The filtering elements 7 are dvd conical perforated dms mounted on an annular pressure channel 12, tapering to the periphery of the rotor. A dissectate is arranged in a checkerboard pattern in concentric circles: .. The invention relates to devices for separating suspensions into Solid and Liquid fractions in a centrifugal field, namely centrifuges, and can be used in agriculture for separation manure in fractions, as well as in the chemical, mining and other industries,,. ; V ...-. :. The purpose of the invention is to increase productivity and separation quality. . Figure 1 is a schematic view of a centrifuge for separating suspensions, a general view; figure 2 - section a - a in figure 1; on fig.Z - node B in figure 1; figure 4 - node In figure 1; on fig.5 - node G in figure 2,

 The centrifuge for separation of suspensions contains a housing 1 with collectors 2 of IS for

 sediment and filtrate, housed in housing: 1 rotor 4, including a distribution chamber 6 mounted on the drive shaft 5 and filter elements 7 mounted on its outer surface with casings 8 for collecting the filtrate, a supply pipe 9, the outlet section of which is located distribution chamber 6.

Filtering elements 7:

in the form of two conical perforated disks 10 and 11. established with the formation

between them an annular pressure head: channel 12, tapering to the periphery of the rotor 4.

.Inside channel 12 at concentric 6k. The chessboard is placed in a checkerboard pattern. Flow dividers in the form of corners 13,

facing the top of the distribution chamber 6, the Corners 13 are perforated. and equipped with trays 14 for collecting the filtrate, communicated with the cavity of the casings 8 through holes 15 in

disks 10 and 1 |.. A centrifuge for: separating suspensions V operates as follows. . .:,. Suspension is fed through pipe 9 to the dispensing chamber b, from where, under the influence of centrifugal forces, it enters the pressure channel 12 between the disks 1.0 and 11, where it is gradually compressed and freed from the filtrate, which through the perforation of the disks 6 the cavity of the casings 8 flows, from where it is discharged to collector 3 for filtrate. Precipitate centrifuge flow. Dividers are angles facing the top of the distribution chamber. Corners can be perforated. In this case, they are provided with trays for collecting the filtrate, which are in communication with the cavity of the casings through openings in the disks. 1 s.p. f-ly, 5il.

forces are thrown into chamber 2 by running forces

and is brought out. When moving in

radial direction in space

between disks 1.6 and 11 the suspension flow

meets on its way dividers in the form

corners 13, as a result of which the torus partially slows down, mixes vigorously and is-; changes the trajectory of its movement. Next, the stream encounters the following

in the direction of movement the corner ki bifurcates again | into two streams with simultaneous mixing, which facilitates the separation of the filtrate and its removal into the cavity of the fire 8.. :,. : When meeting with corners 13, which are formed in the form of perforated walls with pallets 14, additional extraction of the filtrate is ensured, which flows through the perforation: into the pan and then goes through holes 5 on the disks 10 and 11

... Feasibility

The proposed centrifuge for separating suspensions consists in increasing the productivity by 10-15% and the quality of separation to 20-25% by increasing the filtering surface, as well as increasing the squeezing forces when the suspension moves. In the channel narrowing to the outlet. . :,,
