Description

I

The invention relates to apparatus for mixing liquid media and can be used in various fields of chemical industry.

The purpose of the invention is to increase productivity.

The drawing shows the proposed reactor, the section (technological fittings conventionally not shown).

The apparatus includes a housing 1, a mixing device 2, consisting of a shaft 3 mounted in bearings 4, and a shaft 5 on which agitator 6 is mounted, a swivel coupling (Guna hinge) 7, connecting shafts 3 and 5, a circulation pipe 8, mounted on a shaft 5 rotatably in bearings 9. with fins 10 on the outer surface of the circulation tube.

The device can work as H periodic, and in continuous mode.

The device works as follows.

The initial products are loaded into the apparatus, where they are mixed with the help of a mixer about the type of meats (screw, screw), depending on the physical properties of the product. Since the shaft of the agitator is made split along its length, when mounting the mixing device, no special centering of the shaft relative to the wupus is required. The agitator is placed in the circulation pipe, which provides intensive axial circulation of the reaction mass in the apparatus, the pumping effect of the agitator depends on its structural para- meters. meters and rotational speeds. The circulation pipe is attached to the shaft of the mixing device by means of bearings, i.e. during operation of the mixing device, the circulation pipe does not rotate. Additionally, to prevent questioner

The ribs 10 are located on the foot of the circulation pipe on its outer surface. At the same time, the circulation pipe provides some

J centering of the mixing device relative to the body both due to its mass and due to its resistance to the precessional motion, which depends on the frontal resistance

FROM the moving large cylinder

The pump effect of the agitator depends on its relative speed relative to the circulation pipe. Therefore, during the operation of the stirrer, the circulation pipe should not have a rotational movement 5, which in the proposed apparatus is achieved by the ribs mounted on the outer surface

:, Q of the circulation pipe and preventing its rotation relative to the reaction mass.

Thus, the proposed technical solution allows for an intensive meridional circulation of the reaction mass in the apparatus and ensures the centering of the mixing device relative to the body without the use of stop stops in the hinge coupling.

In an apparatus with a circulation tube fixed in bearings relative to the shaft of a mixing device, the same conditions of mixing of the reaction mass are achieved as in apparatus with stationary mounted circulation tubes, but at the same time reducing the metal bone of the apparatus, simplifying its manufacture, assembly and service (the latter is especially important when processing rorroznonnyh sDrDz as during preventive maintenance and repair of the casing of the apparatus and the mixing device constant t-ruboy is removed from the device.
