DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See Figures 1 to 4A lignin dispersing device includes a tank body 100. The top of the tank body 100 is provided with a first opening 110 for feeding, and the bottom of the tank body 100 is provided with a second opening 120 for discharging. A first baffle 111 is provided at the first opening 110. The first baffle 111 has an annular structure and is inclined toward the center of the tank body 100, thereby guiding the lignin poured into the first opening 110 and concentrating the lignin as it enters the first opening 110.

[0022] A spirally arranged air supply duct 200 is installed on the inner wall of the tank body 100. The air supply duct 200 extends to the outside of the tank body 100 and is connected to an external fan. The external fan supplies air into the air supply duct 200. At the same time, a plurality of air outlets 210 are set in the air supply duct 200. The air outlets 210 face the center of the tank body 100. The air in the air supply duct 200 is blown toward the center of the tank body 100 through the air outlets 210, thereby dissipating the heat of the lignin during the falling process to improve the heat dissipation efficiency. The air outlet 210 is connected to the air outlet nozzle 220.

[0023] The air outlet nozzle 220 includes a main body and an air outlet passage 221 extending through the main body. The air outlet passage 221 comprises a first section 222 adjacent to the air supply duct 200 and a second section 223 connected to the first section 222. The diameter of the first section 222 gradually decreases from the end connected to the air supply duct 200 toward the end connected to the second section 223. The diameter of the second section 223 gradually increases from the end connected to the first section 222 toward the other end. The airflow flowing through the first and second sections 222, 223, diffuses outward due to the Venturi effect, thereby improving heat exchange efficiency and ensuring heat dissipation performance.

[0024] A guide member 400 is provided inside the tank body 100 and is located below the second opening 120. The guide member 400 is a tapered structure with its tip facing the first opening 110. A plurality of radially distributed guide plates 410 are provided on the surface of the guide member 400. Adjacent guide plates 410 form a waiting area 420. Lignin falling from the first opening 110 falls into the waiting area 420. As the guide member 400 rotates, the lignin is thrown out of the waiting area 420 and then scattered into the tank body 100, thereby increasing the contact area between the lignin and the air and ensuring heat dissipation efficiency.

[0025] A bracket 300 is mounted on the top of the first opening 110. The bracket 300 includes legs that are mounted on the top of the tank body 100. A support platform 320 is fixed to the top of the legs. A motor 321 is mounted on the support platform 320. The output shaft of the motor 321 is connected to a connecting rod 322. The connecting rod 322 extends through the first opening 110 into the tank body 100 and connects to the guide member 400, allowing the motor 321 to drive the guide member 400 to rotate. The rotating guide member 400 can remove lignin adhering to its surface through centrifugal force, thereby preventing lignin from accumulating on the guide member 400. A protective cover 323 is also provided on the side of the support platform 320 facing the first opening 110, extending toward the first opening 110 and into the tank body 100. The protective cover 323 is mounted on the outside of the connecting rod 322 to protect the connecting rod 322 and prevent lignin from embedding in the connection gap and causing equipment failure.

[0026] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
