Description

Technical Field

[0001] This invention belongs to the field of heat pump heating technology, and specifically relates to a heat pump heating device. Background Technology

[0002] A heat pump heating system is an energy-saving device that uses high-grade energy (such as electricity or heat) to transfer heat energy from low-grade heat sources (such as air, water, soil, and industrial waste heat) to high-grade heat sources (such as indoor air and domestic hot water) to achieve heating or hot water supply. Its core principle is to use a reverse Carnot cycle to transfer heat from a low-temperature environment to a high-temperature environment with a small amount of high-grade energy input, thereby improving energy efficiency. Heat pump heating systems are commonly used in household or space heating systems. Common heat pumps are classified into air-source heat pumps, water-source heat pumps, and ground-source heat pumps.

[0003] Ground source heat pump heating is a technology that utilizes 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). Its core principle is based on the heat pump cycle, which uses a small amount of high-grade energy input to drive the refrigerant to circulate in components such as the evaporator, compressor, condenser, and expansion valve, thereby transferring low-grade heat energy to high-grade heat energy.

[0004] Specifically, when a water source heat pump is working, water is first introduced into the evaporator inside the heat pump. The water exchanges heat with the refrigerant in the evaporator, transferring the low-grade heat energy it carries to the refrigerant, causing it to evaporate into a low-temperature, low-pressure gas. Subsequently, the low-temperature, low-pressure gas is compressed by the compressor into a high-temperature, high-pressure gas, a process that consumes a small amount of electrical energy. After entering the condenser, the high-temperature, high-pressure gas releases heat to the building's circulating water (for heating or domestic hot water) or air (for cooling), causing the circulating water to heat up or the air to cool down. Finally, the refrigerant returns to the evaporator after being depressurized and cooled by the expansion valve, starting a new cycle. Through this cycle, the water source heat pump heating device can efficiently provide heating, cooling, and domestic hot water services for residential or commercial spaces.

[0005] When a water source heat pump is working, it needs to clean impurities from the water source through a filter plate. However, after a period of use, suspended matter will accumulate on the surface of the filter plate, and impurities will be trapped in the mesh. It needs to be cleaned in time. However, the use of the filter plate needs to be suspended during cleaning, which will prevent the water source from being filtered in time. This will result in a reduction in the amount of clean water entering the heat pump unit per unit time and a decrease in the overall water source treatment efficiency. In some large commercial places or industrial production, there will be significant fluctuations in indoor temperature.

[0006] Therefore, the present invention provides a heat pump heating device. Summary of the Invention

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] like Figures 1 to 11 As shown, the present invention provides a technical solution: a heat pump heating device, including a processing box 1, an inlet pipe 2 fixedly connected to the top of the processing box 1, a heat pump body 4 provided on one side of the processing box 1, a delivery pipe 3 fixedly connected between the processing box 1 and the heat pump body 4, a compressor, an evaporator, a condenser and a throttling valve provided inside the heat pump body 4, two downward rotatable filter screens 5 provided inside the processing box 1, a flow diversion assembly provided above the two filter screens 5, the flow diversion assembly including a rotatable guide plate 9, the guide plate 9 can adjust the flow path of the water source in the processing box 1 by rotation, a guide chamber 16 fixedly connected to both sides of the processing box 1, a scraping assembly provided above the two filter screens 5, the scraping assembly including a scraper 11, the scraper 11 can move in both directions, thereby physically cleaning the surface of the filter screens 5 in the standby state, and a mesh cleaning assembly provided below the two filter screens 5 to clean the mesh of the downward rotatable filter screens 5.

