[0002] With the large-scale development of livestock and poultry farming, the treatment of its highly polluting wastewater has become a critical link. Traditional treatment methods are prone to causing secondary pollution and resource waste. In particular, the wastewater generated by harmless treatment processes such as high-temperature rendering and biodegradation is rich in high concentrations of organic matter, residual pathogens, and nitrogen and phosphorus pollutants. Direct discharge poses a serious threat to the ecological environment. However, existing wastewater treatment equipment often faces bottlenecks such as low treatment efficiency, high operating energy consumption, and insufficient resource recovery rate when treating such special wastewater. Therefore, there is an urgent need to develop an intelligent wastewater treatment device that integrates efficient sterilization, deep detoxification, and resource conversion functions to achieve harmless wastewater treatment coupled with organic fertilizer production or bioenergy conversion, thereby aligning with the policy orientation of green agriculture and circular economy.

[0024] 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.

[0025] A device for the harmless treatment of waste liquid from the carcasses of diseased and dead livestock and poultry, referring to Figure 1 As shown, the system includes an air flotation oil removal component 1, which breaks down emulsified grease and generates microbubbles. These microbubbles adhere to pollutants and float to the surface, thus achieving primary separation of solid pollutants from liquids. Simultaneously, a conveying pump is installed on one side of the air flotation oil removal component 1 to transport the treated wastewater to subsequent treatment devices. This technology is existing. The air flotation oil removal component 1 is fixedly connected to one end of an output pipe 2, and the other end of the output pipe 2 is fixedly connected to one end of a valve 3. The other end of the valve 3 is fixedly connected to a liquid storage tank assembly 4. After the solid pollutants and liquid undergo preliminary separation by the air flotation oil removal component 1, the valve 3 is opened, and the liquid is conveyed through the output pipe 2 to the liquid storage tank assembly 4. The output pipe 2 is a rigid pipe. The liquid storage tank assembly 4 is connected to an extrusion component 5. The liquid introduced into the liquid storage tank assembly 4 contains both oil and water. After oil and water are introduced into the liquid storage tank assembly 4, valve 3 is closed. The oil droplets, after being demulsified by the air flotation oil removal assembly 1, float on the surface of the water because their density is less than that of water. This is an existing technology. At this time, the pneumatic extrusion assembly 5 extrudes the oil and water in the liquid storage tank assembly 4 from top to bottom. Since the oil floats on the surface of the water, when the extrusion assembly 5 extrudes the mixture, the water is squeezed out from the bottom of the liquid storage tank assembly 4 first. When the liquid level in the liquid storage tank assembly 4 is low, the extrusion assembly 5 stops working, so that the extrusion assembly 5 no longer exerts extrusion force on the liquid in the liquid storage tank assembly 4, that is, the liquid in the liquid storage tank assembly 4 is no longer squeezed out. The air flotation oil removal assembly 1 achieves rapid separation of emulsified oil through microbubble adhesion of pollutants to float and demulsification technology. After demulsification, the oil droplets naturally float to the surface due to the density difference, creating favorable conditions for subsequent extrusion separation and improving the oil recovery rate.

