The roll-type membrane 2 comprises a central water production pipe 21 arranged in the installation barrel 11, a filtering membrane 22 wound on the central water production pipe 21 and an adhesive tape 23 wound on the central water production pipe 21, and a plurality of water seepage holes 211 communicated to the inner hole of the central water production pipe 21 are formed in the outer wall of the central water production pipe 21. In order to increase the flow of raw water in the filtering membrane 22 and improve the desalination rate and water yield, a plurality of the roll-type membranes 2 may be arranged side by side along the length direction of the installation cylinder 11, and the present application takes three roll-type membranes 2 as an example for explanation. Wherein, one end of the roll type membrane 2 positioned at the two ends is positioned in the water inlet cavity 16 and communicated with the raw water inlet pipe 13, and the other end is positioned in the water outlet cavity 17 and communicated with the concentrated water outlet pipe 14; one end of the central water production pipe 21 close to the raw water inlet pipe 13 is sealed, and the other end of the central water production pipe 21 is communicated with the pure water outlet pipe 15. When the water purifier is used, raw water to be filtered flows into the installation barrel 11 from the raw water inlet pipe 13 and is located in the water inlet cavity 16, the raw water located in the water inlet cavity 16 flows into the filtering membrane 22 from one end face of the filtering membrane 22, one part of water reaches the central water production pipe 21 from the water seepage hole 211 through the filtering of the filtering membrane 22 to become pure water and finally flows out from the pure water outlet pipe 15, and the other part of water reaches the water outlet cavity 17 at the other end of the rolled membrane 2 along the length direction of the filtering membrane 22 and finally flows out from the concentrated water outlet pipe 14.
Referring to fig. 2, a first connection module 3 is disposed between two adjacent rolled membranes 2, and in particular, the first connection module 3 is connected to a central water production pipe 21 of two adjacent rolled membranes 2. A second connecting assembly 4 is arranged between a central water producing pipe 21 close to the pure water outlet pipe 15 and the pure water outlet pipe 15, and the communication between the central water producing pipe 21 and the pure water outlet pipe 15 can be realized through the second connecting assembly 4, so that the pure water filtered out from the central water producing pipe 21 reaches the pure water outlet pipe 15 through the second connecting assembly 4 and is discharged. The second connecting assembly 4 comprises a second connecting cylinder 41, and two ends of the second connecting cylinder 41 are respectively in inserting fit with the central water production pipe 21 and the pure water outlet pipe 15. The second connecting component 4 and the first connecting component 3 have the same structure, and the difference is only the difference of the installation position, and the first connecting component 3 is taken as an example for explanation in the present application.
Referring to fig. 3 and 4, the first connection assembly 3 includes a first connection barrel 31, two ends of the first connection barrel 31 are respectively in insertion fit with the two central water production pipes 21, and the central water production pipe 21 and the first connection barrel 31 are in interference fit. The adjacent two central water production tubes 21 can be connected by inserting the two central water production tubes 21 into the first connecting cylinders 31 from both ends of the first connecting cylinders 31, respectively, so that the filtered pure water can pass from one central water production tube 21 to the other central water production tube 21 through the first connecting cylinder 31, and finally flow out from the pure water outlet tube 15 (refer to fig. 2). The raw water is filtered by the filtering membrane 22 to become concentrated water, and the concentrated water reaches the other end of the filtering membrane 22 and finally flows out from the concentrated water outlet pipe 14 (see fig. 2). The raw water is sequentially filtered by the three filtering membranes 22, so that the desalination rate and the water yield of the raw water are greatly increased.
In order to prevent pure water in the central water production pipe 21 from flowing out between the central water production pipe 21 and the first connecting cylinder 31, or concentrated water in the installation cylinder 11 flows to the central water production pipe 21 from the connection part of the central water production pipe 21 and the first connecting cylinder 31, so that the pure water and the concentrated water are mixed. A first sealing ring 32 is arranged between the central product water pipe 21 and the first connecting cylinder 31.
Referring to fig. 4, two first sealing rings 32 are arranged between each central water production pipe 21 and the first connecting cylinder 31, the two first sealing rings 32 are arranged at intervals along the axial direction of the first connecting cylinder 31, and the arrangement of the two first sealing rings 32 enables the sealing between the first connecting cylinder 31 and the central water production pipe 21 to be tighter.
