Description
Technical field
The present invention relates to the hot investment casting field, relate in particular in the full form casting process a kind of recycling wax dewatering process and equipment after wax-pattern dewaxed.
Background technology
After wax-pattern dewaxes in dewaxing kettle, the wax that melts just reclaims by recovery channel, because dewaxing kettle is to adopt the steam of HTHP to dewax, mix with wax so must have a lot of water, so must remove water treatment to the wax after reclaiming.
Traditional dewatering process all is to adopt about 180 ℃ high temperature to dewater, and this high temperature dewatering process destroys too large to the character of wax, when wax recycles more than 3 times, the quality of recycling wax just can not be guaranteed, thereby affect Product Precision, the product fraction defective reaches 20%, and rehabilitation cost is high.Simultaneously, adopt the recycling wax water removal device complex structure, expensive of this dewatering process.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly can improve the recycling wax dewatering process that recycling wax recycles number of times.
Corresponding therewith, another technical problem that will solve of the present invention provides a kind of recycling wax that can improve and recycles number of times, recycling wax water removal device simple in structure.
With regard to the recycling wax dewatering process, the method that the present invention solves the problems of the technologies described above is: the temperature for removing water of recycling wax is 100-110 ℃, and the time of dewatering is 3-5 hour.
As the preferred version of recycling wax dewatering process of the present invention, the temperature for removing water of recycling wax is 105 ℃, and the time of dewatering is 4 hours.
Adopt above-mentioned technique, but the access times of circulation recycling wax be promoted to more than 10 times, reduce the generation of slop wax, effects of energy saving and emission reduction is obvious, the Product Precision yields promotes 20%.
With regard to the recycling wax water removal device, the present invention is that the equipment that solve the technical problem comprises storage wax chamber, inwall, heat-insulation layer, the recycling wax inlet duct, can use wax outlet conduit and drainage pipeline, described drainage pipeline is positioned at the below that can use the wax outlet conduit, described inwall adopts metal material to make, one deck heat conduction oil reservoir is arranged between described inwall and the heat-insulation layer, described heat conduction oil reservoir is in-built electric heating tube, described electric heating tube links to each other with temperature controller by electric heating circuit, described storage wax is equipped with temperature sensor in the chamber, described temperature sensor links to each other with temperature controller by temperature sensing circuit, and described temperature controller can be according to the temperature automatic control electrical heating pipe of recycling wax in the storage wax chamber.
Adopt the equipment of said structure, by electric heating tube the heat conduction oil reservoir is heated, and be controlled in the suitable scope by the temperature of temperature controller with recycling wax, thereby the character that guarantees recycling wax is not destroyed, and improves to recycle number of times.
As the further improvement of recycling wax water removal device of the present invention, described storage wax is equipped with filter in the chamber.
As further improving again of recycling wax water removal device of the present invention, described filter is three-stage filtration.
By above-mentioned improvement project, can when recycling wax is dewatered, some impurity can also be filtered.
