However, the existing screening devices do not have the function of adjusting the mesh size. When screening aggregates of different sizes and specifications, it is necessary to replace the sieve mesh, and the disassembly and installation of the sieve mesh are relatively troublesome, thus affecting the work efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, an amorphous refractory screening device includes a frame 1. At one end of the top of the frame 1, two symmetric slide rails 11 are provided. A screening assembly 2 is movably assembled along the length direction of the slide rails 11. At the other end of the screening assembly 2, a driving assembly 3 is installed to drive the screening assembly 2 to reciprocate along the length direction of the slide rails 11. A collecting box 4 is placed directly below the screening assembly 2;

[0021] Among them, the screening assembly 2 includes a sieve box 201. The sieve box 201 is a box-shaped structure with an open top. A plurality of equally spaced square sieve holes are formed at the bottom of the sieve box 201. Connecting frames 207 are fixedly connected to both ends of the sieve box 201. A limiting block 203 is integrally formed on the inner side wall of the connecting frame 207 close to the bottom of the sieve box 201. A sieve plate 204 is provided between the sieve box 201 and the limiting block 203. A first L-shaped connecting plate 202 is fixedly connected to one end of the sieve box 201. A second L-shaped connecting plate 205 is fixedly connected to one end of the sieve plate 204 close to the first L-shaped connecting plate 202. A screw 206 is arranged between the second L-shaped connecting plate 205 and the first L-shaped connecting plate 202. One end of the screw 206 is rotatably connected to the second L-shaped connecting plate 205, and the screw 206 is threadedly connected to the first L-shaped connecting plate 202; the screening assembly 2 further includes rollers 208 that are adapted to the slide rails 11. There are two groups of rollers 208, and the two groups of rollers 208 are respectively rotatably connected to both ends of the connecting frame 207 through bearings.

[0022] In this embodiment: Since the existing amorphous refractory screening device does not have the function of adjusting the mesh size, when screening aggregates of different sizes and specifications, it is necessary to replace the sieve mesh, and the disassembly and installation of the sieve mesh are relatively troublesome, which affects the work efficiency. Therefore, in this solution, by setting the screening assembly 2, the sieve hole size can be adjusted according to requirements to meet different screening needs, without replacing the sieve mesh, saving a lot of time and indirectly improving the screening efficiency.

[0023] Specifically, when screening the unshaped refractory materials, first adjust the size of the sieve holes according to the screening requirements. By turning the screw rod 206, relative movement occurs between the sieve box 201 and the sieve plate 204. As a result, the sieve holes on the sieve box 201 and the sieve holes on the sieve plate 204 are staggered, and thus the size of the sieve holes is changed. It should be noted that the sieve holes in this solution are of square structure, and the sieve box 201 and the sieve plate 204 are diagonally opposite and parallel to each other. Therefore, when the sieve holes on the sieve box 201 are aligned with the sieve holes on the sieve plate 204, the two sieve holes overlap, and this is the maximum aperture. When relative movement is forced between the sieve box 201 and the sieve plate 204 by turning the screw rod 206, the sieve holes on the sieve box 201 and the sieve holes on the sieve plate 204 change from a larger square to a smaller square, thus realizing the change of the sieve hole size to meet the requirements of different screening processes.

[0024] Please refer specifically to Figure 2 and Figure 3 , the sieve plate 204 is provided with the same number of sieve holes as the sieve box 201, and the sieve holes of the sieve plate 204 are the same in structure and size as the sieve holes on the sieve box 201; the sieve holes on the sieve box 201 and the sieve holes on the sieve plate 204 are arranged in the same position; the gap between the sieve box 201 and the limit block 203 is matched with the thickness of the sieve plate 204.

[0025] In this embodiment: the sieve plate 204 is closely attached to the bottom of the sieve box 201. The relative movement between the sieve box 201 and the sieve plate 204 can be limited by the gap between the limit block 203 and the sieve box 201, so as to ensure that the sieve plate 204 closely attached to the bottom of the sieve box 201 makes relative movement, thereby completing the adjustment of the sieve hole size.

[0026] Please refer specifically to Figure 1 , the driving assembly 3 includes a motor 301. The output end of the motor 301 is connected with a driving wheel 302. One end of the upper surface of the frame 1 near the motor 301 is provided with a driven wheel 303. The driven wheel 303 and the driving wheel 302 are connected by belt drive. A connecting rod 304 is arranged between the driven wheel 303 and the screening assembly 2; one end of the connecting rod 304 is rotatably connected to the sieve box 201 through a shaft rod, and the other end of the connecting rod 304 is rotatably connected to the outer circumference edge of the driven wheel 303.

[0027] In this embodiment: the driving wheel 302 is driven to rotate by the motor 301, and the driving wheel 302 drives the driven wheel 303 to rotate through the belt. The rotating driven wheel 303 will drive the screening assembly 2 to reciprocate at a high frequency along the length direction of the slide rail 11 through the connecting rod 304 to realize the screening of the unshaped refractory materials. It should be noted that the driven wheel 303 in this solution is installed on a bracket, the bracket is fixed on the frame 1, and the driven wheel 303 and the bracket are rotatably connected through bearings.

[0028] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
