Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of livestock slaughtering, in particular to an automatic pig unhaired equipment and method. BACKGROUND

[0002] Pig slaughtering is an important link in the meat industry, and pig unhaired is an essential process. In the existing pig unhaired equipment, a large amount of hot water is usually used to soak and flush the pig body to soften the skin, facilitate unhaired and maintain hygiene. However, this process produces a large amount of industrial wastewater mixed with pig hair, grease, blood, dirt and various microorganisms.

[0003] Currently, the treatment of such wastewater generally has some shortcomings. First, after the pig hair is mixed with the wastewater, it is easy to cause blockage of the pipeline and subsequent treatment equipment. The traditional manual salvage or simple filtration method not only has low processing efficiency and high labor intensity, but also greatly reduces the recycling value of the pig hair. Second, the unhaired wastewater contains a large amount of grease and organic pollutants. If it is directly discharged, it will not only cause serious environmental pollution and not meet the increasingly strict environmental protection regulations, but also waste a lot of water resources.

[0004] In order to save costs, some equipment tries to recycle the unhaired wastewater. However, these recycling systems often lack efficient and deep treatment links. The oil inside the untreated wastewater will accumulate and affect the efficiency of the heating and conveying equipment. More seriously, the bacteria and other microorganisms remaining and breeding in the wastewater may enter the pork through the skin damage caused by the unhaired process when the wastewater is recycled and sprayed on the pig body, causing secondary pollution and potential food safety hazards.

[0005] Therefore, the existing technology generally lacks an integrated solution that can efficiently separate pig hair, deeply purify wastewater and realize safe and automatic recycling. This leads to problems such as low efficiency, resource waste, environmental pollution and health risks in the unhaired process. SUMMARY

[0017] A second aspect of the present invention provides an automated method for scraping hair off pigs, comprising the following steps: S1. Start the scraping roller to scrape the hair off the scalded pigs. At the same time, start the centrifugal pump of the spray assembly to spray the hot water in the heating tank onto the pigs through the spray pipe. S2. Use a jet pipe to periodically spray hot water to wash the pig hair adhering to the filter plate. The controller controls the electric push rod to drive the baffle to rotate and open the gap, so that the pig hair is discharged into the drainage pipe. S3. Use a sewage pump to send sewage into the filter assembly. Use a low-level oil stain detector to monitor the oil stain content in real time. When the oil stain layer reaches the preset value of the lower detector, the controller controls solenoid valve one to close, so that the water level in the filter box rises. When the high-level oil stain detector detects that the oil stain content has decreased, solenoid valve one is reopened to discharge the water. At the same time, solenoid valve two is opened periodically to discharge the sludge that has settled at the bottom of the filter box. S4. The water treated in step S3 is introduced into the disinfection tank through connecting pipe three. Ozone is introduced into the water through the ozone tube.

Once the water quality meets the standards, start centrifugal pump two to pump the disinfected clean water into the heating tank for heating. The heated water is then used as a heat source to supply the spray assembly for recycling.

[0018] This invention provides an automated pig hair removal device and method. It has the following beneficial effects: 1. This invention uses an inclined filter plate to initially separate pig hair and water, then uses a spray pipe to periodically rinse and collect the pig hair. Subsequently, the opening and closing of the baffle is controlled by an electric push rod, which can automatically discharge the collected pig hair from a dedicated drain outlet at regular intervals. This achieves rapid and effective solid-liquid separation, avoids pig hair clogging subsequent processing equipment, and improves the efficiency and quality of pig hair recycling.

[0019] 2. This invention utilizes an air pump and aeration pipe to aerate wastewater, causing grease to float to the surface through air flotation. Simultaneously, by setting up two oil stain detectors at different heights and linking them with solenoid valves, the invention can intelligently determine the degree of oil accumulation and automatically control the drainage and oil discharge process, reducing manual intervention, achieving high separation efficiency, and ensuring the water quality entering the next treatment stage.

[0020] 3. In this invention, the wastewater after solid-liquid separation and oil-water separation enters a disinfection tank for sterilization and disinfection with ozone. The water quality is monitored in real time by a water quality monitor to ensure that it meets safety standards. The purified water that meets the standards is then sent back to the heating tank for reheating and reused as hot water for spraying. This not only saves water resources in the production process, but also saves more energy and reduces production costs because the circulating water is already at a certain temperature compared to directly heating cold water. At the same time, it avoids the risk of bacteria exceeding the standard in the water entering the pigs through broken skin during spraying and contaminating the pigs. Attached Figure Description

[0023] The technical solutions in 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.

