[0002] DTRO, or disc-tube reverse osmosis technology, was first proposed by PALL ROCHEM and successfully operated in Germany. It now accounts for at least 75% of the global market share of landfill leachate treatment. DTRO is a form of reverse osmosis that uses pressure to make water in the leachate pass through the reverse osmosis membrane, intercepting pollutant molecules larger than 1nm, including ammonia nitrogen, to achieve the purpose of sewage treatment. Because it solves the problems of roll-type reverse osmosis pollution and blockage, it is an efficient membrane treatment technology. At present, this technology has gradually been widely used in the fields of high-salinity water treatment and zero discharge of industrial waste water in China.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-5 The utility model provides a technical solution: a disc-tube reverse osmosis membrane assembly, including a center rod 1 and a membrane shell 2, two end covers 5 are fixedly connected to the surface of the center rod 1, a plurality of diaphragms 7 are fixedly connected to the surface of the center rod 1, a plurality of guide plates 6 are fixedly connected to the inner wall of the membrane shell 2, a concentrated liquid pipe 8 is connected to the surface of the end cover 5, a feed pipe 9 is connected to the surface of the end cover 5, a clean water pipe 10 is connected to the surface of the end cover 5, an auxiliary device 3 is provided on the surface of the membrane shell 2, and a sealing device 4 is provided on the surface of the membrane shell 2.

[0033] The specific arrangement and function of the auxiliary device 3 and the sealing device 4 will be described in detail below.

[0034] like Figure 1 - Figure 4As shown, the auxiliary device 3 includes two slide rails 302, and the two slide rails 302 are fixedly connected to the arc surface of the Mick. The surfaces of the two slide rails 302 are slidably connected to the sliding frame 303, and the surface of the sliding frame 303 is threadedly connected to the screw 304. The end of the screw 304 close to the membrane shell 2 is rotatably connected to the arc plate 306. The surface of the arc plate 306 is fixedly connected to two limit rods 305. The two limit rods 305 are slidably connected to the sliding frame 303. The surface of the sliding frame 303 is rotatably connected to two rotating rods 308. The surfaces of the two rotating rods 308 are fixedly connected to The auxiliary rod 310 has two magnets 312 fixedly connected to its surface, which can assist in limiting the docking direction between the two membrane shell 2 components when docking, so that the two membrane shells 2 will not be offset when installed, thereby improving the docking installation efficiency between the two and facilitating the rapid implementation of reverse osmosis work. The arc surface of the membrane shell 2 is fixedly connected with two limit plates 301, and the two limit plates 301 are in a "V" shape. The surfaces of the two rotating rods 308 are provided with rectangular holes 309, and the size of the rectangular holes 309 is the same as that of the limit plates 301. The size of the auxiliary device 306 is adapted, and by setting the limiting plate 301 and the rectangular hole 309, the rotating rod 308 can be limited so that the rotating rod 308 will not rotate when it is carried or not in use, thereby improving the convenience of using the auxiliary device 3. The inner wall of the arc plate 306 is glued with an anti-skid pad 307, and the anti-skid pad 307 is made of rubber. Since the anti-skid pad 307 is made of rubber, it can increase the friction between the membrane shell 2 and will not cause damage to the membrane shell 2 when pressed. The surface of the auxiliary rod 310 is rotatably connected with a rotating wheel 311, and the rotating wheel 311 is connected to the surface of the membrane shell 2. The surface contact can improve the smoothness of the installation and movement of the membrane shell 2, and thus facilitate the connection and installation between the two membrane shells 2. The two magnets 312 are both trapezoidal. The surface of the auxiliary rod 310 is fixedly connected to the external plate 313, and the surface of the external plate 313 is rotatably connected to the rotating block 314. The surface of the rotating block 314 has a chamfered surface. Since the surface of the rotating block 314 has a chamfered surface, when it contacts the inclined surface of the magnet 312, the connection relationship between the two magnets 312 can be separated, and then the two auxiliary rods 310 are disconnected, which facilitates the use of the auxiliary rod 310.

[0035] like Figure 2 and Figure 4 as well as Figure 5As shown, the sealing device 4 includes two mounting plates 41, and the two mounting plates 41 are fixedly connected to the arc surface of the membrane shell 2. The surfaces of the two mounting plates 41 are slidably connected with plug rods 47, and the end of the plug rod 47 away from the membrane shell 2 is fixedly connected with a mounting disk 43, and the mounting disk 43 is respectively slidably connected to the concentration tank, the feed pipe 9, the clean water pipe 10 and the center rod 1, and the surface of the mounting disk 43 is glued with a sealing gasket 44, and the sealing gasket 44 is respectively slidably connected to the concentration tank, the feed pipe 9, the clean water pipe 10 and the center rod 1, and can be sealed at the pipeline connection between the two membrane shells 2, so that the pipeline will not leak when it is used for conveying materials, which facilitates the reverse osmosis work and increases the reverse osmosis effect when the reverse osmosis component is used. They are all fixedly connected with an extension plate 42, and a magic mother patch 46 is glued on the surface of the extension plate 42. A magic sub-patch 45 is glued on one end of the insertion rod 47 close to the extension plate 42. The magic sub-patch 45 and the magic mother patch 46 are conveniently adhered to each other, so that the convenience of using the sealing device 4 can be improved, so that the staff does not need to further support the mounting plate 43 when docking the membrane shell 2, thereby increasing the convenience of using the sealing gasket 44. Four tapered rods 48 are fixedly connected to the surface of the mounting plate 43, and the four tapered rods 48 are all in a "T" shape. Since one end of the tapered rod 48 is in a diamond shape, when the sealing gasket 44 is glued and installed, it can be inserted for installation, and when the gluing effect is reduced, the sealing gasket 44 will not fall off directly, thereby increasing the sealing effect of the sealing device 4.

