Drying oven tuyere of lithium cell pole piece coating machine

Abstract

The invention relates to a drying oven tuyere of a lithium cell pole piece coating machine. The drying oven tuyere comprises a main shell, wherein a lower opening of the main shell is used as an air inlet; inclined planes on the front and rear sides of a top panel of the main shell are provided with a front air outlet and a rear air outlet which are arranged along the length direction of the main shell; the left and right ends of the main shell are connected with a left side plate and a right side plate respectively; an air guide plate is arranged in the main shell; the drying oven tuyere is characterized in that the air guide plate is a wing-shaped air guide plate of which the cross section is wing-shaped; the upper edges of the two wing plates of the wing-shaped air guide plate are connected with the upper edges of the front air outlet and the rear air outlet respectively; the two wing plates of the wing-shaped air guide plate recess and bend towards the top plate. The drying oven tuyere has a simple and ingenious structure and is easy to manufacture, hot air can be uniformly circulated, the pole piece drying effect is good, and the strength and the consistency of the pole piece are improved in the aspect of drying, so that the performance of a lithium power single cell can be greatly improved, and an excellent hot air tuyere is provided for a drying oven of a coating machine of a pole piece of a high-capacity and high-power power type lithium cell.

Description

technical field [0001] The invention relates to an accessory device on a lithium battery pole piece coating machine, in particular to an oven tuyere for a lithium battery pole piece coating machine, belonging to the technical field of new energy equipment. Background technique [0002] With the development of economy and society, rechargeable batteries, especially lithium batteries, are developing at a high speed. Lithium batteries are getting more and more attention due to their high specific energy, long life and environmental protection. Lithium batteries are used in electric vehicles. The application prospect of power supply and energy storage power supply is broad. [0003] Generally speaking, as power batteries are used in combination, the requirements for the consistency of single batteries are very high. Because the conductive framework of lithium batteries is made of very thin copper and aluminum foils, and the coating is very thin, the most important factor affect...

Problems solved by technology

Now the air deflectors usually used in oven nozzles are all V-shaped, and the wind from such air deflectors is directly blown to the pole piece in progress, which makes the pole piece vibrate in different degrees, and the pole piece The uniformity of the air outlet is greatly affected; in addition, due to the wide air outlet, the heat in the hot air will accumulate over time, and the temperature rise will directly affect the strength of the air outlet plate, causing the air outlet to deform, affecting the drying air volume and The uniformity of heat will cause uneven drying of pole pieces

In order to overcome this disadvantage, several horizontal bars are added in the middle of the long air outlet. Although this prevents the deformation of the air outlet, it also blocks the outlet of part of the hot air, so that several different drying bars appear on the pole piece. The degree of traces affects the strength and uniformity of the pole piece after drying
