SU1242241A1 - Filtering centrifuge - Google Patents

Description

The invention relates to equipment for the treatment of suspensions in a centrifugal field, namely filter centrifuges, and can be used in the food, medical and petroleum refining industries.

The purpose of the invention is to increase the reliability of the centrifuge.

Supplying the rotor drums with floats and placing them in the housing allows reducing the loads on the axes of the rotors and improving the conditions for regeneration of the filtering elements, which leads to an increase in centrifuge reliability.

FIG. 1 shows a centrifuge, a longitudinal section; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. one.

The filtering centrifuge contains c.vion rotor body 2 on the drive shaft, device 3 for loading the suspension, collection of filtrate 4, pipe 5 for taking out sediment and a rotor including a number of drums 6 mounted on axes 7 rotatable around them. On the x 7 axis, the floats 8 are rigidly fixed. The drums 6 are equipped with filtering elements 9 and radia. 10 septum rigidly connected with floats 8, and housed in housings 11 having pheels 12 for loading cycneiianH and apertures 13 for draining the centrate.

The centrifuge works as follows (. "Scam JOM.

When cranking the drive shaft 1, the rotor body 2 and the drums 6 rotate.

The battered suspension is fed through the loading device 3 to the filtering elements 9 located opposite the loading slots 12 in the housings 11 and dehydrated. The sediment accumulates on the filter elements 9 between the radial walls I), and the filtrate is in the housings 11. The housings 11 are filled with filtrate to the level of the holes 13 for draining the latter. As sediment accumulates on the filtering elements 9, the aeration 14 of the reels 6 is turned on, which rotate relative to the axes 7 until under the action of centrifugal forces the sediment is discharged into the nozzles 6 to output the latter will not occupy the position of the previous one. With a further rotation of the drums, the filter elements of the filter 9, freed from wasps ;; 1ka, ps are loaded into the filtrate located in the housings 11, and) are regenerated. Upon further turns of the liOB 6, the regenerated filtering elements 9 are again located opposite the loading slots 12, and the process is repeated.

When working centrifugal centrifuges si. Ps, caused by the lies of the reels 6 together with the rotor body 2 and acting on the axis 7, are balanced by the buoyancy forces, and this part of the reels 6 with the floaters S, which is submerged by the FS filtrate in the cases I. As a result, i; a- 1 ruzki, perceived axes 7. sharply CISH-, which leads to an increase in the ides of the centrifuge as a whole.
