[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0035] In the above description of the present invention, it should be noted that the terms "one side" and "the other side" and the like indicate positions or locations based on the positions or locations shown in the accompanying drawings, or the positions or locations in which the product of the present invention is typically placed when in use.

Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0036] Furthermore, the term "identical" and similar terms do not necessarily require that the components be absolutely identical; slight variations are permitted. The term "perpendicular" simply refers to the positional relationship between components being more perpendicular than "parallel," not that the structure must be perfectly vertical; rather, it can be slightly tilted.

[0037] See also Figure 1-10 The utility model provides a technical solution: a livestock wastewater treatment device includes a treatment tank, a cover body, an air pump 1 and an odor exhaust gas adsorber 2. The treatment tank is used to accommodate livestock wastewater, and the livestock wastewater is treated in the treatment tank. The treatment tank can be a catalytic oxidation tank or a flocculation sedimentation tank used in the wastewater treatment process. The upper end of the treatment tank is open, and the cover body is arranged at the upper end of the treatment tank. The cover body covers the opening at the upper end of the treatment tank. The cover body is provided with an air inlet 3 for external air to enter its inner cavity. The air pump 1 can be a vortex air pump with model YX-71D, and the inlet end of the air pump 1 is connected to the inner cavity of the cover body through a pipeline. The odor exhaust gas adsorber 2 can be an activated carbon odor exhaust gas adsorber with model ZH-HB-FQ-20K, and the inlet end of the odor exhaust gas adsorber 2 is connected to the outlet end of the air pump 1 through a connecting pipe 4.

[0038] When using the livestock wastewater treatment device described in the present invention to treat wastewater, the wastewater is treated in the treatment tank. Specifically, in this embodiment, the treatment tank can be a flocculation sedimentation tank used in the wastewater treatment process, and impurities such as organic suspended matter in the wastewater are flocculated and precipitated in the flocculation sedimentation tank.

[0039] Because the cover is located at the upper end of the treatment tank and covers the opening at the upper end of the treatment tank, the cover can provide a certain barrier to the odorous gas components volatilized from the sewage, thereby reducing the odorous gas components that escape into the surrounding environment and reducing the impact on the surrounding environment. During the wastewater treatment process, the air pump 1 can also be started. Under the suction action of the air pump 1, the gas within the cover can sequentially pass through the pipeline, the air pump 1, and the connecting pipe 4 into the odorous waste gas adsorber 2. The odorous waste gas adsorber 2 can adsorb the odorous gas components in the gas entering it, further reducing the odorous gas components that escape into the surrounding environment and further reducing the impact on the surrounding environment. While the air pump 1 is sucking the gas within the cover, air outside the cover can enter the cover through the air inlet 3 to replenish the gas within the cover.

[0040] In this embodiment, the cover includes a first end plate, a second end plate, and an arc-shaped plate. The first and second end plates are fixedly mounted on the upper end surface of the treatment tank and are located on the front and rear sides of the opening, respectively. The top of the arc-shaped plate faces upward, the front end of the arc-shaped plate is fixedly connected to the first end plate, and the rear end is fixedly connected to the second end plate. The left and right ends of the arc-shaped plate are respectively located on the left and right sides of the opening, and the lower sides of the left and right ends of the arc-shaped plate abut against the upper side surface of the treatment tank. The air inlet 3 is located on the first end plate. With this structure, the cover can cover the opening at the upper end of the treatment tank.

[0041] In this embodiment, the front end of the arc plate is detachably fixedly connected to the first end plate, and the rear end is detachably fixedly connected to the second end plate. The arc plate is a structure that can be extended and retracted along the front-to-back direction.

[0042] When it is necessary to clean the solid impurities in the treatment pool, the front end of the arc plate can be removed from the first end plate, the rear end of the arc plate can be removed from the second end plate, and then the arc plate can be compressed in the front-to-back direction to reduce the obstruction of the opening at the upper end of the treatment pool by the arc plate, making it easier for workers to enter the treatment pool and also easier for workers to throw the solid impurities in the treatment pool out of the treatment pool.

