Description

Technical Field

[0001] This invention relates to the field of pig slaughtering technology, specifically a pre-cleaning device for pig slaughtering. Background Technology

[0002] Post-slaughter cleaning of pigs is a crucial step in ensuring pork safety. This step effectively removes blood, hair, impurities, and potential pathogenic microorganisms that may have accumulated during slaughter, significantly reducing the risk of microbial contamination and cross-infection. Simultaneously, cleaning provides a clean surface for subsequent inspection and quarantine. Proper cleaning procedures are essential for ensuring the hygienic quality of pork, extending its shelf life, and providing consumers with safe and reliable meat products.

[0003] A search revealed that patent document CN221843661U discloses an integrated production line for spiral hair removal, singeing, and polishing. The production line includes a hair removal device and a singeing and polishing device. The hair removal device has a pig carcass receiving platform at its inlet and a pig carcass receiving platform at its outlet. A pre-drying device is provided between the hair removal device and the singeing and polishing device. The inlets and outlets of adjacent devices are connected by a chute. The production line also includes a control box to control the hair removal process.

[0004] The aforementioned design eliminates the need for separate hanging conveyors, pre-dryers, singeing machines, and polishing and cleaning machines for pig carcasses. It integrates the traditional hanging pre-drying, singeing, and polishing / cleaning processes into a single unit, completing the entire process in 1.5 minutes. By simplifying the production process, it shortens the slaughtering line by approximately 20 meters, reduces pig slaughtering and processing time by more than 5 minutes, and saves on factory construction and equipment costs. It also improves pork quality and the working environment for employees. However, in actual use, the water used for washing the pigs is directly discharged after cleaning, which easily leads to a significant waste of water resources.

[0005] Therefore, a pre-cleaning device for slaughtered pigs is proposed to address the above problems. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies and solve the problem of water being directly discharged after pig washing, this invention proposes a pre-washing device for slaughtered pigs.

[0007] A pre-cleaning device for slaughtered pigs includes a first cleaning box, a second cleaning box, and a drying box, which are fixedly connected.

[0008] It also includes a circulating cleaning mechanism for recycling the pig washing water;

[0009] The circulating cleaning mechanism includes a second purification tank, which is fixedly installed at the bottom of the second cleaning tank. A second water pump is fixedly connected to one side of the second purification tank, and a delivery pipe is fixedly connected to one side of the second water pump. A water spray pipe is fixedly connected to one end of the delivery pipe, and the water spray pipe is fixedly installed on the outer surface of the first cleaning tank. Several cleaning brushes are rotatably installed in the inner cavities of both the first and second cleaning tanks. A filter screen is fixedly installed in the inner cavity of the second purification tank, and a clean water pipe is fixedly connected to one side of the second cleaning tank.

[0010] Preferably, a pulley is fixedly connected to the top of the cleaning brush, and two adjacent pulleys are driven by a belt. A first motor is fixedly connected to the top of the pulley, and the first motor is fixedly installed on the top of the first cleaning tank.

[0011] Preferably, a first purification box is fixedly installed at the bottom of the first cleaning box, and two conveying rollers are rotatably installed inside the first purification box. A filter conveyor belt is wound around the outer surface of the two conveying rollers. A second motor is fixedly connected to one end of one of the conveying rollers, and the second motor is fixedly installed on one side of the first purification box.

[0012] Preferably, a collection box and a scraper are fixedly installed on one side of the first purification box, and the scraper is slidably connected to the outer surface of the filter conveyor belt.

[0013] Preferably, a first water pump is fixedly connected to the bottom of the first purification tank, a hydrocyclone is fixedly connected to one side of the first water pump, a water outlet pipe is fixedly installed on the top of the hydrocyclone, one end of the water outlet pipe extends into the inner cavity of the hydrocyclone, and an output pipe is fixedly connected to the bottom of the hydrocyclone.

[0014] Preferably, four sliding rods are slidably installed on both sides of the drying oven. The four sliding rods are divided into two groups of two, and one end of the two sliding rods in the same group is fixedly connected to a push plate.

