Description

Cup-shaped agitator

Technical field

The mixing plant that the present invention relates to a kind of homogeneous mixture of material and quicken heat transfer and mass transport process

Background technology

Because whipping process is of a great variety, and the medium situation varies, so the agitator pattern of using is varied, the slurry formula is arranged typically, open turbine type, disc turbine formula, push type, anchor formula, frame, helical-ribbon type etc. at present.Every kind of agitator pattern has its advantage, but certain limitation is also arranged.

Summary of the invention

The object of the present invention is to provide a kind of cup-shaped agitator, it is applicable to slow-speed of revolution stirring.

For realizing the cup-shaped agitator of said purpose, be characterized in, be the bend pipe of a circular arc; Have large end face and small end face, being placed on a situation on the baseplane with cup-shaped agitator is reference, and it has centre of gyration line; Set 90 degree sector regions from centre of gyration line O, this 90 degree sector region is limited by second reference planes of first reference planes of radially extending and radially extension; First, second reference planes become 90 degree angles, see that from the direction perpendicular to the baseplane cup-shaped agitator is arranged in this sector region; The cup-shaped agitator and first reference planes have first intersection point; The vertical curve perpendicular to the baseplane with first intersection point place is a benchmark, in sector region, rotate the first reference planes predetermined angular after, in the reference planes of the small end face of cup-shaped agitator after deflection; Cup-shaped agitator has axially extended median plane; It is perpendicular to the baseplane; The median plane and second reference planes have first intersection, from first intersection extend one be parallel to first reference planes the 4th reference planes, and intersect the Wucan that set positions that part departs from preset distance is parallel to second reference planes from median plane and first reference planes and examine the plane; The 3rd intersection of examining Plane intersects with the 4th reference planes and Wucan is a benchmark; Rotate the 4th reference planes predetermined angular, thereby confirm the 6th reference planes, the intersecting lens with the 6th reference planes and baseplane is a benchmark again; To small end face direction deflection the 6th reference planes predetermined angular, the large end face of cup-shaped agitator is just in second reference planes after deflection; Each reference planes is all perpendicular to said baseplane.

Aforementioned cup-shaped agitator can uniformly-spaced arrange by a plurality of edges one circumference, and small end face is up down for large end face.Be applicable to the slow-speed of revolution, do not bring air during stirring into, shearing force is extremely low, can be used for the viscosity of 3.5 ten thousand cp, economizes 1/3 merit than common stirring; But the center is placed with eccentric and placed, and is closer at the bottom of still.Stream shape is for stirring 2 systemic circulations in top, 2 partial circulatings in below.

The specific embodiment

As depicted in figs. 1 and 2, in Fig. 1, cup-shaped agitator is placed on the baseplane, and cup-shaped agitator is cylinder-shaped, cup-shaped agitator be a caliber be about 27mm 90 the degree elbows the basis on form, it has centre of gyration line O.For the ease of description, set 90 degree sector regions from center line O, this 90 degree sector region is limited by the reference planes L2 of reference planes L1 that radially extends and radially extension, and two plane L1, L2 become 90 degree angles.See that from direction cup-shaped agitator is arranged in this sector region perpendicular to the baseplane.Cup-shaped agitator and reference planes L1 have intersection point P1, are benchmark with intersection point P1 place vertical curve, in sector region, rotate reference planes L1 predetermined angular after, for example behind 8 degree, in the reference planes L1 of small end face 100 after deflection of cup-shaped agitator.

Continue to see figures.1.and.2, cup-shaped agitator has axial median plane L3 (perpendicular to the baseplane), and median plane L3 and reference planes L2 have intersection P2; From intersection P2 extend one be parallel to reference planes L1 reference planes L4; And intersect part from median plane L3 and reference planes L1 and depart from preset distance D1 (greater than caliber, the set positions that is about 38mm is parallel to the reference planes L5 of reference planes L2, and reference planes L4 and reference planes L5 intersecting lens P3 are benchmark; Rotate reference planes L4 predetermined angular A2 (for example 12 degree) and confirm reference planes L6; Intersecting lens with reference planes L6 and baseplane is a benchmark again, and to small end face 100 direction deflection reference planes L6 predetermined angulars, for example 10.5 spend; Just among the reference planes L6 after deflection, the projection width of large end face on the baseplane is 5mm to the maximum to the large end face 200 of cup-shaped agitator.

As shown in Figure 3, rotating shaft 11 is connected with three cup-shaped agitators 10 through connecting rod 110, constitutes agitating device; Three cup-shaped agitator 10 intervals 120 degree, and hold 200 greatly down, lower end 100 is up; Do not bring air during stirring into; Shearing force is extremely low, can be used for the viscosity of 3.5 ten thousand cp, economizes 1/3 merit than common stirring; But the center is placed with eccentric and placed, and is closer at the bottom of still.Stream shape is for stirring 2 systemic circulations in top, 2 partial circulatings in below.
