Abstract

This invention relates to the field of corrugated paper production technology, specifically to a wastewater treatment device for corrugated paper production. The device includes a base, a fixed platform fixedly connected to one side of the base, a filter box snapped into the fixed platform, and a fixed plate fixedly connected to the inside of the filter box. An installation assembly is installed inside the fixed plate. Through the cooperation of the circumferential linkage sleeve and the first locking block, multiple sets of filter screens can be simultaneously disassembled and assembled, as well as one side can be independently disassembled and assembled. When two sets of circumferential linkage sleeves are respectively snapped into two sets of first locking blocks, rotating the first threaded tube on one side can drive two sets of movable plates to move synchronously, achieving unified reference and synchronous positioning for disassembly and assembly of multiple sets of filter screens, ensuring consistent positioning during repeated installations. When the circumferential linkage sleeve disengages from the first locking block, one side of the filter screen can be disassembled individually, meeting the needs of local independent maintenance. This device can accommodate both independent maintenance and synchronous assembly scenarios, offering convenient and efficient operation and effectively reducing maintenance workload and disassembly / assembly steps.

Description

Technical Field

[0001] This invention relates to the field of corrugated paper production technology, specifically to a wastewater treatment device for corrugated paper production. Background Technology

[0002] As is well known, the production of corrugated paper generates a large amount of production wastewater containing pollutants such as pulp fibers, adhesives, fillers, and pigments. This wastewater must be filtered and purified to meet standards before it can be discharged or reused. Filtration, as the core link in wastewater pretreatment, usually adopts a multi-stage, layered, double-sided multi-set filter structure. Suspended impurities and fibers are intercepted step by step through filter screens with different pore sizes to ensure the effect of subsequent treatment.

[0003] To simplify the structure and reduce manufacturing costs, the filtration structure in wastewater treatment devices for corrugated paper production generally adopts a design where multiple filter units on both sides share the same set of mounting and fixing components. The filter screens of different levels on both sides are uniformly fixed on a common mounting base or bracket to form an integrated filtration structure. Although this design can reduce the number of parts and simplify the assembly process, it has obvious and difficult-to-overcome defects in assembly, maintenance and use.

[0004] For example, a small corrugated wastewater treatment device with announcement number CN120040047A has multiple layers of fixed plates inside its treatment tank, fixed from top to bottom. Both sides and the multiple filter layers share the same installation and fixing structure. All filter screens are uniformly fixed inside the tank by an integrated installation mechanism. This structure has two drawbacks: firstly, when a filter screen on one side becomes clogged or damaged and requires maintenance, the single-side filter structure cannot be disassembled individually; the entire multi-layered and double-side filter unit must be disassembled, making maintenance cumbersome; secondly, when reinstalling after disassembly, misalignment of multiple filter screens is likely to occur, affecting the consistency of repeated installations. Poor performance affects filtration efficiency and operational stability. For example, a wastewater treatment device for a corrugated paper production workshop, with announcement number CN220976632U, has a filter tank and multiple internal filter structures that share the same fixed bracket and mounting base, all assembled in the equipment box. This structure also has a common defect: the filter components on both sides share the mounting base, and the filter unit on one side cannot be disassembled and maintained independently; it can only be disassembled as a whole. Moreover, the disassembly and assembly process is cumbersome, and after multiple disassemblies and assemblies, it is difficult to guarantee the installation alignment accuracy and positional consistency of each filter structure, which cannot meet the dual requirements of flexible maintenance and stable assembly.

[0005] By comparing proportions and existing conventional devices, it can be seen that current corrugated paper wastewater treatment filtration devices suffer from a core technical contradiction that cannot be addressed simultaneously. When using an integrated structure with shared installation components, the single-sided filter structure cannot be independently disassembled and maintained; it must be disassembled as a whole. This not only involves cumbersome disassembly and assembly procedures but also easily leads to problems such as difficulty in alignment and poor consistency in repeated installation positions after overall disassembly and assembly. While using multiple completely independent installation structures allows for independent disassembly and assembly on one side, it results in a significant increase in the number of parts, structural complexity, and reduced overall assembly efficiency, which also fails to meet the usage requirements. In short, existing wastewater treatment devices for corrugated paper production cannot simultaneously achieve independent disassembly and maintenance of a single-sided filter structure, synchronous assembly and positioning of multiple filter structures, and ensure consistency in repeated installation positions. It is difficult to balance the flexibility, convenience, and stability of assembly and maintenance. Summary of the Invention

