Description

Technical Field

[0001] This utility model belongs to the field of electronic glass manufacturing technology, specifically relating to a stable stirring system for electronic glass production. Background Technology

[0002] In the field of electronic glass production, the stirring system is one of the most critical pieces of equipment, directly impacting product quality. However, traditional stirring structures often separate the cover brick and the stirring rod, with the cover brick fixed while only the stirring rod rotates. This creates a gap between the two, a weak point for heat loss, easily leading to sudden temperature drops and the precipitation and accumulation of condensate, resulting in product defects. Furthermore, the stability of the stirring rod during operation is crucial, affecting the safety of the stirring system and the uniformity of the molten glass. In traditional stirring structures, due to centrifugal force and fluid resistance, the stirring rod is prone to shaking and shifting during operation. This shaking and shifting intensifies with increasing operating time, affecting the uniformity and efficiency of the stirring process. Utility Model Content

[0003] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a stable stirring system for electronic glass production. By integrating the cover brick and the stirring rod into a single unit, the system can maintain synchronous movement between the cover brick and the stirring rod, solving the problem of product defects caused by the precipitation, accumulation, and fall of condensate due to rapid temperature loss near the gap. Simultaneously, by precisely matching a roller structure to a specially designed track on one side of the cover brick, the synchronous movement of the cover brick and the stirring rod is achieved, while also providing a stable additional support system for the stirring rod. This effectively suppresses the shaking and deviation of the stirring rod caused by centrifugal force, fluid resistance, and other factors during operation, ensuring that the stirring rod remains in a stable operating state. This not only improves the stability of the stirring process but also effectively extends the service life of the stirring system.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a stable stirring system for electronic glass production, including a stirring tank, stirring rod, cover brick, track groove, roller structure and receiving groove; The stirring rod is placed concentrically inside the mixing tank, and the cover brick is located above the mixing tank. The cover brick consists of a hollow cone top and a hollow cylindrical part below the hollow cone top. The stirring rod is located at the center of the hollow cone top and is rigidly connected to the hollow cone top. The mixing tank opening is circumferentially provided with a receiving groove and a track groove from the inside out. The bottom of the hollow cylindrical part of the cover brick is connected to a roller structure, and the roller structure is placed on the track groove and can move along the track groove.

[0005] In one embodiment, the mixing tank is connected to a mixing inlet and a mixing outlet, wherein the mixing inlet and the mixing outlet are located on opposite sides of the mixing tank.

[0006] In one embodiment, the stirring inlet is located higher than the stirring outlet.

[0007] In one embodiment, the outside of the mixing tank is covered with a heat-insulating material; the heat-insulating material adopts a sloping structure that slopes outward from top to bottom in the circumferential area near the opening of the mixing tank, and the sloping structure is evenly distributed in a circumferential direction around the axis of the mixing tank to form a continuous conical transition surface.

[0008] In one embodiment, one side of the stirring rod is connected to the motor via a chain.

[0009] In one embodiment, the cover brick is filled with refractory material and uniformly coated with a layer of precious metal on the outside.

[0010] In one embodiment, a self-heating component is provided in the cover brick, which is a heating wire pre-embedded in the refractory material.

[0011] In one embodiment, the vertically shaded portion of the hollow cylindrical part of the cover brick is within the range of the receiving groove.

[0012] In one embodiment, there is a gap between the hollow cylindrical portion of the cover brick and the receiving trough.

[0013] This utility model also provides a method of using a stable stirring system for electronic glass production, which includes the following steps based on the above-mentioned stable stirring system for electronic glass production: The molten glass flows into the mixing tank and flows out after being stirred by the stirring rod. During the stirring process, the roller structure moves along the track groove, and the stirring rod and the cover brick rotate synchronously.

[0014] It also includes the material receiving process, as follows: The high-temperature gas generated by stirring, carrying condensate, flows upward. The self-heating component in the cover brick heats up the gas and maintains the temperature as the gas flows through the area between the cover brick and the stirring rod until the gas flows to the vicinity of the gap between the cover brick and the receiving trough and comes into contact with the outside air. The condensate in the gas begins to condense and precipitate out and falls into the receiving trough.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention provides a stable stirring system for electronic glass production. The integrated design of the cover brick and stirring rod achieves synchronized movement, eliminating the gap problem inherent in separate designs. This solves the problem of condensate buildup and falling due to rapid temperature loss near the gap, leading to product defects. Furthermore, the system shifts the condensate buildup location outwards, further preventing defects caused by condensate falling and improving product quality. The integrated design, with rollers on one side of the cover brick precisely fitted to a specially designed track, ensures synchronized movement of both the cover brick and stirring rod, while providing a stable additional support system for the stirring rod. This effectively suppresses shaking and deviation caused by centrifugal force and fluid resistance during operation, ensuring stable operation of the stirring rod. This not only improves the stability of the stirring process but also effectively extends the service life of the stirring system. Attached Figure Description

[0026] This invention provides a stable stirring system for the production of electronic glass.

