Summary of the invention
For above-mentioned situation, for overcoming prior art defect, the object of the utility model is just to provide a kind of bauxite forward flotation scavenger flotation cell two-way mineralising combination unit, can effectively solve in flotation operation process, roughly select wake flow alumina content large, the operation alumina recovery rate of scavenger flotation cell is low, scans wake flow alumina content high, cause product not up to standard, the problem that flotation effect is poor.
The technical scheme that the utility model solves is, comprise and roughly select wake flow charging aperture, roughly select wake flow dashpot, slide valve, mineralization device, pulp distributer, scavenger flotation cell and scavenger flotation circuit pump, roughly select wake flow charging aperture respectively with the first slide valve, second slide valve is connected, first slide valve with roughly select wake flow dashpot and be connected to form main road structure, second slide valve forms bypass structure through the inlet communication of pipeline and mineralization device, the bottom discharge pipe roughly selecting wake flow dashpot inserts in the pipeline of scavenger flotation circuit pump inlet, scavenger flotation circuit delivery side of pump is connected with the import of pulp distributer, pulp distributer has multi-way outlet pipe, the outer end of outlet is connected with the mineralising organ pipe extend in scavenger flotation cell downwards, all there are two arms in inverted V-shaped the lower end of each mineralising organ pipe, the outlet of mineralization device is inserted into the outlet top of pulp distributer, the outlet at bottom pipe of scavenger flotation cell is communicated with the inlet tube of scavenger flotation circuit pump.
The utility model substantially increases ore concentration of bauxite alumina recovery rate, reduces Tailings Slurry alumina content, is the innovation on bauxite flotation equipment.
Accompanying drawing explanation
Fig. 1 is structural front view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
Provided by Fig. 1, the utility model comprises roughly selects wake flow charging aperture, roughly select wake flow dashpot, slide valve, mineralization device, pulp distributer, scavenger flotation cell and scavenger flotation circuit pump, roughly select wake flow charging aperture 1 respectively with the first slide valve 4, second slide valve 3 is connected, first slide valve 4 with roughly select wake flow dashpot 2 and be connected to form main road structure, second slide valve 3 forms bypass structure through the inlet communication of pipeline and mineralization device 5, the bottom discharge pipe roughly selecting wake flow dashpot inserts in the pipeline of scavenger flotation circuit pump 9 import, scavenger flotation circuit delivery side of pump is connected with the import of pulp distributer 6, pulp distributer has multi-way outlet pipe, the outer end of outlet is connected with the mineralising organ pipe 7 extend in scavenger flotation cell 8 downwards, all there are two arms in inverted V-shaped the lower end of each mineralising organ pipe, the outlet of mineralization device 5 is inserted into the outlet top of pulp distributer, the outlet at bottom pipe of scavenger flotation cell is communicated with the inlet tube of scavenger flotation circuit pump 9.
Described mineralising organ pipe 7 and arm connect and compose " Y " shape structure of handstand.
Described mineralization device 5 is that each outlet communicates with each outlet of pulp distributer respectively by two export mixes on steel pipe and steel pipe sidewall.
The quantity of described mineralization device 5 is 1/4 of arm quantity.
Described wake flow dashpot of roughly selecting is dashpot.
The utility model is also not limited in above-described embodiment, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
Service condition of the present utility model is: in ore concentration of bauxite process, old process is to be roughly selected wake flow and enters and roughly select wake flow dashpot 2 and enter pulp distributer 6 by scavenger flotation circuit transport pump in the lump with scavenger flotation cell 8 underflow and enter in mineralising organ pipe 7, be input to again in scavenger flotation cell 8 by mineralising organ pipe 7 and carry out mineralising operation, when the alumina content roughly selecting wake flow through assay reaches more than 48%, now roughly select wake flow alumina content higher, show that initial separatory cell separating effect is poor, now should enable bypass flow process, first slide valve 3 is opened, then slide valve 4 is closed, roughly select wake flow to be assigned in each mineralising organ pipe 7 through mineralization device 5 and to carry out mineralising operation.
