Description

Technical Field

[0001] The utility model relates to the technical field of thickeners, and more specifically to a thickener with multi-layer washing. Background Art

[0002] Thickener is a solid-liquid separation equipment based on gravity sedimentation. It is usually built into a cylindrical shallow tank with a conical bottom made of concrete, wood or metal welded plates as structural materials. It can concentrate the slurry with a solid weight of 10% to 20% into an underflow slurry with a solid content of 45% to 55% through gravity sedimentation, and with the help of the slow-running rake installed in the thickener, the thickened underflow slurry is discharged from the underflow port at the bottom of the thickener. The upper part of the thickener produces a relatively clean clarified liquid (overflow) which is discharged from the annular chute at the top.

[0003] After searching, it was found that a Chinese patent with announcement number CN219355344U disclosed a thickener with multi-layer washing function. In this document, the motor drives the scraping rod to rotate, gradually scraping the material onto the conical filter. Although the top of the filter is flushed through the water inlet pipe, the flushing range is small and the problem of filter blockage cannot be solved. For this reason, we propose a thickener with multi-layer washing. Utility Model Content
