The self-cleaning filter apparatus of claim 6, wherein the exhaust flange is externally connected with a purging mechanism for inputting cleaning gas from the exhaust passage to the outside of the air inlet along the opposite path of the gas transmission, for performing a powder blowing operation on the internal chamber.
8. The self-cleaning filter device of claim 1, wherein the housing member and the scraper member are stainless steel, titanium, copper, aluminum plastic, teflon, or nylon; and the shell part, the scraping part and the filtering part are coated with a coating on one side contacted with the coating gas, and the coating is fluorine dragon, titanium nitride or tungsten carbide.
9. The self-cleaning filter apparatus of claim 1, further comprising a temperature control member for temperature regulating the housing member to provide a suitable temperature to the interior chamber.
