Vacuum sintering wax steam dewaxing device and dewaxing process

Abstract

A vacuum sintering wax steam dewaxing device and a dewaxing process relate to the technical field of wax steam dewaxing. The device comprise a tank body, a gas inlet pipe is arranged at a gas inlet inthe middle of the tank body, a gas outlet pipe is arranged at a gas outlet in the top of the tank body, the inner side end of the gas inlet pipe extends to an inner cavity of the tank body, a spraying assembly is arranged in the inner side end of the gas inlet pipe, a metal plate is arranged at the position, located below the spraying assembly, of an inner cavity of the tank body, fixing columnsare arranged on the side face of the metal plate, the metal plate is fixed to the inner wall of the tank body through the fixing columns, and a bionic lung is arranged on the upper portion of the inner wall of the tank body. A U-shaped spray pipe, a first spray head, a second spray head, the bionic lung, the spraying assembly, the metal plate and a gear pump which are arranged in the tank body arematched for use, wax and vacuum oil are fully contacted and mixed, so that the dewaxing purpose is achieved, and the vacuum oil can be periodically replaced through the matched use of an oil replacement pipe, the gear pump and other structures, the pipeline does not need to be disassembled for multiple times, the dewaxing rate is increased, and the leakage risk is reduced.

Description

technical field [0001] The invention relates to the technical field of wax steam dewaxing, in particular to a vacuum sintering wax steam dewaxing device and a dewaxing process. Background technique [0002] The current vacuum sintering dewaxing process mostly adopts the principle of low-temperature dewaxing. During the dewaxing process, the existing dewaxing device is relatively easy to cause wax accumulation in the inner cavity of the cooling tube. It is inconvenient and reduces the efficiency of dewaxing, and it needs to be disassembled many times when cleaning the pipeline, which is easy to cause the risk of leakage. Contents of the invention [0003] In order to overcome the deficiencies in the background technology, the object of the present invention is to provide a vacuum sintering wax vapor dewaxing device. The present invention is provided with a U-shaped nozzle, nozzle one and nozzle two, as well as bionic lungs and oil change pipes, etc. in the tank. The struct...
