Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a high-efficiency meat cleaning tank. Background Technology
[0002] The cleaning step is crucial in meat processing. Meat products, obtained after slaughter and cutting (such as pork, turtle, chicken, and duck), contain blood residue and may also contain bone fragments and other debris, necessitating cleaning. Current technology typically uses a cleaning tank to wash meat. This tank continuously draws in cleaning water, which overflows. During cleaning, the slaughtered and cut meat is placed in the tank, and impurities (including blood, bone fragments, and other debris) are transferred to the water. Some are then carried out by the overflow, while others sink and separate from the meat. After a period of time, the meat is removed. However, in actual cleaning, the meat may slowly move towards the overflow or sink, resulting in poor separation from impurities. This leads to prolonged cleaning time, wasting time and increasing water consumption. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a high-efficiency meat washing tank, which solves the problems of poor separation of meat and impurities, resulting in long washing time and increased water consumption.
[0004] According to an embodiment of this utility model, a high-efficiency meat cleaning tank includes a cleaning tank, with a feed hopper fixedly connected to one end of the cleaning tank and an overflow port provided at the other end. The cleaning tank also includes multiple upper support components arranged from one end to the other, and a lower baffle component located above the upper support components. The upper support components and the lower baffle component together form a cleaning channel, with one end of the cleaning channel close to the feed hopper. A discharge chute, close to the other end of the cleaning channel, is also fixedly connected to the cleaning tank. The lower baffle component and the upper support components are spaced apart to allow impurities to pass through. A first water inlet pipe is also fixedly connected to the cleaning tank, located below the feed hopper and directly opposite the end of the cleaning channel near the feed hopper. In this solution, the meat enters the washing tank from the feed hopper and then moves from one end of the washing channel to the other with the water flow. The water flow can pass through the upper support component and the lower baffle component. During the process, the meat is confined within the washing channel and does not move upward or downward, while impurities can sink upward or downward with the water flow and be separated from the meat. The meat is discharged from the discharge chute at the other end of the washing channel. This reduces time and water consumption, improves the overall washing efficiency, and solves the problem of poor separation of meat and impurities in the existing technology, which leads to long washing time and increased water consumption.
[0005] Furthermore, it also includes a first inclined baffle, which is inclined and its higher end is fixedly connected to the inner wall of the cleaning tank, and its lower end extends toward the end of the cleaning channel that is close to the feed hopper. A first water inlet pipe is located above the first inclined baffle, and a second water inlet pipe is also fixedly connected to the cleaning tank. The second water inlet pipe is located below the first inclined baffle and is positioned opposite the end of the cleaning channel that is close to the feed hopper.
[0006] Furthermore, a partition plate located below the cleaning channel and dividing the cleaning tank into upper and lower parts is fixedly connected inside the cleaning tank. Several filter holes are provided on the end of the partition plate away from the feed hopper. A first drain pipe and a second drain pipe located above and below the partition plate are also fixedly connected to the cleaning tank, and the first drain pipe is located below the cleaning channel.
[0007] Furthermore, the partition includes a first inclined section and a second inclined section. The first inclined section is located directly below the discharge trough and the filter holes are disposed on the first inclined section. The higher end of the second inclined section is close to the lower end of the first inclined section, and the lower end of the second inclined section is close to the first drain pipe.
[0008] Furthermore, it also includes an inclined guide plate and a second inclined baffle plate fixedly connected to the cleaning tank. The second inclined baffle plate is inclined and its higher end is close to the side of the overflow port away from the feed hopper, and its lower end is close to the end of the lower baffle assembly away from the feed hopper. The inclined guide plate is inclined and its higher end extends outside the cleaning tank, and its lower end is close to the end of the upper support assembly away from the feed hopper.
[0009] Furthermore, the discharge trough also includes a discharge hopper fixedly connected to one end of the inclined guide plate located outside the cleaning tank, and the discharge hopper has an inlet higher than the top surface of the cleaning tank and an outlet lower than the top surface of the cleaning tank.
[0010] Furthermore, a pair of horizontal pipes are fixedly connected to the inner wall of the upper end of the cleaning tank. Multiple installation pipes and an access pipe located between the two horizontal pipes are also fixedly connected. The installation pipes and access pipes are all connected to the two horizontal pipes, and multiple nozzles with downward-facing outlets are installed on all the installation pipes.
[0011] Furthermore, the two ends of the two horizontal pipes are respectively fixedly connected to the inner wall of the adjacent cleaning tank through connecting blocks.
