[0029] Working principle:
[0030] This thermal energy equipment uses a fine raw material mixing and blending machine. The raw materials enter the mixing and blending tank 1 through the feed pipe 3. A preliminary mixing component is also built into the feed pipe 3 to pre-mix the incoming raw materials. When the raw materials pass through the feed pipe 3, the stirring rod 13 on the preliminary stirring shaft 17 begins to rotate. This is driven by the servo motor 5 through a pulley transmission. The preliminary stirring shaft 17 is connected to the feed pipe 3 through a bearing on the connecting rod 16, ensuring the freedom and stability of rotation. The servo motor 5 drives the transmission shaft 18, which is connected to the secondary stirring shaft 19, which is equipped with stirring blades 20. When the transmission shaft 18 rotates, the secondary stirring shaft 19 also rotates, thereby deeply and carefully stirring the raw materials in the tank. The preliminary stirring and secondary stirring stages are used in combination to ensure that the raw materials have begun to mix before entering the mixing and blending tank 1, and are further mixed in the tank to achieve a uniform effect. The U-shaped support rod 7 is connected to the inner wall of the mixing and blending tank 1 to support the transmission shaft 18 and ensure its stability during the stirring process. The sealed bearing 21 provides frictionless rotation between the transmission shaft 18 and the U-shaped support rod 7 .
[0031] Power is provided by a servo motor 5 and transmitted to a preliminary mixing shaft 17 and a transmission shaft 18 via a connecting shaft 11, a driving pulley 14, a driven pulley 15, and a drive belt 12. This design allows for precise control of mixing speed and direction, and the mixed materials can be discharged through a discharge pipe 4, which is equipped with a valve 6 to control the outflow of materials.
