Apparatus and method for cleaning metal filter

An apparatus for cleaning a metal filter, the apparatus comprising:

• a cleaning bath having a predetermined size and connected to a cleaning solution tank;
• a jig which is vertically elevatable and horizontally slidable in the cleaning bath, the jig being configured to receive the metal filter fixed thereto;
• a nozzle assembly mounted so that a discharge hole thereof is faced upward in the cleaning bath, the nozzle assembly being configured to spray compressed air or water, which is supplied from the outside, into the cleaning bath;
• and
• a controller which is configured to control supply and blocking of a cleaning solution from the cleaning solution tank to the cleaning bath, supply and blocking of the compressed air or the water to the nozzle assembly, movement of the jig, and filling or discharging of the water into/from the cleaning bath,
• wherein, when the metal filter is mounted on the jig so that an opening of the metal filter is faced downward, the controller controls the movement of the jig so that the nozzles of the nozzle assembly sequentially enter the metal filter through the opening, and the controller selectively controls the supply and blocking of the water, the cleaning solution, and the compressed air, and the draining of the cleaning bath according to predetermined logic to sequentially perform cleaning and drying of the metal filter within the cleaning bath,
• wherein the nozzle assembly comprises an air nozzle configured to spray the compressed air and, a water nozzle installed spaced apart from the air nozzle and configured to spray the water, and
• wherein the jig is configured to move vertically and horizontally relative to the air nozzle and water nozzle to allow the air nozzle and water nozzle to selectively enter the opening of the metal filter.
