Description

Technical Field

[0001] This application relates to the field of pig slaughtering technology, and in particular to a high-pressure cleaning machine for pigs. Background Technology

[0002] In the pig slaughtering and processing industry, cleaning the blood, impurities, and other contaminants adhering to the surface of the pig carcass after slaughter is crucial to the hygiene and quality of pork products and is a preliminary step in subsequent processing.

[0003] Currently, modern slaughtering and processing pursues an efficient and continuous operating mode, requiring close connection between each link to maximize production efficiency. However, most pig cleaning equipment does not match the feeding and discharging methods of the slaughtering production line. The cleaning equipment is not convenient to use with the overhead chain conveyor line commonly used in slaughtering, resulting in poor connection between the pig cleaning process and the preceding and following processes, which can easily lead to waiting or congestion and affect the smoothness of the entire production line.

[0004] In addition, most pig cleaning equipment uses a single-direction or fixed-position rinsing method, which cannot clean all parts of the pig carcass evenly and thoroughly, thus reducing the cleaning effect.

[0005] To address the aforementioned problems, a high-pressure cleaning machine for pigs has been designed. Utility Model Content

[0006] This application provides a high-pressure cleaning machine for pigs to solve the problem in the related art where the feeding and discharging methods of the cleaning equipment do not match the conveying rhythm of the slaughtering production line, resulting in poor connection between the cleaning process and the preceding and following processes, which affects work efficiency.

[0007] Firstly, a high-pressure cleaning machine for pigs is provided, comprising:

[0008] A suspended chain conveyor line having multiple hooks for suspending and conveying pig carcasses, and a cleaning chamber arranged along the conveying direction of the hooks, characterized in that a through hole for the hooks to enter is provided above the cleaning chamber;

[0009] The cleaning chamber has a cavity for cleaning pig carcasses, and an inlet and an outlet are provided opposite to each other on the cavity along the conveying direction of the hook;

[0010] The cavity is equipped with a cleaning mechanism, which includes a rectangular rinsing unit arranged in the cavity and a lifting component connected to the rectangular rinsing unit. The rectangular rinsing unit is used to rinsing the pig carcass under high pressure, and the lifting component is used to drive the rectangular rinsing unit to move up and down.

[0011] A liquid supply mechanism for supplying liquid to the rectangular flushing unit.

[0012] In some embodiments, the entrance and exit of the chamber are both hinged with sealing doors.

[0013] In some embodiments, the cleaning chamber has two baffles positioned opposite each other above the through holes.

[0014] In some embodiments, the rectangular flushing unit includes a rectangular pipe with a plurality of high-pressure nozzles arranged in a rectangular pattern on the inner side of the rectangular pipe. The spray nozzles of the high-pressure nozzles are inclined upwards, and a connector is provided on the rectangular pipe.

[0015] In some embodiments, the lifting component includes an electric push rod disposed opposite to the cleaning chamber and two fixed collars disposed opposite to the rectangular pipe, wherein the bottom end of the piston rod of the electric push rod is connected to the fixed collars.

[0016] In some embodiments, the liquid supply mechanism includes a liquid storage tank, a pump body disposed on the liquid storage tank, the inlet of the pump body being connected to the liquid storage tank, and the outlet of the pump body being provided with a delivery pipe, the delivery pipe and the connector being connected by a flexible hose.

[0017] In some embodiments, the bottom of the cleaning chamber is provided with a collection hopper for recycling waste liquid, and the top of the collection hopper is open and communicates with the chamber;

[0018] The collecting hopper is a cone-shaped hopper that is wider at the top and narrower at the bottom, and the bottom of the collecting hopper is connected to a drain pipe.

