The present invention relates to a compressor air filter for forming compressed air, and more specifically, to maximize the compression efficiency by cooling the high temperature compressed air through the vortex tube, malfunction of the differential pressure valve to discharge the compressed air to the outside It relates to a compressor air filter that can be safely disassembled by preventing the damage.

As is well known, the air filter separates the moisture and foreign matters from the compressed air supplied from the compressor, and the conventional air filter includes a technical configuration of Korean Utility Model Registration No. 169181, 'Air Compressor Filter'. Referring to 1, the air drawn into the inlet 1 is discharged through the body 2 to the outlet 3 and filtered, and the water is discharged by the trap 4 installed under the body 2. In one known method, a rotary oil tool 5 capable of rotating inlet air inside a filter, and a circumferential rotation in which air flow rotated by the rotary oil tool 5 enables traveling over a long distance. One or more first and second diaphragms 9 and 8 having an induction path and through holes 6 and 7 formed above the rotational path.

The above-described conventional air compressor filter rotates the incoming air with the rotary oil tool 5 and discharges the air through the first and second diaphragms 9 and 8 to the outlet.

However, the conventional air compressor filter has the following problems.

First, the compressed air discharged from the air compressor is a high temperature state, the conventional filter simply rotates the air to be introduced and discharged to the outlet (3) through the first, second diaphragm (9) (8), high temperature Since it is discharged without lowering the temperature of the compressed air to form a state, there was a problem that the compression efficiency of the compressed air is not good.

Second, the compressed air supplied from the air compressor contains foreign substances and moisture such as soot, harmful gas, dust, bacteria, and the like, and the conventional filter is discharged without filtering the foreign substances and moisture, so that the compressed air using compressed air There is a problem such as causing trouble of the equipment, shortening the life and deteriorating precision and durability.

Third, in the conventional filter, water and foreign substances are discharged to the trap 4, and the trap 4 is equipped with a differential pressure valve (not shown) to discharge the pressure in the trap 4, and the differential pressure valve is moisture and foreign matter. As this gathering is mounted on the lower part of the trap 4, water and foreign substances are accumulated and frequently lead to malfunction of the differential pressure valve, and malfunction of the differential pressure valve is caused by a pressure difference when the trap 4 is removed for maintenance. There was a problem that occurred.

The present invention has been devised to solve the conventional problems as described above, it is possible to maximize the compression efficiency by cooling the high-temperature compressed air through the vortex tube, to prevent the malfunction of the differential pressure valve to discharge the compressed air to the outside To provide a compressor air filter that can be safely disassembled.

An inlet 11 is formed at one upper portion of the chamber 10 to suck high temperature compressed air supplied from a compressor (not shown), and an outlet 12 is formed at the other side to discharge compressed air from which water and foreign matter are separated. do. In addition, a drain hole 14 is formed in the lower portion of the chamber 10 so as to be connected to the flow path 13 to drain moisture and foreign matter separated from the compressed air, and the drain hole 14 includes a trap (nipple N). T) is connected and filled with moisture and foreign matter drained into the drain hole 14.

In addition, a differential pressure valve 15 is mounted on one lower side of the chamber 10 to control the discharge of compressed air in the trap 10 connected to the chamber 10 and the flow path 13 of the chamber 10. As shown in FIG. 3, the differential pressure valve 15 includes a valve housing 16 provided with a valve seat 16a to be connected to the flow path 13 of the chamber 10, and a valve of the valve housing 16. A sliding valve 17 is slidably coupled along the seat 16a and intermittently opens and closes the valve seat 16a, and a coil spring 18 elastically supporting the sliding valve 17.

Accordingly, when the sliding valve 17 supported by the coil spring 18 to close the valve seat 16a is pressed, the valve seat 16a is opened and the compressed air in the chamber 10 and the trap T is discharged to the outside. do.

The differential pressure valve 15 configured as described above is inclined in the chamber 10, and foreign substances separated from the compressed air slide into the trap T while being slipped.

The vortex tube 20 cools high-temperature compressed air sucked from the inlet 11 of the chamber 10 and discharges it to the flow path 13. The vortex tube 20 is shown in FIGS. 3 to 4b. Likewise, it is composed of a tube 21, a vortex injection port 22 and a warmth control valve 23.

The tube 21 guides the cold air outlet 21a for discharging the cooled compressed air to the flow path 13, the hot air outlet 21b for discharging the warm air separated from the compressed air, and the cold / hot air of the compressed air. It consists of the guide chamber 21c.

At the outer circumference of the vortex injection port 22, guide ring grooves 22a are formed to guide the compressed air sucked into the suction port 11, as shown in Figs. 4A and 4B, and the compressed air guided to the guide ring grooves 22a. A plurality of vortex jetting grooves 22b are formed in the vortex jetting port 22 so as to spray the to the inner wall surface of the guide chamber 21c.

The warmth control valve 23 regulates the discharge of warmth discharged to the warmth outlet 21b. The warmth control valve 23 is perforated with a valve hole 24a so as to communicate with the warmth outlet 21b. The valve knob 24 is screwed to the inner diameter of the outer end of the (21b), and the adjustment knob 25 is formed with a discharge hole (25a) to control the opening and closing of the valve hole (24a) while being screwed to the valve casing (24) It includes.

The vortex tube 20 constituting such a configuration is widely known as a conventional air cooling device that is used by the George George of France in 1928 using the hydrodynamic principle and applied to the entire industry. As shown in FIG. 5, hot compressed air sucked into the inlet 11 of the chamber 10 is vortex injected through the guide annular groove 22b and the vortex jetting groove 22a of the vortex jetting port 22 as in 4b. Likewise it is put into the guide chamber 21c to rotate at high speed. The rotating air (primary vortex; a) is rapidly moved by the action of centrifugal force, so that the pressure and density are rapidly increased, and a large pressure difference is generated in the rotational air. 21b), and the remaining compressed air is returned to the other side and at the same time forms the secondary vortex (b) by the spindle 25b and then goes to the cold air outlet 21a, where the secondary vortex (b) The flow of is located at the center of the primary vortex (a) flow and passes through the region of lower pressure and expands and decelerates to generate cold air while losing heat.
That is, in the outer and inner two air flows (a, b) rotating at the same rotational direction and the same rotational angular velocity, the air particles of the secondary vortex (b) flowing through the center are the primary vortex (a) flowing through the outside. Since the time of one revolution with the air particles of is the same (same angular velocity), the actual speed of motion is lower than the outer flow. This difference in the kinetic speed means that the kinetic energy is reduced, so that the temperature of the secondary vortex (b) is reduced by this lost kinetic energy, so the lost kinetic energy is converted into heat and flows outward to the primary vortex (a). Increasing the air temperature of the secondary vortex (b) flowing inside is the principle that the temperature is further lowered.
