Description

AN IMPROVED HYDRO CYCLONE FILTER

FIELD OF INVENTION:

The present invention relates to an improved hydro cyclone filter. In particular the present invention relates to an improved hydro cyclone filter that provides clean, filtered water to be used in irrigation. It provides hydro cyclone filter that identifies the rubbing or grinding of the components of the hydro cyclone filter without opening the said hydro cyclone filter. The present invention provides substantially increased shelf- life of the hydro cyclone filter yet is cost effective and user friendly.

BACKGROUND OF INVENTION: Hydro cyclones are widely employed in various industries for separating operations. They are used for removal of undesired particulate material from liquids, dewatering or concentrating operations or for classification of solids. For use of hydro cyclones in irrigation, water is either sourced from ground, canals or rivers which contains sand particles of different sizes. Hydro-cyclone Filter is installed to filter out the slightly big sand particles or small pebbles preventing it from choking the pipe lines, especially drip irrigation pipelines. Water is pushed with pressure from inlet chamber of the hydro-cyclone filter which creates the hydro- cyclone force in the water (mixed with sand particles) .The hydro-cyclone force leaves the bigger sand particles or small pebbles, in the flush tank beneath the filter and throws the clean water from outlet chamber. The long term use of the hydro cyclone filter causes wear and tear of it and decreases the shelf life of the hydro cyclone filter. Continuous circular flow of water mixed with sand particles, inside the filter leads to grinding or rubbing of the inner body of the filter and eventually to breakage. Conventional hydro cyclone filters available do not identify the grinding and rubbing of the inner body parts of the filter. The structure of the said filters is narrow which further does not facilitate the placement of inner body part with higher thickness and also do not provide mechanism that identifies leakage in condition of grinding and rubbing of the inner body parts. Further the structure of the conventional hydro cyclone filters is such that it completely seals the main body of the filter and therefore do not facilitate replacement of the inner body parts of the filter ultimately resulting into changing the entire hydro cyclone filter. Said hydro cyclone filters are narrow in size and therefore there is no gap (G) provided between the main body of the filter and the inner body parts of the filter as shown in fig 7. Due to said arrangement the inner body parts of the filter are more prone to grinding and rubbing and further there is no space provided for the leakage through which the damaged or worn out condition of the filter is identified; and the need arises to completely replace the entire filter. Farmers not being able to replace the entire hydro cyclone filter every now and then, after wearing out of the filter, tend not to use the hydro cyclone filter and alternatively switches up to other filters such as strainer type filter or avoids using any filters. Also the conventional hydro cyclone filters are made up of metal and therefore are highly prone to corrosion. Corrosion further decrease the shelf life and stability of the hydro cyclone filter. Further Failure of the filter causes the need to replace the filter which further requires extra cost of installing new filters and other equipments. The government provides subsidy to the farmers for period of 10 years. The same field would not get subsidy on irrigation equipment before 10 years. Therefore the cost of all the equipment will pound on Farmer. Therefore they are not economical and efficient. Alternatively farmers uses Strainer Type Filter. It is used to filter out the small dust particles mixed with water. Due to supplying water straight to Strainer type filter, it gets choked up very fast because of large and heavy sand particles in the water, therefore Strainer Type Filter's efficiency reduces and thus less amount of water is supplied further to the drip lines.

PRIOR ART AND ITS DISADVANTAGES: · US patent application US 4793925 A relates to a hydro cyclone device having complementary upper vortex finder and lower cone units each made of hard polyurethane together with a resilient, flexible, replaceable, polyurethane liner having a positive sealing flange associated therewith. The sealing flange of the liner complements with and engages with complementary sealing surfaces on the vortex finder and the lower cone unit when they are joined together by respective threaded portions. Thus, only three elements make up the basic hydro cyclone device with greatly improved resistance to leakage thereof. An outlet opening at the bottom end of the lower cone unit can also be provided with an adjusting unit and a wear insert therewith. However the prior art does not identifies the grinding and rubbing of the component parts of the hydro cyclone filter as it fails to provide mechanism that identifies leakage. Further the said filter is completely sealed and therefore it fails to replace the worn out components parts of the hydro cyclone filter and need arises to completely replace the hydro cyclone filter which is not economical and cost effective. It also does not provide increased shelf life of the hydro cyclone filter. It fails to identify the grinding and rubbing of the hydro cyclone filter as it does not facilitate the placement of inner body part with higher thickness. Further the said prior art provides the narrow design of the hydro cyclone filter; narrow design of the hydro cyclone filter further leads to early grinding and rubbing of the hydro cyclone filter and therefore decreases the shelf life of the filter. Also said filter is not corrosion resistant.

Another US patent application US 4956090 A relates to the invention relates to those hydro cyclones, which, for instance due to their length, do not lend themselves to manufacture in a single piece but are divided up into sections, which until now have been connected to one another usually with the help of flanged joints. In accordance with the invention it is proposed that the sections (52, 58, 60, 62) of a cyclone (50) be executed in such a way that the end of a section (e.g. 58) fits internally into the following section (60) in the direction of the flow and projects for a small distance into it, with the joint being sealed, if necessary, by a gasket. The sections are held securely together by a previously disclosed eccentric lock (70) of the folding strap type, at least two of which are arranged at each joint. Cyclones constructed in accordance with the invention can be imparted with curved form in order to facilitate, for example, their arrangement in batteries, and in those cases in which permanently connected cyclones are preferred, the sections can be welded together without the risk of crack formation, thanks to the fact that the arrangement in accordance with the invention produces fillet joints between the sections.