[0015] Preferably, the other ends of the two slide rods in the same group are fixedly connected to a connecting rod, and a rotating groove is provided on one side of the connecting rod, and a rotating rod is rotatably installed in the inner cavity of the rotating groove.

[0016] Preferably, mounting plates are fixedly installed on both sides of the drying oven, and a connecting plate is rotatably installed on the top of the mounting plate, the connecting plate being rotatably connected to the rotating rod.

[0017] Preferably, a third motor is fixedly mounted on the top of the mounting plate, a gear is fixedly connected to the output shaft of the third motor, and a gear ring is fixedly connected to the outer surface of the connecting plate, with the gear and the gear ring meshing with each other.

[0018] Preferably, a plurality of air ducts are fixedly installed on the outer surface of the drying chamber, and a hot air blower is fixedly installed inside the air duct.

[0019] The advantages of this invention are:

[0020] 1. The present invention uses a second water pump to draw water from the inner cavity of the second purification tank to a delivery pipe and a spray pipe. The spray pipe sprays water into the inner cavity of the first cleaning tank. The output shaft of the first motor drives the pulley to rotate, and through belt drive, all the pulleys drive the cleaning brush to rotate, thereby cleaning the surface of the slaughtered pig.

[0021] 2. This invention uses a filter conveyor belt to separate large-volume garbage from sewage. The garbage moves to the inner cavity of the collection box along the filter conveyor belt, while the sewage enters the inner cavity of the hydrocyclone separator through the first water pump. The sewage rotates and flows in the inner cavity of the hydrocyclone separator, separating the sewage from the silt and fine sand in the sewage. Finally, the sewage is discharged from the outlet pipe, and the fine sand and silt are discharged from the outlet pipe.

[0022] 3. In this invention, purified water sprayed from the purified water pipe on the second cleaning tank further cleans the slaughtered pig. The rinsed water enters the inner cavity of the second purification tank, is filtered in the second purification tank, and then flows into the inner cavity of the first cleaning tank. This allows for multiple uses of the water used to rinse the slaughtered pig, avoiding waste of water resources. Then, the slaughtered pig enters the inner cavity of the drying tank, where a third motor drives the gear and gear ring to rotate. The gear ring drives the connecting plate to rotate, and the connecting plate deflects the rotating rod. The rotating rod further moves the connecting rod, sliding rod, and push plate. The push plate impacts the slaughtered pig, and the hot air blown out by the air duct accelerates the drying of the slaughtered pig's surface. Attached Figure Description

[0031] 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.

[0032] Please see Figures 1 to 6 As shown, a pre-cleaning device for slaughtered pigs includes a first cleaning tank 1, a second cleaning tank 4, and a drying tank 5, which are fixedly connected. It also includes a circulating cleaning mechanism for recycling the pig-washing water. The circulating cleaning mechanism includes a second purification tank 33, which is fixedly installed at the bottom of the second cleaning tank 4. A second water pump 32 is fixedly connected to one side of the second purification tank 33, and a conveying pipe 31 is fixedly connected to one side of the second water pump 32. A spray pipe 3 is fixedly connected to one end of the conveying pipe 31, and the spray pipe 3 is fixedly installed on the outer surface of the first cleaning tank 1. Several cleaning brushes 11 are rotatably installed inside both the first and second cleaning tanks 1 and 4. A filter screen is fixedly installed inside the second purification tank 33, and a clean water pipe 41 is fixedly connected to one side of the second cleaning tank 4.

[0033] Existing pig cleaning equipment for slaughterhouses directly discharges the water used for cleaning the pigs after cleaning them, which easily leads to a large waste of water resources.

