Abstract
Description
A sealing connection structure between a float glass tin bath and a tin bath edge seal. Technical Field
[0001] This invention belongs to the field of float glass production technology, specifically relating to a sealing connection structure between the tin bath and the edge seal of the float glass tin bath. Background Technology
[0002] The tin bath is one of the three major thermal equipment in float glass production. The edge seal of the tin bath plays a crucial role in sealing and heat preservation of the tin bath. Therefore, the sealing performance between the edge seal and the tin bath will affect the quality and cost of the produced glass sheets.
[0003] In existing technology, after the tin bath edge seal is installed at the corresponding position in the tin bath, the connection between the tin bath edge seal and the tin bath is sealed by filling with sealant. However, this sealing method has the problems of large amount of sealant used and large amount of manual labor. Moreover, the tin bath will expand during the heating process, and the expansion of the tin bath steel structure will cause the sealant to crack, which will require multiple sealant repairs, which will also lead to a large amount of manual labor. In addition, the cracking of the sealant before the sealant is repaired will affect the atmosphere in the tin bath, thereby affecting the quality of the produced glass plate. Summary of the Invention
[0004] In view of the above-mentioned defects of the prior art, the present invention provides a sealing connection structure between the tin bath and the tin bath edge seal of float glass, which can reduce the amount of sealing putty used and the amount of manual labor, improve the sealing performance of the tin bath, and reduce defects in the produced glass sheets.
[0005] The technical solution adopted by this invention to solve its technical problem is:
[0006] A sealing connection structure between a float glass tin bath and a tin bath edge seal includes a top cover steel structure side plate, a bottom steel structure bottom shell steel plate, and a tin bath edge seal. The lower outer part of the top cover steel structure side plate is used to install a first angle steel, and the lower inner part is used to install a second angle steel. The upper part of the second angle steel is used to install a breast wall brick. The upper outer part of the bottom steel structure bottom shell steel plate is used to install a third angle steel, and the inner part is used to install a tin bath bottom brick. A certain gap is left between the breast wall brick and the tin bath bottom brick to form an installation space for installing the tin bath edge seal. The tin bath edge seal includes an outer edge portion located outside the tin bath and an inner edge seal body located within the installation space. The outer edge portion of the edge seal is inserted and fitted with the first angle steel or the third angle steel to achieve a sealing connection between the tin bath and the tin bath edge seal.
[0007] Furthermore, the outer perimeter of the edge seal has an upper insertion slot reserved at the position corresponding to the first angle steel, and the first angle steel is inserted into the upper insertion slot.
[0008] Furthermore, the first angle steel includes a first angle steel horizontal plate and a first angle steel vertical plate, and the upper insertion port includes an upper insertion port horizontal segment and an upper insertion port vertical segment. The first angle steel horizontal plate is inserted into the upper insertion port horizontal segment, and the first angle steel vertical plate is inserted into the upper insertion port vertical segment.
[0009] Furthermore, a certain gap is left between the first angle steel vertical plate and the corresponding side of the outer perimeter of the upper insertion vertical segment, and the gap is filled with sealing putty.
[0010] Furthermore, the gap between the top surface of the edge seal body and the bottom surface of the breast wall brick was not filled with sealant.
[0011] Furthermore, the outer perimeter of the edge seal has a pre-reserved lower insertion port at the position corresponding to the third angle steel, and the third angle steel is inserted into the lower insertion port.
[0012] Furthermore, the third angle steel includes a horizontal plate and a vertical plate, and the lower insertion port includes a horizontal segment and a vertical segment. The horizontal plate of the third angle steel is inserted into the horizontal segment of the lower insertion port, and the vertical plate of the third angle steel is inserted into the vertical segment of the lower insertion port.
[0013] Furthermore, the third angle steel vertical plate leaves a certain gap between the vertical segment of the lower insertion port and the corresponding side of the outer perimeter of the edge seal, and fills it with sealing putty.
[0014] Furthermore, the gap between the bottom surface of the edge seal body and the top surface of the tin bath bottom brick was not filled with sealant.
