Description

Technical Field

[0001] The invention relates to the technical field of water treatment, in particular to a water storage tank with filtering and sterilizing functions. Background Art

[0002] As people's requirements for the quality of domestic and industrial water continue to increase, water storage tanks, as key equipment for storing water, are becoming more and more important for their water purification and sterilization functions. Traditional water storage tanks often only have simple storage functions and lack effective treatment mechanisms for water entering the tanks, making it impossible to properly remove large particle impurities, residual chlorine, odors, and various microorganisms that may exist in the water, thereby affecting the safety and quality of water use.

[0003] In the process of applying existing water treatment technology to water storage tanks, although some water storage tanks are equipped with some filtering or sterilization devices, for example, in the filtering link, some equipment cannot effectively slow down the water flow, resulting in concentrated water flow impacting the filtering components, which not only easily damages the filtering structure, but also greatly reduces the filtering effect. Large particles of impurities cannot be fully intercepted, and the filtering components are easily clogged due to the accumulation of impurities, affecting their service life and filtering efficiency.

[0012] Preferably, the adsorption assembly includes a support frame, the top of the support frame is fixedly connected with a flow-blocking component, the bottom of the support frame is fixedly connected with a positioning component, the bottom of the flow-blocking component is movably mounted with an activated carbon cartridge, the bottom of the activated carbon cartridge is in contact with the top of the positioning component, the top of the flow-blocking component is fixedly connected to the bottom of the protective shell, and the adsorption properties of the activated carbon in the activated carbon cartridge are relied upon to remove residual chlorine, odor and some organic pollutants in the water, thereby achieving further purification of the water.

When the baffle block is in contact with the sealing ring, the flow of water can be blocked.

[0017] (III) Beneficial effects

[0018] The present invention provides a water storage tank with filtering and sterilizing function. It has the following beneficial effects:

[0019] (I) The water tank passes through the filter component in the water treatment device. It is initially filtered to remove large particles of impurities; then it flows into the adsorption component, which relies on its adsorption to remove residual chlorine, odor and some organic pollutants in the water; then the water flows to the area below the partition plate in the tank body, during which the drive motor provides power guarantee for the operation of the filter component, and the ultraviolet sterilization lamp destroys the DNA structure of microorganisms in the water by emitting ultraviolet rays to achieve sterilization. Finally, the electrode plate generates strong oxidizing substances through electrolysis reaction to further kill residual microorganisms in the water, jointly ensuring that the water is fully purified and sterilized.

[0020] (ii) The water storage tank passes through a filter assembly. After the water enters the filter assembly, it is first dispersed and slowed down by a slow-flow component so that it flows evenly to an annular filter screen. The annular filter screen intercepts large particles of impurities in the water to achieve preliminary filtration. Subsequently, the filtered water flows through a protective shell into the adsorption assembly.

[0021] (III) The water storage tank is driven by a slow-flow component, and the driving motor drives the arc scraper to rotate through the rotating shell in the slow-flow component. The arc scraper will scrape off the impurities accumulated on the surface during the rotation, so that it flows downward along the gap between the annular filter screen and the annular plate, and finally settles at the bottom of the protective shell. The impurities are discharged through the drain pipe, so that the mesh of the annular filter screen remains unobstructed, thereby ensuring that the annular filter screen continues to play a filtering role and maintains a good filtering efficiency.

[0022] (IV) The water storage tank has a slow-flow component. When the water flowing out of the water inlet pipe hits the conical diverter block, the conical diverter block drives the hollow slide bar to slide into the rotating shell under the impact of the water flow. At this time, the tension spring is stretched, thereby buffering the instantaneous large impact force caused by the impact of the water flow, avoiding the impact force from being directly transmitted to other components and causing structural damage. At the same time, the conical diverter block rotates with the rotating shell through the hollow slide bar. The conical diverter block initially receives the impact of the water flow and uses its own arc-shaped protrusions to change the direction of the water flow, so that it is dispersed and then flows evenly to the annular filter.

[0023] (V) The water storage tank uses an annular plate. The continuous rotation of the annular plate creates a relatively stable and gentle water flow environment, which can prevent the water from forming turbulent water flow or generating a large vortex at the bottom of the protective shell due to excessive impact force. The water flow at the bottom of the protective shell maintains a relatively stable and slow flow state, allowing impurities to be steadily deposited at the bottom and wait to be discharged through the sewage pipe later, effectively ensuring that impurities will not be brought up again during the entire filtration process, maintaining a stable and efficient filtration working order of the filtration component.

