Description

Technical Field

[0001] This application relates to the field of cold storage technology, and in particular to an improved device and method based on traditional cold storage. Background Technology

[0002] Currently, cold storage is a type of refrigeration equipment that refers to an environment created artificially with different temperatures or humidity than the outside world. It is a constant temperature and humidity storage device for items such as food, liquids, chemicals, pharmaceuticals, vaccines, and scientific experiments. Cold storage mainly consists of an outdoor unit and an indoor unit. The indoor unit is installed inside the cold storage, while the outdoor unit is installed in the control room. When the indoor unit is working, it converts high-temperature (65~90℃) and high-pressure (10~18 bar) dry saturated Freon vapor. The high-temperature and high-pressure dry saturated Freon vapor is converted back into high-pressure, low-temperature, subcooled Freon liquid by the outdoor unit. The high-pressure, low-temperature, subcooled Freon liquid re-enters the indoor unit for heat exchange, thereby achieving the refrigeration effect of the cold storage.

[0003] In existing technologies, power equipment such as compressors and condensers are placed outdoors, generating loud noise during operation, which leads to complaints from nearby residents, fails to meet environmental protection requirements, affects the social image of enterprises, and the complex outdoor working conditions will accelerate the aging of equipment, resulting in a high failure rate and high maintenance costs.

[0004] Therefore, there is an urgent need for a cold storage equipment that can reduce equipment aging and failure rate, and improve the operational stability of cold storage equipment. Summary of the Invention

[0005] To improve the operational stability of cold storage equipment, this application provides an improved device and method based on traditional cold storage.

[0006] Firstly, this application provides an improved device based on a traditional cold storage facility, employing the following technical solution: An improved device based on a traditional cold storage includes a main body comprising a storage chamber and two cold storage units. The two cold storage units are located inside the storage chamber and on opposite sides of its length. Each side of the storage chamber has a first entrance door, and the opposite side of each cold storage unit has a second entrance door. The first and second entrance doors face each other. A circulating air assembly is located between the two cold storage units. Several water-cooling assemblies are also located between the two cold storage units, arranged along the width of the storage chamber. Several compressors are located between the two cold storage units, on opposite sides of the water-cooling assemblies along the length of the storage chamber. One end of each compressor is connected to a cold storage unit, and the other end is connected to the upper end of a water-cooling assembly. An air inlet pipe connects the cold storage unit to the water-cooling assembly, allowing cold air from the water-cooling assembly to enter the cold storage unit through the air inlet pipe.

[0007] By adopting the above technical solution, the cold storage unit houses two cold storage rooms. When it is necessary to enter the cold storage room, the operator enters through the first entrance door and the second entrance door respectively. The cold storage room is made of sound insulation and heat insulation materials. During operation, the compressor extracts the gas inside the cold storage room and processes it under high temperature and pressure. The high-temperature and high-pressure gas is then transported to the water-cooling components, which cool the gas and return it to the cold storage room through the air inlet pipe. Since the water-cooling components are located inside the cold storage unit, the temperature inside the cold storage room will rise. The circulating air components extract the gas inside the cold storage room, and the gas outside the cold storage room enters the cold storage room, thereby cooling the inside of the cold storage room. This equipment adopts a combination of water cooling and air cooling structure, using air convection to dissipate the heat carried by the water-cooling components into the environment, thus improving the operational stability of the cold storage equipment.

[0008] Optionally, the circulating air assembly includes several fans and a temperature sensor. The temperature sensor is fixedly connected inside the silo and located between the two cold storage units. Several fans are fixedly connected to one side of the upper end of the silo along the width direction and located between the two cold storage units. An air inlet is opened on the side of the silo away from the fans.

[0009] By adopting the above technical solution, the temperature sensor detects the temperature inside the chamber. When the temperature is higher than 28°C, the fan is activated to extract the hot gas from the chamber, and external air enters the chamber through the air inlet. When the temperature is lower than 26°C, the fan stops working, which improves the convenience of air circulation inside the chamber.

