Abstract

The utility model discloses a centrifugal stirrer. The centrifugal stirrer comprises a driving mechanism and an impeller, wherein the impeller comprises an impeller fixing seat, large blades and small blades; the large blades and the small blades are uniformly distributed on the blade fixing seat at intervals; the blade fixing seat comprises a ring-shaped step surface and a ring side wall; the adjacent part of the ring-shaped side wall and the ring-shaped step surface is in arc-shaped distribution; the large blades are arranged across the ring-shaped side wall and the ring-shaped step surface; the small blades are arranged on the ring-shaped side wall; the large blades and the small blades are respectively and perpendicularly distributed oppositely to the tangential direction of the ring-shaped side wall; the small blades are in micro-arc distribution from top to bottom; the large blades are distributed on a vertical surface and a micro-arc surface in sequence from top to bottom; the directions of arcs of the large blades and the small blades are consistent to the rotating direction of the impeller.

Description

Centrifugal stirrer

Technical field

The utility model relates to a kind of centrifugal stirrer.

Background technology

What tradition centrifugal stirrer adopted is the impeller of propeller type, and this impeller is inadequate to the stirring dynamics of material, and the area stirring is inadequate.

Summary of the invention

In view of the deficiency of background technology, technical problem to be solved in the utility model is to provide the centrifugal stirrer that a kind of stirring efficiency is higher.

For this reason, the centrifugal stirrer that the utility model provides, comprise driving mechanism and impeller, described impeller comprises blade fixed base, large blade and vanelets, described large blade and vanelets are evenly spaced apart on blade fixed base, blade fixed base comprises annular table terrace and annular sidewall, the curved distribution of annular sidewall and annular table terrace adjacent place, described large blade arranges across annular sidewall and annular table terrace, described vanelets is arranged on annular sidewall, described large blade and vanelets be the tangential vertical distribution of relative annular sidewall all, described vanelets is differential of the arc shape from top to bottom and distributes, described large blade distribute successively from top to bottom vertical plane and differential of the arc face, described large blade and vanelets arc towards direction consistent with the direction of wheel rotation.

In the utility model, large blade and the spaced structure of vanelets on impeller, make the flow trace of impeller current when stirring more complicated, can make to stir the space relating to wider; Large blade and vanelets arc towards direction consistent with the direction of wheel rotation, when impeller stirs, large blade and vanelets can catch current, can strengthen stirring dynamics.Can strengthen mixing effect thus, make stirring efficiency higher.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5, the centrifugal stirrer that the utility model provides, comprise driving mechanism and impeller 1, described impeller 1 comprises blade fixed base 2, large blade 3 and vanelets 4, described large blade 3 and vanelets 4 are evenly spaced apart on blade fixed base 2, blade fixed base 2 comprises annular table terrace 5 and annular sidewall 6, annular sidewall 6 and the 5 curved distributions in adjacent place 7 of annular table terrace, described large blade 3 arranges across annular sidewall 6 and annular table terrace 5, described vanelets 4 is arranged on annular sidewall 6, described large blade 3 and vanelets 4 be the tangential vertical distribution of relative annular sidewall 6 all, described vanelets 4 is differential of the arc shape from top to bottom and distributes, described large blade 3 distribute successively from top to bottom vertical plane 31 and differential of the arc face 32, described large blade 3 and vanelets 4 arcs towards direction consistent with the direction that impeller 1 rotates.In the utility model, large blade 3 and the spaced structure of vanelets 4 on impeller 1, make the flow trace of impeller 1 current when stirring more complicated, can make to stir the space relating to wider; Large blade 3 and vanelets 4 arcs towards direction consistent with the direction that impeller 1 rotates, when impeller 1 stirring, large blade 3 and vanelets 4 can catch current, can strengthen stirring dynamics.Can strengthen mixing effect thus, make stirring efficiency higher.