[0006] To overcome the problems of existing wastewater treatment devices for corrugated paper production, which suffer from multiple filter structures on both sides sharing the same installation components, resulting in the inability to independently disassemble and maintain one side, cumbersome disassembly and assembly operations, difficulty in reinstallation and alignment, and poor positional consistency, and thus cannot simultaneously achieve independent maintenance and synchronous assembly, this invention provides a wastewater treatment device for corrugated paper production that features independently disassembly and assembly of a single-side filter structure, synchronous assembly and positioning of multiple filter structures, good positional consistency during repeated installation, and convenient maintenance operations.

The reference linkage shaft and the first threaded tubes are selectively engaged and disengaged to enable the mounting components to achieve independent single-side assembly and disassembly of multiple sets of filter screens and simultaneous assembly and disassembly of multiple sets. After the fixing block is engaged with the mounting hole, the filter screen will be stably installed in the filter box. After the fixing block is disengaged from the mounting hole, the filter screen will no longer be fixed, and at this time, the filter screen on one side can be easily removed from the filter box.

[0009] Preferably, the mounting assembly further includes two sets of second threaded tubes, two sets of linkage switching push blocks, and two sets of fixed discs. The second threaded tubes are rotatably disposed inside the fixed plate. Both ends of the reference linkage shaft are provided with second locking blocks.

[0010] Preferably, both sides of the linkage switching push block are slidably disposed inside the fixed plate, and two sets of second springs are fixedly disposed on the side of the linkage switching push block near the fixed plate, and the end of the second spring away from the linkage switching push block is fixedly disposed inside the fixed plate.

[0011] Preferably, a fixed column is rotatably provided on one side of the swing plate, and the fixed column is fixedly disposed inside the fixed plate.

[0012] Preferably, one side of the movable plate is provided with two sets of placement racks, and a movable shaft is rotatably arranged between the two sets of placement racks. One side of the swing plate is slidably arranged outside the movable shaft.

[0013] Preferably, two sets of baffles are provided on the outer side of the movable shaft, and the two sets of baffles are located on both sides of the two sets of placement racks.

[0014] Preferably, a rotating column is fixedly provided at one end of the first threaded tube, and the rotating column is rotatably disposed inside the fixed plate, and a first locking block is provided at the end of the rotating column away from the first threaded tube.

[0017] 1. This wastewater treatment device for corrugated paper production, through the cooperation of the circumferential linkage sleeve and the first locking block, can flexibly realize the synchronous disassembly and assembly of multiple sets of filter screens and the independent disassembly and assembly of one side. When the two sets of circumferential linkage sleeves are respectively locked into the two sets of first locking blocks, rotating the first threaded pipe on one side can drive the two sets of movable plates to move synchronously, realizing the unified benchmark and synchronous positioning disassembly and assembly of multiple sets of filter screens, ensuring the consistency of repeated installation. When the circumferential linkage sleeve is disengaged from the first locking block, the filter screen on one side can be disassembled separately to meet the needs of local independent maintenance. This device can take into account both independent maintenance and synchronous assembly usage scenarios, and is convenient and efficient to operate, effectively reducing the workload of maintenance and disassembly and assembly steps.

[0018] 2. This wastewater treatment device for corrugated paper production, by setting up a connecting component, will cause the parallel plate to move as the toggle block moves. At this time, the mounting plate is no longer stuck inside the movable frame, and the operator can then easily disassemble the movable frame and the filter screen. When the mounting plate is stuck inside the movable frame, the movable frame and the filter screen will be stably installed on one side of the support plate. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] See Figures 1-15 A wastewater treatment device for corrugated paper production includes a base 1. A mixing tank 4 and a fixed platform 5 are fixedly connected to one side of the base 1. The fixed platform 5 is used to filter impurities in the wastewater, and the mixing tank 4 is used to mix the filtered wastewater and water treatment agents. A filter box 8 is snapped into the inside of the fixed platform 5. A fixed plate 6 is fixedly connected into the inside of the filter box 8. An installation component 2 is provided inside the fixed plate 6. Four sets of support plates 11 are snapped into the inside of the filter box 8. Two sets of movable frames 10 are snapped between two sets of support plates 11. A filter screen 9 is fixedly connected into the inside of the movable frame 10. The filter screen 9 is used to filter impurities in the wastewater. A connecting component 3 is provided inside the support plate 11. Mounting holes 12 are opened on both sides of the support plate 11. Four sets of slots 13 are opened on one side of the movable frame 10.

