摘要： This unit includes a two-piece, cylindrical canister partitioned intermediate ends into upper and lower chambers connected by a hole in the center of the partition. A filter cartridge in the upper chamber has an axial bore closed at its lower end and connected at its upper end to the inlet of a vacuum motor, which is mounted on the upper end of the canister. A dust inlet in the lower chamber is connected to a nipple or duct which is inclined transverse to the canister axis and a line radially thereof. When the motor is operated smoke and spatter sparks enter the lower chamber nearly tangentially and are swirled therein so that heavy particles and sparks are flung by centrifugal forces against the chamber wall and drop harmlessly to the canister bottom. Lighter particles rise to the upper chamber and are filtered out by the cartridge as the air passes radially therethrough to the vacuum motor.

摘要： A cleaning system for a filter unit used in connection with a plurality of independently operable welding guns in which the suction chamber surrounding the tip of each gun is connected via sections of flexible hose and a flap valve to a main dust collecting pipe or manifold to which the inlet duct of the filter unit is attached. A source of suction is connected to the outlet duct of the filter unit so as to draw objectionable smoke and fumes that are generated in the area of the welds through the filter unit. This filter comprises a cylindrical housing containing a conventional radial-fin filter cartridge. A plurality of straps are fastened to a shaft, that is journaled in the upper end of the housing for rotation from the exterior thereof, either manually or by a motor. The straps extend downwardly into the space between the housing and the cartridge. Each strap carries on its outer surface a flexible wiper, which engages the inside of the housing, and on its inner surface a plurality of vertically-spaced, flexible tabs, which project into the spaces between adjacent pleats in the cartridge. To clean the cartridge, the shaft is rotated so that the tabs knock the caked dust from the cartridge pleats as they pass or flex thereover, at the same time that the flexible wipers sweep dust from the inside surface of the housing.
