Description

Technical Field

[0001] The utility model relates to the technical field of slag discharge equipment, in particular to a controllable slag discharge air flotation device. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. In sewage treatment projects, flotation devices are often used. The flotation device is a scraper installed on the top, which can scrape the suspended sludge in the floating wastewater to achieve the purpose of sewage purification. The device can effectively reduce the content of suspended solids and COD in sewage. Because of its high efficiency, it has been widely used in the field of sewage treatment. At present, some debris sludge will settle at the bottom of the flotation device on the market. These debris accumulates over time and is difficult to remove, thus occupying the volume of the flotation device and reducing the effective volume of the flotation device. In addition, due to the disturbance of the water body, it is easy for the accumulated debris at the bottom to re-integrate into the water and flow into the next process along the water flow, which brings difficulties to the later process. And this debris is easy to enter the air flotation dissolved pump system, block the pump body, increase the failure rate, and increase the maintenance cost. At present, the solution to this problem is generally to add a venting pipe, open the valve, and let the bottom water flow drive the debris to be removed. However, this method can only remove some debris that is close to the venting port or light in weight. In the end, the flotation can only be completely emptied for cleaning at intervals, which is time-consuming and labor-intensive, and may cause the factory to stop production and affect economic benefits. To this end, we propose a controllable slag flotation device. Utility Model Content
