Abstract

The cyclone separation device has a case (1), a space partition plate (7), and a cylindrical member (11). The case (1) is formed into a cylindrical shape and has a first intake port (4), an outflow port (6), and a second intake port (5). The first intake port (4) has a circumferential opening (2) circumferentially formed in a side surface on a side of the one end of the case (1), and a fixed blade (3) arranged along the circumferential opening (2). The outflow port (6) is disposed on a surface on the side of the one end and discharges the swirling airflow fed through the first intake port (4). The second intake port (5) is disposed on a side surface on a side of the other end opposite to the one end.

First claim

The invention claimed is:

1. A cyclone separation device comprising:
a cylindrical case including:
a first intake port further including:
a circumferential opening circumferentially formed in a side surface on a side of a one end of the cylindrical case; and
a fixed blade arranged along the circumferential opening and generating a swirling airflow to separate foreign matters contained in an airflow;

an outflow port that is disposed on a surface on the side of the one end and discharges an airflow having a swirling component fed through the first intake port; and
a second intake port that is disposed on a side surface on a side of the other end opposite to the one end so as to be located at the lowermost part of the cylindrical case in a state where a central axis of the cylindrical case is kept in a horizontal position;

a space partition plate that partitions an interior of the cylindrical case into a first swirl chamber on an inner-circumference side and a second swirl chamber on an outer-circumference side and has a through-hole for providing communication between the first swirl chamber and the second swirl chamber; and
a cylindrical member disposed in the first swirl chamber on the side of the other end of the cylindrical case such that a central axis of the cylindrical member agrees with the central axis of the cylindrical case,
wherein, the cylindrical member is disposed such that an end face of the cylindrical member on the side of the outflow port is located within a range of the through-hole in the direction of the central axis.

2. The cyclone separation device according to claim 1 , wherein,
the cylindrical member including:
a supporting member disposed on the central axis of the cylindrical member on the side of the outflow port of the cylindrical member and
an arc blade having a bend that is bent into an arc shape and is disposed between the supporting member and a peripheral end of the cylindrical member;

a direction of the bend from the peripheral end of the cylindrical member toward the supporting member is the same as a rotating direction of a swirling airflow generated by the fixed blade; and
the arc blade is located between the cylindrical member and the outflow port, and at least two in number of the arc blade are radially arranged around the supporting member.

3. The cyclone separation device according to claim 2 , wherein the supporting member is a conical member whose bottom face has a size the same as the end face of the cylindrical member, and a top of the conical member is located on the side of the outflow port.
