This setting gasoline enters to inside filter lower casing from sump oil oil inlet pipe, the gasoline warp entered from sump oil oil inlet pipe Filtering screen, filter cotton layer and the filter paper layers three layer filtration in filter mechanism are crossed, filtered gasoline is arranged from edible vegetable oil flowline Out, so that the gasoline of filtering is limpider clean, by the setting of spring and pressing plate filter mechanism is stablized and suppresses The filter lower casing inner bottom fixed limit filter mechanism while, if oil inlet quantity is excessive, spring is certain there are also this Cushion performance.

Preferably, it is provided with mounting groove above the pressing plate, the spring bottom end is welded in inside mounting groove, the mounting groove For ring junction flute.

It is more firm above pressing plate that the mounting groove of this setting ring structure is mounted on spring bottom end.

Preferably, the filtering screen bottom end is equipped with open slot, and the open slot is round-like structure.

The open slot of this setting round-like structure enters to gasoline there are certain space, quickly filters conducive to gasoline.

Preferably, lower end is provided with external screw thread on the outside of the filter upper casing, and the outer upper side of the filter lower casing is provided with interior Screw thread, the filter upper casing are connected with filter lower casing screw thread.

This setting filter upper casing is connected with filter lower casing screw thread, more convenient for filter self-filtering mechanism It changes, reduces use cost, while the metal filtration mesh enclosure in filter mechanism is easily recycled, and also reduces the generation of waste and old rubbish.

Preferably, it is all provided on the outside of the filter upper casing and filter lower casing inside and pressing plate, spring and filtering screen There is zinc coat.

This is arranged so that filter overall structure has good anticorrosion and wear-resisting property.

Preferably, screw thread is provided on the inside of the sump oil oil inlet pipe.

The installation that screw thread is easy between filter oil inlet and oil inlet pipe is provided on the inside of this setting sump oil oil inlet pipe.
