919,470. Filters. BERLINE J. R. A. July 25, 1961 [July 27, 1960], No. 26925/61. Class 46. In a cluster of filtering tubes each tube 1 has a flared upper end supported by an annular rubber or plastic gasket 18 in a supporting plate 16 and is held under adjustable pressure from bolts 21 in washers 20 which, through tube retaining rings 19, exert pressure against a plurality of tubes simultaneously. Each tube consists of a core 2 of perforated sheet metal or expanded metal and a sheath 5 of metal or synethetic fabric e.g. " Terylene " Registered Trade Mark and is rigidly united with an endpiece 4 which is secured to a metal lattice 6 by a stud 8. For cleaning, filtrate accumulated in a dome of the filter housing is counterstreamed by the pressure of gas in the dome, or introduced thereto, and this with the help of the resultant vibration of the tubes, causes the filter cake on the outer face of the filter fabric to be removed. Alternatively, steam under pressure may be used to clean the tubes. The washers may be circular or star-shaped, each point of a star being assigned to a tube.

A. 1961年7月25日[1960年7月27日],第26925/61号。 46级。在一组过滤管中,每个管1的喇叭形上端均由环形橡胶或塑料垫圈18支撑在支撑板16中,并由垫圈20中的螺栓21在可调压力下保持,垫圈通过管固定环19固定在垫圈20中,同时向多个管施加压力。每根管子都由穿孔金属板或金属网芯2和金属或合成纤维织物(例如尼龙)的护套5组成。 “涤纶”注册商标,并与通过螺栓8固定到金属网格6的端头4牢固地结合在一起。为了清洁,积聚在过滤器外壳穹顶中的滤液被穹顶中的气体压力逆流,或引入其中,并借助于管子的最终振动,使滤布外表面上的滤饼被去除。或者,可使用加压蒸汽清洁管道。垫圈可以是圆形或星形的,星形的每个点都分配给一个管。
