Description

Technical Field

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

[0002] Wastewater treatment typically involves processes such as filtration, flocculation, sterilization, and disinfection to enable wastewater to be reused.

[0003] Chinese patent document CN222138793U discloses a disinfection device for sewage treatment, including a treatment tank and a disinfection drive assembly. The disinfection drive assembly includes a drive motor, a linkage plate, and a fixing rod. The drive motor is installed on one side of the outer surface of the treatment tank. A connecting frame is fixedly connected to one side of the inner wall of the treatment tank. A rotating rod is rotatably connected inside the connecting frame. One end of the rotating rod is fixedly connected to the output end of the drive motor, and the other end is fixedly connected to one side of the linkage plate. The linkage plate is located outside the connecting frame. A linkage rod is rotatably connected to one end of the linkage plate. The linkage rod is located inside the treatment tank. A fixing sleeve is fixedly connected to one end of the linkage rod. The fixing rod is located inside the treatment tank, and a connecting ball is installed at one end of the fixing rod. The connecting ball is located inside the fixing sleeve and rolls with it.

[0004] However, when using the above method, the screw rod is pulled to rotate the thread of the screw rod in the threaded hole of the threaded block, so that the screw rod drives the longitudinal stirring blades to stir the sewage. But directly pulling the screw rod to rotate the thread in the threaded hole results in a large friction between the thread and the inner wall of the threaded hole, which makes the rotation speed of the screw rod low, resulting in poor sewage stirring effect and poor mixing effect between sewage and agent.

[0031] Example 1

[0032] like Figure 1-5 As shown, the present invention proposes a disinfection device for sewage treatment, comprising a treatment tank 1, a conveying pipe 2, a holding cylinder 9, a dispensing component, and a driving component;

[0033] The conveying pipe 2 is installed inside the treatment tank 1. The inside of the conveying pipe 2 is equipped with a conveying component for circulating the sewage inside the treatment tank 1 in the conveying pipe 2 under disinfection conditions.

[0034] The dispensing component is installed at the top of one end of the conveying pipe 2 and is connected to the conveying pipe 2; the holding cylinder 9 is installed at the top of the dispensing component;

[0035] The drive component is mounted on the side of the dispensing component and engages with the top of the dispensing component.

[0036] In this embodiment, the drive component drives the dispensing component to rotate, causing the dispensing component to intermittently dispense the disinfectant inside the container 9 into the conveying pipe 2. At the same time, the conveying component rotates inside the conveying pipe 2, causing the conveying component to transport the disinfectant from one end of the conveying pipe 2 along the length of the conveying pipe 2 to the other end of the conveying pipe 2. Simultaneously, the conveying component drives the sewage and disinfectant inside the treatment tank 1 to move synchronously, so that the sewage inside the treatment tank 1 flows into the conveying pipe 2 in sequence and is discharged into the inside of the treatment tank 1. The sewage and disinfectant inside the treatment tank 1 circulate through the cooperation of the conveying pipe 2 and the conveying component, which improves the uniformity of mixing between sewage and disinfectant and improves the sewage disinfection efficiency.

[0037] Example 2

[0038] like Figure 1-3 As shown, the present invention proposes a disinfection device for sewage treatment. Compared with the first embodiment, the difference in this embodiment is that the conveying component includes a spiral plate 3, a first motor 4, and a rotating shaft 5.

[0039] The rotating shaft 5 is located inside the conveying pipe 2, and both ends extend toward the inner wall of the processing box 1 and are rotatably mounted on the processing box 1. The rotating shaft 5 is coaxially arranged with the conveying pipe 2.

[0040] The spiral plate 3 is installed on the outside of the rotating shaft 5 and located on the inside of the conveying pipe 2;

[0041] The first motor 4 is located on the outside of the processing box 1 and is connected to the rotating shaft 5 for transmission.

[0042] In this embodiment, the first motor 4 drives the rotating shaft 5 to rotate, which in turn drives the spiral plate 3 to rotate inside the conveying pipe 2. This causes the spiral plate 3 to generate a suction force on the inside of the conveying pipe 2 towards one end of the pipe. The spiral plate 3 then moves the medicine and sewage inside the conveying pipe 2 towards one end of the pipe, and the sewage at one end of the treatment tank 1 is conveyed from the inside of the conveying pipe 2 to the other end of the treatment tank 1. This allows the sewage inside the treatment tank 1 to circulate, improving the mixing effect between the sewage and the medicine and increasing the sewage treatment efficiency.

[0043] Example 3

[0044] like Figure 3 As shown, the present invention proposes a disinfection device for sewage treatment. Compared with the first embodiment, the difference in this embodiment is that notches 12 are provided at the bottom of both ends of the conveying pipe 2 and at the inner wall of the treatment tank 1, and multiple through holes 13 are provided on the outer circular surface of the conveying pipe 2 near the middle. A branch pipe 6 extending to the top of the treatment tank 1 is provided at the top of one end of the conveying pipe 2 above the notch 12.

