Description

The invention relates to equipment for the separation of liquid mixtures in the field of action of centrifugal forces and can be used in food, meat and dairy, medical and other industries.

A known separator for separating liquid, comprising a drum mounted on the drive shaft with a conical insert package having channels for supplying the liquid to be divided into the gaps between the latter. ;. ·

The technological throughput of these separators is mainly limited by the number and size of the supply channels [1].

However, an increase in the diameter of the supply channels in such structures leads to a decrease in the working surface of the conical inserts, a shift of the liquid interface on the fractions in the drum from the calculated one, and, ultimately, to a decrease in the efficiency of the separation process.

The purpose of the invention is to increase productivity and improve the quality of separation.

This goal is achieved in that in a separator for separating liquid, including a drum mounted on the drive shaft with a conical insert package having channels for supplying the divided liquid to the gaps between the latter, the inserts consist of at least two coaxial cones having a common generatrix installed above the other with an annular gap and connected by jumpers, while the channels of the package have a slit-like shape.

In FIG. 1 schematically shows a separator separator; on. 2 conical insert; in FIG. 3 - package conical inserts, section.

The separator separator contains a drum 1 mounted on a shaft 2

889 of drive 3 and having a package of conical inserts 4. Insert 4 is made of two coaxial cones 5 and 6, mounted one above the other with an annular gap A and connected by jumpers 7. Jumpers 7 form supply channels 10 with edges 8 and 9 of cones 5 and 6 slit-like form. In some separator separators, the conical inserts 4 have additional channels (not shown) arranged concentrically with respect to the main supply channels 10 at the periphery of the inserts 4. For such separator separators, the conical inserts are made up of three coaxially arranged cones mounted on top of each other above each other with annular gaps connected by jumpers with the formation of two rows of concentrically arranged slit-shaped channels - the main supply and additional.

The separator works as follows.

The fluid through the vertical pipe 1.1 enters the chamber 12, from which through the supply channels 10 it enters the gaps 13 between the conical inserts 4. In the gaps 13, under the action of centrifugal forces arising from the rotation of the drum 1, the liquid is divided into light and heavy fractions and released draft. Light fractions are displaced to the center of the drum 1, while heavy fractions rush to its periphery and are discharged respectively by discharge pressure disks 14 and 15. The sediment is collected from the liquid in a collector 16, from which it is removed manually or automatically by known methods.

In the case of conical inserts with two rows of channels - the main supply and additional through the main supply channels, as in the known constructions, the liquid is supplied from the chamber 12 into the gaps 13 between the inserts, and through the additional channels, the heavy fraction or some intermediate one is removed.

The separator provides greater throughput compared to the known separator separators by increasing the size of the 5 feed channels.

Moreover, the execution of the latter in the form of slots clearly ensures a predetermined design position of the cylindrical liquid interface on the Yu fraction in the drum, as well as uniform filling with liquid of the upper and lower, relative to the feed channel 10, portions of the gap 13 between the conical inserts. This significantly increases the efficiency of the technological separation process by the proposed separator-separator in comparison with the known ones. The capacity of the proposed separator separator increases by 20-30%, while there is a more efficient separation of the liquid, simulating some food products,

Thus, the economic efficiency of the proposed separator-separator is achieved due to a significant increase in unit throughput, i.e. separator performance.

Claims (1)

The invention relates to equipment for the separation of mixtures in the field of centrifugal forces and can be used in the food, milk, medical and other industries. A separator for liquid separation is known, which includes a drum mounted on the drive shaft with a package of conical inserts having channels for supplying the liquid to be divided into the gaps between the latter. ;. The technological capacity of these separators is limited mainly by the number and size of feed channels 1. However, an increase in the diameter of the supply channels in such structures leads to a decrease in the working surface of the conical inserts, displacing the interface of the liquid into fractions in the drum from the calculated one, and, ultimately, to a decrease in the efficiency of the separation process. The purpose of the invention is to increase productivity and improve the quality of separation. This goal is achieved by the fact that in a separator for separating a fluid, including a drum with a package of conical inserts mounted on the drive shaft, having channels for supplying a separable fluid into the gaps between the latter, the inserts consist of at least two coaxial cones having a common forming installed one above the other with an annular gap and connected by bridges, while the channels of the package are slit-like. FIG. 1 schematically shows a separator separator; on. 2 conical insert; in fig. 3 - package of tapered inserts, cut. The separator separator contains a drum 1 mounted on the shaft 2 of the drive 3 and having a package of conical inserts. The inset -t is made of a composite of two coaxial cones 5 and 6, mounted one above the other with an annular gap A and connected by bridges 7, Bridges 7 form with edges 8 and 9 cones 5 and 6 feeding channels 10 of a slit-like shape. In some separator separators, conical inserts k have additional channels (not shown) located centrally with respect to the main supply channels 10 at the periphery of the inserts. For such separator separators, conical inserts are made up of three coaxially arranged cones mounted one above the other with annular gaps, connected by bridges with the formation of two rows of concentrically arranged slit-shaped channels — the main feed and additional ones. The separator works as follows. The liquid through the vertical pipe 1 1 enters the chamber 12, from which the feed channels 10 pop into the gaps 13 between the conical inserts k. In the gaps 13, under the action of centrifugal forces arising from the rotation of the drum 1, the liquid is divided into light and heavy fractions and precipitation. Light fractions are displaced to the center of the drum 1, and the heavy ones rush to its periphery and are retracted discharge discharge discs and 15- The precipitate from the liquid is collected in a collector 16, from which it is removed by known methods, manually or automatically. In the case of conical inserts with two rows of channels — the main supply and additional channels — as in known structures, liquid is supplied from chamber 12 to the gaps 13 between the inserts, through additional channels or any about interstitial. 1. 4 The separator is provided with a large capacity compared to the known separator separators by increasing the size of the supply channels. At the same time, the implementation of the latter in the form of slots clearly ensures the specified calculated position of the cylindrical interface of the liquid into fractions in the drum, as well as uniform filling, with liquid, upper and more, relative to the feed channel 10, part of the gap 13 between the conical inserts. This significantly increases the efficiency of the separation process offered by the separator-separator compared to the known ones. The capacity of the proposed separator separator is increased by 20-30, with a more effective separation of the liquid that simulates some food products. Thus, the economic efficiency of the proposed separator separator is achieved due to a significant increase in unit throughput, i.e. separator performance. Claims of the Invention A separator for separating a fluid, including a drum mounted on the drive shaft with a package of conical inserts having channels for supplying the liquid to be divided into the gaps between the latter, so that, in order to increase productivity and improvement of the quality of separation; the inserts consist of at least two coaxial cones having a common generator, mounted one above the other with an annular gap and. bridged, with the channels of the package are slit-like.
