Description

Technical Field

[0001] This utility model belongs to the field of filtration device technology, specifically referring to a filtration device for an air source heat pump. Background Technology

[0002] In air source heat pump systems, the cleanliness of water, the heat exchange medium, directly affects the operating efficiency and lifespan of the equipment.

[0003] Existing filtration devices often suffer from the following problems: First, the sedimentation units are mostly flat-bottomed, making it easy for impurities to accumulate at the bottom and adhere to the walls. Cleaning requires draining the water or manual scraping, which can leave residues, damage equipment, and incur high labor costs. Furthermore, the lack of a stirring mechanism results in slow sedimentation, requiring multiple tanks to be used alternately, increasing the footprint and investment. Second, the filter modules are fixed by snap-fit ​​or bolts, which can lead to gaps due to installation errors and long-term deformation and loosening. This results in 15%-30% of unfiltered water flowing through the system, causing impurities to cause scale buildup in the heat pump, increasing power consumption and component failures. Users need to frequently replace modules or add filters, increasing costs and the size of the device. Utility Model Content

[0004] To address the aforementioned challenges, this invention provides a filtration device for an air source heat pump unit. By integrating efficient sedimentation, multi-stage precise filtration, convenient maintenance, and equipment protection functions, it achieves high efficiency and automation throughout the entire water treatment process, significantly improving the operational stability and economy of the air source heat pump system.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: A filtration device for an air source heat pump includes a base plate. An inclined-bottom sedimentation tank, a filter box, a water storage tank, and an air source heat pump are installed on the base plate. A stirring mechanism is installed inside the inclined-bottom sedimentation tank. An inclined-bottom groove is formed at the bottom of the inclined surface of the sedimentation tank. A collection trough is detachably installed inside the inclined-bottom groove. A blocking horizontal bar slides through the bottom of the inclined surface of the sedimentation tank. The blocking horizontal bar is adapted to seal the opening of the collection trough. The blocking horizontal bar is pulled out from one side of the inclined-bottom sedimentation tank, allowing the sediment in the sedimentation tank to naturally slide into the collection trough for cleaning. A first water pump and a second water pump are also installed on the base plate. The input end of the first water pump is connected to the pipe of the inclined-bottom sedimentation tank, and the delivery end of the first water pump is connected to the pipe of the filter box. The input end of the second water pump is connected to the pipe of the filter box, and the delivery end of the second water pump is connected to the pipe of the water storage tank.

[0006] As a preferred embodiment of this utility model, the filter box is a box structure with an open top. The top opening of the filter box is detachably fitted with a box cover. A baffle filter module is installed under the box cover. A pressing mechanism is provided on the opposite side walls of the filter box.

[0007] As a preferred embodiment of this utility model, the pressing mechanism includes a support block, an electric telescopic rod, and a pressing block. The support block is fixedly installed on the outer wall of the filter box, the electric telescopic rod is fixedly installed on the support block, and the pressing block is rotatably mounted on the output end of the electric telescopic rod.

[0008] As a preferred technical solution of this utility model, the stirring mechanism includes a drive motor, a rotating shaft, and stirring rods. The drive motor is installed on the outer wall of the inclined bottom sedimentation tank, and the output end of the drive motor passes through the side wall of the inclined bottom sedimentation tank. The rotating shaft is connected to the output end of the drive motor. Multiple stirring rods are arranged in a ring array. The stirring mechanism makes the impurities in the water evenly dispersed and accelerates the sedimentation, avoids the local accumulation of impurities, improves the sedimentation efficiency, and allows more large particles of impurities to be separated in advance.

[0009] As a preferred embodiment of this utility model, the baffle filter module includes a baffle plate and a V-shaped filter screen, wherein the V-shaped filter screen is fixed to the side of the baffle plate facing the water flow.

[0010] As a preferred embodiment of this utility model, one side of the water storage tank is connected to an air source heat pump.

[0011] Compared with the prior art, the present invention achieves the following beneficial effects by adopting the above structure: 1. The inclined bottom sedimentation tank, combined with the stirring mechanism, uses a ring array of stirring rods to evenly disperse impurities and accelerate sedimentation. The inclined design promotes the natural accumulation of impurities at the bottom. The combination of the detachable collection tank and the sliding sealing bar allows for quick cleaning of sedimented impurities without draining the water, reducing manual operation and downtime. 2. The baffle filter module installed under the cover of the filter box fully filters the water flow. The pressing mechanism on both sides is driven by an electric telescopic rod to rotate the pressure block. The downward pressure makes the baffle filter module fit tightly against the inner wall of the filter box, avoiding gaps and ensuring filtration accuracy. 3. The filter box features an opening at the top and a removable cover, facilitating quick replacement of the baffle filter module. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0016] like Figures 1-5As shown, the present invention provides a filtration device for an air source heat pump, comprising a base plate 1, on which a sloping-bottom sedimentation tank 2, a filter box 3, a water storage tank 4, and an air source heat pump 5 are mounted. A stirring mechanism 6 is installed inside the sloping-bottom sedimentation tank 2. A sloping-bottom groove 201 is formed at the bottom of the sloping surface of the sedimentation tank 2, and a collection trough 202 is detachably fitted inside the sloping-bottom groove 201. A sealing crossbar 203 slides through the bottom of the sloping surface of the sedimentation tank 2, and the sealing crossbar 203 is fitted to seal the opening of the collection trough 202. When the sealing crossbar 203 is pulled out from one side of the sloping-bottom sedimentation tank 2, the sediment in the sloping-bottom sedimentation tank 2 is allowed to settle naturally. The water then slides into the collection tank 202 for cleaning. Water pump 7 and water pump 8 are also installed on the base plate 1. The input end of water pump 7 is connected to the pipe of the inclined bottom sedimentation tank 2, and the delivery end of water pump 7 is connected to the pipe of the filter box 3. The input end of water pump 8 is connected to the pipe of the filter box 3, and the delivery end of water pump 8 is connected to the pipe of the water storage tank 4. One side of the water storage tank 4 is connected to the air source heat pump 5. The filtered clean water is stored in the water storage tank 4 and then supplied to the air source heat pump 5 for heat exchange. The clean water reduces internal scaling and component blockage in the air source heat pump 5, extends the service life of the equipment, and ensures the efficient operation of the air source heat pump 5.

