Description

Technical Field

[0001] This utility model relates to the field of wastewater advanced treatment technology, specifically a multi-stage wastewater advanced treatment tank. Background Technology

[0002] Advanced wastewater treatment refers to the further water treatment process that follows primary and secondary treatment of urban sewage or industrial wastewater, aiming to meet certain reuse standards and allow the wastewater to be reused as a water resource for production or daily life. Depending on the quality requirements of the raw wastewater and the treated water, tertiary or multi-stage treatment processes can be employed to achieve the corresponding water use standards.

[0003] The prior art, disclosed in CN221917577U, provides a multi-stage sewage treatment device for water conservancy projects. It addresses the problem that after sewage is filtered through a filter screen, impurities remain on the screen and slide out of the container along a slope. However, some impurities become stuck on the screen, making collection difficult. The proposed solution includes a treatment box with a treatment motor fixedly installed on its top. An adsorption plate is located inside the box, and a first waterproof seat is fixedly installed on the top of the adsorption plate. A vibration mechanism, including a drive component and a striking component, is mounted on the first waterproof seat. A second waterproof seat is fixedly installed on the bottom of the adsorption plate. This invention has a simple structure and can strike the filter screen, causing vibration and allowing impurities on the screen to slide into the collection box for easy collection and user convenience.

[0004] In the aforementioned patent, the main method involves using a driving component to drive a striking component to strike the filter screen, thereby sending impurities from the filter screen into the collection box. However, this method of striking the filter screen results in impurities located at the edges of the filter screen holes not being sent into the collection box, causing impurities to accumulate inside the filter screen holes. This affects the filtration effect of the wastewater and greatly reduces the practicality of the multi-stage wastewater treatment device. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-stage wastewater deep treatment tank, thus solving the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage wastewater treatment tank, comprising a filtration tank, a chemical dosing tank, and a sedimentation tank, including a protective shell. A chemical dosing port is provided through the end of the protective shell away from the ground. An inlet is fixedly installed on one side of the protective shell, and an outlet is fixedly installed on the side of the protective shell away from the inlet. The inlet is located on the sedimentation tank side, and the outlet is located on the filtration tank side. A filter assembly is fixedly installed on the top of the filtration tank on the protective shell. The protective shell includes a first pump body and a second pump body for liquid flow in each tank. The filter assembly includes a hollow limiting body and a filter element. The outlet of the second pump body is located within the hollow limiting body, and the filter element is located at the end of the hollow limiting body away from the second pump body. A striking component and a cleaning component are rotatably mounted on the protective shell. The striking component is used to strike the filter element, and the cleaning component is used to clean the filter holes within the filter element. The cleaning component is used to clean the filter holes inside the filter component, thereby allowing the filter component in the multi-stage wastewater treatment tank to perform long-term filtration operations and extending the service life of the internal structure of the multi-stage wastewater treatment tank.

[0007] Furthermore, the filter component includes a filter plate for wastewater filtration. A penetrating shaft is installed through the filter plate on the side near the striking assembly. Connecting strips are fixedly installed at both ends of the penetrating shaft. Telescopic shafts are fixedly installed on both sides of the end of the penetrating shaft near the second pump body. The end of the telescopic shaft away from the penetrating shaft is fixedly installed on the protective shell. A fixed shaft is fixedly installed between an even number of connecting strips. The fixed shaft between an even number of connecting strips makes the internal structure of the multi-stage wastewater treatment tank more robust and reliable, greatly improving the operational safety of the multi-stage wastewater treatment tank.

[0008] Furthermore, the cleaning component includes a bidirectional motor, which is fixedly mounted on the outside of the protective shell. A drive shaft is fixedly mounted on the output end of the bidirectional motor, and a connecting block is fixedly mounted on the drive shaft. A swing plate is fixedly mounted on the side of the connecting block near the hollow limiting body. Several cleaning protrusions are fixedly mounted on the side of the swing plate near the filter plate, and these protrusions are used to insert into the filter holes of the filter plate. This allows the bidirectional motor to swing the swing plate in both forward and reverse directions, greatly improving the operational versatility of the internal structure of the multi-stage wastewater treatment tank.

