<p>The present invention relates to a device for preventing dust accumulation at a dust collecting chamber, wherein slip boards to drastically reduce landing resistance of dust are installed individually at a bottom part, edge parts and corner parts of a dust collecting chamber to inhibit the settling or accumulating of dusts, thereby preventing a decrease in the efficiency of dust collection. The device of the present invention comprises: a dust collecting chamber (4) consisting of a bottom (9), walls (4a) and a roof (4b); multiple vent holes (11) formed on the bottom (9) to have the filter fabric (13); reversed V-shaped slip boards (34) installed on the bottom (9) around the vent holes (11); a reversed V-shaped slip board (35) installed on the bottom (9) between the two slip boards (34); a plate-shaped slip board (36) connecting the walls (4a) and the bottom (9); and a slip board (37) vertically installed at the corner (29) part formed by connecting the two walls (4a) and the bottom (9), and the walls (4a), wherein the device may further comprise: a vertical surface (34a) formed at both side parts of the slip board (34) to be tightly attached to the wall (4a); an inclined surface (35a) formed at both side parts of the slip board (35) to get narrower when going downward to be tightly attached to the slip board (34); and a curved surface (36a) formed at both side parts of the slip board (36) to be tightly attached to a curved surface (37a) of the slip board (37).</p> |
