[0037] To solve the problems existing in the prior art that the oven is not suitable for most materials that require stable support, and the materials move back and forth inside and outside the oven, without a stable drying environment and with poor drying effect, the present utility model provides an oven, comprising: a box body 1, the box body 1 includes a chamber; a plurality of gears 3, the plurality of gears 3 are arranged in the chamber and are arranged in multiple layers in the height direction and the length direction of the box body 1, and the gears 3 in adjacent two layers are arranged staggeredly, and the plurality of gears 3 are arranged in two rows side by side in the width direction of the box body 1; two chains 4, the two chains 4 are respectively sleeved on each group of gears 3, and each chain 4 is sequentially engaged with the plurality of gears 3 in each group of gears 3; a plurality of trays 10, the trays 10 are connected between the two chains 4 along the width direction of the box body 1, and the plurality of trays 10 are arranged at intervals along the extending direction of the chain 4, and the trays 10 are used for placing materials to be dried; and a driving device, the driving device is used for driving at least one gear 3 in each group of gears 3 to rotate.

[0038] The arrangement mode of each group of gears 3 and the winding mode of the chain 4 are not limited to only Figure 1 the mode in. The gears 3 can be arbitrarily arranged in multiple layers in the height direction and the length direction of the box body 1, as long as the gears 3 in adjacent two layers are arranged staggeredly. The chain 4 can also be reciprocally sleeved on the gears 3 in the vertical direction, or sleeved on the gears 3 in any direction and any path, as long as the gears 3 and the chain 4 can operate normally. The driving device can be set as a motor, which drives at least one gear 3 in each group of gears 3 to rotate. The driven gear 3 rotates to drive the chain 4 engaged with it to also rotate, thereby driving the remaining gears 3 to rotate. The plurality of trays 10 are also driven by the chain 4 to rotate synchronously due to being connected to the chain 4. The trays 10 place the materials to be dried and provide support for the materials to be dried. Different sizes of materials to be dried can be placed by setting the length of the trays 10, the distance between the two groups of gears 3, and the width of the trays 10, and different numbers of materials to be dried can be placed by setting the number of the trays 10. Since the entire gears 3 and the chain 4 are arranged in the chamber, the materials to be dried are always inside the oven during the drying process, the drying conditions are stable, and the drying effect is good. And the entire oven is provided with multiple layers, and multiple trays 10 can be arranged on each layer, and more materials to be dried can be dried under the same floor area.

[0039] In some embodiments, one of each group of gears 3 is set as a driving gear 5, and the driving device is used for driving the driving gear 5 to rotate. The driving device can be set as one, and a connecting rod is arranged between the two driving gears, and the driving device drives the connecting rod to rotate, thereby simultaneously driving the two driving gears 5 to rotate synchronously; or each driving gear 5 is respectively provided with a driving device, and the two driving devices are set to drive synchronously. The two driving gears 5 rotate synchronously to drive the two chains 4 to rotate synchronously, thereby driving the remaining gears 3 to rotate synchronously, and the trays 10 move smoothly between the two chains 4.

[0040] In some embodiments, each gear 3 is rotatably connected to the inner wall of the box body 1, and the inner wall of the box body 1 provides a supporting force for the gear 3, thereby supporting the entire two sets of gears 3, the chain 4, and the tray 10.

[0041] In some embodiments, as Figure 2 shown, a support rod 7 is connected to one side of the gear 3 close to the inner wall of the box body 1, and the gear 3 is rotatably connected to the inner wall of the box body 1 through the support rod 7. The support rod 7 and the inner wall of the box body 1 can be set to be rotatably connected, and the support rod 7 and the gear 3 can be set to be fixedly connected; or the support rod 7 and the inner wall of the box body 1 can be set to be fixedly connected, and the support rod 7 and the gear 3 can be set to be rotatably connected.