[0012] Furthermore, the upper support assembly includes a plurality of first rollers and a plurality of second rollers arranged at equal intervals from one end of the cleaning tank to the other end. The first rollers and the second rollers are rotatable, and the second rollers are also fixedly connected with outwardly radiating blades along their axial direction.
[0013] Furthermore, the lower baffle assembly includes a plurality of third rollers equidistantly arranged from one end of the cleaning tank to the other end, and the third rollers are spaced apart from the mounting tube.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] A cleaning channel extending from the feed hopper to the discharge hopper is set up in the cleaning tank. The meat moves with the water flow and is separated from impurities in the process. This reduces the time and water consumption and improves the overall cleaning efficiency. It solves the problem of long cleaning time and increased water consumption caused by poor separation of meat and impurities in the existing technology. Attached Figure Description

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0024] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0025] In an exemplary implementation, such as Figure 1-5 As shown, this embodiment provides a high-efficiency meat cleaning tank, which includes a cleaning tank 1. The cleaning tank 1 has two opposing ends and can be a cuboid structure. A feed hopper 3 is fixedly connected above one end of the cleaning tank 1, and an overflow port 2 is provided above the other opposing end. Specifically, the overflow port 2 can be located on the side wall of the cleaning tank 1, either one on one side wall or two on both side walls. In a further embodiment, the cleaning tank 1 also includes multiple upper support components arranged from one end to the other, and a lower baffle component located above the upper support components. The upper support components and the lower baffle components together form a cleaning channel 4, and one end of the cleaning channel 4 is close to the feed hopper 3. A discharge trough 5 is also fixedly connected to the cleaning tank 1, close to the other end of the cleaning channel 4. The meat to be cleaned is fed into the cleaning tank 1 from the feed hopper 3, then enters the cleaning channel 4, and moves to the other end within the cleaning channel 4. The meat is discharged from the discharge chute 5. During the process, the lower baffle assembly and the upper support assembly are spaced apart to allow impurities to pass through, thus separating the meat from the impurities. Furthermore, a first water inlet pipe 6 is fixedly connected to the washing tank 1. The first water inlet pipe 6 is located below the feed hopper 3 and is positioned directly opposite the end of the washing channel 4 closest to the feed hopper 3. The first water inlet pipe 6 is horizontally positioned to introduce washing water into the washing tank 1. The washing water moves towards the overflow port 2 in the washing tank 1, thereby moving the meat in the washing channel 4 and separating it from the impurities during the process. Lighter components such as blood and dirt rise with the water flow and pass through the lower baffle assembly, and are guided away from the overflow port 2. Heavier components such as bone fragments and meat fragments fall downward through the upper support assembly and sink to the bottom of the washing tank 1. This reduces the time and water consumption, improves the overall washing efficiency, and solves the problem of poor separation of meat from impurities in the prior art, which leads to long washing time and increased water consumption.
[0026] like Figure 1 , 2As shown, the cleaning system also includes a first inclined baffle 7. The first inclined baffle 7 is inclined and its higher end is fixedly connected to the inner wall of the cleaning tank 1, while its lower end extends toward the end of the cleaning channel 4 that is close to the feed hopper 3. A first water inlet pipe 6 is located above the first inclined baffle 7. A second water inlet pipe 8 is also fixedly connected to the cleaning tank 1. It is located below the first inclined baffle 7 and is directly opposite the end of the cleaning channel 4 that is close to the feed hopper 3. The second water inlet pipe 8 is similar to the first water inlet pipe 6 and is used to introduce cleaning water. The cleaning water introduced by both can enter the cleaning channel 4. The difference is that the second water inlet pipe 8 is directly opposite the lower end of the first inclined baffle 7. That is, the cleaning water introduced through the second water inlet pipe 8 will come into contact with the first inclined baffle 7 and impact the lower end of the first inclined baffle 7. Then it will bend downwards at an angle, so that it can form a downward flow trend at the entrance of the cleaning channel 4. This can carry some impurities (including lighter blood stains and heavier bone and meat fragments) downwards, making the separation of impurities more efficient.
