Description

Technical Field

[0001] This invention relates to the field of landfill wastewater treatment technology, and more specifically, to a landfill wastewater treatment device with an oxygenation function. Background Technology

[0002] Landfills typically use a layered soil covering method to treat waste, piling up a layer of waste and then covering it with a layer of soil. This easily reduces pollution. There are two types of landfilling: dumping, which involves digging an open pit in the ground and burying the waste in it, with various animals (rats and birds) gathering around the pit. (This is the common perception of landfills.) Landfilling, on the other hand, involves constructing carefully designed facilities underground or above ground to isolate the waste from the surrounding environment (groundwater, air, and rainwater). This isolation is achieved through a bottom liner and daily soil covering. Sanitary landfills use a clay liner to isolate the waste from the environment. Municipal solid waste landfills use a synthetic (plastic) liner to isolate the waste from the environment. The purpose of landfilling is to bury waste, separating it from groundwater, keeping it dry, and preventing contact with air. Under these conditions, the waste will not decompose significantly. Landfills differ from composting heaps, whose purpose is to rapidly decompose the buried waste.

[0003] Landfills often generate a large amount of wastewater, which typically requires wastewater treatment equipment. The usual method involves feeding the wastewater into the treatment tank of the equipment, adding wastewater treatment chemicals, and then mixing the wastewater and chemicals through agitation. However, traditional wastewater treatment equipment has a relatively simple agitation structure, relying solely on a motor to rotate the agitator in one direction. This often results in uneven mixing of the wastewater and chemicals. Furthermore, it lacks a single function, specifically oxygenation. Therefore, we provide a landfill wastewater treatment device with an oxygenation function. Summary of the Invention

[0004] The purpose of this invention is to provide a landfill wastewater treatment device with oxygenation function to solve the problems mentioned in the background art above: Traditional wastewater treatment devices have relatively simple mixing structures, which simply use a motor to drive the mixing rod to rotate in one direction. This can easily lead to uneven mixing between wastewater and wastewater treatment agents. In addition, they have limited functionality and do not have an oxygenation function.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A landfill wastewater treatment device with oxygenation function includes a treatment box. A fixed plate is fixedly connected inside the treatment box. A first groove is formed on the upper surface of the fixed plate. A first slider is slidably connected inside the first groove. A movable block is fixedly connected to the top of the first slider. A rotating plate is rotatably connected inside the treatment box and above the movable block. A second groove is formed inside the rotating plate. A sliding rod is slidably connected inside the second groove. The sliding rod vertically passes through the movable block and extends to the bottom of the movable block. The sliding rod is fixedly connected to the movable block. A stirring rod is rotatably connected inside the sliding rod. A transmission mechanism is provided above the stirring rod. An oxygenation mechanism is provided inside the movable block.

[0006] Preferably, the first groove is a regular hexagonal structure, and there are six first sliders in total, which are symmetrically distributed.

[0007] Preferably, a fourth sliding groove is provided on the lower surface of the fixing plate. The fourth sliding groove is connected to the first sliding groove. The fourth sliding groove is used in conjunction with the stirring rod. The stirring rod passes through the fourth sliding groove and extends to the bottom of the fixing plate.

[0008] Preferably, the transmission mechanism includes a first gear, which is sleeved on the outside of the stirring rod and fixedly connected to the stirring rod. A rack is fixedly connected to the inner side of the second slide groove and meshes with the first gear. A servo motor is fixedly connected to the top of the treatment box. The output shaft of the servo motor vertically penetrates the treatment box and extends into the interior of the treatment box. The output shaft of the servo motor is rotatably connected to the treatment box. A second gear is fixedly connected to the output end of the servo motor. An external gear ring is fixedly connected to the inner side of the rotating plate and meshes with the second gear.

[0009] Preferably, a control panel is fixedly connected to the outside of the treatment box, and the servo motor is electrically connected to the control panel.

[0010] Preferably, the oxygenation mechanism includes a second slider, which is fixedly connected to a movable block. A third groove is provided inside the movable block on the side away from the second slider. The third groove cooperates with the second slider. A sleeve is provided inside the third groove. The sleeve is fixedly connected to the movable block. A piston is slidably connected inside the sleeve. A telescopic rod is fixedly connected to the outside of the piston near the second slider. The telescopic rod penetrates the sleeve vertically and extends to the outside of the sleeve. The telescopic rod is slidably connected to the sleeve. The second slider is fixedly connected to the telescopic rod.

[0011] Preferably, a first one-way valve is fixedly connected to the top of the sleeve near the telescopic rod, and a second one-way valve is fixedly connected to the top of the sleeve away from the telescopic rod. Both the first and second one-way valves are connected to the sleeve. A rotary joint is fixedly connected to the top of the stirring rod, and a flexible hose is fixedly connected between the rotary joint and the first one-way valve. The stirring rod has a hollow structure, and the rotary joint is connected to the stirring rod.

[0012] Preferably, a water inlet pipe is fixedly connected to the top of the treatment box, and a water outlet pipe is fixedly connected to one side of the treatment box. Both the water inlet pipe and the water outlet pipe are connected to the treatment box.

