Description

The invention relates to filtering, and in particular to liquid filters with centrifugal regeneration of the filtering surface, and can find application in engineering, mining, food, chemical and other ⁵ industries.

A known filter for cleaning liquids from impurities, followed by centrifugal cleaning of the filter element, consisting of a housing, a filter element, a rotating shaft with a used liquid sprinkler and an impeller re-cleaning the liquid from sludge [1].

The disadvantage of this filter is a low degree of liquid purification from impurities and low productivity NOSTA _w.

The purpose of the invention is to improve the quality of liquid purification and increase the filter performance.

This goal is achieved by the fact that in the filter containing the housing, the filter element, the nozzle for supplying the source fluid and mounted on a hollow rotating shaft sprinkler, the latter is made in the form of disks fixed to the shaft at an equal distance from each other with a diameter decreasing in height of the shaft, wherein the shaft is equipped with a guide wall mounted at the level of the upper disk, at the base of which holes are made in the shaft for supplying fluid to the sprayer about

It is advisable to make the filter element in the form of a truncated cone, and provide the disks with radial blades mounted perpendicularly on their upper plane at an angle of 120 ° to one another.

The drawing shows a filter, General view.

the filter consists of a cylindrical housing 1 with a pipe 2, provided 3,915 supplying working fluid to the filter,

In the cylindrical housing 1 is placed a filter element 3 made in the form of a truncated cone, the inner surface of which is covered with a filtering cloth 4. Coaxially to the filtering element 3, a hollow shaft 5 is placed inside it and is rigidly connected to it. Over the entire height of the shaft 5, disks'6 are rigidly attached to it with blades 7 located at an angle of 120 ° to one another. Structurally, the disks are made 'increasing in diameter to the base of the filter. Disks on the shaft are mounted evenly and at the same 15 distance from each other.

At the level of the upper disk 6, radial holes 8 are made in the shaft 5 for supplying the filter fluid to the inner surface of the filter element 20. At the same level, in the hollow shaft, a guide baffle is installed 9. In the lower part of the housing 1 there is a collection chamber GO of the filtrate with holes 11 for drainage 15 of the filtrate. Is a device 12 installed under the filter element 3 for removing solid sediment from the filter?

Below the device 12 there is a reservoir 13 for the liquid eo medium that has entered it with a branch 14 for this liquid. The hollow shaft 5 is connected to the drive 15.

the filter works as follows.

The hollow shaft 5 with the filter element 35 3 is driven. The source fluid through the pipe 2 is continuously supplied to the rotating hollow shaft 5 For filtration.

The initial liquid, falling onto the guide wall 9, is ejected by centrifugal force through the openings 8 onto the disk 6, is captured by the blades 7 of the first disk and dumped onto a cone-shaped filter element 3,

The liquid under the action of centrifugal force and impact on the filter element passes through it into the cavity of the housing, flowing into the filtrate collection chamber 10, and through the openings. 11 the filtrate is discharged outward. Particulates and chast.zhidkosti not passed through the filter element from being reflected at an angle under the action of impact and $ ₅ Corollary gravity return to) 4 second and third wheels, the blades of the disks are discharged by centrifugal force on the filtering ele'ment 3 repeating such discharges to the filter element until the last disk 6.

Having passed the path of impacts on the filter element, dehydrated solid particles fall on the device 12 for removing sludge and are carried out. Part of the liquid stomping into the reservoir 13 during the operation of the filter is removed from the outlet through the outlet 14.

The invention provides a longline purification of the original liquid with its separation into liquid and solid fractions, i.e. to the purified liquid and dehydrated, easily removed sludge, increases the efficiency of the filter and the quality of the cleaning of the original liquid.
