Abstract

PURPOSE:To efficiently separate powder dust produced in metal machining by automatically washing a filter which collects powder dust with water and recovering the washed out powder dust. CONSTITUTION:A metal oxide powder collector is composed of a sucking part 10, a filtering part 20, and a discharging part 30. Shower nozzles 4 sandwiching the filters 3 from the upside and the downside are set inside of the filtering part 20. The dust-contg. air is introduced into the sucking part 10 from outside the dust collecting tower 1, filtered by the filters 3, and becomes cleaned air which is moved to a stack 5 of the discharging part. Also, when sensors set in the filters 3 detect the filters are filled up, cleaning water is arranged to be sprayed from the shower nozzle to the surfaces of the filters 3. With the cleaning water, the powder dust flows down to a water tank in the lower part of the dust collecting tower 1 and it is recovered after precipitation.
