Abstract
The present invention discloses a bottom discharging structure applied to alumina storage bunkers of electrolysis aluminum factories, particularly a bottom discharging structure of alumina storage bunkers and the discharging method, which belongs to the technical field of the storage and the transportation of alumina in the process of the electrolytic production of aluminum. The bottom discharging structure of alumina storage bunkers comprises discharge openings, a conveying chute and an air pipe, wherein the conveying chute is composed of at least two conveying chute monomers which can independently discharge stocks; a plurality of discharge openings are arranged above each conveying chute monomers; a discharge region is composed of each conveying chute monomer and the discharge openings arranged on the conveying chute; the conveying chute monomer arranged on each discharge region is connected with the air pipe through an air conveying duct; a control valve used for control air supply is arranged on the air conveying duct. The alumina arranged in the alumina storage bunkers of the present invention uniformly flows, the discharge openings arranged on the bottom of the storage bunkers are in an orderly controllable discharge state, obsolescence of the alumina arranged in the storage bunkers is obviously reduced, the utilization rate of the storage bunkers is improved, the stress of the side walls of the storage bunkers is uniform, and the service life of the storage bunkers is enhanced.
Description
Technical field
The present invention relates to the aluminium oxide storing field in the Aluminium Electrolysis process, be applied to the bottom discharging of electrolytic aluminium factory aluminum oxide storage bunker, especially relate to a kind of aluminum oxide storage bunker bottom discharging structure and discharging method.
Background technology
Along with the development and progress of world's aluminum electrolysis technology, it is ripe that aluminum electrolysis process constantly tends to.For the aluminium oxide storage system technology of cell feed material also constantly is tending towards perfect, but partly there is certain technological deficiency in storage bunker bottom discharging in the aluminium oxide storage system.
The present situation of aluminum oxide storage bunker bottom discharging part is as follows in the current aluminium oxide storage system: shown in Fig. 1-4, the aluminum oxide storage bunker bottom discharging mode began to use so far from the eighties of last century initial stage nineties at present.Aluminum oxide storage bunker bottom is offered some discharge gates 1, and discharge gate 1 directly is connected with transporting chute 2.Aluminium oxide in the bunker enters transporting chute through discharge gate, enters aluminium oxide master delivery system then.But in actual production process, have only minority discharge gate discharge smooth and easy, and other discharge gate because appearring in regional area, swollen material or compacting phenomenon cause aluminium oxide evenly to discharge in bunker.
There are the following problems to adopt this aluminum oxide storage bunker discharging structure and method:
1. aluminium oxide flows inhomogeneously in the unordered natural discharge of storage bunker bottom discharging mouth, bunker, causes the aluminium oxide storehouse in " dead material " many, takies factory's circulating funds, reduction bunker degree of utilization.
2. because long-term local discharge, cause the distortion of bunker sidewall unbalance stress, shortened bunker service life.
Summary of the invention
The present invention is exactly that provide in order to solve the problems of the technologies described above a kind of can make aluminium oxide in the bunker evenly flow, the storage bunker bottom discharging mouth is in orderly controlled discharge state, improve the bunker degree of utilization, the bunker sidewall is stressed evenly, the aluminum oxide storage bunker bottom discharging structure and the discharging method of bunker long service life.
For solving the problems of the technologies described above, the present invention is achieved in that aluminum oxide storage bunker bottom discharging structure, it comprises discharge gate, transporting chute, air feed pipe, wherein transporting chute by at least two can independent discharge the transporting chute monomer form, the top of each transporting chute monomer is provided with a plurality of discharge gates, a plurality of discharge gates that each transporting chute monomer and its top are provided with are formed a material discharge region, the transporting chute monomer of each material discharge region is connected with airduct by air delivering pipeline, and air delivering pipeline is provided with the control cock that is used to control air feed.
Described each discharge gate place is provided with and is used to control the discharge quantity of discharge gate and the flow-controlling gate of flow.
Described control cock is valves such as electromagnetic valve, pneumatic valve.
A kind of aluminum oxide storage bunker bottom discharging method, it comprises following processing step: a plurality of discharge gates and a transporting chute monomer of aluminum oxide storage bunker are formed a material discharge region, aluminum oxide storage bunker bottom discharging is divided into a plurality of material discharge regions, and the air feed of transporting chute monomer of controlling each material discharge region by control cock is to realize the subregion discharge of bunker.
Described each discharge gate place adds and is used to control the discharge quantity of discharge gate and the flow-controlling gate of flow.
Advantage of the present invention and effect are as follows:
1. because aluminum oxide storage bunker can be realized the subregion discharge, make that the aluminium oxide in the bunker can evenly flow; The storage bunker bottom discharging mouth is in orderly controlled discharge state, and aluminium oxide in the bunker " dead material " can obviously reduce, and improves the bunker degree of utilization.
2. the bunker sidewall is stressed evenly, improves bunker service life.
Below in conjunction with the drawings and specific embodiments the present invention is described in further details.
