Abstract

A high-shear mixing reaction kettle is characterized in that a guide cylinder (9) is arranged at the periphery in a reaction cylinder body (3); fixing plates are mounted between the guide cylinder (9)and a stirring shaft (2) and are sleeved outside a polytetrafluoroethylene ring (7); each fixing plate is provided with fixing pieces distributed at the periphery of the polytetrafluoroethylene ring(7); the polytetrafluoroethylene ring (7) is sleeved at the periphery of the stirring shaft (2); shear blades (4) are mounted above each fixing plate and are fixedly mounted at the periphery of the stirring shaft (2); and paddles of a stirrer (6) are near an inlet at the lower part of the guide cylinder (9). Another polytetrafluoroethylene ring (7) is also arranged in the center of the bottom partof the reaction cylinder body (3); the stirring shaft (2) extends to the center of the bottom part of the reaction cylinder body (3) and is sleeved on the polytetrafluoroethylene ring (7); a bearing(1) is arranged at the upper part of the stirring shaft (2); and another bearing (1) is also arranged at the joint of the stirring shaft (2) and the cover of the reaction cylinder body (3). The utility model has the function of shearing, can improve the dissolution rate of rubber and other polymer materials, and has the advantages of firm fixation.

Description

High-shear mixing reaction kettle

Technical field

The invention relates to reactor, is specifically related to high-shear mixing reaction kettle, belongs to chemical machinery field.

Background technology

The stirring of tradition reactor is anchor formula or paddle formula mostly, mixing very inapplicable to macromolecular materials such as natural rubber or synthetic rubber, because they can only rely on solvent to dissolve, often dissolution velocity is very slow.

Summary of the invention

The invention technical problem to be solved is: at the above-mentioned shortcoming that traditional reactor stirs, provide a kind of have shear high-shear mixing reaction kettle function, that can improve macromolecular material dissolution velocity such as rubber.

The technical solution of the invention: high-shear mixing reaction kettle, comprise reacting cylinder body, agitator, having around reacting cylinder body is outer has agitator to be contained on the shaft in heat transfer jacket, the reacting cylinder body, it is characterized in that, around in reacting cylinder body a guide shell is arranged, one or more fixed disks are housed between guide shell and the shaft, fixed disk is enclosed within outside the ptfe ring, three or three above stators are arranged on each fixed disk, be distributed in around the ptfe ring; Ptfe ring be enclosed within shaft outer around; Two or two above shear-blades are housed above each fixed disk, shear-blade be fixedly mounted on shaft outer around; Agitator is contained in the shaft bottom near the reacting cylinder body bottom centre position, and the blade of agitator is near import below the guide shell; In reacting cylinder body bottom centre a ptfe ring is arranged also, shaft is deep into reacting cylinder body bottom centre, is enclosed within on the ptfe ring; A bearing is arranged on shaft top, and also there is a bearing junction of shaft and reacting cylinder body lid.

Shear-blade has been arranged, utilized the cutting force between blade and the stator, can shred macromolecular materials such as natural rubber or synthetic rubber, improved dissolution velocity.

Utilize the blade of bottom agitator that material is entered in the guide shell around the reacting cylinder body bottom, return the reactor top, make it repeatedly enter cutting system and cut dispersion, promote dissolving.

Because cutting system system moment of torsion is very big, so a bearing is housed on shaft top, a bearing also is equipped with in the junction of shaft and reacting cylinder body lid, and shaft is deep into reacting cylinder body bottom centre, be enclosed within on the ptfe ring, improved the stability of shaft.

The invention has the dissolution velocity of shearing function, improving macromolecular materials such as rubber, and fixation.

The specific embodiment

A kind of embodiment of the invention is described in conjunction with the accompanying drawings.

High-shear mixing reaction kettle, comprise reacting cylinder body 3, agitator 6, having around outside the reacting cylinder body 3 has agitator 6 to be contained on the shaft 2 in heat transfer jacket 8, the reacting cylinder body 3, it is characterized in that, around in reacting cylinder body 3 guide shell 9 is arranged, two fixed disks are housed between guide shell 9 and the shaft 2, fixed disk is enclosed within outside the ptfe ring 7, eight stators 5 are arranged on each fixed disk, be evenly distributed on around the ptfe ring 7; Around ptfe ring 7 is enclosed within outside the shaft 2; Three shear-blades 4 are housed, around shear-blade 4 is fixedly mounted on outside the shaft 2 above each fixed disk; Agitator 6 is contained in shaft 2 bottoms near reacting cylinder body 3 bottom centre positions, and the blade of agitator 6 is near import below the guide shell 9; In reacting cylinder body 3 bottom centre a ptfe ring 7 is arranged also, shaft 2 is deep into reacting cylinder body 3 bottom centre, is enclosed within on the ptfe ring 7; On shaft 2 tops a bearing 1 is arranged, shaft 2 also has a bearing 1 with the junction of reacting cylinder body 3 lids.
