Description

Technical Field

[0001] This invention relates to the field of bypass water treatment equipment technology, specifically a bypass water treatment device. Background Technology

[0002] During the operation of a circulating water system, calcium and magnesium ions, suspended solids, bacteria, and algae in the water will continuously accumulate, leading to pipe scaling, equipment corrosion, reduced heat exchange efficiency, and even the growth of harmful microorganisms such as Legionella, affecting the normal operation of the system and shortening the service life of equipment. Bypass water treatment, as a key means of water quality control in circulating water systems, can effectively solve the above problems by extracting 1%-5% of the main circulating water for targeted treatment, without requiring shutdown and without affecting the operation of the main process.

[0003] For example, the utility model patent with publication number CN204699485U discloses a bypass water processor that adopts a structure combining coarse filtration and main filtration. Although it alleviates the problem of filter clogging to a certain extent, it cannot prevent the microcrystals formed by calcium and magnesium ions in the water from entering the main circulation pipeline from the outlet pipe during the cleaning process, which may lead to the pollution of the main circulation pipeline. Summary of the Invention

[0004] The purpose of this invention is to provide a bypass water treatment device to solve the problems mentioned in the background art.

The cleaning mechanism includes a sleeve. A scraper and a second brush are provided in the inner cavity of the sleeve. A drive mechanism for driving the cleaning mechanism to rotate is provided in the middle of the inner cavity of the treatment chamber. When the drive mechanism rotates counterclockwise, the second brush and the scraper rotate clockwise around the center of the treatment chamber. When the drive mechanism rotates clockwise, the second brush rotates 180° and then rotates counterclockwise around the center of the treatment chamber, while the scraper remains stationary.

[0008] As a further aspect of the present invention: an anode generator is fixedly connected to the upper middle part of the mounting plate away from the cathode generator, and symmetrical through grooves are provided on the outer wall of the sleeve, with a filter screen fixedly connected to the inner cavity of the through groove.

[0009] As a further embodiment of the present invention: both ends of the inner cavity of the sleeve are fixedly connected to a fixing ring, and a rotating plate is attached to the end of the fixing ring near the cathode generator. The middle part of the upper rotating plate is rotatably connected to the outer wall of the cathode generator. A connecting ring is fixedly connected to the top of the upper rotating plate, and a through pipe is fixedly connected to the bottom of the lower rotating plate. A drive gear is fixedly connected to the outer wall of the connecting ring and the through pipe at the end away from the rotating plate.

[0010] As a further aspect of the present invention: the driving mechanism includes a servo motor, the output end of which is fixedly connected to a transmission rod, the transmission rod being rotatably connected to the middle of the mounting plate, symmetrical transmission gears being fixedly connected to the outer wall of the transmission rod, the position of the transmission gears corresponding to the driving gears, the transmission gears meshing with the driving gears, a connecting rod being fixedly connected to the side of the driving gear near the sleeve, an arc-shaped groove being opened at the upper end of the rotating plate, the arc-shaped groove corresponding to the position of the connecting rods, and a brush plate being fixedly connected together between the symmetrical connecting rods.

[0011] As a further aspect of the present invention: the second brush plate is located between symmetrical arc-shaped grooves, and rotating rods are fixedly connected to both ends of the second brush plate. The rotating rods are slidably connected within the arc-shaped grooves. Both the second brush plate and the first brush plate are composed of vertical plates and bristles. A symmetrical drive rod is fixedly connected to one side of the second brush plate. The drive rod is located on the side of the outer wall of the second brush plate away from the bristles. A rack is fixedly connected to the middle of the arc-shaped groove near the cathode generator. A driven gear is fixedly connected to the outer wall of the arc-shaped groove, and the driven gear meshes with the rack.

[0012] As a further aspect of the present invention: the two ends of the scraper are fixedly connected to fixing blocks, the fixing blocks are positioned corresponding to the drive rod, the rotating plate has an annular groove on the side near the fixing block, and the end of the fixing block away from the scraper is slidably connected in the groove.

[0013] As a further aspect of the present invention: an annular groove is provided at one end of the fixed ring near the rotating plate, and a slider is slidably connected to the inner cavity of the annular groove near the brush plate two. The slider is rotatably connected to the end of the rotating rod away from the brush plate two.

