[0036] In order to reduce the length of the chute, thereby reducing the chute sticking iron, improving the metal recovery rate and reducing the production cost, an electric furnace wall iron mixing device 200 is provided in the application, Figure 1 The structure schematic view of the electric furnace wall iron mixing device in the embodiment of the utility model is not turned over, Figure 2 The structure schematic view of the electric furnace wall iron mixing device in the embodiment of the utility model is turned over, Figure 3 The top view schematic view of the electric furnace wall iron mixing device in the electric furnace wall iron mixing system in the embodiment of the utility model under two positions before and after rotating, as shown in Figures 1 to 3 The electric furnace wall iron mixing device 200 can include: a base 2; a rotating drive mechanism 1 connected with the base 2, the rotating drive mechanism 1 can drive the base 2 to rotate around the first axis; a tilting rack 3 arranged on the base 2, the tilting rack 3 is rotationally connected with the base 2, and the tilting rack 3 is used for installing a ladle 4; a tilting rack drive mechanism 5, which is used for driving the tilting rack 3 to rotate around the rotation connection between the tilting rack 3 and the base 2; a first chute 6 mounted on the base 2, when the tilting rack drive mechanism 5 drives the tilting rack 3 to rotate around the rotation connection between the tilting rack 3 and the base 2, the molten iron in the ladle 4 can be poured into the first chute 6.

[0037] An electric furnace wall iron mixing system is also provided in the application, as shown in Figure 3 The electric furnace wall iron mixing system can include: an electric furnace wall iron mixing device 200; an electric furnace 100, including a furnace body with a containing cavity and a second chute 101 for guiding fluid into the containing cavity; the first chute 6 can correspond to the second chute 101, so that the fluid in the first chute 6 flows into the upper.

[0038] The electric furnace wall iron mixing device 200 in the application can drive the base 2 to rotate around the first axis by the rotary driving mechanism 1, so that the ladle 4 and the first chute 6 installed on the tilting frame 3 on the base 2 rotate greatly, so that the first chute 6 can be aligned with the second chute 101 of the electric furnace 100, and the molten iron in the ladle 4 flows into the first chute 6 and then enters the furnace body of the electric furnace 100 through the second chute 101. Through the above process, the length of the first chute 6 can be effectively reduced, and alignment with the second chute 101 of the electric furnace 100 can also be achieved, so that the first chute 6 can be reduced, thereby improving the metal recovery rate and reducing the production cost.

[0039] As shown in Figures 1 to 3 , the base 2 can include a base 21 with wheels 22, a support mechanism 23 extending in the vertical direction mounted on the base 21, and a tilting frame 3 rotatably connected to the upper end of the support mechanism 23. The rotation line of the tilting frame 3 and the support mechanism 23 can extend in the horizontal direction. The lower end of the base 21 is in contact with the ground through the wheels 22, and the rotary driving mechanism 1 can drive the base 2 to rotate around the first axis through the wheels 22. The first axis can extend in the vertical direction. The rotary driving mechanism 1 can be a hydraulic drive or a motor drive, which includes a rotating shaft connected to the base 2, and the rotating shaft is driven to rotate by the hydraulic drive or the motor drive, and the rotating shaft drives the base 2 to rotate. The related parts of the hydraulic drive or the motor drive are fixed to the ground.

[0040] As shown in Figures 1 to 2 , the tilting frame driving mechanism 5 can include a first hydraulic cylinder extension mechanism 51, the extension end of the first hydraulic cylinder extension mechanism 51 is hinged to the tilting frame 3, and the support end of the first hydraulic cylinder extension mechanism 51 is hinged to the base 21. By extending the first hydraulic cylinder extension mechanism 51, the tilting frame 3 can drive the ladle 4 to overturn together, realize the tilting action of the ladle 4, so that the molten iron in the ladle 4 is poured out through the outlet of the ladle 4.

