Description

Technical Field

[0001] This utility model belongs to the field of reverse osmosis technology, specifically relating to a high-efficiency reverse osmosis device that prevents scaling and operates at critical speeds. Background Technology

[0002] A reverse osmosis membrane is an artificial semi-permeable membrane with specific properties, mimicking a biological semi-permeable membrane. It is the core component of reverse osmosis technology. The principle of reverse osmosis is based on the principle that, under pressure higher than the osmotic pressure of the solution, other substances cannot pass through the semi-permeable membrane, thus separating them from water. The membrane pores of a reverse osmosis membrane are extremely small, thus effectively removing dissolved salts, colloids, microorganisms, organic matter, and other pollutants from water. The system offers advantages such as high water quality, low energy consumption, no pollution, simple process, and easy operation.

[0003] Referring to Chinese Patent CN216799386U, a device for preventing scaling of reverse osmosis membranes is disclosed, comprising a filter cartridge, a filtration mechanism, a connecting mechanism, a driving mechanism, an arc-shaped guide groove, and an annular sealing gasket. The filtration mechanism is located within the filter cartridge and includes a filter chamber, an inlet pipe, a hollow tube, a drain hole, a reverse osmosis membrane, a connecting plate, an outlet pipe, an annular slider, and a cleaning brush. The filter chamber is located within the filter cartridge. The inlet pipe is fixedly installed on the upper side wall of the filter cartridge and communicates with the interior of the filter chamber. The hollow tube is vertically installed within the filter chamber, and the drain hole is located on the outer side wall of the hollow tube and communicates with its interior. The reverse osmosis membrane is wrapped around the outer side wall of the hollow tube. The connecting plate is installed at the lower end of the hollow tube and abuts against the lower side wall of the filter cartridge. This utility model provides a device for preventing scaling of reverse osmosis membranes, which has the advantages of preventing scaling and improving service life.

[0004] In the above technical solution, a drive mechanism is used to control the up-and-down sliding of an annular slider in the filter chamber, thereby allowing the cleaning brush fixed on the inner wall of the annular slider to clean the reverse osmosis membrane and remove impurities from its surface. This up-and-down sliding cleaning method is slow and ineffective, requiring waiting for the annular slider to move back and forth to complete the cleaning. Furthermore, the cleaning mechanism itself cannot perform self-cleaning on the inner wall of the filter cartridge, failing to provide a clean working space for the membrane module. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency reverse osmosis device that prevents scaling and operates at critical speeds, thereby solving the problems of membrane cleaning and filter cartridge self-cleaning in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency reverse osmosis device for preventing scaling and critical operation includes a support frame on which a filter cartridge is supported and installed. A permeation membrane assembly is installed inside the filter cartridge, and a central tube is installed inside the permeation membrane assembly. A cleaning component is included. Top rings are provided at both ends of the inner wall of the filter cartridge, and a bushing is installed at one end of the filter cartridge. A transmission disc is movably connected between the top rings and the bushing. A driven tooth is provided at the center of the transmission disc, and a drive mechanism is output from one side of the driven tooth.

[0008] Several connecting rods are installed on the transmission disc, and the connecting rods are connected to the cleaning assembly, which covers the outer wall of the filter cartridge;

[0009] Furthermore, the drive mechanism includes a motor mounted on a support frame, the output end of the motor is connected to a gearbox, and the output end of the gearbox is equipped with transmission gears that mesh with driven gears.

[0010] Furthermore, the cleaning assembly includes an annular shell, one end of which is connected to a transmission disk via a connecting rod. The annular shell is concentrically fitted with the permeation membrane assembly. A first brush strip is arranged around the inner wall of the annular shell, and the first brush strip contacts the outer wall of the annular shell.

