Abstract
The utility model relates to the technique of flotation machine for mineral processing, in particular to a simple powerless flotation device. The prior flotation column in the market is expensive, andthe bubble generator is likely to be jammed in the actual production process so as not to suit the reselection of mine tailing products. The simple powerless flotation device comprises a flotation tank body, and a grout feeding pipe arranged in the flotation tank body, wherein the bottom end face of the grout feeding pipe is sealed; a grout outlet is formed on the side wall of the bottom of the grout feeding pipe; an air inlet pipe is connected with the upper part of the grout feeding pipe; a stirring box is arranged on the bottom of the grout feeding pipe; a screen is arranged in the flotation tank body; and a level adjusting device communicated with the flotation tank body is arranged beside the flotation tank body. The simple powerless flotation device obviates the need of flotation column, and is worth of popularization.
Description
Technical field
The utility model relates to mineral dressing flotation technology, particularly a kind of simple unpowered flotation device.
Background technology
According to statistics, mineral resources overall recovery of China and common associated minerals comprehensive utilization of resources rate are respectively about 30% and 35%, a large amount of valuable minerals are promptly arranged along with mine tailing effluxes together.In the valuable mineral, some is can not reclaim owing to technical reason in this section, though some can reclaim under existing technique of preparing condition, does not have owing to production cost is too high to implement.
On the market corresponding low energy consumption or unpowered preparation equipment are arranged also now, flotation column is exactly wherein a kind of, though the traditional relatively agitation impeller flotator of flotation column has simple in structure, energy-efficient advantage, but the choosing again that it costs an arm and a leg, bubble generator easily stops up and is not suitable for product from failing in actual production is chosen and is able to utilization and extention so be difficult in product from failing.
The utility model content
The utility model purpose provides a kind of cheap, simple in structure, simple unpowered flotation device of need not external bubble generator, make it can fully reclaim valuable mineral in the mine tailing, improve the mineral resources comprehensive utilization rate, improve the performance of enterprises, reduce the tailings discharging amount, reduce environmental pollution.
The utility model adopts technical scheme to be: a kind of simple unpowered flotation device, comprise the flotation cell body, in the flotation cell body, be furnished with pulp-inlet pipe, the sealing of pulp-inlet pipe bottom end face, pulp-inlet pipe bottom sidewall has grout outlet, and pulp-inlet pipe top connects air inlet pipe, and the pulp-inlet pipe bottom is furnished with agitator tank, in the flotation cell body, be provided with screen cloth, the other liquid level regulation apparatus that communicates with it that is provided with on the flotation cell side;
The flotation cell body comprises two parts up and down, and top is a cuboid, and the bottom is a cone;
The agitator tank of pulp-inlet pipe bottom is a cavity body of falling the rectangular pyramid;
The air inlet pipe that pulp-inlet pipe top connects is provided with gate valve;
Liquid level regulation apparatus comprises an adjusting gate valve that moves up and down;
Be provided with three layers of screen cloth of upper, middle and lower in the flotation cell body, mesh size is 20mm;
The pulp-inlet pipe bottom is a turbination, and the sidewall grout outlet is a strip.
The utility model is compared with flotation column, does not need to add in addition bubble generator, only relies on flowing of ore pulp, utilizes jet current principle to obtain the needed bubble of flotation, thereby does not have the bubble generator clogging, and is easy and simple to handle; Simple in structure, cost is low; Through to leaded 0.11%, contain zinc 0.64% mine tailing float test, can obtain to contain zinc 14.20%, the rate of recovery of corresponding zinc (mine tailing relatively) is 33.47% zinc concentrate, remarkable in economical benefits; Fully reclaim the valuable mineral in the mine tailing, improve the mineral resources comprehensive utilization rate, improve the performance of enterprises, reduce the tailings discharging amount, reduce environmental pollution.

The specific embodiment
The utility model flotation cell body top is a cuboid, and the bottom is a cone.Be positioned at the pulp-inlet pipe bottom end face sealing of flotation cell central authorities, the pulp-inlet pipe bottom is a turbination, and the sidewall grout outlet is a strip.The pulp-inlet pipe bottom is furnished with the cavity body of falling a rectangular pyramid agitator tank,
Pulp-inlet pipe top connects air inlet pipe, and air inlet pipe is provided with gate valve.Be provided with three layers of screen cloth of upper, middle and lower in the flotation cell body, mesh size is 20mm.The height of flotation liquid level is regulated gate valve control by moving up and down liquid level regulation apparatus.
The utility model only relies on flowing of ore pulp just can obtain needed inflation of flotation and agitating function, thereby having changed traditional flotation device need rely on the power impeller to rotate and acquisition needed inflation of flotation and agitating function, thereby also saved bubble generator, can gassing generator clogging.
Advance slurry: utilize the discrepancy in elevation, ore pulp is fed the simple unpowered flotation device pulp-inlet pipe, reach the purpose that pressure is given the ore deposit.
Air-breathing: after ore pulp added pulp-inlet pipe, ore pulp passed through from the pulp-inlet pipe road at a high speed, and when ore pulp flowed in ore pulp pipe, the air that can drive in the pipe flowed together, produced negative pressure in the pulp-inlet pipe thereby make.At this moment, air can be pressed into pulp-inlet pipe from air inlet pipe, and is mixed into the flotation zone with ore pulp, and the air inlet size is controlled by the gate valve on the air inlet pipe.
Stir: swiftly flowing ore pulp and AIR MIXTURES are passed through pulp-inlet pipe turbination sidewall length bar shaped grout outlet to ejection all around, after the ore pulp of ejection collides and stirs tank wall, because the effect of counter-force, ore pulp can rebound to the cone center, can form one turbulent flow this moment in cone, thereby reach the effect of stirring.
Liquid level is regulated: move up and down the adjusting gate valve, reach the height of regulating the flotation liquid level.
After selected ore pulp and medicament fully stir, utilize the discrepancy in elevation that ore pulp is fed the stock inlet of simple unpowered flotation device and flow at high speed in ore pulp pipe, when ore pulp is swiftly flowing, in ore pulp pipe, produce negative pressure, cause air to enter and be blended in one through ore pulp outlet ejection with ore pulp from air entry, ore pulp after the ejection is because the effect of pressure, be sprayed on and produce bounce-back on the stirring tank wall of taper, form the ore pulp turbulent flow, reach stirring action, make the hydrophobicity ore particle can have adequate time to contact with bubble.Bubble floating after the mineralising filters macrofoam (non-mineralising bubble) by three layers of screen cloth in floating-upward process, and the mineralising bubble rises to mineral syrup liquid and forms one deck mineralized froth layer at liquid level.By the liquid level adjusting device, make the mineralized froth floor height flow out cell body and collect in foam outlet, the underflow product then flows out from the tailings discharging mouth.
