MODULAR CYCLONIC SEPARATOR FOR SEPARATING SOLID IMPURITIES FROM AN AIRFLOW
First Claim
1. A modular cyclonic separator comprising:
- a plurality of separating tubes, each of which includes an outer tube body having opposite inlet and outlet ends and defining a separating chamber therein that is in spatial communication with said inlet and outlet ends, and an air-guiding impeller coaxially fixed in said inlet end of said outer tube body, and formed with an axial hole and a plurality of spiral channels that are disposed around said axial hole for causing an airflow, which flows radially into said separating chamber through said spiral channels, to follow a cyclonic flow pattern through said separating chamber and around a central axis of said outer tube body, such that some of solid impurities are separated from the airflow within said separating chamber; and
a plurality of three-port valves, each of which has first and second ports with the same size and a third port, and is configured with a first fluid passage in fluid communication with said first and third ports, and a second fluid passage in fluid communication with said second and third ports;
wherein each of said separating tubes is capable of connecting selectively with one of said three-port valves to form a first filtration module, in which said inlet end is connected detachably to said third port of said one of said three-port valves, or with two of said three-port valves to form a second filtration module, in which said inlet and outlet ends are connected detachably and respectively to said third ports of said two of said three-port valves;
wherein, for said first filtration module, the airflow passes through said first fluid passage in said one of said three-port valves prior to entering said separating tube, the airflow in said separating tube flowing out of said first filtration module through said second fluid passage in said one of said three-port valves, the separated solid impurities being able to be discharged out of said first filtration module through said outlet end of said outer tube body; and
wherein, for said second filtration module, the airflow passes through said first fluid passage in one of said two of said three-port valves that connects said inlet end prior to entering said separating tube, the airflow in said separating chamber flowing out of said second filtration module through said second fluid passages in said two of said three-port valves, the separated solid impurities being able to be discharged out of said second filtration module through said first fluid passage and said first port of the other one of said two of said three-port valves.

Abstract
A modular cyclonic separator comprises separating tubes each including an air-guiding impeller that is fixed coaxially in an outer tube body and that is formed with spiral channels for causing an airflow, which flows radially into the separating tube, to follow a cyclonic flow pattern through a separating chamber in the separating tube, thereby separating some of solid impurities from the airflow within the separating chamber. Each separating tube is capable of connecting selectively with one or two three-port valves to form a first or second filtration module, in which the airflow passes through a fluid passage in the one three-port valve or one of the two three-port valves prior to entering the separating tube.
