Description

Technical Field

[0001] This utility model relates to the field of new energy battery production equipment technology, specifically a tunnel heating furnace for processing new energy batteries. Background Technology

[0002] New energy batteries are energy conversion and storage devices that mainly convert chemical energy or physical energy into electrical energy through chemical reactions. Common types include lithium-ion batteries. During the production and processing of new energy batteries, heating equipment such as heating furnaces are usually used to heat and dry the batteries to ensure that the internal environment of the battery is dry and free of moisture, so as to optimize the performance and safety of the battery.

[0003] In current new energy battery manufacturing processes, heating is typically performed in a drying oven. However, due to the small size of the drying oven, it is insufficient for heating and drying large quantities of batteries. Furthermore, the batteries are usually stationary in the drying oven, leading to uneven heating of the battery surface and affecting the drying efficiency. Additionally, new energy batteries typically require cooling after heating. Traditional air cooling methods involve blowing air directly down on the heated batteries. This method causes the heat dissipated upwards from the batteries to return to the surrounding area, hindering rapid cooling. Moreover, the heat blown away from the batteries dissipates directly into the air, failing to be fully utilized. Utility Model Content

[0004] The purpose of this invention is to provide a tunnel heating furnace for processing new energy batteries, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tunnel heating furnace for processing new energy batteries, comprising a tunnel heating furnace body, a conveyor belt rotatably connected to the middle of the tunnel heating furnace body, multiple vertical rods symmetrically arranged on the outer surface of the conveyor belt, a rotary motor installed on one side wall of the top of each vertical rod, a rotating column provided at the top of each vertical rod, a through cavity opened inside the rotating column, an insert rod provided inside the through cavity, a clamping cavity starting from the middle of the insert rod, multiple partitions fixedly connected to the inner wall of the clamping cavity, an electric heater installed at the top of the inner side of the tunnel heating furnace body, a side frame fixedly connected to one end of the tunnel heating furnace body near the discharge port, a clamping frame fixedly connected to the top of the side frame, a slider provided inside the clamping frame, and a fan installed in the middle of the slider.

[0006] Preferably, one end of the rotating column is fixedly connected to the output end of the rotary motor, and the rotating column is rotatably connected to the vertical rod through the rotary motor.

[0007] Preferably, an inductive switch is installed at one end of the inner side of the cavity, and the inductive switch is electrically connected to the rotary motor.

[0008] Preferably, a linear motor is installed at the bottom of the inner side of the card frame, the slider is slidably connected to the linear motor, and the fan is slidably connected to the card frame through the slider.

[0009] Preferably, a spring sheet is provided on one side wall of the partition.

[0010] Preferably, a limiting strip is fixedly connected to the top of one end of the insertion rod, and a limiting groove is formed on the top of the inner side of the cavity, with the limiting strip and the limiting groove being slidably connected.

[0011] Preferably, the outer wall of the rotating column has a notch, and the notch communicates with the clamping cavity.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This tunnel heating furnace for processing new energy batteries uses vertical rods, rotating columns, insertion rods, and a rotary motor to enable the new energy batteries to rotate along the vertical rods while entering the tunnel furnace for heating and drying via a conveyor belt. This allows the surface of the new energy batteries to receive radiation from the heat source at the top inside the tunnel heating furnace through rotation, ensuring uniform heating of the battery surface and thus facilitating the heating and drying of the new energy batteries.

[0014] 2. This tunnel heating furnace for processing new energy batteries, through side frames, clamping frames, sliders, and fans, allows the fans to blow cold air from the side of the furnace's outlet when the new energy batteries are being cooled by air blowing. This prevents the heat dissipated from the top of the new energy batteries from returning to the surrounding area, thus facilitating faster cooling of the batteries. The heat blown away returns to the tunnel furnace through the outlet. At the same time, when the fan's airflow is strong enough, it can blow the heat dissipated from the batteries towards the feed inlet on the other side of the tunnel furnace to preheat the feed inlet, thereby facilitating the full utilization of heat.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1 to 4As shown, the tunnel heating furnace for new energy battery processing in this embodiment includes a tunnel heating furnace body 1. A conveyor belt 2 is rotatably connected to the middle of the tunnel heating furnace body 1. Multiple vertical rods 3 are symmetrically arranged on the outer surface of the conveyor belt 2. A rotary motor 12 is installed on one side wall of the top of the vertical rod 3. A rotating column 4 is provided at the top of the vertical rod 3. A through cavity 20 is opened inside the rotating column 4. An insert rod 5 is provided inside the through cavity 20. A clamping cavity 16 is formed at the middle of the insert rod 5. Multiple partitions 15 are fixedly connected to the inner wall of the clamping cavity 16. An electric heater 11 is installed at the top of the inner side of the tunnel heating furnace body 1. A side frame 6 is fixedly connected to one end of the tunnel heating furnace body 1 near the discharge port. A clamping frame 7 is fixedly connected to the top of the side frame 6. A slider 9 is provided inside the clamping frame 7. A fan 10 is installed in the middle of the slider 9.

