[0025] A filter for furan resin production includes a tank body 1, the top of the tank body 1 is fixedly connected to a lid 2, the outside of the tank body 1 is fixedly connected to a reinforcing strip 3, the top of the lid 2 is fixedly connected to a lower hopper 4, the lower hopper 4 and the interior of the tank body 1 are interconnected, the interior of the tank body 1 is fixedly connected to an extension plate 5, the outside of the extension plate 5 is rotatably connected to a disc 6, the eccentric part of the disc 6 is fixedly connected to a sliding column 7, the outside of the sliding column 7 is slidably connected to a waist groove 8, and the outside of the waist groove 8 is fixedly connected to a swing bar 9. By placing the tank body 1 to a specified position, by pouring the mixed furan resin raw material from the inside of the lower hopper 4, and falling into the inside of the tank body 1 due to gravity, by rotating the disc 6, the sliding column 7 is rotated along the eccentric part of the disc 6, and at the same time the sliding column 7 squeezes the waist groove 8, so that the swing bar 9 swings.

[0026] For further information, see Figure 2 、 Figure 3 and Figure 4 In this embodiment, a rotating shaft is fixedly connected to the middle part of the swing bar 9, and the rotating shaft extends to the inside of the extension plate 5. A tooth plate 10 is fixedly connected to the bottom of the swing bar 9, and the outside of the tooth plate 10 is engaged with a tooth groove 11. When the slide column 7 squeezes the waist groove 8, the rotating shaft is used to limit the middle part of the swing bar 9, so that the swing bar 9 swings, and then the tooth plate 10 will swing with it and engage with the tooth groove 11.

[0027] For further information, see Figure 2 、 Figure 3 and Figure 4 In this embodiment, the outside of the tooth groove 11 is fixedly connected to the horizontal shaft 12, the outside of the horizontal shaft 12 is slidably connected to the limit seat 13, and the left and right ends of the horizontal shaft 12 are rotatably connected to the swing rod 14. The tooth plate 10 and the tooth groove 11 are engaged with each other, and then the rotational force will be transmitted to the horizontal shaft 12. At the same time, the limit seat 13 will limit the horizontal shaft 12, so that the horizontal shaft 12 can slide back and forth inside the limit seat 13, and the swing rod 14 can move synchronously with the horizontal shaft 12.

[0028] For further information, see Figure 2 、 Figure 3 and Figure 4 In this embodiment, the end of the swing rod 14 away from the horizontal axis 12 is fixedly connected to a rectangular frame 15, and the rectangular frame 15 is designed with an inclined structure. The bottom end of the inner side of the rectangular frame 15 is fixedly connected to the filter screen 16. When the horizontal axis 12 slides back and forth, it will drive the rectangular frame 15 to swing, and then the furan resin raw material will be screened inside the filter screen 16. Particles with a volume smaller than the filter screen 16 will automatically fall into the interior of the tank body 1, and particles with a volume larger than the filter screen 16 will remain on the surface of the filter screen 16.

The outside of the rectangular frame 15 is fixedly connected to a slider 18. A chute is provided at a position corresponding to the slider 18 on the inner wall of the tank body 1. Due to the overall inclined design of the rectangular frame 15, the unscreened particles will flow to the interior of the connecting pipe 17. At the same time, the chute will limit the slider 18, so that the rectangular frame 15 can move along the specified route.

The middle part of the guide plate 20 is designed in a funnel-shaped structure. When the raw materials are poured from the inside of the lower hopper 4, they rotate through the rotating shaft, and then the crushing rollers 19 rotate with each other to further crush the raw materials. At the same time, the funnel-shaped design of the guide plate 20 enables the raw materials to fall from the guide plate 20 to the inside of the rectangular frame 15 after crushing.

[0031] For further information, see Figure 1 and Figure 5In this embodiment, a connecting sleeve 21 is fixedly connected to the inner wall of the tank body 1 and located outside the connecting pipe 17.

[0032] In this embodiment, the implementation scenario is specifically as follows: by placing the tank body 1 to a specified position, by pouring the mixed furan resin raw material from the inside of the lower hopper 4, it falls into the inside of the tank body 1 due to gravity, and is rotated by the rotating shaft, and then the crushing rollers 19 rotate with each other to further crush the raw material, and at the same time the funnel-shaped design of the guide plate 20 enables the raw material to fall from the guide plate 20 to the inside of the rectangular frame 15 after crushing, by rotating the disc 6, and then the slide column 7 rotates along the eccentric part of the disc 6, and at the same time the slide column 7 squeezes the waist groove 8, and at the same time limits the swing bar 9 and the middle part through the rotating shaft to realize the swing bar 9 swinging, and then the tooth plate 10 will swing with it and engage with the tooth groove 11, and then the rotational force will be transmitted to the horizontal axis 12, and at the same time the limit seat 13 will 12 is limited, so that the horizontal axis 12 slides back and forth inside the limiting seat 13, and the swing rod 14 moves synchronously with the horizontal axis 12, which will drive the rectangular frame 15 to swing, and then the furan resin raw material is screened inside the filter screen 16. Particles with a volume smaller than the filter screen 16 will automatically fall into the interior of the tank body 1, and particles with a volume larger than the filter screen 16 will stay on the surface of the filter screen 16. The rectangular frame 15 is designed to be inclined as a whole, so that the unscreened particles will flow to the inside of the connecting pipe 17, and the unscreened particles will fall from the inside of the connecting pipe 17 and the connecting sleeve 21 to the inside of the collecting cylinder 22, and then the auger 24 will transfer the raw materials inside the collecting cylinder 22 to the inside of the connecting pipe 17, and then start the suction fan 25 to suck the raw materials into the interior of the tank body 1, and further crush them through the crushing roller 19 and filter them again.
