Multifunctional on-line monitoring pretreatment device for tailing slurry

Abstract

The invention relates to a multifunctional on-line monitoring pretreatment device for tailing slurry. The multifunctional on-line monitoring pretreatment device consists of a slurry feeding pump, a slurry feeding valve, a solid-liquid separator, a clean water valve, an internal supporting structure, a water discharging electric control switch valve, a flow meter, a PH detector, a U-shaped liquid storage pipe, a tail liquid recycler, a cyanide electric control switch valve, a cyanide detector, a sewage discharging valve, a slurry discharging pump, a slurry discharging electric control switch valve, a micro clean water pump and a PLC (Programmable Logic Controller) control module which are mounted inside an electrical control cabinet in an integrated manner. By the adoption of a filter principle, on the premise of solid-liquid separation, the multifunctional on-line monitoring pretreatment device realizes that the overflow filter area at the top of the separator is large; by the cooperation with the principle that heavy minerals settle down and clear liquid floats up, solid-liquid separation is facilitated, and the service life of filter cloth can be prolonged; pressurized filtering guarantees the continuous discharging speed of the clear liquid; the U-shaped pipe is combined with a PH continuous detection system and an intermittent cyanide detection system, thus realizing a multifunctional on-line detection function; a PLC automatic control system realizes combination of automatic control of equipment and intensive installation of the control cabinet, so that the equipment is integrated, and installation and management are facilitated.

Description

technical field [0001] The invention relates to an on-line monitoring pretreatment device, in particular to a multifunctional tailings slurry on-line monitoring and pretreatment device, which is suitable for on-line monitoring and pretreatment of multiple elements in the tailings slurry. Background technique [0002] At present, online monitoring technology is mainly used in water quality monitoring of water treatment process, such as pH value, cyanide content, dissolved oxygen and other monitoring. Participation of measurement data in process control can reliably reflect the changing trend of water quality and provide a basis for water treatment process control, so as to achieve the purpose of optimizing water treatment process and improving water treatment efficiency. Online water quality monitoring technology has high reliability and stability. However, the online monitoring sensor cannot achieve the reliability and stability of the monitoring in the slurry system. There...
