Technical Field

[0001] This application relates to the field of ovens, and in particular, to a partitioned film oven. Background Art

[0002] Currently, for the processing of industrial films such as electrolyte diaphragms and polymer films, steps such as material preparation, mixing and melting, cooling and pulverization, hot pressing, composite treatment, cleaning, and drying are usually carried out in sequence. In the drying step, in order to improve processing efficiency and ensure processing quality, an oven is usually selected, and the drying temperature is manually controlled to achieve the drying treatment of the film.

[0003] Common ovens generally use hot air drying, that is, hot air is introduced into the oven. This drying method has a fast drying speed, stable temperature and easy adjustment, which helps to ensure the processing quality of the film.

[0004] However, when traditional ovens are used, the following technical problems will exist: due to the large space inside the oven, the temperature of each area inside the oven is inconsistent, and there is poor air circulation or slow air circulation speed in local dead corners inside the oven, resulting in poor heating uniformity. For current production and processing requirements, this problem needs to be improved. Summary of the Utility Model

[0015] Preferably, the driving device includes a driving roller and a driven roller, and the driving roller and the driven roller are respectively located at the upper and lower parts of the box body.

[0016] By adopting the above technical solution, the combined use of the driving roller and the driven roller can stably convey the film, ensuring that the film remains flat during the drying process and avoiding affecting the drying effect due to film wrinkles.

[0017] Preferably, a plurality of driving rollers and driven rollers are provided, and the driving rollers and the driven rollers are alternately arranged in the transverse direction.

[0018] By adopting the above technical solution, the alternate arrangement of a plurality of driving rollers and driven rollers can further increase the stability of film conveyance, ensuring that the film always remains flat during the drying process.

[0019] Preferably, an oven door is provided on the side wall of the box body, and an openable and closable top heat insulation cover is provided on the top of the box body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] The following is a further detailed description of the present application in conjunction with the attached Figures 1 - 3 to the present application.

[0035] This embodiment discloses a partitioned film oven. Refer to Figure 1 and Figure 2, including components such as a box body 1, a partition baffle 2, a driving device 3, a hot air duct 4, and a return air duct 5. A film inlet 12 and a film outlet 13 are provided on the side wall of the box body 1 for the entry and exit of the film. The partition baffle 2 is vertically arranged inside the box body 1, dividing the interior of the box body 1 into multiple independent drying bins 11, and through holes for the film to pass through are provided on the partition baffle 2, enabling the film to pass through each drying bin 11 in sequence.

[0036] Referring to Figure 1 and Figure 3 , a driving device 3 is arranged in each drying bin 11, including a driving roller and a driven roller 32. The driving roller is driven by a motor 14 fixed on the outer wall of the box body 1, thereby driving the film to pass through multiple drying bins 11 in sequence. The hot air duct 4 is arranged in the drying bin 11 for introducing hot air, and the return air duct 5 is arranged opposite to the hot air duct 4 for discharging the hot air in the drying bin 11.

[0037] During the operation of the partition type film oven, the film enters the oven from the film inlet 12 and passes through multiple drying bins 11 in sequence under the action of the driving device 3. Hot air is introduced into each drying bin 11 to heat and dry the film. The hot air enters the drying bin 11 through the hot air duct 4 and is discharged through the return air duct 5 to form a circulating flow. Through the design of multiple independent drying bins 11 and the circulating flow of hot air, the uniformity of film heating and drying is improved.

[0038] Furthermore, in order to improve the stability of film movement, in the embodiment of the present application, the driving roller and the driven roller 32 are respectively arranged at the top and bottom of the drying bin 11. Specifically, the driving roller is located at the top of the drying bin 11 and is at the same horizontal height as the through hole on the partition baffle 2, while the driven roller 32 is located at the bottom of the drying bin 11. Further still, multiple driving rollers and multiple driven rollers 32 are provided, and the multiple driving rollers and the multiple driven rollers 32 are alternately arranged in the horizontal direction. One side of the film bypasses the driven roller 32 and the driving roller and is in an S shape, effectively increasing the length of the film in the drying bin 11, thereby ensuring sufficient drying.

[0039] Referring to Figure 1 and Figure 3 , further, in order to ensure the stable supply of hot air, a heating device 6 is additionally provided in this embodiment. The heating device 6 is arranged outside the box body 1 and is connected to the hot air duct 4 and the return air duct 5 to provide a stable hot air source.

[0040] Specifically, the heating device 6 includes a plurality of heat exchangers 61. The plurality of heat exchangers 61 can operate independently. The air supply duct 4 and the return air duct 5 form a ventilation assembly. At the same time, in order to realize the introduction of hot air into each drying bin 11, multiple groups of ventilation assemblies need to be provided and are correspondingly connected to the plurality of heat exchangers 61 one by one. And the multiple ventilation assemblies are also correspondingly connected and communicated with the plurality of drying bins 11 one by one, so as to realize the independent control of the temperature in each drying bin 11.

[0041] Referring to Figure 2 and Figure 3 , a temperature sensor 7 is provided in each drying bin 11 for real-time monitoring of the temperature in the drying bin 11.

[0042] Therefore, through the cooperation of the plurality of heat exchangers 61 and the ventilation assemblies, the temperature of each drying bin 11 can be independently controlled. The temperature sensor 7 real-time monitors the temperature in each drying bin 11, and the staff can adjust the working state of the corresponding heat exchanger 61 according to the temperature data, so as to accurately control the temperature of each drying bin 11 and ensure that the film can obtain a uniform heating effect in each drying bin 11.

[0043] Regulating valves are provided on both the air supply duct 4 and the return air duct 5 for regulating the hot air flow rate. At the same time, a heat insulation layer is provided on the outer wall of the box body 1 to reduce the heat dissipation to the outside.

[0044] For the convenience of operation and maintenance of the film oven, an oven door 15 is provided on the side wall of the box body 1, and a perspective window is provided on the oven door 15. In addition, a heat-insulating cover 16 that can be opened and closed is provided on the top of the oven, and the internal structure of the oven can be repaired and maintained by opening the heat-insulating cover 16.

[0045] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