[0037] During operation: In common heat pump heating devices, water source heat pumps deliver water (such as groundwater, rivers, lakes, etc.) into the device, where it exchanges heat with the evaporator in the heat pump. This replenishes the heat required for refrigerant evaporation or removes the heat released by refrigerant condensation, thereby transferring low-grade heat energy to high-grade heat energy. This device mainly solves some problems encountered during the use of water source heat pumps. In the initial state of use, the diversion plate 9 is located above the left filter plate 5. At this time, the diversion plate 9 blocks the top of the left filter plate 5, so that the water source flows into the treatment chamber 1 through the liquid inlet pipe 2. At this time, under the diversion effect of the diversion plate 9, the water entering the treatment tank 1 will flow to the filter plate 5 set on the right. At this time, the filter plate 5 on the right side plays the role of interception and filtration, intercepting larger suspended solids and smaller impurity particles in the water. After the filter plate 5 on the right side has been used for a period of time, suspended solids will accumulate on its upper surface, and some intercepted impurity particles will be stuck in the mesh. If the suspended solids and impurity particles are not cleaned in time, the interception and filtration effect of the filter plate 5 will gradually decrease, thereby affecting the flow rate of the water. In order to solve this problem, the diversion component can be used to make the diversion plate 9 perform... As the water flow plate 9 rotates, it adjusts its position and angle. Water entering the treatment chamber 1 is then directed by the water flow plate 9 to the filter screen 5 on the left side, where it intercepts and filters the water. Meanwhile, the filter screen 5 on the right side is in standby mode. First, a scraping component cleans the surface of the right filter screen 5 of suspended matter. After cleaning, a mesh cleaning component below the right filter screen 5 performs a deep cleaning of the mesh, restoring its permeability. After the filter plate 5 is cleaned twice, the filter plate 5 on the right side restores its original interception and filtration effect, while the filter plate 5 on the left side has been working for a period of time and the filter plate 5 on the right side has been cleaned. By adjusting the angle of the guide plate 9, the two filter plates 5 can be used alternately to perform filtration again. The two filter plates 5 use this alternating method to continuously treat the water source. The treated water source will flow to the bottom of the treatment box 1 through the filter plates 5 and can flow into the heat pump body 4 through the delivery pipe 3. Heat exchange will take place inside the heat pump body 4 to complete the entire heating process.

[0038] The processing box 1 is made of high-strength, corrosion-resistant special stainless steel. This material can withstand the temperature changes that may occur during the operation of the heat pump and the corrosion of chemical substances that may exist in the water source. The heat pump body 4 is made of engineering plastic with excellent heat insulation performance. The internal key components such as the compressor, evaporator, and condenser are all made of high-efficiency, energy-saving, high-temperature and high-pressure resistant high-quality materials.

[0039] The heat pump unit 4 internally houses a compressor, evaporator, and condenser. The compressor, as the core power component, is a high-efficiency, energy-saving compressor with powerful compression capabilities, quickly compressing low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure gas to power the entire heat pump cycle. The evaporator employs a high-efficiency heat exchange tube bundle structure, with copper tubes providing excellent thermal conductivity and rapidly absorbing heat from the water source to evaporate the refrigerant. The evaporator surface undergoes special treatment to increase the heat exchange area and improve heat exchange efficiency. The condenser also uses copper tubes, and its structure... The design is reasonable, enabling the high-temperature, high-pressure refrigerant gas to dissipate heat fully in the condenser, transferring heat to the heating system and achieving heat transfer. The condenser is equipped with heat dissipation fins made of aluminum alloy, which are lightweight and have good heat dissipation performance, quickly dissipating the heat in the condenser to the surrounding environment. In addition, the heat pump body 4 is equipped with a throttling device, which uses a high-precision throttling valve to accurately control the flow and pressure of the refrigerant, ensuring the stable operation of the heat pump system. The heat pump body and its internal key components are existing technologies and will not be described in detail here.

[0040] Through the above embodiments, the flow path of the water source in the treatment tank 1 is dynamically adjusted by the diversion component and the rotatable diversion plate 9, realizing the alternating use of the two filter plates 5. In the initial state, the diversion plate 9 blocks the left filter plate 5, causing all the water source to flow to the right filter plate 5. When the right filter plate needs cleaning, the diversion plate 9 is rotated to change its position and angle, guiding the water source to the left filter plate 5, and the right filter plate enters the standby state. Through alternating switching, it is ensured that the water source is always effectively filtered, maintaining the stability of the heating system and preventing a single filter plate 5 from becoming clogged or losing efficiency due to long-term use. The scraping component physically cleans the surface of the filter plate 5 in the standby state, peeling off the intercepted suspended matter from the surface of the plate, removing large suspended particles, preventing them from clogging the mesh or covering the filter medium, and improving filtration efficiency. The mesh cleaning component deeply cleans the mesh of the filter plate 5, removing small impurities stuck inside the mesh, restoring the permeability of the mesh, and avoiding increased water flow resistance or decreased flow rate due to clogging.

[0041] like Figures 3 to 4 As shown, the diversion assembly also includes an isolation bearing seat 6, which is fixedly installed inside the processing chamber 1 and located directly above the two filter screens 5. The isolation bearing seat 6 divides the upper part of the two filter screens 5 into a first filter chamber 7 and a second filter chamber 8. The outer wall of the shaft of the isolation bearing seat 6 is fixedly connected to the inner wall of one end of the diversion plate 9. The top of the processing chamber 1 is set in an arc shape. A servo motor 10 is fixedly installed on the outer wall of the processing chamber 1. The output shaft of the servo motor 10 is fixedly connected to the shaft of the isolation bearing seat 6. The output shaft of the servo motor 10 passes through and is rotatably connected to the side wall of the processing chamber 1.

