Description

Technical Field

[0001] This utility model relates to the field of air source heat pump water storage technology, specifically a water storage tank for an air source heat pump. Background Technology

[0002] An air source heat pump is an energy-saving device that uses high-grade energy to move heat from a low-grade heat source (air) to a high-grade heat source. It is a type of heat pump. As the name suggests, a heat pump, like a pump, can convert low-grade heat energy (such as the heat contained in air, soil, and water) that cannot be directly used into usable high-grade heat energy, thereby saving some high-grade energy (such as coal, gas, oil, and electricity). Because the circulating water volume in the air source heat pump system loop is limited, the main unit reaches the set temperature in a very short time, then stops working, and then starts again in a very short time when the water temperature reaches the main unit's startup conditions. This frequent starting of the main unit greatly reduces its lifespan, and the main unit consumes the most electricity during startup, thus increasing energy consumption. Therefore, current air source heat pumps are used in conjunction with a water storage tank. The water storage tank increases the system's water capacity, stabilizes system temperature changes, reduces the number of main unit startups, and extends its lifespan.

[0003] Because air source heat pumps are closed-loop systems, impurities will appear in the water in the pipes. When the water flows into the storage tank, these impurities will accumulate at the bottom. Existing storage tanks for air source heat pumps have the following shortcomings: 1. The method of simply relying on sedimentation to allow solid impurities to settle at the bottom is easily disturbed by the water flow, resulting in a lack of a stable mechanism to directly confine solid impurities to the bottom, leading to poor stability. 2. When the water quality in some areas is poor, impurities will accumulate rapidly in the storage tank, requiring frequent cleaning. Since the drain valve at the bottom of the storage tank is directly connected to the entire tank body, draining often requires draining all the water inside, making it difficult to clean the accumulated impurities at the bottom separately, resulting in poor convenience and efficiency in draining. In view of this, this application proposes a storage tank for air source heat pumps to solve the above-mentioned problems. Utility Model Content

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. By using the water inlet pipe, isolation plate, first through hole, second through hole and stainless steel filter screen, solid residue and impurities in the water can be directly filtered, intercepted and blocked at the bottom of the tank when water is supplied for storage.

[0023] 3. Replacing the air pump with a water pump can backwash and clean the stainless steel filter screen during sewage discharge. The water spray cleaning method can better clean the bottom of the tank when the water is sprayed into the bottom of the tank and creates an impact and scattering effect inside, resulting in a better cleaning effect. The air pump cleaning method has a better water-saving effect. Both methods can be flexibly selected by the personnel.

[0024] This utility model, through a series of structures, can directly filter, intercept, and confine solid waste and impurities in the water to the bottom of the tank when water is supplied for storage. This prevents solid waste from entering the upper part and floating around during water intake and output, thus affecting water flow and improving operational stability. It also facilitates convenient and quick discharge of impurities intercepted below the isolation plate and backflushing to clean and unclog the stainless steel filter screen. Furthermore, by using a horizontal barrier isolation method, it is not necessary to completely drain the water stored inside during cleaning, saving water resources and providing convenience for cleaning work. This improves the convenience and efficiency of sewage discharge and conserves water resources. Attached Figure Description

[0030] 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.

[0031] Example 1

[0032] like Figures 1 to 3 As shown in the figure, the water storage tank for an air source heat pump proposed in this embodiment includes:

[0033] Tank 1 has three L-shaped supports fixedly connected to its bottom in a triangular shape, a drain valve 102 fixedly connected to its bottom, a water outlet pipe fixedly connected to its left bottom, and a cover plate fixedly installed on its top.

[0034] The inlet pipe 101 is embedded and fixed on the top left side of the cover plate, and the top end of the inlet pipe is connected to and fixed with an inlet valve; the inlet pipe 101 is used to connect to the water supply pipe of the external air source heat pump circulation system through the inlet valve to introduce hot water.

[0035] The isolation plate 2 is fixedly installed inside the tank 1 and located below the water outlet pipe. The top of the isolation plate 2 has a first through hole 201 and a second through hole 202. The bottom end of the water inlet pipe 101 is fixedly connected to the top of the isolation plate 2 and vertically aligned with the first through hole 201. The right side of the isolation plate 2 has a rectangular groove 204 that intersects and communicates with the second through hole 202. The first through hole 201 is used to supply hot water into the space below the isolation plate 2 when hot water is supplied. As water is continuously supplied, the water level rises and enters the water storage space above the isolation plate 2 through the second through hole 202.

