Abstract

The invention relates to a self-operated bidirectional time-staggered backwashing self-cleaning filter and a filtering backwashing method thereof. The filter comprises a tank body in which a circulating cavity is formed; a driving speed reducing mechanism is arranged at the bottom of the circulating cavity and corresponds to the oil inlet in position, and power for oil to enter drives the drivingspeed reducing mechanism to rotate; a fixing assembly is fixed in the circulating cavity, and two circles of filter element mounting holes which are arranged in a staggered manner and are correspondingly arranged up and down are formed in the top and the bottom of the fixing assembly; two circles of filtering elements are sequentially connected in the radial direction of the fixing assembly from inside to outside; the output end of the driving speed reducing mechanism drives the end part of a sewage suction assembly, the sewage suction assembly rotates in the fixing assembly, and two ends of the sewage suction assembly are respectively connected with suction nozzles which synchronously run with the sewage suction assembly and are communicated or blocked with the inner-ring or outer-ring filter element mounting hole; while the filtering elements are used for filtering, the two filtering elements are always communicated with the top suction nozzle and the bottom suction nozzle, and two-way time-staggered backwashing is formed under the action of external pressure difference.

Description

technical field [0001] The invention relates to the technical field of lubricating system oil filtration, and more specifically relates to a self-cleaning filter with self-operated two-way time-staggered backwashing and a filtering and backwashing method thereof. Background technique [0002] The filter with self-cleaning function can realize body cleaning and restore the oil flow channel of the filter element. With the development of ship engine room towards unmanned duty, filters with self-cleaning function will be more and more applied to various fluid media. The self-cleaning filters in the oil system mainly include compressed air self-cleaning filters and rotary arm liquid self-cleaning filters. Compressed air self-cleaning filters are easy to bring in algae and silt, and the cleaning is uneven, the structure is complex, there are many potential failure points and leakage points, the reliability and maintainability are poor, and the actual application effect is not goo...
