First embodiment

Referring to fig. 1 to 4, the present embodiment provides a filtering apparatus, which includes: the filter comprises a filter cartridge 10, a filter element 20 and a dirt storage part 30, wherein the filter element 20 is detachably arranged in the filter cartridge 10, the dirt storage part 30 is positioned between the filter cartridge 10 and the filter element 20, the dirt storage part 30 is connected with the filter element 20, and the dirt storage part 30 is provided with a dirt storage groove 35.

Specifically, the filter cartridge 10 has a liquid inlet 11 and a liquid outlet 12, and the liquid outlet 12 communicates with the inner cavity of the filter element 20.

When the filtering device is used for filtering, liquid to be filtered enters between the filter cartridge 10 and the filter element 20 through the liquid inlet 11 of the filter cartridge 10, and passes through the filter element 20 to enter the inner cavity of the filter element 20, impurities are blocked outside the filter element 20 in the process that the liquid passes through the filter element 20, namely the impurities are left between the filter element 20 and the filter cartridge 10, the liquid entering the inner cavity of the filter element 20 is the filtered liquid, and the liquid in the inner cavity of the filter element 20 is discharged out of the filter cartridge 10 through the liquid outlet 12 communicated with the inner cavity of the filter element 20, so that the filtering is completed.

Since the dirt storage member 30 is provided between the filter element 20 and the filter cartridge 10, impurities located between the filter element 20 and the filter cartridge 10 fall into the dirt storage groove 35 of the dirt storage member 30, and the impurities are precipitated in the dirt storage groove 35. During replacement of the filter element 20, the filter element 20 is removed from the filter cartridge 10, and the dirt storage member 30 is removed from the filter cartridge 10 together with the filter element 20, thereby preventing impurities in the dirt storage groove 35 from falling into the filter cartridge 10 and being discharged from the drain port 12 of the filter cartridge 10.

When being applied to the lubricating system of wind-powered electricity generation gear box with above-mentioned filter equipment, filter equipment can be used to carry out filtration treatment to the lubricating oil in the wind-powered electricity generation gear box, and can solve the problem that impurity sneaks into the lubricating oil after the filtration when changing lubricating oil among the prior art.

Preferably, the opening of the dirt storage groove 35 of the dirt storage member 30 faces upward, and the horizontal plane in which the top opening of the dirt storage groove 35 is located below the horizontal plane in which the bottom edge of the opening of the liquid inlet 11 of the filter cartridge 10 is located. With this arrangement, the impurities in the liquid entering through the liquid inlet 11 can fall into the dirt storage tank 35 by its own weight.

Further, a dirt storage member 30 is installed at the bottom of the filter cartridge 20. The filter element 20 is connected to the filter cartridge 10 at the top and bottom thereof, respectively, the dirt storage member 30 is installed at the bottom of the filter element 20, and the dirt storage member 30 is located between the filter element 20 and the filter cartridge 10, so that impurities in the lubricant oil introduced into the filter cartridge 10 can be dropped into the dirt storage member 30.

In a possible embodiment, the dirt storage member 30 and the filter element 20 are integrated, that is, the dirt storage member 30 and the filter element 20 are fixedly connected and cannot be detached, and the dirt storage member 30 is replaced together during the replacement of the filter element 20. So set up, need not to store up dirty piece 30 and carry out cleaning process, the operation process is convenient.

Alternatively, in a preferred embodiment, the waste reservoir 30 is removably connected to the filter cartridge 20. So set up, at the in-process of renew cartridge 20, no longer put into use after filter core 20 takes out, and store up dirty piece 30 and after the impurity clean up in the dirty groove 35 of storage, can be connected with new filter core 20 to put into use once more. By such arrangement, the consumption of the dirt storage part 30 can be reduced, the operation and maintenance cost is reduced, and the environment is protected.

In one possible embodiment, the dirt storage member 30 is snap-fit to the filter element 20. For example, the dirt storage member 30 is provided with a clamping block, the filter element 20 is provided with a clamping groove, and when the dirt storage member 30 is connected with the filter element 20, the clamping block extends into the clamping groove, so that the dirt storage member 30 is clamped and connected with the filter element 20.
