Spraying tubes are arranged in an ore unloading area, so that ore concentrate sundries can be removed and the ore concentrate grade can be improved. The invention also has the characteristics of simple and reasonable structure, simple and convenient operation, long service life and the like.
Description
Technical field
The present invention relates to a kind of efficient magnetic separation separation equipment technical field, specifically a kind of trough body for high-efficiency permanent magnet drum magnetic separator.
Background technology
As everyone knows, the magnetic separation separation equipment is that the mine ferrous metal sorts the important separation equipment in the process, and the magnetic separation separation equipment of mine use at present mainly contains two kinds from structure, and a kind of is the disc type magnetic separation, and another kind is the cartridge type magnetic separation.Along with the continuous development of science and technology, for enhancing productivity, large-scale magnetic separation separation equipment maximizes day by day, and at the designed professional magnetic separator performance of magnetic concentration working environment also constantly perfect.Requirement at the high-efficiency permanent-magnet drum type magnetic separator sorting operation, need darker magnetic field depth of interaction gradient height be arranged scanning the district, guarantee that with this it finishes the recovery fully to strongly magnetic mineral under big flow rate condition, and permanent-magnet drum type magnetic separator cell body in the market, because also there is defective in self structure, as: at the requirement of high-efficiency permanent-magnet drum type magnetic separator sorting operation, the ore pulp throughput is at 800m
3～1200m
3/ h, the big cornerite of corresponding device, the long characteristic that sorts band dispose the time of staying that high downflow weir increases ore pulp; While concentrate in sorting operation is mingled with comparatively obvious, need handle being mingled with phenomenon, reduces to be mingled with the raising concentrate grade.
Summary of the invention
The purpose of this invention is to provide a kind of trough body for high-efficiency permanent magnet drum magnetic separator that has coarse granule tap and concentrate spray equipment.
The object of the present invention is achieved like this: it includes the cell body that top, a side brings ore deposit import and outlet of magnetic tape trailer ore deposit, bottom and corresponding setting with high-efficiency permanent-magnet drum, this cell body is half adverse current form, it is characterized in that: the bottom surface in cell body is provided with and the ore deposit inlet of being connected for the ore deposit import, with give the cell body of ore deposit import homonymy in slope be provided with the overfall that is connected with the mine tailing outlet, in the cell body of overfall bottom, also be provided with the coarse granule tap that is connected with the mine tailing outlet; Also be provided with the concentrate outlet with the cell body slope top of giving import opposite flank, ore deposit, be evenly distributed with the spray equipment that is directly injected on the high-efficiency permanent-magnet drum on the slope in the cell body between concentrate outlet and overfall horizontal plane.
The present invention is mingled with phenomenon for eliminate concentrate in the magnetic separation process, then be evenly distributed with the spray equipment that is directly injected on the high-efficiency permanent-magnet drum on the slope in the cell body between concentrate outlet and overfall horizontal plane, spray equipment is made up of not magnetic stainless steel pipe and nozzle, and the spray operation has cleaning pressure and even spray in axial direction.
The present invention comprises that also height of weir plate scope vertical between cell body bottom and the overfall is at 180～250 millimeters.
Cell body of the present invention the disk pack angle of the corresponding permanent-magnetic cylindrical that is provided with between 120 °～140 °.
Structure of the present invention is half adverse current form, and the ore pulp handling capacity is at 800m
3～1200m
3/ h can satisfy the requirement of the big flow of magnetic concentration working fully, has carried out particular design at operating feature simultaneously.
This cell body by austenite not magnetic stainless steel be welded.Unload territory, mining area front end and be provided with spray equipment, be made up of not magnetic stainless steel pipe and nozzle, feed the water under high pressure of 0.1MPa～0.2MPa during work in the pipe, water under high pressure penetrates via nozzle, in axial direction uniformly concentrate is washed, to realize alleviating the phenomenon that concentrate is mingled with.
The height of weir plate H of cell body is that the permanent-magnetic cylindrical magnetic that basis cooperates with it is that cornerite designs with the selection that sorts the band wrap angle sigma.The disk pack angle of permanent-magnetic cylindrical is between 120 °～140 °, and the cell body height of weir plate of Pei Heing sorts the band cornerite between 70 °～90 ° at 180～250mm with it.
The present invention has following advantage: i.e. overflow height of weir, sort belt length, and can prolong the sorting time.And have the preferential tap of coarse granule, can prevent effectively that the stifled ore deposit of cell body phenomenon from taking place.Shower is set unloading the territory, mining area, removes concentrate and be mingled with, improve concentrate grade.The present invention also has points such as simple and reasonable, easy and simple to handle, long service life.
Description of drawings
Fig. 1 is a structural representation sketch of the present invention;
Fig. 2 is the stereochemical structure simplified schematic diagram of Fig. 1.
Below in conjunction with accompanying drawing and by example the present invention is described in further detail; but following example only is the present invention's example wherein; the rights protection scope of not representing the present invention and being limited, the scope of the present invention is as the criterion with claims.
The specific embodiment
Example 1:
Shown in Fig. 1-2,1 among the figure be top, a side bring ore deposit import 4 and magnetic tape trailer ore deposit, bottom outlet 7 and with the cell body 1 of high-efficiency permanent-magnet drum 2 corresponding settings, this cell body 1 by austenite not magnetic stainless steel be welded, form is half adverse current form; Bottom surface in cell body is provided with and the ore deposit inlet 8 of being connected for ore deposit import 4, with give the cell body of ore deposit import homonymy in slope be provided with the overfall 5 that is connected with the mine tailing outlet, in the cell body of overfall bottom, also be provided with and the mine tailing outlet 7 coarse granule taps 6 that are connected; Also be provided with concentrate outlet 11 with the cell body slope top of giving import opposite flank, ore deposit.In addition, 3 among the figure is the magnetic system in the permanent-magnetic cylindrical.
The height of weir plate scope is at 180mm～250mm, and the disk pack angle of permanent-magnetic cylindrical is between 120 °～140 °, and sorting the band cornerite is 70 °～110 °, and the ore pulp handling capacity is 800m
3～1200m
3/ h, the suitable concentration of handling ore pulp is 10%～40%, sorting granularity is 0mm～3mm.Sort the overfall below the preferential tap of coarse granule is set, bulky grain is preferentially discharged thus, avoids stifled ore deposit, cell body bottom.
Be evenly distributed with the spray equipment 10 that is directly injected on the high-efficiency permanent-magnet drum on the slope in the cell body between concentrate outlet 10 and overfall 5 horizontal planes (being spillwag chute 9), spray equipment 10 is made up of the nozzle of magnetic stainless steel not, feed the water under high pressure of 0.1MPa～0.2MPa during work in the pipe, water under high pressure penetrates via nozzle, in axial direction uniformly concentrate is washed, to realize alleviating the phenomenon that concentrate is mingled with, improve concentrate grade.This accompanying drawing is an example with 130 ° at permanent-magnetic cylindrical disk pack angle, and Dui Ying cell body height of weir plate H is 200mm～220mm with it, and sorting the band wrap angle sigma is 75 °～80 °, can satisfy the sorting operation requirement fully.
The large granular materials of infiltrating in the ore pulp can preferentially be discharged via coarse granule tap 6 (see figure 2)s via sorting band during the traffic zone, prevents that large granular materials from causing cell body to stop up in the cell body bottom deposit.
