Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis membrane flushing, in particular to a reverse osmosis membrane flushing device for a water purifier. Background Art

[0002] The reverse osmosis membrane module has strong pressure resistance, stable operation, low cost and high desalination rate, and is applicable to different fields such as the desalination treatment of high-concentration seawater, the desalination of high-concentration brackish water, and the concentration and recovery of valuable substances such as electroplated metals. The main reason for the decline in the performance of the reverse osmosis membrane is that the membrane surface is contaminated, such as surface scaling, membrane surface blockage or physical and chemical changes of the membrane itself. When the reverse osmosis membrane is contaminated, it needs to be cleaned in time, otherwise it will affect the water quality and output. Therefore, a flushing device is required to clean the reverse osmosis membrane.

[0003] The utility model patent with the publication number of CN 221015412 U discloses a flushing device for a reverse osmosis membrane module, including a cleaning tank. An electric sliding table is arranged above the cleaning tank. A hydraulic rod is connected to the bottom of the electric sliding table. A flushing nozzle is installed at the bottom of the piston of the hydraulic rod. The inner and outer sides of the cleaning tank are connected with a recovery component. For the flushing device for the reverse osmosis membrane module, through the cooperation of the electric sliding table and the hydraulic rod, it is responsible for controlling the horizontal movement of the flushing nozzle and adjusting the distance between the flushing nozzle and the cleaning tank respectively, so as to adjust the water pressure when flushing the reverse osmosis membrane, improve the flushing efficiency and expand the adjustment range. At the same time, by setting a corrugated hose, it is convenient to connect the moving flushing nozzle and the fixed connecting pipe to ensure the stable transmission of the water liquid. By setting a filter plate and a water pump, the filtered water liquid can be recycled, which is convenient for the user to use.

[0004] However, there are still some disadvantages in the actual use of the above device. The more obvious one is that when flushing the reverse osmosis membrane, the device uses a chuck to clamp the reverse osmosis membrane, and it is easy to cause the reverse osmosis membrane to fall off due to excessive impact force during the flushing process, which damages the reverse osmosis membrane. Moreover, the clamping force cannot be adjusted according to the thickness of the reverse osmosis membrane to be flushed. If the reverse osmosis membrane is too thin, it is easy to fall off during the flushing process. If the reverse osmosis membrane is too thick, it is easy to cause damage to the clamped part of the reverse osmosis membrane due to excessive clamping force. In addition, since the device is a closed structure, when clamping and replacing the reverse osmosis membrane, it is difficult for the operator to quickly complete the clamping and replacement of the reverse osmosis membrane due to the small operation space, resulting in a large operation difficulty, wasting a lot of time and reducing the flushing efficiency.

[0005] Therefore, it is very necessary to invent a reverse osmosis membrane flushing device for a water purifier to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a reverse osmosis membrane flushing device for a water purifier. By setting a fixing mechanism, it aims to solve the problems mentioned in the above background technology.

Moreover, the clamping force cannot be adjusted according to the thickness of the reverse osmosis membrane to be flushed. If the reverse osmosis membrane is too thin, it is likely to fall off during the flushing process. If the reverse osmosis membrane is too thick, the clamped part of the reverse osmosis membrane is likely to be damaged due to excessive clamping force. In addition, since the device is a closed structure, when clamping and replacing the reverse osmosis membrane, it is difficult for the operator to quickly complete the clamping and replacement of the reverse osmosis membrane due to the small operating space, resulting in a large waste of time and a reduction in flushing efficiency.

[0025] The present disclosure will be further described in detail below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant content and do not limit the present disclosure. In addition, it should be noted that for the sake of convenience of description, only the parts related to the present disclosure are shown in the drawings.

[0026] As Figures 1-4 shown, the reverse osmosis membrane flushing device of the present disclosure may include components such as a housing assembly 1, a reciprocating mechanism 2, a flushing mechanism 3, and a fixing mechanism 4.

[0027] As Figure 2 shown, in the present disclosure, the housing assembly 1 includes a housing main body 11, a sliding limit groove 12, an ear plate 13, and a drain pipe 14. Among them, the sliding limit groove 12 is opened on the surface of the housing main body 11 and penetrates the housing main body 11, the ear plate 13 is fixedly connected above the housing main body 11, and the drain pipe 14 is fixedly connected to the outside of the bottom of the housing main body 11 and passes through the housing main body 11.

[0028] Thus, the accumulated water inside the housing main body 11 is discharged through the drain pipe 14.