[0019] This application provides a high-pressure cleaning machine for pigs. Through its cleaning chamber, through-holes, cavity, inlet, and outlet, it can be integrated with the overhead chain conveyor line on the pig slaughtering line. This makes it highly compatible with the overhead chain conveyor method commonly used in modern slaughtering production lines, allowing pig carcasses to smoothly transition from the slaughtering stage to the cleaning stage and then into the subsequent processing stage. The entire process requires no manual intervention for material transfer, achieving seamless connection between various processes, improving the continuity and smoothness of production, and enhancing overall production efficiency.

[0020] By using the rectangular rinsing unit, lifting components, and liquid supply mechanism in combination, the pig carcass can be rinsed from different heights and multiple angles, ensuring that all parts of the pig carcass are cleaned evenly, effectively avoiding the occurrence of cleaning dead corners, and greatly improving the thoroughness and uniformity of cleaning.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] This application provides a high-pressure cleaning machine for pigs, which can solve the problem in the related art where the feeding and discharging methods of the cleaning equipment do not match the conveying rhythm of the slaughtering production line, resulting in poor connection between the cleaning process and the preceding and following processes, thus affecting work efficiency.

[0029] Please see Figures 1-3A high-pressure cleaning machine for pigs includes: a suspended chain conveyor 1 with multiple hooks 2 for suspending and conveying pig carcasses; a cleaning chamber 3 arranged along the conveying direction of the hooks 2; a through hole 34 for the hooks 2 to enter the cleaning chamber 3; a cavity 31 for cleaning the pig carcasses inside the cleaning chamber 3; an inlet 32 ​​and an outlet 33 opposite to each other on the cavity 31 along the conveying direction of the hooks 2; a cleaning mechanism 4 arranged inside the cavity 31; the cleaning mechanism 4 includes a rectangular rinsing unit 41 arranged in the cavity 31 and a lifting component 42 connected to the rectangular rinsing unit 41; the rectangular rinsing unit is used for high-pressure rinsing of the pig carcasses; the lifting component 42 is used to drive the rectangular rinsing unit 41 to move up and down; and a liquid supply mechanism 5 for supplying liquid to the rectangular rinsing unit 41.

[0030] After the pigs are slaughtered, the pig carcasses are hung one by one on hooks 2 on the overhead conveyor 1. The overhead conveyor 1 then starts to run at a preset speed and direction, moving the hooks 2 and the pig carcasses on them.

[0031] When hook 2 moves the pig carcass above the cleaning chamber 3, hook 2 enters the internal chamber 31 of the cleaning chamber through the through hole 34 on the top of the cleaning chamber 3. The pig carcass enters from the entrance 32 of the chamber 31 and the cleaning process begins.

[0032] The liquid supply mechanism 5 is activated, delivering cleaning water at a certain pressure to the rectangular rinsing unit 41. The rectangular rinsing unit 41 sprays high-pressure water jets onto the pig carcass. At the same time, the lifting component 42 starts working, driving the rectangular rinsing unit 41 to move up and down within the chamber 31. During the lifting process, the rectangular rinsing unit 41 performs all-round high-pressure rinsing of the pig carcass from different heights, ensuring that all parts of the pig carcass, including the top, sides, bottom, and some hidden parts, are evenly and thoroughly rinsed, effectively removing surface-adhered blood, impurities, etc.

[0033] After the pig carcass is cleaned in chamber 31, it leaves the cleaning chamber 3 through outlet 33 of chamber 31 as hook 2 continues to move, and enters the subsequent processing steps for cutting.

[0034] The through-hole 34 on the cleaning chamber 3, the inlet 32 ​​and the outlet 33 on the chamber 31 can be used in conjunction with the overhead chain conveyor 1 and hook 2 on the pig slaughtering line, thus highly adapting to the overhead chain conveyor commonly used in modern slaughtering production lines. This allows pig carcasses to smoothly transition from the slaughtering stage to the cleaning stage and then into the subsequent processing stage. The entire process does not require manual intervention for material transfer, achieving seamless connection between various processes, greatly improving the continuity and smoothness of production, and effectively enhancing overall production efficiency.

