The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, the utility model discloses a multi-bag filter, including barrel 1, barrel 1 is hollow cylinder, and the bottom of barrel 1 sets firmly three evenly distributed's landing leg 5. The cylinder cover 2 is installed on the top end of the cylinder body 1, the cylinder cover 2 is matched with the cylinder body 1, and a closed cavity is formed in the cylinder body 1. The top of the outer side wall of the barrel body 1 is provided with a liquid inlet pipe 3 communicated with the interior of the barrel body 1, and the bottom end of the barrel body 1 is provided with a liquid outlet pipe 4 communicated with the interior of the barrel body 1. Four filter baskets 9 are arranged in the cylinder body 1, a filter bag 10 is arranged in the filter basket 9, and the filter basket 9 plays a role in containing the filter bag 10. The unfiltered lubricating oil is injected into the cylinder body 1 through the liquid inlet pipe 3, is filtered by the filter bag 10, flows out through the filter basket 9 and finally flows out through the liquid outlet pipe 4, and the filtering of the lubricating oil is completed.

Referring to fig. 2 and 3, a partition plate 8 is fixedly arranged in the cylinder 1 and is arranged between the liquid inlet pipe 3 and the liquid outlet pipe 4, and the partition plate 8 divides a cavity in the cylinder 1 into two parts. Four placing holes 81 which are uniformly distributed are formed in the partition plate 8, and the filter basket 9 is placed in the placing holes 81. The top end of the outer side wall of the filter basket 9 is fixedly provided with an annular lug 91, and the lug 91 is arranged on the partition plate 8. The outer diameter of the lug 91 is larger than the diameter of the placement hole 81, and the lug 91 and the partition plate 8 cooperate with each other to function as a support for the filter basket 9.

Referring to fig. 3, an annular sealing gasket 11 is placed on the lug 91, and the sealing gasket 11 is made of rubber and is elastic. The top end of the filter bag 10 is provided with a collar 101 which is arranged on the filter basket 9, a sealing gasket 11 is arranged between the lug 91 and the collar 101, and the sealing gasket 11 plays a role in buffering and improving the sealing property between the collar 101 and the lug 91.

Referring to fig. 3 and 4, a support 13 disposed above the partition plate 8 is disposed in the cylinder 1, four clamp rings 12 are fixedly disposed at the bottom end of the support 13, the four clamp rings 12 respectively face the collar 101 and abut against the collar 101, the clamp rings 12 face the collar 101 and press the collar 101, and the filter bag 10 is fastened on the flange 141.

Referring to fig. 2 and 3, a spring 15 disposed in the cylinder 1 is fixedly disposed at the bottom end of the cylinder cover 2, a support plate 14 facing the spring 15 is fixedly disposed at the top end of the bracket 13, and the bottom end of the spring 15 abuts against the top end of the support plate 14. When the cover 2 is mounted on the can body 1, the spring 15 is in a contracted state, and the spring 15 plays a role of pressing the support plate 14, so that the collar 101 is further pressed on the flange 141 through the bracket 13 and the pressing ring 12. When the multi-bag filter is used for a period of time and the filter bag 10 needs to be replaced or impurities in the filter bag 10 needs to be poured, an operator opens the cylinder cover 2 and then takes out the support 13, and the support 13 drives the four clamp rings 12 to be taken out together, so that the filter bag 10 is replaced or the impurities in the filter bag 10 are poured.

Referring to fig. 2 and 4, the periphery of the top end of the support plate 14 is fixedly provided with a convex edge 141, the convex edge 141 is in a shape of a square, and the bottom end of the spring 15 is disposed in the convex edge 141.
