Description

Technical Field

[0001] The invention relates to the field of water treatment, in particular to a reverse osmosis water treatment device based on a reverse osmosis membrane. Background Art

[0002] Reverse osmosis water treatment equipment is a device that uses RO reverse osmosis technology to treat water. RO reverse osmosis technology uses membrane separation technology. When the pressure added to the system is greater than the osmotic pressure of the influent solution, the water is separated from the solution through a special semi-permeable membrane (reverse osmosis membrane), achieving the purpose of separating, extracting, purifying and concentrating water. Reverse osmosis water treatment equipment does not require heating, and there is no phase change process, so it consumes less energy than traditional methods.

[0003] A Chinese public document (CN111704208A) discloses a reverse osmosis water treatment device based on a reverse osmosis membrane. The document records that by setting a telescopic rotating mechanism and an adsorption driving mechanism, the eccentric weight block is moved back and forth under the action of a first vibration spring and a second vibration spring, driving the stirring rod to rotate, accelerating the water flow rate of the water permeable hole, avoiding the precipitation of calcium carbonate and the like in the water permeable hole of the hollow tube body to form scale, keeping the water permeable hole unobstructed, improving the water treatment efficiency, and achieving a good water treatment effect. The problem that a thick layer of scale is attached to the water permeable hole of the tube body of the existing water treatment device after long-term use, which easily blocks the water permeable hole, resulting in low water treatment efficiency and poor water treatment effect of the water treatment device is solved;

[0004] In the above-mentioned public scheme, a telescopic rotating mechanism is installed inside the reverse osmosis box and an adsorption driving mechanism is designed inside the hollow tube body. The assembly structures in the two mechanisms are exposed to the aqueous solution in the reverse osmosis box. The aqueous solution injected into the reverse osmosis box through the hollow tube body has a slower flow rate. Compared with the precipitates such as calcium carbonate in the aqueous solution that will be deposited in the water permeable holes, the precipitates are more likely to be deposited on the assembly structures of the above-mentioned two mechanisms and form scale. Eventually, the surfaces of the two mechanisms will gradually weaken their effect on removing scale in the water permeable holes due to excessive attachment of precipitates. Summary of the invention

[0035] An assembly ring body 2 is fixedly provided at the center of the top and bottom of the closed water bucket 1, and the assembly ring body 2 is distributed on the outside of the hollow tube body 3. Two convex rings 6 are fixedly mounted on the outer surface of the hollow tube body 3. The two convex rings 6 are respectively located at the upper and lower parts of the hollow tube body 3. A flexible sealing belt 7 is fixedly bonded between the outer surfaces of the assembly ring body 2 and the convex ring 6 on the same side. A group of fourth springs 34 is distributed between each assembly ring body 2 and the hollow tube body 3. Each group of fourth springs 34 has several fourth springs 34, which are equidistantly distributed in the circumferential radial direction. Both ends of the fourth spring 34 are fixed between the assembly ring body 2 and the hollow tube body 3. The flexible sealing belt 7 is made of silicone rubber and has a certain deformation ability. It can also ensure the sealing of the outer wall of the assembly ring body 2 and the convex ring 6.

[0036] The knocking unit includes an elliptical cylinder 10 which is vertically fixed and inserted into the inside of the closed water bucket 1. The elliptical cylinder 10 is hollow. There are two elliptical cylinders 10, which are distributed at equal angles on the periphery of the hollow tube body 3. The angle between the two elliptical cylinders 10 does not exceed ninety degrees. The top and bottom of the closed water bucket 1 are fixedly provided with a fixing plate 4, which is sleeved on the outside of the assembly ring body 2 and the elliptical cylinder 10. The elliptical cylinder 10 is fixedly provided with a plurality of extension cylinders 15 which are distributed at equal distances in a straight line near the side wall of the hollow tube body 3, and the extension cylinder 15 is connected to the elliptical cylinder 10. The interiors are interconnected, and one end of each extension tube 15 away from the elliptical cylinder 10 is against the side wall of the hollow tube body 3. A sliding rod 16 is axially slidably inserted inside each elliptical cylinder 10, and a striking block 17 is fixedly provided at one end of the sliding rod 16 away from the center of the elliptical cylinder 10. A first spring 18 is fixedly provided between the end of the striking block 17 away from the hollow tube body 3 and the extension tube 15, and a driving component is also provided between the hollow tube body 3 and the sliding rod 16, wherein the elliptical cylinder 10 and the interior of the closed water bucket 1 are sealed, that is, the interior of the elliptical cylinder 10 is an independent space.

