Description

Technical Field

[0001] The present application relates to the technical field of glass production, and particularly relates to a glass furnace and a method for cleaning tin ash. Background Art

[0002] Float glass is widely used in the glass production process due to its advantages such as a flat surface, high transparency, and high production efficiency.

[0003] In the production of float ultra-thin glass, at the outlet end of the tin bath, since the outlet height is higher than the liquid level height of the tin bath inside the tin bath, there is a triangular-shaped gap with a triangular cross-section under the glass near the outlet, which is called the triangular area.

[0004] In the prior art, there is tin ash on the surface of the tin bath. The tin ash moves with the glass to the outlet of the tin bath. The triangular area at the outlet of the tin bath is prone to accumulating tin ash. Due to the small space in the triangular area, when the glass size is large, it is difficult to clean the tin ash in the middle area of the triangular area. When a large amount of tin ash accumulates, it is easy to be carried out of the tin bath by the glass plate and cause damage to the lower surface of the glass under the extrusion of the traction roller, such as CN222524395U.

[0010] In some embodiments, the transition structure has a receiving groove, and part of the cleaning component is located in the receiving groove. The height of the cleaning component in the vertical direction is lower than the height of the end of the transition structure close to the traction component in the vertical direction.

[0011] In some embodiments, the cleaning component further includes a driving motor structure. The spiral blade structure is connected to the output end of the driving motor structure, and the driving motor structure is located outside the tin bath component.

It should also be understood that terms defined in a general dictionary, for example, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.

[0035] Techniques, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and devices should be regarded as part of the specification.

[0036] Such as Figures 1 to 5As shown in the figure, the tin bath assembly 10, the traction assembly 20, and the cleaning assembly 30 disclosed in the embodiments of the present application. The tin bath assembly 10 has a tin bath outlet 11. The height of the upper edge of the traction assembly 20 in the vertical direction is higher than the height of the lower edge of the tin bath outlet 11 in the vertical direction. The cleaning assembly 30 includes a spiral blade structure 31. The spiral blade structure 31 is rotatably connected to the tin bath assembly 10 and is disposed inside the tin bath assembly 10.

[0037] Applying the technical solution of the embodiments of the present application, during the production process, the glass floats on the tin liquid inside the tin bath assembly 10 and leaves the tin bath assembly 10 from the tin bath outlet 11 under the action of the traction assembly 20. During this process, the tin ash moves with the glass to the tin bath outlet 11 and remains in the triangular area between the glass and the tin liquid. As the glass is continuously produced, the tin ash accumulates at the triangular area. When there is more tin ash at the triangular area, rotate the spiral blade structure 31. Under the action of the spiral blade structure 31, the tin ash moves along the direction close to the end of the spiral blade structure 31, that is, close to the side wall direction of the tin bath assembly 10, so that the tin ash located in the middle of the triangular area moves to the edge of the glass, facilitating the centralized cleaning of the tin ash. The technical solution of this embodiment effectively solves the problem of difficult tin ash cleaning in the prior art during the production process of float glass.

[0038] As Figures 1 to 3 shown in the figure, in the technical solution of this embodiment, the spiral blade structure 31 includes a first spiral blade 311, a second spiral blade 312, and a rotating shaft 313. The first spiral blade 311 and the second spiral blade 312 are connected. The first spiral blade 311 and the second spiral blade 312 have opposite spiral directions. Both the first spiral blade 311 and the second spiral blade 312 are connected to the rotating shaft 313. The rotating shaft 313 is rotatably connected to the inner wall of the tin bath assembly 10. The parameters such as the diameter and pitch of the first spiral blade 311 and the second spiral blade 312 are the same, and the only difference is the rotation direction. The lengths of the first spiral blade 311 and the second spiral blade 312 are the same. The projection of the connection part of the two in the vertical direction coincides with the midline of the glass in the width direction. The total length of the first spiral blade 311 and the second spiral blade 312 is greater than the width of the glass. The first spiral blade 311 and the second spiral blade 312 rotate synchronously with the rotating shaft 313, so that the tin ash in the triangular area under the glass is respectively brought to both sides of the glass and leaves directly below the glass, facilitating cleaning and with higher efficiency. The first spiral blade 311 and the second spiral blade 312 are made of high-purity graphite material, the rotating shaft 313 is made of high-purity quartz ceramic material, and the spiral blade structure 31 further includes a bearing seat connected to the tin bath assembly 10. The bearing seat is made of a high-purity graphite ring. The above materials have stable chemical properties, are not prone to chemical reactions with high-temperature tin liquid, are corrosion-resistant, and have a long service life.

