Abstract
The invention discloses an inflatable impeller, which comprises an impeller chassis, wherein blades are arranged on the impeller chassis, a cavity is arranged in the center of the impeller chassis, blade air channels and exhaust holes are formed in the blades, the cavity in the center of the impeller chassis is communicated with the blade air channels through the impeller chassis air channels, and the exhaust holes are communicated with the blade air channels. The invention has the following advantages: the impeller is designed into a large blade, the outer side contour line is a curve, and the impeller can form proper stirring intensity at a lower rotating speed, so that the ore pulp surface is stable, and the sorting index of non-metal ores is improved. The side of the impeller is provided with an exhaust hole, and air is thrown out from the exhaust hole on the side by the rotating impeller, so that the device has the advantages of uniform air dispersion, fine and uniform bubbles, good foaming performance, good flotation effect and the like. The impeller integrates stirring and inflation, and has simple structure and low energy consumption.
Description
Technical field
The present invention relates to a kind of impeller.
Background technology
Impeller is that component of machine commonly used is gone up in industry, is widely used, and different applications have different features.Wherein, nonmetallic ore ore dressing and pneumatic flotation cell have particularity, require (1) impeller mixing power moderate, and the ore pulp face is wanted steadily.(2) want big through the ore pulp internal circulating load of impeller, can make the unobstructed suction slurry of flow process.(3) form is reasonable, and is simple in structure, low in energy consumption.(4) have suitable aeration quantity, air dispersion is even, and aeration quantity can be regulated arbitrarily.Present domestic flotation device such as JJF type, XJZ type, SF type, BF type etc., its impeller common characteristic is: from air-breathing, and inspiratory capacity is big, and mixing power is bigger.KYF type inflation mechanical agitation type, HCCX type, YX type flash flotation machine improve to some extent on inflation and frame for movement in addition, have obtained certain effect.But effect is desirable not enough.
Summary of the invention
The object of the invention just is to provide a kind of gas-filled type impeller of better effects if.
The object of the invention can be realized through following measure:
The present invention includes the impeller chassis; The impeller chassis is provided with blade; The center on impeller chassis is provided with cavity; On blade, offer blade air duct and steam vent, the cavity of impeller center chassis is connected with the blade air duct through impeller chassis air duct, and steam vent is connected with the blade air duct.Blade all is positioned at the same side, impeller chassis, also can be positioned at both sides up and down.
Steam vent is one or at least two among the present invention.Blade outboard wheel profile is a curve.
The present invention makes it to have the following advantages owing to adopt impeller inside to offer structures such as air duct and side steam vent:
1, impeller is designed to big blade, and the outboard wheel profile is a curve, can under lower rotating speed, form suitable stirring intensity, makes the ore pulp face steady, has improved the sorting index of nonmetallic ore.
2, impeller side has steam vent, air by the impeller of rotation from the side steam vent throw away advantage such as it is even to have air dispersion, and bubble is thin and evenly, and frothing capacity is good, and flotation effect is good
The impeller collection stirs and aerates one, and simple in structure, energy consumption is low.

The specific embodiment
The present invention does with detailed description below in conjunction with accompanying drawing and embodiment:
As shown in the figure; The present invention includes impeller chassis 1; Impeller chassis 1 is provided with blade 2, and the center on impeller chassis 1 is provided with cavity 3, on blade 2, offers blade air duct 4 and steam vent 5; The cavity 3 of impeller center chassis is connected with blade air duct 4 through impeller chassis air duct 6, and said steam vent 5 is connected with blade air duct 4.This impeller is designed to big blade with impeller blade on to research of flotation machine impeller in the past and flotation kinetics basis, and impeller inside has air duct and side steam vent simultaneously, satisfies the specific (special) requirements of pneumatic flotation cell and nonmetallic ore preparation equipment.
The operation principle of this impeller is: the present invention is according to pneumatic flotation cell and nonmetallic ore ore dressing characteristics; A kind of collection that works out stirs and aerates the one novel impeller is gas-filled type impeller, has satisfied the specific (special) requirements of pneumatic flotation cell and nonmetallic ore preparation equipment.Ore pulp advances pipe entering cell body by the medial compartment of an end during work, when impeller rotates, by between impeller intake impeller blade; The air that is fed by air blast is simultaneously got into the cavity 3 of impeller center chassis by hollow shaft through air control valve; And then through the impeller chassis air duct 6 gets into blade air ducts 4, throw away through steam vent 5 at last, the air that throws away and ore pulp are after fully mixing between impeller blade; Discharge by impeller periphery; The ore pulp of discharging by stator current stabilization and orientation after, be distributed in the whole trough, mineral laden bubble rises to trough surface formation froth bed; An ore pulp part turns back between impeller blade through circulation canal and recycles in the groove, and another part enters into down groove from medial compartment flashboard top and sorts.
As shown in the figure; The present invention includes impeller chassis 1; Impeller chassis 1 is provided with blade 2, and the center on impeller chassis 1 is provided with cavity 3, on blade 2, offers blade air duct 4 and steam vent 5; The cavity 3 of impeller center chassis is connected with blade air duct 4 through impeller chassis air duct 6, and said steam vent 5 is connected with blade air duct 4.Steam vent is one or at least two.
Operation principle is with embodiment 1.
Embodiment 3
As shown in the figure; The present invention includes impeller chassis 1; Impeller chassis 1 is provided with blade 2, and the center on impeller chassis 1 is provided with cavity 3, on blade 2, offers blade air duct 4 and steam vent 5; The cavity 3 of impeller center chassis is connected with blade air duct 4 through impeller chassis air duct 6, and said steam vent 5 is connected with blade air duct 4.