[0036] Working principle: When performing reverse osmosis work, multiple membrane shell 2 components are connected. At this time, the screw 304 can be rotated in the opposite direction. There is a round hole at one end of the screw 304. The staff can easily use tools to drive the screw 304 to rotate, and then the arc plate 306 is separated from the surface of the membrane shell 2. At this time, the sliding frame 303 is separated from the limit. The staff presses the limit plate 301 to make the limit plate 301 separate from the rectangular groove position, and then separate from the limit on the rotating rod 308. At this time, the rotating rod 308 can be rotated toward the installation position of the membrane shell 2, and the two auxiliary rods 310 can be rotated together. There is a magnet 312 on the surface of the auxiliary rod 310, and the magnet 312 can make the two The two auxiliary rods 310 are tightly connected together, which can drive the sliding frame 303 to slide downward. When sliding to the bottom position, the staff can rotate the screw 304, and the screw 304 can drive the arc plate 306 to slide in the direction of the membrane shell 2, and then press against the surface of the membrane shell 2 to complete the limitation of the sliding frame 303, and the arc plate 306 is provided with an anti-skid pad 307 in the direction close to the membrane shell 2. Since the anti-skid pad 307 is made of rubber material, it can increase the friction between the membrane shell 2 and will not cause damage to the membrane shell 2 when pressing. Further, another membrane shell 2 can be placed in the middle of the two auxiliary rods 310 for docking, and there is an anti-skid pad 307 on the arc surface of the auxiliary rod 310. The rotating wheel 311 is provided, and the rotating wheel 311 contacts with the surface of the membrane shell 2, which can improve the smoothness of the membrane shell 2 during installation and movement, thereby facilitating the connection and installation between the two membrane shells 2. After the two membrane shells 2 are docked and installed, the staff can rotate the rotating block 314. Since the surface of the rotating block 314 is provided with a chamfered surface, when it contacts with the inclined surface of the magnet 312, the connection relationship between the two magnets 312 can be separated, and then the two auxiliary rods 310 are disconnected, which facilitates the use of the auxiliary rod 310. The screw rod 304 is rotated in the opposite direction, and the arc plate 306 is disengaged from the pressure, and then the rotating rod 308 can be rotated to rotate the rotating rod 308 in the direction of the limit plate 301, so that the limit The plate 301 is slidably connected to the rectangular hole 309, and then the screw 304 can be rotated to make the arc plate 306 abut against the surface of the membrane shell 2 to complete the limiting of the rotating rod 308. By setting the limiting plate 301 and the rectangular hole 309, the rotating rod 308 can be limited so that the rotating rod 308 will not rotate when being carried or not in use, thereby improving the convenience of using the auxiliary device 3. By setting the auxiliary device 3, when the two membrane shell 2 components are docked, the docking direction between the two can be limited to assist, so that the two membrane shells 2 will not be offset during installation, thereby improving the docking installation efficiency between the two and facilitating the rapid progress of reverse osmosis work.

[0037] When the two membrane shells 2 are docked, the plug rod 47 can be slidably connected to the mounting plate 41, and then the mounting plate 43 is docked to one end of the membrane shell 2, and a sealing gasket 44 is glued on the surface of the membrane shell 2, which can seal the connection between the concentration pipeline, the feed pipe 9 and the clean water pipe 10 between the two membrane shells 2 without leakage. When the plug rod 47 is installed, the magic sticker 45 at one end of the plug rod 47 can be glued to the magic mother body, so that the staff does not need to further support the mounting plate 43 when docking the membrane shells 2, and the sealing gasket 4 is increased. 4 is convenient to use, and a tapered rod 48 is connected to the surface of the mounting plate 43. Since one end of the tapered rod 48 is rhombus-shaped, it can be inserted for installation when the sealing gasket 44 is glued and installed, and when the gluing effect is reduced, the sealing gasket 44 will not fall directly, thereby increasing the sealing effect of the sealing device 4. By setting the sealing device 4, the pipeline connection between the two membrane shells 2 can be sealed, so that the pipeline will not leak when it is used for material transportation, which facilitates the reverse osmosis work and increases the reverse osmosis effect when the reverse osmosis component is used.