[0039] AsFigures 1 to 3 As shown, in the technical solution of this embodiment, the tin bath assembly 10 includes a transition structure 12. The height of one end of the transition structure 12 close to the traction assembly 20 in the vertical direction is higher than the height of the other end of the transition structure 12 away from the traction assembly 20 in the vertical direction. The transition structure 12 is used to connect the tin bath outlet 11 and the bottom of the tin bath assembly 10 in a transitional manner, providing support for the inclined glass, and avoiding breakage at the tin bath outlet due to the downward bending of the glass caused by its thinness and the influence of the high-temperature environment, which may interrupt the continuous production of the glass plate and reduce the production efficiency and product qualification rate.

[0040] As Figures 1 to 3 Shown, in the technical solution of this embodiment, the transition structure 12 has a receiving groove 121. Part of the cleaning assembly 30 is located in the receiving groove 121. The height of the cleaning assembly 30 in the vertical direction is lower than the height of the end of the transition structure 12 close to the traction assembly 20 in the vertical direction. The provision of the receiving groove 121 is for accommodating the spiral blade structure 31. By installing the spiral blade structure 31 in the receiving groove 121, the layout height of the receiving groove 121 is reduced, and interference between the spiral blade structure 31 and the upper glass is avoided.

[0041] As Figures 1 to 3 Shown, in the technical solution of this embodiment, the cleaning assembly 30 further includes a driving motor structure. The spiral blade structure 31 is connected to the output end of the driving motor structure, and the driving motor structure is located outside the tin bath assembly 10. The driving motor structure is used to drive the spiral blade structure 31 to rotate, and it is convenient to adjust the rotation speed and rotation time. The driving motor structure is arranged outside the tin bath assembly 10 to avoid the influence of the high-temperature environment inside the tin bath assembly 10 on the service life of the driving motor structure, and at the same time, it is convenient for the staff to operate. In other embodiments, a handwheel can also be used to replace the driving motor structure, and the staff can rotate the handwheel to control the spiral blade structure 31.

[0042] As Figure 1 and Figure 4 Shown, in the technical solution of this embodiment, the tin bath assembly 10 includes a side wall structure 13 and an ear bath structure 14. The ear bath structure 14 is connected to the side wall structure 13, and the transition structure 12 is connected to the side wall structure 13. The tin liquid with more tin ash flows into the ear bath structure 14 for recovery under the action of the spiral blade structure 31, avoiding the re-mixing of tin ash into the working tin liquid.

[0043] As Figure 1 and Figure 4As shown, in the technical solution of this embodiment, the distance between the ear pond structure 14 and the spiral blade structure 31 is 550 mm to 700 mm. The ear pond structure 14 is located upstream of the spiral blade structure 31. As the spiral blade structure 31 rotates, it drives the tin liquid and tin ash at this location to move towards the end of the spiral blade structure 31 until it reaches the side wall structure 13. At this time, the tin liquid containing a large amount of tin ash is located on both sides of the glass. Under the continuous movement of the glass, back convection occurs between the tin ash and the tin liquid, and the flow direction of the tin liquid containing tin ash is opposite to the movement direction of the glass, that is, it moves towards the ear pond structure 14. Along the movement direction of the glass, the distance between the ear pond structure 14 and the spiral blade structure 31 is 550 mm to 700 mm. When the distance between the ear pond structure 14 and the spiral blade structure 31 is less than 550 mm, the refluxed tin ash is likely to move upstream of the ear pond structure 14, which is not conducive to tin ash recovery; when the distance between the ear pond structure 14 and the spiral blade structure 31 is greater than 700 mm, the refluxed tin ash cannot reach the ear pond structure 14, which is also not conducive to recovery.

