Device for quickly drying ceramic shell

Abstract

The invention discloses a device for quickly drying a ceramic shell and belongs to the technical field of precision casting. The device is designed to solve the problems that in the ceramic shell drying method of the prior art, the quality of a ceramic shell cannot be guaranteed and the ceramic shell cannot be quickly dried at the same time when the ceramic shell has a complex structure. The device comprises a sealing chamber, a heating device, a vacuumizing device and a cooling and condensing device, wherein the sealing chamber is used for holding the ceramic shell to be dried and comprises a chamber body; a sealing door and a gas inlet are formed on the chamber body; the heating device is used for controlling the ceramic shell to be in a constant-temperature state; the vacuumizing device is connected with the sealing chamber body and is used for vacuumizing the sealing chamber body; and the cooling and condensing device is used for cooling part of the gas in the sealing chamber so as to condense wet gas in the sealing chamber.

Description

[0001] This application is a divisional application of an invention patent application with an application date of September 15, 2009, an application number of 200910172987.4, and an invention titled ceramic shell quick drying method and device, and ceramic shell. technical field [0002] The invention relates to precision casting technology, in particular to a quick drying device for pottery shells. Background technique [0003] Compared with the traditional casting process, precision casting is a casting method that can obtain relatively accurate shape and high casting precision. The process of precision casting is as follows: firstly, a wax mold is made, which is consistent with the size and shape of the product to be cast, and then a pottery shell is formed on the surface of the made wax pattern, and then the pottery shell is dewaxed processing (melting the wax pattern inside it and removing it), and finally, pouring metal materials into the dewaxed pottery shell, and af...

Problems solved by technology

This method can also increase the drying speed of the ceramic shell. However, when this method is used, the hygroscopic material adsorbed on the surface of the ceramic shell must be completely removed before the next step of slurry soaking is carried out. Moreover, when the casting structure is complex and has holes, the hygroscopic material is not easy to bury. in, unable to work

[0010] It can be seen from the above that the drying method of the ceramic shell in the prior art cannot not only ensure the quality of the ceramic shell but also realize the rapid drying of the ceramic shell when the structure of the ceramic shell is complex.