[0011] Furthermore, several annular shells are evenly distributed, and connecting plates are arranged in a ring between these annular shells. The cleaning fluid injected into the filter cartridge, through the evenly distributed annular shells, can easily enter and directly contact the outer wall of the permeate membrane module, improving cleaning uniformity and efficiency. Combined with the rotation of the annular shells, the first brush strip enables rapid cleaning of the outer wall of the permeate membrane module. Simultaneously, the multi-segment annular shell design significantly reduces the weight of the overall cleaning assembly, lessening the burden on the equipment and improving its stability.

[0012] Furthermore, a wiping strip is provided on the top of the connecting plate, and the wiping strip is attached to the inner wall of the filter cartridge. When the annular shell rotates, the wiping strip can remove the scale generated on the inner wall of the filter cartridge, realizing a self-cleaning function, ensuring the cleanliness of the inner wall of the filter cartridge, and also providing a clean working space for the permeate membrane module.

[0013] Furthermore, a second brush strip is provided below the connecting plate, and the second brush strip is distributed between each annular shell. Each annular shell is spaced apart, and there is no brush strip covering the outer wall of the permeate membrane assembly in the gaps. The second brush strip below the connecting plate can make up for the problem of no brush strip covering the gaps. In this way, by rotating the cleaning component, together with the cleaning of the first and second brush strips, the outer wall of the permeate membrane assembly can be fully covered, ensuring that the brush strips are effective in cleaning.

[0014] The technical solution of this utility model has the following beneficial effects:

[0015] 1. The rotation of the annular shell and the cleaning action of the first and second brush strips ensure comprehensive coverage of the outer wall of the membrane module, guaranteeing effective cleaning. A clean membrane module maintains its optimal filtration performance, thereby improving the overall system's filtration efficiency and stability. Simultaneously, the wiping strips above the annular shell remove scale buildup on the inner wall of the filter cartridge, achieving a self-cleaning function and ensuring the cleanliness of the filter cartridge's inner wall. This provides a clean working space for the membrane module. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] Example 1:

[0027] refer to Figure 1 A high-efficiency reverse osmosis device for preventing scaling and critical operation includes a support frame 10, on which a filter cartridge 11 is supported and installed. A permeate membrane assembly 12 is installed inside the filter cartridge 11, and a central tube 121 is installed inside the permeate membrane assembly 12. A cleaning component 30 is included. Top rings 122 are provided at both ends of the inner wall of the filter cartridge 11. A bushing 21 is installed at one end of the filter cartridge 11. A transmission disk 20 is movably connected between the top rings 122 and the bushing 21. A driven tooth 22 is provided at the center of the transmission disk 20, and a drive mechanism is output from one side of the driven tooth 22.

[0028] In the above scheme, the drive mechanism is configured to drive the driven gear 22 to rotate, that is, the transmission disk 20 rotates between the top ring 122 and the bushing 21.

[0029] refer to Figures 1-4 The drive mechanism includes a motor 261, which is mounted on a support frame 10. The output end of the motor 261 is connected to a gearbox 26, and the output end of the gearbox 26 is equipped with a transmission gear 25, which meshes with the driven gear 22.

[0030] In the above scheme, the starter motor 261 transmits power to the gearbox 26. With the transmission gear 25 and the driven gear 22 meshing with each other, the transmission disk 20 is driven to rotate through gear transmission.

[0031] refer to Figure 3 and Figure 4 A plurality of connecting rods 23 are mounted on the transmission disc 20, and the connecting rods 23 are connected to the cleaning assembly 30, which covers the outer wall of the filter cartridge 11. The connecting rods 23 are equidistantly distributed around the transmission disc 20 and are interconnected with the cleaning assembly 30, so that the transmission disc 20 and the cleaning assembly 30 are synchronized. When the transmission disc 20 rotates, the torque is transmitted to the cleaning assembly 30 through the multiple connecting rods 23 to rotate. Since the cleaning assembly 30 covers the outer wall of the filter cartridge 11, it can clean the scale generated on the outer wall of the permeate membrane module 12, improve the cleaning efficiency, and ensure the uniformity and thoroughness of the cleaning. A nut 24 is installed at one end of the connecting rod 23, and the nut 24 is used to stabilize the installation of the transmission disc 20 and the cleaning assembly 30.

