The following is a description of the embodiments of the present invention based on its overall structure.

[0025] Example 1

[0026] A lithium battery material drying device as shown in the figure includes a mounting table, a conveyor belt, a wind hood, a heat pump, a drying chamber partition, a heat pump mounting frame, a side partition, a heat insulation curtain and a material box;

[0027] A conveyor belt is installed on the top surface of the mounting platform; a heat pump mounting frame is installed above the conveyor belt, and a plurality of heat pumps are installed on the heat pump mounting frame; side baffles are respectively arranged on both sides of the heat pump mounting frame; the upper end of the side baffle is connected to the heat pump mounting frame, and the lower end is connected to the mounting platform; a wind hood is installed on the outer side of the heat pump mounting frame; the heat pump air outlet faces the conveyor belt, and the exhaust port passes through the wind hood and extends to the outer side of the wind hood;

[0028] A drying chamber partition is arranged between the heat pumps installed on the heat pump mounting frame; the upper end of the drying chamber partition is connected to the heat pump mounting frame, and the lower end extends downward; the upper end of the heat insulation curtain is connected to the lower end of the drying chamber partition, and the lower end extends downward; the material box is placed on the conveyor belt to transport materials.

[0029] Next, the working principle of the embodiment is described in detail to enable those skilled in the art to better understand the present invention:

[0030] The conveyor belt runs on the mounting platform and is used to transport the material box. The heat pump is installed on the heat pump mounting frame, and its air outlet faces the conveyor belt. The hot air blown out dries the material on the conveyor belt. The wind hood plays a protective role to prevent the hot air from escaping and foreign matter from entering the conveyor belt. The side partitions and the drying chamber partition play the role of separation and diversion, so that drying chambers with independent spaces are formed on the conveyor belt, so that the hot air acts on the material more concentratedly. The insulation curtain is made of glass fiber insulation cotton and is arranged under the drying chamber partition to droop naturally, which can reduce the heat exchange between the inside and outside of the drying chamber and improve the drying efficiency.

[0031] During operation, the lithium battery materials to be dried are placed in the material box, and the material box is placed on the conveyor belt for transportation. The material box passes through each drying chamber in turn along the conveyor belt for multi-stage drying to achieve the drying effect required for production.

[0032] Example 2

[0033] The difference between this embodiment and embodiment 1 is that the material box includes a material box body, a first filter screen and a support rod; the bottom surface of the top surface of the material box body is open, and the first filter screen is arranged in the middle of the material box body; the bottom surface of the first filter screen is arranged with a support rod. The first filter screen is used to filter the dust and debris generated after the lithium battery material is dried. After the lithium battery material leaves the conveyor belt with the material box, the material box is vibrated to discharge the dust and debris generated after the lithium battery material is dried from the material box, which is convenient and quick to use.

[0034] The working principle of this embodiment is the same as that of Embodiment 1.

[0035] Example 3

[0036] This embodiment differs from the second embodiment in that it further comprises a sealing cloth; the sealing cloth is disposed on the bottom surface of the material box. The sealing cloth is disposed below the first filter screen and can be removed to seal and prevent the lithium battery material or debris from falling onto the conveyor belt during the heating process.

[0037] The working principle of this embodiment is the same as that of Embodiment 1.

[0038] Example 4

[0039] This embodiment is different from the embodiment 3 in that it further includes a weight sensor; the support rod includes a first support rod and a second support rod, and a weight sensor is arranged between the first support rod and the second support rod; the first support rod is arranged below the first filter. The weight sensor is used to measure the weight of the lithium battery material placed in the material box. During the drying process of the material box on the conveyor belt, the weight of the lithium battery material is detected in real time to judge the drying effect, and the temperature of each drying chamber is adjusted accordingly to ensure that the drying effect of the lithium battery material meets the production requirements after the material box leaves the conveyor belt.

[0040] The working principle of this embodiment is the same as that of Embodiment 1.

[0041] Example 5

[0042] This embodiment differs from Embodiment 4 in that it further comprises a circulation pipe and an air vent; the air vent is arranged on the side of the conveyor belt; one end of the circulation pipe is connected to the air vent, and the other end is connected to the heat pump. The air vent is used to extract the hot air in the drying room and transport it back to the heat pump through the circulation pipe, thereby improving the utilization efficiency of heat energy.

[0043] The working principle of this embodiment is the same as that of Embodiment 1.

[0044] Example 6

[0045] The difference between this embodiment and embodiment 5 is that a filter screen is provided at the inlet of the air outlet, and the filter screen has a filtering effect to prevent dust in the drying room from entering the heat pump.

[0046] The working principle of this embodiment is the same as that of Embodiment 1.

[0047] Example 7

[0048] The difference between this embodiment and embodiment 6 is that a partition is provided on the conveyor belt. The partition is used to separate the material boxes on the conveyor belt, thereby ensuring the stability of the material boxes during the transmission process.

[0049] The working principle of this embodiment is the same as that of Embodiment 1.

[0050] In summary, the utility model provides a material box to transport the lithium battery materials to be dried, and transports the material box via a conveyor belt. The material box passes through a drying chamber composed of multiple heat pumps, drying chamber partitions, and side partitions along the conveyor belt to perform multi-stage drying on the lithium battery materials. In this process, the lithium battery materials can undergo multi-stage drying treatment, making the drying process more orderly and controllable. Different drying temperatures can be set in different drying chambers, and the moisture in the lithium battery materials can be gradually and evenly removed, avoiding the situation of incomplete local drying or over-drying that may exist in traditional drying methods, and effectively improving the drying effect and quality. In addition, the utility model is also provided with an exhaust port and a circulation duct, so that the heat energy in the drying chamber is recycled, thereby improving the heat energy utilization rate of the entire drying device.