[0023] First, refer to Figures 2 to 11 In this embodiment, the mounting assembly 2 includes a reference linkage shaft 202, two sets of movable plates 201, two sets of first threaded pipes 215, and two sets of second threaded pipes 231. The reference linkage shaft 202 is rotatably connected to the inside of the fixed plate 6. Second locking blocks 234 are fixedly connected to both ends of the reference linkage shaft 202. A circumferential linkage sleeve 228 is slidably connected to the outer side of the second locking block 234. A movable groove is formed inside the circumferential linkage sleeve 228, and the shape of the inner wall of the movable groove is adapted to the second locking block 234. The movable groove and the second locking block 234... The 34-adaptive design enables synchronous rotation of the circumferential linkage sleeve 228 and the reference linkage shaft 202, while ensuring that the circumferential linkage sleeve 228 can slide along the axial direction of the reference linkage shaft 202, providing a structural basis for transmission switching. The outer side of the circumferential linkage sleeve 228 is fixedly connected to a fixed disk 229 and a linkage switching push block 227. Two sets of protrusions 230 are fixedly connected to the side of the linkage switching push block 227 away from the fixed disk 229. The protrusions 230 are arc-shaped. Both sides of the linkage switching push block 227 are slidably connected to the inside of the fixed plate 6.

[0024] Specifically, in order to enable the linkage switching push block 227 to move back quickly, two sets of second springs 225 are fixedly connected to one side of the linkage switching push block 227. The end of the second spring 225 away from the linkage switching push block 227 is fixedly connected to the inside of the fixing plate 6. Thus, when the linkage switching push block 227 is pushed, the second spring 225 will be squeezed by the linkage switching push block 227, and when the linkage switching push block 227 is no longer pushed, the second spring 225 will bounce and the linkage switching push block 227 will move back quickly.

[0025] Two sets of movable plates 201 are slidably connected to both sides of the fixed plate 6. Two sets of fixed blocks 235 are fixedly connected to one side of the movable plate 201, and the fixed blocks 235 are snapped into the inside of the mounting hole 12. Two sets of sliders 205 are fixedly connected to both sides of the movable plate 201. Two sets of placement racks 209 are fixedly connected to the side of the movable plate 201 away from the fixed blocks 235. A movable shaft 211 is rotatably connected between the two sets of placement racks 209. Two sets of swing plates 203 are slidably connected to the outside of the movable shaft 211. The swing plates 203 are inclined, and the four sets of swing plates 203 are inclined in the same direction. A fixed column 204 is rotatably connected to the side of the swing plate 203 away from the movable shaft 211, and the fixed column 204 is fixedly connected inside the fixed plate 6.

[0026] Specifically, in order to maintain the balance of the slider 205, a limiting rod 208 is slidably connected inside the slider 205. One end of the limiting rod 208 is fixedly connected inside the fixed plate 6. Thus, on the one hand, the limiting rod 208 maintains the balance of the slider 205 during movement, preventing the slider 205 from becoming unbalanced and wobbling during movement, and ensuring the normal displacement of the slider 205. On the other hand, the limiting rod 208 restricts the direction of the slider 205, preventing the device from failing due to misalignment of the slider 205, and ensuring the normal use of the device.

[0027] Meanwhile, in order to enable the movable plate 201 to move back quickly, a disc 206 is slidably connected to the outside of the limiting rod 208. A first spring 207 is fixedly connected to one side of the disc 206, and the end of the first spring 207 away from the disc 206 is fixedly connected to the inside of the fixed plate 6. Thus, when the movable plate 201 is pushed, the disc 206 will be squeezed by the slider 205. At this time, the first spring 207 will be squeezed by the disc 206. When the movable plate 201 is no longer pushed, the first spring 207 will bounce the movable plate 201 back quickly by bouncing the disc 206 and the slider 205 back.

[0028] Specifically, in order to prevent the movable shaft 211 from detaching from the placement frame 209, two sets of baffles 210 are fixedly connected to the outside of the movable shaft 211, and the two sets of baffles 210 are located on both sides of the two placement frames 209 respectively. Thus, the movable shaft 211 can be blocked by the baffles 210 to prevent the movable shaft 211 from detaching from the placement frame 209.