[0026] Reference Figures 1-4 As shown, the liquid storage tank assembly 4 is fixedly connected to one end of the conveying pipe 6, and the other end of the conveying pipe 6 is fixedly connected to one end of the water pressure chamber 7. Since the oil in the waste liquid cannot be completely demulsified, a small amount of oil will remain suspended in the water due to the lack of demulsification. Under the squeezing action of the squeezing assembly 5, since the valve 3 is closed at this time, the water squeezed out by the squeezing assembly 5 and the oil suspended in the water flow into the water pressure chamber 7 through the conveying pipe 6, thereby gradually increasing the liquid pressure in the water pressure chamber 7. The pressure-sensing plate assembly 8 is slidably connected in the water pressure chamber 7. When the liquid pressure in the water pressure chamber 7 increases, that is, the pressure on one side of the pressure-sensing plate assembly 8 increases, under the action of this pressure, the pressure-sensing plate assembly 8 slides in the water pressure chamber 7. When the pressure-sensing plate assembly 8 slides to the appropriate position in the water pressure chamber 7, the pressure-sensing plate assembly 8 loses its blocking effect on the mixture of oil and water. At this time, the mixture, i.e., the waste liquid, flows past the pressure-sensing plate assembly 8 to the other end of the water pressure chamber 7. When the liquid level in the liquid storage tank assembly 4 is low, the squeezing assembly 5 resets. At this time, the water pressure in the water pressure chamber 7 drops sharply, which in turn causes the pressure on the pressure-sensing plate assembly 8 to drop sharply. The pressure-sensing plate assembly 8 then gradually resets. The other end of the water pressure chamber 7 is fixedly connected to one end of the double-cone tube 9. After the waste liquid flows out from the other end of the water pressure chamber 7, it enters the double-cone tube 9. The other end of the double-cone tube 9 is fixedly connected to the disinfection assembly 10. (Refer to...) Figure 1 , Figure 4 and Figure 5As shown, an isolation tube 20 is fixedly connected inside the double conical tube 9. The isolation tube 20 is coaxially arranged with the double conical tube 9. A working cavity 30 is formed between the outer wall of the isolation tube 20 and the inner wall of the double conical tube 9. Two drive assemblies 40 are fixedly connected inside the working cavity 30. A rotating tube assembly 50 is rotatably connected inside the double conical tube 9. The rotating tube assembly 50 is coaxially arranged with the double conical tube 9 and is connected to the drive assembly 40. The outer diameter of the rotating tube assembly 50 is exactly equal to the inner diameter of the isolation tube 20, that is, the outer wall of the rotating tube assembly 50 is close to the inner wall of the isolation tube 20. An adsorption assembly 60 is slidably connected inside the rotating tube assembly 50. The adsorption assembly 60 can slide axially back and forth inside the rotating tube. The adsorption assembly 60 is rotatably connected to the pressure plate assembly 8. When the waste liquid entering the water pressure chamber 7 squeezes the pressure plate assembly 8, the pressure plate assembly 8 slides inside the water pressure chamber 7, thereby driving the adsorption assembly 60 to slide axially inside the rotating tube. When the pressure plate assembly 8 resets, it drives the adsorption assembly 60 to slide in the opposite direction inside the rotating tube. After the waste liquid enters the interior of the double conical tube 9 from one end, it flows to the other end. During this process, the waste liquid passes through the adsorption assembly 60, and the adsorption assembly 60 adsorbs the undemulsified oil in the waste liquid. Then the waste liquid flows out from the other end of the double conical tube 9 and enters the disinfection assembly 10 for disinfection. An ultrasonic distance sensor 70 is fixedly connected inside the rotating tube assembly 50. When the ultrasonic distance sensor 70 detects that the distance between it and the adsorption assembly 60 increases, it controls the drive assembly 40 to rotate at a certain angle. When the ultrasonic distance sensor 70 detects that the distance between it and the adsorption assembly 60 decreases, it controls the drive assembly 40 to reset.

[0027] Reference Figure 3 As shown, the liquid storage tank assembly 4 includes a storage tank 41, with an inlet 42 and an outlet 43 fixedly connected to the storage tank 41. The other end of the valve 3 is fixedly connected to the inlet 42. When the valve 3 is opened, waste liquid enters the storage tank 41 through the valve 3 and the inlet 42. The direct connection between the inlet 42 and the valve 3 ensures rapid introduction of waste liquid. The outlet 43 facilitates the discharge or transfer of wastewater, forming a unidirectional flow path to avoid cross-contamination. The storage tank 41 is also fixedly connected to the outlet 43, which is fixedly connected to one end of the conveying pipe 6. A sealing cover 44 is fixedly connected to the upper end of the storage tank 41. The modular design facilitates the maintenance of the valve 3 or the cleaning of the storage tank 41. At the same time, the sealing cover 44 can be designed to be detachable for convenient internal inspection or expansion.