[0014] As a further embodiment of the present invention: a sliding rod is fixedly connected to the end of the rotating rod away from the brush plate 2, and the end of the sliding rod away from the rotating rod is slidably connected to the positioning block perpendicularly. The positioning block and the rotating rod are elastically connected by a spring, and the spring is sleeved on the outer wall of the sliding rod.

[0015] As a further aspect of the present invention: the positioning block has an inclined surface at the end away from the rotating rod, and a number of uniformly spaced locking blocks are fixedly connected to the inner cavity of the annular groove on the side away from the slider. A locking groove is formed between two adjacent locking blocks, and a symmetrical inclined surface is formed at the end of the locking block near the rotating rod, with the inclined surface fitting against the inclined plane.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] By applying a low-voltage superimposed pulsed electric field to the anode and cathode generators, calcium and magnesium ions in the water are induced to form easily cleanable aragonite-type calcium carbonate microcrystals, rather than hard calcite scale. This prevents scaling in pipes and equipment from the source, ensuring the heat exchange efficiency of the circulating water system and reducing equipment corrosion. After the scraper of the cleaning mechanism removes the microcrystals from the outer wall of the cathode, brush plate one and brush plate two work together to push the microcrystals back and capture them in the sleeve. Combined with the filter screen of the sleeve through the groove, the microcrystals are prevented from passing through the filter screen and entering the treatment chamber, thus preventing them from flowing back to the main circulation pipeline through the outlet pipe, solving the core pollution problem of existing equipment. The bidirectional rotation of the drive mechanism can switch between two working modes. It can efficiently scrape off microcrystals and clean the filter screen to prevent blockage, while brush plate two can self-clean the cathode generator and scraper to avoid microcrystal debris residue and ensure the continuous treatment effect of the equipment.

[0030] Please see Figure 1-4 In this embodiment of the invention, a bypass water treatment device includes a base 1 and a treatment chamber 3. An installation plate 7 is fixedly connected to the upper part of the inner cavity of the treatment chamber 3. A cathode generator 15 is fixedly connected to the middle of one side of the installation plate 7. A cleaning mechanism for cleaning the outer wall of the cathode generator 15 is provided. The cleaning mechanism includes a sleeve 9, which is sleeved on the outer wall of the cathode generator 15. A scraper 17 and a second brush plate 16 are provided in the inner cavity of the sleeve 9. A driving mechanism for driving the cleaning mechanism to rotate is provided in the middle of the inner cavity of the treatment chamber 3. When the driving mechanism rotates counterclockwise, the second brush plate 16 and the scraper 17 rotate clockwise around the center of the treatment chamber 3. When the driving mechanism rotates clockwise, the second brush plate 16 rotates 180° and then rotates counterclockwise around the center of the treatment chamber 3. At this time, the scraper 17 remains stationary. The scraper 17 is spiral-shaped and can fit tightly against the outer wall of the cathode generator 15.

[0031] A filter bucket 2 and a treatment chamber 3 are fixedly connected to the upper middle part of the base 1. A water inlet pipe is fixedly connected to one side of the lower end of the filter bucket 2, and a water outlet pipe is fixedly connected to the lower side of the treatment chamber 3 away from the filter bucket 2. Both the water outlet pipe and the water inlet pipe are connected to the main circulation pipeline. The filter bucket 2 and the treatment chamber 3 are connected by a pipe. When treating the bypass water, the water flows into the inner cavity of the filter bucket 2 through the water inlet pipe. A filter element 5 is fixedly connected to the lower part of the inner cavity of the filter bucket 2. After the water flows through the filter element 5 to filter and remove impurities, the water flows into the inner cavity of the treatment chamber 3 through the pipe. A drain pipe 4 is fixedly connected to the middle part of the base 1. The top of the drain pipe 4 is connected to the bottom of the inner cavity of the filter bucket 2 and the treatment chamber 3 respectively. When it is necessary to clean the impurities accumulated in the inner cavity of the filter bucket 2 and the treatment chamber 3, the valve of the drain pipe 4 can be opened to discharge the impurities through the drain pipe 4.

