Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wax-water separation equipment, in particular to a slightly negative pressure steam heating wax-water separator. Background Art
[0002] At present, the domestic precision casting industry has been recycling and reusing the wax, the raw material of wax mold, which is one of its main processes. During the production process, the wax liquid is mixed with water in different proportions, and the water is extremely harmful to the reuse of the wax liquid. The main harm is that it affects the shrinkage of the wax mold's geometric dimensions and reduces the wax mold's strength.
[0003] For a long time, the traditional wax-water separation equipment has adopted a heating tube with heat transfer oil as the heat source and equipped with a stirring device. The process is to introduce the wax liquid mixed with water into a container, heat it to 110-130°C, and use the device to stir it fully, so that part of the water in the wax liquid evaporates due to the high temperature, and the other part sinks to the bottom of the container because the specific gravity of water is greater than that of wax liquid. The whole process takes 8-12 hours, so the container is always in a heating state. The heat transfer oil is a flammable and explosive substance, and there are safety hazards in long-term operation.
