Description

TECHNICAL FIELD

[0001] The application relates to the technical field of refrigeration storage, in particular to a high-efficiency energy-saving fresh agricultural product refrigeration storage with sterile circulating refrigeration. BACKGROUND

[0002] In the field of cold chain storage and food processing, quick-freezing refrigeration storage is widely used in the storage and processing of various fresh agricultural products due to its quick cooling and freshness locking characteristics. For fresh agricultural products, the sterility of the storage environment is directly related to the product quality and safety, so sterile circulating refrigeration has become one of the core requirements of fresh agricultural product refrigeration storage. At present, the refrigeration system of most quick-freezing refrigeration storage uses ammonia as the refrigerant, and the liquid supply mode is mainly ammonia pump liquid supply. This liquid supply mode can realize stable delivery of ammonia liquid to the quick-freezing chamber, guarantee the quick-freezing cooling effect, and meet the basic needs of quick-freezing of fresh agricultural products; Chinese Patent No. CN210718332U discloses a refrigeration storage quick-freezing component. The component is provided with an ammonia gas detector and a controller at the inner top end of the quick-freezing refrigeration storage, and is equipped with a fan, a gas conveying pipe, a treatment box, a water tank, a water pump and other components. When ammonia gas leakage occurs in the quick-freezing refrigeration storage, the ammonia gas detector detects the leakage and transmits an electric signal to the controller. The fan is started by the controller, and the ammonia gas in the refrigeration storage is discharged into the treatment box through the suction pipe. At the same time, the water pump sprays the water in the water tank through the spray pipe, so that the ammonia gas and the water are mixed to form ammonia water, which is then discharged to the water collecting pool through the drain pipe for collection, thereby realizing emergency treatment of ammonia gas and reducing the leakage hazard. Although the above-mentioned prior art can solve the safety protection problem of ammonia gas leakage to a certain extent, there is still obvious energy waste defect in actual application, which is difficult to meet the current energy saving and consumption reduction industry development demand. Specifically, in the operation cycle of the ammonia refrigeration system, the compressor of the refrigeration unit discharges high-temperature and high-pressure refrigerant gas. The gas needs to enter the condenser for heat exchange and cooling. The high-temperature and high-pressure refrigerant gas discharged by the compressor itself carries high heat energy and has certain kinetic energy. This part of energy is not effectively utilized in the system design of the existing quick-freezing refrigeration storage, but is directly dissipated to the environment through the condenser heat dissipation and other ways, resulting in a large amount of energy waste, poor energy saving effect of the whole system, and inconsistency with the current green and low-carbon industrial development trend.

[0021] Please refer to Figures 1-4The front side of the cold storage body 1 is provided with a cold storage entrance and exit 3, the inner side of the cold storage entrance and exit 3 is hinged with a cold storage sealing door 4, the cold storage sealing door 4 is sealed and covered on the outer side of the cold storage entrance and exit 3 through a door lock, the top of the cold storage body 1 is fixedly installed with an inclined ceiling 5, and the sunny surface of the inclined ceiling 5 is fixedly connected with a photovoltaic panel 6. During the application of the device, the cold storage sealing door 4, the door lock, the inclined ceiling 5 and the photovoltaic panel 6 can guarantee the sealing performance of the cold storage, maintain the stability of the internal refrigeration environment and assist in energy saving. The cooperation of the cold storage sealing door 4 and the door lock can effectively isolate the air circulation between the inside and outside, reduce the leakage of cold air in the cold storage, avoid the entry of warm air and impurities from the outside, guarantee the stability of the low-temperature environment in the cold storage, provide basic conditions for the sterile circulating refrigeration storage of fresh agricultural products, the inclined ceiling 5 can reduce the accumulation of rain and snow, protect the top structure of the cold storage body 1 and prolong the service life, and the photovoltaic panel 6 on the sunny surface can fully utilize solar energy to convert into electric energy, provide auxiliary power support for the operation of the device, reduce the dependence on external electric energy, improve the economy of the operation of the device, and meet the use demand of energy saving and consumption reduction.

