Description

Technical Field

[0001] This invention relates to the field of multi-media filtration equipment technology, specifically to a multi-media high-efficiency filtration equipment for natural mineral water. Background Technology

[0002] In recent years, multi-media filtration equipment technology has been significantly improved, mainly in terms of the diversification of filter media and the intelligence of system design. Traditional filtration equipment usually uses a single media, such as sand or activated carbon. With the advancement of technology, composite multi-media filtration systems have gradually emerged, combining the advantages of different materials to achieve more efficient pollutant removal. The new filter media not only perform well in filtration but also have a longer service life, promoting the widespread application of multi-media filtration equipment in industrial and domestic water treatment fields.

[0003] Multi-media filtration equipment still has some significant problems during use. When cleaning the filter media, the backwash water flow carries away fine particles in the media, which leads to a decrease in the filtration performance of the filter media. As fine particles are lost, the effective filtration capacity of the media layer is affected, gradually reducing its efficiency in removing pollutants from the water. After the layered structure of the filter media is damaged, the replacement cycle will also be shortened, increasing operating costs and maintenance frequency. Frequent media replacement not only brings economic burden to enterprises, but also affects the continuity and stability of water treatment, failing to meet actual needs.

[0004] The inventors of this application discovered in their research that the core defect of the aforementioned prior art is that during the backwashing process, fine particles are lost from the multi-media filtration equipment, leading to a decrease in filtration performance, affecting the efficiency of pollutant removal, shortening the media replacement cycle, and increasing operating costs. Summary of the Invention

[0005] This invention provides a multi-media high-efficiency filtration device for natural mineral water, which solves the problem that fine particles are lost during the backwashing process of multi-media filtration devices, resulting in decreased filtration performance, reduced pollutant removal efficiency, shortened media replacement cycle, and increased operating costs. It increases the proportion of fine particles in the media layer, thereby repairing the filter media layer.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a multi-media high-efficiency filtration device for natural mineral water, including a pressure tank, an inlet pipe inserted into the top of the pressure tank, a outlet pipe inserted into the bottom of the pressure tank, and a valve mechanism installed at one end of the outlet pipe and the inlet pipe, the valve mechanism being used to control the flow direction of the water; A control mechanism is installed at the bottom of the pressure tank near the drain pipe.

[0009] By adopting the above technical solution, multiple layers of filter media are set inside the pressure tank, including an activated carbon layer, a fine quartz sand layer, and a coarse quartz sand layer. Wastewater enters the pressure tank through the filter port and the water inlet pipe. After being filtered by the multiple layers of filter media, the filtered water is discharged from the drain pipe and the first outlet, leaving flocculent impurities and colloidal impurities in the media layer, thus achieving the effect of filtering mineral water.

[0010] In a preferred embodiment, the water distributor mechanism further includes a plurality of first mounting cylinders disposed on the surface of the water distribution plate. A mounting frame is fixedly connected to the bottom of the inner wall of the pressure tank. A fixed cylinder is fixedly connected to the middle position of the mounting frame. The two ends of the fixed cylinder are rotatably connected to the water distribution plate. A sealing cylinder is disposed inside the fixed cylinder. A connecting cylinder is fixedly connected to the top of the reset pipe and the start pipe respectively. A rotating disk is rotatably connected to one end of the connecting cylinder. A connecting pipe is inserted into one side of the rotating disk.

[0011] The rotating disk and the connecting pipe are fixedly connected to the water distribution disk. One end of the connecting pipe is equipped with a water spray strip, and the bottom of the water spray strip is equipped with multiple nozzles. The inner walls on both sides of the pressure tank are respectively equipped with protrusions, one protrusion is located at the bottom of the edge of the water distribution disk, and the other protrusion is located at the top of the edge of the water distribution disk.

