, thus improving the working quality of the device. The collection plate sliding on the surface of the discharge plate collects the precipitate after the wastewater reaction and sends it to the discharge trough opened on the discharge plate by the scraper block, preventing excessive accumulation of precipitate inside the device from affecting the subsequent treatment effect.

The cylinder plate 401 is rotatably connected to the circumferential surface of the sleeve 403, and the bottom end of the sleeve 403 contacts the inner wall of the movable cylinder 404. A roller is fixedly connected to the end of the reciprocating screw 407 away from the main shaft 3, and the circumferential surface of the roller contacts the top surface of the cylinder plate 401. The brush 408 contacts the surface of the limiting plate 409. The inner wall of the cylinder 412 is provided with a one-way spiral groove. A protrusion is provided on the end of the reciprocating screw 407 away from the main shaft 3, and the protrusion is slidably connected in the one-way spiral groove on the inner wall of the cylinder 412. A sliding groove is provided on the inner wall of the cylinder 412, and the depth of the sliding groove is less than that of the one-way spiral groove. The wedge 406 is in contact with the inner wall of the cylinder 412. When the equipment is started, the activated carbon placed in the screen cylinder 402 is continuously turned over and stirred, ensuring that the activated carbon can be fully utilized in the device and reducing the subsequent production cost of the device.

[0015] The medicine box 6 includes a top plate 601, a water discharge plate 602, a grooved wheel 603, a limiting cover 604, a medicine box 605, a medicine delivery pipe 606, and a pull rod 607. The top plate 601 is fixedly connected to the inner wall of the housing 1. The water discharge plate 602 is slidably connected to the inner wall of the top plate 601 by a spring, realizing intermittent water discharge after the activated carbon filtration is completed, ensuring complete treatment of wastewater by the activated carbon. The medicine box 605 is fixedly connected to the outer side of the housing 1. The medicine delivery pipe 606 is fixedly connected to the inner wall of the medicine box 605. The grooved wheel 603 is rotatably connected to the inner wall of the medicine box 605. The limiting cover 604 is fixedly connected to the housing. The inner wall of the main shaft 3 is connected to the surface of the discharge plate 602 by a pull rod 607. The bottom surface of the discharge plate 602 is in contact with the top surface of the limit cover 604. The circumferential surface of the pull rod 607 is in contact with the inner wall of the groove wheel 603. The discharge plate 602 is set on the movement trajectory of the wedge 406. The discharge plate 602 is rotatably connected to the circumferential surface of the main shaft 3. When the discharge plate 602 is pulled open, the pull rod 607 fixed on the side of the discharge plate 602 drives the groove wheel 603 to rotate, adding the chemical treatment agent in the delivery pipe 606 into the device. This realizes the intermittent dosing of the device and reduces the secondary pollution of sewage caused by the addition of the agent.

[0016] Working principle: When the equipment starts, the main shaft 3 rotates, driving the movable cylinder 404 to move upward. The movable cylinder 404 drives the screen cylinder 402 to move upward, and the screen cylinder 402 drives the cylinder plate 401 to move upward. At the same time as the screen cylinder 402 moves upward, the reciprocating screw 407 drives the sleeve 403 to rotate along the circumference of the main shaft 3. The rotation of the reciprocating screw 407 causes the rollers on the reciprocating screw 407 to contact and rotate with the top of the movable cylinder 404. The rotation of the rollers causes the reciprocating screw 407 to rotate on the inner wall of the sleeve 403. The rotation of the reciprocating screw 407 on the inner wall of the sleeve 403 also drives the brush 408 to move along the side of the limiting plate 409 on the top surface of the cylinder plate 401. The rotation of the sleeve 403 drives the stirring rod 411 to move along the main shaft 3. The circumferential surface of the screen rotates, continuously turning and stirring the activated carbon placed in the screen cylinder 402 when the equipment starts up. This ensures that the activated carbon is fully utilized within the device, reducing subsequent production costs. When the activated carbon needs to be replaced, the top cover 5 is opened and a worker pulls the handle 410. The handle 410 moves the limiting plate 409 upward, which in turn moves the sleeve 403 upward. The sleeve 403 then moves the screen cylinder 402 upward until it is completely pulled out. The newly prepared activated carbon is then placed into the screen cylinder 402. The wedge 406, which slides on the inner wall of the cylinder 412, can pull out the entire screen cylinder 402 after the device finishes production, facilitating subsequent replacement of activated carbon and improving the device's working efficiency.

[0017] When the main shaft 3 rotates, driving the movable cylinder 404 downwards, the movable cylinder 404 drives the elastic telescopic rod 405 downwards, which in turn drives the wedge 406 downwards. When the wedge 406 moves downwards to the working range of the discharge plate 602, it drives the discharge plate 602 to move outwards along the inclined surface set on it. This achieves intermittent water discharge after the activated carbon filtration is completed, ensuring complete treatment of wastewater by the activated carbon. Simultaneously, as the discharge plate 602 moves outwards... The discharge plate 602 drives the pull rod 607 to move outward. The pull rod 607 drives the grooved wheel 603 to rotate inward on the inner wall of the delivery pipe 606. A portion of the medicine in the delivery pipe 606 is pushed out into the device through the notch on the grooved wheel 603. The pull rod 607, which is fixed to the side of the discharge plate 602, drives the grooved wheel 603 to rotate when the discharge plate 602 is pulled open, adding the chemical treatment agent in the delivery pipe 606 into the device. This realizes the intermittent dosing of the device and reduces the secondary pollution of sewage caused by the addition of the agent.

