Hydroclone

The hydroclone is the device intended for water purification from mechanical (generally sand) and other particles which density is higher than water density. Hydroclones widely apply in the course of preparation of water at drop watering. The hydroclone consists of cylindrical part with a branch pipe for tangential input of a pulp under pressure of 0,5 — 3 bars and conic part with a corner of conicity 10 — 20 °.

Principle of action of a hydroclone.

At conic part of a hydroclone the peskovy nozzle through which impurity unload is provided. The feeding branch pipe of a hydroclone is located in such a way that the pulp is entered on a tangent and rotates in it with formation of external and internal streams. Firm particles are affected by centrifugal force and are rejected to hydroclone walls. The more the mass of grain, the closer with a wall it will be rejected. The grains having the big weight, than boundary grains on which division is made remain in an external stream and, moving to hydroclone cone top, unload through a peskovy nozzle. Grains with a smaller weight get to internal. a stream are also taken out through a drain opening of a hydroclone. For increase in productivity hydroclones can be packed in batteries on some pieces.
