Abstract

Water extractor. The aim of the invention is to extract the water that can be filtered in the holes of the quarries of aggregates due to rain, backwaters etc. Since the explosive (nagolite) that is normally used to load the holes is not compatible with water. The water extractor consists of two hoses, one inside another and a distributor powered by an air compressor. The distributor introduces vacuum and/or pressure to them alternately. The hoses are introduced to the bottom of the hole in contact with the water, they are emptied over them with the distributor, filling them a certain length of water, and then introducing air pressure, so that the valve of the outer hose closes, leaving the water through the inner hose, repeating the process until the hole is free of water.

Description

Water extractor

Technical sector

The invention falls within the field of aggregate quarries, and has been developed specifically for extract the water that by rain or backwater can be filtered in the holes that are drilled in quarry banks, making it difficult in this way the detonation of the explosive (nagolite) for not being this one compatible with water.

State of the art

Currently the methods used to facilitate this work have not experienced a special relevance. As a more primitive technique, the "blowing" is being used. it consists of introducing a hose from inside the hole 40 mm of approximately diameter and rigid consistency (for example polyethylene), so that once introduced until the deep and in contact with the water, it is passed by an intense pressurized air stream and as a result expels water contained at the bottom of the hole to the outside.

This procedure presents some difficulties, for example: it does not extract all of the water, the entire inner surface of the hole gets wet, the hose requires a firm grip, otherwise if there is a lot water in the hole can leave the hose pushed by the air outward abruptly, etc.

It is also being used for this work special electric or combustion engine pumps internal; it should be noted that due to its weight its handling, also having the difficulty of facilitating the network electric, if necessary, since the electrical installations are removed from the fronts of quarry.

Explanation

The objective of this invention is to extract the water that for various reasons can seep inside the rain holes, backwater, etc. These usually have a diameter ranging between 75 and 100 mm. and a length of 10 to 22 m. approximately, conditions under which the water extractor You have to remove it from the bottom of the holes. Proceed in principle in the same way as the first technique mentioned previously, that is, the extractor hose is introduced water inside the hole to the bottom of it, in contact with water (the hose must be of sufficient length for this) and through the manual system of which the water extractor proceeds to extract it in a more comfortable and safe due to the lower weight of the equipment and also to the lower pressure of air with respect to the techniques mentioned above.

The energy source necessary for the water extractor operation is compressed air that can Supply the same compressor of the drilling machine of the quarry by means of a hose.

Description of the drawings

Figure 1 shows a general view of the invention, which highlights each and every one of the elements that compose it.

It consists mainly of a distributor of compressed and / or empty air, two hoses (14) and (15) of different diameters arranged inside each other, with a valve of admission and retention of water (16) in solidarity with the lower end of the hose (14) of greater diameter.

Hoses (14) and (15) with diameters Approximately 40 and 30 mm. respectively, they are set to distributor via a quick connect type coupling Fireman (not drawn), the hose (14) at its lower end is fixed to the water intake and check valve (16) and the hose (15) is fixed to the fixing sleeve (18), which is in turn attached to the valve body (16) at its end upper, also the filter (17) is arranged in the part lower body of water intake and check valve (16) to prevent the entry of particles that may damage the mechanical operation of the system.

The air inlet valve (1) of 32 mm. (inch and quarter) opens or closes the air supply provided by the compressor for system operation by means of a suitable hose for said valve.

The three-way valve (2) can direct the compressed air flow in two different ducts alternatively and manually just by changing the crank of the three-way valve (2) from one position to the other, in one determined position, the flow of compressed air is directed to high speed through the air outlet duct (3) (40 mm. inside diameter) to outside, air speed tablet channeled through this duct produces a strong vacuum that accuses the water and vacuum outlet duct (5) (20 mm. inner diameter) for being concentrically arranged in the inside of this duct with the outlet in it direction, this vacuum is transmitted to the two hoses (14) and (15) simultaneously through the vacuum line (6), valve vacuum communication (7), pressure relief valve remnant (11) and through the compressed air inlet duct (4) to the hose (14). Communication of the vacuum with the hose (15) is transmitted directly through the outlet duct of water and / or vacuum (5).

