Description

Technical Field

[0001] The utility model belongs to the technical field of road rainwater disinfection, and particularly relates to a road rainwater purification and disinfection device. Background Technique

[0002] Road rainwater disinfection and purification is an important environmental protection measure, which can effectively reduce the pollutants carried by rainwater runoff during the process of flowing downward, prevent these pollutants from entering natural water bodies and causing pollution; according to the search results, the technological process of road rainwater disinfection and purification usually includes the following steps: rainwater collection: collecting the rainwater in areas such as roads through facilities such as rainwater collection pipes and drainage ditches; initial runoff and pollution interception: the initial rainwater may contain more pollutants, so runoff treatment is required to remove these pollutants; rainwater storage: the preliminarily treated rainwater is stored in a rainwater storage module or a reservoir; filtration and purification: when the stored rainwater needs to be used, it will undergo further filtration and purification treatment to remove suspended solids and particulate matters in the water; disinfection: the purified rainwater also needs to be disinfected to ensure water quality safety; common disinfection methods include ultraviolet disinfection or the use of disinfectants.

[0003] Currently, since road rainwater contains leaves, sediment, etc., it is necessary to filter the rainwater before disinfection and purification, and since there will be some suspended solids in the rainwater, it is necessary to add a flocculant to the rainwater during disinfection and purification to make the suspended solids flocculate and float. However, since the rainwater is continuously added during rainwater purification and disinfection, the addition of the flocculant needs to be added along with the continuous addition of the rainwater. Based on this, a road rainwater purification and disinfection device is proposed. Content of the Utility Model

[0020] Embodiment

[0021] As Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, a road rainwater purification and disinfection device includes a box body 1. A water inlet pipe 3 is fixedly connected to the top of the box body 1. A medicine adding pipe 4 is fixedly connected to the top of the box body 1. A chemical adding pipe 5 is fixedly connected to the top of the medicine adding pipe 4. The medicine adding pipe 4 and the water inlet pipe 3 are connected by a connecting shaft 6. A blade 7 is fixedly connected to the part of the connecting shaft 6 located inside the water inlet pipe 3. A medicine adding roller 8 is fixedly connected to the part of the connecting shaft 6 located inside the medicine adding pipe 4. The chemical adding pipe 5 is connected to a medicine box filled with flocculant. A medicine adding hole 9 is provided on the medicine adding roller 8. A box cover 2 is installed on the side wall of the box body 1. A sewage outlet 10 is provided on the side wall of the box body 1. The sewage outlet 10 is communicated with a sewage pipe. The sewage outlet 10 is located at the top of the fixed rod 18. A drain pipe 11 is fixedly connected to the bottom of the box body 1 on one side of the sewage outlet 10. A filter plate is installed at the water inlet end of the drain pipe 11. A valve is installed inside the drain pipe 11. A sewage discharge valve 25 is installed at the bottom of the box body 1. When it is necessary to clean the sediment in the box body 1, opening the sewage discharge valve 25 can clean the sediment in the box body 1.

[0022] During use, rainwater on the road enters the box body 1 through the water inlet pipe 3. During the process of the rainwater passing through the water inlet pipe 3, the rainwater will impact on the blades 7, causing the blades 7 to rotate. Then, the medicine adding roller 8 is driven to rotate through the connecting shaft 6, so that the flocculant entering the medicine adding hole 9 is added into the box body 1 through the medicine adding pipe 4 by the rotation of the medicine adding roller 8 and is mixed with the rainwater in the box body 1. Thus, the suspended substances in the rainwater in the box body 1 are flocculated into large pieces under the action of the flocculant, float to the water surface, and are discharged through the sewage outlet 10. This realizes the quantitative addition of the flocculant along with the addition of the rainwater, ensures the flocculation of the rainwater by the flocculant, saves resources, and prevents the waste of the flocculant.

[0023] As Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a fixed plate 24 is fixedly connected inside the box body 1. A second spring 23 is fixedly connected to the top of the fixed plate 24. A filter screen 21 is fixedly connected to the top of the second spring 23. A magnetic rod 22 is fixedly connected to the horizontal part at the bottom of the filter screen 21. The filter screen 21 fits on the inner wall of the box body 1. The box cover 2 is located above the filter screen 21. A motor 12 is installed on the top of the box body 1. The output end of the motor 12 is fixedly connected to a rotating shaft 13. A limiting rod 14 is fixedly connected to the outer wall of the rotating shaft 13. A fixed disk 15 is fixedly connected to the outer wall of the rotating shaft 13 at the bottom of the limiting rod 14. A first spring 16 is fixedly connected to the top of the fixed disk 15. A limiting sleeve 17 is slidably connected to the outer surface of the limiting rod 14. The top of the first spring 16 is fixedly connected to the bottom of the limiting sleeve 17. Fixed rods 18 are fixedly connected to both the top and the bottom of the limiting sleeve 17. Ultraviolet lamps 19 are fixedly connected to the adjacent sides of the two fixed rods 18 at the top and the bottom of the limiting sleeve 17. A magnetic column 20 is fixedly connected to the top of the fixed rod 18 at the top of the limiting sleeve 17. The rotating shaft 13 passes through the box body 1 and is rotatably connected to the box body 1. The rotating shaft 13 passes through the middle of the filter screen 21. The magnetic column 20 is adapted to the magnetic rod 22. The first spring 16 is sleeved on the limiting rod 14.

[0024] During use, the rainwater entering the box body 1 will pass through the filter screen 21 to filter the impurities in the rainwater. Since the filter screen 21 is inclined, the impurities will move towards the edge of the box body 1. When the rainwater enters, the motor 12 and the ultraviolet lamp 19 are started, so that the rotating shaft 13 drives the fixed rod 18 to rotate through the limiting rod 14 and the limiting sleeve 17, making the ultraviolet lamp 19 rotate. The rainwater filtered by the filter screen 21 is mixed with the rainwater and the flocculant by the rotation of the ultraviolet lamp 19, so that the suspended substances in the rainwater are flocculated into large suspended substances. At the same time, the ultraviolet lamp 19 will also disinfect the rainwater during the mixing process. During this process, the rotation of the fixed rod 18 will also drive the magnetic column 20 to rotate. When the magnetic column 20 reaches the position where the magnetic rod 22 is located, the filter screen 21 and the fixed rod 18 will move one up and one down. When the magnetic column 20 leaves the position where the magnetic rod 22 is located, the filter screen 21 will vibrate under the action of the second spring 23 to prevent the filter screen 21 from being blocked, resulting in the rainwater being unable to enter the position where the ultraviolet lamp 19 is located, affecting the disinfection and purification of the rainwater. The fixed rod 18 vibrates under the action of the first spring 16, making the ultraviolet lamp 19 vibrate, shaking off the impurities adhered to the outer surface of the ultraviolet lamp 19, preventing the attachment of impurities from causing the ultraviolet rays to be unable to be emitted into the rainwater, affecting the quality and efficiency of the ultraviolet lamp 19 in disinfecting and purifying the rainwater;

[0025] During the disinfection and purification process, when the suspended substances can be discharged through the sewage outlet 10, the valve in the drain pipe 11 is opened, so that the drain pipe 11 discharges the purified and disinfected water in the box body 1, and the sewage outlet 10 can always discharge the suspended substances during the discharge.

[0026] The above embodiments only represent several implementation modes of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
