Description

A dosing device for water pollution treatment Technical Field

[0001] This invention relates to the field of water pollution control technology, specifically to a dosing device for water pollution control. Background Technology

[0002] Water pollution control can effectively remove pollutants from water, prevent waterborne diseases, significantly reduce the risks caused by drinking polluted water, restore the ecological balance of water bodies, reduce the toxicity of industrial wastewater and agricultural runoff to aquatic organisms, and maintain the health of ecosystems such as rivers and lakes.

[0003] Patent CN216987435U discloses a dosing device for water pollution treatment, including a frame with three horizontally mounted mixing tanks arranged in an inverted triangle. The bottoms of the two upper mixing tanks are connected to the tops of the lower mixing tanks via pipes. A conveying pipe is connected to the bottom of the lower mixing tank. Each mixing tank contains a horizontally mounted stirring shaft with stirring blades. The same end of all three stirring shafts extends out of the mixing tanks and is connected to a common drive device. The bottom of the frame is equipped with pulleys and a stop mechanism. Compared with existing technologies, this patent… The device uses a drive motor to simultaneously drive the stirring blades in three mixing tanks to mix the drug. The two upper mixing tanks pre-stir and disperse the drug, and then the lower mixing tank performs secondary mixing before feeding. This achieves uniform drug dosing, facilitates mobile operation, saves manpower and resources, and fully utilizes the drug's effects for effective river treatment. However, the above-mentioned device is difficult to achieve large-scale drug dosing during operation, resulting in a limited dosing range and affecting the treatment of pollutants. Therefore, a drug dosing device for water pollution treatment is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a dosing device for water pollution treatment, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a dosing device for water pollution treatment, comprising a box, a sliding wheel provided at the bottom of the box, a dosing mechanism provided on the inner wall of the box, an emergency rescue mechanism provided above the dosing mechanism, and an auxiliary mechanism provided on the front side of the box.

[0006] Preferably, a reciprocating screw is rotatably connected to the inner wall of the fixed block two. A helical gear is fixedly connected to the bottom end of the reciprocating screw one. The helical gear two meshes with the fixed block two. A movable frame is movably connected to the circumferential surface of the reciprocating screw one. The surface of the movable frame is in contact with the inner wall of the box. When the device is running, the slide rail wheel drives the device to move on the electric slide rail next to the biological treatment tank. The slide rail wheel drives the box to move. The box drives the roller to rotate in close contact with the surface of the electric slide rail. The sprayer driven by the slide rail wheel realizes the large-scale dosing of chemicals to the sewage in the biological treatment tank, expands the treatment range of the device, avoids excessive accumulation of chemicals in one place, which would make the sewage difficult to treat effectively, and improves the working efficiency of the device.

[0007] Preferably, the dosing mechanism further includes a rack, which is fixedly connected to the inner wall of the movable frame. A second rotating shaft is rotatably connected to the inner wall of the housing. A sprayer is fixedly connected to the circumferential surface of the second rotating shaft, and a spur gear is fixedly connected to the circumferential surface of the second rotating shaft. The rack and the spur gear mesh with each other, and the surface of the spur gear contacts the side of the sprayer. The spur gear is hinged to the inner wall of the housing by a torsion spring. A bottom plate is fixedly connected to the inner wall of the housing, and a medicine box is fixedly connected to the top surface of the bottom plate. A roller drives the first rotating shaft to rotate on the inner wall of the fixed block. The rotation of the first rotating shaft drives the first helical gear to rotate, which in turn drives the meshing helical gear second to rotate. The second helical gear drives the first reciprocating screw to rotate, and the first reciprocating screw drives the movable frame to rotate on the circumference of the first reciprocating screw. The device moves up and down repeatedly. When the movable frame moves upward, it drives the rack upward. When the rack moves to the working range of the spur gear, the rack meshes with the spur gear and drives the spur gear to rotate clockwise. The rotation of the spur gear drives the second rotating shaft to rotate clockwise, and the rotation of the second rotating shaft drives the sprayer to rotate clockwise. When the movable frame moves downward, it drives the rack downward. The rack meshes with the spur gear and drives the spur gear to rotate counterclockwise. The rotation of the spur gear drives the second rotating shaft to rotate counterclockwise, and the rotation of the second rotating shaft drives the sprayer to rotate counterclockwise. The rotating sprayer reciprocates during device operation, realizing the adjustment of the sprayer's dosing angle during device operation. This reduces the dead angle of dosing in the biological treatment tank and prevents wastewater from being difficult to treat effectively due to limited dosing range.

