[0002] Refractory materials refer to a type of inorganic non-metallic materials with a refractoriness of not less than 1580°C. It is now defined as any material whose physical and chemical properties allow it to be used in a high temperature environment. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields. The largest amount is used in the metallurgical industry, accounting for 50% to 60% of the total output. Refractory materials need to be dried during the production process to facilitate the next step or storage. The existing refractory drying equipment has the defects of insufficient and uneven drying and low drying efficiency, which will affect the processing and use of refractory materials.

[0003] To this end, those skilled in the art have conducted research and improvements, such as the drying equipment for the production of refractory materials with application number CN202021023305.1. This technical solution can comprehensively tumble the refractory materials through its stirring mechanism, so that the refractory materials can be fully dried, and the drying efficiency is relatively high. Through its main mechanism, the stirring bin can be raised and lowered, so that the refractory materials can be quickly discharged, greatly improving production efficiency.

The output end of the blower is connected to an air outlet pipe. The end of the air outlet pipe is rotatably connected to the upper end of the hollow tube through a sealing bearing.

3. The high-efficiency drying device for refractory materials according to claim 2, characterized in that: A heating pipe is connected to the inner wall of the cover body. The heating pipe is arranged in a spiral structure. A heat insulation coating is coated on the outer wall of the cover body. The axis of the cover body coincides with the axis of the hollow tube.

4. An efficient drying device for refractory materials according to claim 1, characterized in that: A horizontal shaft is rotatably connected to the left side wall of the transmission housing. A worm gear is connected to the left end of the horizontal shaft, and a circular turntable is connected to the right end of the horizontal shaft. Two first pins are connected to the right end of the circular turntable. The end of the first pin is rotatably connected to a traction rod. The end of the traction rod is rotatably connected to the center of the U-shaped rod through a second pin. A forward and reverse motor is connected to the left side wall of the transmission housing. The output end of the forward and reverse motor is connected to a worm, and the worm is meshed with the worm gear.

5. The high-efficiency drying device for refractory materials according to claim 4, wherein: The two traction rods are arranged in a centrosymmetric structure with respect to the center of the circular turntable. When the distance between the two U-shaped rods is the smallest, the upper and lower ends of the annular seat are respectively in contact with the bottom wall of the gland and the top wall of the housing.

6. The operating method of an efficient drying device for refractory materials according to any one of claims 1-5, characterized in that, It includes the following steps: S1. Equipment assembly: Insert the T-shaped block into the travel groove along the travel groove to abut against the permanent magnet, so that the receiving cylinder is installed in the relief opening. S2. Material filling: Place the refractory material in the storage bin of the silo. When in use, open the electric valve plate, use the crushing roller to crush the falling agglomerated material, and the material falls into the receiving cylinder along the discharge channel. S3. Station switching: After the servo motor is started, it drives the gear to mesh with the driven gear, so that the central shaft drives the workbench to deflect, thereby realizing station switching. S4. Closing and docking: Use the infrared signal receiver to receive the signal emitted by the infrared signal transmitter, which is convenient for the PLC controller to control the operation of the electrical components. After the circular turntable deflects, the end of the traction rod drives the U-shaped rod to move, and the gland and the housing move closer and can be docked and closed with the annular seat. S5. Drying and stirring: The hollow tube extends into the receiving cylinder. After rotation, the stirring rod disperses the refractory material. Use the heating tube in the housing to heat the heat conduction cylinder to raise the temperature, and the drying operation of the refractory material can be realized. S6. Separation and exhaust: After drying, the forward and reverse motor rotates in reverse, and the two U-shaped rods move away from each other. Use the blower to introduce external air, and the gas is discharged along the air outlet holes, which can accelerate the discharge of the humid air in the cylinder and ensure the drying effect. S7. Material removal: Move the annular seat through the handle, and the T-shaped block moves out along the travel groove, and the dried material can be withdrawn from the workbench.
