专利汇可以提供Filtering apparatus专利检索，专利查询，专利分析的服务。并且A filtering apparatus adapted to be connected to a burner apparatus of the furnace type in buildings to remove fly ash, smoke and other contaminate particles from the flue gases or discharge gases therefrom. It includes three stages of filtration the first being a cyclone type separator and the second and third stages being mechanical filters. An exhaust or blower assembly is mounted on the casing to draw gases through the filtering apparatus from the chimney. Operation of the same is made automatic by a temperature sensor in the filtering apparatus which is connected to the chimney by means of transverse duct work. An air inlet is provided in the transverse duct work to draw in ambient air along with the gases for the purposes of cooling the same as they pass through the filtering apparatus.，下面是Filtering apparatus专利的具体信息内容。
1. A filtering device adapted to be connected to a chimney of a furnace type apparatus comprising, a casing, a cyclone type separator positioned in a base portion of the casing, said cyclone type separator being formed by a first cylindrical member positioned in the lower portion of the casing with a second smaller diameter cylindrical member positioned in said lower portion of the casing and concentric therewith with the smaller cylindrical member extending short of the length of the larger cylindrical member and with an air inlet pipe connected tangentially to the larger cylindrical member to direct airflow into the casing to the separator and with an outlet therefrom being connected to the inner cylindrical member, a pair of filter members positioned in said casing above the cyclone type separator with each filter member being separately removable from the casing for cleaning purposes with the filters being positioned at the outlet of the cyclone separator, an exhaust fan including a blower member connected to the casing and having an air inlet connected to an outlet of said casing beyond said filter members and said cyclone with an electric motor drivingly connected thereto for operating the same, said exhaust fan having an outlet remote from said casing, a temperature sensing switch and an electric circuit adapted to be connected to a source of electric power and through the switch to the electric motor of said blower member, said temperature sensing switch being responsive to the rise and fall of temperature within the casing above a predetermined temperature and operative to turn on and off respectively said electric motor to operate said exhaust fan above the predetermined temperature transition means connected to the casing at the inlet to the cyclone and adapted to be connected to a chimney, said transition means including a duct work having an air inlet passage therein with an adjustable louver to vary the size of the inlet air passage and the amount of atmospheric air outside of the duct work being drawn into the casing to cool the exhaust gases from said chimney, and including heat motor actuated dampers positioned in the transition means adjacent the chimney and operative to open the transition means with a rise in temperature of exhaust gases from the chimney above a predetermined temperature.
