Description

Technical Field

[0001] This invention relates to the field of water treatment technology, specifically to a device for continuous electro-desalination filter media filling. Background Technology

[0002] Electro-deionization filter media filling involves filling the chamber of the EDI water purification equipment with a pre-mixed anion and cation resin. During filling, air must be expelled, compacted, and sealed. The patent published in China with announcement number CN224257813U discloses a device for continuous electro-deionization filter media filling. The bottom center of the swing main beam is rotatably connected to the base via a rotating shaft, and the left and right sides of the bottom of the swing main beam are respectively connected to the base via hydraulic cylinders. A cylindrical shell fixing structure is slidably provided on the upper surface of the swing main beam to fix the cylindrical shell. A filter media installation telescopic mechanism is provided on the right cross slide, and a servo telescopic mechanism is provided on the left cross slide. The filter media installation telescopic mechanism and the servo telescopic mechanism cooperate to fill the filter media. During the filling process of electrostatic desalination filter media, a bridging effect is easily generated inside the cylindrical shell of the filter media, which leads to the formation of air bubbles inside the media. These air bubbles reduce the resin exchange area, cause short circuits in the water flow, reduce the quality of the produced water, and also wear down the resin, shortening its service life.

A spring is fixedly connected to the front of the sliding plate and is fixedly connected to the limiting plate. A positioning plate is fixedly connected to the bottom of the sliding plate.

[0010] Preferably, the rotating assembly includes a rotating wheel, which is disposed on the front of the fixed bracket. Multiple inner support rollers are movably connected inside the pad frame, and multiple outer support rollers are disposed inside the outer locking plate. Rotary sealing plates are movably connected to the side of the first electric telescopic rod near the mounting circular plate.

[0011] Preferably, the striking assembly includes a striking plate, which is disposed on the outer wall of the corresponding extension plate and is located on one side of the extension plate clockwise.

[0012] This invention provides an apparatus for continuous electro-desalination filter media filling. It has the following beneficial effects: 1. This device for continuous electro-deionization filter media filling involves filling the electro-deionization filter media inside the cylindrical shell in multiple steps, with each layer being added and turned over to achieve self-weight compaction. At the same time, the cylindrical shell is inverted and turned over during the filling process, relying on the self-weight of the resin to disperse the anion and cation resins, avoiding the formation of bridging voids on the inner wall of the cylindrical arc, preventing the material from sliding down and filling dead corners, and avoiding the formation of voids inside the filling.

[0013] 2. This device for continuous electro-deionization filter media filling causes the cylindrical outer shell to rotate while being driven to rotate. The rotation generates a slight centrifugal force, which causes the resin inside to adhere tightly to the arc-shaped inner wall of the cylinder, eliminating gaps around the cylinder wall and making the filling more full. It further breaks up the agglomeration and stratification of the anion and cation resins. At the same time, the air bubbles inside the cylinder are gathered towards the center due to centrifugal force, making them easier to expel when the cap is opened, thus avoiding the formation of voids inside the filling.

[0014] 3. The device for continuous electro-deionization filter media filling uses the rotating cylindrical shell to strike the shell, thereby disrupting the bridging void structure and reducing the adhesion of resin clumps on the cylinder wall. This makes the internal particles interlock and the overall structure more compact. In addition, the vibration can promote the smooth discharge of air bubbles, ensuring uniform filling density of the filter media inside the cylinder and preventing voids from forming inside the filling.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0019] Example 1: Please refer to Figure 1-7 The present invention provides a technical solution: a device for continuous electro-desalination filter media filling, comprising a fixed support 1, a fixed plate 2 fixedly connected to the front of the fixed support 1, a flipping component provided on the front of the fixed plate 2, the flipping component including a mounting circular plate 3 and a sealing component 5, the mounting circular plate 3 being movably connected to the front of the fixed plate 2, two sealing components 5 being fixedly connected to the outer wall of the mounting circular plate 3, the mounting circular plate 3 also including a fixing component 4, the fixing component 4 being fixedly connected to the front of the mounting circular plate 3, a feeding component 6 being fixedly connected to the front of the fixed plate 2, and a tapping mechanism provided on the outer wall of the sealing component 5, the tapping mechanism including a tapping component 7 and a rotating component 8, both the tapping component 7 and the rotating component 8 being provided on the outer wall of the sealing component 5.

[0020] The cylindrical shell that needs to be filled with electro-deionized filter media is placed into the fixing component 4 of the mounting plate 3 on the front side of the mounting plate 3 and fixed. The bottom of the cylindrical shell of the electro-deionized filter media is sealed by the sealing component 5. The electro-deionized filter media is put into the feeding component 6 and the feeding component 6 fills the inside of the cylindrical shell with electro-deionized filter media. A drive motor 31 is fixedly connected to the back of the fixed plate 2. The output shaft of the drive motor 31 passes through the fixed plate 2 and is fixedly connected to the mounting circular plate 3.

