Abstract

The invention discloses a wide porous tuyere structure. The wide porous tuyere structure comprises a flow guide cavity, wherein the width of the air discharging end of the flow guide cavity is greater than that of the air intake end of the flow guide cavity, and a wide air discharging plate is arranged at the air discharging end of the flow guide cavity; the wide air discharging plate is provided with a through hole penetrating through the plate face of the wide air discharging plate, the through hole comprises multiple sets of air discharging holes, and the multiple sets of air discharging holes are distributed in the width direction; and the air intake end of the flow guide cavity is communicated with an air uniformizing cavity. According to the wide porous tuyere structure, the air intake end of the flow guide cavity is connected with the air uniformizing cavity, and the air uniformizing plate is arranged in the flow guide cavity, so that the air discharging uniformity of tuyere can be improved, and a battery pole piece can be uniformly dried and blown. Besides, the air discharging plate of the flow guide cavity is designed into the wide air discharging plate, and the multiple groups of air discharging holes are formed in the wide air discharging plate, so that the air discharging area is increased, and the drying quality and efficiency of the battery pole piece can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of oven air nozzles, in particular to a wide-width porous air nozzle structure. Background technique [0002] In the production of battery pole pieces, the coated battery pole pieces need to be dried. As the key equipment for drying battery pole pieces, the oven has the advantages of constant and easy-to-control drying temperature, among which the tuyere structure in the oven has a great influence on the drying quality and coating efficiency of battery pole pieces. [0003] The shape of the air nozzle in the existing oven is generally a slit air outlet structure or a full mesh plate air outlet structure. For example, the air return controllable floating oven air nozzle disclosed in the patent application CN104368509A is a tuyere with a slit air outlet structure. When the shape of the air nozzle is a slit air outlet structure, if the wind speed is too high, the wind speed blowing to the pole piece is also re...