[0012] The rotating mechanism includes a rotating column rotatably connected to the top of the branch pipe. The rotating column has multiple oblique holes inside, which communicate with the branch pipe. The rotating column is rotatably connected to the mounting frame. A rotating shaft is fixedly connected to the top of the rotating column. Two grinding shells are fixedly connected to the top of the mounting frame. Multiple second mounting cylinders are inserted into the four edges of the grinding shells. A grinding cavity is provided on the top of the inner wall of the grinding shell.

[0013] The first and second mounting cylinders are slidably connected to guide rods inside. The first and second mounting cylinders are provided with multiple water flow holes near the edge of the guide rods inside. One end of the first and second mounting cylinders is provided with a shroud. One end of the guide rod inside the first mounting cylinder is provided with a filter plate, and one end of the guide rod inside the second mounting cylinder is provided with a rubber sheet.

[0014] The grinding mechanism includes two grinding discs fixedly connected to the top of the rotating shaft. The grinding discs rotate inside the grinding shell. The top of the grinding shell is provided with multiple feed holes, and the bottom of the inner wall of the grinding shell is provided with a connecting cavity and multiple flow grooves.

[0015] The connecting cavity is connected to the top of the water spray pipe and connects to multiple flow channels.

[0016] The bottom surface of the pressure tank is fixedly connected to multiple support legs, and one end of the drain pipe is located at the bottom of the water washing port, with a drain outlet and a water inlet respectively.

[0017] This invention provides a multi-media high-efficiency filtration device for natural mineral water. It has the following beneficial effects: 1. This invention uses a rotating shaft to drive two grinding discs to rotate. Activated carbon and quartz sand enter the interior of the grinding shell through the feed hole by gravity. The grinding discs and the grinding shell rotate relative to each other to grind the activated carbon and quartz sand, so that the large particles of activated carbon and quartz sand are ground into fine particles. High-pressure water carries away the ground fine particles. The fine particles are squeezed by the water flow and sprayed out from one end of the second mounting cylinder, which increases the proportion of fine particles in the media layer and achieves the effect of repairing the filter media layer.

[0018] 2. This invention uses multiple second mounting cylinders to spray water, causing the filter media layer to expand and loosen. This allows high-pressure water to flow through the starting pipe into the interior of the connecting cylinder. The high-pressure water then enters the connecting cylinder on one side of the starting pipe and is sprayed out through multiple nozzles. The reaction force of the water flow causes the water distribution plate to rotate counterclockwise, stopping the water distribution plate at the edge of the lower maintenance port. This opens the sealing door outside the lower maintenance port, allowing the media layer inside the pressure tank to slide out from the lower maintenance port, thus achieving the effect of quickly replacing the media layer inside the pressure tank.

[0019] 3. This invention uses water sprayed from multiple second mounting cylinders to clean the upper surface of the water distribution plate, thoroughly cleaning the water distribution plate. The water flow washes away impurities from the surfaces of multiple first mounting cylinders, reducing the likelihood of impurities clogging the first mounting cylinders and extending the replacement cycle of the first mounting cylinders.

[0020] 4. This invention allows for the inspection and cleaning of the bottom space of the water distribution plate through the middle maintenance port and the second lower maintenance port. At the same time, excess clean water is filtered through the filter plates inside multiple first installation cylinders, and the clean water flows into the bottom of the water distribution plate, allowing the impurities at the bottom of the pressure tank to flow back and be discharged through the drain port, thus achieving the effect of thoroughly removing impurities from inside the pressure tank.

After being filtered by the multi-layer filter medium, the filtered water is discharged from the drain pipe 4 and the first water outlet 6, leaving flocculent impurities and colloidal impurities in the medium layer, thus achieving the effect of filtering mineral water.

[0028] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 9 and Figure 10 In a preferred embodiment, the water distributor mechanism further includes a plurality of first mounting cylinders 29 disposed on the surface of the water distribution plate 15. A mounting frame is fixedly connected to the bottom of the inner wall of the pressure tank 1. A fixing cylinder 24 is fixedly connected to the middle position of the mounting frame. The two ends of the fixing cylinder 24 are rotatably connected to the water distribution plate 15. A sealing cylinder 25 is disposed inside the fixing cylinder 24. A connecting cylinder 26 is fixedly connected to the top of the reset pipe 21 and the start pipe 22 respectively. A rotating disk 27 is rotatably connected to one end of the connecting cylinder 26.