[0029] The first threaded tube 215 is rotatably connected to the inside of the fixed plate 6. A rotating column 217 is fixedly connected to one end of the first threaded tube 215. A first locking block 223 is fixedly connected to the end of the rotating column 217 away from the first threaded tube 215. The vertical cross-section of the first locking block 223 and the second locking block 234 are both hexagonal, and the first locking block 223 is parallel to the circumferential linkage sleeve 228. An installation tube 221 is rotatably connected to the outside of the rotating column 217. Support frames 222 are fixedly connected to both sides of the installation tube 221. The side of the support frame 222 away from the installation tube 221 is fixedly connected to the inside of the fixed plate 6. A sleeve 214 is threaded onto the outside of the first threaded tube 215. The first threaded tube 215 plus the sleeve 214 can achieve stable transmission and avoid uneven force during manual disassembly. A connecting frame 216 is fixedly connected to both sides of the sleeve 214. A central shaft 219 is fixedly connected to one side of the connecting frame 216. A follower guide wheel 218 is rotatably connected to the outside of the central shaft 219. The outer side of the guide wheel 218 contacts the swing plate 203. The cooperation between the follower guide wheel 218 and the swing plate 203 can achieve smooth drive and avoid unilateral disassembly jamming. The end of the first threaded tube 215 away from the rotating column 217 passes through the fixed plate 6 and is fixedly connected to the first handle 212 rotatably connected in the filter box 8. A guide plate 213 is fixedly connected to one side of the first handle 212. Guide grooves 7 are opened on both sides of the filter box 8. When the guide plate 213 and the guide groove 7 are parallel, the first locking block 223 will be aligned with the second locking block 234. At this time, the circumferential linkage sleeve 228 can smoothly lock into the outer side of the first locking block 223. The design of the reference linkage shaft 202 and the second locking block 234 is the core structure that solves the problem that the existing technology cannot achieve synchronous transmission on both sides. The device connects the second locking blocks 234 on both sides through the reference linkage shaft 202. With the subsequent locking of the circumferential linkage sleeve 228 and the first locking block 223, the synchronous transmission and unilateral independent transmission modes can be flexibly switched.

[0030] Specifically, in order to prevent the rotating column 217 from being misaligned, two sets of anti-detachment blocks 220 are fixedly connected to the outside of the rotating column 217, and the two sets of anti-detachment blocks 220 are located on both sides of the mounting tube 221, thereby blocking the rotating column 217 and preventing the rotating column 217 from being misaligned.

[0031] The second threaded tube 231 is rotatably connected to one side of the fixed plate 6. A second handle 224 is fixedly connected to one end of the second threaded tube 231. A movable plate 226 is screwed onto the outer side of the second threaded tube 231. The movable plate 226 is slidably connected to the outer side of the two sets of protrusions 230. Two sets of support columns 233 are fixedly connected inside the movable plate 226. Rollers 232 are rotatably connected to the outer side of the support columns 233, and the outer side of the rollers 232 contacts the protrusions 230. The second threaded tube 231 is used to drive the circumferential linkage sleeve 228 to move, thereby realizing the switching of the transmission link.

[0032] When using the mounting component 2, turning the first handle 212 will cause the first threaded tube 215 to rotate. The rotation of the first threaded tube 215 will cause the sleeve 214 to move linearly. The displacement of the sleeve 214 will push the follower guide wheel 218 to move by pushing the connecting frame 216 and the central shaft 219. The displacement of the follower guide wheel 218 will push the swing plate 203. At this time, the swing plate 203 will swing around the fixed column 204 as the axis. The swing of the swing plate 203 will push the movable shaft 211 to move horizontally. The displacement of the movable shaft 211 will push the movable plate 201 to move horizontally by pushing the placement frame 209. The displacement of the movable plate 201 will push the fixed block 235 to move and disengage from the mounting hole 12. At this time, the support plate 11 on one side is no longer fixed. Then the operator can disassemble the support plate 11 on one side, the movable frame 10 and the filter screen 9.