[0008] Preferably, the emergency rescue mechanism includes a water collection box, the inner wall of which has a drain outlet, a support plate fixedly connected to the bottom surface of the water collection box, the support plate being slidably connected to the inner wall of the box, and a sealing plate fixedly connected to the bottom surface of the support plate.

[0009] Preferably, a sealing ring is provided on the bottom surface of the sealing plate to ensure the airtightness of the sealing plate. The medicine box is set on the movement trajectory of the sealing plate. A limit block is fixedly connected to the surface of the support plate. A pivot pin is hinged to the inner wall of the box by a torsion spring. The top surface of the pivot pin is in contact with the bottom surface of the limit block. During operation, if heavy rain occurs, the rainwater is collected by the water collection box to determine whether the device should operate normally. If the water in the water collection box cannot be discharged in time through the drainage hole in the water collection box, the rainwater is too heavy. In this case, the weight of the rainwater in the water collection box is greater than the force of the torsion spring hinged between the pivot pin and the inner wall of the box. The water collection box moves the support plate downwards, which in turn moves the limiting block downwards. The limiting block moves downwards and rotates the pivot pin. Simultaneously, the limiting block moves the sealing plate downwards. When the sealing plate moves downwards until it seals the opening at the top of the medicine tank, the water pump inside the medicine tank stops working because it cannot take in air. At this point, the device stops working. The support plate, which slides inside the tank, moves the sealing plate to seal the medicine tank during heavy rain, thus stopping the device from operating. This achieves the protective effect of the device, preventing the medicine from being diluted due to excessive rainfall, which would weaken the treatment effect of the medicine and avoid waste of medicine, thereby improving the economic efficiency of the device.

[0010] Preferably, the emergency rescue mechanism further includes a convex plate, which is fixedly connected to the bottom of the water collection box. A carbon box is fixedly connected to the front side of the box, and the carbon box contains activated carbon powder. A cover plate is hinged to the inner wall of the carbon box by a torsion spring. The cover plate is set on the movement trajectory of the convex plate. As the water collection box descends, it drives the convex plate to move downward. When the convex plate moves to the working position of the cover plate, it squeezes and drives the cover plate to rotate. At this time, the carbon box opens, and the activated carbon powder inside the carbon box is put into the biochemical pool. The activated carbon powder in the carbon box is poured into the biochemical pool by the rotating cover plate squeezed by the convex plate. This achieves the remedial effect of the imbalance of pollutants in the pool during heavy rain, and prevents the pollutant environment in the biochemical pool from becoming unbalanced due to rainwater when the device stops operating, making it more difficult to treat after the rain stops.

[0011] Preferably, the auxiliary mechanism includes a fixing plate, which is fixedly connected to the left side of the box body. A limit strip is fixedly connected to the side of the box body. A fixing block three is fixedly connected to the surface of the limit strip. A liquid wheel is rotatably connected to the bottom surface of the fixing block three. The circumferential surface of the liquid wheel is in contact with the wall of the biochemical tank.

[0012] Preferably, the inner wall of the fixed block three is rotatably connected to the reciprocating screw two. The bottom end of the reciprocating screw two is fixedly connected to the top surface of the liquid wheel. A slider is movably connected to the circumferential surface of the reciprocating screw two. A rocker arm is rotatably connected to the inner wall of the slider. When the device moves, the box moves the fixed plate, the fixed plate moves the limiting strip, the limiting strip moves the fixed block three, and the fixed block three moves the liquid wheel. When the liquid wheel moves, it rotates close to the inside of the biological tank and drives the reciprocating screw two to rotate. The rotation of the reciprocating screw two causes the slider to slide up and down on the circumferential surface of the reciprocating screw two. The movement of the slider causes the rocker arm to rotate and pull the top block to slide on the circumferential surface of the sliding column. When the top block slides forward, the top block drives the push plate to move forward and rotate. The push plate pulled by the rocker arm pushes the liquid clumps that may accumulate during the spraying process toward the center of the tank during the operation of the device, realizing the mixing effect of the device, making the liquid react more evenly in the biological tank, and improving the working quality of the device.

[0013] Preferably, the auxiliary mechanism further includes a sliding column, on the circumferential surface of which a top block is slidably connected. An arc plate is fixedly connected to the front side of the top block, and a push plate is rotatably connected to the side of the top block. The arc plate is used to limit the rotation angle of the push plate to prevent it from failing to reset properly due to excessive rotation angle. An agitator is provided on the inner wall of the push plate. As the push plate rotates, the agitator on the inner wall of the push plate rotates due to the friction of the sewage. The rotation of the push plate drives the agitator to rotate, thereby achieving the effect of breaking up the accumulated drug clumps. This further improves the mixing efficiency of the device for sewage and drug, allowing the sewage in the biological treatment tank to fully react with the drug, and further improves the working quality of the device.