[0032] Please see Figure 3-7 An anode generator 8 is fixedly connected to the upper middle part of the mounting plate 7, away from the cathode generator 15. The cooperation of the anode generator 8 and the cathode generator 15 applies a low-voltage superimposed pulsed electric field to the water flow, inducing calcium and magnesium ions in the water to form microcrystals. These microcrystals are aragonite-type calcium carbonate, not hard calcite scale, allowing them to adhere to the outer surface of the cathode generator 15. The microcrystals formed on the surface of the cathode generator 15 can be cleaned by rotating the scraper 17. Symmetrical through grooves 34 are provided on the outer wall of the sleeve 9, and the inner cavity of the through grooves 34 is fixedly connected to… With a filter screen, the water in the inner cavity of the treatment chamber 3 will enter the inner cavity of the sleeve 9 through the through groove 34, thus ensuring that the water can simultaneously surround the anode generator 8 and the cathode generator 15. This ensures that the calcium and magnesium ions in the water can form microcrystals on the outer wall of the cathode generator 15, and the filter screen in the inner cavity of the through groove 34 can prevent microcrystals falling from the cathode generator 15 from entering the inner cavity of the treatment chamber 3 through the sleeve 9, and prevent microcrystals from re-entering the main circulation pipe through the outlet pipe, thereby polluting the water in the main circulation pipe.

[0033] Both ends of the inner cavity of the sleeve 9 are fixedly connected to fixing rings 20. A rotating plate 19 is fitted to the end of the fixing ring 20 closest to the cathode generator 15. The middle of the upper rotating plate 19 is rotatably connected to the outer wall of the cathode generator 15. A connecting ring 33 is fixedly connected to the top of the upper rotating plate 19, and a through pipe 18 is fixedly connected to the bottom of the lower rotating plate 19. Drive gears 13 are fixedly connected to the outer walls of both the connecting ring 33 and the through pipe 18 at their ends away from the rotating plate 19. The drive mechanism includes a servo motor 6. A transmission rod 10 is fixedly connected to the output end of the servo motor 6. The transmission rod 10 is rotatably connected to the middle of the mounting plate 7. Symmetrical transmission gears 14 are fixedly connected to the outer wall of the transmission rod 10. The positions of the transmission gears 14 correspond to the drive gears 13. 4 meshes with the drive gear 13. When the servo motor 6 drives the transmission rod 10 to rotate, it will drive the drive gear 13 to rotate synchronously through the transmission gear 14, thereby causing the rotating plate 19 to rotate synchronously with the drive gear 13. The drive gear 13 is fixedly connected to the side of the sleeve 9 with a connecting rod 12. The upper end of the rotating plate 19 is provided with an arc-shaped groove 24, which corresponds to the position of the connecting rod 12. The symmetrical connecting rods 12 are fixedly connected to a brush plate 11. When the drive gear 13 rotates, it will drive the brush plate 11 to rotate synchronously. The brush plate 11 will clean the filter screen in the cavity of the through groove 34 during the rotation process, thereby preventing the microcrystals from falling off the cathode generator 15 and flowing with the water to block the filter screen.

[0034] Please see Figure 6-8 During the cleaning process of the filter screen by brush plate 11, the microcrystals are pushed back into the inner cavity of sleeve 9 by brush plate 11, ensuring that the microcrystals, after being swept away, will not pass through the filter screen and contaminate the water quality of the outlet pipe. Brush plate 26 is located between the symmetrical arc grooves 24. Both ends of brush plate 26 are fixedly connected to rotating rods 23, which are slidably connected in the arc grooves 24. When the drive gear 13 drives the rotating plate 19 to rotate, the rotating rods 23 will slide relatively in the inner cavity of the arc grooves 24. Only when the outer wall of the rotating rods 23 contacts one side of the inner cavity of the arc grooves 24 will they rotate synchronously with the rotating plate 19. Meanwhile, brush plate 11 will be driven by the gear 13 to rotate. When wheel 13 rotates synchronously, there will be an angular difference between brush plate 11 and brush plate 16. That is, brush plate 11 will contact the filter screen before drive gear 13. When transmission gear 14 rotates counterclockwise, it will drive drive gear 13 and rotating plate 19 to rotate clockwise synchronously. Then brush plate 11 will contact the filter screen before drive gear 13. Brush plate 11 contacts the outer side of the filter screen, and brush plate 16 contacts the inner side of the filter screen. The microcrystals swept off by brush plate 11 will be immediately captured by brush plate 16, further preventing microcrystals from passing through the filter screen. Both brush plate 16 and brush plate 11 are composed of vertical plates and bristles.