[0021] After the cylindrical shell is fixed to the front of the fixed bracket 1 by the fixing component 4, during the filling process, after each portion of the electro-deionizing filter material is filled, the sealing component 5 seals the top opening of the cylindrical shell. Then, the mounting plate 3 can be driven by the drive motor 31 to rotate, further driving the cylindrical shell to rotate, causing the cylindrical shell to turn upside down, so that the electro-deionizing filter material already filled inside the cylindrical shell will flip and move inside the cylindrical shell. Then, the sealing component 5 will release the seal on the top of the cylindrical shell, and the filling will continue. This flipping process continues until the shell is full.

[0022] During this process, the electro-desalting filter media can be tumbled and moved inside the cylindrical shell; After a small amount of filler is added, the cylindrical outer shell is flipped over. The resin can be dispersed by its own weight, avoiding the imbalance of the ratio caused by density difference. The curved inner wall of the cylinder is prone to bridging voids. Repeated inversion can allow the material to slide down and fill the dead corners, while releasing the material layer that encapsulates air bubbles. In addition, the layer-by-layer feeding and turning process achieves self-weight compaction, eliminating the need for high-pressure impact in conventional filling. This protects the resin and internal membrane components, effectively improving the overall density and uniformity of the filter media inside the cylinder, and ensuring stable operation of the electro-deionization process.

[0023] After filling, the sealing structure of the cylindrical shell can be installed on the top of the cylindrical shell first. Then, the drive motor 31 can drive the mounting plate 3 to rotate, so that the original bottom of the cylindrical shell moves to the top. At this time, the sealing component 5 can no longer seal the corresponding end of the cylindrical shell, which makes it easier to install the sealing structure on the other end of the cylindrical shell.

[0024] The fixing component 4 includes a pad 41, which is fixedly connected to the front of the mounting plate 3. Fastening motors 42 are fixedly connected to the front of the mounting plate 3 on both the left and right sides of the pad 41. Threaded rods 43 are fixedly connected to the output shafts of the fastening motors 42. An outer locking plate 44 is provided on the front of the pad 41, and the outer locking plate 44 is movably connected to the threaded rods 43 via threads.

[0025] The cylindrical outer shell is placed on the front of the pad 41 using an external clamping device, and then the corresponding position of the outer locking plate 44 is aligned with the threaded rod 43. The fastening motor 42 then drives the corresponding threaded rod 43 to rotate, so that the outer locking plate 44 and the pad 41 work together under the action of the thread to fix the cylindrical outer shell and prevent it from sliding down. After fixing, the external clamping device can be pulled away. After filling, the cylindrical outer shell is fixed by the external clamping device, and the threaded rod 43 is driven in the opposite direction to remove the outer locking plate 44, making it easy to remove the filled cylindrical outer shell.

[0026] The sealing assembly 5 includes an extension plate 51, which is fixedly connected to the outer wall of the mounting circular plate 3. A first electric telescopic rod 52 is fixedly connected to the front of the extension plate 51, and a sealing plate 53 is fixedly connected to the telescopic end of the first electric telescopic rod 52 near the mounting circular plate 3.

[0027] The extension plate 51 can extend and retract, pushing the first electric telescopic rod 52 at its corresponding telescopic end, so that the first electric telescopic rod 52 moves to the upper and lower ends of the cylindrical shell, thereby sealing both ends of the cylindrical shell during the filling process.

[0028] The feeding assembly 6 includes a second electric telescopic rod 61, which is fixedly connected to the front of the fixed plate 2. The telescopic end of the second electric telescopic rod 61 is fixedly connected to a feeding channel 62, and a feeding assembly 63 is provided at the bottom of the feeding channel 62.

[0029] During filling, the second electric telescopic rod 61 pulls the feed channel 62 through the telescopic end to move it, so that the discharge port at the bottom of the feed channel 62 moves to the top of the cylindrical shell, and the discharge assembly 63 releases the blocking effect on the bottom of the feed channel 62, so that the electro-deionizing filter material can be added into the cylindrical shell through the feed channel 62.

[0030] The feeding assembly 63 includes a limiting plate 631, which is fixedly connected to the bottom of the feeding channel 62. A sliding plate 632 is movably connected to the bottom of the feeding channel 62 and is movably connected to the back of the limiting plate 631. A spring 633 is fixedly connected to the front of the sliding plate 632 and is fixedly connected to the limiting plate 631. A locking plate 634 is fixedly connected to the bottom of the sliding plate 632.

[0031] The second electric telescopic rod 61 retracts, causing the feeding channel 62 to move towards the top of the cylindrical shell. During this process, the locking plate 634 at the bottom of the sliding plate 632 is blocked by the cylindrical shell, causing the sliding plate 632 to stop moving and the spring 633 to retract. When the feeding channel 62 moves to the top of the cylindrical shell, the sliding plate 632 moves from the bottom of the feeding channel 62, allowing the feeding channel 62 to start discharging when it reaches the top of the cylindrical shell. Subsequently, when the cylindrical shell needs to be flipped, the second electric telescopic rod 61 extends, pushing the feeding channel 62 to move forward. At this time, the spring 633 resets and pushes the sliding plate 632 to reset, resealing the bottom of the feeding channel 62, thereby stopping the discharge when the feeding channel 62 moves away from the top of the cylindrical shell.

