Description

Technical Field

[0001] The present invention relates to the technical field of water pumps, in particular to an automatic pumping and filtering device for a swimming pool. Background Art

[0002] The automatic pump and filter device for swimming pools is an automated device that integrates a water pump and a filter. It is mainly used for the circulation, disinfection and purification of swimming pool water.

[0003] In the prior art, a Chinese patent document with the publication number CN211525109U proposes a high-dose metering pump for swimming pools that is easy to disassemble and clean. The invention proposes that due to the low pressure in the middle chamber, the drug fluid can be quickly sucked into the middle chamber. When the drug fluid is ejected, under the pressure of the pump core, the pressure in the middle chamber is relatively high and the amount of drug fluid is relatively large, so it can be ejected quickly, thereby improving the suction and ejection speed of the drug fluid, which is conducive to improving the drug administration efficiency of the metering pump, thereby realizing high-dose delivery of the metering pump, which is suitable for the disinfection of swimming pools. However, consistent with the traditional method, the traditional pump drug filtration device is in the process of swimming pool water treatment, although the filter element It is able to perform preliminary filtration on most particulate impurities, but there is still the problem that fine impurities enter the pipe with the medicine liquid and gradually settle at the bottom of the pipe during operation. Once these deposits accumulate, they are likely to form blockages inside the pipe, affecting the fluid flow and causing the system's medicine supply efficiency to decline. In addition, traditional devices mostly rely on manual regular shutdown to clean up the deposits, which is cumbersome to operate and requires high maintenance frequency, and can easily cause system interruptions or processing delays. Especially in unmanned or continuous operation scenarios, the stability is poor, and it is difficult to ensure continuous and accurate addition of medicine liquid.

[0018] Beneficial effects of the present invention:

[0019] 1. This type of automatic pump medicine filtration device for swimming pools is equipped with a bypass component and a terminal filter module. When the filtration system is blocked, the sliding blocking block automatically opens the bypass channel under the action of the pressure difference in the through pipe, ensuring uninterrupted drug supply. At the same time, the connecting rod driven by the linkage drives the movable filter plate to fit the fixed filter plate. The staggered matching of the filter holes and the ejection column structure realize the mechanical ejection self-cleaning function of the blocked particles, completing the online cleaning of the filter plate. This process is completely triggered by fluid pressure and responds automatically without the need for additional control components. It has a simple structure and a quick response. While improving the continuous operation capability of the system, it extends the service life of the filter plate, effectively reduces the maintenance frequency, and improves the overall operating efficiency and stability of the drug dosing system.

[0020] 2. This type of automatic pump medicine filtering device for swimming pools is equipped with first and second guide plates in conjunction with a bottom sand scraping module. Some granular impurities with strong sedimentation properties are gradually deposited in the area below the filter component as the medicine flows. Since two inclined guide plates are provided inside the through-tube, the particles carried by the liquid flow gradually slide down under the guidance of gravity and the inclination angle of the guide plates. The first guide plate is located directly below the filter plate, which can block the upper filter residue from continuing to fall back and prevent clogging the bottom of the filter element. The second guide plate is located on one side, guiding the impurities to concentrate and accumulate at the bottom of the through-tube. When the bypass component is automatically opened due to blockage, the connecting rod drives the scraper to move synchronously to the side of the liquid outlet cavity. The bottom of the scraper slides along the bottom surface close to the bottom of the through-tube, scraping away the deposited granular debris from under the guide plate and guiding them to the area with the slag discharge structure for subsequent unified discharge.

[0021] 3. This type of automatic pump medicine filtration device for swimming pools is equipped with a slag discharge module. The slag discharge module can effectively collect impurities swept away by the bottom sand scraping module by setting a sedimentation cylinder and an inclined bottom plate structure, thereby preventing them from backflowing and polluting the filtration system. At the same time, in conjunction with the first closing plate and the second closing plate arranged relatively on the slag discharge trough, a stable seal in the closed state and a synchronous opening at the moment of opening are achieved through multiple sets of springs and gear linkage structures, forming a short-time slag discharge channel. Under the high pressure of the pump body, the deposited impurities are quickly flushed out, ensuring high slag discharge efficiency and short response time without affecting the continuity of medicine supply. The core of the device lies in the cooperation between the driving rod and the trigger block linked to the connecting rod, so that the entire slag discharge action is automatically completed during the bypass closing and resetting process, without the need for independent control devices, and the structure is compact and the action is reliable.

