[0033] The present utility model provides a lip brick 100 for a glass production runner. The lip brick 100 includes a lower lip brick 1, a fixing member 2 and an upper lip brick 3. The lower lip brick 1 is used to connect to the cooling water package of the glass production runner; the fixing member 2 is connected to the side of the lower lip brick 1 facing away from the cooling water package; the upper lip brick 3 is detachably connected to the side of the fixing member 2 facing away from the lower lip brick 1, and the upper lip brick 3 is used to divert the glass liquid.
[0034] It can be understood that the lip brick 100 is located at the outlet of the glass kiln runner and is used to guide the molten glass liquid to the press roller of the calender to achieve the calendering and forming of the glass. The lip brick 100 can be installed on the cooling water jacket to better control the temperature of the lip brick 100 and prevent it from being damaged due to high temperature.
[0035] In this embodiment, the lip brick 100 can be divided into a lower lip brick 1, a fixing member 2 and an upper lip brick 3. The lower lip brick 1 can be installed on the cooling water jacket or the support structure. The lower lip brick 1, the fixing member 2 and the upper lip brick 3 are stacked in sequence from bottom to top, and the upper lip brick 3 is detachably connected to the fixing member 2. Since only the upper lip brick 3 actually contacts the glass liquid during glass production, it is mainly the upper lip brick 3 that is eroded and damaged. When replacing, only the upper lip brick 3 can be replaced specifically, so that the renewal cost of the lip brick 100 can be reduced and the production efficiency can be improved.
[0036] In actual implementation, the upper lip brick 3 can be connected to the fixing member 2 by bolts or connected to the fixing member 2 through a snap-fit structure to achieve the detachable connection between the upper lip brick 3 and the fixing member 2.
[0037] In an embodiment of the present utility model, one of the upper lip brick 3 and the fixing member 2 is provided with a chute 31, and the other of them is correspondingly provided with a sliding protrusion 22 corresponding to the chute 31, and the sliding protrusion 22 is slidably limited in the chute 31.
[0038] In this embodiment, the upper lip brick 3 and the fixing member 2 are slidably connected through the sliding cooperation of the chute 31 and the sliding protrusion 22. When replacing the upper lip brick 3, the old upper lip brick 3 can be pushed out from the fixing member 2 along the extending direction of the chute 31 or the sliding protrusion 22, and then the new upper lip brick 3 can be pushed into the fixing member 2 along the extending direction of the chute 31 or the sliding protrusion 22 to complete the replacement of the upper lip brick 3. In this way, the upper lip brick 3 can be moved by pushing, without lifting and moving the entire upper lip brick 3, which greatly reduces the replacement difficulty of the upper lip brick 3 and is beneficial to improving the replacement efficiency of the upper lip brick 3.
[0039] It can be understood that the chute 31 and the sliding protrusion 22 extend along the length direction of the upper lip brick 3 or the fixing member 2. The side of the upper lip brick 3 facing the fixing member 2 can be concave, and the side of the fixing member 2 facing the upper lip brick 3 can be convex. The concave part forms the chute 31, and the convex part forms the sliding protrusion 22. The cooperation of the chute 31 and the sliding protrusion 22 can realize the positioning installation of the upper lip brick 3 and the fixing member 2, and can also realize the limit of the upper lip brick 3 in the width direction. When the upper lip brick 3 and the fixing member 2 are connected, the opposite sides of the upper lip brick 3 and the fixing member 2 just fit, so as to increase the contact area between the upper lip brick 3 and the fixing member 2, reduce the wear of the fixing member 2 and extend the service life of the fixing member 2.
[0040] In actual implementation, sliding protrusions 22 can also be formed on both sides of the recess, and a sliding groove 31 can be formed between the two protrusions. The sliding groove 31 is provided through the end face of the upper lip brick 3 or the fixing member 2.