[0027] like Figure 1 , 2 As shown, a partition 9 is fixedly connected inside the cleaning tank 1, located below the cleaning channel 4 and dividing the cleaning tank 1 into upper and lower parts. Several filter holes are provided on the end of the partition 9 facing away from the feed hopper 3. These filter holes connect the upper and lower spaces of the partition 9 and also prevent heavier impurities from passing downwards through the partition 9, causing them to remain above the partition 9. Furthermore, a first drain pipe 10 and a second drain pipe 11 are fixedly connected to the cleaning tank 1, located above and below the partition 9, respectively. The first drain pipe 10 is located below the cleaning channel 4 and below the feed hopper 3, connecting to the partition 9. When the first drain pipe 10 is opened, it can drain the cleaning water containing heavier impurities. The second drain pipe 11 can be located at the bottom of the cleaning tank 1, used for subsequent drainage of the cleaning tank 1. All water is drained (valves are installed on the first drain pipe 10 and the second drain pipe 11 to control their opening and closing respectively); in a further embodiment, the partition 9 includes a first inclined section 12 and a second inclined section 13, which are respectively inclined. The first inclined section 12 is located directly below the discharge trough 5 and the filter holes are located on the first inclined section 12. At the same time, the first inclined section 12 has a greater degree of inclination, so that even if there are heavier impurities on the first inclined section 12, they can move downward more quickly and transition to the second inclined section 13. The higher end of the second inclined section 13 is close to the lower end of the first inclined section 12, and the lower end of the second inclined section 13 is close to the first drain pipe 10. This allows the heavier impurities to mainly stay on the second inclined section 13 and be drained out with the washing water more quickly when the first drain pipe 10 is opened.
[0028] like Figure 1 , 2As shown in Figure 3, the system also includes an inclined guide plate 14 and a second inclined baffle 15 fixedly connected to the washing tank 1. The second inclined baffle 15 is inclined, with its higher end close to the side of the overflow port 2 away from the feed hopper 3, and its lower end close to the end of the lower baffle assembly away from the feed hopper 3. Simultaneously, the overflow port 2 and the feed hopper 3 are both located on the same side of the second inclined baffle 15. The inclined guide plate 14 is inclined, with its higher end extending outside the washing tank 1, and its lower end close to the end of the upper support assembly away from the feed hopper 3. That is, the discharge trough 5 is formed by the two side walls of the washing tank 1, the inclined guide plate 14, and the second inclined baffle 15. After the meat passes through the washing channel 4, it enters the discharge trough 5 and is then discharged obliquely upwards through the discharge trough 5 to the outside of the washing tank 1. At the discharge trough 5, similar to existing technologies, the meat can be manually scooped up to assist in its discharge. Specifically, the second inclined baffle 15, in addition to being enclosed by the inclined guide plate 14, also... In addition to the discharge trough 5, the second inclined baffle 15 also guides the water flow and the blood mixed in the water flow at an upward angle, so that the blood can flow more smoothly with the water to the overflow port 2 and be discharged more smoothly, while also preventing blood from entering the discharge trough 5. In a further embodiment, the discharge trough 5 also includes a feeding hopper 16 fixedly connected to one end of the inclined guide plate 14 located outside the washing tank 1. The feeding hopper 16 has an inlet higher than the top surface of the washing tank 1 and an outlet lower than the top surface of the washing tank 1. That is, the meat is scooped up at an upward angle to the inlet and then falls downward and is discharged through the outlet. It should be noted that the higher end of the inclined guide plate 14 in this embodiment is higher than the lower edge of the overflow port 2. In this way, the washing water will not be higher than the inclined guide plate 14, so it can be discharged smoothly through the overflow port 2. That is to say, the water flow in the discharge trough 5 is poor, and no more blood and impurities will be brought in, thus ensuring a better cleaning effect for the meat.