[0009] Furthermore, the striking assembly includes a motor, which is fixedly mounted on the outside of the protective shell. A rotating shaft is fixedly mounted on the output end of the motor, and a cam is fixedly mounted on the rotating shaft. The cam is located directly below the fixed shaft. The cam's position directly below the fixed shaft allows it to move the fixed shaft up and down directly when rotating, improving the overall integrity of the multi-stage wastewater treatment tank's internal structure.

[0010] Furthermore, the protective shell has a cylindrical groove directly below the filter plate outlet. A spring is fixedly installed inside the cylindrical groove, and a fixing block is fixedly installed at the top of the spring. The end of the fixing block away from the spring is fixed to the bottom of the filter plate. This fixing of the end of the fixing block away from the spring allows the spring to amplify the shaking when the filter plate vibrates, improving the practicality of the multi-stage wastewater treatment tank.

[0011] Furthermore, the hollow limiting body is a hollow right-angled trapezoid with its inclined surface close to the ground. This design allows for controlled flow of wastewater as it enters the hollow limiting body, significantly improving the controllability of the wastewater flow direction within the multi-stage wastewater treatment tank's internal structure.

[0012] Furthermore, the filter plate is convex in shape and installed parallel to the inclined surface of the hollow limiting body. This convex shape and parallel installation allows water flowing downwards from the hollow limiting body to be effectively filtered through the filter plate, greatly improving the practicality of the multi-stage wastewater treatment tank. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention uses a hammering component to continuously hammer the inclined filter component, and in conjunction with several rotating cleaning protrusions inserted from bottom to top into the filter holes of the filter plate, so that impurities on the filter plate can be effectively discharged from the filter plate, greatly improving the practicality of multi-stage wastewater deep treatment tanks.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0023] Example

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6This application provides a further detailed description. A multi-stage wastewater treatment tank includes a filtration tank 2, a chemical dosing tank 3, and a sedimentation tank 4. It also includes a protective shell 6. A chemical dosing port 8 is provided at one end of the protective shell 6 away from the ground. An inlet 5 is fixedly installed on one side of the protective shell 6, and an outlet 1 is fixedly installed on the side of the protective shell 6 away from the inlet 5. The inlet 5 is located on one side of the sedimentation tank 4, and the outlet 1 is located on one side of the filtration tank 2. A filter assembly 7 is fixedly installed at the top of the filtration tank 2 on the protective shell 6. The protective shell 6 includes a first pump body 61 and a second pump body 62 for liquid flow between the tanks. The filter assembly 7 includes a hollow limiting body 72 and a filter element 73. The outlet of the second pump body 62... The water inlet is located inside the hollow limiting body 72. The filter component 73 is located at the end of the hollow limiting body 72 away from the second pump body 62. A striking component 71 and a cleaning component 74 are rotatably mounted on the protective shell 6. The striking component 71 is used to strike the filter component 73, and the cleaning component 74 is used to clean the filter holes inside the filter component 73. The filter component 73 includes a filter plate 731 for filtering sewage. A penetrating shaft 735 is installed through the filter plate 731 on the side near the striking component 71. Connecting strips 733 are fixedly installed at both ends of the penetrating shaft 735. Telescopic shafts 734 are fixedly installed on both sides of the end of the penetrating shaft 735 near the second pump body 62. The telescopic shafts 734 are located away from the penetrating component 735. One end of shaft 735 is fixedly mounted on protective shell 6. A fixed shaft 732 is fixedly mounted between an even number of connecting strips 733. The cleaning component 74 includes a bidirectional motor 741, which is fixedly mounted on the outside of protective shell 6. A drive shaft 742 is fixedly mounted on the output end of the bidirectional motor 741. A connecting block 743 is fixedly mounted on the drive shaft 742. A swing plate 744 is fixedly mounted on the side of the connecting block 743 near the hollow limiting body 72. Several cleaning protrusions 745 are fixedly mounted on the side of the swing plate 744 near the filter plate 731. The cleaning protrusions 745 are used to insert into the filter holes of the filter plate 731. The striking component 71 includes a motor 711. The motor 711 is fixedly installed on the outside of the protective shell 6. A rotating shaft 712 is fixedly installed on the output end of the motor 711. A cam 713 is fixedly installed on the rotating shaft 712. The cam 713 is located directly below the fixed shaft 732. A cylindrical groove is opened directly below the outlet of the filter plate 731 in the protective shell 6. A spring 76 is fixedly installed inside the cylindrical groove in the protective shell 6. A fixing block 75 is fixedly installed on the top of the spring 76. The end of the fixing block 75 away from the spring 76 is fixed to the bottom of the filter plate 731. The hollow limiting body 72 is a hollow right-angled trapezoid with its inclined surface close to the ground. The filter plate 731 is convex and is installed parallel to the inclined surface of the hollow limiting body 72.

