Description

Technical Field

[0001] This utility model belongs to the technical field of food quick-freezing equipment, specifically relating to a tunnel-type quick-freezing device for marine multi-layer mesh belts. Background Technology

[0002] With the rapid development of the global food processing industry, the application of freezing and preservation technology is becoming increasingly widespread. Especially in the marine fisheries and seafood processing industry, marine quick-freezing equipment, as one of the key pieces of equipment, plays a vital role in maintaining product quality and extending shelf life.

[0003] Traditional marine quick-freezing equipment typically employs a single-layer conveyor belt design. While this method is simple in structure and easy to maintain, it has certain limitations in practical applications. To ensure sufficient freezing time to achieve the desired low-temperature effect, traditional equipment often requires a long conveyor path, resulting in a large overall size and occupying limited space on board. The increased air heat load due to the wide refrigeration area leads to higher energy consumption. When production scales up, simply increasing the number of machines to meet demand further exacerbates the space occupation problem and is not conducive to cost control and optimization under large-scale operations. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a marine multi-layer mesh belt tunnel-type quick-freezing device. By setting up multiple parallel conveyor mesh belts in the vertical direction, the device significantly reduces the size of the entire equipment extending along the horizontal axis without reducing the material movement length, thereby optimizing space utilization. Furthermore, it reduces energy consumption and improves freezing efficiency while ensuring the product freezing effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tunnel-type quick-freezing device for marine multi-layer mesh belts, comprising an insulated storage body, wherein the insulated storage body is provided with an inlet and an outlet at both ends;

[0006] It also includes three layers of parallel stacked conveyor belts, including an upper conveyor belt, a middle conveyor belt and a lower conveyor belt;

[0007] It also includes a material guiding mechanism, which is located at the end of each layer of conveyor belt and is used to transfer materials to the adjacent layer of conveyor belt;

[0008] It also includes air coolers, including evaporators and centrifugal fans, for forming an annular airflow covering the conveyor belt;

[0009] It also includes support frames, including air cooler support frames and conveyor belt support frames;

[0010] The upper conveyor belt extends from the inlet to the outlet and is equipped with a guide plate assembly at the end. The material is transferred through the receiving transition plate at the beginning of the middle conveyor belt.

[0011] The conveying direction of the middle layer conveyor belt is opposite to that of the upper layer, extending from the discharge port to the inlet port, and is equipped with a guide plate assembly at the end, which transfers materials through the receiving transition plate at the beginning of the lower layer conveyor belt.

[0012] The lower conveyor belt has the opposite conveying direction to the middle layer, extending from the inlet to the outlet.

[0013] The air coolers are spaced apart on the support frame. After being cooled by the evaporator, the cold air is circulated by the centrifugal fan to the material area above the conveyor belt.

[0014] Preferably, the material guiding mechanism includes a material guiding plate assembly with an adjustable guiding angle, which achieves material deflection through the combined action of gravity and the material guiding plate.

[0015] Preferably, the evaporator and centrifugal fan of the air cooler are integrated on the same air cooler support frame.

[0016] Preferably, the support frame is arranged at intervals along the direction from the inlet to the outlet, respectively supporting the air cooler, the upper conveyor belt, the middle conveyor belt and the lower conveyor belt.

[0017] Preferably, the upper layer drive reducer is configured near the discharge port of the upper layer conveyor belt;

[0018] The middle layer conveyor belt is equipped with a middle layer drive reducer near the feed inlet;

[0019] The lower layer conveyor belt is equipped with a lower layer drive reducer near the discharge port.

[0020] Preferably, the conveyor belt has a three-level stacked structure, forming an interlaced and reverse S-shaped material conveying path.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. Space optimization: By using a multi-layered vertical mesh belt layout (upper layer → middle layer → lower layer), the horizontal dimensions of the device are significantly shortened while maintaining the total material conveying path length (ensuring freezing time), thus solving the problem of excessive space occupation on board by traditional single-layer equipment.

[0023] 2. Increased capacity per unit area: The three-stage mesh belt collaborative conveying realizes three freezing processes of materials within the same horizontal projection area, improving freezing efficiency per unit space and adapting to the needs of large-scale operations in limited space on board.

[0024] 3. Optimization of freezing time and path: By alternating reverse conveying of the middle and lower mesh belts, an S-shaped material movement path is formed, which extends the residence time of the material in the cold zone (equivalent to the freezing effect of a single-layer long path) without increasing the overall length of the equipment.

[0025] 4. Improved energy efficiency: The air coolers are centrally and intermittently arranged, and the cold air covers the material area on the multi-layer mesh belt through the annular wind field, reducing the air heat load caused by the dispersed cooling area of ​​traditional single-layer equipment and reducing the overall energy consumption.

[0026] 5. Adaptable to ship operation scenarios: The compact multi-layer design directly solves the problem of space constraints on board, while the modular support frame and air cooler layout adapt to the stability requirements of ship turbulence environment. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] The following reference Figures 1-4 This application describes a tunnel-type quick-freezing device for marine multi-layer mesh belts, provided in one embodiment.

