Description

Technical Field

[0001] This invention relates to the technical field of wastewater treatment, and in particular to a wastewater treatment device for livestock slaughtering. Background Technology

[0002] Livestock slaughter wastewater contains a large amount of grease, suspended solids, and colloidal substances. Air flotation is one of the important pretreatment processes for treating this type of wastewater. Traditional air flotation equipment usually uses aeration pipes or microporous diffusers laid at the bottom or side of the air flotation tank to directly introduce gas into the tank. The gas is precipitated or diffused in the wastewater to form microbubbles, and the pollutants are adsorbed and carried to the surface by the bubbles to achieve separation. In this type of device, the wastewater generally flows horizontally through the air flotation area. The water flow path and the rising trajectory of the bubbles have limited intersection, resulting in short contact time between the bubbles and pollutants and a low probability of collision. At the same time, in order to ensure the coverage area of ​​air flotation, a large number of pipes and dense air holes need to be laid at the bottom of the tank. The system structure is complex, the uniformity of air distribution is difficult to control, the energy consumption is high, and it is prone to clogging and difficult to maintain. More importantly, since the wastewater passes through the air flotation zone in one direction only, the unremoved pollutants cannot come into contact with the bubbles again. The single-stage treatment efficiency is limited, especially the removal effect of emulsified grease and fine suspended solids is not good, making it difficult to meet the increasingly strict discharge or reuse standards. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a livestock slaughter wastewater treatment device, the specific technical solution of which is as follows: The present invention provides a livestock slaughter wastewater treatment device, comprising a horizontally arranged wastewater tank, an inlet pipe and an overflow pipe connected at both ends of the wastewater tank, and a sludge discharge hopper at the top of the wastewater tank; Two fillers are arranged opposite each other inside the sewage tank. The length direction of the fillers is parallel to the axis of the sewage tank. Both fillers form a return channel with the inner wall of the sewage tank. The two fillers form a vertical treatment channel. Several push plates for pushing the wastewater upward are provided in the return channel. An exhaust structure for discharging air bubbles into the wastewater is provided in the treatment channel.

[0004] Furthermore, the sewage tank includes a cylinder body located in the middle and two end plates located on both sides of the cylinder body. Each end plate consists of a core plate located in the middle, a rotating ring II located on the outer circumference of the core plate, and a fixed ring located on the outer circumference of the rotating ring II. The fixed ring is connected to the cylinder body through a rotating ring I. The cylinder body, the fixed ring, and the core plate are relatively fixed by several fixing frames. Both the rotating ring I and the rotating ring II can be rotatably set. The inlet pipe and the overflow pipe are respectively installed on the two core discs, and the sewage hopper and the filling body are installed on the cylinder; The two return channels form a circular channel. The portion of the pusher plate near the inner wall of the sewage cylinder is rotatably connected to the first rotating ring, and the portion of the pusher plate near the outer wall of the filling body is rotatably connected to the second rotating ring. In one return channel, the pusher plate on the first rotating ring is upright, and the pusher plate on the second rotating ring is tilted. In the other return channel, the pusher plate on the first rotating ring is tilted, and the pusher plate on the second rotating ring is upright.

[0005] Furthermore, two annular grooves are provided on the side wall of the fixed ring, which are distributed in an inner and outer manner. The annular grooves include an arc groove one, an arc groove two, and two transition grooves. The transition grooves are used to connect the arc groove one and the arc groove two. A plurality of sliding pillars are provided in the annular grooves, and the sliding pillars are connected to the corresponding push plates. The push plate is connected to the corresponding rotating ring one or rotating ring two via an elastic body one.

[0006] Furthermore, the exhaust structure includes an air guide chamber formed in each of the filling bodies and a plurality of air diffuser pipes connecting the two filling bodies. The air diffuser pipes are connected to the air guide chambers, and a plurality of air diffuser holes are formed on the side wall of the air diffuser pipes.

[0007] Furthermore, an air guide groove is provided on the lower side inside the air diffuser, and a sealing body is vertically slidably disposed inside the air diffuser. The side wall of the sealing body is used to block the air diffuser hole, and the top of the sealing body slides out of the air diffuser.

[0008] Furthermore, the lower side of the vent is densely covered with several protrusions.

[0009] Furthermore, the overflow pipe is rotatably mounted on the corresponding core disk via an adjusting sleeve. Several slots are provided on the outer wall of the adjusting sleeve and on the core disk for mutual cooperation. A movable sleeve is slidably mounted on the overflow pipe. The movable sleeve and the overflow pipe are connected by an elastic body. Several locking ridges are provided on the outer wall of the movable sleeve. The locking ridges are slidably engaged with the slots on the adjusting sleeve and the slots on the core disk.