[0027] On one hand, a stable stirring system for electronic glass production is provided, including a stirring tank 1, a stirring rod 5, a cover brick 8, a track groove 9, a roller structure 10, and a receiving groove 11; the stirring rod 5 is placed concentrically in the stirring tank 1, and the cover brick 8 is located above the stirring tank 1; the cover brick 8 is composed of a hollow cone top and a hollow cylindrical part below the hollow cone top (the top of the cover brick 8 is inclined outwards around the stirring rod 5 and the sides are vertical), the stirring rod 5 is set at the center of the hollow cone top, and the stirring rod 5 is rigidly connected to the hollow cone top; the receiving groove 11 and the track groove 9 are arranged circumferentially from the inside to the outside at the opening of the stirring tank 1; the bottom of the hollow cylindrical part is connected to the roller structure 10, and the roller structure 10 is placed on the track groove 9 and can move along the track groove 9.

[0028] On the other hand, a method for using a stable stirring system for electronic glass production is provided, including the following steps: molten glass flows into the stirring tank 1 and flows out after being stirred by the stirring rod 5. During the stirring process, the roller structure 10 moves along the track groove 9, and the stirring rod 5 and the cover brick 8 operate synchronously.

[0029] Furthermore, the above-mentioned method of use also includes a material receiving step: the high-temperature gas generated by stirring and carrying condensate flows upward, the self-heating component in the cover brick 8 heats up, and the temperature is maintained when the gas flows through the area between the cover brick 8 and the stirring rod 5 until the gas flows to the vicinity of the gap between the cover brick 8 and the material receiving tank 11 and comes into contact with the outside air, the condensate in the gas begins to condense and precipitate, and falls into the material receiving tank 11.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings: See Figures 1-3 This embodiment provides a stable stirring system for electronic glass production, including 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 to the cover brick 8; the top of the cover brick 8 is designed to be inclined outwards from the stirring rod 5 as the center, and the side is designed to be vertical; the opening of the stirring tank 1 is provided with a receiving groove 11 and a track groove 9 in sequence outwards; the bottom of the side (hollow cylindrical part) of the cover brick 8 is connected to a roller structure 10, and the roller structure 10 is placed on the track groove 9.

[0031] Furthermore, the insulation material 4 in contact with the opening of the mixing tank 1 has a certain circumferential slope, specifically the mixing tank 1 is covered with insulation material 4; the insulation material 4 adopts a sloped structure from top to bottom and outward in the circumferential area near the opening of the mixing tank 1, and the sloped structure is evenly distributed around the axis of the mixing tank 1 to form a continuous conical transition surface. The slope angle can be 15°-30°.

[0032] The inclined surface is used to prevent volatiles from condensing here. After condensation, they will fall into the receiving trough and prevent them from falling into the mixing tank. This further solves the problem of condensate falling due to structural defects at the opening of the traditional mixing tank 1.

[0033] More specifically, the cover brick 8 consists of a hollow cone top and a hollow cylindrical section below the hollow cone top. A stirring rod 5 is positioned at the center of the hollow cone top and is rigidly connected to it. The stirring tank 1 is connected to the stirring inlet 2 and the stirring outlet 3, respectively, with the stirring inlet 2 and the stirring outlet 3 located on opposite sides of the stirring tank 1, and the stirring inlet 2 positioned higher than the stirring outlet 3. The vertically shaded portion of the side (hollow cylindrical section) of the cover brick 8 is within the range of the receiving trough 11; a gap exists between the side (hollow cylindrical section) of the cover brick 8 and the receiving trough 11.

[0034] Furthermore, one side of the stirring rod 5 is connected to the motor 6 via a chain 7, and the outside of the stirring tank 1 is covered with insulating material 4. The cover brick 8 is filled with refractory material and uniformly covered with a layer of precious metal, with heating wires pre-embedded in the refractory material. A self-heating component is provided in the cover brick 8, which is a heating wire pre-embedded in the refractory material.

[0035] See Figure 2 and Figure 3 This embodiment also provides a method for using a stable stirring system for electronic glass production, including: a. Glass liquid stirring rod homogenization method: The glass liquid flows into the stirring tank 1 from the stirring inlet 2, and after being homogenized by the stirring rod 5, it flows out from the stirring outlet 3; b. Method to prevent condensate from accumulating and falling: During the stirring of the molten glass, the high-temperature gas carrying condensate flows upward. Because the cover brick 8 and the stirring rod 5 are integrated, and the cover brick 8 has a self-heating function, the temperature of the gas will not drop suddenly when it flows through the area of ​​the cover brick 8 and the stirring rod 5. The temperature will drop sharply only when the high-temperature gas flows to the vicinity of the gap between the cover brick 8 and the receiving tank 11, because it is in 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] Furthermore, the motor 6 can control the forward and reverse rotation of the stirring rod 5, and can also control its rotation frequency.

