Abstract
The invention provides a mixing device of fluorinated alumina powder, which comprises two feeding chute pipes and a material mixing box, wherein two sides of the bottom of the material mixing box are communicated with electrolytic tanks of a first workshop and a second workshop by feeding pipelines equipped with feeders respectively; the ends, on the same side, of the two feeding chute pipes are communicated with a premixing chute pipe; the middle part of the premixing chute pipe is downwards communicated with a horizontally arranged premixed material conveying chute pipe; and an outlet at the other end of the premixed material conveying chute pipe is communicated with a middle material discharging pipe which is vertically arranged in the middle of the upper surface of the material mixing box and is communicated with the interior of the material mixing box. According to the invention, the unsmooth feeding and unsmooth discharging caused by tiny alumina particles are improved greatly; burst effects of the electrolytic tanks caused by the unsmooth discharging are improved obviously; mixed alumina used by the various electrolytic tanks are mixed uniformly.
Description
Technical field
The invention belongs to electrolytic aluminum apparatus field, particularly relate to a kind of mixing device of fluorinated alumina powder.
Background technology
As shown in Figure 1, 2, in electrolytic aluminum feeding process, when air lift blower fan and the collecting machine work of top, storehouse, due to the effect of gravity and negative pressure, the aluminum oxide causing particle large falls in warehouse side accumulation, the aluminum oxide of finely powdered falls in collecting machine bottom and is deposited in the opposite side of warehouse, needs to be mixed to send into electrolyzer.Two feed openings are provided with and elephant trunk 1` is communicated with mixer 4` bottom warehouse, because mixer volume is too large, the fluorinated alumina that two ends enter mixer cannot mix and entered feed lines and be sent to potroom, occur that large-grain alumina enters the first workshop electrolyzer, finely powdered aluminum oxide enters the second workshop electrolyzer, the material thickness of each electrolyzer is not mixed, and due to finely powdered aluminum oxide poor fluidity, often regularly occur the slow or groove top of feeding have material not under phenomenon, electrolyzer is caused to occur burst effect waste power consumption and other groove condition corruptions.
Summary of the invention
Object of the present invention is exactly the mixing device just deficiency existing for above-mentioned prior art being provided to a kind of fluorinated alumina powder.
The present invention realizes the technical scheme that above-mentioned purpose adopts: a kind of mixing device of fluorinated alumina powder, it comprise two horizontally disposed tops respectively with macrobead fluorinated alumina opening for feed, the feed chute that small-particle fluorinated alumina opening for feed is connected, and it is large for mixing, the mixer of small-particle fluorinated alumina material, respectively by the feed lines and first being provided with feed appliance bottom described mixer both sides, the electrolyzer in the second workshop is connected, the same side of described two feed chutes is communicated with a pre-mixing elephant trunk, horizontally disposed Preblend conveying chute is communicated with downwards in the middle part of described pre-mixing elephant trunk, the other end outlet of described Preblend conveying chute be vertically set on Middle face on mixer, and the intermediate blanking pipe communicated with mixer inside is connected.
The both sides port of described pre-mixing elephant trunk is all communicated with the auxiliary feeding pipe being provided with flow control valve and blower fan.
The top of described mixer is also symmetrically arranged with the balance stock column that two are played scavenging action.
Principle of the present invention is: because mixer volume is too large, and the fluorinated alumina that two ends enter mixer cannot mix and entered feed lines and be sent to potroom.Therefore, standpipe two ends being entered mixer changes the middle part that a standpipe enters mixer into, at the former standpipe feed chute the other end by arranging pre-mixing elephant trunk former thing two ends feed chute UNICOM, mixer is entered by Preblend conveying chute and intermediate blanking pipe, and on pre-mixing elephant trunk, increase by-pass valve control carry out blast and assist convey materials, accomplish that aluminum oxide fully mixes with mixer in each elephant trunk, then evenly deliver in electrolyzer, also accomplish the even blanking in mixer internal oxidition aluminium both sides simultaneously, stop to occur large dead material region; Whether smooth and easyly there is uncertainty because aluminum oxide flows out in mixer, therefore need increase the conveying that gas barrier be convenient to aluminum oxide on mixer top.
The beneficial effect that the present invention takes technique scheme to bring is: the present invention is owing to adding pre-mixing elephant trunk, and select from blanking in the middle part of mixer, adding auxiliary handling equipment, the beneficial effect brought is: the not smooth phenomenon of the feeding 1, caused because alumina particle is tiny, blanking obtains very large change; 2. the burst effect that electrolyzer does not freely cause because of blanking is obviously improved; 3. the mixed aluminium oxides thickness that each electrolyzer uses mixes unanimously.
