Description

Technical Field

[0001] This utility model relates to the field of wastewater recycling technology, and in particular to an air source heat pump condensate recycling device. Background Technology

[0002] When an air source heat pump is running, the refrigerant in the evaporator evaporates and absorbs heat, causing the surface temperature of the evaporator to drop below the air dew point temperature.

[0024] 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. Example

[0025] This embodiment discloses an air source heat pump condensate recovery device, which is used to quickly clean and collect condensate on the surface of the air source heat pump evaporator, and to process and reuse the condensate.

[0026] Most existing recovery devices are collection devices placed below the evaporator to wait for the condensate to drip naturally. Only a small amount of condensate can be collected from the bottom, and a lot of condensate remains in the corners and gaps of the evaporator fins. At low temperatures, the condensate is prone to freezing and clogging the fin gaps, affecting the heat exchange efficiency of the heat pump and causing damage to components.

[0027] like Figure 1 and Figure 2 As shown, an air source heat pump condensate recovery device includes a housing 1, a collection box 2 fixedly connected to the lower side inside the housing 1, a water collection trough that gradually slopes downward from left to right between the upper side of the collection box 2 and the evaporator, for collecting condensate dripping from the evaporator fins and accumulating it to the right, a storage chamber inside the collection box 2 for storing the treated condensate, a symmetrically distributed cleaning mechanism 3 for cleaning the evaporator on the upper side inside the housing 1, a symmetrically distributed recovery mechanism 4 for collecting condensate on the lower side inside the housing 1, an axisymmetrically distributed power mechanism 5 for providing power to the cleaning structure and the collection mechanism inside the housing 1, and a filter mechanism 6 for treating the condensate on the collection box 2. like Figure 2-4 As shown, the cleaning mechanism 3 includes: a support rod 301, which is slidably connected to the outer shell 1. A support frame 302 is fixedly connected to the support rod 301. Several evenly distributed gas nozzles 303 are installed on the support frame 302. The high-pressure gas sprayed from the gas nozzles 303 blows off the condensate and impurities in the gaps and surface of the evaporator fins, thereby preventing condensate from remaining in the gaps of the evaporator fins and increasing the condensate cleaning efficiency. like Figure 2 and Figures 5-7As shown, the recycling mechanism 4 includes: an extension rod 401, which is slidably connected to the outer casing 1. A fixed rod 402 is fixedly connected to the extension rod 401. The fixed rod 402 is provided with an upper guide groove and a lower guide groove, which are used to guide the scraped condensate water to prevent it from dripping into the device. The upper side of the scraper 403 is provided with a low-temperature resistant flexible scraper strip, which is used to adapt to the low-temperature environment of the evaporator surface, increase its service life, and maintain a tight fit with the evaporator surface. The lower side of the scraper 403 is provided with evenly distributed drainage grooves, which are used to prevent the condensate water scraped by the scraper 403 from dripping directly, making it easier to collect the condensate water. In addition to the treatment, the fixed rod 402 is provided with a drain hole for discharging the condensate collected by the scraper 403. The scraper 403 is fixed to the fixed rod 402. A water-absorbing cotton 404 is provided on the lower side of the drainage groove of the scraper 403. The water-absorbing cotton 404 is used to absorb the condensate in the drainage groove to prevent the condensate from falling too fast under the action of gravity and detaching from the drainage groove of the scraper 403. The water-absorbing cotton 404 is located between the drainage groove of the scraper 403 and the lower guide groove of the fixed rod 402. The scraper strip on the scraper 403 quickly scrapes off and collects the condensate on the surface of the evaporator, which is convenient for subsequent treatment of the condensate and prevents the condensate from dripping into the device.

[0028] like Figures 3-5 As shown, the power mechanism 5 includes: symmetrically distributed electric conveyor belts 501, which are arranged on the left and right sides inside the housing 1. Each symmetrically distributed electric conveyor belt 501 has a transmission block 502 fixedly connected to it. Each transmission block 502 is rotatably connected to a slider 503. A centrally symmetrically distributed sliding seat 504 is slidably connected inside the housing 1. The sliding seat 504 is slidably connected to the adjacent transmission block 502. The upper sliding seat 504 is rotatably connected to symmetrically distributed support rods 301. An elastic element, which is a torsion spring, is provided between each symmetrically distributed support rod 301 and the adjacent sliding seat 504. The lower sliding seat 504 is fixedly connected to symmetrically distributed extension rods 401. The upper sliding seat 504 is rotatably connected to the symmetrically distributed extension rods 401. An electric reel 505 is installed inside the seat 504. The electric reel 505 and the symmetrically distributed support rods 301 are connected by steel wire ropes. When the electric reel 505 rotates to reel in the wire, the support rods 301 on the front and rear sides rotate simultaneously, causing several gas nozzles 303 that are distributed in a mirror image to swing in the same direction at the same time. This allows the gas nozzles 303 at different angles to produce different cleaning effects on the evaporator. The electric conveyor belt 501 drives the upper cleaning mechanism 3 to move up and down reciprocally, performing high-pressure gas impact cleaning on the evaporator. The electric conveyor belt 501 drives the lower recovery mechanism 4 to move up and down reciprocally, scraping off and collecting the condensate on the surface of the evaporator, thus comprehensively cleaning and recovering the condensate on the surface of the evaporator.