[0010] Optionally, a baffle plate is fixed inside the cold storage unit. The baffle plate is located between the two cold storage units and on the side of the cold storage unit closest to the air inlet. The baffle plate is inclined from top to bottom along the direction of the baffle plate pointing towards the fan.

[0011] By adopting the above technical solution, when outside air enters the chamber, it first comes into contact with the baffle plate, moves downward, and first comes into contact with the water-cooling components at the bottom of the chamber, and then moves upward, so that the water-cooling components can better contact the outside air and improve the air convection effect inside the chamber.

[0012] Optionally, the water-cooled assembly includes a water tank, a water pump, a sprayer, a base, several finned tubes, and a cleaning component. The base is fixedly connected inside the silo and located between two cold storage units. Several finned tubes are fixedly connected vertically to the upper end of the base and arranged along the length of the silo. Both the finned tubes and the base are hollow and connected. The air inlet pipe is connected to the base. The compressor is connected to the upper end of the finned tubes. The water tank and water pump are fixedly connected to the upper end of the silo. The sprayer is fixedly connected inside the silo and located directly above the base. One end of the water pump is connected to the water tank, and the other end of the water pump passes through the silo and is connected to the sprayer. The cleaning component is connected to the base and is used to clean the surface of the finned tubes.

[0013] By adopting the above technical solution, the base supports several finned tubes. When high-temperature and high-pressure gas is introduced into the finned tubes, the water pump draws water from the water tank and delivers it to the sprayer. The sprayer sprays water out and cools the finned tubes. The cooled gas moves downward into the base. The cold air in the base is delivered to the cold storage through the air inlet pipe. The cleaning component cleans the finned tubes, improving the convenience of cooling high-temperature and high-pressure gas.

[0014] Optionally, the lower end of the storage unit has several drainage outlets located between the two cold storage units, and a water collection tank is fixed at the lower end of the storage unit, with the water collection tank facing the drainage outlets.

[0015] By adopting the above technical solution, the water inside the tank passes through the drain outlet and is collected in the water collection tank, which improves the convenience of wastewater treatment inside the tank.

[0016] Optionally, the cleaning components include a waterproof motor, a lead screw, a connecting plate, several scraper rings, several scraper blades, and several return springs. The waterproof motor is vertically fixed to one side of the base along the width of the silo. The lead screw is coaxially fixed to the output shaft of the waterproof motor. The lead screw passes through the connecting plate and is threadedly connected to the connecting plate. Each scraper ring corresponds to a finned tube. The scraper ring is sleeved on the outside of the finned tube and is slidably connected to the finned tube vertically. Each scraper ring is fixedly connected to the connecting plate. Each scraper ring cooperates with two scraper blades. The two scraper blades are located on both sides of the scraper ring along the width of the silo. The scraper blades are slidably connected to the scraper ring along the width of the silo. Each scraper blade corresponds to a return spring. The return spring is located between the scraper blade and the scraper ring. In its natural state, the return spring drives the scraper blade to move closer to the finned tube.

[0017] By adopting the above technical solution, when it is necessary to clean the finned tube, the waterproof motor drives the lead screw to rotate, and the waterproof motor and lead screw drive the connecting plate to move upward, which in turn drives the scraper ring to move upward. The scraper ring cleans the side of the finned tube. When the scraper ring moves to the upper end of the finned tube, the reset spring resets and drives the scraper to move closer to the finned tube. The scraper cleans the upper end face of the finned tube, which improves the convenience of cleaning the finned tube.

[0018] Optionally, scraper plates are provided on both sides of the finned tube along the length of the silo body. The scraper plates are located at the upper end of the base and are slidably connected to the base along the length of the base. When the scraper ring is located at the upper end of the finned tube, the scraper plate is located on the side of the upper end of the base away from the waterproof motor. A guide rod is provided between the scraper ring and the scraper plate. One end of the guide rod is hinged to the scraper plate, and the other end of the guide rod is hinged to the side of the scraper ring away from the waterproof motor. When the scraper ring moves down, the guide rod pushes the scraper plate closer to the waterproof motor.

