Specific implementation mode
Below in conjunction with Figure of description, the invention will be further described.Following embodiment is only used for clearly
Illustrate technical scheme of the present invention, and not intended to limit the protection scope of the present invention.
Embodiment 1
A kind of aero titanium alloy casting pattern wax vacuum filter recycling re-treating process is present embodiments provided, it is specific
For：Recycling wax is done to preliminary screening first, is picked away the recycling wax containing impurity by naked eyes, because more than impurity
Wax, process cycle become strong；Then broken wax machine is used, the blocky wax of fixed size is broken into, convenient for melting, and can be reduced each
Item energy loss, it is generally the case that the melting process of recycling wax is very long, the moisture in recycling wax, can be in melting process a bit
Point evaporation, pays special attention to, and melting tank is not expired very much when first time plus wax, because of the recycling wax that moisture is larger, is melted to
Rolling can be formed in tank to a certain degree, it is easy to so that the wax in melting tank is boiling over outside tank, be caused very to equipment and circuit
Major injury, after recycling wax in tank is thoroughly melted well, most of moisture is also evaporated totally, is only left a little moisture, this process
There is still a need for heating, the larger impurity of proportion such as fine sand can be precipitated, after certain time (forming layering), outside tank body
Flow divider is diverted in filtering tank, and so-called flow divider is after being melted well according to wax, and the delamination of formation first filters top,
It remaining recycling wax, then is precipitated, if melting tank is more, wax can be utilized to pump, all remaining wax materials are uniformly placed on
In one tank, process in batches.To the last the remaining wax material that cannot be reprocessed in tank is cleaned out, then is added again,
The top of only tank has flow divider, lower half portion not to have, it is necessary to be extracted by vacuum pump.
It especially emphasizes, filter paper is mainly process by pure plant fiber, the pure white exquisiteness of quality, flat appearance, thickness
Uniformly, intensity is high, and for the recycling wax of prefiltration, the recycling wax after also using thickening type filter paper, filtering good can be by true
Sky pump is directly drawn into secondary filter tank, at this moment we with high-precision filter paper, material composition is excellent by purified cotton, import
Matter wood pulp, food industry filter aid diatomite, pearlite filtering aid, wet strength agent for paper making (<1.5%), high pure cellulose, into
Mouth polyvinylpyrrolidone is refined to be formed.The channel of its three-dimensional space makes have thousands of square metres in every square metre of filter area
