Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment, specifically a spray alkaline washing wastewater treatment device. Background Technology

[0002] Wastewater treatment uses physical, chemical, and biological methods to purify wastewater, reduce pollution, and even achieve wastewater recycling and reuse, making full use of water resources. Most wastewater is acidic, so in chemical treatment, alkaline solutions are usually added to neutralize the acidity and alkali of the wastewater.

[0003] Existing spray-type alkaline washing wastewater treatment devices typically use fixed spray heads, resulting in a limited spray area. This means that some areas may not receive the alkaline solution, affecting the wastewater treatment effect. Furthermore, the acid-base neutralization reaction generates fixed precipitates that adhere to the bottom and inner walls of the treatment device, making them difficult to remove. Traditional devices use scrapers inside the device for scraping, but the scraped-off precipitates are often large and remain inside, hindering removal. Therefore, we propose a spray-type alkaline washing wastewater treatment device to address these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a spray alkaline washing wastewater treatment device to solve the problems mentioned in the background art. In the existing spray alkaline washing wastewater treatment devices, the spray heads are mostly fixed, resulting in a fixed spray range. Some areas may not be sprayed with alkaline solution, affecting the wastewater treatment effect. Furthermore, the acid-base neutralization reaction will generate fixed precipitates, which will adhere to the bottom and inner wall of the treatment device and are difficult to remove. Traditional devices add scrapers inside the device for scraping, but the scraped precipitates are large and still remain inside the treatment device, making them difficult to remove.

[0021] Please see Figures 1-5This utility model provides a technical solution: a spray alkaline washing wastewater treatment device, including a treatment tank 1, a drive motor 2, a water pump 6, and a servo motor 23. The drive motor 2 is installed on the lower side of the treatment tank 1, and a rotating shaft 3 is fixed to the output end of the drive motor 2. Agitator blades 4 are uniformly fixed to the surface of the rotating shaft 3. An alkaline supply tank 5 is fixed above the treatment tank 1. A water pump 6 is installed on one side of the upper part of the treatment tank 1, and one end of the water pump 6 is connected to the alkaline supply tank 5 via a water suction pipe 7. The other end of the water pump 6 is connected to a drain pipe 8, and a connecting sleeve 9 is connected below the drain pipe 8. A liquid supply pipe 10 penetrating the surface of the treatment tank 1 is connected to the connecting sleeve 9, and spray heads 11 are uniformly installed below the liquid supply pipe 10. The end of the liquid supply pipe 10 is connected to the inside of the connecting sleeve 9 via a sealing ring. The liquid supply pipe 10 and the connecting sleeve 9 are connected by a rotatable connection. Two sets of spray heads 11 are provided below the liquid supply pipe 10 to facilitate the rotation of the liquid supply pipe 10 inside the connecting sleeve 9 so that the device can swing and spray. A gear 12 located outside the treatment box 1 is fixed on the surface of the liquid supply pipe 10. A turntable 13 is fixed on the surface of the rotating shaft 3 located outside the treatment box 1. A connecting rod 14 is rotatably connected above the turntable 13. A slide rail 17 is rotatably connected above the connecting rod 14. Tooth blocks 18 are evenly fixed on one side of the surface of the slide rail 17. The slide rail 17 and the slider 16 on the surface of the side plate 15 form a snap-fit ​​sliding connection. The tooth blocks 18 on the surface of the slide rail 17 are meshed with the gear 12 to facilitate the meshing and rotation of the tooth blocks 18 on the surface of the slide rail 17 and the gear 12, which facilitates the rotation of the liquid supply pipe 10.

[0022] Please see Figures 1-5 A side plate 15 is fixed to the side of the treatment box 1, and a slider 16 is fixed to the surface of the side plate 15. A scraper 19 is installed inside the treatment box 1. Slots 21 are opened at both ends of the upper part of the treatment box 1, and a protective cover 25 is fixed above the slots 21 on the upper part of the treatment box 1. A servo motor 23 is fixed to the side of the protective cover 25, and a servo motor 23 is fixed to the end of the servo motor 23. A rotating lead screw 22 is fixed to the surface of the servo motor 23, and a positioning slide rod 24 is fixed to the upper part of the treatment box 1 away from the rotating lead screw 22. A water inlet pipe 26 is installed on the upper side of the treatment box 1. A water outlet pipe 27 is provided on the lower front side of the treatment box 1. The scraper 19 is arranged in a "U" shape, and the end of the scraper 19 is fitted to the inner surface of the treatment box 1. The two ends of the scraper 19 are evenly fixed with tamping rods 20, so that the tamping rods 20 on both sides of the scraper 19 can crush the fixed sediment. The rotating screw 22 is threadedly connected to the upper side of the scraper 19, and the upper other side of the scraper 19 is slidably connected to the positioning slide rod 24, so that the rotating screw 22 and the scraper 19 can move threadedly, so that the scraper 19 can slide on the positioning slide rod 24, which facilitates the movement and scraping of the scraper 19.

[0023] Working principle: First, when in use, the drive motor 2 is turned on, which drives the agitator 4 to rotate through the rotating shaft 3. At the same time, the rotating shaft 3 drives the turntable 13 to rotate, which in turn drives the connecting rod 14 to make a circular motion. This causes the connecting rod 14 to drive the slide rail 17 to slide up and down on the slider 16. When sliding, the toothed blocks 18 on the surface of the slide rail 17 drive the gear 12 to mesh. This causes the gear 12 to drive the liquid supply pipe 10 to swing back and forth inside the treatment tank 1, so that the spray head 11 swings back and forth to spray, thereby improving the spraying effect of the device.

[0024] During waste removal, the servo motor 23 can be turned on to drive the scraper 19 to move threadedly by rotating the lead screw 22. This allows the scraper 19 to slide on the positioning slide bar 24, so that the scraper 19 can scrape away the sediment on the inner wall and bottom of the treatment tank 1. In conjunction with the use of the tamping rod 20 at the bottom of the scraper 19, the fixed sediment pushed to the end of the treatment tank 1 can be crushed, making it easier to discharge the fixed sediment. This is the working principle of the spray alkaline washing wastewater treatment device.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