[0033] When it is necessary to disassemble the support plates 11 on both sides simultaneously, first ensure that the guide plate 213 is aligned with the guide groove 7, and then turn the two sets of second handles 224. The rotation of the second handles 224 will drive the second threaded tube 231 to rotate, and the rotation of the second threaded tube 231 will drive the moving plate 226 to move longitudinally. The displacement of the moving plate 226 will drive the roller 232 to move longitudinally by pushing the support column 233. The displacement of the roller 232 will drive the protrusion 230 to move horizontally. The displacement of the protrusion 230 will drive the circumferential linkage sleeve 228 to move horizontally by pushing the linkage switching push block 227. At this time, the circumferential linkage sleeve 228 will be engaged with the outside of the first locking block 223. The hexagonal cooperation between the circumferential linkage sleeve 228, the first locking block 223, and the second locking block 234 can achieve precise positioning during the transmission process, ensuring that the rotation speed of the first threaded tubes 215 on both sides is consistent and the displacement of the moving plate 203 is synchronized. To ensure uniform positioning of multiple filter screens 9 after disassembly and assembly, and to address the shortcomings of existing technologies such as misalignment and poor consistency in repeated installations after overall disassembly and assembly, when the first handle 212 on one side is turned, the rotation of the first threaded tube 215 will drive the first locking block 223 to rotate through the rotating column 217. The rotation of the first locking block 223 will drive the reference linkage shaft 202 to rotate through the circumferential linkage sleeve 228. The rotation of the reference linkage shaft 202 will drive the other set of first threaded tubes 215 to rotate. This allows the two sets of movable plates 201 to move synchronously, and then the support plates 11 on both sides can be disassembled. After the circumferential linkage sleeve 228 disengages from the first locking block 223, the movement of the movable plate 201 on one side is precisely guided by the cooperation of the slider 205 and the limiting rod 208, avoiding misalignment during disassembly and assembly on one side, ensuring the installation accuracy of the filter screen 9 after individual maintenance, and taking into account both local maintenance and positioning stability.

[0034] When installing the support plate 11, movable frame 10, and filter screen 9, first turn the second handle 224 to rotate the second threaded tube 231, causing the circumferential linkage sleeve 228 to shift and engage with the outside of the first locking block 223. Then turn the first handle 212 to rotate the first threaded tube 215. The rotation of the first threaded tube 215 drives the first locking block 223 to rotate via the rotating column 217. The rotation of the first locking block 223 drives the reference linkage shaft 202 to rotate via the circumferential linkage sleeve 228. The rotation of the reference linkage shaft 202 drives the other set of first threaded tubes 215 to rotate. This allows the two sets of movable plates 201 to move synchronously. Then, the movable frame 10 and filter screen 9 are installed. The mesh 9 and support plate 11 are inserted into the filter box 8. At this time, the mounting hole 12 and the fixing block 235 are parallel. The first threaded tube 215 is reversed to make the sleeve 214 move back. The movement of the sleeve 214 will push the follower guide wheel 218 back by pushing the connecting frame 216 and the central shaft 219. At this time, the follower guide wheel 218 no longer pushes the swing plate 203. Then, the first spring 207 will bounce the movable plate 201 back by bouncing the slider 205 back. The movement of the movable plate 201 will bounce the fixing block 235 into the mounting hole 12. At this time, the support plate 11 will be fixed in the filter box 8 by the fixing block 235, thus completing the installation of the support plate 11, the movable frame 10 and the filter mesh 9.

[0035] This wastewater treatment device for corrugated paper production, through the cooperation of the circumferential linkage sleeve 228 and the first locking block 223, can flexibly realize the synchronous disassembly and assembly of multiple sets of filter screens 9 and the independent disassembly and assembly of one side. When the two sets of circumferential linkage sleeves 228 are respectively locked into the two sets of first locking blocks 223, rotating the first threaded pipe 215 on one side can drive the two sets of movable plates 201 to move synchronously, realizing the unified benchmark and synchronous positioning disassembly and assembly of multiple sets of filter screens 9, ensuring the consistency of repeated installation. When the circumferential linkage sleeve 228 is disengaged from the first locking block 223, the filter screen 9 on one side can be disassembled separately to meet the needs of local independent maintenance. This device can take into account both independent maintenance and synchronous assembly usage scenarios, is convenient and efficient to operate, and effectively reduces the workload of maintenance and disassembly and assembly steps.

[0036] The core advantage of this device is that it can freely switch between single-sided independent disassembly and assembly mode and double-sided synchronous disassembly and assembly mode. The switching logic is clear and the operation is convenient. All switching actions are realized based on the structural design of the installation component 2. In essence, the connection / disconnection of the transmission link is controlled by the engagement / disengagement of the circumferential linkage sleeve 228 and the first locking block 223.

