Description

Technical Field

[0001] This invention relates to the field of water purification technology, specifically to a water purification treatment device for a secondary water supply tank. Background Technology

[0002] Secondary water supply tanks are used to store domestic water supplied by the municipal water supply network and then pressurize it to deliver it to users' homes, thus providing secondary water supply for high-rise users. After long-term use, impurities may accumulate in the municipal water supply network and the secondary water supply tank. If not treated in time, these impurities may be transported to users' homes with the domestic water, causing harm to their health. Therefore, it is necessary to purify the water in the secondary water supply tank.

[0003] Publication No. CN120271085A discloses a water purification treatment device for a secondary water supply tank. By setting up a backup pipe and initially sealing it with a second filter assembly, the frequency of backup pipe usage can be greatly reduced. During peak water usage periods, the water pump's output power increases, and the water pressure in the main pipeline increases. The water flow pushes the sealed inner pipe through the second filter assembly, exposing the inlet end of the backup pipe. Some water passes through the backup pipe, increasing the water flow while preventing a reduction in filtration efficiency. By setting multiple activated carbon plates, multiple filtrations can be performed on the water, improving the filtration and purification effect. The multiple activated carbon plates are connected by a second return spring. During backwashing, the tension spring and the second return spring cause the multiple activated carbon plates to vibrate back and forth, accelerating the removal of impurities from the activated carbon plates and improving the backwashing efficiency. However, this patent still has the following problems in actual use:

[0004] This secondary water supply tank water purification equipment uses multiple activated carbon plates for multi-stage filtration, improving the water filtration and purification effect. The activated carbon plates are connected by a second return spring. During backwashing, the tension spring and the second return spring cause the activated carbon plates to vibrate back and forth, accelerating the removal of impurities and improving the backwashing efficiency. However, the size of the activated carbon plates is limited. When impurities adhere to the filter, it affects the adsorption effect of the activated carbon plates. When a certain amount of impurities adhere to the filter, the contact area between the activated carbon plates and the water decreases, thus affecting the water purification effect. Furthermore, the inability to filter and remove hard objects and other impurities not only affects the water filtration effect but also damages the pump impeller, increasing equipment maintenance costs.

[0005] Therefore, a water purification device for secondary water supply tanks is proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a water purification device for secondary water supply tanks, addressing the limitations of activated carbon plates in the prior art. These limitations include the limited size of the activated carbon plates, which, when used for water filtration, can affect adsorption efficiency when impurities adhere to the filter. Furthermore, the presence of impurities reduces the contact area between the activated carbon plates and the water, thus impacting purification. Additionally, the inability to filter and remove hard objects and other impurities not only affects filtration but also damages the pump impeller, increasing maintenance costs.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: This water purification treatment device for a secondary water supply tank utilizes an internal filter cylinder to filter larger particulate impurities. Simultaneously, the internal filter cylinder drives the first connecting bracket and the outer filter cylinder to rotate, allowing the outer filter cylinder to filter smaller particulate impurities. The adsorption filter media inside the outer filter cylinder adsorbs and filters the water, thus achieving water purification. The rotation ensures the adsorption filter media fully adsorbs the water flow, improving the adsorption effect. Meanwhile, the fixed connecting rod and cleaning scraper remain stationary. When the internal filter cylinder rotates, the cleaning scraper cleans impurities adhering to the inner wall of the internal filter cylinder, preventing clogging and ensuring effective filtration. The impeller accelerates the water flow, achieving a pressurization effect. The filter screen cylinder performs secondary filtration, filtering out impurities such as limescale from the water flow, preventing limescale adsorption on the impeller and thus affecting its rotation. The specific details are as follows:

[0022] 1. By setting up an adsorption filtration mechanism, not only can the first rotating motor drive the first rotating disk and rotating connecting rod to rotate, causing the rotating connecting rod to drive the first rotating ring and the inner filter cylinder to rotate, the inner filter cylinder can filter larger particulate impurities. Simultaneously, the inner filter cylinder drives the first connecting bracket and the outer filter cylinder to rotate, allowing the outer filter cylinder to filter smaller particulate impurities. The adsorption filter media inside the outer filter cylinder can adsorb and filter water, thus achieving the effect of water purification. Since the first outlet pipe of the water storage tank is located at the bottom, the water flows towards the bottom, causing a greater accumulation of impurities at the bottom of the inner and outer filter cylinders. The rotation mechanism not only prevents impurities from accumulating in one place in the inner and outer filter cylinders, but also... The system enhances the filtration efficiency of both the internal and external filter cartridges. Rotation allows the filter media to fully adsorb water flow, improving adsorption. Meanwhile, the fixed connecting rod and cleaning scraper remain stationary. As the internal filter cartridge rotates, the cleaning scraper removes impurities adhering to its inner wall, preventing blockage and ensuring optimal filtration. To clean the internal filter cartridge, the first drain pipe is opened, and the backwash pipe is connected. The water flow discharges impurities from the internal filter cartridge through the first drain pipe, while small particles from the inner wall of the external filter cartridge enter the internal filter cartridge and are discharged through the first drain pipe, thus improving the overall filtration efficiency of both cartridges.

[0023] 2. By setting up a water pump protection mechanism, the drive motor can rotate the second rotating disc, connecting outer ring, impeller, and connecting inner ring. The impeller accelerates the water flow, thus achieving a pressurization effect. The filter screen can perform secondary filtration on the return flow, filtering out impurities such as limescale in the water flow and preventing limescale from adhering to the impeller, which would affect the impeller's rotation efficiency. When cleaning the filter screen is required, the second rotating motor is started to drive the rotating worm gear. Utilizing the meshing connection between the rotating worm gear and the rotating worm wheel, the rotating worm wheel drives the second rotating ring and the cleaning spiral blade to rotate. The cleaning spiral blade can clean the impurities attached to the surface of the filter screen and open the second drain pipe. Under the action of water flow, impurities can be discharged from the inside of the pump pipe, thereby improving the service life of the pump pipe. By setting up two sets of drive motors, the water pressure can be automatically adjusted when the water pressure is insufficient, thereby meeting the water demand. At the same time, the water flow can be filtered and purified, thereby improving water quality. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-4The present invention provides a technical solution: a water purification device for a secondary water supply tank, comprising an adsorption filtration mechanism 1 and a first outlet pipe 119 installed at the bottom of the adsorption filtration mechanism 1. A water pump protection mechanism 2 is provided on one side of the adsorption filtration mechanism 1, and a drive motor 208 is provided on the top of the water pump protection mechanism 2. The adsorption filtration mechanism 1 includes a water storage tank 101, a fixing cover 102 is fixedly installed on one side of the water storage tank 101, a first drain pipe 103 is fixedly installed on one side of the fixing cover 102, and a first rotating motor 104 is fixedly installed on the outside of the fixing cover 102. The output end of the first rotating motor 104 is fixedly connected to a first rotating disk 105, and a rotating connecting rod 106 is fixedly connected to one side of the first rotating disk 105. A first rotating ring 1 is fixedly installed at the end of the rotating connecting rod 106. 07. An internal filter cylinder 108 is fixedly installed on one side of the first rotating ring 107. Several first connecting brackets 109 are fixedly installed on the outside of the internal filter cylinder 108. An external filter cylinder 110 is fixedly installed at the end of the first connecting bracket 109. The first rotating motor 104 drives the first rotating disk 105 and the rotating connecting rod 106 to rotate, so that the rotating connecting rod 106 drives the first rotating ring 107 and the internal filter cylinder 108 to rotate. The internal filter cylinder 108 can filter larger particulate impurities. At the same time, the internal filter cylinder 108 drives the first connecting bracket 109 and the external filter cylinder 110 to rotate, so that the external filter cylinder 110 can filter small particulate impurities. The adsorption filter material 124 inside the external filter cylinder 110 can adsorb and filter water, thereby achieving the effect of purifying water.