[0028] The extrusion assembly 5 includes a motor 51. After valve 3 is opened, waste liquid is transported from the air flotation oil removal assembly 1 to the storage tank 41. After the waste liquid is transported, valve 3 is closed, and motor 51 is started to rotate. Motor 51 is fixedly connected to the upper end of the closed cover 44. The output end of motor 51 is fixedly connected to one end of lead screw 52. When motor 51 rotates, it drives lead screw 52, ​​which is fixedly connected to it, to rotate synchronously. Lead screw 52 and extrusion plate 53 are threaded together. Extrusion plate 53 is slidably connected to the storage tank 41. When lead screw 52 rotates, through its engagement with the thread on extrusion plate 53, extrusion plate 53 slides towards the bottom of storage tank 41. Since most oil droplets float on the water surface after demulsification, the lower surface of extrusion plate 53 slides towards the bottom of storage tank 41, causing the oil droplets to... When the waste liquid comes into contact with the liquid surface, as the extrusion plate 53 continues to slide downwards, it generates extrusion force on the waste liquid, causing the waste liquid at the bottom of the storage tank 41 to be squeezed out from the outlet 43 and then into the conveying pipe 6, and subsequently into the hydraulic chamber 7. The oil droplets on the upper surface of the liquid in the storage tank 41 remain inside the storage tank 41. When the liquid level in the storage tank 41 is low, the motor 51 rotates in the reverse direction, which in turn drives the lead screw 52 to rotate in the reverse direction, causing the extrusion plate 53 to slide away from the bottom of the storage tank 41. At this time, the pressure at the bottom of the storage tank 41 decreases drastically, and the waste liquid in the storage tank 41 stops flowing into the hydraulic chamber 7. The reverse lifting of the extrusion plate 53 can prevent grease from mixing into the hydraulic chamber 7, ensuring the purity of subsequent processing. Since the components in the waste liquid in the storage tank 41 are relatively soft, they will not affect the fit between the lead screw 52 and the thread, that is, they will not affect the up and down movement of the extrusion plate 53.

[0029] Reference Figures 4-8 As shown, the water pressure chamber 7 is tubular. One end of the water pressure chamber 7 is fixedly connected to one end of the connecting pipe 71, and the other end of the connecting pipe 71 is fixedly connected to the other end of the conveying pipe 6. The outer diameter of the connecting pipe 71 is smaller than the inner diameter of the water pressure chamber 7. After the waste liquid enters the connecting pipe 71 from the conveying pipe 6, it continues to flow and enters the water pressure chamber 7, increasing the water pressure inside the water pressure chamber 7. The other end of the water pressure chamber 7 is fixedly connected to one end of the single conical pipe 72, with the larger diameter end of the single conical pipe 72. The water pressure chamber 7 is also fixedly connected to one end of the barrier pipe 73, the inner diameter of which is larger than the outer diameter of the connecting pipe 71. The outer diameter of the barrier pipe 73 is smaller than the inner diameter of the water pressure chamber 7, and the length of the barrier pipe 73 is smaller than the length of the water pressure chamber 7. A waste liquid outlet 74 is opened on the wall of the barrier pipe 73. A limit ring 75 is fixedly connected to the other end of the barrier pipe 73. After the waste liquid enters the connecting pipe 71 from the conveying pipe 6, it continues to flow and enters the barrier pipe 73, which increases the water pressure in the barrier pipe 73. The size difference between the connecting pipe 71, the water pressure chamber 7 and the barrier pipe 73 forms a dynamic pressure buffer. After the waste liquid enters the barrier pipe 73 from the conveying pipe 6 through the connecting pipe 71, the pressure gradually accumulates due to the expansion of the cavity volume, which enhances the system's adaptability to water pressure fluctuations.

