Description

The cage material separation device

Technical field

The utility model relates to a kind of cage material separation device, belongs to the material separation device field.

Background technology

By the end of the year 2010, surplus domestic aluminium industrial electrolysis aluminium production capacity reaches 2,000 ten thousand tons.300,000 tons of production capacity electrolytic aluminium factory generally will design electrolytic aluminum smoke dry purifying system 4 covers, and every suit dry fume purifying system mainly designs installations and facilities such as 20 left and right sides pulsed jet cloth filters, 1 carrying alumina fluorine feed bin, fresh feed bin, aluminium oxide warehouse and the ultra concentrated phase chute of aluminium oxide.

Electrolytic aluminum smoke cleaning system most common failure and present industry processing method commonly used has following several kinds:

1, putty often is mixed with hardboard class material in system's flue gas, very easily stop up dust remover hopper, causes not discharge of indivedual hoppers; Very easily cause the ultra concentrated phase chute in each position to stop up owing to contain sandstone and impurity in the aluminium oxide; Ultra concentrated phase chute boiling plate fault also can cause certain chute to stop up; Aluminium oxide makes moist and is prone to cause feed bin bottom to form to harden to cause feed bin putty, not blanking.A large amount of sandstones are often assembled at the position that sedimentation chute is set, clear up untimely also can putty.

2, leak material, it is most common failure that cleaning system is leaked material, all can produce the leakage of partial oxidation aluminium when installations and facilities operation troubles such as deduster, ultra concentrated phase chute, feed bin top and bottom and maintenance.

At present, the method for domestic processing putty mainly is that manual work " is drawn " with hand; " blow " with compressed air; " disclose " with rod.This way causes that aluminium oxide flies upward, labor strength is big.The handling failure time is long, and influence is produced.

Processing spills material, land material and artificial " drawing ", " disclosing " discharging common method is hand sweeping, pack, transports to potroom, and as insulation material, this work causes aluminum oxide secondary, flies upward loss three times, contaminated environment, waste precious resources; Long flow path, labor strength is big; Secondary package is disposable with bag, and expense is high, and waste is serious.Draw out the material and land the material contain a large amount of sandstones, scum, foreign material, not treated being used in causes electrolytic cell iron content, siliceous index exceeding standard in the electrolytic cell, cause the aluminium deterioration in quality;

Also have individual management enterprise not in place, indivedual irresponsible workmans take the way of compressed air " purging ", and " elimination " aluminum oxide dust is local clean, all blows to the other places of being scattered in the air.Both waste a large amount of precious resources, polluted environment again.

Contain the big dirty material of sand impurity content in addition individually and can't use directly and outwell, both caused the wasting of resources, again contaminated environment.

Also have a small amount of enterprise, adopt the method for general industrial dust catcher " suction ", this method also has very big limitation, and the one, the aluminum electrolytic decontamination regional magnetic field is very big, and 20-100 Gauss is generally arranged, and is uneven distribution, and the dust catcher motor is fragile; The 2nd, the suction of general industry dust catcher is limited in one's ability, and it is too late to contain the dirty material ability of sandstone foreign material in the treatment system; The 3rd, the pending dirty material amount of system is big, and general industry dust catcher hopper is limited, the batch turning difficulty, and workload is big, and produces reentrainment of dust.The 4th, the aluminum electrolytic decontamination zone is big, nearly 30 meters of highest point, and rice surplus in the of long 200, rice surplus in the of wide 50, in so big zone, mobile industrial dust catcher and suction tube thereof are very difficult, labour intensity is big.These reasons cause industrial dust collector of non-ideal use in the electrolytic cleaning zone.

Summary of the invention

The purpose of the utility model provides a kind of advantage that can utilize the electrolysis flue gas cleaning system, the cage material separation device that the alumina material that reclaims and impurity foreign material are effectively separated.

The purpose of the utility model is realized by following mode:

The utility model comprises the cage frame and is fixed on the screen cloth on the cage frame, it is characterized in that: the bilateral symmetry of cage frame guide wheel is installed, be provided with storage bin hopper in the bottom of cage frame, the bottom of storage bin hopper is provided with turnover panel.

The utility model has the advantages that: easy and simple to handle, can utilize the advantage of electrolysis flue gas cleaning system, the alumina material that reclaims is effectively separated with the impurity foreign material.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the user mode reference diagram of the utility model.

The specific embodiment

With reference to accompanying drawing 1, the utility model comprises cage frame 1 and is fixed on the screen cloth 2 on the cage frame that screen cloth 2 adopts stainless steel mesh; The bilateral symmetry of cage frame 1 guide wheel 3 is installed; Be provided with storage bin hopper 4 in the bottom of cage frame 1, the bottom of storage bin hopper is provided with turnover panel 5, is provided with hanger 6 at cage frame 1 top; In cage material separation device upper design the fast insert-pull joint is arranged, be used for being connected fast and separating with feed pipe.

In use, with reference to accompanying drawing 2, in flue 11 upper sheds of electrolysis flue gas cleaning system, fixed guide fixed mount and guide rail 12 on the walling of flue of opening are installed hermatic door 9 on opening, hanger rail type electric hoist 7 is installed above flue opening.The guide wheel of the utility model is combined to put into flue 11 from opening with guide rail 12, close hermatic door 9, on hermatic door 9, connect feed pipe 10, the pipe end of feed pipe 10 is connected with the fast insert-pull joint of cage material separation device.Through the alumina material that the negative pressure dust exhaust apparatus reclaims, send in the cage material separation device through feed pipe 10, utilize the flue gas purification system flue negative pressure, carry out the selection by winnowing removal of impurities.The aluminium oxide for reclaiming through separator directly gets into production system, and the foreign material sandstone that stays falls in the storage bin hopper 4, when the foreign material sandstone reaches some; Open hermatic door 9; Fixing lifting rope on the hanger 6 of cage material separation device, lifting rope hangs on the suspension hook 8 of electric hoist 7, with electric hoist 7 the cage material separation device is hung out from flue 11; Guide rail through electric hoist moves to the cage material separation device on the dustbin, opens the turnover panel 5 of storage bin hopper bottom foreign material are discharged.

The cage material separation device of the utility model is not limited to separation of oxygenated aluminium material and impurity foreign material, and it is applicable to that all can carry out the occasion of feed separation through selection by winnowing or wet concentration.