[0035] By using the rectangular rinsing unit 41, the lifting component 42 and the liquid supply mechanism 5 together, the pig carcass can be rinsed from different heights and multiple angles, ensuring that all parts of the pig carcass are cleaned evenly, effectively avoiding the occurrence of cleaning dead corners, and greatly improving the thoroughness and uniformity of cleaning.

[0036] The high-pressure water flow provided by the liquid supply mechanism 5 can generate a powerful impact force, quickly washing away impurities on the surface of the pig carcass.

[0037] The overhead chain conveyor line 1 in this embodiment is an automated conveying equipment widely used in the pig slaughtering and processing industry for the continuous and efficient transport of pig carcasses. It mainly consists of a chain, track, drive unit, tensioning device, hooks, and related support structures. During operation, after starting the drive unit, the motor drives the reducer, which transmits power to the chain through a sprocket, causing the chain to circulate on the track. The hooks 2 move along with the chain. The operator suspends the slaughtered pig carcasses on the hooks, and the carcasses move along the conveyor line, passing through each processing station in sequence. During the conveying process, the tensioning device maintains appropriate tension on the chain to ensure stable operation of the conveyor line. This is existing technology and will not be described in detail here.

[0038] like Figure 1 and Figure 2 As shown, it should be noted that in this embodiment, both the inlet 32 ​​and the outlet 33 of the chamber 31 are hinged with sealing doors 6.

[0039] The sealing door 6 is installed at the entrance 32 and the exit 33 of the chamber 31 by hinges. The hinges serve as connecting parts, allowing the sealing door 6 to rotate around a fixed axis, thereby realizing the opening and closing action.

[0040] The dimensions of the sealing door 6 are adapted to the dimensions of the inlet 32 ​​and the outlet 33 respectively, so as to ensure that it can completely cover the inlet or outlet when closed, achieving a good sealing effect.

[0041] In actual use, the sealing door 6 is opened before the pig carcass enters the cleaning chamber 3, and the sealing door 6 is closed after the pig carcass enters the cleaning chamber 3 to carry out the cleaning operation, so as to avoid the splashing of sewage after cleaning.

[0042] As shown in the figure, in this embodiment, the cleaning chamber 3 is further provided with two baffles 7 located above the through holes 34.

[0043] Two baffles 7 are symmetrically arranged on the cleaning chamber 3 and are directly above the through hole 34. The through hole 34 is the channel for the hook 2 of the suspended chain conveyor line 1 to enter and exit. The baffles 7 are located on both sides above the through hole 34 and can cover a certain area above the through hole 34, which can block liquids that may splash during the cleaning process.

[0044] like Figure 3 and Figure 4 As shown, in one embodiment, the rectangular rinsing unit 41 includes a rectangular pipe 411, and a plurality of high-pressure nozzles 412 arranged in a rectangular pattern are provided on the inner side of the rectangular pipe 411. The spray nozzles of the high-pressure nozzles 412 are inclined upward, and a connector 413 is provided on the rectangular pipe 411.

[0045] When cleaning water is delivered into the rectangular pipe 411 through the connector 413, the water flows within the rectangular pipe 411 and is evenly distributed to each high-pressure nozzle 412. Since the spray nozzles of the high-pressure nozzles 412 are tilted upwards, the high-pressure water is sprayed upwards from the spray nozzles, forming multiple high-pressure water jets. The suspended chain conveyor 1 slowly passes through the cleaning chamber 3 with the hooks 2 on which the pig carcasses are suspended. When the pig carcasses enter the cleaning range of the rectangular rinsing unit 41, these high-pressure water jets will impact and clean the sides of the pig carcasses, washing away the dirt, blood and other impurities attached to the pig carcasses, thereby achieving the purpose of cleaning.

