The blocking net 231 and the dust removal component 27 are on opposite sides. The wind generated by the dust removal component 27 discharges the smoke and dust from the inside of the air outlet pipe 233, and the inclined plate 232 can prevent the poured low-carbon ferrosilicon from falling into the vent 26.

[0029] A slide groove 255 is provided on one side of the feed opening 25, and a screening component 251 for screening low-carbon ferrosilicon is slidably connected inside the slide groove 255. A distinguishing opening 252 is provided on one side of the feed opening 25, and a support plate 254 is fixedly installed on the inner wall of the feed opening 25. The support plate 254 is located on one side of the distinguishing opening 252. A vibration component 253 for hitting the screening component 251 to generate vibration is fixedly installed on one side of the feed opening 25. The support plate 254 can allow the screening component 251 to have a bottom to hold after installation, and the distinguishing opening 252 can allow the low-carbon ferrosilicon that does not meet the requirements to be distinguished.

[0030] The screening component 251 includes a slider 2511 movably installed inside the slide groove 255, a rotating groove 2514 penetrating through one side of the slider 2511, a cross bar 2512 fixedly installed on one side of the rotating groove 2514, a handle 2513 fixedly installed on one side of the slider 2511, a ring 2515 sleeved on the outer surface of the rotating groove 2514, and a filter 2516 fixedly installed on one side of the ring 2515.

[0031] The vibration assembly 253 includes a motor A2531 fixedly installed on one side of the discharge port 25, a driving rod A2532 movably arranged on one side of the motor A2531, and the driving rod A2532 passes through one side of the discharge port 25, an eccentric block 2533 is sleeved on the outer surface of the driving rod A2532, and the eccentric block 2533 is directly below the filter 2516. The eccentric block 2533 is driven to rotate by the driving rod A2532, and then continuously hits the filter 2516 to produce a vibration effect.

[0032] A feed port 11 is provided on the upper surface of the main body 1, and the feed port 11 is communicated with the discharge port 25. A water tank 12 is fixedly installed on one side of the main body 1, and a slide plate 13 is fixedly installed on the inner wall of the main body 1, and the slide plate 13 is directly below the feed port 11. A conveyor belt 14 is movably connected to the inner wall of the main body 1. Low-carbon ferrosilicon that meets the standards can enter the surface of the slide plate 13 through the feed port 11 and then fall onto the conveyor belt 14. The conveyor belt 14 then transports the low-carbon ferrosilicon to the inside of the water tank 12 for subsequent washing.

[0033] Specifically, when low-carbon ferrosilicon needs to be screened and loaded, first open the side door 22 and install the slider 2511 of the screening component 251 against the slide chute 255. At this time, the filter screen 2516 must be placed on the upper surface of the support plate 254. Then, when the flip cover 21 is opened, the vibration component 253 and the dust removal component 27 are started at the same time. At this time, the low-carbon ferrosilicon can be poured into the screening tube 2. Because the dust removal component 27 is opened in advance, the driving rod B274 inside the dust removal component 27 will drive the blades 275 to rotate at high speed to generate wind force. Then the wind force generated by the blades 275 will blow the smoke and dust on the surface of the low-carbon ferrosilicon to the vent 26 on the opposite side. Because the vent 26 is fixedly connected to the outlet pipe 233, the smoke and dust will finally be discharged through the outlet pipe 233. At this time, the low-carbon ferrosilicon will pass through the slide chute 24 to arrive Because the vibration component 253 is started, the eccentric block 2533 of the surface of the screening component 251 will hit the filter screen 2516 at random, causing the filter screen 2516 to vibrate. Because the ring 2515 on one side of the filter screen 2516 is mounted on the cross bar 2512, and because the filter screen 2516 is above the support plate 254, the filter screen 2516 will keep moving up and down. At this time, the low-carbon ferrosilicon that has not reached the specified size will be gradually thrown from the surface of the filter screen 2516 to the partition port 252 and finally directly discharged. The low-carbon ferrosilicon that has reached the specified size can directly pass through the surface of the filter screen 2516, arrive at the slide plate 13, and then slide to the surface of the conveyor belt 14. Finally, the conveyor belt 14 will transport the low-carbon ferrosilicon to the inside of the water tank 12 on one side of the main body 1 for washing, thereby achieving the effect of effectively discharging smoke and dust when the low-carbon ferrosilicon is loaded.
