[0004] A multi-stage filtering device is provided to achieve the purpose of the utility model, including a supporting structure mounted on a cylinder body, the supporting structure including a fixed cylinder and a movable rod movably inserted in the fixed cylinder, three fixed cylinders are symmetrically arranged about the center of the cylinder body, an arc-shaped I-shaped clamping seat is arranged at the other end of the movable rod, and the I-shaped clamping seat is used to be clamped on the upper end edge of the cylinder body, the fixed cylinder and the movable rod are fixed by a locking rod, and a grid is commonly arranged at the upper ends of the three fixed cylinders, and a filter net is arranged on the grid, and a pressure ring is arranged on the upper end of the grid, and the pressure ring is connected to the fixed cylinder.

[0005] As a further improvement of the above solution, the upper ends of the three fixing cylinders are commonly connected to a circular ring base, and the circular ring base abuts against the lower end of the filter screen.

[0006] As a further improvement of the above solution, the upper end of the circular ring base is configured as an arc-shaped top.

[0007] As a further improvement of the above solution, the upper ends of the three fixing cylinders are provided with arc-shaped grooves for accommodating the grid.

[0008] As a further improvement of the above solution, three screws are arranged on the pressure ring about its center, and a threaded hole is arranged on each of the fixing tubes corresponding to one of the screws.

[0009] As a further improvement of the above solution, a rotating handle is provided at the upper end of the screw.

[0010] The beneficial effects of the utility model are:

[0011] Compared with the prior art, the utility model provides a multi-stage filtering device, which is mounted on the upper edge of the cylinder through an arc-shaped I-shaped clamp. After adjusting the position, the fixed cylinder and the movable rod are fixed together through a locking rod. Through the action of the grid frame and filter net installed on the upper end of the fixed cylinder, the liquid additives and emulsions are filtered one more time to reduce the impurities therein and reduce the clogging of the filter nets of subsequent equipment, thereby facilitating production. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings, wherein:

[0013] Figure 1 It is a schematic diagram of the structure of the utility model;

[0014] Figure 2 This is a schematic diagram of the structure of the utility model after the filter screen is removed. DETAILED DESCRIPTION

[0015] like Figure 1-Figure 2 As shown, the utility model provides a multi-stage filtering device, including a support structure mounted on a cylinder, the support structure including a fixed cylinder 1 and a movable rod 2 movably inserted in the fixed cylinder 1, three fixed cylinders 1 are symmetrically arranged about the center of the cylinder, the other end of the movable rod 2 is provided with an arc-shaped I-shaped card seat 3, the I-shaped card seat 3 is used to be clamped on the upper edge of the cylinder, the fixed cylinder 1 and the movable rod 2 are fixed by a locking rod 4, the upper ends of the three fixed cylinders 1 are commonly provided with a grid 5, and the upper ends of the three fixed cylinders 1 are all provided with an arc groove for accommodating the grid 5. The grid 5 is provided with a filter screen 6, and the upper end of the grid 5 is provided with a pressure ring 7, and the pressure ring 7 is connected to the fixed cylinder 1.

[0016] In one embodiment, the upper ends of the three fixing cylinders 1 are connected to a circular base 8, which abuts against the lower end of the filter screen 6. On the one hand, the circular base 8 supports the filter screen 6 to prevent the filter screen 6 from being loosened or damaged due to excessive weight on the filter screen 6.

[0017] Further improvement, the upper end of the annular base 8 is set as an arc top. When the liquid additives and emulsions fall to the upper end of the annular base 8, they will flow downward along the arc top to reduce liquid accumulation.

[0018] As a further improvement, three screw rods 9 are arranged about the center of the pressing ring 7, and a threaded hole is arranged on each fixed cylinder 1 corresponding to one screw rod 9. A rotating handle is arranged at the upper end of the screw rod 9. By twisting the screw rod 9, the filter screen 6 sandwiched between the pressing ring 7 and the fixed cylinder 1 can be replaced.

[0019] The above embodiments are not limited to the technical solutions of the embodiments themselves, and the embodiments can be combined with each other to form new embodiments. The above embodiments are only used to illustrate the technical solutions of the utility model and are not intended to limit them. Any modification or equivalent replacement that does not deviate from the spirit and scope of the utility model shall be included in the scope of the technical solution of the utility model.
