[0022] Working principle: When in use, the raw materials are mixed and stirred by the feeding device 2 and preheated before entering the storage bin 101, the screw conveyor 102 is started, and the driving shaft of the arc-shaped guide plate 103 drives the spiral plate to rotate. The rotation of the spiral plate drives the raw materials to move, and the materials are sent to the heating device 3 for heating, melting, mixing and stirring, and defoaming treatment is performed at the same time, so as to reduce the bubbles in the raw materials, thereby improving the quality of the raw materials. At the same time, the setting of the arc-shaped guide plate 103 enables the raw materials to naturally descend under the action of gravity, and are concentrated to the middle position of the screw conveyor 102 under the arc-shaped guiding action of the arc-shaped guide plate 103, thereby avoiding the accumulation of raw materials at the corners to affect the processing efficiency and cause waste of resources, and at the same time avoid the increase of resistance caused by the accumulation of raw materials, thereby improving the conveying efficiency.

[0023] The feeding device 2 includes a feeding pipe 201, the top of which is fixedly connected to a stirring assembly 202, a particle feeding port 203 is fixedly connected to one side of the top of the stirring assembly 202, a lipid melting device 204 is fixedly connected to the side of the particle feeding port 203, a powder feeding port 205 is fixedly connected to the side of the lipid melting device 204 away from the particle feeding port 203, the bottoms of the lipid melting device 204 and the powder feeding port 205 are both connected to the top of the stirring assembly 202, and the bottom of the feeding pipe 201 is connected to the top of the storage bin 101.

[0025] Working principle: After the material is stirred by the stirring component 202, it reaches the surface of the arc-shaped material guide tube 207 under the action of gravity. Since the raw materials for manufacturing the waterproof grille include powder, liquid and solid substances, they are prone to adhesion after stirring, which affects the feeding efficiency. The electric heating wire 208 is set to heat the surface of the arc-shaped material guide tube 207, thereby melting the material on the surface of the arc-shaped material guide tube 207 and falling. At the same time, the arc design of the arc-shaped material guide tube 207 prolongs the residence time of the material inside the stirring component 202, thereby prolonging the stirring time inside the stirring component 202, so that the mixing is more complete, and the materials are more fully dissolved in each other.

The melted liquid substance passes through the inside of the rotating tube 2023 and is discharged through the lipid outlet 2025 under the guidance of the conical guide block 2026, so that the heated liquid substance is evenly sprinkled on the surface of the stirring plate 2024 through the lipid outlet 2025, so that the material and the liquid substance are fully mixed. The grooves on the surface of the stirring plate 2024 enable the material to be folded multiple times during stirring, thereby improving the stirring and mixing effect.

The material slides on the surface of the arc guide plate 2044. The arc heating block 2043 heats the surface of the arc guide plate 2044, so that the material is melted and reaches the inside of the rotating tube 2023 through the porous tube 2045. The porous tube 2045 blocks the solid raw material. When the solid raw material is melted into liquid, the material flows out from the side of the porous tube 2045. The setting of the conical block 2046 prevents the material from accumulating on the top of the porous tube 2045 and causing material accumulation. The melted material is sprinkled through the inside of the rotating tube 2023 so that the materials are fully mixed. The hydraulic raw material and the solid raw material are fully mixed before melting, thereby improving product quality.
