Description

Technical Field

[0001] This utility model relates to the field of pig slaughtering technology, and in particular to a hot and cold water circulation tank. Background Technology

[0002] The slaughtering and processing of live pigs mainly includes the following steps: pre-slaughter preparation, showering, stunning, bleeding, hair removal or skinning, evisceration, removal of internal organs, inspection, trimming, grading, stamping, weighing, etc.; among which, scalding of live pigs is done by manually placing the live pigs into a scalding pool, which requires the use of a corresponding scalding pool.

[0003] Currently, in pig carcass processing, scalding and cooling / washing processes are typically performed in separate equipment.

[0029] This utility model proposes a hot and cold water circulation tank 1000.

[0030] Please see Figure 1 and Figure 2In one embodiment of this utility model, the hot and cold water circulation pool 1000 includes a scalding pool 1, a hair removal assembly, and a temperature control assembly. The scalding pool 1 is used to hold water for hair removal of pig carcasses. The hair removal assembly includes a lifting drive 21, a hair removal frame 22, and a hair removal device 23. The lifting drive 21 is located in the scalding pool 1, and the hair removal frame 22 is connected to the output end of the lifting drive 21. The lifting drive 21 drives the hair removal frame 22 to move up or down to approach or move away from the scalding pool 1. The hair removal frame 22 is used to support the pig carcass. The hair removal device 23 is located in the hair removal frame 22 and is used to remove hair from the pig carcass. The temperature control assembly includes a heater 31, a cooler 32, and a temperature sensor 33. The temperature sensor 33 is located in the scalding pool 1. The heater 31 is located in the scalding pool 1 and is used to heat the water in the scalding pool 1. The cooler 32 is located in the scalding pool 1 and is used to cool the water in the scalding pool 1. The temperature sensor 33 is electrically connected to the heater 31 and the cooler 32, respectively.

[0031] In the technical solution of this utility model, before dehairing, the water in the scalding tank 1 is heated by the heater 31. After being heated to the specified temperature, the lifting drive 21 drives the dehairing frame 22 to descend into the scalding tank 1 to scald the pig carcass. After scalding for a certain period of time, the lifting drive 21 drives the dehairing frame 22 to rise above the water surface, and then the dehairing device 23 is activated to dehair the pig carcass. At the same time, the cooler 32 is activated to cool the water in the scalding tank 1. After the pig carcass is dehaired, the lifting drive 21 drives the dehairing frame 22 to descend into the scalding tank 1, and the water in the tank is used to preliminarily clean the hair removed from the pig carcass, completing the preliminary dehairing work of the pig carcass. The scalding, dehairing, and cooling cleaning of the pig carcass are completed in the same tank, avoiding the waste of water resources during the transfer of the pig carcass to different equipment, thereby reducing the water consumption during the pig carcass processing.

[0032] Specifically, the hair removal device 23 can be a device that uses blades on an elastic element to shave the hair off the pig carcass, or it can use a hair removal roller for hair removal; there are no limitations on this. Accordingly, for all-around hair removal, the hair removal device 23 may also include a moving device to move the elastic element or the hair removal roller.

[0033] In one embodiment of this utility model, the bottom of the scalding tank 1 is provided with a water outlet 1a, and the hot and cold water circulation tank 1000 also includes a cover plate 4, which is connected to the scalding tank 1 and is used to cover the water outlet 1a. The water outlet 1a facilitates the discharge and replacement of water in the scalding tank 1, and the design of the cover plate 4 can effectively prevent impurities from entering the water outlet 1a, ensuring the unobstructed flow of the water outlet 1a.

[0034] Specifically, the cover plate 4 can be connected to the scalding tank 1 via hinges or slide rails, so as to open or close as needed. As a preferred embodiment, the cover plate 4 can be made of corrosion-resistant material to extend its service life.

[0035] In one embodiment of this utility model, the hot and cold water circulation tank 1000 further includes a treatment tank 5, a connecting pipe, and a water pump 6. The treatment tank 5 has an inlet 5a, and an outlet 1a is connected to the inlet 5a via a connecting pipe, with the outlet 1a positioned higher than the opening of the treatment tank 5. The water pump 6 is located in the treatment tank 5 and is used to transport water from the treatment tank 5 to the scalding tank 1. The treatment tank 5 receives water discharged from the scalding tank 1 and is connected to the outlet 1a of the scalding tank 1 via a connecting pipe. The outlet 1a is positioned higher than the opening of the treatment tank 5, allowing water to flow naturally into the treatment tank 5 by gravity. The water pump 6 is installed inside the treatment tank 5 and is used to pump water from the treatment tank 5 back into the scalding tank 1, thereby achieving water recycling and further avoiding water waste.

[0036] Specifically, the design of the treatment tank 5 allows for the effective collection and treatment of water from the scalding tank 1 after use, avoiding resource waste caused by direct discharge. Through the connecting pipes, water can flow naturally from the scalding tank 1 into the treatment tank 5 without the need for additional power equipment. The installation of the water pump 6 further improves the water circulation efficiency, ensuring that the scalding tank 1 can continuously obtain the required water volume, thereby improving the overall system operating efficiency.

[0037] In one embodiment of this utility model, the hot and cold water circulation tank 1000 further includes a filtration device, which is disposed inside the connecting pipe and is used to filter the water flowing from the scalding tank 1 to the treatment tank 5. When the water in the scalding tank 1 flows to the treatment tank 5 through the connecting pipe, the filtration device intercepts and filters the water flow to ensure that the water entering the treatment tank 5 is clean. The water in the treatment tank 5 can be pumped back to the scalding tank 1 by the water pump 6 to realize water recycling and reduce water waste. By setting up the filtration device, the problem of many impurities in the water flow between the scalding tank 1 and the treatment tank 5 is effectively solved, and the accumulation of impurities in the treatment tank 5 is avoided, thereby improving the cleanliness of the water.