[0022] The implementation principle of the sterile circulating refrigeration high-efficiency energy-saving fresh agricultural product cold storage provided in the embodiment of the application is as follows: when the device is used, first, the fresh agricultural products are placed in the cold storage through the cold storage entrance and exit 3 on the front side of the cold storage body 1. After the cold storage sealing door 4 is closed, the sealing and covering of the cold storage entrance and exit 3 are realized by means of the door lock, so as to guarantee the closed environment in the cold storage body 1 and lay a foundation for subsequent sterile circulating refrigeration. At the same time, the photovoltaic panel 6 on the sunny surface of the inclined ceiling 5 receives light and converts solar energy into electric energy, provides auxiliary power supply for the electric components such as the generator 253 of the refrigeration unit 23, reduces the consumption of external electric energy, the structure of the inclined ceiling 5 can also reduce the accumulation of rain and snow, guarantee the stable light efficiency of the photovoltaic panel 6, and then the refrigeration unit 23 in the unit installation groove 21 is started. After the refrigeration unit 23 is operated, the compressor in the refrigeration unit 23 starts to work, compresses the low-temperature and low-pressure refrigerant into high-temperature and high-pressure refrigerant gas, and discharges the gas from the output end of the compressor. The unit installation groove 21 provides a stable installation space for the refrigeration unit 23, so that the interference of the external environment on the operation of the refrigeration unit 23 can be avoided; After starting the refrigeration unit 23, the internal compressor starts to work, compresses the low-temperature and low-pressure refrigerant into high-temperature and high-pressure refrigerant gas and discharges from the output end. The unit installation groove 21 provides a stable installation space for the refrigeration unit 23, so that the refrigeration unit 23 is not disturbed by the external environment during operation, thereby ensuring the stable output of the high-temperature and high-pressure refrigerant gas. The high-temperature and high-pressure refrigerant gas discharged by the compressor enters the connecting main pipe 252 of the first energy storage module 25 at high speed, and then flows into the inside of the communication main shell 254. Due to the high flow rate of the refrigerant gas, when flowing through the vortex push blade 256, it will generate a thrust on the vortex push blade 256, driving the vortex push blade 256 to rotate the shaft 255. The shaft 255 drives the generator 253 shaft end to rotate synchronously through the sealing shaft coupling, realizes the power generation process, converts the kinetic energy of the refrigerant gas into electrical energy, the fixed frame 251 provides stable support for the generator 253 and the communication main shell 254 and other components, and the sealing shaft coupling avoids leakage of the refrigerant gas during the rotation of the shaft 255, so that the kinetic energy recovery process can be stable and efficient; The high-temperature and high-pressure refrigerant gas after completing kinetic energy recovery enters the heat exchange disc group 243 of the heat exchange module 24 through the connecting pipe 2432 of the first energy storage module 25. The connecting pipe 2432 guides the refrigerant gas into the inside of the heat exchange disc pipe 2433. The inside of the heat exchange tank 242 is pre-injected with cold water. The high-temperature refrigerant gas exchanges heat with the cold water when flowing in the heat exchange disc pipe 2433, releases its own heat, and makes the cold water absorb heat and increase in temperature. The bottom disc 241 provides installation support for the entire heat exchange module 24, so that the heat exchange tank 242 can be stably placed to ensure the heat exchange effect. At the same time, the heat dissipation assembly 244 outside the heat exchange tank 242 starts to work. The annular heat dissipation disc 2441 conducts the residual heat in the inside of the heat exchange tank 242 that is not completely absorbed by the cold water to itself, and then dissipates to the outside environment through the heat dissipation fins 2442. Since the annular heat dissipation disc 2441 and the heat dissipation fins 2442 are composed of high-thermal-conductivity aluminum alloy pipes, the heat conduction efficiency can be improved, thereby ensuring the sufficiency of the heat exchange process. Due