[0029] The rotating disk 27 and the connecting pipe 17 are fixedly connected to the water distribution disk 15. One end of the connecting pipe 17 is provided with a water spray strip 16. The bottom of the water spray strip 16 is provided with multiple nozzles 43. The inner walls on both sides of the pressure tank 1 are respectively provided with protrusions 42. One protrusion 42 is located at the bottom of the edge of the water distribution disk 15, and the other protrusion 42 is located at the top of the edge of the water distribution disk 15.

[0030] The rotating mechanism includes a rotating column 14 rotatably connected to the top of the branch pipe 23. The rotating column 14 has multiple inclined holes inside, which communicate with the branch pipe 23. The rotating column 14 is rotatably connected to the mounting frame. A rotating shaft 13 is fixedly connected to the top of the rotating column 14. Two grinding shells 12 are fixedly connected to the top of the mounting frame. Multiple second mounting cylinders are inserted into the four edges of the grinding shells 12. A grinding cavity 35 is provided on the top of the inner wall of the grinding shell 12.

[0031] The first mounting cylinder 29 and the second mounting cylinder are respectively slidably connected to guide rods 28. The first mounting cylinder 29 and the second mounting cylinder are respectively provided with multiple water flow holes 30 near the edge of the guide rods 28. The first mounting cylinder 29 and the second mounting cylinder are provided with a shroud 31 at one end. The guide rod 28 inside the first mounting cylinder 29 is provided with a filter plate 32 at one end. The guide rod 28 inside the second mounting cylinder is provided with a rubber sheet 33 at one end.

[0032] The grinding mechanism includes two grinding discs 38 fixedly connected to the top of the rotating shaft 13. The grinding discs 38 rotate inside the grinding shell 12. The top of the grinding shell 12 is provided with multiple feed holes 34, and the bottom of the inner wall of the grinding shell 12 is provided with a connecting cavity 36 and multiple flow grooves 37.

[0033] The connecting cavity 36 is connected to the top of the water spray pipe 18. The connecting cavity 36 is connected to multiple flow channels 37. Multiple feed channels 39 are provided on the upper surface of the grinding disc 38. A first material accumulation hole 40 and two second material accumulation holes 41 are respectively provided at the bottom of the feed channels 39.

[0034] Multiple support legs 2 are fixedly connected to the bottom surface of the pressure tank 1, and a drain outlet 5 and a water inlet 7 are respectively provided at one end of the drain pipe 4 at the bottom of the water washing port 8.

[0035] In this embodiment, high-pressure clean water enters the bottom of the pressure tank 1 through the water washing port 8. The water pressure squeezes the bottom of the filter plate 32, causing the guide rod 28 to slide upward, so that the clean water enters the medium layer above the water distribution plate 15 from the bottom of the water distribution plate 15, and washes the medium layer, thereby cleaning out the flocculent impurities and colloidal impurities in the medium layer.

[0036] Simultaneously, high-pressure clean water is injected into the interior of the rotating column 14 through the water inlet pipe 19 and the branch pipe 23, causing the high-pressure water to spray out through the inclined hole. The reaction force of the water flow drives the rotating column 14 and the rotating shaft 13 to rotate. The rotating shaft 13 drives the two grinding discs 38 to rotate. As the high-pressure water flows through the media layer, the activated carbon and quartz sand in the media layer expand and flow. The activated carbon and quartz sand enter the interior of the grinding shell 12 through the feed hole 34 by gravity, and then fall into the interior of the feed trough 39.