The first sealing ring 32 can be an O-shaped ring, and has the advantages of simple structure, reliable function and lower installation requirement. The inner wall of the first connecting cylinder 31 is provided with the placing grooves 33 along the length direction thereof at intervals for the first packing 32 to be inserted, the position of the first packing 32 in the connecting cylinder 31 can be fixed by inserting the first packing 32 into the placing grooves 33, and then the central water producing pipe 21 of the two rolled membranes 2 is directly inserted into the first connecting cylinder 31 from both ends of the first connecting cylinder 31, the first packing 32 is positioned between the first connecting cylinder 31 and the central water producing pipe 21, thereby sealing the first connecting cylinder 31 and the central water producing pipe 21.
Referring to fig. 4 and 5, the central water production pipe 21 is released from the first connecting cylinder 31 in order to prevent the central water production pipe 21 from sliding in the first connecting cylinder 31 by an external force. A first rib 34 with a hemispherical cross section is fixedly connected to the inner wall of the first connecting cylinder 31, a second rib 35 with a hemispherical cross section is fixedly connected to the outer wall of each first central water producing pipe 21, and when the central water producing pipe 21 is inserted into the first connecting cylinder 31, the second rib 35 also extrudes the first rib 34 and slides to the side of the first rib 34 facing the inside of the first connecting cylinder 31. The second rib 35 is fixed in position in the first connecting cylinder 31 by the first rib 34, and the central water producing pipe 21 is prevented from sliding out of the first connecting cylinder 31 under the action of external force.
And a sealing sleeve 36 is further arranged on the first connecting cylinder 31 and the central water production pipe 21, the length of the sealing sleeve 36 is greater than that of the first connecting cylinder 31, and the sealing sleeve 36 can simultaneously seal the joints of the two ends of the first connecting cylinder 31 and the central water production pipe 21, so that the sealing performance of the first connecting cylinder 31 and the central water production pipe 21 is further improved. In a normal state, the sealing sleeve 36 is sleeved on the first connecting cylinder 31, two ends of the sealing sleeve 36 are folded outwards and overlapped on the sealing sleeve 36 on the first connecting cylinder 31, after the central water production pipe 21 is inserted into the first connecting cylinder 31, two ends of the sealing sleeve 36 are directly operated to be folded towards the central water production pipe 21, the sealing sleeve 36 can cover and seal the joint of the first connecting cylinder 31 and the central water production pipe 21, and sealing efficiency is better.
Referring to fig. 1 and 6, in order to avoid that when water in the water inlet chamber 16 flows from the inside of the rolled membrane 2 to the water outlet chamber 17, part of the water flows between the adhesive tape 23 and the mounting cylinder 11 without being filtered by the rolled membrane 2, thereby reducing the water production efficiency of the rolled membrane 2. Two end plate sealing members 5 are sleeved on each central water production pipe 21, and the two end plate sealing members 5 are respectively positioned at two ends of each filtering membrane 22.
Referring to fig. 6 and 7, the end plate seal 5 includes an inner ring 51 fitted over the central water production tube 21, an outer ring 52 slidably coupled within the mounting tube 11, and a connecting rod 53 secured between the inner ring 51 and the outer ring 52. Wherein the outer ring 52 and the inner ring 51 are concentrically arranged, the end surface of the outer ring 52 is abutted against the filtering membrane 22, so that the space between the filtering membrane 22 and the mounting cylinder 11 can be blocked, and water is prevented from reaching the space between the filtering membrane 22 and the inner wall of the mounting cylinder 11. Meanwhile, a second sealing ring 54 is arranged between the outer ring 52 and the mounting cylinder 11, and the second sealing ring 54 can seal between the outer ring 52 and the mounting cylinder 11, so that water is prevented from flowing between the adhesive tape 23 and the mounting cylinder 11 from between the outer ring 52 and the mounting cylinder 11.
Referring to fig. 7, an annular receiving groove 55 is formed in an outer wall of the outer ring 52, the second sealing ring 54 is mounted in the receiving groove 55, and the position of the second sealing ring 54 on the outer ring 52 can be fixed through the receiving groove 55, so that the normal sealing operation between the outer ring 52 and the mounting cylinder 11 is prevented from being affected by the second sealing ring 54 and the outer ring 52 being disengaged from each other under the action of an external force.
