[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0033] Example 1

[0034] Reference Figure 1-5 As shown, a preheating device for lithium battery processing includes: a frame 100, a heat preservation chamber 200, a heating component 300, and an air flow disturbance device 400. The heat preservation chamber 200 is fixed on the upper part of the frame 100, and includes a stainless steel liner 210, a track 220 for conveying battery products 99, a heat preservation layer 230, and a storage rack 240 for storing battery products 99.

[0035] The storage rack 240 of the utility model has several storage layers 241, and one or more battery products 99 are placed on each storage layer 241; the storage rack 240 in this embodiment is at least two groups, wherein the number of storage layers 241 is 5-15 layers. The storage rack 240 with a multi-layer structure can meet the cooling operation of more battery products 99. For example, each group of storage racks 240 has 9 layers, and each layer has 9 battery products 99. The device can cool up to 162 (2X9X9) battery products 99 at a time.

[0036] The height of each storage layer 241 of the utility model is not less than 1.5 times the height of the battery product 99, and a limit block 242 is provided on the storage layer 241 to fix the battery product 99. The fixation of the battery product 99 by the limit block 242 ensures the stability of the battery product 99. At the same time, the restriction on the height of the storage layer 241 is conducive to maximizing the efficiency of the battery product 99 during the cooling process.

[0037] In order to prevent the storage rack 240 from moving during operation, a blocking mechanism 221 for fixing the storage rack 240 is provided on the track 220 .

[0038] The heating component 300 of the utility model is placed in the insulation chamber 200 to increase the temperature in the insulation chamber 200. Since the heating temperature during operation is generally 110°C, the heating component 300 is an electric heating resistance wire with a power of 10kw-30kw according to the size of the space.

[0039] In order to improve energy utilization, the insulation layer 230 is an insulation rock wool board with a thickness of 30mm-50mm. The insulation rock wool board has good thermal insulation effect and can effectively prevent heat dissipation. The thickness of the stainless steel liner 210 is 5mm-10mm, which has a good energy-saving and emission reduction effect.

[0040] The air flow disturbance device 400 of the utility model is located at the bottom of the storage rack 240, wherein the number of the air flow disturbance device 400 is at least 2 groups, and each group of the air flow disturbance device 400 includes two fans respectively arranged opposite to each other. Specifically, the air volume of the fan is 40m 3 / min-120m 3 / min. The fan's disturbance improves the drying efficiency of the battery product by 99%.

[0041] Specifically, the use process of this device is as follows:

[0042] ① The front-end equipment transports the storage rack 240 carrying the battery product 99 to the heat preservation chamber 200 via the track 220;

[0043] ②. Fix the storage rack 240, turn on the heating assembly 300, and set the heating temperature and heating time.

[0044] ③. Start the air flow disturbance device 400 and wait for the heating time to end, thus completing the preheating.

[0045] The utility model has the following beneficial effects: (1) the closed structure is adopted to reduce the moisture in the air and avoid the oxidation of the workpiece surface which affects the performance of the product.

[0046] (2) The coordinated use of the track 220 and the storage rack 240 facilitates transportation and saves time.

[0047] (3) The use of the thermal insulation layer 230 and the stainless steel inner liner 210 improves energy utilization, and has a good effect of energy saving and emission reduction.
