PURPOSE: A rubber-plug apparatus for hopper sealing is provided to prevent contaminated water generated in the washing of an electric dust collector to be inserted into an auxiliary hopper. CONSTITUTION: A body part (210) is positioned between a main hopper and an auxiliary hopper which are a dust collection reservoir for collecting dust. A hose part (230) is formed of a pipe which injects gas into the body part or discharges the gas. A gas valve part (250) controls injecting or discharging the gas. An outer cover blocking film (211) prevents the dust which is collected in the main hopper to be inserted into the auxiliary hopper. An inner frame (213) maintains a primary shape of the body part. An upper plate part (213a) is connected to the upper side of the body part. A lower plate part (213b) is connected to the lower side of the body while maintaining a predetermined distance with the upper plate part. A supporting part (213 c) is positioned between the upper plate part and the lower plate part and supports it. A handle part (215) is protruded from an upper end of the body part and transports the body part. |
