Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Fig. 1 is a schematic perspective view of an ultraviolet sterilizing and purifying apparatus for a drain-vent pipe according to an embodiment of the present utility model; fig. 2 is a schematic structural view of an outer tub of an ultraviolet sterilizing and purifying device for a drain-vent pipe according to an embodiment of the present utility model; fig. 3 is a schematic structural view of an inner support ring of an ultraviolet sterilizing and purifying device for a drain-vent pipe according to an embodiment of the present utility model; fig. 4 is a cross-sectional view along A-A of fig. 1.

Referring to the drawings, the ultraviolet sterilizing and purifying device for a drain-vent pipe of the embodiment may include an outer tub (10), an inner support ring (20), a plurality of quartz sleeves (30), a plurality of ultraviolet lamps (40), and an electric heating jacket (not shown) disposed at the outer circumference of the outer tub.

Referring to fig. 1 and 2, the outer cylinder (10) includes a main body (12), two flanges (11) fixed to both ends of the main body, and two connection mechanisms (14) fixed to the two flanges. The two connection means (14) may be secured to a drain breather pipe (not shown) respectively, as shown, the connection means (14) may be, for example, a connection flange. The diameter of the flange plate (11) is equal to the diameter of the main body (12), and the bore diameter of the flange plate is smaller than the diameter of the main body (12). As shown in the figure, a plurality of through holes (13) are formed in the flange (11) for fixing the plurality of quartz sleeves (30). The body (12), the flange (11) and the connecting means (14) can be fixed together by welding, for example.

Referring to fig. 1 and 4, the quartz sleeve (30) may be a hollow quartz tube whose cross section is formed to coincide with the through hole. The quartz sleeve (30) passes through the corresponding through holes on the two flanges, and the outer side walls of the two ends are respectively and hermetically fixed on the inner walls of the through holes. Thus, the gas in the outer cylinder (10) does not leak through the through hole (13).

In order to stabilize the quartz sleeve (30) more, an inner support ring (20) can also be arranged inside the main body (12) for fixedly supporting the quartz sleeve (30). A securing washer (not shown) may also be provided between the securing ring (22) and the quartz sleeve for a secure setting of the quartz sleeve. As shown in fig. 1 and 3, the inner support ring (20) includes a main ring (21) and a plurality of fixing rings (22) fixedly provided along the outer circumference of the main ring, 8 being shown, and a specific number may be set according to the number of quartz sleeves (30). The inner support ring (20) is fixedly connected with the inner wall of the outer cylinder (10) through a plurality of fixing rings (22); the fixing ring (22) may be fixed to the main ring (21) by welding, for example, to form the inner support ring (20), and then fixed to the inner wall of the main body (12) by welding. The number of the inner support rings (20) may be set as required, although 1 is shown in the figure.

The ultraviolet lamp (40) may be placed therein through an opening at both ends or one end of the quartz sleeve, for example, the ultraviolet lamp (40) may be provided in a long cylindrical shape with a diameter smaller than that of the quartz sleeve. After placement, the attachment may be by means such as adhesive, snap fit, or gasket. The quartz sleeve is made of transparent quartz, so that ultraviolet light can penetrate, and the disinfection effect of the ultraviolet light is not affected. The number of the ultraviolet lamps (40) can be set according to actual needs, such as required power and the like.

Considering that most bacteria and viruses are sensitive to temperature, an electric heating sleeve can be additionally arranged on the periphery of a drainage breather pipe or an outer cylinder (10) of the device, so that the gas can be deeply disinfected, namely high-temperature sterilization. The electric heating sleeve can be selectively configured according to the requirements.

The internal structure of the utility model is optimized, which not only improves the efficiency of ultraviolet disinfection and purification (for example, the internal space of the device is larger than the drainage breather pipe, so that the gas flow speed from the drainage breather pipe is slowed down and turbulent flow occurs in the internal space, and better disinfection effect can be realized), but also is more convenient for maintenance and replacement (for example, the ultraviolet lamp is arranged outside the device, so that the replacement is convenient), the occupied area is small, and the engineering design and the practical installation are convenient. The ultraviolet rays and the high Wen Shuangchong are used for sterilization, so that the infectivity of the gas viruses in the drainage breather pipe is ensured to be minimized, and the secondary transmission of the gas aerosol viruses can be effectively prevented.

The foregoing is merely a preferred embodiment of the present patent, and it should be noted that modifications could be made by those skilled in the art without departing from the scope of the present patent, and such modifications should also be considered as being within the scope of the present patent.
