Description

Aerial apparatus for lifting liquids, such as water, from mine wells to artesian wells, made in the form of a cylindrical chamber equipped with suction and discharge valves, are known. Air in the chamber in such devices is supplied through an automatic air valve to the upper part of the chamber.

A disadvantage of the known air vehicles of this type is that when the chamber is filled with water, there is considerable resistance to the movement of the air displaced from the chamber.

The proposed air unit is free from this drawback. The dryness of the invention lies in the fact that a U-shaped tube is located in the chamber of the apparatus, one end of which is brought into the pressure pipe, and the other is located in the upper part of the chamber.

In order to reduce the working pressure of compressed air for lifting liquid, the pressure pipe is connected to the air supply pipe by a calibrated channel.

The drawing shows a diagram of the installation for lifting fluid with an air apparatus.

The installation consists of an air unit / for lifting fluid;

standpipe / bin; air valve ///; Receiver IV and Compressor V.

Air device / for lifting liquid is produced in the form of a cylindrical chamber /, suction valve 2 and pressure pipe 5 with pressure valve 4. In the chamber / there is a U-shaped air tube 5. One end of this tube with a conical tip enters the pressure pipe 3 , and the second end is located in the upper part of the chamber near the upper bottom; the rounded portion of the tube is located above the discharge valve 4. A tube 6 for supplying compressed air is introduced into the cylindrical chamber through the upper bottom. The air is compressed by the air compressor V and is fed to the receiver IV, from which it is automatically activated through its air valve /// into the air tube 6.

The air valve / I serves to periodically intake air from the receiver into the apparatus chamber and to prevent air leakage from the receiver during the period when the chamber is filled with water. The valve /// is designed according to the principle of a conventional safety spring or cargo valve, acting on the difference in air pressure and load 7 on the diaphragm 8,

actuating rod 9 with nostril valve at end.

The operation of the air vehicle is as follows. The cylindrical chamber / sinks below the level of liquid (water) in the source (a shaft well or an artesian well) and is filled completely with water. As air is pumped by the manual compressor V into the receiver (U), the valve /// operates at a definite pressure and the compressed air enters through the tube 6 into the chamber /. By the pressure of compressed air, the water from the chamber / is displaced by the pressure pipe J into the water / U column.

Simultaneously with a decrease in the water level in the chamber / the water level in the right branch of the tube 5 decreases. As soon as the water level in the right branch of tube 5 reaches the bent part, the air from the last branch will penetrate into the left part of the tube, from where it will go to the supporting pipe 3 and lifting up, water as an air ejector. As the air leaks through the tube 5 into the pressure pipe 3, the pressure of the water column mixed with air to valve 4 decreases sharply and the water rises as an emulsion on the principle of airlift, as in the pipe 3 it is balanced by the air pressure in the cylindrical chamber. The water from the pump will be forced out until the level reaches the lower edge 1 of the outlet opening of the discharge valve 4 and the excess air from the chamber follows behind the water / and throws the air emulsion out of the pipe 3 into the tank of the COLUMN.

By .vtepe, the air pressure in the chamber / valve /// closes and blocks the access of compressed air to the tube 6. When water is lifted from the chamber / and from pipe 3 into the tank of the water dispenser II, and the access of compressed air to the chamber / is stopped - the cavity of the pump of the latter is again filled with water. The air in the chamber at the same time / without a hitch will escape through the U-shaped tube through pipe 3 into the atmosphere and will not prevent the filling of the chamber / water. As soon as the water level in the chamber reaches the edge of the right branch of the U-shaped tube, the latter will be filled with water and block the air from the chamber} into the atmosphere, which will increase the pressure in the chamber. At the next intake of compressed air into the chamber, the cycle will be repeated.

In order to reduce the working pressure of compressed air for lifting the liquid, the pressure pipe and the entry point of the horse into it. The U-shaped tube is connected to the air supply tube f by a calibrated tube W. Thanks to this device i; the pressure pipe 3 will form a one-oz emulsion. The rise of emulsion in the form of an emulsion requires a significantly lower working pressure.

The proposed air pump for lifting liquid works cyclically, supplying water intermittently and making maximum use of the energy of compressed air for useful work; thereby increasing the efficiency of the installation with such an apparatus.
