Description

Technical Field

[0001] The present application relates to the technical field of abalone freshness preservation, and in particular to a cooling device for ultra-low temperature abalone freshness preservation. Background Art

[0002] At present, on the abalone processing production line, the raw abalone needs to be processed through ultra-low temperature freezing technology to lock in freshness after cleaning, steaming and other processes.

[0003] In the prior art, the ultra-low temperature cooling process for abalone after steaming is generally carried out by the following steps: first, the steamed abalone is conveyed into an ice water pool for rapid cooling via a conveyor; after the abalone is pre-cooled in the ice water, it is then ultra-low temperature quick-frozen using liquid nitrogen quick-freezing technology to lock in the freshness of the abalone.

[0004] However, existing technologies have the following drawbacks: the ice pools used in the aforementioned freshness-locking process are generally open-topped. This structure causes a large amount of cold energy (cold air) within the pool to escape through the openings, causing the ice in the pool to melt faster and shortening the time the pool can maintain an effective low-temperature environment. Summary of the Invention

[0005] In order to increase the time that the ice water pool maintains an effective low-temperature environment, the present application provides an ultra-low-temperature abalone freshness-preserving cooling device.

[0006] The present application provides an ultra-low temperature abalone freshness-preserving cooling device, which adopts the following technical solutions: A cooling device for ultra-low temperature abalone freshness preservation, comprising: an ice water pool, which is a rectangular frame structure extending in one direction, wherein a conveyor belt is provided in the ice water pool for conveying materials along the extension direction of the ice water pool; a heat preservation cover, which is arranged at an open position above the ice water pool, and comprises two top plates and two parallel side plates, wherein the top plate is connected to a material conveying pipe extending toward the ice water pool; two ice frames for placing ice cubes, comprising a bottom plate, two parallel side baffles and an end plate arranged at the end of the bottom plate, wherein water permeable holes are evenly distributed on the bottom plate, and a rotating shaft is fixed to the middle part of the two side baffles; wherein a circular track is fixed on the side close to each other of the two side plates, and the circular track comprises two vertical tracks and two horizontal tracks, and the vertical tracks are connected to the two horizontal tracks. An arc transition connection is formed between the vertical track and the horizontal track; two connecting seats that move along the circular track are installed on the circular track, and a driving assembly is provided on the side plate for driving the two connecting seats to move synchronously in the same direction, and the initial positions of the two connecting seats are respectively located in the middle of the two vertical tracks; the two ice placing frames are rotatably connected to the connecting seats on the circular track through rotating shafts, and the side plates are also provided with limiting members that keep the ice placing frames in a horizontal state when the ice placing frames move; when the two connecting seats are in the initial position, the two ice placing frames are connected end to end and are at the same water level height of the ice water pool; when a connecting seat moves to the upper end of the horizontal track, the ice placing frame is close to the outlet of the feed pipe.

[0007] By adopting the above technical solution, the insulation cover is arranged at an open position above the ice water pool, which effectively reduces the escape of low-temperature cold (cold air) in the ice water pool, reduces the melting speed of ice cubes, prolongs the time that the ice water pool maintains an effective low-temperature environment, and ensures the pre-cooling and cooling effect of abalone; the feeding pipe is connected to the top plate and extends toward the ice water pool, which is convenient for conveying ice cubes to the ice frame in the ice water pool for replenishment of ice cubes; the structural design of the ice frame and the connection method with the circular track and the connecting seat are such that the connecting seat is moved along the circular track by the driving component to drive the ice frame to move, which can facilitate the replenishment of ice cubes, that is, when the front end ice frame moves backward in the transverse track at the upper end during the process of moving upward, backward and downward to the rear end, the ice cubes discharged by the feeding pipe can be evenly replenished to maintain the low temperature of the ice water pool. At the same time, the ice frame is rotatably connected to the connecting seat through the rotating shaft, and is kept horizontally in cooperation with the limiter to ensure the stable placement of ice cubes.

[0008] Optionally, both the side panels and the end panels are slidably connected with extended floating panels; when the connecting seat moves toward the lower transverse track, the extended floating panels slide out from the side panels and the end panels to prevent floating ice from escaping from the ice storage frame.

[0009] By adopting the above technical solution, when the connecting seat moves toward the lower horizontal track, the extended floating plate slides out from the side plate and the end plate, preventing the floating ice from escaping from the ice frame, ensuring the stability of the amount of ice in the ice frame and maintaining the low temperature environment of the ice water pool.

[0010] Optionally, the limiting member includes a rectangular limiting frame fixed to the inner wall of the side panel, the circular track is located in the rectangular limiting frame, and the rectangular limiting frame includes two horizontal limiting bars and two vertical limiting bars; when the connecting seat is located on the vertical track and moves, one end of the two side panels of the ice frame is always in contact with the horizontal limiting bar; when the connecting seat is located on the horizontal track and moves, the upper ends of the two side panels of the ice frame are always in contact with the horizontal limiting bar.

