Tantalum capacitor vacuum sintering dewaxing furnace

Abstract

The invention discloses a tantalum capacitor vacuum sintering dewaxing furnace. The tantalum capacitor vacuum sintering dewaxing furnace mainly comprises a furnace body, a furnace cover, a furnace pipe and a degreasing trapping system, and is characterized in that the furnace cover is connected with the furnace body through a furnace cover lifting mechanism and arranged right above the furnace body; the furnace pipe is arranged in the furnace body; a heater and a workpiece lifting basket are arranged in the furnace pipe; the degreasing trapping system is connected with the furnace body through a pipeline; a muffle tank is arranged in the furnace pipe; the workpiece lifting basket is positioned in the muffle tank; an air suction hole is formed in the bottom of the muffle tank and connected with the pipeline; and an air filling hole is formed in the side wall at the upper part of the furnace body and filled with inert gas. According to the tantalum capacitor vacuum sintering dewaxing furnace, the gas filled in the furnace and the gas generated by dewaxing are sucked away along the bottom of the muffle tank when the temperature in the furnace is increased in the dewaxing process, so that a bonder generated under a high temperature is not volatilized onto a heating chamber in the furnace or a furnace wall, the pollution is prevented being formed, the cleaning frequency of the dewaxing furnace is reduced, and the product quality is effectively improved.

Description

technical field [0001] The invention relates to a tantalum capacitor vacuum sintering dewaxing furnace, in particular to a tantalum capacitor vacuum sintering dewaxing furnace which is easy to obtain high-quality products, has high efficiency and low cleaning frequency. Background technique [0002] The current tantalum capacitor sintering and dewaxing furnace adopts the internal heating type. During the heating and dewaxing process of the product, the inside of the furnace body is in a high temperature state. The wall is cooled by water, so a large amount of binder will volatilize to the furnace wall, and the sticky binder will form a cold well effect and no longer volatilize, seriously polluting the heating chamber, making the second furnace product dewaxing during sintering The phenomenon that the workpiece is contaminated, so that the quality of the product is difficult to control. In addition, in order to ensure the quality of the product as much as possible, the curre...

[0002] The current tantalum capacitor sintering and dewaxing furnace adopts the internal heating type. During the heating and dewaxing process of the product, the inside of the furnace body is in a high temperature state. The wall is cooled by water, so a large amount of binder will volatilize to the furnace wall, and the sticky binder will form a cold well effect and no longer volatilize, seriously polluting the heating chamber, so that there is a risk of dewaxing when the second furnace product is sintered. The phenomenon that the workpiece is contaminated, so that the quality of the product is difficult to control

In addition, in order to ensure the quality of the product as much as possible, the current dewaxing furnace often needs to be cleaned after burning several furnaces, but there are cumbersome disassembly and assembly and labor-intensive situations.
