It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0032] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0033] like Figure 1 and Figure 2As shown, the glass kiln disclosed in the first embodiment of the present application includes: a kiln assembly 10 and a guide assembly 20, the kiln assembly 10 includes a crown structure 11 and a kiln structure 12, the crown structure 11 and the kiln structure 12 are arranged correspondingly, glass liquid is arranged in the kiln structure 12, the crown structure 11 has a through hole 111, the guide assembly 20 includes a guide pipe structure 21, the guide pipe structure 21 is movably arranged in the through hole 111, the first end of the guide pipe structure 21 is located on the side of the crown structure 11 away from the kiln structure 12, the second end of the guide pipe structure 21 is located in the kiln structure 12, the inner diameter of the guide pipe structure 21 is larger than the size of the to-be-putted object, and the second end of the guide pipe structure 21 has a putting state below the glass liquid level and a to-be-putted state above the glass liquid level.

[0034] The technical solution of the first embodiment is applied, and a guide assembly 20 is provided on the kiln assembly 10 for melting glass liquid, and the length of the guide assembly 20 extending into the kiln assembly 10 is adjusted so that the second end of the guide pipe structure 21 is located below the surface of the glass liquid, and the object to be put into the guide pipe structure 21 from the first end of the guide pipe structure 21, and the object to be put falls into the glass liquid along the guide pipe structure 21 under the action of gravity, and the putting is completed. The object flows with the glass liquid to the subsequent process and remains in the glass after the glass is cooled and formed. When it is necessary to adjust the parameters of the glass production process, the staff first adjusts the parameters, and after the parameter adjustment is completed, the object to be put is put into the glass liquid using the above operation. At this time, the glass produced after the glass with the object inside the product area is all glass products after the parameters are adjusted. The technical solution of the first embodiment effectively solves the problem in the prior art that the change of glass kiln parameters in the glass production process cannot accurately correspond to the product quality.

[0035] like Figure 1 and Figure 2As shown, in the technical solution of the first embodiment, the guide assembly 20 further includes a limiting structure 22, the limiting structure 22 is connected to the guide pipe structure 21, the limiting structure 22 is located on the side of the crown structure 11 away from the kiln structure 12, and the projection area of ​​the limiting structure 22 in the vertical direction is larger than the projection area of ​​the through hole 111 in the vertical direction. Since the projection area of ​​the limiting structure 22 in the vertical direction is larger than the projection area of ​​the through hole 111 in the vertical direction, the limiting structure 22 will not enter the interior of the kiln assembly 10 from the through hole 111. There is a predetermined distance between the limiting structure 22 and the first end of the guide pipe structure 21. Since the guide pipe structure 21 is connected to the limiting structure 22, the first end of the guide pipe structure 21 will not enter the interior of the kiln assembly 10 from the through hole 111. The setting of the limiting structure 22 prevents the entire guide pipe structure 21 from falling into the glass liquid in the kiln assembly 10, resulting in contamination of the glass liquid. The distance between the limiting structure 22 and the first end of the guide pipe structure 21 is 8 cm to 15 cm. When the limiting structure 22 abuts against the crown structure 11, if the distance between the first end of the guide pipe structure 21 and the limiting structure 22 is less than 8 cm, the staff may be easily affected by the heat radiation from the kiln assembly 10 when placing the objects to be placed, causing burns; if the distance between the first end of the guide pipe structure 21 and the limiting structure 22 is greater than 15 cm, the length of the guide pipe structure 21 is too large, resulting in unnecessary waste of materials.

[0036] In the technical solution of the first embodiment, the object to be put is a zirconium dioxide sphere. The zirconium dioxide material has good high temperature resistance. It will not melt in the high temperature glass liquid and will not react chemically with the glass liquid. It can be completely retained inside the formed glass. The spherical shape is conducive to the drop of the object along the guide pipe structure 21 into the glass liquid. Usually, the glass product produced after the glass product with the zirconium dioxide sphere is taken for inspection, and the inspection data of the glass product is matched with the changed parameters to determine the influence of the parameter change on the glass product.

