Description

technical field [0001] The invention relates to the technical field of filtering and cleaning, in particular to a filtering device and a filtering method. Background technique [0002] In the field of filtration and cleaning, filtration equipment is usually used for sewage filtration operations. The filtration equipment is equipped with a filter screen to filter out green algae, grease, floating matter or sludge in the sewage through the filter screen. After the filtration operation, there are impurities remaining on the filter screen, and water needs to be sprayed back and forth on the surface of the filter screen to take away the residual impurities through the water flow. At present, the power source of the reciprocating water spraying method is driven by a motor, and then the nozzle is driven to reciprocate through a chain drive. However, lubricating oil is required for chain lubrication. During the cleaning process, oil stains are easily mixed into the water flow, caus...
