The heat transfer oil input and output terminals are connected. The two ends of the circulation pipe 601 are connected to the heat transfer oil input and output terminals of the heating equipment. Two heat transfer components, an outer jacket 5 and an inner jacket 6, are set to heat the material from both the inner and outer sides to avoid excessive temperature difference between the inner and outer materials. The heat transfer oil is circulated into the outer jacket 5 through the input pipe 501 and the output pipe 502 to ensure that the heat transfer oil in the outer jacket 5 is within the set range. The heat transfer oil flows through the circulation pipe 601 and then exchanges heat with the heat transfer oil in the inner jacket 6, so that the heat transfer oil in the inner jacket 6 is within the set range.
[0023] The top cover 2 is equipped with a stirring component 7 to stir the material, and the inner jacket 6 is equipped with a sensor assembly 8 to detect the temperature at various points and thus determine whether it meets the set requirements.
[0024] The mixing tank 1 is connected to the feed pipe 3, and the bottom of the mixing tank 1 is connected to the discharge pipe 4. A valve is installed at the connection between the discharge pipe 4 and the mixing tank 1.
[0025] The mixing component 7 includes a geared motor 701, which is fixedly installed on the top of the top cover 2. A rotating shaft 702 is fixedly installed at the output end of the geared motor 701. A connecting plate 703 is fixedly installed at the bottom end of the rotating shaft 702. The edge of the connecting plate 703 is rotatably connected to the inner wall of the top cover 2 through a sealed bearing. A mixing shaft 704 is rotatably connected to the connecting plate 703 through a bearing. The mixing shaft 704 extends into the mixing tank 1. A mixing blade 705 is fixedly installed on the outer wall of the mixing shaft 704. The geared motor 701 drives the rotating shaft 702 to rotate, which in turn drives the connecting plate 703 to rotate. The connecting plate 703 drives the mixing shaft 704 to perform a circular motion, which in turn drives the mixing blade 705 to perform a circular motion to mix the materials.
[0026] Four stirring shafts 704 are provided, and the four stirring shafts 704 are arranged in a circumferential array on the connecting plate 703. Gears 706 are fixedly installed on the outer wall of the stirring shafts 704. Gears 706 mesh with internal gear rings 707, which are fixedly installed on the inner wall of the top cover 2. When the stirring shafts 704 are driven by the connecting plate 703 to make circumferential motion, the gears 706 on the stirring shafts 704 are pushed by the internal gear rings 707 to rotate, thereby driving the stirring shafts 704 to rotate. The rotation of the stirring shafts 704 drives the stirring blades 705 to rotate, thereby further stirring the material.

[0028] Multiple sensor assemblies 8 are provided and distributed at different positions on the inner interlayer 6. The sensor assembly 8 includes a heat-conducting shell 801. A temperature sensor 802 is fixedly installed inside the heat-conducting shell 801. Multiple sensor assemblies 8 measure the temperature of the material at different positions. The heat-conducting shell 801 is set to protect the temperature sensor 802 and prevent the material from adhering to the temperature sensor 802.
[0029] Working principle: During use, the material is poured into the mixing tank 1, and then the heating equipment is turned on to introduce the heated heat transfer oil into the input pipe 501 and the circulation pipe 601, so that the heat transfer oil in the outer jacket 5 and the circulation pipe 601 circulate, thereby raising the temperature of the heat transfer oil in the outer jacket 5 and the inner jacket 6 to the set temperature. The geared motor 701 is turned on to drive the rotating shaft 702 to rotate, which in turn drives the connecting plate 703 to rotate. The connecting plate 703 drives the stirring shaft 704 to rotate, which in turn drives the stirring blades 705 to rotate and stir the material. When the stirring shaft 704 is driven by the connecting plate 703 to rotate, the gear 706 on the stirring shaft 704 is pushed by the internal gear ring 707 to rotate, which in turn drives the stirring shaft 704 to rotate. The rotation of the stirring shaft 704 drives the stirring blades 705 to rotate, thereby further stirring the material. After the material is mixed, the valve on the discharge pipe 4 is opened, and the material can be discharged from the discharge pipe 4.
