Abstract: A filtration tank (10) with a central vertical axis x comprises: a first chamber (54), a second chamber (56) and at least one filter element (66). The first chamber has a first inlet (20) through which fluid to be filtered enters the tank and is designed so as to provide a swirling flow of the fluid to the second chamber. The second chamber (56) has a second inlet (60), in fluid communication with the first chamber (54), and an outlet (20) through which filtered fluid exits the tank, the outlet (2.0) being preferably disposed lower than the second inlet (60). The filter element {66) may be disposed in the second chamber and may have a portion capable of free undulation due to movement of the fluid in which it is disposed caused at least in part by the swirling of fluid entering the second chamber. The swirling may be obtained by centrifugal forces induced within the tank at least in a portion of a fluid flow path preceding the second inlet. The tank may be used in a filtration system including a fixed head pressure column and a pipe system for providing fluid to the tank and the column. The fixed head pressure column has a top portion open to the atmosphere, and is mounted on and in fluid communication with the pipe system, for eliminating the suction of dirt into the pipe system.
Abstract translation: 具有中心垂直轴线x的过滤箱(10)包括:第一室(54),第二室(56)和至少一个过滤元件(66)。 第一室具有第一入口(20),待过滤的流体通过该入口进入罐,并被设计成提供流体到第二室的旋流。 所述第二腔室(56)具有与所述第一腔室(54)流体连通的第二入口(60)以及过滤流体通过所述出口(20)离开所述罐的出口,所述出口(2.0)优选地设置为低于 第二入口(60)。 过滤元件(66)可以设置在第二室中,并且可以具有能够由于流体的移动而自由起伏的部分,在该部分中,其被设置的流体至少部分地由进入第二室的流体的旋转引起。 旋转可以通过至少在第二入口之前的流体流动路径的一部分中在罐内感应的离心力来获得。 罐可以用于包括固定头压力塔和用于向罐和塔提供流体的管道系统的过滤系统中。 固定头压力塔具有通向大气的顶部,并且安装在管道系统上并与管道系统流体连通,以消除污物吸入管道系统中。

Abstract: A rotary sprinkler (10) comprises a body and a rotor (16). The body has an inlet bore (20), an outlet bore (38), and an internal cavity (70) therebetween. The inlet bore has an upstream end connectable to a water supply pipe and a downstream end formed as a jet nozzle. The outlet bore has an upstream end with a rim (42). The rotor has an axially extending shaft with an axial shaft channel and at least one vane with a vane channel extending away from the shaft and having an outlet constituting an outlet of the sprinkler. The shaft channel and the vane channel define a smooth water flow passage having an open cross-section. The shaft is inserted in the outlet bore of the body to enable free rotation of the rotor. The sprinkler further comprises a retaining ring (18) that is assembled to the upstream end of the shaft of the rotor, is disposed in the internal cavity of the sprinkler body, and is adapted to abut the rim of the outlet bore, thereby carrying axial forces applied to the rotor.
