Continuous coating furnace

Abstract

The invention discloses a continuous coating furnace. The continuous coating furnace comprises a feeding structure, a thermal decomposition mechanism, a cooling and discharging mechanism, a water vapor heating mechanism and an electric cabinet; the thermal decomposition mechanism is provided with a dehydration cavity, a turnover cavity and a decomposition cavity; the feeding mechanism feeds an impregnated tantalum capacitor into the thermal decomposition mechanism; dehydration is performed through the dehydration cavity; reaction state transition is performed through the turnover cavity; the decomposition cavity performs oxidation reaction, water vapor is provided through the water vapor heating mechanism in the reaction process, and cooling and discharging are performed through the cooling and discharging mechanism after reaction. According to the continuous coating furnace, the structure in a thermal decomposition cavity is optimized, so that the internal temperature is uniform, theair speed is uniform and controllable, the oxygen content is accurately adjustable and controllable, and the coating effect is improved.

Description

technical field [0001] The invention relates to the field of coating furnaces, in particular to a continuous coating furnace. Background technique [0002] Coating furnace is a kind of equipment for coating tantalum capacitors. Coating is the process of putting tantalum capacitors impregnated with manganese nitrate solution into the furnace for multiple thermal decomposition to form a layer of manganese dioxide film. Early domestic coating furnaces are all It was imported from abroad, trying to develop domestic industrial technology, and some film furnace manufacturers have appeared in China, but the domestic self-produced film furnaces have the following problems: 1) The temperature uniformity is large, and the internal temperature Unevenness; 2), the uniformity of the internal wind speed is difficult to control; 3), the concentration of oxygen content during thermal decomposition cannot be adjusted and controlled accurately, these problems make the performance of domestic ...
