Technical Field

[0001] This utility model relates to the technical field of Ru porcelain processing equipment, and in particular to a Ru porcelain glazing device. Background Technology

[0002] In the traditional production process of Ru porcelain, glazing is the core process for forming a unique glaze texture. It is mostly completed using an open glazing box, which has a relatively simple structure, is easy to operate, and can meet the production needs of a certain scale.

[0003] The prior art discloses a glazing device for ceramic production with application number CN202420921037.7, which relates to the field of ceramic production technology. This utility model sets up a flipping component so that after the ceramic is dipped in glaze once, it can be rotated once, which can ensure that after the ceramic is moved out of the container, the glaze liquid inside is poured back into the container.

[0004] Ru porcelain glaze has a complex composition, usually containing a variety of minerals and additives. During the glazing process, some components in the glaze may produce harmful gases due to physical or chemical changes. Once inhaled, these gases can accumulate in the body and cause irreversible damage to the nervous system, hematopoietic system, and digestive system. Utility Model Content

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a Ru porcelain glazing device, including a glazing box, an annular air curtain machine is fixedly installed on the side surface of the glazing box by bolts, an L-shaped back plate is welded to the back of the glazing box, and a lead screw is installed between the glazing box and the L-shaped back plate, and a drive motor is installed at the end of the lead screw. A threaded sleeve is threadedly connected to the surface of the lead screw, and a glazing frame is welded to the side surface of the threaded sleeve. An air suction hood is welded to the front of the L-shaped back plate, an air suction pipe is welded to the upper surface of the air suction hood, and an external flange is installed at the end of the air suction pipe.

[0007] By adopting the above technical solution, an air curtain machine can form an air curtain barrier at the opening of the glazing box to block the diffusion of harmful gases. The suction pipe is connected to an external air purification device through an external flange, thereby using the external air purification device to extract and purify the air under the suction hood. The combination of the two can reduce the concentration of harmful gases in the workshop and reduce the risk of respiratory exposure for workers.

[0008] Furthermore, a recycling platform is welded to the front of the L-shaped back plate, and a recycling drawer is installed on the front of the recycling platform. A porous ceramic plate is placed and installed inside the recycling platform.

[0009] By adopting the above technical solution, and by setting a recycling platform on the front of the L-shaped back panel, along with a recycling drawer and a porous ceramic plate, the glaze dripping from the Ru porcelain on the glaze dipping rack can be collected in a timely and effective manner. The filtering effect of the porous ceramic plate can trap impurities in the glaze, so that the recycled glaze can meet the standards for reuse, which greatly improves the glaze recycling rate and significantly reduces production costs.

[0010] Furthermore, corrugated tubes are installed on the inner bottom surface of the glazing box and the inner top surface of the L-shaped back plate, and the corrugated tubes are sleeved on the outer side of the lead screw. The other ends of the two corrugated tubes are fixedly connected to the threaded sleeve.

[0011] By adopting the above technical solution, the bellows seals the screw rod, preventing glaze splashing or harmful gases from corroding the screw rod, avoiding rust on mechanical parts, extending the service life of the equipment, and reducing the maintenance frequency.

[0012] Furthermore, an agitator is installed inside the glazing box, and the agitator is connected to an agitator motor via a coupling, with the agitator motor mounted on the lower surface of the glazing box.

[0014] Furthermore, a resistance heater is installed inside the glazing box, and a temperature sensor is installed on the inner side of the glazing box.

[0015] By adopting the above technical solutions, the glaze temperature can be precisely controlled to adapt to the melting characteristics of different glazes (such as the melting temperature requirements of lead oxide glaze), thereby reducing glaze surface defects caused by temperature fluctuations.

[0016] Furthermore, an integrated controller is bolted to the side surface of the glazing box.

[0017] By adopting the above technical solutions, the automated control of functions such as driving, stirring, and heating is integrated, supporting parameter preset and real-time monitoring, reducing operational complexity, and improving production consistency.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. In this application, an annular air curtain machine can be used to form an air curtain barrier at the opening of the glazing box to block the diffusion of harmful gases. The suction pipe is connected to an external air purification device through an external flange, thereby using the external air purification device to extract and purify the air under the suction hood.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] like Figure 1-4 As shown in the figure, this application discloses a Ru porcelain glazing device, including a glazing box 1. A ring-shaped air curtain machine 3 is fixedly installed on the side surface of the glazing box 1 by bolts. An L-shaped back plate 2 is welded to the back of the glazing box 1. A lead screw 7 is installed between the glazing box 1 and the L-shaped back plate 2. A drive motor 6 is installed at the end of the lead screw 7. A threaded sleeve 8 is threadedly connected to the surface of the lead screw 7. A glazing frame 9 is welded to the side surface of the threaded sleeve 8. An air suction hood 4 is welded to the front of the L-shaped back plate 2. An air suction pipe 5 is welded to the upper surface of the air suction hood 4. An external flange is installed at the end of the air suction pipe 5.

