Abstract
The present invention relates to a kind of chute air discharge structure,Particularly relate to a kind of aluminum electrolysis cell upper part alumina transferring chute efficiently, the air discharge structure of transporting chute on the groove of energy-saving and environmental protection.The air discharge structure of transporting chute on groove, chute fumer connects chute exhaust duct, hopper connects hopper exhaust duct, chute exhaust duct and hopper exhaust duct and accesses in flue cavity, set deashing pipe in flue cavity.Advantages of the present invention effect: use the present invention can realize the ventilation and negative pressure ventilation of transporting chute on groove, effectively solve the aluminium oxide of transporting chute and hopper on groove and fly upward problem, prevent dust accumulation in gas collection flue, reduce the conveyance loss of alumina raw material, improve potroom working environment.
Description
Technical field
The present invention relates to a kind of chute air discharge structure,Particularly relate to a kind of aluminum electrolysis cell upper part alumina transferring chute efficiently,
The air discharge structure of transporting chute on the groove of energy-saving and environmental protection.
Background technology
Aluminium oxide needed for aluminium cell produces typically passes sequentially through in ultra-dense phase and chute conveying addition groove feeding box, but this system uses the mode of gas positive pressure conveying, on groove, the exhaust effect of chute fumer is bad, make during in blanking process, substantial amounts of gas pours in groove feeding box, hopper pressure at expulsion is caused to increase, and form dust accumulation in hopper aerofluxus sweeps along a large amount of aluminium oxide to enter electrolysis bath flue or on mulch, severe jamming flue gas collection effect, even bury beam steel claw and blast welding block, guide rod group temperature is caused to raise, and then affect its pressure drop and mechanical strength.If hopper is poorly sealed, aluminum oxide dust also can form thicker accumulation horizon on groove top, even fills the air whole potroom, is not only degrading operating environment, also result in wastage of material.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides the air discharge structure of transporting chute on a kind of groove, it is therefore an objective to effectively solve the dust from flying in chute conveying and blanking process and wastage of material problem.
In order to reach above-mentioned purpose, the present invention is achieved through the following technical solutions: the air discharge structure of transporting chute on groove, chute exhaust duct is connected on chute fumer, connect hopper exhaust duct, chute exhaust duct and hopper exhaust duct on hopper to access in flue cavity, in flue cavity, set deashing pipe.
Chute exhaust duct and hopper exhaust duct merge into an exhaust duct and access in flue.
Deashing pipe is fixed in flue by support.
Deashing pipe one end sets snap joint, connects compressed air, and the other end is closed.
The source of the gas of deashing pipe is the compressed air in potroom, pouring aluminium ladle tail gas or crust breaking cylinder tail gas.
Flue includes upper flue and lower flue.
Advantages of the present invention effect:
Use the present invention can realize the ventilation and negative pressure ventilation of transporting chute on groove, effectively solve the aluminium oxide of transporting chute and hopper on groove and fly upward problem, prevent dust accumulation in gas collection flue, reduce the conveyance loss of alumina raw material, improve potroom working environment.