[0029] like Figure 8 and Figure 9As shown, the filtration mechanism 6 includes: a filter frame 601, which is fixed to the right side of the collection box 2. A connecting hole is provided on the upper side of the filter frame 601. This connecting hole is a frustum-shaped structure with a diameter gradually decreasing from top to bottom, used to concentrate and downwardly flow condensate and accelerate the water flow speed under water pressure. The drain hole of the fixing rod 402 is connected to the connecting hole of the filter frame 601 through a telescopic pipe. The water collection tank of the collection box 2 is connected to the connecting hole of the filter frame 601. A first filter cylinder 602 is fixedly connected to the filter frame 601. A double-layer filter screen 6021 is slidably connected inside the first filter cylinder 602. The upper filter screen of filter 6021 has a higher filtration accuracy than the lower filter screen. This allows the upper screen to filter large particles and the lower screen to filter small particles. This division of filtration reduces the frequency of filter cleaning and replacement, ensuring water quality for the secondary use of condensate. A distance detector 6022 is slidably connected inside the first filter cylinder 602. An elastic element, a spring, is provided between the distance detector 6022 and the first filter cylinder 602. The distance detector 6022 is slidably connected to the double-layer filter screen 6021 and is used for detection... The displacement of the double-layer filter screen 6021 is measured. The more impurities remain on the double-layer filter screen 6021, the greater the impact force of the water flow on the double-layer filter screen 6021, and the longer the downward displacement distance of the double-layer filter screen 6021. This is used to determine the amount of impurities on the double-layer filter screen 6021 and quickly determine whether the double-layer filter screen 6021 needs to be replaced or cleaned. A second filter screen 603 is fixed to the lower side of the first filter screen 602. The second filter screen 603 contains several activated carbons. The activated carbons are used to remove trace pollutants and odors that cannot be intercepted by the filter screen, further improving the water quality of the condensate. Collection box. The system is equipped with symmetrically distributed water pumps 604. The inlet of the water pump 604 on the right side is connected to the connecting hole of the second filter cylinder 603, the first filter cylinder 602, and the filter frame 601. The outlet of the water pump 604 on the right side is connected to the storage chamber of the collection tank 2. The inlet of the water pump 604 on the left side is connected to the storage chamber of the collection tank 2. Impurities in the condensate are filtered by the double-layer filter screen 6021, and other pollutants and odors are removed by activated carbon, thereby ensuring the water quality of the condensate for subsequent secondary water resource utilization and reducing environmental pollution.

[0030] When the air source heat pump starts running, condensation begins to form on the evaporator surface. At this time, the user controls the electric reel 505 inside the upper sliding seat 504 to rotate. When the electric reel 505 rotates counterclockwise (as shown in the image), it causes condensation to form on the evaporator surface. Figure 4(As shown in the direction), the electric reel 505 simultaneously retracts the steel wire ropes on the front and rear support rods 301, causing the front support rod 301 to rotate clockwise, and its torsion spring to twist and store energy. The rear support rod 301 rotates counterclockwise, and its torsion spring to twist and store energy. The front and rear support rods 301 drive the adjacent support frame 302 to swing upwards simultaneously, causing several evenly distributed gas nozzles 303 on them to swing upwards. The closer the angle between the gas nozzle 303 and the side of the evaporator is to perpendicular, the smaller the angle between the gas nozzle 303 and the side of the evaporator, the stronger the cleaning ability on the outside of the evaporator. The larger the angle between the gas nozzle 303 and the side of the evaporator, the stronger the cleaning ability on the inside of the evaporator fins. The angle of the gas nozzle 303 is adjusted in the above way until the required cleaning intensity is achieved.

[0031] After the angle of the gas nozzle 303 is adjusted, the operator controls the gas nozzles 303, which are evenly and symmetrically distributed on the upper side, to simultaneously begin spraying high-pressure gas. Then, the operator controls the electric conveyor belts 501 on both sides to start simultaneously. The left electric conveyor belt 501 drives the transmission block 502 on it to move downwards. The transmission block 502 drives the adjacent slider 503 to move downwards. The slider 503 drives the adjacent sliding seat 504 to move downwards. The sliding seat 504 drives the two support rods 301 at the front and rear to move downwards simultaneously. The support rods 301 drive the adjacent support frame 302 to move downwards. The gas nozzles 303, which are evenly distributed on the evaporator, move downwards simultaneously. The high-pressure gas ejected from the gas nozzles 303 impacts the surface of the evaporator and the gaps between its fins. Driven by the electric conveyor belt 501, the gas nozzles 303 cover the entire evaporator with high-pressure gas. The condensate on the surface of the evaporator fins is guided downwards and discharged into the water collection tank on the upper side of the collection box 2. If a high rate of condensate generation is detected on the surface of the evaporator, the user can control the gas nozzles 303 to spray gas at a higher pressure, thereby increasing the cleaning efficiency of the condensate.

