SU452363A1 - Apparatus for separating a suspension in a thin film - Google Patents

Description

This invention relates to separation devices, suspensions. ...

The known device is for separating a B-thin suspension: a film containing a rotor in the form of a body of rotation with a KpaTepoo6pa3HbiMj recess, a housing with collectors of solid and liquid fractions, a feeder and an annular filter septum located with a gap around the rotor.

The purpose of the invention is to increase the degree of dehydration of the condensed 4 stocks. For this, the proposed device is provided with a lid with a drive mounted above the ronor along its axis, and a ring filter partition is fixed on the lid and made expanding in the direction of gravitational forces.

The drawing schematically depicts the device being described.

Slurry separation device

It contains a rotor 1 with a crater-like recess 2, a body 3 with collectors 4 and 5, respectively, of a solid and liquid dressing cage, a feeder 6, a filtering partition. 17 and a cover 8 with a drive. I

The device works as follows

The initial suspension through pipe 9 of feeder 6 is fed to the separating surface of the rotor 1, through which it spreads in a continuous thin film.

The solids under the action of centrifugal forces are detached from the surface of the film and are thrown onto the filter septum 7, and the liquid fraction flows down the peripheral edge into the collector 5.

When hitting the filter septum, the solid particles are thrown into the hopper 1O for solid sediment, and the liquid droplets that have flown out together with the particles pass through the openings of the partition 7 into the collection 5.

Since the filter septum is made expanding in the direction of gravitational forces, solid particles hitting it will be thrown into the solid fraction collector 4 without interfering with the passage of liquid through the partition. This increases the degree of obezhzhzhivan and prevents clogging of the openings of the septum 7.
