The filter is equipped with additional disks with blades 16, 17 installed above the wheel with blades 13 and the perforated element 5 evenly spaced along the height, and the bottom 7 of the chamber 6 is designed as a strip rising along a helical line. 3 hp f-ly, 2 ill.

Description

I;

The invention relates to filtration and can be used in the chemical and other industries for the separation of heterogeneous liquid products.

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

FIG. 1 shows schematically a filter for separating suspensions, a general view; FIG. 2 is a section A-A in FIG. one.

The filter contains an outer shell 1 with a nozzle 2 for outputting the liquid phase, a spherical bottom 3 with a shell 4. In the upper part of the inner perforated element 5, a chamber 6 is installed for introducing the suspension into the filter, bottom 7 which is made in the BHjge upward along the helix

strip, and the inlet of the suspension 8 is installed tangentially to the element - 3. In the bottom of the chamber 6 a hole is cut from which the pipe 9 departs. In the lower part of the element 5 it is tangentially mounted to the outlet 10 for unloading the solid phase. The axis of the element 5 has a shaft 11 on which a wheel 12 with mirrored blades 13 and additional disks 14, 15 equally spaced at the height of the element 5 are mounted, mounted above the wheel with blades 13, at the height of element 5.

The filter works as follows. .

The initial suspension through the pipe 8 is fed into the chamber 6, rises along the helix and overflows

into the perforated element 5. At the expense of the same axial and circumferential flow rates of the suspension, around the inner wall of chamber 6, over the entire perimeter, turning over the kicked surface of element 5 is uniform. Next, the suspension is picked up by a swirling gas flow. 5. It forms during rotation of the shaft with G7 blades, twists and is pressed to the perforated wall of the element 5. After the centrifugal forces creates an increased pressure on the wall of the elomeite 5, under the action of which the liquid phase is pushed through the perforations, collects in the lower part of the body and vsodit ™ s through the pipe, 2 ,. As the slurry with separated particles progresses downward, the solid phase exposes ™ with the effect of increasing centrifugal forces from the action of OP 16j blades, the height and curvature of which decreases to the bottom while simultaneously increasing the diameters of the discs 14,15. - The separation. Particles are discharged through pipe 10 and then the cycle repeats. With section- m i i suspensions, 5 of the Kyörths, the specific mass of the solid phase is less than the liquid one, - and the coercion concentration of the thierd phase is low,. in the bottom b there are an opening in the hole that connects it to the pipe 9 that does not reach the bottom of the outer shell I

This will separate part of the liquid phase. There may be several such taps.
