Abstract
This invention discloses method and equipment for preventing blanking blockage of alumina feed box. During the blanking of the cylindrical blanking machine in the alumina feed box, compressed air is introduced into the alumina feed box to blow against the outlet of the cylindrical blanking machine. Alumina at the outlet is thus boiling, which can prevent the blockage of the blanking machine. This invention introduces compressed air into the alumina feed box, i.e., adds a backblowing pipe close to the blanking machine that can blow during blanking so that alumina at the outlet is boiling, thus can prevent the blockage of the blanking machine and guarantee the operation of the electrolytic cell.
Description
Technical field:
The present invention relates to a kind of method and device that prevents that the alumina reservoir blanking from stopping up, belong to the alumina reservoir technical field that is used to add alumina raw material in the Aluminium Electrolysis.
Background technology:
At present, the employed alumina reservoir of Aluminium Electrolysis generally only is equipped with the cartridge type blanking device in the prior art, the shortcoming of this alumina reservoir is: when the quality of alumina material is not fine or alumina material when making moist, its alumina material can be combined into the block feed opening that stops up blanking device, thereby cause blanking device blanking amount to reduce, even can't blanking, this has not only reduced production efficiency, but also can have a strong impact on the ordinary production of electrolyzer.
Summary of the invention:
The objective of the invention is: provide a kind of implement easy, that reliability the is high method and the device that prevent alumina reservoir blanking obstruction, to overcome the deficiencies in the prior art.
The present invention is achieved in that the method that prevents that the alumina reservoir blanking from stopping up of the present invention is: during its cartridge type blanking device blanking in alumina reservoir, in alumina reservoir, feed pressurized air, and pressurized air blown facing to the feed opening of cartridge type blanking device, make the alumina material at feed opening place produce boiling, can prevent that like this feed opening place from gathering materials and stop up feed opening.
The device that prevents that the alumina reservoir blanking from stopping up of the present invention is: it comprises the alumina reservoir (1) that cartridge type blanking device (3) are installed, the anti-blowpipe (2) that can be connected with compressed air source is installed on alumina reservoir (1), and be provided with nozzle (4) on the port of anti-blowpipe (2) in inserting alumina reservoir (1), the tuyere of nozzle (4) is facing to the feed opening of cartridge type blanking device (3); In inserting alumina reservoir (1), be provided with 1～5 nozzle (4) on the port of anti-blowpipe (2); The blanking cylinder of its anti-blowpipe (2) and cartridge type blanking device (3) is connected with same compressed air source, and the blanking cylinder of anti-blowpipe (2) and cartridge type blanking device (3) is communicated with or cuts off with compressed air source simultaneously.
Owing to adopted technique scheme, the present invention has introduced pressurized air in original alumina reservoir, promptly on alumina reservoir, increased anti-blowpipe near cartridge type blanking device place, when the blanking of cartridge type blanking device, its anti-blowpipe nozzle blows facing to feed opening at this moment, make the alumina material at feed opening place seethe with excitement, the situation of stopping up feed opening like this with regard to having avoided the feed opening place to gather materials takes place, the working stability performance of alumina reservoir blanking is improved greatly, thereby guaranteed the ordinary production of electrolyzer.Therefore, the present invention compared with prior art, the present invention not only has can prevent hopper feed opening putty and the high advantage of working reliability, but also have construction easy, easy for operation, can guarantee the advantage of hopper useful volume again.
Description of drawings:
Accompanying drawing 1 is the structural representation of apparatus of the present invention;
Accompanying drawing 2 is that the A of accompanying drawing 1 is to synoptic diagram.
Embodiment:
Embodiments of the invention: adopt in alumina reservoir, feed pressurized air and with pressurized air facing to the method that the feed opening of cartridge type blanking device blows, make the alumina material at feed opening place produce boiling, can prevent that like this feed opening place from gathering materials and stop up feed opening.During concrete enforcement, can on the basis of the existing alumina reservoir (1) that cartridge type blanking device (3) are installed, transform, soon the steel plate of an anti-blowpipe (2) on alumina reservoir (1) penetrates in the alumina reservoir (1) and welds thereon, the nozzle (4) that is installed on anti-blowpipe (2) port is located near the feed opening (5) of cartridge type blanking device (3), in order to guarantee boiling effect to alumina material, preferably the nozzle (4) to anti-blowpipe (2) carries out bifurcated, make its nozzle (4) become two, simultaneously, in order to make nozzle (4) be unlikely to returning charge, and can make pressurized air more concentrated again, preferably two nozzles (4) end all is made into flat; Then another termination of anti-blowpipe (2) and the blanking cylinder of cartridge type blanking device (3) are connected with same compressed air source, the blanking cylinder of anti-blowpipe (2) and cartridge type blanking device (3) can be connected with compressed air source simultaneously or cut off, can guarantee that like this blanking of the compressed-air actuated air inlet of anti-blowpipe (2) and blanking device (3) is synchronous.
During device work of the present invention, when pressurized air is controlled the blanking device blanking by the cylinder on the cartridge type blanking device (3), its blanking device mouth is opened, anti-blowpipe this moment (2) also is passed into pressurized air, and under the compressed-air actuated effect of anti-blowpipe (2), the alumina material at feed opening place is seethed with excitement, so not only prevented the blocked of alumina reservoir feed opening, and make its blanking become unobstructed, thereby guaranteed the blanking amount, the production of finally having stablized electrolyzer.
Claims (4)
1. method that prevents that the alumina reservoir blanking from stopping up, it is characterized in that: during its cartridge type blanking device blanking in alumina reservoir, in alumina reservoir, feed pressurized air, and pressurized air blown facing to the feed opening of cartridge type blanking device, make the alumina material at feed opening place produce boiling, can prevent that like this feed opening place from gathering materials and stop up feed opening.