[0041] In one embodiment, the lip brick further includes a limiting member. One end of the limiting member is rotatably connected to the end face of the fixing member 2 or the lower lip brick 1, and the other end of the limiting member is used to abut against the upper lip brick 3.
[0042] In this embodiment, after the upper lip brick 3 is installed in place, the limiting member can be rotated so that the other end of the limiting member abuts against the end face of the upper lip brick 3, preventing the upper lip brick 3 from sliding relative to the fixing member 2 during the glass production process, resulting in abnormal flow of the glass liquid.
[0043] In actual implementation, the sliding groove 31 can be provided through one end face or both end faces of the upper lip brick 3 or the fixing member 2, and the limiting member is provided corresponding to the through end of the sliding groove 31. The limiting member can also be connected to the lower lip brick 1, the fixing member 2, and the upper lip brick 3 in a detachable connection manner to relatively fix the lower lip brick 1, the fixing member 2, and the upper lip brick 3, avoiding relative displacement between them and affecting the normal production of the glass. The limiting member can be a fixing iron sheet, which can be connected to the lower lip brick 1, the fixing member 2, and the upper lip brick 3 by bolts. The limiting member can also be other fixing structures, which are not specifically limited herein.
[0044] In one embodiment of the present utility model, the sliding groove 31 includes at least two, and the two sliding grooves 31 are arranged at intervals, and the sliding protrusions 22 are arranged in one-to-one correspondence with the sliding grooves 31.
[0045] In this embodiment, the number of the sliding grooves 31 provided can be two, three, four, etc. The sliding protrusions 22 are arranged in one-to-one correspondence with the sliding grooves 31 to ensure the stability when the upper lip brick 3 and the fixing member 2 slide relative to each other. The number of the sliding grooves 31 provided can be set according to requirements, which is not specifically limited herein.
[0046] In one embodiment of the present utility model, the fixing member 2 is provided with a limiting protrusion 21, and the lower lip brick 1 is provided with a limiting groove 11 corresponding to the limiting protrusion 21, and the limiting protrusion 21 is limited in the limiting groove 11.
[0047] In this embodiment, the fixing member 2 and the lower lip brick 1 can also be detachably connected through the cooperation of the limiting protrusion 21 and the limiting groove 11 to facilitate the replacement of the fixing member 2. In actual implementation, the limiting groove 11 only penetrates the side surface of the lower lip brick 1 and does not penetrate the end face in the length direction of the lower lip brick 1. When installing the fixing member 2, the fixing member 2 is placed from above the lower lip brick 1 so that the limiting protrusion 21 is snapped into the limiting groove 11, and thus the positioning installation of the fixing member 2 can be completed.
[0048] In actual implementation, limiting protrusions 21 can also be formed on both sides of the limiting groove 11, and a limiting groove 11 can be formed between the two limiting protrusions 21. When the lower lip brick 1 and the fixing member 2 are connected, the opposite sides of the lower lip brick 1 and the fixing member 2 just fit together, so as to increase the contact area between the lower lip brick 1 and the fixing member 2, reduce the wear of the fixing member 2, and extend the service life of the fixing member 2.
[0049] In an embodiment of the present utility model, the limiting groove 11 runs through the end face of the lower lip brick 1, and the length of the limiting protrusion 21 is the same as the length of the limiting groove 11; and / or, there are multiple limiting grooves 11, and the limiting protrusions 21 and the limiting grooves 11 are arranged in one-to-one correspondence.
[0050] In this embodiment, the limiting groove 11 can also run through the end face in the length direction of the lower lip brick 1, so that the fixing member 2 can also be pushed along the limiting groove 11, which is convenient for the installation of the fixing member 2. The limiting groove 11 can run through only one end face in the length direction of the lower lip brick 1 or run through two end faces in the length direction of the lower lip brick 1, and no specific limitation is made here.
[0051] In an embodiment of the present utility model, the fixing member 2 is made of graphite.