[0024] (VI) The water storage tank passes through the adsorption component. After water flows into the adsorption component, it first contacts the flow-blocking component, and then the water flows slowly through the inside of the activated carbon cartridge, relying on the adsorption performance of the activated carbon in the activated carbon cartridge to remove residual chlorine, odor and some organic pollutants in the water, thereby achieving further water purification. The purified water is discharged to the bottom of the tank through the positioning component.

[0025] (VII) The water storage tank has a positioning component. When the activated carbon cartridge needs to be replaced, first remove the bolts fixing the inspection door on the tank body, then turn the knob in the positioning component to make the internal threaded ring rotate in the fixed ring. At this time, under the limiting action of the support frame, the guide tube drives the limiting plate to slide downward, thereby increasing the distance between the limiting plate and the flow blocking component to facilitate the removal of the activated carbon cartridge.

[0026] (VIII) The water storage tank passes through the flow-blocking component, and the activated carbon cylinder moves downward together with the limit plate. During this process, the compression spring gradually releases its elastic force, causing the sliding cylinder to slide downward along the inner side of the sealing ring, and then the connecting rod drives the flow-block to slide downward. When the flow-block contacts the sealing ring, the flow of water can be blocked, preventing water from continuing to flow into the area when the activated carbon cylinder is replaced, preventing water leakage and affecting the replacement operation due to water flow interference, ensuring that the entire replacement process can be carried out safely and orderly.

[0027] (IX) The water storage tank is provided with an adsorption assembly, in which each activated carbon cartridge is relatively independently mounted on a support frame, and each activated carbon cartridge is positioned and constrained by a corresponding positioning component. When a certain activated carbon cartridge needs to be replaced, the corresponding positioning component can be operated, and for other activated carbon cartridges that are not involved in the replacement operation, the corresponding positioning components, flow blocking components and other components in the branch where they are located still maintain their original state, ensuring that the water flow can pass through the corresponding activated carbon cartridge normally for adsorption and purification. Thus, the effect of replacing an activated carbon cartridge without affecting the normal use of other adsorption components is achieved.

[0028] (10) The water storage tank is connected to a sewage pipe. When it is necessary to clean the impurities deposited at the bottom of the protective shell, the activated carbon cartridge can be removed first. At this time, the flow-blocking component can block the flow of water. At this time, the sewage pipe is opened, and then water is injected into the connecting pipe through the water inlet shell, so that the water flows into the rotating shell and finally flows out from the bottom of the annular plate along the rotating shell. At this time, the outflowing water flow can drive the impurities deposited at the bottom of the annular plate to be discharged from the sewage pipe, thereby ensuring the cleanliness of the internal environment of the filter component and helping to maintain the good filtering performance of the filter component.

The water is first filtered to remove large particles of impurities; then it flows into the adsorption component 62, and the residual chlorine, odor and some organic pollutants in the water are removed by its adsorption action; then the water flows to the area below the partition plate 63 in the tank body 1, during which the driving motor 64 provides power guarantee for the operation of the filter component 61, and the ultraviolet sterilization lamp 65 destroys the DNA structure of microorganisms in the water by emitting ultraviolet rays to achieve sterilization. Finally, the electrode plate 7 generates strong oxidizing substances by means of electrolysis reaction, which further kills the residual microorganisms in the water, and together ensures that the water is fully purified and sterilized;

[0043] The filter assembly 61 includes a protective shell 611, the inner side of the protective shell 611 is fixedly connected to an annular filter screen 612, the outer side of the annular filter screen 612 is fixedly connected to a sewage pipe 613, the inner side of the protective shell 611 is rotatably connected to a slow-flow component 614, the outer side of the slow-flow component 614 is fixedly connected to an arc scraper 615, the outer wall of the protective shell 611 is fixedly connected to the top of the inner wall of the tank body 1, the outer wall of the sewage pipe 613 is fixedly connected to the inner wall of the protective shell 611, the outer side of the arc scraper 615 is slidably connected to the inner side of the protective shell 611, and the bottom of the slow-flow component 614 is fixedly connected to the output end of the driving motor 64. After water enters the filter assembly 61, the slow-flow component 614 first disperses and slows the water flow so that it flows evenly to the annular filter screen 612, and the annular filter screen 612 intercepts large particles of impurities in the water to achieve preliminary filtration, and then the filtered water flows through the protective shell 611 into the adsorption assembly 62;

