FIELD OF THE INVENTION

[001] Embodiments of the present invention, generally relate to separating sold undissolved particles from water, and in particular relate to a system for separating sand/grit/other heavier particles from water coming from a hand pumps and submersible pumps.

BACKGROUND

[002] Hand pumps and submersible pumps are widely used by domestic users living in a society or township. Due to receding underground water levels, when a domestic user pumps water from the bore well using submersible pump or hand pumps, along with water, a lot of sand/grit and undissolved solid particles (such as metal particles, anthracite particles, granite particles, stone particles) comes.

[003] Conventionally, the user allows the water to flow down the drain while assuming that after few minutes of pumping water, amount of sand coming along with water will reduce. However, this does not happen in practice and it leads to wastage of lot of precious water. As water is a limited natural resource, it is essential to be saved from any wastage.

[004] Therefore, there is a need for a system that can separate sand/grit and other undissolved solid particles from water coming from the hand pumps and submersible pumps, and can also save water from wastage. SUMMARY

[0010] To facilitate understanding, like reference numerals have been used, where possible, to designate like elements common to the figures. DETAILED DESCRIPTION

[0011] As used throughout this application, the word "may" is used in a permissive sense (i.e., meaning having the potential to), rather than the mandatory sense (i.e., meaning must). Similarly, the words "include", "including", and "includes" mean including but not limited to.

[0012] The phrases "at least one", "one or more", and "and/or" are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions "at least one of A, B and C", "at least one of A, B, or C", "one or more of A, B, and C", "one or more of A, B, or C" and "A, B, and/or C" means A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B and C together.

[0013] The term "a" or "an" entity refers to one or more of that entity. As such, the terms "a" (or "an"), "one or more" and "at least one" can be used interchangeably herein. It is also to be noted that the terms "comprising", "including", and "having" can be used interchangeably.

[0014] The term "automatic" and variations thereof, as used herein, refers to any process or operation done without material human input when the process or operation is performed. However, a process or operation can be automatic, even though performance of the process or operation uses material or immaterial human input, if the input is received before performance of the process or operation. Human input is deemed to be material if such input influences how the process or operation will be performed. Human input that consents to the performance of the process or operation is not deemed to be "material".

[0015] FIG. 1 illustrates a schematic representation of a sand separator system 100 for separating sand from water coming from a hand pump and submersible pump. The sand water separator system 100 includes an inlet 102 that is configured to receive water from the hand pump/submersible. The inlet 102 is cylindrically shaped inlet. The sand water separator system 100 is positioned in a vertical direction with respect to the ground, as shown in the figure 1. In an embodiment, the water fetched from ground by the hand pump/submersible may include solid undissolved particles such as sand particles, grit particles, metal particles, anthracite particles, granite particles, stone particles and other similar particles which are heavier than water and also insoluble in water. The sand separator system 100 is configured to remove all such particles.

[0016] According to an embodiment of the present invention, the inlet 102 includes a tangential mouth to provide a tangential entry of the water/fluid inside the sand water separator system 100. The inlet 102 may be made of plastic, metal or any other suitable material thereof.

[0017] The sand water separator system 100 further includes a cylindrical section 104 having a top portion, side portion, and bottom portion. The side portion of the cylindrical section 104 is coupled with the inlet 102, as shown in the FIG. 1. In an embodiment, the cylindrical section 104 is configured to receive water coming from the inlet 102. The cylindrical section 104 may be made of plastic, metal or any other suitable material thereof.

[0018] The sand water separator system 100 further includes a conical section 106. The conical section 106 includes a top portion and a bottom portion. The diameter of the top portion of the conical section 106 is larger than the diameter of the bottom portion of the conical section 106. Further, the diameter of the top portion of the conical section 106 is equal to the diameter of the cylindrical section 104. The top portion of the conical section 106 is attached with the bottom portion of the cylindrical section 104. According to an embodiment of the present invention, the conical section 106 is configured to provide a sliding path to the solid undissolved particles and guide them to a collection drum 108). The conical section 106 may be made of plastic, metal or any other suitable material thereof.

