Description

Technical Field

[0001] The present invention relates to the technical field of water source heat pump heating devices, and more specifically, to a heating device of a water source heat pump unit. Background Art

[0002] A heat pump is a highly efficient energy-saving device that makes full use of low-grade thermal energy. Heat can be transferred spontaneously from a high-temperature object to a low-temperature object, but not spontaneously in the opposite direction. The working principle of a heat pump is a mechanical device that forces heat from a low-temperature object to a high-temperature object in a reverse cycle. It consumes only a small amount of reverse cycle net work to obtain a large amount of heating capacity, and can effectively utilize low-grade thermal energy that is difficult to use to achieve energy-saving purposes. A water source heat pump is a low-grade thermal energy resource formed by utilizing solar energy and geothermal energy absorbed in shallow water sources on the earth's surface, such as groundwater, rivers and lakes. It uses the heat pump principle and a small amount of high-level electrical energy input to achieve the transfer of low-level thermal energy to high-level thermal energy.

[0003] The patent with publication number CN114322368A discloses a combined heating device for a water source heat pump unit, including a pump body for absorbing groundwater and a water supply pipe fixed to the water inlet of the pump body, a filter screen for filtering groundwater is arranged in the water supply pipe, a positioning block for hindering the filter screen from moving in the water supply pipe is fixedly connected to the inner wall of the water supply pipe, and a clamping mechanism for hindering the filter screen from moving away from the positioning block is arranged on the side of the filter screen away from the positioning block. The device has the effect of reducing the possibility of the pipeline aperture in the water source heat pump unit becoming smaller or even causing blockage, thereby improving the working efficiency of the water source heat pump unit.

[0004] During use, the above-mentioned device is equipped with a filter inside the pipe to filter impurities in the water. However, when surface water is heated inside the heating device, scale will form, and the scale will adhere to the internal pipe of the heating device and cause blockage. In order to solve the scale problem, water is generally heated outside and then transported to the inside of the heating device, thereby reducing the problem of scale adhering to the inside of the pipe of the heating device. Although the scale is reduced, the scale will still enter the heating device through the pipe, causing blockage and damage to the heating device. If a filter is added inside the pipe, the scale can be filtered, but the filter is in a static state. When water flows through, the scale will still adhere to the filter, causing blockage.

[0034] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0035] like Figures 1 to 5As shown, a heating device of a water source heat pump unit described in an embodiment of the present invention comprises a bottom plate 1, on which two support plates 11 are fixedly mounted, an evaporator 12 and a condenser 13 are fixedly mounted inside the two support plates 11, a water outlet 131 and a water inlet 132 are arranged at the end of the condenser 13, a soft water delivery pipe 15 is fixedly mounted on the side of the water inlet 132, an electric boiler 14 is fixedly mounted at the end of the soft water delivery pipe 15, a filter plate 23 is slidably mounted inside the soft water delivery pipe 15, an anti-adhesion filter device 2 is arranged inside the soft water delivery pipe 15, and the anti-adhesion filter device 2 is used to drive the filter plate 23 to vibrate to prevent scale adhesion; the anti-adhesion filter device 2 is used to drive the filter plate 23 to vibrate to prevent scale adhesion; The filtering device 2 includes a power scraping component 24. When water flows into the soft water delivery pipe 15, the power scraping component 24 is driven to rotate and vibrate, which is used to drive the filter plate 23 to vibrate. A vibration component 25 is arranged at the center of the power scraping component 24. The vibration component 25 slides inside the filter plate 23 to adjust the angle of the power scraping component 24 and scrape the scale filtered on the surface of the filter plate 23; an anti-blocking device 3 is arranged inside the soft water delivery pipe 15. The movement of the filter plate 23 drives the vibration component 25 to engage and transmit with the anti-blocking device 3. The anti-blocking device 3 can drive the vibration component 25 to transmit and at the same time, it can make holes in the holes inside the filter plate 23.

