Description

Technical Field

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

[0002] Wastewater refers to water bodies containing various pollutants, usually originating from household, industrial, and agricultural activities. It is wastewater discharged from cities and villages and contains a large number of harmful substances, such as organic matter, chemical substances, and pathogenic microorganisms. Ultraviolet disinfection devices are needed when treating wastewater. Wastewater ultraviolet disinfection devices are equipment that kill pathogenic microorganisms in wastewater through ultraviolet radiation. They use ultraviolet light to irradiate bacteria, viruses, algae, and other microorganisms in the water, destroying their DNA or RNA and rendering them unable to reproduce and cause disease, thereby achieving the purpose of disinfection and sterilization.

[0003] Existing ultraviolet disinfection devices for wastewater typically use ultraviolet lamps to sterilize and disinfect wastewater. However, ultraviolet lamps are usually fixed in place and cannot be moved back and forth. The path of water flowing through the lamp tube is fixed. Fixed ultraviolet lamps may result in insufficient ultraviolet irradiation in some areas of the water. This is especially noticeable when the wastewater flow rate is large or the flow is strong. Some parts of the water may not be fully irradiated, resulting in incomplete disinfection.

[0004] Therefore, we have made improvements to this by proposing an ultraviolet disinfection device for wastewater discharge. Utility Model Content

[0005] The purpose of this invention is to address the issue that existing wastewater ultraviolet disinfection devices typically use ultraviolet lamps to sterilize and disinfect wastewater. However, these lamps are usually fixed in place and cannot be moved back and forth. The path of the water flowing through the lamp tube is also fixed. This fixed ultraviolet lamp may result in insufficient ultraviolet irradiation in certain areas of the water. This is especially noticeable when the wastewater flow rate is high or the flow is strong, as some parts of the water may not be adequately irradiated, leading to incomplete disinfection.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] Wastewater discharge is disinfected using ultraviolet light to improve the above-mentioned problems.

[0010] The disinfection components are designed to quickly sterilize and disinfect wastewater. During the sterilization process, the ultraviolet lamps can be moved back and forth, ensuring that different areas of the wastewater receive uniform ultraviolet irradiation. Fixed ultraviolet lamps may result in insufficient ultraviolet irradiation in some areas, especially when the wastewater flow rate is fast or the water body is complex. The back-and-forth movement design allows the ultraviolet rays to act evenly on the entire water flow, thereby improving the overall disinfection effect.

The side of the bidirectional lead screw near the protective shell is movably connected to the protective shell. Fixed blocks are threaded to the top and bottom of the surface of the bidirectional lead screw. A placement plate is fixedly installed on one side of the fixed block, and an ultraviolet lamp is provided on one side of the placement plate.

[0014] In a preferred embodiment of the ultraviolet disinfection device for wastewater discharge provided by this utility model, a limiting plate is sleeved on the surface of the motor, and the side of the limiting plate near the protective shell is fixedly connected to the protective shell.

[0015] In a preferred embodiment of the ultraviolet disinfection device for wastewater discharge provided by this utility model, sliding blocks are fixedly installed on both the front and rear sides of one side of the placement plate, and a sliding rod is slidably connected to the inner cavity of the sliding block. The top and bottom of the sliding rod are fixedly installed in the inner cavity of the outer shell.

[0016] In a preferred embodiment of the ultraviolet disinfection device for wastewater discharge provided by this utility model, two positioning plates are fixedly installed on the front and rear sides of the conveying shell, and the side of the positioning plate closest to the shell is fixedly connected to the shell.

[0017] In a preferred embodiment of the ultraviolet disinfection device for wastewater discharge provided by this utility model, two stabilizing plates are fixedly installed on the front and rear sides of the protective shell, and the side of the stabilizing plate closest to the shell is fixedly connected to the shell.