[0024] Please see the appendix Figure 1 - Appendix Figure 7 This invention provides an automated pig hair removal device and method, including a housing 1, a scalding tank 2, a tipping bucket 3, a hair removal roller 4, a controller 7, and a shielding fence 25. A spray assembly is installed on the top of the housing 1, a solid-liquid separation assembly is installed in the middle of the housing 1, a sewage pump 30 is fixedly connected to the bottom of the housing 1, the input end of the sewage pump 30 passes through and is fixedly connected to the bottom of the housing 1, a connecting pipe 9 is fixedly connected to the output end of the sewage pump 30, an oil-liquid separation assembly is installed at the other end of the connecting pipe 9, a disinfection assembly is installed at the other end of the oil-liquid separation assembly, a heating tank 11 is installed at the other end of the disinfection assembly, the scalding tank 2 is installed on the outside of the housing 1, and an inlet pipe 23 and a drain pipe 24 are respectively installed on the outside of the scalding tank 2. In one specific embodiment, the pigs after being scalded in the scalding pool 2 are sent to the scraping roller 4 by the tipping bucket 3. With the help of the water inlet pipe 23 and the drain pipe 24, the water in the scalding pool 2 can be replaced in time, so that the scraping roller 4 can scrape off the pig hair by rotating. And with the blocking barrier 25 blocking the way, the pigs can be prevented from rolling down in the direction of rotation. At the same time, after scraping, the blocking barrier 25 is lifted by the pulling mechanism, so that the pigs can roll out with the rotation.

[0025] See appendix Figure 1 - Appendix Figure 4 The solid-liquid separation assembly includes a flow guide ring 28, which is fixedly connected to the inner wall of the housing 1. A filter plate 29 is fixedly connected to the bottom of the flow guide ring 28. A spray pipe 26 is fixedly connected to the middle of the filter plate 29. One end of the spray pipe 26 penetrates the outer wall of the housing 1. A flow guide shell 22 is fixedly connected to the inner bottom of the housing 1. An electric push rod 34 is fixedly connected to the inner wall of the housing 1. A baffle 31 is rotatably connected to the middle of the housing 1. The output end of the electric push rod 34 is fixedly connected to the outside of the baffle 31. A notch 33 is opened on the outer wall of the flow guide shell 22. A drain outlet 32 ​​is opened at the bottom of the housing 1. A rubber pad 41 is fixedly connected to the side of the baffle 31 near the notch 33. The outer diameter of the rubber pad 41 is larger than the outer diameter of the notch 33. A flow guide pipe 27 is fixedly connected to the bottom of the housing 1. The flow guide pipe 27 is located below the drain outlet 32. The electric push rod 34 and the baffle 31 are both located in the middle of the flow guide shell 22. An inclined surface is provided on the top of the flow guide shell 22. In one specific embodiment, while the pig is being scraped on the scraping roller 4, the spray assembly sprays hot water to prevent the pig hair from splashing and to ensure that the temperature of the pig does not drop. After the pig hair is scraped, the shield 25 is raised so that the pig can fall onto the guide shell 22 as the scraping roller 4 rotates, and roll down under the guidance of the inclined surface of the guide shell 22. The hot water washes the pig hair onto the filter plate 29, and the guide ring 28 prevents the pig hair stains from sticking to the protrusions of the filter plate 29, thereby quickly separating the pig hair from the sewage. The spray pipe 26 is connected to the water supply equipment so that the spray pipe 26 can spray hot water to wash the pig hair on the filter plate 29. The hot water can dissolve the grease and prevent the pig hair from sticking to the grease, thereby washing the pig hair to the bottom of the inclined surface of the filter plate 29. The electric push rod 34 is driven to pull the baffle 31 to rotate, so that the baffle 31 drives the rubber pad 41 to separate from the notch 33, so that the pig hair can fall out through the notch 33 and fall into the drain pipe 27 through the sewage outlet 32, and slide out with the drain pipe 27, thereby quickly separating the pig hair from a large amount of sewage and improving the recycling efficiency and quality of pig hair.

[0026] See appendix Figure 1 - Appendix Figure 3 The spray assembly includes a centrifugal pump 5, which is fixedly connected to the top of the housing 1. The input end of the centrifugal pump 5 is fixedly connected to a return pipe 15, and the other end of the return pipe 15 passes through and is fixedly connected to the middle of the top wall of the heating tank 11. The output end of the centrifugal pump 5 is fixedly connected to a spray pipe 6, and the other end of the spray pipe 6 passes through and is fixedly connected to the middle of the top wall of the housing 1. In one specific embodiment, the centrifugal pump 5 can draw the heated water from the heating tank 11 through the return pipe 15 and spray it onto the pigs through the spray pipe 6, thereby preventing pig hair from splashing, ensuring the temperature of the pigs, and improving the convenience of hair removal.