[0037] like Figure 1 and Figure 2 As shown, in the technical solution of Example 1, the guide pipe structure 21 is made of corundum material. First, the hardness of the corundum material is relatively large, which avoids the problem that when the zirconium dioxide spheres collide with the inner wall of the guide pipe structure 21 and cause the inner wall of the guide pipe structure 21 to rupture when the zirconium dioxide spheres are placed. Second, the melting point of the corundum material is relatively high, and the guide pipe structure 21 will not melt after being inserted into the high-temperature glass liquid, thereby avoiding the failure of the guide pipe structure 21 and the contamination of the glass liquid. Third, the corundum material has good corrosion resistance, will not react with the glass liquid, and has a long service life. Figure 1 and Figure 2As shown, in the technical solution of the first embodiment, the kiln structure 12 includes an outlet 121, and the second end of the guide assembly 20 has a predetermined distance from the outlet 121 in parallel with the flow direction of the glass liquid. After the zirconium dioxide spheres are put into the glass liquid through the guide assembly 20, the zirconium dioxide spheres flow into the subsequent process from the outlet 121 with the glass liquid, and are finally retained in the finished glass. The guide assembly 20 is arranged at the front end of the glass liquid outflow, ensuring that when the subsequent process changes, the zirconium dioxide spheres can be put in in time to mark the glass, so as to correspond the changed parameters to the corresponding glass products.

[0038] like Figure 1 and Figure 2 As shown, in the technical solution of the first embodiment, in parallel to the flow direction of the glass liquid, the distance between the second end of the guide assembly 20 and the outlet 121 is 5 cm to 10 cm. When the distance between the second end of the guide assembly 20 and the outlet 121 is greater than 10 cm, the glass liquid between the second end of the guide pipe structure 21 and the outlet 121 is also the glass liquid put into production after the parameters are changed. When the product is finally produced, the glass products produced by this part of the glass liquid are produced before the glass products with the injection, and then the glass products produced after the glass products with the injection are taken for inspection, which will lead to a long waiting time for the production of the product to be inspected and low inspection efficiency; if the temperature of the glass liquid is low at this time, the viscosity of the glass liquid is high, because the height of the second end of the guide pipe structure 21 in the vertical direction is lower than the glass liquid surface, the surface of the glass liquid flowing through the guide pipe structure 21 will produce ripples. When the distance between the second section of the guide assembly 20 and the outlet 121 is less than 5 cm, the ripples cannot flow into the subsequent process after automatic leveling, affecting the surface quality of the glass product.

[0039] like Figure 1 and Figure 2 As shown, in the technical solution of the first embodiment, the glass kiln also includes a heat preservation structure 13, and the heat preservation structure 13 is connected to the crown structure 11. The setting of the heat preservation structure 13 avoids the heat loss inside the glass kiln, which causes the temperature difference between the glass liquid and the set temperature of the kiln structure 12 to be too large. The heat preservation structure 13 includes a heat preservation part, a heat insulating part and a support part. The heat insulating part includes a plurality of insulation bricks stacked together. The heat preservation part is connected to the insulation bricks and is located on the side of the insulation bricks away from the guide assembly 20. The support part is fixed on the frame. The heat insulating part is connected to the heat preservation part and the support part. The two are located on the side of the support part away from the kiln structure 12. The support part is fixed on the frame. There is a predetermined gap between the support part and the kiln structure 12 to prevent the kiln structure 12 from being subjected to a large pressure from the heat preservation structure 13.

[0040] like Figure 3As shown, the difference between the technical solution of the second embodiment and the technical solution of the first embodiment is that the guide assembly 20 also includes a vertical drive structure 23, the vertical drive structure 23 is located between the crown structure 11 and the limit structure 22, the vertical drive structure 23 is connected to the crown structure 11, and the output end of the vertical drive structure 23 is connected to the limit structure 22. The vertical drive structure 23 is set to provide a driving force in the vertical direction for the limit structure 22, change the height of the limit structure 22 in the vertical direction, and then change the height of the second end of the guide pipeline structure 21 in the vertical direction. The setting of the vertical drive structure 23 is convenient for controlling the height of the second end of the guide pipeline structure 21 in the vertical direction to be lower or higher than the glass liquid surface. When it is not necessary to put in the zirconium dioxide sphere, the vertical drive structure 23 provides an upward driving force to make the second end of the guide pipeline structure 21 away from the glass liquid surface, so as to avoid the problem of reduced service life due to the long-term immersion of the guide pipeline structure 21 in the glass liquid.

[0041] like Figure 4 and Figure 5 As shown, the difference between the technical solution of the third embodiment and the technical solution of the first embodiment is that the guide assembly 20 further includes an elastic structure 24 and a force structure 25, the elastic structure 24 is connected to the inner wall of the guide pipeline structure 21, the force structure 25 is arranged corresponding to the first end of the guide pipeline structure 21, and a plurality of objects to be placed are arranged in the guide pipeline structure 21 and are located between the elastic structure 24 and the force structure 25. The force structure 25 provides a downward force for the zirconium dioxide sphere to be placed, and the elastic structure 24 is elastically deformed by the downward force, and the zirconium dioxide sphere passes through the elastic structure 24 and falls into the glass liquid along the guide pipeline structure 21. When the external force applied by the force structure 25 to the zirconium dioxide sphere cannot overcome the elastic force of the elastic structure 24, the zirconium dioxide sphere is blocked on the side of the elastic structure 24 away from the second end of the guide pipeline structure 21 under the action of the elastic structure 24, and cannot fall into the glass liquid. By controlling the force size and time of the force structure 25, the number of zirconium dioxide spheres falling into the glass liquid can be controlled.