[0034] In use, the slaughtered pig passes through the inner cavities of the first cleaning tank 1, the second cleaning tank 4, and the drying tank 5. During the movement of the slaughtered pig, the second water pump 32 draws water from the inner cavity of the second purification tank 33, which is then sprayed out through the delivery pipe 31 and the spray pipe 3. The spray pipe 3 sprays water into the inner cavity of the first cleaning tank 1, and the cleaning brush 11 rotates to clean the slaughtered pig in the inner cavity of the first cleaning tank 1. After the initial cleaning is completed, the slaughtered pig continues to move to the inner cavity of the second cleaning tank 4 for further cleaning. Since the slaughtered pig has already been rinsed in the inner cavity of the first cleaning tank 1, the water used to clean the slaughtered pig at this time is not very dirty. After rinsing the slaughtered pig in the inner cavity of the second cleaning tank 4, the water flows into the inner cavity of the second purification tank 33. The filter screen in the inner cavity of the second purification tank 33 can retain the garbage washed off the surface of the slaughtered pig in the inner cavity of the second purification tank 33. The filtered water is drawn out by the second water pump 32, thereby realizing the recycling and filtration of the water used to clean the slaughtered pig.

[0035] Furthermore, such as Figure 2 As shown, a pulley 12 is fixedly connected to the top of the cleaning brush 11, and two adjacent pulleys 12 are driven by a belt 13. A first motor 14 is fixedly connected to the top of the pulley 12, and the first motor 14 is fixedly installed on the top of the first cleaning tank 1.

[0036] When in use, the first motor 14 drives the pulley 12 to rotate via the output shaft. Through the belt 13, all the pulleys 12 can rotate. When the pulleys 12 rotate, they will drive the cleaning brush 11 to rotate. When the slaughtered pig passes through the inner cavity of the first cleaning box 1, it will touch the cleaning brush 11. In conjunction with the water spray pipe 3, water can be sprayed onto the slaughtered pig to achieve the purpose of cleaning the slaughtered pig.

[0037] Furthermore, such as Figure 2 As shown, a first purification box 2 is fixedly installed at the bottom of the first cleaning box 1. Two conveying rollers 21 are rotatably installed inside the first purification box 2. A filter conveyor belt 22 is wound around the outer surface of the two conveying rollers 21. A second motor 23 is fixedly connected to one end of one of the conveying rollers 21. The second motor 23 is fixedly installed on one side of the first purification box 2.

[0038] A collection box 24 and a scraper 25 are fixedly installed on one side of the first purification box 2, and the scraper 25 is slidably connected to the outer surface of the filter conveyor belt 22.

[0039] In use, the wastewater flowing out of the first cleaning tank 1 enters the inner cavity of the first purification tank 2 and falls onto the filter conveyor belt 22. The surface of the filter conveyor belt 22 has several water-permeable holes, but the garbage washed off the slaughtered pigs cannot pass through the filter conveyor belt 22. The wastewater passes through the filter conveyor belt 22 and reaches the bottom of the first purification tank 2. The output shaft of the second motor 23 drives the conveyor roller 21 to rotate. The conveyor roller 21 drives the filter conveyor belt 22 to rotate, which can realize the conveying of garbage. When the garbage moves to the top of the scraper 25, the scraper 25 will scrape off the garbage on the surface of the filter conveyor belt 22. The garbage falls into the inner cavity of the collection tank 24, thereby realizing the collection of garbage.

[0040] Furthermore, such as Figure 3 As shown, a first water pump 26 is fixedly connected to the bottom of the first purification tank 2, a hydrocyclone separator 27 is fixedly connected to one side of the first water pump 26, a water outlet pipe 28 is fixedly installed on the top of the hydrocyclone separator 27, one end of the water outlet pipe 28 extends into the inner cavity of the hydrocyclone separator 27, and an output pipe 29 is fixedly connected to the bottom of the hydrocyclone separator 27.

[0041] In use, to further treat the wastewater, the wastewater at the bottom of the first purification tank 2 is pumped out by the first water pump 26 and discharged into the inner cavity of the hydrocyclone separator 27. The hydrocyclone separator 27 uses centrifugal force to separate the heavier particles such as fine sand and silt in the wastewater. Finally, the treated wastewater is discharged through the outlet pipe 28, while the fine sand and silt on the slaughtered pigs are discharged through the discharge pipe 29.

[0042] Furthermore, such as Figure 5 As shown, four sliding rods 53 are slidably installed on both sides of the drying oven 5. The four sliding rods 53 are divided into two groups of two, and one end of the two sliding rods 53 in the same group is fixedly connected to a push plate 52.