[0037] Finally, see Figures 12 to 14In this embodiment, the connecting component 3 includes a fixing frame 301 and two sets of parallel plates 305. The fixing frame 301 is fixedly connected to the inside of the support plate 11, and the parallel plates 305 are slidably connected to the inside of the support plate 11. Two sets of third springs 302 are fixedly connected between the fixing frame 301 and the parallel plates 305. Two sets of mounting plates 303 are fixedly connected to the side of the parallel plates 305 away from the fixing frame 301, and the mounting plates 303 are snapped into the slots 13. A toggle block 304 is fixedly connected to one side of the parallel plates 305. After moving the toggle block 304, the toggle block 304... 04 will push the parallel plate 305 to move horizontally. The displacement of the parallel plate 305 will push the mounting plate 303 to move horizontally and disengage from the slot 13. At this time, the mounting plate 303 will no longer fix the movable frame 10. Then the operator can easily disassemble the single movable frame 10 and the filter screen 9. The connecting component 3 realizes the independent disassembly and assembly of the single filter screen 9, which works in conjunction with the single-sided / synchronous disassembly and assembly mode of the mounting component 2 to form a layered maintenance structure, further improving the maintenance flexibility of the device and solving the defect of the existing technology that either disassembles the whole or disassembles the single set, and cannot take into account the layered maintenance.

[0038] When installing the movable frame 10 and the filter screen 9, push the actuating block 304 to move the parallel plate 305 horizontally. The displacement of the parallel plate 305 will push the mounting plate 303 horizontally. At this time, the parallel plate 305 will squeeze the third spring 302, and then the movable frame 10 will be inserted into the outer side of the parallel plate 305 and the mounting plate 303. At this time, the mounting plate 303 and the slot 13 are parallel. Then release the actuating block 304. At this time, the third spring 302 will bounce the parallel plate 305 back. The back movement of the parallel plate 305 will bounce the mounting plate 303 back. The back movement of the mounting plate 303 will be inserted into the slot 13. At this time, the mounting plate 303 will fix the filter screen 9 by locking the movable frame 10. Thus, the movable frame 10 and the filter screen 9 are installed on the support plate 11, and the installation of the movable frame 10 and the filter screen 9 is completed.

[0039] The wastewater treatment device for corrugated paper production, by setting up a connecting component 3, will cause the parallel plate 305 to push the mounting plate 303 to move after the moving block 304 is moved. At this time, the mounting plate 303 is no longer stuck inside the movable frame 10, and the operator can then easily disassemble the movable frame 10 and the filter screen 9. When the mounting plate 303 is stuck inside the movable frame 10, the movable frame 10 and the filter screen 9 will be stably installed on one side of the support plate 11.

[0040] This invention is not a simple superposition or deliberate complication of existing structures, but rather a necessary, reasonable, and non-simplifiable structural design addressing the technical pain points of existing corrugated paper wastewater filtration devices, which can only be disassembled individually, cannot handle both unilateral maintenance and overall disassembly, and suffer from poor alignment accuracy after disassembly and assembly. Existing technologies generally suffer from problems such as a single disassembly mode, inconvenient maintenance, and cumbersome operation; either they can only be disassembled as a whole, unable to maintain a single side individually, or their structures are loose, resulting in poor positioning accuracy and insufficient stability. This invention addresses these issues through the coordinated operation of components such as the reference linkage shaft 202, the circumferential linkage sleeve 228, and the follower guide wheel 218. This device is the first to achieve free switching between single-sided independent maintenance and double-sided synchronous disassembly and assembly modes on a corrugated paper wastewater treatment unit. All components are necessary to realize this core function, without any redundant or deliberately complicated designs. Furthermore, through hexagonal locking blocks and slider limiting structures, it solves the problems of difficult alignment and poor consistency of repeated installation in existing technologies. The overall structure is compact and the layout is reasonable. Without adding too many complex structures, it significantly improves the flexibility of use and maintenance efficiency, effectively solving the defects of inconvenient maintenance and poor adaptability of traditional devices. It has outstanding substantive features and significant progress. Working principle

[0041] In operation, the wastewater treatment device for corrugated paper production involves turning the first handle 212, which rotates the first threaded tube 215. The rotation of the first threaded tube 215 causes the sleeve 214 to move linearly. The displacement of the sleeve 214 pushes the follower guide wheel 218 by pushing the connecting frame 216 and the central shaft 219. The displacement of the follower guide wheel 218 pushes the swing plate 203, which then swings around the fixed column 204. The swing of the swing plate 203 pushes the movable shaft 211 to move horizontally. The displacement of the movable shaft 211 pushes the movable plate 201 to move horizontally by pushing the placement frame 209. The displacement of the movable plate 201 pushes the fixed block 235 to move and disengage from the mounting hole 12. At this point, the support plate 11 on one side is no longer fixed, and the operator can then disassemble the support plate 11 on one side, the movable frame 10, and the filter screen 9.

