Description

[0001] MODULAR CYCLONIC SEPARATOR FOR SEPARATING SOLID IMPURITIES FROM AN AIRFLOW [0002]

The present invention relates to a cyclonic separator, and more particularly to a modular cyclone separator for separating solid impurities from an air stream.

Fig. 1 shows a conventional centrifugal filter 1 used for separating solid impurities such as dust, debris, solid particles and the like from an air stream using the cyclone principle. The conventional centrifugal filter 1 includes two separation barrels 11 and 12, three pipes 131, 132 and 133, an exhaust fan 14 and a solids collector 15. Each of the separation barrels 11 and 12 has air inlets 111 and 121 and air outlets 112 and 122 and solids outlets 113 and 123 facing each other along the central axis. The pipe 131 is connected to the air inlet 111 of the separation barrel 11. The pipe 132 interconnects the air outlet 112 of the separation barrel 11 and the air inlet 121 of the separation barrel 12. The pipe 133 interconnects the air outlet 122 of the separation barrel 12 and the exhaust fan 14. The solids collector 15 is connected to the solids outlets 113 and 123. The exhaust fan 14 sucks the outside air through the pipe 111, the separation barrel 11, the pipe 132, the separation barrel 12 and the pipe 133, Is operable to follow the cyclone flow pattern to separate a portion of the solid impurities from the air stream. The separated solid impurities fall through the solids outlets 113, 123 into the solids collector 15.

In this configuration, the pipe 132 interconnecting the separation barrels 11, 12 needs to have a length sufficient to bend in a manner that does not affect the flow of airflow through the pipe 132. Therefore, the pipe 132 occupies a relatively large space. In addition, when one or more additional separation barrels are used to enhance the filtration effect, one or more additional pipes, such as pipe 132, may be required to provide a series connection of additional separation barrels (s) between the separation barrels 11, do. In this case, due to the use of additional pipe (s) and separation barrel (s), the overall volume of the conventional centrifugal filter 1 becomes much larger and pipe entanglement may occur.

The airflow in the separation tube flows out of the first filtration module through the second fluid passage in one three-port valve. The separated solid impurities can be discharged to the outside of the first filtration module through the outlet end of the outer tube body.

For the second filtration module, the airflow passes through the first fluid passageway in one of the two three-port valves connected to the inlet end before entering the separation tube.
