Novel hot air circulation baking oven

Abstract

The invention discloses and provides a novel hot air circulation baking oven. The baking oven comprises a combustion chamber, a combustion catalyst chamber, a circulating fan, a heat exchanger and a steam energy saver, wherein an airflow circulation channel, a baking channel and a solvent steam channel are arranged in the combustion chamber, the baking channel is divided into an evaporation area and a solidification area, the combustion catalyst chamber is arranged between the airflow circulation channel and the solvent steam channel, the circulating fan is arranged on an inlet side close to the airflow circulation channel, the inlet of the airflow circulation channel is communicated with the heat exchanger which is communicated with the energy saver, the energy saver is provided with a fresh air input pipe and a waste air exhaust pipe, a heat recovery airflow channel is further arranged in the combustion chamber, a heat recovery airflow opening is arranged in the heat exchanger and is communicated with the heat recovery airflow channel, the heat recovery airflow channel is divided into a first sub-channel, a second sub-channel and a third sub-channel, the first sub-channel is led to the solidification area, the second sub-channel is led to the evaporation area, the third sub-channel is led to the solvent steam channel, and the heat recovery airflow channel is close to a pipe opening of the barking channel and tilts to an inlet of the evaporation area. The novel hot air circulation baking oven is mainly applied to the field of varnished wires.

Description

technical field [0001] The invention relates to a novel hot air circulation oven. Background technique [0002] In the production of enameled wire, the baking of enameled wire is an essential link. During the enameled wire painting and baking process, the polycondensation and curing of the paint and the evaporation of the solvent are carried out in the oven. The curing of the paint into a film requires a lot of heat, which consumes a lot of electricity. When the existing enameled wire is baked, the solvent in the insulating varnish evaporates and the gas burned in the catalytic chamber is directly discharged into the air, and the discharged gas takes away a large amount of heat, resulting in a waste of energy. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a new hot air circulation oven with high baking efficiency, sufficient solvent vapor combustion and energy sav...
