Abstract
The invention discloses a kind of resin sand preparation method, there are following steps to carry out：Step A：Quantitative recycling resin sand and roughing sand are inserted in vibrations disintegrating machine；Step B：Corresponding iron filings are removed using permanent-magnetic iron expeller, obtains unifying the resin sand of particle diameter after centrifugation and filtering；Step C：Filtered resin sand is inserted in bowl-type puddle mixer, quantitative roughing sand, resin and curing agent is added, is mixed through puddle mixer, and add quantitative resin, be prepared into resin sand.The present invention carries out process of refinement by the resin sand for reusing, and through crushing and carries out dedusting by cyclone dust collectors and sack cleaner, is placed into permanent-magnetic iron expeller scrap iron removing and carries out centrifugal treating through regenerating device is centrifuged.Afterwards sold resin sand is obtained in puddle mixer in proportion to the mixing of roughing sand and resin.Resin sand prepared by the program has homogeneous grain diameter, the features such as hardness is big, it is adaptable to which high-grade resin sand is produced.
Description
Technical field
The present invention relates to casting resin sand field, more particularly to a kind of resin sand preparation method.
Background technology
In casting industry, resin sand is one of common used material of making mould, after manufacture mould and modeling, is often needed
Resin sand is reused.In conventional method, artificial treatment is all by by the broken mulling step of resin sand, its treatment
Effect lacks efficiency, and manpower, financial resources, material resources will be more lost.
The content of the invention
The technical problem to be solved in the present invention is：For above-mentioned the deficiencies in the prior art, there is provided a kind of resin sand preparation side
Method.
The present invention solve its technical problem solution be：A kind of resin sand preparation method, it is characterised in that have following
Step is carried out：
Step A：Quantitative recycling resin sand and roughing sand are inserted in vibrations disintegrating machine, is led to its dust after being crushed through vibrations
Cross cyclone dust collectors and sack cleaner absorbs, obtain non-dusting resin sand；
Step B：Corresponding iron filings are removed using permanent-magnetic iron expeller, obtains unifying the resin sand of particle diameter after centrifugation and filtering；
Step C：Filtered resin sand is inserted in bowl-type puddle mixer, quantitative roughing sand, resin and curing agent is added, through mulling
Machine is mixed, and adds quantitative resin, is prepared into resin sand.
As one of preferred technical scheme, it is characterised in that the resin in described step C is furane resins.
As one of preferred technical scheme, it is characterised in that the centrifugation step in described step B is centrifuged by selection by winnowing
Regenerating device is centrifuged.
As one of preferred technical scheme, it is characterised in that described recycling resin sand：Resin：Curing agent is
1：0.8-1.6：0.2-0.8.
The beneficial effects of the invention are as follows：The present invention carries out process of refinement by the resin sand for reusing, through broken
And dedusting is carried out by cyclone dust collectors and sack cleaner, it is placed into permanent-magnetic iron expeller scrap iron removing and is carried out through regenerating device is centrifuged
Centrifugal treating.Afterwards sold resin sand is obtained in puddle mixer in proportion to the mixing of roughing sand and resin.Resin prepared by the program
Sand has homogeneous grain diameter, the features such as hardness is big, it is adaptable to which high-grade resin sand is produced.
Specific embodiment
The technique effect of design of the invention, concrete structure and generation is carried out below with reference to embodiment clear, complete
Ground description, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is of the invention one
Section Example, rather than whole embodiments, based on embodiments of the invention, those skilled in the art is not paying creativeness
The other embodiment obtained on the premise of work, belongs to the scope of protection of the invention.
Embodiment：A kind of resin sand preparation method, it is characterised in that there are the following steps to carry out：
Step A：Quantitative recycling resin sand and roughing sand are inserted in vibrations disintegrating machine, is led to its dust after being crushed through vibrations
Cross cyclone dust collectors and sack cleaner absorbs, obtain non-dusting resin sand；
Step B：Corresponding iron filings are removed using permanent-magnetic iron expeller, obtains unifying the resin sand of particle diameter after centrifugation and filtering；
Step C：Filtered resin sand is inserted in bowl-type puddle mixer, quantitative roughing sand, resin and curing agent is added, through mulling
Machine is mixed, and adds quantitative resin, is prepared into resin sand.
As one of preferred embodiment, it is characterised in that the resin in described step C is furane resins.
As one of preferred embodiment, it is characterised in that the centrifugation step in described step B is centrifuged by selection by winnowing
Regenerating device is centrifuged.
As one of preferred embodiment, it is characterised in that described recycling resin sand：Resin：Curing agent is
1：0.8-1.6：0.2-0.8.
The present embodiment carries out process of refinement by the resin sand for reusing, through it is broken and by cyclone dust collectors and
Sack cleaner carries out dedusting, is placed into permanent-magnetic iron expeller scrap iron removing and carries out centrifugal treating through regenerating device is centrifuged.Afterwards in mulling
In proportion to the mixing of roughing sand and resin in machine, sold resin sand is obtained.Resin sand prepared by the program has homogeneous grain diameter, firmly
The features such as spending big, it is adaptable to which high-grade resin sand is produced.
Better embodiment of the invention is illustrated above, but the invention is not limited to the implementation
Example, those of ordinary skill in the art can also make a variety of equivalent modifications or replace on the premise of without prejudice to spirit of the invention
Change, these equivalent modifications or replacement are all contained in the application claim limited range.
