[0042] In this embodiment, the lip brick heating device 100 is composed of a bracket 1, a heat preservation device 2, a heating device 3 and a control device 4. Among them, the bracket 1 is a mounting frame for the heat preservation device 2, the heating device 3 and the control device 4, providing a stable installation space for the heat preservation device 2, the heating device 3 and the control device 4; the heat preservation device 2 encloses a heat preservation space 21, and the heating device 3 is arranged in the heat preservation space 21.

The outer shell 311 and the inner shell 312 can be connected by welding, and a line channel connected to the outside is reserved on the outer shell 311, so that the heating element 32 is electrically connected to the control device 4 located outside the heating chamber 313. The inner shell 312 is provided with a ventilation hole connecting the heating chamber 313 and the placement space 33, so that the heat emitted by the heating element 32 can enter the placement space 33.

[0054] In actual implementation, the heating chamber 313 is the interlayer space inside the heating frame 31, and multiple ventilation holes can be provided. In one embodiment, a ventilation hole is provided every 300 mm on the side of the inner shell 312 corresponding to the length direction of the placement space 33, and two ventilation holes are provided on the side of the inner shell 312 corresponding to the width direction of the placement space 33. The ventilation holes can be squares with a side length of 40 mm. The actual number and size of the ventilation holes can be selected according to the size of the placement space 33.

[0055] In one embodiment of the present invention, the heat preservation device 2 is provided with a filling cavity 22 , and the filling cavity 22 is filled with heat preservation material.

[0056] In this embodiment, the heat-insulating device 2 is provided with a filling cavity 22 for filling with heat-insulating material, and the heat-insulating material in the filling cavity 22 may be heat-insulating cotton.

[0057] It can be understood that the heat preservation device 2 includes a heat preservation frame, which encloses a heat preservation space 21, and the filling cavity 22 is the interlayer space inside the heat preservation frame. In actual implementation, the heat preservation frame and the heating frame 31 can be integrally formed into a heating box, which is provided with a total of three layers of shells, from the outside to the inside, respectively, the heat preservation shell 23, the outer shell 311 of the heating frame 31 and the inner shell 312, the filling cavity 22 is formed between the heat preservation shell 23 and the outer shell 311, the heating cavity 313 is formed between the outer shell 311 and the inner shell 312, the inner shell 312 encloses a placement space 33, and the heat preservation shell 23 and the outer shell 311 are provided with a line channel connecting the heating cavity 313 and the outside, so that the heating element 32 can be electrically connected to the control device 4. The entire heating box is also enclosed to form an entry 34 connected to the placement space 33, so that the lip brick can be placed in or taken out.

[0058] Optionally, the heating box may be composed of two heating frames, which are symmetrically arranged to enclose a placement space 33. When the lip brick is placed in the placement space 33, the lip brick can be placed between the two heating frames, and then the two heating frames are assembled to enclose the placement space 33. At the same time, before the lip brick is placed in the placement space 33, a thermocouple may be set on the surface of the lip brick to detect the temperature of the lip brick in real time, and then accurately determine the heating temperature and heating rate of the lip brick. Optionally, multiple thermocouples may be installed on the top and side of the lip brick respectively to monitor the temperature of each part of the lip brick in real time, so as to facilitate real-time adjustment of the working state of the heating element 32 to prevent excessive differences in the heating rates of various parts of the lip brick.

[0059] In one embodiment, the shell of the heating frame is composed of angle steel, iron sheet and stainless steel plate.

In this way, when the heating element 32 is heated, the outer shell 311 and the inner shell 312 have a certain expansion space to prevent the stainless steel plate from being squeezed and deformed.

[0060] In one embodiment of the present invention, the lip brick heating device 100 also includes a mobile carrier 5, which is provided with a placement platform 51 for placing lip bricks. The placement platform 51 is provided with a screw propulsion device 52 for pushing the lip bricks on the placement platform 51.

[0061] In this embodiment, the lip brick can be moved into or out of the placement space 33 by the mobile carrier 5, so as to move the heated lip brick to the glass production line, which is beneficial to the safety of the operator. The lip brick is placed on the placement platform 51 of the mobile carrier 5. When the heated lip brick is transferred, the lip brick can be pushed by the screw propulsion device 52 to push the lip brick off the placement platform 51.

[0062] In actual implementation, a gap 35 connecting the placement space 33 and the entry 34 is provided at the bottom of the heat preservation box for the passage of the mobile vehicle 5. When the mobile vehicle 5 drives the lip brick to enter the placement space 33, the placement platform 51 of the mobile vehicle 5 can just block the gap 35 to ensure the sealing of the placement space 33 when the temperature rises. Optionally, an outlet connecting the placement space 33 and the gap 35 is further provided at one end of the heat preservation box away from the entry 34, and the lip brick can enter the placement space 33 from the entry 34 and leave the placement space 33 from the outlet.

