SU1423168A1 - Filtering centrifuge - Google Patents

Abstract

The invention relates to filtering centrifuges and can be used in coal, chemical, mendicant and other industries. The purpose of the invention is to reduce the entrainment of the solid phase with the filtrate. When the centrifuge is operating, the source material is fed to the spreading pin 2, then under the action of centrifugal forces is thrown into the annular chamber 7 of the distributor 3. Gradually, the chamber 7 is filled with the initial material. It then enters the rotor 1. The filtrate through the slits of the rotor is removed to the collection and the sediment to the bunker. 1 il. C (/ cneH3 (jf B

; The invention relates to devices for the separation of liquid inhomogeneous systems in the field of centrifugal forces, in particular to centrifuges, and can be used in COAL, chemical, food and other industries.

The purpose of the invention is to reduce the entrainment of the solid phase with the filtrate.

: The figure shows a schematic filter centrifuge, a vertical section.

I The centrifuge contains a perforated Ionic rotor 1, mounted with a small base up, a spreading cover 2 and a distributor 3 installed on the smaller base of the rotor

1 and covering the spreading cover 2.

The distribution device consists of the upper 4 and lower 5 rings installed at a distance from one another and l: strictly connected by a shell-6 along the outer diameter with the formation of an annular chamber 7.

zom.

The centrifuge is operated as follows: a suspension (material) is fed into the spreading lid 2, from which it is thrown into the annular chamber 7 of the distributor by the action of centrifugal forces.

Chamber 7 is filled with material, which then enters the rotor I, where the separation of the liquid and solid phases takes place. The filtrate through the slots of the rotor is removed to the collection, and the sediment to the hopper (not shown) under the centrifuge.

,; The presence of the annular chamber 7 ensures the supply of the initial suspension with

0 of the spreading lid 2 on the layer of the starting material formed in chamber 7, as a result of which the impact is extinguished and the material is less crushed, less carried away with the filtrate, and in addition, the distributor itself is protected from wear.

Claims (1)

Invention Formula A filter centrifuge containing a perforated conical rotor mounted with a smaller base upwards, spreading a cover and a distribution device mounted on a smaller rotor base and enclosing a spreading cover, characterized in that, in order to reduce the entrainment of solids with a filtrate, the distribution device is made in the form of an annular chamber, the diameter of which exceeds the diameter of the smaller base of the rotor.
