Description

Technical Field

[0001] The utility model relates to the technical field of homogeneous membrane electrodialysis water distributors, in particular to a novel homogeneous membrane electrodialysis water distributor. Background Art

[0002] Dialysis refers to the process by which solutes in a solution pass through a semipermeable membrane. The driving force behind natural dialysis is the concentration difference between the two sides of the membrane. The process by which ions pass through a selective ion exchange membrane under the influence of a DC electric field is called electrodialysis. Electrodialysis technology is applicable to reclaimed water treatment in industries such as petroleum, electronics, pharmaceuticals, chemicals, thermal power generation, food, beer, beverages, printing and dyeing, and coatings. It is also used in specialized separation applications such as the concentration and purification of amino acids, oligoxylose, proteins, milk, betaine, and pharmaceutical intermediates.

[0003] A complete electrodialysis unit consists of clamping plates, electrode plates, leak-proof gaskets, membrane elements, and separators. The separators play important roles in support and water distribution, and the water distributor within the separators is a crucial component. The uniformity of water distribution and the degree of fouling and blockage significantly impact the equipment's treatment efficiency and service life.

[0004] Traditional water distributors are prone to fouling and clogging after prolonged use. When clogged, the water flow channel narrows, reducing water flow and impacting the electrodialysis process. This results in reduced treatment efficiency and an inability to meet production needs. Furthermore, conventional water distributors are welded directly between the distributor end face and the baffle end face, resulting in a small weld area and a high risk of detachment. Utility Model Content

[0005] The purpose of the present invention is to provide a novel homogeneous membrane electrodialysis water distributor to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new type of homogeneous membrane electrodialysis water distributor, comprising a main body, the front and back of the main body are provided with guide grooves, the front and back of the main body are provided with sealing wires, the side of the main body is provided with welding ears, the welding ears are welded with welding ear flash, the front and back of the main body are provided with cleaning components for cleaning the guide grooves, the cleaning components are composed of a cleaning part and a driven control part, the welding ears and the welding ear flash are welded by laser welding, under the action of the laser, the welding ear flash is integrated into the welding ear, connecting the main body and the partition as a whole, ensuring that the main body will not fall off during use.

[0007] Preferably, the cleaning part includes a slide rail, which is fixed on the surface of the main body, and the slide rail is slidably connected to the movable plate. The side of the movable plate close to the main body is penetrated by the scraper and is slidably connected to the scraper. A movable groove is provided on the side of the movable plate close to the main body, and a fixed plate is fixed on the inner side of the movable groove. A return spring is fixed on the side of the scraper close to the fixed plate, and the end of the return spring away from the scraper is fixed to the fixed plate. The scraper can be driven to move by pulling the movable plate, and the scraper interface cleans the inner side of the guide groove to avoid the guide groove from being blocked by dirt, which causes the guide groove to become narrower, the water flow rate to be reduced, and the normal progress of the electrodialysis process to be affected.

[0008] Preferably, a through hole is provided in the center of the scraper.

[0009] The cam is fixed on the side of the fixing plate close to the scraper, and the fixing plate is fixed on the fixing plate, so that the fixing plate can be kept in a state of rotation and the fixing plate can be kept in a state of rotation. The movable plate moves with the roller, and the roller contacts the surface of the main body and rotates through friction with the main body, and the roller drives the screw to rotate. At this time, the threaded block and the interference disk conflict with each other, and the triangular clamping block is stuck in the limiting tooth, so that the interference disk cannot rotate, and the threaded block cannot rotate either. Therefore, the threaded block can be pushed on the interference disk to push the scraper to the side close to the fixed plate. After moving a certain distance, the interference rod on the fixed plate can contact the triangular clamping block, so that the triangular clamping block is no longer stuck in the limiting tooth, thereby releasing the limit of the interference disk, and the interference disk can be rotated at this time. Therefore, when the roller continues to drive the screw to rotate, the screw will only rotate with the threaded block, thereby controlling the contact between the scraper and the side of the guide groove without affecting the normal rotation of the roller.