[0011] By adopting this technical solution, the circular track is located within a rectangular limit frame, and the horizontal and vertical limit bars of the rectangular limit frame act as limiters for the ice frame. When the connecting seat is located on the vertical track and moves, one end of the ice frame's two side panels always contacts the horizontal limit bars, ensuring that the ice frame remains horizontal during vertical movement. When the connecting seat is located on the horizontal track and moves, the upper ends of the ice frame's two side panels always contact the horizontal limit bars, ensuring that the ice frame remains horizontal during horizontal movement, ensuring that ice cubes are placed stably.

[0012] Optionally, one end of the end plate is rotatably connected to the bottom plate, and the bottom of the end plate is vertically fixedly connected to a connecting plate; when the two ice frames are in the same horizontal position, the ice frames squeeze the connecting plate downward, causing the end plate to flip outward from the ice frames, forming a connection between the internal spaces of the two ice frames; a reset component is also provided in the ice frame to drive the end plate to reset to a vertical state.

[0013] By adopting the above technical solution, when the two ice frames are in the same horizontal position, the ice frames squeeze the connecting plate and flip it down, so that the end plate flips outwards of the ice frames, forming a connection between the internal spaces of the two ice frames, which makes it easier for the ice cubes to move towards the ice frame at the rear end along the material conveying direction. The ice cubes in the ice frame at the rear end become more, so when replenishing ice cubes, only the ice frame at the front end needs to be replenished; a reset member is also provided in the ice frame to drive the end plate to return to a vertical state, so that the end plate remains vertical when not connected, thereby preventing ice cubes from leaking out.

[0014] Optionally, the reset member is a tension spring, one end of the tension spring is connected to the upper end, and the other end is connected to the inner wall of the side plate.

[0015] By adopting the above technical solution, the reset member adopts a tension spring, which can effectively provide power for resetting the end plate, ensuring that the end plate can quickly return to a vertical state when not squeezed, thereby ensuring the normal use function of the ice frame.

[0016] Optionally, a storage hopper is fixed to the upper end surface of the top plate, and the bottom of the storage hopper is connected to the material delivery pipe.

[0017] By adopting the above technical solution, the storage hopper realizes centralized storage of ice cubes, which is convenient for manual or automatic addition of ice cubes into the feed pipe. The operation is convenient and quick, which improves the practicality of the device and can replenish ice cubes into the ice water pool in time to ensure that the low temperature environment in the ice water pool is continuously stable.

[0018] Optionally, the discharge port of the feed pipe is vertically slidably connected to a sealing plate, an elastic member is installed between the top plate and the sealing plate to push the sealing plate to close the discharge port, and a push rod is fixed to the lower end of the sealing plate for contacting the side plate; when the connecting seat is located on the horizontal track at the upper end, the ice placing frame squeezes the push rod upward to make the outlet of the feed pipe in a fully open state.

[0019] By adopting the above technical solution, the discharge port of the feed pipe is vertically slidably connected to the sealing plate, and an elastic member is installed between the top plate and the sealing plate to push the sealing plate to close the discharge port, and the push rod at the lower end of the sealing plate contacts the side plate. When the connecting seat is located on the horizontal track at the upper end, the ice frame is placed to squeeze the push rod upward to fully open the outlet of the feed pipe. This structure can realize the automatic discharge of ice cubes, and can open the discharge port in time when ice cubes need to be added. After the ice cubes are added, the discharge port can be automatically closed to prevent excessive addition of ice cubes or loss of cold, thereby improving the intelligence and automation level of the device and further enhancing the cooling effect and energy-saving performance.

[0020] In summary, this application has at least one of the following beneficial effects: 1. By setting up a heat preservation cover on the open position above the ice water pool, the loss of low-temperature cold energy in the ice water pool is significantly reduced, thereby reducing the melting rate of ice cubes and extending the time the ice water pool maintains an effective low-temperature environment; 2. The flip structure of the end plate and the coordination of the storage hopper, feeding pipe and blocking plate make it easy to replenish ice cubes. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present application is further described in detail below with reference to the accompanying drawings.

[0024] The present application discloses an ultra-low temperature abalone freshness-preserving cooling device. Figure 1 、 2 The cooling device includes an ice water pool 1, an insulation cover 3, and two ice frames 7. The ice water pool 1 adopts a rectangular frame structure extending in a specific conveying direction. A conveyor belt 2 is installed inside the ice water pool 1. The conveyor belt 2 runs along the extension direction of the ice water pool 1. The conveyor belt 2 includes a material input section, a material horizontal conveying section, and a material output section, which are used to convey abalone and other materials to be processed in the ice water pool 1. The conveyor belt 2 can be made of a material that is resistant to low temperatures and has good flexibility and load-bearing capacity, such as a strong PVC conveyor belt. Its width is adapted according to the actual abalone processing volume and the size of the ice water pool 1.

