Abstract
Provided is a technology for preventing leakage of mist through a gap in a mist collector. A mist collector configured to collect mist generated in processing of a workpiece includes: a rotary filter configured to catch the mist; a drive unit configured to drive the rotary filter in such a manner as to rotate about a rotation axis passing through the center of the rotary filter; and a housing including a tubular portion. The housing houses the rotary filter in the tubular portion. A radial direction of the rotary filter is orthogonal to an inner surface of the tubular portion. An inflow preventing mechanism configured to prevent the mist from flowing into a gap between the tubular portion and the rotary filter is provided in housing.

A mist collector configured to collect mist generated in processing of a workpiece, the mist collector comprising:
- a rotary filter configured to catch the mist;
- a drive unit configured to drive the rotary filter in such a manner as to rotate about a rotation axis passing through the center of the rotary filter;
- and
- a housing including a tubular portion,
- wherein the housing houses the rotary filter in the tubular portion, and a radial direction of the rotary filter is orthogonal to an inner surface of the tubular portion,
- an inflow preventing mechanism configured to prevent the mist from flowing into a gap between the tubular portion and the rotary filter is provided in the housing,
- the inflow preventing mechanism includes a preventive wall having a cylindrical shape, and
- the preventive wall having the cylindrical shape is disposed in such a manner that a central axis of the preventive wall coincides with a central axis of the tubular portion and the preventive wall is upstream of the rotary filter in the direction of a flow of air passing through the rotary filter.
A mist collector configured to collect mist generated in processing of a workpiece, the mist collector comprising:
- a rotary filter configured to catch the mist;
- a drive unit configured to drive the rotary filter in such a manner as to rotate about a rotation axis passing through the center of the rotary filter;
- and
- a housing including a tubular portion,
- wherein the housing houses the rotary filter in the tubular portion, and a radial direction of the rotary filter is orthogonal to an inner surface of the tubular portion,
- an inflow preventing mechanism configured to prevent the mist from flowing into a gap between the tubular portion and the rotary filter is provided in the housing,
- the inflow preventing mechanism includes an annular section provided on the inner surface of the tubular portion in such a manner as to face the gap, and
- the annular section is downstream of the rotary filter in the direction of a flow of air passing through the rotary filter, and
- an inner radius of the annular section in the radial direction is shorter than an outer radius of the rotary filter in the radial direction,
- wherein the rotary filter includes:
- an edge section;
- and
- a filter section fixed to the edge section, and
- the inner radius of the annular section in the radial direction is shorter than an outer radius of the edge section in the radial direction.
