SU442844A1 - Centrifugal separator with pulsating discharge of sediment - Google Patents

Description

The invention relates to the field of separation of liquid inhomogeneous media in the field of centrifugal forces.

A centrifugal separator with pulsating discharge of sediment is known for separating liquid inhomogeneous media, such as microbiological suspensions, made in the form of a drum mounted on a vertical shaft, including a base with a buffer liquid chamber, a lid, a package of conical plates and a series of piston valves for draining inter-slurry liquid

In order to reduce the moisture content of the sludge, the proposed separator is equipped with a series of piston valves for sludge unloading, installed along the periphery of the drum and connected to the buffer liquid chamber, while the sludge discharge valves and the inter-tray liquid are made with hollow pistons and outlets

Fig, 1 shows the proposed centrifugal separator; Fig.2 valve.

On a vertical shaft; I has a drum, comprising a base 2, a cover 3 and a package of conical inserts 4 mounted on the plate holders 5,.

At the base of the drum there are two chambers 6 and 7 for a buffer fluid that are connected to valves 8 and 9 by channels 10.

The valve contains a working cavity II, in which the hollow piston 12 moves, opening the output channels of the IS. The channel 10 is connected to the at-: the sphere by the jet 14,

The separator works in the following way.

During the separation, the suspensions 1slaps 8 and 9 are closed. After the sludge space is filled with sediment, the slurry feed ceases; through chamber 6 through channel 10 into the working cavity II of valve 8

buffer capacity is given. From the pressure created by the buffer smoothness, the hollow piston 12 x valve

8 moves and opens the olcler 14, the interparticle liquid flows out through the central hole in the piston 12 1 of the valve 8, gets into the outer chamber of the separator, and returns to re-separation,

The supply of buffer bladder into chamber 6 is stopped, its remnants are removed from channel 10 of juhapan 8 through} 1y1kler, piston of Yyapan 8 under the action of centrifugal forces closes channels 13, Yugapan 8 is closed

Then the buffer is fed into chamber 7, the valve opens.

9 and sediment from the drum sludge space is discharged to the receiver. Valve 9 operates according to the same scheme as valve 8. After unloading the sediment, the supply of buffer fluid to chamber 7 is stopped, valve V is closed.

THE INVENTION OF THE INVENTION

A centrifugal separator with a pulsating discharge of sediment for separating liquid inhomogeneous media, such as microbiological suspensions, made in the form of a base mounted on a vertical shaft of the drum B1 with a base for a buffer chamber, a lid, a package of conical plates and a series of piston valves for draining the dish tray fluid, a separate package of plates and a series of piston valves for draining the inter-tray liquid, which features a tray of trays that, in order to reduce the moisture content of the sludge, it is equipped with a piston valve for unloading the sludge installed on the periphery of the drum and connected to the chamber Liquids, with valves for discharging precipitate and a liquid drain mezhtarelchatoi formed with hollow pistons and output hslapanami.
