[0015] like Figure 1As shown, this utility model proposes an automatic quartz sand baking device, which consists of a control system and two sets of baking components arranged side by side in the transverse direction. Each baking component includes a support 20, on which an oven 8 is fixedly mounted. The oven 8 is square in shape with a cavity in the middle, and a quartz sand baking tube 2 is disposed within the cavity. Two circular through holes are opened on each of the two sides of the oven 8 along its length, and the two ends of the quartz sand baking tube 2 extend outward through these circular through holes. A drive mechanism is provided on both sides of the oven 8. The drive mechanism consists of a retaining wheel 1, two support wheels 3, and a drive motor 6. The two support wheels 3 are fixedly mounted on both sides of the support 20, and each support wheel 3 is provided with a grooved track. The retaining wheel 1 is disposed within the grooved track and supported by the two support wheels 3. The retaining wheel 1 is sleeved on the quartz sand baking tube 2 and fixedly connected to it. The drive motor 6 is fixedly installed at the lower part of the bracket 20 and connected to the bracket wheels 3 via belt drive or other transmission methods. The drive motor 6 drives the two bracket wheels 3 to rotate, which in turn drives the retaining wheel 1 to rotate, thereby driving the quartz baking tube 2 to rotate. The bracket 20 is also equipped with a drive shaft 4, which is connected to the bracket 20 via bearings and its two ends are respectively connected to the bracket wheels 3 on both sides of the oven 8 for synchronizing the movement of the bracket wheels 3 on both sides of the oven 8.

[0016] A heating mechanism is also provided below the quartz sand-baking tube 2. The heating mechanism consists of 18 silicon carbide rods 7 and thermocouples 19. The 18 silicon carbide rods 7 are evenly distributed below the quartz sand-baking tube 2 and are fixedly connected to the oven 8 for uniform heating of the quartz sand-baking tube 2. The thermocouples 19 are S-type thermocouples with a temperature range of 0-1600℃, arranged side by side with the silicon carbide rods 7 and fixedly connected to the oven 8 for real-time temperature measurement of the quartz sand-baking tube 2.

[0017] Preferably, the diameter of the quartz sand-baking tube 2 in the first sand-baking assembly is 150mm; the diameter of the quartz sand-baking tube 2 in the second sand-baking assembly is 200mm, and the second section of the quartz sand-baking tube 2 is fitted onto the first section of the quartz sand-baking tube 2 in a series connection, forming an overlapping portion with a length of 10mm. Simultaneously, the quartz sand-baking tubes 2 in both sets of sand-baking assemblies are arranged at an inclined angle of 30° to ensure the continuity of quartz sand transfer between the two quartz sand-baking tubes 2.

[0018] Preferably, the oven 8 is also equipped with a heat preservation mechanism, which is composed of a layer of heat preservation bricks 5 and a layer of heat preservation cotton 9. Both the heat preservation bricks 5 and the heat preservation cotton 9 are arranged on both sides of the quartz baking sand tube 2, with the heat preservation bricks 5 located on the outer side and the heat preservation cotton 9 located on the inner side.

[0019] The control system is composed of a PLC controller 11, an AD module 12, a DA analog signal module 13, a temperature transmitter module 14, a three-phase voltage regulator module 15, a frequency converter 16, a touch screen 17, and an electricity meter 18. The temperature transmitter converts the temperature value measured by the thermocouple 19 into a one-to-one analog 4-20mA current signal, and inputs the obtained analog current signal to the AD module 12. The AD module 12 then converts the analog current signal into a corresponding digital signal, which is then provided to the DA analog signal module 13. The DA analog signal module 13 then converts the digital signal provided by the AD module 12 into a corresponding 0-10V analog voltage signal, which is provided to the three-phase voltage regulator module 15. The three-phase voltage regulator module 15 then controls the 18 heated silicon carbide rods 7, thereby realizing automatic control of the heating process. The PLC controller 11 and touch screen 17 are used to program the system heating program using a PID control system. The temperature transmitter collects the temperature, converts it into an analog signal, and sends this analog signal to the AD input module. Then, the DA analog signal module 13 outputs the signal to the automatic heating control terminal of the three-phase voltage regulation module 15, which automatically adjusts the temperature based on the temperature difference between the set value and the feedback value. Utilizing the PID instruction control method in the PLC program, the heating process can be controlled relatively reasonably. The outputs of the proportional, integral, and derivative components are added together to obtain the final control quantity, allowing for real-time adjustment of the control system output. This enables the system to quickly and stably reach the set value, achieving precise control. The meters 18 include three voltmeters and three ammeters. The three voltmeters are installed at the output terminal of the three-phase voltage regulation module 15, which controls the silicon carbide heating element 7. The three ammeters are also installed at the output terminal of the three-phase voltage regulation module 15 to observe any abnormalities at the heating load terminal.

[0020] This invention places a quartz sand-baking tube 2 inside an oven 8, and sets drive mechanisms on both sides of the quartz sand-baking tube 2 to drive its rotation. At the same time, a silicon carbide rod 7 and a thermocouple 19 are set under the quartz sand-baking tube 2 to realize the real-time detection of the temperature of the quartz sand-baking tube 2 while heating it. Then, the control system controls the rotation of the quartz sand-baking tube 2 and the heating of the silicon carbide rod 7 in a coordinated manner to realize the automatic sand-baking process.
