[0002] Heat pump technology is an energy-saving device that uses high-level energy to make heat flow from a low-level heat source to a high-level heat source. Heat pumps mainly work on the principle of reverse Carnot cycle. It consumes a part of energy (usually electrical energy) to "extract" the low-grade heat energy stored in the environmental medium (such as water, air, soil, etc.), and upgrades it to high-grade heat energy for heating, cooling or hot water supply. In the industrial field, the wastewater discharged by the industry generally has a certain temperature, and direct discharge will cause a certain amount of waste. However, since the temperature of the wastewater cannot be used directly, people will use heat pump technology to extract the temperature from the industrial wastewater for heating high-temperature water for use in other fields. In the prior art, when using heat pump technology, industrial wastewater will flow through the evaporator and through the surface of the U-shaped tube containing the medium to heat the internal medium. In this process, since there is a large proportion of dirt in the wastewater, this will cause the surface of the U-shaped tube to gradually adhere to dirt, affecting the heat conduction of the evaporator, and then corresponding to the efficiency of the entire heat pump system.

The cooling medium of the gas-liquid separation tank 3 is separated, and the output end of the gas-liquid separation tank 5 is connected to the compressor 6 to compress the cooling medium to form a high temperature and high pressure. A heat exchanger 7 is also installed on the inner side of the frame 1, and the output end of the compressor 6 is connected to the hot inlet port of the heat exchanger 7. The hot outlet port of the heat exchanger 7 flows back to the coolant storage tank 9. A high-temperature water storage tank 8 is arranged inside the frame 1. The cold outlet port of the heat exchanger 7 is connected to the high-temperature water storage tank 8 to store the cold water flowing through the heat exchanger 7 after heating. The cold inlet port of the heat exchanger 7 can be transported into cold water through the pump body, wherein the hot outlet and hot inlet ports of the heat exchanger 7 are high-temperature and high-pressure medium liquid ports, and the cold outlet and cold inlet ports are connection ports for heating water.

[0020] Please refer to Figure 2 , Figure 3 and Figure 6 As shown, a boss 306 is vertically arranged on the inner wall of the evaporator tank 3 on the side away from the U-shaped tube 309, and a mounting plate 307 is symmetrically arranged on the surface of the boss 306. A cleaning mechanism 10 is evenly installed on the surface of the boss 306. A plurality of cleaning mechanisms 10 can be arranged according to the swing amplitude to ensure the cleaning of the surface of the U-shaped tube 309. The cleaning mechanism 10 includes a swing rod 101 rotating between two mounting plates 307 at the same height, and a cross bar 103 is symmetrically arranged on one side of the swing rod 101. The two cross bars 103 are placed parallel to both sides of the U-shaped tube 309, and a brush plate 104 is arranged on the surface of the side where the cross bars 103 are close to each other. The brush plate 104 contacts the surface of the U-shaped tube 309 to clean the surface of the U-shaped tube 309.

[0021] Please refer to Figure 3 and Figure 6 As shown, an incomplete gear 102 is provided on the side of the swing arm 101 away from the cross bar 103. The incomplete gear 102 is concentric with the rotation axis of the swing arm 101. The incomplete gear 102 passes through the surface of the boss 306. A gear rod 20 is vertically slidably installed inside the boss 306. The gear rod 20 is meshed with multiple incomplete gears 102. Then, the movement of the gear rod 20 can be controlled to control the swing of multiple cleaning mechanisms 10, and it is ensured that the multiple cleaning mechanisms 10 are in synchronous motion to prevent collisions.

[0022] Please refer to Figure 2 As shown, a spring 22 is arranged at the lower part of the boss 306, and the top of the spring 22 contacts the lower surface of the gear rod 20. The elastic force of the spring 22 causes the gear rod 20 to always be subjected to an upward force to offset the gravity of the cleaning mechanism 10. When no force is applied, the cleaning mechanism 10 is in a horizontal state, thereby preventing the impeller 12 from having insufficient impact force to drive the operation of the corresponding mechanism.