Under these conditions the two hoses (14) and (15) are filled with water at a certain level through the filter (17) and water intake and retention valve (16), such and as detailed in figure 3, whose water level (22) in the inside of the hoses is above the water level (21) of the borehole, the amount of water that enters inside the themselves is a function of the suction force that occurs in the inside of the duct (5).

When changing the position of the crank of the two-way valve (2) the air flow is now conducted through the compressed air inlet duct (4) through the pressure regulator (12), which controls the pressure to a value determined, the flow of compressed air flowing through it conduit overcomes the resistance of the spring (10) closing the exhaust pressure relief valve (11), transmitting the compressed air flow to the outer hose (14) where it pushes to the water contained in both hoses (14) and (15) and forces it out through the water and vacuum outlet duct (5) to the outside. During this process the water intake and retention valve (16) is kept closed by the pressure exerted by the water preventing it from re-entering the hole; also the vacuum communication valve (7) that is closed and prevents air / water pressure from entering the valve escape of the remaining pressure (11), which in turn is maintained closed due to air pressure. The function of this valve is allow the change of pressures inside the hoses Be done in a short time.

The vacuum gauge (8) records the vacuum in the inside the hoses (14) and (15) and the pressure gauge (13) records the pressure of them.

Description of an embodiment

Figure 2 shows the first example of process of an embodiment, where you can see that they have introduced the hoses (14) and (15) through the hole to the bottom and in contact with water; at this time the intake valve and water retention (16) opens in contact with it allowing the filling the hoses through the filter (17) until balance the level (21), (22) of water contained in the borehole with  the one inside the hoses.

Figure 2 shows the second example of realization process, which consists of water aspiration, where it can be seen that the flow of compressed air is directed by the three-way valve (2) outwards through the duct air outlet (3), a strong vacuum in the water and vacuum outlet duct (5), which transmits it to the hoses (14) and (15) simultaneously through the conduit of vacuum (6), vacuum communication valve (7) following the exhaust pressure relief valve (11), which is maintained opened by the pressure exerted on it by the spring (10) and a through the compressed air inlet duct (4) to the hose (14); the hose (15) receives the vacuum directly by the water and vacuum outlet duct (5). As a consequence, the water contained in the borehole enters the hoses through the filter (17) and water intake and retention valve (16) so aspirated, thus achieving that the level (22) of water contained inside the hoses is well above the level (21) of the hole.

In figure 4 it is observed as the water that in the previous process had entered inside the hoses, is expelled outside, pushed by the air pressure that is now manually operated by operating from the crank valve  three way (2); so that the flow of compressed air goes to through the pressure regulator (12) which regulates the pressure adapted to the resistance of the hoses (3,5 Kg./cm^{2} approx.), this controlled pressure causes the valve to close escape of the remaining pressure (11) overcoming the resistance of the spring (10), so that the air pressure pushes down the entire water content of the hose (14); due, the water intake and check valve (16) is closed by the pressure exerted by the water on it, forcing it to go through of the fixing sleeve (18) and hose (15), outlet duct of water and vacuum (5) to the outside.

In this way the water contained in the borehole in issue is extracted to its full extent according to the process explained.

As for the screw (9), it allows to regulate the spring pressure (10) which in turn presses on the valve escape from the remaining pressure (11), to open it when the pressure inside the hoses drops below 1.5 Kg / cm2 approximately (this happens when changing the process of vacuum pressure when operating with the three-way valve) allowing escape more quickly all the remaining air contained in the hoses (14) and (15) through the communication valve of vacuum (7), vacuum duct (9) and water outlet duct and vacuum (5) to the outside, thus acting successively until all the water is extracted from the bottom of the hole.

With the vacuum gauge (8) you can control the vacuum recorded by hoses (14) and (15) during the process of suction, as with the pressure gauge (13) with which you can also see the pressure inside the hoses during the process of water expulsion.
