A thickener with overflow collection function

Abstract

The utility model discloses a thickener with an overflow collection function. The utility model relates to the technical field of thickener equipment. The thickener with the overflow collection function receives the overflowed stored liquid through an overflow trough and introduces it into a de-impurity box, and intercepts the impurities by using an interception mesh plate to prevent them from entering the overflow collection box. At the same time, the upper end of the interception mesh plate is designed with an inclined structure, which is convenient for concentrating the impurities on the side of the de-impurity box to avoid clogging the pipeline, and is convenient for regular cleaning, which is beneficial to optimizing the de-impurity function of the equipment. The overflow liquid after de-impurity is concentrated by the overflow collection box, and the liquid level of the overflow collection box can be observed and grasped in real time by using a liquid level observation port, which avoids the thickener body overflowing out of the equipment and polluting the equipment and the working environment. At the same time, the overflow liquid can be re-input into the equipment by using a circulation pipe, which is beneficial to the clean production of the thickener equipment and reduces the difficulty of cleaning the equipment.
