[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The present invention provides Figure 1-2 The method for continuously eliminating glass bubbles online with ultrasonic waves comprises the following steps:

[0034] S1: Setting a working pool, a working pool for glass liquid flow is set between the outlet of the glass furnace flow hole and the feed channel;

[0035] S2: Heating treatment: premixed natural gas burners are used on both sides of the working pool to keep the glass liquid temperature above 1350°C to reduce the viscosity of the glass liquid;

[0036] S3: Detection processing, detecting the flowing glass liquid and controlling the actuator to act;

[0037] S4: Position adjustment: punch a hole in the cover plate above the working pool, and insert the ultrasonic generator probe into the working pool by vertically inserting the actuator through the hole in the cover plate;

[0038] S5: Arrange the generators, and arrange the ultrasonic generators in two rows with equal distances along the glass liquid flow direction;

[0039] S6: Defoaming treatment, which allows the ultrasonic generator to work continuously and uninterruptedly to continuously remove the small bubbles remaining in the glass liquid;

[0040] S7: Secondary inspection: secondary inspection is performed on the glass liquid at the glass liquid outlet to detect the quality of the glass liquid after treatment.

[0041] A working pool is set at the rear end of the outlet of the glass furnace flow hole. According to the data detected by the sensor, the ultrasonic generator probe to be used is determined, and the appropriate ultrasonic generator is inserted into the glass liquid through the actuator. When the ultrasonic wave passes through the glass liquid, the tiny bubbles remaining in the glass liquid will be impacted by the sound wave to form small bubbles. When these small bubbles are connected together, a relatively large bubble will be formed, which will rise and be discharged from the glass liquid, thereby eliminating bubbles, enhancing the uniformity of the glass liquid, and improving the quality of the glass, which is easy to use.

[0042] In step S1, the depth of the working pool is between 300 and 500 mm, and the working pool is fixed between the outlet of the flow hole of the glass furnace and the feed channel by welding. The time for the glass liquid to pass through the ultrasonic working area of ​​the working pool is between 20 and 30 minutes. The depth of the working pool is set between 300 and 500 mm, and it is fixed at a specific position by welding, which can provide a relatively stable flow space for the glass liquid, so that the glass liquid flows relatively smoothly therein, avoiding the flow disorder of the glass liquid due to inappropriate depth or loose fixation. The time for the glass liquid to pass through the ultrasonic working area of ​​the working pool is controlled between 20 and 30 minutes, which is conducive to the full effect of the ultrasonic wave on the glass liquid in this area, and more effective defoaming and other treatments are performed to ensure that the bubbles in the glass liquid can be fully eliminated, thereby improving the quality of the glass and the stability of production.

[0043] Specifically, the detection process in step S3 includes the following steps:

[0044] S31: Information collection and processing, which collects various status information of the glass liquid in real time through sensors and transmits the data to the control system, so as to obtain the actual situation of the glass liquid in a timely and accurate manner and provide a reliable data basis for subsequent processing;

[0045] S32: Control instruction generation: the control system analyzes the information transmitted by the sensor and makes a judgment. Based on the judgment result, the control instruction is automatically generated and transmitted to the actuator, realizing an automated control process without frequent manual intervention, improving production efficiency and stability, and reducing the impact of human errors on the production process;

[0046] S33: Execute the action. The actuator receives the control command and drives the ultrasonic generator probe to make corresponding actions. The actuator can quickly and accurately receive the control command and make corresponding actions, ensuring that the ultrasonic generator probe can be adjusted and operated in time according to the state of the glass liquid, so as to better play the role of ultrasound, effectively deal with bubbles in the glass liquid, and ensure the quality of glass products.

[0047] Specifically, the sensor in step S31 includes:

[0048] The bubble detection sensor is used to monitor the changes in the bubble content in the glass liquid in real time through optical and acoustic principles, and can timely and accurately capture the dynamic conditions of the generation, aggregation and dissipation of bubbles in the glass liquid. This allows the state of bubbles in the glass liquid to be known at any time during the entire production process, so that defoaming measures can be taken in time to effectively avoid excessive bubbles from having adverse effects on the glass quality;

[0049] Temperature sensors are used to measure the temperature changes of glass liquid in real time, allowing operators to understand the temperature status of glass liquid at any time. Because the temperature of glass liquid has an important influence on its physical properties and production process, the appropriate temperature range can ensure that the fluidity, viscosity and other characteristics of glass liquid are in good condition, which is conducive to subsequent processing and treatment. By timely monitoring temperature changes, process parameters such as heating or cooling can be adjusted in time to ensure that the glass liquid always remains within the appropriate temperature range, ensuring the smooth progress of production and the quality of glass products;

[0050] Viscosity sensors are used to monitor the viscosity changes of glass liquid in real time. Viscosity is one of the important physical properties of glass liquid, which directly affects the flow performance and molding performance of glass liquid. By real-time monitoring of viscosity changes, abnormal fluctuations in viscosity can be discovered in time, such as changes in viscosity caused by temperature changes, composition changes, etc., so as to adjust the production process in time, such as adjusting the heating power, adding specific ingredients, etc., to maintain the stability of glass liquid viscosity and ensure the molding quality and production efficiency of glass.

