Further, the blade unit comprises two guide surfaces, which respectively correspond to two adjacent blade units of the blade unit.
Further, the blade monomer includes first connecting portion, second connecting portion and two circular arc portions, and first connecting portion are T style of calligraphy body coupling with the second connecting portion, and two circular arc portions are integrative respectively to be set up in two contained angle departments of first connecting portion and second connecting portion, form two spigot surfaces in second connecting portion both sides.
Further, a gap for the material to pass through is formed between the first connecting parts of the two adjacent blade monomers.
Further, the stirrer for producing rosuvastatin further comprises a bottom paddle arranged at the end part of the transmission shaft, and when the transmission shaft drives the bottom paddle to rotate, the bottom paddle can drive the material to move towards the bottom paddle.
Compared with the prior art, this a stirring vane for producing agitator of rosuvastatin includes a plurality of blade monomers of arranging along the transmission shaft axial, two adjacent blade monomers have reverse spigot surface, when the stirring, the material flows along with the spigot surface, from the free spigot surface flow direction of a blade to the free spigot surface of another adjacent blade, the material that highly flows directly erodees the spigot surface, wash away the crystallization of above-mentioned, realize the function of automatically cleaning, effectively avoided stirring vane surface crystallization to lead to the problem that must regularly clear up.
Drawings
Fig. 1 is a schematic structural diagram of a stirrer for producing rosuvastatin provided by the present invention;
fig. 2 is a cross-sectional view of the blade unit of fig. 1.
Detailed Description
The following detailed description of the preferred embodiments of the invention, which is to be read in connection with the accompanying drawings, forms a part of this application, and together with the embodiments of the invention, serve to explain the principles of the invention and not to limit its scope.
Referring to fig. 1 and 2, the stirrer for producing rosuvastatin includes a driving shaft 1, a stirring blade 2 and a bottom blade 3. This agitator is arranged in stirred mixture reation kettle 4's material in reation kettle 4, is formed with a cauldron chamber in reation kettle 4, still is provided with the feeding and discharging device in intercommunication cauldron chamber on reation kettle 4, and feeding and discharging device can be inlet pipe and discharging pipe, also can be feed inlet or discharge gate etc.. This agitator is placed in the cauldron intracavity, and 1 one end of transmission shaft extends out from the cauldron intracavity, connects outside power supply, like the motor, under the drive of power supply, the agitator is at cauldron intracavity internal rotation, the material of mixing kettle intracavity.
External power source is connected to 1 upper end of transmission shaft, and the lower extreme extends to the bottom in cauldron cavity and connects bottom paddle 3, and one section distance in bottom paddle 3 distance reation kettle 4's lower bottom surface drives when rotatory at transmission shaft 1, can drive the crystallization orientation of reation kettle 4 bottom and pass the motion of bottom paddle 3, avoids the crystallization deposit in reation kettle 4's bottom.
One set or multiunit stirring vane 2 sets up on the side of transmission shaft 1, for the stirring more even, stirring vane 2 encircles 1 evenly distributed of transmission shaft, and stirring vane 2 width and reation kettle 4's internal diameter size suit everywhere for stirring vane's 2 end keeps certain distance apart from reation kettle 4's inner wall, keeps 5 centimetres of clearance in this embodiment, and stirring vane 2 can scrape the crystallization on reation kettle 4 inner wall when rotatory along with transmission shaft 1 like this.
Stirring vane 2 includes a plurality of blade monomers 21 of arranging along 1 axial direction of transmission shaft, and blade monomer 21 has at least one spigot surface, and blade monomer 21 staggered arrangement forms stirring vane 2 for the spigot surface of two adjacent blade monomers 21 is along the opposite direction of 1 circumference orientation of transmission shaft, and the spigot surface of two adjacent blade monomers 21 is along 1 circumference direction coincidence of transmission shaft. When transmission shaft 1 drives stirring vane 2 rotatory like this, the material can flow along with the spigot surface to wash the spigot surface, clean the crystallization on the spigot surface.
In this embodiment, the single blade 21 includes a first connecting portion 211, a second connecting portion 212 and two arc portions 213, the first connecting portion 211 and the second connecting portion 212 are integrally connected in a T shape, and the two arc portions 213 are respectively integrally disposed at two included angles between the first connecting portion 211 and the second connecting portion 212, so as to form two guide surfaces on two sides of the second connecting portion 212. The two guide surfaces respectively correspond to two adjacent blade single bodies 21, and a gap for passing the material is formed between the first connecting parts 211 of the two adjacent blade single bodies 21. Like this when rotatory, the material passes the clearance along with the spigot surface motion and moves to the spigot surface of two adjacent blade monomers 21 again, can wash out the crystallization on two spigot surfaces that two adjacent blade monomers 21 are relative clean at this in-process to realize the function of automatically cleaning, effectively avoided the adhesion of crystallization on the spigot surface, avoided artifical clean.
In the use, thereby can also change the direction of rotation of transmission shaft 1 and change the direction of stirring for the material washes the guide surface from two directions in turn, thereby obtains more thorough clean effect.
Implement the embodiment of the utility model provides a, following beneficial effect has: this a stirring vane for producing agitator of rosuvastatin includes a plurality of blade monomers of arranging along the transmission shaft axial, two adjacent blade monomers have reverse spigot surface, when the stirring, the material flows along with the spigot surface, from the free spigot surface flow direction of a blade to the free spigot surface of another adjacent blade, the material that highly flows directly erodees the spigot surface, wash away the crystallization of higher authority, realize the function of automatically cleaning, effectively avoided stirring vane surface crystallization to lead to the problem that must regularly clear up.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