[0032] Example 2: Please refer to Figure 1-9 Based on Embodiment 1, the present invention provides a technical solution: The rotating assembly 8 includes a rotating wheel 81, which is disposed on the front of the fixed bracket 1. Multiple inner support rollers 83 are movably connected inside the pad frame 41. Multiple outer support rollers 82 are disposed inside the outer locking plate 44. Rotating sealing plates 84 are movably connected to the side of the first electric telescopic rod 52 near the mounting circular plate 3. The rotating sealing plates 84 can rotate around the center of the first electric telescopic rod 52. A soft layer is disposed on the top of the rotating sealing plate 84, which can tightly fit one end of the cylindrical shell under the action of extrusion pressure, thus achieving a good sealing effect.

[0033] The outer wall of the roller 81 is provided with a rubber layer. When the cylindrical shell is fixed by the fixing component 4, the rubber layer of the roller 81 will be squeezed and compressed, so that the outer side of the roller 81 can fully contact the outer wall of the cylindrical shell and the front of the fixing plate 2, providing strong friction. In addition, the outer walls of the outer support roller 82 and the inner support roller 83 are also provided with rubber layers. The rubber layers can prevent the cylindrical shell from deforming due to strong clamping when the fixing component 4 fixes the cylindrical shell. At the same time, the outer support roller 82 and the inner support roller 83 can provide rolling support for the cylindrical shell, so that the cylindrical shell can rotate around the axis when fixed.

[0034] When the drive motor 31 drives the mounting circular plate 3 and drives the cylindrical shell to rotate through the fixing component 4, the extension plate 51 can drive the rotating wheel 81 to rotate. Since the outer wall of the rotating wheel 81 is in contact with the outer wall of the fixing plate 2, the rotating wheel 81 can roll and rotate on the top of the fixing plate 2. Through the contact between the outer wall of the rotating wheel 81 and the cylindrical shell, the cylindrical shell can be driven to rotate by the mounting circular plate 3 and rotate around the axis.

[0035] During this process, the cylindrical outer shell is driven to rotate, generating a slight centrifugal force, which causes the resin inside to adhere tightly to the arc-shaped inner wall of the cylinder, eliminating gaps around the cylinder wall and filling it more fully; the continuous stirring of the filter material further breaks up the agglomerates and stratifies the anion and cation resins, resulting in higher mixing uniformity; the air bubbles inside the cylinder are gathered towards the center due to centrifugal force, making them easier to expel when the lid is opened.

[0036] The striking assembly 7 includes a striking plate 71, which is disposed on the outer wall of the corresponding extension plate 51 and is located on one side of the extension plate 51 clockwise. The striking plate 71 is movably connected to the upper and lower sides of the striking plate 71, and the mounting seats 72 are fixedly connected to the outer wall of the corresponding extension plate 51. The striking plate 71 is fixedly connected to the upper and lower sides of the striking plate 71, and the torsion springs 73 are respectively fixedly connected to the corresponding mounting seats 72. The front of the fixing plate 2 is provided with a plurality of actuating protrusions 74 that cooperate with the striking plate 71.

[0037] When the mounting plate 3 rotates, it can synchronously drive the extension plate 51 to rotate. The extension plate 51, in turn, drives the striking plate 71 to rotate on the front of the fixed plate 2 via the mounting base 72. During the rotation, the side of the striking plate 71 closest to the fixed plate 2 is pushed by the actuating protrusion 74, causing the striking plate 71 to rotate around its connection with the mounting base 72. This further causes the torsion spring 73 to twist and deform. As the extension plate 51 rotates, the striking plate 71 will disengage from the actuating protrusion 74. Subsequently, the striking plate 71 will return to its original position under the elastic force of the torsion spring 73, thereby causing the striking plate 71 to strike the outer wall of the cylindrical shell, which in turn causes the resin inside the cylindrical shell to vibrate.

[0038] During this process, the vibration generated by the impact on the outer wall can break up the bridging voids formed by the resin inside the cylinder, and peel off the resin clumps adhering to the arc-shaped cylinder wall. The rotation of the outer shell can continuously tumble and mix the materials, effectively inhibiting the stratification of the anion and cation resins due to density differences. The vibration drives the particles to interlock with each other, making the whole more compact. At the same time, the air bubbles that are concentrated in the center of the cylinder by centrifugal force can be further discharged smoothly under the action of vibration disturbance. Ultimately, the filter material in each radial area of ​​the cylinder is filled with uniform density, avoiding the formation of local void defects.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
