Description

Technical Field

[0001] This utility model relates to the field of glass preparation technology, and in particular to a durable edge-blocking brick structure. Background Technology

[0002] In the industrial production of microcrystalline glass sheets, the melt crystallization method is one of the mainstream processes. Its core process is as follows: high-temperature molten glass is conveyed to the rolling mill through the feed channel, and is quickly shaped into a slab by the water-cooled rolling mill. Then, it enters the crystallization kiln to complete the crystal phase transformation. At the junction of the feed channel and the rolling mill, the lip brick, as a key transition component, has edge bricks at both ends that play an important role in restricting the lateral flow of molten glass and controlling the width of the sheet.

[0003] Edge retaining bricks are typically made of refractory materials such as clay, sillimanite, sintered zirconium, and mullite. While these materials possess some high-temperature resistance, they are inherently brittle, and their tips (the "nose" closest to the calendering roll) are often thin due to structural design requirements, making them highly susceptible to breakage under the impact of high-temperature molten glass and mechanical vibration of the calendering roll. This breakage not only causes molten glass to spill out from the damaged area, resulting in uneven edges, but may also lead to production line shutdowns for component replacement, severely impacting production efficiency.

[0005] A durable edge-blocking brick structure according to a first aspect of the present invention is provided on both sides of the top surface of the lip brick, with a calendering machine behind it. The calendering machine includes an upper calendering roll and a lower calendering roll, and includes an edge-blocking brick body, comprising a brick body and a tip. The tip is located at the rear end of the brick body and is integrally formed with the brick body. One end of the tip near the calendering machine extends between the upper calendering roll and the lower calendering roll, and the end has an upper arc surface and a lower arc surface that respectively match the surface curvature of the upper calendering roll and the lower calendering roll. A baffle is detachably installed on one side of the tip to isolate the molten glass from the tip. The baffle covers the tip and is set in accordance with the outer contour of the tip. A positioning part extends forward from the baffle and engages with the brick body to position the baffle relative to the edge-blocking brick body.

[0006] A durable edge-blocking brick structure according to an embodiment of the present invention has at least the following technical effects: By setting the baffle, the structural strength of the edge-blocking brick body is improved, the thinner tip is protected, and the molten glass can be prevented from eroding the tip, maintaining the stability of the molten glass strip width exiting the rolling mill and improving production efficiency.

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They 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, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 utility model based on the specific circumstances.

[0028] Reference Figures 1 to 3 A durable edge brick structure of this utility model is provided on both sides of the top surface of the lip brick 110, and a calender is provided behind it. The calender includes an upper calendering roller 120 and a lower calendering roller 130, and includes an edge brick body 100, a baffle 200, and a positioning part 300.

[0029] Reference Figure 1 The edge-blocking brick 100 includes a brick body 101 and a tip 102. The tip 102 is located at the rear end of the brick body 101 and is integrally formed with the brick body 101. (Refer to...) Figure 3 The tip 102 extends from one end near the calender to between the upper calender roll 120 and the lower calender roll 130, and the end has an upper arc surface and a lower arc surface that match the surface curvature of the upper calender roll 120 and the lower calender roll 130, respectively.

[0030] The baffle brick 100 is made of one or a combination of zircon mullite, α-β fused alumina, sillimanite, clay brick, and fused silica. The baffle 200 is made of heat-resistant steel and is detachably installed on the side of the tip 102 facing the molten glass. It is used to isolate the molten glass from the tip 102. The baffle 200 covers the tip 102 and is set in accordance with the outer contour of the tip 102. That is, the baffle 200 has the same shape as the tip 102 and is larger than or equal to the size of the tip 102. In use, the baffle 200 can extend between the upper calender roll 120 and the lower calender roll 130 to fill the gap as much as possible to prevent the molten glass from overflowing.

[0031] By setting baffle 200, the structural strength of the baffle brick 100 is improved. The force generated when the baffle brick 100 is heated and expanded acts on this heat-resistant steel plate, thereby protecting the thinner tip 102 and preventing the glass melt from eroding the tip 102. This maintains the stability of the glass melt width exiting the rolling mill and improves production efficiency.

[0032] Because the baffle 200 is irregularly shaped, and given that the baffle 200 is larger than the tip 102, it requires multiple adjustments before being properly installed. Quickly positioning the baffle 200 on the surface of the tip 102 would improve production efficiency. Therefore, this invention also includes a positioning part 300, which extends forward from the baffle 200. The positioning part 300 partially engages with the brick body 101 to position the baffle 200 relative to the edge brick 100, thus improving the efficiency of manually aligning the baffle 200 with the tip 102 during installation.