[0035] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.

[0037] like Figures 1 to 11 As shown, the automatic medicine pump filtering device for a swimming pool includes a pump body 1 and a mounting base 4. A pump body water inlet pipe 2 is provided on one side of the pump body 1, and a pump body water outlet pipe 3 is provided on the top of the pump body 1; a filter component, the filter component is arranged above the mounting base 4, and one side of the filter component is connected to the pump body water inlet pipe 2, and the filter component is used to filter the medicine liquid; a bypass component, the bypass component is arranged on one side of the filter component, and the bypass component is used to assist in discharging medicine when the filter component is blocked; a cleaning component, the cleaning component is arranged inside the filter component, and the cleaning component includes a terminal filter module, a bottom sand scraping module, and a slag discharge module. The terminal filter module is used for tail-end filtration. And when the bypass component is turned on, it will simultaneously self-clean itself. The bottom sand scraping module is used to scrape the debris at the bottom of the filter component to the inside of the slag discharge module. The slag discharge module is used to drive the slag discharge module to be temporarily opened for slag discharge operation during the resetting of the bypass component after the filter component is normal. Among them, the filter component includes a through pipe 5 fixedly mounted on the top of the mounting seat 4, a filter 7 is provided above one side of the through pipe 5, and a filtered water inlet pipe 8 is provided above the filter 7. A threaded section 6 is provided on the outer surface of one side of the through pipe 5, and the through pipe 5 is connected to one side of the pump body 1 through the threaded section 6. A filter element 9 is provided inside the filter 7, and the filter element 9 is detachable and replaceable.

[0038] When the swimming pool water treatment system is started, the liquid medicine or medicine first enters the filter 7 set on the mounting seat 4 through the filter inlet pipe 8. The filter element 9 in the filter 7 performs preliminary filtration on the incoming liquid and intercepts particulate impurities. The filtered liquid medicine enters the water inlet pipe of the pump body 1 through the lower part of the through pipe 5, and is then pressurized by the pump body 1 and sent out from the water outlet pipe of the pump body 1 to the swimming pool system. During long-term operation, if the filter element 9 increases the water flow resistance or becomes blocked due to the accumulation of impurities, it can be removed for inspection and replacement. When the terminal filter module is blocked by impurities, the bypass component is automatically opened, and the medicine bypasses the terminal filter module and continues to be supplied from the bypass path to avoid system interruption or alarm due to blockage. The cleaning component starts to operate, and the terminal filter module performs synchronous reverse self-cleaning in the bypass open state. The bottom sand scraping module is started to mechanically scrape away the debris deposited at the bottom of the filter 7 and concentrate it in the slag discharge module. When the main filtration returns to normal and the bypass is closed, the slag discharge module is briefly opened to discharge the concentrated impurities out of the system.

[0039] like Figures 1 to 4 As shown, the bypass assembly includes a positioning shell 13 fixedly mounted on the side of the through pipe 5 away from the threaded section 6, one side of the positioning shell 13 is provided with a liquid inlet cavity 14 connected to the through pipe 5, and the inner side of the positioning shell 13 away from the through pipe 5 is provided with a liquid outlet cavity 17, a fixing rod 16 is fixedly mounted on the middle part of the positioning shell 13, and the fixing rod 16 is provided with a sliding blocking block 18 on the side close to the liquid inlet cavity 14, and the sliding blocking block 18 is provided with a first return spring 19 on the side away from the liquid inlet cavity 14, and the other end of the first return spring 19 is fixedly connected to the inner side of the liquid outlet cavity 17, and the sliding blocking block 18 is used to block the communication between the liquid inlet cavity 14 and the liquid outlet cavity 17, and a bypass liquid outlet 15 is provided on the side of the liquid outlet cavity 17, and a bypass pipe 21 is provided on the other side of the bypass liquid outlet 15, and a bypass liquid inlet 22 is provided on the side of the through pipe 5 away from the positioning shell 13, and the other end of the bypass pipe 21 is connected to the bypass liquid inlet 22;

