The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings.

[0025] It should be understood that the drawings are only used to illustrate the present application.

[0026] An antifreeze ventilation device for quick freezing equipment, such as Figure 1-Figure 5 As shown, it includes a fan 7 arranged on the quick-freezing equipment 1, an air inlet main pipe connected to the fan 7, a branch pipe 3 connected to the air inlet main pipe, and an air outlet main pipe connected to the branch pipe 3. The fan 7 extracts normal temperature air and transports it to each pipe. The air flowing out of the fan 7 passes through the air inlet main pipe, the branch pipe 3 and the air outlet main pipe in sequence.

[0027] like Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 As shown, a fan 7 is provided to extract room temperature air for heat exchange. The fan 7 can be any fan 7 that can extract air. In this embodiment, the fan 7 is a diagonal flow fan 7. The fan 7 can be provided at any position of the quick-freezing device 1. However, the temperature around the quick-freezing device 1 may be lower than the room temperature. Therefore, the diagonal flow fan 7 is provided at the top of the quick-freezing device 1. Since the cold air accumulates downward, the diagonal flow fan 7 is provided at the top to extract the air with the largest temperature difference from the cold air.

[0028] like Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 As shown, the air inlet main pipe includes a first air inlet main pipe 21 connected to the fan 7 and a second air inlet main pipe 22 connected to the first air inlet main pipe 21. Since the fan 7 is arranged at the top of the quick-freezing equipment 1, in order to transport air from the top to the bottom of the quick-freezing equipment 1, the first air inlet main pipe 21 is arranged along the height direction of the quick-freezing equipment 1 and introduces air into the second air inlet main pipe 22. The second air inlet main pipe 22 is arranged at the bottom of the quick-freezing equipment 1 and is connected to the branch pipe 3. After the air flowing out of the first air inlet main pipe 21 enters the second air inlet main pipe 22, it is evenly distributed to the branch pipe 3. The branch pipe 3 exchanges heat with the cold air at the bottom, thereby increasing the temperature at the bottom of the quick-freezing equipment 1. The second air inlet main pipe 22 can be connected to the branch pipe 3 vertically or at an angle, as long as the second air inlet pipe and the branch pipe 3 are reliably connected. In this embodiment, the second air inlet main pipe 22 and the branch pipe 3 are connected by a tee.

[0029] A third air inlet main pipe 23 is provided between the first air inlet main pipe 21 and the second air inlet main pipe 22. The third air inlet main pipe 23 is provided at the bottom of the quick-freezing equipment 1 and arranged side by side with the branch pipe 3. The air in the first air inlet main pipe 21 flows to the third air inlet main pipe 23, then to the second air inlet main pipe 22, and then to the branch pipe 3 for heat exchange with the cold air at the bottom. The third air inlet main pipe 23 can also be omitted, and the first air inlet main pipe 21 and the second air inlet main pipe 22 can be directly connected. The third air inlet main pipe 23 can be provided to perform heat exchange with the cold air at the bottom of the equipment. The first air inlet main pipe 21 and the third air inlet main pipe 23 are connected by an elbow, and the third air inlet main pipe 23 and the second air inlet main pipe 22 are connected by an elbow.

[0030] The outer diameters of the first air inlet main pipe 21 , the second air inlet main pipe 22 and the third air inlet main pipe 23 are all 75 mm.

[0031] like Figure 2 as well as Figure 4As shown, the number of the branch pipes 3 can be set as needed. In this solution, 6 branch pipes 3 are set, and all the branch pipes 3 are connected to the second air inlet main pipe 22 and the air outlet main pipe. The 6 branch pipes 3 are evenly arranged at the bottom of the quick-freezing equipment 1 to heat up the cold air at the bottom of the quick-freezing equipment 1. The branch pipes 3 can be arranged in parallel or crosswise, as long as the sealing of the connection and the heating of the cold air at the bottom are guaranteed. In this solution, the branch pipes 3 are arranged in parallel and evenly at the bottom of the quick-freezing equipment 1. The branch pipes 3 are all arranged at the bottom of the quick-freezing equipment 1 to heat up the cold air at the bottom of the quick-freezing equipment 1 and prevent the cold air from damaging the floor. Therefore, the temperature of the wind entering the branch pipes 3 is greater than the temperature at the bottom of the quick-freezing equipment 1.

[0032] The outer diameter of the branch pipe 3 is set to 50 mm.

[0033] One end of all the branch pipes 3 is connected to the second air inlet main pipe 22 through a tee, and the other end of all the branch pipes 3 is connected to the air outlet main pipe through a tee. At the same time, a bundle joint is provided to ensure the sealing of the pipe connection to prevent air leakage.

