Lengthwise graphitization furnace power transmission trolley backstepping power shutoff system

Abstract

The invention belongs to the technical field of lengthwise graphitization furnace control and particularly relates to a lengthwise graphitization furnace power transmission trolley backstepping powershutoff system. The system comprises an oil cylinder support base, wherein the oil cylinder support base is connected with four bidirectional oil cylinders, and the left and right sides of each bidirectional oil cylinder are connected with a left limiting column and a right limiting column respectively. Each left limiting column is in matched connection with a left connecting base, each left connecting base is provided with a left movable hole and connected with a left connecting plate, and each left connecting plate is connected with a front copper plate; each right limiting column is in matched connection with a right connecting base, each right connecting base is provided with a right movable hole, each right connecting base is connected with a right connecting plate, and each right connecting plate is connected with a rear copper plate; the oil cylinder support base is fixedly connected with two oil cylinders, the right connecting plates are provided with through holes matched withthe two oil cylinders, the through holes run through the front copper plates, and both the bidirectional oil cylinders and the oil cylinders are connected with a hydraulic station.

Description

technical field [0001] The invention belongs to the technical field of control of graphitized internal series furnaces, and in particular relates to a reverse inference power-breaking system of a graphitized internal series furnace power transmission trolley. Background technique [0002] The series furnace in the graphitization furnace is a resistance furnace equipment for the production of ultra-high-power graphite electrodes. The products in the furnace are roasted by connecting the copper and aluminum conductive bars in series through the power transmission trolley. After the high current is energized, the products in the furnace are used The electric resistance converts electric energy into heat energy, and graphitizes the products in the furnace; the power transmission trolley is a series of conductive equipment connected to the graphitization furnace on the left and right sides, and the hydraulic system is used to control the expansion and contraction of the copper sof...

AI Technical Summary

Problems solved by technology

[0003] The current design of graphitized electrode internal series furnaces is designed to transmit power to two furnaces when the current is low in the early stage, and to change to a single furnace when the current is high in the later period to impact the peak, and the state of single furnace power transmission does not need to be pressurized; the existing technology is in The old method is used when the power is transmitted to a single furnace. The power transmission trolley is retracted to cut off the power, so that the pressure of the furnace will be released, the electrode of the furnace head will be disconnected from the conductive copper plate, and the products in the furnace will be loosened. Phenomena such as entry into the filler, breakage of the intermediate graphite pad, etc., causing unnecessary losses