[0043] In this embodiment, the arc plate includes multiple arc rods 5 and multiple connecting pieces 6. The arc tops of the arc rods 5 face upward, and the multiple arc rods 5 are arranged in sequence along the front-to-back direction. A connecting piece 6 is provided between each two adjacent arc rods 5. The front end of the connecting piece 6 is fixedly connected to one of the arc rods 5, and the rear end is fixedly connected to the other arc rod 5. The connecting piece 6 closes the gap between the two arc rods 5. The connecting piece 6 is made of a flexible and airtight material, and the connecting piece 6 can be a plastic film.

[0044] Since the connecting piece 6 is made of a flexible airtight material, the flexible piece is easily deformed, so that each two adjacent arc-shaped rods 5 can move toward each other and approach each other in the front-to-back direction, and also each two adjacent arc-shaped rods 5 can move away from each other and move away from each other in the front-to-back direction. With this structure, the arc plate can be a structure that can be extended and retracted along the front-to-back direction.

[0045] In this embodiment, the treatment pool includes a treatment pool body 7, multiple first sliders 8 and multiple second sliders 9. The upper end surface of the treatment pool body 7 is recessed downward to form a first slide groove and a second slide groove. The first slide groove and the second slide groove are both arranged along the front and rear directions. The first slide groove and the second slide groove are respectively located on the left and right sides of the opening. The first slider 8 slides in the first slide groove, and the second slider 9 slides in the second slide groove. The multiple first sliders 8 are fixed one by one to the left ends of the multiple arc rods 5, and the multiple second sliders 9 are fixed one by one to the right ends of the multiple arc rods 5.

[0046] The first chute can guide the first slider 8, allowing the first slider 8 to continue sliding in the front-to-back direction, and the second chute can guide the second slider 9, allowing the second slider 9 to continue sliding in the front-to-back direction. Because the left and right ends of the arc-shaped rod 5 are respectively fixedly connected to the corresponding first slider 8 and the corresponding second slider 9, the first and second chute can guide the movement of the arc-shaped rod 5 in the front-to-back direction, making it less likely for the arc-shaped rod 5 to deviate during its front-to-back movement.

[0047] In this embodiment, the opening size of the first chute is smaller than the cavity size of the first chute, and the opening size of the second chute is smaller than the cavity size of the second chute. Specifically, the cross-section of the first chute can be a dovetail shape with a smaller top and a larger bottom. With this structure, the opening size of the first chute can be smaller than the cavity size of the first chute. The cross-section of the second chute can also be a dovetail shape with a smaller top and a larger bottom. With this structure, the opening size of the second chute can be smaller than the cavity size of the second chute.

[0048] With this structure, the first slider 8 is not easily dislodged from the first chute, and the second slider 9 is not easily dislodged from the second chute, thereby increasing the structural stability of the livestock wastewater treatment device of the present invention.

[0049] In this embodiment, a plurality of first screws 10 are fixed on the arc rod 5 closest to the first end plate, and a first through hole is formed on the first end plate at a position corresponding to each of the first screws 10, and the first screw 10 passes forward through the corresponding first through hole and is screwed with a first nut 11; a plurality of second screws 12 are fixed on the arc rod 5 closest to the second end plate, and a second through hole is formed on the second end plate at a position corresponding to each of the second screws 12, and the second screw 12 passes backward through the corresponding second through hole and is screwed with a second nut 13.

[0050] Since the first screw rod 10 is screwed with the first nut 11 after passing through the corresponding first through hole, it is only necessary to rotate the first nut 11 on the first screw rod 10 so that the first nut 11 abuts and presses against the first end plate, and the arc rod 5 closest to the first end plate can be fixed to the first end plate, and the front end of the arc plate can be fixedly connected to the first end plate. By unscrewing the first nut 11 from the corresponding first screw rod 10, the arc rod 5 closest to the first end plate can be moved backward, and the first screw rod 10 can be pulled backward out of the first through hole. At this time, the arc rod 5 closest to the first end plate can be removed from the first end plate, and the front end of the arc plate can be removed from the first end plate. With this structure, the front end of the arc plate can be detachably fixed to the first end plate.

