[0025] Specifically, such as Figure 2 and Figure 3 As shown, a cylindrical inner filter barrel 4 is fixed inside the tank cover 2. Eight sets of plate-shaped first support plates 401 are fixed to the outer side of the inner filter barrel 4 close to the outer filter barrel 5. A first filter element 403 is filled between the first support plates 401. The bottom of the inner filter barrel 4 is a plate-shaped first bottom plate 402, which facilitates the first bottom plate 402 to guide the oil filtered in the inner filter barrel 4 to the first filter element 403 for secondary filtration of the oil.
