Description

one

The invention can be used in sugar processing industry for processing massecuites.

The known filter centrifuge containing a housing, a perforated rotor: with a filter sieve, a coaxially accelerating pot with it and a device installed above the latter for even distribution of suspensions in the rotor.

The aim of the invention is to increase the efficiency of the process of separation of suspensions with a high content of the liquid phase.

This is achieved by reinforcing between the accelerated pot and the device for evenly distributing the suspension in the rotor an insert for pre-separating the liquid phase from the solid, consisting of an outer continuous and intrapertured perforated shells between which there is an annular chamber for collecting and draining the liquid phase.

Moreover, the inner perforated shell is cylindrical, and

; the rifle is solid - conical with an angle Between the generator and the axis equal to or; more than 1 friction slope (mainly 5-10 °) this acceleration pot is mounted with the possibility of moving

. verticals In addition, on the rotor filter sieve and the inner perforated shell are the end-sections {Protective sieves are located, which have forming slots on each side to form a gap with the filter sieve and the shell.

FIG. 1 shows the described centrifuge in section, general view; in fig. 2 wall rotor with sieves; in fig. 3 - then

same, cross section.

The described filtering centrifuge contains a casing 1 in which a perforated rotor 2 is placed with a filtering sieve 3. In the rotor 2 there is a coaxial arrangement

an earthing pot 4 and a device 5 mounted above the latter for uniform distribution of the suspension in the rotor. Between the accelerating pot 4 and the device 5 8 of the rotor, insert 6 is fixed

pre-separating the liquid phase from the t-cord. The insert 6 consists on the inner perforated 7 and the outer continuous 8 shells, between which is located on the collar chamber 9 for collecting and the liquid outlet phase. Vstrenna in. the perforated shell 7 is cylindrical, and the outer continuous shell 8 is conical with an angle between the generatrix and the axis equal to or greater than the friction slope (mainly (5-1 for adjusting the length of the filtering zone and, consequently, the degree of pre-separation of the liquid phase Accelerating pot 4 is mounted with the ability to move vertically.The filter sieve 3 of the rotor 2 and the perforated shell 7 rest on the bed screens 1O, The rotor 2 consists of track 11 and the strips welded to them 12. On the filter sieve 3 and the inner Perforated shell 7 contains protective sieves 13, which have forming stages 14 to form a gap 15. Protective sieve 13 has holes 16 with walls 17 and 18. The centrifuge works as follows: The suspension goes through accelerator pot 4 to perforated cover 7 of insert 6 The liquid phase partially goes through the perforated shell 7 to the SSH shell 8 is discharged into the casing 1. The pre-condensed product enters the device 5 to evenly distribute the material being processed and then to the rotor 2, where roiskhodit eye definitively zhihzhoy phase separation. The sediment under the action of centrifugal forces moves along the rotor 2 and is unloaded into the casing 1. Separation of the liquid phase By means of an insert with an adjustable length of the filter zone, it allows the massecuite to feed into the rotor with the optimum concentration of the solid phase, thereby increasing separation efficiency and increasing centrifuge productivity and. The subject matter of the invention is 1. A filtering pentrifuge containing a casing, a perforated rotor with a filter sieve, paradise, an accelerating vat placed therein and a device installed by the H8C to evenly distribute suspensions in the rotor, so that it can be increased. The efficiency of the process of separating suspensions with an increased liquid phase content between the accelerator pot and the device, to evenly distribute the suspension in the rotor (y1 $) is one insert dp pre-separating the liquid phase Ci from the solid, consisting of an outer solid and inner perforated shell, between which an annular chamber for the collection. and removal of the liquid phase. 2. A centrifuge according to claim 1, that is, with the fact that the inner perforated shell is cylindrical, and the outer solid is conical with an angle between the generator and the axis equal to or greater than the friction slope, mainly 5-10 ° 3. Centrifuge on PP. 1 and 2, that is, with the fact that usko} an efficient pot is installed with the possibility of moving along the vertical. 4. Centrifuge on PP. 1 and 2, on which the protective sieves are located on the rotor filter screen and the inner perforated shell of the insert, having PS forming protrusions to form a gap with the filter screen and shell.