[0010] Furthermore, the processing device also includes a power unit, which includes a drive motor fixed relative to the core disk. The output end of the drive motor is provided with a transmission wheel one. One side of the transmission wheel one is connected to the corresponding rotating ring two. The other side of the transmission wheel one is provided with a transmission wheel two. The transmission wheel two and the corresponding rotating ring one are connected by a transmission wheel three.

[0011] The beneficial effects of this invention are as follows: By circulating the wastewater through the area between the two packing bodies, the wastewater can come into contact with the air bubbles discharged from the exhaust structure multiple times, achieving circulating flotation treatment of the wastewater and effectively improving the removal of impurities. At the same time, since the wastewater and the air bubbles move in opposite directions, the impact of the wastewater on the air bubbles can reduce the rising speed of the air bubbles, thereby extending the residence time of the air bubbles in the wastewater. Furthermore, the impact of the wastewater on the air bubbles can prevent the formation of large air bubbles. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figures 1 to 9 As shown, a livestock slaughter wastewater treatment device of the present invention includes a horizontally arranged sewage tank 1, an inlet pipe 2 and an overflow pipe 3 connected at both ends of the sewage tank 1, and a sewage discharge hopper 4 arranged at the top of the sewage tank 1. Two fillers 5 are arranged opposite each other inside the sewage tank 1. The length direction of the fillers 5 is parallel to the axis of the sewage tank 1. Both fillers 5 form a return channel 6 with the inner wall of the sewage tank 1. The two fillers 5 form a vertical treatment channel 7. Several push plates 8 are provided in the return channel 6 to push the wastewater upward. An exhaust structure is provided in the treatment channel 7 to discharge air bubbles into the wastewater.

[0019] In this invention, the sewage tank 1 is fixed, and the inlet pipe 2 can introduce wastewater into the sewage tank 1 from one end. The wastewater in the sewage tank 1 can be discharged through the overflow pipe 3 at the other end, and the overflow pipe 3 can ensure that the wastewater level in the sewage tank 1 is always at a specified position. The sewage discharge hopper 4 is connected to the top of the sewage tank 1 and is used to collect air flotation impurities. Since the wastewater in the sewage tank 1 flows horizontally, the sewage discharge hopper 4 can be set as follows: Figure 1 As shown in the structure, the top of the sewage hopper 4 is inclined towards the overflow pipe 3, and the output end of the sewage hopper 4 is close to the overflow pipe 3 in the horizontal direction. In this way, the flow of wastewater in the sewage tank 1 can be used to make the air flotation impurities accumulate in the sewage hopper 4 and be naturally discharged through the output end of the sewage hopper 4.

[0020] Two packing bodies 5 are distributed one in front of the other inside the sewage tank 1, and the two ends of the packing bodies 5 are connected to the left and right ends of the sewage tank 1 respectively. The return channel 6 formed between the outer wall of the packing bodies 5 and the inner wall of the sewage tank 1 allows wastewater to flow upward, and the treatment channel 7 formed between the two packing bodies 5 allows wastewater to flow downward. Thus, the wastewater circulates between the return channel 6 and the treatment channel 7, and the wastewater can continuously flow downward in the treatment channel 7. This facilitates the wastewater to repeatedly pass through the exhaust structure, and the direction of the wastewater flow is opposite to the upward floating direction of the bubbles discharged by the exhaust structure.

[0021] In use, wastewater is continuously introduced into the sewage tank 1 through the inlet pipe 2. Several push plates 8 in the return channel 6 move and push the wastewater in the return channel 6 upward along the inner wall of the sewage tank 1, so that the wastewater in the two return channels 6 gathers at the top of the treatment channel 7 and flows downward. The wastewater flows to the bottom of the treatment channel 7 and disperses into the two return channels 6, thus forming a circulating flow of wastewater on a vertical plane perpendicular to the axis of the sewage tank 1. The overall flow direction of the wastewater in the sewage tank 1 is horizontal. The air bubbles discharged into the treatment channel 7 by the exhaust structure float up and adsorb impurities in the wastewater flowing downward in the treatment channel 7. The air bubbles carry the impurities upward to the sewage discharge hopper 4. As the impurities continue to increase, the impurities accumulate and are discharged through the output end of the sewage discharge hopper 4. The wastewater circulates through the treatment channel 7, so that the wastewater can come into contact with the air bubbles multiple times. When the wastewater that has completed the air flotation flows to the overflow pipe 3, the wastewater can be discharged naturally through the overflow pipe 3, thus realizing the continuous air flotation treatment of wastewater.

