Further, referring to fig. 3, 4 and 5, the lifting assembly 130 includes: the guide rail 131, the baffle 132, the first half case 133a, the second half case 133b, the center post 134, the driver 136a, and the lifter 136b.
The guide rail 131 is disposed along the height direction of the processing tank 110, and the ultraviolet light assembly 120 is slidably coupled to the guide rail 131.
The number of baffles 132 is two, and the two baffles 132 are arranged in parallel, at intervals and in parallel, and the baffles 132 are also arranged along the height direction of the treatment tank 110. There is a gap between the two baffles 132 for accommodating the first half shell 133a, the second half shell 133b and the center post 134.
The first half shell 133a and the second half shell 133b are both circular arc-shaped in cross section, and both extend along the length direction of the baffle 132. The inner arc walls of the first half shell 133a and the second half shell 133b are arranged in opposite directions, the outer arc walls of the first half shell 133a and the second half shell 133b are provided with external threads 137, and the external threads 137 of the first half shell 133a and the second half shell 133b are matched and positioned on the same spiral line. In the width direction of the processing tank 110, both the first half case 133a and the second half case 133b are slidable with respect to the shutter 132 so that both the first half case 133a and the second half case 133b can be moved toward and away from each other. The uv assembly 120 is provided with internal threads for mating with external threads 137 of both the first half-shell 133a and the second half-shell 133 b.
The center post 134 is disposed between the first half shell 133a and the second half shell 133 b. A first connecting piece 135a is connected between the first half shell 133a and the center column 134, and two ends of the first connecting piece 135a are respectively hinged with the first half shell 133a and the center column 134. A second connecting piece 135b is connected between the second half shell 133b and the center column 134, and two ends of the second connecting piece 135b are respectively hinged with the second half shell 133b and the center column 134. The rotational axes of the hinge portions of the first and second links 135a and 135b are disposed perpendicular to the baffle 132.
The center post 134 penetrates the top wall of the processing tank 110 and is driven by a driver 136a, and after the driver 136a drives the center post 134 to rotate, the center post 134 can drive the baffle 132, the first half shell 133a and the second half shell 133b to rotate together, so that the external threads 137 of the first half shell 133a and the second half shell 133b are operated, and the ultraviolet light assembly 120 can be driven to move along the guide rail 131.
The driver 136a is mounted on a lifting portion of the lifter 136b, and the lifter 136b is mounted on the top of the processing tank 110 to lift or lower the driver 136a along the axial direction of the center column 134, i.e., to control the driver 136a to move in the height direction of the processing tank 110. When the driver 136a is lowered to move the center column 134 into the processing tank 110 and the first and second connectors 135a and 135b are perpendicular to the center column 134, the first and second half- shells 133a and 133b are smoothly pushed away from each other, and at this time, the external threads 137 of the first and second half- shells 133a and 133b just mate with the internal threads of the uv module 120, and the driver 136a drives the center column 134, so that the uv module 120 can be driven.
When the lifter 136b lifts the driver 136a, the driver 136a pulls the center post 134 upward, and the center post 134 pulls the first and second connectors 135a and 135b upward, so that the first and second half- shells 133a and 133b are close to each other, and the external threads 137 of both the first and second half- shells 133a and 133b are separated from the internal threads of the uv assembly 120, so that the uv assembly 120 cannot be driven even if the center post 134 rotates.
Through the design, the ultraviolet light assembly 120 can be driven along the guide rail 131, the ultraviolet light assembly 120 is driven to the bottom end of the guide rail 131, then the driver 136a is lifted by the lifter 136b, the transmission matching relationship between the first half shell 133a and the second half shell 133b and the ultraviolet light assembly 120 is released, and at the moment, the ultraviolet light assembly 120 returns to the upper end of the guide rail 131 along the guide rail 131 under the buoyancy of sewage. This achieves a reciprocating motion of the ultraviolet light assembly 120. In the process of floating the ultraviolet light assembly 120, the driver 136a can be temporarily stopped, and then started when the ultraviolet light assembly 120 needs to be re-driven to the bottom end of the guide rail 131, so that more energy is saved.
The ultraviolet light assembly 120 performs reciprocating motion along the height direction of the treatment tank 110 and is also beneficial to improving the treatment effect on sewage, so that ultraviolet light can more fully irradiate sewage in the whole treatment tank 110 and simultaneously agitate the sewage, thereby avoiding the problem of insufficient local irradiation.
The lift assembly 130 may be provided with a PLC control assembly for controlling the operation of the driver 136a and the lifter 136b.
In order to enable the first and second half cases 133a and 133b to be driven more smoothly by the center post 134, both side edges of both the first and second half cases 133a and 133b are provided with extension plates 135c, the extension plates 135c are attached to the surfaces of the baffle plates 132, and the first and second connection members 135a and 135b are hinged to the extension plates 135c of both the first and second half cases 133a and 133 b. In this way, the first and second half cases 133a and 133b can be more easily slid along the barrier 135c.
In this embodiment, please refer to fig. 6 and 7, the uv light assembly 120 includes a structural body 122 and lamps 123, the structural body 122 is in a ring shape, the internal threads of the uv light assembly 120 are disposed on the inner annular wall of the structural body 122, and the lamps 123 are disposed along the radial direction of the structural body 122 and are disposed at uniform intervals along the circumferential direction of the structural body 122.
In order to make the ultraviolet light assembly 120 float more smoothly, the lamps 123 of the ultraviolet light assembly 120 are covered with a colorless transparent lamp cover 121, the colorless transparent lamp cover 121 is waterproof, and the inner diameter of the colorless transparent lamp cover 121 is greater than or equal to 5 times of the outer diameter of the lamps 123 of the ultraviolet light assembly 120.
Each lamp tube 123 is covered with a colorless transparent lamp shade 121, and the connection part of the colorless transparent lamp shade 121 and the structural body 122 is subjected to waterproof treatment. The central axis of the lamp tube 123 is arranged to coincide with the central axis of the colorless transparent lamp shade 121.
In this way, a greater buoyancy force can be provided for the ultraviolet light assembly 120, so that the ultraviolet light assembly 120 can float upwards and reset smoothly. In addition, the colorless transparent lampshade 121 can effectively increase the irradiation range of ultraviolet rays of the lamp tube 123 and improve the photosensitive area of sewage, so that the treatment effect and the treatment efficiency of ultraviolet light on afternoon nap are further improved.
Further, in the present embodiment, the first connectors 135a and the second connectors 135b are disposed at uniform intervals along the length direction of the center column 134, and the first connectors 135a and the second connectors 135b are alternately disposed.
