Embodiment 1

[0031] This embodiment provides a vacuum filtration recovery and reprocessing process for aerospace titanium alloy casting model wax, which specifically includes: firstly, the recovered wax is initially screened, and the recovered wax containing impurities is picked out with the naked eye, because wax with many impurities, The processing cycle becomes stronger; then use a wax crusher to break it into fixed-sized block wax, which is easy to melt and can reduce various energy consumption. Usually, the melting process of recovered wax is very long, and the water in the recovered wax is recovered. It will evaporate a little bit during the melting process. Pay special attention to the fact that the melting tank should not be too full when adding wax for the first time, because the recycled wax with a large amount of water will form a roll in the tank when it melts to a certain extent, and it is easy to make the melting tank The wax in the tank boils and spills out of the tank, causi...

Embodiment 2

[0035] The vacuum wax pump used in Example 1 is further introduced, which includes: a handle, a motor, a coupling, a heating mantle, a gear pump, a feed inlet, a base, a support plate, a backing plate, and a universal wheel; The heating mantle includes an upper shell and a lower shell, and a joint for connecting electric wires is arranged on the lower shell. The gear pump is placed between the upper shell and the lower shell. The gear pump is connected with the motor through a coupling. One end of the gear pump is provided with a feed port, which is connected to the feed pipe, and the other end of the gear pump is provided with a discharge port, which is connected to the discharge pipe; the base and the backing plate are fixed on On the support plate, a heating cover is provided on the base, and a motor is provided on the backing plate; The sides are respectively provided with side plates, and the tops of the side plates are connected with the support plate.

Embodiment 3

[0040] The filter tank used in Example 1 is further introduced. The structure of the filter tank used in the third filtration is the same, and a pressure ring, a filter paper, a support ring with a round hole, and a conical tank are all provided inside it. The tank is located at the lower part of the filter tank, and a support ring with round holes is arranged on the conical tank, the filter paper is located on the support ring with round holes, and the pressure ring is pressed on the outer periphery of the filter paper.

[0041] Preferably, handles are provided at both ends of the pressure ring.

Abstract

The invention discloses a vacuum filtering, recovering and reprocessing technology for aviation titanium alloy cast model wax. The technology concretely comprises the following steps: S1, screening; S2, breaking the wax by a wax crusher to form wax blocks with a fixed size; S3, placing and melting a certain amount of the wax blocks in a melting tank, and heating the wax after the recovered wax isthoroughly melted; S4, performing precipitation layering, diverting the wax recovered from the upper part of the melting tank into a primary filtering tank by a diverting valve outside the body of thetank a certain time later according to the formed layering condition, and performing precipitation processing on the remaining recovered wax in the melting tank; and S5, pumping the processed recovered wax into filtering tanks through a vacuum wax pump, pumping the three-stage filtered wax into a heat insulation box by the vacuum wax pump, and performing heat insulation on the wax for later use.The technology used to process the wax has the advantages of fullness in waste wax recovery, avoiding of a lot of wastes, and saving of cost, manpower and material resources, and the recovered wax canbe reutilized to improve the utilization values.

Description

technical field [0001] The invention relates to a process for recovering wax, in particular to a process for recovering and reprocessing aviation titanium alloy casting model wax through vacuum filtration. Background technique [0002] In the production process of investment casting, wax plays a great role in the manufacture of wax patterns, and the amount of wax used is large, and the wax is recycled in the actual production process. Therefore, the treatment of recovered wax has received widespread attention. [0003] Recycled wax is wax that has been used or used many times and is reprocessed. It contains more special impurities and water than new materials. Therefore, in processing engineering, the equipment used in special links has become relatively complicated. Contents of the invention [0004] The invention provides a vacuum filtration recovery and reprocessing process for aviation titanium alloy casting model wax. Using this process to process wax material can f...
