Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, and more specifically, to a large-diameter heat exchange device for a ground source heat pump. Background Technology

[0002] Utilizing heat pump technology to extract low-grade heat energy from sewage or surface water for building heating and air conditioning, i.e., sewage or surface water source heat pump heating and air conditioning systems, has enormous energy-saving potential, with energy savings of over 45%. Based on my country's current sewage discharge, the development and utilization of low-grade heat energy from sewage (assuming a temperature drop of 4-5℃) could provide heating and air conditioning for 20% of urban buildings. Its development and application prospects are very broad, and it is one of the effective ways to achieve energy conservation and emission reduction in buildings.

[0003] Traditional ground source heat pump heat exchangers typically place the ground source heat pump and heat pipes inside the soil. However, the soil is in constant contact with the heat pipes, which can easily corrode them, causing damage and breakage. This damage affects the normal operation of the heat pipes and significantly reduces the efficiency of the system. Furthermore, since the heat pipes are buried in the soil, it is impossible to monitor their condition in a timely manner, further impacting the system's performance.

[0004] To address the aforementioned issues, utility model publication CN218884303U discloses a ground source heat pump heat exchange device. This device utilizes a protective sleeve in conjunction with a heat-conducting pipe. A protective sleeve is added to the outer edge of the heat-conducting pipe, and then a first annular sleeve and a second annular sleeve are used to clamp the protective sleeve. Finally, a cylinder and a spring are used to assist in damping the heat-conducting pipe. Compared to traditional devices, this device protects the heat-conducting pipe, preventing direct contact between soil and the heat-conducting pipe, which could cause corrosion and affect its performance.

[0005] When the above-mentioned ground source heat pump heat exchange device is used in actual use, the water source heat pump system directly exchanges heat with groundwater or surface water. The water may contain impurities, particulate matter or corrosive substances. Impurities may gradually accumulate in the pipes during the circulation process, causing pipe blockage. At the same time, it will cause wear or corrosion to the internal equipment and shorten the service life of the equipment. Utility Model Content

[0033] 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.

[0034] This application discloses a ground source heat pump large-diameter heat exchange device, including a filter shell 1, and a filter assembly is installed inside the filter shell 1.

[0035] The filter assembly includes a motor 2, with a rotating rod 3 mounted on the output end of the motor 2. Three fixed rods 4 are fixedly connected to the outside of the rotating rod 3. A scraper 5 is fixedly connected to one end of each of the three fixed rods 4. A return spring 6 is mounted on the outside of each of the three fixed rods 4. A sliding ring 7 is mounted on one end of each of the three return springs 6. A filter barrel 8 is mounted on the outside of the three fixed rods 4 and the scraper 5. Multiple filter holes 9 are opened on the surface of the filter barrel 8. Support rings 10 are fixedly connected to the outside of both ends of the filter barrel 8. The rotating rod 3 is driven by the motor 2 to rotate. The rotating rod 3 drives the scraper 5 to scrape the inner wall of the filter barrel 8 through the three fixed rods 4. This scrapes off impurities on the inner wall of the filter barrel 8, preventing blockage of the filter holes 9. At the same time, it can filter water. The multiple filter holes 9 can filter the water, which helps to improve the quality of the water source and facilitates better heat exchange. The three fixed rods 4 move inside the sliding ring 7, which allows the three scraper 5 to extend and retract during scraping, making it easier to fit the inner wall of the filter barrel 8. The three return springs 6 can then return the scraper 5 to its original position, allowing for repeated scraping.

[0036] Reference Figure 1As shown, the top left side of the filter housing 1 is connected to a first water supply pipe 11, the bottom of the filter housing 1 is connected to a first drain pipe 12, the right side of the filter housing 1 is connected to a second water supply pipe 13, and one end of the second water supply pipe 13 is connected to the outer shell 14. Water can be transported to the inside of the filter housing 1 through the first water supply pipe 11, and the filtered impurities and particles can be discharged through the first drain pipe 12. The filtered water will be transported to the inside of the outer shell 14 for heat exchange through the second water supply pipe 13.

[0037] Reference Figure 5 As shown, two support plates 15 are installed at the bottom of the outer casing 14. Each support plate 15 has three grooves 16 inside. Each groove 16 has a telescopic spring 17 installed inside. Each telescopic spring 17 has a support column 18 installed at its top. Each groove 16 has a sliding groove 19 installed inside. Each support plate 15 has a base 20 installed at its bottom. Each base 20 has two rubber buffer columns 21 fixedly connected inside. The three sliding grooves 19 can support the support columns 18 to slide inside the grooves 16 and press down on the telescopic springs 17. At the same time, the two support plates 15 move downward to press down on the rubber buffer columns 21, which can buffer the impact and shaking of the water flow on the outer casing 14 during heat exchange, which helps to maintain the stability of the inner casing 14 and increases the stability of the equipment inside the outer casing 14.

[0038] Reference Figure 6 As shown, a heat exchange tube 22 is installed inside the outer casing 14, a drain pipe 23 is connected to the bottom of the outer casing 14, a second drain pipe 24 is connected to the right side of the outer casing 14, and a flange 25 is installed at the right end of the second drain pipe 24. The water that has completed heat exchange will be discharged through the second drain pipe 24. The flange 25 can be used to connect the second drain pipe 24 to the water pipe, which can effectively prevent water from spraying.

[0039] Working principle of this utility model: This utility model designs a large-diameter heat exchange device for a ground source heat pump, as shown in the attached instruction manual for its specific structure. Figure 1-6As shown, in this technical solution, through the cooperation of various structures, water is first transported to the inside of the filter shell 1 through the first water supply pipe 11. Then, the motor 2 is started, and the motor 2 drives the rotating rod 3 to rotate. The rotation of the rotating rod 3 drives the three fixed rods 4 to rotate. The three fixed rods 4 drive the scraper 5 to stir and scrape inside the filter barrel 8, which facilitates the scraping of impurities in the water from the filter holes 9, preventing impurities and particles in the water from clogging the filter holes 9. At the same time, the water can be filtered through multiple filter holes 9. When the three scraper 5 encounters solid objects while scraping, the fixed rods 4 move inside the sliding ring 7, allowing the scraper 5 to retract. Then, the return spring 6 returns the scraper 5 to its original position. Subsequently, the three scraper 5 can scrape the device on the inner wall of the filter barrel 8 to the bottom of the filter shell 1. Then, the impurities can be discharged through the first drain pipe 12. After the water has been drained and cleaned, it will be transported to the inside of the outer shell 14 through the second water supply pipe 13. Then, it will undergo heat exchange inside the heat exchange pipe 22. After the heat exchange is completed, the water will be discharged through the second drain pipe 24. The sewage pipe 23 can discharge the wastewater from the heat exchange. When the water causes the outer shell 14 to shake during heat exchange, the multiple support columns 18 at the bottom of the outer shell 14 can slide downwards by sliding inside the slide groove 19, thereby squeezing the multiple telescopic springs 17, which can buffer the impact of the water flow on the shaking of the outer shell 14. At the same time, the two support plates 15 squeeze the rubber buffer column 21 downwards, which can keep the outer shell 14 stable.
