The two blocking plates 13 are located below the feeding pipe 6, and the outer sleeves of the two cross bars 16 are installed with springs 15;

[0021] The inner wall of the body 8 is fixedly installed with a first screen frame 10, and the inner wall of the body 8 close to the first screen frame 10 is fixedly installed with a second screen frame 12, and the second screen frame 12 is inclined in the opposite direction to the first screen frame 10. The first screen frame 10 and the second screen frame 12 are used to facilitate multiple screening of refractory materials and improve the screening effect. An intermittent drive component is provided inside the body 8, and a collecting box 9 is fixedly installed on the inner bottom of the body 8 to facilitate the collection of the screened refractory materials. A plurality of support legs 2 are fixedly connected to the bottom of the body 8, and the support legs 2 are provided. The legs 2 are convenient for supporting the screening device to ensure that it is more stable during use. A first discharge port 3 is opened through the surface of the body 8 near the first screen frame 10, and a second discharge port 11 is opened through the surface of the body 8 near the second screen frame 12. The first discharge port 3 and the second discharge port 11 are provided to facilitate the discharge of the screened refractory material. Two clamping plates 1 are rotatably connected to the surface of the body 8, and the surfaces of the two clamping plates 1 are clamped and installed on the surface of the collecting box 9.

[0022] like Figure 2 and Figure 3As shown, the intermittent drive assembly includes two first rotating shafts 5, which are rotatably connected to the outside of the body 8. The bottoms of the two first rotating shafts 5 are fixedly connected to cams 17, and the top of the body 8 is rotatably connected to the second rotating shaft 7.
