Abstract
The present invention relates to a kind of electrolytic bath feed box structures, more particularly to a kind of electrolytic bath feed box structure using high-temperature flue gas preheating material, including hopper and smoke pipe, hopper is equipped with feed pipe and discharge nozzle, it is slot upper flue above hopper, it is horizontal cover plate below hopper, smoke pipe is pierced by from horizontal cover plate, and the inside by hopper or the side wall as hopper enter slot upper flue.The heat that the raw materials such as alumina particle absorb in electrolyte melt course of dissolution can be effectively reduced, solution rate is accelerated and improves solute effect, reduces to the thermally equilibrated interference of electrolytic cell, improves the thermally equilibrated stability of electrolytic cell.
Description
Technical field
The present invention relates to a kind of electrolytic bath feed box structure more particularly to a kind of electrolytic cells using high-temperature flue gas preheating material
Bin structure, it is therefore an objective to the materials such as aluminium oxide and the aluminum fluoride in heating tank feeding box are realized using high-temperature flue gas in electrolytic cell.
Background technique
During aluminum electrolysis, the particles such as aluminium oxide, aluminum fluoride and electrolyte need timing that height is added as raw material
In warm electrolyte melt.The temperature of feed particles is typically slightly above room temperature in hopper, about between 20~50 DEG C, and high-temperature electric
Solving matter melt is then between 910~970 DEG C.The raw material of cold conditions, which is added in high-temperature electrolysis matter, needs to absorb a large amount of heat, ability
It is gradually dissolved in melt, therefore larger to the thermal balance interference near blanking point, since partial electrolysis matter melt temperature reduces,
Cause the degree of superheat to reduce, so that aluminium oxide cannot sufficiently dissolve in time and sink to cathode surface and become to precipitate, and then is easy to cause
The abnormal phenomenon such as electrolytic cell precipitating increases, hearth and bottom rises.
In traditional pot superstructure, slot upper flue and alumina reservoir, fluoride salt bin etc. are mutually indepedent.And slot
Upper exhaust gas temperature is up to 120~200 DEG C, and flow is larger, is directly discharged into purification system by slot upper flue, causes serious
Energy dissipation.
Summary of the invention
In order to solve the above technical problem, the present invention provides a kind of electrolytic bath feed box knots using high-temperature flue gas preheating material
Structure, it is therefore an objective to preheat the feed particles such as the aluminium oxide in hopper using big flow high-temperature flue gas, dissolve it in electrolyte melt
During the heat that absorbs reduce, and then reduce to the thermally equilibrated interference of electrolytic cell, improve the thermally equilibrated stability of electrolytic cell.
A kind of electrolytic bath feed box structure using high-temperature flue gas preheating material of the invention for the above-mentioned purpose, including hopper and
Smoke pipe, it is characterised in that hopper is equipped with feed pipe and discharge nozzle, is slot upper flue above hopper, is horizontal cover below hopper
Plate, smoke pipe are pierced by from horizontal cover plate, and the inside by hopper or the side wall as hopper enter slot upper flue.
The feed pipe is located at the top of hopper, and discharge nozzle is located at the bottom of hopper.
Described is equipped with baffle on the inner wall of hopper top surface.
When the smoke pipe is passed through inside hopper, the quantity of smoke pipe is 1-20 root.
When side wall of the smoke pipe as hopper, the quantity of smoke pipe is 1-20 root.
The top of the hopper is equipped with air-exhausting duct, and the other end of air-exhausting duct is connected to smoke pipe.
Advantages of the present invention effect: the present invention preheats the raw materials such as the aluminium oxide in hopper using big flow high-temperature flue gas
Grain, the heat for absorbing it during the dissolution of electrolyte melt reduces, and then reduces to the thermally equilibrated interference of electrolytic cell, mentions
The high thermally equilibrated stability of electrolytic cell.
