Two-stage concentration and sedimentation high-concentration mineral processing wastewater treatment equipment

Abstract

The invention belongs to the technical field of high-concentration mineral processing wastewater treatment, and particularly relates to two-stage concentration and sedimentation high-concentration mineral processing wastewater treatment equipment. The two-stage concentration and sedimentation high-concentration mineral processing wastewater treatment equipment comprises a flocculation cylinder anda sedimentation pool; and a rotating shaft is arranged at the axis of the flocculation cylinder, a stirring rod or stirring paddle blades are arranged at the rotating shaft, an ore pulp feeding pipeand a flocculant feeding pipe are arranged at a top end opening of the flocculation cylinder, and a discharging outlet is constituted by a bottom end opening of the flocculation cylinder. The two-stage concentration and sedimentation high-concentration mineral processing wastewater treatment equipment further comprises a threaded rake frame, the threaded rake frame can rotate around the axis of the sedimentation pool, and a scroll-shaped scraping plate is arranged on the face, facing the bottom end face of the sedimentation pool, of the threaded rake frame; a coagulation cylinder is further coaxially arranged on the outer wall of the flocculation cylinder in a sleeving mode; the two-stage concentration and sedimentation high-concentration mineral processing wastewater treatment equipment further comprises a coagulant feeding pipe used for pumping a coagulant into a cylinder cavity of the coagulation cylinder; and the agent adding refinement degree is high, the flocculation effect is better, and the purpose of high-efficiency treatment of high-concentration mineral processing wastewater is achieved synchronously.

Description

technical field [0001] The invention belongs to the technical field of high-concentration mineral processing wastewater treatment, and in particular relates to a treatment device for two-stage concentration and sedimentation of high-concentration mineral processing wastewater. Background technique [0002] Mineral resources are the basic material for the survival and development of a country, and the deep processing and utilization of minerals is an important means of building a green and modern society. There are two main problems in my country's mineral mining: one is that with the deepening of mechanized mining, a large number of gangues are mixed into the raw ore; decline; the above situation makes the existing ores need to be processed before they can be fully utilized. At present, most of the mineral processing plants in our country adopt the wet mineral processing process, which leads to a large amount of high-concentration mineral processing wastewater in the process...

Problems solved by technology

There are two main problems in my country's mineral mining: one is that with the deepening of mechanized mining, a large number of gangues are mixed into the raw ore; decline; the above situation makes the existing ore need to be processed before it can be fully utilized

At the same time, in the process of ore sorting, a large number of heavy metal ions and fine suspended particles will enter the mineral processing wastewater, making the composition and properties of the wastewater complex, with many toxic and harmful substances

If the above mineral processing wastewater is discharged directly without treatment, it will not only cause waste of water resources, but also cause serious environmental pollution accidents; and if it is directly reused without treatment, it will interfere with the overall stability of the separation process and affect Flotation Concentrate Quality and Beneficiation Index

At present, most of the processing methods for mineral processing wastewater are treated by special concentrators, which occupy a large area and have low efficiency, and the dosing process is mostly extensive and centralized, especially in the treatment of high-concentration mineral processing wastewater. less effective