[0042] like Figure 4 and Figure 5As shown, in the technical solution of embodiment three, the elastic structure 24 includes a plurality of elastic parts 241, and the plurality of elastic parts 241 are evenly distributed along the inner wall of the guide pipe structure 21, and there is a predetermined gap between adjacent elastic parts 241. The cross-sectional shape of the elastic part 241 in the horizontal direction is fan-shaped. The height of the elastic part 241 in the vertical direction is the same everywhere. The diameter of the elastic part 241 is smaller than the inner diameter of the guide pipe structure 21, and the arc surface of the elastic part 241 is arranged in affixed with the inner wall of the guide pipe structure 21, and the gap between adjacent elastic parts 241 is smaller than the diameter of the zirconium dioxide sphere. When the force-applying part 251 applies an external force to the zirconium dioxide sphere, the elastic part 241 undergoes elastic deformation, and the plurality of elastic parts 241 move downward away from the inner wall of the guide pipe structure 21 and away from each other, and the zirconium dioxide sphere passes through between the plurality of elastic parts 241 and falls into the glass liquid along the guide pipe structure 21.

[0043] like Figure 4 and Figure 5 As shown, in the technical solution of the third embodiment, the force-applying structure 25 includes a force-applying part 251, and the force-applying part 251 has a force-applying state close to the object to be delivered and a waiting state for force-applying state away from the object to be delivered. The projection of the force-applying part 251 in the vertical direction is located within the projection of the inner wall of the guide pipe structure 21 in the vertical direction. The force-applying structure 25 also includes a cylinder, and the output end of the cylinder is connected to the force-applying part 251 to provide a downward external force for the zirconium dioxide sphere. The glass furnace also includes a control and monitoring component. A certain number of zirconium dioxide balls are arranged in the guide pipe structure 21. At this time, the deformation of the elastic structure 24 under the gravity of the zirconium dioxide balls is not enough to allow the zirconium dioxide balls to pass through. When the control and monitoring component detects that a parameter in the glass production line has changed, it sends a signal to the force-applying structure 25, and the cylinder pushes the force-applying part 251 to move in the direction close to the zirconium dioxide ball. The force-applying part 251 provides external force for the zirconium dioxide ball. The elastic part 241 is subjected to an increased external force, and the elastic deformation increases, so that the zirconium dioxide ball can pass through. The number of zirconium dioxide balls put in can be controlled by controlling the stroke size of the cylinder. Usually, a single parameter change corresponds to one zirconium dioxide ball. The control and monitoring component records the number of parameter changes. When the number of parameter changes reaches the number of zirconium dioxide balls preset in the guide pipe structure 21, it is necessary to reset the zirconium dioxide balls in the guide pipe structure 21 for subsequent placement.

[0044] From the above, it can be known that a through hole 111 is opened at the crown of the glass kiln (crown structure 11), and its size is slightly larger than the corundum tube (guide pipe structure 21). The length of the corundum tube is not greater than the height of the crown of the glass kiln, and a limiter (limiting structure 22) is set on the top, so that the ZrO2 ball dropped from the top can freely fall to the flow hole (exit 121) of the glass kiln pool wall (kiln structure 12). After the ZrO2 tracer ball is dropped into the flow hole through the corundum tube, it is retained in the product after passing through the channel, molding and other sections with the flowing glass liquid, so that the optimization adjustment of the process parameters accurately corresponds to the product quality, and the process optimization efficiency is improved. A flow hole connected to the channel part is set at the lower part of the glass kiln pool wall to send the molten glass liquid into the channel for the next step. There is a gap between the glass kiln hook brick (support part) and the glass kiln pool wall, so that the glass kiln pool wall brick does not bear the pressure from the upper brick structure (insulation part). The rear wall of the glass kiln (insulation part) is set above the glass kiln hook brick to play the role of kiln insulation. A limiter is set above it to accurately drop the ZrO2 tracer ball into the flow hole. Its ZrO2 content should be greater than 95%, which can withstand the erosion of high-temperature glass liquid. The diameter is smaller than the thickness of the glass and does not cause damage to the equipment. After using the glass kiln ZrO2 tracer ball and the brick structure, the parameter optimization can be accurately matched with the product quality, and the kiln process optimization efficiency can be improved.
