Wax recovery treatment system and method applied to precision casting

Abstract

The invention provides a wax recovery treatment system and method applied to precision casting. The system comprises a dewaxing kettle, a wax-water separation device, a dewatering and standing device,a steam generation device and a pneumatic wax pumping cylinder. The method comprises a dewaxing step used for dewaxing a mold shell, a wax-water separation step used for carrying out precipitation separation on the wax water generated by the dewaxing kettle, and a dewatering and standing step used for dewatering and standing the wax liquid. In the wax-water separation step, wax water generated bythe dewaxing kettle is subjected to preliminary precipitation for a certain period of time, so that the wax water is separated from sand powder, and then the wax water is heated to remove water. In the dewatering and standing step, a copper pipe is wound on the surface side of a dewatering bucket or / and a standing bucket, and the copper pipe is communicated with the steam generation device to obtain circulating steam to achieve heat preservation. The dewaxing, wax-water separation, dewatering and standing, wax discharging and other procedures can be automatically achieved, the wax recovery treatment efficiency is greatly improved, the recycling treatment effect is good, the recycled wax quality is good, and the quality of a secondarily-machined wax mold is guaranteed.

Description

technical field [0001] The invention relates to a wax recovery and treatment system and method applied to precision casting. Background technique [0002] Casting wax is a precision casting grain, which has the characteristics of hardness, small linear shrinkage, and good writing stability. It can be used after the wax mold is processed to avoid waste of resources. However, it is currently used in the recovery and treatment device of precision casting wax The treatment effect is poor, and the heat preservation of the wax liquid during the transportation process is neglected. It is difficult to add the recycled casting wax or the quality of the processed wax model is low, and the expected effect cannot be achieved. Contents of the invention [0003] In order to overcome the problems existing in the prior art, the present invention proposes a wax recovery treatment system and method applied to precision casting, which is specifically realized by the following technical means...
