Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to a sewage treatment device for chicken farms. Background Art

[0002] Chicken manure sewage not only contains high-concentration organic pollutants and high-concentration solid suspended matters, but also is rich in nutrients such as nitrogen and phosphorus, and has a high ammonia nitrogen content. When treating chicken manure sewage, a dry-wet separator is used to separate chicken manure from sewage, and then a sewage treatment device is used to treat the sewage. Currently, when treating chicken manure sewage, a biological filtration method is generally used. The biological filtration method utilizes microorganisms to consume nutrients such as nitrogen and phosphorus. This treatment method has low maintenance costs and good treatment effects.

[0003] The above sewage treatment method has relatively high requirements for environmental temperature. In summer, the environmental temperature is high, which makes the activity of microorganisms good, enabling the above device to be used well. However, in winter, the environmental temperature is too low. Even though microorganisms will generate a certain temperature during anaerobic and aerobic treatments, the generated temperature cannot reach the optimal environmental temperature for microorganisms, thereby reducing the activity of microorganisms. This causes the treatment effect of the above device to deteriorate when treating sewage. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1.

Specific embodiments

[0027] 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.

[0028] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0029] Refer to Figures 1-8 , a sewage treatment device for a chicken farm, including a treatment tank 1, a primary aerobic treatment tank 2, a secondary aerobic treatment tank 3, an anaerobic treatment tank 4, a sedimentation tank 5 and a disinfection tank 6 are respectively arranged in the treatment tank 1, a water addition tank 7 is fixedly connected to the upper surface of the treatment tank 1, and a first telescopic pipe 8 is communicated with one side side wall of the water addition tank 7. One end of the first telescopic pipe 8 is communicated with a sliding box 9, a flexible hose 10 is communicated with one side side wall of the sliding box 9, and one end of the flexible hose 10 is communicated with the anaerobic treatment tank 4. A connecting pipe 11 is communicated with one side side wall of the secondary aerobic treatment tank 3, and one end of the connecting pipe 11 penetrates through the sliding box 9, the first telescopic pipe 8 and the water addition tank 7 and is communicated with the sedimentation tank 5. A driving mechanism is fixedly connected to the upper surface of the treatment tank 1, a sealing mechanism is slidably sleeved on the outer wall of the connecting pipe 11, and the sealing mechanism is fixedly connected to the sliding box 9;

[0030] As can be seen from the above structure: By setting the first telescopic pipe 8 to cooperate with the connecting pipe 11, etc., the sewage treated in the anaerobic treatment tank 4 is anaerobically treated. The water after anaerobic treatment is aerobically treated through the first aerobic treatment tank 2 and the second aerobic treatment tank 3. The sewage after aerobic treatment enters the sedimentation tank 5 through the connecting pipe 11 for sedimentation, and the sewage after sedimentation is discharged after being disinfected in the disinfection tank 6;

[0031] When the sewage passes through the connecting pipe 11, the sewage to be treated is simultaneously introduced into the water addition tank 7. The water entering the water addition tank 7 enters the sliding box 9 through the first telescopic pipe 8. The water entering the sliding box 9 enters the anaerobic treatment tank 4 through the hose 10 for treatment. When the sewage passes through the first telescopic pipe 8, the sewage will absorb the heat in the sewage after aerobic treatment completion through the connecting pipe 11, thereby increasing the heat of the sewage entering the anaerobic treatment tank 4, so as to increase the temperature of the sewage when the sewage is aerobically and anaerobically treated, ensure the temperature during aerobic and anaerobic treatment, and try to avoid affecting the effects of aerobic and anaerobic treatment due to too low temperature.

