Description
The present invention relates to a kind of flotation device, be applicable to sorting and sewage disposal of metal, nonmetallic mineral.
At present, both at home and abroad the flotation device kind of using that adds inflation is more, the reasonable Dao Er-Ao Liwo flotation device that the U.S. is arranged of performance wherein, the OK flotation device of Finland, the KYF flotation device of China.It as the number of patent application of announcing in Patent Office of the People's Republic of China on October 12nd, 1,988 87102140.4 patent documentation.Because adding air flotation machine has the part low-pressure air to enter in the impeller cavity, offset the negative pressure that in impeller cavity, forms by the impeller rotation, so above-mentioned flotation device all can not self-suction feeding and chats, need step configuration between each operation of flotation flowsheet, chats returns needs the adapted foam pump.
But the inflation agitation impeller flotator that the purpose of this invention is to provide horizontal arrangement between a kind of flotation flowsheet operation, the saving energy, overall economic efficiency reasonable energy self-suction feeding and chats.
To achieve these goals, the present invention by the following technical solutions.
The flotation device of self-suction feeding and chats, comprise motor, transmission device, bearing body, crossbeam, air control valve, hollow spindle, central tube, impeller, stator, cell body, it is characterized in that: a impeller can be prevented that impeller disk and being located at that low-pressure air enters pulp absorbing area from sucking to the blade of ore deposit and chats and being located at the lower blade that works the effect of mixing below the impeller disk above the impeller disk and formed by the band centre bore that is connected with the hollow spindle bottom by flange; B is provided with the disc cover plate that is connected with the central tube lower end at distance impeller blade upper limb 5～15mm place; C is provided with top in the hollow spindle outside and is connected with the bearing body bottom, and the bottom is connected with central tube top, and the position on the L-L mineral syrup liquid is provided with the tube connector of steam vent; D is provided with an end and is connected with central tube, and the chats recurrent canal that the other end is connected with cell body is connected with central tube with an end, the other end and the mineral-feeding pipe of being connected for the ore deposit case.
The impeller blade adopt radial straight blades or with the straight blades that radially becomes 30 ° of angles of hypsokinesis to the 30 ° of angles of leaning forward, the number of blade is the 4-8 sheet.
The impeller lower blade adopts from 30 ° of angles of hypsokinesis blade radially, and the inner edge of its blade becomes 80 °～120 ° angles or one-tenth parabola or one-tenth circular arc line with the blade base.
The external diameter of cover plate is equal to or greater than impeller diameter, the impeller diameter less than 105%.
Owing to adopted technique scheme, the present invention compared with the prior art can self-suction feeding and chats, but horizontal arrangement between the flotation flowsheet operation has been saved the foam pump that chats returns usefulness, and floor space is little; Have that the air dispersion ability is strong, solid particle suspension situation is good, sorting index is high, power consumption is low, easy to operate, advantage that overall economic efficiency is high.

Below in conjunction with the accompanying drawing illustrated embodiment, the present invention is further described.
The flotation device of self-suction feeding and chats comprises motor (11), transmission device (12), bearing body (8), crossbeam (9), air control valve (10), hollow spindle (7), central tube (5), impeller (2), stator (3), cell body (1), it is characterized in that: impeller can be prevented that low-pressure air from entering the impeller disk (18) of pulp absorbing area and being located at can suck the blade (19) of giving ore deposit and chats above the impeller disk and be located at the lower blade (17) that works the effect of mixing below the impeller disk and formed by the band centre bore that is connected with the hollow spindle bottom by flange (16); Be provided with the disc cover plate (4) that is connected with the central tube lower end with bolt (25) at distance impeller blade upper limb (24) 5～15mm places; Be provided with top in the hollow spindle outside and be connected with the bearing body bottom with bolt, position that the bottom is connected with central tube top with bolt and on the L-L mineral syrup liquid is provided with the tube connector (6) of steam vent (26), utilizes tube connector to fix central tube and cover plate; Be provided with an end and be connected with central tube, the chats recurrent canal (14) that the other end is connected with cell body is connected with central tube with an end, the other end and the mineral-feeding pipe (15) of being connected for the ore deposit case.
Blade adopt radial straight blades or with the straight blades that radially becomes 30 ° of angles of hypsokinesis to the 30 ° of angles of leaning forward, the number of blade is the 4-8 sheet.
Lower blade adopts from 30 ° of angles of hypsokinesis blade radially, and the inner edge of its blade (22) becomes 80 °～120 ° angles or one-tenth parabola or one-tenth circular arc line with blade base (21).The centre bore of impeller disk makes to place the usefulness of air distributor (13).
The external diameter of cover plate is equal to or greater than impeller diameter, the impeller diameter less than 105%.
During flotation device work, motor is by transmission device and the rotation of hollow spindle impeller, ore pulp is from all around between bottom land, impeller lower blade inner edge intake impeller lower blade in the cell body, the low-pressure air that while is fed by the outside, enter in the air distributor in the impeller cavity by crossbeam, air control valve, hollow spindle, aperture from the air distributor periphery enters between the impeller lower blade again, and ore pulp and air are discharged by impeller lower blade outer rim (20) after fully mixing between the impeller lower blade.Because the effect of impeller disk, ore pulp, air and gas liquid mixture between the impeller lower blade can not be entered between the impeller blade, and the impeller rotation, under the acting in conjunction of cover plate and central tube, in the impeller blade, produce negative pressure, make the chats foam and flow in the central tube by middle pipe and mineral-feeding pipe, enter between the impeller blade to the ore deposit, broken by the chats foam and the steam vent of gas on tube connector that produce discharged.The chats that ore pulp, air mixture and the impeller blade outer rim (23) of being discharged by impeller lower blade outer rim discharged, give the ore deposit after being installed in the stator current stabilization and orientation around the impeller, enter into main body ore pulp in the cell body, mineral laden bubble rises to the ore pulp surface and forms froth bed, an ore pulp part turns back between the impeller lower blade and recycles, and another part enters down by opening on the cell body that groove sorts again or discharges as a certain final products.
