Description

telnm pole of the current source, and PB 1 and 6 - with a negative pole. The pulp from the loading device is continuously fed between rotating PB 1 and 6.

The invention relates to the enrichment of minerals, mainly for the separation of suspensions into component phases, and can be used in mechanical engineering, chemical building and other industries.

The purpose of the invention is to increase the productivity and quality of the separation of solid particles through directional filtration.

FIG. 1 shows the device section; in fig. 2 - connecting the poles to the current source.

The device for separating solid particles from the suspension contains an inclined mounted perforated drum 1, made in the form of a hollow truncated cone supported on bearings 2. The forming drum, passing through its lower point, is inclined to the horizon at an angle O- 15 °. The smaller base of the drum and the slope of its generators are turned towards the discharge of the solid phase. Drum | l is driven by a drive. A sub-don 3 is installed for receiving the liquid, a receiver 4 for the solid phase, and a tray 5 for feeding the pulp into the drum. The drum 1 is equipped with an additional perforated drum 6 mounted coaxially with the drum 2 and rigidly connected to it. The opposite surfaces of the main 1 and additional 6 drums are covered with a capillary-porous material 7 and a cylindrical electrode 8 is mounted between them, rigidly connected to the drum 1 and connected to the positive pole of the current source 9. The main 1 and additional 6 drums are connected to the negative by the pole of the current source 9. The drums 1 and 2 by the isolis of the current source create the effect of electroosmosis, under the action of which the liquid phase moves through PBM 7 to PB 1 and 6. The liquid is filtered through perforation. The solids move along the length of PB 1 and 6 in the direction of their smallest diameter. 2 Il.

from the cylindrical electrode 8.

The device works as follows.

The pulp tray 5 is continuously supplied between the rotating main drum 1 and the additional drum 6. The liquid phase is in contact with the capillary-porous material 7 due to

the action of capillary forces impregnates it and comes into contact with the main perforated drum 1 and an additional 6. The presence of a cylindrical1 o electrode B, associated with a positive

by the source of power supply 9, creates the effect of electroosmosis, under the action of which the liquid phase through the capillary-porous material 7 moves to the drums 1 and 6. Through the perforation

the liquid is filtered and flows into the tray 3, and the solid particles under the influence of friction on the surface of the material 7 are carried upwards in the direction of rotation of the drums and under the action of force

The body falls, moving along the length of the drum by the amount b in the direction of the smallest diameter. Discharge solids are received by receiver 4.

Due to repeated drops of their capillary particles, the moisture is mechanically destroyed by the capillary forces of the material 7 and the external electric field through a perforation

the drums flow into the tray 3, and the degree of dehydration of the particles increases. With a drum diameter of 800 Io 200 mm, a rotational speed of 60 min,: tilt angle 15% performance

devices will be 15-20 t / h.
