Description

Technical Field

[0001] The utility model relates to the technical field of quick-freezing of shrimp tails, in particular to a quick-freezing device for shrimp tails. Background Art

[0002] A quick-freezing device for shrimp tails is a special device used to quickly freeze shrimp tails to maintain their freshness and taste. Among them, liquid nitrogen quick-freezing is relatively common. It mainly sprays liquid nitrogen on the shrimp tails conveyed on a conveyor belt. Utilizing the ultra-low temperature effect of liquid nitrogen, the water in the shrimp tails is quickly frozen to achieve the quick-freezing of shrimp tails.

[0003] In the prior art, when spraying liquid nitrogen on shrimp tails for quick-freezing, in order to prevent the rapid dissipation of liquid nitrogen, a cover frame is arranged at the position where liquid nitrogen is sprayed to ensure that the liquid nitrogen fully freezes the shrimp tails and realizes the quick-freezing of shrimp tails. When the shrimp tails are conveyed on the conveyor belt and pass through the cover frame, some shrimp tails will roll and contact the inner wall of the cover frame during the movement, causing the liquid on the shrimp tails to adhere to the cover frame. The liquid that has not been cleaned for a long time is prone to deterioration and will produce a bad smell. Operators need to regularly clean the liquid adhering to the cover frame. However, the cover frame on the existing quick-freezing device is integrally arranged, and its interior is not easy to clean. Therefore, we have designed a quick-freezing device for shrimp tails to solve the above problems. Summary of the Utility Model

[0021] Referring to Figures 1-4 , a quick-freezing device for shrimp tails includes a mounting frame 1. A conveyor belt 2 is installed on the mounting frame 1 and is driven by a driving motor (not shown in the figure). A guiding mechanism is fixedly installed on the side wall of the mounting frame 1. The guiding mechanism includes two fixing rods 6 fixedly installed on the side wall of the mounting frame 1. An inclined guide plate 7 is fixedly installed at the ends of the two fixing rods 6. Baffle plates 8 are fixedly installed on the front and rear side walls of the guide plate 7. Through the setting of the guiding mechanism, it can scrape off the shrimp tails adhered to the conveyor belt 2 after freezing.

[0022] A nitrogen storage tank 3 is fixedly installed at the inner top of the mounting frame 1. A valve is provided at the output end of the nitrogen storage tank 3. The output end of the nitrogen storage tank 3 is fixedly connected to a communicating pipe 4 that communicates with its interior. A plurality of spray nozzles 12 that communicate with its interior are fixedly installed at the bottom of the communicating pipe 4. Two sliding grooves 15 are opened at the bottom top of the mounting frame 1. A shielding mechanism is provided in each of the two sliding grooves 15. The shielding mechanism includes a sliding plate 10 slidably connected in the sliding groove 15. A connecting rod 11 is fixedly installed on the side wall of the sliding plate 10. A cover frame 5 is fixedly installed at the end of the connecting rod 11. Observation windows are provided on the side walls of the two cover frames 5. Through the setting of the observation windows, the operator can observe the freezing condition of the shrimp tails on the conveyor belt 2 through the observation windows. The side walls of the two cover frames 5 are in contact with each other, and bayonet openings 16 are opened at the tops of the two cover frames 5.

[0023] Two mounting plates 9 are fixedly installed at the bottom top of the mounting frame 1. A driving mechanism is provided between the two mounting plates 9. The driving mechanism penetrates through the two shielding mechanisms and is threadedly connected thereto. The driving mechanism includes a servo motor 13 fixedly installed on the side wall of one of the mounting plates 9. A double-headed screw 14 is fixedly installed at the end of the output shaft of the servo motor 13. The end of the double-headed screw 14 is rotatably connected to the side wall of the other mounting plate 9. The double-headed screw 14 penetrates through the two sliding plates 10 and is threadedly connected thereto. Through the setting of the shielding mechanism and the driving mechanism, it can quickly separate the cover frame 5, facilitating the operator to clean the liquid adhering to the inner wall of the cover frame 5 and avoiding the situation where the liquid deteriorates and produces an unpleasant smell, making the operator feel uncomfortable.

[0024] The functional principle of the present utility model can be elaborated through the following operation mode:

[0025] When it is necessary to quickly freeze the shrimp tails, first, the operator places a collection basin directly below the left side of the material guiding plate 7, starts the drive motor, and the drive motor drives the conveyor belt 2 to rotate. The shrimp tails are placed on the right side of the conveyor belt 2, and the conveyor belt 2 conveys the shrimp tails. The operator observes the shrimp tails on the conveyor belt 2 through the observation window. When the shrimp tails are about to pass by the nozzle 12, the operator opens the valve on the liquid nitrogen storage tank 3, and the liquid nitrogen in the liquid nitrogen storage tank 3 is sprayed onto the shrimp tails conveyed on the conveyor belt 2 through the nozzle 12 on the connecting pipe 4, so that the shrimp tails are quickly frozen. The frozen shrimp tails are conveyed to the left side of the conveyor belt 2. Finally, the frozen shrimp tails fall onto the material guiding plate 7 from the left side of the conveyor belt 2 and are collected in the collection basin through the guiding of the material guiding plate 7. The shrimp tails adhering to the surface of the conveyor belt 2 will fall off under the obstruction of the top of the material guiding plate 7 and are collected in the collection basin through the guiding of the material guiding plate 7;

[0026] When it is necessary to clean the liquid adhering to the inner wall of the cover frame 5, the operator controls the servo motor 13 to rotate. The servo motor 13 drives the double-headed screw 14 to rotate, and the double-headed screw 14 drives the two sliding plates 10 to slide away from each other. The sliding plates 10 drive the two cover frames 5 to slide away from each other through the connecting rods 11. At this time, the two cover frames 5 are separated. When the two cover frames 5 slide to both sides of the conveyor belt 2, the operator can clean the liquid adhering to the inner wall of the cover frame 5. After the cleaning is completed, the operator controls the servo motor 13 to rotate in the reverse direction, so that the two cover frames 5 slide towards each other. Finally, the side walls of the two cover frames 5 are in contact with each other, and the shrimp tail freezing operation can continue.

[0027] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
