Description

Technical Field

[0001] The present invention relates to the technical field of landfill sewage treatment, and more specifically, to a landfill sewage treatment device with an oxygenation function. Background Art

[0002] Landfills generally use the method of layered soil covering for landfilling garbage. After piling up a layer of garbage, a layer of loess is covered, which can easily reduce the pollution of the garbage. There are two ways of garbage burial: dumping, digging an open pit on the ground and burying the garbage in the pit, with various animals (rats and birds) gathering around the pit. (This is the concept of landfills for most people.) Landfilling, building carefully designed facilities underground or on the ground to isolate the garbage from the surrounding environment (groundwater, air, and rainwater). This isolation is achieved through a bottom liner and daily soil covering. Sanitary landfill, isolating the garbage from the environment with a clay liner. Municipal solid waste landfill, isolating the garbage from the environment with a synthetic (plastic) liner. The purpose of landfilling is to bury the garbage so that it is separated from groundwater, kept dry, and not in contact with air. Under such conditions, the garbage will not decompose significantly. Landfills are different from compost piles, the latter aims to rapidly decompose the buried garbage.

[0003] In landfills, a relatively large amount of sewage is often generated. Usually, a sewage treatment device is needed to treat the sewage. Most of the methods are to introduce the sewage into the treatment tank in the device, then pour in the sewage treatment agent, and then mix the sewage and the sewage treatment agent by stirring. However, the stirring structures of some traditional sewage treatment devices are relatively simple, only driving the stirring rod to rotate in one direction by a motor, resulting in uneven mixing between the sewage and the sewage treatment agent, and they are also single in function and do not have an oxygenation function. Therefore, we provide a landfill sewage treatment device with an oxygenation function. Summary of the Invention

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

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

[0010] Preferably, the oxygenation mechanism includes a second slider fixedly connected to the movable block. On one side of the movable block away from the second slider, a third chute is provided. The third chute is used in cooperation with the second slider. Inside the third chute, a sleeve is provided. The sleeve is fixedly connected to the movable block. Inside the sleeve, a piston is slidably connected. On the outside of the piston near the second slider, a telescopic rod is fixedly connected. The telescopic rod vertically penetrates the sleeve and extends outside 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 one side of the top of the sleeve close to the telescopic rod, and a second one-way valve is fixedly connected to the other side of the top of the sleeve far from the telescopic rod. Both the first one-way valve and the second one-way valve are communicated with the sleeve. A rotary joint is fixedly connected to the top of the stirring rod, and a hose is fixedly connected between the rotary joint and the first one-way valve.

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

[0013] Preferably, a limiting plate is sleeved outside the rotating plate, and the limiting plate is fixedly connected to the rotating plate. A limiting groove is formed inside the treatment tank, and the limiting groove is used in cooperation with the limiting plate. Both the limiting plate and the limiting groove are of an annular structure.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1) When the garbage landfill sewage treatment device with an oxygenation function is in use, 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 sliding rod through the second chute, so that the sliding rod drives the movable block to move back and forth. The movable block directly drives the stirring rod to move back and forth in the treatment tank. Moreover, during the process, under the action of the first gear and the rack, the stirring rod will also rotate back and forth in the positive and negative directions, making the rotation mode of the stirring rod more diverse and more conducive to stirring the sewage and the sewage treatment agent, so that the two can be better mixed together.

[0015] 2) When the garbage landfill sewage treatment device with an oxygenation function is in use, when the movable block moves back and forth, it will drive the telescopic rod to move back and forth through the second slider, and the telescopic rod drives the piston to move back and forth in the sleeve. During the process, air will enter the sleeve through the second one-way valve and enter the hose through the first one-way valve, and then the air enters the stirring rod with a hollow structure and is ejected, achieving the purpose of oxygenation. Moreover, the air entering the sewage generates bubbles, which can realize gas stirring, thereby improving the stirring efficiency and making the sewage and the sewage treatment agent mix more evenly.

