[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model embodiment discloses a filtering device for producing fipronil with a multi-stage filtering mechanism.

[0024] Embodiment 1

[0025] Reference Figure 1-2 A filtering device for producing fipronil with a multi-stage filtering mechanism comprises a base 1, two support plates 2 are fixedly connected to the upper surface of the base 1, a first mounting hole is opened on one side of the two support plates 2, a first filter cartridge 3 is rotatably connected to the inside of the two first mounting holes, second mounting holes are opened at both ends of the first filter cartridge 3, a second filter cartridge 4 is rotatably connected to the inside of the two second mounting holes, a third mounting hole is opened on the outer surface of the first filter cartridge 3, a first filter screen 10 is fixedly connected to the inside of the two third mounting holes, a fourth mounting hole is opened on the outer surface of the second filter cartridge 4, a second filter screen 11 is fixedly connected to the inside of the two fourth mounting holes, and the mesh size of the first filter screen 10 is smaller than the mesh size of the second filter screen 11.

[0026] Fipronil is placed in the second filter cartridge 4 , and then filtered through the second filter screen 11 and falls into the first filter cartridge 3 , and then filtered through the first filter screen 12 to filter the fipronil again.

[0027] Reference Figure 1-3 A driving mechanism is provided on one side of one support plate 2, and the first filter cartridge 3 and the second filter cartridge 4 are both rotated by the driving mechanism. The driving mechanism includes an L-shaped plate 5, a motor 6, a gear 7, an inner gear ring 8 and an outer gear ring 9. The L-shaped plate 5 is fixedly connected to one side of the support plate 2, the motor 6 is fixedly connected to one side of the L-shaped plate 5, the gear 7 is fixedly sleeved on the output end of the motor 6, the inner gear ring 8 is fixedly connected to one side of the first filter cartridge 3, the outer gear ring 9 is fixedly sleeved on the outer surface of the second filter cartridge 4, and the inner gear ring 8 and the outer gear ring 9 are both meshed with the gear 7.