[0038] Specifically, the filtration device can be a multi-layer filter screen, and the pore size of the filter screen can be selected according to actual needs to ensure effective filtration of impurities in the water; the filtration device can also be an activated carbon layer, used to adsorb odors and harmful substances in the water; the filtration device can also be a combination of multi-layer filter screen and activated carbon layer.

[0039] In one embodiment of this utility model, the peripheral wall of the dehairing frame 22 has four inclined surfaces 22a, each inclined surface 22a being arranged in pairs opposite to each other, and the bottom end of each inclined surface 22a extending to the bottom wall of the dehairing frame 22; the dehairing frame 22 has a dehairing station 22b located on the bottom wall of the dehairing frame 22. The design of the four inclined surfaces 22a of the dehairing frame 22 helps to better fix the position of the pig carcass during the dehairing process, avoiding slippage or displacement during the dehairing process; the bottom end of the inclined surface 22a extending to the bottom wall of the dehairing frame 22 ensures that the pig carcass can fully contact the dehairing device 23 during the dehairing process, improving the dehairing efficiency; the dehairing station 22b being located on the bottom wall of the dehairing frame 22 allows the pig carcass to be stably placed inside the dehairing frame 22 during the dehairing process, further ensuring the dehairing effect. The angle of the inclined surfaces 22a can be adjusted according to actual needs to adapt to pig carcasses of different sizes and shapes.

[0040] In one embodiment of this utility model, the hair removal assembly further includes a hair removal filter 24, which is disposed on the bottom wall of the hair removal frame 22. The hair removal filter 24 can effectively solve the problem of pig hair and impurities entering the water in the scalding tank 1 during the hair removal process, thereby avoiding water pollution and increased difficulty in subsequent treatment; by filtering pig hair and impurities, the hair removal filter 24 can keep the water in the scalding tank 1 clean, reduce the frequency of subsequent cleaning and water changes, and improve work efficiency.

[0041] Specifically, the hair removal filter 24 can be fixed to the bottom wall of the hair removal frame 22, or it can be designed to be detachable for easy cleaning and replacement.

[0042] In one embodiment of this utility model, the hair removal assembly further includes a nozzle 25 and a water pump 26. The nozzle 25 is disposed on the hair removal frame 22 and faces the hair removal station 22b; the water pump 26 is disposed in the scalding tank 1 and is connected to the nozzle 25 by a pipe. By adding the nozzle 25 and the water pump 26, the hair removed from the pig carcass can be further washed away by the impact force of the water flow during the hair removal process, thereby improving the cleanliness of the pig carcass after hair removal. The number and arrangement of the nozzles 25 can be adjusted according to the size of the hair removal frame 22 and the hair removal requirements.

[0043] In one embodiment of this utility model, the hair removal assembly further includes an opening and closing door, which comprises two door bodies 271. The two door bodies 271 are rotatably connected to the top ends of opposite two walls of the hair removal frame 22. One end of one door body 271, away from the hair removal frame 22, is movably connected to the other end of the other door body 271, also away from the hair removal frame 22. The two door bodies 271 are rotatably connected on opposite sides of the hair removal frame 22, with the rotation axis of each door body 271 located at the top end of the hair removal frame 22. The other ends of the door bodies 271 are movably connected to each other, allowing both door bodies 271 to open or close simultaneously. The design of the opening and closing door allows the hair removal frame 22 to be easily opened when needed for the insertion or removal of the pig carcass, and can be closed during the hair removal process to prevent the pig carcass from accidentally slipping out.

[0044] Specifically, the two door bodies 271 of the opening and closing door can be installed on the top of the hair removal frame 22 by hinges or other rotating connectors, and the other end of the door body 271 can be connected to each other by pins, buckles or other movable connectors.

[0045] In one embodiment of this utility model, the hair removal assembly further includes a rotation drive 28, which is connected to the output end of the lifting drive 21. The hair removal frame 22 is connected to the output end of the rotation drive 28, and the rotation drive 28 drives the hair removal frame 22 to rotate. The rotation of the hair removal frame 22 allows for a thorough rinsing of the pig carcass after hair removal, thereby further improving the cleaning effect of the pig carcass. The rotation drive 28 can be a motor, a hydraulic motor, or other device capable of providing rotational power. The rotation drive 28 is connected to the hair removal frame 22 via a coupling or direct connection, thereby driving the hair removal frame 22 to rotate around its axis.

[0046] It is understood that the lifting drive component 21 can be a hydraulic cylinder, a pneumatic cylinder, or a drive motor. In one embodiment of this utility model, the lifting drive component 21 is a hydraulic cylinder. As a common hydraulic actuator, the hydraulic cylinder works by using the pressure of hydraulic oil to push the piston rod to move linearly, thereby achieving the lifting function. The hydraulic cylinder has the characteristics of simple structure, large output force, and smooth movement, which can meet the lifting requirements of the hair removal frame 22 in the scalding tank 1. Specifically, the cylinder body of the hydraulic cylinder is fixed on the scalding tank 1, and the piston rod is connected to the hair removal frame 22. By controlling the inflow and outflow of hydraulic oil, the lifting speed and position of the hair removal frame 22 can be precisely controlled, ensuring that the hair removal frame 22 can smoothly approach or move away from the scalding tank 1. At the same time, the hydraulic cylinder will not short-circuit due to the internal components coming into contact with water, thus ensuring the operational stability of the lifting drive component 21. In summary, the lifting drive component 21 is preferably a hydraulic cylinder.

[0047] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
