The specific embodiment

Like Fig. 1 and shown in Figure 2: a kind of numerical control on-line continuous blender; Comprise vertical tank body 1, motor 5 and agitating device; Horizontal direction is provided with three annular diaphragm plates 4 in the vertical tank body 1, and annular diaphragm plate 4 is divided into four layers of relatively independent stirring layer 101 with vertical tank body 1, and annular diaphragm plate 4 centers are provided with through hole 401; Six curving grooves 402 are offered at through hole 401 edges; Agitating device comprises shaft 2 and is installed on 3, one agitators 3 of four agitators on the shaft 2 and be positioned at one deck and stir layer 101 that motor 5 is numerical control variable-frequency motors.

Referring to Fig. 3 and Fig. 4: annular diaphragm plate 4 evenly is provided with sieve aperture 403; In order to guarantee the load performance of vertical tank body 1, ellipse head is established in vertical tank body 1 bottom, and oval capping 6 is installed on vertical tank body 1 top.

Eccentric and bend in whipping process in order to prevent shaft 2, referring to Fig. 1, vertical tank body 1 bottom is welded with support 7, and shaft 2 lower ends are installed on the support 7 by bearing; Referring to Fig. 5 and Fig. 6, orlop agitator 301 is that oblique leaf is opened turbotype structure, and six of the numbers of blade produce radial and axial mixed flow in whipping process, and propelling fluid flows from bottom to top when mixing; Referring to Fig. 7 and Fig. 8; Intermediate layer agitator 302 is a palintrope leaf disc turbotype structure; Central authorities' disk stops fluid directly to flow through blender, avoids producing local incomplete mixing phenomenon, and it is little that the palintrope impeller structure stirs resistance; Increase the adaptability of fluid flow ability and fluid viscosity, the rapid Continuous that also can be used for the medium-viscosity material is mixed; Referring to Fig. 9 and Figure 10, the superiors' agitator 303 is that straight leaf is opened turbotype structure, has to shear and mixed, guarantees the even mixing of fluid both macro and micro.