[0063] The present invention also proposes an online lip brick replacement method, such as Figure 1 and Figure 2 As shown, the online lip brick replacement method applies the lip brick heating device 100 as mentioned above. The specific structure of the lip brick heating device 100 refers to the above embodiment. Since the online lip brick replacement method adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0064] The steps of the online lip tile replacement method include:

[0065] Control the mobile carrier 5 to drive the new lip brick to heat up in the placement space 33;

[0066] Control the mobile carrier 5 to move the new lip brick to the glass production line and replace the old lip brick.

[0067] In the embodiment, before replacing the old lip brick with a new one, the new lip brick is driven into the placement space 33 by the mobile carrier 5, and the new lip brick is heated to avoid excessive temperature difference between the new lip brick and the glass liquid in the glass production line, which would cause excessive temperature difference between the inside and outside of the new lip brick, inconsistent expansion speed of the inside and outside of the new lip brick, and cause cracks inside the new lip brick, thus affecting the service life of the new lip brick.

[0068] In one embodiment of the present invention, the specific steps of controlling the mobile carrier 5 to drive the new lip brick to heat up in the placement space 33 include:

[0069] Place the new lip brick on the placement platform 51, and control the moving vehicle 5 to move the new lip brick into the placement space 33;

[0070] The control device 4 controls the heating device 3 to heat up to a preset temperature at a preset heating speed.

[0071] In this embodiment, after the control device 4 moves the new lip tile into the placement space 33, the control device 4 controls the heating device 3 to heat up at a preset heating speed to avoid the new lip tile from heating up too fast, resulting in a large temperature difference between the inside and outside of the new lip tile and cracks. The preset heating speed can be selected according to the temperature expansion coefficient of the lip tile, and the preset temperature can be selected according to the glass temperature of the production line. Optionally, the preset heating speed can be 5°C / min.

[0072] In actual implementation, the specific steps of controlling the mobile carrier 5 to drive the new lip brick to heat up in the placement space 33 also include: the control device 4 controls the heating device 3 to maintain the preset temperature for a certain period of time. In this way, the new lip brick can be dried as much as possible under high temperature, and water analysis of the new lip brick during use can be avoided, resulting in bubble defects in the produced glass plate, thereby improving the production quality of the glass production line.

[0073] In actual implementation, a thermocouple can be set on the surface of the lip brick to monitor the temperature of the lip brick in real time and accurately, and then judge the temperature rise of the lip brick. If there is an accident, the operator can adjust the working state of the heating device 3 in time according to the monitored temperature.

[0074] In one embodiment of the present invention, the glass production line includes a glass liquid flow channel formed by the side bricks and the old lip bricks, a side brick fixing member for fixing the side bricks, a lip brick fixing member for fixing the lip bricks, and a calender; wherein, controlling the mobile carrier 5 to move the new lip brick to the glass production line and replacing the old lip brick includes:

[0075] Adjust the width of the glass flow channel, the spacing between the calender upper roller and the calender lower roller, and the distance between the calender and the glass flow channel;

[0076] Move the moving carrier 5 carrying the new lip brick so that the placement platform 51 is aligned with the old lip brick from the upper brick side of the glass runner;

[0077] Move the empty moving carrier 5 so that the placement platform 51 is aligned with the old lip brick from the lower brick side of the glass runner;

[0078] The new lip brick on the placement platform 51 is pushed by the screw propulsion device 52, and the old lip brick is pushed to the placement platform 51 of the empty mobile carrier 5;

[0079] Reset the width of the glass flow channel, the spacing between the calender upper roller and the calender lower roller, and the distance between the calender and the glass flow channel.

[0080] In this embodiment, the flow speed and flow width of the glass liquid can be adjusted by adjusting the width of the glass liquid flow channel, thereby controlling the flow path of the glass liquid from the glass liquid flow channel to the calendering port of the calendering machine, making the curvature larger, and at the same time adjusting the spacing between the calendering upper roller and the calendering lower roller of the calendering machine to increase the calendering port, and at the same time adjusting the distance between the calendering machine and the glass liquid flow channel opening, so that the glass liquid can also flow to the calendering port during the replacement of the new and old lip bricks. Afterwards, the mobile carrier 5 carrying the new lip brick is moved to the upper brick side of the glass flow channel and aligned with the old lip brick. The lower brick side of the glass flow channel is pre-placed with an empty mobile carrier 5, and then the new lip brick is slowly pushed by the screw propulsion device 52, and the new lip brick pushes the old lip brick onto the mobile carrier 5 on the lower brick side, so as to complete the replacement of the new and old lip bricks, and finally the width of the glass liquid flow channel opening, the spacing between the calendering upper roller and the calendering lower roller, and the distance between the calendering machine and the glass liquid flow channel opening are reset to carry out subsequent normal production.