[0028] Glazing box 1 and annular air curtain machine 3: The side surface of glazing box 1 is machined with threaded holes. The annular air curtain machine 3 is fixed to the box body with bolts. The contact surface is equipped with a nitrile rubber sealing ring to ensure airtightness. The air curtain machine generates a high-speed airflow to form a 50mm wide air curtain barrier at the opening of the glazing box, controlling the VOCs diffusion range within 0.3m above the box body.

[0029] L-shaped back plate 2 and lead screw 7 transmission system: L-shaped back plate 2 is welded to the back of glazing box 1 to form a rigid structure. The weld is inspected to ensure that there are no cracks. The motor drives the lead screw 7 to rotate, which drives the threaded sleeve 8 and the glazing frame 9 to achieve lifting and lowering movement, so as to meet the glazing depth requirements of different types of vessels.

[0030] Suction hood 4 and suction pipe 5: Suction hood 4 is fully welded to the L-shaped back plate 2. After the suction pipe 5 is welded to the suction hood 4, it is connected to the external purification equipment through an external flange. When the external fan air volume is ≥2000m³ / h 3 At a rate of / h, a negative pressure of -30Pa is formed inside the suction hood 4, which, together with the air curtain, increases the efficiency of capturing harmful gases to over 95%.

[0031] The front of the L-shaped back panel 2 is welded with a recycling table 11, and a recycling drawer 13 is installed on the front of the recycling table 11. A porous ceramic plate 12 is placed inside the recycling table 11.

[0032] The recycling table 11, recycling drawer 13, and porous ceramic plate 12 are designed with the L-shaped back panel welded to the front, ensuring a strong connection. The recycling drawer 13 is installed on the front of the recycling table 11, connected to it via a slide rail. This rail connection allows the drawer 13 to be smoothly pulled out and pushed in, facilitating the cleaning of recycled glaze and trapped impurities. The porous ceramic plate 12 is placed inside the recycling table 11, with an embedded installation. This ensures the porous ceramic plate 12 is securely placed within the recycling table 11 and is easy to disassemble and replace. After glazing, the Ru porcelain drips into the recycling drawer 13 within the recycling table 11. The porous ceramic plate 12, with its unique porous structure, filters the glaze. The filtered glaze can be reused, reducing glaze waste and production costs, while also preventing impurities from contaminating the glaze and affecting the quality of the Ru porcelain glaze, thus improving the product qualification rate.

[0033] Corrugated tubes 10 are installed on the inner bottom surface of the glazing box 1 and the inner top surface of the L-shaped back plate 2. The corrugated tubes 10 are sleeved on the outer side of the lead screw 7, and the other ends of the two corrugated tubes 10 are fixedly connected to the threaded sleeve 8.

[0034] Corrugated pipe 10: Corrugated pipe 10 is installed on the inner bottom surface of the glazing box 1 and the inner top surface of the L-shaped back plate 2. One end of the corrugated pipe 10 is fixedly connected to the glazing box 1 or the L-shaped back plate 2, and the other end is tightly connected to the threaded sleeve 8. Corrugated pipe 10 serves as a protective component of the lead screw 7 transmission system, forming a tight fit with the lead screw 7, the threaded sleeve 8, and the glazing frame 9. When the drive motor 6 drives the lead screw 7 to rotate, and the threaded sleeve 8 moves up and down along the axis of the lead screw 7, the corrugated pipe 10 expands and contracts accordingly, always wrapping around the lead screw 7, preventing glaze, impurities, and harmful gases from contacting the lead screw 7, and protecting the lead screw 7 from glaze corrosion and impurity wear.

[0035] The glazing tank 1 is equipped with a stirring paddle 15, and the stirring paddle 15 is connected to a stirring motor 14 via a coupling. The stirring motor 14 is installed on the lower surface of the glazing tank 1.

[0036] Stirring motor 14 and stirring paddle 15: Stirring paddle 15 is installed inside the glazing tank 1. Stirring paddle 15 is connected to stirring motor 14 via a coupling. Stirring motor 14 is mounted on the lower surface of glazing tank 1. When stirring motor 14 is working, it transmits power to stirring paddle 15 through the coupling, causing stirring paddle 15 to stir the glaze within the glaze tank. The blades of stirring paddle 15 are designed with a special angle and shape to produce a strong stirring effect, ensuring uniform mixing of glaze components and preventing uneven glazing due to glaze sedimentation, thus improving the texture and process stability of Ru porcelain glaze. Simultaneously, uniform glaze helps improve the uniformity of the glaze layer during glazing, making the quality of Ru porcelain products more stable.

