Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The schematic diagram that is applied in the shaft in reactor that accompanying drawing 1 provides for the utility model preferred embodiment;
Wherein: 1, rotating shaft; 2, paddle assembly; 3, sleeve; 4, stirring vane; 5, through hole; 6, groove; 7, connector; 71, bolt; 72, nut; 8, groove.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, in the present embodiment, be applied in the shaft in reactor, comprise a rotating shaft 1 and many group paddle assemblies 2, wherein said paddle assembly 2 is fixed in rotating shaft 1 successively along the axial direction of rotating shaft 1; Wherein said many group paddle assemblies 2 all adopt Modular Structure Design, and each paddle assembly 2 particularly, can be divided into again a sleeve 3 and the annular array a plurality of stirring vanes 4 on sleeve 3 sidewalls.In order to improve this shaft its stirring efficiency that can play in use, can stirring vane 4 structures in every group of paddle assembly 2 be arranged to different.
According to currently available technology, to being applied in the understanding of stirring vane in the shaft in reactor, the stirring vane 4 in the present embodiment can be set to the stirring vane of oar formula stirring vane, anchor formula stirring vane, rotary propeller type stirring vane and helical-ribbon type stirring vane or other structural formula.Because the paddle assembly 2 in the present embodiment is to adopt modular structural design, this shaft is when concrete use like this, can rotate according to the character of the required material stirring the stirring vane of different structure form, and the number of the required stirring vane using, to promote the demand of material mix and blend effect in all directions, so just can accelerate the reaction rate of storeroom.And then, improved product quality and production efficiency.Simultaneously because the paddle assembly 2 for stirring is the settings of dismountable modularization, like this in the process that this shaft is being used, when this is damaged for the stirring vane stirring, only need to change paddle assembly 2, saved the production cost of enterprise.
