DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to cleaning of a fluid medium from suspended particles and various inclusions and, more particularly, the invention relates to an apparatus for filtering a fluid medium.
This invention can be used very effectively for removing mechanical impurities from chemical products, purification of drinking and circulating water, cleaning of industrial effluents from silt and slag, as well as for air dedusting.
Furthermore, the invention can be used for removing various chemical impurities from liquids and gases and for drying air and gas.
BACKGROUND OF THE INVENTION
Cleaning of liquids and gases from various harmful impurities and solids has presently gained wide application. However, the present-day filtering systems are either bulky or feature inadequate output capacity or have inadequate sealing during their operation, while this parameter is very important when filtering harmful or aggressive media. So far, no efficient devices are available for cleaning agressive fluid media containing a lot of suspended particles, e.g. devices for cleaning effluents from cattlebreeding farms.
Known in the art is an electromagnetic separator comprising a perforated tray located in a magnetic field and rotated by a drive.
This device is disadvantageous because structurally it is overcomplicated.
Also known in the art is an apparatus for filtering liquids comprising a hermetically sealed housing having a slot-shaped opening, through which an endless filtering band is conveyed. The upper portion of the housing is connected to means for supplying a liquid to be cleaned, while the bottom portion thereof is connected to means for removing the clean liquid. The apparatus is also provided with a means for removing filter cake from the band (USSR Inventor's Certificate No. 79,522, BO1 B 33/04, 1948).
A significant disadvantage of this apparatus consists in its low efficiency, since the body features inadequate tightness and this does not allow one to increase the pressure inside this body. In addition, the apparatus has a very complicated design, which practically does not enable reliable sealing to be provided, and this deteriorates the operating conditions of this apparatus.
Another disadvantage of the apparatus is intensive wear of the filtering element (band) in the process of operation due to sticking and solidification of a filter cake on the sealing element mounted in the slot-shaped opening of the body. The cake thus transforms into an abrasive material which wears off the band.
What is more, the inadequate sealing of the apparatus considerably impairs the cleaning quality since a portion of the liquid being cleaned bypasses the filtering member and flows into the bottom part of the apparatus, where the clean liquid is accumulated.
SUMMARY OF THE INVENTION
This invention aims at providing such an apparatus for filtering a fluid medium, which would ensure high hermeticity of the chamber at reduced wear of the filtering element.
These aims are attained by providing an apparatus for filtering a fluid medium comprising a hollow body, a movable flexible filtering member arranged in said body, and means for supplying a medium to be cleaned, removing the cleaned medium, cleaning of the filtering member and removing the cake respectively; according to the invention, the filtering member is shaped as a toroid, while the body is hermetically sealed, ring-shaped and is equipped with slide valves dividing the body space into two portions, one portion communicating, respectively, with the means for supplying the medium to be cleaned and with the means for removing of the clean medium and the other portion communicating with the means for cleaning the filtering element and for removing the cake.
The claimed invention makes it possible to substantially increase the efficiency of the filtering apparatus. This is achieved by providing the apparatus with a ring-shaped body and this much facilitates sealing of the apparatus and makes it possible to clean the filtering member in the proces
