Problems solved by technology

[0004] During production, a constant pressure device is usually added to the circuit to ensure the stability of the raw material processing process, but in actual use, it is difficult to control the amount of raw material passing through the electric field, and the graphite column of the positive electrode will be broken during use. Gradually shorten, so the actual power will fluctuate, it is difficult to guarantee the stability of the finished product quality

Embodiment 1

[0028] Such as figure 1 As shown, the driving part includes a driving motor 9 and a driving screw 10 that is transmission-connected to the driving motor 9, and a sliding block 11 is provided on the driving screw 10, and the sliding block 11 is fixedly connected to the cross bar. The driving part also includes a positioning rod 12 arranged parallel to the driving screw 10 , and a positioning hole 13 cooperating with the positioning rod 12 is also provided on the sliding block 11 .

Embodiment 2

[0030] Such as figure 2 As shown, the driving part includes a driving telescopic rod 14 and a push block 15 that is drivingly connected with the driving telescopic rod 14, and the push block 15 is fixedly connected with the cross bar.

[0031] During use, the power supply 16 supplies power to the upper and lower electrodes 4 through the positive electrode row 17 and the negative electrode row 18, and ensures the input voltage through the potentiostat 19, and the detector 6 transmits the current in the circuit to the controller 2, After the controller 2 calculates the actual power through the input voltage and current, it compares the actual power with the preset power. If the actual power exceeds or is lower than the preset power, it controls the drive motor 9 / drives the telescopic rod 14 to move, driving the cross bar and the upper part The electrode 3 moves up and down to adjust the distance between the upper electrode 3 and the lower electrode 4, so as to adjust the actual p...

Abstract

The invention discloses a vertical graphitization furnace power constant device, which comprises a furnace body, a controller, an upper electrode and a lower electrode, wherein a lifting device is arranged above the furnace body, and is connected with the upper electrode, a detector is arranged on the connecting circuit of the upper electrode and the lower electrode, the detector is electrically connected with the controller, and the controller is suitable for controlling a driving part. According to the invention, through the arrangement of the lifting device connected with the upper electrode, the detector and the controller, actual current of a connecting circuit can be detected through the detector and transmitted to the controller, and the controller calculates actual power through the input voltage, controls the lifting device to drive the upper electrode to move up and down, and adjusts the distance between the upper electrode and the lower electrode until the actual power is within a preset power interval, so that through continuous adjustment and adaptation, the constant power is ensured so as to ensure the stability of the quality of a finished product.

Description

technical field [0001] The invention relates to the technical field of graphite furnaces, in particular to a power constant device for a vertical graphitization furnace. Background technique [0002] Graphitized powder is mainly used as recarburizer in iron and steel metallurgy, cathode carbon block, prebaked anode and diamond products of non-ferrous metal electrolytic cells, and is a very important industrial material. [0003] The existing widely used graphitization furnace is a vertical graphite resistance furnace, which heats up the raw material through the positive and negative graphite blocks arranged up and down; the principle is that after the raw material passes through the electric field between the positive and negative electrodes, due to the resistance of the raw material itself , generates heat after electrification, and conducts high-temperature treatment of raw materials. [0004] During production, a constant pressure device is usually added to the circuit t...