[0045] In this embodiment, the notch 12 allows the spiral plate 3 to drive the sewage from one end of the treatment tank 1 to the other end of the treatment tank 1 from the inside of the conveying pipe 2. At the same time, the sewage in the middle of the treatment tank 1 is discharged to the other end of the treatment tank 1 through the through hole 13, thereby increasing the sewage flow speed and increasing the mixing speed of sewage and reagent.

[0046] Example 4

[0047] like Figure 4-5 As shown, the present invention proposes a disinfection device for sewage treatment. Compared with the first embodiment, the difference in this embodiment is that the dispensing component includes a connecting cap 7 and a receiving tray 8.

[0048] The connecting cap 7 is installed at the top of the branch pipe 6 and communicates with the branch pipe 6, and its top is connected to the holding cylinder 9;

[0049] The receiving tray 8 is rotatably installed between the connecting cap 7 and the holding cylinder 9 and is engaged with the drive assembly.

[0050] In an optional embodiment, the end of the receiving tray 8 is provided with a plurality of cavities 16 arranged at equal angles around the center of the receiving tray 8, and a feeding hole 15 is provided on the upper end surface of the connecting cap 7 and in the moving path of the cavity 16. The feeding hole 15 and the cavity 16 have the same size.

[0051] In an optional embodiment, mounting grooves 18 are provided at the bottom edge of the container 9 and the top edge of the connecting cap 7, and protruding rings 17 are provided at the top and bottom edges of the receiving tray 8. When the receiving tray 8 is installed in conjunction with the connecting cap 7 and the container 9, the protruding rings 17 are fitted and accommodated in the mounting grooves 18, so that the receiving tray 8, the branch pipe 6 and the container 9 have a sealing effect when the protruding rings 17 and the mounting grooves 18 are engaged during use.

[0052] In this embodiment, the agent in the holding cylinder 9 is held in multiple cavities 16, and the receiving plate 8 is driven to rotate between the connecting cap 7 and the holding cylinder 9 by the driving component. This allows the multiple cavities 16 to sequentially add the agent into the sewage through the feeding hole 15. When the sewage circulates inside the conveying pipe 2, it carries the agent and increases the agent placement area, thereby increasing the mixing speed of the agent and the sewage and improving the sewage disinfection efficiency.

[0053] Example 5

[0054] like Figure 4 As shown, the present invention proposes a disinfection device for sewage treatment. Compared with the first embodiment, the difference in this embodiment is that the driving component includes a second motor 10 and a gear 11.

[0055] The second motor 10 is mounted on the side of the connecting cap 7 and its output shaft extends to the side of the receiving tray 8;

[0056] Gear 11 is mounted on the output shaft of the second motor 10 and meshes with the receiving disc 8.

[0057] In an optional embodiment, the outer side of the middle portion of the receiving tray 8 is provided with teeth 14, and when the receiving tray 8 and the gear 11 are installed together, the gear 11 and the teeth 14 are meshed together.

[0058] In this embodiment, the second motor 10 drives the gear 11 to rotate. The gear 11 drives the receiving plate 8 to rotate between the connecting cap 7 and the holding cylinder 9 through the engagement of the teeth 14. This causes multiple cavities 16 to be arranged coaxially with the feeding hole 15 in sequence, so that the medicine inside the cavity 16 is fed into the sewage through the feeding hole 15.

[0059] In summary, in this utility model, the first motor 4 drives the rotating shaft 5 to rotate, which in turn drives the spiral plate 3 to rotate inside the conveying pipe 2. The spiral plate 3 generates a suction force on the inside of the conveying pipe 2 towards one end of the conveying pipe 2. Through the cooperation of the notch 12 and the through hole 13, the sewage in the middle and one end of the inner side of the treatment tank 1 is conveyed to the other end of the inner side of the treatment tank 1, so that the sewage inside the treatment tank 1 circulates. At the same time, the agent in the holding cylinder 9 is held by multiple cavities 16. The second motor 10 drives the gear 11 to rotate. The gear 11 drives the receiving plate 8 to rotate between the connecting cap 7 and the holding cylinder 9 through the cooperation of the teeth 14. The multiple cavities 16 are arranged coaxially with the feeding hole 15 in sequence, so that the agent inside the multiple cavities 16 is intermittently added to the flowing sewage through the feeding hole 15, thereby increasing the agent placement area. At the same time, the sewage circulation improves the mixing efficiency of sewage and disinfectant, and also improves the sewage disinfection efficiency.

[0060] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
