[0002] With the rapid development of my country's economy, low-temperature refrigerated logistics technology has also advanced rapidly. During cold chain distribution, some foods and medicines need to be stored at low temperatures. Cold storage panels are a commonly used device. However, cold storage panels must be frozen before use. Traditional cold storage panels are frozen and placed in a low-temperature warehouse, where they are cooled by cold air. This results in poor heat exchange, long processing time, and low cold storage panel turnover.

[0003] Therefore, there is an urgent need to develop a technology that can quickly freeze cold storage plates. Summary of the Invention

[0017] The present invention will be further described below with reference to the accompanying drawings and specific implementation examples.

[0018] like Figure 1 The refrigeration device for rapidly freezing cold storage plates of the present invention includes a refrigerant circulation system and a secondary coolant circulation system. Specifically, the refrigerant circulation system includes a compressor 1, a condenser 2, a throttle valve 3, and a cold storage water tank 4.

[0019] The refrigerant outlet of the compressor 1 is connected to the refrigerant inlet of the condenser 2, the refrigerant outlet of the condenser 2 is connected to the refrigerant inlet of the throttle valve 3, and the refrigerant outlet of the throttle valve 3 is connected to the refrigerant inlet of the cold storage water tank 4. The refrigerant outlet of the cold storage water tank 4 is connected to the refrigerant inlet of the compressor 1. The purpose of cooling the secondary coolant in the cold storage water tank can be achieved through the refrigerant circulation system.

[0020] Specifically, the brine circulation system includes a cold water tank 4, a quick-freezing unit 5, a valve 6, and a water pump 7. The brine outlet of the cold water tank 4 is connected to the valve 6, which is connected to the inlet of the water pump 7. The outlet of the water pump 7 is connected to the cold plate inlets 13 and 15. Cold plate outlets 14 and 16 are connected to a shutoff valve 22, which is connected to the brine inlet of the cold water tank 4. This brine circulation system enables rapid freezing of the cold plate.

[0021] It should be noted that the size of the cold storage water tank and the number of quick freezers can be adjusted according to actual production needs. One cold storage water tank can be used with multiple quick freezers.

[0022] like Figure 2 As shown, the quick freezer 5 includes left and right cold plates 8, a lower cold plate 9, a hydraulic device 10, a slide rail 11, a connecting hose 12, left and right cold plate refrigerant inlet pipes 13, left and right cold plate refrigerant outlet pipes 14, a lower cold plate refrigerant inlet pipe 15, and a lower cold plate refrigerant outlet pipe 16.

[0023] Specifically, the coolant flows from the coolant outlet of the cold storage tank into the cold plate inlet, and then flows out of the cold plate outlet and into the cold storage tank inlet. When the feeding is completed, the left and right cold plates 8 connected to the hydraulic device 10 are driven by the hydraulic device 10 to achieve full contact between the cold storage plates, the left and right cold plates 8, and the lower cold plate 9, thereby improving the freezing efficiency. The left and right cold plates 8 are connected to the left and right cold plate coolant inlet pipes 13 and the left and right cold plate coolant outlet pipes 14 via connecting hoses 12, ensuring that the coolant can still flow into the left and right cold plates during the cold plate clamping process. The slide rails are closely attached to or embedded in the lower cold plate.

[0024] like Figure 3 As shown, a baffle 17 is provided inside the left and right cold plates 8. Figure 4 The lower cold plate is provided with a baffle 2 18. The arrangement of the baffle can fully disturb the coolant and increase the heat exchange efficiency.

[0025] like Figure 5 The feeding device shown includes a feeding trough 19 , a feeding baffle 20 , and a feeding robotic arm 21 .

[0026] Specifically, when feeding, the cold storage plates are stacked in the cold storage tank 19. The feeding robot 21 pushes the feeding baffle 19 to push the cold storage plates between the left and right cold plates to complete the feeding process. When discharging, the robot pushes the cold storage plates out of the freezer, thus completing the discharge process.

[0027] In summary, the present invention provides a refrigeration device for rapidly freezing cold storage plates. This device utilizes a cold storage water tank to rapidly freeze the cold storage plates. This utilizes off-peak electricity, alleviating pressure on the power grid while improving economic efficiency. The use of a quick freezer with adjustable cold plate spacing ensures full contact between the cold plates and the cold storage plates, improving freezing efficiency. This device has significant practical significance.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