[0010] Preferably, a ratchet is provided on the inner side of the through hole, and a pawl is provided on the surface of the resistance plate. When the movable plate is pulled to reset, the roller rotates in the opposite direction. At this time, the screw drives the threaded block to rotate, and the threaded block resists the resistance plate, causing the resistance plate to rotate. However, since the pawl on the surface of the resistance plate is stuck on the ratchet on the inner side of the through hole at this time, the resistance plate cannot rotate, and the threaded block cannot rotate. Under the action of the reset spring, the scraper and the threaded block gradually reset, so that when the movable plate is pulled to reset, the scraper cannot conflict with the side wall of the guide groove, thereby avoiding bringing dirt back.

[0011] Preferably, the slide rail is inclined. When the movable plate is pulled to drive the scraper to clean the guide groove, the movable plate gradually moves along the slide rail toward the side close to the main body, so that the scraper can contact the inner wall of the guide groove for cleaning.

[0012] Compared with the existing technology, the present invention provides a new type of homogeneous membrane electrodialysis water distributor, which has the following beneficial effects:

[0013] 1. This new homogeneous membrane electrodialysis water distributor has a cleaning component that can control the scraper to clean the guide groove by pulling the movable plate, effectively avoiding the phenomenon of dirt clogging in the guide groove, which causes the guide groove to become narrower, the water flow rate to decrease, and the impact on the normal progress of the electrodialysis process.

[0014] 2. This new homogeneous membrane electrodialysis water distributor uses laser welding to weld the lugs and lug flash. Under the action of the laser, the lug flash fuses to the lug, connecting the body and the separator as a whole, ensuring that the body will not fall off during use. The positive and negative flow channel design reduces the contact surface between the membrane and the guide groove and increases the sealing surface between the membrane and the guide groove, which can effectively prevent fouling and leakage. The guide groove adopts an arc design to ensure the water distribution angle while maintaining a smooth flow channel, effectively reducing water flow resistance and making the water distribution more uniform.

[0021] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a new type of homogeneous membrane electrodialysis water distributor, including a body 1, a guide groove 2 is formed on the front and back of the body 1, a sealing thread 5 is provided on the front and back of the body 1, a welding ear 6 is provided on the side of the body 1, and a welding ear flash 7 is welded on the welding ear 6. A cleaning assembly for cleaning the guide groove 2 is provided on the front and back of the body 1, the cleaning assembly is composed of a cleaning part 3 and a driven control part 4, the welding ear 6 and the welding ear flash 7 are welded by laser welding. Under the action of the laser, the welding ear flash 7 is integrated with the welding ear 6, connecting the body 1 and the partition into a whole, ensuring that the body 1 will not fall off during use. The positive and negative flow channel design reduces the contact surface between the membrane and the guide groove 2 and increases the sealing surface between the membrane and the guide groove 2, which can effectively prevent the occurrence of fouling and water leakage problems. The guide groove 2 adopts an arc design to ensure the water distribution angle while maintaining a smooth flow channel, effectively reducing water flow resistance and making the water distribution more uniform.

[0022] The cleaning portion 3 includes a slide rail 31, which is fixed on the surface of the main body 1. The slide rail 31 is slidably connected to the movable plate 32. The side of the movable plate 32 close to the main body 1 is penetrated by the scraper 33 and is slidably connected to the scraper 33. A movable groove 34 is provided on the side of the movable plate 32 close to the main body 1. A fixed plate 35 is fixed on the inner side of the movable groove 34. A return spring 36 is fixed on the side of the scraper 33 close to the fixed plate 35. The end of the return spring 36 away from the scraper 33 is fixed to the fixed plate 35. The scraper 33 can be driven to move by pulling the movable plate 32. The scraper 33 interface cleans the inner side of the guide groove 2 to avoid the guide groove 2 from being blocked by dirt, causing the guide groove 2 to become narrower, the water flow rate to be reduced, and affecting the normal progress of the electrodialysis process. A through hole 8 is provided in the center of the scraper 33.