[0038] Please see Figures 3-6 A fixing ring 111 is rotatably connected to the end of the internal filter cylinder 108. A first water inlet pipe 112 is fixedly installed on one side of the fixing ring 111. A first fixing bracket 113 is fixedly installed inside the fixing ring 111. A fixing connecting rod 114 is fixedly installed on one side of the first fixing bracket 113. Several cleaning scrapers 115 are fixedly installed on the outside of the fixing connecting rod 114. The cleaning scrapers 115 are in close contact with the inner wall of the internal filter cylinder 108. Since the first water outlet pipe 119 of the water storage tank 101 is located at the bottom, the water will flow towards the bottom. Therefore, impurities at the bottom of the internal filter cylinder 108 and the outer filter cylinder 110 will accumulate. The internal filter cartridge 108 and the external filter cartridge 110 are relatively large. By rotating the cartridge, impurities can be prevented from accumulating in one place on the internal filter cartridge 108 and the external filter cartridge 110, thus affecting the filtration effect of the internal filter cartridge 108 and the external filter cartridge 110. The rotation also allows the adsorption filter media 124 to fully adsorb the water flow, improving the water flow adsorption effect. At the same time, the fixed connecting rod 114 and the cleaning scraper 115 are fixed in place. When the internal filter cartridge 108 rotates, the cleaning scraper 115 is used to clean the impurities adhering to the inner wall of the internal filter cartridge 108, preventing impurities from clogging the internal filter cartridge 108 and thus affecting the filtration effect of the internal filter cartridge 108.

[0039] Please see Figures 5-6 A second fixed bracket 116 is fixedly installed on the side of the fixed connecting rod 114 away from the first fixed bracket 113. The second fixed bracket 116 is rotatably connected to the first rotating ring 107. A maintenance box cover 117 is fixedly installed on the outer side of the fixed ring 111. Several fixing bolts 118 are threadedly connected to the inner and outer sides of the maintenance box cover 117.

The outer filter cylinder 110 is equipped with adsorption filter media 124. When it is necessary to clean the impurities inside the inner filter cylinder 108, the first drain pipe 103 is opened and the backwash pipe 120 is connected at the same time. Under the action of water flow, the impurities inside the inner filter cylinder 108 can be discharged through the first drain pipe 103. At the same time, small particles of impurities on the inner wall of the outer filter cylinder 110 enter the inner filter cylinder 108 and are discharged through the first drain pipe 103, thereby improving the filtration effect of the inner filter cylinder 108 and the outer filter cylinder 110.

[0040] Please see Figures 7-9The pump protection mechanism 2 includes a first connecting pipe 201, which is fixedly connected to a first outlet pipe 119.

Second connecting brackets 206 are fixedly installed around the top of the bottom fixing seat 205. A supporting top plate 207 is fixedly installed on the top of the second connecting brackets 206. A drive motor 208 is fixedly installed on the top of the supporting top plate 207. A top fixing plate 209 is fixedly installed on the inner side of the top of the pump pipe 203. A top fixing plate 209 is fixedly installed on the inner side of the bottom of the pump pipe 203. The device is equipped with a bottom fixed plate 210, and a filter screen 211 is fixedly installed between the top fixed plate 209 and the bottom fixed plate 210. The output end of the drive motor 208 is fixedly connected to a second rotating plate 212. The bottom of the second rotating plate 212 is provided with several connecting outer rings 213, and impellers 214 are fixedly connected between the connecting outer rings 213. The drive motor 208 drives the second rotating plate 212, the connecting outer rings 213, the impellers 214 and the connecting inner rings 215 to rotate. The impellers 214 can accelerate the flow of water, thereby achieving a pressurization effect. The filter screen 211 can perform secondary filtration of the water flow, filtering out impurities such as water scale in the water flow, and preventing water scale from adsorbing on the impellers 214, thus affecting the rotation effect of the impellers 214.

[0041] Please see Figures 9-11An inner connecting ring 215 is fixedly installed on the inner side of the impeller 214, and an outer connecting ring 213 is rotatably connected to the bottom fixed plate 210. A second rotating ring 216 is rotatably connected to the outer side of the bottom fixed plate 210. A cleaning spiral blade 217 is fixedly installed on the top of the second rotating ring 216.