[0019] By adopting the above technical solution, during the upward movement of the scraper ring, the scraper ring and the guide rod work together to drive the scraper plate away from the waterproof motor, and the scraper plate cleans the upper part of the base, which improves the convenience of cleaning the base.

[0020] Secondly, this application provides an improved method based on traditional cold storage, comprising the following steps: S1: The compressor extracts gas from the cold storage and processes the gas at high temperature and high pressure. S2: The sprayer sprays water from the tank to cool the finned tubes. S3: The temperature sensor detects the temperature inside the chamber. When the temperature is higher than 28°C, the fan is activated to extract the hot gas from the chamber. S4: The fan stops working when the temperature is below 26 degrees Celsius; S5: The cleaning component cleans the surface of the finned tube, and the scraper cleans the surface of the base; S6: Wastewater flows through the drain outlet into the collection tank for recycling.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. When it is necessary to enter the cold storage, the operator enters the cold storage through the first entrance door and the second entrance door respectively. The cold storage is made of sound insulation and heat insulation materials. During the operation of the cold storage, the compressor extracts the gas in the cold storage and processes the gas at high temperature and high pressure. The high temperature and high pressure gas is sent to the water cooling component, which cools the high temperature and high pressure gas and returns it to the cold storage through the air inlet pipe. Since the water cooling component is located inside the compartment, it will cause the temperature inside the compartment to rise. The circulating air component extracts the gas inside the compartment, and the gas outside the compartment enters the compartment, thereby cooling the inside of the compartment. This equipment adopts a combination of water cooling and air cooling structure, and uses air convection to dissipate the heat carried by the water cooling component into the environment, which improves the stability of the cold storage equipment operation. 2. Temperature sensors detect the temperature inside the chamber. When the temperature is higher than 28°C, the fan is activated to extract the hot gas from the chamber, and outside air enters the chamber through the air inlet. When the temperature is lower than 26°C, the fan stops working, which improves the convenience of air circulation inside the chamber. 3. When cleaning the finned tube is required, the waterproof motor drives the lead screw to rotate. The waterproof motor and lead screw drive the connecting plate to move upward, which in turn drives the scraper ring to move upward. The scraper ring cleans the side of the finned tube. When the scraper ring moves to the upper end of the finned tube, the return spring resets and drives the scraper to move closer to the finned tube. The scraper cleans the upper end face of the finned tube. During the upward movement of the scraper ring, the scraper ring and guide rod work together to drive the scraper plate away from the waterproof motor. The scraper plate cleans the upper end of the base, improving the convenience of cleaning the finned tube and the base. Attached Figure Description

[0028] This application discloses an improved device based on a traditional cold storage facility. Example

[0029] Reference Figure 1 and Figure 2An improved device based on traditional cold storage includes a main body 1, which comprises a storage chamber 11 and two cold storage units 12.

When access to a cold storage unit 12 is required, the operator enters through the first entrance door 13 and the second entrance door 14 respectively.

[0030] Reference Figure 2 and Figure 3 Multiple water-cooled components 3 are arranged between two cold storage units 12, along the width of the storage unit 11. Multiple compressors 15 are also located between the two cold storage units 12, situated on either side of the water-cooled components 3 along the length of the storage unit 11. One end of each compressor 15 is connected to a cold storage unit 12, and the other end is connected to the upper part of the water-cooled components 3. During operation, the compressors 15 extract gas from the cold storage unit 12 and process it under high temperature and pressure. The high-temperature, high-pressure gas is then transported to the interior of the water-cooled components 3. An air inlet pipe 16 is provided between the cold storage unit 12 and the water-cooled components 3. The water-cooled components 3 cool the high-temperature, high-pressure gas and return it to the interior of the cold storage unit 12 through the air inlet pipe 16.

