摘要： A method of cleaning an screen in a manufacturing process step that employs a chamber including a drain line having a screen configured and disposed in the chamber above the drain line to trap soluble materials includes detecting a build-up of soluble material on the screen, ceasing a work operation in the chamber, and initiating a screen cleaning operation. The screen cleaning operation includes closing a computer operated valve fluidly connected to the drain line to fluidly isolate a portion of the chamber, automatically introducing an amount of solvent into the chamber once the computer operated valve is closed with the amount of solvent filling the chamber and/or the drain line to fully immerse the screen, and opening the operated valve after a predetermined amount of time to empty the chamber and the drain line of solvent once the soluble materials trapped on the screen are dissolved.

摘要： The disclosed self-cleaning filtration system and self-cleaning filter solves various problems by replacing a standard filter cartridge with an adapter screwed in place of the cartridge, a filter of limited size with a motor for rotating an inlet cover plate and an outlet cover plate over a body with a plurality of longitudinal channels inside of a circumferential filtration media where the different parts of the media are used alternately in forward and backward flow. As the cover plates rotate, each longitudinal channel comes in successive fluidic communication with either an entry opening where oil is pushed in the longitudinal channel through the filtration media and into an external cavity where filtered oil is reintroduced in the engine, or the longitudinal channel comes in fluidic communication with a drain opening where the flow through the filtration media is reversed and oil from the external cavity is pushed back into the longitudinal channel to transport stored debris into a decanter for storage, elimination, decantation and reuse. In another embodiment, instead of entry and drain openings, the oil is placed directly in contact with each longitudinal channel with the exception of the channel in fluidic communication with the drain opening. The self-filtration system includes a self-cleaning filter used in tandem with an adapter, a decanter, and a series of hoses.

摘要： A method for steam backwashing a filter assembly. The filter assembly has a housing for receiving contaminated liquid and discharging filtered liquid, a filter positioned within the housing for filtering the contaminated liquid, and a drain coupled with the housing. Steam is sent through the housing to remove contaminants from the filter without draining the contaminated liquid or the filtered liquid from the housing. The steam forces the contaminated liquid, the filtered liquid and the contaminants through the drain.
