DEVICE FOR AUTOMATICALLY REMOVING DUST ACCUMULATED INSIDE DUST COLLECTING PIPE

摘要

PURPOSE: A device for automatically removing dust accumulated inside dust collecting pipe is provided to increase dust collecting efficiency of dust collecting apparatus by smoothly removing dust accumulated on bent part of the dust collecting pipe and easily install the device and perform repairing by simplifying structure of the device. CONSTITUTION: In a dust collecting pipe(10) of dust collecting apparatus equipped with inlet for collecting dust and connected to suction fan of the dust collecting apparatus, wherein the dust collecting pipe(10) is formed as a circulation dust collecting pipe for circulating flow of air according to driving of the suction fan, the device(1) for automatically removing dust accumulated inside the dust collecting pipe comprises a pipe open-and-shut means(30) installed on a suction fan connecting part(18) of the circulation dust collecting pipe(10); an accumulated dust removing means(50) inserted into the circulation dust collecting pipe(10) and moved inside the dust collecting pipe(10) along air sucked in when opening the pipe open-and-shut means(30) so that the accumulated dust removing means(50) removes dust accumulated on an inner part of the dust collecting pipe(10); and an open-and-shut plate adjusting means(70) installed at one side of the pipe open-and-shut means(30) so that the pipe open-and-shut means(30) closes the pipe when the accumulated dust removing means(50) is closely adhered to the inner part of the circulation dust collecting pipe(10), wherein guiding members are installed at the circulation dust collecting pipe(10) to guide the accumulated dust removing means(50) in such a way that the accumulated dust removing means(50) is smoothly circulated in the pipe.
