Description

Technical Field

[0001] This invention relates to the field of water purification equipment technology; specifically, this invention relates to a micro-nano bubble small molecular cluster water purification device. Background Technology

[0002] Micro-nano bubble water purification devices are a highly efficient water treatment technology that enhances water purification by generating extremely fine bubbles, making them particularly suitable for wastewater treatment, water remediation, and aquaculture. Currently, mainstream micro-nano bubble water purification devices mainly consist of a booster pump, a dissolved air tank, and a bubble generator. During operation, the booster pump simultaneously delivers water and gas into the dissolved air tank for pressurization, followed by instantaneous depressurization by the bubble generator to produce micro-nano bubbles. To improve water purification efficiency and extend the device's lifespan, a pre-filter is needed at the inlet to filter large particulate impurities. This necessitates cleaning the device after a period of use. Current mainstream cleaning methods involve disassembling the device, cleaning each component individually, and then reassembling. This is not only time-consuming and labor-intensive, but also requires sufficient expertise in the product for proper operation.

Detailed Implementation

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below. 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.

[0020] like Figure 1 , Figure 6 and Figure 7 As shown, this embodiment provides a micro-nano bubble water molecule cluster water purification device, including a main shell 1, a dissolved air chamber 5, a water inlet chamber, a filter cartridge 9, a valve body, and a bottom cover 11.

[0021] An ozone generator 2 and a self-priming booster pump 3 are installed inside the main body shell 1. The gas supply pipe 4 of the ozone generator 2 is connected to the booster pump 3. During the process of the booster pump 3 delivering water, the ozone generator 2 introduces ozone into the water, so that the ozone mixes with the water.

[0022] The dissolved air chamber 5 is connected to the top of the main body shell 1, and the dissolved air chamber 5 and the main body shell 1 are detachably connected. The water outlet of the booster pump 3 is connected to the bottom of the dissolved air chamber 5, and the ozone and water mixture discharged by the booster pump 3 enters the dissolved air chamber 5.

[0023] The outlet of the dissolved air chamber 5 is connected in sequence to a bubble generator 6 and a water outlet pipe 7. After the ozone-water mixture enters the dissolved air chamber 5, it is pressurized, allowing the ozone to dissolve efficiently in the water. When the ozone-water mixture passes through the bubble generator 6, the fluid velocity increases due to instantaneous pressure relief, and the dissolved gas is released, forming a large number of micro- and nano-bubbles, which are finally discharged from the water outlet pipe 7.

[0024] The water inlet chamber is connected to the bottom of the main body shell 1, and a water inlet pipe 8 is connected to the outside of the water inlet chamber. Optionally, the water inlet pipe 8 is a flexible hose, and the water inlet end shell of the water inlet pipe 8 is equipped with a quick connector for connecting to a tap. External water is drawn in and pressurized by the booster pump 3 through the water inlet pipe 8 and the water inlet chamber.

[0025] The inlet is located at the center of the water inlet chamber, and the water inlet chamber has a first water inlet 10 at the center of the top of the filter cartridge 9. Water enters the center of the filter cartridge 9 from the outside of the filter cartridge 9, and then the water is drawn away by the booster pump 3 through the first water inlet 10. During this process, the filter cartridge 9 can filter and pre-treat the water.

[0026] The valve body is located between the first water inlet 10 and the inlet end of the booster pump 3. The water in the center of the filter cartridge 9 enters the booster pump 3 through the first water inlet 10 and the valve body to form the first water path. When the water purification device is running normally, the water flows in the first water path.

[0027] The water in the inlet chamber bypasses the filter cartridge 9 and directly enters the booster pump 3 through the valve body to form a second water path. The valve body can switch between the first and second water paths. The bottom cover 11 is attached to the bottom of the inlet chamber to seal the bottom of the inlet chamber.

[0028] After the bottom cover 11 is removed, the bottom end of the dissolved air chamber 5 can be connected to the bottom end of the water inlet chamber, the water outlet pipe 7 can be connected to the water outlet of the booster pump 3, and a drain outlet 12 that can be opened and closed is provided on one side of the dissolved air chamber 5.

