Technical field
Patent one flue automatic ash removing device of the present invention, particularly relates to a kind of aluminum electrolyzing cell used crust-breaking & baiting system tail gas and realizes gas collection flue aluminium cell flue automatic ash removing device.
Background technology
Aluminium cell typically can run into two difficult problems during production run, and one is that the dust accumulation in gas collection flue is difficult to clear up, and two are how crust-breaking & baiting system processes with compressed-air actuated tail gas.
No matter electrolysis bath uses upper flue gas-collecting structure or lower flue gas-collecting structure, always one inevitable problem of the dust stratification in flue, and have a strong impact on the gas collection effect of flue.Some aluminium manufacturer takes the mode periodically purged by the compressed air of potroom to clean flues dust stratification, but often brings Railway Project, one be must labor cleaning, workload is huge and repeats at periodic or other desired；Two is to be switched on cell cover plate, and aluminum oxide dust flies upward seriously, and significant loss is serious, and reduces electrolysis bath gas collecting efficiency, is degrading the operating environment of potroom.
Upper part of the electrolytic cell has many set crust-breaking & baiting systems, has been necessary for a crust-breaking & baiting process every few minutes.Wherein cylinder is the core component frequently used, and needs compressed air to be controlled, and after the reciprocating motion completing a cycle, controls gas circuit and is discharged by waste gas.Traditional way is directly to be emptied by waste gas, produces bigger noise pollution, disturbs normal good hearing and the routine work of electrolysis work, is degrading the working environment of potroom.Tail gas is directly accessed in flue by some aluminium manufacturer, or along journey collection tail gas and enters in flue with a thicker steel pipe, solves noise problem, but causes energy waste.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of aluminium cell flue automatic ash removing device, it is therefore an objective to solve the problem that dust deposit in flue cleaning work amount is big and crust-breaking & baiting system tail gas effectively utilizes.
In order to reach above-mentioned purpose, the present invention is achieved through the following technical solutions: aluminium cell flue automatic ash removing device, and the steam vent including crust breaking cylinder and constant-volume blanking device, crust breaking cylinder and constant-volume blanking device is connected with the deashing pipe being located in flue by flexible pipe respectively.
Deashing pipe is provided with injection tube.
Deashing pipe enters the end of ash end and is provided with flaring drain oviduct.
Being provided with drain straight tube in drain oviduct, one end of drain straight tube is inserted in drain oviduct, and flexible pipe is inserted in the other end of drain straight tube.
Flue includes upper flue and lower flue.
The caliber scope 10～100mm of drain straight tube, length range 30～300mm.
The caliber scope of the upper and lower mouth of drain oviduct is respectively 40～300mm, 20～200mm, altitude range 30～300mm.
Drain straight tube is wound around by iron wire or is weldingly fixed on drain oviduct.
Drain oviduct is connected for welding or bolt with deashing pipe.
Deashing pipe caliber scope is 20～200mm.
Injection tube caliber scope is 10～100mm.
On every deashing pipe, the injection tube quantity of welding is 2～20.
Advantages of the present invention effect:
The present invention is used can effectively to utilize crust-breaking & baiting system tail gas, realize gas collection flue automatic ash removing, improve energy utilization rate, flue gas collection effect and electrolysis bath airtight efficiency have been effectively ensured, thoroughly eliminate the workload of labor cleaning's dust deposit in flue, it is to avoid the alumina raw material dust collector in artificial deashing process.Wherein instantaneous increase air conduction amount can be strengthened ash-removal effect by high-speed compressed air by drain straight tube and drain oviduct.
