Detailed Implementation

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Please see Figures 1 to 5This utility model provides a technical solution: a flow-through sterilizer, including a flow-through pipe 1, with a detection port 14 centrally located at the top of the flow-through pipe 1. An opening / closing assembly 10 is provided on the side of the detection port 14, including an arc-shaped cover plate 101 located behind the detection port 14. A front mounting plate 105 is fixedly connected to the side of the detection port 14, and a rear mounting plate 104 is fixedly connected to the side of the arc-shaped cover plate 101. A support rod 106 is rotatably connected between the front mounting plate 105 and the rear mounting plate 104. A first support plate 102 is fixedly connected to the outer side of the arc-shaped cover plate 101. The flow pipe 1 is internally screwed with a first fixing bolt 103. A second support plate 12 is fixedly connected to the front side of the detection port 14. The second support plate 12 has a threaded hole 13 inside, through which the first fixing bolt 103 is screwed. A sealing strip 11 is fixedly connected to the inner side of the detection port 14 and to the outer side of the arc-shaped cover plate 101. Two limiting rings 16 are fixedly connected inside the flow pipe 1. A reflective sleeve 9 is fixedly connected between the two limiting rings 16. The outer side of the reflective sleeve 9 is in close contact with the inner wall of the flow pipe 1, and an ultraviolet lamp is installed inside the reflective sleeve 9. When it is necessary to perform inspection or maintenance operations on the inside of the flow pipe 1, the operator loosens the first fixing bolt 103, causing the first fixing bolt 103 to disengage from the threaded hole 13 on the second support plate 12, thereby releasing the fixing restriction on the arc-shaped cover plate 101. Since the front mounting plate 105 and the rear mounting plate 104 are rotatably connected by the support rod 106, the arc-shaped cover plate 101 can rotate around the support rod 106 as an axis, thereby opening the arc-shaped cover plate 101 and exposing the detection port 14. This facilitates the operation of personnel to inspect and maintain the internal structure and equipment status of the flow pipe 1. After the operation is completed, the arc-shaped cover plate 101 is rotated back to its original position, so that the arc-shaped cover plate 101 is in close contact with the detection port 14. At this time, the sealing strip 11 on the inner side of the arc-shaped cover plate 101 and the detection port 14 are in close contact. The elastic deformation of the sealing strip 11 fills the gap and enhances the sealing effect. Then, the first fixing bolt 103 is passed through the first support plate 102 and screwed into the threaded hole 13. The first fixing bolt 103 is tightened so that the arc-shaped cover plate 101 is firmly fixed at the detection port 14, preventing liquid from leaking from the detection port 14 and ensuring the sealing and safety of the flow sterilizer during operation.

[0024] like Figures 1 to 5As shown, an end cap 17 is provided on the left side of the flow pipe 1. Multiple second fixing bolts 18 are screwed through the inner side of the end cap 17. The second fixing bolts 18 are screwed to the side of the flow pipe 1. A top post 15 is fixedly connected to the inner side of the end cap 17. The right end of the top post 15 is fixedly installed on the side of the limiting fixing ring 16. A protruding tube 19 is provided on the right side of the flow pipe 1. The protruding tube 19 is connected to the inner side of the flow pipe 1. An inlet 7 and a drain 6 are fixedly connected to the top left and right sides of the flow pipe 1, respectively. A flange 8 is fixedly connected to the top of both the inlet 7 and the drain 6. A support leg bracket 5 is fixedly connected to the bottom of the flow pipe 1. There are two support leg brackets 5. A control box 4 is fixedly connected to the side of the two support leg brackets 5. A display screen 2 and a control button 3 are fixedly connected to the side of the control box 4. The display screen 2 is located to the left of the control button 3. The liquid to be disinfected enters the flow pipe 1 through the inlet 7 and flange 8. Since the inlet 7 and outlet 6 are located on the left and right sides of the top of the flow pipe 1 respectively, the liquid flows in a specific direction within the flow pipe 1. Inside the flow pipe 1, the reflective sleeve 9 and its internal ultraviolet lamp play a crucial disinfection role. The outer side of the reflective sleeve 9 is tightly attached to the inner wall of the flow pipe 1, and it is secured by two limiting and fixing rings 16. The top post 15 on the inner side of the end cap 17 further stabilizes the limiting and fixing rings 16, ensuring the stability of the reflective sleeve 9 and the ultraviolet lamp during operation. The ultraviolet rays emitted by the ultraviolet lamp are reflected by the reflective sleeve 9, allowing them to evenly irradiate the liquid inside the flow pipe 1. The bactericidal properties of ultraviolet light are used to disinfect the liquid, effectively killing bacteria, viruses, and other microorganisms. The disinfected liquid flows out through the outlet 6 and flange 8, completing the entire disinfection process. During equipment operation, the support legs 5 provide stable support for the flow pipe 1. The control boxes 4 installed on the sides of the two support legs 5 are used to control the operation of the equipment. Operators can start and stop the equipment and adjust the working parameters of the ultraviolet lamp through the control buttons 3. At the same time, the display screen 2 displays the operating status and working parameters of the equipment in real time, which facilitates the operator to monitor and manage the operation of the equipment and ensures the stable and efficient operation of the flow sterilizer.