[0014] The present invention, by adopting the above-mentioned technical solution, can bring the following beneficial effects: 1. The dosing device for water pollution treatment, through the coordinated operation of rotating shaft one, fixed block one, roller, helical gear one, fixed block two, helical gear two, reciprocating screw one, movable frame, rack, rotating shaft two, sprayer, spur gear, base plate and medicine tank, and the sprayer driven by the slide rail wheel, realizes the large-scale dosing of chemicals on sewage in the biological treatment tank, expands the treatment range of the device, avoids excessive accumulation of chemical solution in a certain place, thus preventing sewage from being difficult to treat effectively, and improves the working efficiency of the device. The rotating sprayer reciprocates during the operation of the device, realizing the adjustment of the sprayer's dosing angle during the operation of the device, reducing the dosing dead angle in the biological treatment tank, and preventing sewage from being difficult to treat effectively due to the limited dosing range.

[0015] 2. This dosing device for water pollution treatment works in concert with a water collection box, support plate, sealing plate, limiting block, rotating pin, convex plate, carbon box, and cover plate. The support plate, sliding inside the box, drives the sealing plate to seal the tank during heavy rain, stopping the device and protecting it. This prevents the chemicals from being diluted due to excessive rainfall, thus reducing their effectiveness and preventing waste. The convex plate presses against the rotating cover plate, pouring activated carbon powder from the carbon box into the biological treatment tank. This remediates any imbalance of pollutants in the tank during heavy rain, preventing the tank from becoming unbalanced due to rainwater when the device stops operating, making treatment even more difficult after the rain stops.

[0016] 3. This dosing device for water pollution treatment, through the coordinated operation of a fixed plate, limiting strip, fixed block three, liquid wheel, reciprocating screw two, slider, rocker arm, sliding column, top block, arc plate, push plate, and agitator fan, achieves a mixing effect by having the push plate pulled by the rocker arm push the possible aggregated liquid clumps towards the center of the pool during the operation of the device. This results in a more uniform reaction of the liquid in the biological treatment tank, improving the working quality of the device. The rotation of the push plate drives the agitator fan to disperse the aggregated liquid clumps, further improving the mixing efficiency of the device for wastewater and liquid, allowing the wastewater in the biological treatment tank to fully react with the liquid, further improving the working quality of the device.

[0019] 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.

[0020] Please refer to Figures 1-8. One embodiment of the present invention is as follows: a dosing device for water pollution treatment includes a housing 1, a sliding wheel 2 at the bottom of the housing 1, a dosing mechanism 3 on the inner wall of the housing 1, an emergency mechanism 4 above the dosing mechanism 3, and an auxiliary mechanism 5 on the front side of the housing 1. The dosing mechanism 3 includes a rotating shaft 31, which is rotatably connected to the inner wall of the housing 1. A fixing block 32 is fixedly connected to the inner wall of the housing 1. The circumferential surface of the rotating shaft 31 is rotatably connected to the inner wall of the fixing block 32. A roller 33 is fixedly connected to the circumferential surface of the rotating shaft 31. A helical gear 34 is fixedly connected to the front end of the rotating shaft 31. A fixing block 35 is fixedly connected to the inner wall of the housing 1. The sprayer 311 driven by the sliding wheel 2 realizes large-scale dosing of chemicals on sewage in the biological treatment tank, expands the treatment range of the device, avoids excessive accumulation of chemicals in one place, thus preventing sewage from being difficult to treat effectively, and improves the working efficiency of the device.

[0021] A reciprocating screw 37 is rotatably connected to the inner wall of the fixed block 35. A helical gear 36 is fixedly connected to the bottom end of the reciprocating screw 37. The helical gear 36 meshes with the fixed block 35. A movable frame 38 is movably connected to the circumferential surface of the reciprocating screw 37. The surface of the movable frame 38 is in contact with the inner wall of the housing 1.