The material discharge plate 706, the mixing drum 701, and the waste bin 703 are all provided with discharge holes. The surface of the scraper 705 is in contact with the inner wall of the mixing drum 701. The main shaft 3 is rotatably connected to the inner wall of the material discharge plate 706, which realizes the stirring of the wastewater after the addition of the agent, ensuring that the wastewater is fully mixed and reacted with the agent in the device, thus improving the working quality of the device. The cleaning mechanism 7 also includes a reciprocating screw 707, a slider 708, an elastic telescopic rod 709, a scraper 710, a groove plate 711, a friction wheel 712, a one-way wheel 713, a sliding column 714, and a collection plate 715. The reciprocating screw 707 is rotatably connected to the inner wall of the main shaft 3. The slider 708 is movably connected to the circumferential surface of the reciprocating lead screw 707. The elastic telescopic rod 709 is fixedly connected to the top of the slider 708. The scraper 710 is fixedly connected to the end of the elastic telescopic rod 709 away from the slider 708. The groove plate 711 is fixedly connected to the circumferential surface of the main shaft 3. The friction wheel 712 is fixedly connected to the end of the reciprocating lead screw 707 away from the main shaft 3. The one-way wheel 713 is rotatably connected to the inner wall of the groove plate 711. The sliding column 714 is fixedly connected to the front side of the scraper 710. The collecting plate 715 is fixedly connected to the circumferential surface of the main shaft 3. The right side of the slider 708 is in contact with the left side of the groove plate 711, and the elastic telescopic rod is in contact with the left side of the groove plate 711. The right side of rod 709 is in contact with the left side of trough plate 711, the inner wall of scraper 710 is in contact with the surface of collection plate 715, the bottom surface of collection plate 715 is in contact with the top surface of leakage plate 706, the bottom surface of trough plate 711 is in contact with the top surface of leakage plate 706, a spiral groove is provided on the surface of trough plate 711, the circumferential surface of sliding column 714 is in contact with the inner wall of trough plate 711, the collection plate 715 sliding on the surface of leakage plate 706 collects the precipitate after the sewage reaction and sends it from scraper 710 to the leakage groove opened on leakage plate 706, preventing the accumulation of too much precipitate inside the device from affecting the subsequent treatment effect.

[0019] Working principle: While the main shaft 3 rotates, it drives the stirring plate 702 to rotate. The stirring plate 702 drives the rocker arm 704 to rotate along the circumference of the main shaft 3. The rocker arm 704 drives the scraper 705 to rotate along the circumference of the main shaft 3. Due to the torsion spring hinged between the stirring plate 702 and the rocker arm 704, the rocker arm 704 drives the scraper 705 to rotate close to the inner wall of the mixing drum 701, thus achieving stirring of the wastewater after the addition of chemicals. This ensures that the wastewater is fully mixed and reacted with the chemicals within the device, improving the working quality of the device. Simultaneously with the rotation of the main shaft 3... At the same time, the main shaft 3 drives the reciprocating screw 707 to rotate, the reciprocating screw 707 drives the friction wheel 712 to rotate on the top surface of the material feed plate 706, the rotation of the friction wheel 712 drives the reciprocating screw 707 to rotate on the inner wall of the main shaft 3, the rotation of the reciprocating screw 707 drives the slider 708 to move forward, the slider 708 drives the elastic telescopic rod 709 to move forward, the elastic telescopic rod 709 drives the scraper 710 to move forward, the scraper 710 drives the sliding column 714 to move forward, and at the same time the scraper 710 moves forward, the elastic telescopic rod 709... 709 rebounds and pulls scraper 710 forward along the bottom of the groove on the slot plate 711. When scraper 710 moves within the working range of one-way wheel 713, reciprocating screw 707 continues to rotate and drives scraper 710 to move outward. At this time, scraper 710 drives slide column 714 to move outward, and slide column 714 drives one-way wheel 713 to rotate counterclockwise. When slide column 714 moves out of the working range of one-way wheel 713, due to the action of the torsion spring hinged between slot plate 711 and one-way wheel 713, one-way wheel 713 returns to its original position. The scraper block 710 moves backward. Due to the plane on the right side of the one-way wheel 713, the one-way wheel 713 can only rotate in one direction. The scraper block 710 moves backward and moves upward along the inclined surface of the one-way wheel 713, stretching the elastic telescopic rod 709. It then resets along the top of the groove on the surface of the trough plate 711. The collection plate 715 sliding on the surface of the leakage plate 706 collects the sediment after the sewage reaction and sends it from the scraper block 710 to the leakage trough opened on the leakage plate 706, preventing excessive accumulation of sediment inside the device from affecting the subsequent treatment effect.
