Detailed Description

Fig. 1 is a schematic structural diagram of an multi-stage filtering oil filter according to the present invention, and fig. 2 is a schematic structural diagram of a top view of a multi-stage filtering oil filter according to the present invention, as shown in fig. 1 and 2.

Referring to fig. 1 and 2, the multi-stage filtering oil filter provided by the invention comprises a shell 1, a filter cartridge 2, a filter element 3, a second filter element 4 and a driving mechanism;

a containing cavity is arranged in the shell 1, the th filter element 3 is positioned in the containing cavity to divide the containing cavity into a filter cavity positioned above the th filter element 3 and a liquid outlet cavity positioned below the th filter element 3, a liquid inlet is arranged at the top of the filter cavity, and a liquid outlet is arranged at the bottom of the liquid outlet cavity;

the filter cartridge 2 is vertically arranged in the filter cavity, the bottom of the filter cartridge 2 is sealed, the top of the filter cartridge 2 is communicated with the liquid inlet, the side wall of the filter cartridge 2 is provided with a filter screen structure, and the driving mechanism is connected with the filter cartridge 2 and used for driving the filter cartridge 2 to rotate around a rotating shaft of the filter cartridge 2;

the second filter element 4 is located in the filter cavity, the second filter element 4 is fixed with the filter cylinder 2 and extends spirally around the filter cylinder 2, the second filter element 4 adopts a folding filter material, a folding line of the folding filter material is radially arranged along the filter cylinder 2, and the outer edge of the second filter element 4 is matched with the side wall of the filter cavity in a sealing mode.

In the specific working process of the multistage-filtration oil filter, engine oil enters the filter cylinder through the liquid inlet, the drive mechanism drives the filter cylinder to rotate, the engine oil is thrown out of the filter cylinder under the action of centrifugal force, primary filtration and cloth of the engine oil are realized, the second filter element is upwards filter-pressed on the engine oil subjected to rough filtration along with the rotation of the filter cylinder, solid impurities in the engine oil are pushed to upwards move, and the engine oil subjected to filter-pressing downwards passes through the filter element and then is discharged from the liquid outlet cavity.

In this embodiment, the multistage filterable oil cleaner that provides, the filter core is located the shell will it separates for the filter chamber that is located the top and the play sap cavity that is located the below to hold the cavity, strain a vertical setting and be in the filter chamber, it has the filter screen structure to strain a lateral wall, actuating mechanism is connected with straining a section of thick bamboo and is used for the drive to strain a section of thick bamboo and rotate around its pivot, the second filter core with strain a section of thick bamboo fixed and around straining a section of thick bamboo spiral extension, the second filter core adopts folding filter media and its folding line along straining a section of thick bamboo radial arrangement.
