Description

Technical Field

[0001] The utility model relates to the technical field of stirring equipment, in particular to an energy-saving and environment-friendly stirring machine for industrial wastewater treatment. Background Art

[0002] In the process of industrial wastewater treatment, the main function of the mixer is to mix and disperse the solid, liquid and other pollutants in the wastewater to make them evenly distributed, which is conducive to the subsequent treatment process;

[0003] In the process of industrial wastewater treatment, chemicals are added to cooperate with the mixer to further treat the wastewater. The chemicals can react chemically with harmful substances in the wastewater to form precipitation, bubbles or other substances that are easy to separate, thereby removing pollutants in the wastewater. The stirring action of the mixer can increase the solubility of oxygen and mix chemicals such as flocculants with the wastewater. For example, the Chinese utility model patent disclosed in the publication number CN219024150U discloses a desulfurization wastewater flocculation mixer that is easy to clean. The application is provided with a cleaning cylinder, which is used by the first stirring rod and the second stirring rod in the cleaning process. The sliding on the sliding hole in the cleaning cylinder allows the cleaning cylinder to scrape and clean the outer wall of the stirring rod to replace the use of other tools. Although the restrictions on the cleaning of the stirring rod are reduced and the convenience of cleaning the stirring rod is increased, when flocculants and other chemicals are mixed with sewage, flocculants and other chemicals are added from the top of the stirring container. Therefore, it takes a long time for the chemicals to be evenly dispersed into the sewage under the action of gravity. Even if the sewage is stirred by this application, it will be difficult to disperse the chemicals quickly due to the poor position of adding the chemicals, thereby reducing the mixing reaction efficiency of the sewage and the chemicals.
