<p>PURPOSE:To enable washing of a filter within a short time with a small-sized and light-weighted device by disposing in an exhaust pipe a washing air nozzle for blowing the air from an air tank into a dust collector through an electromagnetic valve in the reversed direction to the flow of the exhaust gas. CONSTITUTION:In a filter washing device 10, a washing air nozzle 11 is disposed on the way of an exhaust pipe 31 connected to the outlet 35 of the casing 33 of a muffler 32, and its injection port is directed to the exhaust outlet of a dust collector. An air tank 12 installed to the casing 33 through an adiabatic plate 19 has the inlet 15 connected to an air compressor and the outlet 16 connected to the washing air nozzle 11. An electromagnetic valve 13 is disposed in a pipeline 17. As the air tank 12 is disposed near the washing air nozzle 11 in this way, the pipeline 17 is shortened and thinned. The electromagnetic valve 13 is also miniaturized, and the compressed air having high discharge and flow speed can be blown into the dust collector in the reversed direction.</p> |
