[0025] As Figure 2 And Figure 3As shown, the device further comprises a discharging assembly, which comprises a push plate 6, a spring 61 and a scraper 7. The upper, middle and lower portions of the front wall of the material frame 2 are slidably connected with the push plate 6. The rear portions of the three push plates 6 are slidably connected with the scraper 7. The scraper 7 is provided with eight springs 61 evenly distributed between the inner bottom wall and the rear portion of the adjacent push plate 6. The upper scraper 7 slides on the first screen 3, the middle scraper 7 slides on the second screen 31, and the lower scraper 7 slides on the baffle 8.
[0026] As shown in Figure 4 and Figure 6 As shown, the device further comprises a plug 101, which is connected to the middle portion of the front wall of the water storage tank 10.
[0027] As shown in Figure 1 As shown, the device further comprises a cover plate 15, which is rotatably connected to the top rear side of the material frame 2 for dust and noise prevention.
[0028] Initially, the water storage tank 10 is filled with an appropriate amount of clean water. When using the device, first turn the cover plate 15 upward to open, then pour the slag powder to be sieved into the material frame 2, and then turn the cover plate 15 downward to cover it. Start the vibrator 4, which will drive the first screen 3 and the second screen 31 to vibrate up and down through the connecting rod 5. The upward moving first screen 3 and the second screen 31 will press the adjacent scraper 7 to move upward, causing the spring 61 to deform. When the first screen 3 and the second screen 31 move downward, the scraper 7 moves downward under the elastic action of the spring 61 and returns to its original position.
[0029] The vibrating first screen 3 will perform coarse screening on the slag powder, removing most of the impurities that do not meet the requirements. The second screen 31 will further screen the material after coarse screening. The second screen 31 will have larger slag powder particles, while the fine slag powder will fall on the baffle 8.
