Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment equipment, specifically to an open channel ultraviolet disinfection device. Background Technology

[0002] Open-channel ultraviolet (UV) disinfection devices are used in wastewater treatment. These devices use multiple UV lamps to sterilize and disinfect the wastewater.

[0003] When ultraviolet (UV) lamps are immersed in sewage for extended periods, impurities easily adhere to their surface, reducing their light transmittance and consequently decreasing their effectiveness in disinfecting the sewage. Existing technologies, such as the patent application N202220448448.X, disclose an open-channel UV disinfection device. This device uses a cleaning rack with through holes for the UV lamps to pass through, and an electric push rod to move the rack from one side, scraping away impurities from the UV lamps' outer walls. However, this one-sided pushing by the electric push rod results in uneven force on the rack, causing it to tilt and potentially break the UV lamps. It also generates significant noise during operation. Furthermore, the rack needs to be kept as straight as possible, necessitating the use of a high-rigidity material, thus increasing material costs. Utility Model Content

[0058] See Figures 1 to 8This embodiment provides an open channel type ultraviolet disinfection device, including a mounting plate 10, a disinfection box 20, a cleaning frame 30, brush bristles 40, a connecting rope 50, and a drive mechanism 60.

[0059] The mounting plate 10 has multiple vertically penetrating and parallel strip-shaped mounting holes 11. Through holes 12 are formed at the four corners of the mounting plate 10, and the four through holes 12 connect to form a rectangle. Multiple disinfection boxes 20 are provided, with transparent lower ends. The lower ends of the disinfection boxes 20 pass through the corresponding strip-shaped mounting holes 11, while the upper ends of the disinfection boxes 20 remain stationary on the mounting plate 10. Each disinfection box 20 contains multiple ultraviolet lamps 21. A cleaning frame 30 is vertically movable and positioned below the mounting plate 10. Brush bristles 40 are connected to the cleaning frame 30, and multiple rows of brush bristles 40 are arranged, with one row of brush bristles 40 contacting each side of each disinfection box 20. Four connecting ropes 50 are provided, one end of which passes through the corresponding through hole 12 and connects to the cleaning frame 30. The connecting ropes 50 can be made of steel wire rope. A drive mechanism 60 is used to drive the connecting ropes 50 to raise and lower the cleaning frame 30.

[0060] In this embodiment, the cleaning frame 30 is raised and lowered by the drive mechanism 60 driving the connecting rope 50, thereby cleaning the lower end of the disinfection box 20 and ensuring that the light from the ultraviolet lamp 21 can stably penetrate the disinfection box 20 to disinfect the passing sewage. Since there are four connecting ropes 50, the cleaning frame 30 is evenly stressed when the drive mechanism 60 drives the connecting ropes 50, preventing the cleaning frame 30 from tilting and ensuring stable raising and lowering operation, thus reducing noise. The ultraviolet lamp 21 is protected inside the disinfection box 20 and is not easily damaged. Because the cleaning frame 30 is evenly stressed, its material requirements are not high; hollow or lightweight materials can be used to reduce material costs.

[0061] In one embodiment, the drive mechanism 60 includes a motor 61, a drive shaft 62, a fixed pulley 63, a first take-up pulley 64, and a second take-up pulley 65.

[0062] The motor 61 is fixedly connected to the upper surface of the mounting plate 10. The drive shaft 62 is arranged along the length of the strip-shaped mounting hole 11, rotatably mounted on the mounting plate 10, and connected to the output end of the motor 61. Four fixed pulleys 63 are provided, fixedly connected to the upper surface of the mounting plate 10, and corresponding to the through hole 12. Two first winding wheels 64 are provided, located at both ends of the drive shaft 62 and fixedly connected coaxially to it. Two second winding wheels 65 are provided, located at both ends of the drive shaft 62 and fixedly connected coaxially to it.

[0063] The first take-up reel 64 and the second take-up reel 65 on the same side are located between two fixed pulleys 63; the end of the connecting rope 50 away from the cleaning frame 30 passes around the corresponding fixed pulley 63 and is wound together with the first take-up reel 64 or the second take-up reel 65. The winding direction of the connecting rope 50 wound on the first take-up reel 64 and the second take-up reel 65 is opposite. Specifically, the first take-up reel 64 and the second take-up reel 65 on the same side are connected to their respective connecting ropes 50 and rotate, thereby winding the connecting rope 50 around themselves. Since the two connecting ropes 50 are connected to the first take-up reel 64 and the second take-up reel 65 from both sides, the drive shaft 62 rotates. When winding the connecting rope 50, one connecting rope 50 is wound clockwise on the first take-up reel 64, and the other connecting rope 50 is wound counterclockwise on the second take-up reel 65.

