Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment devices, and in particular to wastewater reuse and purification devices. Background Technology

[0002] Wastewater reuse and purification systems are key equipment for solving water scarcity problems and are of great significance for achieving sustainable water resource utilization. They can efficiently purify various types of wastewater, removing pollutants and impurities through multiple advanced treatment processes, transforming it into reusable water that meets standards. These systems are widely used in industrial production, urban greening irrigation, and residential applications. They not only effectively reduce dependence on fresh water resources and lower the environmental pollution caused by wastewater discharge, but also save various industries significant water resource costs, contributing to the construction of a resource-saving and environmentally friendly society and promoting sustainable economic and social development.

[0003] Traditional wastewater reuse and purification systems have a relatively simple structure. The inlet features a simple screen composed of sparse metal strips, capable of intercepting only larger debris. Following this is a basic filter system, typically a single-layer fixed screen made of ordinary material, ineffective at filtering fine particles. The biological treatment section is a simple pool, oxygenated by simple aeration equipment, resulting in limited microbial treatment. Chemical sedimentation takes place in an open, square tank, with manual and imprecise dosing. Disinfection uses a simple chlorine tablet dosing device. The overall layout is chaotic, with haphazardly connected pipes between components, and virtually no automation, relying primarily on manual operation and monitoring.

[0004] Traditional wastewater reuse and purification devices often suffer from inconvenient filter components due to their fixed welding or one-piece installation methods, lacking easily detachable interfaces. The tight connection between the filter screen and frame, coupled with the absence of a quick-release mechanism, necessitates significant manpower and resources for cleaning or replacement. This not only impacts maintenance efficiency and increases costs but also leads to filter clogging after prolonged use, reducing filtration effectiveness and hindering the removal of impurities from wastewater. Consequently, this negatively impacts subsequent biological treatment and disinfection processes, ultimately resulting in purified water that fails to meet reuse requirements. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wastewater reuse and purification treatment device, which aims to improve the problem that the filter components of traditional wastewater reuse and purification treatment devices are inconvenient to disassemble, affecting maintenance efficiency and increasing maintenance costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wastewater reuse and purification treatment device, including a purification tank, a water pump is provided on the side wall of the purification tank, an inlet pipe is fixedly connected to the output end of the water pump, a filter assembly is provided on the side wall of the purification tank, and a drainage assembly is provided on the side wall of the purification tank.

[0007] The filtration assembly includes a filter disc disposed on the side wall of the purification tank. Multiple connecting columns are fixedly connected to the side wall of the filter disc. Multiple rotating shafts are rotatably connected to the outer wall of each connecting column. A clamping plate is fixedly connected to the side wall of each rotating shaft. Multiple fixing components are fixedly connected to the side wall of the purification tank. A fixing column is fixedly connected inside each fixing component. The clamping plate is slidably connected inside the fixing column. A spring is disposed on the side wall of the clamping plate. One end of the spring is fixedly connected to the outer wall of the connecting column, and the other end is fixedly connected to the inside of the clamping plate.

[0008] Furthermore, the drainage assembly includes a drainage pipe, which is fixedly connected to the side wall of the purification tank.

[0009] Furthermore, a drain pipe is fixedly connected to the side wall of the drainage pipe, and a connecting platform is fixedly connected to the top of the drainage pipe.

[0010] Furthermore, a rotating wheel is rotatably connected to the back of the connecting platform, and a connecting shaft is fixedly connected to the side wall of the rotating wheel. The connecting shaft is rotatably connected inside the connecting platform.

[0011] Furthermore, a gear is fixedly connected to the outer wall of the connecting shaft, and a sliding column is slidably connected inside the connecting platform.

[0012] Furthermore, a rack is fixedly connected to the side wall of the sliding column, and the rack meshes with the gear.

[0013] Furthermore, a valve wheel is fixedly connected to the bottom of the slide column, and a spring is provided at the top of the slide column.

[0014] Furthermore, one end of the second spring is fixedly connected inside the connecting platform, and the other end of the second spring is fixedly connected to the top of the sliding column.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, the clamping plate, when subjected to force, drives the rotating shaft at its bottom to rotate on the outer wall of the connecting column and change its tilt angle. During reinstallation, the tension of the clamping plate by the spring keeps its position stable, shortening the downtime for device maintenance, ensuring the continuity of purification work, avoiding the impact of long-term downtime on the amount of sewage purified, and ensuring the stable operation of the entire sewage treatment system.

[0017] In this invention, the rotating wheel, when subjected to force, drives the connecting shaft on its side wall to rotate inside the connecting platform. Finally, the spring returns it to its original position, and the water can then be discharged through the drain pipe. Efficient drainage ensures that the sewage passes through each treatment stage evenly and stably, guaranteeing the consistency of the treatment effect. This improves the stability of the purified water quality and better meets the stringent water quality requirements of different reuse scenarios. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-2 An embodiment of this utility model is provided: a wastewater reuse and purification treatment device, including a purification tank 1, a water pump 2 is provided on the side wall of the purification tank 1, an inlet pipe 3 is fixedly connected to the output end of the water pump 2, a filter assembly is provided on the side wall of the purification tank 1, and a drainage assembly is provided on the side wall of the purification tank 1.

[0025] The filtration assembly includes a filter disc 4, which is disposed on the side wall of the purification tank 1. Multiple connecting columns 5 are fixedly connected to the side wall of the filter disc 4. Multiple rotating shafts 6 are rotatably connected to the outer wall of each connecting column 5. A clamping plate 10 is fixedly connected to the side wall of each rotating shaft 6. Multiple fixing parts 8 are fixedly connected to the side wall of the purification tank 1. A fixing column 9 is fixedly connected inside each fixing part 8. The clamping plate 10 is slidably connected inside the fixing column 9. A spring 7 is provided on the side wall of the clamping plate 10. One end of the spring 7 is fixedly connected to the outer wall of the connecting column 5, and the other end of the spring 7 is fixedly connected to the inside of the clamping plate 10.