[0031] Reference Figure 2 and Figure 3 The water-cooled assembly 3 includes a water tank 31, a water pump 32, a sprayer 33, a base 34, multiple finned tubes 35, and a cleaning component 4. The base 34 is fixedly connected to the inside of the silo 11 and is located between the two cold storage units 12. Multiple finned tubes 35 are fixedly connected vertically to the upper end of the base 34 and arranged along the length of the silo 11. Both the finned tubes 35 and the base 34 are hollow and connected. The compressor 15 is connected to the upper end of the finned tubes 35, and the air inlet pipe 16 is connected to the base 34. The base 34 supports the multiple finned tubes 35. High-temperature and high-pressure gas is introduced into the finned tubes 35. The cooled gas moves downward to the inside of the base 34 and passes through the air inlet pipe 16 into the inside of the cold storage unit 12.

[0032] Reference Figure 2The water tank 31 and the water pump 32 are both fixedly connected to the upper end of the silo body 11. The sprayer 33 is fixedly connected to the inside of the silo body 11 and located directly above the base 34. One end of the water pump 32 is connected to the water tank 31, and the other end of the water pump 32 passes through the silo body 11 and is connected to the sprayer 33. When high-temperature and high-pressure gas is introduced into the finned tube 35, the water pump 32 draws water from the water tank 31 and delivers it to the sprayer 33. The sprayer 33 sprays water and cools the finned tube 35. The cooled gas moves downward to the inside of the base 34. The cold air in the base 34 is delivered to the inside of the cold storage 12 through the air inlet pipe 16.

[0033] Reference Figure 1 and Figure 2 Multiple drain outlets 17 are opened at the lower end of the silo body 11. The multiple drain outlets 17 are located between the two cold storage rooms 12. A water collection tank 18 is fixed at the lower end of the silo body 11. The water collection tank 18 is directly opposite the drain outlets 17. Water in the silo body 11 passes through the drain outlets 17 and is collected in the water collection tank 18, which improves the convenience of wastewater treatment inside the silo body 11.

[0034] Reference Figure 3 The cleaning component 4 is connected to the base 34 and is used to clean the surface of the finned tube 35. The cleaning component 4 includes a waterproof motor 41, a lead screw 42, a connecting plate 43, multiple scraper rings 44, multiple scraper blades 45, and multiple return springs 46. The waterproof motor 41 is fixedly connected vertically to one side of the base 34 along the width direction of the compartment 11. The lead screw 42 is fixedly connected coaxially to the output shaft of the waterproof motor 41. The lead screw 42 passes through the connecting plate 43 and is threadedly connected to the connecting plate 43. The waterproof motor 41 and the lead screw 42 cooperate to drive the connecting plate 43 to move vertically. Each scraper ring 44 corresponds to a finned tube 35. The scraper ring 44 is sleeved on the outside of the finned tube 35 and is slidably connected to the finned tube 35 vertically. Multiple scraper rings 44 are fixedly connected to the connecting plate 43. During the vertical movement of the connecting plate 43, the connecting plate 43 drives the scraper rings 44 to move, and the scraper rings 44 clean the sides of the finned tube 35.

[0035] Reference Figure 3A scraper ring 44 is paired with two scraper blades 45, which are located on both sides of the scraper ring 44 along the width of the chamber 11. The scraper blades 45 are slidably connected to the scraper ring 44 along the width of the chamber 11. Each scraper blade 45 corresponds to a return spring 46, which is located between the scraper blade 45 and the scraper ring 44. One end of the return spring 46 is fixedly connected to the scraper ring 44, and the other end is fixedly connected to the scraper blade 45. In its natural state, the return spring 46 is in a stretched state. When the scraper ring 44 moves to the upper end of the finned tube 35, the return spring 46 resets and drives the scraper blade 45 to move closer to the finned tube 35. The scraper blade 45 cleans the upper surface of the finned tube 35. The upper end of the finned tube 35 is inclined and adapted to the scraper blade 45. When the scraper ring 44 moves downward, the finned tube 35 guides the scraper blade 45, causing the scraper blade 45 to move away from the finned tube 35, which improves the convenience of cleaning the finned tube 35.

