[0027] Working principle: The utility model is a stirred reactor for processing heat-insulating coatings. By setting a temperature control structure 4, a suitable temperature environment is provided for the processing and preparation of the mixed coating liquid inside the tank. When the temperature inside the tank is too low and not suitable for preparing the coating, high-temperature liquid can be introduced into the coil 44 through the water inlet 42, and the heat preservation property of the jacket 41 is used to reduce heat loss and provide a suitable preparation temperature for the inside of the tank. Then, the cooled high-temperature liquid is discharged through the water outlet 43 for heating. In this way, a suitable temperature can be provided for the inside of the tank. When the tank is prepared, the temperature is kept at a constant level. If the internal temperature is too high, low-temperature liquid can be injected into the coil 44 through the water inlet hole 42 and then flow out through the water outlet hole 43 to take out the heat of the mixed liquid in the tank body. The cycle is repeated until the temperature of the mixed liquid inside the tank body is suitable for preparation. The purpose of controlling the temperature of the mixed liquid inside the tank body is achieved through the setting of the temperature control structure 4, and the stirring preparation efficiency of the coating is improved. When the utility model starts to stir the mixed coating, the power stirring mechanism 7 is used to turn on the motor 71 to drive the first bevel gear 72, thereby rotating the second bevel gear 73 and the first shaft 74, and the rotation of the second bevel gear 73 The second shaft 77 fixedly connected to the third bevel gear 75 is driven to rotate accordingly, and the rotation direction of the first shaft 74 is exactly opposite to that of the second shaft 77. The forward and reverse rotation stirring reduces the vortex generated when the mixed liquid is stirred, which is conducive to fully stirring the mixed liquid and achieving the purpose of multi-directional radial stirring of the mixed liquid. When the first shaft 74 and the second shaft 77 rotate in opposite directions, the horizontal rotating rod 81 connected to the surface of the first shaft 74 is driven to rotate horizontally, and then the gear 82 arranged on the surface interacts with the circular rack 84 fixed to the bottom of the conical cover 85 to drive the horizontal rotating rod 81 to rotate horizontally. The rotating rod 81 rotates, thereby driving the vertical stirring rod 87 on the surface of the horizontal rotating rod 81 to rotate, thereby achieving the purpose of axial stirring of the mixed liquid. In addition, with the cooperation of the spiral blade 9 and the holes 10 arranged on the surfaces of the first shaft 74 and the second shaft 77 at both ends of the spiral blade 9, the spiral blade 9 can extract the mixed material settled at the bottom of the tank to the holes 10 on the upper part of the first shaft 74 and the second shaft 77 through the rotation of the first shaft 74, and then flow into the upper part of the tank body through the holes 10. Repeated extraction prevents the mixed liquid from settling at the bottom of the tank body, which is conducive to achieving the purpose of sufficient stirring of the mixed liquid.