[0040] When the system is operating normally, the pump body 1 sucks in the medicine liquid and filters it through the filter assembly. The filtered liquid flows into the pump body 1 through the through pipe 5. When blockage occurs and the liquid inlet is blocked, the liquid generates back pressure in the through pipe 5, which pushes the sliding blocking block 18 to move along the fixed rod 16 toward the liquid outlet cavity 17, compressing the first return spring 19, so that the originally blocked liquid inlet cavity 14 is connected with the liquid outlet cavity 17, and the medicine can enter the bypass pipe 21 through the bypass liquid outlet 15, and enter the through pipe 5 downstream again through the bypass liquid inlet 22, bypassing the main filtering path to continue supplying medicine, ensuring that the pump body 1 does not interrupt the liquid supply. When the filter element 9 is cleared, the through pipe 5 is restored to normal, the flow rate of the main path returns to normal, the pressure drops, and the first return spring 19 pushes the sliding blocking block 18 back to its position, re-closing the bypass channel, and returning the system to the main filtering path.

[0041] like Figure 3 、 Figure 7 As shown, the terminal filter module includes a fixed filter plate 10 fixedly mounted on the side of the through-tube 5 away from the positioning housing 13, and a movable filter plate 11 slidably mounted on the side of the through-tube 5 away from the positioning housing 13. The fixed filter plate 10 and the movable filter plate 11 are arranged one after the other, and the fixed filter plate 10 and the movable filter plate 11 are both arranged at an angle. A connecting rod 20 is fixedly connected to the side of the sliding blocking block 18 away from the first return spring 19. The connecting rod 20 passes through the fixed filter plate 10 and is fixedly connected to one side of the movable filter plate 11. The filter holes on the fixed filter plate 10 and the movable filter plate 11 are staggered. The opposite surfaces of the fixed filter plate 10 and the movable filter plate 11 are provided with ejector posts 12, and a plurality of ejector posts 12 respectively correspond to the filter holes on the fixed filter plate 10 or the movable filter plate 11.

[0042] When the filter assembly has been running for a long time and the filter element 9 or filter plate is blocked and the flow rate of the through pipe 5 is reduced, the system pressure rises and the sliding blocking block 18 is pushed to overcome the elastic force of the first return spring 19 to slide to the side of the liquid outlet cavity 17, opening the bypass path. At the same time, the integrated connecting rod 20 connected to it moves forward synchronously, driving the movable filter plate 11 to move closer to the fixed filter plate 10. Due to the staggered distribution of the filter holes of the two filter plates, the two gradually fit together. At this time, the several ejector posts 12 placed on the surface of the filter plate begin to enter the holes of the other filter plate. Under the action of mechanical top pressure, the blocked particles are forcibly ejected from the holes, completing the terminal self-cleaning action. After the cleaning is completed, when the system is restored to normal and the pressure drops, the sliding blocking block 18 returns to its original position under the action of the return spring, and the connecting rod 20 and the movable filter plate 11 also return to their original positions, restoring the normal filtering structure state. The entire action is completed by the pressure difference linkage when the bypass is enabled, and no external energy consumption control is required.

[0043] like Figure 3 、 Figure 5 As shown, the interior of the through pipe 5 is further staggered with inclined first guide plates 39 and second guide plates 40. The first guide plate 39 is located directly below the filter assembly, and the second guide plate 40 is located on the lower side of the filter assembly. The first guide plate 39 and the second guide plate 40 are arranged one above the other. The bottom sand scraping module includes a scraper 41 that is tightly attached to one side of the first guide plate 39, and the scraper 41 is fixedly sleeved on the side of the connecting rod 20 away from the positioning housing 13. The bottom of the scraper 41 is tightly attached to the bottom of the through pipe 5, and the top of the scraper 41 is set as an inclined surface to reduce impurities from falling between the first guide plate 39 and the scraper 41.

[0044] During the operation of the swimming pool liquid filtration system, some granular impurities with strong sedimentation properties gradually settle in the area below the filter assembly as the liquid flows. Since two inclined guide plates are provided inside the through-pipe 5, the particles carried by the liquid flow gradually slide down under the guidance of gravity and the inclination angle of the guide plates. The first guide plate 39 is located directly below the filter plate, which can block the upper filter residue from continuing to fall back and prevent clogging the bottom of the filter element 9, while the second guide plate 40 is located on one side, guiding the impurities to concentrate and accumulate at the bottom of the through-pipe 5. When the bypass assembly is automatically opened due to blockage, the connecting rod 20 drives the scraper 41 to move synchronously toward the side of the liquid outlet cavity 17. The bottom of the scraper 41 slides along the bottom surface close to the bottom of the through-pipe 5, scraping off the deposited granular debris from the bottom of the guide plate and guiding them to the area where the slag discharge structure is provided for subsequent unified discharge.