[0036] A stainless steel filter screen 203 is fixedly installed inside the second through hole 202; the stainless steel filter screen 203 is used to directly filter and intercept solid particles and impurities in the water when water flows in from bottom to top through the second through hole 202.

[0037] U-shaped support 4 is fixedly connected to the right side of tank body 1;

[0038] The transverse guide and transverse drive assembly is installed at the bottom right side of the tank 1 and is located inside the U-shaped support 4;

[0039] The flow-through horizontal sealing back-blowing cleaning assembly is fitted inside the rectangular groove 204 and fixedly connected to the bottom of the horizontal guide and drive assembly. The bottom end of the flow-through horizontal sealing back-blowing cleaning assembly is connected to and fixedly connected to the explosion-proof hose 303 located in the U-shaped support 4.

[0040] The flow supply device is installed on the inner wall of the bottom of the U-shaped support 4 and is connected and fixed to the explosion-proof hose 303; the horizontal guide and horizontal drive assembly is used to drive the flow-through horizontal sealing back-blowing cleaning assembly to move horizontally left and right to perform horizontal blocking or unblocking work on the second through hole 202. The horizontal blocking is used to achieve horizontal sealing and isolation of the water storage space above the isolation plate 2. The flow-through horizontal sealing back-blowing cleaning assembly is used to discharge the impurities intercepted below the isolation plate 2 and to reverse clean and dredge the stainless steel filter screen 203 when the drain valve 102 and the flow supply device are opened.

[0041] Furthermore, the supply device is an air pump 5, which is fixedly installed on the bottom inner wall of the U-shaped support 4. The air outlet of the air pump 5 is connected and fixed to the bottom end of the explosion-proof hose 303. The air pump 5 is used to supply gas medium through the explosion-proof hose 303 to provide a backflushing cleaning and unblocking effect.

[0042] Furthermore, such as Figure 1 and 2 As shown, the transverse guide drive assembly includes two transverse guide rods 402, a movable plate 401, and a multi-stage electric telescopic rod 403. The two transverse guide rods 402 are fixedly connected to the bottom right side of the tank body 1. The movable plate 401 is located inside the U-shaped support 4 and is slidably sleeved on the two transverse guide rods 402. The multi-stage electric telescopic rod 403 is embedded and fixed on the inner right side of the U-shaped support 4. The extended end of the multi-stage electric telescopic rod 403 is fixedly connected to the right side of the movable plate 401.

[0043] In this embodiment, two horizontal guide holes are provided on the right side of the movable plate 401, which are respectively slidably fitted to the outer side of the corresponding horizontal guide rod 402, so as to guide the movable plate 401 to slide laterally.

[0044] In this embodiment, the two horizontal guide rods 402, the movable plate 401 and the multi-stage electric telescopic rod 403 work together to drive the movable plate 401 to slide to the left or move back to the right on the two horizontal guide rods 402.

[0045] Furthermore, such as Figure 2 and 3 As shown, the flow-through horizontal sealing backflush cleaning assembly includes an L-shaped tube 302 and a box-shaped sealing plate 3. The box-shaped sealing plate 3 is slidably fitted inside the rectangular groove 204. Multiple blow holes 301 are opened at the bottom center of the box-shaped sealing plate 3. The multiple blow holes 301 are all located on the upper right side of the stainless steel filter screen 203 and cooperate with it. The L-shaped tube 302 is connected and fixed to the right side of the box-shaped sealing plate 3. The tank body 1 is slidably fitted on the L-shaped tube 302. The bottom end of the L-shaped tube 302 is connected and fixed to the top end of the explosion-proof hose 303. The top right side of the L-shaped tube 302 is fixedly connected to the bottom of the movable plate 401.

[0046] In this embodiment, the outer side of the box-shaped sealing plate 3 is covered with a sealing rubber, and the outer side of the sealing rubber slides in contact with the inner wall of the rectangular groove 204. The bottom of the sealing rubber has multiple connecting holes that are connected to the corresponding blow holes 301, which achieves the effect of sliding seal between the outer side of the box-shaped sealing plate 3 and the inner side of the rectangular groove 204. A through hole is provided on the inner wall of the right side of the tank body 1, and two sealing rings are bonded and fitted in the through hole. The inner side of the sealing ring slides in contact with the outer side of the L-shaped tube 302, which achieves the effect of lateral sliding seal of the L-shaped tube 302.

