Abstract
The utility model provides a rotor of an inflating mechanical stirring type floatation machine. The rotor of the inflating mechanical stirring type floatation machine comprises a base plate and blades, and is characterized in that the blades are vertically arranged on the base plate, the edges of the blades are provided with a set of transverse notches, notches of the adjacent blades are arranged in a staggered mode, and each blade is provided with a set of through holes. According to the rotor, a power shearing force can be exerted on bubbles, thinner and smaller bubbles can be formed without increasing the revolving speed of the rotor, and the flotation recycling rate of the flotation machine is improved.
Description
Technical field:
The utility model relates to a kind of rotor of inflating mechanical agitation type flotation machine, belongs to preparation equipment technical field.
Background technology:
Flotation device is the visual plant of realizing floatation process, during flotation, ore pulp and floating agent are sent into flotation device after being in harmonious proportion, therein through stirring and inflation, the floating object mineral of wish are attached on bubble and form mineral laden bubble, float to ore pulp surface and form mineralized froth layer, foam scrapes with scraper plate or overflows in certainly excessive mode, obtain froth pulp, but not froth pulp is discharged from bottom land.The quality of flotation technology economic indicator, closely related with the performance of flotation device used.
Good inflation and stirring action, can form froth zone more stably, can continuous operation and to be convenient to regulate be the good necessary condition of flotation device flotation technology index, during the vane rotary of inflating mechanical agitation type flotation machine, in groove ore pulp from surrounding between bottom land is by impeller lower end intake impeller blade, simultaneously, the low-pressure air being fed by air blast is through air channel, air control valve, hollow spindle enters in impeller cavity, ore pulp with air after fully mixing between impeller blade, by impeller first half periphery, discharged, the ore deposit of discharging flows to oblique upper motion, by the stator that is arranged on impeller surrounding oblique upper after stable and orientation, enter into whole trough.Mineral laden bubble rises to trough surface and forms foam, and foam flows in foam tank, and ore pulp returns to impeller district again and recycles, and another part enters lower groove by the opening on groove partition and sorts.As can be seen here, the size of bubble is relevant with the turbulence level of flotation trough inner fluid.General bubble size reduces along with the increase of turbulence level in groove.And along with the raising of the rotating speed of rotors for flotation and reduce, therefore for flotation bubble is reduced, generally take at present to improve the method for the rotating speed of rotors for flotation, but the too high energy consumption that causes of rotating speed is large, and the wearing and tearing of rotor and cover plate strengthen, therefore by changing the structure of flotation device itself, to change the problem of bubble quality urgently to be resolved hurrily.
Summary of the invention:
The purpose of this utility model is that a kind of rotor of inflating mechanical agitation type flotation machine is provided for the problem of above-mentioned existence, can form powerful shear action to bubble, in the situation that not improving rotor speed, be beneficial to the more tiny bubble of formation, be beneficial to the flotation recovery rate that improves flotation device.
Above-mentioned object realizes by following technical scheme:
The rotor of inflating mechanical agitation type flotation machine, comprise chassis and blade, described blade is vertically set on described chassis, and the breach that the edge of described blade has between one group of horizontal breach and adjacent blade is staggeredly set, and has one group of through hole on described blade.
The rotor of described inflating mechanical agitation type flotation machine, is provided with dowel between the blade arranging separately.
The rotor of described inflating mechanical agitation type flotation machine, the aperture of described through hole is 0.5-3mm, the distance between adjacent through hole is 3-15mm.
The rotor of described inflating mechanical agitation type flotation machine, the number of described blade is 6 above even numbers.
Beneficial effect:
1. the breach that the blade edge that the utility model is adjacent has between one group of horizontal breach and adjacent blade is staggeredly set, on described blade, there is one group of through hole, such structure shearing force in the process stirring is large, resistance is little, more be beneficial to and form tiny bubble, flotation effective.
2. between the blade that the utility model arranges separately, be provided with dowel, make its structure more stable, more durable, be beneficial to the service life of Extending Rotor.
3. blade of the present utility model is set to even number, stressed even in the process of rotating, and is beneficial to the stable of flotation liquid level.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
In figure: 1, chassis; 2, blade; 3, through hole; 4, dowel.
The specific embodiment:
Embodiment 1:
As shown in Figure 1, the rotor of the inflating mechanical agitation type flotation machine of the present embodiment, comprise chassis 1 and blade 2, described blade is vertically set on described chassis, the breach that the edge of described blade has between one group of horizontal breach and adjacent blade is staggeredly set, and has one group of through hole 3 on described blade.
The rotor of the inflating mechanical agitation type flotation machine described in the present embodiment, is provided with dowel 4 between the blade arranging separately.Because the edge of blade has the breach of horizontally set, and the staggered layout of the breach between adjacent blade, between the blade therefore arranging separately, be provided with the Stability Analysis of Structures that dowel is more conducive to blade.Certainly the width of reinforcement or the width that diameter is less than breach, so just can play the effect of shearing.
The rotor of the inflating mechanical agitation type flotation machine described in the present embodiment, the aperture of described through hole is 0.5-3mm, the distance between adjacent through hole is 3-15mm.
The rotor of the inflating mechanical agitation type flotation machine described in the present embodiment, the number of described blade is 6 above even numbers.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises by above technical characterictic and is equal to the technical scheme that replacement forms.Unaccomplished matter of the present utility model, belongs to those skilled in the art's common practise.
Claims (4)
