[0002] Hard carbon anode materials have been extensively studied in lithium-ion batteries in recent years. Compared to traditional graphite anodes, hard carbon anode materials exhibit superior performance in specific applications (e.g., high capacity and high safety), showing great potential in sodium-ion batteries and some high-performance lithium-ion batteries.

[0003] Carbonization is a key step in the production of hard carbon negative electrode materials. The pre-treated raw materials need to be fed into a high-temperature furnace for carbonization. A common conveying equipment is the pneumatic conveying system: that is, when powdered materials need to be transferred from one location to a high-temperature furnace, a pneumatic conveyor is commonly used. It uses compressed air or vacuum to push the material flow. During the conveying process, traditional pneumatic conveying equipment is prone to accumulation and blockage at the discharge port due to the narrowing of the material port. Regular inspections and even the installation of a knocking device to prevent blockage are often required, which is very inconvenient.

[0030] Working principle: Before using this device, first seal the bottom outlet of the raw material barrel of the material to be transported with the flange pipe 8, and then buckle the sealing buckle cover 3 at the top barrel mouth at the end position; then start the Roots blower 11 for suction, and the high-speed air flow generated enters the large and small head pipes 2 and the conveying pipe 7 through the high-speed air duct 12.

When it moves downward to the bottom end, the protruding hook 33 tip will hook the spring rope 29, and then the reciprocating slide 30 is moved in the opposite direction. After the whole moves upward for a distance, the end of the hook 33 close to the spring rope 29 will be touched by the reset push rod 31, and then it will rotate to quickly loosen the hooked spring rope 29, forming an elastic force and hitting the upper surface of the filter 131 to remove dust.