[0042] During operation: The isolation bearing seat 6 divides the top space of the treatment chamber 1 into filter chamber 1 7 and filter chamber 2 8. In the initial state, when the servo motor 10 is not started, the guide plate 9 naturally deflects towards filter chamber 1 7. At this time, the surface of the guide plate 9 just blocks the inlet of filter chamber 1 7, preventing the water entering the treatment chamber 1 from the inlet pipe 2 from flowing to the area above the left filter screen 5. At the same time, the inclined surface of the guide plate 9 forms a guide slope, guiding the water along its surface to the space above the right filter screen 5, ensuring that all the water is filtered by the right filter screen 5. When the right filter screen 5 becomes clogged or its filtration efficiency decreases due to the accumulation of impurities from long-term filtration, the servo motor 10 starts and drives the shaft of the isolation bearing seat 6 to rotate. The servo motor 10 drives the diversion plate 9 to swing towards the second filter chamber 8 until it blocks the inlet of the second filter chamber 8. At this time, the water source is forcibly guided above the left filter screen plate 5, and the left filter screen plate 5, which was originally idle, takes over the filtration task from the right filter screen plate 5. After the right filter screen plate 5 has finished cleaning, the servo motor 10 drives the diversion plate 9 to swing back to the initial position, restoring the filtration work of the right filter screen plate 5. At the same time, the left filter screen plate 5 enters the idle state to perform cleaning work. Through the forward and reverse rotation control of the servo motor 10, the diversion plate 9 can swing back and forth between the inlets of the two filter chambers, dynamically switching the filtration path of the water source, realizing the alternating use of the two filter screen plates 5, and ensuring that the heating system always maintains efficient and stable filtration performance.

[0043] like Figure 2 and Figure 6 As shown, the scraper 11 is located directly above the center of the two filter screens 5, and the bottom of the scraper 11 can fit against the upper surface of the two filter screens 5. Both outer walls of the processing box 1 are fixedly installed with drive electric slides 12, and the inner walls of the drive electric slides 12 are slidably connected with electric sliders 13. The electric sliders 13 are fixedly connected to both sides of the scraper 11 through round rods, and the round rods are slidably connected to the side wall of the processing box 1.

[0044] During operation: In the initial state, the scraper 11 is located above the center of the two filter screens 5. After the left filter screen 5, which was originally idle, takes over the filtration task from the right filter screen 5, the drive electric slide block 12 is activated to control the electric slider 13 to move to the right along its inner wall. The electric slider 13 drives the scraper 11 to move to the right synchronously through the round rod. At this time, the bottom of the scraper 11 is in close contact with the upper surface of the right filter screen 5. During the movement, the friction between the plate surface and the screen is used to remove impurities, particles and flocculent matter attached to the surface of the right filter screen 5. As the scraper 11 continues to move to the right, the scraped impurities are pushed to the slag collection area on the right edge of the filter screen 5. When it is necessary to clean the left filter screen 5, the electric slider 13 is controlled to move to the left, and the scraper 11 moves to the left simultaneously and performs the same scraping action on the left filter screen 5. The direction of movement of the scraper 11 above the two filter screens 5 is controlled by the direction of movement of the electric slider 13, which can clean the suspended matter intercepted on the surface of the two filter screens 5 respectively, ensuring the continuous cleanliness and high-efficiency filtration performance of the two filter screens 5.

[0045] like Figures 4 to 5 As shown, the drainage chamber 16 is located on one side of each of the two filter screens 5. A collection box 17 is provided below each drainage chamber 16. An opening and closing component is provided at the connection position between the processing box 1 and the two drainage chambers 16. The opening and closing component can flexibly control the connection and closure of the channel between the processing box 1 and the drainage chamber 16.