[0035] Furthermore, during the rotation of the second brush plate 16, it continuously comes into contact with the water flow, thereby self-cleaning the second brush plate 16. A symmetrical drive rod 22 is fixedly connected to one side of the second brush plate 16. The drive rod 22 is located on the outer wall of the second brush plate 16 away from the bristles. A rack 26 is fixedly connected to the middle of the arc-shaped groove 24 near the cathode generator 15. A driven gear 25 is fixedly connected to the outer wall of the arc-shaped groove 24. The driven gear 25 meshes with the rack 26. Therefore, during the rotation of the arc-shaped groove 24 driven by the rotating plate 19, the water flow will be cleaned through the rack 26 and the driven gear 25. The rotating rod 23 and the second brush plate 16 rotate in coordination. When the rotating plate 19 rotates clockwise, the rotating rod 23 contacts one side of the inner cavity of the arc groove 24. At this time, the second brush plate 16 will be located on the side closer to the first brush plate 11. That is, the driving rod 22 will be away from the position of the first brush plate 11. When the rotating plate 19 rotates counterclockwise, the rotating rod 23 contacts the other side of the inner cavity of the arc groove 24. At this time, the second brush plate 16 will rotate clockwise to the side closer to the cathode generator 15, thereby driving the driving rod 22 to rotate clockwise away from the position of the cathode generator 15.

[0036] Fixed blocks 21 are fixedly connected to both ends of the scraper 17. The fixed blocks 21 correspond to the positions of the drive rod 22. An annular groove is provided on the side of the rotating plate 19 near the fixed blocks 21. The end of the fixed block 21 away from the scraper 17 is slidably connected in the groove, so that the fixed block 21 can rotate around the center of the cathode generator 15. When the second brush plate 16 is close to the position of the first brush plate 11, the drive rod 22 and the fixed blocks 21 are in contact with each other. Figure 8 As shown, when the rotating plate 19 drives the brush plate 16 to rotate, the drive rod 22 and the fixed block 21 will push the scraper 17 to rotate synchronously around the center of the cathode generator 15, thereby cleaning the microcrystals on the outer wall of the cathode generator 15 through the scraper 17.

[0037] Please see Figure 7-9The transmission between the rack 26 and the driven gear 25 drives the rotating rod 23 and the second brush plate 16 to rotate 180° clockwise or counterclockwise. When the rotating plate 19 rotates clockwise, it drives the rotating rod 23 to rotate synchronously, thereby adjusting the position of the second brush plate 16. When the driving rod 22 approaches the position of the first brush plate 11, and the fixing block 21 is in contact with the driving rod 22, the first brush plate 11, the second brush plate 16, and the scraper 17 will rotate synchronously to clean the filter screen, thus cleaning the microcrystals on the outer wall of the cathode generator 15. The microcrystals scraped off by the scraper 17 will be swept off by the brush plate 16. When the rotating plate 19 rotates counterclockwise, the rotating rod 23 will rotate 180° clockwise through the rotation of the rack 26 and the driven gear 25. This will cause the bristles on the brush plate 16 to contact the outer wall of the cathode generator 15, and the driving rod 22 will separate from the fixed block 21. As the brush plate 16 rotates counterclockwise with the rotating plate 19, the scraper 17 will remain stationary. The outer wall of the cathode generator 15 and the scraper 17 can then be cleaned by the brush plate 16 to prevent the residue of microcrystal debris.

