PROBLEM TO BE SOLVED: To provide a filter cleaning device which can enhance cleaning accuracy of a filter and can prevent scattering of powder dust without using a dust collector having a large suction amount.SOLUTION: A filter cleaning device is provided with a filter hanging member 13a which hangs a cylindrical filter A rotatably from a ceiling 3a of a casing 3, and an air nozzle 32 which jets air to the filter while changing a jet direction by rotating a jet hole of the air. The filter cleaning device includes a dust collector 2 which is connected so as to communicate with a space in the casing 3 and discharges powder dust in the space to an external, a collected dust collecting part 5 which is arranged beneath the casing 3, a filter rotation mechanism which rotates the filter A, and an air nozzle movement mechanism which moves the air nozzle 32.SELECTED DRAWING: Figure 1 |
