Description

Technical Field

[0001] The utility model relates to the technical field of spiral membranes, and specifically relates to a novel spiral membrane. Background Technique

[0002] The principle of the spiral membrane is mainly to use micropores to isolate solutes and solvents, and to achieve water purification and concentration by applying high pressure. Spiral membranes, including spiral reverse osmosis membranes and spiral ultrafiltration membranes, all achieve water filtration and purification through specific membrane structures. These membranes are usually composed of multiple thin film layers and have micropore structures of specific sizes. These micropores can selectively filter out macromolecular solutes in the solution, such as bacteria, viruses, and other impurities, as needed, while allowing water molecules and dissolved small molecule substances to pass through.

[0003] Spiral membranes are widely used in water treatment and desalination processes in industries such as pharmaceuticals, beverages, chemicals, and food. At the same time, the ultrafiltration technology contained in the membrane process is the most critical process in the production process of sodium D-mannuronate raw materials, directly determining the quality and yield of the final product. The spiral membrane is the core production process in the production process.

[0004] For example, in a novel spiral membrane housing structure with the application number 202323188910.0, the sealing ring is integrally connected with the inner membrane frame by using an outer convex block. At the same time, the inner card on the inner membrane frame can be clamped inside the sealing ring to prevent water from flowing and leaking between the membrane housing body and the sealing ring, improving the sealing strength of the membrane housing body. However, there are still certain defects in its device;

[0005] When it is necessary to repair or replace the spiral membrane, it is necessary to separate the spiral membrane from its housing. Generally, the circular surface of the spiral membrane is flush with the circular surface of its housing, making it inconvenient to pull out the spiral membrane from the housing.

[0006] Therefore, we propose a novel spiral membrane to facilitate solving the problems raised above. Content of the Utility Model

[0007] The purpose of the utility model is to provide a novel spiral membrane to solve the problem that when it is necessary to repair or replace the spiral membrane in the current market, it is necessary to separate the spiral membrane from its housing, and generally, the circular surface of the spiral membrane is flush with the circular surface of its housing, making it inconvenient to pull out the spiral membrane from the housing as mentioned in the above background technique.

[0008] To achieve the above object, the utility model provides the following technical solution: a novel spiral wound membrane, comprising a spiral wound membrane housing, a sealing cover and a pressing block. A fixing ring is installed on the spiral wound membrane housing, and a spiral wound membrane filter element is installed inside the spiral wound membrane housing. The sealing cover is installed above the spiral wound membrane housing. Built-in grooves are respectively formed on the left and right sides of the upper inner wall of the spiral wound membrane housing, and a connecting plate penetrates through the inside of the built-in grooves. Moreover, pressing blocks are installed on the opposite sides of the connecting plate. A movable plate is installed on the pressing block, and the movable plate is connected with the inner wall of the built-in groove through a telescopic spring. Thread grooves are formed on the outer sides of the connecting plates, and threaded rods are installed in the thread grooves. A placement groove is formed inside the sealing cover, a magnetic block is installed on the inner wall of the placement groove, and a hook is installed below the placement groove through a connecting rope.

[0009] Preferably, the sealing cover and the spiral wound membrane housing can form a sealed state after being connected, and a liquid inlet is installed above the sealing cover, and the liquid inlet is communicated with the spiral wound membrane housing.

[0010] With the above structural design, the stock solution is transported through the liquid inlet to the spiral wound membrane filter element inside the spiral wound membrane housing for concentration and filtration.

[0011] Preferably, positioning bolts are installed on the sealing cover, and there are six positioning bolts. The positioning bolts and the fixing ring form a threaded connection structure, and the positioning bolts are distributed in a circular structure.

[0012] With the above structural design, the sealing cover is fixed by a plurality of positioning bolts, thereby improving the stability and sealing effect of the sealing cover.

[0013] Preferably, the length of the pressing block is less than the length of the built-in groove, and the pressing block and the connecting plate are fixedly connected.

