Abstract
An apparatus for improving the quality of vanadium slag includes a vanadium slag furnace, a conveyor belt is arranged below the material outlet of the vanadium slag furnace, the other end of the conveyor belt is positioned at the material inlet of a screening box, a crushing oar is arranged in the screening box, a magnetic separator is arranged below the crushing oar, the taphole of the magnetic separator is positioned at the central portion of the screening box, a screen mesh disc is arranged below the magnetic separator, the edge of the screen mesh disc is positioned in the slide way of the inner wall of the screening box, the bottom of the screen mesh disc is connected with a follower cooperating with a cam, the cam is connected with the output shaft of a motor, the lower portion of the sidewall of the screening box is provided with a slag outlet, the sidewall of the screening box is provided with a coarse slag outlet, the coarse slag outlet is connected with a conveyer belt, and the other end of the conveyer belt is connected with a vanadium slag furnace. The apparatus has reasonable structure design and ingenious and novel conception; and coarse vanadium slag is extracted by the screening box to reduce the content of metallic iron in the coarse vanadium slag in order to reduce the cost of the coarse vanadium slag-to-fine vanadium slag process, so the vanadium extraction efficiency is increased, and the quality of products is stable, thereby the transformation of steel enterprise production and resource and equipment management is promoted.
Description
Technical field
The invention belongs to smelting iron and steel technical field, particularly relate to a kind of equipment improving vanadium slag quality.
Background technology
In China, South Africa, Russia, China, New Zealand, Finland etc., part iron factory adopts v-bearing titanomagnetite smelting.In order to ensure effective extraction and application of vanadium and iron resources, needed to carry out vanadium extraction before steel-making.The main raw material of vanadium extraction is thick vanadium slag, the extraction process ubiquity vanadium extraction auto-control level of thick vanadium slag is low, continue to use artificial experience fuzzy control accurate not, random large, cause labour intensity large, vanadium extraction efficiency is low, thick vanadium slag quality and half steel quality instability, serious safety and sanitation and the problem of environmental pollution.
Summary of the invention
The invention provides a kind of equipment improving vanadium slag quality, with solve propose in above-mentioned background technology problem.
Technical problem solved by the invention realizes by the following technical solutions: the invention provides a kind of equipment improving vanadium slag quality, comprise vanadium slag stove, travelling belt is provided with below the discharge port of vanadium slag stove, the other end of travelling belt is positioned at the opening for feed place of screen box, pulverizing oar is provided with in screen box, pulverize below oar and be provided with magnetic separator, the iron notch of magnetic separator is positioned at the middle part of screen box, the below of magnetic separator is provided with screen disc, the edge of screen disc is positioned at the slideway of screen box inwall, screen disc bottom connects the driven member with cam engagement, cam connects the output shaft of motor, the bottom of screen box sidewall is provided with slag notch, screen box sidewall is provided with the outlet of thick slag, thick slag exit is connected with conveying belt, the conveying belt the other end connects vanadium slag stove.
Described thick slag outlet is positioned at the upper limb of slideway.
Described screen disc is incline structure.
Described magnetic separator is provided with scraper plate.
Driven member that is described and cam engagement and screen disc weld together.
Beneficial effect of the present invention is: in the workshop of smelting iron and steel, reasonable in design, be skillfully constructed novelty, thick vanadium slag is through the extraction of screen box, reduce metal Ferrum content in thick vanadium slag, reduce the cost of thick vanadium slag to smart vanadium slag operation, vanadium extraction efficiency is improved, and is that quality product is more stable.And then promote iron and steel enterprise's production, resource and equipment control change.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further: the invention provides a kind of equipment improving vanadium slag quality, travelling belt 3 is provided with below the discharge port 2 of vanadium slag stove 1, the other end of travelling belt 3 is positioned at the opening for feed place of screen box 6, be provided with in screen box 6 and pulverize oar 4, pulverize below oar 4 and be provided with magnetic separator 5, the iron notch 7 of magnetic separator 5 is positioned at the middle part of screen box 6, the below of magnetic separator 5 is provided with screen disc 12, the edge of screen disc 12 is positioned at the slideway 8 of screen box 6 inwall, screen disc 12 bottom connects the driven member coordinated with cam 11, cam 11 connects the output shaft of motor 10, the bottom of screen box 6 sidewall is provided with slag notch 9, screen box 6 sidewall is provided with the outlet of thick slag, thick slag exit is connected with conveying belt 13, conveying belt 13 the other end connects vanadium slag stove 1.Described thick slag outlet is positioned at the upper limb of slideway 8.Described screen disc 12 is incline structure.Described magnetic separator is provided with scraper plate.The described driven member coordinated with cam 11 and screen disc 12 weld together.
In thick vanadium slag leaching process, thick vanadium slag in vanadium slag stove 1 is sent in screen box 6 by travelling belt 3, and it is by pulverizing oar 4, it is broken, become in the process fallen and carry out the operation of suction magnet by magnetic separator, by scraper plate the iron on magnetic separator scraped again and cut, by iron notch 7 exclude filter case 6, the vanadium slag of magnetic separation drops on screen disc 12, because screen disc 12 is driven by cam 11, thus vanadium slag is moved up and down on screen disc 12, the vanadium slag that volume is larger is got rid of from slag notch 9, send vanadium slag stove 1 back to by conveying belt 13 and carry out next round screening, 9 are got rid of from slag notch by the vanadium slag of screen disc 12.
The present invention is used in the workshop of smelting iron and steel, reasonable in design, be skillfully constructed novelty, thick vanadium slag is through the extraction of screen box 6, in broken crushing process, magnetic is carried out to the metallic iron pounded out, reduce metal Ferrum content in thick vanadium slag, reduce the cost of thick vanadium slag to smart vanadium slag operation, vanadium extraction efficiency is improved, and is that quality product is more stable.And then promote iron and steel enterprise's production, resource and equipment control change.
