[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] Reference Figure 1 As shown, the present invention provides a glass preparation production system, including: a melting furnace 1, a cooler 2, a first production device 3 and a second production device 4; the melting furnace 1 is suitable for heating and melting glass batch materials to generate glass liquid; the cooler 2 is connected to the melting furnace 1, and the glass liquid is cooled in the cooler 2; the first production device 3 is connected to the cooler 2, and the first production device 3 is suitable for rolling and molding the glass liquid; the second production device 4 is connected to the cooler 2, and the second production device 4 is suitable for flat drawing and molding the glass liquid; the first production device 3 and the second production device 4 are independent of each other, and the glass liquid can flow to the first production device 3 and the second production device 4 at the same time through the cooler 2, or flow to the first production device 3 or the second production device 4 in a single channel.

[0026] Specifically, the glass batch material is heated in the melting furnace 1 to form glass liquid, and after the glass liquid flows through the cooler 2 for cooling, it enters the first production device 3 and the second production device 4 separately or simultaneously, and the glass liquid is subjected to a rolling forming process in the first production device 3, and the glass liquid is subjected to a flat drawing forming process in the second production device 4. The glass preparation production system adopts a one-kiln two-line setting, and by setting the first production device 3 and the second production device 4 which are independent of each other, the two glass production processes are carried out simultaneously or alternately, thereby avoiding the interruption of the melting furnace 1, improving production efficiency, and reducing energy consumption.

[0027] It can be understood that the first production device 3 and the second production device 4 are independently arranged, so that the first production device 3 and the second production device 4 can be operated simultaneously or separately. Specifically, when the first production device 3 is put into use, the second production device 4 can be suspended, and when the second production device 4 is put into use, the first production device 3 can be suspended. This design does not need to interrupt the operation of the melting furnace 1, realizes the continuity of production, and effectively reduces the cost. The melting capacity of the melting furnace 1 is 90-100t / d (tons / day).

[0028] In some embodiments of the present invention, the glass preparation production system further includes a neck 5 , one end of which is connected to the outlet of the melting furnace 1 , and the other end of which is connected to the inlet of the cooler 2 .

[0029] Specifically, the neck 5 has multiple functions, including separating space and liquid flow regulation, regulating the convection of glass liquid, stabilizing the operating system, preventing air flow movement and cooling; specifically, the neck 5 is located between the melting furnace 1 and the cooler 2, and by changing the flow state of the glass liquid at the neck 5, the glass liquid is further homogenized and the quality of the glass liquid is improved; it can effectively prevent air flow movement, stabilize the temperature field and air flow field of the melting furnace 1, help maintain a high-temperature clarification environment, and avoid the adverse effects of colder or hotter airflow on the melting furnace 1 and the cooler 2. The design of the neck 5 allows the glass liquid passing through this area to be cooled by about 100°C. This sudden temperature drop is conducive to the absorption of microbubbles by the glass liquid and reduces the occurrence of "reboiling". The cooling effect of the neck 5 promotes the high-temperature clarification and bubble removal of the glass liquid, and helps to eliminate defects such as bubbles in the glass liquid. At the same time, the liquid flow regulation at the neck 5 also helps to homogenize the glass liquid and improve the overall uniformity of the glass.

[0030] It is understandable that the temperature in the neck 5 is 1350°C to 1500°C, and the glass liquid needs to be stirred at the neck 5 to remove bubbles in the glass liquid and maintain the temperature uniformity of the glass liquid forming flow. The temperature of the cooler 2 is 1000°C to 1200°C, which can ensure that the molten glass liquid can be homogenized and cooled to the required temperature.

[0031] In some embodiments of the present invention, the first production device 3 is provided with a first cooling section 31, and the second production device 4 is provided with a second cooling section 41. The first cooling section 31 and the second cooling section 41 are arranged at intervals, and the first cooling section 31 and the second cooling section 41 are both connected to the cooler 2. The molten glass enters the first cooling section 31 and the second cooling section 41 respectively from the cooler 2 to achieve secondary cooling.