[0044] The slow flow component 614 includes a rotating shell 141, a hollow slide bar 142 is slidably connected to the inner side of the rotating shell 141, a connecting pipe 144 is slidably connected to the inner side of the hollow slide bar 142, a water inlet shell 145 is slidably connected to the top of the connecting pipe 144, a conical diversion block 143 is fixedly connected to the top of the hollow slide bar 142, an annular plate 146 is fixedly connected to the outer wall of the rotating shell 141, a tension spring 147 is fixedly connected to the inner side of the rotating shell 141, and the bottom of the tension spring 147 is connected to the hollow slide bar 145.

In addition to the impurities accumulated on the surface, the impurities flow downward along the gap between the annular filter screen 612 and the annular plate 146, and finally settle at the bottom of the protective shell 611. The impurities are discharged through the drain pipe 613, so that the mesh of the annular filter screen 612 remains unobstructed, thereby ensuring that the annular filter screen 612 continues to play a filtering role and maintains good filtering efficiency. When the water flow flowing out from the water inlet pipe 4 hits the conical diverter block 143, the conical diverter block 143 drives the hollow slide bar 142 to slide into the rotating shell 141 under the impact of the water flow. At this time, the tension spring 147 is stretched by force, thereby buffering the instantaneous large impact force caused by the impact of the water flow, avoiding the impact force being directly transmitted to other components to cause structural damage. At the same time, the conical diverter block 143 rotates with the rotating shell 141 through the hollow slide bar 142. The conical diverter block 143 initially receives the impact of the water flow and uses its own arc-shaped protrusion to change the direction of the water flow, so that it is dispersed, and then it flows evenly to the annular filter screen 612.

[0045] The adsorption assembly 62 includes a support frame 621, the top of the support frame 621 is fixedly connected with a flow blocking component 622, the bottom of the support frame 621 is fixedly connected with a positioning component 624, the bottom of the flow blocking component 622 is movably installed with an activated carbon cartridge 623, the bottom of the activated carbon cartridge 623 is in contact with the top of the positioning component 624, the top of the flow blocking component 622 is fixedly connected to the bottom of the protective shell 611, after water flows into the adsorption assembly 62, it first contacts the flow blocking component 622, and then the water slowly flows through the inside of the activated carbon cartridge 623, relying on the adsorption performance of the activated carbon in the activated carbon cartridge 623 to remove residual chlorine, odor and some organic pollutants in the water, so as to achieve further purification of the water, and the purified water is discharged to the bottom of the tank body 1 through the positioning component 624, in the adsorption assembly 62, each activated carbon cartridge 623 is relatively independently installed on the support frame 621, and each activated carbon cartridge 623 is positioned and constrained by the corresponding positioning component 624. When it is necessary to replace a certain activated carbon cartridge 623, the corresponding positioning component 624 can be operated, and for other activated carbon cartridges 623 that are not involved in the replacement operation, the corresponding positioning components 624, flow blocking components 622 and other components in the branch where they are located still maintain the original state, ensuring that the water flow can normally pass through the corresponding activated carbon cartridge 623 for adsorption and purification. Therefore, the effect of replacing an activated carbon cartridge 623 without affecting the normal use of other adsorption components 62 is achieved.

[0046] The positioning component 624 includes a fixing ring 401, the inner side of the fixing ring 401 is rotatably connected to an internal thread ring 402, the bottom of the internal thread ring 402 is fixedly connected to a knob 403, the inner side of the internal thread ring 402 is threadedly connected to a guide tube 405, the top of the guide tube 405 is fixedly connected to a limit plate 404, the outer side of the fixing ring 401 is fixedly connected to the bottom of the support frame 621, the outer side of the limit plate 404 is slidably connected to the inner side of the support frame 621, and the top of the limit plate 404 is connected to the The bottoms of the activated carbon cartridge 623 are in contact with each other. When the activated carbon cartridge 623 needs to be replaced, first remove the bolts fixing the inspection door 3 on the tank body 1, then rotate the knob 403 in the positioning component 624 to make the internal threaded ring 402 rotate in the fixing ring 401. At this time, under the limiting action of the support frame 621, the guide tube 405 drives the limiting plate 404 to slide downward, thereby increasing the distance between the limiting plate 404 and the baffle component 622, so as to facilitate the removal of the activated carbon cartridge 623.

