Description

The invention relates to the starch industry, namely to equipment for the separation of starch suspensions.

The purpose of the invention is to increase the degree of separation by preventing the undersize product from settling on the inner surface of the nets and the inner surface of the pockets.

FIG. 1 shows a centrifugal-blade sieve, in which a section of two blades is cut, a general view; in fig. 2 - blade, general view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 2; in fig. 5 is a section bb In figure 4; in fig. 6 — node I in FIG. one.

The centrifugal-blade sieve for separating starch suspensions consists of a cylindrical shell 1 and a condenserically placed sleeve 2, between which curved blades 3 are reinforced with equal pitch, each of which consists of a body 4 having openings 5 for the release of undersize product and pockets 6 located in it for removal of the undersize product and mounted on the body 4 of the filtering mesh 7. The walls 8 of the pockets 6 of each blade 3 are inclined towards the openings 5 for the removal of the undersize product, and the angle of inclination of the walls 8 to zhdogo subsequent pocket nadreshetno- downstream movement of the product exceeds the previous tilt angle of the walls.

Filter grids 7 with their bent ends 9 are installed in slots 10 made in body 4 of blade 3. Cylinder shell 1 and sleeve 2 are connected by a bearing disk 11 Blades 3 are fixed to the bearing disk 11 by bolts 12 through holes 13 made in the body 4 blades 3.

Centrifugal-blade sieve works as follows.

The processed product through the slots in the distributor head (not shown) is fed to the filter screen 7, where under the action of centrifugal forces it is divided into sieve - (fiber) and undersize (starch milk) products. The suture product moves along the filtering mesh 7, undergoes additional dehydration and dehumidification, then the air is collected

Coming into a collection of pulps and (not shown).

The undersize product moves along the inner surface of the pockets 6 to the holes 5, made in the case 4 of the blade 3, under the action of the tangential component of the centrifugal force and the airflow and is transported to a collapse of the milk of 1–1 milk (not shown),

The walls 8 of the pockets 6 are made with an angle of inclination o (within 6-40 ° with inclination towards the holes 5. With an increase in the angle of inclination of the internal surface of the walls 8 of each pocket 6, the tangential solenoid is increasing, and the reflection from The air flow deflects the side of the openings for the undersize product, which contributes to an increase in the movement of the supported product along the inner stems: 8 pockets 6 and a decrease in the quantity of pockets: 1) of the filter nets 7.

The proposed sieve design prevents the undersize product from settling on the inner surface of the pockets 6 and on the grids 7, which contributes to an increase in the degree of separation of the product being processed and the stable operation of the centrifugal-blade sieve.