[0023] The driven control part 4 includes a roller 41, which passes through the movable groove 34. The roller 41 is penetrated by a screw 42 and is fixedly connected to the screw 42. The end of the screw 42 away from the scraper 33 is rotatably mounted on the side of the support plate 43. The support plate 43 is fixed on the inner wall of the movable plate 32. The screw 42 passes through the threaded block 44 and is threadedly connected to the threaded block 44. A contact plate 45 is rotatably mounted on the inner side of the central through hole 8 of the scraper 33. The end of the contact plate 45 away from the threaded block 44 is fixed to the inner wall of the movable plate 32. A limiting tooth 46 is provided on the side, a triangular block 47 is slidably installed on the inner side of the through hole 8, a connecting spring 48 is fixed on the inner side of the through hole 8, and the end of the connecting spring 48 away from the through hole 8 is fixed to the triangular block 47. A resistance rod 49 is fixed on the side of the fixed plate 35 close to the scraper 33. Under the action of the reset spring 36, the scraper 33 is firmly in contact with the resistance disc 45 and the threaded block 44. When the moving plate 32 is pulled to drive the scraper 33 to move, the moving plate 32 brings the roller When the roller 41 continues to drive the screw 42 to rotate, the screw 42 will only rotate with the threaded block 44, so that the scraper 33 is controlled to contact the side of the guide groove 2 without affecting the normal rotation of the roller 41.

[0024] A ratchet 9 is provided on the inner side of the through hole 8, and a pawl 10 is provided on the surface of the contact plate 45. When the movable plate 32 is pulled to reset, the roller 41 rotates in the opposite direction. At this time, the screw 42 drives the threaded block 44 to rotate, and the threaded block 44 abuts against the contact plate 45, causing the contact plate 45 to rotate. However, since the pawl 10 on the surface of the contact plate 45 is stuck on the ratchet 9 on the inner side of the through hole 8 at this time, the contact plate 45 cannot rotate, and the threaded block 44 cannot rotate. Under the action of the reset spring 36, the scraper 33 and the threaded block 44 gradually reset, so that when the movable plate 32 is pulled to reset, the scraper 33 cannot conflict with the side wall of the guide groove 2, thereby avoiding bringing dirt back.

[0025] The slide rail 31 is inclined. When the movable plate 32 is pulled to drive the scraper 33 to clean the guide groove 2, the movable plate 32 gradually moves along the slide rail 31 toward the side close to the body 1, so that the scraper 33 can contact the inner wall of the guide groove 2 for cleaning.

[0026] Based on the above embodiment, when the guide groove 2 is blocked by dirt and becomes narrower as a whole and the water flow is reduced, the movable plate 32 is pulled, and the movable plate 32 drives the scraper 33 to move together, and the movable plate 32 moves together with the roller 41. The roller 41 contacts the surface of the main body 1 and rotates by friction with the main body 1. The roller 41 drives the screw 42 to rotate. At this time, since the threaded block 44 and the contact plate 45 contact each other, and the triangular clamping block 47 is stuck in the limiting tooth 46, the contact plate 45 cannot rotate, and the threaded block 44 cannot rotate either, so that the threaded block 44 can be pushed on the contact plate 45. The movable scraper 33 moves toward the side close to the fixed plate 35. After moving a certain distance, the interference rod 49 on the fixed plate 35 can interfere with the triangular block 47, so that the triangular block 47 is no longer stuck in the limiting tooth 46, thereby releasing the limit on the interference plate 45. At this time, the interference plate 45 can rotate, so that when the roller 41 continues to drive the screw 42 to rotate, the screw 42 will only rotate with the threaded block 44, thereby controlling the scraper 33 to contact the side of the guide groove 2 without affecting the normal rotation of the roller 41. As the scraper 33 moves, the scraper 33 can clean the dirt in the guide groove 2.

[0027] After cleaning, just pull the movable plate 32 to reset. At this time, the roller 41 rotates in the opposite direction. At this time, the screw 42 drives the threaded block 44 to rotate. The threaded block 44 contacts the contact plate 45, causing the contact plate 45 to rotate. However, since the pawl 10 on the surface of the contact plate 45 is stuck on the ratchet 9 on the inner side of the through hole 8 at this time, the contact plate 45 cannot rotate, and the threaded block 44 cannot rotate. Under the action of the reset spring 36, the scraper 33 and the threaded block 44 gradually reset, so that when the movable plate 32 is pulled to reset, the scraper 33 cannot contact the side wall of the guide groove 2, thereby avoiding bringing dirt back.

[0028] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