[0035] Example 1

[0036] Please refer to Figure 1-5 An ultraviolet disinfection device for wastewater discharge includes a housing 1. A conveying housing 2 is fixedly installed on the left side of the housing 1. A feeding housing 3 is fixedly installed at the bottom left side of the conveying housing 2. A discharging housing 4 is fixedly installed at the top right side of the conveying housing 2. A protective housing 5 is fixedly installed at the top of the housing 1. A disinfection component 6 is fixedly installed at the top of the protective housing 5. Support legs 7 are fixedly installed at the four corners of the bottom of the housing 1. A sewage pipe 8 is connected to the bottom of the housing 1. A solenoid valve 9 is installed on the surface of the sewage pipe 8. The disinfection component 6 includes a motor 601, which is fixedly installed on the top of the protective housing 5. A rotating rod 602 is fixedly installed at the output end of the motor 601. Three connecting sleeves 603 are fixedly installed on the surface of the rotating rod 602. A stirring plate 604 is fixedly installed on the surface of the connecting sleeves 603. Two first synchronous pulleys 605 are fixedly installed on the top of the surface of the rotating rod 602. A second synchronous pulley 607 is provided on the opposite side of each of the two first synchronous pulleys 605. A first belt 606 is connected between the surfaces of the first synchronous pulleys 605 and the second synchronous pulleys 607. A double-acting lead screw 608 is fixedly installed in the inner cavity of the second synchronous pulley 607. The side of the double-acting lead screw 608 closest to the protective shell 5 is movably connected to the protective shell 5. Fixed blocks 609 are threadedly connected to the top and bottom of the surface of the double-acting lead screw 608. A placement plate 610 is fixedly installed on one side of the fixed block 609, and an ultraviolet lamp 611 is provided on one side of the placement plate 610. A limiting plate 617 is sleeved on the surface of the motor 601, and the side of the limiting plate 617 closest to the protective shell 5 is fixedly connected to the protective shell 5. Sliding blocks 618 are fixedly installed on the front and rear sides of one side of the placement plate 610. A sliding rod 619 is slidably connected to the inner cavity of the sliding block 618, and the top and bottom of the sliding rod 619 are fixedly installed in the inner cavity of the outer shell 1. Two positioning plates 10 are fixedly installed on the front and rear sides of the conveying shell 2, and the side of the positioning plate 10 closest to the outer shell 1 is fixedly connected to the outer shell 1. Two stabilizing plates 11 are fixedly installed on the front and rear sides of the protective shell 5, and the side of the stabilizing plate 11 closest to the outer shell 1 is fixedly connected to the outer shell 1.

[0037] During implementation, when wastewater needs to be sterilized and disinfected, motor 601 is started. Motor 601 drives rotating rod 602, which in turn drives connecting sleeve 603, which in turn drives stirring plate 604. The rotation of multiple stirring plates 604 agitates the wastewater. Wastewater typically contains suspended solids, silt, and organic matter, which may absorb or scatter ultraviolet light, weakening its killing effect on microorganisms. Agitating the wastewater reduces the deposition and accumulation of these suspended solids, ensuring that ultraviolet light penetrates the water more evenly and effectively irradiates pathogenic microorganisms in the wastewater. The rotation of rotating rod 602 drives two first synchronous pulleys 605 to rotate. The first belt 606 drives the second synchronous pulley 607 to rotate, which in turn drives the bidirectional lead screw 608 to rotate. The bidirectional lead screw 608 then drives two fixed blocks 609 to move in opposite directions. The movement of the fixed blocks 609 causes the placement plate 610 to move, which in turn causes the ultraviolet lamps 611 to move. This allows the two ultraviolet lamps 611 to move back and forth. The reciprocating movement of the ultraviolet lamps 611 ensures that different areas in the wastewater receive uniform ultraviolet irradiation. Fixed ultraviolet lamps 611 may result in insufficient ultraviolet irradiation in some areas, especially when the wastewater flow rate is fast or the water body is complex. The reciprocating movement design allows the ultraviolet rays to act evenly on the entire water flow, thereby improving the overall disinfection effect.

[0038] Example 2

[0039] A third synchronous pulley 612 is fixedly installed on the bottom of the surface of one of the bidirectional lead screws 608. A fourth synchronous pulley 614 is provided on one side of the third synchronous pulley 612. A second belt 613 is connected between the surfaces of the third synchronous pulley 612 and the fourth synchronous pulley 614. A conveying rod 615 is fixedly installed in the inner cavity of the fourth synchronous pulley 614. A spiral conveying blade 616 is fixedly installed on the surface of the conveying rod 615. The side of the conveying rod 615 near the conveying housing 2 is movably connected to the conveying housing 2.

[0040] During implementation, wastewater enters the interior of the conveying shell 2 through the feed shell 3. The rotation of one of the bidirectional lead screws 608 also drives the third synchronous pulley 612 to rotate. The rotation of the third synchronous pulley 612 drives the fourth synchronous pulley 614 to rotate through the second belt 613. The rotation of the fourth synchronous pulley 614 drives the conveying rod 615 to rotate. The rotation of the conveying rod 615 drives the spiral conveying blade 616 to rotate. Through the rotation of the conveying rod 615 and the spiral conveying blade 616 inside the conveying shell 2, the wastewater entering the conveying shell 2 can be evenly conveyed towards the discharge shell 4. Even feeding can avoid the accumulation of solid matter in the wastewater inside the equipment, reduce the risk of equipment blockage, and thus extend the normal operation time of the equipment. Finally, the wastewater enters the interior of the outer shell 1 through the discharge shell 4 for sterilization and disinfection.

[0041] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