[0037] Furthermore, activated carbon and quartz sand slide downwards along the second material feeding hole 41, and are ground by the relative rotation of the grinding disc 38 and the grinding shell 12, so that large particles of activated carbon and quartz sand are ground into fine particles. High-pressure clean water is sprayed out from the bottom of the connecting cavity 36 through the water inlet pipe 19 and the water spray pipe 18. The high-pressure clean water carries away the ground fine particles. The fine particles are squeezed by the water flow and squeezed by the rubber sheet 33 and sprayed out from one end of the second mounting cylinder, increasing the proportion of fine particles in the media layer. This ensures that the content of fine particles in the filter media layer is not affected by water washing, and achieves the effect of repairing the filter media layer.

[0038] At the same time, the external high-pressure water flow squeezes the rubber sheet 33, thereby blocking the water flow hole 30 inside the second mounting cylinder, preventing the high-pressure water flow from entering the interior of the grinding shell 12 from the outside of the rubber sheet 33, thus improving the grinding efficiency of the grinding disc 38.

[0039] In this embodiment, after prolonged use, the filter media needs to be replaced. Water is sprayed through multiple second mounting cylinders to expand and loosen the filter media layer. At the same time, the ball valve on the start pipe 22 is opened, allowing high-pressure water to flow through the start pipe 22 into the interior of the connecting cylinder 26. The high-pressure water then enters the interior of the connecting cylinder 26 on one side of the start pipe 22. The water flows through the connecting cylinder 26 and the connecting pipe 17 into the spray strip 16 at the bottom edge of one end of the water distribution plate 15. The water is sprayed out through multiple nozzles 43. The reaction force of the water flow causes the water distribution plate 15 to rotate counterclockwise, causing the water distribution plate 15 to stop at the edge of the lower maintenance port 3. The sealing door outside the lower maintenance port 3 is opened, allowing the media layer inside the pressure tank 1 to slide out from the lower maintenance port 3, thus achieving the effect of quickly replacing the media layer inside the pressure tank 1.

[0040] At the same time, the water sprayed from multiple second mounting cylinders cleans the upper surface of the water distribution plate 15, achieving the effect of thoroughly cleaning the water distribution plate 15.

[0041] At the same time, the water flow washes away impurities from the surface of multiple first mounting cylinders 29, reducing the likelihood of impurities clogging the first mounting cylinders 29 and extending the replacement cycle of the first mounting cylinders 29.

[0042] In this embodiment, the bottom space of the water distribution plate 15 is inspected and cleaned through the middle maintenance port and the second lower maintenance port 3. At the same time, excess clean water is filtered through the filter plates 32 inside the multiple first mounting cylinders 29. The clean water flows into the bottom of the water distribution plate 15, and the impurities at the bottom of the pressure tank 1 are flushed away and discharged through the drain port 5, which achieves the effect of thoroughly removing impurities from the inside of the pressure tank 1.

[0043] After cleaning, high-pressure water is injected into the spray strip 16 at the bottom edge of the other end of the water distribution plate 15 through the branch pipe 23. The reaction force of the high-pressure water flow drives the water distribution plate 15 to rotate clockwise, so that the water distribution plate 15 returns to a horizontal position. The new medium layer is then placed on the upper surface of the water distribution plate 15 through the upper maintenance port and the middle maintenance port.

[0044] Multiple pressure tanks 1 can be used simultaneously, and the high-pressure water flow can be shared with the adjacent pressure tanks 1 through the water inlet 7, thus achieving the effect of multiple pressure tanks 1 working at the same time.

