Description

Technical Field

[0001] The invention belongs to the technical field of heat exchange equipment, and in particular is a high-efficiency heat exchange device for a medium-deep soil source heat pump. Background Art

[0002] A ground source heat pump is a device that uses the relatively stable temperature of the underground soil to complete heat exchange with the interior of the building through a pipe system buried deep around the building. In winter, heat is taken from the soil to heat the building; in summer, heat is discharged to the soil to cool the building. It uses the soil as a heat source or cold source, and uses a high-efficiency heat pump unit to heat or cool the building. When the ground source heat pump device is used for a long time, water needs to circulate in the buried pipes. With the long-term use of the buried pipes, impurities in the water will adhere to the buried pipes, thereby generating scale in the buried pipes. When scale is generated, it will not only reduce the heat exchange effect of the buried pipes, but also reduce the flow rate of the buried pipes. In addition, since the buried pipes are buried in the soil, it is inconvenient to clean the buried pipes. Summary of the invention

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0018] Embodiment 1: Figures 1 to 11 As shown, a medium-deep soil source heat pump high-efficiency heat exchange device described in the present invention includes a soil source heat pump unit 1; the soil source heat pump unit 1 is installed with a water inlet pipe 11 and a water outlet pipe 13; A filter box 2 is provided at the bottom of the water outlet pipe 13; a filter bin 21 is fixedly connected to the filter box 2, and the top of the filter bin 21 is fixedly connected to the filter box 2; there is a gap between the bottom of the filter bin 21 and the bottom of the filter box 2; the water outlet pipe 13 extends into the filter bin 21; A pair of V-shaped plates 22 parallel to each other are fixedly connected to both ends of the filter bin 21; a filter layer 23 is provided between the two pairs of V-shaped plates 22, and the filter layer 23 passes through between the V-shaped plates 22; The filter layer 23 passes through the filter bin 21 and extends to the bottom of the filter bin 21, and the filter layer 23 is connected end to end; a sealing strip is provided in the filter bin 21 on one side where the filter layer 23 passes through the filter bin 21; The filter layer 23 is rotatably connected via four rotating shafts, one of which is driven by a first motor 24, and the first motor 24 is mounted on the filter box 2; A circulation pump 25 is installed on the end surface of one side of the filter box 2 close to the soil source heat pump unit 1, and the water inlet end of the circulation pump 25 extends into the filter bin 21; uniformly arranged nozzles 26 are installed at the bottom of the filter bin 21, and the nozzles 26 are connected to the external air pump through an air pipe; An inlet pipe 14 is installed on the water outlet end of the circulation pump 25; an outlet pipe 12 is installed on the water inlet pipe 11; underground pipes 15 are evenly arranged below the inlet pipe 14 and the outlet pipe 12, and the underground pipes 15 are used to be buried in the soil layer; the water inlet end of the underground pipe 15 is connected to the inlet pipe 14, and the water outlet end of the underground pipe 15 is connected to the outlet pipe 12; The underground pipe 15 is provided with a cleaning component, and the cleaning component is used to clean the dirt in the underground pipe 15; The underground pipe 15 is provided with a transfer component, and the transfer component is used to prevent dirt from clogging the underground pipe 15 when the cleaning component is cleaning dirt; Specifically, when the soil source heat pump unit 1 is in use, the first motor 24 is first controlled to start, and the first motor 24 will drive the filter layer 23 to slowly circulate through the rotating shaft. The circulating filter layer 23 will circulate through the filter chamber 21. Since two pairs of V-shaped plates 22 are provided in the filter chamber 21, the filter layer 23 passing through the filter chamber 21 will move in a V-shaped motion trajectory. Since a sealing strip is provided in the filter chamber 21 on one side where the filter layer 23 passes through the filter chamber 21, the filter layer 23 passing through the filter chamber 21 can be sealed. The position is sealed to prevent the water in the filter chamber 21 from flowing out. When the water in the soil source heat pump unit 1 is discharged through the water outlet pipe 13, the discharged water will fall on the V-shaped filter layer 23, and then the water will pass through the filter layer 23, and the impurities in the water will be filtered on the filter layer 23. Since the filter layer 23 circulates and rotates in the filter chamber 21, the rotating filter chamber 21 will drive the filtered impurities to move. When the filter layer 23 is rotated out of the filter chamber 21, the impurities on the filter chamber 21 are also taken out by the filter layer 23; More specifically, when the filter layer 23 drives the impurities to rotate to the bottom of the filter bin 21, multiple nozzles 26 will blow air to the back of the filter layer 23, and the flowing gas will pass through the filter layer 23. When the gas contacts the impurities on the filter layer 23, the impurities filtered on the filter layer 23 can be blown off, and then the impurities will fall into the filter box 2. Since the filter layer 23 is cyclically rotated, the filter layer 23 can filter the water cyclically, and then the filtered impurities are blown off by the nozzles 26. In this process, the content of impurities in the water can be reduced, thereby avoiding excessive impurity content in the water. When water flows in the buried pipe 15 for a long time, dirt will be generated in the buried pipe 15, which will not only reduce the heat exchange effect of the buried pipe 15, but also reduce the flow rate of the buried pipe 15. At the same time, it can avoid excessive impurities on the filter layer 23, thereby reducing the water permeability of the filter layer 23. Furthermore, after the water passes through the filter layer 23, the circulation pump 25 will pump the water into the inlet pipe 14. The water entering the inlet pipe 14 will enter the buried pipe 15 from the water inlet end of the buried pipe 15. Then the water will flow downward in the buried pipe 15. Heat will be exchanged during the flow of the water. When the water flows to the outlet end, the water will enter the outlet pipe 12. Then the water entering the outlet pipe 12 will enter the ground source heat pump unit 1 again. Then the ground source heat pump unit 1 will provide heating or cooling to the building, and the cycle will continue. Furthermore, since a cleaning component is provided in the buried pipe 15, when the buried pipe 15 needs to be cleaned, the buried pipe 15 can be cleaned by the cleaning component. At the same time, since a transfer component is provided on the buried pipe 15, if there is too much dirt in the buried pipe 15, the transfer component can be used to discharge the dirt in advance, thereby avoiding the accumulation of dirt in the buried pipe 15 and the occurrence of blockage.

