Description
Technical Field
The invention belongs to the technical field of comprehensive utilization of nonferrous metallurgy and industrial waste residues, relates to the field of comprehensive utilization and recovery of fine iron powder from red mud discharged in the aluminum production industry, and particularly relates to a fine iron powder arc field separation system.
Background
The red mud is industrial solid waste discharged when alumina is extracted in the aluminum production industry, is rich in iron, aluminum, calcium, silicon, titanium, sodium, nickel, manganese, chromium, vanadium, scandium, yttrium and lanthanide rare earth elements, can be changed into valuables by comprehensive development and utilization, achieves zero emission of pollutants, accords with the national trend of circular economy and environmental protection, and particularly under the condition that mineral resources are increasingly lacked, the recovery of valuable metals in the red mud is increasingly important. At present, the red mud is recycled mainly by extracting iron minerals from the red mud, iron oxide rich in the red mud is reduced into ferric oxide through roasting, then the ferric oxide is separated from other contents through magnetic separation, and finally solid is leached out to obtain iron fine powder. However, the refined iron powder obtained in the way has high alkali content and low purity, and the prepared product has poor processing effect and lower price and economic benefit compared with the same-grade iron concentrate.
In the prior art, as shown in fig. 1, a conductor (such as fine iron powder) and a nonconductor (such as an alkali compound) are generally separated by an electro-separation technique, and in common equipment such as a drum-type electro-separator, mineral particles enter an air ionization region with a large amount of free electrons along with a rotating roller, at this time, no matter the conductor or the nonconductor can adsorb negative charges, but due to the difference of electrical properties of the mineral particles, the conductor charges are rapidly transmitted through the rotating roller, and the conductor and the nonconductor move in different tracks due to the difference of the electrical conditions, so that the separation is obtained. This system has the following problems: mineral particles move into the equipment in a free falling manner under the action of gravity, are extremely easy to accumulate on a rotating roller in a large amount, and are possibly subjected to 1, incomplete electrification in an ionization region, non-electrified non-conductors are selected as conductors, and the separation rate is low; 2. the conductive ore particles accumulated above cannot lose charges because of being unable to contact with the surface of the roller, and are regarded as non-conductors to flow out of the tailing tank, so that the yield is low; 3. when the conductors with lost charges do separation movement, because the conductors are still in the range of the air ionization region, the possibility of charging the charges again still exists, if the conductors are charged for the second time, a layer of nonconductor which cannot lose the charges already exists on the roller, the conductors cannot lose the charges for the second time, and the conductors are regarded as nonconductors to flow out of tailings, so that the yield is low.

wherein, the first transmission wheel 252 is arranged at the connection position of the upper surface and the inclined surface, the upper surface and the straight surface, and the lower surface and the straight surface;
wherein the second transfer wheel 253 is arranged at the joint of the lower surface and the inclined surface;
wherein, the tailing brush 254 is arranged on one side of the conveying crawler 251 close to the straight surface and is in contact with the straight surface crawler;
preferably, the second feed opening 21 has a first feed area, and the first feed area is a projection area of the second feed opening in the horizontal direction; and the number of the first and second electrodes,

In this embodiment, the separating apparatus includes a conveyor member including a conveyor track, a first conveyor wheel, a second conveyor wheel, and a tailings brush. Charged ore particles are scattered in the horizontal direction in the offset assembly (namely the tail end of the arc field generating device) to form a lamellar ore particle layer, then enter the separating device through the second feeding hole and fall on the conveying crawler belt, the ore particles with good conductivity lose electric charges immediately and are non-electric due to the grounding of the conveying crawler belt, the ore particles fall into the conductor material discharging hole through oblique throwing movement from the tail end of the inclined surface of the conveying crawler belt, and the non-conductor ore particles cannot lose the electric charges, are adsorbed on the conveying crawler belt and move along with the conveying crawler belt until the ore particles are brushed by tailing brushes and fall into the non-conductor material discharging hole.
Example 4: the second transfer wheel 253 has a diameter 2 times the diameter 252 of the first transfer wheel.
In this embodiment, the diameter of the second conveying wheel is larger than that of the first conveying wheel, when the ore particle layer on the conveying crawler moves to the joint of the inclined plane and the lower surface, the second conveying wheel has a larger diameter, so that the conductor ore particles losing charges can fly out in the direction away from the conveying crawler under the action of centrifugal force, and the centrifugal force is larger when the diameter is larger, so that the diameter of the second conveying wheel is larger, and the separation effect is better; meanwhile, because the conductivity of the semiconductor is between the conductor and the non-conductor, the adsorption capacity of the semiconductor by the crawler is lower than that of the non-conductor, and if the second conveying wheel with an overlarge diameter is arranged, the semiconductor which is not firmly adsorbed is easily separated from the conveying crawler due to overlarge centrifugal force and falls into a conductor material discharge port, so that the separation purity is influenced; therefore, the diameter of the second transmission wheel is set to be twice of that of the first transmission wheel by comprehensively considering two influencing factors.
Example 5: the separator assembly 24 further comprises:
the eccentric wheel group 26 is formed by a plurality of eccentric wheels which are distributed at intervals a;
wherein the eccentric wheel set 26 is disposed under the inclined plane of the conveying track 251.
The ore particles enter the separating device after the arc field generating device is electrified, even if the ore particles are dispersed in the horizontal direction when entering the separating device, the possibility of small accumulation still exists when the ore particles fall on the upper surface of the conveying crawler belt, the charged conductor ore particles accumulated above the ore particles cannot lose electric charges due to the fact that the charged conductor ore particles cannot be in contact with the grounding crawler belt, and therefore the charged conductor ore particles are adsorbed on the crawler belt and are brushed by tailings to fall into a non-conductor material discharge chute, and the recovery of conductor materials is influenced.
In this embodiment, the conductor mineral aggregate that has lost electric charge receives the effect of gravity to landing downwards on the inclined plane of conveying track, leaves blank area on the inclined plane, through set up eccentric wheel group below the inclined plane, makes the track inclined plane can produce the law shake in service to make accumulational mineral aggregate tremble and scatter, electrified conductor mineral aggregate loses electric charge and landing immediately when contacting the inclined plane, falls into conductor mineral aggregate discharge gate, has promoted the rate of recovery of conductor material greatly.
