Problems solved by technology

Generally, silicon smelting in China adopts the method of feeding in the furnace. The feeding in the furnace is carried out through the smoke top of the smelting furnace, which has the following defects: ① The renovation period of the old furnace is long. The system modification results in a long modification period and delays in production time; ②When feeding, the distribution of materials in the furnace is concentrated and uneven, resulting in the need for staff to re-feed and pick up materials in the triangular area of ​​the furnace, which affects the furnace condition and increases the labor intensity of the staff ; ③The maintenance cost is high, and the feeding system needs to be inspected and maintained regularly; ④The cooling structure and rotating structure in the feeding system have a high failure frequency, and maintenance and replacement of parts need to be shut down. Even if the furnace is shut down, the temperature in the furnace is high. There is water in the feeding trough, which poses a relatively large safety hazard and affects the personal safety of the staff
[0003] In order to overcome the above problems, some enterprises have introduced external feeding vehicles used abroad. The external feeding vehicles are loaded and fed mechanically. However, they have the following defects: ①The purchase cost of the charging vehicle is high; ②The maintenance cost is high, and the machine of the charging vehicle The body is often operated at high temperature, and the replacement of parts is frequent; ③The weight of the feeding truck itself is large, which requires a large range of operating sites, and it is necessary to change the structural strength and area of ​​the existing factory building; ④The distribution of materials is concentrated and uneven, and the distribution of materials The range is small and there is no continuity of feeding, which leads to a long feeding time, which affects the furnace condition, resulting in the need for staff to re-feed and pick up materials in the triangular area of ​​the furnace, which increases the labor intensity of the staff.

Embodiment

[0033] like Figure 1-Figure 3As shown, when using the present invention to charge the smelting furnace, the staff starts the control box 12, and the control box 12 starts the corresponding power system that is arranged on the vehicle frame 6, and the power system drives the travel wheel 7 to rotate, and the rotation of the travel wheel 7 Drive the movement of vehicle frame 6, because support 8, automatic feeding device 1, operating handle 4, rotating device 9, blower fan 5 are all arranged on the vehicle frame 6, vehicle frame 6 drives support 8, automatic The feeding device 1, the operating handle 4, the rotating device 9, and the fan 5 move to the smelting furnace. When the frame 6 moves to the feeding position, the power system stops working, and the control box 12 opens the feeding port 5, and the ingredients pass through the feeding port. 5 Enter the automatic feeding device 1, the automatic feeding device 1 conveys the ingredients to the material distribution device 2, ...

Abstract

The invention belongs to the technical field of silicon smelting equipment, and in particular, relates to an automatic feeding device for a silicon smelting furnace and an application method thereof.The automatic feeding device for the silicon smelting furnace comprises an automatic feeding device for receiving ingredients and conveying the ingredients to a next device or procedure, a distribution device hinged to a discharge end of the automatic feeding device for receiving the ingredients of the automatic feeding device and reasonably distributing the ingredients on a section in the furnace, a control mechanism for controlling the distribution device to realize an A-B reciprocating motion and controlling the automatic feeding device to realize a C-D reciprocating motion, and a walking device for realizing movement of an automatic feeding device body. According to the automatic feeding device for the silicon smelting furnace and the application method thereof, existing factory buildings or equipment does not need to be improved, uniform distribution and a wide distribution range are achieved in the feeding process, maintaining is convenient, maintenance cost is low, and continuous feeding is realized.

Description

technical field [0001] The invention belongs to the technical field of silicon smelting equipment, and in particular relates to an automatic feeding device for a silicon smelting furnace and a use method thereof. Background technique [0002] Silicon is an important metallurgical, chemical, electronic, and optical material. It plays an important role in information, communications, aerospace, environmental protection, and solar silicon cells. The market demand is also increasing. In the silicon smelting industry, it is necessary to add the prepared mixture into the silicon smelting furnace. The existing charging methods include two kinds of charging in the furnace and feeding outside the furnace. Generally, silicon smelting in China adopts the method of feeding in the furnace. The feeding in the furnace is carried out through the smoke top of the smelting furnace, which has the following defects: ① The renovation period of the old furnace is long. The system modification r...
