Description
Technical field
The utility model relates to a kind of magnetic separation dehydration equipment, and especially a kind of embedded magnetic separates filter pressing dehydrator, utilizes magnetic force that magnetic pulp water or magnetic material are separated thickening, belongs to magnetic separation dehydration technique field.
Background technology
Aspect ore deposit choosing and dense media coal washing, the drum-type magnetic plant is adopted in the sorting of magnetic material, thickening more.In recent years both at home and abroad in Industrial Wastewater Treatment such as metallurgical waste water, machined waste water, the magnetically separating and purifying technology also is applied; Simultaneously, magnetic force squeezing thickening technology is also in development.Obviously; Utilize magnetic separation technique that moisture magnetic pulp water or magnetic material are separated thickening, have more specific aim, can realize continuous operation compared with technology such as traditional plate compression, belt press filtration, centrifugal dehydrations; Reduce floor space; Reduce investment, operating cost, reduce energy consumption, so the magnetic separation dehydration technique has bright development prospect.
Existing magnetic separation thickening equipment utilizes the magnetic tube that magnetic slag is adsorbed on the magnetic cylinder surface, and along with the rotation of magnetic cylinder, the pressure roller that is arranged at the magnetic cylinder top is magnetic cylinder surface slag extrusion dehydration, scrapes from magnetic cylinder surperficial with the scraper plate slag that will dewater then.This kind equipment leans on magnetic force that magnetic pulp water or magnetic material are separated thickening, has effectively utilized the magnetic characteristics of pending thing itself, than the thickening technology occupation of land of routine lack, invest low, operation maintenance is simple, energy consumption is low.But existing magnetic force thickening technology mainly is that dehydration equipment is pressed in the magnetic roll-in, and weak point is: launch outside tube in magnetic cylinder magnetic field, and magnetic slag is attracted to the magnetic cylinder outer surface, and correspondingly, pressure roller and scum board all are arranged on the magnetic cylinder outer surface.The unfavorable effect that such structure is brought is; The water outlet of pressure roller and magnetic cylinder extruding can not in time be drained; Come slag to mix but return along the magnetic cylinder surface, as long as therefore have water to be forced out, even multistage magnetic cylinder squeezing is set with follow-up; It is to mix the crush zone that saturated state gets into pinch roller and magnetic cylinder with water, so to be difficult to make the moisture content of slagging tap to drop to desired level all the time that slag is come in each grade crush zone follow-up.This respect is different from belt filter press, thus the latter can with each time press filtration water in time discharge not with follow-up come slag to mix again so the moisture content of slagging tap low.The slag tap solution one of moisture content of existing reduction is the thrust that increases pressure roller, but the corresponding again short problem of pinch roller life-span of bringing of the increase of thrust; Perhaps adopt multistage magnetic roll-in to press, because the water problems of returning of each grade is difficult to overcome, it is still higher to extrude the slag moisture content, has also increased cost of investment simultaneously; The way of also useful increase magnetic field intensity, but this mainly is the slag-containing rate that has reduced water outlet, and the moisture content of slagging tap is not had obvious benefit, because the moisture content of slagging tap depends primarily on the squeezing effect.The magnetic force press dewatering practice for many years of metallurgy industry magnetic sludge also shows; Existing magnetic force press dewatering equipment; No matter be one pole magnetic roller or multistage magnetic roller, dehydrating effect is all undesirable, and the moisture content of slagging tap is all apparently higher than traditional plate compression, centrifugal dehydration etc.On the other hand, the magnetic cylinder two ends of existing magnetic force squeezing dewatering machine are all sealed and space, magnetic current road is little, and the equipment capacity of resisting impact load is very low, and the variation of pulp water amount is easy to cause overflow, causes device context to be polluted.