[0047] In this implementation scheme, the L-shaped tube 302, the blowhole 301, and the box-shaped sealing plate 3 work together. When the moving plate 401 moves to the left or back to the right, it drives the L-shaped tube 302 to move to the left or back to the right. The L-shaped tube 302 drives the top end of the explosion-proof hose 303 to move laterally. When the L-shaped tube 302 moves to the left, it drives the box-shaped sealing plate 3 to slide to the left within the rectangular groove 204, blocking the second through hole 202. The box-shaped sealing plate 3 drives multiple blowholes 301 to move to the left above the stainless steel filter screen 203. When the L-shaped tube 302 moves back to the right, it drives the box-shaped sealing plate 3 to the right to unseal the second through hole 202, achieving a convenient and quick effect of blocking or unsealing the second through hole 202. When the horizontal barrier is blocked, and when the gas medium is supplied through the explosion-proof hose 303, the gas is supplied into the box-shaped sealing plate 3 through the L-shaped pipe 302. At this time, the gas blows downward through multiple blowholes 301 to back-blown clean and unclog the stainless steel filter screen 203. In the isolated state, when the personnel open the drain valve 102, some water below the isolation plate 2 mixed with impurities that have been filtered and deposited at the bottom is discharged downward. The impurities cleaned by back-blowing are also discharged downward. This achieves the effect of conveniently and quickly draining the impurities intercepted below the isolation plate 2 and back-blowing clean and unclog the stainless steel filter screen 203. Moreover, by using the horizontal barrier isolation method, it is not necessary to release all the water stored inside during cleaning, saving water resources and providing convenience for the cleaning work.

[0048] It should be noted that the isolation plate 2 is made of stainless steel. Stainless steel has the advantages of high hardness, strong corrosion resistance and good maintenance-free performance, which ensures long-term application stability.

[0049] For 203 stainless steel filter screens, a mesh size of at least 60 is preferred.

[0050] The inner side of the sealing ring makes close contact with the outer side of the L-shaped tube 302 to achieve a sealed installation.

[0051] It should be noted that a control switch is fixedly installed on the front of the multi-stage electric telescopic rod 403, and an on / off switch is fixedly installed on the front of the air pump 5, and they are directly electrically connected via flexible wires. Regarding power supply, given that the air source heat pump is used in a fixed heating application environment, there is no shortage of mains power supply. Both electrical components of this device are connected to the mains power supply and are connected to the power input interfaces of each device through conventional power distribution devices (not marked in the figure), such as circuit breakers, contactors, and power modules, to form a complete power supply circuit. This power supply scheme adopts the conventional power distribution and switch operation wiring method of industrial equipment, which is a conventional and mature known technology in this field and will not be described in detail here.

[0052] This embodiment can directly filter, intercept, and confine solids and impurities in the water to the bottom of the tank 1 when water is supplied for storage. This prevents solids and impurities from entering the upper part of the tank during water intake and output, causing them to float and sink and affect water flow, thus improving the stability of use. It also facilitates the quick and easy removal of impurities trapped below the isolation plate 2 and the backflushing cleaning and unblocking of the stainless steel filter screen 203. Furthermore, by using a horizontal barrier isolation method, it is not necessary to completely drain the water stored inside during cleaning, saving water resources and providing convenience for cleaning work. This improves the convenience and efficiency of sewage discharge and saves water resources.

[0053] The usage method of this embodiment is as follows: When the water storage tank for the air source heat pump is in use, the inlet pipe 101 is used to connect to the external air source heat pump circulation system water supply pipeline through the inlet valve to supply hot water. The outlet pipe is connected to the external water supply pipeline. The water directly enters the position below the isolation plate 2 through the first through hole 201. As the water is continuously supplied, the water level rises and passes through the stainless steel filter screen 203 and enters the water storage space above the isolation plate 2 through the second through hole 202 for water storage. When the water passes through the stainless steel filter screen 203, the stainless steel filter screen 203 directly filters, intercepts and blocks the solid residue impurities in the water and restricts them below the isolation plate 2, thereby achieving the effect of directly restricting the solid residue impurities at the bottom of the tank 1. This prevents the solid residue from entering the upper part and sinking and floating during water inlet and outlet, affecting the water flow and improving the stability of use.

