[0030] The present application will be further described in detail below with reference to the accompanying drawings: Referring to Figs. 1-3 The embodiment provides a stable stirring system for electronic glass production, which comprises a stirring tank 1, a stirring rod 5 and a cover brick 8; the stirring rod 5 is placed in the stirring tank 1 and is placed concentrically; the stirring rod 5 is connected with the cover brick 8; the top of the cover brick 8 is designed to be inclined to the four directions with the stirring rod 5 as the center, and the side part is designed to be vertical; the opening part of the stirring tank 1 is sequentially provided outwardly and peripherally with a receiving trough 11 and a track groove 9; the bottom of the side part (hollow cylindrical part) of the cover brick 8 is connected with a roller structure 10, and the roller structure 10 is placed on the track groove 9.

[0031] Further, the heat preservation material 4 in contact with the opening part of the stirring tank 1 is peripherally provided with a certain slope, and specifically, the stirring tank 1 is coated with the heat preservation material 4; the heat preservation material 4 is provided with a slope structure inclined outward from top to bottom in the peripheral area close to the opening part of the stirring tank 1, and the slope structure is uniformly distributed in a ring shape around the axis of the stirring tank 1 to form a continuous conical transition surface. The inclination angle of the slope can be 15°-30°.

[0032] The slope is used to prevent volatilization from condensing here, and the condensed volatilization also falls into the receiving trough, preventing the volatilization from falling into the interior of the stirring tank, and further solving the problem of the condensed volatilization falling caused by the structural defects of the opening part of the traditional stirring tank 1.

[0033] More specifically, the cover brick 8 is composed of a hollow conical top part and a hollow cylindrical part below the hollow conical top part, the stirring rod 5 is arranged at the center of the hollow conical top part, and the stirring rod 5 is rigidly connected with the hollow conical top part; the stirring tank 1 is connected with a stirring inlet 2 and a stirring outlet 3, wherein the stirring inlet 2 and the stirring outlet 3 are located on the two sides of the stirring tank 1 and the position of the stirring inlet 2 is higher than that of the stirring outlet 3. The vertical shadow part of the side part (hollow cylindrical part) of the cover brick 8 is within the range of the receiving trough 11; there is a gap between the side part (hollow cylindrical part) of the cover brick 8 and the receiving trough 11.

[0034] Further, one side of the stirring rod 5 is connected with a motor 6 through a chain 7, and the stirring tank 1 is coated with a heat preservation material 4. The inside of the cover brick 8 is filled with a fire-resistant material, the outside is uniformly coated with a layer of noble metal, and a heating wire is embedded in the fire-resistant material. A self-heating part is arranged in the cover brick 8, and the self-heating part is a heating wire embedded in the fire-resistant material.

[0035] Referring toFig. 2 and Fig. 3 The embodiment also provides a method for using the stable stirring system for electronic glass production, which comprises the following steps: a. Glass liquid stirring rod homogenization method: the glass liquid flows into the stirring tank 1 from the stirring inlet 2, and flows out from the stirring outlet 3 after being stirred by the stirring rod 5; b. Method for preventing condensate accumulation and falling: during the stirring of the glass liquid, the high-temperature gas carrying the condensate flows upwards. Since the cover brick 8 and the stirring rod 5 are designed in an integrated manner, and the cover brick 8 has a self-heating function, the temperature of the gas flowing through the area between the cover brick 8 and the stirring rod 5 does not decrease sharply. Until the high-temperature gas flows to the gap between the cover brick 8 and the receiving tank 11, the temperature begins to drop sharply due to direct contact with the outside air. At this time, the condensate in the gas begins to condense and fall into the receiving tank 11.

[0036] Further, the motor 6 can realize forward rotation and reverse rotation control of the stirring rod 5, and the frequency of rotation can be controlled.

[0037] Further, the stirring rod 5 and the cover brick 8 are rigidly connected, which can ensure that the stirring rod 5 and the cover brick 8 operate synchronously in normal operation.

[0038] Further, the stirring rod system is provided with a temperature sensor, which is not limited to a welded or inserted thermocouple, for detecting the temperature of the glass liquid in the stirring tank 1 and the space near the cover brick 8. Through the adjustment of the power supply and the current, the heating wire can promote the cover brick to realize the self-heating function and accurately maintain the required temperature environment.

[0039] The self-heating function of the cover brick 8 is realized by heating the heating wire through power supply, combined with temperature sensor feedback and controller adjustment, to form a closed loop control and accurately maintain the temperature of the cover brick 8 and the surrounding area. The following are the specific implementation details and connection relationship: the heating element is a heating wire (such as nichrome wire, iron-chromium-aluminum alloy wire, etc.) embedded in the refractory material of the cover brick 8, which is the direct execution element of self-heating.

