Abstract
The invention provides a smokeless casting process. A blind feeder design is adopted on a gravity casting mould; the gravity casting mould comprises a blind feeder body with an inner cavity; a gas vent hole communicated with the cavity is formed in the top of the blind feeder body; the blind feeder body is embedded in a metal casing; the gas vent hole is filled with asbestos fibers; the cavity is of an inverted-cone-shaped structure. According to the smokeless casting process disclosed by the invention, most of waste gases are kept in a sand mould, and the emission of waste gases to sites of the operation staff is reduced after the waste gases are processed by environment-friendly sand treatment equipment.
Description
Technical field
The present invention relates to a kind of smokeless pouring technology, belong to field of mechanical technique.
Background technology
Casting industry is as the main source of energy consumption and pollutant emission, and its energy-saving and emission-reduction receive the extensive concern of people.For the situation of casting industry, adopting low emission production technology and equipment directly to reduce discharging, greatly develop Green foundry, is reduce the most direct method of environmental pollution.Pollutant mainly waste gas and dust in production process was all direct discharge originally, and contaminated environment is serious, according to statistics, often produced 1t castings, approximately wanted discharging waste gas 1000-2000 cubic meter, dust 50Kg.If optimized production process and employing sophisticated equipment, the generation of decreasing pollution thing, can greatly reduce environmental pollution.In the casting process that lost foam casting is traditional, focus on die cavity exhaust, rising head is set to open entirely, under the effect of high temperature liquid iron, foam combustion produce large quantity of exhaust gas and dust in line from rising head, environmental pollution is very serious.
Summary of the invention
The invention provides a kind of smokeless pouring technology, the processing stage that disposal of pollutants mainly concentrating on casting pouring and sand, by optimizing pouring technology, can improve casting yield and using environment-friendly equipment, discarded object recycling carrys out decreasing pollution discharge.
For realizing above object, the technical scheme that the present invention will provide is: on gravity casting mould, adopt blind riser to design; Described gravity casting mould comprises the inner blind riser body for cavity, and the steam vent with described cavity connects is arranged at the top of this blind riser body; Blind riser body is embedded in metal-coating, is filled with asbestos fibre in described steam vent; Described cavity is inverted cone-shaped structure.
This smokeless pouring technology that the present invention relates to, waste gas major part rests among molding sand, then through environmental protection sand preparing machine, greatly reduce toxic emission art personnel deeply on-the-spot, adopt blind riser, coarse sand granule moulding, high temperature is smokelessly poured into a mould.
Toxic emission reduces 70%, and dust pollution reduces 67%, and emission reduction effect is remarkable, has stepped solid step forward to Green foundry.Improve the quality of products, unit finished product energy consumption can not only be reduced, and indirectly decrease discharge.Start with from raising casting yield, strict implement production technology, takes charge of product quality severely.Molten iron foundry goods yield rate per ton brings up to 87% by 73%, and product percent of pass brings up to 98.3% by 92%.While enhancing productivity, also indirectly decrease discharge.
Detailed description of the invention
Gravity casting mould adopt blind riser to design; Described gravity casting mould comprises the inner blind riser body for cavity, and the steam vent with described cavity connects is arranged at the top of this blind riser body; Blind riser body is embedded in metal-coating, is filled with asbestos fibre in described steam vent; Described cavity is inverted cone-shaped structure.
This smokeless pouring technology that the present invention relates to, outside the regeneration of antiquated sand energy, after waste residue, dust collection are good, send specialized factory's regeneration, decreasing pollution discharge to a great extent.
Detailed description of the invention of the present invention does not form the restriction to the application's scope; within every spirit in the present invention's design and principle, any amendment that one of skill in the art can make, equivalent to replace and improvement etc. all should be included within protection scope of the present invention.