[0023] Please refer to Figure 2 , Figure 3 and Figure 5 As shown, a through groove 308 is provided above the surface of the boss 306, a fixing bolt B21 is provided above one side of the gear rod 20, and the fixing bolt B21 passes through the through groove 308. A support rod 11 is horizontally provided below the inside of the water inlet pipe 301. The support rod 11 is a rod body spanning below the water inlet pipe 301, and has a small width to reduce the obstruction to the water flow. An impeller 12 is rotatably installed on the upper surface of the support rod 11. The low-temperature wastewater flowing downward through the water inlet pipe 301 will inevitably cause an impact on the impeller 12, so that the impeller 12 rotates. A pulley A13 is provided at the bottom of the impeller 12, and the pulley A13 is placed below the support rod 11. A pulley B14 is rotatably installed on one side of the upper surface of the inside of the evaporator tank 3 close to the boss 306. A transmission belt 15 is sleeved between the pulley B14 and the pulley A13. A toothed disc A16 is provided on the lower surface of the pulley B14. Through the above transmission, the toothed disc A16 can rotate when the wastewater enters, and the toothed disc A16 is horizontally arranged.

[0024] Among them, a gear disc B17 is rotatably installed on the upper side of the inner wall of the evaporator tank 3 close to the boss 306. The gear disc B17 is vertically arranged. The gear disc B17 and the gear disc A16 are vertically arranged and mesh with each other. A fixing bolt A18 is eccentrically arranged on the surface of the gear disc B17. A connecting rod 19 is rotatably installed on the surface of the fixing bolt A18. The end of the connecting rod 19 away from the fixing bolt A18 is hinged on the fixing bolt B21. Since the fixing bolt A18 is in an eccentric state, the gear disc B17 can drive the gear rod 20 to swing back and forth up and down when it rotates.

[0025] Please refer to Figure 2 and Figure 4 As shown, a slide groove 303 is symmetrically opened on the upper part of the water inlet pipe 301, a supporting convex ring 304 is provided on the inner wall of the water inlet pipe 301, a filter plate 305 is installed inside the water inlet pipe 301, the filter plate 305 is placed above the supporting convex ring 304, and protrusions are provided on both sides of the filter plate 305. The protrusions slide inside the slide groove 303 to ensure the stability of the filter plate 305 and prevent it from being offset due to the impact of water flow.

[0026] Please refer to Figure 2 and Figure 7As shown, a stabilizing frame 23 is arranged on the inner wall of the evaporator tank 3, and the stabilizing frame 23 includes a sleeve 231 which is sleeved on the surface of the U-shaped tube 309, and a connecting rod 232 is symmetrically arranged on one side of the sleeve 231, and a connecting plate 233 extends outward from the end of the connecting rod 232, and the two connecting plates 233 are respectively placed on both sides of the boss 306, and the connecting plates 233 are fixed to the inner wall of the evaporator tank 3 by bolts to improve the stability of the U-shaped tube 309 and reduce the impact of water flow impact on it.

[0027] Working principle: When in use, industrial low-temperature wastewater flows into the evaporator tank 3 through the water inlet pipe 301, and heats the medium flowing through the U-shaped tube 309, and then flows out through the water outlet pipe 302 at the bottom. After the medium is heated by the U-shaped tube 309, it is in a low-pressure gas state, and then flows through the gas-liquid separation tank 5 to separate the gas and liquid, and then flows through the compressor 6. After being pressurized by the compressor 6, it forms high temperature and high pressure, and then flows to the heat exchanger 7. At this time, the water flowing through can be heated by the heat exchanger 7 to produce high-temperature water heat, and the medium becomes liquid after releasing heat and flows back to the coolant storage tank 9, thereby forming a circulation system. At the same time, the low-temperature wastewater flows into the evaporator tank 3 through the water inlet pipe 301. When the wastewater is filtered, it can be initially filtered through the filter plate 305 to prevent foreign matter in the wastewater from damaging the U-shaped tube 309, and at the same time drive the impeller 12 to rotate, and then drive the pulley A13 at the bottom to rotate, and the rotation of the pulley A13 drives the toothed disc A16 to rotate, and the toothed disc B17 to rotate through the toothed disc A16. During the rotation of the toothed disc B17, since the fixing bolt A18 is in an eccentric state, it can drive the gear rod 20 to move up and down, and drive the swing rod 101 to swing back and forth within the moving angle by controlling the engagement of the electric box 2 and the incomplete gear 102, so as to clean the dirt attached to the surface of the U-shaped tube 309 through the brush plate 104 to ensure the working efficiency of the system.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