[0040] The process of power input is as follows: the two ends of the heating wire are led out to the outside of the cover brick 8 through high-temperature-resistant wires. The wires need to be covered with a ceramic fiber braided sleeve or a magnesium oxide insulating tube made of high-temperature-resistant materials to prevent short circuit due to insulation failure in a high-temperature environment. The ends of the wires are connected to external power supply interfaces (such as ceramic terminals) for easy connection with the control system. Specifically, the two ends of the heating wire are connected to the external power supply (usually low-voltage direct current or alternating current) through the terminals, forming a heating loop. The power supply needs to have voltage / current adjustment function (such as adjustable direct current power supply or silicon-controlled voltage regulation module).

[0041] The temperature is detected by a temperature sensor (welded or inserted thermocouple) installed on the surface or inside of the cover brick 8 (near the heating wire area), which detects the actual temperature of the cover brick in real time and outputs the temperature signal.

[0042] The power supply is used to provide stable direct current or alternating current power (depending on the heating wire material, such as nickel-chromium wire, which is usually suitable for alternating current), and the output voltage and current can be adjusted (for example, 0-220V adjustable, the power range is designed according to the volume of the cover brick 8 and the heating demand, usually hundreds to thousands of watts).

[0043] The temperature controller can use PLC (Programmable Logic Controller) or special temperature control module (such as PID controller), with built-in temperature setting program. The controller adjusts the current size of the input heating wire in real time by receiving the feedback signal of the temperature sensor, to achieve precise temperature control. The input power of the heating wire is adjusted by means of silicon-controlled voltage regulation, pulse width modulation (PWM), etc. For example, when the temperature of the cover brick 8 is lower than the set value, the controller increases the current (increases the power) to accelerate the heating; when the temperature approaches the target value, the current is reduced (the power is reduced) to maintain stability.

[0044] The positive electrode of the external power supply is connected to the ceramic terminal through high-temperature-resistant wire, and the current is introduced into the resistance heating wire embedded in the refractory material of the cover brick 8 through the terminal, and then returned to the negative electrode of the power supply through the ceramic terminal on the other side and high-temperature-resistant wire, forming a closed loop; When the current flows through the heating wire, Joule heat is generated due to the resistance effect, realizing the self-heating function of the cover brick 8.

[0045] Further, in order to ensure insulation and safety, the heating wire and the refractory material need to be wrapped with high-temperature-resistant insulation material (such as alumina ceramic fiber, mica sheet) to prevent short circuit; Insulating gaskets need to be provided between the terminal and the metal shell (external noble metal layer) of the cover brick 8 to prevent electric leakage.

[0046] Further, in order to ensure the uniform distribution of the heating wire in the refractory material (such as spiral or net-shaped pre-embedding), ensure the uniform temperature of the cover brick as a whole, and avoid local overheating or underheating.

[0047] A temperature sensor (such as K-type thermocouple, platinum resistance Pt100, etc.) is pre-embedded on the surface or inside of the cover brick 8, and the sensor position needs to be close to the distribution area of the heating wire to accurately reflect the actual temperature of the cover brick 8. The sensor signal is transmitted to the controller through a shielded wire, forming a sensor that detects the real-time temperature of the cover brick 8, which is then compared with the set temperature by the controller, and then the heating wire current is adjusted to change the temperature of the cover brick 8, and the sensor is feedback again for closed-loop control.

[0048] The controller adjusts the heating power in real time according to the temperature change during the glass liquid stirring process (such as heat loss caused by gas flow), ensures the temperature stability of the cover brick and the stirring rod area, and prevents the condensate in the gas from condensing too early (high temperature needs to be maintained until the gas reaches the gap near the receiving tank 11). Further, a fuse or circuit breaker is provided in the power supply circuit, which automatically cuts off the power supply when the current exceeds the rated value of the heating wire. The controller sets a safety temperature upper limit (such as 50-100℃ higher than the target temperature), and when the sensor detects that the temperature exceeds the upper limit, an alarm is triggered and the heating is forced to stop.

[0049] By regularly cleaning the receiving tank 11, the accumulation of condensate can be effectively prevented, and the stable operation of the stirring system can be maintained.

[0050] The wear and tear between the track groove 9 and the roller structure 10 during the operation of the stirring system is controlled within a certain range, and both can be replaced according to the wear and tear state.

[0051] The above is only to illustrate the technical idea of the present application, and cannot limit the protection scope of the present application. Any modification made according to the technical idea of the present application on the basis of the technical scheme falls within the protection scope of the claims of the present application.