[0016] 3) When the garbage landfill sewage treatment device with an oxygenation function is in use, a limiting plate is arranged outside the rotating plate, and a limiting groove matching the limiting plate is formed inside the treatment tank. Both the limiting plate and the limiting groove are of an annular structure. Since the rotating plate needs to rotate back and forth in the treatment tank, in order to ensure the stability of the rotating plate during rotation, the rotating plate is limited by the limiting groove and the limiting plate, and the rotating plate rotates back and forth, driving the limiting plate to slide back and forth in the limiting groove.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 8, a sewage treatment device for landfills with an oxygenation function, including a treatment tank 1. Inside the treatment tank 1, there is a fixed connection with a fixed plate 2. On the upper surface of the fixed plate 2, there is a first chute 3. Inside the first chute 3, there is a sliding connection with a first slider 4. At the top of the first slider 4, there is a fixed connection with a movable block 5. Inside the treatment tank 1 and above the movable block 5, there is a rotatable connection with a rotating plate 6. Inside the rotating plate 6, there is a second chute 7. Inside the second chute 7, there is a sliding connection with a sliding rod 8. The sliding rod 8 vertically penetrates through the movable block 5 and extends below the movable block 5. The sliding rod 8 is fixedly connected to the movable block 5. Inside the sliding rod 8, there is a rotatable connection with a stirring rod 9. The sewage and sewage treatment agents are stirred by the stirring rod 9, so that the two can be better and faster mixed evenly. Above the stirring rod 9, there is a transmission mechanism 10. Inside the movable block 5, there is an oxygenation mechanism 11. The oxygenation mechanism 11 can fill air into the sewage to achieve the purpose of oxygenation.

[0021] Further, the first chute 3 is a regular hexagon structure. There are a total of six first sliders 4. The six first sliders 4 are symmetrically distributed. The six first sliders 4 are point-symmetrically distributed about the center of the fixed plate 2. Correspondingly, the six movable blocks 5 are in contact with each other.

[0022] Further, on the lower surface of the fixed plate 2, there is a fourth chute 26. The fourth chute 26 is communicated with the first chute 3. The fourth chute 26 is used in cooperation with the stirring rod 9. The stirring rod 9 passes through the fourth chute 26 and extends below the fixed plate 2. The opening of the fourth chute 26 is used to ensure the normal movement of the stirring rod 9 and prevent the stirring rod 9 from getting stuck.

[0023] Further, the transmission mechanism 10 includes a first gear 12. The first gear 12 is sleeved outside the stirring rod 9. The first gear 12 is fixedly connected to the stirring rod 9. Inside the second chute 7, there is a fixed connection with a rack 13. The rack 13 is meshed with the first gear 12. On the top of the treatment tank 1, there is a fixed connection with a servo motor 14. The output shaft of the servo motor 14 vertically penetrates through the treatment tank 1 and extends inside the treatment tank 1. The output shaft of the servo motor 14 is rotatably connected to the treatment tank 1. The output end of the servo motor 14 is fixedly connected to a second gear 15. Inside the rotating plate 6, there is a fixed connection with an external gear ring 16. The external gear ring 16 is meshed with the second gear 15. The servo motor 14 directly drives the second gear 15 to rotate, and in cooperation with the external gear ring 16, drives the rotating plate 6 to rotate back and forth inside the treatment tank 1. When the rotating plate 6 rotates, it will squeeze the sliding rod 8 through the second chute 7, thereby driving the six movable blocks 5 to move simultaneously, so that the six movable blocks 5 expand and contract. When the sliding rod 8 slides inside the second chute 7, it will drive the stirring rod 9 to rotate under the action of the first gear 12 and the rack 13, and the rotation direction of the stirring rod 9 is adapted to the moving direction of the sliding rod 8, having two rotation states of forward and reverse.

