Description

Technical Field

[0001] This invention relates to the field of building technology, specifically to a building heat recovery and energy storage type water source heat pump. Background Technology

[0002] Water source heat pumps utilize low-grade heat energy resources formed by absorbing solar and geothermal energy from shallow water sources on the Earth's surface, such as groundwater, rivers, and lakes. They employ the heat pump principle and transfer low-grade heat energy to high-grade heat energy through a small amount of high-grade electrical energy input.

[0003] In the prior art, Chinese utility model publication CN222012358U discloses a water source heat pump unit with energy storage, including a housing. The housing integrates a water source heat pump unit, an integrated operation control logic module, and an energy storage tank. The water source heat pump unit includes an evaporator, a four-way valve, a compressor, a condenser, and an expansion valve. The four-way valve connects to the evaporator, compressor, and condenser respectively. A cooling return water pipe is provided on the condenser, with one end connected to the condenser and the other end connected to the energy storage tank. A cooling side circulation pipe is provided on the energy storage tank, with one end connected to the energy storage tank and the other end having two pipes: a cooling water supply pipe and an air conditioning bypass water supply pipe. The cooling water supply pipe is connected to the condenser, and the air conditioning bypass water supply pipe is connected to the evaporator.

[0004] The water source for existing water source heat pumps is drawn directly from wells. Water drawn from wells contains many impurities. Due to temperature changes, some water-soluble impurities precipitate out of the water and then condense in the pipes. In mild cases, this reduces the water flow; in severe cases, it can cause blockage of the water pipes, increase the operating power of the water pump, and thus affect the normal operation of the entire water source heat pump system.

[0051] Please see Figures 1 to 14 This invention provides a technical solution: a building heat recovery energy storage water source heat pump, comprising:

When the water is transported to the filter box 4 between water supply pipe 3 and water inlet pipe 5, the filter components inside the filter box 4 can filter impurities in the water and prevent impurities from entering the body 2 of the heat recovery and energy storage water source heat pump.

[0056] The cleaning component is set up to remove impurities filtered out by the filter component, preventing them from clogging the filter holes and affecting the efficiency of subsequent water delivery and filtration. Example 2:

[0064] By cooperating with the mounting plate 6 and the mounting groove 8, at least one set of filter plates 9 are installed inside the filter box 4 to filter the water delivered to the heat recovery energy storage water source heat pump body 2.

[0065] The impurity discharge port 11 and the first channel 16 are provided to clean the impurities filtered out by the filter plate 9 and prevent the impurities from accumulating on the filter plate 9 for a long time, which would affect the filtration efficiency of the filter plate 9. The cover plate 7 is provided to cover the outlet end of the impurity discharge port 11 and store the impurities discharged from the impurity discharge port 11. Example 3:

[0066] like Figures 4-10 As shown, the building heat recovery energy storage water source heat pump disclosed in Embodiment 3 of the present invention has a structure that is basically the same as that in Embodiment 2, except that:

[0067] A through hole 22 is provided at the center of the filter plate 9. A rotating shaft 13 is rotatably installed inside the through hole 22. A motor 12 is installed at the lower end of the filter plate 9 corresponding to the end position of the rotating shaft 13. The output end of the motor 12 is connected to the end of the rotating shaft 13.

[0068] A connecting plate 15 is installed on the outer surface of the rotating shaft 13 at a position corresponding to the upper surface of the filter plate 9. A first storage groove 20 is opened on the lower end face of the connecting plate 15. A lever 18 is inserted into the first storage groove 20, and a first return spring 21 is provided between the side wall of the lever 18 and the inner wall of the first storage groove 20.

[0069] The lever 18 is provided with a first clearance groove 19 at the position of the multi-layer spiral rib on the same side of the vortex guide plate 14.

[0070] The vortex guide plate 14 has a reset groove 17 on each of the multi-layer spiral ribs corresponding to the first through groove 16. The width of the reset groove 17 is greater than the thickness of the lever plate 18.

[0071] The dial plate 18 has a second storage groove 28 on the side facing the rotating shaft 13, and a compensation plate 32 is provided inside the second storage groove 28.

[0072] The second storage slot 28 has a first guide slot 29 at a position corresponding to the compensation plate 32. A first guide block 31 is slidably disposed inside the first guide slot 29, and the first guide block 31 is connected to the compensation plate 32.

[0073] A second return spring 30 is provided between the first guide block 31 and the first guide groove 29. One side wall of the compensation plate 32 is always in contact with the surface of the rotating shaft 13 through the cooperation of the first guide block 31 and the second return spring 30.

