Title of Invention

A CEMENT TUBEWELL FILTER SLOTS

Abstract A R.C.C. tube well slot filter comprising a pipe having slots through out its length, the lower end having a socket and the upper end of the pipe Hiving a ring on the outer periphery for receiving the socket of the other slot filter by a rubber ring.
Full Text Field of the invention
The present invention relates to cement tubewell filter slots. Background
In earlier days, the water supply from under the surface of the earth was through G.I slot filter or PVC filter slots. As time passed by the technology and information brought new aspects to replace these G.I slot filters or PVC filters slots. This led to the invention of cement tubewell filters slots, which have longer life and are less expensive. The cement tubewell filters slots are unique in their design as compared to the traditionally manufactured G.I filter slots, PVC filters slots or cemented pipes.
Object of the invention
The present invention relates to cement tubewell filter slots, which are manufactured with the conventional reinforced cement, water and cresher (stone dust) having evenly distributed steel wire reinforcement as well as a method for manufacturing the same on an industrial scale. These said filters are commonly known as cement tubewell slot filters. The reinforced cement, water and cresher (stone dust) is homogeneously distributed and arranged with the help of steel wires, which have extremely small diameter. This provides high mechanical strength to the filter slots.
Summary of the invention:
The present invention relates to a cement tubewell filter slots comprising a pipe having slots throughout its length, the lower end having a socket and the upper end of the pipe having a ring on the outer periphery for receiving the socket of the other filter slots by a rubber ring.
The earth has different layers of soil. It consists of loose earth loam earth sandy earth hard clay and even at places the stone clay where PVC filter slots and filters made of other materials failed to fulfill purpose of irrigation because the cement tubewell filter slots loose their strength and becomes brittle as soon as they are lowered under the earth surface.
The material used in the cement tubewell filter slot and other filters is not only concrete but also made up of cresher (stone sand). The space between the particles of measure is much less than the space, which exists in the filters slots, made of concrete material. The cement tubewell filters slots are much more compact and does not allow the water to peculate from the wall.
The cement tube well filter slots are made up of the material as stated above. The bore of the filter slots is very smooth and a ring is formed on the outer surface of the slot filter, which fits in the socket of another slot filter with the help of a rubber ring. This assembly is then tightened to keep it in a straight position permanently. The wall of the filter slots is made from fine rich material reinforced with steel wire vertically and spherically. The fineness of the material used in the manufacture of cement tubewell filter slots leaves no space for water and air to pass through. Consequently, steel wires arranged in the cement tubewell filters slots have a longer durability. The rusted iron and steel wire found in PVC slot filter and other slot filters get cracks due to the pressure.
The slot on these filters is a oblong slot which does not get blocked and allows the water to seep in the filters slots for a longer period of time.

Detailed description of the accompanying drawings
Fig. 1 and Fig. 2 shows the bore of the filter slots where a ring on the outer surface of the slot filter is provided. The slot filters of oblong shape evenly distributed through out the line of the slot filter pipe.




We claim:
1. A cement tube well filter slots comprising:
a pipe having slots throughout its length, the lower end having a socket and the upper end of the pipe having a ring on the outer periphery for receiving the socket of the other filter slots by a rubber ring.
2. A cement tube well filter slots as claimed in claim 1 wherein the filter
slots is made up of cement and stone dust reinforced with steel wires.
3. A cement tube well filter slots as claimed in claim 1 wherein the slots
are oblong.
4. A cement tube well filter slots substantially as herein described with
reference to the accompanying drawings.
