Description
Technical field
The utility model relates to a kind of aluminium cell gas control cabinet, is fit to be applied in the aluminium electrolysis prebaked anode production system, especially is fit to be applied in the super large grooved aluminium electrolysis prebaked anode production system.
Background technology
Along with the startup of domestic super-huge 600 kA large-scale pre-baked cells, representing the development that China's aluminium electrolysis prebaked anode production system has entered environment-friendly type, striden the epoch.Pneumatic control cabinet can adapt to strong current, upfield environment, satisfy the demand for development of environmental protection, safety, stable, efficient modern aluminum electrolysis process, in time the aluminium electrolysis shop production unit is carried out conduct monitoring at all levels and feedback, reduce on-the-spot artificial operational ton in the production process, to realize full-automatic modern management.
Behind the slot control machine receive data, send the action control signal, control signal has several commutation electrically-controlled valve by the gas control cabinet of cable to the electrolysis trough rim in the gas control cabinet, the commutation electrically-controlled valve again by pneumatic pipeline control crust breaking, go out aluminium cylinder, the action of constant-volume blanking device.Pressurized air enters in crust breaking cylinder, the constant-volume blanking device cylinder after the commutation electrically-controlled valve in the gas control cabinet by main supply air pipe and a supply air line again, finishes crust breaking, reinforced action.
Present domestic Pneumatic control cabinet has two kinds of forms: the commutation electrically-controlled valve connects by copper pipe in the one gas control cabinet, the copper pipe wall thickness makes the actual air circulation area not enough, caused and dammed, in actual production process, can make constant-volume blanking device and crust breaking, go out aluminium cylinder work hysteresis.The tube road is connected and is not easy to maintaining, takes up room greatlyr between electric control reversing valve and the valve, and the electric control reversing valve replacement time after the life cycle is longer, thereby impact is produced.
Electric control reversing valve spool gap is too small in its two gas controls cabinet causes electric control reversing valve work smooth and easy not.Wire barrel is passed by in complexity, easily entanglement.
All in cabinet, the electric control reversing valve exhaust all can not in time be discharged in the gas control cabinet in exhaust in the current electrolysis groove Pneumatic control cabinet, and the exhaust in cabinet of the mist of oil in the three linked piece causes the cabinet internal contamination, affects the electric elements life-span in the cabinet.And all provide system without temperature.
Electric current in the 600KA large-scale pre-baked cell, magnetic field are huge.Pressurized air by main supply air pipe and supply air line output after electric control reversing valve control enter crust breaking, go out aluminium cylinder, in the constant-volume blanking device, because of inlet, outlet pipeline internal diameter less, easily form and dam, make gas supply flow not enough, cause upper part of the electrolytic cell far-end constant-volume blanking device, crust breaking cylinder operation power not enough, action lags behind, and makes that constant-volume blanking device leaks material, crust breaking cylinder is slow in one's movements or attonity, overall work lags behind, and can not finish smoothly on request crust breaking, reinforced action.
Summary of the invention
It is valve island control form that a kind of aluminium cell gas control cabinet, this gas control cabinet inside are taked large flow set dress control form, has and controls out aluminium, crust breaking cylinder and constant-volume blanking device holding function.This gas control cabinet is exported source of the gas and is guaranteed flow from the air inlet to the electric control reversing valve, guarantee supply gas pressure, reduces the space pipeline loss, guarantees commutation electrically-controlled valve good working order, increases the service life.The problem that signalizing activity lags behind can not appear in the gas control cabinet, finishes smoothly crust breaking, the action such as reinforced.The electric control reversing valve exhaust can be taked to concentrate on the outer exhaust of cabinet or draw the outside exhaust of potroom in the cabinet, avoids greatly because of electric elements in the various greasy dirt remote effect cabinets that exhaust brings in cabinet of the mist of oil in the three linked piece, and is environment friendly and pollution-free.
This aluminium cell gas control cabinet adopts valve island structure, is respectively equipped with gas source air inlet port, gas source production well, commutation electrically-controlled valve on the valve island and often leaves pore, the commutation normally closed production well of electrically-controlled valve and public venting hole.
Gas source passes to the valve island through the source of the gas three linked piece with source of the gas, by the valve island gas source is distributed to each electric control reversing valve, and when gas source was reset mode by electric control reversing valve, electric control reversing valve was often left pore and tracheae, cylinder intake; When gas source is working order by the commutation electric control reversing valve, the normally closed production well of electric control reversing valve and tracheae, cylinder is given vent to anger.And electric control reversing valve reset and work in a flash, unnecessary waste gas is discharged by the common exhaust pipe road.Be provided with the independent back flushing wind apparatus in the system, can carry out independent control fully when needed.
In gas control cabinet housing, thermal insulation layer and heating tape are set, effectively keep the temperature in the gas control cabinet, the normal operation of gas control cabinet under cold environment.
Concrete technical scheme of the present utility model is as follows: a kind of aluminium cell gas control cabinet, outside at gas control cabinet housing is provided with the source of the gas three linked piece, the end of source of the gas three linked piece links to each other with valve island in the gas control cabinet housing by pipeline, also be connected with the pipeline that reaches gas control cabinet hull outside on the end face on valve island, pipeline communicates from the different gas circuits of inside, valve island; Be provided with two-position three way magnetic valve and two-position four-way solenoid valve on the valve island, two-position three way magnetic valve and two-position four-way solenoid valve be the break-make of pilot piping respectively; Other end on the valve island connects respectively back-blowing inlet pipe and common exhaust pipe, and back-blowing inlet pipe and common exhaust pipe are stretched out respectively gas control cabinet housing.
The internal layer of described gas control cabinet housing is provided with thermal insulation layer; Be provided with heating tape in the gas control cabinet housing, heating tape is connected with air switch by supply lead, and air switch is arranged on the inwall of gas control cabinet housing.
Be provided with connection terminal in the described gas control cabinet housing, connection terminal is connected with two-position four-way solenoid valve with two-position three way magnetic valve respectively by electric wire.
The commutation electrically-controlled valve is provided with band memory hand gear, manual work when assurance solenoid or Controlling System break down in the described gas control cabinet; Use when being convenient to equipment debugging and needing crawl work.This kind commutation electrically-controlled valve is that valve island packaging type connects, need not to change disposable permanent being benefited of valve plate.
The deficiency that the utility model exists in order to solve gas control cabinet prior art, many connecting pipelines in the gas control cabinet have in the past been cancelled, connecting tube between valve and the valve omits fully, the greatly minimizing accident factor and the dimension inspection personnel's of enterprise repair density and the maintenance cost after the operation.Make system more succinct, electric control reversing valve is installed compact, and is rationally distributed, move smooth and easyly, is easy to change, replaceable good in about 2 minutes if the cabinet internal valve breaks down, and do not have the dismounting pipeline, and more convenient operation reduces investment, minimizing maintenance maintenance workload.
