Abstract: A method and apparatus for filtering particulates from a turbid liquid is provided. The apparatus is preferably used to filter particulates from water used to flush a pipeline after a cleaning operation, after hydrostatic testing or during product displacement at a high flow rate. The apparatus includes an inlet valve for receiving the turbid liquid from a liquid source connected to a gas buster for discharging the turbid liquid and air into a break tank located beneath the gas buster. A self-cleaning portable liquid filter having an inlet is connected to an outlet of the break tank and includes a screen filter for receiving the turbid liquid from the break tank. Particulates from the turbid water are accumulated on an internal surface of the screen filter and clean water is discharged from the filter through a discharge port. A flush mechanism is provided to rinse the accumulated particulate cake from the surface of the screen filter upon actuation of an automatic rinse cycle. A sludge tank is located below the filter and flush mechanism for capturing a flush liquid and the particulates. A centrifugal pump driven flush line having a first end connected to the sludge tank and a second end connected to the break tank is provided for recirculating the flush liquid and accumulated particulates from the sludge tank to the break tank to be re-filtered. The turbid liquid is received from the pipeline through the inlet valve and discharged through the gas buster into the break tank. Where a plurality of break tanks are provided, the fluid levels are equalized. The turbid liquid is then pumped from the break tank to the self-cleaning portable liquid filter and a clean liquid is discharged from the outlet thereof An automatic rinse cycle is engaged upon actuation of a signal triggered by sensing of a predetermined pressure differential across an inlet and an outlet of the screen filter.

Abstract: A cartridge-filter cleaning spinner comprises a handheld spindle rod that can accommodate a variety of filter sizes. The spindle rod has two inward pointing slip-ring hand-tightened hubs. A cartridge filter is loaded on the spindle rod by removing one of the slip-ring hand-tightened hubs, slipping the cartridge filter onto the spindle snug against the other slip-ring hand-tightened hub, and then reinstalling the first slip-ring hand-tightened hub on the spindle rod. The cartridge filter is then free to spin around while the spindle rod handles themselves remain stationary. A water jet from a garden hose is then directed at one end of the cartridge filter to one side so the cartridge filter begins spinning. The water jet is then worked down slowly to the opposite end while keeping the spinning action going. The process is then repeated, but with the water jet directed to the other side so the cartridge filter spins in the opposite direction. This helps both sides of the longitudinal outside pleats of the cartridge filter material to come clean. The cleaning is accomplished by centrifugal action and does not involve backwashing.

Abstract: A fluid filtering system including two filter units so arranged in parallel that flow of fluid from a source to a point of usage can take place by way of only one unit at a time. Means is provided which can sense the degree of contamination of whichever one of the units is in service so that when the degree of contamination is such that the said one unit is no longer in a suitable condition for further filtering service, that means causes the by-passing of that unit and the bringing of the other unit into service. The system further includes back-flushing means which is automatically operable upon a filter unit when so by-passed for cleaning that unit. Timing means is also provided for automatically controlling the period of time during which back-flushing operation is permitted to continue.

Abstract: A self-cleaning filter and vortexer is provided in which a filter rotates over the clean fluid outlet port of a vortexer cannister in the direction of the flow of fluid into the tangential inlet port of the vortexer. The peripheral velocity of a freely rotating filter will approximate the flow velocity of the fluid into the tangential inlet port to enhance the centrifugal acceleration effect of the vortexer and the dynamic cleaning of the filter medium. This acceleration enhances centrifugal separation of the heavier particulates in the vortexer and enhances the dynamic cleaning of the fines and other particulates from the filter medium. The drive mechanism for rotating the filter may be designed to be uneven so as to shake the filter medium as it rotates. The flow of fluid will pass thru the filter medium and be exhausted as a cleaned fluid into the outlet port of the vortexer cannister. Throughout this disclosure centrifugal refers only to the normal acceleration associated with curvilinear motion while dynamic refers to all three components of relative curvilinear motion, namely, normal, Corolis and tangential. The vortexer (cyclone) herein referenced to utilizes the centrifugal component only while the rotating filter elements herein referred to are so designed as to utilize all three of the relative curvilinear components, hence the distinction throughout between centrifugal and dynamic effects.

Abstract translation: 提供了一种自清洁过滤器和涡流器，其中过滤器沿着流体流入涡流器的切向入口的方向在涡流罐的清洁流体出口端口上旋转。 自由旋转的过滤器的圆周速度将近似流体进入切向入口的流速，以增强涡流器的离心加速效应和过滤介质的动态清洁。 这种加速增强了涡流器中较重颗粒的离心分离，并增强了过滤介质对细粒和其他颗粒的动态清洗。 用于旋转过滤器的驱动机构可以设计成不均匀，以便在过滤介质旋转时摇动过滤介质。 流体流动将通过过滤介质，并作为清洁的流体排放到涡流罐的出口。 在整个本文中，离心仅指与曲线运动相关的正常加速度，而动态是指相对曲线运动的所有三个分量，即正常的科波利斯和切线。 这里提及的旋流器（旋风分离器）仅在本文所述的旋转过滤器元件被设计成利用所有三个相对曲线部件时利用离心分量，因此在离心和动态效应之间的区分。
