Abstract
A microporous ceramic filter plate for solid-liquid separation of slurry material is composed of two microporous ceramic filter sheets. Each filter sheet consists of the base layer prepared from ceramic particles containing corundum particles (40-500 microns), and the surficial layer prepared from ceramic microparticles containing corundum particles (0.5-25 microns). Its advantages are high strength, high filter performance, low flow resistance, high resistance to acid corrosion, low cost and long service life.
Description
The present invention relates to a kind of Microporous Ceramic Filter Plate And Preparation Method that is used for slurry material solid-liquid separation, the Microporous Ceramic Filter Plate And Preparation Method of using in particular for black, nonferrous mine beneficiation concentrate dewatering and filtering.
Present capillary ceramic plate has two types, a kind of is to adopt one-time cast-forming, and micropore is uniform isometrical hole on thickness direction, and another kind is the second pouring moulding, pour into the hollow layer structure earlier, sinter into behind hollow layer with big ceramic particle pouring filling again; Capillary ceramic plate is to use the wicking action principle, and under the water-wet state, capillary action can be passed through water, gas and solid particulate can not pass through, and the quality of screen plate filter effect is relevant with the micro-pore diameter size, and the more little filter effect of micro-pore diameter is good more, but micropore is more little, and flow resistance is then big more.One-time cast-forming, micropore is uniform isometrical hole on thickness direction, be not suitable for separating the concentrate material of the above granularity of 200 orders, because this capillary ceramic plate will satisfy filter effect, need make very little micropore, will satisfy requirement of strength simultaneously also will increase thickness, and thickness increases, flow resistance is big, and discharge capacity is low; In addition, one-time cast-forming, defectives such as pin hole, tiny crack appear in screen plate surface easily, cause strength degradation; The second pouring moulding, can overcome above-mentioned shortcoming, satisfying filter effect and do not increasing under the prerequisite of flow resistance, improve screen plate intensity, as Chinese patent: a kind of ceramic filtering board for separating solid from liquid and preparation method (patent No. 98111184) adopt aggregate and base-material to mix, aggregate is selected corundum and/or mullite and/or flint clay and/or carborundum, base-material is aluminum oxide and/or clay and/or feldspar, burn earlier and form the hollow layer structure, the big ceramic particle made from above-mentioned aggregate and base-material again, filling sinters supporter in hollow layer, and the supporter outside surface adsorbs one deck mud sintering again under negative pressure, though this capillary ceramic plate can form the hole gradient, but the hollow layer structural walls of this method cast earlier is thin to be difficult for reaching requirement, and tamp the centre, do not have the drainage passage, flow resistance is also bigger.Present capillary ceramic plate base material adopts high temperature agglomerated materials such as lime carbonate more, and lime carbonate is corroded in acidic medium easily, causes screen plate working strength in acidic medium to reduce, and phenomenons such as easy explosion occur.
The purpose of this invention is to provide a kind of slurry material solid-liquid separation that can be used in, good filtration effect, filter plate intensity height, the Microporous Ceramic Filter Plate And Preparation Method that flow resistance is little, manufacture craft is simple and direct.
