Description

  The present invention relates to a dust collector using a cylindrical filter used for collecting dust such as laser fume, printing powder, dust at the time of packing, general dust, etc., and in particular, a cylindrical shape by a simple operation from the outside of the dust collector. The present invention relates to a filter devised so that dust or the like collected on the outer peripheral surface can be peeled off and dropped by physically swinging the filter.

For dust collection such as laser fume, printing powder, bagging dust, general dust, etc., a turbo fan with excellent suction performance is used to suck the external air containing dust from the air intake into the housing. The external air is taken into the cylinder from the side surface of the mold filter, and dust is attached to the side surface of the cylinder filter to capture and remove the separated air from the exhaust port to the outside of the housing. Conventionally, a dust collector with a discharge method has been used.
For example, Patent Document 1 discloses a configuration of such a dust collector.

  In addition, the dust collector is supplied with compressed air into the cylinder of the cylindrical filter in order to prevent clogging of the cylindrical filter and enable operation for a long time. There is a dust collector equipped with an air cleaning device that blows off adhering dust to the outside and peels and drops it onto a lower collection tray.

That is, the swinging movement of the cylindrical filter F is executed by hitting the operation grip 57, and the dust D that has been forcibly attached to the side peripheral surface 17 of the cylindrical filter F and clogged is shaken off. Then, it is dropped on the lower collection tray 21 and collected. That is, by hitting the operation grip 57, the shift rod 55 is pushed in. The pushed shift rod 55 is returned by the spring 59, and this is repeated, whereby the cylindrical filter F is swung.

Then, according to the dust collector 1A according to the present embodiment configured as described above, the eye attaches to the side peripheral surface 17 of the cylindrical filter F by a simple operation of hitting the operation grip 57 from the outside of the housing 11. It is possible to effectively remove the dust D causing clogging.