[0046] During operation: Initially, both opening and closing components are closed, sealing the connection between the treatment chamber 1 and the diversion chamber 16. This ensures that all water flowing through the filter screen 5 for normal filtration remains inside the treatment chamber 1 and does not leak into the diversion chamber 16. When the scraper 11 moves to the right to clean the suspended matter attached to the surface of the right filter screen 5, the right filter screen 5 is in an idle state with no water flowing in because the diversion component has already made it idle. When the scraper 11 reaches the edge of the right filter screen 5, the right opening and closing components automatically open, and the originally closed channel... When activated, the scraper 11 continuously pushes the suspended matter. Under the combined action of gravity and the thrust of the scraper 11, the suspended matter smoothly enters the right-side drainage chamber 16 and falls accurately into the corresponding collection box 17 along the preset flow path inside the drainage chamber 16 for centralized collection. After the right-side filter screen 5 is cleaned, when the scraper 11 returns to its initial position, the right-side opening and closing component automatically closes to restore its initial state. Similarly, when the scraper 11 moves to the left to clean the left-side filter screen 5, the left-side opening and closing component will also automatically open and close according to the same principle to achieve the collection of suspended matter on the left side.

[0047] like Figures 3 to 5As shown, each of the opening and closing components includes a hinge seat 15. The hinge seat 15 is fixedly installed at the connection between the processing box 1 and the drainage chamber 16. A blocking plate 14 is fixedly connected to the outer wall of the shaft of the hinge seat 15. A torsion spring 18 is fixedly connected to one side of the blocking plate 14. The end of the torsion spring 18 away from the blocking plate 14 is fixedly connected to the side of the hinge seat 15.

[0048] During operation: In the initial state, the blocking plate 14 is vertical, tightly sealing the connection between the treatment chamber 1 and the diversion chamber 16, ensuring that the water being filtered does not flow into the diversion chamber 16; when the scraper 11 cleans the suspended matter on the right filter screen 5, as the scraper 11 pushes the suspended matter to the right blocking plate 14, under the action of the scraper 11, the blocking plate 14 will hinge and rotate around the shaft of the hinge seat 15 as the fulcrum, changing to a horizontal state, while compressing the torsion spring 18 to deform it. Subsequently, the scraper 11 can push the suspended matter to move along the surface of the blocking plate 14; after the scraper 11 passes the blocking plate 14, the suspended matter will fall into the interior of the diversion chamber 16 and finally fall into the collection box 17. Similarly, when the scraper 11 cleans the left filter screen 5, the blockage plate 14 of the left opening and closing assembly will also operate according to the same principle to collect the suspended matter on the left. After the scraper 11 completes the collection and reset of the suspended matter, the torsion spring 18 can cause the blockage plate 14 to rotate in the opposite direction and reset to the vertical blocking state.

[0049] like Figures 7 to 8 As shown, the mesh cleaning assembly includes a partition plate 19, which is located below the two filter screens 5 and is fixedly connected to the inner wall of the processing chamber 1. Several cleaning rods 33 are fixedly connected to both sides of the partition plate 19. The cleaning rods 33 are identical to the filter screens 5 in number, arrangement, and shape. A dual-axis clamping member 20 is fixedly connected to the top of the partition plate 19. The two shafts of the dual-axis clamping member 20 are fixedly connected to the inner wall of one end of the two filter screens 5 respectively. A drive assembly is provided on the outside of the processing chamber 1 to drive the two filter screens 5 to rotate downwards.

[0050] During operation: After the right-side filter screen plate 5 completes the cleaning of suspended solids, the corresponding drive component is activated, causing the right-side filter screen plate 5 to rotate downwards with one of the shafts of the dual-axis clamping member 20 as the fulcrum. During the downward rotation of the right-side filter screen plate 5, its mesh holes gradually approach the cleaning rods 33 on the partition plate 19. As the rotation angle increases, each mesh hole will be precisely inserted into the corresponding cleaning rod 33. During the insertion of the cleaning rod 33 into the mesh hole, it will push and remove the impurities and flocculent matter remaining in the mesh hole, thereby achieving a deep cleaning of the mesh holes of the right-side filter screen plate 5, ensuring the permeability of the mesh holes and improving the subsequent filtration effect. Similarly, after the left-side filter screen plate 5 completes the corresponding working stage, the corresponding drive component can also be activated to make it rotate downwards and use the cleaning rods 33 to complete the mesh hole cleaning.

[0051] like Figures 9 to 10 As shown, the drive assembly includes two arc-shaped slides 23, which are fixedly installed on the outer wall of the processing box 1. Arc-shaped sliders 22 are slidably connected to the inner wall of each arc-shaped slide 23. A slide rod 21 is fixedly connected to one side of each arc-shaped slider 22. The slide rod 21 is slidably connected to the outer wall of the processing box 1. The outer wall of the slide rod 21 is fixedly connected to the inner wall of the filter plate 5 away from the dual-axis clamping member 20. A multi-stage arc-shaped telescopic rod 24 is fixedly connected to the inner wall of each arc-shaped slide 23. One end of the multi-stage arc-shaped telescopic rod 24 is fixedly connected to the bottom surface of the arc-shaped slider 22.

