Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figures 1-4 In this embodiment of the present invention, an energy storage refrigerated dryer includes a fixed box 1, a partition 2 fixedly connected inside the fixed box 1, an installation box 3 provided on one side of the partition 2, a heat exchange box 4 provided on the other side of the partition 2, a heat-conducting pipe 5 installed inside the heat exchange box 4, a wind duct 6 fixedly connected to the outer wall of the fixed box 1, a heat-conducting cylinder 7 installed inside the wind duct 6, a capillary tube 8 and a compressor 9 installed on the top of the fixed box 1, the liquid outlet end of the heat-conducting pipe 5 connected to the liquid inlet end of the capillary tube 8, the air outlet end of the capillary tube 8 connected to the air inlet end of the heat-conducting cylinder 7, the air outlet end of the heat-conducting cylinder 7 connected to the air inlet end of the compressor 9, the liquid outlet end of the compressor 9 connected to the liquid inlet end of the heat-conducting pipe 5, an air inlet 10 provided at one end of the wind duct 6, an air outlet 11 provided at the other end of the wind duct 6, a pressure valve installed inside the air outlet 11, and a drain outlet 12 provided at the bottom of the wind duct 6.

[0024] In operation, the compressor 9 first starts, and the room-temperature, high-pressure refrigerant liquid in the heat-conducting pipe 5 flows into the capillary tube 8 under the pumping force of the compressor 9. Then, as the room-temperature, high-pressure refrigerant liquid enters the heat-conducting cylinder 7 through the capillary tube 8, it changes from a high flow rate to a low flow rate, resulting in a significant pressure drop. This pressure drop lowers the boiling point of the refrigerant liquid, causing it to begin evaporating and absorbing heat, producing low-temperature refrigerant vapor. Finally, the low-temperature refrigerant vapor flows into the heat-conducting cylinder 7. The low-temperature refrigerant vapor in the heat-conducting cylinder 7 then absorbs heat from the airflow and is converted into room-temperature refrigerant vapor. Subsequently, the room-temperature refrigerant vapor is compressed by the compressor 9 to form a high-temperature refrigerant liquid. The high-temperature refrigerant liquid flows along the first connecting... The pipe 19 enters the heat-conducting pipe 5, thereby absorbing the heat in the gas entering the air duct 6 through the air inlet 10. In addition, the present invention uses a centrifuge to compress the air and inject it into the air duct 6, thereby forming high-pressure air in the air duct 6. The high-pressure air is compressed and the temperature rises. At this time, the greater the temperature difference between the air and the heat-conducting pipe 5, the higher the heat exchange rate between the air and the heat-conducting pipe 5. At the same time, the higher the pressure, the faster the water vapor condenses, thereby improving the air drying efficiency. Meanwhile, the water vapor in the air condenses on the outer wall of the heat-conducting pipe 7. Then the dried air is discharged through the air outlet 11. The condensed droplets collect at the bottom of the air duct 6. Then the drain outlet 12 is opened periodically to discharge the condensate through the drain outlet 12.

[0025] A heat storage tank 14 is fixedly connected to the outer wall of the fixed box 1. A liquid pump 15 is installed at the input end of the heat storage tank 14. The liquid inlet of the liquid pump 15 is connected to one side of the heat exchange box 4 through a set of liquid pipes 16. The output end of the heat storage tank 14 is connected to the other side of the heat exchange box 4 through another set of liquid pipes 16.

[0026] This invention uses a liquid pump 15 to pump the heat transfer fluid from the heat exchange box 4 into the heat storage tank 14. At the same time, the heat transfer fluid in the heat storage tank 14 flows back into the heat exchange box 4 under the push of the heat transfer fluid pumped in by the liquid pump 15, thereby realizing the circulation of the heat transfer fluid between the heat exchange box 4 and the heat storage tank 14, and thus absorbing and collecting the heat in the heat transfer pipe 5 in the heat exchange box 4 into the heat storage tank 14.

