Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an ultraviolet disinfection device for wastewater treatment. Background Technology

[0002] Wastewater treatment refers to the process of purifying water by using various technologies and methods to separate, remove, recycle, or transform pollutants contained in wastewater into harmless substances. Ultraviolet disinfection is an effective wastewater treatment method that can effectively kill bacteria, viruses, and other microorganisms, enabling wastewater to meet safe discharge standards.

[0003] Patent CN212954414U discloses an ultraviolet disinfection device for sewage treatment. It includes a pool body with a top cover. Positioning posts are installed at the four corners of the bottom of the top cover, and a first strong magnet is installed at the bottom of each positioning post. Positioning holes are provided at the four corners of the top of the pool body, and a second strong magnet is installed in each positioning hole. This device solves the problems of existing ultraviolet disinfection devices for sewage treatment, such as inconvenience in repairing or replacing the ultraviolet lamps and poor protection against ultraviolet light. This invention effectively protects the ultraviolet lamps, facilitates repair or replacement, and is highly practical.

[0004] However, this device uses an immersion disinfection method. Although the ultraviolet lamp and the transparent protective cover are both located inside the sewage, it is difficult to guarantee that bacteria in all parts of the sewage in the pool are disinfected. At the same time, when the sewage is injected into the pool, dirt will gradually adhere to the surface of the transparent protective cover, reducing the disinfection effect of the ultraviolet lamp. These two factors seriously affect the disinfection and treatment of sewage. Therefore, an ultraviolet disinfection device for sewage treatment is proposed to solve the problem that existing sewage disinfection devices cannot stably and fully kill bacteria.

[0015] (III) Beneficial Effects

[0016] 1. This ultraviolet disinfection equipment for sewage treatment introduces the sewage to be disinfected into the main body of the equipment through the inlet pipe. At the same time, the ultraviolet lamps are turned on, allowing the sewage to flow through the surface of three inclined guide plates and be disinfected by ultraviolet radiation. This not only increases the area of ​​the sewage exposed to ultraviolet radiation, but also prevents the ultraviolet lamps from coming into contact with the sewage and being attached to dirt, thus ensuring the disinfection effect and solving the problem that existing sewage disinfection equipment is difficult to stably and fully kill bacteria.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figure 1-4 An ultraviolet disinfection device for sewage treatment includes a disinfection device body 1, a sealing door 2 on one side of the disinfection device body 1, a water inlet pipe 3 at the upper position of one end of the disinfection device body 1, a liquid separation mechanism 4 on the inner wall of the disinfection device body 1, a drain pipe 5 at the lower position of one end of the disinfection device body 1, three guide plates 6 fixedly connected to the inner cavity of the disinfection device body 1, three mounting brackets 7 slidably arranged in the inner cavity of the disinfection device body 1, ultraviolet lamp tubes 8 arranged in the inner cavity of the mounting brackets 7, sealing plates 9 at both ends of the disinfection device body 1, and fixing plates 10 fixedly connected to both ends of the disinfection device body 1, with limit pins 11 symmetrically arranged on the top of the fixing plates 10.

[0025] Furthermore, all three guide vanes 6 are inclined, and the upper and lower guide vanes 6 are centrally symmetrically distributed.

[0026] Furthermore, the mounting bracket 7 is parallel to the guide plate 6 at the corresponding position at the bottom, and the mounting bracket 7 passes through the main body 1 of the disinfection equipment and is fixedly connected to the sealing plate 9.

[0027] Furthermore, when the ultraviolet lamp 8 is completely located inside the cavity of the main body 1 of the disinfection equipment, the sealing plate 9 and the fixing plate 10 are attached, and the limiting pin 11 penetrates the fixing plate 10 to the inner wall of the sealing plate 9. The limiting pin 11 and the sealing plate 9 can slide but are not connected. When the ultraviolet lamp 8 needs to be disassembled and repaired after a long period of operation, the symmetrical limiting pins 11 on the top of the fixing plate 10 can be removed, and then the sealing plate 9 and the fixing plate 10 can be separated. Then the mounting bracket 7 along with the ultraviolet lamp 8 can be taken out from the inside of the main body 1 of the disinfection equipment, which facilitates the disassembly, repair and installation of the ultraviolet lamp 8.

[0028] Furthermore, the liquid separation mechanism 4 includes a liquid separation tank 401 formed in the inner wall of the disinfection equipment body 1. The inner cavity of the liquid separation tank 401 is provided with a liquid separation shell 402. The liquid separation shell 402 is fixedly connected with three inclined liquid separation plates 403. The liquid separation tank 401 is interconnected with the inner cavity of the disinfection equipment body 1, and the water inlet pipe 3 is interconnected with the inner cavity of the liquid separation shell 402. When sewage is introduced from the water inlet pipe 3, the sewage will first enter the liquid separation shell 402 in the liquid separation tank 401 and be separated by the liquid separation plates 403. This allows the sewage introduced from the water inlet pipe 3 to be quickly dispersed and flow through the surface of the top guide plate 6, thereby ensuring the contact area between the sewage and ultraviolet light and improving the sewage disinfection effect.

[0029] Furthermore, one end of the sealing door 2 is connected to the main body 1 of the disinfection equipment via a hinge, and the other end of the sealing door 2 is connected to the main body 1 of the disinfection equipment via a latch 13.

[0030] Furthermore, a viewing window 12 is provided on one side of the sealed door 2, and a sealing groove 14 is provided on one side of the main body 1 of the disinfection equipment. A sealing strip 15 is provided in the inner cavity of the sealing groove 14. The sealing strip 15 is fixedly connected to the sealed door 2. The internal sewage flow can be observed through the viewing window 12. When a lot of dirt accumulates on the guide plate 6, the latch 13 is opened and the sealing door 2 is opened with the hinge, so that the inside of the main body 1 of the disinfection equipment and the guide plate 6 can be cleaned, which improves the convenience of disassembly, maintenance and cleaning of the disinfection equipment. During the process of cleaning and closing the sealed door 2, the sealing strip 15 on the sealed door 2 enters the sealing groove 14 to improve the sealing performance of the disinfection equipment, ensure the stability of the sewage treatment process and avoid sewage leakage and pollution.

[0031] Working principle: When using this ultraviolet disinfection equipment for sewage treatment, the sewage to be disinfected is introduced into the main body 1 of the disinfection equipment through the inlet pipe 3. At the same time, the ultraviolet lamps 8 are turned on, so that the sewage flows through the surface of the three inclined guide plates 6 and is disinfected by ultraviolet irradiation. This not only increases the area of ​​sewage irradiated by ultraviolet light, but also prevents the ultraviolet lamps 8 from coming into contact with sewage and being attached to dirt, thus ensuring the sewage disinfection effect and solving the problem that existing sewage disinfection equipment is difficult to stably and fully kill bacteria. When the ultraviolet lamps 8 need to be disassembled and repaired after a long period of operation, the symmetrical limiting pins 11 on the top of the fixing plate 10 can be removed, and then the sealing plate 9 can be separated from the fixing plate 10. The mounting bracket 7 along with the ultraviolet lamps 8 can then be taken out from the inside of the disinfection equipment main body 1, which facilitates the disassembly, repair and installation of the ultraviolet lamps 8.