[0081] In actual implementation, the screw propulsion device 52 can be driven manually or automatically, and the propulsion speed can be adjusted, which is not specifically limited here. The height of the mobile carrier 5 can be adjusted so that the placement platform 51 is aligned with the old lip brick. The specific adjustment values ​​of the glass liquid flow channel width, the spacing between the calendering upper roller and the calendering lower roller, and the distance between the calender and the glass liquid flow channel are determined according to the glass liquid flow trajectory.

[0082] In one embodiment of the present invention, the specific steps of adjusting the width of the glass flow channel, the spacing between the calendering upper roller and the calendering lower roller, and the distance between the calender and the glass flow channel include:

[0083] Loosen the side brick fixings on both sides, and move the side bricks on both sides relatively close to a first preset distance;

[0084] Loosen the lip brick fixings on both sides, and adjust the calendering upper roller and the calendering lower roller of the calendering machine to be relatively away from the second preset distance;

[0085] The calender is moved away from the glass liquid flow channel opening by a third preset distance.

[0086] In this embodiment, when moving the side bricks, it is necessary to first loosen the side brick fixings and push the side bricks on both sides closer to each other by a first preset distance, so as to adjust the width of the glass liquid flow channel opening by adjusting the spacing between the side bricks on both sides, wherein the first preset distance may be 400 mm. Then, loosen the lip brick fixings to make the calendering upper roller and the calendering lower roller relatively away from the second preset distance, wherein the second preset distance may be 4 mm, and finally move the calendering machine away from the glass liquid flow channel opening by a third preset distance, wherein the third preset distance ranges from 3 mm to 5 mm. In this way, the fluidity of the glass liquid is utilized so that the glass liquid can still flow normally to the calendering opening when the lip bricks are replaced.

[0087] In actual implementation, the first preset distance, the second preset distance and the third preset distance can be selected according to actual needs and are not specifically limited here. The side brick fixing member includes a moving device in the height direction and the width direction of the side brick. The moving device in the height direction can be used to adjust the distance between the side brick and the lip brick, loosen or tighten the lip brick, and the moving device in the width direction can be used to adjust the horizontal position of the side brick, thereby adjusting the spacing between the side bricks on both sides.

[0088] It is understandable that when moving the side bricks, the side bricks can be slightly lifted to loosen the side bricks, which is convenient for moving the side bricks. At the same time, it can also prevent the position of the side bricks from being moved when the new lip bricks and the old lip bricks are replaced. A graphite gasket can be arranged under the side bricks. The graphite gasket has the characteristic of not adhering to the glass liquid to prevent the glass liquid from leaking. The thickness of the graphite gasket can be 2 mm, which is not specifically limited here.

[0089] In one embodiment of the present invention, Figure 3 As shown, the lip brick includes an upper lip brick 61 , a graphite piece 62 and a lower lip brick 63 which are stacked. The new lip brick is the new upper lip brick 61 , and the old lip brick is the old upper lip brick 61 .

[0090] In this embodiment, since the lip brick is composed of an upper lip brick 61, a graphite part 62 and a lower lip brick 63, in glass production, only the upper lip brick 61 is in actual contact with the glass liquid. Therefore, when the lip brick is updated, only the upper lip brick 61 needs to be replaced, which can effectively reduce the update cost of the lip brick.

[0091] At the same time, the graphite piece 62 has good lubrication properties to reduce the resistance of the new upper lip brick 61 to push the old lip brick, thereby reducing the difficulty of updating the lip brick. It can be understood that the lip brick fixing member can fix the upper lip brick 61, the graphite piece 62 and the lower lip brick 63 respectively. When replacing the upper lip brick 61, the lip brick fixing member only loosens the upper lip brick 61 to prevent the graphite piece 62 from being displaced during the replacement of the upper lip brick 61. The upper lip brick 61, the graphite piece 62 and the lower lip brick 63 are limited by protrusions and grooves to facilitate the positioning and installation of the upper lip brick 61.

[0092] The online lip brick replacement method of the present solution can quickly replace worn or damaged lip bricks without interrupting the production line, thereby improving the production efficiency of glass and meeting the demand for efficient production in the glass manufacturing industry. The online lip brick replacement method also reduces the workload of operators, while improving the accuracy and safety of lip brick replacement, meeting the demand for high precision and high efficiency in the field of calender equipment. In the online lip brick replacement method, the screw propulsion device 52, the side brick fixing member and the lip brick heating device 100 can be driven and controlled automatically, which not only improves production efficiency but also reduces manual intervention.

[0093] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