[0051] Since the second screw rod 12 is screwed with the second nut 13 after passing through the corresponding second through hole, it is only necessary to rotate the second nut 13 on the second screw rod 12 so that the second nut 13 abuts and presses against the second end plate, and the arc rod 5 closest to the second end plate can be fixed to the second end plate, and the rear end of the arc plate can be fixedly connected to the second end plate. By unscrewing the second nut 13 from the corresponding second screw rod 12, the arc rod 5 closest to the second end plate can be moved forward, and the second screw rod 12 can be pulled forward from the second through hole. At this time, the arc rod 5 closest to the second end plate can be removed from the second end plate, and the rear end of the arc plate can be removed from the second end plate. With this structure, the rear end of the arc plate can be detachably fixed to the second end plate.

[0052] In this embodiment, a channel 14 is provided in the arc-shaped rod 5, and the channel 14 is arranged along the length direction of the arc-shaped rod 5. The arc-shaped rod 5 is provided with a plurality of air inlet holes 15, and the plurality of air inlet holes 15 are arranged at intervals along the length direction of the arc-shaped rod 5. The air inlet holes 15 are used to allow the gas in the cover to enter the channel 14;

[0053] The pipeline includes a first tube 16 and multiple second tubes 17. In this embodiment, the first tube 16 and the second tube 17 are both rubber hoses, and the lengths of the first tube 16 and the second tube 17 can be arbitrarily set as needed. One end of the first tube 16 is closed, and the other end is connected to the air inlet of the air pump 1. One end of the multiple second tubes 17 is fixedly connected to the multiple curved rods 5 in a one-to-one correspondence. The inner lumens of the second tubes 17 are connected to the corresponding channels 14. The other ends of the multiple second tubes 17 are fixedly connected to the first tube 16, and the lumens of the second tubes 17 are connected to the lumens of the first tube 16.

[0054] When the air pump 1 is activated, the air within the housing enters the corresponding channel 14 through the inlet holes on each of the curved rods 5. The air then enters the plurality of first air pipes from each channel 14 in a one-to-one correspondence. The air then enters the second air pipe from the plurality of first air pipes, and then enters the odorous waste gas adsorber 2 in sequence through the second air pipes, the air pump 1, and the connecting pipe 4. With this structure, the air within the housing can be simultaneously sucked from multiple locations, improving the removal of odorous gas components within the housing.

[0055] In this embodiment, two sealing tapes 18 are also included, one of which is used to seal the gap between the left edge of the curved plate and the upper end surface of the treatment pool, and the other sealing tape 18 is used to seal the gap between the right edge of the curved plate and the upper end surface of the treatment pool.

[0056] One of the sealing tapes 18 is used to seal the gap between the left edge of the curved plate and the upper end surface of the treatment tank, and the other sealing tape 18 is used to seal the gap between the right edge of the curved plate and the upper end surface of the treatment tank. This prevents gas within the cover from escaping into the surrounding environment through the gaps between the left edge of the curved plate and the upper end surface of the treatment tank, as well as the gaps between the right edge of the curved plate and the upper end surface of the treatment tank, thereby further reducing the impact on the surrounding environment.

[0057] In this embodiment, the first end plate includes a first end plate body 19 and a first soft elastic rubber layer 20, and the first soft elastic rubber layer 20 is fixed on a side of the first end plate body 19 facing the second end plate; the second end plate includes a second end plate body 21 and a second soft elastic rubber layer 22, and the second soft elastic rubber layer 22 is fixed on a side of the second end plate body 21 facing the first end plate.

[0058] When the arc-shaped rod 5 closest to the first end plate is fixedly connected to the first end plate, the first soft elastic rubber layer 20 can seal the gap between the arc-shaped rod 5 closest to the first end plate and the first end plate body 19, thereby reducing the possibility of gas in the cover escaping from the gap between the arc-shaped rod 5 closest to the first end plate and the first end plate into the surrounding environment. When the arc-shaped rod 5 closest to the second end plate is fixedly connected to the second end plate, the second soft elastic rubber layer 22 can seal the gap between the arc-shaped rod 5 closest to the second end plate and the second end plate body 21, thereby reducing the possibility of gas in the cover escaping from the gap between the arc-shaped rod 5 closest to the second end plate and the second end plate into the surrounding environment. With this structure, the impact on the surrounding environment can be further reduced.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
