PURPOSE: An apparatus for removing dust accumulated on the inner surface of side wall of hopper is provided to easily remove dust accumulated on the inner wall of the hopper without damage of adjacent facility or hopper. CONSTITUTION: In a dust collecting facility for passing dust adhered to bag filter(10) through the side wall of hopper(20) by air pressure so that the dust is dropped to a lower side, the apparatus for removing dust accumulated on the inner surface of the side wall of hopper comprises a sliding part(100) comprising a holder(101) which is installed on an outer surface(30) of the side wall of the hopper, and in which a space is formed, at least two or more first permanent magnets(105) which are inserted into the space inside the holder, and at one end of which cylinder arm(107) is installed so that the first permanent magnets are slid on the outer surface of the side wall of the hopper by expansion and contraction of the cylinder arm, and on which opposite polarities are alternately arranged, and a cylinder(110) installed on the outer surface of the side wall of the hopper to expand and contract the cylinder arm; and a dust removing plate part(200) comprising second permanent magnets(205) installed on an inner surface(40) of the side wall of the hopper so that the second permanent magnets are oppositely directed to the first permanent magnets and moved in such a way that the second permanent magnets are closely adhered to or separated from the inner surface of the side wall of the hopper with being interlockingly connected to sliding of the first permanent magnets by magnetic force with the first permanent magnets, an operating rod one end of which is installed at the second permanent magnets and moved in front and rear sides of the side wall by penetrating the side wall of the hopper, and supports(215) which are installed on the outer surface of the side wall of the hopper, and into which the other end of the operating rod is inserted, wherein the hopper side wall contacted with the first permanent magnets is formed of a non-magnetic substance.