[0032] As the gas nozzle 303 moves downward, the electric conveyor belt 501 on the right side drives the transmission block 502 on it to move upward. The transmission block 502 drives the adjacent slider 503 to move upward. The slider 503 drives the adjacent sliding seat 504 to move upward. The sliding seat 504 drives the two extension rods 401 at the front and rear to move upward simultaneously. The extension rod 401 drives the adjacent fixed rod 402 to move upward. The fixed rod 402 drives the adjacent scraper 403 to move upward. The scraper strip on the scraper 403 remains in close contact with the evaporator fins. As the scraper 403 moves upward, the scraper strip scrapes off the condensate on the surface of the evaporator fins. Under the action of gravity, the condensate flows through the scraper 403 and enters the upper guide groove of the fixed rod 402. Under the action of the upper guide groove of the fixed rod 402, it flows to the right and is discharged through the drain hole on the right side of the fixed rod 402, preventing the condensate on the surface of the evaporator from flowing aimlessly and causing it to diffuse into the equipment.

[0033] After the electric conveyor belt 501 on the right moves the mirror-distributed scraper blades 403 upward to their limit position, the electric conveyor belt 501 moves the mirror-distributed scraper blades 403 downward. The scraper strips on the scraper blades 403 remain in close contact with the evaporator fins, allowing the remaining condensate on the surface of the evaporator fins to continue to be scraped downward. After being scraped by the scraper strips on the scraper blades 403, the condensate is kept in a flowing state on the scraper blades 403 by the evenly distributed drainage grooves on the lower side of the scraper blades 403, preventing the condensate from dripping and spreading outside the recycling point when it is scraped downward. The condensate flows into the absorbent cotton 404 under the guidance of the drainage grooves. The absorbent cotton 404 absorbs the condensate and slowly releases it into the lower guide groove of the fixed rod 402. The condensate also flows to the right under the action of the lower guide groove and is discharged through the drain hole on the right side of the fixed rod 402.

[0034] After the condensate is discharged through the expansion pipe from the drain hole on the right side of the fixed rod 402, the condensate flows into the connecting hole on the upper side of the filter frame 601. The condensate collected in the water collection tank 2 flows to the right into the connecting hole of the filter frame 601 under the action of gradually tilting downward from left to right. The condensate in the connecting hole of the filter frame 601 flows downward into the first filter cylinder 602. When the condensate flows through the first filter cylinder 602, the condensate first contacts the filter screen on the upper side of the double-layer filter screen 6021 and is filtered. Then the condensate contacts the filter screen on the lower side of the double-layer filter screen 6021 and is filtered again. Under the filtration of the upper filter screen, large particles of impurities are filtered, and under the filtration of the lower filter screen, small particles of impurities are filtered. Through the division of filtration, the frequency of cleaning and replacement of the filter screen is reduced, and water quality is guaranteed for the secondary use of condensate.

[0035] During the filtration process of the double-layer filter screen 6021, impurities in the condensate remain on the filter screen. The condensate continues to impact the filter screen, causing the double-layer filter screen 6021 to move downwards under the impact force. The double-layer filter screen 6021 drives the distance detector 6022 to move downwards, and the spring of the distance detector 6022 is compressed and stored until the impact force on the filter screen is equal to the spring force, until the double-layer filter screen 6021 moves downwards to the limit position of the distance detector 6022. The distance detector 6022 then uploads the data to notify the user, indicating that there are too many impurities remaining on the double-layer filter screen 6021. The user then pulls the double-layer filter screen 6021 upwards, cleans off the impurities, and puts it back on top of the distance detector 6022. The distance detector 6022 moves upwards to return to its initial position under the action of the spring. By replacing the filter screen in a timely manner, the filtration efficiency of the condensate is ensured.

[0036] After the condensate is filtered by the first filter cartridge 602, it flows into the second filter cartridge 603. The activated carbon in the second filter cartridge 603 adsorbs the condensate, removing trace pollutants and odors that the filter screen cannot intercept, further improving the water quality. The condensate continues to flow downwards to the water pump 604 on the right. The user starts the water pump 604, which transports the filtered condensate to the storage chamber of the collection tank 2 to store and accumulate the filtered condensate. When the air source heat pump is short of water, the user can start the water pump 604 on the left to transport the water stored in the storage chamber of the collection tank 2 to the water-scarce location. Alternatively, the left water pump 604 can be used to discharge excess condensate, thereby achieving secondary utilization of water resources, reducing equipment operating costs, and reducing environmental pollution.

[0037] After the air source heat pump stops operating, condensate production ceases on the evaporator surface. The electric conveyor belt 501 drives several evenly distributed gas nozzles 303 and scrapers 403 to continue moving up and down repeatedly until the condensate on the evaporator surface is cleaned and recovered. Then, the electric conveyor belt 501 drives the evenly distributed gas nozzles 303 and scrapers 403 back to their initial positions. The operator controls the electric conveyor belts 501 on both sides to stop, and simultaneously controls all gas nozzles 303 to stop spraying high-pressure gas. Finally, the water pumps 604 on both sides are stopped, and the remaining filtered condensate is stored in the storage chamber of the collection box 2. This completes the recycling and treatment of the air source heat pump condensate.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