[0024] Specifically, the tunnel heating furnace body 1 is also equipped with electrical components to ensure the normal operation of the tunnel heating furnace, so that the new energy battery can be better heated and dried in the tunnel furnace. The vertical rod 3 supports both ends of the rotating column 4, so that the rotating column 4 can rotate on the conveyor belt 2 under the drive of the rotating motor 12, thereby facilitating the rotation of the new energy battery inside the rotating column 4, so that the outer surface of the new energy battery can be fully heated. The vertical rod 3, rotating motor 12, rotating column 4 and insert rod 5 all have good high temperature resistance properties, so that the above structure can operate normally in the high temperature environment inside the tunnel heating furnace. The function of the clamping cavity 16 is to allow the new energy battery to be directly placed in the insert rod 5, thereby facilitating the installation and removal of the new energy battery. The partition 15 is made of insulating material, so that the new energy batteries placed side by side in the clamping cavity 16 are not likely to interfere with each other. The function of the side frame 6 is to support the fan 10. The function of the slider 9 is to allow the fan 10 to move horizontally left and right along the clamping frame 7, thereby facilitating the adjustment of the blowing position of the fan 10, so that the air blown by the fan 10 can cover a large area.

[0025] Furthermore, one end of the rotating column 4 is fixedly connected to the output end of the rotary motor 12. The rotating column 4 is rotatably connected to the vertical rod 3 through the rotary motor 12. The rotating column 4 can rotate on the vertical rod 3 under the drive of the rotary motor 12, thereby driving the internal insertion rod 5 to rotate.

[0026] Furthermore, an induction switch 13 is installed at one end of the inner side of the cavity 20. The induction switch 13 is electrically connected to the rotary motor 12. The function of the induction switch 13 is that when the plug 5 containing the new energy battery is inserted into the cavity 20, the rotary motor can be controlled to start, thereby facilitating the control of the rotary motor.

[0027] Furthermore, a linear motor 8 is installed at the bottom of the inner side of the frame 7, and the slider 9 is slidably connected to the linear motor 8. The fan 10 is slidably connected to the frame 7 through the slider 9, so that the slider 9 can move horizontally left and right within the frame 7, and the air blown by the fan 10 on the slider 9 can cover a wider range, thereby facilitating the cooling of the new energy battery.

[0028] Furthermore, a spring sheet 14 is provided on one side wall of the partition 15. The function of the spring sheet 14 is to facilitate the new energy battery to fit tightly against the partition 15, thereby making it easier to fix the battery in the cavity 16 and to facilitate the rotation of the battery with the insertion rod 5 and the rotating column 4.

[0029] Furthermore, a limiting strip 17 is fixedly connected to the top of one end of the insertion rod 5, and a limiting groove 19 is opened on the top of the inner side of the cavity 20. The limiting strip 17 and the limiting groove 19 are slidably connected. The function of the limiting strip 17 is to prevent the insertion rod 5 from rotating relative to the rotating post 4 after it is inserted into the rotating post 4, so that the insertion rod 5 can rotate with the rotating post 4, thereby facilitating the rotation of the new energy battery inside the insertion rod 5.

[0030] Furthermore, the outer wall of the rotating column 4 is provided with a notch 18, which communicates with the cavity 16. The function of the notch 18 is to allow the new energy battery fixed in the cavity 16 to be exposed in the tunnel heating furnace, thereby facilitating the heating and drying of the new energy battery.

[0031] The usage method of this embodiment is as follows: When using this tunnel heating furnace for processing new energy batteries, the tunnel furnace needs to be connected to an external power supply first, so that the conveyor belt 2 and the electric heater 11 can start and operate normally. At the same time, the blower 10 can be started, so that the blower 10 blows cold air laterally at the discharge port of the tunnel heating furnace body 1. Then, the new energy batteries to be heated and dried can be clamped into the clamping cavity 16 of the insertion rod 5 by the spring plate 14 on the partition 15. When the insertion rod 5 is full of new energy batteries, the insertion rod 5 can be inserted into the through cavity 20 from the side of the rotating column 4 away from the rotating motor 12 until the end of the insertion rod 5 contacts the induction switch 13 at the inner end of the through cavity 20. The controller starts the rotary motor 12 on the vertical rod 3, causing the rotary motor 12 to drive the rotating column 4 to rotate. At the same time, the limiting strip 17 at the top of the insertion rod 5 will engage with the limiting groove 19 at the top of the inner side of the cavity 20, causing the rotating column 4 to drive the insertion rod 5 and the new energy battery inside the insertion rod 5 to rotate in the tunnel furnace heating furnace body, so that the surface of the new energy battery can be heated evenly. Meanwhile, the fan 10 located at the discharge port of the tunnel furnace can blow cold air to the heated new energy battery, so that the heat emitted by the new energy battery can be blown back into the discharge port, and then flowed in the opposite direction to the inlet of the tunnel furnace to preheat the new energy battery at the inlet.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
