1. The filter cartridge comprises a filter cartridge body, a material discharging pipe, a material inlet pipe, a support ring, a positioning column, a central hole, a pressing device, a slag discharging pipe, a blocking plug, an overflow pipe, a lower supporting plate, an oil outlet hole, a positioning block, a positioning hole, a filter screen, a upper supporting plate, a filter paper, a sleeve, a pressing rod, a spring, a through groove and a sliding block.

Detailed Description

The following describes embodiments of the present utility model in further detail with reference to FIGS. 1-7.

The first embodiment solves the technical scheme that the filter cartridge 1 is in flange connection with the end cover 2, is simple in structure, is convenient to operate and is high in practicability, and the filter cartridge 1 and the end cover 2 are convenient to detach, so that the secondary filter cartridge is convenient to clean and replace. The secondary filter core that is equipped with can carry out double filtration to lubricating oil through filter screen 16 and filter paper 18, and large granule impurity in the lubricating oil can be filtered to filter screen 16, and the filter screen 16 can further filter the small granule impurity in the lubricating oil, and the lubricating oil flow direction that filters through the secondary filter core is strained slag tap 9 departments of 1 bottoms of section of thick bamboo and is precipitated, further makes the impurity precipitation that the secondary filter core can't handle at slag tap 9, and lubricating oil clear liquid then is discharged from overflow pipe 11. When the sediment needs to be removed, the lower stop plug 10 is disassembled for cleaning. The flange connection, namely the flange plate is connected by matching with the bolt, so that the disassembly is convenient, and the fastening effect is good.

In the second embodiment, when the filter cartridge is used, lubricating oil to be filtered is introduced into the filter cartridge 1 from the oil inlet pipe 3 on the end cover 2, the lubricating oil firstly enters the upper side of the support ring 5 in the filter cartridge 1, then the lubricating oil is filtered by the filter screen 16 and the filter paper 18 of the secondary filter cartridge in sequence, and then flows to the lower side of the filter cartridge 1 through the oil outlet hole 13 on the lower supporting plate 12 and the central hole 7 on the support ring 5, namely flows to the direction of the slag outlet pipe 9. When the lubricating oil flows through the filter screen 16 and the filter paper 18, the large-particle impurities and the small-particle impurities are filtered successively, then the lubricating oil enters the slag discharging pipe 9, part of impurities which are not treated by the secondary filter element are precipitated at the slag discharging pipe 9, and the filtered clear liquid can be discharged through the overflow pipe 11. The lubricating oil is filtered by the secondary filter element and deposited by the slag discharging pipe 9, and the filtering effect is good.