[0064] In this embodiment, driven by the motor 61, the drive shaft 62 rotates, causing the two first winding wheels 64 and the two second winding wheels 65 to rotate, thereby simultaneously winding or unwinding the four connecting ropes 50, which in turn drives the cleaning frame 30 to rise and fall. This configuration makes the entire device compact. Furthermore, the position of the drive shaft 62 can be moved as needed. After moving the drive shaft 62, only the length of the connecting ropes 50 needs to be adjusted without affecting the rising and falling of the cleaning frame 30, thus improving its applicability.

[0065] In one embodiment, a counterweight is attached to the cleaning frame 30. Because the cleaning frame 30 is relatively light, when the motor 61 drives the first winding reel 64 and the second winding reel 65 to release the connecting rope 50, the cleaning frame 30 sinks slowly. This may cause the connecting rope 50 to detach from the fixed pulley 63, or the cleaning frame 30 may tilt during sinking, causing it to get stuck on the disinfection box 20 and unable to sink smoothly. By adding a counterweight, the cleaning frame 30 can sink smoothly, keeping the connecting rope 50 taut and preventing it from detaching from the fixed pulley 63.

[0066] In one embodiment, an inclined guide plate 70 is connected to the cleaning frame 30. The guide plate 70 is arranged along the direction of sewage flow, with one end of the guide plate 70 facing the direction of sewage flow being lower and the other end being higher. One or more guide plates 70 may be provided.

[0067] In this embodiment, the connecting rope 50 is released, at which time the cleaning frame 30 can sink. When the water flows through the position of the cleaning frame 30, the sewage flows through the guide plate 70, thereby generating downward pressure on the guide plate 70, which causes the cleaning frame 30 to move down, so that the connecting rope 50 can always be kept taut.

[0068] In one embodiment, the cleaning frame 30 includes a first connecting plate 31, a second connecting plate 32, a first connecting rod 33, and a second connecting rod 34.

[0069] The two ends of the first connecting plate 31 are fixedly connected to two connecting ropes 50, respectively. The two ends of the second connecting plate 32 are fixedly connected to two connecting ropes 50, respectively. The second connecting plate 32 is parallel to the first connecting plate 31, and the first connecting plate 31 and the second connecting plate 32 are located on both sides of the multiple disinfection boxes 20. Multiple first connecting rods 33 are provided, and the two ends of the first connecting rods 33 are connected to the first connecting plate 31 and the second connecting plate 32, respectively. Each first connecting rod 33 is located between two adjacent disinfection boxes 20. Two second connecting rods 34 are provided, and the two ends of the second connecting rods 34 are connected to the first connecting plate 31 and the second connecting plate 32, respectively. Multiple first connecting rods 33 are located between two second connecting rods 34. Each first connecting rod 33 has a row of bristles 40 distributed along its axial direction on both sides; the second connecting rod 34 has a row of bristles 40 distributed along its axial direction on the side facing the disinfection box 20. The guide plate 70 is fixedly connected to the second connecting rod 34.

[0070] In this embodiment, the four connecting ropes 50 respectively drive the first connecting plate 31 and the second connecting plate 32 to rise and fall, thereby driving the first connecting rod 33 and the second connecting rod 34 to rise and fall, so that the brush bristles 40 brush away the impurities on the outer wall of the disinfection box 20.

[0071] In one embodiment, the disinfection box 20 includes a limiting plate 22, a light-transmitting cover 23, and a lamp support plate 24.

[0072] A handle is provided on the limiting plate 22, which can abut against the mounting plate 10. The light-transmitting cover 23 is rectangular, with its upper end open and connected to the limiting plate 22. The lower end of the light-transmitting cover 23 is adapted to and can pass through the strip mounting hole 11. The light-transmitting cover 23 can be made of glass. Specifically, the light-transmitting cover 23 can be snap-fitted to the limiting plate 22 or bolted to it. Two lamp tube support plates 24 are arranged parallel to each other, vertically. The upper end of the lamp tube support plates 24 is connected to the limiting plate 22, and the lower end of the lamp tube support plates 24 is inserted into the light-transmitting cover 23. Both ends of the ultraviolet lamp tube 21 are connected to the two lamp tube support plates 24 respectively.

[0073] In this embodiment, multiple ultraviolet lamps 21 are mounted on two lamp support plates 24, and then the limiting plate 22 is connected to the upper end of the light-transmitting cover 23. The light-transmitting cover 23 is then inserted into the strip-shaped mounting hole 11, and the installation is complete when the limiting plate 22 abuts against the mounting plate 10. For maintenance, simply pull the handle on the limiting plate 22 to remove the entire light-transmitting cover 23, which is quite convenient.

[0074] In one embodiment, the second connecting rod 34 has a vertically oriented guide groove 35 on the side facing away from the disinfection box 20; a guide rod 13 is connected to the lower end of the mounting plate 10 at the position corresponding to the guide groove 35; the guide rod 13 and the guide groove 35 slide in a vertical manner.

[0075] In this embodiment, the cleaning frame 30 can be vertically raised and lowered relative to the mounting plate 10 due to the sliding cooperation between the guide rod 13 and the guide groove 35.