[0034] A tunnel-type quick-freezing device for marine multi-layer mesh belts includes an insulated storage body 1, with an inlet 2 and an outlet 3 at each end of the insulated storage body 1.

[0035] It also includes three parallel stacked conveyor belts, including an upper conveyor belt 4, a middle conveyor belt 5 and a lower conveyor belt 6;

[0036] It also includes a material guiding mechanism 12, which is located at the end of each layer of conveyor belt and is used to transfer materials to the adjacent layer of conveyor belt.

[0037] It also includes a cooler 11, which includes an evaporator 111 and a centrifugal fan 112, for forming an annular airflow covering the conveyor belt;

[0038] It also includes a support frame 10, including a cooler support frame 101 and a conveyor belt support frame 102;

[0039] The upper conveyor belt 4 extends from the inlet 2 to the outlet 3, and is equipped with a guide plate assembly at the end. It transfers materials through the receiving transition plate 13 at the beginning of the middle conveyor belt 5.

[0040] The conveying direction of the middle layer conveyor belt 5 is opposite to that of the upper layer, extending from the discharge port 3 to the inlet port 2. The end is equipped with a guide plate assembly, which transmits materials through the receiving transition plate 13 at the beginning of the lower layer conveyor belt 6.

[0041] The conveying direction of the lower conveyor belt 6 is opposite to that of the middle layer, extending from the inlet 2 to the outlet 3;

[0042] The air coolers 11 are arranged at intervals on the support frame 10. After the cold air is cooled by the evaporator 111, it is circulated by the centrifugal fan 112 to the material area above the conveyor belt.

[0043] Furthermore, the material guiding mechanism 12 includes a material guiding plate assembly with an adjustable guiding angle, which achieves material deflection through the combined action of gravity and the material guiding plate.

[0044] Furthermore, the evaporator 111 and centrifugal fan 112 of the air cooler 11 are integrated on the same air cooler support frame 101.

[0045] Furthermore, the support frame 10 is arranged at intervals along the direction from the feed inlet 2 to the discharge outlet 3, respectively supporting the air cooler 11, the upper conveyor belt 4, the middle conveyor belt 5 and the lower conveyor belt 6.

[0046] In a further embodiment, an upper drive reducer 7 is configured near the discharge port 3 on the upper conveyor belt 4;

[0047] A middle layer drive reducer 8 is configured near the feed inlet 2 on the middle layer conveyor belt 5.

[0048] The lower layer drive reducer 9 is configured near the discharge port 3 on the lower layer conveyor belt 6.

[0049] In a further embodiment, the conveyor belt has a three-layer stacked structure, forming an interlaced reverse S-shaped material conveying path. Through the alternating reverse layout of the three layers of conveyor belts (upper layer → middle layer → lower layer), the freezing time is extended in the vertical space, while the horizontal space occupied is only about 1 / 3 of the length of a single layer of conveyor belt (assuming the three layers are of equal length).

[0050] The specific working process of a marine multi-layer mesh belt tunnel-type quick-freezing device of this application is described in conjunction with the above embodiments:

[0051] 1. Feeding and upper conveying:

[0052] The material enters the insulated silo 1 from the feed inlet 2 and is carried by the upper conveyor belt 4, and is horizontally conveyed from the feed inlet 2 to the discharge outlet 3.

[0053] The drive is powered by the upper drive reducer 7 located near the discharge port 3, ensuring that the material continues to move towards the discharge end.

[0054] 2. Mid-layer reverse conveying and material guiding / deflection:

[0055] When the material reaches the end of the upper conveyor belt 4, it is guided by the adjustable angle guide plate assembly and turns under the action of gravity to fall into the receiving transition plate 13 of the middle conveyor belt 5.

[0056] The middle layer conveyor belt 5 is driven by the middle layer drive reducer 8 near the feed inlet 2, and conveys materials in the reverse direction from the discharge outlet 3 to the feed inlet 2, extending the residence time of materials in the cold zone.

[0057] 3. Lower layer re-turning and discharge:

[0058] When the material reaches the end of the middle conveyor belt 5, it is turned to the receiving transition plate 13 of the lower conveyor belt 6 by another set of guide plates.

[0059] The lower conveyor belt 6 is driven by the lower drive reducer 9 near the discharge port 3, and is horizontally conveyed again along the direction from the inlet 2 to the discharge port 3, and finally the material is sent out of the insulation warehouse from the discharge port 3.

[0060] 4. Cold air circulation and freezing:

[0061] The air cooler 11 cools the air through the evaporator 111, and the centrifugal fan 112 forces the cold air to circulate to the material area above each layer of conveyor belt.

[0062] After the cold air exchanges heat with the material, it flows back to the evaporator 111 to form an annular airflow, continuously reducing the material temperature until it is completely frozen.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
