[0002] In the production of industrial silicon, silica is the main source of raw materials. Other materials such as charcoal, petroleum coke, and washed coal are used as reducing agents. The reducing agents and raw materials need to be mixed and stored in the silo in the early stage. In the actual operation, the mixed materials are transported to the electric arc furnace through the feeding pipe for the production of industrial silicon.
[0003] The existing technical problems are that the material feeding position of the feeding pipe remains unchanged, resulting in uneven distribution of the mixture into the electric arc furnace and severe local material accumulation, which leads to unstable operation of the electric arc furnace; the temperature at the top inlet of the electric arc furnace is high, which is not conducive to the use of electrical equipment, so the current electric material feeding equipment cannot be used; the mixture falls directly into the electric arc furnace through the feeding pipe, which causes certain impact damage to the electric arc furnace.

A hinge seat is rotatably connected to the middle of the second connecting rod, and the hinge seat is fixedly connected to the horizontal part of the rotating rod. The other end of the second connecting rod is rotatably connected to the telescopic end of the telescopic device.

The outer wall of the rotary joint 5 above the support plate 6 is fixed with a rotating rod 10.
[0025] The bottom end of the rotary joint 5 is rotatably connected to a chute 11;
[0026] Specifically, the material is discharged downward through the discharge pipe 1. The material is then fed to the rotary joint 5 via the discharge pipe 3 and the bend pipe 4 by the vibrating feeder 2. With the cooperation of the support plate 6, pulley 7 and annular slide rail 8, the rotary joint 5 is driven to rotate along the feed inlet of the electric arc furnace 9 by manually rotating the rotating rod 10. The rotation of the rotary joint 5 drives the chute 11 to rotate, realizing the left and right rotation of the chute 11 to distribute the material, thus expanding the distribution range.
[0027] A chute up-and-down adjustment device 12 is connected between the chute 11 and the rotating rod 10. Specifically, the chute up-and-down adjustment device 12 can drive the chute 11 to rotate up and down to distribute the material. With the cooperation of the rotary joint 5 and the chute up-and-down adjustment device 12, the material is evenly distributed in the chute 11, which reduces the labor intensity of the operator, improves the controllability of the material distribution, speeds up the work progress, and improves the work efficiency.
[0028] The rotating rod 10 includes a horizontal part 10.1, an inclined part 10.2 and a handle 10.3. One end of the horizontal part 10.1 is fixedly connected to the outer wall of the rotary joint 5, and the other end of the horizontal part 10.1 is fixedly connected to the inclined part 10.2. The other end of the inclined part 10.2 is fixedly equipped with a handle 10.3.
[0029] Specifically, the function of the rotating rod 10 is to facilitate manual control of the rotation angle of the rotary joint 5, ensuring the material discharge position of the chute 11. The operator can control the rotary joint 5 by standing at a position away from the electric arc furnace 9, thus reducing the high temperature impact of the electric arc furnace 9 on the operator.
[0030] The chute up-and-down adjustment device 12 includes a first connecting rod 12.1, a second connecting rod 12.2, and a telescopic device 12.3.

[0031] Specifically, the telescopic device 12.3 is set on the horizontal part 10.1 of the rotating rod 10. With the cooperation of the horizontal part 10.1 of the rotating rod 10, the telescopic device 12.3 is set at the feed inlet position away from the electric arc furnace 9, which can reduce the high temperature damage to the telescopic device 12.3.
[0032] It also includes a heat insulation cover 15, inside which is a bracket 14 and a telescopic device 12.3. The telescopic device 12.3 is an electric push rod. The purpose of setting up the heat insulation cover 15 is to further ensure the safe use of the telescopic device 12.3.
[0033] A number of inclined first guide plates 16 are uniformly fixed on one side wall of the chute 11, and a number of inclined second guide plates 17 are uniformly fixed on the other side wall of the chute 11. The first guide plates 16 and the second guide plates 17 are arranged alternately. Specifically, with the cooperation of the first guide plates 16 and the second guide plates 17, the drop and impact velocity of the material are reduced, and the impact damage to the inside of the electric arc furnace 9 is reduced.
[0034] The first guide plate 16 and the second guide plate 17 have the same structure, including a main body 16.1 and a buffer layer 16.2. The buffer layer 16.2 is fixed on the side wall of the main body 16.1 that contacts the material. Under the action of the buffer layer 16.2, part of the impact force of the material is absorbed, and the flow rate of the material is slowed down.
[0035] The specific operation process of this embodiment is as follows:
[0036] The material is discharged downward through the discharge pipe 1. After passing through the vibrating feeder 2, the material is sent to the rotary joint 5 through the discharge pipe 3 and the bend pipe 4. With the cooperation of the support plate 6, pulley 7 and annular slide rail 8, the rotary joint 5 is driven to rotate along the feed port of the electric arc furnace 9 by manually rotating the rotating rod 10. The rotation of the rotary joint 5 drives the chute 11 to rotate, realizing the left and right rotation of the chute 11 to distribute the material, thus expanding the distribution range.
[0037] During the rotation of the chute 11 by the rotary joint 5, the repeated extension and retraction of the telescopic device 12.3 of the chute up and down adjustment device 12 drives the first connecting rod 12.1 and the second connecting rod 12.2 to move, further driving the chute 11 to rotate up and down, reducing the labor intensity of the operators and achieving uniform material distribution in the electric arc furnace 9.
