Technical Field

[0002] Since the quick freezer uses air blowing and heat exchange to freeze, the frozen products are placed in the shelf cart, and the frozen products are evenly placed on each layer of the shelf cart. The low-temperature high-pressure airflow and the frozen products are forced to exchange heat to achieve rapid freezing. If the air duct layout of the quick freezer is unreasonable, it will cause uneven air blowing, resulting in inconsistent freezing time of frozen products. In order to ensure that all frozen products reach the set temperature requirements, the freezing time needs to be extended. This situation will increase the dry consumption of some frozen products. At the same time, the increase in freezing time also leads to an increase in product energy consumption. Summary of the invention

The axial flow fan inhales the low-temperature airflow of the heat exchanger and forcibly transports the low-temperature airflow to the air induced device. The high-pressure and low-temperature airflow changes its direction through the air induced device and then vertically enters the air guide device. The horizontal airflow guided layer by layer by the air guide device enters the air guide grille. The air guide grille adopts a modular arrangement, and the low-temperature airflow blown out through the air guide grille is evenly blown to each layer of frozen products on the shelf trolley.

[0005] A further improvement of the utility model is that the air induction device comprises an air induction frame with a multi-layer structure, and an adjustable air induction plate is installed on each layer of the air induction frame, and the air induction plate is in an arc shape.

[0006] A further improvement of the utility model is that sliding pins are provided at both ends of the guide plates, sliding grooves are provided at corresponding positions of the air guide frame, and the sliding pins are placed in the sliding grooves, that is, each layer of guide plates can be adjusted according to the requirements of the air duct cross section.

[0007] A further improvement of the utility model is that the wind guide device comprises a wind guide frame, and the wind guide plates are evenly distributed and installed on the wind guide frame in stages and can be adjusted horizontally.

[0008] A further improvement of the utility model is that the air guide grille is arranged at the air outlet end of the air guide device, and the air guide grille is composed of a plurality of groups of grille plates, each group of grille plates can rotate, and there is a core shaft in the middle of each group of grille plates, and both ends of the core shaft are supported in the grille frame, and the smooth side of one end is freely rotatable with the movable rubber ring on the grille frame, and the external thread structure at the other end is connected with the fixing nut on the outside of the grille frame, and the adjustment and locking nuts on the inside of the grille frame on the same side are used to lock the grille plate after adjusting the direction.

[0020] like Figure 1 As shown, a quick-freezing warehouse with uniform air blowing comprises a warehouse body 1, in which a shelf trolley 2, a heat exchanger 3 and an axial flow fan 4 are arranged. The axial flow fan 4 sucks the low-temperature airflow from the heat exchanger 3 and forcibly transports the low-temperature airflow to the air induced device 5. The high-pressure and low-temperature airflow changes its direction through the air induced device 5 and vertically enters the air guide device 6. The horizontal airflow guided layer by layer through the air guide device 6 enters the air guide grille 7. The air guide grille 7 adopts a modular arrangement, and the low-temperature airflow blown out through the air guide grille 7 is evenly blown to each layer of frozen products on the shelf trolley 2.

[0021] like Figure 2 As shown, the air induction device 5 includes an air induction frame 5-1 of a multi-layer structure, and each layer of the air induction frame 5-1 is equipped with an adjustable air induction plate 5-2, which is arc-shaped. The arc-shaped air induction plate 5-2 can reduce the loss of wind pressure while changing the direction of the air duct. Sliding pins 5-3 are provided at both ends of the air induction plate 5-2, and sliding grooves 5-4 are provided at corresponding positions of the air induction frame 5-1. The sliding pins 5-3 are placed in the sliding grooves 5-4, that is, each layer of the air induction plate 5-2 can be adjusted according to the requirements of the air duct cross section, and the adjustable air induction plate 5-2 can make the air volume of each layer of the air duct uniform.

[0022] like Figure 3 As shown, the air guide device 6 includes an air guide frame 6-1, and air guide plates 6-2 are evenly installed on the air guide frame 6-1 in stages and can be adjusted horizontally so that each layer can be evenly blown.

[0023] like Figure 4 and Figure 5As shown, the air guide grille 7 is arranged at the air outlet end of the air guide device 6, and the air guide grille 7 is composed of a plurality of groups of grille plates 7-1, each group of grille plates 7-1 can rotate, and there is a core shaft 7-2 in the middle of each group of grille plates 7-1, and both ends of the core shaft 7-2 are supported in the grille frame 7-3, one end of the smooth side is freely rotatable with the movable rubber ring 7-4 on the grille frame 7-3, and the other end of the external thread structure is connected with the fixing nut 7-5 on the outside of the grille frame 7-3, and the adjustment and locking nut 7-6 on the inside of the grille frame 7-3 on the same side is used for locking the grille plate 7-1 after adjusting the direction.

[0024] In the closed insulation storage body, the axial flow fan sucks the low-temperature airflow from the heat exchanger and forces it to the induced draft device. The high-pressure and low-temperature airflow changes its direction through the induced draft device and vertically enters the air guide device. Arc-shaped air guide plates are evenly installed on the air guide frame to guide the high-pressure and low-temperature airflow layer by layer to the horizontal direction. The horizontal airflow guided layer by layer through the air guide device enters the air guide grille.

[0025] After the grille module is installed, it can be precisely adjusted according to the specifications of the frozen products in each layer of the frozen product cart to ensure that the frozen products are evenly blown around them, so that each layer of frozen products is blown evenly, shortening the freezing time and reducing energy consumption. After the grille module is installed, products of different specifications can be frozen at the same time, and the modular design of the grille can be adjusted independently by area. The utility model can achieve rapid freezing of small batches. When a small batch of goods is put into storage, the grille plates in other areas are closed, and the goods display area is concentrated for blowing and heat exchange, which increases the local air volume and shortens the freezing time.
