Abstract
The invention relates to a middling cyclone device and tailing cyclone discharging device for a large-diameter flotation column and belongs to the technical field of flotation. The middling cyclone device and tailing cyclone discharging device for the large-diameter flotation column is formed by a column body, an upper conical drum, a middle conical drum, a lower conical drum, a middling charging pipe, a bottom cone, a tailing discharging tube and a tailing discharging barrel; the upper conical drum is connected with the upper part of the middle conical drum; the upper part of the lower conical drum is connected with the lower part of the middle conical drum; the lower part of the lower conical drum is connected with the column body; the middling charging pipe is connected with the column body; one end of the tailing discharging pipe is connected with the column body and the bottom cone while the other end is connected with the tailing discharging barrel; the middling charging pipe is connected with the wall of the column body along a certain tangential included angle and elevation angle. The tailing discharging pipe is connected with the bottom cone along a certain tangential included angle and elevation angle. The middling cyclone device and tailing cyclone discharging device for the large-diameter flotation column has the beneficial effects that the middling cyclone floatation effect is good, the tailings can be timely discharged, and the blockage problem of the tailing discharging pipe and dead zone problem of tailings at the bottom of the column body are solved.
Description
Affiliated technical field
The present invention relates to a kind of major diameter flotation column chats swirl-flow devices and mine tailing eddy flow drawing mechanism, belong 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 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 object of the invention is to overcome the deficiencies in the prior art part, 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 of the present invention and mine tailing eddy flow drawing mechanism, be made up 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 under shed and is connected with cylinder base plate with cylinder wall.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 solve mine tailing discharge nozzle blockage problem and cylinder bottom mine tailing " dead band " problem.
The invention has the beneficial effects as follows: 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.
Brief description of the drawings
Figure is structural representation of the present invention,
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.
Detailed description of the invention
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.