[0047] The baffle component 622 includes a sealing ring 201, the outer side of the sealing ring 201 is fixedly connected with a compression spring 202, the bottom end of the compression spring 202 is fixedly connected with a sliding cylinder 203, the top of the sliding cylinder 203 is fixedly connected with a connecting rod 204, the top of the connecting rod 204 is fixedly connected with a baffle block 205, the outer side of the sealing ring 201 is fixedly connected to the top of the support frame 621, the outer side of the sliding cylinder 203 is slidably connected to the inner side of the sealing ring 201, the bottom of the baffle block 205 is in contact with the top of the sealing ring 201, and the bottom of the sliding cylinder 203 is in contact with the top of the activated carbon cylinder 623. During this process, the activated carbon cylinder 623 moves downward together with the limit plate 404. During this process, the compression spring 202 gradually releases its elastic force, so that the sliding cylinder 203 slides downward along the inner side of the sealing ring 201, and then the connecting rod 204 drives the flow block 205 to slide downward. When the flow block 205 contacts the sealing ring 201, the flow of water can be blocked, so as to prevent the water from continuing to flow into the area when the activated carbon cylinder 623 is replaced, and to prevent water leakage and the situation that the replacement operation is affected by the interference of water flow, so as to ensure that the entire replacement process can be carried out safely and orderly; in the adsorption assembly 62, each activated carbon cylinder 623 is relatively independently installed on the support frame 621, and each activated carbon cylinder 623 is positioned and constrained by the corresponding positioning component 624. When it is necessary to replace a certain activated carbon cylinder 623, the corresponding positioning component 624 can be operated, and for other activated carbon cylinders 623 that are not involved in the replacement operation, the corresponding positioning components 624, flow blocking components 622 and other components in the branch where they are located still maintain the original state, ensuring that the water flow can pass through the corresponding activated carbon cylinder 623 for adsorption and purification treatment. Thereby, the effect of replacing one activated carbon cartridge 623 without affecting the normal use of other adsorption components 62 is achieved.

[0048] Working principle: The water storage tank is composed of a tank body 1, supporting legs 2, an inspection door 3, a water inlet pipe 4, a drain pipe 5 and a water treatment device 6. The core water treatment process is mainly implemented by the water treatment device 6. The components inside the water treatment device 6 work together to filter, adsorb and sterilize the water entering the tank body 1 from the water inlet pipe 4 in turn. The treated water can be discharged through the drain pipe 5 for use.

[0049] When in use, water enters the tank through the water inlet pipe 4 at the top of the tank body 1, and then enters the filter component 61 in the water treatment device 6. The water is initially filtered to remove large particles of impurities; then it flows into the adsorption component 62, which removes residual chlorine, odor and some organic pollutants in the water by its adsorption action; then the water flows to the area below the partition plate 63 in the tank body 1, during which the drive motor 64 provides power guarantee for the operation of the filter component 61, and the ultraviolet sterilization lamp 65 destroys the DNA structure of microorganisms in the water by emitting ultraviolet rays to achieve sterilization. Finally, the electrode plate 7 generates strong oxidizing substances by means of electrolysis reaction, which further kills the residual microorganisms in the water, and jointly ensures that the water is fully purified and sterilized; among them, the model of the ultraviolet sterilization lamp 65 is Aquafine17491LM, and the model of the electrode plate 7 is Jingyuanjia JYJ-ARC-02.

[0050] After the water enters the filter assembly 61, the water flow is first dispersed and slowed down by the slow-flow component 614 so that it flows evenly to the annular filter 612. The annular filter 612 intercepts large particles of impurities in the water to achieve preliminary filtration. Then the filtered water flows through the protective shell 611 and flows into the adsorption assembly 62.

[0051] During this process, the driving motor 64 drives the arc scraper 615 to rotate through the rotating shell 141 in the slow-flow component 614. The arc scraper 615 will scrape off the impurities accumulated on its surface during the rotation, so that it flows downward along the gap between the annular filter screen 612 and the annular plate 146, and finally settles at the bottom of the protective shell 611. The impurities are discharged through the drain pipe 613, so that the mesh of the annular filter screen 612 remains unobstructed, thereby ensuring that the annular filter screen 612 continues to play a filtering role and maintains good filtering efficiency.

