Description

Technical Field

[0001] The utility model belongs to a quick-freezing storage, in particular to an efficient integral quick-freezing storage. Background Art

[0002] The quick-freezing storage usually uses the way of heat exchange by blowing air through a heat exchanger to quickly freeze the frozen products in the shelf carts in the storage. If the air duct layout of the quick-freezing storage is unreasonable, it will cause uneven air blowing, resulting in a slow freezing speed. Under normal circumstances, the air guiding grille in the adjustable air damper is in a closed state. The high-pressure air flow blows into the low-pressure area from the bottom, and then from the bottom of the low-pressure area, from bottom to top, exchanges heat with the frozen products in the shelf carts in the low-pressure area, and finally is sucked into the air inlet side of the heat exchanger. Due to the low air pressure on the low-pressure side, especially the local area at the upper end of the low-pressure side is affected by the air pressure, there will be a phenomenon of uneven freezing effect in the local area.

[0003] The quick-freezing storage is often installed by on-site assembly. The on-site installation is time-consuming and laborious, and restricted by factors such as the site and tools, it often fails to meet the initial design requirements. Summary of the Invention

[0004] The purpose of the utility model is to overcome the above deficiencies and provide an efficient integral quick-freezing storage that can quickly freeze frozen products, reduce the dry loss of frozen products, and reduce the energy consumption of equipment.

[0005] The purpose of the utility model is realized through the following technical solutions: An efficient integral quick-freezing storage includes a storage body. Inside the storage body, there are shelf carts, a heat exchanger, and a centrifugal fan. Both the inlet and outlet ends of the storage body are provided with storage doors. The centrifugal fan sucks the low-temperature air flow of the heat exchanger and forcibly blows the low-temperature air flow to the surface of the frozen products. The frozen products are placed in a basin with mesh holes, and the basins are placed vertically and horizontally in the shelf carts. The high-pressure low-temperature air flow blows from top to bottom to the surface of the frozen products.

[0006] A further improvement of the utility model lies in that: The storage body is an integral heat-insulating storage body.

A steel structure bottom frame is installed at the lower part of the storage body, and the steel structure bottom frame is connected to the lower-end columns of the steel structure through bolts.

[0007] A further improvement of the utility model lies in that: An adjustable air damper steel frame is provided at the lower part inside the storage body, and an air guiding grille is provided in the air damper steel frame.

[0008] A further improvement of the utility model lies in that: The drain pipe of the heat exchanger extends to the outside of the storage body.

[0009] A further improvement of the utility model lies in that: Double-opening storage doors are provided at both the inlet and outlet ends of the storage body, and a movable ramp is provided below the storage doors.

[0010] A further improvement of the utility model lies in that: Heat-insulating top boards and heat-insulating bottom boards are respectively provided at the top and bottom of the storage body.

Specific implementation mode

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. The elements and features described in one implementation mode of the present utility model can be combined with the elements and features shown in one or more other implementation modes. It should be noted that, for the sake of clarity, the representation and description of components and processes that are irrelevant to the present utility model and known to those of ordinary skill in the art are omitted in the description. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0028] As Figure 1 and Figure 2 shown, a highly efficient integral quick-freezing storage includes a storage body 1. Inside the storage body 1, there are a shelf cart 2, a heat exchanger 3 and a centrifugal fan 4. The drain pipe 3-1 of the heat exchanger 3 extends to the outside of the storage body 1. Storage doors 5 are provided at both the inlet and outlet ends of the storage body 1. The storage doors can be double-opening storage doors. A movable ramp 8 is provided below the storage door 5 to facilitate the entry and exit of goods. Inside the closed heat-insulated storage body, the centrifugal fan 4 sucks in the low-temperature air flow of the heat exchanger 3 through a wind guide ring, and uses the characteristics of the large air volume and high air pressure of the centrifugal fan 4 to forcibly blow the low-temperature air flow onto the surface of the frozen products. The frozen products are placed in a basin body 6 with mesh holes, and the basin body 6 is placed vertically in the shelf cart 2. The high-pressure low-temperature air flow blows from top to bottom onto the surface of the frozen products. Since the air volume and air pressure directly act on the surface of the frozen products, the freezing speed is faster than the previous freezing speed. The present utility model omits the air duct layout, reduces the air pressure loss caused by the air duct layout, and improves the freezing speed.

[0029] Figures 3 to 5As shown in the figure, the library body 1 is an integral thermal insulation library body. The library body 1 is formed by connecting multiple library boards 1-1 into a whole. That is, embedded plate parts are installed inside the library boards 1-1, and each plate is connected into a whole through bolts. The lifting hooks 7 at the top of the library boards 1-1 are connected to the steel support frame 1-2 inside the library through bolts. A steel structure bottom frame 1-3 is installed at the lower part of the library body 1, and the steel structure bottom frame 1-3 is connected to the lower column 1-4 of the steel structure through bolts. Thermal insulation top plates 1-7 and thermal insulation bottom plates 1-8 are respectively provided at the top and bottom of the library body 1. During hoisting, the thermal insulation library body does not bear the weight of the products inside, which can simplify and lighten the library board structure. The production and installation of the library boards are also easier. During hoisting, the lifting hooks, the steel support frame inside the library, and the bottom frame are connected through bolts. On the premise of ensuring the strength of the bolts and the bottom frame, the integrated hoisting of the product is realized.

[0030] Figures 6 to 8 As shown in the figure, an adjustable air door steel frame 1-5 is provided at the lower part inside the library body 1. A guide air grille 1-6 is provided in the air door steel frame 1-5. The high-strength profiles ensure the strength and stability of the product. The middle adjustable air door steel frame divides the equipment into a high-pressure area and a low-pressure area. By adjusting the local air doors inside the steel frame, a part of the low-temperature air flow on the high-pressure side is introduced into the area with poor heat exchange, and most of the other air doors remain closed. The opening size of the air doors is adjusted on-site, with strong operability and practical convenience.

[0031] As Figure 9 described, round holes are evenly distributed at the bottom of the basin body 6 to enable the up-and-down circulation of the low-temperature air flow as much as possible and improve the heat exchange effect of the frozen products.

[0032] Finally, it should be noted that: Although the present invention and its advantages have been described in detail above, it should be understood that various changes, substitutions, and transformations can be made without exceeding the spirit and scope of the present invention defined by the appended claims. Moreover, the scope of the present invention is not limited to the specific embodiments of the processes, devices, means, methods, and steps described in the specification.
