Abstract

A cyclone filter for separating heavy particles from water or any other liquid including a head to introduce the liquid into the filter, causing the liquid to swirl enhanced by an internal shape of head and flow of liquid takes turn around vertex pipe, the liquid containing solid foreign matter, a vertical vertex pipe to lead clean water out of the filter, a vane to separate head from separation chamber, a hollow cylindrical separation chamber where particles of more mass will be pushed away from the central axis and towards the wall due to increased flowrate and swirling action, a collection tank to collect the dropped particles, where the vane includes curved surfaces with substantially elliptical pathways perpendicular the vertex pipe that enhance the velocity of flow and its swirling action.

Claims (15)

1 . A cyclone filter for separating heavy solid particles from a liquid, comprising:

an inlet to introduce the liquid containing the heavy solid particles into the cyclone filter;

a head ( 1 ) having an internal shape such that the head aids the liquid to follow a circular path within the head ( 1 );

a vertex pipe ( 3 ) having an outlet to lead clean water out of the cyclone filter; such that the internal shape of the head enhances swirl of the liquid around the vertex pipe ( 3 );

a vane ( 2 ) to separate the head ( 1 ) from a hollow cylindrical separation chamber ( 4 ); such that the heavy solid particles of more mass are pushed away from a central axis and towards a wall due to increased flowrate and swirling action; and

a collection tank ( 6 ) to collect the separated heavy solid particles;

wherein the vane ( 2 ) comprises curved surfaces with substantially elliptical pathways perpendicular the vertex pipe ( 3 ) that further enhances velocity of flow and the swirling action, and the vane has an elliptical cross section to provide less pressure variation in total system so that the total system is under less vibration during working.

2 . The cyclone filter as claimed in claim 1 , wherein the substantially elliptical pathways are replacing circular or rectangular pathways.

3 . The cyclone filter as claimed in claim 1 , wherein the substantially elliptical pathways are elliptical.

4 . The cyclone filter as claimed in claim 1 , comprising a disc ( 5 ) on which dropped particle falls and spread out to be collected on the collection tank ( 6 ).

5 . The cyclone filter as claimed in claim 1 , wherein water/liquid from a pump/other source enters into the head ( 1 ) of the cyclone filter tangentially with pressure and take the circular path of the internal shape.

6 . The cyclone filter as claimed in claim 1 , wherein the heavy solid particles which are moved out by centrifugal action are dropped down along the wall of the hollow cylindrical separation chamber and the clean water will enter the vertex pipe ( 3 ) and come out of the cyclone filter.

7 . The cyclone filter as claimed in claim 1 , wherein the cyclone filter is made of plastic material with ultraviolet (UV) protection for direct sun light.

8 . The cyclone filter as claimed in claim 6 , wherein filter parts are made up of polypropylene glass filled (PPGF) material for high tensile and impact strength.

9 . The cyclone filter as claimed in claim 1 , wherein the vane is made by blending Poly Phenylene Ether (PPE), Polystyrene (PS) and Glass fillers to achieve high tensile strength and impact strength along with abrasion resistance.
