Titanium dioxide sedimentation device

Abstract

The titanium dioxide settling device of the invention belongs to the field of titanium preparation. The purpose is to improve the recycling rate of titanium dioxide. It includes a bracket, a tank body and a drainage tube; the tank wall and the tank bottom of the tank body surround a settling tank with an open upper end; the tank body is supported on the bracket, and the drain tube is supported on the bracket and located in the settlement tank; the connection between the tank body and the drain tube A flocculation zone is formed between the cylinder walls; a sedimentation zone below the flocculation zone is formed between the bottom of the drainage cylinder and the bottom of the tank; a ring overflow groove is arranged on the inner wall of the tank body; A plurality of drainage holes are connected to the cavity of the drainage cylinder; a filter cloth covering the drainage cylinder is set on the cylinder wall of the drainage cylinder; and a drain pipe communicating with the cavity of the drainage cylinder is provided. The invention avoids the interference of drainage to the sedimentation area, prevents the titanium dioxide from being taken away by pumping water, and improves the recycling rate of the titanium dioxide. Moreover, the overflow tank allows the titanium dioxide wastewater to enter the tank body in an overflow manner, reducing the disturbance of water inflow.

Description

technical field [0001] The invention belongs to the field of titanium preparation, in particular to electrolytic equipment for preparing high-purity titanium. Background technique [0002] After the titanium dioxide base material is filtered, washed, squeezed and dried by a filter press, some titanium dioxide will remain in the washing water, resulting in waste of titanium dioxide. In order to improve the utilization rate and economic benefits of titanium dioxide, titanium dioxide wastewater is often used The sedimentation device recovers titanium dioxide. At present, titanium dioxide wastewater settling devices usually use a settling chamber to deposit titanium dioxide at the bottom of the settling chamber, and use a pumping pipe to pump out the upper water to separate the titanium dioxide precipitate from water. However, in this device, the starting time of pumping water in the pumping pipeline must be after the titanium dioxide precipitation and water separation, and in ...