[0015] Furthermore, the top surface of the bottom brick of the tin bath is flush with the top surface of the bottom steel plate of the bottom steel structure of the bath.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0017] The sealing connection structure between the float glass tin bath and the tin bath edge seal in this invention includes a top cover steel structure side plate, a bottom steel structure bottom shell steel plate, and a tin bath edge seal. The lower outer part of the top cover steel structure side plate is used to install a first angle steel and the lower inner part is used to install a second angle steel. The upper part of the second angle steel is used to install a breast wall brick. The upper outer part of the bottom steel structure bottom shell steel plate is used to install a third angle steel and the inner part is used to install a tin bath bottom brick. A certain gap is left between the breast wall brick and the tin bath bottom brick to form an installation space for installing the tin bath edge seal. The tin bath edge seal includes an outer edge portion located outside the tin bath and an inner edge seal body located within the installation space. The outer edge portion of the edge seal is inserted and fitted with the first angle steel or the third angle steel to achieve a sealing connection between the tin bath and the tin bath edge seal. This sealing connection between the tin bath and the tin bath edge seal is achieved through the interlocking fit between the outer perimeter of the tin bath edge seal and the first angle steel installed on the lower outer side of the top cover steel structure side plate, or through the interlocking fit between the outer perimeter of the tin bath edge seal and the first angle steel installed on the upper outer side of the bottom steel plate of the tin bath bottom shell. This improves the sealing performance of the tin bath, reduces the entry of unfavorable gases into the tin bath, thereby reducing defects in the produced glass sheets and saving energy. Furthermore, because the first angle steel is inserted at the fit gap between the outer perimeter of the tin bath edge seal and the top cover steel structure side plate, only a small amount of sealant needs to be applied to this gap. A third angle steel is inserted at the fit gap between the outer perimeter of the tin bath seal and the bottom steel plate of the tin bath bottom structure. This means that only a small amount of sealant needs to be applied to the fit gap between the outer perimeter of the tin bath seal and the bottom steel plate of the tin bath bottom structure. This reduces the amount of sealant used and the amount of manual labor. Because the amount of sealant used is reduced, the number of times sealant needs to be repaired due to sealant cracking caused by the thermal expansion of the tin bath steel structure is reduced. This, in turn, reduces the number of times sealant cracking affects the atmosphere inside the tin bath. Consequently, the sealing performance between the tin bath and the tin bath sealant, as well as the sealing performance of the tin bath, is improved. This also reduces defects in the produced glass sheets. The reduction in the number of sealant repairs also reduces the amount of manual labor.
[0018] In this invention, the outer periphery of the side seal has a pre-reserved upper insertion opening at the position corresponding to the first angle steel, and the first angle steel is inserted into the upper insertion opening; the first angle steel includes a first angle steel horizontal plate and a first angle steel vertical plate, the upper insertion opening includes an upper insertion opening horizontal segment and an upper insertion opening vertical segment, the first angle steel horizontal plate is inserted into the upper insertion opening horizontal segment, and the first angle steel vertical plate is inserted into the upper insertion opening vertical segment; a certain gap is left between the first angle steel vertical plate in the upper insertion opening vertical segment and the corresponding side of the outer periphery of the side seal and is filled with sealing putty. Since the first angle steel is installed on the lower outer side of the side plate of the top cover steel structure, and the second angle steel is installed on the lower inner side of the side plate of the top cover steel structure, the breast wall brick is installed on the second angle steel, and the breast wall brick is located between the horizontal and vertical steel plates of the second angle steel. Since the vertical plate of the first angle steel is filled with sealant in the gap between the vertical segment of the upper insertion on the outer perimeter of the side seal and the corresponding side of the outer perimeter of the side seal, and the side seal body of the tin bath is located in the installation space enclosed by the breast wall brick and the bottom brick of the tin bath, there is no need to fill the gap between the top surface of the side seal body and the bottom surface of the breast wall brick, thus further reducing the amount of sealant used.
