Abstract
The present invention discloses a cathode impregnation method and a device. Firstly, a calcined cathode is delivered to a preheating furnace for preheating, so the cathode is from 260 to 320 DEG C; then, the preheated cathode is delivered to a high pressure dip tank, and is pressurized in the high pressure dip tank for 5 to 15 minutes at the high atmospheric pressure of 0.5MPa; next, the preheated cathode is pressurized for 3 to 5 hours by 1 to 2MPa of Nitrogen (N2), and fused asphalt is pressed and filled into air holes in the cathode by high pressure gas. The device is characterized in that the device comprises the preheating furnace, the high pressure dip tank, a stock pusher in front of the preheating furnace and a basket changing machine at the rear side of the preheating furnace; tracks are paved from the basket changing machine to the front of the high pressure dip tank, a cathode delivery wagon is arranged on the tracks, and a fixed type track machine is also in front of the high pressure dip tank. Because of the technology, the calcined cathode is used for machining of electrolytic aluminum after the cathode is dipped. Thus, the quality of the cathode is greatly enhanced, and the quality and the production efficiency of the electrolytic aluminum completed product are indirectly enhanced.
Description
Technical field:
The present invention relates to a kind of dipping working method and device of electrolgtic aluminium negative electrode.
Background technology:
In the prior art, the negative electrode that all electrolytic aluminium factories are used is directly used in production after being roasting.Can form some pores owing to negative electrode after the roasting is inner and make the negative electrode poor quality, when Aluminum Electrolysis Production, can have a strong impact on the quality of aluminium finished product like this, make that simultaneously the efficient of electrolytic aluminum is not high, consume a large amount of electric energy.
Summary of the invention:
The objective of the invention is to: a kind of cathode impregnation method is provided, utilizes pitch to be full of the pore of negative electrode inside, improve its quality, improve the quality and the production efficiency of electrolytic aluminum finished product indirectly.
Another object of the present invention is to: a kind of cathode impregnating device is provided, can produces better negative electrode, to improve the quality and the production efficiency of electrolytic aluminum finished product.
The present invention is achieved in that method of the present invention: earlier the negative electrode after the roasting was delivered in the preheating oven 1 preheating 5～7 hours, make negative electrode reach 260～320 ℃, then that preheating is good negative electrode is sent into high-pressure impregnation jar 2, with the air pressurized of 0.5MPa 5～15 minutes, use the nitrogen N of 1～2MPa in 2 li in high-pressure impregnation jar again
2Pressurizeed 3～5 hours, and utilized high pressure gas that fused pitch is pressed into and be full of in the pore of negative electrode inside.
Structure of the present invention: it comprises preheating oven 1 and high-pressure impregnation jar 2, be provided with pushing device 3 in preheating oven 1 front, the back of preheating oven 1 is provided with basket replacing device 4, and basket replacing device 4 is covered with track 7 to high pressure impregnating autoclave 2, be provided with negative electrode waggon 5 above, before high-pressure impregnation jar 2, be provided with fixed track machine 6.
In order to enhance productivity, the burner hearth of preheating oven 1 can be placed three preheating baskets 8; Track 7 is connected with two cover high-pressure impregnation jar 2 and fixed track machines 6.
Owing to adopted above-mentioned technology, the negative electrode after the roasting is used further in the processing of electrolytic aluminum after flooding, the quality of negative electrode itself is improved greatly, improved the quality and the production efficiency of electrolytic aluminum finished product indirectly, the electric energy that has been consumed when having reduced electrolytic aluminum simultaneously.
Description of drawings:
Accompanying drawing 1 is a schematic top plan view of the present invention.
Embodiment:
Embodiments of the invention: the burner hearth of the preheating oven 1 that adopts among the present invention three baskets of negative electrodes of can packing into. preheating oven 1 front installs one
Platform pushing device 3, the preheating basket 8 that installs negative electrode is pushed in the preheating oven 1, basket replacing device 4 is installed in back at preheating oven 1, basket replacing device 4 is laid track 7 before high-pressure impregnation jar 2, a negative electrode waggon 5 is installed on the track 7, in order to increase work efficiency, two high-pressure impregnation jars 2 can be installed side by side, before every high-pressure impregnation jar 2 a fixed track machine 6 is installed.The preheating basket 8 that pushing device 3 will install negative electrode pushes in the preheating oven 1, a preheating basket 8 is arrived preheating oven 1 back by pushing tow in the preheating oven 1 simultaneously, basket replacing device 4 was placed on the negative electrode in the preheating basket 8 and was arranged in dipping baskets 9 on the negative electrode waggon 5 this moment, before negative electrode waggon 5 is delivered to high-pressure impregnation jar 2 with dipping baskets 9 then, by fixed track machine 6 dipping baskets 9 is pushed high-pressure impregnation jar 2 and flood processing.