[0052] When the water flowing out from the water inlet pipe 4 hits the conical diverter block 143, the conical diverter block 143 drives the hollow slide bar 142 to slide into the rotating shell 141 under the impact of the water flow. At this time, the tension spring 147 is stretched, thereby buffering the instantaneous large impact force caused by the impact of the water flow, avoiding the impact force from being directly transmitted to other components to cause structural damage. At the same time, the conical diverter block 143 rotates with the rotating shell 141 through the hollow slide bar 142. The conical diverter block 143 initially receives the impact of the water flow and uses its own arc-shaped protrusions to change the direction of the water flow, so that it is dispersed, and then evenly flows to the annular filter screen 612;

[0053] The relatively stable and gentle water flow environment created by the continuous rotation of the annular plate 146 can prevent the formation of turbulent water flow or large vortex at the bottom of the protective shell 611 due to excessive impact force, so that the water flow at the bottom of the protective shell 611 maintains a relatively stable and slow flow state, allowing impurities to be steadily deposited at the bottom and wait to be discharged through the sewage pipe 613 later, effectively ensuring that impurities will not be brought up again during the entire filtration process, maintaining a stable and efficient filtration working order of the filter component 61.

[0054] After water flows into the adsorption assembly 62, it first contacts the flow-blocking component 622, and then the water flows slowly through the interior of the activated carbon cartridge 623, relying on the adsorption performance of the activated carbon in the activated carbon cartridge 623 to remove residual chlorine, odor and some organic pollutants in the water, thereby achieving further purification of the water. The purified water is discharged to the bottom of the tank body 1 through the positioning component 624.

[0055] When the activated carbon cartridge 623 needs to be replaced, first remove the bolts fixing the inspection door 3 on the tank body 1, then rotate the knob 403 in the positioning component 624 to make the internal thread ring 402 rotate in the fixing ring 401. At this time, under the limiting effect of the support frame 621, the guide tube 405 drives the limiting plate 404 to slide downward, thereby increasing the distance between the limiting plate 404 and the flow blocking component 622, so as to facilitate the removal of the activated carbon cartridge 623.

[0056] During this process, the activated carbon cartridge 623 moves downward together with the limit plate 404. During this process, the compression spring 202 gradually releases its elastic force, causing the sliding cylinder 203 to slide downward along the inner side of the sealing ring 201, and then the connecting rod 204 drives the baffle block 205 to slide downward. When the baffle block 205 contacts the sealing ring 201, it can block the flow of water, preventing water from continuing to flow into the area when replacing the activated carbon cartridge 623, preventing water leakage and affecting the replacement operation due to water flow interference, ensuring that the entire replacement process can be carried out safely and orderly.

[0057] In the adsorption assembly 62, each activated carbon cartridge 623 is relatively independently installed on the support frame 621, and each activated carbon cartridge 623 is positioned and constrained by a corresponding positioning component 624. When a certain activated carbon cartridge 623 needs to be replaced, the corresponding positioning component 624 can be operated, and for other activated carbon cartridges 623 that are not involved in the replacement operation, the corresponding positioning components 624, flow blocking components 622 and other components in the branch where they are located still maintain the original state, ensuring that the water flow can pass through the corresponding activated carbon cartridge 623 normally for adsorption and purification. Thereby achieving the effect of not affecting the normal use of other adsorption assemblies 62 when replacing an activated carbon cartridge 623.

[0058] When it is necessary to clean the impurities deposited at the bottom of the protective shell 611, the activated carbon cartridge 623 can be removed first. At this time, the flow-blocking component 622 can block the flow of water. At this time, the drain pipe 613 is opened, and then water is injected into the connecting pipe 144 through the water inlet shell 145, so that the water flows into the rotating shell 141 and finally flows out from the bottom of the annular plate 146 along the rotating shell 141. At this time, the outflowing water flow can drive the impurities deposited at the bottom of the annular plate 146 to be discharged from the drain pipe 613, thereby ensuring the cleanliness of the internal environment of the filter component 61 and helping to maintain the good filtering performance of the filter component 61.
