Abstract
The invention discloses a method for producing porous brick from the slag coldworked by architectural and sanitary ceramics. The porous brick is characterized in that liquid and solid mixture wastes from cold working of the architectural and sanitary ceramic products are dehydrated and homogenized to obtain solid slag; clay, feldspar (or rock with the feldspar) and carbonate minerals added based on a certain proportion are put into a ball mill and then machined to slurry with proper fineness, then the slurry is dehydrated and doped with granular waste ceramic base, then platy or blocky green brick needed is obtained by the plastic shaping or semi-dry pressing shaping method, the green brick is calcined at the high temperature to become a porous calcined product with certain strength. The method has the advantages of recycling the wastes and complying with environmental protection requirements.
Description
[technical field]
The present invention relates to the processing of ceramic cold-working waste slag and the production method of perforated brick.
[background technology]
The waste residue that all kind cold working of ceramic industry are at present produced all is a useless solid waste, and is very big to environmental influence.For addressing this problem, people utilize above-mentioned waste residue again, as Chinese patent application number is 200410079020.9, name is called a kind of method of utilizing polished waste material production ceramic tile, open day is the patent application of 2005.03.02, it relates to a kind of method of utilizing polished waste material production ceramic tile, waste water with ceramic industry vitreous brick polishing back generation, waste residue compiles, through precipitation, obtain polished waste material after press filtration and the old processing, polished waste material with 10-70%, the 10-35% high temperature sand, the kaolin of 10-35%, the low temperature sandstone batch mixing of 10-30% is gone into wet ball grinding in the ball mill, cross 250 mesh screen residue 0.3-0.8%, it is standby to utilize spray tower to dust in mud after the deironing; Then, utilize ceramic press dry-pressing formed in gained dry powder; Ceramic tile base substrate after the moulding is burnt till in ceramic roller kiln; 1140 ℃-1200 ℃ of firing temperatures; firing period 40-75 minute; this production method is that a large amount of vitreous brick polishing spent material that produce of present ceramic industry are reasonably utilized again, has outstanding advantage at aspects such as save energy, the deadweights of reduction buildings.But also only be that vitreous brick polishing spent material is utilized.
On the other hand, porous ceramics production at present all needs by the organic carrier moulding, airborne easy body volatilization is arranged and the generation porousness in the high-temperature calcination process, and the volatilization of organic carrier can produce gas with foreign flavor; As Chinese patent application number is 98100704.X, patent application day is on March 6th, 1998, denomination of invention is a kind of patent of invention of using the method for fly-ash Preparation sintered perforated brick and hollow brick, it is the processing of grain soil process raw material, compound processing, base, drying, roasting, cooling with 52-75% flyash and 25-48%, and the centre also will make required finished product through repeatedly stirring.Method of the present invention can make sintered perforated brick and the hollow brick that intensity reaches 10.0-30.0MPa.
[summary of the invention]
Purpose of the present invention is exactly the method for the process for producing perforated brick that a kind of ceramic cold-working waste slag with utilization of waste material, compliance with environmental protection requirements is provided.
Technical solution of the present invention is as follows, and its method of utilizing construction sanitary ceramic cold-working waste slag to produce perforated brick comprises that the following technology step is poly-:
