[0015] Reference Figures 1 to 7 The present invention will be further described below.

[0016] A trolley furnace capable of processing multiple fuel cells includes a support frame 1, a fixed platform 2, and a movable furnace body 3. A top cover plate 4 is flexibly connected to the support frame 1. The fixed platform 2 is located below the top cover plate 4. A fixed side cover plate 5 is provided on one side of the fixed platform 2. The furnace body 3 is located on the other side of the fixed platform 2. An opening corresponding to the side cover plate 5 is provided on the fixed platform 2, and the opening faces the fixed platform 2. The fixed platform 2 is provided with a number of support blocks 6, and the bracket 1 is provided with pressure blocks 7 corresponding to the support blocks 6. A lifting mechanism 40 is provided between the pressure block 7 and the bracket 1, and the pressure block 7 is located below the top cover plate 4. The pressure block 7 is connected to the lifting mechanism 40 through a lifting rod 8, and the lifting rod 8 slides through the top cover plate 4 in a sealed manner. Both the support block 6 and the pressure block 7 are provided with ventilation slots 9 corresponding to the holes on the fuel cell, and the support block 6 is provided with a positioning and mounting block 10. The fixed platform 2 is provided with an exhaust mechanism 29, which includes a first exhaust pipe 12 and a plurality of second exhaust pipes 13 located on the first exhaust pipe 12. A plurality of ventilation tubes 14 are connected to the second exhaust pipes 13. Each ventilation tube 14 is connected to a ventilation slot 9 on the support block 6. The ventilation slot 9 on the pressure block 7 is directly connected to the chamber to discharge the exhaust gas generated by the fuel cell during heating and pressurization. A plurality of exhaust holes are provided on the top cover plate 4 for discharging the exhaust gas in the chamber. The fixed platform 2 is provided with several heating tubes 15, the furnace body 3 is provided with a heating chamber, the furnace body 3 is provided with a circulating fan 16, the heating chamber is provided with several heating rods, the circulating fan 16 absorbs the gas in the chamber and enters the heating chamber, and then blows hot air out from the air outlet on the inner wall of the furnace body 3. The furnace body 3 is provided with an air supply fan 17, and fresh air from the outside is sent into the chamber through the air supply fan 17 and the air supply pipe 18.

[0017] like Figures 1 to 7 As shown, the heating and pressurization process of the fuel cell is as follows: multiple fuel cells are placed sequentially on the positioning mounting block 10 of each support block 6, and positioned by the positioning groove and positioning hole on the positioning mounting block 10. After placement, the furnace body 3 moves toward the side cover plate 5 until it contacts and seals with the side cover plate 5. Then the top cover plate 4 descends to seal the top of the furnace body 3, ultimately forming a sealed cavity. The lifting mechanism 40 on the top cover plate 4 drives the pressure block 7 to press down on the fuel cell, forming vertical pressure with the positioning and mounting block 10. The air supply fan 17 delivers fresh air into the cavity, the heating tube 15 on the fixed platform 2 and the heating rod in the furnace body 3 heat up, and the circulating fan 16 starts, so that the cavity reaches a uniform heating temperature. Special gas is introduced into the fuel cell through multiple ventilation pipes 14 and ventilation slots 9 on the support block 6. An air intake mechanism connected to the ventilation pipes 14 is provided outside the furnace body 3. Then, the exhaust gas in the fuel cell is discharged to the second exhaust pipe 13 through multiple other ventilation pipes 14. The exhaust gas is then concentrated to the first exhaust pipe 12 by the second exhaust pipe 13. Finally, the exhaust gas is discharged to the outside through the external exhaust pipe 11 (exhaust gas collection device). After processing is completed, the gas supply stops, the pressure block 7 rises, the top cover plate 4 rises, and the furnace body 3 is removed. The fuel cell on the positioning and mounting block 10 can then be removed for the next batch of fuel cells to be processed. This allows for the simultaneous processing of more fuel cells, greatly improving production efficiency.

[0018] Specifically, after the furnace body 3 comes into contact with the side cover plate 5, the side of the furnace body 3 is pressed onto the side cover plate 5 by the sealing bolt clamping mechanism on the side cover plate 5.