[0022] By circulating the wastewater through the area between the two fillers 5, the wastewater can come into contact with the air bubbles discharged from the exhaust structure multiple times, achieving circulating flotation treatment of the wastewater and effectively improving the removal of impurities. At the same time, since the wastewater and the air bubbles move in opposite directions, the impact of the wastewater on the air bubbles can reduce the rising speed of the air bubbles, thereby extending the residence time of the air bubbles in the wastewater. Furthermore, the impact of the wastewater on the air bubbles can prevent the formation of large air bubbles.

[0023] Furthermore, the sewage cylinder 1 includes a cylinder 9 located in the middle and two end plates 10 located on both sides of the cylinder 9. The end plate 10 is composed of a core plate 12 located in the middle, a rotating ring 13 located on the outer circumference of the core plate 12, and a fixed ring 14 located on the outer circumference of the rotating ring 13. The fixed ring 14 is connected to the cylinder 9 through a rotating ring 11. The cylinder 9, the fixed ring 14, and the core plate 12 are relatively fixed by several fixing frames 15. The rotating ring 11 and the rotating ring 13 can be rotatably set. The inlet pipe 2 and the overflow pipe 3 are respectively installed on the two core discs 12, and the sewage hopper 4 and the filling body 5 are installed on the cylinder 9; Two return channels 6 form a circular channel. The portion of several push plates 8 near the inner wall of the sewage cylinder 1 is rotatably connected to the rotating ring 11. The portion of several push plates 8 near the outer wall of the filling body 5 is rotatably connected to the rotating ring 2 13. In one return channel 6, the push plate 8 on the rotating ring 11 is upright, and the push plate 8 on the rotating ring 2 13 is tilted. In the other return channel 6, the push plate 8 on the rotating ring 11 is tilted, and the push plate 8 on the rotating ring 2 13 is upright.

[0024] Rotating ring 11 rotates between cylinder 9 and fixed ring 14, while rotating ring 2 13 rotates between core disk 12 and fixed ring 14. The rotation directions of rotating ring 11 and rotating ring 2 13 are opposite, allowing them to drive several push plates 8 on each ring to rotate synchronously in opposite directions. When the push plates 8 on rotating ring 11 move into a return channel 6, the push plates 8 rotate on rotating ring 11 and unfold vertically. At this time, the push plates 8 have a large contact surface with the wastewater. The moving push plates 8 push the wastewater towards the top of the treatment channel 7. The push plates 8 on rotating ring 2 13 within the return channel 6 are in a position... In the tilted state, the push plate 8 will not cause significant disturbance to the wastewater in the return channel 6, and the reverse movement of rotating ring 11 and rotating ring 2 13 will not cause the push plate 8 to collide. In the other return channel 6, the push plate 8 on rotating ring 2 13 is in an upright state, and the push plate 8 on rotating ring 11 is in a tilted state. This allows the wastewater in both return channels 6 to flow upward and accumulate at the top of the treatment channel 7. By utilizing the synchronous reverse rotation of rotating ring 11 and rotating ring 2 13 and the rotatable setting of the push plate 8 on the corresponding rotating ring 11 or rotating ring 2 13, it can be ensured that the wastewater in the two return channels 6 always flows in one direction.

[0025] Furthermore, two annular grooves are provided on the side wall of the fixed ring 14, which are distributed in an inner and outer manner. The annular grooves include an arc groove 16, an arc groove 2 17 and two transition grooves 18. The transition grooves 18 are used to connect the arc groove 16 and the arc groove 2 17. Several sliding pillars 19 are provided in the annular grooves, and the sliding pillars 19 are connected to the corresponding push plates 8. The push plate 8 is connected to the corresponding rotating ring 11 or rotating ring 13 via an elastic body 20.

[0026] The radius of the first arc groove 16 is not equal to the radius of the second arc groove 17. When the rotating ring 11 or the rotating ring 2 13 drives the push plate 8 to rotate, the push plate 8 drives the sliding column 19 to slide in the ring groove. If the radius of the first arc groove 16 is greater than the radius of the second arc groove 17, then when the sliding column 19 slides in the first arc groove 16, the push plate 8 on the rotating ring 11 is in a tilted state, and the push plate 8 on the rotating ring 2 13 is in an upright state. When the sliding column 19 slides in the second arc groove 17, the push plate 8 on the rotating ring 11 is in an upright state, and the push plate 8 on the rotating ring 2 13 is in a tilted state. If the radius of the first arc groove 16 is smaller than the radius of the second arc groove 17, then the tilted and upright states of the push plate 8 are reversed. Thus, by using the above structural method, the push plate 8 can be controlled. Its structure is simple and easy to operate. The elastic body 20 can provide elastic force for each push plate 8, preventing it from shaking randomly and improving the stability of the push plate 8's movement.