[0014] With the above structural design, when the pressing block is stressed, it can move left and right in the built-in groove, thereby realizing the extrusion of the spiral wound membrane filter element inside the spiral wound membrane housing through the pressing block.

[0015] Preferably, the telescopic spring and the movable plate are perpendicular to each other, and the connecting plate and the movable plate are perpendicular to each other. The connecting plate and the movable plate are fixedly connected, and the connecting plate and the spiral wound membrane housing form a sliding connection structure.

[0016] With the above structural design, when the connecting plate moves left and right under stress, it can move left and right along the spiral wound membrane housing, thereby making the connecting plate more stable when moving left and right and not deviating, so that the pressing block connected to the connecting plate is more stable when moving left and right.

[0017] Preferably, the central axis of the threaded rod coincides with the central axis of the thread groove, and a threaded structure connection is formed between the threaded rod and the thread groove. The outer ends of the threaded rod and the connecting plate are both designed in an arc structure.

[0018] With the above structural design, when it is necessary to disassemble the spiral wound membrane filter element, rotate the threaded rod to make the threaded rod move outwards along the thread groove, and then press the threaded rods on both sides of the spiral wound membrane housing. The threaded rod drives the connecting plate, the extrusion block and the movable plate to move inwards. At this time, the telescopic spring is in a stretched state, so that the extrusion block moves inwards to squeeze the spiral wound membrane filter element, creating a gap between the spiral wound membrane filter element and the spiral wound membrane housing, facilitating the extraction of the spiral wound membrane filter element and thus facilitating the disassembly of the spiral wound membrane filter element.

[0019] Preferably, the hook and the magnetic block can be mutually adsorbed, and there are two placement grooves, magnetic blocks, connecting ropes and hooks respectively.

[0020] With the above structural design, the two sides of the spiral wound membrane filter element can also be hooked by the hooks under the sealing cover, further improving the disassembly efficiency of the spiral wound membrane filter element. The hooks can be stored in the placement grooves through the adsorption of the magnetic blocks.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1-5, the present utility model provides a technical solution: a novel spiral wound membrane, including a spiral wound membrane housing 1, a fixing ring 2, a spiral wound membrane filter element 3, a sealing cover 4, a liquid inlet 5, positioning bolts 6, an internal groove 7, a connecting plate 8, a pressing block 9, a movable plate 10, a telescopic spring 11, a threaded groove 12, a threaded rod 13, a placement groove 14, a magnetic block 15, a connecting rope 16 and a hook 17. A fixing ring 2 is installed on the spiral wound membrane housing 1, and a spiral wound membrane filter element 3 is installed inside the spiral wound membrane housing 1. A sealing cover 4 is installed above the spiral wound membrane housing 1. After the sealing cover 4 is connected to the spiral wound membrane housing 1, a sealed state can be formed. And a liquid inlet 5 is installed above the sealing cover 4. The liquid inlet 5 is communicated with the spiral wound membrane housing 1. The stock solution is conveyed into the spiral wound membrane filter element 3 inside the spiral wound membrane housing 1 through the liquid inlet 5 for concentration filtration. Six positioning bolts 6 are installed on the sealing cover 4. The positioning bolts 6 form a threaded structure connection with the fixing ring 2, and the positioning bolts 6 are distributed in a circular structure. The sealing cover 4 is fixed by a plurality of positioning bolts 6, thereby improving the stability and sealing effect of the sealing cover 4. Internal grooves 7 are opened on the left and right sides of the upper inner wall of the spiral wound membrane housing 1. A connecting plate 8 penetrates through the inside of the internal groove 7. And a pressing block 9 is installed on the opposite side of the connecting plate 8. The length of the pressing block 9 is less than the length of the internal groove 7, and the pressing block 9 is fixedly connected to the connecting plate 8. When the pressing block 9 is stressed, it can move left and right in the internal groove 7, thereby realizing the extrusion of the spiral wound membrane filter element 3 inside the spiral wound membrane housing 1 through the pressing block 9. A movable plate 10 is installed on the pressing block 9. And the movable plate 10 is connected to the inner wall of the internal groove 7 through a telescopic spring 11. The telescopic spring 11 is perpendicular to the movable plate 10, and the connecting plate 8 is perpendicular to the movable plate 10. The connecting plate 8 is fixedly connected to the movable plate 10. The connecting plate 8 forms a sliding connection structure with the spiral wound membrane housing 1. When the connecting plate 8 moves left and right under stress, it can move left and right along the spiral wound membrane housing 1, thereby making the connecting plate 8 more stable when moving left and right and not deviating, so that the pressing block 9 connected to the connecting plate 8 is more stable when moving left and right.

