Description

Technical Field

[0002] The air flotation oven uses the principle of aerodynamics, commonly known as the wall effect. A series of air flow nozzles are arranged horizontally and staggered up and down inside. The substrate is floated on the hot air to dry. Air flotation drying uses turbulent hot air to act on both sides of the substrate to achieve drying. The effect of wind force on the substrate and the weight of the slurry will form vortex-type wind. When the substrate passes through the nozzle, the hot air supports the substrate forward, so it has a longer contact time, so the drying time is extended and the drying capacity is improved. The advantage of the air flotation dryer is that the guide roller inside the dryer is eliminated. The heating efficiency of the dryer on both sides of the substrate is higher than the heating efficiency on one side, and the purpose of speeding up can be achieved at the same time. Heating and drying both sides of the coated substrate can control the migration of adhesives in the coating and reduce paper curling.

[0026] like Figure 1 - Figure 3 As shown, the utility model provides an air floating air nozzle, comprising a shell 100, a support mechanism 200, an air inlet mechanism 300 and a guide member 400, wherein the shell 100 is provided with a cavity, and the cavity is provided with an air inlet and an air outlet 110; the air inlet mechanism 300 is provided at the air inlet; the guide member 400 is provided at the end of the cavity away from the air inlet, and the air outlet 110 is formed between the guide member 400 and the inner wall of the cavity;

[0027] The support mechanism 200 is bolted to the inner wall of the housing 100 , and the size of the gap of the air outlet 110 is adjusted by adjusting the locking strength of the bolts between the housing 100 and the support mechanism 200 .

[0028] The housing 100 is provided with a cavity, the air inlet mechanism 300 is arranged at the air inlet in the cavity, the air guide 400 is arranged at the end of the cavity away from the air inlet, and an air outlet 110 is formed between the air guide 400 and the inner wall of the housing 100. The airflow direction 10 enters from the air inlet, and after being reflected by the air guide 400, it is discharged from the air outlet 110 formed between the air guide 400 and the inner wall of the housing 100, thereby reducing the risk of uneven airflow caused by the air nozzle blowing directly on the substrate in the prior art. At the same time, since the support mechanism 200 is threadedly connected to the housing By adjusting the locking strength of the bolts of the shell 100 relative to the supporting mechanism 200, and then adjusting the gap size of the air outlet 110, the flow rate and angle of the air nozzle when discharging the gas are realized, and the airflow borne by the substrate is further adjusted, thereby alleviating the hidden danger of uneven wind blowing at the slits of the air nozzle due to the influence of the air nozzle structure processing in the prior art, which leads to the substrate not floating up, or the belt running is unstable, and the up and down shaking is serious, which affects the technical problem of drying efficiency and effect of the electrode, and improves the drying quality of the electrode.

[0029] It should be noted that, in the present embodiment, the shell 100 is manufactured by integrally molding of aluminum material, which not only has sufficient rigidity and flexibility, but also, compared with the sheet metal assembly method used in the prior art, has better manufacturing precision and more stable exhaust airflow, and the wind direction accuracy relative to the substrate is within 0.1 mm. At the same time, the shell 100 can be connected to the support mechanism 200 by a threaded connection. By adjusting the feed strength of the thread, the distance of the shell 100 relative to the guide member 400 is achieved, thereby achieving the adjustment of the size of the air outlet 110.

[0030] Furthermore, the supporting mechanism 200 includes a third pull rod 230 , and the third pull rod 230 is detachably connected between the outer wall of the guide member 400 and the inner wall of the shell 100 .

[0031] The support mechanism 200 includes a third pull rod 230, and the third pull rod 230 can be connected between the outer wall of the guide member 400 and the inner wall of the shell 100 by threaded connection, plug-in, etc. In this embodiment, the guide member 400 is a bowl-shaped structure, and the airflow direction enters the concave surface of the guide member 400 from the air inlet and is discharged along the air outlets 110 on both sides of the guide member 400. The staff can adjust the locking strength of the guide member 400 relative to the third pull rod 230 to achieve the distance between the outer wall of the guide member 400 and the inner wall of the shell 100, that is, adjust the size of the air outlet 110.

[0032] Furthermore, the cross-sectional area of ​​the shell 100 toward the air outlet 110 is greater than the cross-sectional area of ​​the shell 100 toward the air inlet, and the cross-sectional area of ​​the guide cavity in the guide member 400 is greater than the cross-sectional area of ​​the air inlet.

[0033] The shape of the cavity can be set by making the cross-sectional area of ​​the shell 100 toward the air outlet 110 larger than the cross-sectional area of ​​the shell 100 toward the air inlet, so that the airflow can receive the airflow discharged from all the air inlets in the guide member 400 and have enough space for the airflow to be conducted.

[0034] Furthermore, the support mechanism 200 further includes a first pull rod 210 and a second pull rod 220, wherein the first pull rod 210 is disposed at the air inlet, and the second pull rod 220 is disposed between the third pull rod 230 and the first pull rod 210, and the first pull rod 210 and the second pull rod 220 are both used to support the cavity;

[0035] The length of the second rod 220 is greater than that of the first rod 210 .

At the same time, in order to enhance the sealing of the cavity, sealing gaskets 330 are provided around the upper side of the air inlet plate 310 to achieve sealing between the air-floating nozzle and the external oven connection.

[0043] Furthermore, the tuyere end plate 320 covers the side wall of the housing 100, and a seal is provided between the tuyere end plate 320 and the side wall of the housing 100;

[0044] A sealing member is provided between the air guide member 400 and the air nozzle end plate 320 .

[0045] The sealing performance of the device is improved by providing sealing members between the nozzle end plate 320 and the outer wall of the housing 100 and between the air guide member 400 and the nozzle end plate 320 .

[0046] In a second aspect, the present embodiment further provides a drying device, comprising the air-floating air nozzle described above; a plurality of air-floating air nozzles are horizontally staggered and arranged vertically in a drying chamber of the drying device.

[0047] This embodiment achieves the following technical effects:

[0048] 1. The mechanical bolt adjustment ensures the dimensional accuracy of the air outlet 110, uniform air outlet speed, uniform temperature, stable pole suspension and good drying effect;

[0049] 2. By setting the airflow direction to 10, the effect of uneven wind speed of the nozzle is weakened;

[0050] 3. The wall attachment effect is applied at the air outlet 110, which changes the wind direction and makes the wind blow softly on the substrate, reducing the risk of the substrate being blown away;

[0051] 4. By setting the supporting mechanism 200, since the installation method is mechanical installation, its sealing can be guaranteed and the possibility of air leakage can be reduced.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