[0024] Further, a control panel 29 is fixedly connected to the outside of the treatment tank 1. The servo motor 14 is electrically connected to the control panel 29 and is powered by an external power supply. The start, stop, forward and reverse rotation of the servo motor 14 are controlled through the control panel 29.

[0025] Further, the oxygenation mechanism 11 includes a second slider 17. The second slider 17 is fixedly connected to the movable block 5. A third chute 18 is formed on the side of the interior of the movable block 5 away from the second slider 17. The third chute 18 is used in cooperation with the second slider 17. A sleeve 19 is arranged inside the third chute 18. The sleeve 19 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 side of the piston 20 close to the second slider 17. The telescopic rod 21 vertically penetrates through the sleeve 19 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 will push the sliding rod 8 through the second chute 7, so that the sliding rod 8 drives the movable block 5 to move. Since the six movable blocks 5 are in contact with each other, at this time, the second slider 17 on one side of the movable block 5 will move in the third chute 18 on the other side of the movable block 5.

[0026] Further, a first one-way valve 22 is fixedly connected to the side of the top of the sleeve 19 close to the telescopic rod 21, and a second one-way valve 23 is fixedly connected to the side of 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 communicated with the sleeve 19. A rotary joint 24 is fixedly connected to the top of the stirring rod 9. A hose 25 is fixedly connected between the rotary joint 24 and the first one-way valve 22. The stirring rod 9 is of a hollow structure. The rotary joint 24 is communicated with the stirring rod 9. When the second slider 17 moves back and forth in the third chute 18, it will drive the piston 20 to move back and forth in the sleeve 19 through the telescopic rod 21. During this process, air will enter the sleeve 19 through the second one-way valve 23, enter the hose 25 through the first one-way valve 22, then enter the hollow stirring rod 9, and finally be discharged, so as to achieve the purpose of oxygenating the sewage in the treatment tank 1. And the discharged air forms bubbles in the sewage. These bubbles can achieve the purpose of gas-stirring the sewage, and can also improve the stirring efficiency to a certain extent, so that the sewage and the sewage treatment agent can be mixed more evenly.

[0027] Further, a water inlet pipe 27 is fixedly connected to the top of the treatment tank 1, and a water outlet pipe 28 is fixedly connected to one side of the treatment tank 1. Both the water inlet pipe 27 and the water outlet pipe 28 are communicated with the treatment tank 1. The water inlet pipe 27 is used for discharging sewage and the sewage treatment agent, and the water outlet pipe 28 is used for discharging the treated sewage.

[0028] Further, a limiting plate 30 is sleeved outside the rotating plate 6. The limiting plate 30 is fixedly connected to the rotating plate 6. A limiting groove 31 is formed inside the treatment box 1. The limiting groove 31 is used in cooperation 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 during rotation, the rotating plate 6 is limited by the limiting groove 31 and the limiting plate 30. 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] Usage steps of the present invention: When the garbage landfill sewage treatment device with an oxygenation function is in use, sewage and sewage treatment agents are sequentially injected into the interior of the treatment box 1 through the water inlet pipe 27 at the top of the treatment box 1, and then the servo motor 14 is started through 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 will squeeze the sliding rod 8 through the second chute 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 inside the treatment box 1. Moreover, during this process, under the action of the first gear 12 and the rack 13, the stirring rod 9 will also rotate back and forth in the forward and reverse directions, making the rotation mode of the stirring rod 9 more diverse and more conducive to stirring the sewage and the sewage treatment agent, 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 drives the piston 20 to move back and forth in the sleeve 19. During this process, air will enter the sleeve 19 through the second one-way valve 23, enter the hose 25 through the first one-way valve 22, then enter the stirring rod 9 with a hollow structure, and finally be ejected from the stirring rod 9 to achieve the purpose of oxygenation. Moreover, the air entering the sewage generates bubbles, which can realize gas stirring, thereby improving the stirring efficiency and making the sewage and the sewage treatment agent mix more evenly.