[0032] Further reference Figure 3 and Figure 4 The cleaning assembly 30 includes an annular shell 31. One end of the annular shell 31 is connected to the transmission disk 20 via a connecting rod 23. The annular shell 31 is concentrically fitted with the permeation membrane assembly 12. The inner wall of the annular shell 31 is surrounded by a first brush strip 32, which contacts the outer wall of the annular shell 31.

[0033] In a further implementation, the drive motor 261 drives the transmission disc 20 to rotate, and the transmission disc 20 synchronously drives the annular shell 31 to rotate via multiple connecting rods 23. Since the first brush strip 32 contacts the outer wall of the annular shell 31, it can quickly clean the scale generated on the outer wall of the permeate membrane module 12 during rotation, avoiding the accumulation of scale from affecting the performance of the equipment. Cleaning fluid is injected into the filter cartridge 11 according to actual cleaning needs.

[0034] Further reference Figure 5 There are several annular shells 31 distributed at equal intervals, and connecting plates 33 are distributed in a ring between the annular shells 31.

[0035] In a further embodiment, the cleaning fluid injected inside the filter cartridge 11 is distributed among multiple annular shells 31 at equal intervals. The cleaning fluid can easily enter through the annular shells 31 and directly contact the outer wall of the permeate membrane assembly 12, improving the uniformity and efficiency of cleaning. Combined with the rotation of the annular shells 31, the outer wall of the permeate membrane assembly 12 is quickly cleaned through the first brush strip 32. At the same time, the multi-segment annular shell 31 configuration can significantly reduce the weight of the overall cleaning assembly 30, lighten the burden on the equipment, and improve the stability of the equipment.

[0036] Further reference Figures 5-7 The top of the connecting plate 33 is provided with a wiping strip 34, which is attached to the inner wall of the filter cartridge 11. When the annular shell 31 rotates, the wiping strip 34 can remove the scale generated on the inner wall of the filter cartridge 11, realize the self-cleaning function, ensure the cleanliness of the inner wall of the filter cartridge 11, and also provide a clean working space for the permeate membrane module 12.

[0037] Example 2 (in conjunction with Example 1):

[0038] refer to Figure 5 A second brush bar 35 is provided below the connecting plate 33, and the second brush bar 35 is distributed between each annular shell 31.

[0039] In the above scheme, each annular shell 31 is spaced apart, and there are no brush strips covering the outer wall of the permeate membrane module 12 at the intervals. However, a second brush strip 35 is set below the connecting plate 33. The second brush strip 35 can compensate for the lack of brush strips at the intervals. In this way, by rotating the cleaning component 30, in conjunction with the cleaning of the first brush strip 32 and the second brush strip 35, it is possible to achieve full coverage of the outer wall of the permeate membrane module 12, ensuring that the brush strips perform effective cleaning. The clean permeate membrane module 12 can maintain its optimal filtration performance, thereby improving the filtration efficiency and stability of the entire system.

[0040] The specific implementation process of this utility model is as follows:

[0041] The motor 261 transmits power to the gearbox 26. With the transmission gear 25 and driven gear 22 meshing with each other, the transmission disk 20 is driven to rotate through gear transmission. When the transmission disk 20 rotates, the torque is transmitted to the cleaning component 30 through multiple connecting rods 23 to rotate, that is, the annular shell 31 rotates. When the annular shell 31 rotates, it can quickly clean the scale generated on the outer wall of the permeate membrane module 12 through the first brush strip 32. At the same time, the wiping strip 34 above the annular shell 31 can remove the scale generated on the inner wall of the filter cartridge 11, realizing the self-cleaning function and ensuring the cleanliness of the inner wall of the filter cartridge 11.

[0042] In conjunction with the cleaning of the first brush bar 32 and the second brush bar 35, the outer wall of the permeate membrane module 12 can be fully covered, ensuring effective cleaning. A clean permeate membrane module 12 maintains its optimal filtration performance, thereby improving the overall filtration efficiency and stability of the system.
