The disassembly and assembly process is simple and efficient.

Description

Technical Field

[0001] This utility model relates to the field of filter membrane module technology, specifically to a DTNF membrane module. Background Technology

[0002] DTNF membrane (Disc Tube NF) refers to a nanofiltration membrane with a pore size of 1-2 nm. It is a functional semi-permeable membrane that allows solvent molecules or certain low molecular weight solutes or low valence ions to pass through. It is suitable for the treatment of wastewater with high turbidity and high sand content. It has the characteristics of high pressure resistance and high rejection rate and is mainly used in the field of water treatment under harsh influent conditions.

[0003] DTNF membrane modules are mostly fixed to the equipment with bolts. During the use of DTNF membrane modules, disassembly, cleaning and other maintenance work are often required. At this time, the bolts need to be disassembled and reassembled, which is cumbersome and leads to low maintenance efficiency. Utility Model Content

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] like Figures 1-5 As shown, this utility model provides a DTNF membrane module, including a base 1, a convenient disassembly and assembly mechanism 2 on the top of the base 1, and a coarse filter protection mechanism 3 on the convenient disassembly and assembly mechanism 2.

[0026] The convenient disassembly and assembly mechanism 2 includes a first side plate 21 and a second side plate 23. The second side plate 23 is fixedly installed on the top of the base 1. A support column 24 is fixedly installed on the left side of the second side plate 23. A sleeve 25 is slidably connected to the outer wall of the support column 24. An elastic element 26 is fixedly installed on the right side of the sleeve 25. The elastic element 26 is fixedly installed on the left side of the second side plate 23. When disassembling and maintaining the filter cartridge 28, push the sleeve 25 to the right from the handle 27, which will cause the filter cartridge 28 to move out of the sleeve 25. Then pull out the fitting tube 281 from the inside of the protruding tube 22, thus realizing the function of disassembling the filter cartridge 28. Conversely, first push the sleeve 25 to the right, then insert the fitting tube 281 into the protruding tube 22, and then release the sleeve 25. Through the elastic force of the elastic element 26, the sleeve 25 is driven to be inserted into the right end of the filter cartridge 28, thus completing the installation work.

[0027] Furthermore, such as Figure 2 As shown, a water outlet pipe 11 is fixedly connected to the left side of the first side plate 21, the first side plate 21 is fixedly installed on the top of the base 1, and a protruding pipe 22 is fixedly connected to the right side of the first side plate 21. When in use, the treated water can be drawn out from the water outlet pipe 11.

[0028] Furthermore, such as Figure 2 As shown, a handle 27 is fixedly installed on the outer wall of the sleeve 25, and a filter cartridge 28 is movably inserted into the inner cavity of the sleeve 25. The design of the handle 27 makes it convenient for the user to push the sleeve 25.

[0029] Furthermore, such as Figure 3As shown, a fitting tube 281 is fixedly connected to the left side of the filter cartridge 28. A rubber ring is fixedly connected to the outer wall of the fitting tube 281. The fitting tube 281 is movably inserted into the inside of the protruding tube 22. A DTNF membrane 282 is fixedly connected to the side of the inner wall of the filter cartridge 28. The rubber ring can seal the connection between the fitting tube 281 and the protruding tube 22. The DTNF membrane 282 is used to filter and purify water. After the filter cartridge 28 is removed, clean water can be injected from the fitting tube 281 at the top to backwash the DTNF membrane 282.

[0030] Furthermore, such as Figure 4 As shown, the coarse filter protection mechanism 3 includes a square tube 31. A first valve 32 is fixedly connected to the left side of the square tube 31, and a second valve 33 is fixedly connected to the right side of the square tube 31. By controlling the first valve 32 and the second valve 33 to close, the stainless steel filter cartridge 36 can be disassembled and cleaned.

[0031] Furthermore, such as Figure 1 As shown, valve 33 is fixedly connected to the left side of side plate 21, and inlet pipe 12 is fixedly connected to the left side of valve 32. Support block 34 is fixedly installed on the inner wall of square tube 31. When in use, the water to be treated can be introduced from inlet pipe 12.

[0032] Furthermore, such as Figure 4 As shown, a connector plate 35 is movably inserted into the bottom of the square tube 31, and a stainless steel filter cartridge 36 located in the inner cavity of the square tube 31 is fixedly installed on the top of the connector plate 35. The stainless steel filter cartridge 36 is used to pre-filter the water entering the filter cartridge 28, filter out larger particulate impurities, and reduce the load of subsequent DTNF membrane 282 filtration. Through the design of two stainless steel filter cartridges 36, four coarse filtrations can be implemented.

[0033] Furthermore, such as Figure 4 , Figure 5 As shown, a protruding column 311 is fixedly installed at the bottom of the square tube 31. A limiting block 312 is rotatably connected to the outer wall of the protruding column 311. A locking bolt 313 is threadedly connected to the outer wall of the limiting block 312. The threaded end of the locking bolt 313 is in contact with the outer wall of the protruding column 311. In the initial state, the limiting block 312 is in contact with the bottom of the plug-in plate 35. If the stainless steel filter cartridge 36 needs to be disassembled and cleaned, the locking bolt 313 is loosened and the limiting block 312 is rotated out from the bottom of the plug-in plate 35. Then the plug-in plate 35 can be pulled down to take out the stainless steel filter cartridge 36, so as to facilitate the cleaning of the stainless steel filter cartridge 36.

[0034] The working principle of this DTNF membrane module will be explained in detail below.

[0035] like Figures 1-5As shown, during use, the water to be treated is introduced through the inlet pipe 12. The stainless steel filter cartridge 36 pre-filters the water entering the filter cartridge 28, and then the water is purified by the DTNF membrane 282. The treated water can be led out through the outlet pipe 11. If the stainless steel filter cartridge 36 needs to be disassembled and cleaned, close valve 32 and valve 33, loosen the locking bolt 313, and then rotate the limit block 312 out from the bottom of the plug plate 35. The plug plate 35 can then be pulled down to bring out the stainless steel filter cartridge 36, making it easier to clean the stainless steel filter cartridge. When cleaning the cartridge 36 and disassembling and maintaining the filter cartridge 28, push the sleeve 25 to the right from the handle 27. This will cause the filter cartridge 28 to move out of the sleeve 25. Then, pull the fitting tube 281 out of the protruding tube 22. This completes the disassembly of the filter cartridge 28. When reinstalling, first push the sleeve 25 to the right, then insert the fitting tube 281 into the protruding tube 22. Then, release the sleeve 25. Through the elastic force of the elastic element 26, the sleeve 25 will be inserted into the right end of the filter cartridge 28. This completes the installation.

[0036] It should be noted that, in the description of this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joint" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.
