Description

2. The device according to claim 1, about tl and.that the ribs are set at an angle of 20-60 to the plane of the cross section of the agitator and are directed in opposite directions relative to the axis of the shaft.

3. The device according to claim 1, about tl and the fact that the angle of the invention relates to mixing devices, in particular to devices for preparing solutions of flocculants, and can be used in mining, chemical petroleum, metallurgical and other industries. industry.

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

Fig. 1 shows a device, a general view, a section J in Fig. 2, a section A-A in Fig. 1 in Fig. 3, an attachment point for gutter-shaped blades.

Mixing device consists of a vertical tank 1, boot 2 and discharge 3 nozzles, screws 4 with turns of opposite directions, mounted on the shaft 5 connected to the drive 6, agitator 7 and baffles 8.

A stirrer 7 mounted between the screws is mounted on a shaft 5 in common with the auger in the tank 1 and consists of double horizontal bars 9, between which at an angle of 20-60 (preferably 45) there are fixed ribs 10 symmetrically relative to the transverse axis of the mixer 7 and directed in opposite directions ( Fig. 2) The distance between the strips 9 is 30-60 mm (preferably 35 mm), their width is taken from the strength conditions. The slats 9 of the agitators are provided with groove-shaped blades 11 with the possibility of their rotation in the horizontal plane, made in the form of a half hollow cylinder (Fig. 1) with the open side 1 facing out. Each blade 11 (Fig. 3) is equipped with paired half disks 13 with fixed coaxial holes 14. Doloudis 13 on the axis 15 are fixed with a hinge of grooved blades of not more than 90.

4. The device according to A.1, st tl and - in that it is provided with reflective partitions, made with rectangular cuts and installed with the possibility of rotation,

but on the bars 9, forming a hinge, whereby the blade 11 can turn around the axis 15 at angles from 0 to 90 (preferably 45) relative to the axis of the shaft and fixed i fixedly through the holes 14 by the clips 16.

The reflective partitions 8 are made in the form of flaps 17 with a right

coal cuts and installed with the possibility of rotation on the vertical axis x 18 (figures 1 and 2). The flaps have on the outside at full height through alternating notches 19

and protrusions 20. The baffles 8 are evenly spaced around the inner perimeter of the vertical tank 1. Their dimensions and the turning angle depend on the volume of the tank, its

parameters and properties of flocculation solutions obtained. The container has a loading opening 21 and a scraper 22. In Fig. 3, the thin line shows the position of the rotated blade.

The device works as follows.

The vertical tank 1 is filled with water through the nozzle 2 to a predetermined level, the flaps 18 of the reflective

The partitions are installed at a certain angle, the actuator 6 is turned on. Then a flocculant is fed into the container 1 through the upper filling opening 21. The finished solution is removed from

device through pipe 3.

(I

The presence of screws 4 with different directions of turns creates multidirectional movements of the streams: in the lower part of the tank from the bottom up, along with clots of flocta nta, lifted by the scraper 22, in the upper part from the top: down. Stirred agitator on shaft 5

7 enhances the separation of flows, prevents sticking of gel-like flocculant on spirals and contributes to the creation of additional flows in the volume of the mixed liquid.

The creation of additional turbulent flows also contributes to the presence of ribs 10 between the slats 9 of the agitator and reflective walls 8 along the walls of the vertical tank 1.