However, said prior art relates to connection of the upper and lower vertex component parts of hydro cyclone filters. It do not provide hydro cyclone filter with improved gasket. They fail to identify the grinding and rubbing of the component parts of the hydro cyclone filter, and thus are not efficient. Further the said filter is completely sealed and therefore it fails to replace the worn out components parts of the hydro cyclone filter and need arises to completely replace the hydro cyclone filter which is not economical and cost effective. It fails to identify the grinding and rubbing of the hydro cyclone filter as it does not facilitate the placement of inner body part with higher thickness. Also it does not increases the shelf life of the hydro cyclone filter. Furthermore said filter is not corrosion resistant.

DISADVANTAGES OF PRIOR ART: The existing prior art suffers from all or at least any of the following disadvantages; 1. None of them provides an improved hydro cyclone filter that facilitates the placement of gasket with higher thickness.

2. They fail to provide mechanism that identifies the leakage and thereby fails to identify the worn out condition of the inner body parts of the filter through leakage.

3. None of them identifies the grinding and rubbing of the component parts of the hydro cyclone filter.

4. Most of the prior art hydro cyclone filters are narrow due to which there is no gap between the main body and the inner body parts that ultimately leads to early grinding and rubbing of the component parts and thus are not efficient.

5. None of them increases the shelf life of the hydro cyclone filter

6. They fail to identify any leakage in the hydro cyclone filter as they are unable to detect grinding of the component parts and thus are not efficient.

7. Most of them requires to entirely replace the hydro cyclone filter which is very costly and the process of installing the same is cumbersome and thus they are not user friendly and cost effective.

8. None of them provides the hydro cyclone filter with replaceable component parts.

9. They fail to provide corrosion resistant and stable hydro cyclone filter.

Thus, in order to obviate the problems of the prior art and to provide the effective solution in the field of irrigation there is utmost need to come up with the invention that obviates the problems of prior art. OBJECTS OF INVENTION:

Said Inlet flange (1) is attached to the inlet chamber (2) and is provided to establish the connections with the inlet water pipelines in the present invention (P). Said inlet chamber (2) facilitates the flow of water inside the filter and thus create the cyclonic flow which flows down towards the gasket (7). Said inlet chamber is attached to the upper body (5) of the present invention (P). Said Outlet Flange (3) is attached to the upper body (5) and it facilitates the outlet flow (4) of water from the present invention (P). The upper body (5) is attached to the main body (6) and facilitates the first start of cyclonic motion of the water inside the filter. Said main body (6) is attached to the upper body (5) at one end and at the other end is attached to the outlet chamber (8) as shown in Fig.1. The water inside the filter continues the cyclonic motion initiated at the upper body (5) inside the main body (6) and continues the cyclonic motion until the water reaches the bottom part of the main body (6). Further the bottom part of the main body (6) of the present invention is increased in diameter in the range of 55-60mm to 1 10- 1 15mm more specifically 1 10 mm diameter to accommodate the gasket (7) of higher thickness as shown in fig 6 Said improved filter provides the gap (G) between the main body (6) and gasket (7) which further facilitates leakage in the damaged or worn out condition of the said gasket (7) . Said gasket (7) is attached beneath the main Body (6). Further in the gap (G) between the said main body (6) and the gasket (7) outlet chambers (8) are provided The Gap (G) is provided on the Bottom part of the Gasket and the Main body to identify the leakage of water when the gasket (7) is worn out or damaged. The water; in case of any grinding and rubbing of the present invention (P) leaks out of the said outlet chambers (8) and indicates the damaged condition of the gasket (7). This facilitates to identify any grinding and rubbing in the gasket (7) and worn out condition of the gasket (7) and thus facilitates in replacing only the worn gasket (7) instead of replacing the entire filter as contrary to the conventional hydro cyclone filters. Present invention (P) thereby provides increased shelf life to the hydro cyclone filter. The gasket (7) of the filter is prone to maximum grinding, rubbing and wear and tear. The hydro cyclone force generated inside the main body (6) leads to the collision of the dust, pebbles, and sand particles in the water and thereby leads to the rubbing and grinding, wear and tear of the gasket (7) and decrease the shelf life of the filter. Conventional hydro cyclone filters fails to facilitate the placement of the gasket in the filters and they also fail to identify the damaged condition of the gasket (7). This leads to the replacement of the entire hydro cyclone filter which is not feasible and economical for farmers.

Said flush tank (9) is provided for the sedimentation of the dust, sand particles after completion of all the cyclonic movement in the main body (6). Said flush Tank (9) is covered with the Flush Tank Cover (15), and is connected by the clamping mechanisms (1 1). Wherein said clamping mechanisms includes all the standard clamps available. The O-ring (10) is provided inside the flush tank (9) in order to prevent the leakage in the normal condition.