[0045] like Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 As shown, the slag discharge module includes a deposition cylinder 23 arranged between the through pipe 5 and the bypass assembly, and the deposition cylinder 23 is sunken, and a bottom plate 24 inclined toward the middle is provided at the bottom of the deposition cylinder 23, and a rectangular slag discharge trough 25 is provided in the middle of the bottom plate 24, and a chute is provided on both sides of the slag discharge trough 25, and a first closing plate 26 and a second closing plate 27 are slidably installed in the chute, and a side of the first closing plate 26 and the second closing plate 27 away from each other is provided with a plurality of second return springs 29, and the plurality of second return springs 29 are respectively fixedly connected to a side of the chute away from the slag discharge trough 25, and the opposing surfaces of the first closing plate 26 and the second closing plate 27 are arranged in inclined surfaces that fit each other, and a fixing seat 36 is fixedly installed in the middle of the top surface of the first closing plate 26, and a trigger block 37 is slidably installed inside the fixing seat 36, and the bottom surface of the trigger block 37 is fixedly connected to a plurality of third A return spring 38, the bottom surface of the third return spring 38 is fixedly connected to the inner bottom surface of the fixed seat 36, and both sides of the top surface of the trigger block 37 are set to an inclined shape. A driving rod 28 is also fixedly sleeved on the middle part of the connecting rod 20, and the initial position of the driving rod 28 is located in the direction close to the scraper 41. A first extension plate 30 is provided on one side of the first closing plate 26, and a plurality of first meshing teeth 31 are provided on one side of the bottom of the first extension plate 30. A second extension plate 32 is provided on one side of the second closing plate 27, and a second meshing tooth 33 is provided on one side of the second extension plate 32. A positioning rod 34 is also provided on one side of the inner side of the bottom plate 24, and a gear 35 is provided on one side of the positioning rod 34. The upper part of the gear 35 is meshed with the first meshing teeth 31, and the lower part of the gear 35 is meshed with the second meshing teeth 33. When the first extension plate 30 moves, it will drive the second extension plate 32 to move in the opposite direction.

[0046] After the swimming pool pump and filter device has been running for a long time, impurities scraped off by the bottom sand scraping module will gradually accumulate in the bottom sedimentation cylinder 23. At this time, if the bypass is triggered to open, the connecting rod 20 drives the driving rod 28 to move synchronously toward the liquid outlet cavity 17. During the movement toward the liquid outlet cavity 17, the driving rod 28 first squeezes the trigger block 37. Since the first closing plate 26 and the second closing plate 27 are in a close fit at this time, the squeezing force will only drive the first closing plate 26 to squeeze the second closing plate 27. In this squeezing direction, the first closing plate 26 will not be pushed to squeeze the second closing plate 27 to open. Only the two closing plates will be squeezed. The closure plate 36 is in the closed position, and the first closing plate 26 is in the closed position, so that the first closing plate 2 ... The first closure plate 26 is moved to open and close, so the driving rod 28 first presses against the inclined surface to drive the trigger block 37 to drive the first closing plate 26 to move, and at the same time pushes the first closing plate 26 connected thereto to open. At the same time, the gear 35 starts to rotate under the action of the first meshing tooth 31, and drives the second meshing tooth 33 meshing therewith to make the second closing plate 27 open synchronously in the opposite direction, forming a short slag discharge channel. Since the sedimentation cylinder 23 is connected to the pump body 1, the high-pressure liquid of the pump body 1 impacts the slag discharge groove 25 at the moment of opening, and is quickly ejected with impurities, realizing a short-term slag discharge function. When 20 continues to reset to the initial position, the driving rod 28 disengages from the trigger block 37, and the trigger block 37 returns to its original position under the action of the third reset spring 38. The first closing plate 26 and the second closing plate 27 are quickly closed under the drive of the second reset spring 29 to block the slag discharge trough 25. During this process, the torsion spring structure provided on the second closing plate 27 pulls the closing plate to tilt and rotate when opening. When the closing plate is closed, its inclined edge first contacts the surface of the first closing plate 26, and slides and resets along its inclined surface during the continued closing process, thereby automatically scraping off impurities thereon and improving the cleanliness and sealing effect of the closed interface.

Within the scope of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