[0054] During subsequent cleaning and sewage discharge, the multi-stage electric telescopic rod 403 is activated in the forward direction, causing the moving plate 401 to slide to the left on the two horizontal guide rods 402. The moving plate 401 drives the L-shaped tube 302 to move to the left, which in turn drives the top of the explosion-proof hose 303 to move laterally. The L-shaped tube 302 also drives the box-shaped sealing plate 3 to slide to the left within the rectangular groove 204, blocking the second through hole 202. The box-shaped sealing plate 3 drives multiple blowholes 301 to move to the left above the stainless steel filter screen 203. Personnel start the air pump 5 and open the sewage discharge valve 102, while closing the water inlet valve. Some water below the isolation plate 2, mixed with impurities filtered and deposited at the bottom, is discharged downwards. A sewage collection box or an external sewage discharge pipe can be placed below the sewage discharge valve 102. When the air pump 5 is started, air is supplied to the L-shaped tube 302 through the explosion-proof hose 303, and the air then enters the box-shaped sealing plate 302. Inside plate 3, gas flows downward through multiple blowholes 301 to backflush and clean the stainless steel filter screen 203. The impurities cleaned by the backflush are discharged downward through the drain valve 102. This achieves the effect of conveniently and quickly draining the impurities trapped below the isolation plate 2 and backflush and cleaning the stainless steel filter screen 203. Moreover, by using the horizontal barrier isolation method, it is not necessary to completely drain the water stored inside during cleaning, saving water resources and providing convenience for the cleaning work. This improves the convenience and efficiency of sewage discharge and saves water resources. After sewage discharge, personnel close the drain valve 102 and the air pump 5, open the water inlet valve, and start the multi-stage electric telescopic rod 403 in reverse. At this time, the multi-stage electric telescopic rod 403 drives the L-shaped tube 302 to move back to the right through the moving plate 401. The L-shaped tube 302 drives the box-shaped sealing plate 3 to the right to unseal the second through hole 202, so that water flow and filtration restriction work can continue.

[0055] Example 2

[0056] Reference Figure 4 As shown, this embodiment differs from Embodiment 1 in that: the water supply device is a water pump 501, which is fixedly installed on the inner wall of the bottom of the U-shaped support 4. The outlet of the water pump 501 is connected and fixedly connected to the bottom end of the explosion-proof hose 303, and the inlet of the water pump 501 is connected and fixedly connected to the suction hose 502. The water pump 501 is used to supply liquid medium through the explosion-proof hose 303 to provide a backflushing cleaning and unblocking effect.

[0057] It should be noted that a switch is fixedly installed on the front of the water pump 501, and a direct electrical connection is achieved through a flexible wire. Given that the air source heat pump is used in a fixed heating application site, and there is no shortage of mains power supply, the above-mentioned electrical components of this device are connected to the mains power supply and connected to the power input interface of each device through conventional power distribution devices such as circuit breakers, contactors, and power modules (not marked in the figure) to form a complete power supply circuit. This power supply scheme adopts the conventional power distribution and switch operation wiring method of industrial equipment, which is a conventional and mature known technology in this field, and will not be described in detail here.

[0058] In this embodiment, by using a water pump 501 instead of an air pump 5, the stainless steel filter screen 203 can be backflushed and cleaned during sewage discharge. By using water spray cleaning, when water is sprayed into the bottom of the tank 1 and forms an impact and scattering inside, the bottom can be cleaned better.

[0059] The usage method of this embodiment is as follows: The difference from Embodiment 1 is that it also has the following functions: The water pump 501 is used to replace the air pump 5 in another way. When the water suction hose 502 is connected to the external water source, the water pump 501 is started to draw the external water source through the water suction hose 502 and supply it into the box-shaped sealing plate 3 in sequence through the explosion-proof hose 303 and L-shaped pipe 302. The water is sprayed downward through multiple blow holes 301 to backwash and clean the stainless steel filter screen 203. By using the water backwash cleaning method, when the water is sprayed into the bottom of the tank 1 and forms an impact and scattering inside, the bottom can be cleaned better and the cleaning effect is better. The air pump 5 air supply cleaning method has a better water-saving effect. The two methods can be flexibly selected by the personnel.

[0060] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
