Description

Technical Field

[0001] The invention relates to the technical field of recovery devices, and in particular to a lead-zinc ore residue recovery device. Background Art

[0002] Lead-zinc ore residue is solid waste residue produced in the process of smelting lead-zinc ore. This solid smelting slag usually contains iron and lead, which are the iron-lead symbiotic particles in these solid waste residues. Zinc slag can be divided into dry slag and water slag. The current process is mainly based on wet slag. The iron-lead symbiotic particles in the wet slag and zinc slag are wrapped in the solid waste residue. In order to separate the iron-lead symbiotic particles, the zinc slag must be crushed and ground. After the lead-zinc ore residue is crushed and ground, due to the symbiosis of iron and lead in the zinc slag, the iron-lead symbiotic particles can be recovered by using a magnetic separator using the high magnetic permeability of iron. The magnetic separator used to recover the iron-lead symbiotic particles in the lead-zinc ore residue can be called a lead-zinc ore residue recovery device;

[0003] However, the existing magnetic separation type lead-zinc ore residue recovery device has the problem that only the outer peripheral surface of the drum is used to absorb the magnetic material in the ore pulp. During the working process, since the magnetic attraction decreases with the increase of distance, the drum can only absorb the magnetic material in the ore pulp near the surrounding distance, and the material utilization rate is low. If the magnetism is increased, the magnetic material containing more impurities in the ore pulp near the outer peripheral surface of the drum will be adsorbed, affecting the purity of the obtained magnetic material. Patent No. CN116764805A in the prior art is a wet magnetic separator. By adopting a magnetic separation drum with a spirally wound magnetic separation flow channel, the ore pulp can enter the magnetic separation flow channel as the magnetic separation drum rotates and spirally flow in the magnetic separation flow channel, and finally flow into the inner cavity of the magnetic separation drum. The spirally wound magnetic separation flow channel design fully utilizes the internal space of the magnetic separation drum, extends the magnetic separation path, and enables the magnetic material in the ore pulp entering the magnetic separation drum to be effectively magnetically separated and reliably adsorbed on the inner wall surface of the magnetic separation flow channel, which greatly improves the magnetic separation accuracy, thereby solving the above-mentioned problem.

[0004] However, when this magnetic separation type lead-zinc ore residue recovery device is used to adsorb iron-lead co-existing particles in the flowing lead-zinc ore slurry, the outer surface of the magnetic suction cup will be contaminated with the slurry. When the equipment is stopped, in order to prevent the solidification of the slurry from affecting the magnetic force of the magnetic suction cup, it is necessary to clean it manually. After the cleaning is completed, since the magnetic suction cup is in contact with water for a long time, in order to prevent it from rusting, an anti-rust liquid can also be applied to its outer surface. The maintenance process of this equipment is relatively cumbersome. In addition, since the ore residue is calcined in a rotary kiln during the refining of lead-zinc ore and contains a high calorific value (generally above 2000 kcal), the waste residue also has a high value. It can be sold to a brick factory after the water source and impurities in the slurry are removed by a slurry vibration slag removal device and used as a raw material for internal combustion bricks. This process requires the purchase of a corresponding slurry vibration slag removal device, which is costly. Therefore, it does not meet the existing needs. In this regard, we propose a lead-zinc ore residue recovery device. Summary of the invention

[0005] The object of the present invention is to provide a lead-zinc ore residue recovery device to solve the problem proposed in the above background technology that when using this magnetic separation lead-zinc ore residue recovery device to adsorb iron-lead co-existing particles in the flowing lead-zinc ore slurry, the outer surface of the magnetic suction cup will be contaminated with the slurry. When the equipment is stopped, in order to prevent the solidification of the slurry from affecting the magnetic force of the magnetic suction cup, it is necessary to manually clean it. After the cleaning is completed, since the magnetic suction cup is in contact with the water source for a long time, in order to prevent it from rusting, an anti-rust liquid can also be applied to its outer surface. The maintenance process of this equipment is relatively cumbersome. In addition, since the ore residue is calcined in a rotary kiln during the refining of lead-zinc ore, it contains a high calorific value (generally above 2000 kcal), so the waste slag also has a high value. It can be sold to a brick factory after removing the water source and impurities in the slurry through a slurry vibration slag removal device and used as a raw material for internal combustion bricks. This process requires the special purchase of a corresponding slurry vibration slag removal device, which has a high cost.
