A graphite electrode heating device

Abstract

The invention discloses a graphite electrode heating device which comprises a box body and a motor arranged on one side of the box body. A groove is formed in one side of the box body, and a rotatinghole is formed in the inner wall of the side, close to the motor, of the groove. A rotating shaft is welded on an output shaft of the motor, one end of the rotating shaft penetrates through the rotating hole and extends into the groove, and a sleeve is welded on the end of the rotating shaft. A first belt pulley is fixedly sleeved on the outer side of the rotating shaft. Stand columns are welded on the inner wall of the top side and the inner wall of the bottom side of the groove, and circular columns are horizontally and rotationally arranged on the ends, close to each other, of the two standcolumns. Second belt pulleys are fixedly sleeved on the outer sides of the circular columns, and a same belt is arranged on the two second belt pulleys and the first belt pulley in a transmitting mode. The graphite electrode heating device has the advantages of reasonable design and high practicability and is convenient to drive a sleeve to rotate. Moreover, the flow intensity of air in the groove can be increased through a fan blade, so that a graphite electrode in an electrode placing slot can be fully in contact with the air in the groove, and the temperature rising rate of the graphite electrode is increased.

Description

technical field [0001] The invention relates to the technical field of graphite electrode heating equipment, in particular to a graphite electrode heating device. Background technique [0002] In the production of smelting furnaces, heating devices with graphite electrodes are usually used for heating. After retrieval, the patent document with application number 201721596344.9 discloses a graphite electrode heater, including a main box and a drive motor, the drive motor is fixedly connected to one side of the main box, and the output end of the drive motor is fixedly connected There is a rotating rod. The end of the rotating rod away from the drive motor penetrates the outer wall of the main box and extends inward. The extended end of the rotating rod is rotatably connected with the inner wall of the main box. The rotating rod is fixedly sleeved with a mounting The mounting block is surrounded by a plurality of cavities, one end of the inner wall of the cavity is provided w...

AI Technical Summary

Problems solved by technology

[0003] The graphite electrode heater of the above design can fully heat the electrode when the device is heating the electrode through the setting of the rotating rod and the mounting block, thereby improving the heating efficiency of the device, but the above design still has shortcomings, the above design It is inconvenient to increase the air flow rate inside the box, so that the graphite electrode cannot fully contact with the hot air inside the box, and the heating rate of the graphite electrode is low, so we propose a graphite electrode heating device to solve the above problems