A support ring 226 is symmetrically installed on the outer side of the second connecting pipe 224, and a support column 227 is fixedly installed at the bottom of the support ring 226. A sealing cover 228 is fixedly installed on the side of the second connecting pipe 224 away from the connecting flange 225. When the filter screen cylinder 211 needs to be cleaned, the second rotating motor 219 is started to drive the rotating worm 220 to rotate. Utilizing the meshing connection between the rotating worm 220 and the rotating worm wheel 221, the rotating worm wheel 221 drives the second rotating ring 216 and the cleaning spiral blade 217 to rotate. The cleaning spiral blade 217 can clean the impurities attached to the surface of the filter screen cylinder 211 and open the second drain pipe 204. Under the action of water flow, impurities can be discharged from the inside of the pump pipe 203, thereby improving the service life of the pump pipe 203. By setting two sets of drive motors 208, the water pressure can be automatically adjusted when the water pressure is insufficient, thereby meeting the water demand. At the same time, the water flow can be filtered and purified, thereby improving the water quality.

[0042] Working principle: Before using this water purification device for secondary water supply tanks, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 11 As shown, firstly, the first rotating motor 104 drives the first rotating disk 105 and the rotating connecting rod 106 to rotate, which in turn drives the first rotating ring 107 and the inner filter cylinder 108 to rotate. The inner filter cylinder 108 can filter larger particulate impurities. At the same time, the inner filter cylinder 108 drives the first connecting bracket 109 and the outer filter cylinder 110 to rotate, which can filter small particulate impurities. The adsorption filter media 124 inside the outer filter cylinder 110 can adsorb and filter water, thereby achieving the effect of purifying water.

[0043] Secondly, since the first outlet pipe 119 of the water storage tank 101 is located at the bottom, the water flows towards the bottom. Therefore, impurities tend to accumulate at the bottom of the inner filter cylinder 108 and the outer filter cylinder 110. Rotation not only prevents impurities from accumulating in one place on the inner and outer filter cylinders 108 and thus affecting their filtration efficiency, but also allows the adsorption filter media 124 to fully adsorb the water flow, improving the adsorption effect. Simultaneously, the fixed connecting rod 114 and the cleaning scraper 115 remain stationary. When the inner filter cylinder 108 rotates, the cleaning scraper... The scraper 115 cleans the impurities adhering to the inner wall of the inner filter cylinder 108, preventing impurities from clogging the inner filter cylinder 108 and affecting its filtration effect. When it is necessary to clean the impurities inside the inner filter cylinder 108, the first drain pipe 103 is opened and the backwash pipe 120 is connected. Under the action of water flow, the impurities inside the inner filter cylinder 108 can be discharged through the first drain pipe 103. At the same time, small particles of impurities on the inner wall of the outer filter cylinder 110 enter the inner filter cylinder 108 and are discharged through the first drain pipe 103, thereby improving the filtration effect of both the inner filter cylinder 108 and the outer filter cylinder 110.

[0044] Finally, the drive motor 208 drives the second rotating disk 212, the connecting outer ring 213, the impeller 214, and the connecting inner ring 215 to rotate. The impeller 214 accelerates the water flow, thereby achieving a pressurization effect. The filter screen 211 performs secondary filtration on the return flow, filtering out impurities such as limescale in the water flow and preventing limescale from adsorbing on the impeller 214, thus affecting the rotation effect of the impeller 214. When it is necessary to clean the filter screen 211, the second rotating motor 219 is started to drive the rotating worm gear 220 to rotate, utilizing the interaction between the rotating worm gear 220 and the rotating worm wheel. The meshing connection between 221 allows the rotating worm gear 221 to drive the second rotating ring 216 and the cleaning spiral blade 217 to rotate. The cleaning spiral blade 217 can clean the impurities attached to the surface of the filter screen cylinder 211 and open the second drain pipe 204. Under the action of water flow, impurities can be discharged from the inside of the pump pipe 203, thereby improving the service life of the pump pipe 203. By setting two sets of drive motors 208, the water pressure can be automatically adjusted when the water pressure is insufficient, thereby meeting the water demand. At the same time, the water flow can be filtered and purified, thereby improving the water quality.
