RU1768310C - Separator for condensation of suspensions - Google Patents

Abstract

Usage: separation of the density of materials in the food industry. SUMMARY OF THE INVENTION: The separator comprises a drum including a base and a lid, a tray holder with a stack of plates. At the base of the drum, devices are mounted for discharging the condensed suspension. Each of these devices is an inclined mouthpiece having nozzles at the inlet and outlet. Guide means for the thickened fraction are arranged around the circumference of the drum. Guide means are located above the inlet nozzles and are strips. Planks are installed at an acute angle to the drum lid. There is a gap between the cap and the bar for the passage of the slurry. 1 silt

Description

The invention relates to separators with continuous discharge of a heavy fraction through nozzles, and in particular to yeast separators in the food industry.

Known separator for thickening the suspension, containing a drum including a base and a lid, a plate holder with a package of plates installed in the base of the drum of the device for outputting the condensed fraction, each of which is an inclined mouthpiece having nozzle inlet and outlet, and evenly spaced around the circumference drum bases; guiding means for the thickened fraction.

A disadvantage of the known separator is the low productivity due to the low output rate of the condensed fraction, as well as the complexity of the design.

The aim of the invention is to increase productivity and simplify the design.

The goal is achieved in that in the separator for thickening the suspension containing a drum including a base and a cover, a plate holder with a package of plates installed in the base of the drum of the device for outputting the condensed fraction, each of which is an inclined mouthpiece having nozzles inlet and outlet, and guiding means for the thickened fraction evenly spaced around the base of the drum according to the invention, guiding means are placed above the inlet nozzles and are strips, mounted at an acute angle to the drum lid to form gaps between the lid and the bar for passage of the slurry.

The separator comprises a drum including a base 1 and a lid 2, a tray holder 3 with a stack of plates 4, mounted in a drum base 1 of a device for outputting a condensed fraction. Each is indicated (L

ABOUT

of the devices is an inclined mouthpiece 5 having nozzles 6 and 7 at the inlet and outlet of the nozzle 6. The guide means for the thickened fraction are arranged evenly over the inlet nozzles 6. The guide means are strips 8 installed at an acute angle to the lid 2 of the drum with the formation between the lid 2 and the strap 8 of the gap for the passage of the suspension. The central tube 9 serves to feed the initial suspension into the drum. The drum nut 10 is mounted on a vertical shaft 11 having a bearing support 12 of the separator drive. A condensed fraction receiver 13 is mounted under the drum. An impeller 14 is mounted on the drum cover 2 to output a light fraction. Base 1 is secured with cover 2 with nut 15.

The separator works as follows.

The initial suspension is fed through a central tube 9 to a plate package 4. The condensed fraction is concentrated by centrifugal forces at the periphery of the inner cavity of the drum and, through nozzles 6, mouthpieces 5 and nozzles 7, enter the condensed fraction receiver 13 and are removed from the separator. In the inner peripheral part of the drum, the condensed fraction, which is a liquid mixture, rotates at a speed different from the speed of rotation of the drum with

slats 8 installed therein. The stream of condensed fraction is braked by slats 8, increasing the rate of its output through nozzles. In this case, the flow of the mixture, the streamline of the strap 8, is directed into the gap between the straps 8 and the drum cover 2. As a result of turbulization of the flow, sedimentation and adhesion of solid particles to the surface of the drum cover 2 are eliminated.

Thus, the separator allows to increase the rate of removal of the condensed fraction, which increases its productivity. This simplifies the design of the separator.
