[0004] In view of the above related technologies, when the existing organic carbon digestion device for ultrapure water preparation is working, since the ultraviolet lamp tube rotatably arranged inside the cylinder body emits light and generates heat, the heat generated by the ultraviolet lamp tube will be transferred to the water body to heat the water body, which easily causes the water temperature to rise during the preparation of ultrapure water and affects the normal progress of the subsequent filtration process.

The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0032] Next, according to the overall structure of the present invention, its embodiments will be described.

[0033] Embodiment 1

[0034] An organic carbon digestion device for ultrapure water preparation, as Figures 1-8 shown, includes a cylinder body 1. Specifically, the bottom end of the cylinder body 1 is connected to a base 13, and the two ends of the top are respectively connected to a water inlet and a water outlet. The two ends of the cylinder body 1 are open and the cross-section is annular. One end of the cylinder body 1 is connected to a sealing cover 3, and a hollow glass column 2 is inserted inside. One end of the cylinder body 1 away from the sealing cover 3 is tightly connected to the glass column 2. An ultraviolet lamp tube assembly is rotatably connected inside the glass column 2, and a ventilation tube 5 is arranged along the axial direction. The outer wall of the ventilation tube 5 is fixedly connected to the ultraviolet lamp tube assembly. One end of the ventilation tube 5 away from the sealing cover 3 is connected to an axial blowing assembly. A ring of blades 11 is arranged at one end of the inner wall of the ventilation tube 5 close to the sealing cover 3. The airflow along the axis of the ventilation tube 5 can make the ventilation tube 5 rotate.

[0035] Please refer to Figures 4-8 , a first fixing cylinder 6 and a second fixing cylinder 7 are respectively rotatably connected to the inner wall of the glass column 2 at both ends of the ventilation tube 5. The first fixing cylinder 6 is away from the sealing cover 3, and a fan 10 that blows air towards the second fixing cylinder 7 is arranged inside. The first fixing cylinder 6 and the second fixing cylinder 7 are used to support the rotation of the ventilation tube 5, so that the ventilation tube 5 is kept at the center position of the glass column 2 and is parallel to the axis of the glass column 2. The airflow generated by the fan 10 working in the second fixing cylinder 7 flows along the ventilation tube 5 and then blows the blades on the inner wall of the ventilation tube 5, providing power for the rotation of the ventilation tube 5. The airflow passing through the ventilation tube 5 and the second fixing cylinder 7 flows out of the glass column 2 in the opposite direction between the outer wall of the ventilation tube 5 and the inner wall of the glass column 2, and takes away the heat generated by the ultraviolet lamp tube 9 during operation during the flowing process. The diameters of the first fixing cylinder 6 and the second fixing cylinder 7 are smaller than that of the ventilation tube 5, and the outer walls of the ends are in contact with the inner wall of the ventilation tube 5, further improving the ability of the first fixing cylinder 6 and the second fixing cylinder 7 to stably support the ventilation tube 5.

[0036] Please refer toFigures 2-8 , an annular flange is provided at one end of the glass column 2 away from the sealing cover 3. A pressing ring 4 is connected to one end of the cylinder body 1. The pressing ring 4 presses the flange of the sealing cover 3 against the end of the cylinder body 1, and the glass column 2 is pressed by the pressing ring 4. Specifically, annular sealing washers are provided between the edge of the glass column 2, the pressing ring 4 and the cylinder body 1. The annular sealing washers can further improve the sealing performance between the cylinder body 1 and the glass column 2, and effectively avoid the phenomenon of water leakage between the glass column 2 and the cylinder body 1 on the premise that the ultraviolet lamp tube assembly rotates.

[0037] Please refer to Figures 4-8 , a light shielding plate 12 is fixedly connected to the outer wall of one end of the first fixed cylinder 6 away from the ventilation cylinder 5. The diameter of the light shielding plate 12 is larger than the diameter of the glass column 2 and does not contact the glass column 2. The light shielding plate 12 can block most of the light emitted by the ultraviolet lamp tube 9, playing a role in protecting the staff. The air flow flowing in the opposite direction along the outer wall of the ventilation cylinder 5 and the inner wall of the glass column 2 flows out between the light shielding plate 12 and the glass column 2. One end of the glass column 2 close to the sealing cover 3 is of a hemispherical structure, and the sealing cover 3 is also of a hemispherical structure. The outer wall of the end of the glass column 2 can fit with the inner wall of the hemispherical sealing cover 3, so that the sealing cover 3 plays a role in supporting the end of the glass column 2. Specifically, after the hemispherical sealing cover 3 is connected to the cylinder body 1, it protrudes along the axis direction of the cylinder body 1. At this time, the glass column 2 is inserted into the cylinder body 1, and the hemispherical end of the glass column 2 contacts the inner wall of the sealing cover 3, so that the sealing cover 3 plays a role in supporting the glass column 2, and the hemispherical glass column 2 can also make the gas blown out from the second fixed cylinder 7 evenly dispersed, effectively improving the cooling effect of the ultraviolet light in the glass column 2.

[0038] Embodiment 2

[0039] An organic carbon digestion device for ultra-pure water preparation, as Figures 1-8 shown, on the basis of Embodiment 1, the difference from Embodiment 1 is that a plurality of rotating frames 8 are fixedly connected to the outer wall of the ventilation cylinder 5 along the length direction. An ultraviolet lamp tube 9 parallel to the axis of the ventilation cylinder 5 is connected between the plurality of rotating frames 8. The rotating frames 8 are used to support and install a plurality of ultraviolet lamp tubes 9, so that they can rotate inside the glass column 2, realizing uniform irradiation of the water body between the glass column 2 and the cylinder body 1, and effectively improving the irradiation uniformity of the ultraviolet lamp tube 9.

[0040] The working principle of the present utility model is as follows: The fan 10 operates to generate an air flow in the axial direction of the ventilation cylinder 5. This air flow blows to the blade 11 along the axial direction of the ventilation cylinder 5, causing the ventilation cylinder 5 to rotate relative to the first fixed cylinder 6 and the second fixed cylinder 7. The ultraviolet lamp tube assembly fixedly connected to the outer wall of the ventilation cylinder 5 rotates synchronously, and the ultraviolet light irradiates the water body inside the cylinder body 1 after passing through the glass column 2. Since one end of the cylinder body 1 is connected to the sealing end cover and the other end is tightly connected to the edge of the glass column 2, the sealing performance of the cylinder body 1 is effectively improved on the premise of realizing uniform irradiation of ultraviolet light.

[0041] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and not limitations thereof. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions, and variations that do not contribute creatively to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