[0037] The driving component includes a threaded rod 11 which is vertically rotatably arranged inside the hollow tube body 3, and a threaded slider 20 is threadedly sleeved on the outer surface of the threaded rod 11, and the threaded slider 20 is slidably fitted with the hollow tube body 3. The top fixing frame of the closed water bucket 1 is equipped with a driving motor 13, and the ends of the two threaded rods 11 and the output end of the driving motor 13 are fixedly sleeved with synchronous gears 12, and the outer parts of multiple synchronous gears 12 located on the same side are equipped with synchronous toothed belts 14 for transmission, and each sliding rod 16 is fixedly provided with a vertically distributed column 19 at one end close to the threaded slider 20, and a connecting rod 21 is axially slidably embedded inside the threaded slider 20 close to the extension tube 15, and the connecting rod 21 The outer surface of the sleeve is fixed with a ring 22 that slides with the threaded slider 20, and a second spring 23 is arranged between the end of the ring 22 away from the extension tube 15 and the inside of the threaded slider 20. An arc-shaped pressure block 24 is fixedly arranged at the end of the connecting rod 21 close to the extension tube 15. The arc-shaped pressure block 24 is bent downward, and the arc-shaped pressure block 24 is in active contact with the outer surface of the column 19. The driving motor 13 drives the threaded rod 11 to reciprocate inside the elliptical cylinder 10 through the cooperation of the synchronous gear 12 and the synchronous toothed belt 14. Since two end faces of the threaded slider 20 are in sliding fit with the inner wall of the elliptical cylinder 10, when the threaded rod 11 rotates, the threaded slider 20 can slide up and down.

[0038] Working principle: concentrated water to be treated by reverse osmosis enters the interior of the closed water bucket 1 through the concentrated water inlet, and is then discharged from the concentrated water outlet. During the flow, the concentrated water can enter the closed water bucket 1 through the water permeable hole 5. After the concentrated water is treated by the reverse osmosis membrane 8, its pure water will flow into between the reverse osmosis membrane 8 and the closed water bucket 1. During the reverse osmosis treatment, the staff starts the driving motor 13. The driving motor 13 can drive the threaded rod 11 to rotate alternately counterclockwise or clockwise inside the elliptical cylinder 10 through the action of the synchronous gear 12 and the synchronous toothed belt 14, so that the threaded slider 20 can slide up and down inside the elliptical cylinder 10;

[0039] When the threaded slider 20 moves downward, it can push the column 19 through the inner arc surface of the arc-shaped pressure block 24, so that the slide rod 16 slides toward the inside of the elliptical cylinder 10 and compresses the first spring 18 at the same time. Since the arc-shaped pressure block 24 continues to move downward, that is, after the slide rod 16 is pulled to a certain shape by the column 19, the column 19 will be released. At the moment of release, the first spring 18 rebounds quickly and can hit the inner wall of the extension tube 15 with the striking block 17. Since the extension tube 15 is against the surface of the hollow tube body 3, the hollow tube body 3 can also be affected by the vibration force through the conduction of the vibration force. The influence of the vibration force combined with the inclined water permeable hole 5 can effectively prevent the particulate matter in the concentrated water from settling and adhering to the inside of the water permeable hole 5, causing blockage of the water permeable hole 5.

[0040] When the arc-shaped pressing block 24 moves upward with the threaded slider 20 , the column 19 can push the arc-shaped pressing block 24 and the connecting rod 21 into the inside of the threaded slider 20 through the upper arc surface of the arc-shaped pressing block 24 without affecting the normal movement of the threaded slider 20 .

[0041] In the above scheme, the hollow tube body 3 is elastically mounted inside the assembly ring body 2, and during the installation process, the two elliptical cylinders 10 will push the hollow tube body 3 through the extension tube 15, causing the fourth spring 34 between the hollow tube body 3 and the assembly ring body 2 to undergo a slight deformation, so that the striking block 17 can better transmit vibration to the hollow tube body 3 through the extension tube 15.

