Description

Technical Field

[0001] The utility model relates to the technical field of silicon smelting, in particular to a silicon slag collecting device for metallic silicon smelting. Background Art

[0002] Silica slag is a water-containing mixture obtained by alkali fusion, acid leaching and water dissolution of zircon sand. It is a colloidal polymer with a high water content and has high utilization value. It can be recycled or used as a deoxidizer. In order to make it meet the national standards, the crude liquid must be clarified and separated after desiliconization, and the silica slag must be collected.

[0003] When optimizing the existing silicon slag collection device for metallic silicon smelting, most of the focus is on how to transport the silicon slag out faster and collect it. For example, the Chinese utility model patent with application number CN201811318338.6 discloses "A silicon slag collection device for industrial silicon smelting". In this device, it includes a box body and a feeding hopper. The top of the box body is connected to the feeding hopper. The inner side of the box body is provided with a conveying device, which includes a first motor and a reciprocating screw. The right end of the box body is fixedly connected to the first motor. The main shaft of the first motor The end is fixedly connected to a reciprocating screw, the inner side of the reciprocating screw is slidably connected to a screw slider, the bottom end of the screw slider is fixedly connected to a slider, the bottom end of the slider is fixedly connected to a first socket plate, and the inner side of the first socket plate is socketed with a second socket plate. The reciprocating screw, screw slider and slider are arranged, and the reciprocating screw mechanism used has a compact structure and is safe and reliable during operation. The reciprocating screw can effectively transport larger pieces of silicon slag out of the box. In addition, the device has a good feeding effect and can effectively improve work efficiency.

[0004] Although the above-mentioned silicon slag collection device for metallic silicon smelting has certain advantages in how to transport and collect silicon slag faster, it still has certain disadvantages: when the reciprocating screw is used to transport larger pieces of silicon slag out of the box, slag is still likely to remain in the box. In order to discharge it in time, the silicon slag is gradually separated and enters the sedimentation tank. If there is no partition structure, the slag is likely to overflow. Utility Model Content