[0036] Reference Figure 3 The finned tube 35 is provided with scraper plates 47 on both sides along the length of the silo body 11. The scraper plates 47 are located at the upper end of the base 34 and are slidably connected to the base 34 along the length of the base 34. A guide rod 48 is provided between the scraper ring 44 and the scraper plate 47. One end of the guide rod 48 is hinged to the scraper plate 47, and the other end of the guide rod 48 is hinged to the side of the scraper ring 44 away from the waterproof motor 41. The guide rod 48 is inclined from top to bottom along the direction of the scraper ring 44 pointing to the connecting plate 43. During the upward movement of the scraper ring 44, the scraper ring 44 and the guide rod 48 work together to drive the scraper plate 47 to the side away from the waterproof motor 41. The scraper plate 47 cleans the upper end of the base 34.

[0037] Reference Figure 1 and Figure 4 A circulating air assembly 2 is installed between the two cold storage units 12. Since the water-cooling assembly 3 is located inside the storage unit 11, the temperature inside the storage unit 11 will rise. The circulating air assembly 2 extracts the gas inside the storage unit 11, and the gas outside the storage unit 11 enters the storage unit 11, thereby cooling the inside of the storage unit 11. The circulating air assembly 2 includes multiple fans 21 and a temperature sensor 22. The temperature sensor 22 is fixedly connected inside the storage unit 11 and located between the two cold storage units 12. The multiple fans 21 are fixedly connected to one side of the upper end of the storage unit 11 along the width direction and located between the two cold storage units 12. An air inlet 23 is opened on the side of the storage unit 11 away from the fans 21. The temperature sensor 22 detects the temperature inside the storage unit 11. When the temperature is higher than 28°C, the fans 21 are activated, and the fans 21 extract the hot gas inside the storage unit 11. The outside air enters the storage unit 11 through the air inlet 23. When the temperature is lower than 26°C, the fans 21 stop working.

[0038] Reference Figure 4Inside the silo 11, a baffle plate 24 is fixedly installed. The baffle plate 24 is located between the two cold storage units 12 and on the side of the silo 11 near the air inlet 23. The baffle plate 24 is inclined from top to bottom along the direction pointing towards the fan 21. When outside air enters the silo 11, it first contacts the baffle plate 24. The air moves downward and first contacts the water-cooling component 3 at the bottom of the silo 11, and then moves upward, so that the water-cooling component 3 can better contact the outside air and improve the air convection effect inside the silo 11.

[0039] The implementation principle of an improved device based on a traditional cold storage in this application embodiment is as follows: When it is necessary to enter the cold storage 12, the operator enters the cold storage 12 through the first entrance door 13 and the second entrance door 14 respectively. The cold storage 12 is made of sound insulation and heat insulation material. During the operation of the cold storage 12, the compressor 15 extracts the gas inside the cold storage 12 and processes the gas under high temperature and high pressure. The high temperature and high pressure gas is then transported to the water-cooling component 3, where the water-cooling component 3 cools the high temperature and high pressure gas and returns it to the cold storage 12 through the air inlet pipe 16. The cooling component 3 is installed inside the chamber 11, which will cause the temperature inside the chamber 11 to rise. The temperature sensor 22 detects the temperature inside the chamber 11. When the temperature is higher than 28°C, the fan 21 is started. The fan 21 extracts the hot gas from the chamber 11, and the outside air enters the chamber 11 through the air inlet 23. When the temperature is lower than 26°C, the fan 21 stops working. The equipment adopts a combination of water cooling and air cooling structure. It uses air convection to dissipate the heat carried by the water cooling component 3 into the environment, which improves the stability of the cold storage 12 equipment operation.

[0040] This application also discloses an improved method based on a traditional cold storage 12, comprising the following steps: S1: Compressor 15 extracts gas from cold storage 12 and processes the gas at high temperature and high pressure. S2: The sprayer 33 sprays water from the water tank 31 to cool the finned tube 35. S3: Temperature sensor 22 detects the temperature inside chamber 11. When the temperature is higher than 28°C, fan 21 is started to extract the hot gas inside chamber 11. S4: When the temperature is below 26 degrees Celsius, fan 21 stops working; S5: Cleaning component 4 cleans the surface of finned tube 35, and scraper 47 cleans the surface of base 34; S6: Wastewater flows through the drain outlet 17 into the water collection tank 18 for recycling.

[0041] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application.