[0022] The dosing mechanism 3 also includes a rack 39, which is fixedly connected to the inner wall of the movable frame 38. A second rotating shaft 310 is rotatably connected to the inner wall of the housing 1. A sprayer 311 is fixedly connected to the circumferential surface of the second rotating shaft 310. A spur gear 312 is fixedly connected to the circumferential surface of the second rotating shaft 310. The rack 39 and the spur gear 312 mesh with each other. The surface of the spur gear 312 contacts the side of the sprayer 311. The spur gear 312 is hinged to the inner wall of the housing 1 by a torsion spring. A bottom plate 313 is fixedly connected to the inner wall of the housing 1. A medicine tank 314 is fixedly connected to the top surface of the bottom plate 313. The rotating sprayer 311 reciprocates during device operation, realizing the adjustment of the dosing angle of the sprayer 311 during device operation, reducing the dead angle of dosing in the biological treatment tank, and preventing the wastewater from being difficult to treat effectively due to the limited dosing range.

[0023] The emergency medical device 4 includes a water collection box 41 with a drain outlet on its inner wall. A support plate 42 is fixedly connected to the bottom of the water collection box 41. The support plate 42 is slidably connected to the inner wall of the box 1. A sealing plate 43 is fixedly connected to the bottom of the support plate 42. The support plate 42, which slides inside the box 1, drives the sealing plate 43 to seal the medicine box 314 during heavy rain, thus stopping the device from operating. This achieves the protective effect of the device, preventing the medicine from being diluted due to excessive rainfall, thereby weakening the treatment effect of the medicine, avoiding waste of medicine, and improving the economy of the device.

[0024] A sealing ring is provided on the bottom surface of the sealing plate 43 to ensure the airtightness of the sealing plate 43. The medicine box 314 is set on the movement trajectory of the sealing plate 43. A limit block 44 is fixedly connected to the surface of the support plate 42. A pivot pin 45 is hinged to the inner wall of the box body 1 by a torsion spring. The top surface of the pivot pin 45 is in contact with the bottom surface of the limit block 44.

[0025] The emergency rescue device 4 also includes a convex plate 46, which is fixedly connected to the bottom of the water collection box 41. A carbon box 47 is fixedly connected to the front side of the box 1. The carbon box 47 contains activated carbon powder. The inner wall of the carbon box 47 is hinged to a cover plate 48 by a torsion spring. The cover plate 48 is set on the movement trajectory of the convex plate 46. The convex plate 46 squeezes the rotating cover plate 48 to pour the activated carbon powder in the carbon box 47 into the biochemical pool. This achieves the remedial effect of the imbalance of pollutants in the pool during heavy rain, and prevents the pollutant environment in the biochemical pool from becoming unbalanced due to rainwater when the device stops operating, making it more difficult to treat after the rain stops.

[0026] Working Principle: During operation, the device moves along an electric slide rail next to the biological treatment tank, driven by the slide rail wheel 2. The slide rail wheel 2 moves the housing 1, which in turn drives the roller 33 to rotate against the surface of the electric slide rail. The sprayer 311, driven by the slide rail wheel 2, enables large-scale dosing of chemicals into the sewage in the biological treatment tank, expanding the treatment range of the device and preventing excessive accumulation of chemicals in one place, which would hinder effective sewage treatment and improve the working efficiency of the device. The roller 33 drives the rotating shaft 31 to rotate on the inner wall of the fixed block 32. The rotation of the rotating shaft 31 drives the helical gear 34 to rotate, which in turn drives the meshing helical gear 36 to rotate. The helical gear 36 drives the reciprocating screw 37 to rotate, which in turn drives the movable frame 38 to move up and down on the circumferential surface of the reciprocating screw 37. When the movable frame 38 moves upward, it drives the rack. When rack 39 moves upward, and it reaches the working range of spur gear 312, rack 39 meshes with spur gear 312, causing spur gear 312 to rotate clockwise. The rotation of spur gear 312 causes shaft 2 310 to rotate clockwise, and shaft 2 310 causes sprayer 311 to rotate clockwise. When movable frame 38 moves downward, movable frame 38 causes rack 39 to move downward, rack 39 meshes with spur gear 312, causing spur gear 312 to rotate counterclockwise. The rotation of spur gear 312 causes shaft 2 310 to rotate counterclockwise, and shaft 2 310 causes sprayer 311 to rotate counterclockwise. The rotating sprayer 311 reciprocates during device operation, realizing the adjustment of the sprayer 311's dosing angle during device operation, reducing the dosing dead angle in the biological treatment tank, and preventing the wastewater from being difficult to treat effectively due to the limited dosing range.