[0025] Since the plane area of ​​the filter plate 731 is larger than the plane area of ​​the entire hollow limiting body 72, when the sewage flows downward from the hollow limiting body 72, it can be completely filtered through the filter plate 731. The filtered water flows downward through the filter holes on the filter plate, while the impurities remain directly on the filter plate 731.

[0026] Because the inlet 5 is connected to a filter container with a large filter hole, when sewage enters the multi-stage sewage treatment tank from the inlet 5, larger solid impurities will be directly left in the filter container, which greatly improves the quality of sewage purification in the multi-stage sewage treatment tank.

[0027] Since the number and position of the cleaning protrusions 745 correspond one-to-one with the number and position of the filter holes in the filter plate 731, when the bidirectional motor 741 swings the cleaning protrusions 745, the cleaning protrusions 745 will directly push the impurities in the filter holes in the filter plate upward. Combined with the shaking force of the cam 713 hitting the filter plate 731, the impurities are effectively cleaned out of the multi-stage sewage deep treatment tank.

[0028] The working principle of this utility model is explained below: Unless otherwise specified, all mechanical structures inside the multi-stage wastewater treatment tank are threaded. To allow for a more intuitive observation of the technical features, bolt connections are appropriately concealed in the diagram. During use, the user feeds the wastewater to be filtered into the inlet 5. Inlet 5 will initially filter the wastewater. After sedimentation in the sedimentation tank 4, the user starts the first pump 61, which directly pumps the wastewater from the sedimentation tank 4 into the chemical dosing tank 3. The user then adds chemicals into the chemical dosing tank 3 through the dosing port 8. After the wastewater and chemicals have completely reacted, the second pump 62 pumps the wastewater downwards through the hollow limiting body 72, which acts as a limiting element. The filter plate 731 then performs the final filtration of the incoming wastewater. The purified water directly enters the filtration tank 2 and finally flows through… The wastewater is discharged outward through outlet 1. When the user needs to clean the impurities on the filter plate 731, they only need to start the motor 711 and the bidirectional motor 741. The started motor 711 will directly rotate the cam 713, which will move the fixed shaft 732 up and down. The fixed shaft 732 will move the penetrating shaft 735 up and down. At this time, the telescopic shaft 734 will extend and retract. During the up and down movement, the filter plate 731 will hit the hollow limit body 72. At the same time, the spring 76 will elastically extend and retract. The rotating bidirectional motor 741 will swing the swing plate 744, causing the cleaning protrusion 745 to be inserted into the filter hole in the filter plate 731. This will move the impurities in the filter hole to the filter plate 731. Since the filter plate 731 is in an inclined state, the continuously shaking filter plate 731 will effectively send the impurities above it out of the multi-stage sewage treatment tank, which greatly improves the cleaning quality of the internal filter plate 731 of the multi-stage sewage treatment tank.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
