[0031] The top surface of the cavity 101 is set to be open, and a top 102 is detachably installed at the open part of the cavity 101. A servo motor 7 is set in the middle of the top cover 102. The output end of the servo motor 7 is fixed with an active rotating shaft 81 through a coupling. The active rotating shaft 81 extends into the cavity 101. An active gear disk 91 is set on the upper part of the active rotating shaft 81, and a stirring paddle 11 is symmetrically arranged on the outer side of the active rotating shaft 81.

[0036] With this design, the ultraviolet lamp tube 10 is arranged in an eight-shaped inclined manner by setting the inclined surface block 5. Compared with the ultraviolet lamp tube 10 arranged vertically, the ultraviolet lamp tube 10 arranged in an eight-shaped inclined manner can increase the scattering range of ultraviolet rays and improve energy efficiency.

[0037] The inner wall of the cavity 101 is symmetrically provided with slots 14, and an inverted U-shaped piece 15 is inserted in the slot 14.

[0039] With this design, by setting the connecting plate 171 to have an arc-shaped cross section, compared with a straight plate design, it can better fit the outer wall of the ultraviolet lamp tube 10, thereby increasing the contact area between the bristles 172 and the outer wall of the ultraviolet lamp tube 10, thereby better facilitating the subsequent cleaning of the dirt on the outer wall of the ultraviolet lamp tube 10 by the bristles 172;

[0041] With this design, the bracket 13 provided with the second bearing 62 is firstly arranged in the middle of the bottom end surface of the cavity 101, and the active rotating shaft 81 is inserted into the second bearing 62, so that the stability of the active rotating shaft 81 during rotation can be improved, and spline grooves are respectively provided in the second bearing 62, and a spline portion is provided under the active rotating shaft 81, and the spline portion of the active rotating shaft 81 and the spline groove provided in the second bearing 62 are mutually adapted, so that it is convenient for the operator to disassemble and assemble the active rotating shaft 81, and it is easy to maintain and clean it later;

[0042] Embodiment 1

[0043] First, the sewage to be sterilized is injected into the cavity 101 through the liquid inlet 1011, and then the operator turns on the power of the ultraviolet lamp 10 through the controller 18, so that the ultraviolet lamp 10 irradiates and disinfects the water in the cavity 101;

[0044] The controller 18 enables the servo motor 7 to drive the active rotating shaft 81 and the active gear plate 91 and the stirring paddle 11 disposed outside the servo motor 7 to rotate together. The stirring paddle 11 can mix the sewage in the cavity 101 to improve the uniformity of sterilization.

[0045] When the servo motor 7 drives the active gear plate 91 on the active rotating shaft 81 to rotate, it can synchronously drive the driven gear plate 92 meshing therewith to rotate, and the ultraviolet lamp tube 10 arranged under the driven gear plate 92 rotates on its own.

[0046] Furthermore, the angle between the inclined surface of the inclined surface block 5 and the horizontal plane is 10°-35°, and the two groups of ultraviolet lamp tubes 10 are arranged in an eight-shaped inclined manner;

[0047] By providing the inclined surface block 5, the ultraviolet lamp tube 10 is arranged in an eight-shaped inclined manner. Compared with the ultraviolet lamp tube 10 arranged vertically, the ultraviolet lamp tube 10 arranged in an eight-shaped inclined manner can increase the scattering range of ultraviolet rays and improve energy efficiency.

[0048] A connecting plate 171 with bristles 172 is also provided in the cavity. The cross section of the connecting plate 171 is arc-shaped. The bristles 172 provided on one side of the connecting plate 171 and the ultraviolet lamp tube 10 are both inclined, and the bristles 172 fit the outer wall of the ultraviolet lamp tube 10.

[0049] By setting the connecting plate 171 to have an arc-shaped cross section, compared with a straight plate design, it can better fit the outer wall of the ultraviolet lamp tube 10, thereby increasing the contact area between the bristles 172 and the outer wall of the ultraviolet lamp tube 10, and thus better facilitating the subsequent cleaning of the dirt on the outer wall of the ultraviolet lamp tube 10 by the bristles 172. When the ultraviolet lamp tube 10 rotates, the bristles 172 can continuously clean it, thereby avoiding the external structure of the ultraviolet lamp tube 10 affecting the disinfection and sterilization effect;

[0050] Embodiment 2

[0051] The connecting plate 171 provided with the bristles 172 and the ultraviolet lamp tube 10 are arranged in an eight-shaped tilted manner, so that the impurities brushed off the outer wall of the ultraviolet lamp tube 10 are easy to fall to the bottom of the cavity 101, and the operator opens the solenoid valve 12 through the controller 18 to facilitate the discharge of the impurities inside from the slag discharge port 1013;

[0052] The operator can remove the top cover 102 from the open portion of the cavity 101 by opening the mutually engaged block 42 and the buckle 41. Since a spline groove is provided in the second bearing 62 on the bracket 13 and a spline portion is designed under the active rotating shaft 81, the spline portion of the active rotating shaft 81 and the spline groove provided in the second bearing 62 are mutually adapted, so that it is convenient for the operator to disassemble and assemble the active rotating shaft 81, and it is easy to maintain and clean the stirring paddle 11 later. At the same time, it is also convenient for the operator to take out the inverted U-shaped member 15 connected with the connecting plate 171 and the bristles 172 from the slot 14, so as to facilitate the replacement or cleaning of the connecting plate 171 and the bristles 172.

[0053] Furthermore, a cover plate 3 is detachably mounted on the top cover 102 by means of bolts 2, thereby facilitating the operator to disassemble or replace the ultraviolet lamp tube 10 disposed at the bottom thereof, thus providing convenience for the subsequent maintenance of the sterilization and disinfection device.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
