Product Introduction
The thickener (also known as a concentrator) has the functions of concentration and clarification, and it achieves solid-liquid separation based on the principle of gravity sedimentation. It is divided into two types: center-driven and peripheral-driven.
The center-driven thickener mainly consists of a circular pool, rakes, and a drive mechanism. The bottom of the pool is a gently sloping conical shape, with an inclination angle of 6° to 12° relative to the horizontal plane. The pool is generally made of concrete, and smaller diameters can also be made of welded steel plates. There is an annular overflow tank at the upper edge of the inner wall of the pool for discharging overflow. The vertical shaft located in the center of the pool is connected to the rake mechanism. The rake mechanism consists of rake arms, rake teeth, and reinforcing tie rods. Two radially arranged rake arms are perpendicular to each other in a cross shape. To ensure that all the concentrated product settled at the bottom of the pool is discharged through the discharge port, the rake teeth are installed on the rake arms at an angle of about 30°.
Product Features
(1) An additional degassing tank is added to avoid solid particles adhering to bubbles, resembling a "parachute" sedimentation phenomenon.
(2) The feed pipe is located below the liquid surface to prevent gas from being brought in during feeding.
(3) The feed sleeve is lowered and equipped with a receiving plate, allowing the incoming slurry to fall evenly and smoothly, effectively preventing the phenomenon of turbulence caused by residual pressure during feeding;
(4) An internal overflow weir is added to ensure that materials flow according to the specified travel, preventing the "short-circuit" phenomenon;
(5) The overflow weir is changed to a serrated shape, improving the suction phenomenon caused by uneven drainage due to the overflow weir not being level;
(6) The rake teeth are changed from a linear diagonal shape to a curved shape, allowing the slurry to not only move towards the center rake but also providing a force that "presses" towards the center, resulting in a higher concentration of the bottom flow of the discharged ore, thereby increasing the processing capacity.
