Description

Cup-like stirrer

Technical field

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

Background technology

Because whipping process is of a great variety, the medium situation varies at present, so the agitator pattern of using is varied, slurry formula, open turbine formula, disc turbine formula, push type, anchor formula, frame, helical-ribbon type etc. is arranged typically.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-like stirrer, it is applicable to the slow-speed of revolution and stirs.

For realizing the cup-like stirrer of described purpose, be characterized in, it is the bend pipe of a circular arc, have large end face and small end face, the cup-like stirrer of take is placed on a situation on baseplane and is reference, it has centre of gyration line, from centre of gyration line O, set 90 degree sector regions, this 90 degree sector region is by first reference planes of radially extending, second reference planes of radially extending limit, first, the second reference planes become 90 degree angles, from the direction perpendicular to baseplane, cup-like stirrer is arranged in this sector region, cup-like stirrer and the first reference planes have the first intersection point, the vertical curve perpendicular to baseplane at the first intersection point place of take is benchmark, after rotating the first reference planes predetermined angular in sector region, in the reference planes of the small end face of cup-like stirrer after deflection, cup-like stirrer has axially extended median plane, it is perpendicular to baseplane, median plane and the second reference planes have the first intersection, from the first intersection, extend the 4th reference planes that are parallel to the first reference planes, and intersect from median plane and the first reference planes the 5th reference planes that set positions that part departs from preset distance is parallel to the second reference planes, the 3rd crossing intersection of the 4th reference planes and the 5th reference planes of take is benchmark, rotate the 4th reference planes predetermined angular, thereby determine the 6th reference planes, the intersecting lens of the 6th reference planes and baseplane of take again is benchmark, to small end face direction deflection the 6th reference planes predetermined angular, the large end face of cup-like stirrer is just in the 6th reference planes after deflection, each reference planes are all perpendicular to described baseplane.

Aforementioned cup-like stirrer can a plurality ofly uniformly-spaced arrange along a circumference, and small end face is upward down for large end face.Be applicable to the slow-speed of revolution, during stirring, do not bring air into, shearing force is extremely low, can be used for the viscosity of 3.5 ten thousand cp, economizes 1/3 power than common stirring; But place at center and eccentric the placement, from closer at the bottom of still.Stream shape is for stirring 2 systemic circulations in top, 2 of belows partial circulating.

The accompanying drawing explanation

Fig. 1 is the front view of cup-like stirrer.

Fig. 2 is the right view of cup-like stirrer.

Fig. 3 is the schematic diagram of cup-shaped agitating device.

The specific embodiment

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

Continue to see figures.1.and.2, cup-like stirrer has axial median plane L3(perpendicular to baseplane), median plane L3 and reference planes L2 have intersection P2, from intersection P2, extend a reference planes L4 who is parallel to reference planes L1, and from median plane L3 and reference planes L1, intersect part and depart from preset distance D1(and be greater than caliber, the set positions that is about 38mm is parallel to the reference planes L5 of reference planes L2, reference planes L4 and reference planes L5 intersecting lens P3 are benchmark, rotate for example 12 degree of reference planes L4 predetermined angular A2() determine reference planes L6, the intersecting lens of reference planes L6 and baseplane of take again is benchmark, to small end face 100 direction deflection reference plane L6 predetermined angulars, for example 10.5 spend, the large end face 200 of cup-like stirrer is just in the reference planes L6 after deflection, large end face is 5mm to the maximum in baseplane Shang De projection width.

As shown in Figure 3, rotating shaft 11 is connected with three cup-like stirrers 10 by connecting rod 110, form agitating device, three cup-like stirrer 10 interval 120 degree, and hold greatly 200 down, small end 100 is upward, during stirring, do not bring air into, shearing force is extremely low, can be used for the viscosity of 3.5 ten thousand cp, economizes 1/3 power than common stirring; But place at center and eccentric the placement, from closer at the bottom of still.Stream shape is for stirring 2 systemic circulations in top, 2 of belows partial circulating.