[0036] It should be noted that since pipes are provided inside the condenser 13, if groundwater or sewage is directly transported to the inside of the condenser 13, the water will be heated inside the condenser 13, and the sewage or groundwater will form scale inside the condenser 13, thereby adhering to the inside of the condenser 13 and causing damage to the condenser 13. In addition, the condenser 13 and the parts inside it are of high value, and it is difficult to repair them if damaged. In order to reduce scale, hard water is generally converted into soft water before sewage or groundwater enters the condenser 13. However, during the heating and transportation process of soft water, a large amount of scale will still enter the inside of the condenser 13 through the pipes. In order to solve this problem, the following improvements have been made.

[0037] First, the water heated inside the electric boiler 14 is transported to the position of the water inlet 132 through the soft water delivery pipe 15, and then enters the interior of the condenser 13 through the water inlet 132. In this process, the power scraper component 24 is affected by the fluidity of the water flow inside the soft water delivery pipe 15, so that the power scraper component 24 rotates. The rotation of the power scraper component 24 makes the water flow near the filter plate 23 more fluid, and the soft water delivery pipe 15 is provided with a filter plate 23 inside, which can isolate the scale in the water, thereby preventing the scale from entering the interior of the condenser 13 and causing blockage and precipitation problems. Since the scale is more likely to adhere to a stationary object when being transported in the water flow, it is easy to adhere to the inside of the pipe, and the center of the power scraper component 24 is provided with a vibration component 25. When the power scraper component 24 rotates, it can drive the vibration component 25 to rotate, thereby The component 24 and the filter plate 23 have a vibrating effect to prevent the filter plate 23 from being in a stationary state during filtering, resulting in the problem of scale adhesion. When the filter plate 23 filters a lot of scale, the permeability of the filter plate 23 becomes poor. Therefore, when water flows through the inside of the filter plate 23, it drives the filter plate 23 to move toward the water inlet 132. During the movement, the vibration component 25 contacts and engages with the anti-blocking device 3. The anti-blocking device 3 rotates and drives the vibration component 25 to slide on the central inner wall of the filter plate 23, thereby changing the angle of the power scraping component 24. Driven by the anti-blocking device 3, the surface of the filter plate 23 can be scraped to prevent scale adhesion. During the rotation of the anti-blocking device 3, the mesh of the filter plate 23 is cleaned to prevent the filter plate 23 from being blocked and the pipes inside the condenser 13 from having scale adhesion.

[0038] like Figures 5 to 7 As shown, a first slide groove 151 is provided inside the soft water delivery pipe 15, and the anti-adhesion filtering device 2 also includes a first fixed rod 21 fixedly installed inside the first slide groove 151, and a first fixed block 221 is slidably installed on the outer wall of the first fixed rod 21, and a first spring 22 is fixedly installed on the side wall of the first fixed block 221, and a filter plate 23 is fixedly installed on the side wall of the first fixed block 221, and the center inner part of the filter plate 23 is slidably installed with the vibration component 25, and the outer wall of the vibration component 25 is fixedly installed with the power scraping component 24, and the side wall of the filter plate 23 is fixedly installed with a limiting component 26, and the limiting component 26 is engaged with the anti-blocking device 3 to drive the power scraping component 24 to adjust the angle.

[0039] It should be noted that, when the filter plate 23 is in a normal filtering state, the first fixing rod 21 is in a fully popped-out maximum state, and the first fixing block 221 is at the farthest end away from the anti-blocking device 3. When the filter plate 23 is in a blocked state, the water flow can push the filter plate 23 to move in a direction close to the anti-blocking device 3, and the filter plate 23 drives the first fixing block 221 and the power scraping component 24, the vibration component 25 and the limit component 26 to move in a direction close to the anti-blocking device 3. During the movement, the anti-blocking device 3 rotates and engages with the vibration component 25, thereby pulling the vibration component 25, so that the vibration component 25 slides inside the filter plate 23, and the sliding of the vibration component 25 drives the rotation angle of the power scraping component 24 to change, thereby scraping the surface of the filter plate 23 to prevent the problem of scale clogging. The limit component 26 engages with the bevel gear on the anti-blocking device 3 to limit the bevel gear, so that the anti-blocking device 3 cleans the holes on the filter plate 23 to prevent the problem of scale sticking to the inside of the holes.