[0019] like Figure 2 and Figure 3 As shown in the preferred embodiment, the lifting mechanism 40 includes a driving cylinder 19 and a leveling mechanism. The leveling mechanism includes two support plates 20 connected to the bracket 1. One support plate 20 is hinged to an adjusting plate 21. A first driving block 22 and a second driving block 23 are respectively hinged to adjacent sides of the adjusting plate 21. A first adjusting screw 24 is threadedly connected to the first driving block 22. The first adjusting screw 24 is rotatably connected to and hinged to the other support plate 20. A connecting plate 25 is provided on the adjusting plate 21. A cylinder fixing plate 27 is hinged to the connecting plate 25. A second adjusting screw 26 is threadedly connected to the second driving block 23. The second adjusting screw 26 is rotatably connected to and hinged to the cylinder fixing plate 27. The driving cylinder 19 is mounted on the cylinder fixing plate 27. Both the cylinder fixing plate 27 and the adjusting plate 21 are provided with through holes through which the piston rod of the driving cylinder 19 can pass, and the through holes are larger than the piston rod.

[0020] like Figure 2 and Figure 3As shown, specifically, rotating the first adjusting screw 24 causes the adjusting plate 21 to swing up and down in one horizontal direction. The driving cylinder 19 is mounted on the cylinder fixing plate 27, which is connected to the adjusting plate 21 via the connecting plate 25. This allows the cylinder fixing plate 27 and the driving cylinder 19 to swing with the adjusting plate 21, ultimately adjusting the angle of the pressure block 7. Similarly, rotating the second adjusting screw 26 causes the cylinder fixing plate 27 to swing up and down in another horizontal direction. Thus, by swinging the adjusting plate 21 and the cylinder fixing plate 27, the horizontal angle of the pressure block 7 is ultimately adjusted, keeping it in a horizontal downward pressing state. This prevents the pressure block from tilting downward, which could cause the ventilation groove 9 on the pressure block 7 to be misaligned with the fuel cell, and also prevents uneven pressure on the fuel cell.

[0021] like Figure 2 As shown, specifically, both the adjusting plate 21 and the cylinder fixing plate 27 are hinged with connecting blocks 41, and the first adjusting screw 24 and the second adjusting screw 26 are rotatably connected to the connecting blocks 41 on the adjusting plate 21 and the cylinder fixing plate 27, respectively.

[0022] like Figure 2 and Figure 3 As shown in this example, preferably, the cylinder fixing plate 27 is provided with a guide plate 28, the guide plate 28 is slidably connected with a guide rod 29, the guide rod 29 is connected with a drive plate 30, the drive plate 30 is connected to the piston rod of the drive cylinder 19, and the lifting rod 8 is connected to the drive plate 30 to improve the stability and accuracy of the lifting of the pressure block 7.

[0023] like Figure 5 As shown in the preferred embodiment, the bracket 1 is equipped with a lifting motor 31, two input gearboxes 32, and two output gearboxes 33 located on both sides of each input gearbox 32. Each output gearbox 33 is equipped with a connecting rod 34, which is threadedly connected to the top cover plate 4. The lifting motor 31 inputs power to the two input gearboxes 32, and then the input gearboxes 32 transmit power to the two output gearboxes 33 respectively. Finally, the output gearboxes 33 drive the connecting rod 34 to rotate, thereby raising and lowering the top cover plate 4.

[0024] like Figure 5 As shown, specifically, the two input gearboxes 32 are connected by a drive shaft 35. One of the input gearboxes 32 is connected to the main shaft of the lifting motor 31. Each input gearbox 32 is also connected to the output gearbox 33 on both sides by a drive shaft 35. The output gearbox 33 transmits power to the output gearbox 33 through a bevel gear pair. The output gearbox 33 drives the connecting rod 34 to rotate through a worm gear, so that the top cover plate 4 can be raised and lowered through the synchronous rotation of the four connecting rods 34.

[0025] In this example, preferably, the top cover plate 4, the fixed platform 2, the side cover plate 5, and the inner wall of the furnace body 3 are all provided with heat-insulating materials to keep the cavity warm and ensure the stability of the temperature inside the cavity.

[0026] like Figure 6 As shown, in this preferred embodiment, the furnace body 3 is moved by a track 36 installed on the ground and rollers 37 on the furnace body 3, and a drive motor 38 is connected to the rollers 37.

[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
