Problems solved by technology

[0003] However, the above-mentioned prior art coating oven has the following defects: firstly, the upper cavity of the oven cavity is integrally arranged, which cannot completely separate the high-concentration steam from the low-concentration steam, which affects the air volume entering the solvent recovery device; secondly, due to the high Concentrated steam and low-concentrated steam cannot be effectively separated. The gas entering the heating package is a mixture of high-concentrated steam and low-concentrated steam. Flammable and explosive solvents in high-concentrated steam may burn due to mechanical movement, which affects the safety of the coating oven sex

Abstract

The invention discloses a coating oven. The coating oven comprises an oven cavity used for containing drying objects, an upper cavity which is arranged in the oven cavity and located above the drying objects and a lower cavity which is arranged in the oven cavity and located below the drying objects; the upper cavity comprises a blowing cavity and a ventilation cavity, wherein the blowing cavity and the ventilation cavity are independently arranged, the blowing cavity faces the upper surface of the drying objects, and the ventilation cavity can exhaust gas generated by the drying objects out of the oven cavity, and the lower cavity faces the lower surface of the drying objects. According to the coating oven, through the up and down internal circulation of the oven cavity, air flowing and temperature stability of the surface of the drying objects can be improved, through the ventilation cavity, high-concentration solvent steam obtained through evaporation of the upper surface of the drying objects can be rapidly pumped out, the concentration difference of the solvent steam on the upper surface of the drying objects can be increased, and the drying efficiency is improved.

Description

technical field [0001] The invention belongs to the field of coating and drying, more specifically, the invention relates to an efficient and safe coating oven. Background technique [0002] With the rapid development of batteries, especially the rapid development of EV batteries, the requirements for the increase of battery electrode coating production capacity and the safety of coating ovens are getting higher and higher. In order to meet practical needs, the prior art discloses various coating ovens. For example, Chinese invention patent 201220274906.9 filed on June 12, 2012 discloses a coater oven device. [0003] However, the above-mentioned prior art coating oven has the following defects: firstly, the upper cavity of the oven cavity is integrally arranged, which cannot completely separate the high-concentration steam from the low-concentration steam, which affects the air volume entering the solvent recovery device; secondly, due to the high Concentrated steam and l...