[0040] like Figure 7 As shown, a second groove 231 is provided at the center of the filter plate 23, and the vibration assembly 25 includes a first rotating column 251 movably installed inside the center of the filter plate 23, and a telescopic adjustment block 254 is slidably installed on the inner wall of the second groove 231, and the telescopic adjustment block 254 is rotatably installed with the first rotating column 251. The two side walls of the telescopic adjustment block 254 are respectively fixedly installed with a third spring 253 and a fourth spring 255, and the end of the third spring 253 is fixedly installed with the side wall of the second groove 231, and the side wall of the fourth spring 255 is fixedly installed with the power scraping assembly 24. A cam block 252 is fixedly installed at the end of the first rotating column 251, and the rotation of the first rotating column 251 is used to drive the cam block 252 to shake, and a long gear 256 is fixedly installed on the side wall of the telescopic adjustment block 254, and the long gear 256 is used to drive the power scraping assembly 24 to adjust the angle.

[0041] It should be noted that the first rotating column 251 is movably installed inside the filter plate 23, and the first rotating column 251 is provided with an internal thread 2511, which can be combined with the threaded rod on the anti-blocking device 3, thereby driving the first rotating column 251 to rotate. When the filter plate 23 is in a normal state, the first rotating column 251 and the filter plate 23 are in a state of rotational connection, and the power scraping component 24 rotates under the action of the water flow, thereby driving the first rotating column 251 and the cam block 252 to rotate. The rotation of the cam block 252 can vibrate the vibration component 25 and the filter plate 23 to prevent the filter plate 23 from being in a static state during use, and the surface of the filter plate 23 is easily adhered to scale. The telescopic adjustment block 254 slides inside the second groove 231, and the telescopic adjustment block The side wall of 254 is provided with a fourth spring 255 and a third spring 253, so that under normal circumstances, the side wall of the first rotating column 251 close to the anti-blocking device 3 is in the same plane with the side wall of the filter plate 23, and the side wall of the telescopic adjustment block 254 away from the anti-blocking device 3 is in the same plane with the other side wall of the filter plate 23. When the internal thread 2511 inside the first rotating column 251 is engaged with the threaded rod on the anti-blocking device 3, the first rotating column 251 can be driven to move in the direction close to the anti-blocking device 3, thereby driving the power scraping component 24 at the end of the vibration component 25 to move in the direction close to the anti-blocking device 3, so that the long gear 256 slides inside the power scraping component 24, and the angle of the power scraping component 24 changes, thereby scraping and transporting the surface of the filter plate 23.

[0042] like Figures 7 to 9 As shown, the power scraping assembly 24 includes a square rotating block 249 fixedly mounted on the outer wall of the first rotating column 251, and a square adjusting block 247 is fixedly mounted on the side wall of the square rotating block 249. A first gear 246 is rotatably mounted inside the square adjusting block 247, and a fan blade scraper block 241 is fixedly mounted on the end of the first gear 246. The long gear 256 is meshed with the first gear 246, and the movement of the long gear 256 is used to drive the first gear 246 and the fan blade scraper block 241 to rotate and adjust the angle.

[0043] It should be noted that when the distance between the square rotating block 249 and the telescopic adjustment block 254 changes, the long gear 256 and the square rotating block 249 slide, which drives the first gear 246 to rotate, and the end of the first gear 246 is fixedly connected to the fan blade scraper block 241, thereby driving the fan blade scraper block 241 to rotate 45° so that the side of the fan blade scraper block 241 is perpendicular to the side of the filter plate 23, so that during the rotation process, the scale filtered on the surface of the filter plate 23 is scraped off, and the scraped scale is precipitated and falls through the opening set at the bottom end of the soft water delivery pipe 15, thereby preventing the scale from adhering to the filter plate 23 and preventing the scale from clogging the surface of the filter plate 23.

