Thickening Tank is widely used in cyanide plants for leaching and washing. They have a concentrated washing and buffering effect. According to the different transmission modes, the thickener can be divided into two types: central transmission type and peripheral transmission type. The specification of the thickener, the central transmission type is generally expressed by the inner diameter of the thickener tank, and the peripheral transmission type is represented by the diameter of the circular rail.
The central transmission type thickening tank is mainly composed of a circular ring, a tweezers and a transmission mechanism. The pool is generally made of concrete structure, and the diameter is small. It can also be welded by steel plates. The upper edge of the inner wall of the pool has a ring that discharges overflow. The vertical axis in the center of the pool is connected to the rafter mechanism.
The forceps mechanism consists of the arm, the caries and the reinforcement bar. The two radially arranged jaw arms are perpendicular to each other in a cross shape. In order to be able to discharge the concentrated product deposited on the entire bottom of the pool from the discharge opening, the molar is mounted on the arm at an inclination angle of about 30°with the arm, and the vertical shaft is installed in the inner hole of the worm wheel of the worm gear. In the middle, the two are in a sliding fit, and because of the positioning function of the connecting key, it can only move downward in the axial direction in the worm wheel.
The thickening tank is a solid-liquid separation device based on gravity sedimentation. It is usually a cylindrical shallow groove with a conical bottom made of concrete, wood or metal welded plate as a structural material. The slurry containing solid weight of 10% to 20% can be concentrated by gravity sedimentation into an underflow slurry with a solid content of 45% to 55%, and is installed in a thick machine for slow running (1/3 to 1/5 r/min). The action of the crucible causes the thickened underflow slurry to be discharged from the bottom flow port at the bottom of the thickener.
