Description

2. The device according to p. I, about tl and - so that the working surfaces of the disks and cone-shaped

The invention relates to construction equipment, in particular, to installations for the activation of cement-sand mortars,

The aim of the invention is to increase the degree of activation of cement pastes and cement-sand mortars by eliminating transit flow (stagnant zones of the material), increasing the path of the processed material during intensive shear and abrasive deformations and increasing the cavitation effects in the processed material.

Fig. 1 schematically shows a device for activating a cement-sand mortar; in fig. 2 is a section A-A in FIG. 1,

The device consists of vibro-capacitance 1, mounted on shock absorbers 2 of receiving 3 and output 4 of leakage, electric drive 5, driving shaft 6, on which disks 7 are fixed, having a cutout on the edge and a vertically mounted knife 8, with a cutout in each subsequent disc offset 180 ° from the upstream, in the body of the disk from the side of the working surface in chess order in the direction from the periphery to the center at an angle of 30-75 are made depressions 9, Electric drive 5 and vertical shaft 6 with disks 7 are mounted on frame 10, which ra attached to the base of the foundation. Cone-shaped guides 11 are fixed on the inner surface of the container 1, The upper working surfaces of the disks 7 and the cone-shaped guides have a layer I2 of abrasive material.

guides are coated with an abrasive material.

The device works as follows.

The electric drive 5 is turned on. Through the leakage 4, a solution is supplied which, under the action of its own mass, enters the rotating disk 7 of vibration capacity I. Under the action of centrifugal forces, the treated solution undergoes shear and abrasive deformations, rotates and spreads in a thin layer along the surface of the disk, and then hitting the vibrating surface of the container 1 loses speed. Under the dei

By the action of vibration and its own mass, the material being processed falls from the walls of the container 1 and falls through the cone-shaped guide 11 onto the downstream rotating disk 7, where it continues to be further cavitated and abraded, and then removed from the walls with a vertical knife 8 and falls through the cutout at the periphery of the disk 7 to guide I1, which continues to move from the angular and vibrational velocity to the center of the lower disk,

Similarly, the treated solution is moved to the third, fourth, and other disks. The number of rotating discs and tapered guides depends on the optimal number of activation repeats for a particular type of solution.

Through the outlet chute A, the activated solution is removed from the device by the action of its own mass and vibration.
