Description

Technical Field

[0001] This utility model relates to the field of lithium battery processing technology, specifically to a lithium battery raw material circulating drying device. Background Technology

[0002] A lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. It differs from rechargeable lithium-ion batteries and lithium-ion polymer batteries. The inventor of the lithium battery was Thomas Edison. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental controls. Therefore, lithium batteries were not widely used for a long time. However, with the development of microelectronics technology at the end of the 20th century, the increasing miniaturization of devices placed higher demands on power supplies. This led to the large-scale practical application of lithium batteries.

[0003] Many current raw material drying devices can only dry raw materials from the top or bottom. When drying a large amount of raw materials, it is necessary to have dedicated personnel to continuously turn the materials over and flatten them to ensure that the raw materials are dried evenly. This not only reduces the drying efficiency but also increases the labor costs of enterprises. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a lithium battery raw material circulating drying device to solve the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a lithium battery raw material circulating drying device, wherein a support is fixedly installed on the bottom surface of the drying box, a discharge pipe is fixedly installed on the bottom surface of the drying box, a piston is provided on the inner side of the discharge pipe, a motor is fixedly installed on the bottom surface of the drying box, a rotating shaft is fixedly installed on the top surface of the output shaft of the motor, a drying column is provided on the outer side of the rotating shaft, an extension rod is fixedly installed on the side of the drying column, a top cover is provided on the top surface of the drying column, a fan box is fixedly installed on the top surface of the top cover, and a fan is fixedly installed on the inner side of the fan box.

[0008] Preferably, a handle is fixedly mounted on the bottom surface of the piston.

[0009] Preferably, the drying column has a cavity on its inner side, a rotating shaft sleeve is fixedly installed on the bottom surface of the drying column, the rotating shaft is fitted into the inner side of the rotating shaft sleeve, and an air inlet is provided on the top surface of the drying column.

[0010] Preferably, an air outlet is provided on the side of the extension rod, and an air outlet is provided at the end of the extension rod away from the drying column.

[0011] Preferably, the top surface of the fan box is provided with an air inlet, and the bottom surface of the fan box is provided with a ventilation opening.

[0012] Preferably, the extension rod communicates with the interior of the drying column.

[0013] Compared with the prior art, this utility model provides a lithium battery raw material circulating drying device, which has the following beneficial effects:

[0014] 1. This lithium battery raw material circulating drying device first pours lithium battery raw material granules into the drying chamber, turns on the fan to blow out air, and then starts the motor to start rotating. Since the output shaft of the motor is connected to the rotating shaft, the rotation of the motor can drive the rotation of the rotating shaft. The surface of the rotating shaft is provided with irregular protrusions. Through the irregular pattern on the surface of the rotating shaft and the fitting of the rotating shaft sleeve, the rotating shaft can drive the drying column to rotate. The interior of the drying column is provided with a cavity, so that the air blown by the fan can enter the drying column through the air inlet and enter the extension rod through the cavity. The extension rod is connected to the interior of the drying column. The extension rod can deliver the air to a farther position, ensuring drying efficiency while avoiding the situation of incomplete drying.

[0015] 2. In this lithium battery raw material circulating drying device, the diameter of the side air outlet and the exhaust outlet on the side of the extension rod are smaller than the diameter of the lithium battery raw material. This prevents raw material particles from entering the extension rod during the drying and agitation process. Several side air outlets are set at fixed intervals, allowing the equipment to dry the raw material more evenly and improve drying efficiency. Several extension rods are set in total. When the drying column rotates with the rotating shaft, the extension rods are also driven to rotate, allowing the raw material particles to be turned over and dried evenly. After drying, the piston is pulled out by the handle, and the raw material is collected using a collection device and sent to the next processing step. Attached Figure Description

[0026] Furthermore, a side air outlet 801 is provided on the side of the extension rod 8, and an air outlet 802 is provided at the end of the extension rod 8 away from the drying column 7.

[0028] Furthermore, the top surface of the fan box 10 is provided with an air inlet 1001, and the bottom surface of the fan box 10 is provided with a ventilation opening 1002.

[0029] Through the above technical solution, the air inlet 1001 enables the fan 11 to blow flowing air, while the vent 1002 can send air into the drying column 7.

[0031] Through the above technical solution, air can enter the extension rod 8 from the drying column 7 and flow out through the side air outlet 801 and the outlet 802 to dry the lithium battery raw materials.