[0033] Reference Figure 2 In some embodiments of this utility model, the baffle 200 is installed on the tip 102 by a connector. The baffle 200 and the tip 102 are respectively provided with a first connecting hole 201 and a second connecting hole 103 that match the connector. When the positioning part 300 cooperates with the brick body 101, the first connecting hole 201 and the second connecting hole 103 are aligned for the installation of the connector.

[0034] In a further embodiment of this utility model, the connector is a screw 210. A first connecting hole 201 is opened on the side of the baffle 200 facing the tip 102, and a second connecting hole 103 passes through the tip 102. Both the first connecting hole 201 and the second connecting hole 103 are provided with internal threads adapted to the screw 210. After the baffle 200 is positioned on one side of the tip 102, the screw 210 is inserted from the end away from the baffle 200. The screw 210 gradually passes through the tip 102 and connects with and tightens with the baffle 200. The end remaining outside the tip 102 is fixed with a nut 211.

[0035] In some embodiments of this utility model, the brick body 101 is provided with a positioning groove 104 on the side facing the molten glass. The positioning groove 104 is located at a corner of the top of the brick body 101 near the tip 102, which can be inserted into the positioning part 300 and engage with the positioning part 300. The baffle 200 rests on the brick body 101 through the positioning part 300 and quickly and accurately aligns with the tip 102.

[0036] In a further embodiment of this utility model, the bottom of the positioning part 300 is arc-shaped and the transition at the connection with the baffle 200 is smooth, which can avoid the steel baffle 200 from colliding and being damaged by the brick body 101 during the positioning process, and can also reduce the risk of accidental injury during manual operation due to the sharp edges of the steel baffle 200.

[0037] In a further embodiment of the present invention, an isolation fastening pad 105 is attached to the surface of the positioning groove 104 that contacts the positioning part 300. The isolation fastening pad 105 can increase the friction when the positioning part 300 is installed. After the positioning part 300 is installed into the positioning groove 104, the isolation fastening pad 105 is pressed to prevent the baffle 200 from falling off during positioning.

[0038] In addition, a more reliable method can be used to prevent the baffle 200 from falling off. In other embodiments of this utility model, the positioning part 300 is also provided with an anti-detachment part 310. One side of the positioning groove 104 that contacts the positioning part 300 is provided with an anti-detachment hole 106 that matches the anti-detachment part 310. The anti-detachment part 310 is used to insert into the anti-detachment hole 106, thereby strengthening the connection and cooperation between the positioning part 300 and the brick body 101.

[0039] Specifically, the positioning groove 104 and the positioning part 300 have at least two contact surfaces. The positions of the anti-detachment hole 106 and the anti-detachment part 310 determine the installation direction of the baffle 200. If the anti-detachment hole 106 is located on the side of the positioning groove 104, the baffle 200 needs to be installed from the side, and there is still a possibility of it falling off from the side. If the anti-detachment hole 106 is located on the bottom surface of the positioning groove 104, the baffle 200 is installed from top to bottom, which is a more reasonable installation method, and it cannot detach upwards without external force. Therefore, in a further embodiment of this utility model, the anti-detachment part 310 is located on the bottom surface of the positioning part 300, and the anti-detachment hole 106 is located on the bottom surface of the positioning groove 104.

[0040] In some embodiments of this utility model, the side of the tip 102 facing the molten glass is provided with an installation groove for installing the baffle 200. When the baffle 200 is installed in the installation groove, the outer side of the baffle 200 is flush with the surface of the brick body 101, so that the edge brick structure maintains its original size to meet the current standards.

[0041] In a further embodiment of this utility model, an isolation layer 220 is provided on the side of the baffle 200 facing the tip 102, the baffle 200 covers the isolation layer 220, and the isolation layer 220 covers the tip 102. The isolation layer 220 has the function of buffering the thermal expansion stress of the edge brick 100 and heat preservation. It is preferably made of flexible material, such as microcrystalline fiber pads or heat insulation cotton, which can be selected as needed, and its thickness is set to 1mm-10mm.

[0042] In the description of this utility model, it should be noted that the terms "vertical", "up", "down", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and 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 this utility model.

[0043] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" 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.
