Most of the screening devices for fused magnesia production have too low efficiency during screening, and the screening is not fine enough, often requiring people to perform secondary screening, bringing more workload to people and reducing the work efficiency.

[0004] However, it still has the following drawbacks in actual use:

[0005] 1. For the above-mentioned screening device for fused magnesia production, two screenings can be completed through the upper screening mesh and the lower screening mesh. However, when there is a large amount of fused magnesia left in the screening mesh, it needs to be cleaned, otherwise it will affect the screening efficiency.

[0006] 2. For the above-mentioned screening device for fused magnesia production, a knocking plate is fixedly connected to the top of the vertical rod, a cam rod and a second motor are fixedly connected to the cross plate, a cam is movably connected to the cam rod, the cam is aligned with the knocking plate, and the output end of the second motor is connected to the input end of the cam through a belt.

[0034] The operation process of this embodiment is as follows: The fused magnesia is added into the screening box 1 through the feeding port 108 of the screening box 1 for screening. During the falling process, it will pass through the filter plate 105, and the filter plate 105 conducts the first screening. At the same time, larger particles will be discharged from the discharge port 107 of the screening box 1 and fall into the collection box 102 for collection. After a period of time, the electric telescopic rod 201 is started to push the connector 202 and the mounting plate 203 to move. The mounting plate 203 drives the brush 204 to move on the surface of the filter plate 105, and the brush 204 cleans the surface of the filter plate 105 to avoid the situation that the blockage of some filter holes affects the filtering effect. Specific Embodiment Two

[0036] Please refer to Figure 1 、 Figure 2 and Figure 4 Based on Specific Embodiment One, a screening assembly 3 is installed on the inner sidewall of the screening box 1. The screening assembly 3 facilitates the multiple screening of materials, realizes automatic screening, and can also save energy consumption.

[0037] Specifically, the upper and lower ends of the screening plate 301 are detachably and fixedly connected to the fixing plate 302. The fixing plate 302 facilitates the fixation of the screening plate 301. The fixing plate 302 is fixedly connected to the inner side wall of the screening box 1 to fix the fixing plate 302 so as to achieve a better fixing effect. At the same time, the right side wall of the screening plate 301 is fixedly connected to the connecting plate 303. The connecting plate 303 plays a connecting role.

At the same time, the fixed end of the return spring 304 is fixedly connected to the screening box 1 to fix the return spring 304 so as to better compress and extend. At the same time, the filtering holes opened on the right side of the screening plate 301 are larger than those opened on the left side, which is convenient for screening. And the screening plate 301 is installed with the right side inclined downward, which is convenient for moving under the gravity of the material itself. The lower side wall of the screening plate 301 is fixedly connected to the installation shell 305. The inner side wall of the installation shell 305 is fixedly connected to the vibrator 306 to facilitate driving the screening plate 301 to vibrate. At the same time, the vibrator 306 is electrically connected to the controller 101, and the working time of the vibrator 306 is controlled on the controller 101.

[0038] Furthermore, the filter plate 105 is inclined to facilitate filtration and separation. A drainage plate 106 is provided below the filter plate 105, and the drainage plate 106 is inclined. And a screening plate 301 is provided below the drainage plate 106. The above components realize that the material passing through the filter plate 105 falls on the screening plate 301 through the drainage plate 106 for secondary screening.

[0039] The operation process of this embodiment is as follows: The fused magnesia after the first screening falls back to the left side of the screening plate 301 through the drainage plate 106. The vibrator 306 is controlled to work on the controller 101, driving the installation shell 305 and the upper screening plate 301 to vibrate. The material will vibrate along with the screening plate 301 to prevent larger particles from blocking the screening plate 301. At the same time, during the up-and-down vibration of the screening plate 301, the reset spring 304 will be compressed and extended. When the vibrator 306 is turned off, the screening plate 301 can also be driven to vibrate up and down under the action of the reset spring 304. Furthermore, by controlling the working time of the vibrator 306 on the controller 101, continuous vibration of the screening plate 301 for screening can be achieved, which can reduce power consumption to save costs, and at the same time achieve the effect of automatic screening. The smaller particles on the screening plate 301 will fall into the lower collection box 104 for storage. Under the action of gravity, and because the screening plate 301 is inclined, the larger particles will fall to the right side of the screening plate 301 and fall through the right side with larger filter holes into the lower collection box 104 for storage, completing the collection and screening of different particle sizes. The fused magnesia that has not fallen through the filter holes of the screening plate 301 will fall from the rightmost side of the screening plate 301 into the collection box 104 for storage, completing the effect of multiple screenings.
