Abstract
The invention provides a smokeless casting process for a gravity casting mould. A blind feeder design is adopted on the gravity casting mould; a water inlet is formed in one end of the gravity casting mould; a primary feeder is arranged in the water inlet; a gas outlet is formed in the gravity casting mould; the blind feeder is arranged in the gas outlet, and is communicated with a tube cavity of the gravity casting mould through a conducting part; the primary feeder and the blind feeder are connected through a feeding channel; the feeding channel is communicated with the primary feeder and the blind feeder through a groove; the cross section area of the groove is matched with that of the blind feeder. According to the smokeless casting process for the gravity casting mould 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 the smokeless pouring technology of a kind of gravity casting mould, 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 the smokeless pouring technology of a kind of gravity casting mould, 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: the smokeless pouring technology of a kind of gravity casting mould, gravity casting mould adopt blind riser to design, described gravity casting mould one end is water inlet, described water inlet is provided with described main rising head, described gravity casting mould is provided with gas outlet, described gas outlet is provided with described blind riser, described blind riser is communicated by the tube chamber of conducting portion with described gravity casting mould, connected by Feeding channel between described main rising head and described blind riser, described Feeding channel is by the through described main rising head of groove and described blind riser, the cross-sectional area of described groove and the cross-sectional area of described blind riser match, the core that the tube chamber of described gravity casting mould adopts cold-box process to be prepared from is cast, described core is wick sand, the one of closing in fat core sand or resin core sand, described blind riser is atmospheric feeder, described main rising head is spherical feeder, after casting terminates, is closed by main rising head.
The smokeless pouring technology of this gravity casting mould 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
The smokeless pouring technology of a kind of gravity casting mould, gravity casting mould adopt blind riser to design, described gravity casting mould one end is water inlet, described water inlet is provided with described main rising head, described gravity casting mould is provided with gas outlet, described gas outlet is provided with described blind riser, described blind riser is communicated by the tube chamber of conducting portion with described gravity casting mould, connected by Feeding channel between described main rising head and described blind riser, described Feeding channel is by the through described main rising head of groove and described blind riser, the cross-sectional area of described groove and the cross-sectional area of described blind riser match, the core that the tube chamber of described gravity casting mould adopts cold-box process to be prepared from is cast, described core is wick sand, the one of closing in fat core sand or resin core sand, described blind riser is atmospheric feeder, described main rising head is spherical feeder, after casting terminates, is closed by main rising head.
The smokeless pouring technology of this gravity casting mould 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.
