Description

Technical Field

[0001] This utility model relates to the field of storage tanks, and in particular to a low-temperature preservation storage tank for pet food raw materials. Background Technology

[0002] Low-temperature storage tanks for pet food ingredients are used during the production and processing of pet food to temporarily preserve feed ingredients at low temperatures, allowing the feed ingredients to remain fresh for a long time. They are widely used in pet food production.

[0003] However, existing storage tanks have significant drawbacks in actual use. After raw materials are poured into the tank through the top inlet cover, they mainly rely on gravity to naturally accumulate, easily forming a dense and uneven pile. This accumulation method leads to severe bridging and compression phenomena inside the material, blocking the cold air flow channels. Cold air cannot effectively penetrate to the center and bottom areas of the material, and instead escapes more from the gaps between the tank wall and the material. As a result, the temperature distribution of different parts of the material inside the tank is extremely uneven, easily forming cooling dead zones and causing internal heat accumulation, which seriously affects the overall preservation effect. This may not only cause some raw materials to deteriorate, but also require more energy to maintain the low temperature, increasing operating costs. Utility Model Content

[0004] The main objective of this invention is to provide a low-temperature preservation storage container for pet food raw materials, which can effectively solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A low-temperature storage tank for pet food ingredients includes a storage tank body, a support frame, and a ladder frame. The support frame is fixedly installed at the bottom of the storage tank body, and the ladder frame is fixedly installed at the front outer side of the storage tank body. A sealed top cover is fixedly installed at the top of the storage tank body. An insulated inner liner is fixedly installed inside the storage tank body. A lifting screw is movably installed at the top of the storage tank body and the insulated inner liner. Two fixing rings are fixedly installed on the inner wall of the insulated inner liner. A lifting sleeve is threaded onto the outer side of the lifting screw. A connecting frame is fixedly installed on the outer side of the lifting sleeve. A lifting ring is welded onto the outer side of the connecting frame, and the lifting ring is located above the fixing rings. Multiple connecting rod structures are provided between the fixing rings and the lifting rings.

[0007] As a further embodiment of this utility model, an inlet cover is fixedly installed on the upper end of the sealed top cover, and a discharge pipe is fixedly installed on the bottom of the storage tank and the insulated inner liner.

[0008] As a further embodiment of this utility model, the upper end of the lifting screw extends through to the upper end of the storage tank, and a rotating handle is fixedly installed on the upper end of the lifting screw.

[0009] As a further embodiment of this utility model, the fixed ring and the lifting ring have the same diameter, and the lifting ring is fitted to the inner wall of the heat-insulating inner liner.

[0010] As a further embodiment of this utility model, the linkage structure includes a mounting shaft, a lifting linkage, a connecting ball, and a rotating mounting plate. The mounting shaft is fixedly mounted on the upper end of the fixed ring, the lifting linkage is movably mounted on the outside of the mounting shaft, the connecting ball is fixedly mounted on the upper end of the lifting linkage, and the rotating mounting plate is movably sleeved on the outside of the connecting ball.

[0011] As a further embodiment of this utility model, the rotating mounting plate is fixedly installed at the lower end of the lifting ring, the lower end of the lifting connecting rod rotates around the mounting shaft, and the connecting ball rotates within the rotating mounting plate.

[0012] Compared with existing technologies, this utility model has the following advantages: By rotating the handle to drive the lifting screw to rotate, the lifting sleeve and the lifting ring connected thereto perform vertical lifting and lowering movements. The movement of the lifting ring is converted into a gentle pushing force on the material through multiple linkage structures. When the lifting ring descends, the linkages gradually unfold, applying uniform pressure to the upper layer of raw materials, making them flat and compact. When the lifting ring rises, the lifting linkages retract, making room for the introduction of new raw materials. This process realizes dynamic and adjustable layered management of the materials in the tank. This mechanical layered structure breaks the natural stacking state of the materials, forming regular gap channels between each layer of raw materials, so that the low-temperature cold air introduced from the top can penetrate each layer of materials evenly and smoothly, rather than just escaping from the edge of the tank. This solves the technical problems of cooling dead corners, internal heat accumulation, and uneven preservation caused by excessively dense material stacking in traditional storage tanks, and greatly improves the overall low-temperature preservation effect.

Figures 1-4 The system includes a storage tank 1, a support frame 2, and a ladder frame 3. The support frame 2 is fixedly installed at the bottom of the storage tank 1, and the ladder frame 3 is fixedly installed at the front of the outer side of the storage tank 1. A sealed top cover 4 is fixedly installed at the top of the storage tank 1. An insulated inner liner 6 is fixedly installed inside the storage tank 1. A lifting screw 8 is movably installed on the top of the storage tank 1 and the insulated inner liner 6. Two fixing rings 9 are fixedly installed on the inner wall of the insulated inner liner 6. A lifting screw sleeve 10 is threaded on the outer side of the lifting screw 8. A connecting frame 11 is fixedly installed on the outer side of the lifting screw sleeve 10. A lifting ring 12 is welded to the outer side of the connecting frame 11, and the lifting ring 12 is located above the fixing rings 9. Multiple connecting rod structures 13 are provided between the fixing rings 9 and the lifting ring 12.

[0020] Please refer to this carefully. Figure 1 and Figure 2 An inlet cover 5 is fixedly installed on the upper end of the sealed top cover 4, and a discharge pipe 7 is fixedly installed on the bottom of the storage tank 1 and the insulated inner liner 6.

[0021] Specifically, the raw materials are put into the insulated inner liner 6 of the storage tank 1 by opening the input cover 5. The discharge pipe 7 is used to discharge the raw materials in the insulated inner liner 6. Cold air is injected through the pipe on the sealed top cover 4 to create a low-temperature environment in the insulated inner liner 6 to keep the raw materials fresh.

[0022] Please refer to this carefully. Figure 2 and Figure 3 The upper end of the lifting screw 8 extends through to the upper end of the storage tank 1, and a rotating handle 18 is fixedly installed on the upper end of the lifting screw 8.

[0023] Please refer to this carefully. Figure 2 and Figure 3 The fixed ring 9 and the lifting ring 12 have the same diameter, and the lifting ring 12 is fitted to the inner wall of the heat-insulating inner liner 6.

[0024] Specifically, the rotating handle 18 rotates the lifting screw 8, and the rotation of the lifting screw 8 causes the lifting sleeve 10 to rise and fall, thereby driving the connecting frame 11 and the lifting ring 12 to rise and fall.

[0025] Please refer to this carefully. Figure 3 and Figure 4 The linkage structure 13 includes a mounting shaft 14, a lifting linkage 15, a connecting ball 16, and a rotating mounting plate 17.

The connecting ball 16 is fixedly mounted on the upper end of the lifting linkage 15. The rotating mounting plate 17 is movably sleeved on the outside of the connecting ball 16.

[0026] Please refer to this carefully. Figure 3 and Figure 4 The rotating mounting plate 17 is fixedly installed at the lower end of the lifting ring 12, the lower end of the lifting connecting rod 15 rotates around the mounting shaft 14, and the connecting ball 16 rotates within the rotating mounting plate 17.

[0027] Specifically, the rotation of the lifting screw 8 drives the lifting ring 12 to rise and fall. The lifting ring 12 pulls the lifting connecting rod 15 to rotate, thereby changing the distance between the lifting ring 12 and the fixed ring 9. After the raw materials are put into the heat-insulating inner liner 6, the raw materials are layered by changing the distance between the lifting ring 12 and the fixed ring 9, so that the cooling gas can enter the heat-insulating inner liner 6 more fully and evenly to keep the raw materials at low temperature.
