Under the action of a multi-layer filtering device, the final clean water is discharged from the bottom of the base. However, when the above-mentioned technical solution is used to add a reaction liquid, such as a flocculant, the flocculant can only be added to the surface of the sewage. Even if there is a stirring device for stirring, there is still a problem of slow mixing efficiency. Utility Model Content

[0023] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a sewage treatment tank for sewage treatment equipment of the present invention in conjunction with the accompanying drawings.

[0024] See also Figure 1-5 The utility model is a sewage treatment tank for sewage treatment equipment, comprising a treatment cylinder 1, a support plate 2 being fixedly connected to the top of the treatment cylinder 1, a stepping motor 3 being arranged above the support plate 2, a rotating shaft 5 being fixedly connected to the output end of the stepping motor 3, a long plate 8 being fixedly connected to the outer surface of the rotating shaft 5, a rectangular block 6 being fixedly connected to the outer surface of the treatment cylinder 1, four groups of supporting legs 7 being fixedly connected to the bottom surface of the rectangular block 6, and the rectangular blocks 6 and the supporting legs 7 being arranged, and the supporting legs 7 being utilized to provide supporting force for the device, making the device stand more stably.

[0025] The inner wall of the long plate 8 is fixedly connected to the circular cylinder 10, the inner bottom wall of the circular cylinder 10 is fixedly connected to the top shaft 20, the bottom end of the treatment cylinder 1 is fixedly connected to the discharge pipe 12, and the outer surface of the discharge pipe 12 is fixedly connected to the solenoid valve 11. By providing the discharge pipe 12 and the solenoid valve 11, the solenoid valve 11 can control the discharge pipe 12 to discharge the liquid inside the treatment cylinder 1, thereby achieving a better auxiliary effect.

[0026] Six groups of extrusion nozzles 19 are fixedly connected to the inner wall of the circular cylinder 10, and a limiting groove 26 is provided at the top of the circular cylinder 10. The inner sliding connection of the limiting groove 26 is connected to the limiting block 27, and the outer surface of the limiting block 27 is fixedly connected to the extrusion plate 16. The inner part of the extrusion plate 16 is clamped with a blocking block 17, and the upper surface of the blocking block 17 and the upper surface of the extrusion plate 16 are jointly fixedly connected to the limiting rope 18. The inner wall of the processing cylinder 1 is fixedly connected to the gear ring 9, and the outer surface of the stepping motor 3 is fixedly connected to the fixing seat 4, and the bottom surface of the fixing seat 4 is fixedly connected to the upper surface of the support plate 2. By providing the fixing seat 4, the fixing seat 4 can provide support force for the stepping motor 3, so that the stepping motor 3 can run more stably.

[0027] The outer surface of the gear ring 9 is meshed with a gear 15, and the inner wall of the gear 15 is fixedly connected to a threaded shaft 14. The outer surface of the threaded shaft 14 is rotatably connected to the inner wall of the circular cylinder 10 and the inner wall of the long plate 8 respectively. The inner wall of the long plate 8 is provided with two sliding grooves 21, and the interior of each sliding groove 21 is slidably connected to a sliding block 25. The side of the two sliding blocks 25 close to each other is jointly fixedly connected to the cleaning plate 13. By providing the sliding groove 21, the sliding block 25 and the cleaning plate 13, the cleaning plate 13 can be driven away from or close to the inner wall of the processing cylinder 1 by utilizing the connection relationship of the sliding block 25 sliding inside the sliding groove 21, thereby determining whether the inner wall of the processing cylinder 1 is to be cleaned.

[0028] The outer surface of the threaded shaft 14 is threadedly connected to the inner wall of the extrusion plate 16, and the upper surface of the cleaning plate 13 is fixedly connected to a connecting plate 22. The inner wall of the connecting plate 22 is fixedly connected to two limit shafts 23. Two groups of limit openings 24 are opened on the upper surface of the long plate 8. The outer surfaces of the two limit shafts 23 are respectively engaged with the inner parts of two of the limit openings 24. By providing the connecting plate 22, the limit shaft 23 and the limit opening 24, and utilizing the engaging relationship between the limit opening 24 and the limit shaft 23, the long plate 8 and the cleaning plate 13 can be fixed in two different positions, ensuring that the cleaning plate 13 will not move away from the inner wall of the processing cylinder 1 due to external force when working.

[0029] The working principle of the present invention is as follows: first, when the present device needs to be used, the blocking block 17 can be pulled out, and then the flocculant can be placed inside the circular cylinder 10. The multiple extrusion nozzles 19 fixed on the inner wall of the circular cylinder 10 will not open when they are not squeezed, so there is no need to worry about the flocculant overflowing. Subsequently, the blocking block 17 is reset, and then the stepper motor 3 is controlled to operate. The power generated when the stepper motor 3 is running can drive the rotating shaft 5 to rotate. By utilizing the transmission characteristics of the rotating shaft 5, the power generated when the stepper motor 3 is running can be transmitted to the long plate 8, thereby driving the long plate 8 to rotate inside the treatment cylinder 1. Since the circular cylinder 10 is fixed to the inner wall of the long plate 8, when the long plate 8 rotates, the circular cylinder 10 and the threaded shaft 14 connected to the inner wall of the circular cylinder 10 will also rotate around the rotating shaft 5. When the threaded shaft 14 rotates, the gear 15 fixed on the outer surface will rotate under the action of the gear ring 9, so it can The gear 15 and the threaded shaft 14 fixed on the inner wall of the gear 15 are driven to rotate around their own center of circle, and the threaded connection relationship between the extrusion plate 16 and the threaded shaft 14 is coordinated to push the extrusion plate 16 downward, and the limit block 27 fixed on the outer surface of the extrusion plate 16 slides inside the limit groove 26, thereby preventing the extrusion plate 16 from rotating. During the descending process, the extrusion plate 16 will squeeze the flocculant inside the circular cylinder 10. At this time, the extrusion nozzle 19 will discharge the flocculant into the sewage when it is subjected to the extrusion force. In addition, when the extrusion plate 16 descends to the bottom, the top shaft 20 will push the blocking block 17 open, so that the space above the extrusion plate 16 will be connected with the space below, ensuring that the sewage inside the treatment cylinder 1 will not flow back into the interior of the circular cylinder 10 due to the action of air pressure during the resetting of the extrusion plate 16, thereby effectively preventing the flocculant from being sprayed only on the surface of the sewage, resulting in low mixing efficiency.
