Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an environmentally friendly ultraviolet sterilizer for wastewater treatment. Background Technology

[0002] Ultraviolet (UV) sterilizers for environmental wastewater treatment are devices that use ultraviolet radiation to kill bacteria, viruses, and other pathogenic microorganisms in water. These UV sterilizers are commonly used in wastewater treatment plants, drinking water treatment, swimming pool treatment, and other environments to ensure that water quality meets relevant standards and protect human health and the environment.

[0003] In existing ultraviolet (UV) sterilizers for wastewater treatment, although the water to be sterilized is simply filtered and purified, it still contains impurities such as scale and dust. After prolonged use, these impurities accumulate on the inner wall of the sterilizer shell. Since the sterilizer shell is generally a tubular structure with sealed ends, it is difficult to clean the impurities accumulated on the inner wall of the UV sterilizer shell. Therefore, we propose an environmentally friendly UV sterilizer for wastewater treatment. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide an environmentally friendly ultraviolet sterilizer for wastewater treatment, so as to solve the technical problem that it is difficult to clean the impurities accumulated on the inner wall of the shell of the current ultraviolet sterilizer.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] An environmentally friendly ultraviolet sterilizer for wastewater treatment includes a sterilizer housing, which is detachable. A lamp holder is installed inside the sterilizer housing. The lamp holder is electrically connected to a power switch via a wire. An ultraviolet lamp is installed inside the lamp holder and is electrically connected to the lamp holder. A protective cover is fitted over the ultraviolet lamp.

[0008] A movable rod is installed inside the sterilizer housing. A scraper is fixedly installed at one end of the movable rod, and the scraper can move along the axial direction of the sterilizer housing via the movable rod to clean impurities on the inner wall of the sterilizer housing.

[0009] As an improved technical solution, the protective cover is provided with a plurality of through holes, which are evenly arranged along the axial and / or circumferential direction of the protective cover.

[0010] Alternatively, the protective cover may be a cylindrical mesh shell structure.

[0011] As an improved technical solution, the sterilizer housing includes a sterilizer base and a sealing cover. The sealing cover is installed on the sterilizer base by a sealing ring. The scraper is slidably installed in the inner cavity of the sterilizer base. The moving rod passes through the sealing cover and is installed on the sealing cover by a rubber ring, and the rubber ring is fixedly installed on the sealing cover.

[0012] One end of the sterilizer base is provided with a threaded groove, and the sealing cover has an integrally formed threaded interface corresponding to the threaded groove. The threaded interface is adapted to the threaded groove, and the sealing ring is sleeved and installed on the outer surface of the threaded interface. The sealing cover is installed on one end of the sterilizer base through the threaded interface, the threaded interface and the sealing ring threadedly engaged and sealed.

[0013] As an improved technical solution, the top of the sterilizer base is equipped with an inlet and an outlet, and both the inlet and the outlet are connected to the inner cavity of the sterilizer base. The inlet and the outlet are symmetrically arranged along the axial direction of the sterilizer base.

[0014] As an improved technical solution, the top of the sterilizer base has an integrally formed convex box, and the convex box is connected to the inner cavity of the sterilizer base. The convex box is located inside the water inlet and the water outlet, and the lamp holder is installed on the top wall of the inner cavity of the convex box.

[0015] As an improved technical solution, a fixed support is fixedly installed at the bottom of the sterilizer base, and the fixed support is symmetrically arranged along the axial direction of the sterilizer base.

[0016] As an improved technical solution, the outer surface of the sealing cover is provided with a plurality of anti-slip textures, and the plurality of anti-slip textures are equidistantly arranged along the axial or circumferential direction of the sealing cover.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are:

[0018] 1. This utility model involves applying a pulling force to a moving rod, which drives a scraper to move along the inner wall of the sterilizer substrate towards the sealing cover until the scraper has cleaned all impurities from the inner wall of the sterilizer substrate. Then, the sealing cover is rotated, causing the threaded interface to move threadedly within the threaded groove and away from the threaded groove until it is disassembled, cleaned, and then reset. This facilitates the cleaning of impurities from the inner wall of the sterilizer shell, and the operation is simple and quick.

[0019] 2. In this utility model, when the power switch is turned on, the ultraviolet lamp emits ultraviolet light due to the power supply. When the ultraviolet light irradiates the microorganisms in the sewage, it will destroy their DNA and RNA structure, causing them to lose their biological activity, thereby achieving the purpose of sterilization and disinfection. After a period of time, the ultraviolet lamp can be turned off by using the power switch, thus making it convenient to disinfect and sterilize sewage. Attached Figure Description
