Description of drawings
In order to be illustrated more clearly in technological scheme of the present invention, the below will do to introduce simply to the accompanying drawing of required use among the embodiment, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic representation of the gas compressor that provides of the embodiment of the invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technological scheme in the embodiment of the invention is clearly and completely described.
As shown in Figure 1, a kind of gas compressor that the embodiment of the invention provides comprises the casing 1 of both ends open, and an end of casing 1 and the first end cap 2 are tightly connected, and the other end of casing 1 and the second end cap 3 are tightly connected;
Be equipped with a rotating shaft 4 that is positioned at casing on described the first end cap 2 and the second end cap 3, be installed with clutch shaft bearing 41 on the first end cap 2, be installed with the second bearing 42 on the second end cap 3, the two ends of rotating shaft 4 respectively with clutch shaft bearing 41 be connected bearing 42 and be connected, thereby the purpose that the two ends of realizing rotating shaft 4 are rotationally connected with the first end cap 2 and the second end cap 3 respectively;
Be installed with a rotor 5 in the described rotating shaft 4, offer the shock tube 6 of at least one axial setting along rotating shaft 4 on the rotor 5, shock tube 6 along the circumferential direction is evenly distributed on the rotor 5, and particularly, the quantity of shock tube 6 is 1 ~ 100;
Offer pressurized gas inlet 21 and the minimal pressure gas outlet 22 that can communicate with shock tube 6 on described the first end cap 2, pressurized gas inlet 21 is used for pressurized gas are accelerated to the velocity of sound or ultrasound velocity;
Offer compressed rear pressurized gas outlet 31 and the compressed front low-pressure gas entrance 32 that can communicate with shock tube 6 on described the second end cap 3;
The outer periphery of described rotor 5 are installed with blade 7, offer on the casing 1 with blade 7 over against the propellant entrance 11 that arranges and propellant outlet 12.
The specific works principle of gas compressor provided by the invention is as follows:
(1) the incident stage: propellant enters in the casing 1 from the gas access 11 that drives casing 1, propellant promotes blade 7 and rotates, blade 7 rotor drivens 5 rotate together, and after rotor 5 rotated, pressurized gas accelerated by pressurized gas inlet 21, spray into successively in the oscillator tube 6 on the rotor 5 with the velocity of sound or supersonic speed, wherein, propellant can be the sub-fraction of pressurized gas shunting, also can be other source of the gas, in addition, the rotation of rotor 4 also can drive by equipment such as motors;
(2) compression stage: the pressurized gas that are accelerated by pressurized gas inlet 21 are to the compressed front low-pressure gas compressed action in the shock tube 6, because spraying into the gas of shock tube 6 from pressurized gas inlet 21 is velocities of sound or supersonic, so can produce shock wave when pressurized gas spray into when shock tube 6 runs into the compressed front low-pressure gas that has existed in the shock tube 6, compressed front low-pressure gas in the pressurized gas that shock wave sprays into just as an invisible piston cuts off and the shock tube 6, and the compressed front low-pressure gas in the shock tube 6 compressed, the temperature and pressure of the compressed front low-pressure gas in the shock tube 6 is all raise, then discharge by compressed rear pressurized gas outlet 31; The pressurized gas that spray into from pressurized gas inlet 21 simultaneously are because to shock tube 6 interior compressed front low-pressure gases actings, self-energy is consumed, and stays in the oscillator tube 6 so become minimal pressure gas;
(3) compressed front low-pressure gas injects the stage: stay the minimal pressure gas in the shock tube 6, rotation along with rotor 4, can be communicated with minimal pressure gas outlet 22 and compressed front low-pressure gas entrance 32, compressed front low-pressure gas enters in the shock tube 6 by compressed front low-pressure gas entrance 32, minimal pressure gas in the shock tube 6 is ejected, minimal pressure gas is discharged by minimal pressure gas outlet 22, and compressed front low-pressure gas is stayed in the shock tube 6; Rotation along with rotor 5, shock tube 6 is communicated with pressurized gas inlet 21 and compressed rear pressurized gas outlet 31, the compressed front low-pressure gas of staying in the shock tube 6 is compressed by the pressurized gas from pressurized gas inlet 21 incidents again, enters next circulation, and so forth circulation.
In sum, adopt the to-and-fro motion of piston to come directly gas to be compressed different from prior art, gas compressor of the present invention adopts pressurized gas that low-pressure gas is compressed, and realizes the purpose of pressurized gas, and compression efficiency significantly improves.Wherein, the composition of pressurized gas and low-pressure gas can be identical, also can be different.
Further, also be provided with two sealing plugs 8 between described casing 1 and the rotor 5, the outlet 12 of propellant entrance 11 and propellant is between two sealing plugs 8, and sealing plug 8 is used for isolated high-voltage gas, propellant and compressed gas, guarantees the normal operation of system.
In addition, the present invention adopts propellant to enter in the casing 1 from propellant entrance 11, propellant promotes blade 7 and rotates, blade 7 rotor drivens 5 rotate together, therefore, rotating shaft 4 of the present invention need not stretch out that casing 1 is outer to be connected with motor and to be rotated by motor driving, the sealability of casing 1 significantly improves, and has greatly reduced the amount of leakage of the interior pressurized gas of casing 1.Simultaneously, be connected with motor because rotating shaft 4 of the present invention need not be stretched out outside the casing 1, therefore, reduced the volume of whole air wave refrigerating device, convenient transportation, installation and operation.
The above is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also are considered as protection scope of the present invention.
