Abstract

The invention relates to devices for the mechanical purification of liquids and improves its efficiency and quality. The filter consists of a housing 1, a filtering cone 2, a diversion chamber 3 with a nozzle 4, a cylindrical shell 5, a casing 6 and annular channels 7 and 8 that communicate with each other in the conical part of the housing. Inside the casing 6 a screw 9 is placed, on the shaft of which there is an impeller 10 and scrapers 11 having the possibility of axial movement, made in the form of blades parallel to the cone 2 forming. Tangentially to the shell 5 there is a nozzle 14 for introducing the filtered liquid. In the lower part of the housing, a settling chamber 15 is fixed, connected to the lower part of the casing 6 by suction nozzles 16. Suspend the fluid flow from the screw 9 and scrapers 11 are thrown into the annular channel 7. Due to ejection, the suspension goes to the outlet and then to the settling chamber 15. Purified the liquid enters the discharge chamber 3 and through the pipe 4 is removed from the filter. 3 il.

Phage 1

Isobrotin is a device for the mechanical purification of liquids and can be used in water treatment systems.

The purpose of the invention is to increase the efficiency and quality of cleaning liquids

FIG. 1 shows schematically a filter; in fig. 2 - node I in FIG. 1; in fig. 3 shows section A-A in FIG. 2

The filter for cleaning liquids consists of a housing 1, to the upper end of which, with its large base, a filtering cone 2 and a diversion chamber 3 with a nozzle 4 for draining the filtered fluid are fixed. In the cylindrical part of the housing 1 there is a shell 5, a housing 6 and annular channels 7 and 8 communicate with each other in the conical part of the housing 1. Inside the casing 6 there is a screw 9, on the shaft of which the impeller 10 is fixedly mounted and the scrapers 11, which can be axially displaced in the form of blades parallel to m cone 2. The scrapers 11 in the upper part connected with the piston 12, and the bottom - with the sleeve 13. The axial movement of the scraper 11 is performed within the clearance If. Tangentially to the shell 5 there is installed a nozzle 14 for introducing the filtered liquid located in the plane of the impeller 10. In the lower part of the housing 1 a settling chamber 15 is fixed, connected to the lower part of the casing 6 by suction nozzles 1 6.

The filter works in the following way.

The nozzle for draining the sediment from the settling chamber 15 is silenced. The filtered fluid under pressure is fed into the housing 1 through the liquid's Strou pipe, into the cavity of the annular channel 8 through the tangential nozzle 14, hits the paddles of the impeller 10, driving it to rotate. Torque from the impeller 10 cher shaft of the screw 9 is transmitted to the scrapers 11 Mechanical impurities that are in the rotating fluid are concentrated near the inner wall of the shell 5 and under the action of centrifugal and gravitational forces move

down to the outlet in the conical bottom of the housing 1 ,.

Sharp expansion of fluid flow

In the DRAINING chamber 15, which emerges from the opening in the conical bottom of the housing 1, it provides a significant reduction in the flow velocity, which contributes to the separation of mechanical impurities from the liquid. The sediment accumulates on the sloping bottom of the settling chamber 15 at the branch pipe to drain sediment. Under the action of excess pressure in the settling chamber 15 and the directional movement created by the screw 9, the clarified liquid enters the internal cavity of the casing 6 through the nozzles 9. 2о Floating suspensions, located in the clarified liquid, fall on the outer surface of the filtering cone 2 o Under the action of the pressure of the liquid on the piston 12 rotating

the scrapers 11 are raised upward by the size of the gap y until they touch the outer surface of the filter cone 2 and clean the outer surface of the filter cone 2

from sticky suspensions. Suspend the flow of fluid from the screw 9 and the side surface of the scrapers 11 are thrown into the annular channel 7 due to the centrifugal force.

created by the flow in the annular gap between the housing 1 and the shell 5, floating suspensions located in the annular channel 7, go to the outlet in the conical bottom

the casing 1 and then into the settling chamber 15. The purified liquid enters the upper part of the housing 1, into the discharge chamber 3 and through the nipple 4 is withdrawn from the filter. In the initial position of the scraper 11, under the action of the force of gravity, they are lowered down by an amount of about
