Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, and in particular to a refrigeration tank for rapid cooling. Background Technology

[0002] The working principle of an ice cream machine is as follows: First, the ingredients are added to the ingredient tank. Then, the ingredients are mixed evenly with air by an air-milk pump and conveyed to the refrigeration tank. The expanded milk mixture is stirred and gradually cooled in the freezing tank, while its viscosity increases. When the desired viscosity is reached, it is pushed to the outlet by a screw conveyor. Then, the outlet is opened, and the machine extrudes the finished ice cream.

[0003] In the existing technology, most refrigeration tanks used for refrigeration directly inject the refrigerant into a set of pipes. The pipes are in close contact with the refrigeration tank for refrigeration. There is also a pipe body between the pipes and the refrigeration tank. During the heat exchange process, the refrigerant also needs to conduct heat through the pipe body. In addition, there is a gap between the pipe body and the refrigeration tank, resulting in low heat conduction efficiency and poor refrigeration effect. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of the claimed invention.

[0025] Example:

[0026] like Figures 1 to 4 As shown, this embodiment provides a rapid cooling refrigeration tank, including a tank body 1 and a bushing 2 for refrigerant circulation. A hollow receiving cavity is defined inside the tank body 1. The bushing 2 is fitted inside the tank body 1. A spiral-shaped first groove 21 and a second groove 22 are respectively recessed from top to bottom on the outer side wall of the bushing 2. The outer side wall of the bushing 2 is connected to the inner side wall of the tank body 1 to form a first flow channel 3 in the first groove 21 and a second flow channel 4 in the second groove 22. An inlet 5 is provided at the lower end of the bushing 2 and an outlet 6 is provided at the upper end of the bushing 2. The inlet end of the first flow channel 3 and the inlet end of the second flow channel 4 are respectively connected to the inlet 5, and the outlet end of the first flow channel 3 and the outlet end of the second flow channel 4 are respectively connected to the outlet 6.

[0027] In this embodiment, a first flow channel 3 and a second flow channel 4 are defined between the outer wall of the bushing 2 and the inner wall of the barrel body 1. The input ends of the first flow channel 3 and the second flow channel 4 are respectively connected to the input port 5, and the output ends of the first flow channel 3 and the second flow channel 4 are respectively connected to the output port 6. This allows the external refrigerant to enter the first flow channel 3 and the second flow channel 4 through the input port 5, thereby enabling the refrigerant to flow quickly through the first flow channel 3 and the second flow channel 4 to the output port 6, and then be delivered to the evaporator through the output port 6. The structure is simple, and the dual flow channels enable the rapid delivery of refrigerant, thereby achieving the purpose of efficient refrigeration.

[0028] In this embodiment, a hollow receiving cavity is defined within the barrel body 1. A bushing 2 is fitted inside the barrel body 1, and a hollow cavity is also defined within the bushing 2. A spiral-shaped first groove 21 and a second groove 22 are respectively recessed from bottom to top on the outer wall of the bushing 2, and the first groove 21 and the second groove 22 are spaced apart by flanges. Since the outer ends of the first groove 21 and the second groove 22 are open, the outer wall of the bushing 2 is connected to the inner wall of the barrel body 1 through a mating connection, i.e., the outer wall of the bushing 2 abuts against the inner wall of the barrel body 1, thereby forming a first flow channel 3 in the first groove 21. The second groove 22 forms the second flow channel 4. An inlet 5 connected to the external refrigerant is opened at the lower end of the bushing 2, and an outlet 6 connected to the evaporator is opened at the upper end of the bushing 2. The inlet end of the first flow channel 3 and the inlet end of the second flow channel 4 are respectively connected to the inlet 5, and the outlet end of the first flow channel 3 and the outlet end of the second flow channel 4 are respectively connected to the outlet 6. In addition, since the refrigerant in the first flow channel 3 and the second flow channel 4 is in direct contact with the inner wall of the barrel body 1, the traditional pipe arrangement as an intermediate medium is reduced, and the contact area between the refrigerant in the first flow channel 3 and the second flow channel 4 and the barrel body is larger, resulting in higher heat exchange efficiency.

[0029] Furthermore, it also includes a feed pipe 7 and a discharge pipe 8, wherein one end of the feed pipe 7 is connected to the external refrigerant and the other end is connected to the inlet 5, and one end of the discharge pipe 8 is connected to the outlet 6 and the other end is connected to the evaporator.

[0030] Preferably, a first connecting groove 23 is recessed at the lower end of the outer wall of the bushing 2. One end of the first connecting groove 23 is connected to the input port 5, and the other end is connected to the input end of the first flow channel 3 and the input end of the second flow channel 4, respectively.