[0032] Furthermore, the driving mechanism includes a mounting plate 12 fixed to the treatment tank 1. A lead screw 13 is rotatably connected to the side wall of the mounting plate 12. A connecting block 14 is threadedly sleeved on the outer wall of the lead screw 13. One side wall of the connecting block 14 is fixedly connected to the sliding box 9. A motor 15 is fixedly connected to the upper surface of the treatment tank 1, and the driving end of the motor 15 is fixedly connected to the lead screw 13. A temperature sensor 16 is fixedly connected to one side wall of the treatment tank 1. A controller 17 is fixedly connected to the upper surface of the treatment tank 1, and the controller 17 is electrically connected to the temperature sensor 16, and the controller 17 is electrically connected to the motor 15; By setting the motor 15 and the lead screw 13 to cooperate with each other, when in use, if the temperature sensor 16 detects that the temperature in the second aerobic treatment tank 3 is lower or higher than a certain degree, the controller 17 starts the motor 15, so that the motor 15 drives the lead screw 13 to rotate. The rotating lead screw 13 drives the connecting block 14 to move, and the moving connecting block 14 drives the sliding box 9 to move, so that the sliding box 9 lengthens or shortens the first telescopic pipe 8, thereby increasing or decreasing the length of the heat exchange of the sewage in the connecting pipe 11 and the first telescopic pipe 8, and then changing the temperature of the sewage entering the anaerobic treatment tank 4, so that the temperature of the sewage remains constant at the temperature most suitable for microorganisms, and thus the treatment effect of the sewage can be further improved.

[0033] Further, the sealing mechanism includes a sliding sleeve 18 sleeved on the outer wall of the connecting pipe 11. An annular groove 19 is formed in the inner wall of the sliding sleeve 18. A rubber scraping ring 20 is fixedly connected to the inner wall of the annular groove 19. The rubber scraping ring 20 is slidably sleeved on the outer wall of the connecting pipe 11. An elastic membrane 21 is fixedly connected to the inner wall of the annular groove 19. One side wall of the elastic membrane 21 is fixedly connected to the rubber scraping ring 20. A fixing groove is formed in the upper surface of the sliding box 9, and a pressure control mechanism is fixedly connected to the inner wall of the fixing groove; by providing the sliding sleeve 18, the elastic membrane 21 and the pressure control mechanism, when the sliding box 9 does not move, the pressure control mechanism can control the elastic membrane 21 to tightly press against the outer wall of the connecting pipe 11, which can prevent the sliding box 9 from leaking water. When the sliding box 9 is moved, the pressure control mechanism can be released, thereby reducing the tightness of the contact between the elastic membrane 21 and the connecting pipe 11, and thus facilitating the movement of the sliding box 9.

[0034] Further, the pressure control mechanism includes a housing 22 fixedly connected to the inner wall of the fixing groove. A bellows 23 is fixedly connected to the inner wall of the housing 22. A conduit 24 is fixedly connected to one side wall of the housing 22, and one end of the conduit 24 communicates with the bellows 23. The other end of the conduit 24 communicates with the annular groove 19. One end of the bellows 23 is fixedly connected to a pressing plate 25, and a pressing rod 26 is fixedly connected to the upper surface of the pressing plate 25. One end of the pressing rod 26 penetrates through the housing 22 and extends to the outside of the housing 22. A fixing plate 27 is fixedly connected to the upper surface of the sliding box 9, and a rocker 28 is rotatably connected to one side wall of the fixing plate 27. The rocker 28 is arranged above the pressing rod 26, and a magnet 29 is fixedly connected to one end of the rocker 28. An electromagnet 30 is arranged below the magnet 29, and the electromagnet 30 is fixedly connected to the sliding box 9. The electromagnet 30 is electrically connected to the controller 17; before the motor 15 is started, the controller 17 first controls the electromagnet 30 to start. After starting, the electromagnet 30 repels the magnet 29, thereby causing the electromagnet 30 to push the magnet 29 and the rocker 28 to move. After the rocker 28 moves, the pressing plate 25 can move. At this time, the pressure in the annular groove 19 can enter the bellows 23 to complete pressure relief. At this time, the tightness of the contact between the elastic membrane 21 and the connecting pipe 11 can be reduced, and thus the movement of the sliding box 9 is facilitated;

[0035] After the sliding box 9 stops moving, the electromagnet 30 is powered off. At this time, the magnet 29 attracts the electromagnet 30, causing the rocker 28 to press down. The pressing rocker 28 presses the pressing rod 26, the pressing plate 25 and the bellows 23, thereby pressing the medium back into the annular groove 19 again, increasing the pressure in the annular groove 19. The increased pressure presses the elastic membrane 21 tightly against the outer wall of the connecting pipe 11, which can prevent the sliding box 9 from leaking water.

