Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a graded wastewater treatment device. Background Technology

[0002] A graded wastewater treatment system is a water treatment system designed based on the concept of "differentiated treatment and graded purification." Its principle is to divide the entire treatment process into multiple functionally defined stages or units according to the nature, concentration, and treatment difficulty of pollutants in the wastewater. Each unit specifically removes specific types or concentration ranges of pollutants, ultimately achieving the expected water quality standards for the effluent. A graded wastewater treatment system typically consists of an anaerobic tank, an aerobic tank, a sedimentation tank, a disinfection tank, and an equipment room. During operation, wastewater first enters the anaerobic tank, where anaerobic bacteria decompose large organic molecules. It then enters the aerobic tank, where an aeration system supplies oxygen, and aerobic microorganisms degrade organic matter and complete nitrification. The mixed liquor undergoes solid-liquid separation in the sedimentation tank, sludge is returned to maintain microbial concentration, and the clear water flows into the disinfection tank, where chemicals or ultraviolet light are used to kill pathogenic microorganisms. The PLC control cabinet, blowers, and other devices in the equipment room ensure automatic operation of each stage, ultimately ensuring that the wastewater meets discharge standards. Because the wastewater treatment equipment needs to be connected to external pipelines to ensure the wastewater enters the system, protective measures are necessary.

[0003] In related technologies, during the use of sewage treatment equipment, the sewage treatment equipment is generally connected to the external sewage pipeline through the flange reserved in the sewage treatment equipment, so that external sewage can enter the sewage treatment equipment for use.

[0004] However, in the current use of sewage treatment equipment, because the flanges used for connection are located on the outside, as the working time increases, external rainwater and other dirt come into direct contact with the flange connection, causing corrosion and rust at the connection flange of the sewage treatment equipment, resulting in leakage at the connection flange and affecting the protective and stable sewage treatment connection of the sewage treatment equipment.

[0030] Reference Figures 1-4 This utility model provides a technical solution: a graded sewage treatment equipment, including a sewage treatment machine 1 and a treatment protection mechanism. The sewage treatment machine 1 is equipped with a treatment tank 2 inside. A connector 3 is installed on the top left side of the sewage treatment machine 1. A clamping and surrounding protective medium can be formed between the connector 3 and the external sewage pipeline, so that the user can protect the connection between the connector 3 and the external sewage pipeline. Therefore, the sewage treatment connection protection and stability of the sewage treatment machine 1 and the connector 3 are improved.

A protective pad 5 is fixedly connected to the inner side of the protective frame 4. A protective cover 6 is movably connected to the top of the protective frame 4. A protective plate 7 is movably connected inside the protective cover 6. A protective connection mechanism is fixedly connected to both sides of the inner top of the protective frame 4. When the protective frame 4 is moved to the outside of the connection point between the connector 3 and the external sewage pipe, and the protective plate 7 is moved downward to cooperate with the protective cover 6, a clamping force is applied between the protective frames 4. At the same time, the inner side of the protective pad 5 contacts the surface of the protective head, stabilizing the protective frame 4. The outer side of connector 3 is protected at the connection point between connector 3 and external sewage pipe. The protective connection mechanism includes connector 8, connector 9 and connecting rod 10. Connector 8 is fixedly connected to both sides of the inner top of protective frame 4. Connector 9 is opened inside connector 8. Connecting rod 10 is movably connected inside connector 9. The outer side of connecting rod 10 passes through protective cover 6, which can perform translational connection between protective cover 6 and protective frame 4. This allows users to adjust the position of protective frame 4 according to the actual use needs of connector 3, thus improving the protective connection effect between protective frame 4 and protective cover 6.

[0032] Reference Figures 2-3In a preferred embodiment, springs 11 are fitted on both sides of the connecting rod 10. One end of the spring 11 is connected to the inner wall of the protective cover 6, and the other end of the spring 11 is connected to the surface of the connecting seat 8. The connecting seat 8 can cooperate with the connecting rod 10 to apply an inward pushing force to the protective frame 4, thus improving the ease of installation of the pre-clamping of the protective frame 4. A screw groove 12 is provided on the outer side of the connecting rod 10. The screw groove 12 is threaded with a bolt 13 located on the outer side of the protective cover 6, which can stably connect the connecting rod 10 and the protective cover 6, thus improving the connection stability between the connecting rod 10 and the protective cover 6.