[0051] Furthermore, in step S32, the control system is one of an embedded system and an industrial computer. According to preset algorithms and rules, the control system judges the state information of the glass liquid, calculates the appropriate probe and immersion depth adjustment value according to the judgment result, and sends corresponding control instructions.

[0052] Furthermore, in step S33, the actuator is a telescopic push rod and a motor. According to the control instruction, ultrasonic generator probes of different shapes can be selected for use through the actuator, and the depth of the ultrasonic generator probe in the glass liquid can be adjusted according to the control instruction.

[0053] In step S4, the ultrasonic generator probe includes a spiral edge probe 1 and a sawtooth edge probe 2, such as Figure 2 As shown, the spiral edge probes 1 and the sawtooth edge probes 2 are arranged in two rows at equal intervals and staggered.

[0054] Temperature judgment and selection: When it is detected that the glass liquid temperature is high and the temperature rises quickly, it indicates that the glass liquid is in an overheated state. At this time, if the flow of the glass liquid is relatively turbulent, the spiral edge probe 1 can generate a more complex ultrasonic field due to its spiral structure, which is more conducive to promoting thermal convection inside the glass liquid, thereby more effectively reducing the temperature. Therefore, the spiral edge probe 1 will be selected, and the appropriate immersion depth adjustment value will be calculated according to the degree of temperature rise, the flow state of the glass liquid, etc. For example, the immersion depth may be appropriately deepened for deeper thermal regulation. If the glass liquid temperature is low and needs to be heated up quickly, the ultrasonic field characteristics of the serrated edge probe 2 may be more conducive to concentrated energy for local heating. The control system will judge and select the serrated edge probe 2, and at the same time calculate the immersion depth adjustment value according to the temperature increase requirement. The immersion depth may be appropriately adjusted to heat a specific area more accurately.

[0055] Viscosity judgment and selection: When it is detected that the viscosity of the glass liquid gradually increases and the increasing trend is obvious, it means that the fluidity of the glass liquid has deteriorated. The ultrasonic effect of the spiral edge probe 1 can better break the resistance to flow caused by the increase in viscosity and promote the flow of the glass liquid. The control system will select the spiral edge probe 1 and calculate the immersion depth adjustment value according to the amplitude of the viscosity increase. For example, the immersion depth is appropriately increased to enhance the viscosity regulation effect. If the viscosity of the glass liquid begins to decrease and has a trend of continuing to decrease, the ultrasonic field of the serrated edge probe 2 is more conducive to maintaining the glass liquid within a suitable viscosity range. The control system will select the serrated edge probe 2 and then calculate the immersion depth adjustment value according to the viscosity reduction. The immersion depth may be appropriately adjusted to maintain stable control of the viscosity.

[0056] Judgment and selection of bubble size: If it is found that the bubbles in the glass liquid are large and numerous, the ultrasonic effect of the spiral edge probe 1 can stir the glass liquid more vigorously and help the bubbles rise and burst better. The control system will select the spiral edge probe 1 and calculate the immersion depth adjustment value according to the size and number of the bubbles. For example, the immersion depth may be appropriately deepened to more efficiently process the bubbles. When the bubbles in the glass liquid are small and dispersed, the ultrasonic effect of the serrated edge probe 2 is more suitable for processing these dispersed small bubbles. The control system will select the serrated edge probe 2 and calculate the immersion depth adjustment value according to the specific situation of the bubbles. The immersion depth may be appropriately adjusted to more accurately act on the small bubbles.

[0057] Furthermore, in step S5, the spacing between the ultrasonic generators is between 600 and 800 mm, the power of the ultrasonic generator is 3000 W, and the frequency of the ultrasonic generator is between 40000 and 60000 Hz. The spacing between 600 and 800 mm can ensure a relatively uniform ultrasonic field distribution in media such as glass liquid. If the spacing is too small, the ultrasonic waves may interfere with each other, resulting in energy superposition or cancellation, affecting the overall effect. If the spacing is too large, it may cause insufficient ultrasonic coverage in some areas, and comprehensive and effective treatment cannot be achieved. The ultrasonic generator power of 3000 W can provide sufficient energy to drive the ultrasonic wave to propagate and produce effects in the medium. Higher power means that stronger ultrasonic vibrations can be generated, which has a more significant impact on the physical or chemical processes of media such as glass liquid, such as promoting stirring, accelerating chemical reactions, etc. The frequency of the ultrasonic generator is between 40,000 and 60,000 Hz. This frequency range is suitable for producing effective ultrasonic effects in many media. Higher frequencies can make ultrasonic waves have stronger penetration and finer energy distribution, which helps to accurately process media such as glass liquid, such as improving fine structures and removing impurities. It can also avoid problems such as large energy loss or adverse effects on the medium that may occur when the frequency is too low.

[0058] The secondary inspection in step S7 uses an optical detector and an ultrasonic detector to observe the transparency and bubbles of the glass liquid to determine whether the quality of the treated glass liquid meets the expected standards, thereby comprehensively evaluating the quality of the treated glass liquid.
