pipeline and different valves, is shown in Figure 12.Collecting tank 13 is by collecting Cell wall 13a, collecting tank slot bottom 13b and fine fodder discharge outlet 13d composition, are shown in Figure 14 a, Figure 14 b；Collect cell wall 13a and collecting tank slot Bottom 13b collectively constitutes the staving at oblique bottom, flotation cell mounting hole 13c is equipped in the middle part of collecting tank slot bottom 13b, for being sleeved on flotation The periphery slot outer wall 14a, the oblique bottom design of collecting tank slot bottom 13b for convenience of fine fodder centralized collection, receiving by fine fodder discharge outlet 13d setting Collect the oblique bottom least significant end of slot slot bottom 13b.Flotation cell 14 is to see Figure 13 a~13c with staving with dissection, 14b barrels of flotation cell interior bucket Bottom is the inverted conical bodily form, and there are tailing discharge outlet 14i, outside welding tailing delivery pipe 14g in bucket bottom center；Flotation cell outer wall 14a For cylinder, the opposite upper and lower parts of side wall are respectively welded flotation cell heat preservation water outlet pipe 14d, flotation cell heat preservation water inlet pipe 14f, flotation cell heat preservation water inlet pipe 14f are also connected with flotation cell heat preservation inlet water solenoid valve 14k；Seal ring 14j on flotation cell heat preservation sandwich layer It is intubated 14c towards flotation cell temperature sensor is welded on the inside of interlayer, it is upper and lower in flotation cell outer wall 14a and flotation cell interior bucket 14b End is integral with seal ring 14j on flotation cell heat preservation sandwich layer and flotation cell heat preservation sandwich layer lower seal ring 14l sealing welding respectively, intermediate shape At heat preservation water interlayer；Air supply pipe 14e exists through the bottom flotation cell outer wall 14a and flotation cell interior bucket 14b bottom sidewall sealing welding On the two.Collecting tank 13 is sleeved on 14 top of flotation cell, sees Figure 15, and the two is integrally welded.For limiting in flotation cell 14 29 structure of false bottom in pulp flow direction: see Figure 22 a, Figure 22 b, false bottom 29 is by diversion pipe 29a, vacation bottom fixed plate 29b and false bottom Pillar 29c is coupled one composition；False bottom fixed plate 29b is Circular Plate, the water conservancy diversion that center has diameter equal with diversion pipe 29a internal diameter Diversion pipe 29a is welded around deflector hole 29d in hole 29d, Circular Plate side, and equally distributed false bottom pillar is welded on another side ring surface 29c；Diversion pipe 29a nozzle diameter is less than impeller feed inlet 26e, as close possible to guaranteeing through diversion pipe 29a's both when installation Slurry and air fully enter in the cage body of impeller 26, agitated to collide, throw away with air.See Figure 17 a~17d, 26 knot of impeller Structure: impeller 26 is integrally made of impeller fixed plate 26a, impeller blade 26b, vane ring 26c connection, impeller fixed plate 26a Impeller fixing threaded hole 20c on specification and thereon equally distributed impeller fixation hole 26d, with the fixation impeller plate 20b of main shaft 20 It is corresponding；Impeller fixed plate 26a and vane ring 26c are separately fixed at the both ends of each impeller blade 26b, make impeller integral into Cage body structure；Vane ring 26c centre bore is impeller feed inlet 26e, and the slurry and air of the rotation sucking of impeller 26 are through this mouth It is thrown away into cage body inside configuration, then by the centrifugal force that the rotation of impeller 26 generates.Main shaft 20 is for flotation motor 10 and impeller 26 It connects between the two, sees Figure 16 a~16c, there is fixed impeller plate 20b in the one end main shaft axis body 20a, and the two processing is integral；It is fixed There is impeller fixing threaded hole 20c at the center impeller plate 20b, for fixing impeller 26.See that Figure 21 a, Figure 21 b, dispersion cover 28 are truncated cone-shaped Cylinder, rotary table rule of surface is distributed circular dispersion hole 28a, rotary table overlooks the welding dispersion of inner ring top horizontal and covers fixed ring flat-plate 28b, Fixed ring flat-plate 28b specification and thereon equally distributed dispersion cover fixation hole 28c are covered in dispersion, solid with the dispersion cover and stator of column 21 Determine dispersion cover on flange 21c and stator fixing hole 21g is corresponding, it is dispersion cover spindle hole that fixed ring flat-plate 28b inner hole is covered in dispersion 28d, dispersion cover 28 for further dispersing and reducing because impeller 26 rotates flowing of the slurry driven after stator hole 27a is thrown away Direction and speed guarantee liquid level stabilizing in flotation cell 14.Stator 27 is circular cylinder body, sees that Figure 20 a, Figure 20 b, rule of surface are erected Oval stator hole 27a is set, top horizontal welds the fixed ring flat-plate 27b of stator；Stator hole 27a is that impeller 26 throws away the logical of slurry Road influences the size of flotation froth；The specification of the fixed ring flat-plate 27b of stator and thereon equally distributed stator fixing hole 27c, and it is perpendicular The dispersion cover of cylinder 21 is corresponding with the dispersion cover on stator mounting flange 21c and stator fixing hole 21g, and centre bore is stator main shaft Hole 27d；Stator 27 is used to stablize the foam on 14 top of flotation cell, prevents ore pulp to the disturbance of froth bed, generates impeller 26 Vortex forms stable mineral syrup liquid far from froth zone, can also protect impeller 26, is easier the starting of flotation motor 10.
