摘要： A stationary cylindrical drum type filter with self-cleaning capability and suitable for use as a cell or module in a bank of like filter units. A helically wound rod defines a cylindrical shape over which a foraminous web is supported in tubular configuration to form a filter element. A suction nozzle is disposed inside the filter element closely adjacent thereto and drive means causes the nozzle to rotate and traverse the filter element between and guided by the adjacent coils of the helix, and controls cause the spiral motion of the nozzle to reverse upon reaching each end of the filter element, and to start and stop in response to predetermined pressure drops through the filter. A plate closes off the filter element at one end of the helical support, and a mounting plate at the other end surrounds the inlet opening thereat and is square shaped with flanges at the side edges for abutment proximate like filter units to form a composite filter bank of any desirable shape and size, with all inlets in a common plane. The individual filter units may have a common suction source and common drive means including gears and removable sectional shaft elements to facilitate removal or addition of the filter units, or they may have individual drives and suction sources.

摘要： An internal loading cylindrical air filter apparatus having a circular tubular knit pile fabric filter element extending unsupported between end plates to provide an essentially full length unobstructed filter area, and having a rotating internal suction cleaning nozzle therefor. The tubular filter element is supported at its entry end by a detachable angle ring having a cylindrical ring flange extending through an opening in the entry end plate of the apparatus to permit endwise assembly and disassembly of the fabric filter element into the apparatus. Annular or helical strands may extend in circumferential engagement with the filter element for restraining it from ballooning out of effective cleaning distance with respect to the rotating suction nozzle under heavy filtering conditions, and a crank may be provided for adjusting the extending length of a helically extending restraining strand for controlling the degree of restaint imposed on the filter element.
摘要翻译：一种内装圆柱形空气过滤装置，其具有在端板之间不支撑的圆形管状针织绒头织物过滤器元件，以提供基本上全长的无障碍过滤面积，并具有旋转的内部抽吸清洁喷嘴。管状过滤器元件在其入口端处由可拆卸的角环支撑，该环形环具有延伸穿过设备入口端板中的开口的圆柱形环凸缘，以允许将织物过滤元件端接地装配和拆卸到设备中。环形或螺旋线可以与过滤元件周向接合延伸，用于限制其在重的过滤条件下相对于旋转吸嘴在有效的清洁距离之外膨胀，并且可提供曲柄以调节螺旋形延伸的延伸长度用于控制施加在过滤元件上的静止程度的约束线。