[0027] The transition groove 18 is used to allow the sliding column 19 to move smoothly between the first arc groove 16 and the second arc groove 17.

[0028] Furthermore, the exhaust structure includes an air guide chamber 21 opened in each filling body 5 and a number of air diffuser pipes 22 connecting the two filling bodies 5. The air diffuser pipes 22 are connected to the air guide chambers 21, and a number of air diffuser holes 23 are opened on the side wall of the air diffuser pipes 22.

[0029] The air guide chamber 21 is connected to an external air pump. The air pump can pressurize the external air and send it into the air guide chamber 21. The air in the air guide chamber 21 can enter the air diffuser 22 and be discharged through several air diffuser holes 23. This releases a large number of bubbles into the treatment channel 7, which facilitates the adsorption treatment of impurities in the wastewater by using the bubbles.

[0030] Furthermore, an air guide groove 24 is provided on the lower side inside the air diffuser 22, and a sealing body 25 is vertically slidably arranged inside the air diffuser 22. The side wall of the sealing body 25 is used to block the air diffuser hole 23, and the top of the sealing body 25 slides out of the air diffuser 22.

[0031] In its natural state, the wastewater pressure inside the sewage tank 1 acts on the top of the sealing body 25, keeping the sealing body 25 fixed inside the venting pipe 22. When external gas is pressurized and sent into the venting chamber 21, the gas in the venting chamber 21 can enter the venting groove 24 and exert an upward thrust on the bottom of the sealing body 25, causing the sealing body 25 to overcome the water pressure and float up. The sealing body 25 stops blocking the venting hole 23, and the gas in the venting groove 24 can be discharged into the wastewater through the venting hole 23. When the operation stops, the sealing body 25 will block the venting hole 23 again due to the water pressure, thereby preventing wastewater from entering the venting pipe 22 and the venting chamber 21.

[0032] Furthermore, the lower side of the vent 23 is densely covered with several protrusions 26.

[0033] When the sealing body 25 moves upward due to air pressure, the gap created by the misalignment between the bottom of the sealing body 25 and the lower side of the vent 23 allows gas to be discharged into the wastewater. At this time, the gap is small, so the air bubbles can block the wastewater and prevent it from entering the vent pipe 22. The setting of several protrusions 26 on the vent 23 can further divide the gap into multiple small areas, each of which can generate air bubbles independently, thus further improving the blocking effect of air bubbles on wastewater.

[0034] Furthermore, the overflow pipe 3 is rotatably mounted on the corresponding core disk 12 via an adjusting sleeve 27. Several slots 28 are provided on the outer wall of the adjusting sleeve 27 and on the core disk 12 for mutual cooperation. A movable sleeve 29 is slidably mounted on the overflow pipe 3. The movable sleeve 29 and the overflow pipe 3 are connected by an elastic body 30. Several locking ridges 31 are provided on the outer wall of the movable sleeve 29. The locking ridges 31 are slidably engaged with the slots 28 on the adjusting sleeve 27 and the slots 28 on the core disk 12.

[0035] The thrust provided by the elastic body 20 to the movable sleeve 29 allows the locking ridge 31 to simultaneously engage with the locking groove 28 on the adjusting sleeve 27 and the locking groove 28 on the core disk 12. Thus, the locking ridge 31 fixes the core disk 12 and the adjusting sleeve 27, preventing the overflow pipe 3 from rotating freely. When it is necessary to adjust the liquid level in the sewage tank 1, the movable sleeve 29 can be pushed to move, causing the locking ridge 31 to separate from the locking groove 28 on the core disk 12. Then, the adjusting sleeve 27 can be rotated, thereby causing the overflow pipe 3 to rotate. The position of the highest point on the overflow pipe 3 changes, thus adjusting the wastewater overflow height.

[0036] Furthermore, the processing equipment also includes a power unit, which includes a drive motor 32 fixed relative to the core disk 12. The output end of the drive motor 32 is provided with a transmission wheel 33. One side of the transmission wheel 33 is connected to the corresponding rotating ring 13, and the other side of the transmission wheel 33 is provided with a transmission wheel 34. The transmission wheel 34 and the corresponding rotating ring 11 are connected by a transmission wheel 35.

[0037] The drive motor 32 can drive the rotating ring 13 and the rotating ring 34 to rotate through the first transmission wheel 33. The second transmission wheel 34 drives the rotating ring 11 to rotate through the third transmission wheel 35, so that the first rotating ring 11 and the second rotating ring 13 are both in a rotating state and their rotation directions are opposite. In order to improve the stability of equipment operation, power units can be set at both ends of the sewage tank 1.

[0038] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
