Abstract
The invention relates to a filter in metal smelting process, in particular to a duplex-structure foamed ceramic filter plate, a manufacture method thereof and an aluminum melt filtering device. The duplex-structure foamed ceramic filter plate is prepared by mixing the following raw materials in parts by weight: 35-40 parts of aluminum dihydrogen phosphate, 1-2 parts of pyrogenic silica, 1-2 parts of kaolin, 1-2 parts of aerogel, 55-60 parts of Alpha alumina, 1-2 parts of defoamer, 0.5-1 part dispersant, and the like. The invention is mainly characterized in that the foamed ceramic filter plates with different hole meshes are stacked and combined into a whole by utilizing the manufacture characteristics of the foamed ceramic filter plates to produce a double-layer or multilayer stacked combination body containing the foamed ceramic filter plates with different hole meshes, and then, the stacked combination body is arranged in a filter box body for filtering aluminum melt. As the stacked conjoined structure is adopted, the air exhaust flow and the plate body floating phenomenon in the original method are reduced, and the multi-stage filtration is easy to realize; therefore, the invention really realizes the double-level or multi-level aluminum melt filtering method which has high precision and efficiency and is economic and convenient.
Description
Technical field
The present invention relates to the filter of metal smelt, refer in particular to a kind of duplex-structure foamed ceramic filter plate and preparation method and aluminum melt filtering device.
Background technology
Perfect along with science and technology development and process equipment, people filter aluminum melt and have proposed more requirement, are pursuing high accuracy, and in the time of high efficiency process, people require to provide operation easier, filter the lower filter method of cost.Existing utilize the two-ply foam ceramic filter plate to carry out bipolar filter method to improve the inclusion removal rate significantly; The possibility that more stable filtration treatment-minimizing impurity passes through; And its cost is low; Compact to design; The production flexibility is strong-uses neatly according to quality requirement twoly to become different holes purpose to filter.Yet we have found that also there is certain defective in this filter method in process of production, owing between bilayer of installing in the existing Rose Box or the multi-layer ceramics filter certain space is arranged, must take exhaust flow path during filtration, make filtration system become loaded down with trivial details; And do not drain gas owing to be compressed between plate and the plate, and often cause the floating of top filter, for filtering, aluminum melt brought inconvenience.Even owing to air existence between plate has limited the flow of aluminum melt.Moreover, because the space between the double medium filtration plate in the existing Rose Box exists, the filter of lower floor is not easy to accept the heat radiation of heating element heater above the casing, cause the temperature of lower plywood to be difficult to reach the preheat temperature requirement, must increase special gas preheating to lower plywood and make up, thereby cause the rising of filtering cost.
Summary of the invention
The objective of the invention is to be improved, a kind of duplex-structure foamed ceramic filter plate and preparation method and aluminum melt filtering device are provided at shortcoming that exists in the background technology and problem.
Filter of the present invention is to be made by the raw material of following weight portion:
Aluminium dihydrogen phosphate 35-40 part, gas-phase silica 1-2 part, kaolin 1-2 part, aeroge 1-2 part, Alpha's aluminium oxide 55-60 part, defoamer 1-2 part and dispersant 0.5-1 part etc. mix.
The preparation method of filter of the present invention:
Adopt foam as mould, aluminium dihydrogen phosphate, gas-phase silica, kaolin, aeroge, Alpha's aluminium oxide, defoamer and dispersant etc. are mixed and made into slurry, again the slurry that mixes is squeezed into foam mold, filter after the moulding is toasted, filter after will toasting again carries out sintering, foamed ceramic filter plate.
The structure of filter of the present invention is:
The filter of being made by at least two layers of foam ceramic material is arranged on a bottom that can hold the aluminum melt space, and the foamed ceramic filter plate of aluminum melt by duplex filters;
The top of the described foamed ceramic filter plate that holds the aluminum melt space that is arranged on is provided with the import chute, and the foamed ceramic filter plate below is provided with the outlet chute, and aluminum melt flows out after infiltering foamed ceramic filter plate;
Describedly can hold the space of aluminum melt and the foamed ceramic filter plate of duplex is arranged in the casing of a metal shell, casing one side is provided with the import chute.Opposite side is provided with the outlet chute.
Advantage of the present invention and beneficial effect:
The present invention mainly is making characteristics of utilizing foamed ceramic filter plate, different holes purpose foamed ceramic filter plate piled up be combined into one, be made into the foamed ceramic filter plate that contains different holes purpose bilayer or multilayer and pile up combination, attach it to then in the filter box aluminum melt is filtered.The characteristics of this method maximum are two different holes purpose foamed ceramic filter plates in the former Rose Box to be stacked into one with regard to manufacturing aluminum melt is carried out double-stage filtering when making.Even multiple different holes purpose foam can be piled up and manufacture compound foamed ceramic filter plate and carry out multistage filtering.
The present invention can improve clearance significantly; The possibility that more stable filtration treatment-minimizing impurity passes through; By the filter that uses the aperture to reduce successively, two one-tenth or the multiple filtration system field trash that can dam to greatest extent; Compound foamed ceramic filter plate is easy to use simultaneously; Compact to design; The production flexibility is strong-and use the filter of bilayer or different hole orders of multilayer and thickness to pile up combination neatly according to quality requirement; Owing to be that stacked structures improves the tear fracture rate and allows safer, easier clean residual aluminium and the cleaning filter box put of operating personnel, reduce the metal temperature loss; Simultaneously also reduced heating surface (area) (HS, solved the phenomenon of bottom filter heat supply deficiency in the current methods well, for the energy has been saved in production.Simultaneously owing to be the stack connecting body structure, economization exhaust flow path and the plate body hydro-planing in the former method.And realize multistage filtering easily.Therefore, the present invention has really realized high-precision, high efficiency, economical and convenient bipolar or multistage aluminum melt filter method.
