A high-efficiency impregnation device for graphite electrodes

Abstract

The invention provides a high-efficiency impregnation device for a graphite electrode. The high-efficiency impregnation device comprises a base; a horizontal mounting plate is arranged at the upper side of the base; a front-back support plate is arranged at the middle of the bottom of the mounting plate; the left and right ends of the mounting pate are each hinged with the base through a first hydraulic rod; a front-rear semicircular pipe body is fixedly installed at the upper side of the mounting plate; the front end, the rear end and the upper side of the semicircular pipe body are each opened; and the front and rear ends of the semicircular pipe body are each provided with a semicircular cover. When the high-efficiency impregnation device provided by the invention is in use, the graphite electrode slowly moves toward the semicircular pipe body with a feeding conveying belt; a horizontal shaft moves under the driving of a first motor; the movement of a second slider cooperates with aseries of actions such as stretch and contraction of a multi-stage hydraulic rod and a first electric telescopic rod to realize uninterrupted automatic dipping work of a plurality of group of graphite electrodes; a worker needs not to get close to the graphite electrodes during the overall process; and a clamping protective part can be repeatedly used in a dipping process of different groups of graphite electrodes, thereby greatly improving the dipping efficiency, improving the work safety and realizing automatic dipping.

Description

technical field [0001] The invention belongs to the technical field of graphite electrode production, in particular to a high-efficiency impregnation device for graphite electrodes. Background technique [0002] The raw product of graphite electrode after compression molding has very low porosity, but after the product is roasted, part of the coal tar pitch decomposes into gas and escapes during the roasting process, and the other part is coked into pitch coke, and the volume of the generated pitch coke is much smaller than that of coal. Although the volume originally occupied by asphalt shrinks slightly during the roasting process, many irregular tiny pores with different pore sizes are still formed inside the product. The existence of a large number of pores will inevitably have a certain impact on the physical and chemical properties of the product. , impregnation is a process that reduces the porosity of the product, increases the density, increases the compressive stren...

[0002] The raw product of graphite electrode after compression molding has very low porosity, but after the product is roasted, part of the coal tar pitch decomposes into gas and escapes during the roasting process, and the other part is coked into pitch coke, and the volume of the generated pitch coke is much smaller than that of coal. Although the volume originally occupied by asphalt shrinks slightly during the roasting process, many irregular tiny pores with different pore sizes are still formed inside the product. The existence of a large number of pores will inevitably have a certain impact on the physical and chemical properties of the product. , impregnation is a process that reduces the porosity of the product, increases the density, increases the compressive strength, reduces the resistivity of the finished product, and changes the physical and chemical properties of the product. However, the existing impregnation device is difficult to automate, and multiple graphite electrodes are often stacked In the container, it is difficult to realize the impregnation treatment at the position where the graphite electrodes are in contact with each other. The solution does not have the function of automatic stirring, and the impregnation efficiency is low. The existing technology is difficult to realize automatic impregnation production. damage etc.
