Description

Technical Field

[0001] The utility model relates to the technical field of dewaxing kettles, in particular to an energy-saving dewaxing kettle. Background Art

[0002] Dewaxing kettle is a precision casting equipment, which is also called lost wax casting. Its products are precise, complex, and close to the final shape of parts. They can be used directly without processing or with little processing. Therefore, investment casting is an advanced process of near net shape. Compared with traditional sand casting process, the casting size obtained by precision casting is more accurate and the surface finish is better. Among them, the more commonly used is investment casting, also known as lost wax casting: select suitable investment material (such as paraffin) to make investment mold; repeat the process of applying refractory coating and spreading refractory sand on the investment mold, harden the shell and dry it; then melt the internal investment mold.

[0003] After searching, the Chinese patent announcement number is: CN214920249U, which discloses an energy-saving dewaxing kettle. The patent uses a kettle body, an exhaust pipe is provided on the outer tank of the kettle body, and a first valve is connected to the exhaust pipe. It also includes a water supply tank, and the water supply tank has an inlet end and a water outlet end. The water outlet end is connected to the inner part of the outer tank through a conduit. A ventilation pipe is provided in the water supply tank, and both ends of the ventilation pipe extend to the outside of the water supply tank. The output end of the first valve is connected to the air inlet end of the ventilation pipe. When pressure relief is required, the first valve is opened to allow the steam in the kettle body to be transported to the ventilation pipe. When the steam passes through the ventilation pipe, it can heat the water in the water supply tank. After being heated to a certain temperature, the hot water is transported to the outer tank, thereby realizing the reasonable reuse of resources, avoiding resource waste, and saving energy and protecting the environment.
