Slag adding device of electroslag furnace

Abstract

The utility model relates to the technical field of electroslag furnaces, and discloses an electroslag furnace slag adding device which comprises a support, a top plate, a conical stock bin, a rotating shaft, a spiral blade, a conical plug, an auger conveyor, a telescopic pipe and a weight sensor. During use, the rotating shaft is driven by external force to do linear motion, the conical plug can be driven to move, and therefore the conical plug opens or closes the discharging opening of the conical stock bin. When the conical plug opens the discharging opening, the rotating shaft rotates, and then the spiral blade can be driven to rotate. Therefore, the materials in the conical stock bin are pushed to move and are continuously discharged from the discharging opening. When the rotating shaft stops rotating, the spiral blade can stop conveying the materials. And then, the conical plug closes the discharging opening, so that the materials in the conical material bin can be prevented from leaking out. Due to the fact that the weight sensor can weigh the weight of the materials in the conical stock bin in real time, the discharging amount can be calculated according to the weight difference. Therefore, quantitative discharging is achieved, and the purpose of conveying materials with preset weight is achieved.

[0018] The electric slag furnace slag feeding device provided by the embodiments of the present disclosure comprises a support, a top plate, a conical bin, a rotating shaft, a spiral blade, a conical plug, a conveyor, an extension tube and a weight sensor. The top plate is located above the support in the height direction of the support and is used to support and mount the conical bin. The conical bin is connected to the bottom surface of the top plate in the height direction of the support and is used to contain materials. The rotating shaft is located in the interior of the conical bin and is coaxially distributed with the conical bin and is used to support and mount the spiral blade and the conical plug. The spiral blade is mounted on the rotating shaft and is located in the discharge port of the conical bin and is used to push the materials to move. The conical plug is mounted at the bottom end of the rotating shaft and is used to open or close the discharge port of the conical bin. The conveyor is located below the conical bin in the height direction of the support and is used to convey the materials to the electric slag furnace.

When the conical plug opens the discharge port, the rotating shaft is driven by an external force to perform rotational motion, thereby driving the spiral blade to rotate. Thus, the materials in the conical bin are pushed to move and continuously discharged from the discharge port. When the rotating shaft is stopped by an external force, the spiral blade stops conveying the materials. Then, the conical plug closes the discharge port, thereby preventing the materials in the conical bin from leaking out. Since the weight sensor can measure the weight of the materials in the conical bin in real time, the weight difference can be used to calculate the discharge amount. Thus, the materials can be discharged quantitatively, and the purpose of conveying the materials with a preset weight is achieved.

[0035] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0036] In combination with Figures 1 to 4As shown, the electric slag furnace feeding device provided by the embodiment of the present disclosure comprises a support 1, a top plate 2, a conical bin, a rotating shaft 4, a spiral blade 5, a conical plug 6, a dragon conveyor 7, an extendable pipe 8 and a weight sensor 9. The top plate 2 is above the support 1 along the height direction of the support 1 and is used to support the conical bin 3. The conical bin is connected to the bottom surface of the top plate 2 along the height direction of the support 1 and is used to contain materials. The rotating shaft 4 is inside the conical bin 3 and is coaxial with the conical bin 3 and is used to support the spiral blade 5 and the conical plug 6. The spiral blade 5 is installed on the rotating shaft 4 and is inside the discharge port of the conical bin and is used to push the materials to move. The conical plug 6 is installed at the bottom end of the rotating shaft 4 and is used to open or close the discharge port of the conical bin 3. The dragon conveyor 7 is below the conical bin along the height direction of the support 1 and is used to convey the materials to the electric slag furnace. The extendable pipe 8 is installed between the material receiving port of the dragon conveyor 7 and the discharge port of the conical bin 3 and is used to make the materials discharged from the material receiving port fall into the discharge port. In addition, the extendable pipe 8 can be stretched or compressed so as to avoid affecting the measurement results of the weight sensor 9. The weight sensor 9 is evenly installed between the support 1 and the top plate 2 along the height direction of the support 1 and is used to measure the weight of the materials in the conical bin 3. The rotating shaft 4 is controlled to make rotational motion and linear motion so as to drive the spiral blade 5 to rotate and the conical plug 6 to move.

[0037] The electric slag furnace feeding device provided by the embodiment of the present disclosure can make the rotating shaft 4 make linear motion under the driving of an external force, that is, can drive the conical plug 6 to move, so as to make the conical plug 6 open or close the discharge port of the conical bin 3. When the conical plug 6 opens the discharge port, the rotating shaft 4 can make rotational motion under the driving of an external force, that is, can drive the spiral blade 5 to rotate. Thus, the materials in the conical bin 3 are pushed to move and continuously discharged from the discharge port. The rotating shaft 4 can stop rotating under the driving of an external force, and the spiral blade can pause conveying the materials. Then, the conical plug 6 closes the discharge port, so as to prevent the materials in the conical bin 3 from leaking out. Since the weight sensor 9 can weigh the weight of the materials in the conical bin 3 in real time, the weight difference can be calculated, so as to calculate the discharge amount. Thus, the quantitative discharge is realized, and the purpose of conveying the materials with a preset weight is achieved.