[0013] Preferably, a limiting plate is sleeved on the outside of the rotating plate, the limiting plate is fixedly connected to the rotating plate, and a limiting groove is opened inside the treatment box. The limiting groove is used in conjunction with the limiting plate, and both the limiting plate and the limiting groove are annular structures.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1) When using this landfill wastewater treatment device with oxygenation function, the servo motor is started. The servo motor drives the rotating plate to rotate back and forth through the second gear and the external gear ring. The rotating plate will squeeze the slide rod through the second slide groove, causing the slide rod to drive the movable block to move back and forth. The movable block directly drives the stirring rod to move back and forth in the treatment box. Moreover, during the process, under the action of the first gear and the rack, the stirring rod will also rotate back and forth in both directions, making the rotation mode of the stirring rod more diverse and more conducive to the agitation of wastewater and wastewater treatment agents, so that the two can be better mixed together.

[0015] 2) When this landfill wastewater treatment device with oxygenation function is in use, the moving block moves back and forth, which drives the telescopic rod to move back and forth through the second slider. The telescopic rod then drives the piston to move back and forth inside the sleeve. During this process, air enters the sleeve through the second one-way valve and enters the hose through the first one-way valve. Then the air enters the stirring rod with a hollow structure and is sprayed out, achieving the purpose of oxygenation. Moreover, the air entering the wastewater generates bubbles, which can realize gas stirring, thereby improving the stirring efficiency and making the wastewater and wastewater treatment agents mix more evenly.

[0016] 3) When this landfill wastewater treatment device with oxygenation function is in use, a limit plate is set on the outside of the rotating plate, and a limit groove is opened inside the treatment box to cooperate with the limit plate. Both the limit plate and the limit groove are annular structures. Since the rotating plate needs to rotate back and forth in the treatment box, in order to ensure the stability of the rotating plate during rotation, the rotating plate is limited by the limit groove and the limit plate. The rotating plate rotates back and forth, which will drive the limit plate to slide back and forth in the limit groove. Attached Figure Description

[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 see Figures 1 to 8A wastewater treatment device for landfills with oxygenation function includes a treatment box 1. A fixed plate 2 is fixedly connected inside the treatment box 1. A first groove 3 is formed on the upper surface of the fixed plate 2. A first slider 4 is slidably connected inside the first groove 3. A movable block 5 is fixedly connected to the top of the first slider 4. A rotating plate 6 is rotatably connected inside the treatment box 1 and above the movable block 5. A second groove 7 is formed inside the rotating plate 6. A sliding rod 8 is slidably connected inside the second groove 7. The sliding rod 8 vertically passes through the movable block 5 and extends to the bottom of the movable block 5. The sliding rod 8 is fixedly connected to the movable block 5. A stirring rod 9 is rotatably connected inside the sliding rod 8. The stirring rod 9 stirs the wastewater and wastewater treatment agents, so that the two can be mixed better and faster. A transmission mechanism 10 is set above the stirring rod 9. An oxygenation mechanism 11 is set inside the movable block 5. The oxygenation mechanism 11 can fill the wastewater with air to achieve the purpose of oxygenation.

[0021] Furthermore, the first slide 3 has a regular hexagonal structure, and there are six first sliders 4 in total. The six first sliders 4 are symmetrically distributed and point-symmetric about the center of the fixed plate 2. Correspondingly, the six movable blocks 5 fit together.

[0022] Furthermore, a fourth sliding groove 26 is provided on the lower surface of the fixing plate 2. The fourth sliding groove 26 is connected to the first sliding groove 3. The fourth sliding groove 26 is used in conjunction with the stirring rod 9. The stirring rod 9 passes through the fourth sliding groove 26 and extends to the bottom of the fixing plate 2. The fourth sliding groove 26 is provided to ensure the normal movement of the stirring rod 9 and prevent the stirring rod 9 from getting stuck.

[0023] Furthermore, the transmission mechanism 10 includes a first gear 12, which is sleeved on the outside of the stirring rod 9 and fixedly connected to the stirring rod 9. A rack 13 is fixedly connected to the inner side of the second slide groove 7, and the rack 13 meshes with the first gear 12. A servo motor 14 is fixedly connected to the top of the treatment box 1. The output shaft of the servo motor 14 vertically penetrates the treatment box 1 and extends into the interior of the treatment box 1. The output shaft of the servo motor 14 is rotatably connected to the treatment box 1. A second gear 15 is fixedly connected to the output end of the servo motor 14. An external gear is fixedly connected to the inner side of the rotating plate 6. The outer gear ring 16 meshes with the second gear 15. The servo motor 14 directly drives the second gear 15 to rotate, which in turn drives the rotating plate 6 to rotate back and forth in the treatment box 1. When the rotating plate 6 rotates, it will squeeze the slide rod 8 through the second slide groove 7, thereby driving the six movable blocks 5 to move simultaneously, so that the six movable blocks 5 can expand and contract. When the slide rod 8 slides in the second slide groove 7, it will drive the stirring rod 9 to rotate under the action of the first gear 12 and the rack 13. Moreover, the rotation direction of the stirring rod 9 is matched with the movement direction of the slide rod 8, and it has two rotation states: forward and reverse.