[0042] In some embodiments, as Figure 1 shown, a heat insulation plate 2 extending along the width direction of the box body 1 is arranged in the chamber, and the chamber is divided into a heating area and a heat insulation area along the length direction of the box body 1. At least one gear 3 of the uppermost layer and the lowermost layer of each set of gears 3 is arranged in the heat insulation area. There is a gap between both sides of the heat insulation plate 2 in the height direction and the inner wall of the box body 1 for the chain 4 and the tray 10 to pass through. The inner wall of the heating area is set to have a heating function, and hot air circulation heating or direct heating with a heating pipe can be adopted. The inner wall of the heat insulation area has no heating function, and the heat insulation plate 2 is a heat insulation material to separate the two areas, and the temperature of the heat insulation area is lower than that of the heating area.

[0043] In some embodiments, as Figure 1 shown, the driving gear 5 is arranged in the heat insulation area, and the driving device can also be arranged in the heat insulation area. The lower temperature in the heat insulation area than in the heating area enables the driving device to operate normally without being affected by high temperature. The driving device can also be arranged outside the box body 1. The box body 1 is provided with a loading and unloading port 8 on the wall in the heat insulation area. Since the temperature in the heat insulation area is low, the loading and unloading are not affected by high temperature. Sensors and manipulators can be arranged at the loading and unloading port 8. When the sensors detect that there is no material, the manipulator feeds the material. When the sensors detect that there is material, the manipulator takes away the dried material. Manipulators can also not be arranged, and the loading and unloading are carried out manually. The loading port and the unloading port can be set to be the same or separately arranged. The box body 1 is provided with an air extraction port 9 on the wall in the heating area, and the air extraction port 9 is used to discharge the waste gas generated by heating in the heating area.

[0044] In some embodiments, the driving device drives the driving gear 5 to stop once every time it rotates by the same angle. When the driving gear 5 stops rotating, the loading and unloading port 8 is used for loading or unloading operations. Each time the driving gear 5 rotates, the distance that the chain 4 advances is equal to the distance between adjacent trays 10. In this way, it can be ensured that the stopping position of each tray is the same each time. The loading and unloading port 8 is arranged at the position where the tray 10 stops, which makes the loading and unloading more convenient. It also ensures that the drying time of the material to be dried in each tray 10 is the same, and the product quality obtained is stable.

[0045] In some embodiments, Figure 3 As shown, the housing 1 is also provided with a detector. A number of equally spaced positioning blocks 6 are provided on the wheel disc of the driving gear 5 along its circumference. The distance between each positioning block 6 and the center of the circle of the driving gear 5 is equal. The detector is configured to send a signal to the driving device when it detects that the positioning block 6 rotates to the position of the adjacent positioning block 6, and the driving device stops driving the driving gear 5 to rotate. The driving gear 5 rotates at the same angle when each positioning block 6 rotates to the position of the adjacent positioning block 6. Each time the driving gear 5 rotates, the distance that the chain 4 advances is the distance between adjacent pallets 10. Therefore, the positioning blocks 6 can be set to any number as needed to control the number of pallets 10. The detector can be set on the inner wall of the housing 1 to facilitate the detection of the position change of the positioning block 6. Other forms of devices can also be provided, as long as it is ensured that the driving gear 5 stops once each time it rotates the same angle, and is not limited to the form disclosed in the present invention.

[0046] In some embodiments, Figure 4 As shown, the tray 10 is configured to be U-shaped consisting of two side panels 15 and a bottom panel 16. The side panels 15 are rotatably connected to the chain 4 so that the tray 10 can swing. During the drying process, no matter in which direction the chain 4 and the tray 10 move, the bottom panel 16 is always in a horizontal position, thereby ensuring the drying effect.

[0047] In some embodiments, holes are provided on the side plate 15, and pins are provided through the holes and holes on the segments constituting the chain 4, and the pins are fixed by a retaining spring. I-shaped rivets can also be used to pass through the holes on the side plate 15 and the segments of the chain 4 to rotatably connect the side plate 15 to the chain 4. Any structure that can realize the rotatable connection between the side plate 15 and the chain 4 is acceptable, and is not limited to the present disclosure.