[0019] Embodiment 2: The water inlet and outlet ends of the buried pipe 15 are both fixedly installed with arc-shaped pipes 3, and a distance is left between the two arc-shaped pipes 3; The ends of the two arc-shaped pipes 3 are both threadedly mounted with end caps 31; the cleaning assembly includes a pull rope 32, which is a steel wire rope; the pull rope 32 passes through the buried pipe 15, and the pull rope 32 is in a loose state in the buried pipe 15; The two ends of the pull rope 32 are respectively tied to the two end covers 31; single knots 33 are tied at equal distances on the pull rope 32; The cleaning assembly further includes a ball 34; a circular groove 35 is formed in the middle of the ball 34; a through groove 36 is formed on the circular groove 35, and the through groove 36 passes through half of the ball 34; The surface of the ball 34 is fixedly connected to the annular layer 37, and an opening is provided on one side of the annular layer 37 close to the through groove 36. When cleaning the buried pipe 15, the pull rope 32 is passed through the opening of the annular layer 37, and then the rope is passed from the through groove 36 into the circular groove 35, and then the rope is pulled, and the single knot 33 on the rope will push the ball 34 to move in the buried pipe 15. In this embodiment, the annular layer 37 is made of rubber material; In this embodiment, a driving rod 38 is provided between the two arc-shaped tubes 3; One side of the driving rod 38 rotates on the filter box 2, and the other side rotates on the soil source heat pump unit 1, and is driven by the second motor 39; when cleaning the inside of the buried pipe 15, the pull rope 32 is passed over the driving rod 38 and connected end to end, and then the rotating driving rod 38 can drive the pull rope 32 to rotate; Specifically, when the buried pipe 15 needs to be cleaned, the end cover 31 is first removed, and the rope tied to the end cover 31 is removed from the end cover 31, and then the rope is connected head to tail, and the rope is passed through the opening of the annular layer 37, and then the rope is passed through the through groove 36 into the circular groove 35, and then the rope is rotated in a circular manner, and the single knot 33 on the rope pushes the ball 34 to move into the buried pipe 15. When multiple balls 34 enter the buried pipe 15, the introduction pipe 14 is then Remove it from the circulating water pump, connect the inlet pipe 14 to the external liquid pump, and remove the outlet pipe 12 from the water inlet pipe 11. Then use the external liquid pump to pass water into the inlet pipe 14. When the water enters the buried pipe 15, the water flow will push the ball 34 to circulate in the buried pipe 15. The circulated ball 34 will drive the annular layer 37 to scrape the inner wall of the buried pipe 15, so that the dirt in the buried pipe 15 can be scraped off and move with the annular layer 37. More specifically, when the dirt pushed by the ball 34 and the annular layer 37 moves into the transfer assembly, the transfer assembly can first discharge the dirt, thereby preventing excessive dirt from moving with the ball 34 and the annular layer 37 and causing the dirt to be blocked in the buried pipe 15. Since the annular layer 37 is made of rubber material, the buried pipe 15 will not be damaged during the circular rotation of the annular layer 37 following the pull rope 32. When water flows out of the buried pipe 15, the dirt can be driven to flow directly from the water outlet end of the buried pipe 15 to the outside. Furthermore, in the process of the pull rope 32 driving the ball 34 and the annular layer 37 to rotate cyclically, the second motor 39 can be controlled to rotate, and the second motor 39 will drive the driving rod 38 to rotate, and the rotating driving rod 38 will drive the pull rope 32 to rotate. In this process, it can be prevented that the water entering the buried pipe 15 cannot drive the ball 34 and the annular layer 37 to rotate cyclically, and the pull rope 32 can be manually rotated to rotate cyclically; By setting the ball 34 and the annular layer 37 to circulate and rotate in the buried pipe 15, the dirt in the buried pipe 15 can be discharged, thereby avoiding excessive dirt in the buried pipe 15, which will affect the heat exchange effect of the buried pipe 15. At the same time, since the annular layer 37 is made of rubber material, the buried pipe 15 will not be damaged during the process of the annular layer 37 following the pull rope 32. Due to the existence of the transfer component, the transfer component can first discharge part of the dirt, thereby avoiding excessive dirt following the ball 34 and the annular layer 37 to move and cause the dirt to be blocked in the buried pipe 15.

