Abstract
The utility model relates to a large-diameter floatation column middling swirling and tailing swirling discharging device and belongs to the technical field of floatation. The large-diameter floatation column middling swirling and tailing swirling discharging device is composed of a column, an upper conical barrel, a middle conical barrel, a lower conical barrel, middling feed pipes, a bottom cone, a tailing discharge pipe and a tailing discharge barrel. The upper conical barrel is connected with the upper portion of the middle conical barrel. The upper portion of the lower conical barrel is connected with the lower portion of the middle conical barrel. The lower portion of the lower conical barrel is connected with the column. The middling feed pipes are connected with the column. One end of the tailing discharge pipe is connected with the column and the bottom cone. The other end of the tailing discharge pipe is connected with the tailing discharge barrel. The middling feed pipes are connected with the wall of the column at a certain tangential included angle and a certain tangential elevation angle. The tailing discharge pipe is connected with the bottom cone at a certain tangential included angle and a certain tangential elevation angle. The large-diameter floatation column middling swirling and tailing swirling discharging device has the advantages that the swirling floatation effect of middlings is good, tailings can be discharged in time, and the problems that the tailing discharge pipe is blocked and tailing dead zones exist at the bottom of the column are solved.
Description
Affiliated technical field
The utility model relates to a kind of major diameter flotation column chats swirl-flow devices and mine tailing eddy flow drawing mechanism, belongs to flotation technology field.
Background technology
The flotation column chats swirl-flow devices using is at present applied on major diameter flotation column, mainly has the following disadvantages: near column side wall, ore pulp adverse current collision opportunity is few chats cyclone flotation weak effect.
The flotation column mine tailing drawing mechanism technology of using is at present relatively ripe, and primary structure is directly to connect one or two discharge nozzle on the sidewall of cylinder bottom, relies on cylinder ore pulp self pressure to flow automatically to mine tailing bucket and discharges.This structure applications is on major diameter flotation column, and bottom discharge pipe easily stops up on the one hand; On the other hand, there is " dead band " in cylinder bottom mine tailing, and part mine tailing can not be discharged in time, directly affects flotation effect.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of major diameter flotation column chats swirl-flow devices and mine tailing eddy flow drawing mechanism are provided.
A kind of major diameter flotation column chats swirl-flow devices described in the utility model and mine tailing eddy flow drawing mechanism, be comprised of cylinder, upper conical-tube, middle cone cylinder, slower conical tube, chats feeding pipe, base cone, mine tailing discharge nozzle, mine tailing drainage cradle; Upper conical-tube is connected with middle cone cylinder top, slower conical tube top is connected with middle cone cylinder below, and slower conical tube below is connected with cylinder, and chats feeding pipe is connected with cylinder, mine tailing discharge nozzle one end is connected with cylinder and base cone, and the mine tailing discharge nozzle other end is connected with mine tailing drainage cradle.
The Main Function of described upper conical-tube: the middle ore pulp that eddy flow rises, under the guide effect of upper conical-tube, to column side wall diffusion, with the abundant adverse current collision of the middle ore pulp declining mineralising, has improved the rate of recovery of flotation concentrate, and cyclone flotation is effective.
Described chats feeding pipe, is connected with cylinder wall along certain tangential angle and the elevation angle.The Main Function of described chats feeding pipe: evenly ejecting from chats feeding pipe by certain pressure, certain angle, ore pulp is after dispersing, a part is ejected on middle cone cylinder inwall, form cyclone flotation, make lighter particle increase rapidly, and make heavier particle be dropped rapidly to cylinder bottom to become mine tailing, improved the efficiency of separation; Another part ore pulp is directly injected on column side wall after upper conical-tube guiding, with the abundant adverse current collision of the middle ore pulp declining mineralising, has further improved the rate of recovery of flotation concentrate, and cyclone flotation is effective.
The upper shed of described base cone is connected with cylinder wall, and under shed is connected with cylinder base plate.The Main Function of described base cone: reduce bottom storage area, improve the storage height of mine tailing, be convenient to mine tailing and discharge in time; Base cone is arranged on the downside of chats feeding pipe, drops to the mine tailing of cylinder bottom by certain angle spiral, forms eddy flow state on base cone, has solved cylinder bottom mine tailing " dead band " problem.
Described mine tailing discharge nozzle, is connected with base cone along certain tangential angle and the elevation angle.Its Main Function: mine tailing discharge nozzle is connected with base cone by the elevation angle, has solved mine tailing discharge nozzle blockage problem; Mine tailing discharge nozzle tangentially angle is connected with base cone, mine tailing discharge nozzle entrance axis direction is consistent with the mine tailing eddy flow direction of eddy flow state, mine tailing flows automatically to the timely eddy flow of mine tailing bucket by cylinder ore pulp self pressure and discharges, and form eddy flow passage, further solved mine tailing discharge nozzle blockage problem and cylinder bottom mine tailing " dead band " problem.
The beneficial effects of the utility model are: chats cyclone flotation is effective; Mine tailing is discharged in time, has solved mine tailing discharge nozzle blockage problem and cylinder bottom mine tailing " dead band " problem.
Accompanying drawing explanation
Figure is structural representation of the present utility model,
In figure: 1-cylinder, 2-upper conical-tube, 3-middle cone cylinder, 4-slower conical tube, 5-chats feeding pipe, 6-base cone, 7-mine tailing discharge nozzle, 8-mine tailing drainage cradle.
The specific embodiment
As shown in the figure: middle ore pulp enters the bottom of cylinder 1 by chats feeding pipe 5, after dispersing along slower conical tube 4, a part is ejected on middle cone cylinder 3 inwalls, lighter particle rises rapidly, heavier particle is dropped rapidly to cylinder bottom becomes mine tailing, on base cone 6, form eddy flow state, and discharge from flowing to the timely eddy flow of mine tailing drainage cradle 8 by mine tailing discharge nozzle 7; Another part ore pulp is ejected on column side wall through upper conical-tube 2, with the abundant adverse current collision of the middle ore pulp declining mineralising.