[0037] Furthermore, the stirring rod 5 is rigidly connected to the cover brick 8, which ensures that the stirring rod 5 and the cover brick 8 operate synchronously during normal operation.

[0038] Furthermore, the stirring rod system is equipped with a temperature sensor, not limited to welded or inserted thermocouples, to detect the temperature of the molten glass in the stirring tank 1 and the space near the cover brick 8. By connecting an external power source and adjusting the current, the heating wire can enable the cover brick to achieve self-heating, precisely maintaining the required temperature environment.

[0039] The self-heating function of the cover brick 8 is based on the heating wire being energized and heated. Combined with temperature sensor feedback and controller adjustment, a closed-loop control is formed to accurately maintain the temperature of the cover brick 8 and its surroundings. The following are the specific implementation details and connection relationships: The heating element is a heating wire (such as nickel-chromium alloy wire, iron-chromium-aluminum alloy wire, etc.) pre-embedded inside the refractory material of the cover brick 8, which serves as the direct actuator for self-heating.

[0040] The power input process is as follows: Both ends of the heating wire are led out to the outside of the cover brick 8 via high-temperature resistant wires. The wires must be covered with high-temperature resistant materials such as ceramic fiber braided tubing or magnesium oxide insulating tubing to prevent short circuits due to insulation failure at high temperatures. The ends of the wires are connected to an external power interface (such as ceramic terminal blocks) for easy connection to the control system. Specifically, both ends of the heating wire are connected to an external power source (usually low-voltage DC or AC power) via terminal blocks to form a heating circuit. The power supply must have voltage / current regulation capabilities (such as an adjustable DC power supply or a thyristor voltage regulator module).

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

[0042] The power supply is used to provide a stable DC or AC power (depending on the heating wire material, such as nickel-chromium wire which is usually suitable for AC), and the output voltage and current are adjustable (e.g., 0-220V adjustable, the power range is designed according to the volume of the cover brick and the heating requirements, usually from hundreds of watts to thousands of watts).

[0043] The temperature controller can be a PLC (Programmable Logic Controller) or a dedicated temperature control module (such as a PID controller) with a built-in temperature setting program. The controller receives feedback signals from the temperature sensor and adjusts the current input to the heating wire in real time to achieve precise temperature control. The input power of the heating wire is adjusted using methods such as SCR voltage regulation and pulse width modulation (PWM). For example, when the temperature of the cover brick 8 is lower than the set value, the controller increases the current (increases power) to accelerate heating; when the temperature approaches the target value, it decreases the current (reduces power) to maintain stability.

[0044] The positive terminal of the external power supply is connected to the ceramic terminal through a high-temperature resistant wire. The current is introduced into the resistance heating wire embedded in the refractory material of the cover brick 8 through the terminal, and then returns to the negative terminal of the power supply through the ceramic terminal and the high-temperature resistant wire on the other side, forming a closed circuit. 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] Furthermore, to ensure insulation and safety, the heating wire and the refractory material must be wrapped with high-temperature resistant insulating material (such as alumina ceramic fiber or mica sheet) to prevent short circuits; an insulating gasket must be installed between the wiring terminal and the metal shell (outer precious metal layer) of the cover brick 8 to prevent leakage.

[0046] Furthermore, in order to ensure that the heating wires are evenly distributed in the refractory material (such as by pre-embedding them in a spiral or mesh pattern), the overall temperature of the cover bricks is uniform, avoiding local overheating or underheating.

[0047] Temperature sensors (such as K-type thermocouples, platinum resistance thermometers, Pt100, etc.) are pre-embedded on or inside the cover brick 8. The sensor position should be close to the heating wire distribution area 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 closed-loop control system where the sensor detects the real-time temperature of the cover brick 8, the controller compares the set temperature with the actual temperature, and then adjusts the heating wire current to change the temperature of the cover brick 8. The sensor then provides feedback again for cyclical control.

[0048] The controller adjusts the heating power in real time based on temperature changes during the stirring of the molten glass (such as heat loss due to gas flow) to ensure stable temperature in the area between the cover brick and the stirring rod, preventing premature condensation of condensates in the gas (high temperature must be maintained until the gas reaches near the gap in the receiving tank 11). Furthermore, a fuse or circuit breaker is installed in the power circuit to automatically cut off the power when the current exceeds the rated value of the heating wire. The controller sets a safe upper temperature limit (e.g., 50-100°C higher than the target temperature). When the sensor detects that the temperature exceeds the upper limit, an alarm is triggered and heating is forcibly stopped.

[0049] Regular cleaning of the material trough 11 can effectively prevent the accumulation of condensate and maintain the stable operation of the mixing system.

[0050] During the operation of the mixing system, the wear between the track groove 9 and the roller structure 10 is controlled within a certain range, and both can be replaced according to the wear condition.

[0051] The above content is only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed in this utility model shall fall within the scope of protection of the claims of this utility model.
