Abstract

The invention relates to the waste reusing technology, in particular to a precision casting waste sand reusing method. The precision casting waste sand contains mullite, mullite sand, zirconite and zircon sand. The precision casting waste sand is cleaned, dried, crushed and screened to form aggregate and powder for a fireproof casting material; and a bonding agent and an admixture are added into the aggregate and the powder, and the components are mixed and homogenized to form the fireproof casting material. The method solves the problem that the conventional precision casting waste sand pollutes the environment.

Description

Precision casting waste sand utilizes method again
Technical field
The present invention relates to the waste reutilization technology, relate in particular to a kind of precision casting waste sand and utilize method again.
Background technology
According to statistics, 1 ton of qualified foundry goods of the every production of China produces 1.3~1.5 tons of antiquated sands, and national annual cast waste sand quantity discharged is all more than ten million ton.Present processing mode is arbitrarily to stack or landfill, contaminate environment not only, but also caused the significant wastage of resource.Nineteen ninety-five, country has put into effect People's Republic of China's prevention and control of environmental pollution by solid wastes method (revise in December, 2004 for the first time), encourages, supports scientific research, the technological development of prevention and control of environmental pollution by solid wastes.Requirement takes anti-flying, Anti-lost, antiseep or other to prevent the measure of contaminate environment to various refuses; Must not topple over, stack, abandon, drop solid waste without authorization.Wherein, the processing of cast waste sand has become an instant task, and each big colleges and universities, scientific research institutions and enterprise are all at the treatment technology of seeking cast waste sand, but DeGrain.
The Central China University of Science and Technology, prepared and met the non-burning brick of national standard as main raw material with cast waste sand, solved the difficult problem of cast waste sand land occupation, contaminate environment for DongFeng Automobile Co., Ltd; New big vast steel casting company limited has applied for the patent (CN101033120A) of " prescription of producing concrete brick from foundry waste sand and production method ", this disclosure of the Invention a kind of solid useless with cast waste sand, slag and flyash etc. be that main raw material prepares concrete brick, and design a kind of technical process that can produce the concrete brick that meets national standard JC239-2001.But above patent all is the recycling at quartzy cast waste sand and water glass cast waste sand, for the precision casting industry with mullite, not come sand and zircon, zircon sand be that the precision casting waste sand recycling of main component does not then have relevant report.
Summary of the invention
In order to overcome above-mentioned defective, the technical problem to be solved in the present invention is: at existing depleted precision casting waste sand problem of environment pollution caused, provide a kind of precision casting waste sand to utilize method again.
In order to overcome the defective that exists in the background technology, the technical solution adopted for the present invention to solve the technical problems is: a kind of precision casting waste sand utilizes method again, contain mullite, Mo Laisha, zircon and zircon sand in the precision casting waste sand, precision casting waste sand through clean, dry, pulverize and screening is mixed with the aggregate and the powder of refractory material casting material, add wedding agent again and admixture is mixedly made into refractory material casting material.
Precision casting waste sand of the present invention utilizes method again, and concrete preparation method is as follows:
A. with precision casting waste sand through washing, be dried to moisture and be not higher than 1% standby;
B. the standby antiquated sand with step a passes through the jaw crushing crusher machine, and powder adopts magnetic separation, the deironing of pickling mode;
C. the standby raw material of step b being sieved grain composition puts in storage respectively;
D. the standby raw material with step c is mixed with the aggregate and the powder of refractory material casting material according to the certain granules level, and adds wedding agent and admixture mixing and carry out homogenizing.
Precision casting waste sand of the present invention utilizes method again, and described wedding agent is at least a of pure calcium aluminate cement, silicate cement, beta crystal aluminium sesquioxide, silicon sol or water glass.
Precision casting waste sand of the present invention utilizes method again, and described admixture is at least a of sodium lignosulfonate, tripoly phosphate sodium STPP, macrogol or Sodium hexametaphosphate 99.
Precision casting waste sand of the present invention utilizes method again, and the mass mixing ratio example of aggregate, powder, wedding agent and admixture is 30~40: 40~50 in the described steps d: 10~15: 0.2.
Beneficial effect: by suitable treatment process, the precision casting waste sand resource utilization is used, turned waste into wealth, prepare the lower refractory material casting material of production cost.Fundamentally solved precision casting waste sand stacking, problem of environmental pollution that landfill brought, made its economic environmental protection burden become the profit point that enterprise Green is made, promoted the circulation low-carbon economyization of casting industry from original casting industry.In addition, be main raw material owing to adopt solid waste, reduced the consumption of refractory materials production to natural mineral, saved the Mineral resources of China, promoted the sound development of refractories industry.