[0029] like Figure 1 , 2As shown in Figures 4 and 5, a pair of horizontal pipes 17 are fixedly connected to the inner wall of the upper end of the cleaning tank 1. The ends of the two horizontal pipes 17 are respectively fixedly connected to the inner wall of the adjacent cleaning tank 1 via connecting blocks 18, so that the horizontal pipes 17 can be stably placed in the cleaning tank 1. At the same time, the two horizontal pipes 17 extend along the length of the cleaning tank 1. Furthermore, multiple mounting pipes 19 and an access pipe 20 located between the two horizontal pipes 17 are fixedly connected. The mounting pipes 19 and the access pipe 20 are both connected to the two horizontal pipes 17, and multiple nozzles 21 with downward-facing outlets are installed on all mounting pipes 19. The access pipe 20 can also be fixedly connected to an inlet pipe 22, through which high-pressure water (or...) can be introduced. High-pressure air is introduced, and high-pressure water, which has a higher pressure than cleaning water, is sprayed downwards through the inlet pipe 20, horizontal pipe 17, installation pipe 19, and nozzle. The high-pressure water jet flows downwards through the lower baffle assembly, rinsing the meat products in the cleaning channel 4. This allows blood, bone fragments, meat scraps, and other residues to be separated from the meat products more efficiently. Lighter impurities can be flushed upwards with the water flow and discharged through the overflow port 2 in subsequent processes, while heavier impurities can sink to the bottom more quickly for separation, ultimately improving cleaning efficiency. In a further embodiment, the upper support assembly includes multiple first rollers 23 and multiple second rollers 24 arranged at equal intervals from one end of the cleaning tank 1 to the other. The first rollers 23 and second rollers 24 are... The first roller 23 and the second roller 24 are configured with rotating blades 25 that are fixedly connected to the second roller 24 along its axial direction. The first roller 23 and the second roller 24 have a small gap between them to prevent the meat from moving downwards, but allow impurities to pass through. Simultaneously, the meat is moved by the water flow introduced through the first water inlet pipe 6 and the second water inlet pipe 8. Furthermore, the blades 25 on the second roller 24 can assist the second roller 24 in rotating under the impact of the water flow, further assisting the movement of the meat. Meanwhile, the first roller 23, which does not have blades 25, can also rotate during the movement of the meat and under the influence of the water flow, thus assisting the meat in moving within the washing channel 4. Note: It is worth noting that the water flow rate sprayed through the nozzle is less than the amount introduced by the first water inlet pipe 6 and the second water inlet pipe 8. The movement of the meat products mainly relies on the cleaning water introduced by the first water inlet pipe 6 and the second water inlet pipe 8. Similar to the upper support assembly, the lower baffle assembly includes multiple third rollers 26 arranged equidistantly from one end of the cleaning tank 1 to the other end. The third rollers 26 are spaced apart from the mounting pipe 19 so that the nozzles are positioned between the third rollers 26 to avoid obstruction of the sprayed water flow. The third rollers 26 can also rotate during the movement of the meat products, thereby playing an auxiliary movement role similar to that of the first roller 23. Alternatively, the third rollers 26 can be set to not rotate, mainly to prevent the meat products from moving upward.More specifically, the blades 25 can be curved, and the first roller 23 closest to the first inclined baffle 7 is located diagonally below the lower end of the first inclined baffle 7. Simultaneously, the subsequent first roller 23 and second roller 24 are arranged at the same horizontal level. This allows the cleaning water introduced by the first water inlet pipe 6 and the second water inlet pipe 8 to move laterally under the auxiliary guidance of the first inclined baffle 7, thus pushing the blades 25 and assisting the rotation of the second roller 24.
[0030] like Figure 1 , 2 As shown, in a further embodiment, multiple fourth rollers 27 are arranged at an angle between the third roller 26 closest to the feed hopper 3 and the feed hopper 3. Similar to the third roller 26, the fourth rollers 27 can also rotate under the push of the water flow and the meat, thereby assisting the movement of the meat. In particular, the fourth rollers 27, the first inclined baffle 7, and the pair of inner walls of the washing tank 1 form an inclined connecting channel 28 connecting the feed hopper 3 and the washing channel 4. The washing water introduced by the first water inlet pipe 6 can pass through the fourth rollers 27, and the distance between the fourth rollers 27 is also relatively small to confine the meat within the connecting channel 28, so that it can smoothly enter the washing channel 4 from the feed hopper 3. In the connecting channel 28, the meat is subjected to downward gravity and falls downward, moving obliquely downward under the inclined guidance of the first inclined baffle 7. At the same time, the washing water introduced by the first water inlet pipe 6 is introduced laterally to rinse the meat at a relatively inclined angle, and also assists the meat to move faster (due to gravity). The fourth roller 27 blocks the flow, allowing the meat to move diagonally downwards into the cleaning channel 4 more quickly under the combined impact of the washing water and gravity. During this process, the washing water can more efficiently flush away the blood and dirt, thus improving the cleaning efficiency. In another embodiment, the first water inlet pipe 6 can also be inclined, similar to the first inclined baffle 7, with its lower end connected to the cleaning tank 1, so that the washing water is introduced diagonally downwards. This makes the impact direction of the washing water roughly the same as the movement direction of the meat in the connecting channel 28, allowing the meat to enter the cleaning channel 4 relatively quickly. In the cleaning channel 4, the washing water introduced by the first water inlet pipe 6 and the second water inlet pipe 8 moves diagonally downwards for a certain distance, and then moves upwards in an arc towards the overflow outlet, thus pushing the meat in the cleaning channel 4. In other words, the overall flow direction of the washing water in the cleaning tank 1 is from one end to the other, ensuring that the meat can pass through the cleaning channel 4 with the water flow.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
