Degree, described wall is fitted close with the part of described filler rotor contact, and one end of described filler rotor is provided with and is coaxial therewith
Rotating shaft, described rotating shaft is connected with the motor output end being arranged at outside described shaft, and described filler rotor can be around its axis
Rotate, described filler rotor includes feeding inner bag and feeding port, described feeding port is arranged at described filler rotor side surface, described send
Material inner bag is connected with the external world by described feeding port, and described feeding port is on the cross section perpendicular to described filler rotor axis
Outside arc length A be less than described wall and the close-fitting part of described filler rotor perpendicular to described filler rotor axis
Arc length B being formed on cross section, when described filler rotor described feeding inner bag can select internal with described electric arc furnace or
The external world is connected.
Further, the diameter parallel of described filler rotor is in horizontal plane.
Further, be also provided at the inclusion feed cylinder outside shaft, the downward-sloping port of export of described feed cylinder with described
The side of filler rotor is connected.
The invention has the beneficial effects as follows：In the middle of filler process, cannot be in communication with the outside by feeding port inside electric arc furnace,
Reduce electric arc furnace in the middle of filler process heat scatter and disappear.

Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1, Figure 2 and shown in Fig. 3, including shaft side wall, described shaft side wall includes the cross section in vertical direction
Cross section for the ring wall 1 of C font, in the vertical direction is the wall 2 of yi word pattern and filler rotor 3, the C of described ring wall 1
Font opening is connected on the medial surface of described wall 2, and described in the diameter parallel of described filler rotor 3, wall 2 medial surface, described
Filler rotor 3 is arranged in described wall 2 and can rotate in contrast, described filler rotor 3 with diameter greater than described wall 2
Thickness, part that described wall 2 is contacted with described filler rotor 3 is fitted close, one end of described filler rotor 3 be provided with
Its coaxial rotating shaft 4, described rotating shaft 4 is penetrated described wall 2 and is connected with the motor output end being arranged at outside described shaft, institute
State filler rotor 3 and can enclose rotatable around its axis, described filler rotor 3 includes feeding inner bag 5 and feeding port 6, and described feeding port 6 sets
It is placed in described filler rotor 3 side, described feeding inner bag 5 is connected with the external world by described feeding port 6, and described feeding port 6 exists
It is tight with described filler rotor 3 that outside arc length A on the cross section of described filler rotor 3 axis is less than described wall 2
Arc length B that the part of cooperation is formed on the cross section perpendicular to described filler rotor 3 axis, when described filler rotor 3
Described feeding inner bag 5 can select internal with described electric arc furnace or the external world is connected.
Such scheme is main scheme for implementing said method, and it is rotatable around its axis that motor-driven rotatable shaft drives filler rotor to enclose, such as Fig. 1,
Shown in Fig. 2, Fig. 3, when filler rotor 3 rotates, can select to make feeding inner bag 5 be connected with the inside of electric arc furnace or with the external world
Logical.When feeding inner bag 5 is connected with the external world, then transferring raw material enters feeding inner bag 5 by feeding port 6, with filler rotor 3
Rotation, feeding inner bag 5 and extraneous cut-off and be connected with inside electric arc furnace, now, raw material passes through feeding port from feeding inner bag 5
6 enter inside electric arc furnace, complete filler.As shown in Fig. 2 with the rotation of filler rotor 3, because feeding port 6 is perpendicular to institute
