[0002] The current quick-freezing industry requires higher and higher freezing volume and temperature, and the size of the equipment is getting larger and larger, resulting in higher and higher energy consumption. Since the evaporator inside the quick-freezing machine is prone to frost on the surface after a long period of operation, especially for large-scale quick-freezing equipment, if the evaporator surface is frosted, it will directly affect the heat exchange performance of the evaporator, thereby greatly increasing the operating burden of the compressor, which not only affects its refrigeration effect and quick-freezing efficiency, but also greatly increases the energy consumption of the equipment, resulting in an increase in production costs.

The utility model arranges air guide channels 6 between the circulation fan 5 and the first spiral bracket 3, and between the circulation fan 5 and the second spiral bracket 4, which can effectively guide the cold air in the warehouse 1, and quickly flow the cold air blown out by the circulation fan 5 to the first spiral bracket 3 and the second spiral bracket 4, so as to avoid the cold air staying in the warehouse 1 for a long time or flowing only in a small range, so as to realize sufficient circulation of the cold air in the warehouse 1 and improve the overall refrigeration efficiency.

[0026] As an embodiment of the present utility model, the wind direction at the air outlet end of the air guide channel 6 near the first spiral bracket 3 points to the center of the first spiral bracket 3. After the cold air blows to the internal baffle of the first spiral bracket 3, it is split to both sides, so that a part of the cold air passes through the side of the first spiral bracket 3 close to the evaporation component, and the other part of the cold air passes through the side of the first spiral bracket 3 away from the evaporation component; the wind direction at the air outlet end of the air guide channel 6 near the second spiral bracket 4 points to the center of the second spiral bracket 4. After the cold air blows to the internal baffle of the second spiral bracket 4, it is split to both sides, so that a part of the cold air passes through the side of the second spiral bracket 4 close to the evaporation component, and the other part of the cold air passes through the side of the second spiral bracket 4 away from the evaporation component, which is beneficial to the uniform distribution of the cold air output by the air guide channel 6, thereby improving the circulation efficiency of the cold air and the overall refrigeration efficiency.

[0027] As an embodiment of the utility model, a first movable part is provided between the first air guide plate 61 and the evaporation component, and a second movable part is provided between the second air guide plate 62 and the evaporation component; the first air guide plate 61 rotates around the first movable part, and the second air guide plate 62 rotates around the second movable part to adjust the size of the air outlet end of the air guide channel 6. In actual use, depending on the different products on the conveyor belt 2, the requirements for the freezing temperature and the amount of cold air in the warehouse 1 are also different. The first air guide plate 61 and the second air guide plate 62 are designed to be movable and can rotate around the first movable part and the second movable part respectively. According to actual use requirements, the first air guide plate 61 and the second air guide plate 62 can be brought closer or separated to achieve appropriate adjustment of the size of the air outlet end of the air guide channel 6, which can meet the freezing requirements of different products and improve the overall compatibility and efficiency of use.

[0028] As an embodiment of the utility model, the first movable part and the second movable part can adopt a variety of structures, such as hinges, rotating shafts, etc., and the first movable part and the second movable part can adopt the same structure or different structures according to actual needs, without any connection or influence between them.

[0029] Preferably, the first movable part is a first rotating shaft arranged on the evaporation component, the first air guide plate 61 is sleeved on the first rotating shaft, and the first air guide plate 61 rotates and swings around the first rotating shaft; the second movable part is a second rotating shaft arranged on the evaporation component, the second air guide plate 62 is sleeved on the second rotating shaft, and the second air guide plate 62 rotates and swings around the second rotating shaft.

[0030] Preferably, the first air guide plate 61 and the second air guide plate 62 are both moved by being driven by a driving component, and the driving component can adopt a variety of structures, such as a motor, a cylinder, etc. Preferably, the driving component selects a control method for the first air guide plate 61 and the second air guide plate 62 according to actual usage requirements. For example, the driving component can control the first air guide plate 61 and the second air guide plate 62 to move synchronously, or separately control the first air guide plate 61 or the second air guide plate 62 to move independently, such as only controlling the first air guide plate 61 to move while the second air guide plate 62 is stationary, or the first air guide plate 61 is stationary and only the second air guide plate 62 is controlled to move.

[0031] Preferably, the first air guide plate 61 and the second air guide plate 62 are respectively provided with a limiting component to limit the movement range of the first air guide plate 61 and the second air guide plate 62 to move closer to or separate from each other, thereby avoiding unnecessary interference or even collision between the first air guide plate 61 and the second air guide plate 62, or between the first air guide plate 61 and other components, or between the second air guide plate 62 and other components, causing unnecessary damage, thereby improving the overall safety and stability of use.

[0032] As an embodiment of the utility model, the first air guide plate 61 and the second air guide plate 62 are both arc-shaped. When the speed of the cold air output by the circulating fan 5 is too large, the straight plate will convert part of the dynamic pressure into static pressure, while the first air guide plate 61 and the second air guide plate 62 are arc-shaped plates, which can alleviate or even avoid the conversion of dynamic pressure into static pressure, thereby improving the guiding effect on the cold air.

