Description
Technical field
The present invention relates to the regeneration field of ceramic core depoling waste water and waste liquid, refer to that a kind of alkali corrosion method removes the waste water and waste liquid reclaim equiment of precision castings ceramic core especially.
Background technology
Ceramic core is the chovr body for the formation of precision castings inner-cavity structure in full form casting process, with the dimensional precision of outer mould and formwork common guarantee precision castings cavity, be applicable to precision castings die cavity that is complex-shaped or that be not easily shaped, it is a kind of energy Simplified flowsheet difficulty, reduce costs, improve the special process means of job efficiency.
At present, usually use alkali corrosion method to the depoling of precision castings ceramic core, such as normal pressure molten caustic soda cooking method, normal pressure alkaline solution alkaline-heating method etc., depoling can produce a large amount of waste water and waste liquid, is mainly derived from two aspects:
1) by alkali corrosion method to the waste liquid produced after ceramic core depoling; 2) with the waste water that the ceramic mud cleaning cast(ing) surface after clean water depoling produces; 3) ceramic mud.Pertinent literature shows, above-mentioned waste water and waste liquid is that alkalescence is high, rich conjunction sodium, potassium oxyhydroxide, close the harmful liquid having the radioelement such as quantitative uranium, vanadium, hafnium, complicated component, configurations simultaneously, if recycle not in time and discharge as industrial refuse, will work the mischief to people, animal, threat to life property safety, causes great destruction to water and soil resources environment simultaneously.
Summary of the invention
For the deficiencies in the prior art; the invention provides the waste water and waste liquid reclaim equiment that a kind of alkali corrosion method removes precision castings ceramic core; solution alkali corrosion method is to the regeneration problem of the waste water and waste liquid that ceramic core depoling produces; efficient recovery waste water, waste liquid and ceramic mud; thus turn waste into wealth; people and animals are avoided to be injured, protection Land Environment resource.Waste water and waste liquid after this device processes and ceramic mud can reach zero release.
The technical solution adopted in the present invention is as follows: a kind of alkali corrosion method removes the waste water and waste liquid reclaim equiment of precision castings ceramic core, comprise pending pond, clean clean pond, filtering net, pipeline, ball valve A and ball valve B, wherein, pending pond is connected by pipeline with clean clean pond, near pending pond place mounting ball valve A on pipeline, near clean clean pond place mounting ball valve B, ball valve A connects pressurized air, and filtering net is positioned at pending pond and is connected with pipeline, it is characterized in that: position, described pending pond is higher than clean clean pond, and filtering net is inverted in pending pond.
Beneficial effect of the present invention is: the reverse work principle of filter of this equipment utilization antigravity, treat waste water and waste liquid in treating pond and ceramic mud carries out solid-liquid separation, available clear water after regeneration or alkali lye are put into clean clean pond by pipeline, solid sediment is then filtered net filtration, stay in pending pond in order to again reclaiming, thus turn waste into wealth, realize the regeneration of waste water, waste liquid and the ceramic mud that alkali corrosion method produces ceramic core depoling, prevent water and soil resources environment contaminated, avoid person poultry poisoning, accomplish waste water and waste liquid zero release.
Accompanying drawing explanation
Accompanying drawing of the present invention is described as follows:
Fig. 1 is structure principle chart of the present invention.
1 pending pond; 2 clean clean ponds; 3 pipelines; 4 ball valve A; 5 ball valve B; 6 filtering nets; 7 pressurized air.
Embodiment
