Description
Technical field
The invention belongs to technical field of magnetic separation equipment, more particularly to a kind of mine tailing in-flow magnetic separation sorted for magnetic iron ore
Post.
Background technology
Column magnetic separator is, using the intermittent low-intensity magnetic field in spiral winding, magnetic mineral is reunited and accelerate to sink, while utilizing
The intergrowth and gangue that ascending current power will be mixed in magnetic iron ore monomer particle are rinsed away, and concentrate product are improved so as to reach
The purpose of position.The commercial Application of column magnetic separator is primarily present two problems at present, and one is the field weakening in the middle part of spiral cast magnetic system,
So as to reduce the possibility that micro fine particle magnetite in the region is captured, tailings grade rising is easily caused, concentrate metal is returned
Yield reduction；Two is that by solenoidal field, periodically alternately change makes magnetic mineral produce "-dispersion-of reuniting is reunited " to column magnetic separator
And flow gradually downward, while the intergrowth that will be exposed in dispersion process using ascending current and gangue mineral are developed
And the overflow area to top is carried as mine tailing, the assorting room water consumption which results in column magnetic separator is excessive, and average treatment is every
Ton needs more than water consumption 2-4 tons to ore deposit.
The content of the invention
The problem above according to present in column magnetic separator application of the invention, there is provided a kind of tailings grade is low, and water consumption is few
Mine tailing in-flow column magnetic separator.
The object of the present invention is achieved like this.
It is according to a kind of mine tailing in-flow column magnetic separator of the invention including outer barrel, ore pulp mine-feeding equipment, sorting cylinder, tangential
Feed pipe, mine tailing overflow mechanism, concentrate pipe, magnetic system and electric control gear, it is characterised in that：
Described ore pulp mine-feeding equipment is uniformly arranged on mine-separating disk bottom, and connect with mine-separating disk by opened type mine-separating disk
Multiple point pipe constituted, the middle part of sorting cylinder is stretched into point pipe bottom, and the top of described mine-separating disk is open
Design, the round table-like guide ring at middle part forms mine-carrying groove with the side of inverted cone-shaped；
Described magnetic system is solenoid coil, is nested in the outside of sorting cylinder；
To be placed in sorting cylinder, edge sorts the axially arranged mine tailing inner flow tube of cylinder center to the mine tailing overflow mechanism,
The top of described mine tailing inner flow tube is connected with the guide ring bottom in the middle part of mine-separating disk, and outside is interior with sorting cylinder by support
Wall is fixedly connected, and the bottom of mine tailing inner flow tube inclines the outside that sorting cylinder is extended to after 45 °；It is equal at the top of mine tailing inner flow tube
It is even to be provided with mine tailing overfall, in the end of mine tailing inner flow tube, mine tailing flow control valve is set；
Described tangential feed pipe is located at the bottom of last solenoid coil from top to bottom, and feedwater direction is justified with sorting
Drum outer wall is tangent, and feed water brake is provided with tangential feed pipe；
Described concentrate pipe is connected with the base cone of sorting cylinder, and concentrate flow control valve is set on concentrate pipe；
Described solenoid coil, mine tailing flow control valve, feed water brake and concentrate flow control valve with
Electric control gear is connected.
Preferably, the bottom of described mine tailing overfall is about 0.3-1 higher than the distance at the top of first solenoid coil
Coil height again, the number of described mine tailing overfall is 2-4.
Preferably, the spacing of described solenoid coil adjacent windings is 0.5-1 times of coil height, and number of coils is 4-
9.
It is an advantage of the invention that：
Flow pattern column magnetic separator reduces with the big defect of water consumption cleverly traditional column magnetic separator sorting area middle part magnetic field in mine tailing
With reference to simultaneously complementary, the mine tailing inner flow tube of mine tailing overfall is included in the middle part setting of column magnetic separator, both avoided column magnetic separator sorting area
Middle part magnetic field reduces the defect for causing fine-particle minerals to be lost in, and needs consumption a large amount of while also overcoming mine tailing in traditional column magnetic separator
Ascending water could " following current and on " enter the problem of overflow launder, the water consumption of column magnetic separator can be greatly reduced.
Brief description of the drawings
Fig. 1 is the structural representation of flow pattern column magnetic separator in mine tailing.
Fig. 2 is the top view of flow pattern column magnetic separator in mine tailing.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of mine tailing in-flow column magnetic separator of the invention, including outer barrel 13, ore pulp mine-feeding equipment,
Sorting cylinder 1, tangential feed pipe, mine tailing overflow mechanism, concentrate pipe, magnetic system and electric control gear, it is characterised in that：
Described ore pulp mine-feeding equipment by opened type mine-separating disk 12, the bottom of mine-separating disk 12 being uniformly arranged on, and with a point ore deposit
The multiple point pipe 9 of disk connection is constituted, generally 4-6, and the middle part of sorting cylinder 1 is stretched into point bottom of pipe 9, described
The top of mine-separating disk 12 be open design, the round table-like guide ring 11 at middle part forms mine-carrying groove with the side of inverted cone-shaped；