[0030] Pressure plate assembly 8 includes a pressure plate body 81, which is slidably connected inside the barrier tube 73. One end of the pressure plate body 81 is fixedly connected to a sliding rod 82. An isolation cover 83 is fixedly connected to the sliding rod 82 and slidably connected to the barrier tube 73. The inner wall of the isolation cover 83 is flush with the outer wall of the barrier tube 73. A connecting ring 84 is fixedly connected to one end of the isolation cover 83. The connecting ring 84 is fixedly connected to one end of several return springs 85. The other end of each return spring 85 is connected to the water pressure chamber 7. The fixed connection has a waste liquid outlet 86 on the isolation cover 83. After the waste liquid enters the connecting pipe 71 from the conveying pipe 6, it continues to flow into the barrier pipe 73, which increases the water pressure in the barrier pipe 73. The water pressure overcomes the resistance of the return spring 85 and pushes the pressure plate body 81 to slide towards the limit ring 75 in the barrier pipe 73. During the process of sliding towards the limit ring 75, the pressure plate body 81 drives the sliding rod 82, the isolation cover 83 and the connecting ring 84 to move synchronously. At the same time, the return spring 85 is stretched. When the pressure-sensing plate body 81 slides to the position where it abuts against the limiting ring 75, the positions of waste liquid outlet 2 86 and waste liquid outlet 1 74 coincide. At this time, waste liquid flows out from the positions of waste liquid outlet 2 86 and waste liquid outlet 1 74 and then enters the water pressure chamber 7. The continuous squeezing of the waste liquid in the storage tank 41 by the squeezing plate 53 causes the waste liquid in the water pressure chamber 7 to gradually increase. When the liquid level in the storage tank 41 is low, the squeezing plate 53 moves upward. At this time, the liquid pressure at the bottom of the storage tank 41 is small, and the return spring 85 overcomes the liquid pressure on the pressure-sensing plate body 81. The pressure action causes the connecting ring 84, isolation cover 83, sliding rod 82, and pressure-sensing plate body 81 to reset. At this time, waste liquid outlet 1 74 and waste liquid outlet 2 86 reset synchronously, i.e., staggered. The tight sliding cooperation between isolation cover 83 and barrier tube 73, combined with the reset capability of reset spring 85, effectively prevents waste liquid backflow, maintains the system's sealing integrity, and reduces the risk of contamination. Through the linkage between extrusion plate 53 and pressure-sensing plate, the system can dynamically adjust the waste liquid release rhythm according to the liquid level in storage tank 41, optimize resource utilization, and reduce energy consumption.

[0031] Reference Figure 1 , Figure 5 , Figure 6 , Figure 9 and Figure 10As shown, one end of the double-conical tube 9 is fixedly connected to the smaller diameter end of the single-conical tube 72. The double-conical tube 9 has a grease outlet 3 91. The isolation tube 20 has a Z-shaped cross-section and is coaxially arranged with the double-conical tube 9. The isolation tube 20 has a grease outlet 1 201, which coincides with the position of the grease outlet 3 91. When the positions of the waste liquid outlet 2 86 and the waste liquid outlet 1 74 correspond, the waste liquid flows out from the position where the waste liquid outlet 2 86 and the waste liquid outlet 1 74 coincide, and then enters the hydraulic chamber 7. The continuous squeezing of the waste liquid in the storage tank 41 by the squeezing plate 53 causes the waste liquid in the hydraulic chamber 7 to gradually increase, thus causing the waste liquid to flow through the single-conical tube 72. The grease is introduced into the double conical tube 9. Below the grease outlet 91, a sludge collection tank 92 is provided. A partition 93 is fixedly connected inside the sludge collection tank 92. An installation plate 97 is provided at the bottom of the sludge collection tank 92. A slide rail 96 is fixedly connected to the installation plate 97. The sludge collection tank 92 is slidably connected to the slide rail 96. A cylinder 94 is fixedly connected to the installation plate 97. The output end of the cylinder 94 is fixedly connected to the sludge collection tank 92. A water pump 95 is fixedly connected to the installation plate 97. The outlet end of the water pump 95 is connected to the inlet 42 through a branch pipe, and the inlet end is connected to the sludge collection tank 92 through a hose. At the same time, the position of the sludge collection tank 92 is located on the right side of the partition 93, which can pump the wastewater on the right side of the partition 93 into the storage tank 41.

[0032] The drive assembly 40 includes a second motor 401, which is fixedly connected to the working cavity 30 formed between the outer wall of the isolation tube 20 and the inner wall of the double conical tube 9. The output end of the second motor 401 is fixedly connected to the gear 402.

[0033] The rotating tube assembly 50 includes a rotating tube body 501. A straight groove 502 is provided on the inner wall of the rotating tube body 501. The straight groove 502 is arranged along the axial direction of the rotating tube body 501. A second grease outlet 503 is provided on the rotating tube body 501. When the extrusion plate 53 stops extruding the wastewater, the second motor 401 is reset.

[0034] The rotating tube body 501 is rotatably connected inside the double conical tube 9. The outer wall of the rotating tube body 501 is in close contact with the inner wall of the isolation tube 20. A toothed ring 504 is fixedly connected to the outer wall of the rotating tube body 501, and the toothed ring 504 meshes with the gear 402.

