Specific implementation mode
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, the shaft side wall are included in the cross section of vertical direction
For the ring wall 1, the wall 2 that cross section in the vertical direction is "-" type and filler rotor 3 of C fonts, the C of the ring wall 1
Font opening is connected on the medial surface of the wall 2, and parallel 2 medial surface of the wall of axis of the filler rotor 3 is described
Filler rotor 3 is set in the wall 2 and can rotate in contrast, and the diameter of the filler rotor 3 is more than the wall 2
Thickness, part that the wall 2 is contacted with the filler rotor 3 is fitted close, one end of the filler rotor 3 be provided with
Its coaxial shaft 4, the shaft 4 penetrate the wall 2 and are connected with the motor output end being set to outside the shaft, institute
Stating filler rotor 3 can enclose rotatable around its axis, and the filler rotor 3 includes feeding liner 5 and feeding port 6, and the feeding port 6 sets
It is placed in 3 side of filler rotor, the feeding liner 5 is connected by the feeding port 6 with the external world, and the feeding port 6 exists
It is close with the filler rotor 3 that outside arc length A on the cross section of 3 axis of filler rotor is less than the wall 2
The part of cooperation is being formed by arc length B on the cross section of 3 axis of filler rotor, when the filler rotor 3
The feeding liner 5 can select to be connected with inside the electric arc furnaces or external world.
Said program is main scheme for implementing said method, and it is rotatable around its axis that motor-driven rotatable shaft drives filler rotor to enclose, as Fig. 1,
Shown in Fig. 2, Fig. 3, it when filler rotor 3 rotates, can select that feeding liner 5 is made with the inside of electric arc furnaces or with the external world to be connected
It is logical.When feeding liner 5 is connected with the external world, then transferring raw material enters feeding liner 5 by feeding port 6, with filler rotor 3
Rotation, feeding liner 5 with the external world partition and be connected inside electric arc furnaces, at this point, raw material passes through feeding port from feeding liner 5
6 enter inside electric arc furnaces, complete filler.As shown in Fig. 2, with the rotation of filler rotor 3, because feeding port 6 is perpendicular to institute
The outside arc length A stated on the cross section of 3 axis of filler rotor is less than the wall 2 and 3 close-fitting portion of the filler rotor
Divide and be formed by arc length B on the cross section of 3 axis of filler rotor, i.e., can not pass through with the external world inside electric arc furnaces
Feeding port 6 and be connected to, feeding liner 5 can only with electric arc furnaces inside or any one of the external world be interconnected, ensure that electric arc furnaces
Closure in smelting process reduces scattering and disappearing for heat.
In the above-described embodiment, the axis of filler rotor 3 can be parallel to horizontal plane or perpendicular to horizontal plane, still
When the axis of filler rotor 3 is perpendicular to horizontal plane, the raw material in feeding liner 5 is not easy to drop into electric arc furnaces inside.Institute
With preferably, in the present embodiment, the axis of the filler rotor 3 is parallel to horizontal plane, raw material is made to be easier from feeding
It is fallen in liner 5 and blanking operation is steady.
