specific Embodiment

[0050] Such as Figure 5 The shown flotation machine impeller 1 is composed of upper and lower vertical sections on the outside and a blade 2 with a cone angle on the bottom inside, a circular impeller disk 3 and a cylindrical air distributor with holes 4, and forms a performance affecting part.

[0051] Such as Figure 6 As shown, the blade 2 has an outer polyline profile 8 , a lower horizontal section 9 , an inner lower cone section 10 and an inner vertical section 11 .

[0052] The outer multi-line profile 8 of the blade 2 is composed of an upper vertical section 8-1, a lower vertical section 8-2 and a middle inclination section 8-3. The upper vertical section 8-1 forms a rectangular performance-influencing portion N1, the vertical height H1 is 5%-20% of the total blade height H, and the radius R1 is equal to the radius R of the impeller. This feature widens the width of the jet flow zone on the upper part of the blade. Because the diameter of the blade is the largest at...

Abstract

The invention discloses a flotation machine impeller for improving the circulation capacity of ore pulp, which comprises an impeller disc, blades and a cylindrical air distributor; The straight section, the inner lower cone section and the lower horizontal section; the air distributor is embedded in the impeller cavity enclosed between the blade and the impeller disc, and the inside of the air distributor has a circular air passage, the bottom of the air distributor and The side walls are respectively provided with air holes; the upper vertical section forms a rectangular performance affecting part; the lower vertical section and the inner lower cone angle section form a similar inverted right-angled trapezoidal performance affecting part; the air distributor and the inner lower cone angle section jointly form a frustum performance influence department. The impeller circulation capacity of the flotation machine is improved, the dispersion effect of mineral particles and air bubbles is improved, the collision probability of particles and air bubbles is increased, and the sorting performance of the flotation machine is improved.

Description

technical field [0001] The invention relates to an impeller of a flotation machine, in particular to an impeller of a flotation machine which improves the circulation capacity of ore pulp. Background technique [0002] Flotation machine is the key equipment to realize mineral flotation separation. The impeller of the flotation machine is the core component of the flotation machine and has multiple functions. The inflatable flotation machine makes the mineral particles evenly disperse and suspend in the flotation machine through the agitation of the impeller. The low-pressure air fed by the external blower turns into a large number of tiny bubbles through the stirring and shearing action of the impeller, and is uniformly dispersed in the flotation machine with the pulp flow. After the mineral particles and air bubbles in the slurry collide and adhere, the final foam product is formed. The ability of the impeller to circulate the slurry is the basis for the uniform dispersi...
