Abstract
The utility model relates to a high gradient magnetic field solid/liquid separator, comprising a magnetic field of a fixed permanent magnet and a stainless steel slot arranged in the magnetic path of the magnetic field of the fixed permanent magnet. The stainless steel slot is vertically stacked with multi-layer iron nets with vertical magnetic force lines, a slot bottom of the stainless steel slot is provided with a liquid inlet, and the upper part of a side surface is provided with a liquid outlet. Owing to all the multi-layer iron nets stacked in the slot being vertical to the magnetic force line, the magnetic field strength is high and uniform, and the utility model can continuously separate liquid and solid in leaching out liquid. The utility model has the advantages of simple structure, convenient operation and high separation rate and can get completely separation of 100%.
Description
The utility model relates to a kind of high-gradient magnetic field solid-liquid separator that is used for separating the contained weak magnetic corpuscular of leachate.
Existing solid-liquid separating method has sedimentation, filtration method, centrifugal process, adds flocculant and magnetic separation method.Though these solid-liquid separating methods are widely used, for high temperature, high viscosity, severe corrosive or contain the separation of the complex salt leachate of weak magnetic corpuscular, but can't reach ideal effect.Such as, to solid content 80g/L, slurry specific gravity 1.5, viscosity 15 centipoises, particle average grain diameter 3-50 micron and need are incubated 110 ℃ complex salt leachate, need 16 hours with the sedimentation separation, also, still contain 2% solid particle in the clear liquid owing to the inhomogeneous fine grain Brownian movement that causes in temperature field in the settling tank; Because the big particle diameter of this complex salt leachate viscosity is little, general filtration method is difficult to realize the Separation of Solid and Liquid of its leachate; Separate this complex salt leachate with centrifugal process, solid content still is 5% in the clear liquid under the 5000rpm rotating speed after centrifugal; General electromagnetism separates the acceleration sedimentation still needs 4 hours; Because of the complex salt leachate is a concentrated base high temperature, separate with adding the flocculant method, flocculant wherein can be decomposed, and can't realize flocculation.
At present, the better simply solid-liquid separator of a kind of structure is arranged, can be used for separating above-mentioned high temperature, high viscosity, severe corrosive or contain the complex salt leachate of small weak magnetic-particle, its structure is: put into a stainless steel tank in a fixed permanent magnet magnetic field magnetic circuit, put into irregular steel wire group in the stainless steel tank, steel wire group has magnetic under the effect in magnetic field, when putting into above-mentioned complex salt leachate in the stainless steel tank, weak magnetic corpuscular wherein just can be adsorbed on the silk hair of steel wire group, reaches the Separation of Solid and Liquid of leachate.But the steely wool in this separator only has that part of cutting magnetic line just can adsorb weak magnetic corpuscular in the leachate, so its absorption affinity is limited, separating effect is undesirable.
The utility model purpose is to overcome the deficiency of above-mentioned solid-liquid separator, and provide a kind of weak magnetic corpuscular in the leachate is separated fully, the high-gradient magnetic field solid-liquid separator that separation rate is high.
Another purpose of the present utility model is to provide a kind of high-gradient magnetic field solid-liquid separator that can separate weak magnetic corpuscular in the leachate continuously.
The utility model embodiment is as follows:
The high-gradient magnetic field solid-liquid separator that the utility model provides, comprise a pair of fixed permanent magnet and the stainless steel tank that is arranged in fixed permanent magnet magnetic field magnetic circuit, it is characterized in that: the vertical iron net that stacks the vertical magnetic line of force of multilayer in the stainless steel tank, it is different with the thickness of iron net and do not wait that the quantity of iron net is parallel to width on the magnetic line of force direction according to stainless steel tank, and be the best to be full of stainless steel tank, distance between fixed permanent magnet N and the S magnetic pole is 1-5 centimetre, and magnetic field intensity is the 1000-8800 oersted; In order to reach the continuous separation of contained weak magnetic corpuscular in the leachate, the utility model is provided with an inlet at stainless steel tank bottom land, and the top, a side of stainless steel tank parallel permanent magnets magnetic line of force direction is provided with a liquid outlet; In order to prevent in the separation process concentrated base because temperature is crossed low and condensation, stainless steel tank is parallel on the cell wall outer surface of magnetic field magnetic line direction heat-insulation layer is set.
The high-gradient magnetic field solid-liquid separator that the utility model provides, because all vertical magnetic line of force of the vertical multilayer iron net that stacks in the stainless steel tank, its magnetic field intensity is high and even, can reach the purpose of the weak magnetic corpuscular in the efficient absorption leachate, so this high-gradient magnetic field solid-liquid separator separation rate height; In addition, because stainless steel tank bottom land is provided with an inlet, the top, one side of stainless steel tank parallel permanent magnets magnetic line of force direction is provided with a liquid outlet, so the utility model can be accomplished the continued operation of leachate Separation of Solid and Liquid, simple in structure, easy to use, and the separation rate height, separation rate almost can reach 100% separation fully.