[0025] Reference Figure 1 、 2 The heat preservation cover 3 is arranged at the open position above the ice water pool 1, playing a key role in heat preservation. The heat preservation cover 3 includes two top plates 4 and two parallel side plates 5. The top plate 4 is a flat plate structure made of a heat preservation material with a certain thickness, such as a polyurethane heat preservation board, which can effectively block the heat exchange inside and outside the ice water pool 1 and reduce the escape of cold. A feed pipe 6 is connected to the top plate 4. This feed pipe 6 extends obliquely toward the inside of the ice water pool 1. The material of the feed pipe 6 can be stainless steel. The diameter of the pipe is determined according to the amount of ice added and the conveying speed. The inner wall of the feed pipe 6 is smooth, which facilitates the smooth sliding of ice into the ice frame 7 in the ice water pool 1.

[0026] Reference Figure 2 、 3Two ice storage racks 7 are used to store ice cubes. Each ice storage rack 7 comprises a base plate 8, two parallel side panels 9, and an end panel 10 disposed at the end of the base plate 8. The base, the two side panels 9, and the end panel 10 form a rectangular receiving trough for the ice cubes. The base plate 8 is evenly distributed with water-permeable holes to ensure that the ice cubes are fully exposed to the water, maintaining the low temperature of the ice water in the ice water pool 1. The two side panels 9 are fixed to either side of the base plate 8, perpendicular to the base plate 8. A rotating shaft 11 is fixed in the middle of the side away from each other.

[0027] Reference Figure 4 、 5 A circular track 12 is fixed to the adjacent sides of the two side panels 5. This circular track 12 is a rectangular structure consisting of two vertical tracks 13 and two horizontal tracks 14. The vertical tracks 13 and the horizontal tracks 14 are connected by a circular arc transition, forming a continuous and smooth motion trajectory. Two connecting seats 15 are installed on the circular track 12. The circular track 12 can be made of high-strength aluminum alloy. Two roller sets 36 are rotatably connected to the bottom of the two connecting seats 15. Each roller set 36 includes two rollers with parallel axes. The circular track 12 is located between the two rollers of each roller set 36, allowing the two connecting seats 15 to move along the trajectory of the circular track 12, ensuring the stability and smoothness of the two connecting seats 15 when moving on the track.

[0028] Reference Figure 3 、 4 The two ice frames 7 are rotatably connected to the connecting seats 15 on the circular track 12 through the rotating shaft 11. At the same time, a limiting member 16 is provided on the side plate 5. When the ice frame 7 moves, the limiting member 16 can ensure that the ice frame 7 is always in a horizontal state.

[0029] Reference Figure 4 、 5 The side panels 5 are provided with a drive assembly for driving the two connecting seats 15 to move synchronously clockwise in the same direction. The drive assembly may utilize a motor 21 coupled with a transmission mechanism comprising gears 22 and a chain 23. The drive assembly rotates within the circular track 12 to connect four rectangularly arranged gears 22, with a chain 23 wound around the four gears 22. The motor 21 is fixed to the outside of the side panels 5, and the output shaft of the motor 21 extends into the side panels 5 and is fixedly connected to one of the gears 22 to control the rotation of the chain 23. A connecting rod 24 is welded or threaded onto the connecting seat 15, the other end of which is fixedly connected to the chain 23, so that when the chain 23 rotates, it can move the connecting seat 15. In other embodiments, the drive assembly may also utilize a transmission mechanism such as a motor 21 or a belt to achieve synchronous movement of the connecting seat 15.

[0030] When the two connecting seats 15 are respectively located in the middle position of the two vertical tracks 13, that is, the initial position of the two connecting seats 15, the two ice frames 7 are connected end to end and are at the same water level of the ice water pool 1. At this time, the ice cubes are evenly distributed, and a relatively stable low-temperature environment is formed in the ice water pool 1, which is convenient for pre-cooling treatment of abalone.

[0031] When the connecting seat 15 at the front end moves to the front end position of the upper horizontal track 14, the corresponding ice frame 7 is close to the outlet of the feeding pipe 6, and the feeding pipe 6 is now located at the rear end of the ice frame 7. When the connecting seat 15 moves the corresponding ice frame 7 to the rear end, the ice cubes discharged by the feeding pipe 6 can be evenly replenished on the ice frame 7.