[0027] In one instance of this embodiment, please refer to Figures 1-4 The outer wall of the heat-conducting cylinder 7 is fixedly connected with multiple sets of circumferentially distributed heat-conducting fins 13; the present invention increases the contact area between air and cold source by setting multiple sets of heat-conducting fins 13, thereby improving the equipment's efficiency in absorbing heat from the air.

[0028] In one instance of this embodiment, please refer to Figures 1-4 The installation box 3 is equipped with a filter assembly connected to the heat conduction cylinder 7 for filtering the refrigerant gas in the heat conduction cylinder 7. The filter assembly includes a return box 17 fixedly installed in the installation box 3. The return box 17 is fixedly connected to the heat conduction cylinder 7. A centrifugal pump 18 is fixedly installed in the installation box 3 on one side of the return box 17. The outlet end of the centrifugal pump 18 is fixedly connected to the heat conduction cylinder 7. The return box 17 and the inlet end of the centrifugal pump 18 are connected by a connecting pipe 19. A filter element 20 is installed in the return box 17.

[0029] This invention first uses a centrifugal pump 18 to pump the refrigerant gas in the reflux box 17 into the heat transfer cylinder 7 along the connecting pipe 19. At the same time, the gas pressure in the reflux box 17 decreases, and the refrigerant gas in the heat transfer cylinder 7 flows into the reflux box 17. During this process, the refrigerant gas is filtered by the filter element 20. With the circulation of the refrigerant gas in the heat transfer cylinder 7, the refrigerant in the pipeline is filtered.

[0030] The working principle of this invention is as follows: During operation, the compressor 9 first starts, and the room-temperature high-pressure refrigerant liquid in the heat-conducting pipe 5 flows into the capillary tube 8 under the pumping force of the compressor 9. Then, when the room-temperature high-pressure refrigerant liquid enters the heat-conducting cylinder 7 through the capillary tube 8, it changes from a high flow rate to a low flow rate, resulting in a significant pressure drop. This pressure drop lowers the boiling point of the refrigerant liquid and causes it to begin evaporating and absorbing heat, producing low-temperature refrigerant vapor. Finally, the low-temperature refrigerant vapor flows into the heat-conducting cylinder 7. The low-temperature refrigerant vapor in the heat-conducting cylinder 7 then absorbs heat from the airflow and is converted into room-temperature refrigerant vapor. This room-temperature refrigerant vapor is then compressed by the compressor 9 to form a high-temperature refrigerant liquid. The high-temperature refrigerant liquid enters the heat-conducting pipe 5 along the first connecting pipe 19, thereby absorbing heat from the gas entering the air duct 6 through the air inlet 10. Furthermore, this invention uses a centrifuge to compress and inject air into the air duct. Inside the air duct 6, high-pressure air is formed. The high-pressure air is compressed and its temperature rises. At this time, the temperature difference between the air and the heat-conducting cylinder 5 is greater, thereby increasing the heat exchange rate between the air and the heat-conducting cylinder 5. At the same time, the higher the pressure, the faster the water vapor condenses, thereby improving the air drying efficiency. Meanwhile, the water vapor in the air condenses on the outer wall of the heat-conducting cylinder 7. Then, the dried air is discharged through the air outlet 11. The condensed droplets collect at the bottom of the air duct 6. Then, the drain outlet 12 is opened periodically to discharge the condensate. At the same time, the present invention uses the liquid pump 15 to pump the heat-conducting liquid in the heat exchange box 4 of the heat storage tank 14 into the heat storage tank 14. Simultaneously, the heat-conducting liquid in the heat storage tank 14 is pushed back into the heat exchange box 4 by the heat-conducting liquid pumped in by the liquid pump 15, thereby realizing the circulation of heat-conducting liquid between the heat exchange box 4 and the heat storage tank 14, thereby absorbing and collecting the heat in the heat-conducting pipe 5 in the heat exchange box 4 into the heat storage tank 14.