[0042] Example 2: Please refer to Figure 5 and Figure 6 This embodiment is a further explanation of the first embodiment. The self-cleaning unit includes two symmetrically distributed brackets 26 fixedly mounted on the end face of the threaded slider 20 away from the arc-shaped pressure block 24. A dial wheel 27 is placed between the two brackets 26, and a rotating shaft 25 that rotates and runs through the two brackets 26 is fixedly arranged inside the dial wheel 27. The dial wheel 27 is in contact with the inner wall of the elliptical cylinder 10. Both ends of the rotating shaft 25 are fixedly sleeved with toothless active ratchet wheels 28. The outer side of each toothless active ratchet wheel 28 is meshed with a ratchet bar 29, and the ratchet bar 29 is close to the thread. One end of the slider 20 is slidably equipped with an assembly rod 30, and the end of the assembly rod 30 close to the toothless movable ratchet 28 is fixedly mounted with a blocking ring 33, and a third spring 31 is arranged between the end of the ratchet bar 29 away from the blocking ring 33 and the threaded slider 20, and each ratchet bar 29 is fixedly provided with a knocking block 32 at the end away from the threaded slider 20, and the knocking block 32 is in contact with the inner wall of the elliptical cylinder 10. When the threaded slider 20 moves up and down with the dial wheel 27, the dial wheel 27 is in contact with the elliptical cylinder 10, and the friction force allows the dial wheel 27 to rotate.

[0043] The two sets of toothless active ratchets 28 and ratchet bars 29 distributed at both ends of the rotating shaft 25 are placed inverted. Under the action of the two toothless active ratchets 28 placed inverted to each other, no matter whether the dial wheel 27 rotates clockwise or counterclockwise, one of the ratchet bars 29 can be pushed, and then the ratchet bar 29 can be quickly elastically reset under the action of the third spring 31.

[0044] When the third spring 31 is in a normally extended state, there is a gap between the blocking ring 33 and the ratchet bar 29 , so that the ratchet bar 29 has space for elastic extension.

[0045] The dial wheel 27 is a rubber wheel, and the friction between the dial wheel 27 and the elliptical cylinder 10 is large.

[0046] The dial wheel 27 is a meshing gear, and the inner wall of the elliptical cylinder 10 is fixedly provided with a plurality of teeth distributed vertically and equidistantly, and the dial wheel 27 is movably meshed with the teeth. If the dial wheel 27 is a meshing gear and meshes with the teeth on the inner wall of the elliptical cylinder 10, the stability of the dial wheel 27 rolling up and down can be better guaranteed.

[0047] In this embodiment: no matter whether the dial wheel 27 rotates counterclockwise or clockwise following the movement of the threaded slider 20, there is a set of toothless movable ratchet wheels 28 that intermittently push the ratchet bar 29 and then release it instantly. In conjunction with the action of the third spring 31, the ratchet bar 29 can be quickly reset, and the knocking block 32 at the end of the ratchet bar 29 can knock on the inner wall of the elliptical cylinder 10. Through frequent knocking, vibration self-cleaning treatment is achieved to prevent sediment in the concentrated water from adhering to the surface of the elliptical cylinder 10 and the extension cylinder 15.

[0048] Example 3: Please refer to Figure 8-Figure 10 This embodiment is a further explanation of the second embodiment. The inner wall of each synchronous toothed belt 14 is fitted with a support block 35, and the support block 35 is fixedly assembled with the closed water bucket 1. The side wall of the synchronous toothed belt 14 is fixedly provided with two hinge blocks 36 that are symmetrically distributed up and down, and a pin shaft 37 is assembled between the two hinge blocks 36 through the elastic rotation of a torsion spring. The outer surface of the pin shaft 37 is fixedly sleeved with a trapezoidal shift block 38. The outer surface of the hollow tube body 3 is fixedly provided with a rectangular block 39 near the side wall of the synchronous toothed belt 14, wherein the inclined surface of the trapezoidal shift block 38 faces the hollow tube body 3, the trapezoidal shift block 38 is a right-angled trapezoid, and one of the vertical sides of the rectangular block 39 has been chamfered, and its chamfered vertical side faces the inclined surface of the trapezoidal shift block 38.

[0049] In this embodiment, the threaded rod 11 is replaced with a reciprocating screw rod, that is, the unidirectional rotation of the reciprocating screw rod can make the threaded slider 20 reciprocate up and down inside the elliptical cylinder 10. In this solution, the synchronous toothed belt 14 is attached Figure 8 The state in the middle is maintained to drive clockwise, and the trapezoidal shift block 38 can be moved during the transmission process. The trapezoidal shift block 38 offsets the hollow tube 3 through the rectangular block 39, and then the hollow tube 3 rebounds quickly under the action of the fourth spring 34;

[0050] When the quick rebound of the hollow tube body 3 and the impact of the impact block 17 on the extension tube 15 occur simultaneously, it is similar to that the impact block 17 and the hollow tube body 3 move toward each other and collide, that is, the vibration force is greater, so that the effect of separating the attachments attached to the surface of the hollow tube body 3 and the inner wall of the water permeable hole 5 is better.