[0017] like Figure 1 and Figure 4 As shown, the filter box 3 is a box structure with an open top. The top opening of the filter box 3 is detachably fitted with a box cover 301. A baffle filter module is installed under the box cover 301. A clamping mechanism 9 is provided on the opposite side walls of the filter box 3. The baffle filter module filters the water entering the filter box 3. The clamping mechanisms 9 on both sides can fix the position of the module. The box cover 301 of the filter box 3 facilitates the installation and replacement of the baffle filter module. The clamping mechanism 9 ensures the stable operation of the module and improves the reliability of filtration.

[0018] like Figures 4-5 As shown, the pressing mechanism 9 includes a support block 901, an electric telescopic rod 902, and a pressing block 903. The support block 901 is fixedly installed on the outer wall of the filter box 3, the electric telescopic rod 902 is fixedly installed on the support block 901, and the pressing block 903 is rotatably mounted on the output end of the electric telescopic rod 902. The extension and retraction of the electric telescopic rod 902 drives the pressing block 903 to move. After the pressing block 903 rotates to adjust the angle, it tightly presses the baffle filter module to ensure that the module fits seamlessly with the inner wall of the filter box 3. The electric control realizes automatic pressing. The rotation of the pressing block 903 adapts to the shape of the module to prevent water from flowing through the gaps and affecting the filtration effect.

[0019] like Figure 1 , Figure 2 and Figure 4As shown, the stirring mechanism 6 includes a drive motor 601, a rotating shaft 602, and stirring rods 603. The drive motor 601 is installed on the outer wall of the inclined bottom sedimentation tank 2, and the output end of the drive motor 601 passes through the side wall of the inclined bottom sedimentation tank 2. The rotating shaft 602 is connected to the output end of the drive motor 601. Multiple sets of stirring rods 603 are arranged in a ring array. The drive motor 601 drives the rotating shaft 602 to rotate. The multiple sets of ring array stirring rods 603 agitate the water in the inclined bottom sedimentation tank 2, so that the impurities in the water are evenly dispersed and the sedimentation is accelerated, avoiding local accumulation of impurities, improving sedimentation efficiency, and allowing more large particles of impurities to be separated in advance.

[0020] The baffle filter module includes a baffle plate and a V-shaped filter screen. The V-shaped filter screen is fixed on the side of the baffle plate facing the water flow. The filter screens are respectively a fine-pore stainless steel mesh, a quartz sand composite mesh, and an activated carbon fiber mesh. When the water flows into the V-shaped filter screen, it passes through the fine-pore stainless steel mesh to intercept large particles, the quartz sand composite mesh to filter fine impurities, and the activated carbon fiber mesh to adsorb pollutants in sequence. The baffle plate extends the water flow path to enhance the filtration effect, the multi-layer filter screen improves water quality through graded filtration, the V-shaped structure increases the filtration area, and the baffle design extends the contact time for more thorough filtration.

[0021] In practical use, the water to be treated is introduced into the inclined bottom sedimentation tank 2, and flocculant is added into the inclined bottom sedimentation tank 2. The drive motor 601 is started, and the drive motor 601 drives the rotating shaft 602 to rotate. The stirring rods 603 of multiple ring arrays stir the water in the inclined bottom sedimentation tank 2, so that the impurities in the water are evenly dispersed and the sedimentation is accelerated. The impurities gather towards the bottom of the inclined surface under the action of gravity. The first water pump 7 is started to pump the clear water in the upper layer of the inclined bottom sedimentation tank 2 into the filter box 3. The water flows through the V-shaped filter screen and the baffle plate extends the water flow path to enhance the filtration effect. The second water pump 8 is started to pump the clean water in the filter box 3 into the water storage tank 4. The clean water in the water storage tank 4 is delivered to the air source heat pump 5 as needed for heat exchange. When the sediment accumulates to a certain amount, stop the water intake, pull out the blocking bar 203 from one side of the inclined bottom sedimentation tank 2, and the impurities at the bottom of the inclined surface will naturally slide into the collection tank 202 in the inclined bottom trough 201 under the action of gravity. After cleaning, take out the collection tank 202 and empty the impurities, reset the collection tank 202 and insert the blocking bar 203 back in, turn off water pump 7 and water pump 8 at regular intervals, open the cover 301 of the filter box 3, control the electric telescopic rod 902 to extend so that the pressure block 903 is loosened, take out the baffle filter module for cleaning or replacement, reset the module after replacement, control the electric telescopic rod 902 to retract so that the pressure block 903 is tightened again, and put the cover 301 back on to continue use.

[0022] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