[0033] Reference Figures 2-4 In a preferred embodiment, by fixing a screw cylinder 14 to the top of the protective cover 6 and movably connecting a stud 15 threadedly connected to the screw cylinder 14 to the top of the protective plate 7, a medium can be provided for the user to apply a clamping force to the protective plate 7, thus improving the ease of clamping the protective plate 7. The top of the protective plate 7 is provided with a movable groove 16, and the bottom of the stud 15 is fixedly connected to a movable seat 17 located inside the movable groove 16, which can perform connection and anti-separation work between the stud 15 and the protective plate 7, thus improving the connection effect between the stud 15 and the protective plate 7.

[0034] Reference Figures 2-4 In a preferred embodiment, a magnetic sheet 18 is embedded in the bottom of the movable groove 16, and a magnetic suction sheet 19, which is magnetically connected to the magnetic sheet 18, is embedded in the bottom of the movable seat 17. The stud 15 and the protective plate 7 can be magnetically positioned by the connecting seat 8, thus improving the positioning convenience of the stud 15. A rotating sleeve 20 is movably connected to the outside of the screw barrel 14. The top of the stud 15 is fixedly connected to the inner wall of the rotating sleeve 20. A rotating handle 21 is fixedly connected to the top of the rotating sleeve 20. This can surround and waterproof the screw barrel 14 and provide the user with a medium to rotate the stud 15, thus improving the protective effect and ease of use of the stud 15.

[0035] Specifically, the working process or principle of this graded sewage treatment equipment is as follows: When in use, after the connector 3 is connected to the external sewage pipe, first move the protective frame 4 to both sides to prepare for the subsequent enclosure of the protective frame 4 around the outside of the connector 3. At this time, the connecting seat 8 moves with the protective frame 4 outside the connecting rod 10. Through the screw groove 12 and the bolt 13, a translational connection is made between the protective frame 4 and the protective cover 6. Simultaneously, the spring 11 contracts under the influence of the outward movement of the connecting seat 8, preparing for the subsequent inward pushing force applied to the protective frame 4 through the connecting seat 8. Then, move the protective frame 4 to the outside of the connection point between the connector 3 and the external sewage pipe, and move the protective frame 4 downward so that the inner protective pad 5 of the protective frame 4 contacts the top of the surface of the connector 3 and the external sewage pipe. Subsequently, move the protective frame 4 inward so that the inner protective pad 5 of the protective frame 4 contacts the surface of the connector 3 and the external sewage pipe. At this time, the contracted spring 11 applies a force to the protective frame 4 through the connecting seat 8. An inward thrust is applied, causing the protective frame 4, in conjunction with the protective pad 5, to be pre-clamped on the outside of the connector 3 and the external sewage pipe. Then, through the rotating handle 21 and the rotating sleeve 20, a rotational force is applied to the stud 15, causing the stud 15 to rotate and engage with the screw barrel 14 through the movable seat 17 and the movable groove 16, applying a downward threaded thrust to the protective plate 7. This causes the bottom of the protective plate 7 to contact and abut against the top of the protective frame 4, performing a clamping and positioning operation between the protective frame 4 and the protective cover 6. This ensures that the protective frame 4 maintains a stable clamping force on the outside of the connection between the connector 3 and the external sewage pipe. At this time, the magnetic sheet 18, in conjunction with the magnetic suction sheet 19, performs a magnetic suction positioning operation between the stud 15 and the protective plate 7 through the movable seat 17. Simultaneously, the rotating sleeve 20 provides a protective sleeve between the screw barrel 14 and the stud 15, causing the protective frame 4, in conjunction with the protective cover 6 and the protective pad 5, to surround and protect the connection between the connector 3 and the external sewage pipe, ensuring the protection and stability of the sewage entering the sewage treatment machine 1 and the connector 3.

[0036] It should be noted that the sewage treatment machine 1, the treatment tank 2 and the connector 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
