Description

(54) DEVICE FOR ATTRACTION

The invention relates to devices for the destruction of technological and other types of foam before it is supplied to dewatering devices, such as vacuum filters or thickeners, and can be used in mineral processing. A known installation for defoaming, including a vortex device made in the form of impellers rotating on a vertical shaft, a differential valve, a central nozzle 1. The closest in technical essence and the achieved result to the proposed is a device for defoaming, including a housing with an inlet nozzle and a differential valve , a vertical shaft with disks, on the upper surface of which radial vanes 2 are placed. A disadvantage of this device is the low foam destruction efficiency, containing a large amount of fine mineral components that are easily soaked in water, for example, coal beds or northern ore; practical difficulty in stabilizing the level of pulp in the working space of the apparatus. The purpose of the invention is to intensify the defoaming process. The goal is achieved by the fact that the device is provided with a cylindrical-conical mesh insert fixed to the body and with additional radial vanes placed on the underside of the disks, the blades being perforated. The inlet is set tangentially. FIG. I schematically shows an antifoaming device; in fig. 2 - blade disc, general view; in fig. 3 - the same, top view. The device includes a housing 1, an inlet 2, an outlet 3 for pulp removal, a cylindrical-conical mesh insert 4, a vertical shaft 5, discs 6, perforated vanes 7, a drive jaw 8, an electric motor 9 supporting the partition 10, a differential valve 11. The device works as follows in a way.

Thus, due to the stability of the inertial forces, the presence of centrifugal forces, it is in the top that the stability of the specified parameters is maintained, which causes the high efficiency of the antifoam.