[0041] As shown in Figures 1 to 3As shown, the first chute 6 is rotatably connected with the support mechanism 23, so that the first chute 6 can rotate around the rotatable connection of itself to change the height of the outlet of the first chute 6. As a possibility, the rotatable connection of the first chute 6 with the support mechanism 23 and the rotatable connection of the tilting platform 3 with the support mechanism 23 can be the same. That is, the rotation of the first chute 6 and the tilting platform 3 can be realized by using the same rotation shaft. The electric furnace wall iron feeding device 200 can include a first chute driving mechanism 8 for driving the first chute 6 to rotate around the rotatable connection of itself. Further, the first chute driving mechanism 8 can include a second hydraulic cylinder telescopic mechanism 81, the extending end of which is hinged with the first chute 6, and the supporting end of which is hinged with the base 2. The first chute 6 can be jacked up by the first chute driving mechanism 8. Since the electric furnace 100 needs to be tilted for tapping or slagging for each furnace, and the second chute 101 is fixed on the wall of the electric furnace 100, in order to avoid collision between the first chute 6 and the second chute 101 during the tilting of the electric furnace 100, the first chute 6 can be lifted a certain distance under the action of the first chute driving mechanism 8, so that collision can be avoided during the tilting of the electric furnace 100.

[0042] The tilting angle of the ladle 4 can generally reach about 90°. In order to prevent the ladle 4 from sliding off the tilting platform 3 when performing the tilting action, the tilting platform 3 is provided with a ladle locking mechanism 7, which can lock the ladle 4 with the tilting platform 3 when the ladle 4 is located on the tilting platform 3. As a possibility, the ladle 4 has a pin shaft. The ladle locking mechanism 7 can include a limiting hook 71 and a limiting hook driving mechanism 72 capable of driving the limiting hook 71 to rotate, under the action of the limiting hook driving mechanism 72, the limiting hook 71 can hook the pin shaft to lock the ladle 4 on the tilting platform 3.

[0043] The working process of the electric furnace wall iron mixing device 200 cooperating with the electric furnace 100 is as follows: the ladle 4 is moved and sat on the tilting frame 3 of the electric furnace wall iron mixing device 200 by the crane. The ladle 4 is locked with the tilting frame 3 through the ladle locking mechanism 7. The base 2 is driven to rotate around the first axis by the rotary drive mechanism 1, and the base 2 can rotate together with the tilting frame 3 and the ladle 4 on the base 2, so that the first chute 6 of the electric furnace wall iron mixing device 200 and the second chute 101 of the electric furnace 100 are aligned. Then, the first hydraulic cylinder telescopic mechanism 51 in the tilting frame driving mechanism 5 is extended to lift, and the ladle 4 and the tilting frame 3 are slowly lifted and rotated around the rotating connection, and the molten iron in the ladle 4 slowly flows into the first chute 6 from the outlet mixing spout of the ladle 4, then flows into the second chute 101, and finally enters the containing cavity in the furnace body of the electric furnace 100. After the electric furnace 100 is mixed with iron, the first hydraulic cylinder telescopic mechanism 51 in the tilting frame driving mechanism 5 is retracted, and the ladle 4 and the tilting frame 3 are slowly lowered and rotated around the rotating connection to return to the horizontal position. The ladle 4 is unlocked with the tilting frame 3 through the ladle locking mechanism 7. The electric furnace 100 is about to shake and tap, in order to avoid the collision between the first chute 6 and the second chute 101, the second hydraulic cylinder telescopic mechanism 81 in the first chute driving mechanism 8 is extended to lift the first chute 6 and rotate around the rotating connection, and then the electric furnace 100 shakes and taps. After the electric furnace 100 is tapped, the electric furnace 100 is returned to normal, and the second hydraulic cylinder telescopic mechanism 81 in the first chute driving mechanism 8 is retracted to lower the first chute 6, and the first chute 6 returns to the original position. After the molten iron in the whole ladle 4 is mixed, the base 2 with the tilting frame 3 and the ladle 4 is rotated by the rotary drive mechanism 1 to return to the original position. The empty ladle 4 is lifted away by the crane, and the full ladle 4 is moved and sat on the tilting frame 3, so as to perform the next operation cycle.

[0044] The electric furnace wall iron mixing device 200 in the application is mainly used for electric furnace 100 wall iron mixing, and the device is simple, compact, reliable and new, and the base 2 with the tilting frame 3 and the ladle 4 can be rotated together by the rotary drive mechanism 1, so that the length of the first chute 6 is greatly reduced, the first chute 6 can be aligned with the second chute 101 of the electric furnace 100, and the iron sticking in the chute can be reduced, the metal yield can be improved, and the production cost can be reduced.