to the principle that hot flow flows upwards and cold flow flows downwards, the high-temperature hot flow formed after the heat exchange tank 242 absorbs heat enters the heat preservation tank 223 of the second energy storage module 22 through the cold and hot flow flowing pipe 224 for storage. The top side plate 221 provides installation and fixing support for the heat preservation tank 223. The heat preservation sleeve 222 is wrapped outside the heat preservation tank 223 to reduce heat loss. The external water filling pipe connector can supplement cold water to ensure the continuous stability of heat energy storage. If hot water is needed, the hot water can be discharged through the drain pipe 225 after opening the drain valve 226 for daily life. The first heat preservation sleeve 227 and the second heat preservation sleeve 228 are wrapped outside the cold and hot flow flowing pipe 224 and the drain pipe 225, respectively, to further reduce heat loss during transportation. During the refrigeration of the cold storage, the refrigerating unit 23 is always running. Therefore, in the refrigerating unit 23 that is always running, the heat in the inside continuously acts on the second energy storage module 22 at the top, so as to ensure that the inside of the heat preservation tank 223 is hot water. At the same time, the heat dissipation assembly 244 at the bottom further improves the heat exchange and heat dissipation effect; The refrigerant gas cooled by the heat exchange module 24 is discharged through the bent communication pipe 2434 of the heat exchange disc group 243, and then enters the condenser of the refrigeration unit 23 to continue the subsequent refrigeration cycle process such as condensation, throttling and evaporation, and finally provides refrigeration capacity for the inside of the refrigeration storage body 1 to realize the refrigeration and preservation of fresh agricultural products. During the entire operation process, the refrigeration storage body 1 always maintains a closed state, the refrigeration unit 23 continuously operates to realize sterile circulating refrigeration, the photovoltaic panel 6 continuously generates power to assist power supply, and the first energy storage module 25 and the second energy storage module 22 continuously complete energy recovery and storage, so that the technical solution can be long-term, efficient and stable. The high-speed flow kinetic energy of the refrigerant gas is converted into electric energy by the cooperation of the vortex-shaped pushing blade 256 rotating shaft 255 of the first energy storage module 25 and the generator 253, the heat energy of the refrigerant gas is transferred by the heat exchange between the heat exchange disc pipe 2433 of the heat exchange module 24 and the cold water, and then the high-temperature hot stream is stored in the heat preservation tank 223 of the second energy storage module 22 for daily life hot water use. At the same time, the photovoltaic panel 6 converts solar energy into electric energy to assist power supply, which comprehensively solves the problem of energy waste caused by the fact that the heat energy and kinetic energy carried by the high-temperature and high-pressure refrigerant gas discharged by the compressor of the refrigeration unit 23 in the background technology are not utilized, and effectively improves the energy saving effect. By setting the cooperation of the refrigeration storage sealing door 4 and the door lock, the airtightness of the refrigeration storage body 1 is ensured, the cold air leakage is reduced, and the bacteria from the outside are prevented from entering, so as to realize sterile circulating refrigeration to ensure the preservation quality of fresh agricultural products. The structures work cooperatively, the unit placement groove 21, the bottom plate 241, the top side plate 221 and the fixing frame 251 respectively provide stable support for the corresponding parts, the heat dissipation assembly 244 improves the heat dissipation efficiency, the heat preservation structure reduces heat loss, and the stability and reliability of the operation are ensured. The heat preservation tank 223 of the second energy storage module 22 realizes heat energy storage, the hot water discharge is controlled through the drain valve 226 to improve the flexibility of heat energy utilization, the photovoltaic panel 6 continuously provides auxiliary electric energy, the first energy storage module 25 and the heat exchange module 24 are synchronized with the refrigeration unit 23 to realize the continuity of energy recovery to ensure long-term and efficient operation of the device.