[0074] Through the cooperation of motor 12 and rotating shaft 13, the connecting plate 15 is driven to rotate. When the connecting plate 15 rotates, it drives the deflector plate 18 to rotate along the spiral direction of the vortex guide plate 14. During the rotation, the impurities filtered out by the filter plate 9 are deflected, causing the impurities to move along the rotation direction of the vortex guide plate 14. With the cooperation of reset groove 17 and first clearance groove 19, the deflector plate 18 rotates one revolution and pushes the impurities to move along the rotation direction of the vortex guide plate 14 by the distance between the adjacent two sets of spiral ribs. Finally, the impurities are discharged into the cover plate 7 through the first through groove 16. Example 4:

[0075] like Figures 9-14 As shown, the building heat recovery energy storage water source heat pump disclosed in Embodiment 4 of the present invention has a structure that is basically the same as that in Embodiment 3, except that:

[0076] The lever 18 has multiple sets of spaced third storage slots 33 near the filter plate 9. Each third storage slot 33 has an impact plate 34 inserted inside it, and a third return spring 35 is provided between the impact plate 34 and the third storage slot 33.

[0077] The third storage slot 33 has a second guide slot 36 inside, and a second guide block 37 is provided inside the second guide slot 36. The second guide block 37 is connected to the side wall of the impact plate 34.

[0078] The rotating shaft 13 has a receiving hole 23 at the position corresponding to the through hole 22, and a support rod 24 is provided inside the receiving hole 23;

[0079] The receiving hole 23 is provided with a second clearance groove 39 that penetrates the outer wall of the rotating shaft 13 at the position corresponding to the through hole 22, and a limiting block 40 is provided inside the second clearance groove 39. The limiting block 40 is connected to the surface of the abutment rod 24.

[0080] A limiting groove 41 is formed on the inner wall of the through hole 22 at the position corresponding to the limiting block 40, and a second through groove 42 is formed between the first and last ends of the limiting groove 41.

[0081] A first air-storing bladder 25 is provided between the top of the supporting rod 24 and the top of the receiving hole 23, and a first exhaust pipe 26 is provided inside the rotating shaft 13 at the position corresponding to the first air-storing bladder 25.

[0082] A second air-storing bladder 38 is provided between the second guide block 37 and the second guide groove 36, and a second connecting pipe 27 is provided inside the lever 18 at the position corresponding to the second air-storing bladder 38.

[0083] One end of the first exhaust pipe 26 is connected to the first air storage bag 25, and one end of the second connecting pipe 27 is connected to the second air storage bag 38. A flexible hose is provided between the second connecting pipe 27 and the first exhaust pipe 26.

[0084] When the shaft 13 rotates, the limiting block 40 inserted inside the limiting groove 41 will rise along the trajectory of the limiting groove 41. After rising to a certain height, it will slide down through the second through groove 42. During the rise of the limiting block 40, the holding rod 24 compresses the first air storage bladder 25. The gas inside the first air storage bladder 25 is transported to the inside of each second air storage bladder 38 through the cooperation of the first exhaust pipe 26, the hose, and the second connecting pipe 27. Each second air storage bladder 38 expands, driving the impact plate 34 to rise. When the limiting block 40 slides down along the second through groove 42, the impact plate 34 is held down by the action of the third return spring 35. At this time, the impact plate 34 hits the surface of the filter plate 9, and some impurities blocked in the filter holes of the filter plate 9 are shaken off, thereby accelerating the filtration of the filter plate 9.

[0085] Specifically, the installation plate 6 with the filter plate 9 is inserted into the interior of the filter box 4 through the installation groove 8. Then, through the cooperation of the water supply pipe 3 and the water inlet pipe 5, water from the water source is transported to the interior of the heat recovery and energy storage water source heat pump body 2. When the water is transported to the interior of the filter box 4, the filter plate 9 inside the filter box 4 can filter the water and filter out the impurities contained therein, preventing impurities from entering the interior of the heat recovery and energy storage water source heat pump body 2.

[0086] Simultaneously, the motor 12 is started, and the motor 12 drives the connecting plate 15 to rotate through the rotating shaft 13. When the connecting plate 15 rotates, it drives the deflector 18 to rotate along the spiral direction of the vortex guide plate 14. During the rotation, the impurities filtered out by the filter plate 9 are deflected, causing the impurities to move along the rotation direction of the vortex guide plate 14. With the cooperation of the reset groove 17 and the first clearance groove 19, the deflector 18 rotates one revolution and pushes the impurities to move along the rotation direction of the vortex guide plate 14 by the distance between the adjacent two sets of spiral ribs. Finally, the impurities are discharged into the cover plate 7 through the first through groove 16. When cleaning is required, the cover plate 7 can be removed to clean the impurities.

[0087] When the shaft 13 rotates, the limiting block 40 inserted inside the limiting groove 41 will rise along the trajectory of the limiting groove 41. After rising to a certain height, it will slide down through the second through groove 42. During the rise of the limiting block 40, the holding rod 24 compresses the first air storage bladder 25. The gas inside the first air storage bladder 25 is transported to the inside of each second air storage bladder 38 through the cooperation of the first exhaust pipe 26, the hose, and the second connecting pipe 27. Each second air storage bladder 38 expands, driving the impact plate 34 to rise. When the limiting block 40 slides down along the second through groove 42, the impact plate 34 is held down by the action of the third return spring 35. At this time, the impact plate 34 hits the surface of the filter plate 9, and some impurities blocked in the filter holes of the filter plate 9 are shaken off, thereby accelerating the filtration of the filter plate 9.
