The invention discloses an electric heating forming nozzle for a carbon electrode extruder, and relates to the technical field of accessories of carbon electrode extruders, in particular to an internal and external split forming nozzle of a carbon electrode extruder with a temperature closed-loop control function. A nozzle core is a rotary body, the inner surface of the nozzle core is designed in a forming nozzle curve, and the nozzle core and a nozzle sleeve are assembled into a whole in a transition fit mode through a stepped structure; N through holes are evenly distributed in the nozzle sleeve around the center line in the circumferential direction, and a leakage protection device A and a leakage protection device B are arranged at installation openings in the two ends of each through hole respectively; mica tubes are arranged outside copper rods in a sleeving mode and are inserted into the through holes; two ends of each copper rod are respectively fixed in the corresponding leakage protection device A and the leakage protection device B through connecting plates and copper nuts; and an electric heater is of an annular structure and is installed at a right end opening of the nozzle sleeve. According to the technical scheme, the problems that in the prior art, the inner wall of a forming nozzle is abraded quickly, the replacement cost is high, heat-conducting oil is easy to leak, potential safety hazards are prone to occurring, and no temperature control measure is taken at an outlet of the forming nozzle, so that the product quality is poor are solved.
Description
technical field [0001] The invention relates to an electric heating nozzle for a carbon electrode extruder, and relates to the technical field of accessories for a carbon electrode extruder, in particular to an inner and outer split nozzle of a carbon electrode extruder with closed-loop temperature control. Background technique [0002] The nozzle of the carbon electrode extruder belongs to the core component of the carbon electrode extruder. The nozzle is installed on the outlet side of the material chamber device of the extruder. The deformation of the paste occurs in the compression zone on the inner surface of the nozzle. The material passes through the nozzle, and after being extruded and deformed, it becomes an electrode product that meets the requirements. Therefore, the nozzle has a great influence on the quality of the electrode product. Especially the temperature control of the nozzle, through the temperature sensor temperature measurement and PLC program control, ...