[0048] In some embodiments, the bottom plate 16 is provided with a fixing device 14. During the drying process, heating may cause the bottom plate 16 to deform, resulting in deformation of the material to be dried. Therefore, the fixing device 14 is provided to prevent the bottom plate 16 from deforming. Figure 4 As shown, a square steel pipe is arranged under the bottom plate 16 as the solid device 14. The solid device 14 can also be arranged on the top surface of the bottom plate 16 without affecting the material to be dried, or it can be a solid device 14 of any shape with high temperature resistance and strength.

[0049] In some embodiments, Figure 4 As shown, a limit assembly is provided on the top surface of the bottom plate 16, and the limit assembly is used to form a limit placement area for placing the material to be dried and to limit the position of the material to be dried. During the drying process, the material to be dried is always kept in the limit placement area, and the material to be dried will not be deformed due to the movement of the tray 10. The limit placement area is set to be adjustable in size and can be adjusted according to the size and shape of the material to be dried.

[0050] In some embodiments, the limiting component includes at least two limiting members 12, and the two limiting members 12 are spaced apart along the width direction of the bottom plate 16. As Figure 4 shown, the limiting member 12 is a two-layer stepped block, and the limiting component is composed of eight limiting members 12, with two symmetrically arranged along the width direction of the bottom plate 16 and four symmetrically arranged along the length direction of the bottom plate 16. At least two limiting members 12 along the width direction of the bottom plate 16 form a limiting placement area for placing the materials to be dried, and a total of four limiting placement areas are formed. It can also be as Figure 2 shown. Taking two adjacent groups of the limiting members 12 along the length direction of the bottom plate 16, four limiting members 12 form a limiting placement area, and a total of two limiting placement areas are formed. Therefore, taking two limiting members 12 along the width direction of the bottom plate 16 as a minimum unit group, any number of limiting members 12 can be arranged along the length direction of the bottom plate 16, and taking any group of adjacent limiting members 12 along the length direction of the bottom plate 16 can form limiting placement areas with different lengths for placing materials to be dried of different sizes. In addition, the distance between the limiting members 12 along the width direction of the bottom plate 16 is also adjustable. The screw 13 fixes the limiting member 12 on the bottom plate 16, and the hole on the limiting member 12 for the screw 13 to pass through is formed as a long strip hole extending along the width direction of the bottom plate 16. Moving the limiting member 12 enables the screw 13 to slide in the long strip hole, thereby adjusting the distance between the two limiting members 12 in the width direction of the bottom plate 16 to form limiting placement areas with different widths for placing materials to be dried of different sizes. The limiting members 12 can also be arranged asymmetrically along the length direction and the width direction of the bottom plate 16, or placed obliquely to form an irregularly shaped limiting placement area for placing irregularly shaped materials to be dried.

[0051] In some embodiments, as Figure 2 shown, the material to be dried can be the bipolar plate 11 in the hydrogen energy industry. The bipolar plates 11 are placed in a single layer, and there will be no situation where the drying effect at the top is good while the drying effects in the middle and at the bottom are poor due to the products being stacked together. The drying process of each bipolar plate 11 is the same, ensuring the stability of the product. By adjusting the lengths of the limiting members 12 and the tray 10, various models of bipolar plates 11 can be adapted, and multiple bipolar plates 11 can also be placed on the tray 10 according to the size of the bipolar plates 11. This device can dry multiple bipolar plates 11 at one time, which not only ensures the drying effect but also the production efficiency, and continuous production can also be achieved.

[0052] As Figure 1 shown, below the box body 1 is a supporting device for supporting the entire box body 1. The supporting device can be set as any structure that can support the box body 1, not limited to the present disclosure. The inner wall of the box body 1 is also provided with a heat insulation layer for reducing heat dissipation and more effectively maintaining the temperature inside the box body 1.
