Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis membranes, in particular to a reverse osmosis membrane element roll structure. Background Art

[0002] The reverse osmosis membrane element's roll-to-roll mechanism involves stacking and winding reverse osmosis membrane elements around a central tube, forming a spiral structure. This structure allows water molecules to pass smoothly through the membrane pores under pressure, while salt and other impurities are trapped on the outside of the membrane, thereby achieving water purification. The basic structure of a reverse osmosis membrane element consists of a multi-layer composite material: a polyester non-woven fabric at the bottom for support and strength; a cyclonic support layer in the middle for increased mechanical strength; and an ultra-thin selective permeable layer at the top made of cross-linked aromatic polyamide, ensuring efficient water passage and salt rejection. During the roll-to-roll process, water enters the end face of the reverse osmosis membrane element, flows through the surface of the membrane separation layer, and the product water seeps through the membrane surface into the product channel, then spirals into the center of the membrane element, ultimately collecting in the central tube. Concentrated water flows out the other end and undergoes a series of desalination processes to produce purified water.

[0003] The reverse osmosis membrane roll device, with China's authorized announcement number CN 213699484 U, eliminates manual gluing by coordinating a moving component with a gluing component. Laser light locates the membrane placement, accurately positioning the gluing position to avoid glue leakage during trimming. A rotating seat is used to rotate the center tube, allowing the membrane to be rolled onto it, reducing labor costs and improving efficiency.

[0004] However, this patent still has certain shortcomings when in use. When the existing roll membrane structure is in use, the roll membrane core barrel is generally a fixed structure fixed with screws. When the reverse osmosis membrane outside the roll membrane core barrel is used up, a new roll membrane core barrel needs to be replaced. When replacing, the screws must generally be unscrewed first, and the new roll membrane core barrel must be replaced. Then the screws must be tightened again. The process is very laborious and inconvenient to operate, and the efficiency is low. In addition, the reverse osmosis membrane outside the roll membrane core barrel needs to be cut at the edge of the membrane body halfway after the roll membrane is completed. Since the traction force will be suddenly lost after cutting, it is easy to cause the outer edge of the membrane body to loosen, which is inconvenient to continue using it next time. Moreover, when the membrane body becomes loose during the roll membrane process, the membrane body is generally adjusted manually, and the adjustment process is very time-consuming and has poor practicality.

[0030] In this embodiment, Figure 1 、 Figure 4 and Figure 5 As shown, the tensioning assembly 3 includes a first connecting plate 301 and a second connecting plate 302 fixedly connected to the side surfaces of the first fixed plate 201 and the second fixed plate 202, respectively. The side surfaces of the first connecting plate 301 and the second connecting plate 302 are rotatably connected to the first rotating plate 303 and the second rotating plate 304, respectively. The side surface of the first rotating plate 303 is fixedly connected to the second rotating plate 304 through a fixing rod 305. The outer portion of the fixing rod 305 is rotatably connected to a roller sleeve 306. The side surface of the first rotating plate 303 passes through the first connecting plate 301. The first rotating plate 30 3 is fixedly connected to the side of the adjusting block 307, and an adjusting button 308 is provided on the side of the adjusting block 307. The side of the first connecting plate 301 is fixedly connected to the moving cavity 309, and a second spring 310 is provided in the moving cavity 309. One end of the second spring 310 is elastically connected to the inner wall of the moving cavity 309, and the other end of the second spring 310 is elastically connected to a clamping block 312. A second damping rod 311 is provided inside the second spring 310, and the clamping block 312 is plugged into the clamping slot on the outside of the adjusting block 307. A push block 313 is fixedly connected to the side of the clamping block 312.

[0031] The tensioning assembly 3 is provided to realize the tensioning of the film body 5, and reduce the occurrence of folding caused by the relaxation of the film body 5 during the film rolling process. When the film rolling process is fast, resulting in the relaxation of the outer layer of the film body 5, the pushing block 313 is pushed along the inside of the moving cavity 309, and the pushing block 313 drives the card block 312 to move until the card block 312 and the card slot outside the adjusting block 307 no longer abut each other. Then, the adjusting knob 308 is turned to rotate the adjusting block 307. Since the side surface of the adjusting block 307 and the first rotating plate 308 are in contact with each other, the adjusting block 307 is rotated. 3 are fixedly connected. When the first rotating plate 303 rotates, the fixing rod 305 and the second rotating plate 304 are driven to rotate, thereby tensioning the film body 5 located between the two roller sleeves 306, so that the slack part of the film body 5 is tightened, and then the pushing block 313 is released. The adjusting block 307 is reset under the action of the rebound of the second spring 310 and abuts against the card slot outside the adjusting block 307 again, thereby fixing the adjusting block 307, avoiding folding caused by the slackness of the film during winding, and ensuring that the film winding process can be carried out stably.

[0032] The working process of the utility model: When the reverse osmosis membrane element roll membrane structure designed by the present invention is in operation, when the membrane body 5 and the roll 6 need to be installed, the membrane body 5 and the roll 6 are first placed on the top of the support block 409, and then the mounting blocks 208 and the abutment plates 207 on both sides are moved in opposite directions, and then the two mounting blocks 208 are aligned with the mounting grooves 7 on both sides of the roll 6 and installed. After the installation is completed, the first spring 205 is reset under the action of rebound, and at this time the mounting blocks 208 and The abutment plate 207 is respectively clamped with the side surface of the winding drum 6 and the inside of the mounting groove 7, thereby fixing the film body 5 and the winding drum 6. Later, when the film is rolled up, the film output speed is controlled by controlling the speed of the driving motor 210. At the same time, the support block 409 limits the support of the tail end of the film body 5, and the position of the support block 409 can change with the thickness of the film body 5. When the film body 5 gradually becomes thinner, the squeezing force of the film body 5 on the support block 409 is weakened. At this time, under the action of the fourth spring 408, the slide The block 402 moves to the middle position, and the rotating rod 406 rotates, supporting the supporting block 409 upward, so that the supporting block 409 and the outer part of the film body 5 are again fitted together. When the film rolling process is fast, causing the outer layer of the film body 5 to become loose, the pushing block 313 is pushed along the inside of the moving cavity 309, and the pushing block 313 drives the card block 312 to move until the card block 312 and the card slot outside the adjusting block 307 no longer abut each other. Then, by turning the adjusting knob 308, the adjusting block 307 is rotated, and the adjusting block 307 is rotated. The side of the adjusting block 307 is fixedly connected to the first rotating plate 303. When the first rotating plate 303 rotates, it drives the fixing rod 305 and the second rotating plate 304 to rotate, thereby tensioning the membrane body 5 located between the two roller sleeves 306, so that the slack part of the membrane body 5 is tightened, and then the pushing block 313 is released. The adjusting block 307 is reset under the action of the rebound of the second spring 310, and again abuts against the card slot outside the adjusting block 307, thereby fixing the adjusting block 307.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