[0019] In this invention, a lower insertion port is reserved at the position corresponding to the third angle steel on the outer periphery of the side seal, and the third angle steel is inserted into the lower insertion port; the third angle steel includes a horizontal plate and a vertical plate, and the lower insertion port includes a horizontal segment and a vertical segment. The horizontal plate is inserted into the horizontal segment, and the vertical plate is inserted into the vertical segment; a certain gap is left between the vertical plate and the corresponding side of the outer periphery of the side seal in the vertical segment of the lower insertion port, and the gap is filled with sealing putty. Since the third angle steel is installed on the upper outer side of the bottom steel plate of the bottom steel structure of the trough, and the bottom brick of the tin bath is installed on the inner side of the bottom steel plate of the bottom steel structure of the trough, and since the vertical section of the third angle steel vertical plate at the lower insertion point of the outer perimeter of the side seal is filled with sealant, and the side seal body of the tin bath is located in the installation space enclosed between the breast wall brick and the bottom brick of the tin bath, there is no need to fill the gap between the bottom surface of the side seal body and the top surface of the bottom brick of the tin bath with sealant, thus further reducing the amount of sealant used.

[0028] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.
[0029] In the description of this invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0031] As shown in Figures 1 and 4, a sealing connection structure between a float glass tin bath and a tin bath edge seal includes a top cover steel structure side plate 1, a bottom steel structure bottom shell steel plate 2, and a tin bath edge seal 3. The lower outer part of the top cover steel structure side plate 1 is used to install a first angle steel 4, and the lower inner part is used to install a second angle steel 5. The upper part of the second angle steel 5 is used to install a breast wall brick 6, wherein the breast wall brick 6 is located between the horizontal and vertical steel plates of the second angle steel 5. The upper outer part of the bottom steel structure bottom shell steel plate 2 is used to install a third angle steel 7, and the inner part is used to install a tin bath bottom brick 8. A certain gap is left between the breast wall brick 6 and the tin bath bottom brick 8 to form an installation space 9 for installing the tin bath edge seal 3 (see Figure 7). The tin bath edge seal 3 includes an outer edge seal portion 301 located outside the tin bath and an inner edge seal body 302 located within the installation space 9. The outer edge seal portion 301 is inserted and engaged with the first angle steel 4 or the third angle steel 7 to achieve a sealing connection between the tin bath and the tin bath edge seal 3.
[0032] This sealing connection between the tin bath and the tin bath edge seal 3 is achieved through the interlocking fit between the outer periphery 301 of the tin bath edge seal 3 and the first angle steel 4 installed on the lower outer side of the top cover steel structure side plate 1, or through the interlocking fit between the outer periphery 301 of the tin bath edge seal 3 and the first triangular steel 7 installed on the upper outer side of the bottom steel plate 2 of the bottom steel structure. This improves the sealing performance of the tin bath, reduces the entry of unfavorable gases into the tin bath, reduces defects in the produced glass sheets, and saves energy. Furthermore, because the first angle steel 4 is inserted at the fit gap between the outer periphery 301 of the tin bath edge seal 3 and the top cover steel structure side plate 1, only a small amount of sealant is needed at the fit gap between the outer periphery 301 of the tin bath edge seal 3 and the top cover steel structure side plate 1. A third angle steel 7 is inserted at the mating gap between the outer periphery 301 of the tin bath edge seal 3 and the bottom steel plate 2 of the tin bath bottom steel structure. This means that only a small amount of sealant needs to be applied to the mating gap between the outer periphery 301 of the tin bath edge seal 3 and the bottom steel plate 2 of the tin bath bottom steel structure. This reduces the amount of sealant used and the amount of manual labor. Because the amount of sealant used is reduced, the number of times sealant needs to be repaired due to cracking caused by the thermal expansion of the tin bath steel structure is reduced. This reduces the number of times sealant cracking affects the atmosphere inside the tin bath, thereby improving the sealing connection performance between the tin bath and the tin bath edge seal 3, as well as the sealing performance of the tin bath. It also reduces the defects of the produced glass plates. The reduction in the number of repairs also reduces the amount of manual labor.
[0033] In one embodiment,
[0034] The outer perimeter 301 of the edge seal has an upper insertion port reserved at the position corresponding to the first angle steel 4, and the first angle steel 4 is inserted into the upper insertion port.
[0035] The first angle steel 4 includes a first angle steel horizontal plate 401 and a first angle steel vertical plate 402, as shown in Figures 1 and 2. The upper insertion port includes an upper insertion port horizontal segment 301011 and an upper insertion port vertical segment 301012, as shown in Figures 1-3. The first angle steel horizontal plate 401 is inserted into the upper insertion port horizontal segment 301011, and the first angle steel vertical plate 402 is inserted into the upper insertion port vertical segment 301012, as shown in Figures 1 and 2.
