Abstract

The invention discloses an electric dehydration and deslagging method and device for investment casting pattern materials. According to the method, an electric field force generated by a high-voltage electric field is used for performing electrophoresis coalescence, dipole coalescence, vibration coalescence and the like on water drops in the smelted pattern materials, so that the small water drops are accumulated to form water drops with great grain diameters, which are then easily deposited in and separated from the pattern materials, and meanwhile, solid impurities or soluble salts dispersed in the water drops or adsorbed to the surfaces of the water drops are deposited together with the water drops so as to realize dehydration and deslagging of the pattern materials. A control system controls heating power and regulates feeding and discharging flow and electric field parameters according to parameters including temperatures, pressures, a wax-water interface level, discharged material water content and the like of the treated pattern materials, and thus continuous and stable operation is guaranteed. According to the electric dehydration and deslagging method and device for the investment casting pattern materials, the disadvantages of long treatment time, high energy consumption, low efficiency, large occupied space and the like of a traditional device are overcome, and the energy-saving, efficient, continuous and stable dehydration and deslagging process of the pattern materials is realized.

Description

Technical field [0001] The invention belongs to the technical field of solid-liquid and liquid-liquid separation, in particular to an electric dehydration and slag removal treatment method and device in the process of investment casting mold material recovery, which is suitable for the dehydration and slag removal of different types of investment casting mold materials Treatment solves the problems of long treatment time, high energy consumption, low efficiency, and large equipment occupation space of the existing dehydration and deslagging treatment method. Background technique [0002] In the investment casting process, the lost wax mold (dewaxing) is one of the main processes. There are many dewaxing methods, such as organic solvent method, hot water dewaxing method, high pressure steam dewaxing method, flash dewaxing method, microwave dewaxing method, hot sand dewaxing method and so on. The most widely used method is the high-pressure steam method, which is also the main dew...
