Description

one

This invention relates to chemical machinery.

Known mixers with a mixing device, comprising a horizontal housing, an actuator, a shaft with a seal and a paddle stirrer made of half pipes.

The purpose of the invention is to intensify the mixing process.

The proposed mixer is characterized in that the half-tubes of the agitator are closed at the ends, are installed parallel to the axis of the shaft and are turned with the concave side in the direction of rotation. Optimally, the longitudinal edges of the half-tubes are jagged.

FIG. 1 shows the proposed mixer with a paddle stirrer; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. one.

The mixer comprises a horizontal housing /, covers 2, a shaft 3 of the agitator, a drive shaft 4 and a paddle stirrer consisting of hubs 5, ribs 6, loiastes 7. The blade is made of a pipe that is plugged at both ends and is welded to the ribs. In the interval between the ribs on the pipe, cuts are made in such a way that the blade in cross section has the shape of a half pipe. The voguta surface of the lobe, STI is installed parallel to the axis of the hubs and faces in the direction of rotation, and the edge of the center of the half pipe has a jagged shape.

Mixed with a cable with a mixer; and the device works in the following way.

In Corus iodine and iodine blending, liquid and gas are used in such a way that the filling ratio of the mixer with liquid is less than one unit and there is a gas space above the level.

By means of the shaft 3 of the agitator and the drive shaft 4 the agitator is built. The rim passes through the gas cavity and the liquid zone. Each area is directed by a concave surface, which is aerated to the mirror of the liquid, and consequently, at the moment of incursion onto the liquid, the cavity formed by the half-pipe wall and the cut line is filled with gas. By mixing the loop and the liquid phase, the gas from the cavity is replaced due to the difference in density but Bceii the length of the loop and enters the liquid. The size of the gas bubbles is determined by the size and shape of the cut edge of the iolutrub. The shaped shape of the iolutrub edge provides a raviomeric distribution of the liquid phase, trapped in a semi-tube, into trickles in the gas cavity of the mixer. In such a mixer, the amount of gas entering the liquid is determined by multiplying the frequency of rotation by the amount of pipe and the volume of the iolith and pipe. From this it follows that the volume of gas iodized into the liquid can be increased and the increase in the amount of liquid in their volume without increasing the frequency of the vradenden.

Subject invention

1. A gas-liquid mixer for treating a system containing a horizontal body, an irivod, a shaft with a seal on a paddle stirrer, made of half pipes, characterized in that, in order to intensify the mixing process, the pipe is closed at the ends, parallel to the shaft axis and turned concave side in the direction of rotation.

2. Mixer io and. 1, characterized in that the irodol edges of the nolutrub are serrated.