[0033] As an embodiment of the present invention, the first air guide plate 61 is close to the air inlet end of the evaporation component, and the second air guide plate 62 is far away from the air inlet end of the evaporation component. According to the positional relationship between the first spiral bracket 3, the second spiral bracket 4, the evaporation component and the air guide channel 6, the air guide channel 6 is biased toward one side of the first spiral bracket 3 and the second spiral bracket 4. Since the first spiral bracket 3 and the second spiral bracket 4 are symmetrically arranged relative to the evaporation component, the first spiral bracket 3 is used as an example for explanation. The situation of the second spiral bracket 4 is the same as that of the first spiral bracket 3. The cold wind blows to the first spiral bracket 3. After the internal baffle of the first spiral bracket 3, the air is divided into two sides, with the side of the first spiral bracket 3 close to the evaporation component as the inner side, and the side of the first spiral bracket 3 close to the side wall of the warehouse 1 as the outer side. The outer area of ​​the first spiral bracket 3 is much larger than the inner side, about 3 times the inner area. Therefore, if the cold air around the first spiral bracket 3 circulates evenly, it is necessary to meet the requirement that the air volume passing through the outer side of the first spiral bracket 3 is 3 times the inner air volume. Therefore, the structure of the first air guide plate 61 and the second air guide plate 62 must meet the requirement of guiding three quarters of the cold air in the air guide channel 6 to the outer side of the first spiral bracket 3. There are the following two structures:

[0034] Structure 1: The end of the first air guide plate 61 away from the circulation fan 5 is gathered toward the inner side of the air guide channel 6, and the end of the second air guide plate 62 away from the circulation fan 5 is gathered toward the inner side of the air guide channel 6, and the gathering angle of the second air guide plate 62 is smaller than the gathering angle of the first air guide plate 61;

[0035] Structure 2: One end of the first air guide plate 61 away from the circulation fan 5 is gathered toward the inner side of the air guide channel 6 , and one end of the second air guide plate 62 away from the circulation fan 5 is open to the outer side of the air guide channel 6 .

[0036] As an embodiment of the utility model, the evaporation component includes an evaporator 71 and a hollow chamber 72. The hollow chamber 72 is arranged at the air outlet end of the evaporator 71. The circulating fan 5 is arranged on the side wall of the hollow chamber 72. The gas output by the evaporator 71 converges in the hollow chamber 72 to form a high-pressure area in the hollow chamber 72. The circulating fans 5 are all connected to the high-pressure area to ensure that the air pressure, temperature and air volume entering each circulating fan 5 are equal.

[0037] Preferably, the side wall includes a first side wall facing the first spiral bracket 3 and a second side wall facing the second spiral bracket 4, and the first side wall and the second side wall are parallel to the wind direction of the air outlet end of the evaporator 71. Part of the circulation fan 5 is arranged on the first side wall, and part of the circulation fan 5 is arranged on the second side wall. The circulation fan 5 is directed toward the first spiral bracket 3 or the second spiral bracket 4, so that the circulation fan 5 is arranged vertically to the evaporator 71. There is no flow field interference between the two rows of separately arranged circulation fans 5, which can effectively avoid performance loss of the circulation fan 5.

[0038] Preferably, three circulation fans 5 are provided on the first side wall and the second side wall. While satisfying the installation space of the circulation fans 5, the number of the circulation fans 5 is increased as much as possible, which can effectively improve the circulation efficiency of the cold air in the warehouse 1 and improve the overall refrigeration efficiency.

[0039] As an embodiment of the utility model, the air inlet and outlet ends of the evaporator 71 are both provided with a defrost mechanism, the defrost mechanism includes a plurality of nozzles, each nozzle is directed to the fins of the evaporator 71, and through the cooperation between the two defrost mechanisms respectively arranged at the two ends of the evaporator 71, each fin has a front and a rear nozzle corresponding thereto, and the nozzles spray liquid to the fins of the evaporator 71 to defrost, thereby ensuring that the evaporator 71 has a high heat exchange efficiency, which is beneficial to reducing the operating burden of the compressor, thereby reducing the energy consumption of the equipment and reducing production costs, avoiding abnormal phenomena such as frosting of the evaporator 71 after long-term operation, thereby increasing the energy consumption of the equipment, and improving the stability of the equipment.

[0040] In summary, the utility model provides a double-spiral quick-freezing machine, which can effectively guide the cold air in the warehouse 1, and quickly direct the cold air blown out by the circulating fan 5 to the first spiral bracket 3 and the second spiral bracket 4, so as to prevent the cold air from staying in the warehouse 1 for a long time or flowing only in a small range, so as to realize the full circulation of the cold air in the warehouse 1 and improve the overall freezing efficiency; the wind direction at the air outlet end of the air guide channel 6 points to the center of the first spiral bracket 3 or the center of the second spiral bracket 4, which is conducive to the uniform distribution of the cold air output by the air guide channel 6; through the first spiral bracket 3 and the second spiral bracket 4, the cold air blown out by the circulating fan 5 can be directed to the first spiral bracket 3 and the second spiral bracket 4, so as to achieve the uniform distribution of the cold air output by the air guide channel 6; A movable part and a second movable part can realize appropriate adjustment of the size of the air outlet end of the air guide channel 6, which can meet the freezing requirements of different products and improve the overall compatibility and efficiency of use; the first air guide plate 61 and the second air guide plate 62 are both arc-shaped, which can improve the guiding effect on cold air; the hollow chamber 72 can ensure that the air pressure, temperature and air volume entering each circulation fan 5 are equal; the circulation fan 5 and the evaporator 71 are arranged vertically, and there is no flow field interference between the two rows of separately arranged circulation fans 5, which can effectively avoid the performance loss of the circulation fan 5.
