The bottom of the filter cartridge 4 is a filter screen 5, and the bottom of the filter hole is connected with a collection pipe 3.

Further, the filter screen 5 is embedded in the bottom inner wall of the filter cartridge 4, and the middle part of the filter screen 5 is solid and connected to the output shaft of the rotating motor 6, and the rotating motor 6 is connected to the filter cartridge through a bracket rod 4 within.

Further, the installation part of the filter cartridge 4 is provided with an installation hole, and the installation rod 7 passing through the liquid collection tank 2 is provided in the workbench 1, and the upper part of the installation rod 7 is threaded, and is equipped with Lock nut 8.

Further, the workbench 1 is provided with a spring hole on the outside of the installation rod 7, and the installation spring 9 sleeved on the installation rod 7 is arranged in the spring hole, and the upper part of the installation spring 9 and the filter cartridge 4 are Contact fit, after the filter cartridge 4 is installed, the installation spring 9 is in a compressed state, and the lock nut 8 is a nut with a screw on the top.

The beneficial effects of the utility model are:

1. A filter hole connected to the liquid collection tank is set on the work station, and a filter cartridge is set in the filter hole, and the filter is filtered through the filter under the filter cartridge, which saves the space occupied by the filter and avoids the damage of waste debris The collection pipe facilitates the collection of filtered waste chips together with processing waste chips.

2. The design of the rotating motor can realize the rotation of the filter screen, thereby preventing the waste debris on the filter screen from accumulating more and blocking the filter screen.

3. The design of the installation rod and lock nut can ensure that the installation part of the filter cartridge can be close to the liquid collection tank, thereby preventing waste from falling into the collection pipe from the gap between the two.

4. The design of the spring installation can facilitate the removal of the filter cartridge when cleaning the waste debris of the filter cartridge, and the screw block design on the lock nut can be locked without tools.