[0045] Working process: During use, multiple layers of filter media are installed inside the pressure tank 1, including an activated carbon layer, a fine quartz sand layer, and a coarse quartz sand layer. Wastewater enters the pressure tank 1 through the filter port 9 and the water inlet pipe 11. After being filtered by the multiple layers of filter media, it passes through the filter plates 32 inside multiple first mounting cylinders 29. The filtered water is discharged from the drain pipe 4 and the first outlet 6, leaving flocculent and colloidal impurities in the media layer, thus achieving the effect of filtering mineral water. After prolonged use, the media layer needs to be cleaned. High-pressure clean water enters the bottom of the pressure tank 1 through the water washing port 8. The water pressure squeezes the bottom of the filter plates 32, causing the guide rod 28 to slide upward, thereby allowing clean water to enter the media layer above the water distribution plate 15 from the bottom of the water distribution plate 15 to rinse the media layer. This process removes flocculent and colloidal impurities from the media layer. Simultaneously, high-pressure water is injected into the rotating column 14 through the inlet pipe 19 and branch pipe 23, causing the high-pressure water to spray out through the oblique holes. The reaction force of the water flow drives the rotating column 14 and rotating shaft 13 to rotate, which in turn drives the two grinding discs 38 to rotate. As the high-pressure water washes the media layer, the activated carbon and quartz sand in the media layer expand and flow. The activated carbon and quartz sand enter the grinding shell 12 through the feed hole 34 by gravity, falling into the feed trough 39. The activated carbon and quartz sand slide downwards along the second piling hole 41, and are ground by the relative rotation of the grinding discs 38 and the grinding shell 12, resulting in the large particles of activated carbon and quartz sand being ground into fine particles. The particles are sprayed out from the bottom of the connecting cavity 36 by high-pressure clean water through the water inlet pipe 19 and the water spray pipe 18. The high-pressure clean water carries away the fine particles after grinding. The fine particles are squeezed by the water flow and squeezed by the rubber sheet 33, and sprayed out from one end of the second mounting cylinder, increasing the proportion of fine particles in the media layer. This ensures that the content of fine particles in the filter media layer is not affected by water washing, thus repairing the filter media layer. The external high-pressure water flow squeezes the rubber sheet 33, thereby blocking the water flow hole 30 inside the second mounting cylinder. This prevents the high-pressure water flow from entering the interior of the grinding shell 12 from the outside of the rubber sheet 33, thus improving the grinding efficiency of the grinding disc 38. After long-term use, the filter media needs to be replaced. Water is sprayed through multiple second mounting cylinders to cause the filter media layer to expand and loosen. When the ball valve on the starting pipe 22 is opened, high-pressure water flows through the starting pipe 22 into the interior of the connecting cylinder 26. The water then flows through the connecting cylinder 26 and the connecting pipe 17 into the spray strip 16 at the bottom edge of one end of the water distribution plate 15. The water is sprayed out through multiple nozzles 43. The reaction force of the water flow causes the water distribution plate 15 to rotate counterclockwise, stopping it at the edge of the lower maintenance port 3. The sealing door outside the lower maintenance port 3 is opened, allowing the medium layer inside the pressure tank 1 to slide out through the lower maintenance port 3, achieving the effect of quickly replacing the medium layer inside the pressure tank 1. Simultaneously, water sprayed from multiple second mounting cylinders cleans the upper surface of the water distribution plate 15, achieving the effect of thoroughly cleaning the water distribution plate 15.Simultaneously, water flow washes away impurities from the surfaces of multiple first mounting cylinders 29, reducing clogging and extending their replacement cycle. The bottom space of the water distribution plate 15 is inspected and cleaned through the middle and lower maintenance ports 3. Excess water is filtered through the filter plates 32 inside the first mounting cylinders 29, flowing into the bottom of the water distribution plate 15 to flush away impurities from the bottom of the pressure tank 1. This is then discharged through the drain port 5, thoroughly removing impurities from the pressure tank 1. After cleaning, high-pressure water is injected into the spray strips 16 at the bottom edge of the other end of the water distribution plate 15 through the branch pipe 23. The reaction force of the high-pressure water causes the water distribution plate 15 to rotate clockwise, restoring it to a horizontal position. A new medium layer is then placed on the upper surface of the water distribution plate 15 through the upper and middle maintenance ports. Multiple pressure tanks 1 can be used simultaneously, with high-pressure water flow shared with adjacent pressure tanks 1 through the water inlet 7, enabling simultaneous operation of multiple pressure tanks 1.