[0036] Among them, the first angle steel vertical plate 402 has a certain gap between the upper insertion vertical segment 301012 and the corresponding side of the outer perimeter of the side seal 301 and is filled with sealing putty.
[0037] In particular, the gap between the top surface of the side seal body 302 and the bottom surface of the breast wall brick 6 was not filled with sealant.
[0038] Since the first angle steel 4 is installed on the lower outer side of the side plate 1 of the top cover steel structure, and the second angle steel 5 is installed on the lower inner side of the side plate 1 of the top cover steel structure, the breast wall brick 6 is installed on the second angle steel 5, and the breast wall brick 6 is located between the horizontal steel plate and the vertical steel plate of the second angle steel 5, and since the gap between the vertical plate 402 of the first angle steel and the corresponding side of the outer perimeter of the side seal 301 is filled with sealant, and the side seal body 302 of the tin bath side seal 3 is located in the installation space 9 enclosed between the breast wall brick 6 and the bottom brick 8 of the tin bath, there is no need to fill the gap between the top surface of the side seal body 302 and the bottom surface of the breast wall brick 6, thus further reducing the amount of sealant used.
[0039] In one embodiment,
[0040] The outer perimeter of the edge seal 301 has a lower insertion slot reserved at the position corresponding to the third angle steel 7, and the third angle steel 7 is inserted into the lower insertion slot.
[0041] The third angle steel 7 includes a horizontal third angle steel plate 701 and a vertical third angle steel plate 702, as shown in Figures 4 and 5. The lower insertion port includes a horizontal lower insertion port segment 301021 and a vertical lower insertion port segment 301022, as shown in Figures 4-6. The horizontal third angle steel plate 701 is inserted into the horizontal lower insertion port segment 301021, and the vertical third angle steel plate 702 is inserted into the vertical lower insertion port segment 301022, as shown in Figures 4 and 5.
[0042] Among them, the third angle steel vertical plate 702 has a certain gap between the lower insertion vertical segment 301022 and the corresponding side of the outer perimeter of the side seal 301 and is filled with sealing putty.
[0043] In particular, the gap between the bottom surface of the side seal body 302 and the top surface of the tin bath bottom brick 8 was not filled with sealant.
[0044] Since the third angle steel 7 is installed on the upper outer side of the bottom steel plate 2 of the bottom steel structure of the trough, and the bottom brick 8 of the tin bath is installed on the inner side of the bottom steel plate 2 of the bottom steel structure of the trough, and since the vertical plate 702 of the third angle steel is filled with sealant in the gap between the vertical segment 301022 of the lower insertion of the outer perimeter of the side seal 301 and the corresponding side of the outer perimeter of the side seal 301, and the side seal body 302 of the tin bath side seal 3 is located in the installation space 9 enclosed between the breast wall brick 6 and the bottom brick 8 of the tin bath, there is no need to fill the gap between the bottom surface of the side seal body 302 and the top surface of the bottom brick 8 of the tin bath, thus further reducing the amount of sealant used.
[0045] In one embodiment, the top surface of the bottom brick 8 of the tin bath is flush with the top surface of the bottom steel plate 2 of the bottom steel structure of the tin bath.
[0046] In summary, the present invention improves the sealing performance of the tin bath by interlocking the outer periphery 301 of the tin bath edge seal 3 with the first angle steel 4 installed on the lower outer side of the top cover steel structure side plate 1, or by interlocking the outer periphery 301 of the tin bath edge seal 3 with the first triangular steel 7 installed on the upper outer side of the bottom shell steel plate 2 of the bottom steel structure. This reduces the entry of unfavorable gases into the tin bath, thereby reducing defects in the produced glass plates and saving energy.
[0047] In this invention, there is no need to change the structure of the tin bath. Only the structure of the tin bath edge seal 3 needs to be designed accordingly for the first angle steel 4 or the third angle steel 7 on the tin bath, thus reducing the cost.
[0048] Among them, the tin bath edge seal 3 is not limited to ordinary edge seals, but can also be used for observation window edge seals, industrial television edge seals, operation edge seals, etc.
[0049] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
