AI Technical Summary
In existing technologies, scale and impurities tend to remain at the bottom of crossflow cooling towers, which can easily pollute water sources when discharged directly, resulting in poor sewage discharge.
A water collection base, scraper, chemical dosing mechanism, and mixing mechanism are designed. The scraper removes water scale and collects it in the water collection base. The scraper mixing device is equipped with a dual-axis motor 4, which drives a guide screw 5 to rotate. This causes the scraper to move towards each other, scraping off the scale and collecting it in the middle of the water collection base. Combined with the chemical dosing and mixing mechanisms, the chemical is fully mixed with the water to soften the water.
It effectively removes scale, enhances the cleaning effect at the bottom of the crossflow cooling tower, prevents pollution, and improves the sewage discharge effect.
