Automatic feeding, traction operation and discharging system for graphite electrode paste

Abstract

The invention discloses an automatic graphite electrode paste feeding, traction operation and discharging system which is characterized in that a hopper for containing graphite paste is conveyed to asecond-layer platform from a first-layer platform and poured into a cooling machine; the conveying line comprises a first-layer conveying line body, a lifting rotating platform, a lifting conveying device and a second-layer conveying line body. Paste poured from a kneading pot is received by the hopper, the hopper is pushed to the lifting rotary platform through the first-layer traction head, thehopper rotates by 180 degrees to be separated from the first-layer traction head, the lifting rotary platform is conveyed to the second-layer platform through the lifting conveying device, and the hopper is pulled to the position above the material cooling machine through the second-layer traction head so that the hopper can be separated for discharging. Then, the operation is reversely repeated to finish one-time feeding; according to the invention, the probability of man-made mistakes is reduced, the safety coefficient is increased, the scattering of the paste is avoided, and the purity of the paste and the product quality are ensured.

Description

technical field [0001] The invention relates to a transportation device and a wire body for graphite electrode preparation, and more specifically relates to a graphite electrode paste automatic feeding, traction operation and unloading system. Background technique [0002] Graphite electrodes are mainly made of petroleum coke and needle coke, and coal tar pitch is used as a binder. They are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. They are released in the form of arcs in electric arc furnaces. Conductors that are heated and melted by electric energy can be divided into ordinary power, high power and ultra-high power according to their quality indicators. [0003] The existing graphite electrode preparation methods basically use the graphite electrode paste poured out of the kneading pot to be transported by driving or belt: the driving loading is to lift the paste hopper to a certain height and then move it left and right, a...

Problems solved by technology

[0003] The existing graphite electrode preparation methods basically use the graphite electrode paste poured out of the kneading pot to be transported by driving or belt: the driving loading is to lift the paste hopper to a certain height and then move it left and right, and then put the paste hopper Turning over and unloading, although the overall transportation efficiency is high, the operation is troublesome, the safety factor is low, the probability of human error is high, and the smoke cannot be collected

Belt transmission is to convey the paste to the discharge port through the belt, and the paste will automatically fall into the cooling machine. Although this method has a simple structure and is easy to control, it has low efficiency and the paste is easy to spill during the belt feeding process. , the belt frequently transports the paste for a long time, it is easy to age and fall off, which affects the purity and product quality of the product paste
