Description

Technical Field

[0001] This utility model relates to the field of frozen shrimp preservation technology, specifically to a frozen shrimp preservation and transportation box. Background Technology

[0002] Common frozen shrimp preservation techniques involve adding insulation materials and a cavity that can be filled with liquid nitrogen inside the container, then adding sealing strips to isolate the internal and external environments of the container, reducing heat exchange, and maintaining the freshness of frozen shrimp during long-distance transportation.

[0003] According to the Chinese patent publication CN217929360U, "A Spiral Freezing Device for Frozen Shrimp," the main feature described is the convenient cleaning of the conveyor belt achieved by setting up a cleaning component. This avoids the situation where frozen shrimp are contaminated with shrimp debris and fishy smells during transport, requiring subsequent manual cleaning, which is quite troublesome. The device eliminates the need for manual cleaning, thus facilitating conveyor belt cleaning. Furthermore, by setting up an adsorption component, it achieves the adsorption and treatment of irritating odors, preventing the accumulation of irritating odors in the freezer over a long period of use and thus avoiding environmental pollution.

[0004] During the unloading process at the port, due to fluctuations in operation time, the cooling of the transport box for frozen shrimp may be interrupted in some cases, causing the temperature of some of the frozen shrimp inside the transport box to rise, which affects the preservation effect of the frozen shrimp.

[0005] Therefore, a frozen shrimp preservation transport box is proposed to solve the problem that the freezing effect of frozen shrimp is affected by the interruption of cooling during unloading. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the freezing of frozen shrimp is interrupted during unloading, which affects the preservation effect of frozen shrimp. Therefore, a frozen shrimp preservation transport box is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a frozen shrimp preservation and transportation box, including a box body, a sealing door and a condensation device. An air inlet pipe is fixedly connected to one side of the condensation device. Four air distribution pipes are fixedly connected to the bottom side of the air inlet pipe. Spray nozzles are evenly fixedly connected to the bottom end of the air distribution pipes. A connecting plate is fixedly connected to the upper side of the inner side of the air distribution pipes. An airflow distribution plate is fixedly connected to one side of the connecting plate. The airflow distribution plate is inclined and has through holes evenly opened on it. A support frame is fixedly connected to the bottom side of the inner side of the box body. A return groove is opened on the support frame. An air outlet grille is fixedly connected to the upper end of the support frame. An air inlet grille is fixedly connected to the bottom end of the connecting plate. Four limiting grooves are opened at the bottom end of the air outlet grille. A partition plate is in contact with the limiting groove. Two adjacent partition plates are rotatably connected by a rotating shaft. A limiting block is fixedly connected to the side of the partition plate away from the rotating shaft. A pressure rod is inserted into the limiting block.

[0008] As a preferred technical solution of this utility model, the partition plate is evenly provided with guide grooves, which are located on both sides of the partition plate. By setting the guide grooves, condensation circulation can be facilitated.

[0009] As a preferred technical solution of this utility model, a fixing sleeve is sleeved at the bottom end of the pressure rod. The fixing sleeve is made of rubber material and is fixedly connected to the bottom limiting block. Another fixing sleeve is in contact with the support frame. By setting the fixing sleeve, the friction with the pressure rod is increased, and the stability of the pressure rod is improved.

[0010] As a preferred technical solution of this utility model, the support frame is rotatably connected to a baffle via a rotating shaft. The baffle contacts the return groove. By setting the baffle, the overflow of cold air can be reduced.

[0011] As a preferred technical solution of this utility model, a pad is provided between two adjacent support frames. The pad is fixedly connected to the bottom side of the box body, and the upper end of the pad contacts the air outlet grille. By setting an electric regulator, the stability of the air outlet grille is increased.

[0012] This utility model has the following advantages: by setting a bendable partition in the box to form a multi-layered partition structure, and with the help of the limiting block and the pressure rod, multiple partitions can be formed, reducing the leakage of cold air during unloading. Then, the air supplied by the condensing equipment passes through the air inlet pipe, air distribution pipe, air distribution plate, air outlet grille and air outlet grille, etc., to form a circulating airflow, which is convenient for providing condensation and preservation for frozen shrimp.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3 The frozen shrimp preservation and transport box shown includes a box body 1, a sealing door 2, and a condensing device 3. The condensing device 3 mainly refers to a freezer, which provides a stable low-temperature environment through self-cooling. An air inlet pipe 4 is fixedly connected to one side of the condensing device 3. Four air distribution pipes 5 are fixedly connected to the bottom side of the air inlet pipe 4. Spray nozzles 6 are evenly fixedly connected to the bottom end of the air distribution pipes 5. The air inlet pipe 4 provides an airflow channel and evenly sprays cold airflow through the air distribution pipes 5 and the spray nozzles 6 to contact the material. A connecting plate 7 is fixedly connected to the upper side of the inner side of the air distribution pipes 5. An airflow distribution plate 8 is fixedly connected to one side of the connecting plate 7. The airflow distribution plate 8 is inclined and... The airflow distribution plate 8 has through holes evenly distributed. A support frame 9 is fixedly connected to the bottom side of the box 1. A return groove is provided on the support frame 9. An air outlet grille 10 is fixedly connected to the upper end of the support frame 9. An air inlet grille is fixedly connected to the bottom end of the connecting plate 7. Four limiting grooves 11 are provided at the bottom end of the air outlet grille 10. A partition 12 is in contact with the limiting groove 11. Two adjacent partitions 12 are rotatably connected by a rotating shaft. A limiting block 13 is fixedly connected to the side of the partition 12 away from the rotating shaft. A pressure rod 14 is inserted into the limiting block 13. A pipe is fixedly connected to the bottom side of the box 1, and the pipe communicates with one side of the condensing equipment 3.

[0019] The partition plate 12 is provided with uniformly distributed guide grooves 18, which are located on both sides of the partition plate 12. By setting the guide grooves 18, a guide channel can be provided to facilitate the condensation of materials.

[0020] Among them, the bottom end of the pressure rod 14 is fitted with a fixing sleeve 15, which is made of rubber. The fixing sleeve 15 is fixedly connected to the bottom limiting block. Another fixing sleeve 15 is in contact with the support frame 9. By setting the fixing sleeve 15, the friction between the fixing sleeve 15 and the pressure rod 14 is increased.

[0021] The support frame 9 is rotatably connected to a baffle 16 via a rotating shaft. The baffle 16 contacts the return trough. By setting the baffle 16, the flow of cold air from the return trough can be reduced. Figure 1 The left side of the central support frame 9 overflows.

[0022] Among them, a pad strip 17 is provided between the two support frames 9. The pad strip 17 is fixedly connected to the bottom side of the inner side of the box 1. The upper end of the pad strip 17 contacts the air outlet grille 10. By setting the pad strip 17, the stability of the air outlet grille 10 can be increased.

[0023] Working principle: Frozen shrimp are placed into four identical spaces, each bounded by partition 12. The space is then limited by pressure rod 14 and fixing sleeve 15. The partition 12 connects to the connecting plate 7 and the support frame 9, allowing for individual circulation. When the material needs cooling, air is supplied to the air inlet pipe 4 through the condenser 3, and then falls onto the airflow distribution plate 8 after passing through the nozzle. Furthermore, the air inlet grille further refines the airflow. When the container body 1 needs to be unloaded, the partition 12 can be removed by disassembling the pressure rod 14, thereby reducing the amount of cold air generated during the unloading process.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] 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 the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