[0037] A resistance heater 16 is installed inside the glazing box 1, and a temperature sensor 17 is installed on the inner side of the glazing box 1.

[0038] Resistance heater 16 and temperature sensor 17: A resistance heater 16 is installed inside the glazing box 1. The resistance heater 16 is fixed to the inner wall of the glazing box 1 by a bracket. The bracket connection method ensures that the resistance heater 16 is stably installed and easy to adjust its installation position. After being powered on, the resistance heater 16 generates heat to heat the glaze in the glazing box to meet the melting temperature requirements of different glazes. A temperature sensor 17 is installed on the inner side of the glazing box 1. The temperature sensor 17 is fixed to the inner wall of the glazing box 1 by a threaded connection, which is convenient for installation and removal. The temperature sensor 17 monitors the glaze temperature in real time and feeds the temperature signal back to the integrated controller 18. The integrated controller 18 automatically controls the working state of the resistance heater 16 according to the preset temperature parameters, realizing precise control of the glaze temperature, avoiding defects such as cracking and bubbling on the glaze surface caused by temperature fluctuations, and ensuring the glazing quality of Ru porcelain.

[0039] An integrated controller 18 is fixed to the side surface of the glazing box 1 by bolts.

[0040] Integrated Controller 18: The integrated controller 18 is fixed to the side of the glazing box 1 by multiple bolts. Its internal PLC is connected to various sensors and actuators through shielded cables, integrating automated control of functions such as driving, stirring and heating. It supports parameter preset and real-time monitoring, reduces operation complexity and improves production consistency.

[0041] The operating principle of the Ru porcelain glazing device in this embodiment is as follows: After the Ru porcelain glazing device is started, the annular air curtain machine 3 and the suction hood 4 work together to construct a protective barrier against harmful gases. At the same time, the integrated controller 18 adjusts the screw 7 drive, glaze stirring, heating and other components according to preset parameters to realize automated glazing operation. The annular air curtain machine 3 starts first, forming an air curtain barrier at the opening of the glaze box with a wind speed of 15-20m / s, restricting the harmful gases generated by the volatilization of glaze inside the box. At the same time, the suction hood 4 is connected to an air purification device through an external flange, and under negative pressure, it draws away the harmful gases. The air curtain forms a lateral obstruction, and the suction hood 4 generates a longitudinal suction force. The two form a three-dimensional airflow field, which effectively reduces the concentration of harmful gases in the workshop and reduces the risk of respiratory exposure for workers. The drive motor 6 drives the screw 7 to rotate, and the threaded sleeve 8 moves smoothly up and down along the axis of the screw 7 due to the threaded drive with the screw 7. The glazing frame 9 welded to the side surface of the threaded sleeve 8 moves accordingly. When the glazing rack 9 descends to the preset depth inside the glaze tank, it pauses and fixes itself, allowing the Ru porcelain blank to complete the glazing process. After the set glazing time is reached, the glazing rack 9 rises and resets. During this process, the corrugated pipes 10 on the bottom surface of the glazing tank 1 and the top surface of the L-shaped back plate extend and retract synchronously with the threaded sleeve 8, tightly wrapping the screw 7 to prevent glaze splashing and harmful gases from corroding the screw 7, ensuring stable operation of the screw 7 transmission system, and extending the service life of the equipment. The stirring motor 14 drives the stirring paddle 15 through the coupling, rotating at a specific speed inside the glaze tank to continuously stir the glaze, preventing glaze components from settling, ensuring uniform glaze, and laying the foundation for high-quality glazing. The resistance heater 16 operates based on the real-time temperature data of the glaze monitored by the temperature sensor 17. When the temperature is lower than the preset value, it automatically starts heating; after reaching the set temperature, it stops heating, precisely controlling the glaze temperature within a suitable range to meet the melting characteristics requirements of different glazes and reduce glaze surface defects caused by temperature fluctuations. After glazing, the Ru porcelain is placed on the porous ceramic plate 12 at the recycling platform 11. The glaze is filtered through the porous ceramic plate 12 inside the recycling platform 11, trapping impurities such as body fragments and dust. The filtered glaze flows into the recycling drawer 13 for storage. Staff regularly clean the recycling drawer 13, achieving efficient recycling and reuse of the glaze, significantly improving the glaze recovery rate and reducing production costs.