[0052] In this embodiment, the fixing member 2 is made of graphite. The graphite fixing member 2 has a unique flaky structure and excellent lubricating performance, so as to further reduce the frictional resistance between the upper lip brick 3 and the fixing member 2, enabling the upper lip brick 3 to be smoothly pushed out along the sliding groove 31 when being replaced. At the same time, graphite also has the properties of high temperature resistance and oxidation resistance, reducing the wear of the fixing member 2 and extending the service life of the fixing member 2.
[0053] In an embodiment of the present utility model, the thickness range of the fixing member 2 is 20 mm to 30 mm; and / or, the depth range of the sliding groove 31 is 30 mm to 50 mm; and / or, the width range of the sliding groove 31 is 30 mm to 50 mm.
[0054] In this embodiment, the thickness of the fixing member 2 can be 20 mm, 21 mm, 22 mm, 24 mm, 25 mm, 26 mm, 28 mm, 30 mm, etc., and the depth or width of the sliding groove 31 can be 30 mm, 32 mm, 34 mm, 36 mm, 38 mm, 40 mm, 42 mm, 44 mm, 46 mm, 48 mm, 50 mm, etc., and no specific limitation is made here. In actual implementation, the upper lip brick 3 or the lower lip brick 1 can be made of materials such as zircon mullite, fused quartz, and sillimanite.
[0055] In actual implementation, if the fixing member 2 is too thick, it is not conducive to the installation of the fixing member 2. If the fixing member 2 is too thin, the service life of the fixing member 2 is short and it needs to be frequently replaced. If the sliding groove 31 is too narrow, it is inconvenient for the sliding protrusion 22 to be aligned and inserted into the sliding groove 31. If the sliding groove 31 is too wide, the side wall of the sliding groove 31 may be too narrow, reducing the connection strength between the upper lip brick 3 and the fixing member 2. If the sliding groove 31 is too deep, it may cause a reduction in the strength of the upper lip brick 3 or the fixing member 2, and it is not easy for the sliding protrusion 22 to slide along the sliding groove 31. If the sliding groove 31 is too shallow, the sliding protrusion 22 may come out of the sliding groove 31.
[0056] In an embodiment of the present utility model, the cross-section of the sliding groove 31 is arranged in a dovetail shape, and the cross-sectional shape of the sliding protrusion 22 is the same as that of the sliding groove 31.
[0057] In this embodiment, the sliding groove 31 can be arranged as a dovetail groove, and the sliding protrusion 22 can also be arranged in a dovetail shape. In this way, when the sliding protrusion 22 is limited in the sliding groove 31, the sliding protrusion 22 will not come out from the side of the sliding groove 31 facing away from the groove bottom, further improving the limiting effect of the sliding groove 31 on the sliding protrusion 22. It can be understood that with the extending direction of the sliding groove 31 as the X-axis direction, the setting of the limiting member can prevent the sliding protrusion 22 from coming out of the sliding groove 31 along the X-axis direction, the side wall of the sliding groove 31 can prevent the sliding protrusion 22 from coming out of the sliding groove 31 along the Y-axis direction, and the setting of the dovetail groove can prevent the sliding protrusion 22 from coming out of the sliding groove 31 along the Z-axis direction, and the X-axis direction, Y-axis direction and Z-axis direction are perpendicular to each other in pairs.
[0058] In actual implementation, the limiting protrusion 21 and the limiting groove 11 can also be arranged in a dovetail shape.
[0059] The present utility model also proposes a calendering device, which includes a calendering runner and a calendering device. The calendering runner is provided with the lip brick 100 as described above, and the specific structure of the lip brick 100 refers to the above embodiment. Since this theme two adopts all the technical solutions of the above-mentioned all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated here one by one. Among them, the calendering device is provided with a calendering roll, and the calendering roll is arranged opposite to the lip brick 100. The lip brick 100 is provided with an avoidance inclined surface for avoiding the calendering roll.
[0060] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
