Description
Technical field
The present invention relates to a kind of ore-dressing technique.
Background technology
Existingly the mineral powder slurry of flowing through is removed the method for ferromagnetic material or make from top to bottom the mineral powder slurry through soft magnetic medium by magnetized soft magnetic bodies, or be to make from lower to upper the mineral powder slurry through soft magnetic medium.Adopt when making from top to bottom the mineral powder slurry through the soft magnetic medium method, mineral powder is subjected to the effect of self gravitation, pass through easily soft magnetic medium, but, gravitate, the impulsive force that the mineral powder slurry flows downward is large, in the process that flows downward fast, form gas, liquid, solid three solutropes, and produce easily swabbing, the ferromagnetic material that not only affects easily in the mineral powder slurry is drawn by soft magnetic medium, and the ferromagnetic material that will be adsorbed on the ferromagnetic medium is easily taken away, thereby impact is except the effect of ferromagnetic material; Adopt when making from lower to upper the mineral powder slurry through the soft magnetic medium method, although formed the liquid-solid two-phase solution that is conducive to magnetic separation and the impact of avoiding mineral powder slurry self gravitation, but, because the mineral powder slurry is not solution, mineral powder in the mineral powder slurry precipitates easily, has hindered the proper flow of mineral powder slurry and has removed ferromagnetic material, simultaneously, during cleaning, also can produce a certain amount of remaining slurry needs that contain more ferromagnetic material and further process.
Summary of the invention
Goal of the invention of the present invention is to provide neither can produce ferromagnetic material in a kind of flow process impacts and the suction induced effect, liquid-solid two-phase fluid is only arranged during magnetic separation, can not produce the remaining slurry that contains more ferromagnetic material when cleaning, simultaneously, can not precipitated the fluid deferrization method that affects again.
The present invention realizes like this, comprise mineral powder sizing material iron removing magnetic substance process, the soft magnetic medium cleaning process, mineral powder sizing material iron removing magnetic substance process is in the bottom exports the vertical non-magnetic passage that is provided with valve soft magnetic medium to be set, at the arranged outside south poles of non-magnetic passage relative permanent magnet or calutron, valve-off, the mineral powder slurry is imported in the non-magnetic passage from the top import of non-magnetic passage, until the mineral powder slurry covers soft magnetic medium and soft magnetic medium is immersed in the mineral powder slurry, open valve, make the mineral powder slurry consistent with the amount of valve discharge from the amount that the import of non-magnetic passage top imports, simultaneously, keep the flow velocity of mineral powder slurry in non-magnetic passage to be lower than 3.5cm/ second; The soft magnetic medium cleaning process is to stop to import the mineral powder slurry from the import of non-magnetic passage top, after remaining slurry in passage has been drained from valve, non-magnetic passage is broken away from the relative permanent magnet of south poles or the magneticaction of calutron together with soft magnetic medium, full gate is opened valve, and wash from top to bottom soft magnetic medium by flushing liquor, perhaps by centrifugal method rotation soft magnetic medium, ferromagnetic material on the soft magnetic medium is cleaned out and be excreted on the garbage collection container by valve, clean clean soft magnetic medium and just can again come into operation.The present invention is because that adopt low flow velocity and soft magnetic medium is immersed in the mineral powder slurry draws ferromagnetic material, fluid can keep liquid-solid two-phase, therefore, can not produce impact and suction induced effect to ferromagnetic material in iron removal and exhaust slurry process, and, import from top to bottom the mineral powder slurry, not affected by precipitation.
Here, non-magnetic passage top is provided with lid, cover the import of mineral powder slurry and water Flushing nozzle are set, cover on non-magnetic passage top at mineral powder sizing material iron removing magnetic substance process middle cover, exhaust slurry process in the soft magnetic medium cleaning process, lid is then opened, and makes remaining slurry not be subjected to the effect of vacuum draw and drains smoothly.Adopt lid, make to have certain sealing in the passage, like this, can effectively overcome the downward gravity of mineral powder slurry, made things convenient for the control of mineral powder flow rate of slurry.
Compared with the prior art the present invention has neither can produce ferromagnetic material in the flow process and impacts and the suction induced effect, simultaneously, can not precipitated the advantage that affects again.
Description of drawings:
Fig. 1 is the structural representation of mineral powder sizing material iron removing magnetic material device of the present invention.
The specific embodiment:
Now in conjunction with the embodiments the present invention is done and describes in further detail:
The present invention includes mineral powder sizing material iron removing magnetic substance process, the soft magnetic medium cleaning process, mineral powder sizing material iron removing magnetic substance process is in the bottom exports the vertical non-magnetic passage that is provided with valve soft magnetic medium to be set, at the arranged outside south poles of non-magnetic passage relative permanent magnet or calutron, valve-off, the mineral powder slurry is imported in the non-magnetic passage from the top import of non-magnetic passage, until the mineral powder slurry covers soft magnetic medium and soft magnetic medium is immersed in the mineral powder slurry, open valve, make the mineral powder slurry consistent with the amount of valve discharge from the amount that the import of non-magnetic passage top imports, simultaneously, keep the flow velocity of mineral powder slurry in non-magnetic passage to be lower than 3.5cm/ second, preferably 2cm/ second; The soft magnetic medium cleaning process is to stop to import the mineral powder slurry from the import of non-magnetic passage top, after remaining slurry in passage has been drained from valve, non-magnetic passage is broken away from the relative permanent magnet of south poles or the magneticaction of calutron together with soft magnetic medium, full gate is opened valve, and wash from top to bottom soft magnetic medium by flushing liquor, perhaps by centrifugal method rotation soft magnetic medium, ferromagnetic material on the soft magnetic medium is cleaned out and be excreted on the garbage collection container by valve, clean clean soft magnetic medium and just can again come into operation.Here, stop to import the mineral powder slurry from the import of non-magnetic passage top, when draining remaining slurry, increase the aperture of valve, make the flow velocity of mineral powder slurry in non-magnetic passage maintain 2-3.5cm/ second, to accelerate the cleaning of soft magnetic medium.
