Abstract

A tangential inflow deep cone concentrator system. The water inlet pipe enters tangentially from the side plate of the water inlet of the first-stage deep cone concentrator. Under the action of inertia, it descends spirally along the wall of the water inlet pipe of the first-stage deep cone concentrator. At the same time, the flocculant added from the water inlet of the first-stage deep cone thickener fully reacts with the sand and gravel aggregate wastewater, large particles settle down, and the supernatant containing a small amount of particles flows from the overflow tank of the first-stage deep cone thickener along the tangential direction Enter the water inlet of the second-stage deep cone thickener, do a spiral downward movement, the particles are precipitated under the action of the flocculant, and the clean water enters the clean water collection pipe from the overflow tank of the second-stage deep cone thickener. It saves the central water inlet of the traditional deep cone thickener and the agitator installed on the top of the sludge buffer tank. It has a simple structure, no power consumption, convenient maintenance, and saves investment and operating costs.
