Description

one

The invention of otosite to the field of mineral processing.

A scouring machine is known, comprising chambers, each of which is equipped with a spindle with two impellers.

The proposed device is characterized in that each spindle is made of two shafts — an upper hollow shaft and a lower one-metal one fixed therein. This improves the efficiency of the scrubbing process.

FIG. 1 shows the proposed device; in fig. 2 - split, longitudinal section.

The cleaning machine consists of two chambers of 1 rectangular section, separated by a partition, which has a rectangular window at the bottom. Each camera is equipped with a push rod 2 with two oppositely rotating impellers and a drive 3. The drive can be of a different design depending on the size of the maschine and the number of revolutions of the pinch. On the left, a receiving pocket 4 for pulp is attached to the first chamber, and a discharge pocket 5 is attached to the last chamber.

Wiping machines can be assembled from several double chambers, interconnected in separate sections, like flotation machines.

The presence of a bevel gear provides rotation of the upper hollow 6 and lower all-metal 7 shafts in different directions. At the lower ends of both shafts impellers are reinforced. On the hollow shaft there is installed an impeller 8 and on the all-metal shaft there is a lower impeller 9. The gear shaft can be replaced with any other design that

must ensure that the shafts rotate in different directions. The direction of rotation of the shafts and impellers is shown by arrows (see Fig. 2). The upper impeller 8 rotates clockwise, the pulp downward, and the lower

the impeller 9 rotates counterclockwise, raising the slurry upwards. Such interaction of the scrubbing impellers eliminates pulp unwinding and thus accelerates the scrubbing process with good quality of the product.

The process of rubbing in the mask proceeds as follows.

The pulp is fed into the receiving pocket 4, from which it first enters the first chamber of the maschine, where it is intensively processed. Then the pulp through the lower window in the septum enters the second chamber for re-treatment.

Subject of inventions

A scrubbing machine comprising chambers, each of which is equipped with a spindle with two impellers, is distinguished from that.

that, in order to increase the efficiency of the ftpfl of the scrubbing process, each spindle is made of two shafts - the upper hollow shaft and the lower all-metal one fixed in it.