[0019] The sand water separator system 100 further includes the collection drum 108 having a top portion and a bottom portion. In an embodiment, the collection drum 108 is cylindrical shaped and diameter of the collection drum 108 is same as diameter of the cylindrical section 102. In another embodiment, the shape of the collection drum 108 may be different. Further, the top portion of the collection drum 108 is coupled with the bottom portion of the conical section 106, as shown in FIG. 1. According to an embodiment of the present invention, the collection drum 108 is configured to collect the solid undissolved particles (i.e., sand, grit particles, metal particles, anthracite particles, granite particles, stone particles and other similar particles which are heavier than water and also insoluble in water). The collection drum 108 may be made of plastic, metal or any other suitable material thereof.

[0020] The sand water separator system 100 further includes an outlet 110. The outlet 110 is attached with the top portion of the cylindrical section 104. In an embodiment, the outlet 110 is configured to provide exit/outlet to the clean water (i.e., water without sand, grit particles, metal particles, anthracite particles, granite particles, stone particles and other similar particles which are heavier than water and also insoluble in water). The outlet 110 may be made of plastic, metal or any other suitable material thereof. [0021] The sand water separator system 100 further includes a flushing valve 112. The flushing valve 112 is attached to the bottom portion of the collection drum 108. According to an embodiment of the present invention, the flushing valve 112 is configured to flush out the sand collected inside the collection drum 108. In an embodiment, to clean the solid undissolved particles collected in the sand collection drum, the flushing valve 112 is opened while water is still being pumped through the system. This ensures that all the water flows only through the flushing valve (instead of outlet 110) and provides necessary force, hence making flushing of sand/grit/other similar particles quick and fully effective.

[0022] In operation, according to an embodiment of the present invention, due to tangential entry of fluid by the inlet 102, helical pattern of the water flow is established inside the cylindrical section 104. The water/fluid enters tangentially into the cylindrical section 104 and the flow of water descends rotating near walls of the cylindrical section 104. The flow of water continues to descend until it reaches end position of vortex, where axial velocity component of the flow reverses itself, thereby making the flow to ascend. In an embodiment, the ascension of flow proceeds near axis of the cyclone, thereby forming double vortex (i.e., inner vortex and outer vortex), as shown in the FIG. 2.

[0023] In an embodiment, the inner vortex leads outflow of clean water through the outlet 110. Further, those skilled in the art will appreciate that the vortex finder (i.e., outlet) may go into the cyclone body and may protect the inner vortex from the high inlet velocity to stabilize it. Further, according to an embodiment of the present invention, solid undissolved particles (for example, sand, grit particles, metal particles, anthracite particles, granite particles, stone particles and other similar particles) are denser than the water/fluid and hence have a high centrifugal force, which directs them to the walls of the cylindrical section 104 and the conical section 106. Hence, during the operation, the solid undissolved particles collide with the walls, lose momentum, and get disengaged from the flow, thereby collecting inside the collection drum. The separated solid undissolved particles (i.e., sand, grit particles, metal particles, anthracite particles, granite particles, stone particles and other similar particles) slide on the walls of the conical section 106, and are collected inside the collection drum 108.

[0024] Those skilled in the art will appreciate that once the solid undissolved particles are collected in the collection drum 108, they cannot flow back into the main stream as the water in the collection drum 108 is stagnant, i.e., it has almost zero velocity. The movement of water has so little velocity that it cannot move sand back into the main stream, therefore the solid undissolved particles being heavier than water keeps settling inside the collection drum 108.

[0025] Further, in an embodiment, the conical section 106 is integrated with the collection drum 108. Due to integrated sand collection drum 108, the length/height of the conical section 106 has been reduced drastically; as otherwise, the length of the conical section would have been large for the same flow rate. Further, the integration of the collection drum 108 with the conical section 106 also helps in achieving lower pressure drop. Further, by making collection drum 108 an integral part of the conical section 106, a very compact sand water separator is achieved.

[0026] The sand water separator system 100 provides many advantages. First, the sand water separator system facilitates separating the solid undissolved particles such as sand, grit particles, metal particles, anthracite particles, granite particles, stone particles and other similar particles from the water. Further, the sand water separator system 100 provides conserving water at a high efficiency as it does not waste water. Further, the sand water separator system 100 does not require any filter media, sieve, chemicals or any external power source. Further, the sand water separator system 100 is almost maintenance free as it does not require changing of any part. Furthermore, the sand water separator system 100 provides a very compact sand water separator.