[0032] Reference Figure 2 、 4 The limiting member 16 includes a rectangular limiting frame 17 welded to the inner wall of the side panel 5, and the circular track 12 is located in the rectangular limiting frame 17. The rectangular limiting frame 17 is composed of two horizontal limiting bars 18 and two vertical limiting bars 19. When the connecting seat 15 is located on the vertical track 13 and moves, the side surfaces of one end of the two side panels 5 of the ice storage frame 7 always contact the horizontal limiting bars 18; when the connecting seat 15 is located on the horizontal track 14 and moves, the upper ends of the two side panels 5 of the ice storage frame 7 always contact the horizontal limiting bars 18. In this way, whether the ice storage frame 7 moves vertically or horizontally, it can maintain a horizontal state, ensuring that the ice cubes are placed stably.

[0033] Reference Figure 3 , both side panels 5 and the end panel 10 are slidably connected with an extended floating plate 25. When the connecting seat 15 moves toward the lower transverse track 14, the extended floating plate 25 slides out of the side panels 5 and the end panel 10, preventing the floating ice from escaping from the ice frame 7. The extended floating plate 25 is made of lightweight, low-temperature-resistant materials, such as plastic and polyethylene, to ensure normal operation in ultra-low temperature environments. The sliding of the extended floating plate 25 can be achieved by providing a structure with a slide groove in the side panels 5 and the end panel 10. A limit block is provided at the bottom of the extended floating plate 25, and a limit ring is fixed to the notch of the slide groove. The limit ring prevents the limit block from escaping from the slide groove, thereby forming a sliding connection for the extended floating plate 25.

[0034] Reference Figure 3 One end of the end plate 10 is pivotally connected to the base plate 8, and a connecting plate 29 is fixedly connected vertically to the bottom of the end plate 10. When the two ice storage frames 7 are at the same horizontal position, the ice storage frames 7 press the connecting plate 29 downward, causing the end plate 10 to tilt outward from the ice storage frames 7, thus connecting the internal spaces of the two ice storage frames 7. This allows ice cubes to move toward the rear ice storage frame 7 in the direction of material conveyance, gradually increasing the amount of ice cubes in the rear ice storage frame 7. Therefore, when refilling ice cubes, only the front ice storage frame 7 needs to be replenished.

[0035] A reset member 30 is also provided within the ice storage frame 7 to reset the end plate 10 to its vertical position. This reset member 30 is a tension spring, one end of which is connected to the upper end of the end plate 10 and the other end to the inner wall of the side plate 5. When the ice storage frame 7 is no longer pressing against the connecting plate 29, the tension of the tension spring resets the end plate 10 to its vertical position, preventing ice from leaking out.

[0036] Reference Figure 2 、 6 A storage hopper 31 is fixed to the upper end of the top plate 4, the bottom of which is connected to the delivery pipe 6. This hopper 31 provides centralized storage for ice cubes, facilitating manual or automatic addition of ice cubes to the delivery pipe 6. A blocking plate 32 is vertically slidably connected to the delivery pipe 6's outlet. A switch slot 35 is defined at the delivery pipe 6's outlet, into which the blocking plate 32 slides. The switch slot 35 extends downward from the top and does not penetrate the delivery pipe 6. When the blocking plate 32 slides down and contacts the bottom of the switch slot 35, the delivery pipe 6 is sealed.

[0037] An elastic member 33 is installed between the top plate 4 and the sealing plate 32 to push the sealing plate 32 to close the discharge port. The elastic member 33 can be an elastic element such as a spring or an elastic sponge pad. A push rod 34 for contacting the side plate 5 is fixed to the lower end of the sealing plate 32. Two push rods 34 can be provided, corresponding to the two side plates 5 respectively. An opening for the push rod 34 to extend is provided at the bottom of the switch slot 35. The push rod 34 can extend downward from the switch slot 35 through the opening. When a connecting seat 15 is located on the upper end of the horizontal track 14, the ice frame 7 presses the push rod 34 upward, causing the outlet of the feed pipe 6 to fully open, thereby realizing the automatic discharge of ice cubes.

[0038] The implementation principle of the ultra-low temperature abalone freshness-preserving cooling device of the present application embodiment is as follows: When needing to lock freshness treatment to abalone, first the abalone after boiling is sent on the conveyor belt 2 in the ice water pond 1 by conveyor, conveyor belt 2 transports abalone forward in the ice water pond 1, and meanwhile, the low-temperature frozen water in the ice water pond 1 cools abalone quickly. Along with the gradual melting of ice cube, when needs replenish ice cube, start drive assembly, make connector 15 drive ice frame 7 to move, make one of them ice frame 7 near feed pipe 6 outlet, squeeze and open blocking plate 32, then ice cube is added from storage hopper 31, ice cube enters in ice frame 7 by feed pipe 6, after completing ice cube replenishing, drive assembly drives connector 15 and ice frame 7 to reset again, guarantees to maintain enough ice quantities in the ice water pond 1.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
