Description

The invention relates to the field of compressor engineering and relates to membrane compressors used in tanks with aerated liquid during the purification of water or other liquids from dissolved gases or dissolution of air and / or other gases in a liquid.

Compressors with a flat membrane in which a round flexible membrane is clamped around the perimeter between the lid and the cylinder are known in the art are driven in an oscillatory motion (for example, Altukhov SM Membrane Compressors. M .: Mashinostroenie, 1967, p. 81, fig. 57; SU 1638364 A1 of 03/30/91 Byul. No. 12).

The prototype of the claimed device is a membrane ball compressor consisting of a base, to which an elastic membrane ball is fixed along the perimeter, see DE 2702123, 07/27/1978

The disadvantage of the above-mentioned solutions is the complexity (and sometimes impossibility) of using structures in tanks with aerated liquid, as part of floating aeration systems.

The technical result of the claimed invention is to increase the buoyancy, compactness, specific performance and expansion of the scope of the compressor design.

The invention is illustrated by the following drawings.

in FIG. 1 schematically shows the proposed compressor, a longitudinal section;

on A), B) FIG. 2 shows options for attaching a spherical membrane to the base;

on A), B) FIG. 3 shows the claimed compressor in the extreme positions of the solenoid rod;

in FIG. 4 illustrates an example of the use of a ball compressor for purging a tank with water (Rozhnovsky towers).

The drawing shows schematically the proposed compressor, a longitudinal section, see FIG. one.

A membrane ball compressor consists of a base (1) to which an elastic membrane ball (2) is fixed around the perimeter, see. FIG. 1. Based on (1), the armature of the solenoid (3) with the movable stem (4) is stirred inside the elastic membrane-ball (2). From the outside, at least the following communications are brought to the base (1): a power cable (5), a supply connection (6) through the inlet valve (7), a discharge connection (8) through the exhaust valve (9).

Elastic membrane-ball (2) performs the function of the working body, and is also part of the housing of the claimed compressor.

The elastic ball membrane (2) can be made, for example, from ethylene-propylene rubbers.

The shape, size, material and tightness of the elastic membrane-ball (2) ensures the buoyancy and compactness of the design of the claimed invention.

The fastening of the elastic membrane-ball (2) to the base (1) is hermetic and is carried out with the help of a pressure ring, see A) FIG. 2, or is inserted with a tension into the groove, see B) FIG. 2

Membrane ball compressor works as follows.

From the power cable (5), the anchor of the solenoid (3) is actuated with a movable solenoid rod (4). When downward of the moving rod of the solenoid (4), gas (air) is drawn in from the external environment through the inlet (6). The extreme lower position of the solenoid rod (4) is presented in B) FIG. 3. Stroke limitation is governed by the height of the rod and the characteristics of the material / shape / size of the elastic membrane-ball (2). During the upward movement of the movable rod of the solenoid (4), the air is vented from the inner cavity by an elastic ball-membrane (2) through the discharge pipe (8). The extreme upper position of the solenoid rod (4) is shown in A) FIG. 3. Air inlet and outlet is regulated by inlet (7) and outlet (8) valves.

This principle of operation provides a high specific compressor capacity.

The method of use is to ensure the transfer of air and / or gas from the environment and / or at least one tank to the environment and / or at least one tank.

An example of the application of the claimed invention.

FIG. 4 shows a water tower (10) in which there is a floating aeration system on the surface of the water. The system uses a membrane ball compressor (12). The compressor (12) provides for the intake of air from the environment and then forcing air into the thickness of the liquid in the water tower through the aerator (11).

Comparative characteristics of the claimed device with the well-known are presented in table 1.

As can be seen from the table, the claimed device provides improved performance of the compressor with the same power, i.e. an increase in the efficiency of the compressor is achieved by reducing losses due to friction and energy dissipation of elastic forces as a result of conversion to thermal energy.