[0029] The water purification equipment is started normally, and a portion of the micro-nano bubble water is collected in another container. Then, the bottom cover 11 is removed, the bottom of the container cavity is connected to the bottom of the inlet cavity, and the outlet pipe 7 is connected to the outlet of the booster pump 3. The drain port 12 is opened, and the water purification equipment is adjusted to the second water path through the valve body. The water purification device is then started again. The micro-nano bubble water collected in the container enters the dissolved air chamber 5 and then flows into the inlet cavity, and then is discharged from the drain port 12. During the water circulation process, the filter cartridge 9, the inlet cavity, and the dissolved air chamber 5 are cleaned.

[0030] like Figure 1 As shown, the micro-nano bubble small molecule cluster water purification device of this embodiment also includes a central tube 13, a spiral plate 14, a protrusion 15, and a sealing plate 17.

[0031] A central tube 13 is positioned at the center of the dissolved air chamber 5, with its bottom end fixed to the top of the main body shell 1. A spiral plate 14 is positioned inside the dissolved air chamber 5 and is slidably fitted around the central tube 13, with its bottom end supported on the top of the main body shell 1. Water entering the dissolved air chamber 5 moves along the spiral plate 14, causing the water flow to rotate and prolonging its residence time within the dissolved air chamber 5. The obstruction effect of the spiral plate 14 on the water flow assists the booster pump 3 in improving the pressurization effect, allowing ozone to dissolve more effectively in the water.

[0032] A protrusion 15 is located at the top of the dissolved air chamber 5, and a grid hole 16 is located within the protrusion 15 at the top of the side of the central tube 13. A sealing plate 17 is fixedly installed on the top of the spiral plate 14, and the lower surface of the sealing plate 17 is spirally fitted with the top of the spiral plate 14, which can close the opening of the protrusion 15 facing the main cavity and seal the grid hole 16 within the protrusion 15. During normal operation of the water purification equipment, the grid hole 16 is sealed within the protrusion 15 by the sealing plate 17, so that the water flowing through the dissolved air chamber 5 will not enter the inner cavity of the central tube 13 through the grid hole 16.

[0033] The outlet of the dissolved air chamber 5 is located between the two spirals at the top of the spiral plate 14, which improves the flow of water. The outer and inner diameters of the filter cartridge 9 are adapted to the outer and inner diameters of the central tube 13, respectively. The spiral plate 14 can be inserted into the water inlet chamber from the bottom end, so that the sealing plate 17 and the protrusion 15 are separated from the opening facing the main body shell 1. In the rinsing state, after the water flows into the dissolved air chamber 5 from the blow pipe, it will pass through the gap between the sealing plate 17 and the protrusion 15 and enter the protrusion 15. Then, it will enter the interior of the central tube 13 through the grid hole 16, so that the water will enter the interior of the filter cartridge 9. Then, it will be discharged from the inside to the water inlet chamber through the filter cartridge 9. Finally, the water flows down along the spiral plate 14 and is discharged through the drain outlet 12.

[0034] The water flow can backwash the filter cartridge 9 from the inside out, improving the cleaning effect of the filter cartridge 9. During the backwashing process, the sealing plate 17 can be located between the drain port 12 and the outlet, dividing the dissolved air chamber 5 into upper and lower parts, so that the water flow follows the path of the lower part of the dissolved air chamber 5 - protrusion 15 - grid hole 16 - central pipe 13 - inside of the filter cartridge 9 - upper part of the dissolved air chamber 5 - drain port 12.

[0035] The central tube 13 contains a protective tube 43, and the protective tube 43 contains an ultraviolet lamp 44. Both the protective tube 43 and the ultraviolet lamp 44 are fixed to the top center of the main body shell 1. When the dissolved air chamber 5 is removed from the top of the main body shell 1, the central tube 13 is pulled out from the outside of the protective tube 43. Both the central tube 13 and the protective tube 43 are made of quartz glass tubes. When combined with the ultraviolet lamp 44, the water purification device forms an advanced oxidation process of ultraviolet light + ozone + micro-nano bubbles, and its water purification effect is far superior to using ozone or micro-nano bubbles alone.

