Drying oven capable of discharging air uniformly

Abstract

The invention discloses a drying oven capable of discharging air uniformly. The drying oven comprises an oven body, first air inlet cavities, second air inlet cavities, air blowing nozzles and air outlet cavities, wherein the first air inlet cavities, the second air inlet cavities, the air blowing nozzles and the air outlet cavities are all arranged in the oven body, the first air inlet cavities, the second air inlet cavities and the air blowing nozzles communicate in sequence, the plurality of sets of second air inlet cavities are arranged in parallel, the first air inlet cavities and the air blowing nozzles are arranged on the two opposite sides of the second air inlet cavities correspondingly, included angles between the side walls, away from the second air inlet cavities, of the first air inlet cavities and the second air inlet cavities are acute angles, included angles between the side walls, away from the air blowing nozzles, of the second air inlet cavities and the air blowing nozzles are acute angles, and flow guide valve plates are arranged at the joints where the first air inlet cavities are connected with the second air inlet cavities correspondingly. According to the drying oven, by improving structures of an air inlet channel and the air blowing nozzles, air blown out of the air blowing nozzles is more uniform, and therefore a drying effect of products such as pole pieces is optimized.

Description

technical field [0001] The invention relates to the technical field of ovens, in particular to an oven with uniform air outlet. Background technique [0002] With the advancement of science and technology and the enhancement of environmental awareness, the development of new energy industry is booming. Lithium battery is an important new energy product, which has been widely produced and used. The pole piece is an important part of the lithium battery. The pole piece is obtained by coating the slurry on the substrate and then drying. The drying step directly affects the performance of the pole piece, such as the uniformity and degree of drying of the pole piece. And other properties are all felt by the drying process. The oven is the key equipment for drying battery pole pieces, and plays a vital role in the development of lithium batteries and even new energy. The current oven directly passes the drying air into the air nozzle through a simple pipe, and blows out the dryi...
