An air guide component of a tuyere, a tuyere component and an oven

Abstract

The invention relates to the technical field of ovens, and discloses an air guide assembly of a tuyere, an air nozzle assembly and an oven. Wherein, the air guide assembly of the tuyere includes: at least one wind-shielding mechanism arranged along the length direction of the tuyere, each of the wind-shielding mechanisms includes a first surface, and two first side surfaces respectively connected to the first surface , the two first sides are opposite to each other; wherein, the first surface is opposite to the tuyere, and one edge of the two first sides away from the first surface is respectively connected to two long sides of the tuyere on the edge. The above-mentioned air nozzle assembly can effectively reduce the amount of hot air in contact with the blank area. Specifically, it can reduce the deformation and wrinkle of the base material (such as the pole sheet foil) in the blank area, and improve the coating layer near the blank area (the surface on the pole piece) Active material layer) edge cracking, etc., thereby effectively improving the yield of coated and dried products (battery pole pieces).

Description

technical field [0001] The invention relates to the technical field of ovens, in particular to an air guide assembly of a tuyere, an air nozzle assembly and an oven. Background technique [0002] In the field of coating, the blank / coating blank area is generally set according to the needs of the product, that is, the coated uncoated area. For the coating of the battery pole piece, it specifically refers to the area on the foil that is not coated with active materials. The area is generally arranged alternately with the coating area to form a zebra pattern; the existing coating oven air nozzle is evenly distributed along the length of the air nozzle, which will cause some problems in the continuous zebra pattern coating, such as close to the remaining The edge of the coating area in the white area is prone to dry cracking, or the middle area of ​​the coating area is wet and the edge area is dry, etc. At the same time, the blank area is also prone to wrinkles, that is, the bas...

AI Technical Summary

Problems solved by technology

[0004] At present, the conventional shielding method is to use Teflon tape to paste the corresponding position of the oven nozzle to achieve shielding. Although this method has a certain effect, the effect is limited, and the tape is easy to fall off or damaged, and needs to be replaced frequently, so it cannot fundamentally Effectively improve the yield of coated products