[0038] Furthermore, when the second brush plate 16 contacts the cathode generator 15, the scraper 17 remains stationary. This prevents the brush plate 16 from cleaning the outer wall of the cathode generator 15. Since the bristles are typically quite long, ensuring cleaning efficiency, some bristles may bend upon contact with the outer wall of the cathode generator 15. If the scraper 17 is in motion at this time, it might break these bent bristles, thus affecting the subsequent cleaning of the filter screen by the second brush plate 16. Also, if the scraper 17 rotates synchronously with the second brush plate 16, the bristles cannot effectively clean the outer wall of the scraper 17. The combination of brush plate 11, brush plate 16 and scraper 17 allows the microcrystals formed on the outer wall of cathode generator 15 to be quickly cleaned, while preventing floating microcrystals from clogging the filter screen. The top of the through pipe 18 is fixedly connected to the rotating plate 19 located below, and the through pipe 18 is connected to the inner cavity of the sleeve 9. When sewage is discharged through the drain pipe 4, the floating microcrystals and water flow in the inner cavity of the through pipe 18 will enter the drain pipe 4 from the inner cavity of the sleeve 9 through the through pipe 18, thereby discharging the water flow and microcrystals in the inner cavity of the sleeve 9, thus completing the cleaning of the microcrystals in the inner cavity of the sleeve 9.

[0039] When the rotating plate 19 rotates, it will drive the arc-shaped groove 24 to rotate synchronously. In order to prevent the rotating rod 23 from rotating axially around the center of the cathode generator 15 while the arc-shaped groove 24 is rotating relative to the rotating rod 23, that is, if the rotating rod 23 is prematurely driven to rotate axially around the center of the cathode generator 15 due to the friction between the arc-shaped groove 24 and the rotating rod 23, the rotating rod 23 will not be able to drive the brush plate 16 to rotate 180°. Then the brush plate 16 will not be able to clean the cathode generator 15 and the filter screen effectively. Therefore, it is necessary to ensure that the rotating rod 23 and the brush plate 16 can only rotate synchronously with the rotating plate 19 after rotating 180°. This way, the brush plate 16 can clean the microcrystals and avoid clogging of the filter screen.

[0040] Please see Figure 6-11 An annular groove 29 is provided at the end of the fixed ring 20 near the rotating plate 19. A slider 27 is slidably connected to the inner cavity of the annular groove 29 near the brush plate 16. The slider 27 is rotatably connected to the end of the rotating rod 23 away from the brush plate 16. A sliding rod 35 is fixedly connected to the end of the rotating rod 23 away from the brush plate 16. The end of the sliding rod 35 away from the rotating rod 23 is slidably connected perpendicularly to the positioning block 28. The positioning block 28 and the rotating rod 23 are elastically connected by a spring, and the spring is sleeved on the sliding rod 35. When the positioning block 28 is subjected to a vertically downward force, the positioning block 28 will move toward the position of the rotating rod 23 and then retract into the inner cavity of the slider 27. The end of the positioning block 28 away from the rotating rod 23 has an inclined surface 32. Several uniformly spaced locking blocks 31 are fixedly connected to the side of the inner cavity of the annular groove 29 away from the slider 27. A locking groove 30 is provided between two adjacent locking blocks 31. The end of the locking block 31 near the rotating rod 23 has a symmetrical inclined surface, and the inclined surface fits against the inclined surface 32.

[0041] Since the positioning block 28 has an inclined surface 32 on only one side of the end away from the rotating rod 23, during the process of the rotating rod 23 driving the positioning block 28 to rotate, that is, during the process of the rotating plate 19 driving the rotating rod 23 to rotate clockwise, as Figure 11As shown, during the rotation of the positioning block 28, the inclined surface 32 contacts the inclined surface on the locking block 31, causing the positioning block 28 to retract into the slider 27. At this time, the positioning block 28 will not hinder the movement of the rotating rod 23. If the rotating plate 19 rotates counterclockwise at this time, since the inclined surface 32 on the positioning block 28 can only contact one side of the inclined surface, the locking block 31 will block the side of the positioning block 28 that does not have an inclined surface when the rotating plate 19 rotates counterclockwise. Therefore, the rotating rod 23 and the positioning block 28 cannot immediately change direction, so the positioning block 28 and the rotating rod 23 will not immediately rotate counterclockwise with the rotating plate 19. Only after the rotating rod 23 and the positioning block 28 rotate 180°, and the inclined surface 32 contacts the inclined surface on the other side of the locking block 31, will the rotating rod 23 rotate counterclockwise with the rotating plate 19. Thus, through the cooperation of the locking block 31, the locking groove 30 and the inclined surface 32, it is ensured that the rotating rod 23 can only rotate synchronously with the rotating plate 19 after completing its rotation.
