Multi-cyclone collector

摘要

A multi-cyclone collector includes a suction port for sucking an air flow including contaminating particles, a cyclone accommodation chamber allowing the air flow sucked through the suction port to be guided thereinto, a plurality of cyclones each accommodated in the cyclone accommodation chamber, for transforming the air flow taken in to a downward swirl flow, separating the contaminating particles, then reversing the swirl flow to the upward swirl flow and releasing the upward swirl flow as a purified air flow, a cyclone exit chamber provided above the cyclone accommodation chamber, that allows the purified air flow from the cyclones to be guided thereinto, and a drain discharge chamber provided below the cyclone accommodation chamber, for collecting the contaminating particles separated by the cyclones.

1. A multi-cyclone collector comprising:
a suction port for sucking an air flow including contaminating particles; a cyclone accommodation chamber allowing the air flow sucked through the suction port to be guided thereinto; a plurality of cyclones each accommodated in the cyclone accommodation chamber, for transforming the air flow taken in to a downward swirl flow, separating the contaminating particles, then reversing the swirl flow to the upward swirl flow and releasing the upward swirl flow as a purified air flow; a cyclone exit chamber provided above the cyclone accommodation chamber, that allows the purified air flow from the cyclones to be guided thereinto; and a drain discharge chamber provided below the cyclone accommodation chamber, for collecting the contaminating particles separated by the cyclones, wherein each of the cyclones has a swirling portion allowing the downward swirl flow to travel therethrough, a reversing portion for reversing the swirl flow to the upward swirl flow, and a discharge pipe for guiding the contaminating particles separated from the air flow into the drain discharge chamber, the discharge pipe has a lower opening sealed by liquid stored in the drain discharge chamber, the multi-cyclone collector further comprises a liquid level control means for controlling liquid level of the liquid so that the liquid in the discharge pipe does not reach the reversing portion, and the liquid level control means is a communication pipe connecting the cyclone exit chamber and the drain discharge chamber.
