[0021] The present invention will be further described in detail below with reference to embodiments: Example 1: As Figure 1-5As shown, this utility model provides a circulating drying device for processing lithium battery raw materials, including a drying chamber 1; and a PLC controller 2 disposed on the outer surface of the drying chamber 1 for control. A thermometer is disposed inside the drying chamber 1, and a conveying unit 3 and a drying unit 4 are disposed on the outer surface of the drying chamber 1. The conveying unit 3 includes a conveying assembly disposed on the outer surface of the drying chamber 1 and a material-turning assembly disposed inside the drying chamber 1. The drying unit 4 includes a heating assembly disposed on the outer surface of the drying chamber 1 and a circulating assembly disposed on the outer surface of the drying chamber 1. The conveying assembly includes a first conveyor belt 31, the outer surface of which is rotatably connected to the inner wall of the drying chamber 1. A second conveyor belt 32 is rotatably connected to the inner wall of the drying chamber 1. The material-turning assembly includes a guide plate 33 fixedly connected to the inner wall of the drying chamber 1. A mounting frame 34 is fixedly connected to the outer surface of the guide plate 33. A hydraulic cylinder 35 is detachably connected to the outer surface of the mounting frame 34. The telescopic end of 35 is detachably connected to a tilting plate. The outer surface of the tilting plate is fixedly connected to a limiting rod 36 that slides on the inner wall of the mounting frame 34. The outer surface of the guide plate 33 is fixedly connected to a spring column 39. The other end of the spring column 39 is fixedly connected to a baffle 38. The outer surface of the baffle 38 is fixedly connected to a pressure sensor 37 that is detachably connected to the outer surface of the guide plate 33. When using the circulating drying device for lithium battery raw material processing, the raw material to be dried is first placed on the outer surface of the first conveyor belt 31 for conveying. Then, the drying unit 4 inside the drying box 1 is used to assist in drying the raw material. During the drying process, when the raw material passes one side of the first conveyor belt 31, it falls onto the outer surface of the baffle 38. When the pressure of the spring column 39 changes, the PLC controller 2 can trigger the hydraulic cylinder 35 to move in conjunction with the limiting rod 36 to drive the tilting plate to move, thereby pushing the raw material to flip over, so that the raw material can enter the outer surface of the second conveyor belt 32 for continued conveying.

[0022] Example 2: Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the heating assembly includes a heating box 41, the outer surface of which is fixedly connected to the top of the drying box 1, an air pump 42 is detachably connected to the upper surface of the heating box 41, the output end of the air pump 42 extends into the interior of the heating box 41, a heating resistance wire is provided inside the heating box 41, a connecting pipe 43 is fixedly connected to the outer surface of the heating box 41, the other end of the connecting pipe 43 is fixedly connected to a gas distribution box 47 fixedly connected to the inner wall of the drying box 1, and an air jet pipe 48 is provided on the outer surface of the gas distribution box 47. The circulation assembly includes a drying box 44, the interior of which is connected to the interior of the drying box 1, an activated carbon plate 46 is detachably connected to the inner wall of the drying box 44, and a circulation pump 45 is detachably connected to the upper surface of the drying box 44, the output end of which is connected to the air distribution box 44 via a gas jet pipe 48. The pipe is connected to the interior of the air distribution box 47. When the raw materials need to be dried, the PLC controller 2 can be used to control the start of the air pump 42 to spray air into the interior of the heating box 41. The heating resistance wire in the heating box 41 is used to assist in heating the cold air into hot air, which is then transported to the air distribution box 47 through the connecting pipe 43 and sprayed out from the air jet pipe 48, thereby assisting in the drying of the raw materials. During the drying process, the temperature inside the drying box 1 is monitored by a thermometer. When the set temperature is reached, the air pump 42 is turned off, and then the circulation pump 45 is started to work with the drying box 44 and the activated carbon plate 46 to dry the hot air inside the drying box 1 and then transport it back to the air distribution box 47, thereby circulating the hot air and saving energy. When the temperature inside the drying box 1 drops to the set temperature due to energy loss, the air pump 42 is started again for auxiliary heating to achieve circulating heating.

[0023] The working principle of this circulating drying device for lithium battery raw material processing will be explained in detail below.

[0024] like Figure 1-5As shown, when using the circulating drying device for lithium battery raw material processing, the raw materials to be dried are first placed on the outer surface of conveyor belt 31 for conveying. Then, the drying unit 4 inside the drying chamber 1 assists in drying the raw materials. During the drying process, when the raw materials pass one side of conveyor belt 31, they fall onto the outer surface of baffle 38. When the pressure of spring column 39 changes, the PLC controller 2 can trigger the hydraulic cylinder 35 to move in conjunction with the limit rod 36, thereby pushing the raw materials to flip and allowing them to enter the outer surface of conveyor belt 32 for continued conveying. When the raw materials need to be dried, the PLC controller 2 can control the start of air pump 42 to pump air into the heating chamber 41. The air is injected and heated by the heating resistance wire in the heating box 41, turning the cold air into hot air. The hot air is then transported to the air distribution box 47 via the connecting pipe 43 and ejected from the air injection pipe 48, thus assisting in the drying of the raw materials. During the drying process, the temperature inside the drying box 1 is monitored by a thermometer. When the set temperature is reached, the air pump 42 is turned off, and then the circulation pump 45 is started to work with the drying box 44 and the activated carbon plate 46 to dry the hot air inside the drying box 1 and then transport it back to the air distribution box 47, thus circulating the hot air and saving energy. When the temperature inside the drying box 1 drops to the set temperature due to energy loss, the air pump 42 is started again for auxiliary heating to achieve circulating heating.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