[0035] The adsorption assembly 60 includes a circular plate 601, a slider 602 fixedly connected to the circular plate 601, the slider 602 slidably connected within a straight groove 502, a corrugated plate 603 provided within the straight groove 502 to prevent grease from entering and causing blockage, a plurality of flow ports 604 opened on the circular plate 601, the circular plate 601 being rotatably connected to a sliding rod 82, limit blocks 605 provided on both sides of the circular plate 601, the limit blocks 605 being fixedly connected to the sliding rod 82, and a filter membrane 606 fixedly connected to the circular plate 601. After entering the double conical tube 9, it flows through the inner cavity of the rotating tube body 501 and flows out from the other end of the double conical tube 9, entering the disinfection component 10. Engineered bacteria are added to the disinfection component 10 to degrade organic pollutants. The filter membrane 606 is made of polyethylene material. Through surface polarity modification and multi-level pore structure design, it has a strong adsorption effect on undemulsified grease. When the extrusion plate 53 is in the initial position, that is, when the extrusion plate 53 has not moved downward to extrude waste liquid, the grease discharge outlet 1 201 and the grease discharge outlet 2 503 are staggered. When the extrusion plate 53 extrudes the waste liquid, the sliding rod 82 slides, causing the circular plate 601 and the filter membrane 606 to slide synchronously. At this time, the slider 602 slides within the straight groove 502, increasing the distance between the circular plate 601 and the ultrasonic distance sensor 70. This causes the control system to control the motor 401 to rotate by an angle, causing the gear 402 and the gear ring 504 to rotate synchronously. When the gear ring 504 rotates, it drives the rotating tube body 501, which is fixedly connected to it, to rotate by an angle, causing the grease outlet 201 and the grease outlet 503 to be misaligned. At this time, the waste liquid will not pass through the grease outlet 201, the grease outlet 503, and the grease. When the rotating tube body 501 of outlet 3 91 rotates, it drives the slider 602 to rotate synchronously, which in turn drives the circular plate 601 and the filter membrane 606 fixedly connected to it to rotate synchronously by an angle. When the sliding rod 82 is reset, it drives the slider 602 to slide in the opposite direction in the straight groove 502, which in turn drives the circular plate 601 and the filter membrane 606 to slide in the opposite direction. At the same time, the ultrasonic distance sensor 70 detects that the distance between the circular plate 601 and the sensor gradually decreases until the circular plate 601 is completely reset. During this process, the motor 2 401 rotates in the opposite direction by an angle, that is, resets, so that the grease outlet 1 201 coincides with the grease outlet 2 503 and the grease outlet 3 91.

[0036] At this time, a small amount of water in the inner cavity of the rotating tube body 501 flows into the sludge collection tank 92 through the grease outlet 1 201, grease outlet 2 503, and grease outlet 3 91, i.e., the right side of the partition 93. Then, the water pump 95 transports a small amount of wastewater to the storage tank 41. Then, the extension and retraction of the cylinder 94 allows the sludge collection tank 92 to slide on the slide rail 96, so that the left side of the partition 93 is directly below the grease outlet 1 201, grease outlet 2 503, and grease outlet 3 91. Then, the control system controls the motor 2 401 to rotate at high speed, which in turn causes the rotating tube body 501 to rotate at high speed, causing the circular plate 601 and the filter membrane 606 to rotate synchronously. At this time, the grease outlet 1 201, grease outlet 2 503, and grease outlet 3 91 rotate at high speed. The positions of outlet 3 91 coincide. That is, when the circular plate 601 is in the initial position, when the circular plate 601 drives the filter membrane 606 to rotate at high speed, the centrifugal force is used to throw out the grease adhering to the filter membrane 606. Then, it passes through grease outlet 1 201, grease outlet 2 503 and grease outlet 3 91 and falls into the sludge collection bucket 92 under the action of gravity, that is, the left side of the partition 93. When a suitable amount is collected, it can be manually collected and processed. The extension and retraction of the cylinder 94 can make the sludge collection bucket 92 slide left and right on the slide rail 96 so that the positions of grease outlet 1 201, grease outlet 2 503 and grease outlet 3 91 correspond to the left or right side of the partition 93, so that the wastewater and grease fall to the right or left side of the partition 93 respectively.
