Description

This invention relates to the separation of solid-liquid suspensions and can be used in chemical and other industrial sectors.

The purpose of the invention is to increase the efficiency of the separation process.

The drawing shows schematically an apparatus for separating suspensions, a general view.

The device comprises a housing 1, a perforated conical shell 2, a shaft 3 passing through the bottom of the housing 1. At the end of the shaft 3 with a disk 4 on which blades 5 are mounted, a perforated horn conical element 6 is fixed. Trapezoidal blades 7 are rigidly fixed above disk 4 and installed from the ground to the perforated conic of the ches-gu. at item 6. In the upper base of the snail chamber 8, a hole 9 with a diameter smaller than the diameter of the upper base of the perforated shell 2 is hollowed out, and a shell 10 is fixed in it. Over the blades 7, the shell 11 is rigidly fixed

is located above the snail chamber 8. In the center of the device is installed, a slurry supply pipe 12, the lower section of which is above the perforated conical element 6, the Snail chamber 8 is located the upper base of the shell 2 and the fitting 13 for the solid phase. The withdrawal of the liquid phase is carried out through the nozzle 14,

A device for separating suspensions works as follows.

The original suspension through the suspension supply pipe 12 falls on a perforated conical element b. Due to the centrifugal force and the pressure force of the gas flow formed by the blades 5, 7, the main part of the liquid phase is forced through the perforated element 6 and is removed from the housing 1 through the tangential nozzle 14. In this case, the particles of the solid phase rise and fall on the perforated face 2 Here, they are pulled by a swirling gas stream exiting the interscapular space, transported along the shell 2, where the liquid film is disrupted from the surface of the particles and the liquid droplets are pressed through the perforation of the shell. yki 2.

The solid phase particles entering the cochlea 8, bounded by the shell 10, are removed from the device through fitting 13. The gas flow, which did not pass through the shell 2, flows through an opening 9 in the upper base of the snail chamber 8 and an annular gap formed by the shells 10 and 11 Next, the flow is directed to the space between the shell 11 and the nozzle 12 for supplying the suspension to the suction region of the blades 7. Thus, the internal circulation circuit is organized. The main part of the gas flow passes with the liquid phase through the perforated shell 2 and the perforated conical element 6, moves in the annular space

between the shell 2 and the housing 1, then it is guided onto the vanes 7 and is twisted again. In the following, the cycle repeats.

The direction of the internal and external circulation circuits in the gas phase is schematically shown in the drawing.

Since the gas phase circuits are closed inside the device, the gas flow quickly vaporizes and the evaporation of the liquid phase does not occur, and the equilibrium between the crystals and the mother liquor is not disturbed.
