A number of electric heating tubes 30 uniformly and equidistantly arranged horizontally are installed on the top of the drying box 10; an air inlet 11 is opened on the top of the drying box 10, and a dustproof net 12 is installed at the air inlet 11. The surface of the drying box 10 is provided with an insulating shell 13, and a partition 14 is installed in the drying box 10. The partition 14 is arranged below the electric heating tube 30, and a number of blowers 15 uniformly and equidistantly arranged are embedded on the partition 14; the drying box 10 is provided with a closed space for drying the lithium iron phosphate positive electrode material, thereby ensuring the stability and reliability of the drying process; the conveyor belt 20 installed on the drying box 10 can conveniently transport the material to be dried, thereby improving production efficiency. ; By installing a number of evenly spaced and horizontally arranged electric heating tubes 30 on the top of the drying box 10, stable and uniform heat can be provided, ensuring that the material is heated evenly and improving the drying effect; by the air inlet 11 opened at the top of the drying box 10, fresh air is introduced into the drying box 10 to ensure a good drying environment; by installing a dustproof net 12 at the air inlet 11, dust and other impurities are effectively prevented from entering the drying box 10, ensuring the purity of the dried material; by installing a partition 14 in the drying box 10, the electric heating tube 30 is separated from the space below, which plays a certain protective role; by embedding a number of evenly spaced and evenly arranged blowers 15 installed on the partition 14, the air flow can be accelerated, the heat is more evenly distributed in the drying box 10, and the drying efficiency and quality are further improved.
[0027] Furthermore, the insulating outer shell 13 is made of glass fiber reinforced plastic with a thickness of 0.5-1.5 cm. This effectively reduces heat loss during the drying process, improving the thermal insulation performance of the drying box 10. The use of glass fiber reinforced plastic not only ensures the outer shell's durability, but also, due to its excellent thermal insulation properties, further improves drying efficiency and reduces energy consumption, thus achieving energy conservation goals.
[0028] Specifically, the blower 15 adopts a forward and reversible fan, and the forward and reversal of the blower 15 is controlled by a switch. In the initial stage of drying, the forward-rotating blower can quickly and evenly blow hot air to the surface of the material. After long-term use, the blower 15 reverses to blow away the dust on the dustproof net 12.
[0029] It is worth noting that the conveyor belt 20 is provided with a number of mesh holes 23 arranged evenly and equidistantly, and the diameter of the mesh holes 23 is 2-4 mm, which helps to heat the upper and lower surfaces of the material at the same time, reduces the drying time difference, and improves the drying uniformity.
[0030] Among them, conveyor rollers 21 are installed at both ends of the conveyor belt 20, and fixed brackets 22 are installed at both ends of the conveyor rollers 21.

[0033] First, the lithium iron phosphate positive electrode material to be dried is placed on the conveyor belt 20 .
[0034] Start the equipment and the drying box 10 starts working. The drying box 10 provides a closed space for the entire drying process, ensuring the stability and reliability of the drying process.
[0035] At the same time, a number of evenly spaced and horizontally arranged electric heating tubes 30 located at the top of the drying box 10 begin to generate heat, providing stable and uniform heat, ensuring that the material is heated evenly and improving the drying effect.
[0036] During the drying process, fresh air from the outside enters the drying box 10 through the air inlet 11 provided at the top. The dustproof net 12 installed at the air inlet 11 effectively prevents dust and other impurities from entering the drying box 10, thereby ensuring the purity of the dried material.
[0037] The partition 14 installed in the drying box 10 separates the electric heating pipe 30 from the space below, playing a certain protective role.
[0038] A plurality of blowers 15 evenly and equidistantly arranged and embedded on the partition 14 are started to accelerate the air flow, so that the heat is more evenly distributed in the drying box 10, further improving the drying efficiency and quality.
[0039] Finally, the dried material is transported out via the conveyor belt 20, completing the entire drying process.
