Description

Compressed Air Purifier {Pneumatic filter}

The present invention relates to a compressed air purifying apparatus, and more particularly, to remove the foreign substances such as dust, oil, water, and the like contained in the compressed air supplied to the pneumatic equipment. It is about.

Generally, compressed air refers to air compressed by an air compressor, and such compressed air is used in various pneumatic equipment such as prime movers, air brakes, air hammers, and drills.

However, such compressed air contains foreign matters such as dust, oil, moisture, etc. from the air compressor in the process of compressing and supplying air, and these foreign matters are the biggest cause of failure of the pneumatic equipment. That is, foreign matter such as dust contained in the compressed air is caught in the coupling part and the operating part of the pneumatic equipment, causing errors in the operation of the pneumatic equipment, causing a malfunction, and moisture contained in the compressed air is inside the air passage of the pneumatic equipment. Corrosion results in shortening the life of pneumatic equipment.

In consideration of this, a general pneumatic device is generally used to purify foreign matters contained in compressed air by an absorber or a filter, but a commonly used filter cannot completely remove fine foreign matters contained in compressed air. In addition, a filter such as an element used in an automobile has a problem in that the filter itself needs to be replaced after a certain period of time because it is difficult to reuse accumulated foreign matter.

The present invention has been made to solve the problems described above, more specifically, compressed air is completely filtered twice to supply to the pneumatic equipment, as well as the compression configured to wash and reuse the filter The purpose is to provide an air purifier.

In order to achieve the above object, the compressed air purifying apparatus according to the present invention is installed on a pneumatic line of an air compressor and a pneumatic apparatus, and the compressed air purifying apparatus removes foreign substances contained in the air. The inflow passage and the discharge passage have an upper body formed in communication with the installation space portion therein, and detachably installed in the upper body, and have a foreign matter storage space for collecting foreign matter therein. The lower body having a valve for discharging a predetermined amount of foreign matter in the lower center, a supporting plate having a predetermined thickness connected between the upper main body and the lower main body, and fixedly mounted on the supporting plate to allow air to flow from the compressed air inflow passage. After separating the foreign matter contained in, it consists of foreign matter separation means for discharging through the compressed air discharge passage.

However, the production of the porous membrane 66 is not limited to this, and powders such as aluminum may be produced by condensation and sintering.

The centrifugal separator 64 is fixedly installed on the rotating shaft 12 installed through the shaft support hole 56 of the upper assembly 50 and passes compressed air discharged along the discharge hole 58 of the upper assembly 50. By separating the foreign matter while being divided into the upper disk (64a) and the lower disk (64b) having a predetermined interval from each other. The upper disc 64a has a shape inclined upward in the cross section toward the center, the lower disc 64b has a flat cross section, and the lower disc 64b is ejected from the discharge hole 58 of the upper assembly 50. A plurality of inlet holes (64c) are formed so that the compressed air is introduced.

In addition, a second porous membrane 68 is installed on the inner surface of the installation space portion 10b of the upper body 10 to collect foreign substances of compressed air discharged from the centrifugal separation member 64, and the porous membrane 68 ) Is also manufactured by folding a stainless steel mesh of the same material as the first porous membrane 66 several times in a zigzag manner, separated from the installation space (10b) is configured to be washed.

The operation of the compressed air purifying apparatus of the present invention having such a configuration will be described.

Referring to FIG. 2, the compressed air supplied from the air compressor 1 is quickly transferred to the space 54 of the upper assembly 50 to rotate the blowing fan 60 while rotating the high speed. At this time, the compressed air containing the foreign matter hits the first porous membrane 66 provided on the inner circumferential surface of the space portion 54, foreign matter having a predetermined size particles are collected in the porous membrane 66, the collected foreign matter is hard The photograph is collected into the foreign matter storage space 22 while sliding downward through the foreign matter discharge passage 46. The remaining compressed air is discharged through the discharge hole 58.

The compressed air transferred through the discharge hole 58 is introduced into the centrifuge member 64 through the inlet hole 64c formed in the lower disc 64b of the centrifuge member 64, and the centrifugal separator 64 is The inflow air is rotated at a high speed by the speed at which the rotating shaft 12 rotates. When the compressed air is rotated as described above, foreign substances that are heavier than pure compressed air have a greater amount of motion than pure compressed air, thereby generating a force to be separated from each other, and by this phenomenon, the upper disc 64a of the centrifugal separating member 64. Compressed air exiting at an interval between the lower disk 64b and the pure compressed air and the foreign matter is separated, the pure compressed air is raised and the foreign matter is captured while hitting the second porous membrane 68. That is, the pure compressed air is conveyed upwards and is conveyed to the pneumatic device 3 through the compressed air discharge passage 10c, and the foreign matter combined while colliding with the second porous membrane 68 forms large particles after a certain time. The weight falls freely downward along the gaps 42 and 52 between the inner diameter of the upper body 10 and the upper assembly 50 and the lower support 40 by the weight thereof.

The foreign matter falling freely accumulates in the foreign matter storage space 22 formed in the lower body 20, and when the amount of accumulation reaches a predetermined amount, the valve 26 detects the foreign matter outlet 24. Open. Then, the foreign matter is discharged to the outside by sliding along the mirror surface formed on the bottom of the foreign matter storage space 22 by the air pressure.

Meanwhile, the first and second porous membranes 66 and 68 can be separated and washed, and are used semi-permanently.

As described above, the present invention is that the compressed air supplied to the pneumatic equipment is purely compressed to remove the foreign matter by completely filtering the foreign matter through the first porous membrane and the second porous membrane while the compressed air supplied from the air compressor is transported Only air is transferred to implement a smooth operation of the pneumatic equipment, there is an effect that can significantly reduce the occurrence rate of the pneumatic equipment failure by the efficient removal of foreign matter.