[0042] When it is necessary to disassemble the support plates 11 on both sides simultaneously, first ensure that the guide plate 213 is aligned with the guide groove 7, and then turn the two sets of second handles 224. The rotation of the second handles 224 will drive the second threaded tube 231 to rotate. The rotation of the second threaded tube 231 will drive the moving plate 226 to move longitudinally. The displacement of the moving plate 226 will drive the roller 232 to move longitudinally by pushing the support column 233. The displacement of the roller 232 will drive the protrusion 230 to move horizontally. The displacement of the protrusion 230 will drive the circumferential linkage by pushing the linkage switching push block 227. When sleeve 228 moves horizontally, the circumferential linkage sleeve 228 will engage with the outer side of the first locking block 223. When the first handle 212 on one side is turned, the rotation of the first threaded tube 215 will drive the first locking block 223 to rotate by driving the rotating column 217. The rotation of the first locking block 223 will drive the reference linkage shaft 202 to rotate by driving the circumferential linkage sleeve 228. The rotation of the reference linkage shaft 202 will drive the other set of first threaded tubes 215 to rotate. Thus, the two sets of movable plates 201 can move synchronously, and then the support plates 11 on both sides can be disassembled.

[0043] When installing the support plate 11, movable frame 10, and filter screen 9, first turn the second handle 224 to rotate the second threaded tube 231, causing the circumferential linkage sleeve 228 to shift and engage with the outside of the first locking block 223. Then turn the first handle 212 to rotate the first threaded tube 215. The rotation of the first threaded tube 215 drives the first locking block 223 to rotate via the rotating column 217. The rotation of the first locking block 223 drives the reference linkage shaft 202 to rotate via the circumferential linkage sleeve 228. The rotation of the reference linkage shaft 202 drives the other set of first threaded tubes 215 to rotate. This allows the two sets of movable plates 201 to move synchronously. Then, the movable frame 10 and filter screen 9 are installed. The mesh 9 and support plate 11 are inserted into the filter box 8. At this time, the mounting hole 12 and the fixing block 235 are parallel. The first threaded tube 215 is reversed to make the sleeve 214 move back. The movement of the sleeve 214 will push the follower guide wheel 218 back by pushing the connecting frame 216 and the central shaft 219. At this time, the follower guide wheel 218 no longer pushes the swing plate 203. Then, the first spring 207 will bounce the movable plate 201 back by bouncing the slider 205 back. The movement of the movable plate 201 will bounce the fixing block 235 into the mounting hole 12. At this time, the support plate 11 will be fixed in the filter box 8 by the fixing block 235, thus completing the installation of the support plate 11, the movable frame 10 and the filter mesh 9.

[0044] When it is necessary to remove the movable frame 10 and the filter screen 9 from the support plate 11, push the toggle block 304 to make it push the parallel plate 305 to move horizontally. The displacement of the parallel plate 305 will push the mounting plate 303 to move horizontally and disengage from the slot 13. At this time, the mounting plate 303 no longer fixes the movable frame 10, and then the operator can easily remove the single set of movable frame 10 and filter screen 9.

[0045] When installing the movable frame 10 and the filter screen 9, push the actuating block 304 to move the parallel plate 305 horizontally. The displacement of the parallel plate 305 will push the mounting plate 303 horizontally. At this time, the parallel plate 305 will squeeze the third spring 302, and then the movable frame 10 will be inserted into the outer side of the parallel plate 305 and the mounting plate 303. At this time, the mounting plate 303 and the slot 13 are parallel. Then release the actuating block 304. At this time, the third spring 302 will bounce the parallel plate 305 back. The back movement of the parallel plate 305 will bounce the mounting plate 303 back. The back movement of the mounting plate 303 will be inserted into the slot 13. At this time, the mounting plate 303 will fix the filter screen 9 by locking the movable frame 10. Thus, the movable frame 10 and the filter screen 9 are installed on the support plate 11, and the installation of the movable frame 10 and the filter screen 9 is completed.