[0031] Specifically, the height of the cross-section of the first connecting groove 23 gradually increases along the output direction.

[0032] Furthermore, a second connecting groove 24 is recessed at the upper end of the outer wall of the bushing 2. One end of the second connecting groove 24 is connected to the output port 6, and the other end is connected to the output end of the first flow channel 3 and the output end of the second flow channel 4, respectively.

[0033] Preferably, the height of the cross-section of the second connecting groove 24 gradually decreases along the output direction.

[0034] In this embodiment, the feed pipe 7 is disposed inside the bushing 2, with one end connected to the external refrigerant and the other end connected to the input end of the inlet 5. The output end of the inlet 5 is connected to the input ends of the first flow channel 3 and the second flow channel 4 via the first connecting groove 23. The output ends of the first flow channel 3 and the second flow channel 4 are connected to the input end of the output port 6 via the second connecting groove 24. The output end of the output port 6 is connected to the evaporator via the discharge pipe 8, thereby allowing the external refrigerant to be transported sequentially through the feed pipe 7 and the inlet 5 to the first connecting groove 23. Since the height of the cross-section of the first connecting groove 23 gradually increases along the output direction, i.e., the height of the first connecting groove 23 gradually increases along the output direction, the height of the first connecting groove 23 gradually increases along the output direction. The end of the first connecting groove 23 closer to the inlet 5 is smaller than the end farther from the inlet 5. This allows the refrigerant on the first connecting groove 23 to be quickly delivered to the inlet end of the first flow channel 3 and the inlet end of the second flow channel 4, respectively. After entering the first flow channel 3 and the second flow channel 4, the refrigerant continues to be delivered from bottom to top. Then, since the height of the cross-section of the second connecting groove 24 gradually decreases along the output direction, that is, the end of the second connecting groove 24 closer to the outlet 6 is smaller than the end farther from the outlet 6, the refrigerant on the first flow channel 3 and the second flow channel 4 is quickly delivered to the outlet 6 through the second connecting groove 24, and then sequentially delivered to the evaporator through the outlet 6 and the discharge pipe 8.

[0035] More preferably, since the diameter of the feed pipe 7 is smaller than the diameter of the discharge pipe 8, the cross-sectional area of ​​the input port 5 is smaller than the cross-sectional area of ​​the output port 6, thereby achieving the purpose of rapid cooling.

[0036] Preferably, it also includes a connecting pipe 51, which is disposed inside the bushing 2, and the lower end of the connecting pipe 51 is fixedly installed on the inlet 5, while its upper end is connected to the feed pipe 7.

[0037] Furthermore, the connecting pipe 51 is made of stainless steel.

[0038] Specifically, it also includes an output connector 61, which is disposed inside the bushing 2, and one end of the output connector 61 is fixedly installed on the output port 6. The discharge pipe 8 is connected to the output port 6 through the output connector 61.

[0039] Specifically, the output connector 61 is made of stainless steel.

[0040] In this embodiment, a connecting pipe 51 and an output connector 61 are respectively arranged inside the bushing 2. The lower end of the connecting pipe 51 is fixedly installed on the inlet 5, and its upper end is connected to the feed pipe 7. At the same time, one end of the output connector 61 is fixedly installed on the outlet 6. The discharge pipe 8 is connected to the outlet 6 through the output connector 61, which facilitates the assembly of the feed pipe 7 and the discharge pipe 8, thereby effectively improving the assembly efficiency. More preferably, the material of the connecting pipe 51 is different from that of the feed pipe 7, and the material of the output connector 61 is different from that of the discharge pipe 8. Since the feed pipe 7 and the discharge pipe 8 are preferably made of copper, the materials of the connecting pipe 51 and the output connector 61 can be preferably made of stainless steel, thereby effectively reducing the production cost of the product while maintaining the cooling effect. In addition, in order to effectively ensure the cooling effect, the material of the connecting pipe 51 can also be set to be the same as that of the feed pipe 7, that is, the material of the connecting pipe 51 can also be made of copper.

[0041] In this embodiment, external refrigerant is fed into the first connecting groove 23 via the feed pipe 7. The first connecting groove 23 rapidly delivers the refrigerant to the first flow channel 3 and the second flow channel 4. The refrigerant then continues to spiral upwards within the first and second flow channels 3 and 4, before being rapidly delivered to the output port 6 via the second connecting groove 24. Since the feed pipe 7 is wound around the discharge pipe 8 at the end furthest from the input port 5, the refrigerant in the feed pipe 7 can be used to cool the refrigerant in the discharge pipe 8 after heat exchange, facilitating subsequent recycling. The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