[0052] During operation: When the drive component is started, the multi-stage arc-shaped telescopic rod 24 begins to retract, and its retraction force acts on the arc-shaped slider 22, pushing the arc-shaped slider 22 to slide along a specific arc-shaped trajectory on the inner wall of the arc-shaped slide block 23. While the arc-shaped slider 22 is sliding, it drives the slide rod 21 to slide on the outer wall of the processing box 1. The slide rod 21 will further drive the filter screen plate 5, which is fixedly connected to it, to rotate downward with the shaft of the double-axis clamp 20 as the fulcrum, so as to realize the downward rotation of the filter screen plate 5, so that the mesh of the filter screen plate 5 can be cleaned by the cleaning rod 33 later.

[0053] like Figures 7 to 8 As shown, two feed plates 25 are provided below the partition plate 19. The feed plates 25 and the partition plate 19 divide the lower part of the filter screen plate 5 into a first feed chamber 26 and a second feed chamber 27. The conveying pipe 3 is connected to one side of the first feed chamber 26 and the second feed chamber 27 respectively. A rotating shaft 28 is fixedly connected to the inner wall of one end of each feed plate 25. The rotating shaft 28 is rotatably connected to the side wall of the processing box 1. A gear assembly that drives the rotating shaft 28 to rotate is provided on the outside of the filter screen plate 5.

[0054] During operation: In the initial state, the two feed plates 25 are in a combined state. After the water source filtered by the filter screen plate 5 enters the feed chamber 1 26 or the feed chamber 27, it will be transported to the heat pump body 4 through the delivery pipe 3 for reaction. When the right filter screen plate 5 rotates downward to clean the mesh, all the water source in the feed chamber 27 has been transported to the heat pump body 4. During the downward rotation of the right filter screen plate 5, the gear assembly drives the right feed plate 25 to rotate downward with the rotating shaft 28 as the fulcrum. At this time, the filter screen plate 5 is in an inclined state. Under the action of the cleaning rod 33, the impurities cleaned from the mesh fall along the inclined surface of the filter screen plate 5 to the top of the feed plate 25. Since the feed plate 25 is also inclined downward, the impurities can fall along the inclined surface of the feed plate 25 to the bottom of the processing box 1, realizing the collection of impurities cleaned from the mesh and preventing them from being remixed with the water source entering the feed chamber 27 later.

[0055] like Figures 9 to 11 As shown, the gear assembly includes two gears 32, which are fixedly connected to the outer walls of two rotating shafts 28 respectively. Both shafts of the dual-shaft clamping member 20 are fixedly connected to extension rods 29. The outer walls of the extension rods 29 are fixedly connected to connecting outer rods 30. One end of the connecting outer rods 30 is fixedly connected to an arc-shaped rack plate 31. The teeth of the arc-shaped rack plate 31 mesh with the teeth of the gears 32 respectively.

[0056] During operation: When the right-side filter screen plate 5 rotates downwards, it drives the corresponding shaft of the dual-axis clamping component 20 to rotate. This shaft, through the extension rod 29 and the connecting outer rod 30, drives the arc-shaped rack plate 31 to rotate synchronously. Since the arc-shaped rack plate 31 meshes with the right-side gear 32, the rotation of the arc-shaped rack plate 31 drives the right-side gear 32 to rotate. The right-side gear 32 is fixed on the right-side rotating shaft 28, which in turn drives the right-side rotating shaft 28 to rotate. The rotation of the right-side rotating shaft 28 causes the right-side feed plate 25 to rotate downwards around the rotating shaft 28. Similarly, when the left-side filter screen plate 5 rotates, it also drives the left-side feed plate 25 to rotate downwards through the corresponding transmission structure on the left, achieving a linkage effect between the rotation of the feed plate 25 and the filter screen plate 5. This allows for the timely collection of impurities cleaned from the mesh of the filter screen plate 5, preventing them from re-mixing with subsequent water sources.

[0057] like Figure 7 and Figure 11 As shown, a material collection box 34 is provided at the bottom of the processing box 1, and the material collection box 34 is slidably connected to the inner wall of the processing box 1.

[0058] During operation: Impurities falling through the inclined feed plate 25 will fall into the collection box 34, and the impurities can be collected and processed by removing the collection box 34.