[0036] like Figure 1As shown, the micro / nano bubble small molecule cluster water purification device of this embodiment also includes a first spring 18 and a cover 19. The first spring 18 is disposed between the top of the cover plate 17 and the inner top wall of the protrusion 15, and is used to provide elastic force for the spiral plate 14 to be inserted into the water inlet cavity. When the dissolved air cavity 5 is connected to the top of the main body shell 1, the bottom end of the spiral plate 14 is pressed upward by the top of the main body shell 1, so that the first spring 18 is compressed in the protrusion 15. After the dissolved air cavity 5 is removed from the top of the main body cavity, the elastic force of the first spring 18 causes the spiral plate 14 to automatically move away from the protrusion 15, so that a gap is formed between the cover plate 17 and the protrusion 15, so that after the dissolved air cavity 5 is connected to the bottom of the water inlet cavity, the water flow can enter the protrusion 15 through the gap.

[0037] The sleeve 19 is fixedly installed on the top of the sealing plate 17. The first spring 18 is located inside the sleeve 19, and the central tube 13 is located inside the first spring 18. The outer diameter of the sleeve 19 is adapted to the inner diameter of the protrusion 15. By setting the sleeve 19, water can only enter the protrusion 15 from the lower part of the dissolved air chamber 5 in the rinsing state when the sleeve 19 is pulled out from the protrusion 15.

[0038] When the first spring 18 is in a free state, the outlet of the dissolved air chamber 5 is located between the sealing plate 17 and the inner top wall of the dissolved air chamber 5. After the dissolved air chamber 5 is connected to the bottom of the inlet chamber, the water flow entering the lower part of the dissolved air chamber 5 is located between the sealing plate 17 and the inner wall of the lower part of the dissolved air chamber 5 near the protrusion 15. The booster pump 3 continuously sends water in, and the water flow uses pressure to push the sealing plate 17 upward. The sealing plate 17 drives the spiral plate 14 to move upward to the highest position, the first spring 18 is stretched, and the cover 19 is pulled out from the protrusion 15, finally reaching a dynamic balance state and realizing backwashing.

[0039] like Figure 1 As shown, when the spiral plate 14 is inserted to the highest position of the water inlet chamber, the end of the spiral plate 14 away from the protrusion 15 contacts the inner top wall of the water inlet chamber, and the drain outlet 12 is located between the two spirals at the top of the spiral plate 14. The external thread of the drain outlet 12 is fitted with a sealing cap 20.

[0040] like Figure 1 , Figure 4 , Figure 6 and Figure 7 As shown, the valve body in this embodiment includes a valve shell 21, a valve ball 22, and a second inlet 23.

[0041] The top and bottom of the valve housing 21 are connected to the inlet of the booster pump 3 and the first water inlet 10, respectively. A valve ball 22 is rotatably mounted inside the valve housing 21, and a channel is provided in the center of the valve ball 22. The second water inlet 23 is located on the side of the valve housing 21. When the water purification device is in the first water path state, the channel and the first water inlet 10 are connected, and the water flows through the first water inlet 10, the channel, and the valve housing 21 before entering the booster pump 3. When the water purification device is in the second water path state, the water flows through the second water inlet 23, the channel, and the valve housing 21 before entering the booster pump 3.

[0042] The water inlet chamber in this embodiment includes a lower cavity 24, an upper cavity 25, an outer cavity 26, a first water guide hole 27, and a second water guide hole 28.

[0043] The first inlet 10 is located at the top center of the lower cavity 24. The filter cartridge 9 is located inside the lower cavity 24, and the bottom end of the lower cavity 24 is open. The bottom cover 11 is installed at the bottom end of the lower cavity 24, and the dissolved air chamber 5 can be connected to the bottom end of the lower cavity 24. The upper cavity 25 is located at the top of the lower cavity 24, and the valve body is located inside the upper cavity 25. The main body shell 1 is connected to the top of the upper cavity 25. The outer cavity 26 is annular and surrounds the outer circumference of the lower cavity 24 and the upper cavity 25.

[0044] The first water guide hole 27 is located on the side of the upper cavity 25, connecting the upper cavity 25 to the outer cavity 26. The second water guide hole 28 is located at the bottom of the upper cavity 25, connecting the lower cavity 24 to the upper cavity 25. The water inlet pipe 8 is connected to the outer cavity 26, and a sealing component capable of blocking the second water guide hole 28 is provided inside the lower cavity 24.

[0045] When the water purification device is in the first water path state, the second water guide hole 28 is open. Water flows through the first water guide hole 27 from the outer cavity 26 into the upper cavity 25, and then through the second water guide hole 28 from the upper cavity 25 into the lower cavity 24. Finally, it enters the interior of the filter cartridge 9 from the outside and is filtered and pretreated.