[0020] Embodiment 3: The buried pipe 15 comprises two top pipes 151 and a bottom pipe 152; The transfer assembly includes a transfer chamber 4; a transfer chamber 4 is provided between the two top pipes 151 and the bottom pipe 152; a transfer chamber 4 is also provided between the two bottom pipes 152, and multiple transfer chambers 4 can be provided on the buried pipe 15; The top tube 151 or the bottom tube 152 extends into the corresponding transfer bin 4 and is connected to the transfer bin 4; the pull rope 32 passes through the transfer bin 4; In this embodiment, the space in the transfer bin 4 at the bottom is arc-shaped; a conduit 41 is installed on the top of the transfer bin 4 at the bottom, and the conduit 41 extends above the ground; a round tube 42 is rotatably connected in the conduit 41, and the top of the round tube 42 extends above the conduit 41; a sewage suction pump can be installed on the top of the round tube 42; The bottom of the round tube 42 extends into the transfer bin 4 at the bottom and is staggered with the pull rope 32; arc plates 43 are provided on both sides of the round tube 42 located in the transfer bin 4, and the arc plates 43 are fixedly connected in the transfer bin 4 and fit with the surface of the round tube 42; A notch 44 is formed on one side of the circular tube 42 close to the arc plate 43, and the notch 44 is initially sealed by the arc plate 43; The transfer bin 4 in the middle is fixedly connected with a connecting pipe 45, and the connecting pipe 45 is connected with the conduit 41; the circular tube 42 is provided with a round opening 46 on one side close to the conduit 41, and the round opening 46 is staggered with the connecting pipe 45 in the initial state; In this embodiment, the top pipe 151 and the bottom pipe 152 in the transfer bin 4 on both sides are staggered; the top of the inner circle of the bottom pipe 152 is rounded; In this embodiment, the transfer bin 4 is made of stainless steel; Specifically, when cleaning the buried pipe 15, first rotate the circular pipe 42 by 90 degrees. After the circular pipe 42 rotates, the notch 44 at the bottom of the circular pipe 42 is located between the two arc-shaped plates 43 and is connected to the transfer bin 4 at the bottom. At the same time, the circular opening 46 in the middle of the circular pipe 42 coincides with the connecting pipe 45. Then, the sewage pump is connected to the circular pipe 42 and the sewage pump is started. When the external liquid pump pumps water into the buried pipe 15 and the ball 34 drives the annular layer 37 to move, the top pipe 151 and the bottom pipe 152 in the transfer bin 4 are staggered. When the annular layer 37 is moved, the top pipe 151 and the bottom pipe 152 in the transfer bin 4 are staggered. After the dirt pushed by the annular layer 37 moves to the transfer bins 4 on both sides, the dirt will fall into the transfer bins 4, and the water pumped into the buried pipe 15 will also flow into the transfer bins 4. Since the transfer bin 4 is connected to the circular pipe 42 through the connecting pipe 45, during the operation of the sewage pump, the dirt and part of the water in the transfer bin 4 can be pumped into the circular pipe 42 through the connecting pipe 45, and then pumped out of the circular pipe 42 and discharged from the sewage pump. In this process, it can be avoided that the dirt pushed by the annular layer 37 accumulates on each other, thereby blocking the buried pipe 15. More specifically, the ball 34 and the annular layer 37 will then enter the bottom tube 152. Since the inner ring top of the bottom tube 152 is rounded, the ball 34 and the annular layer 37 will enter the bottom tube 152 more easily. When the ball 34 and the annular layer 37 move from the bottom tube 152 to the transfer bin 4 at the bottom, dirt and water will enter the arc space of the bottom transfer bin 4. Since the pull rope 32 and the circular tube 42 are staggered, the dirt pushed by the annular layer 37 will move to the side of the circular tube 42 and align with the notch 44 opened on the circular tube 42. At this time, the circular tube 42 can extract the dirt and water in the bottom transfer bin 4, and the number of transfer bins 4 can be set according to the length of the buried pipe 15. Since the transfer bin 4 is made of stainless steel, it is ensured that the transfer bin 4 is in the soil layer and will not be corroded or damaged. Furthermore, after the local buried pipe 15 is cleaned, the sewage suction pump is removed from the circular pipe 42, and the circular pipe 42 is rotated back to the initial state, and then the external liquid pump is removed from the outlet pipe 12, and the inlet pipe 14 is installed back on the circulation pump 25, and the outlet pipe 12 is installed back on the water inlet pipe 11.