[0044] As Figure 1 , Figure 4 and Figure 5 shown, in the technical solution of this embodiment, the cleaning assembly 30 further includes a cleaning structure 32, and the cleaning structure 32 is arranged inside the ear pond structure 14. The cleaning structure 32 is used to bring the tin liquid containing a large amount of tin ash into the ear pond for recycling treatment of the tin liquid. The cleaning structure 32 includes a cylinder, a connecting rod, and a scraper. The first end of the connecting rod is connected to the cylinder, and the second end of the connecting rod is connected to the scraper. Under the action of the linear actuator, the scraper scrapes the tin liquid with more tin ash on the upper layer into the ear pond for cleaning and recycling. There is an inclined surface at the connection between the ear pond structure 14 and the side wall structure 13. The cylinder is rotatably connected to the ear pond structure 14. The cylinder drives the connecting rod and the scraper to move. When cleaning the tin ash, the scraper extends from above the liquid level of the tin liquid, rotates the cylinder to lower the scraper to contact the tin liquid, and the cylinder drives the scraper to move towards the cylinder direction to guide the tin ash onto the inclined surface and then into the ear pond. The above structure avoids the problem of a large amount of tin liquid entering the ear pond, resulting in waste of tin liquid.

[0045] As Figure 1 and Figure 2As shown, in the technical solution of this embodiment, the tin bath assembly 10 further includes an observation window structure. The observation window structure is located on the sidewall structure 13, and the height of the observation window structure in the vertical direction is higher than the height of the cleaning assembly 30 in the vertical direction. The setting of the observation window structure facilitates the staff to observe the triangular area under the glass plate. When there is a large accumulation of tin ash, the staff needs to operate to rotate the spiral blade structure 31 to clean the tin ash in the triangular area in time, avoiding excessive accumulation of tin ash being carried out of the tin bath assembly 10 by the glass plate. After the tin ash is reduced, the spiral blade structure 31 needs to stop rotating to avoid having a greater impact on the flow of tin liquid, affecting the product quality, and saving energy.

[0046] According to another aspect of the present application, a tin ash cleaning method is also provided. The tin ash cleaning method uses the above glass furnace, and the tin ash cleaning method includes the following steps:

[0047] Observe the tin ash content at the tin bath outlet 11;

[0048] Rotate the spiral blade structure 31;

[0049] Clean the tin ash.

[0050] The staff observes the inside of the tin bath assembly 10 through the observation port structure. When the tin ash content in the triangular area is relatively large, it is necessary to control the rotation of the spiral blade structure 31 to move the tin ash in the triangular area to both sides of the glass. Then, the tin ash convects back with the tin liquid and moves to the vicinity of the ear tank, and is carried into the ear tank under the action of the cleaning structure 32 to achieve tin ash cleaning. When the tin ash content is relatively small, in order to reduce the impact of tin liquid flow on the quality of glass products, it is not necessary to control the rotation of the spiral blade structure 31, and energy is saved at the same time.

[0051] To verify the specific cleaning effect,

[0052] The following experiment is adopted: Three different spiral blade structures 31 are selected, and the cleaning effects under different rotation speed conditions are compared respectively. Table 1 shows the parameters of the three groups of spiral blade structures 31, Table 2 shows the quality of glass products of the first group of spiral blade structures 31 under different rotation speed conditions, Table 3 shows the quality of glass products of the second group of spiral blade structures 31 under different rotation speed conditions, and Table 4 shows the quality of glass products of the third group of spiral blade structures 31 under different rotation speed conditions.