[0032] The outer side of the connecting plate 8 is provided with a threaded groove 12, and a threaded rod 13 is installed in the threaded groove 12. The center line of the threaded rod 13 coincides with the center line of the threaded groove 12, and a threaded structure connection is formed between the threaded rod 13 and the threaded groove 12. The outer ends of the threaded rod 13 and the connecting plate 8 are both designed in an arc structure. When the spiral wound membrane filter element 3 needs to be disassembled, rotate the threaded rod 13 to make the threaded rod 13 move outwards along the threaded groove 12, and then press the threaded rods 13 on the left and right sides of the spiral wound membrane housing 1. The threaded rod 13 drives the connecting plate 8, the extrusion block 9 and the movable plate 10 to move inwards. At this time, the telescopic spring 11 is in a stretched state, so that the extrusion block 9 moves inwards to squeeze the spiral wound membrane filter element 3, creating a gap between the spiral wound membrane filter element 3 and the spiral wound membrane housing 1, facilitating the extraction of the spiral wound membrane filter element 3, and thus facilitating the disassembly of the spiral wound membrane filter element 3. A placement groove 14 is provided inside the sealing cover 4, and a magnetic block 15 is installed on the inner wall of the placement groove 14. And a hanging hook 17 is installed below the placement groove 14 through a connecting rope 16. The hanging hook 17 and the magnetic block 15 can adsorb each other. Both the placement groove 14, the magnetic block 15, the connecting rope 16 and the hanging hook 17 are provided with two. At the same time, the two sides of the spiral wound membrane filter element 3 can also be hooked by the hanging hook 17 below the sealing cover 4, thereby further improving the disassembly efficiency of the spiral wound membrane filter element 3. The hanging hook 17 can be stored in the placement groove 14 through the adsorption of the magnetic block 15.

[0033] Working principle: When using this new type of spiral wound membrane, first, install the sealing cover 4. Align the threaded hole on the sealing cover 4 with the fixed ring 2, and then move the sealing cover 4 downwards. The inner wall of the sealing cover 4 will squeeze the connecting plate 8 and the threaded rod 13, thereby driving the extrusion block 9 on the connecting plate 8 to move inwards. However, when the extrusion block 9 moves, it will not exceed the built-in groove 7. Then fix the sealing cover 4 with the positioning bolt 6.

[0034] When the spiral wound membrane filter element 3 needs to be disassembled, open the sealing cover 4, rotate the threaded rod 13 to make the threaded rod 13 move outwards along the threaded groove 12, and then press the threaded rods 13 on the left and right sides of the spiral wound membrane housing 1. The threaded rod 13 drives the connecting plate 8, the extrusion block 9 and the movable plate 10 to move inwards. At this time, the telescopic spring 11 is in a stretched state, so that the extrusion block 9 moves inwards to squeeze the spiral wound membrane filter element 3, creating a gap between the spiral wound membrane filter element 3 and the spiral wound membrane housing 1, facilitating the extraction of the spiral wound membrane filter element 3, and thus facilitating the disassembly of the spiral wound membrane filter element 3. At the same time, the two sides of the spiral wound membrane filter element 3 can also be hooked by the hanging hook 17 below the sealing cover 4, thereby further improving the disassembly efficiency of the spiral wound membrane filter element 3. After the disassembly is completed, the hanging hook 17 can be stored in the placement groove 14 through the adsorption of the magnetic block 15. Thus, a series of operations are completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0035] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