[0036] Further, a spring 31 is arranged in the bellows 23, and one end of the spring 31 is fixedly connected to the pressing plate 25; by providing the spring 31, after the rocker 28 moves, the spring 31 can push the pressing plate 25 to move, thereby causing the bellows 23 to expand.

[0037] Further, a card slot is formed on the lower surface of the sliding box 9, and a roller rod 32 is arranged in the card slot. One side wall of the roller rod 32 contacts the treatment box 1. By arranging the roller rod 32, the friction between the sliding box 9 and the treatment box 1 can be reduced.

[0038] Further, a sliding rod 33 is fixedly connected to one side wall of the erection plate 12, and one end of the sliding rod 33 penetrates through the connecting block 14. By arranging the sliding rod 33, the connecting block 14 can be limited to ensure the stability of the movement of the connecting block 14.

[0039] Further, a second telescopic tube 34 is sleeved on the outer wall of the connecting pipe 11. One end of the second telescopic tube 34 is fixedly connected to the connecting pipe 11, and one end of the second telescopic tube 34 is fixedly connected to the sliding sleeve 18. By arranging the second telescopic tube 34, a section of the connecting pipe 11 can be protected.

[0040] In the present invention, when in use, the sewage treated in the anaerobic treatment tank 4 is anaerobically treated. The water after anaerobic treatment is aerobically treated through the primary aerobic treatment tank 2 and the secondary aerobic treatment tank 3. The sewage after aerobic treatment enters the sedimentation tank 5 through the connecting pipe 11 for sedimentation. The sewage after sedimentation is discharged after being disinfected by the disinfection tank 6;

[0041] When the sewage passes through the connecting pipe 11, the sewage to be treated is simultaneously introduced into the water addition tank 7. The water entering the water addition tank 7 enters the sliding box 9 through the first telescopic tube 8. The water entering the sliding box 9 enters the anaerobic treatment tank 4 through the hose 10 for treatment. When the sewage passes through the first telescopic tube 8, the sewage will absorb the heat in the sewage after the aerobic treatment is completed through the connecting pipe 11, thereby increasing the heat of the sewage entering the anaerobic treatment tank 4, so as to increase the temperature of the sewage when the sewage is aerobically and anaerobically treated, ensure the temperature during aerobic and anaerobic treatment, and try to avoid affecting the effects of aerobic and anaerobic treatment due to too low temperature;

[0042] When in use, if the temperature sensor 16 detects that the temperature in the secondary aerobic treatment tank 3 is lower than or higher than a certain degree, the controller 17 starts the motor 15, so that the motor 15 drives the lead screw 13 to rotate. The rotating lead screw 13 drives the connecting block 14 to move. The moving connecting block 14 drives the sliding box 9 to move, so that the sliding box 9 lengthens or shortens the first telescopic tube 8, thereby increasing or decreasing the length of the heat exchange of the sewage in the connecting pipe 11 and the first telescopic tube 8, and then changing the temperature of the sewage entering the anaerobic treatment tank 4, so that the temperature of the sewage remains constant at the temperature most suitable for microorganisms, and further improving the treatment effect of the sewage;

[0043] Before the motor 15 starts, the controller 17 first controls the electromagnet 30 to start. After starting, the electromagnet 30 repels the magnet 29, so that the electromagnet 30 pushes the magnet 29 and the rocker 28 to move. After the rocker 28 moves, the spring 31 can push the pressure plate 25 to move, so that the corrugated pipe 23 unfolds. At this time, the pressure in the annular groove 19 can enter the corrugated pipe 23 to complete pressure relief. At this time, the tightness of the contact between the elastic membrane 21 and the connecting pipe 11 can be reduced, so as to facilitate the movement of the sliding box 9;

[0044] After the sliding box 9 stops moving, the electromagnet 30 is powered off. At this time, the magnet 29 attracts the electromagnet 30, so that the rocker 28 presses down. The pressed-down rocker 28 presses the pressure rod 26, the pressure plate 25 and the corrugated pipe 23, so as to press the medium back into the annular groove 19 again, so that the pressure in the annular groove 19 increases. The increased pressure presses the elastic membrane 21 tightly against the outer wall of the connecting pipe 11, which can prevent the sliding box 9 from leaking water.

[0045] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
