Abstract
The utility model relates to a mixer, particularly a gas-liquid mixer. The gas-liquid mixer comprises a rotating disk and a lamina, the circumference of which is homogeneously distributed on the rotating disk, wherein the rotating disk is of a pan cover shape with the middle part being arched. The rotating disk of a pan cover type is more favorable for prolonging the residence time of gas under the disk so as to be more favorable for reaction of gas and materials, increasing the mixing effect.
Description
Technical field
The utility model relates to a kind of agitator, particularly a kind of gas-liquid mixed agitator.
Background technology
The gas-liquid mixed agitator, gas-liquid mixed as fermentation tank, all be that compressed air is introduced from container bottom, stir through agitator, make the increase that contacts of gas and material, but present gas-liquid mixed agitator is because its rotating disc all is flat, this makes the very fast meeting of gas spread out around rotating disc, make gas very brief with the time of contact of material in whipping process, cause mixing effect not ideal, be unfavorable for the abundant reaction of material and gas, in addition owing to the gas-liquid mixed agitator of tool than the prismatic blade structure, usually it is relatively poor that it holds the gas ability, and bigger blade such as the semi-canal type of curvature, the hyperboloid formula is though that it holds the gas ability is stronger relatively, thereby dispersion and mass transfer effect have been improved, but its shear ability of the agitator of common this blade descends to some extent, is unfavorable for bubble, breaing up of material particles, thus mixing effect influenced.
Summary of the invention
The purpose of this utility model is the deficiency that solves above-mentioned gas-liquid mixed agitator, and provides a kind of mixing effect good gas-liquid mixed agitator.
The purpose of this utility model is achieved by the following technical solution: a kind of gas-liquid mixed agitator, include rotating disc and the circumference uniform distribution blade on rotating disc, and described rotating disc is the middle pot cover shape that arches upward.
The utility model further is set to: the concave surface of described blade is a stress surface, and it has the leading edge of the lordosis that turns up, and the protuberance summit is near rotating disc center one side.
The utility model further is set to again: the leading edge of described lordosis is a triangle.
The utility model further is set to again: described blade is parabolic blade, is the both sides up and down that boundary's branch is positioned at rotating disc with the parabola top, and parabolic upside is longer than downside.
The beneficial effects of the utility model are: the rotating disc of pot cover formula more helps increasing the holdup time of gas under dish, thereby more helps the reaction of gas and material, has increased mixing effect.
Further beneficial effect of the present utility model is: the stress surface leading edge of blade is not straight convex, thereby has increased the shearing force of gas, thereby more helps breaing up of bubble, a material material, has increased mixing effect.

Fig. 2 is the vertical view of Fig. 1
Fig. 3 is the A-A revolved sectional view of Fig. 1
The specific embodiment
Now in conjunction with the accompanying drawings the utility model is further described:
As shown in Figure 1 to Figure 3 as can be known, a kind of gas-liquid mixed agitator of the utility model embodiment, include a kind of gas-liquid mixed agitator, include rotating disc 1 and the circumference uniform distribution blade 2 on rotating disc, described rotating disc 1 is the middle pot cover shape that arches upward, the rotating disc 1 of pot cover formula more helps increasing the holdup time of gas under dish, thereby material and gas are reacted fully.
The concave surface 21 of described blade 2 is a stress surface, and it has the protruding leading edge 3 of turning up, and protuberance summit 31 is near rotating disc center one side.Usually tool is than the gas-liquid mixed agitator of prismatic blade structure; it is relatively poor that it holds the gas ability; and bigger blade such as the semi-canal type of curvature; the hyperboloid formula; though it is stronger relatively that it holds the gas ability; thereby dispersion and mass transfer effect have been improved; but the air and liquid mixer of common this blade construction of tool; its shear ability descends to some extent; be unfavorable for bubble; breaing up of material particles, thus mixing effect influenced, and the edge adopts not straight convex and summit near rotating shaft center in face of the vane stress; the shearing force of blade inboard is strengthened; thereby increased whole agitator, more helped bubble; breaing up of a material material makes mixing effect desirable more; therefore present embodiment adopts this scheme; certainly, if adopt general structure blade as curved leaf; the arrow leaf; straight leaf; oblique leaves etc. are also obviously in this practical protection domain.
Described protruding leading edge 3 is a triangle.Leg-of-mutton protruding leading edge other shape relatively makes manufacturing easier, and can certainly adopt other shape such as quadrangle.
Described blade 2 is parabolic blade, with the parabola top is the both sides up and down that boundary's branch is positioned at rotating disc, parabolic upside is longer than downside, paraboloidal blade is to be bent into the blade that the cross section becomes parabolic shape by sheet material, can reduce the air pocket at blade rear, blade is an asymmetric formula up and down, the blade on top is longer than the blade of bottom, the gas of rising is covered by the linear leaf on top, avoided too early directly the rising of gas to escape from the impeller zone, thereby make the reaction of material and gas more abundant, further improved mixing effect, blade also can adopt common shape, but relatively, adopt parabolic blade better effects if, so present embodiment adopts this class formation.
