Description

The invention relates to centrifugal technique and can be used in the food; chemical, pharmaceutical and other industries for the separation of liquid heterogeneous systems.

The purpose of the invention is to increase the reliability of the operation of the separator by removing sediment from the buffer liquid.

In Fig.1 schematically shows the proposed separator, a General view; in fig. 2 - valve incision; fig.Z-the same option.

The centrifugal separator contains a bed 1 and a drum 2 mounted on a vertical shaft consisting of cover 3, base A, plate podderzhatel 5 with a package of plates 6, located at the base 4, the movable bottom 7 and the hydraulic system.

The hydraulic system includes a channel 8 for supplying a buffer fluid and at least one valve 9. The latter consists of a valve casing 10 having a ka-. There is an output 11 of the buffer fluid, movable fluid 12, having a notch 13 at one end, and a sealing valve 1A. In the movable piston 12 and the sealing valve 14, the channels 15 are made for the output of the bogey liquid connected to the channel 11 of the output of the buffer liquid in the holder 10 of the valve 9 (figure 2). The inner surface of the recess 13 of the movable piston 12 is made conical.

Between the valve housing 10 and the movable piston 12 there is an annular cavity 16 which communicates with the channel 8. The cavity under the movable bottom 7 communicates with the valve 9 with the channel 17. The channel 15 in the sealing valve 14 can be made concentric with the axis of the valve 14 (FIG. 3).

Centrifugal separator operates as follows.

When the drum reaches 2 working revolutions, buffer fluid is supplied to the hydraulic system, which raises the movable bottom 7 to the upper position. The movable bottom rests on Krishka 3 and closes the discharge gaps of drum 2. Excess buffer fluid flows through channel 8 into the annular cavity 16, from where it penetrates through the gap between the movable piston 12 and the yoke 10 into the recess 13 and then under the action of centrifugal forces

is removed through channels 15 and 11 (. FIG. 2). When channel 15 in the sealing valve 14 is concentric with the axis of the latter, the buffer fluid together with the sediment particles in it accumulates in the floors 15 and is removed from them only during unloading (fig.Z). Subsequently, the supply of buffer liquid is stopped or a small amount of it is supplied (Fig. 2). Next, a separable product is fed into the separator, which, via the plate holder 5, passes through the plate holder 5 into the bag package 6, where it is subjected to separation. The sediment settles in the slurry

drum 2 space. To discharge it, an additional portion of buffer liquid is supplied in an amount that exceeds its flow through the channels.

15. The pressure in the cavity 16 increases, and the movable piston 12 together with the sealing valve 14 moves to the axis of rotation of the drum 2 and opens the channel 11 of the output buffer

fluid in the valve cage 10. Buffer fluid from under the movable bottom 7 through the channels 17 and 1I is removed from the drum. The movable bottom 7. Moves down and opens the discharge.

drum slots 2 through which sediment is removed from the slurry space. The duration of the discharge depends on the duration of the supply of an additional portion of buffer liquid,

After the additional supply is stopped, the buffer fluid is removed through the channels 15, the pressure in the cavity 16 drops, and the movable piston together with the sealing valve 14

moves under the action of centrifugal forces from the axis of rotation, blocking the output of the buffer fluid from the channel 17. The movable bottom 7 rises to the upper position, and the separation process continues.

Thus, the use of the invention makes it possible to increase the reliability of the separator by removing all sludge from the buffer fluid in the valve.
