The paddle rotates at a high speed under the driving of the stirring shaft to stir reaction liquid, so that the effect of quickly generating crystal particles is achieved. However, when the obtained crystal particles are observed by a high-power electron microscope, a small part of the crystal particles are always cut into smaller particles by a blade rotating at a high speed, and the requirement on the granularity of a crystal product cannot be met.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel open the turbine, the paddle that should open the turbine and relate to can not produce too big radial force when high-speed rotatory to avoid cutting the crystal into the phenomenon of littleer particle, solved and be difficult to satisfy the requirement of crystallization product granularity among the prior art.

In order to achieve the above object, the utility model provides a following technical scheme: novel open turbine, include the paddle of connecting at the (mixing) shaft outer wall along the incline direction, paddle one end fixedly connected with blade base, blade base is the cylinder shape, and blade base's last fixed surface connects in the bottom of (mixing) shaft, the edges and corners department of paddle all sets to the fillet structure, the outer terminal surface of paddle is arc convex surface structure.

Preferably, a connecting plate is welded on the outer wall of the blade base along the inclined direction, and the lower surface of the connecting plate is fixedly connected with the paddle through bolts; in the using process, when the individual blade is damaged, the blade can be conveniently replaced.

Preferably, the edges and corners of the connecting plate are respectively arranged into a fillet structure; the edges and corners of the connecting plate can not cut crystals in the process of high-speed rotation of the connecting plate along with the blade base, and crystal particles with undersize particle sizes are avoided.

Preferably, a stiffened plate is welded at the center of the upper surface of the connecting plate along the axial direction, and one end of the stiffened plate is welded with the outer wall of the blade base; the rigidity and the strength of the connection between the connecting plate and the stirring shaft are improved, and the service life of the whole body is prolonged.

Preferably, the edges and corners of the stiffened plate are respectively arranged into a fillet structure; the edges and corners of the stiffened plate can not cut crystals in the process of high-speed rotation along with the connecting plate, so that crystal particles with undersize grain diameters are avoided.

Preferably, the number of the blades is one of two, three, four, six and eight, and the number of the connecting plates and the reinforcing plates is the same as that of the blades; and selecting the corresponding quantity of the blades according to the stirring requirements of different products.

Preferably, the blades are distributed in an annular array mode by taking the central axis of the blade base as a center; so that the stirring shaft can rotate at high speed more smoothly.

Preferably, the inclination angle of the connecting plate is 45 degrees; so that the blades connected with the connecting plate can be universally applied to most stirring sites.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model relates to a fillet is all carried out to the edges and corners of paddle and is handled, and changes the horizontal terminal surface of paddle into the circular arc convex surface to when making the paddle carry out high-speed rotation under the drive of (mixing) shaft, can not produce too big radial force, thereby eliminated the phenomenon that the crystal integument cut into littleer particle.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the novel starting turbine comprises a blade 2 connected to the outer wall of a stirring shaft in the inclined direction, wherein one end of the blade 2 is fixedly connected with a blade base 1, the blade base 1 is cylindrical, the upper surface of the blade base 1 is fixedly connected to the bottom end of the stirring shaft, the edges and corners of the blade 2 are all arranged in a fillet structure, and the outer end surface of the blade 2 is in an arc convex surface structure; the (mixing) shaft passes through blade base 1 and drives paddle 2 and carry out high-speed rotation, and sharp edges and corners has been eliminated to paddle 2, avoids cutting the knot crystal when high-speed rotation, avoids producing the too little crystal particle of particle diameter to avoid the waste of material.

The outer wall of blade base 1 has connecting plate 3 along the welding of incline direction, the lower surface of connecting plate 3 passes through bolt and 2 fixed connection of paddle, the edge of connecting plate 3 is set to the fillet structure respectively, the central point of connecting plate 3 upper surface puts and has stiffened plate 31 along the axial welding, the one end of stiffened plate 31 and the outer wall welding of blade base 1, the edge of stiffened plate 31 sets to the fillet structure respectively, paddle 2 can be conveniently installed to connecting plate 3 on, simultaneously can demolish from connecting plate 3 conveniently again, thereby make the stirring in-process, when individual paddle 2 damages, can conveniently swiftly change damage paddle 2, setting through stiffened plate 31, make holistic rigidity and intensity improve.
