Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically to an air nozzle. Background Technology

[0002] Taking a lithium battery coating machine as an example, after the electrode is dried in one oven section, it passes through a density meter. The temperature needs to be kept below 40℃ to ensure accurate measurement by the density meter. At the same time, after the electrode exits the oven, it passes through a set of rollers. If the electrode temperature is too high, the internal stress will be high when passing through the rollers after exiting the oven, which will cause defects such as cracking of the electrode coating, greatly affecting production efficiency and quality. To solve this problem, the existing solutions are to reduce the oven temperature in several oven sections, or to add air knives and water-cooled rollers to the exit of the oven for cooling. The former will affect production efficiency, and the latter will have problems such as poor cooling effect, which cannot solve the problem well. Utility Model Content

[0009] As described above, the air nozzle includes several fins and a cooling pipe that is interwoven with the fins, the cooling pipe being used to contain the cooling medium.

[0010] As described above, in the air nozzle, each of the fins is arranged parallel to each other and is perpendicular to the air inlet.

[0011] As described above, the fins of the nozzle are arranged at equal intervals.

[0025] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0026] Reference Figure 1, Figure 2 A type of air nozzle includes an air nozzle body 1 and a cold air assembly 2; the cold air assembly 2 is disposed inside the air nozzle body 1, and the air nozzle body 1 is provided with an air inlet 11 and an air outlet 12.

[0027] Air enters the nozzle body 1 through the air inlet 11, is cooled by the cold air assembly 2, and is blown out through the air outlet 12, which can cool the electrode sheet more efficiently. Compared with traditional water-cooled rollers, the nozzle can provide a more concentrated and uniform cooling effect, thereby achieving rapid cooling without sacrificing production efficiency.

[0028] In one embodiment, the air inlet 11 and the air outlet 12 are located on opposite sides of the nozzle body 1, which helps to reduce airflow turbulence inside the nozzle, provide more stable cooling air, reduce adverse effects on the electrode, and stabilize the air volume.

[0029] In one embodiment, the cooling air assembly 2 includes a plurality of fins 21 and cooling pipes 22 that are interposed and connected to the fins 21. The cooling pipes 22 are used to contain the cooling medium. The fins 21 can increase the heat exchange area, and the interposed connection of the cooling pipes 22 to the fins 21 can increase the heat dissipation efficiency of the fins 21, thereby improving the cooling efficiency.

[0030] As an example, the cooling medium is an aqueous solution of water and ethylene glycol.

[0031] As an example, the cooling pipe 22 may be one or several. If the cooling pipe 22 is one, then the cold-cutting pipe 22 is arranged to pass through all the fins 21; if the cooling pipe 22 is several, then the fins 21 of the cold-cutting pipe 22 are arranged to pass through one of the cold-cutting pipes 22.

[0032] Furthermore, each of the fins 21 is arranged in parallel to each other and is perpendicular to the air inlet 11; this can reduce the wind resistance at the air inlet 11, reduce the resistance to air flow, balance the air pressure at the air outlet 12, and prevent excessive local pressure at the air outlet 12 from damaging the substrate.

[0033] Specifically, the fins 21 are arranged at equal intervals, which helps to balance the temperature uniformity at each point of the air outlet 12.

[0034] In one embodiment, the air outlet 12 is two symmetrical strip-shaped air outlets, and a return air cavity 13 is provided between the two strip-shaped air outlets. A return air plate 14 is covered on the return air cavity 13, and a return air hole 141 is provided on the return air plate 14 located between the two strip-shaped air outlets.

[0035] Specifically, there are multiple return air holes 141, which are arranged along the length of the strip-shaped air outlet;

[0036] Specifically, the two strip-shaped air outlets are symmetrically arranged with the arrangement axis of the return air holes 141 as the axis.

[0037] The air blown out from the air outlet 12 becomes return air after encountering the substrate. The return air enters the return air chamber 13 through the return air hole 141 in the middle of the upper surface of the air nozzle. The air in the return air chamber 13 is then blown out through the air outlet 12, without interfering with the air blowing from the air outlet 12, thereby reducing the fluctuations that may be caused by the substrate.

[0038] Furthermore, the two air outlets 12 are inclined towards each other. This facilitates guiding the air blown out of the air outlets 12 into the return air hole 141.

[0039] In one embodiment, pressure relief ports 15 are provided at both ends of the nozzle body 1 and on both sides of the air outlet 12. In actual application, since the air blown towards the electrode has a certain pressure, under this pressure, the cold air between the nozzle body 1 and the electrode will enter the interior of the return air cavity 13 through the return air hole 141, and then be discharged to the outside through the two pressure relief ports 15. This can play a pressure relief role and avoid excessive air pressure from damaging the electrode structure.

[0040] Furthermore, the pressure relief port 15 is located between the cooling air assembly 2 and the air outlet 12. This reduces airflow turbulence inside the nozzle body 1, prevents the pressure relief airflow from affecting the air intake at the air inlet 11, and provides more stable cooling air.

[0041] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