[0034] like Figure 2 、 Figure 3 as well as Figure 4 As shown, the air outlet main pipe includes a first air outlet main pipe 41 connected to each branch pipe 3, a second air outlet main pipe 42 connected to the first air outlet main pipe 41 and a third air outlet main pipe 43 connected to the second air outlet main pipe 42. The first air outlet main pipe 41 is connected to each branch pipe 3, and the second air outlet main pipe 42 is arranged along the height direction to transport the air after heat exchange to the top of the quick-freezing equipment 1. The third air outlet main pipe 43 blows out the received low-temperature air. The third air outlet main pipe 43 can be not set. The third air outlet main pipe 43 is an extension of the second air outlet main pipe 42, which transports the low-temperature air to the top of the quick-freezing equipment 1 and blows the air that is lower than the room temperature after heat exchange to the top of the equipment to avoid direct discharge at the bottom, causing cold air to accumulate at the bottom of the equipment and damage the floor. At the same time, the temperature at the top of the equipment is higher than other positions of the equipment, which can be warmed up.

[0035] The specific process of the antifreeze ventilation device is as follows:

[0036] The diagonal flow fan 7 sucks in the normal temperature air at the top of the quick-freezing equipment 1 and then transports it to the first air inlet main pipe 21. After being transported by the first air inlet main pipe 21 set along the height direction, the air is transported to the third air inlet main pipe 23, and the third air inlet main pipe 23 then transports the air to the second air inlet main pipe 22. In the process of passing through the third air inlet main pipe 23, the normal temperature air will first exchange heat with the cold air at the bottom of the quick-freezing equipment 1, and then enter the second air inlet main pipe 22. The temperature of the air after heat exchange with the cold air is still higher than the temperature of the cold air at the bottom of the equipment; the air after heat exchange is evenly distributed to each branch pipe 3 from the second air inlet main pipe 22. The air in each branch pipe 3 exchanges heat with the cold air at the bottom of the quick-freezing equipment 1 again, and then flows through the first air outlet main pipe 41 to the second air outlet main pipe 42. After passing through the second air outlet main pipe 42 set along the height direction, it finally flows to the top of the quick-freezing equipment 1 through the third air outlet main pipe 43, and repeats this cycle to ensure the temperature of the bottom of the quick-freezing equipment 1 and prevent damage to the floor.

[0037] like Figure 1 、 Figure 4 as well as Figure 5 As shown, in order to facilitate the installation of pipelines, a support frame 5 is provided at the bottom of the quick-freezing equipment 1 to support it. The branch pipelines 3, the second air inlet main pipe 22, the third air inlet main pipe 23, and the first air outlet main pipe 41 are all provided on the support frame 5, and each pipeline is connected to the support frame 5 via a U-shaped pipe clamp. The support frame 5 is formed by welding a number of square tubes and is used to support the quick-freezing equipment 1 so that it does not come into direct contact with the ground, replacing the existing cement foundation. The support frame 5 is detachably connected to the quick-freezing equipment 1, which is superior to the existing cement foundation and can reduce the overall weight of the equipment. It is convenient to install the quick-freezing equipment 1 on other floors besides the first floor, expanding the use scenarios. At the same time, it will not cause excessive load on the floor, playing a safety protection role, and is convenient for cleaning the bottom of the quick-freezing equipment 1.

[0038] In order to facilitate the adjustment of the height between the quick-freezing equipment 1 and the ground, an adjusting bolt 51 is provided on the support frame 5 , and the height of the quick-freezing equipment 1 can be changed by adjusting the adjusting bolt 51 .

[0039] In order to better dissipate the cold air at the bottom of the quick-freezing device 1, a sealing plate 6 is provided on the quick-freezing device 1. The sealing plate 6 surrounds the quick-freezing device 1 circumferentially. The sealing plate 6, the quick-freezing device 1, and the ground together form a sealed space. The support frame 5 is located within the sealed space, and all pipes provided on the support frame 5 are also located within the sealed space. The sealing plates 6 can be provided in multiple pieces, and the multiple sealing plates 6 are tightly connected to form a sealed environment at the bottom of the device, ensuring that the cold air at the bottom does not leak out. A certain temperature is maintained in the enclosed space at the bottom, which better ensures the control of the bottom temperature, reduces or eliminates the generation of water droplets, and ensures the service life of the bottom plate at the bottom of the device.

[0040] The utility model mainly designs an antifreeze ventilation device for quick-freezing equipment, and arranges a fan 7 on the quick-freezing equipment 1. The fan 7 extracts air at room temperature and transports it to the bottom of the quick-freezing equipment 1 through the air inlet main pipe and the branch pipe 3. The cold air accumulates at the bottom of the quick-freezing equipment 1. The temperature of the air extracted by the fan 7 is higher than the temperature of the bottom of the quick-freezing equipment 1. Through heat exchange, the temperature of the bottom of the quick-freezing equipment 1 gradually increases until it approaches room temperature, preventing the cold air from accumulating at the bottom of the quick-freezing equipment 1 and causing the floor to freeze and crack or seep water, thereby extending the service life of the floor. The supporting frame 5 is arranged to enrich the use scenarios of the quick-freezing equipment 1, further ensuring the safety and sanitation of the bottom area of the quick-freezing equipment 1, and the sealing plate 6 is arranged to enclose and form a sealed space, thereby ensuring the appropriate temperature at the equipment site, reducing the amount of manual operation and the safety of the customer's later holding.