[0053] Table 1

[0056]

[0057] Table 3

[0058]

[0059]

[0060] Table 4

[0061]

[0062] From the above experimental data, it can be seen that after using the spiral blade structure 31, the tin ash adhered to the glass plate is reduced, and due to the reduction of tin ash, the abrasions generated on the glass plate under the extrusion of the traction assembly 20 are reduced. X1 is the number of tin-stained areas on the entire plate without using the spiral blade structure 31, and X2 is the number of tin-stained areas on the entire plate after using the spiral blade structure 31. The reduction rate of tin ash on the glass surface can be calculated by (X1 - X2) / X1. Table 5 shows the reduction rates of tin ash on the glass surface corresponding to three groups of spiral blade structures 31 under different rotational speeds.

[0063] Table 5

[0064] Rotational speed (r / min) First group Second group Third group 5 72.27％ 88.93％ 75.13％ 10 64.74％ 46.96％ 50.38％ 15 62.94％ 69.71％ 65.93％ 20 82.19％ 90.59％ 77.11％ 25 38.09％ 38.88％ 34.08％

[0065] By comparing the experimental data in Table 5, the cleaning effect of the spiral blade structure 31 in the second group at a rotational speed of 10 r / min is significantly lower than that at rotational speeds of 5 r / min and 15 r / min and is significantly lower than that of other groups. Therefore, this group of data can be considered as obvious errors. After excluding this group of data, the cleaning effect of the second group is significantly better than that of other groups. Therefore, it is preferred to use the spiral blade structure 31 of the second group. When the rotational speed is 25 r / min, the reduction rate of tin ash on the glass surface is significantly lower. After analysis, it is found that when the rotational speed is relatively fast, the phenomenon that the tin liquid and tin ash adhere to the lower surface of the glass under the action of centrifugal force is obvious, and when the rotational speed is relatively fast, the liquid level of the tin liquid fluctuates greatly, which is likely to cause instability in the production process. During the cleaning process, it is necessary to control the rotational speed of the spiral blade structure 31 not to exceed 20 r / min, and usually 10 r / min to 20 r / min is selected.

[0066] As described above, this application is installed in the semi-circular groove (accommodating groove 121) of the bottom brick (transition structure 12) at the outlet of the tin bath, aiming to bring the tin ash in the triangular area to both sides of the outlet (tin bath outlet 11) by rotating the spiral structure (spiral blade structure 31) for cleaning. It is necessary to add a semi-circular groove with a diameter of 70 mm, a high-purity graphite spiral device with a diameter of 55 mm, use high-purity quartz ceramics with a diameter of 30 mm as the rotating shaft of the spiral structure, and use a high-purity graphite ring with a diameter of 30 mm as the bearing seat. This structure consists of a high-purity graphite spiral and high-purity quartz ceramics, and uses a high-purity graphite ring as the bearing. The high-purity graphite spiral device is fixed on the side bricks through a high-purity quartz ceramic shaft (rotating shaft 313). The quartz ceramic shaft head is connected to the rotating device, and the rotating device is designed with two modes: manual and automatic. When there is a large amount of tin ash accumulated in the triangular area, rotate this device to bring the tin ash out of the triangular area through the spiral structure. This device can be installed during the initial installation or can be retrofitted during the cold repair of the tin bath. This graphite device is immersed in the tin liquid, is not easily oxidized, does not contact the glass plate, nor does it contact the bottom brick, and only acts on the tin liquid. By rotating the spiral structure, it drives the tin liquid and thus drives the tin ash to bring the tin ash out of the triangular area. This device can rotate freely. When not in use, this device can remain stationary. When needed, this device can be rotated manually or automatically to make the tin ash in the triangular area flow to both sides, and then be taken to the ear pond (ear pond structure 14) by the slag skimmer (cleaning structure 32) for cleaning.