[0046] When the water purification device is in the second water circuit state, the sealing component blocks the second water guide hole 28, and the water flows through the first water guide hole 27 from the outer cavity 26 into the upper cavity 25, and then through the second water outlet 23 through the valve body into the booster pump 3.

[0047] like Figure 4 and Figure 5 Optionally, the sealing assembly includes a plug 29, a ring plate 30, and two lifting plates 31.

[0048] The plug 29 seals the second water guide hole 28 by rubbing it upwards into the second water guide hole 28. An annular plate 30 is fixedly installed at the bottom of the plug 29, and the inner diameter of the annular plate 30 is larger than the outer diameter of the filter cartridge 9. When the second water guide hole 28 is open, the water in the upper cavity 25 falls through the second water guide hole 28, and the water flow can completely cover the filter cartridge 9 through the gap between the inner surface of the annular plate 30 and the surface of the filter cartridge 9, improving the water filtration and pretreatment effect.

[0049] Two lifting plates 31 are fixedly installed on both sides of the ring plate 30, and the lifting plates 31 are slidably installed in the water inlet chamber. When the top of the dissolved air chamber 5 is connected to the bottom of the water inlet chamber, the upper lifting plate 31 is used to block the second water guide hole 28 by the plug 29, which simplifies the operation.

[0050] like Figure 1 and Figure 2 As shown, the top end of the lifting plate 31 penetrates the top of the lower cavity 24 and extends into the upper cavity 25. In this embodiment, the valve body also includes a rotating shaft 32, a gear 33, a rack 34, and a second spring 35.

[0051] The rotating shaft 32 is fixedly installed on both sides of the valve ball 22, and the outer end of the rotating shaft 32 passes through the valve housing 21; the gear 33 is fixedly installed on the outer end of the rotating shaft 32; the rack 34 is fixedly installed on the top of the lifting plate 31, and the rack 34 meshes with the gear 33; the second spring 35 is installed on the top of the rack 34 to provide downward pressure to the rack 34; when the plug 29 blocks the second water guide hole 28, the rack 34 drives the rotating shaft 32 to rotate 90° through the gear 33, so that the water purification device switches from the first water path to the second water path.

[0052] During the process of connecting the dissolved air chamber 5 to the bottom of the water inlet chamber, the water purification device can automatically switch from the first water path state to the second water path state. After the dissolved air chamber 5 is removed from the bottom of the water inlet chamber, the second spring 35 causes the water purification device to automatically switch from the second water path state to the first water path state, thereby simplifying the operation.

[0053] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the top surface of the main shell 1 is in a spiral fit with the bottom of the spiral plate 14; the outer side of the main shell 1 is provided with an upper threaded sleeve 36, the bottom of the outer side of the dissolved air chamber 5 is provided with an external thread 37, and the bottom of the water inlet chamber is provided with a lower threaded sleeve 38. The external thread 37 can be threadedly engaged with the upper threaded sleeve 36 and the lower threaded sleeve 38, and the base is threadedly installed in the lower threaded sleeve 38.

[0054] The upper threaded sleeve 36, through its thread engagement with the external thread 37, enables the dissolved air chamber 5 to be stably connected to the top of the main shell 1, and the lower threaded sleeve 38, through its thread engagement with the external thread 37, enables the dissolved air chamber 5 to be stably connected to the bottom of the water inlet chamber.

[0055] Optionally, guide strips 39 are provided on both sides of the inner wall of the dissolved air chamber 5, and guide grooves 40 adapted to the guide strips 39 are provided on the outer circumferential surface of the spiral plate 14 and the top of the main shell 1. In this embodiment, when the dissolved air chamber 5 is connected to the bottom of the water inlet chamber, the top of the guide strip 39 pushes against the bottom of the lifting plate 31, and the lifting plate 31 is configured to have the same cross-sectional size as the guide strip 39. During the upward displacement of the spiral plate 14 in the water inlet chamber, the guide grooves 40 on the spiral plate 14 can fit onto the lifting plate 31.

[0056] Optionally, a microporous aeration head 41 is threadedly installed at the outlet end of the water outlet pipe 7, and a third water guide hole 42 is provided on the top side of the main body shell 1 corresponding to the bottom end of the spiral plate 14.