[0027] During device operation, if heavy rain occurs, the water collection box 41 collects rainwater to determine whether the device should operate normally. If the water in the water collection box 41 cannot be discharged in time through the drainage hole, the rainwater is too heavy. At this time, because the weight of the rainwater is greater than the force of the torsion spring hinged between the pivot pin 45 and the inner wall of the box 1, the water collection box 41 drives the support plate 42 to move downward. The support plate 42 drives the limiting block 44 to move downward. The limiting block 44 moves downward and drives the pivot pin 45 to rotate. At the same time, the limiting block 44 drives the sealing plate 43 to move downward. When the sealing plate 43 moves downward until it seals the opening at the top of the medicine box 314, the water pump installed inside the medicine box 314 stops working because it cannot take in air. At this time, the device stops working. The support plate 42 sliding inside the box 1 drives the sealing plate 43 to release water during heavy rain. The medicine tank 314 is sealed, stopping the device from operating and protecting it from dilution due to excessive rainfall, which would weaken the treatment effect and prevent waste. This improves the economic efficiency of the device. As the water collection box 41 descends, it moves the convex plate 46 downwards. When the convex plate 46 reaches the working position of the cover plate 48, it squeezes and rotates the cover plate 48. At this time, the carbon box 47 opens, releasing the activated carbon powder inside into the biological treatment tank. The convex plate 46 squeezes and rotates the cover plate 48, pouring the activated carbon powder from the carbon box 47 into the biological treatment tank. This remedial effect addresses the imbalance of pollutants in the tank during heavy rain, preventing the imbalance caused by rainwater from making the pollutants in the biological treatment tank even more difficult to treat after the rain stops.

[0028] Please refer to Figures 1-8. Based on the above embodiments, in another embodiment of the present invention, the auxiliary mechanism 5 includes a fixing plate 51, which is fixedly connected to the left side of the box 1. A limiting strip 52 is fixedly connected to the side of the box 1. A fixing block 53 is fixedly connected to the surface of the limiting strip 52. A liquid wheel 54 is rotatably connected to the bottom surface of the fixing block 53. The circumferential surface of the liquid wheel 54 is in contact with the wall of the biochemical tank.

[0029] The inner wall of the fixed block 3 53 is rotatably connected to the reciprocating screw 2 55. The bottom end of the reciprocating screw 2 55 is fixedly connected to the top surface of the liquid wheel 54. The slider 56 is movably connected to the circumferential surface of the reciprocating screw 2 55. The inner wall of the slider 56 is rotatably connected to the rocker arm 57. The push plate 511 pulled by the rocker arm 57 pushes the liquid clumps that may accumulate during the spraying process toward the center of the pool during the operation of the device, thereby achieving the mixing effect of the device and making the liquid react more evenly in the biochemical pool, thus improving the working quality of the device.

[0030] The auxiliary mechanism 5 also includes a sliding column 58, on which a top block 59 is slidably connected. An arc plate 510 is fixedly connected to the front side of the top block 59, and a push plate 511 is rotatably connected to the side of the top block 59. The arc plate 510 is used to limit the rotation angle of the push plate 511 to prevent it from failing to reset properly due to excessive rotation angle. An agitator 512 is provided on the inner wall of the push plate 511. The rotation of the push plate 511 drives the agitator 512 to rotate, thereby breaking up the aggregated drug solution clumps and further improving the mixing efficiency of the device for sewage and drug solution. This allows the sewage in the biochemical tank to fully react with the drug solution, further improving the working quality of the device.

[0031] Working principle: As the device moves, the housing 1 moves the fixing plate 51, which in turn moves the limiting strip 52. The limiting strip 52 then moves the fixing block 53, which in turn moves the liquid wheel 54. Simultaneously, the liquid wheel 54 rotates close to the interior of the biochemical tank, driving the reciprocating screw 55 to rotate. The rotation of the reciprocating screw 55 causes the slider 56 to slide up and down on its circumferential surface. The movement of the slider 56 causes the rocker arm 57 to rotate, pulling the top block 59 to slide on the circumferential surface of the sliding column 58. When the top block 59 slides forward, it drives the push plate 511 to move forward and rotate. The push plate 511, pulled by the rocker arm 57, pushes any clumps of pesticide solution that may accumulate during spraying toward the center of the tank during operation, achieving a mixing effect and making the pesticide solution react more evenly in the biological treatment tank, thus improving the working quality of the device. Simultaneously with the rotation of the push plate 511, the agitator 512 installed on the inner wall of the push plate 511 rotates due to the friction of the sewage. The rotation of the push plate 511 drives the agitator 512 to rotate, breaking up any clumps of pesticide solution that accumulate, further improving the mixing efficiency of the sewage and pesticide solution. This ensures that the sewage in the biological treatment tank can fully react with the pesticide solution, further enhancing the working quality of the device.