[0046] like Figure 3 and Figure 4 As shown, in one embodiment, the lifting component 42 includes an electric push rod 421 disposed opposite to the cleaning chamber 3, and two fixing collars 422 disposed opposite to the rectangular pipe 411, wherein the bottom end of the piston rod of the electric push rod 421 is connected to the fixing collars 422.

[0047] Before the pig carcass enters the chamber 31, when the pig carcass is about to leave the chamber 31, the piston rod of the electric push rod 421 is in the extended state, and the rectangular pipe 411 is located at the bottom of the cleaning chamber 3 to avoid interfering with the entry and exit of the pig carcass.

[0048] The electric linear actuator 421 mainly consists of a motor, reduction gear, screw, nut, guide sleeve, push rod, slide, spring, housing, turbine, and micro-switch. The motor drives the screw to rotate through the reduction gear, and the nut moves linearly on the screw, thereby driving the push rod to extend and retract, realizing the extension and retraction of the piston rod.

[0049] When cleaning is required, the control system issues a command, and the piston rod of the electric push rod 421 retracts. The bottom end of the piston rod is connected to the fixed collar 422. The retraction of the piston rod will drive the rectangular pipe 411 to move upward, thus cleaning the pig carcass.

[0050] After the cleaning process is completed, the piston rod extends. When the piston rod of the electric push rod 421 is fully extended, the rectangular pipe 411 is located at the bottom of the cleaning chamber 3, which will not interfere with the entry and exit of the pig carcass.

[0051] like Figure 1 and Figure 2 As shown, in one embodiment, the liquid supply mechanism 5 includes a liquid storage tank 51, a pump body 52 disposed on the liquid storage tank 51, the inlet of the pump body 52 communicating with the liquid storage tank 51, and the outlet of the pump body 52 being provided with a delivery pipe 53. The delivery pipe 53 and the connector 413 are connected by a flexible hose 54. The liquid storage tank 51 is provided with a liquid injection port.

[0052] When cleaning is required, an appropriate amount of cleaning liquid is first injected into the storage tank 51 through the injection port. Then, the pump body 52 is started. The pump body 52 starts working, and its inlet draws liquid from the storage tank 51. After being pressurized by the pump body 52, the liquid is delivered from the outlet through the delivery pipe 53. The liquid in the delivery pipe 53 is then delivered through the hose 54 to the connector 413 of the rectangular flushing unit 41, and then enters the rectangular pipe 411. Finally, it is sprayed out through the high-pressure nozzle 412 to clean the pig carcass.

[0053] like Figure 1 and Figure 2 As shown, it should be further explained that the bottom of the cleaning chamber 3 is provided with a collection hopper 8 for recycling waste liquid. The top of the collection hopper 8 is open and communicates with the chamber 31. The collection hopper 8 is a conical hopper that is wider at the top and narrower at the bottom. The bottom of the collection hopper 8 is connected to a drain pipe.

[0054] The collection hopper 8 is a conical hopper, wider at the top and narrower at the bottom. The wider top section maximizes coverage of the effective area at the bottom of the washing chamber 3, ensuring that all waste liquid rinsed from the pig carcass flows smoothly into the collection hopper 8. The narrower bottom section facilitates the collection and aggregation of the waste liquid. The collection hopper 8 is made of stainless steel, offering excellent corrosion resistance. Its smooth surface does not easily attract dirt, facilitating daily cleaning and maintenance, and meeting the hygiene requirements of the food processing industry.

[0055] During the cleaning process, when the high-pressure nozzle 412 sprays cleaning liquid onto the pig carcass, the waste liquid will flow down the surface of the pig carcass and eventually drip into the bottom of the cleaning chamber 3. The waste liquid will then flow into the collection hopper 8, achieving the initial collection of waste liquid.

[0056] Once a certain amount of waste liquid has accumulated in the collection tank 8, the waste liquid will be discharged through the drain pipe, which will then send the waste liquid into the subsequent waste liquid treatment system.
