[0033] The subject invention, referring to FIG. 1, lies in providing a Cyclone Filter for separating heavy particles from water or any other liquid comprising a Vane (2) to separate Head (1) from separation chamber (4).

[0034] One of the embodiment relates to, referring to FIG. 1-5, a Cyclone Filter for separating heavy solid particles from a liquid, comprising an inlet to introduce the liquid containing heavy particles into a head (1) having an internal shape such that it aids the liquid to follow a circular path within the head (1) and; a vertex pipe (3) having an outlet to lead clean water out of the filter; such that the internal shape of the head enhances the 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 particles of more mass are pushed away from the central axis and towards the wall due to increased flowrate and swirling action; a collection tank (6) to collect the separated particles; characterized in that the vane (2) comprises curved surfaces with substantially elliptical pathways (2A) perpendicular the vertex pipe (3) that further enhances the velocity of flow and its swirling action.

[0035] The internal shape of the head is often circular.

[0036] One of the preferred embodiment of the present invention discloses the pathways to be circular or elliptical.

[0037] Another embodiment of the present invention discloses the shape of the surface of the path is flat or curved.

[0038] Another embodiment of present invention also discloses a Disc (5) on which the particle falls and spread out to be collected on the collection tank (6).

[0039] Yet another embodiment discloses that water/liquid from the pump/other source is entered in to the Head (1) of the filter tangentially with pressure and take substantially circular pathways of the internal structure.

[0040] Another embodiment discloses that the substantially elliptical pathways in the vane makes the stream injected in to the separation chamber (4).

[0041] Further embodiment discloses particles which are moved out by centrifugal action are dropped down along the wall of the separation chamber. Clean water will enter the vertex pipe (3) and comes out.

[0042] Vane design and placement is unique. The vane comprises curved surface thus velocity of the flow is increased drastically with less pressure loss.

[0043] Referring FIGS. 7 and 8, the vane surface is curved which is different from the conventional flat vane. In the flat vane design, space between the two vanes is rectangular where in present design the entry is substantially elliptical and size also optimally designed. Each size of the product to enhance the better flow with less pressure drop.

[0044] Once liquid enters the orifice which is substantially elliptical, the surface on the which the liquid flows is contoured for less friction and enhances the velocity of the liquid. The contour is design shown on the FIGS. 7 & 8 each size. In case of flat vane, friction is high and velocity of liquid is reduced.

[0045] This kind of contoured design has major advantages over conventional flat shaped vane designs. due less pressure drop there less power consumption for user. Also flow rate of the liquid is reduced less. Pressure drop curve (FIG. 6) shows the pressure across different flow rates.

[0046] The swirling action is enhanced by internal shape of head and flow of liquid takes turn around vertex pipe (4). In the course of swirling sand particles are moved out of central axis towards the wall of the Head due centrifugal action. Heavy particles will be moved out first and less mass particles will be next inner circle of the circular flow.

[0047] The present cyclone filter is based on the concept of having uniform pressure across the filter and the separator. Each part is designed by advanced engineering analysis tools for uniform stress distribution in the part and it can sustain impact and creep loads.

[0048] Pressure variation in total system is very less (less than 0.1 bar) so that the system is under less vibration during working. Differential pressure between parts creates vibration and life of the product will be less.

[0049] Vane is designed with uniform wall thickness with unique flow paths and stress distribution is uniform on the part. This kind flow paths can be done by injection molding plastics economically. Therefore, specially developed plastic alloy for manufacturing of vane is opted for. It is blend of Poly Phenylene Ether (PPE), Polystyrene (PS) and Glass fillers. By blending the above three materials, high tensile strength and impact strength is achieved along with abrasion resistance.

[0050] The same stream is entered to the vane (2). Vane has curved surface with substantially elliptical paths (2A) perpendicular the Vertex pipe. While water passing though the vane, velocity of flow is further increased and swirling action is still increased. The substantially elliptical paths in the vane makes the stream injected in to the separation chamber (4). Particles of more mass will be pushed away from the central axis and towards the wall of the Separation chamber. The shape and size of flow paths in the vane decides the efficiency of filtration and pressure drop. The flow paths in the vane are perpendicular to central axis make the efficiency of filtration more. It is shown in the FIG. 3.

[0051] Dropped particles will fall on the Disc (5) and spread out and the same will be collected on the collection tank (6). Collection tank will have drain valve and once it is opened sand particles along with water will be drained out.

[0052] Above product is made of plastic material with UV protection for direct sun light. Different parts are bolted together for easy maintenance. Plastic material is non-corrosive which can handle different quality of water and can work in different environments.

[0053] Filter parts are made up of Polypropylene Glass filled (PPGF) material for high tensile and impact strength. UV resistant materials are blended with above PPGF materials for resistance to direct sun light of products.

[0054] The performance of the present invention is decided by two parameters. One is pressure drop and other is efficiency of filtration at nominal flow rate. The solution provided in present invention ensures that pressure drop is reduced for given flow rate as well as efficiency of filtration also improved.

[0055] Some of the non-limiting advantages of present invention are: [0056] 1. Designed in such a way that no sand/mud particles are stagnated in the Head during shut down. Hence restart of the process will be smooth. [0057] 2. Due to present designs of vane path ways (substantially elliptical), the velocity of the fluid is increased with less drop. Sediments settling on the surface is less as the surface is contoured in circular shape. [0058] 3. Because of the unique design of the vane and positioning of the vane, velocity of the flow is increased drastically and tiny particles are also separated. As pressure drop of our designs are very less, power saving in running the pump is achieved. [0059] 4. Head (1) is bolted with the cyclone separator (4). Also the collection tank (6) is bolted to cyclone separator making the it easy for maintenance. [0060] 5. All parts are made up of specially developed plastic alloy. No corrosion like metal parts in the earlier designs. [0061] 6. Vane shape is designed uniquely which can injection molded economically. [0062] 7. Manufacturing cost is less. [0063] 8. Power consumption is less. [0064] 9. Flow rate (discharge) is more. [0065] 10. no welded joints in the vane and other parts and no corrosion.