[0029] As Figures 2-3As shown, in a preferred embodiment, the reciprocating mechanism 2 includes a rotating frame 21, a sliding groove 22, a first motor 23, a screw rod 24, a moving plate 25 and a handle 26. Among them, the rotating frame 21 is rotatably connected to the ear plate 13 through a pin shaft and is located above the housing main body 11. The sliding groove 22 is opened on the inner wall of the rotating frame 21. The first motor 23 is fixedly connected to the outside of the rotating frame 21 and the motor brush-out end passes through the rotating frame 21. One end of the screw rod 24 is fixedly connected to the output end of the first motor 23 and the other end is rotatably connected to the inner wall of the mounting frame. The moving plate 25 is slidably connected to the rotating frame 21 through the sliding groove 22. The screw rod 24 is threadedly connected to one end plate and passes through the moving plate 25. The handle 26 is fixedly connected to the outside of the rotating frame 21.

[0030] Thus, when the operator fixes and takes the reverse osmosis membrane, the operator can drive the rotating frame 21 to rotate by pulling the handle 26, which is convenient for the operator to fix and take the reverse osmosis membrane. When flushing the reverse osmosis membrane, the operator first turns on the first motor 23 to rotate. The rotation of the first motor 23 drives the screw rod 24 to rotate. The rotation of the screw rod 24 drives the moving plate 25 to move. The reverse osmosis membrane is flushed in all directions through the cooperation of the moving plate 25 and the flushing mechanism 3.

[0031] As Figure 3 shown, in the present disclosure, the flushing mechanism 3 includes a water pump 31, a water inlet hose 32, a water outlet hose 33, a hydraulic cylinder 34, a water tank 35 and a spray head 36. Among them, the water pump 31 is fixedly connected above the moving plate 25. The water inlet hose 32 is fixedly connected above the water pump 31. One end of the water outlet hose 33 is fixedly connected to the outside of the water pump 31. The hydraulic cylinder 34 is fixedly connected above the moving plate 25 and the output end of the hydraulic cylinder 34 passes through the moving plate 25. The water tank 35 is fixedly connected below the output end of the hydraulic cylinder 34. The other end of the water outlet hose 33 is fixedly connected to the top of the water tank 35. The spray head 36 is fixedly connected below the water tank 35.

[0032] Thus, when flushing the reverse osmosis membrane, the operator turns on the water pump 31. The water pump 31 pumps the external water into the water pump 31 through the water inlet hose 32 and then transports the water to the inside of the water tank 35 through the water outlet hose 33. Then, the operator turns on the hydraulic cylinder 34 to drive the water tank 35 to move to adjust the height and flushing water pressure, and then flushes the reverse osmosis membrane through the spray head 36.

[0033] As Figure 4As shown, in a preferred embodiment, the fixing mechanism 4 includes a second motor 41, a gear 42, a sliding plate 43, a toothed plate 44, a notch 45, a lower fixing plate 46, an adjusting bolt 47, and an upper fixing plate 48. Among them, the second motor 41 is fixedly connected to the outside of the housing main body 11, the gear 42 is fixedly connected to the outside of the output end of the second motor 41, both ends of the sliding plate 43 are slidably connected to the housing main body 11 through sliding limit grooves 12, the toothed plate 44 is fixedly connected to the outside of the sliding plate 43 and meshes with the gear 42, the notch 45 is formed on the surface of the sliding plate 43, the lower fixing plate 46 is fixedly connected to the outside of the bottom of the sliding plate 43, the adjusting bolt 47 is threadedly connected to the sliding plate 43 and passes through the sliding plate 43, one end of the adjusting bolt 47 is rotatably connected to the inner wall of the sliding plate 43 through a bearing, and the upper fixing plate 48 is threadedly sleeved on the outside of the adjusting bolt 47 and is located inside the notch 45.

[0034] Thus, the operator first turns on the second motor 41 according to the size of the reverse osmosis membrane to be rinsed. The rotation of the second motor 41 drives the gear 42 to rotate. The rotation of the gear 42 drives the two toothed plates 44 to move. The movement of the toothed plates 44 drives the two sliding plates 43 to move towards each other. When the sliding plates 43 move to a suitable position, the operator places the reverse osmosis membrane above the lower fixing plate 46, and then rotates the adjusting bolt 47 to drive the upper fixing plate 48 to move and stably clamp and fix the reverse osmosis membrane.