[0027] See appendix Figure 1 Appendix Figure 2 Appendix Figure 5 and attached Figure 6 The oil-liquid separation assembly includes a filter box 8, which is fixedly connected to the end of the connecting pipe 1 9 away from the housing 1. The outer wall of the filter box 8 has an oil drain port 44. The inner top of the filter box 8 is fixedly connected to two partitions 2 38, and the inner bottom of the filter box 8 is fixedly connected to a partition 1 37. Both sides of the outer wall of the partition 1 37 are fixedly connected to oil stain detectors 36. The outer side of the filter box 8 is fixedly connected to an air pump 19, and the output end of the air pump 19 is fixedly connected to an aeration pipe 20. The other end of the aeration pipe 20 is fixedly connected to the middle of the filter box 8. The middle of the outer wall of the filter box 8 is fixedly connected to a drain pipe 21, and a solenoid valve 2 40 is installed in the middle of the drain pipe 21. The middle of the outer wall of the filter box 8 is fixedly connected to a connecting pipe 3 35, and a solenoid valve 1 12 is installed in the middle of the connecting pipe 3 35. The inner bottom of the filter box 8 is fixedly connected to multiple guide pipes 39, and the drain pipe 21 is located between two adjacent guide pipes 39. In one specific embodiment, the filtered sewage can be sent into the filter box 8 through the connecting pipe 9 by the sewage pump 30. In the filter box 8, the sewage can be separated and settled by the action of the partition 38 and the partition 37. At the same time, the air pump 19 introduces outside air into the sewage through the aeration pipe 20, thereby forming a large number of tiny bubbles in the sewage. Under the action of air flotation, the oil in the sewage can be adsorbed, so that the oil can quickly and completely float to the surface. Since the density of oil is lower than that of water, it can always float on the water surface under the action of air flotation, so that the water can squeeze the oil out through the oil outlet 44. The filtered and settled water can be output through the connecting pipe 35. Meanwhile, the two oil stain detectors 36 at different heights on the partition 37 can detect oil stains in the water. When the bottom oil stain detector 36 detects a large amount of oil in the water, the controller 7 will control the solenoid valve 12 to temporarily close, which will increase the water in the filter box 8 and discharge the water containing a large amount of oil through the oil drain port 44. When the oil stain detector 36 detects a decrease in oil, the solenoid valve 12 will open and continue to supply water. At the same time, under the action of the guide pipe 39 in the filter box 8, the settled sludge can be collected. Through the connection of the external sludge pump to the sewage pipe 21, the sludge at the bottom of the filter box 8 will be pumped out after the solenoid valve 20 opens, so as to avoid clogging the filter box 8.

[0028] See appendix Figure 1 Appendix Figure 2 and attached Figure 7The disinfection assembly includes a disinfection tank 10 and a stirring assembly. The disinfection tank 10 is fixedly connected to the end of the connecting pipe 35 away from the filter box 8. An ozone tube 18 is installed at the bottom of the disinfection tank 10. The end of the ozone tube 18 penetrates the inner wall of the disinfection tank 10. A water quality monitor 13 is fixedly connected to the middle of the top wall of the disinfection tank 10. A centrifugal pump 2 17 is fixedly connected to the outside of the disinfection tank 10. The input end of the centrifugal pump 2 17 penetrates and is fixedly connected to the outer wall of the disinfection tank 10. The output end of the centrifugal pump 2 17 is fixedly connected to a connecting pipe 2 16. The other end of the connecting pipe 2 16 is fixedly connected to the middle of the top wall of the heating tank 11. In one specific embodiment, the filtered and settled water can enter the disinfection tank 10 through the connecting pipe 35. The water in the disinfection tank 10 can be detected by the water quality monitor 13. When the bacterial content in the water is high, ozone can be continuously introduced into the water through the ozone tube 18 via an external ozone generator. As a strong oxidant, ozone can quickly destroy the cell wall of bacteria, with extremely high sterilization efficiency and no dead spots. At the same time, it can oxidize and decompose organic pollutants such as blood and secretions in the water, thereby decolorizing, deodorizing, and reducing the chemical oxygen demand of the water. When the water quality monitor 13 detects that the bacterial content in the water meets the standard, the centrifugal pump 2 17 will draw out the water from the disinfection tank 10 and input it into the heating tank 11 through the connecting pipe 2 16 for heating, thereby preventing the bacterial content in the water from exceeding the standard and entering the pigs through broken skin during spraying, thus contaminating the pigs.