[0044] like Figures 7 to 9 As shown, the power scraping assembly 24 also includes an elastic metal sheet 243 slidably installed inside the edge of the fan blade scraper block 241, and a fourth transmission rod 242 is fixedly installed on the side of the elastic metal sheet 243, and a second limit block 245 is fixedly installed on the outer wall of the fourth transmission rod 242, and a second spring 244 is fixedly installed on the side wall of the second limit block 245, and the second limit block 245 slides inside the fan blade scraper block 241, and the side wall of the square adjustment block 247 is provided with a third slide groove 248, and the end of the fourth transmission rod 242 passes through the interior of the fan blade scraper block 241 and contacts the inner wall of the third slide groove 248.

[0045] It should be noted that, since the maximum distance between the two blade scrapers 241 is smaller than the inner diameter of the soft water delivery pipe 15, when the blade scraper 241 rotates to scrape the side wall of the filter plate 23, the force of the scale water flow may not be able to smoothly fall into the opening set inside the soft water delivery pipe 15. Therefore, an elastic metal sheet 243 is slidably installed inside the blade scraper 241. When the blade scraper 241 rotates to be perpendicular to the side of the filter plate 23, the fourth transmission rod 242 inside the blade scraper 241 can be driven to rotate, and the end of the fourth transmission rod 242 slides inside the third slide groove 248, so that the blade scraper 241 can rotate during the rotation. During the process, the fourth transmission rod 242 is driven to push out the elastic metal sheet 243, and the elastic metal sheet 243 is an elastic structure, which can bend when it fits with the inner wall of the soft water delivery pipe 15, and the surface of the fan blade scraper 241 is a curved surface, and the rotation direction of the fan blade scraper 241 is the same as the direction of the curved surface. Therefore, when the fan blade scraper 241 rotates to scrape off the scale, the curved surface of the fan blade scraper 241 can transport the scale, thereby transporting the scale on the side of the filter plate 23 to the inner wall of the soft water delivery pipe 15, and rotating with the elastic metal sheet 243, so that it falls when passing through the opening inside the soft water delivery pipe 15, thereby having the effect of cleaning and transporting the scale.

[0046] like Figure 5 to Figure 6 and Figure 10 to Figure 11As shown, the anti-blocking device 3 includes a third transmission rod 36 fixedly installed inside the soft water delivery pipe 15, a transmission block 35 is fixedly installed at the end of the third transmission rod 36, a second transmission rod 34 is rotatably installed inside the transmission block 35, an L-shaped limit block 32 is rotatably installed on the outer wall of the second transmission rod 34, a first transmission rod 31 is rotatably installed inside the L-shaped limit block 32, a plurality of bristles 311 are fixedly installed on the outer wall of the first transmission rod 31, a first bevel gear 312 is fixedly installed at the end of the first transmission rod 31, a third bevel gear 341 is fixedly installed at the end of the second transmission rod 34, and the third bevel gear 341 is A threaded column 342 is fixedly installed on the end, and a second bevel gear 33 is rotatably installed on the outer wall of the threaded column 342. A limiting hole 331 is arranged inside the second bevel gear 33, and the limiting hole 331 is used to engage with the limiting assembly 26. The third bevel gear 341, the first bevel gear 312 and the second bevel gear 33 are engaged for transmission. A motor fixing box 37 is fixedly installed on the outer wall of the soft water delivery pipe 15 at the lower end of the third transmission rod 36. A rod is arranged inside the third transmission rod 36 and is connected to the motor fixing box 37 for transmission. The rod inside the third transmission rod 36 is connected to the second transmission rod 34 for transmission through a gear.