[0024] Furthermore, the control box 1 is externally fixedly connected to a control panel 29. The servo motor 14 is electrically connected to the control panel 29 and is powered by an external power supply. The control panel 29 controls the start, stop, forward and reverse rotation of the servo motor 14.

[0025] Furthermore, the oxygenation mechanism 11 includes a second slider 17, which is fixedly connected to the movable block 5. A third groove 18 is provided on the side of the movable block 5 away from the second slider 17. The third groove 18 is used in conjunction with the second slider 17. A sleeve 19 is provided inside the third groove 18, which is fixedly connected to the movable block 5. A piston 20 is slidably connected inside the sleeve 19. A telescopic rod 21 is fixedly connected to the outside of the piston 20 near the second slider 17. The telescopic rod 21 penetrates the sleeve 19 vertically and extends to the outside of the sleeve 19. The telescopic rod 21 is slidably connected to the sleeve 19. The second slider 17 is fixedly connected to the telescopic rod 21. When the rotating plate 6 rotates, it pushes the slide rod 8 through the second groove 7, causing the slide rod 8 to move the movable block 5. Since the six movable blocks 5 are in contact with each other, the second slider 17 on one side of the movable block 5 will move in the third groove 18 on the other side of the movable block 5.

[0026] Furthermore, a first one-way valve 22 is fixedly connected to the top of the sleeve 19 near the telescopic rod 21, and a second one-way valve 23 is fixedly connected to the top of the sleeve 19 away from the telescopic rod 21. Both the first one-way valve 22 and the second one-way valve 23 are connected to the sleeve 19. A rotary joint 24 is fixedly connected to the top of the stirring rod 9, and a hose 25 is fixedly connected between the rotary joint 24 and the first one-way valve 22. The stirring rod 9 has a hollow structure, and the rotary joint 24 is connected to the stirring rod 9. When the second slider 17 moves back and forth in the third slide groove 18... The piston 20 moves back and forth in the sleeve 19 via the telescopic rod 21. During this process, air enters the sleeve 19 through the second one-way valve 23, and then enters the hose 25 through the first one-way valve 22. It then enters the hollow stirring rod 9 and is finally discharged, thus achieving the purpose of oxygenating the sewage in the treatment tank 1. The discharged air forms bubbles in the sewage, which can achieve the purpose of gas stirring of sewage and improve the stirring efficiency to a certain extent, so that the sewage and sewage treatment agent can be mixed more evenly.

[0027] Furthermore, an inlet pipe 27 is fixedly connected to the top of the treatment box 1, and an outlet pipe 28 is fixedly connected to one side of the treatment box 1. Both the inlet pipe 27 and the outlet pipe 28 are connected to the treatment box 1. The inlet pipe 27 is used for adding sewage and sewage treatment agents, while the outlet pipe 28 is used for discharging the treated sewage.

[0028] Furthermore, a limiting plate 30 is fitted around the outside of the rotating plate 6, and the limiting plate 30 is fixedly connected to the rotating plate 6. A limiting groove 31 is opened inside the treatment box 1, and the limiting groove 31 is used in conjunction with the limiting plate 30. Both the limiting plate 30 and the limiting groove 31 are annular structures. Since the rotating plate 6 needs to rotate back and forth inside the treatment box 1, in order to ensure the stability of the rotating plate 6 when rotating, the limiting groove 31 and the limiting plate 30 limit the rotating plate 6. When the rotating plate 6 rotates back and forth, it will drive the limiting plate 30 to slide back and forth in the limiting groove 31.

[0029] The usage steps of this invention are as follows: When using this landfill wastewater treatment device with oxygenation function, wastewater and wastewater treatment agents are sequentially injected into the treatment tank 1 through the inlet pipe 27 at the top of the treatment tank 1. Then, the servo motor 14 is started via the control panel 29. The servo motor 14 drives the rotating plate 6 to rotate back and forth through the second gear 15 and the external gear ring 16. During this process, the rotating plate 6 presses against the sliding rod 8 through the second sliding groove 7, causing the sliding rod 8 to drive the movable block 5 to move back and forth. The movable block 5 directly drives the stirring rod 9 to move back and forth within the treatment tank 1. Furthermore, under the action of the first gear 12 and the rack 13, the stirring rod 9 also rotates back and forth in both directions, thus increasing the rotation speed of the stirring rod 9. The movement mode is more diverse and more conducive to the agitation of sewage and sewage treatment agents, so that the two can be better mixed together. When the movable block 5 moves back and forth, it will drive the telescopic rod 21 to move back and forth through the second slider 17. The telescopic rod 21 will drive the piston 20 to move back and forth in the sleeve 19. During the process, air will enter the sleeve 19 through the second one-way valve 23 and enter the hose 25 through the first one-way valve 22. Then the air will enter the stirring rod 9 with a hollow structure and finally be sprayed out from the stirring rod 9 to achieve the purpose of oxygenation. Moreover, the air entering the sewage will generate bubbles, which can realize gas agitation, thereby improving the agitation efficiency and making the sewage and sewage treatment agents mix more evenly.
