Abstract
PURPOSE: To prevent clogging of a dust for high-humidity dust-laden gas economically and efficiently by automatically starting or stopping water spraying to high- temp. materials according to the temperatures of the dust-laden gas and the duct wall surface.
CONSTITUTION: The rotary cylinder 3 of a knock-out machine 1 and a dust collector 8 are operated and the molds A having been charged with molten metal are fed into the cylinder 3 by a conveyor 15. The molds A are knocked out to castings and molding sand, and the high-temp. materials are cooled by the water spray. The dust-laden gas produced at this time is introduced into the device 8 through a duct 7, where it is purified and is then released into the atmosphere. In this case, when the temperatures of the dust-laden gas and the wall surface of the duct 7 detected with temp. detectors 10, 11 both exceed the set temp. above the dew point of the dust-laden gas, this is detected by a temp. controller 12, which in turn opens a control valve 14 so that water is sprayed from a water spraying pipe 13. When at least one of the devices 10, 11 lowers below the set temp., the valve 14 is closed to stop the spraying.