[0047] It should be noted that when the filter plate 23 is blocked, the filter plate 23 is driven to move in the direction close to the anti-blocking device 3 under the action of water pressure. When the threaded column 342 contacts the first rotating column 251, the starting motor drives the rod inside the third transmission rod 36 to rotate, thereby mobilizing the second transmission rod 34 and the threaded column 342 to rotate. The rotation of the threaded column 342 causes the first rotating column 251 to move in the direction of the threaded column 342. When the threaded column 342 is tightened with the first rotating column 251, the rotation of the threaded column 342 can drive the first rotating column 251 to rotate, thereby driving the fan blade scraper 241 to scrape the surface of the filter plate 23, and the second bevel gear 33 is rotated to be installed on the outer wall of the threaded column 342. The inner part of the second bevel gear 33 is A limiting hole 331 is provided, and the limiting hole 331 can mesh with the limiting component 26, so that the second bevel gear 33 can be limited during the rotation process, and the rotation of the second transmission rod 34 drives the third bevel gear 341 to rotate, and the rotation of the third bevel gear 341 drives the first bevel gear 312 to rotate, and the second bevel gear 33 is limited under the action of the limiting component 26, so that when the first bevel gear 312 rotates, it drives the first transmission rod 31 and the bristles 311 to rotate synchronously, and at the same time, the first transmission rod 31, the bristles 311 and the first bevel gear 312 rotate with the second transmission rod 34 as the center of the circle, so that the holes on the filter plate 23 can be cleaned during the rotation process to prevent the problem of scale combining and adhering to the holes inside the filter plate 23.

[0048] like Figures 8 to 11As shown, the limiting assembly 26 includes a third fixed column 261 fixedly mounted on the side wall of the filter plate 23, a fourth limiting cylinder 263 is slidably mounted on the outer wall of the third fixed column 261, a fifth spring 262 is fixedly mounted on the side wall of the fourth limiting cylinder 263, the fifth spring 262 is concentric with the third fixed column 261, the diameter of the fourth limiting cylinder 263 is the same as the diameter of the limiting hole 331, and the limiting assembly 26 is used to limit the second bevel gear 33.

[0049] It should be noted that the surface of the fourth limiting cylinder 263 is rounded, and the position of the fourth limiting cylinder 263 is not necessarily in the same state as the center of the limiting hole 331. Therefore, when the filter plate 23 approaches the second bevel gear 33, the fifth spring 262 can play a buffering role during the movement.

[0050] like Fig.11 As shown, an internal thread 2511 is provided at the center of the side wall of the first rotating column 251 , and the internal thread 2511 is used to connect with the threaded column 342 , and the diameter of the threaded column 342 is the same as the diameter of the internal thread 2511 .

[0051] It should be noted that the threaded column 342 can engage with the internal thread 2511 during the rapid rotation process, and during the engaged rotation process, the first rotating column 251 can be driven to move toward the threaded column 342 .

[0052] like Figure 5 As shown, a flap 27 is rotatably installed on the inner wall of the soft water delivery pipe 15, a torsion spring is provided at the position where the flap 27 is connected to the inner wall of the soft water delivery pipe 15, and a collection box 28 is fixedly installed on the outer wall of the soft water delivery pipe 15 at the lower end of the flap 27.

[0053] It should be noted that when the fan blade scraper 241 is perpendicular to the side wall of the filter plate 23, the filter plate 23 has moved toward the direction close to the threaded column 342, and the filter plate 23 moves to Figure 5 On the left side of the flap 27 shown in the figure (close to the direction of the transmission block 35), when the elastic metal sheet 243 extends out and slides on the inner wall of the soft water delivery pipe 15 and passes the position of the flap 27, a rotating shaft is provided at the center position of the flap 27. Therefore, when the elastic metal sheet 243 passes by, the flap 27 can be driven to rotate, so that the scale falls into the interior of the collection box 28, thereby achieving the cleaning effect.

[0054] like Figure 5 and Figure 8As shown, the diameter of the fan blade scraper 241 is smaller than the inner diameter of the soft water delivery pipe 15. When the elastic metal sheet 243 is extended to the maximum, the maximum distance between the fan blade scraper 241 and the two ends of the elastic metal sheet 243 is greater than the inner diameter of the soft water delivery pipe 15.

[0055] It should be noted that the diameter of the fan blade scraper 241 is smaller than the inner diameter of the soft water delivery pipe 15. When the elastic metal sheet 243 is extended to the maximum, the maximum distance between the fan blade scraper 241 and the two ends of the elastic metal sheet 243 is greater than the inner diameter of the soft water delivery pipe 15, so that the flap 27 can be pushed open during the rotation of the elastic metal sheet 243, thereby removing the scale.

[0056] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