The second sealing ring 54 may be a lip-shaped sealing ring, for example: u-shaped rings, Y-shaped rings, V-shaped rings and the like. When the second sealing ring 54 is installed in the accommodating groove 55, the opening of the second sealing ring 54 faces to the side away from the filtering membrane 22, and the inner side of the second sealing ring 54 is located in the accommodating groove 55, and the outer side thereof extends out of the accommodating groove 55 and abuts against the inner wall of the installation cylinder 11 under the action of the self-elastic force, so that the space between the outer ring 52 and the installation cylinder 11 is sealed. Due to the adoption of the lip-shaped sealing ring, when the roll-type membrane 2 sinks under the influence of gravity after being used for a period of time, and the axis of the roll-type membrane 2 is located on the lower side of the axis of the installation barrel 11, the part, located on the lower side of the roll-type membrane 2, of the second sealing ring 54 is extruded between the roll-type membrane 2 and the inner wall of the installation barrel 11, the part, located on the upper side of the roll-type membrane 2, of the second sealing ring 54 is always abutted to the inner wall of the installation barrel 11 under the action of self elasticity, and compared with a common O-shaped ring, the self-adaptive capacity of the roll-type membrane is stronger, and the sealing is tighter. When water impacts one end of the rolled membrane 2, the water directly impacts the opening of the second sealing ring 54, and the impact force of the water is larger, the sealing of the second sealing ring 54 is tighter, and the sealing effect is better.
Referring to fig. 6, the inner ring 51 is a sliding fit with the central product water pipe 21, and in particular, the inner ring 51 is an interference fit with the central product water pipe 21. When the water pipe is installed, the inner ring 51 is directly sleeved on the central water production pipe 21 until one end of the inner ring 51 facing the filtering membrane 22 is abutted against the filtering membrane 22, so that the position of the inner ring 51 on the central water production pipe 21 is fixed through interference fit.
Wherein, in order to increase the friction between the inner ring 51 and the central water production pipe 21, anti-slip lines 56 are processed on the outer wall of the central water production pipe 21, and the anti-slip lines 56 are positioned at the intersection of the inner ring 51 and the filter membrane 22. When the water pipe is installed, the inner ring 51 is directly sleeved on the central water production pipe 21, then the inner ring 51 is operated to slide towards the direction of the filter membrane 22 until the inner ring 51 slides to the anti-skid grains 56 and one end of the inner ring 51 facing the filter membrane 22 is abutted against the filter membrane 22, so that the position of the inner ring 51 on the central water production pipe 21 is fixed through the anti-skid grains 56.
Referring to fig. 2 and 3, as the raw water passes through the filtering membrane 22, salt contained in the raw water is left on the filtering membrane 22 to increase the weight of the filtering membrane 22, and the weight of each roll type membrane 2 is not uniform due to the non-uniform amount of salt remained on each filtering membrane 22. The sinking amplitude of the roll-type membrane 2 with more residual salt is larger under the action of the self gravity, the sinking amplitude of the roll-type membrane 2 with less residual salt is smaller under the action of the self gravity, and the axis of each roll-type membrane 2 is staggered up and down, so that the connection of the joints of two adjacent roll-type membranes 2 is not tight. Therefore, a baffle ring 6 for supporting the rolled membranes 2 is arranged between two adjacent rolled membranes 2, so that all the rolled membranes 2 are in the same axial position, and the baffle ring 6 can also be simultaneously placed between the rolled membranes 2 at two ends and the two end covers 12, i.e. the water inlet cavity 16 and the water outlet cavity 17 are formed, thereby fixing the positions of the rolled membranes 2 in the installation cylinder 11.
Referring to fig. 2 and 8, the barrier ring 6 comprises a first ring 61 slidably connected in the mounting tube 11, a second ring 62 slidably connected in the mounting tube 11, and a telescopic rod 63 disposed between the first ring 61 and the second ring 62. The shape and size of the first ring 61 and the second ring 62 are the same, the telescopic rods 63 are arranged in a plurality of equal intervals along the circumferential direction of the first ring 61 and the second ring 62, and the application takes the example that the telescopic rods 63 are provided with four rings. When the baffle ring 6 is installed in the installation barrel 11, one end of the first ring 61 away from the telescopic rod 63 and one end of the second ring 62 away from the telescopic rod 63 respectively abut against the end plate sealing members 5 of the two adjacent roll-type membranes 2, so that the relative positions of the two adjacent roll-type membranes 2 are supported and fixed, and the situation that when the two central water production pipes 21 slide in the first connecting barrel 31 under the action of external force, the central water production pipe 21 and the first connecting barrel 31 are not tightly sealed is avoided.
