Description

The invention relates to equipment for the separation of liquids in the field of centrifugal forces and can be used in the food, microbiological and other industries.

A centrifugal separator for clarifying a liquid is known, comprising a drum containing a cover with an overflow ring for outputting the clarified product and a plate holder with a tray nut, a receiving-discharge device consisting of a supplying Pat-N chamber, a pressure chamber and a pressure disc, and sealing -cavity of the drum, containing located above the pressure chamber of the hydraulic chamber, formed by the upper and lower lids, the latter of which has an internal annular collar, and a sealing in the hydrochamber ck Јl "

The disadvantage of this separator is the complexity of its design.

The purpose of the invention is to simplify the design of the centrifugal separator.

To achieve this goal, in the proposed centrifugal separator for clarifying a liquid, including a drum containing a cover with overflow, a ring For outputting a clarified product and a plate holder with a stack of plates, a receiving-output device

consisting of a supply nozzle, a pressure chamber and a pressure disc, and a device for sealing the drum cavity, containing a hydraulic chamber above the pressure chamber, formed by the upper and lower covers, the latter of which has an inner collar, and a sealing disk placed in the hydrochamber. the lid has a channel for transferring a portion of the clarified product into a hydraulic chamber whose height is equal to the height of the inner annular collar of the lower lid, while the channel is located on a radius exceeding the inner p overflow ring „

The drawing shows schematically a separator, a partial longitudinal section

A centrifugal separator for clarifying a fluid includes a drum 1 containing a cover 2 with an overflow ring 3 and a plate holder 4 with a bag.

plates 5, the receiving-output device 6, consisting of the supply pipe

7, a pressure chamber 8 and a pressure disc 9, and a device 10 for sealing the cavity of the separator drum, comprising a hydraulic chamber 11 located above the pressure chamber 8, formed by an upper lid 12 and a lower lid 13 with an inner collar 14, and an airtight seal 11 the disk 15, the bottom cover 13 has a channel 16 that communicates the pressure ka-i measure 8 with a hydraulic chamber 11, the height of the channel 16 is equal to the height of the inner ring collar 14, the channel 16 is located on the radius R exceeding the internal radius g of the overflow ring 30 Upper cover 1 2 and the bottom cover 13 with sealing gaskets 17 is connected to the cover 2 by the tightening ring 180. To avoid overflow of the sealing liquid from the hydraulic chamber 11 through the outer annular gap 19, the outer diameter of the inner annular gap 20 exceeds the outer diameter of the outer annular gap 19c. the outlet device is also equipped with an outlet pipe 21 "

The centrifugal separator works as follows.

When the drum reaches the working speed separator, the discharged liquid is fed through the feed nozzle 7 into the internal cavity of the plate holder 4, and then into the peripheral cavity of the drum, from where

it is distributed in the bag of trays 5, where under the action of centrifugal force, heavy particles are thrown into the peripheral part of the slurry cavity of the drum, where they are removed from the separator drum, and the clarified liquid moves into the pressure chamber 8 and fills it to a predetermined level depending on presented to the clarified liquid

From the pressure chamber 8 by means of the pressure disc 9 through the discharge pipe 21, the clarified liquid is removed from the separator drum. At the same time, a portion of the clarified liquid from the pressure chamber 8 through the channel t6 fills the hydraulic chamber 11 to the level of the liquid in the drum of equal radius with the peripheral part of the sealing disc 15 immersed in it. Thus, the gaseous components released from the separated liquid are removed to the atmosphere. preserving the specified properties of the clarified liquid. The sealing device 10 prevents atmospheric air from entering the separator drum 1 when separating liquids, 1 for example, of protein origin. In the process of separation from the hydraulic chamber 11, through the external annular gap 19, a partial evaporation of the liquid occurs, the level of which is replenished with the clarified liquid from the 5 pressure chamber 8 through the channel 16 "

To reduce the entrainment of gaseous components of the clarified liquid through the channel 16 into the hydraulic chamber 11, the channel 16 is structurally made with a small diameter, for example 3 mm, with a height equal to the height of the ring collar 14 "

The device significantly simplifies the design of the centrifugal separator for clarifying the liquid.