[0043] The other ends of the two slide rods 53 in the same group are fixedly connected to a connecting rod 54. A rotating groove 541 is provided on one side of the connecting rod 54, and a rotating rod 57 is rotatably installed in the inner cavity of the rotating groove 541.

[0044] When in use, the invention can drive the connecting rod 54 to move the sliding rod 53 and the push plate 52 via the rotating rod 57. After the slaughtered pig moves into the inner cavity of the drying box 5, the push plate 52 can touch the slaughtered pig. The impact of the push plate 52 on the slaughtered pig can cause the slaughtered pig to shake, which can shake off some of the water on the slaughtered pig.

[0045] Furthermore, such as Figure 5 and Figure 6 As shown, mounting plates 55 are fixedly installed on both sides of the drying oven 5, and a connecting plate 56 is rotatably installed on the top of the mounting plate 55. The connecting plate 56 is rotatably connected to the rotating rod 57.

[0046] A third motor 58 is fixedly mounted on the top of the mounting plate 55. A gear 581 is fixedly connected to the output shaft of the third motor 58. A gear ring 582 is fixedly connected to the outer surface of the connecting plate 56. The gear 581 and the gear ring 582 mesh with each other.

[0047] When in use, the third motor 58 drives the gear 581 to rotate via its output shaft. The gear 581 drives the gear ring 582 to rotate the connecting plate 56. The connecting plate 56 drives the rotating rod 57 to deflect. At the same time, the rotating rod 57 pulls the connecting rod 54 to move. The connecting rod 54 further pulls the sliding rod 53 and the push plate 52 to slide, thereby achieving the purpose of making the push plate 52 impact the slaughtered pig.

[0048] Furthermore, such as Figure 6 As shown, several air ducts 59 are fixedly installed on the outer surface of the drying box 5, and a hot air fan is fixedly installed inside the air duct 59.

[0049] When in use, the hot air blower blows hot air into the inner cavity of the drying chamber 5 through the air duct 59. The hot air passes over the surface of the slaughtered pig and can further blow away the water on the slaughtered pig, thereby achieving the purpose of quickly drying the surface of the slaughtered pig.

[0050] Working principle: First, the slaughtered pig passes through the inner cavity of the first cleaning tank 1. The second water pump 32 draws water from the inner cavity of the second purification tank 33 to the conveying pipe 31 and the spray pipe 3. The spray pipe 3 sprays water into the inner cavity of the first cleaning tank 1. The output shaft of the first motor 14 drives the pulley 12 to rotate. Through the belt 13, all the pulleys 12 drive the cleaning brush 11 to rotate, cleaning the surface of the slaughtered pig. The cleaned water enters the inner cavity of the first purification tank 2. The filter conveyor belt 22 can separate large-volume garbage from the sewage. The garbage moves to the inner cavity of the collection tank 24 with the filter conveyor belt 22. The sewage enters the inner cavity of the hydrocyclone separator 27 through the first water pump 26. The sewage rotates and flows in the inner cavity of the hydrocyclone separator 27, separating the sewage from the silt and fine sand in the sewage. Finally, the sewage is discharged from the outlet pipe 28, and the fine sand and silt are discharged from the outlet pipe 28.

[0051] After the slaughtered pig enters the inner cavity of the second cleaning chamber 4, it is further cleaned by the clean water sprayed from the clean water pipe 41. The rinsed water enters the inner cavity of the second purification chamber 33, and after being filtered in the second purification chamber 33, it flows into the inner cavity of the first cleaning chamber 1. This allows the water used to rinse the slaughtered pig to be reused multiple times, avoiding waste of water resources. Then the slaughtered pig enters the inner cavity of the drying chamber 5. The third motor 58 drives the gear 581 and the gear ring 582 to rotate. The gear ring 582 drives the connecting plate 56 to rotate. The connecting plate 56 deflects the rotating rod 57. The rotating rod 57 further moves the connecting rod 54, the sliding rod 53 and the push plate 52. The push plate 52 impacts the slaughtered pig, and the hot air blown out by the air pipe 59 can accelerate the drying of the surface of the slaughtered pig.
