Technical Field

[0001] The utility model relates to the technical field of battery processing equipment, in particular to a furnace structure of a multi-layer tunnel drying machine. Background Art

[0002] Tunnel dryers are commonly used equipment for drying battery cells. Tunnel dryers include a furnace and a conveying device that passes through the furnace. The conveying device conveys the battery cells into the furnace for heating. In order to reduce the floor space of the dryer, the tunnel dryer can adopt a multi-layer structure in the vertical direction. In this case, multiple conveying devices are also arranged in the vertical direction. For this type of multi-layer tunnel dryer, the furnace structure also needs to be changed accordingly, especially in terms of the strength of the furnace structure. Since the weight of the conveying device can reach more than 100 kilograms, how the furnace structure can provide stable support for the conveying device has become a technical problem to be solved.

[0013] The cross beam, longitudinal beam and frame all include upper end surfaces at the same height, and the partition is placed on the upper end surfaces, so that the upper ends of the cross beam, longitudinal beam and frame can abut against the partition, increasing the contact area between the entire support assembly and the partition.

[0014] Furthermore, the cross beam has a first slot downwardly formed from its upper end surface, and the longitudinal beam has a second slot upwardly formed from its lower end surface, and the first slot and the second slot can be plugged into each other.

[0039] In this embodiment, a partition 2 is used as an example. At this time, the partition 2 divides the drying chamber into two process chambers 3, and a conveying device (not shown in the figure) passes through each process chamber 3. Because the conveying device is fixed on the partition 2 in the upper process chamber 3, the partition 2 will be subjected to a large downward force. Therefore, the stability of the partition 2 is particularly important.

[0040] In one embodiment, the furnace structure further includes a support assembly 4 and a reinforcement assembly 5 . The support assembly 4 is fixed under the partition 2 and is used to support the partition 2 . The support assembly 4 is a grid structure and is fixedly connected to the main shell 1 .

[0041] At least one reinforcing component 5 is correspondingly arranged for the supporting component 4 . Each reinforcing component 5 is located below the corresponding supporting component 4 and provides an upward supporting force for the supporting component 4 .

[0042] In this embodiment, the support assembly 4 of the grid structure provides stable support for the partition 2, which can effectively transfer the load, form a stable force transmission structure, and transmit the force to the main shell 1. At the same time, the grid structure can avoid local deformation of the partition 2. The reinforcement assembly 5 provides an upward support force for the partition 2 to improve the strength of the partition 2.

[0043] In this embodiment, the reinforcing assembly 5 is disposed between the bottom plate 12 and the supporting assembly 4 . However, when there are two or more partitions 2 , a reinforcing assembly 5 is further disposed between two adjacent partitions 2 .

[0044] See attached Figure 4As shown, the support assembly 4 includes a frame 41, a crossbeam 42 and a longitudinal beam 43.

[0045] In one embodiment, the cross beam 42, longitudinal beam 43 and frame 41 all include upper end surfaces at the same height, and the partition 2 is placed on the upper end surfaces. In this way, the upper ends of the cross beam 42, longitudinal beam 43 and frame 41 can abut against the partition 2, increasing the contact area between the entire support assembly 4 and the partition 2.

[0046] In one embodiment, a plurality of support rods 44 are fixed to the frame 41 . The support rods 44 extend in the up-down direction, and the lower ends of the support rods 44 abut against the bottom plate 12 . At this time, the support rods 44 provide a supporting force for the frame 41 .

[0047] In one embodiment, the cross beam 42 and the longitudinal beam 43 are both rod-shaped structures with square cross sections, and each cross beam 42 or longitudinal beam 43 can be an integral structure. Of course, the cross beam 42 or longitudinal beam 43 can also be formed by splicing multiple rod-shaped structures through connecting plates, and the splicing plates fix two adjacent rod-shaped structures.

[0048] In one embodiment, the cross beam 42 has a first slot 421 formed downward from its upper end surface, and the longitudinal beam 43 has a second slot 431 formed upward from its lower end surface, and the first slot 421 and the second slot 431 can be plugged into each other.

[0054] In one embodiment, the cross bar 51 may be an integral structure or may be formed by splicing a plurality of rods.

[0055] In one embodiment, see the attached Figure 4 As shown, the connecting members 53 are arranged at intervals along the front-to-back direction, and each of the connecting members 53 includes at least one fixing plate 531, and the fixing plate 531 is fixed on the supporting assembly 4.

[0056] In one embodiment, one reinforcing assembly 5 is provided, and the reinforcing assembly 5 is located on the center line along the left-right direction. Because the edge of the supporting assembly is fixed on the main shell, it has a certain supporting force, but there is no support on this center line, and downward deformation is easy to occur here. Therefore, the reinforcing assembly 5 is arranged on this center line, which can support the supporting assembly 4 in the vertical direction to the maximum extent.

[0060] In one embodiment, the partition plate 2 is provided with a through hole 21 on one side close to the outlet 132 for connecting with the adjacent process chamber 3.