[0026] Specifically, when the filter disc 4 needs to be disassembled or reassembled, the operator presses the retaining plate 10 by hand. Under pressure, the pivot 6 at the bottom of the retaining plate 10, connected to the outer wall of the connecting column 5, begins to rotate around the connecting column 5. This rotation causes the retaining plate 10 to change its original tilt angle. As the tilt angle changes, the relative position of the retaining plate 10 and the fixing column 9 changes, allowing the retaining plate 10 to slide smoothly from inside the fixing column 9, thus releasing the lock on the filter disc 4. At this point, the filter disc 4 can be disassembled. After maintenance or replacement of the filter disc 4, and reinstallation, Spring 7 plays a crucial role, applying tension to the clamping plate 10 to ensure it adheres tightly to the fixed column 9, maintaining its stable position and thus ensuring the filter disc 4 is securely installed. This design makes the disassembly and assembly of the filter disc 4 simple and efficient, greatly reducing the downtime for maintenance. The reduced downtime ensures the continuity of the purification process and avoids a reduction in wastewater purification volume due to prolonged downtime. This plays a vital role in the stable operation of the entire wastewater treatment system, ensuring that wastewater can be continuously and effectively purified.

[0027] Reference Figure 3 The drainage assembly includes a drain pipe 11, which is fixedly connected to the side wall of the purification tank 1. A drain pipe 12 is fixedly connected to the side wall of the drain pipe 11. A connecting platform 13 is fixedly connected to the top of the drain pipe 11. A rotating wheel 14 is rotatably connected to the back of the connecting platform 13. A connecting shaft 15 is fixedly connected to the side wall of the rotating wheel 14. The connecting shaft 15 is rotatably connected inside the connecting platform 13. A gear 16 is fixedly connected to the outer wall of the connecting shaft 15. A sliding column 17 is slidably connected inside the connecting platform 13. A rack 18 is fixedly connected to the side wall of the sliding column 17. The rack 18 meshes with the gear 16. A valve wheel 20 is fixedly connected to the bottom of the sliding column 17. A second spring 19 is provided at the top of the sliding column 17. One end of the second spring 19 is fixedly connected to the inside of the connecting platform 13, and the other end of the second spring 19 is fixedly connected to the top of the sliding column 17.

[0028] Specifically, when it is necessary to discharge the purified water inside the purification tank 1, the operator manually rotates the rotating wheel 14. After the rotating wheel 14 is subjected to force, the connecting shaft 15, which is tightly connected to its side wall, begins to rotate inside the connecting platform 13. Since the connecting shaft 15 and the rotating wheel 14 are an integral structure, the rotation of the connecting shaft 15 synchronously drives the gear 16 on the outer wall of the rotating wheel 14 to rotate as well. During the rotation, the gear 16 meshes with the rack 18. Through this meshing relationship, the rotation of the gear 16 is converted into a pushing force on the rack 18. Under the action of the gear 16, the sliding column 17 on the side wall of the rack 18 is displaced in the vertical direction. When the sliding column 17 is displaced, the valve wheel 20 connected to its bottom also moves accordingly. The action of the drain pipe 11 opens or closes. After the drainage operation is completed, the spring 19 plays its role, applying elastic force to the slide column 17 and related components, causing the valve wheel 20 to reset and close the drain pipe 11. At this time, the water in the purification tank 1 is smoothly discharged through the drain pipe 12. This efficient drainage design allows the purified sewage to pass through each subsequent treatment stage evenly and stably, avoiding differences in treatment effect caused by poor drainage, ensuring the consistency of treatment effect, and thus improving the stability of the purified water quality. This allows the purified water to better meet the strict water quality requirements of different reuse scenarios, such as industrial production, landscape irrigation, and domestic miscellaneous uses.

[0029] Working principle: First, when the filter plate 4 needs to be disassembled or assembled, press the locking plate 10. After the locking plate 10 is subjected to force, it will drive the rotating shaft 6 at its bottom to rotate on the outer wall of the connecting column 5 and change its tilt angle. Then the locking plate 10 can slide from the inside of the fixed column 9 to unlock it. Then the filter plate 4 can be disassembled. When reinstalling, the tension of the locking plate 10 by the spring 7 keeps its position stable, shortens the downtime of the device for maintenance, ensures the continuity of the purification treatment work, avoids the impact of long-term downtime on the amount of sewage purified, and ensures the stable operation of the entire sewage treatment system. When it is necessary to discharge the purified water inside the purification tank 1, rotate the rotating wheel 14. After the rotating wheel 14 is subjected to force, it will drive the connecting shaft 15 on its side wall to rotate inside the connecting platform 13, and synchronously drive the gear 16 on its outer wall to rotate. The gear 16 drives the rack 18 through the meshing relationship between the gear 16 and the rack 18. The sliding column 17 on the side wall moves vertically. When the sliding column 17 moves, it can drive the valve wheel 20 at its bottom to open and close the drain pipe 11, and reset it through the spring 19. Then the water can be discharged through the drain pipe 12. Efficient drainage can make the sewage pass through each treatment stage evenly and stably, ensuring the consistency of the treatment effect, thereby improving the stability of the purified water quality and better meeting the strict requirements of water quality for different reuse scenarios.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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 make equivalent substitutions for some of the technical features.
