In practical application, the number of layers of the impurity filtering net can be set according to the precision of filtering. The bottom plate 6 is obliquely fixed at the bottom in the barrel body 12, and the included angle between the bottom plate 6 and the horizontal plane is 10-30 degrees. The bottom plate 6 is provided with a first annular sleeve 61, a second annular sleeve 62 and a third annular sleeve 63, and the first annular sleeve 61, the second annular sleeve 62, the third annular sleeve 63 are respectively provided with a clamping groove which is hermetically matched with the lower ports of the first-stage filter screen 81, the second-stage filter screen 82 and the water collecting net 3. The lower end face of the upper gland plate 7 is respectively provided with a clamping groove which is in sealing fit with the upper ports of the first-stage filter screen 81, the second-stage filter screen 82 and the water collecting net 3, the upper gland 7 covers the upper port of the filter element, and then the upper gland plate is fixed on the barrel body 12 of the shell 1 through a plurality of long fixing rods 10. Go up and be equipped with a plurality of upper ear plates 71 along circumference on the lateral surface of gland 7, be equipped with a plurality of lower otic placodes 121 with upper ear plate 71 bolted connection on the medial surface of staving 12, through connecting upper and lower otic placodes, can prevent effectively that gland 7 from rocking about under the pressure effect. The outlet end 41 of the oil inlet pipe 4 extends from the bottom of the barrel body 12, then penetrates through the bottom plate 6 and reaches the upper part of the innermost first-stage filter screen 81, and the center of the outlet end 41 of the oil inlet pipe 4 is positioned on the axis of the first-stage filter screen 81. The flowline 5 is connected to the bottom of the barrel 12. A first dirt storage chamber is formed between the first annular sleeve 61 and the oil inlet pipe 4 and is used for receiving the impurities with the enlarged particles filtered by the first-stage filter screen 81; a second dirt storage chamber is formed between the second annular sleeve 62 and the first annular sleeve 61 and is used for receiving smaller-particle impurities filtered by the second-stage filter screen 82; a third water storage chamber is formed between the third annular sleeve 63 and the second annular sleeve 62 and is used for receiving water filtered by the water collecting net 3. A first sewage discharge port 64 is formed in the lowest position of the bottom plate 6 in the first-stage filter screen 81 at the innermost layer, and the first sewage discharge port 64 is positioned in the first sewage storage chamber; a second sewage draining outlet 65 is arranged at the lowest part of the bottom plate 6 between the first-stage filter screen 81 and the second-stage filter screen 82, and the second sewage draining outlet 65 is positioned in the second sewage storage chamber; the lowest part of the bottom plate between the second-stage filter screen 82 and the water collecting net 3 is provided with a third sewage draining outlet 66, and the third sewage draining outlet 66 is positioned in a third water storage chamber.