[0029] See appendix Figure 7 The stirring assembly includes a servo motor 14, which is fixedly connected to the top of the sterilization tank 10. A rotating rod 42 is fixedly connected to the output end of the servo motor 14, and a stirring blade 43 is fixedly connected to the outer periphery of the rotating rod 42. In one specific embodiment, while ozone is continuously input into the ozone tube 18, the servo motor 14 drives the rotating rod 42 to rotate, so that the stirring blade 43 mixes the ozone and water to ensure the sterilization and deodorization effect.

[0030] An automated method for removing hair from pigs includes the following steps: S1. Start the scraping roller 4 to scrape the hair off the scalded pigs. At the same time, start the centrifugal pump 5 of the spray assembly to spray the hot water in the heating tank 11 onto the pigs through the spray pipe 6. S2. Use the spray pipe 26 to periodically spray hot water to wash the pig hair stuck on the filter plate 29. The controller 7 controls the electric push rod 34 to drive the baffle 31 to rotate and open the notch 33, so that the pig hair is discharged into the drainage pipe 27. S3. Sewage pump 30 is used to send sewage into the filter assembly. The oil content is monitored in real time by the low-level oil stain detector 36. When the oil layer reaches the preset value of the lower detector, the controller 7 controls the solenoid valve 12 to close, so that the water level in the filter box 8 rises. When the oil content detected by the high-level oil stain detector 36 decreases, the solenoid valve 12 is reopened to discharge the water. At the same time, the solenoid valve 2 40 is opened periodically to discharge the sludge that has settled at the bottom of the filter box 8. S4. The water treated in step S3 is introduced into the disinfection tank 10 through the connecting pipe 35. Ozone is introduced into the water through the ozone pipe 18. At the same time, the stirring component is used to make the ozone and water fully mixed for sterilization, deodorization and decolorization. The water quality monitoring instrument 13 is used to monitor the water quality indicators in the disinfection tank 10 in real time to see if they meet the standards. S5. Once the water quality meets the standards, start centrifugal pump 17 to pump the disinfected clean water into heating tank 11 for heating. The heated water is then used as a heat source to supply the spray assembly for recycling.

[0031] Working principle: First, when the tipping bucket 3 feeds the pig onto the scraping roller 4 for scraping, the spray assembly sprays hot water to rinse it, preventing the pig's body temperature from dropping and preventing pig hair from splashing. At the same time, the pig hair and dirt on the pig's body surface fall into the filter plate 29 with the water. Under the action of the inclined filter plate 29, the pig hair can be separated from the sewage. Then, it is connected to the external pump body through the spray pipe 26, so that the pig hair is rinsed with hot water periodically. Under the action of hot water rinsing, the water and dirt stuck to the pig hair can be washed to the bottom of the filter plate 29 and accumulated. The electric push rod 34 drives the baffle 31 to rotate, so that the baffle 31 moves the rubber pad 41 away from the notch 33, so that the pig hair can fall into the drain pipe 27 through the notch 33 and the sewage outlet 32, and slide out with the drain pipe 27, thereby quickly separating the pig hair from a large amount of sewage and improving the pig hair recovery efficiency.

[0032] Under the action of the sewage pump 30, the separated sewage can be input into the filter box 8 through the connecting pipe 1 9. The sewage will enter the middle position of the filter box 8 through the gap between the partition 2 38 and the filter box 8. At the same time, the air pump 19 drives the air to input into the sewage through the aeration pipe 20. Under the action of air flotation, the oil in the sewage can be adsorbed and floated. The sludge will accumulate at the bottom of the filter box 8. The filtered and settled water will be discharged through the connecting pipe 3 35. At the same time, under the detection of two oil stain detectors 36 at different heights, when the oil stain content is high and detected by the lower oil stain detector 36, the solenoid valve 1 12 is closed to reduce the water discharge. This causes the water in the filter box 8 to increase and squeeze the oil stains out through the oil drain port 44. When the oil stain content detected by the upper oil stain detector 36 decreases, the solenoid valve 1 12 is discharged, and water continues to be output through the connecting pipe 3 35.

[0033] After water is introduced into the disinfection tank 10, the water quality monitor 13 inside the disinfection tank 10 can detect the wastewater in the water. Ozone is continuously introduced into the water in the disinfection tank 10 through an external ozone generator connected to the ozone pipe 18. At the same time, when the water quality monitor 13 detects that the bacteria in the water reaches the safety standard, the centrifugal pump 17 will extract the wastewater from the disinfection tank 10 and introduce it into the heating tank 11 through the connecting pipe 16 for heating and recycling. This avoids the bacteria content in the water exceeding the standard and entering the pigs through broken skin during spraying, thus preventing contamination of the pigs.
