Abstract
The invention discloses a rotary low-shear static mixer, relates to a static mixer and in particular relates to a rotary low-shear static mixer. The invention aims to solve the problem that the conventional static mixer is high in viscosity loss and non-ideal in uniform mixing effect. The rotary low-shear static mixer comprises a tube shell, a spindle, two shaft seats, a plurality of driving blades and a plurality of stirring units, wherein the spindle is arranged in the tube shell; the shaft seats are respectively arranged in two ends of the tube shell; two ends of the spindle are respectively arranged on the corresponding shaft seats; the plurality of driving blades are sleeved on the driving blade sections on the spindle at equal intervals; and the plurality of stirring units are sleeved on stirring unit sections on the spindle at equal intervals. The rotary low-shear static mixer is used for mixing and diluting polymer mother solution and water.
Description
Technical field
The present invention relates to a kind of static mixer, be specifically related to a kind of rotary-type low shearing static mixer.
Background technology
Polymer mother liquor and water mixed diluting stage must have viscosity loss, and from analyzing data, this stage, sticking loss rate was bigger.Mainly be that polymer mother liquor and the aqueous solution are constantly cut apart, turned to, and produce self mixing effect, by convection current, shearing, dispersion, distribution effect, reach preliminary mixing in the cutting apart under the cyclonic action of existing static mixer mixed cell.Just because of this, conventional static mixture causes the high molecular degraded of polymer, and molecular characterization changes, and causes viscosity to descend, and viscosity loss is up to 8%.And if the degree of cutting apart is sheared in control, can influence the uniformity coefficient that mixes the back polymer again, make it become a pair of contradiction.Existing static mixer is generally controlled the degree of irregularity after the mixed with polymers about 5%, and the not ideal enough also real genus of mix uniformly effect is helpless.Though other have some compound type static mixers comparatively speaking effect promote to some extent, do not solve this in essence to the contradiction between the mixed with polymers uniformity and viscosity loss.
Summary of the invention
The present invention is the big and bad problem of mix uniformly effect for the existing static mixer viscosity loss of solution, and then proposes a kind of rotary-type low shearing static mixer.
The present invention addresses the above problem the technical scheme of taking to be: the present invention includes shell, main shaft, two axle beds, a plurality of driven vane and a plurality of agitating units, main shaft is arranged in the shell, shell respectively is provided with an axle bed respectively in two ends, the two ends of main shaft respectively are installed in respectively on the corresponding axle bed, a plurality of driven vane equidistantly are sleeved on the driven vane section on the main shaft, and a plurality of agitating units equidistantly are sleeved on the agitating unit section on the main shaft.
The invention has the beneficial effects as follows: compare with conventional static mixer, the present invention has abandoned conventional hybrid unit such as SV type, SX type, SK type, SD type, and the mode that adopts driven vane to drive the agitating unit rotation realizes that liquid mixes; Cylinder transition on the agitating unit is smooth, do not have sharp corner angle, can reduce the shearing force that conventional static mixer causes thus, can reduce the viscosity loss of polymer.
Description of drawings
Fig. 1 is front view of the present invention, and Fig. 2 is the left view of Fig. 1.