[0025] Working Principle: First, the operator observes the initial status parameters of the equipment displayed on the screen 2 of the control box 4. After confirming that everything is correct, the operator starts the equipment via the control button 3 and sets the power and irradiation duration of the ultraviolet lamps on the control box 4 according to factors such as the type, flow rate, and degree of contamination of the liquid to be disinfected. After setting, the liquid to be disinfected flows steadily into the flow pipe 1 through the flange 8 at the top of the inlet 7 at a specific flow rate and direction, forming an orderly laminar or turbulent flow state within the pipe, ensuring that the liquid can fully contact the ultraviolet irradiation area. At this time, the ultraviolet lamp located inside the reflective sleeve 9 starts working according to the set parameters, emitting ultraviolet rays with bactericidal effect. These ultraviolet rays are reflected multiple times on the smooth inner wall surface of the reflective sleeve 9, evenly covering the entire liquid flow channel in the flow pipe 1. The ultraviolet rays destroy the DNA or RNA structure of bacteria, viruses, and other microorganisms, causing them to lose their ability to reproduce and infect, thereby achieving the purpose of efficient disinfection. After disinfection, the liquid continues to flow along the flow pipe 1 and flows out of the equipment from the flange 8 at the top of the drain outlet 6, entering subsequent use or treatment stages. During equipment operation, the display screen 2 continuously updates and displays the equipment's operating status in real time, including key parameters such as the actual working power of the ultraviolet lamp, the real-time flow rate, pressure, and temperature of the liquid in the flow pipe 1. This facilitates operators in monitoring the equipment's operation in real time and promptly identifying and handling any abnormalities. When the equipment needs internal inspection and maintenance after running for a period of time, the operator first turns off the equipment power. After the equipment has completely stopped running and the internal liquid has been drained, the operator loosens the first fixing bolt 103, disengaging it from the threaded hole 13 on the second support plate 12. Then, using the support rod 106 as the rotation axis, the arc-shaped cover plate 101 is rotated backward around the detection port 14 to fully expose the detection port 14. This allows staff to conduct comprehensive inspection, cleaning, repair, or replacement of components such as the ultraviolet lamp and reflective sleeve 9 inside the flow pipe 1. After completing the inspection and maintenance work, rotate the arc-shaped cover plate 101 back to its original position so that it fits tightly against the inspection port 14. At this time, the sealing strip 11 on the inner side of the arc-shaped cover plate 101 and the inspection port 14 undergoes elastic deformation due to mutual compression, fully filling the tiny gap between them and further enhancing the sealing effect. Then, pass the first fixing bolt 103 through the first support plate 102 and accurately screw it into the threaded hole 13. Tighten the first fixing bolt 103 to firmly fix the arc-shaped cover plate 101 at the inspection port 14, preventing liquid leakage and ensuring that the equipment returns to normal operation so that the liquid disinfection work can continue.