[0032] Specifically, the first cooling section 31 and the second cooling section 41 are arranged at intervals to ensure that the cooling temperature of the glass liquid in different cooling sections is not affected. The glass liquid enters the first cooling section 31, and the temperature of the glass liquid in the first cooling section 31 is cooled to 820°C ~ 1080°C, and the temperature of the glass liquid in the second cooling section 41 is cooled to 900°C ~ 1000°C to ensure that the glass liquid can be subjected to calendering molding or flat-drawing molding processes in different production devices.

[0033] In some embodiments of the present invention, the cooler 2 is provided with a first outlet and a second outlet, the first outlet is connected to the first cooling part 31 through a first drainage channel 6, and the second outlet is connected to the second cooling part 41 through a second drainage channel 7, and the length of the first drainage channel 6 and the second drainage channel 7 is 3-5 meters.

[0034] Specifically, by setting the first drainage channel 6 and the second drainage channel 7, the glass liquid can be diverted. The setting of the first drainage channel 6 and the second drainage channel 7 can ensure that the glass liquid remains stable when transitioning from the cooler 2 to the first cooling part 31 and the second cooling part 41, thereby reducing the risk of glass ribbon breakage caused by stress concentration.

[0035] In some embodiments of the present invention, a first flow gate plate 8 is provided between the first outlet and the first drainage channel 6, and a second flow gate plate 9 is provided between the second outlet and the second drainage channel 7. The first flow gate plate 8 and the second flow gate plate 9 are suitable for controlling the flow direction of the glass liquid in the cooler 2.

[0036] Specifically, the first flow channel gate 8 and the second flow channel gate 9 are used to change the flow direction of the glass liquid. When the flow channel gate is opened, the glass liquid reaches the first production device 3 and / or the second production device 4 through the first drainage channel 6 and / or the second drainage channel 7. When the flow channel gate is closed, the glass liquid cannot reach the first production device 3 and / or the second production device 4 through the first drainage channel 6 and / or the second drainage channel 7. According to production needs, the first production device 3 and the second production device 4 can be switched by controlling the first flow channel gate 8 and the second flow channel gate 9, thereby avoiding the interruption of the operation of the melting furnace 1 and reducing production costs. And it can be adjusted in time according to the operation of the first drainage channel 6 and the second drainage channel 7, and the melting furnace 1 does not need to run at full load, reducing energy loss.

[0037] In some embodiments of the present invention, the first production device 3 includes a calendering device 32, a first annealing device 33 and a first cold end cutting device 34. The glass liquid enters the calendering device 32 from the first cooling part 31 to realize glass calendering and cooling annealing. The calendered glass enters the first annealing device 33 for annealing and is then cut in the first cold end cutting device 34.

[0038] In some embodiments of the present invention, the second production device 4 includes a second annealing device 42 and a second cold end cutting device 43 . After the molten glass enters the second annealing device 42 from the second cooling unit 41 for annealing, it is cut in the second cold end cutting device 43 .

[0039] The first annealing device 33 and the second annealing device 42 perform annealing of the glass, thereby eliminating temporary stress and permanent stress on the glass surface and producing glass products of excellent quality. After annealing, the glass is sent to the first cold end cutting device 34 and the second cold end cutting device 43, cut into specified sizes, and then taken out, boxed and packaged.

[0040] In some embodiments of the present invention, the operating temperature of the melting furnace 1 is 1450°C to 1600°C, and the operating temperature of the cooler 2 is 1000°C to 1200°C.

[0041] In some embodiments of the present invention, the working temperature of the first cooling part 31 is 820°C to 1080°C, and the working temperature of the second cooling part 41 is 900°C to 1000°C.

[0042] In some embodiments of the present invention, the first production device 3 can produce the first glass, which is a flat glass with a thickness of 1.5 mm to 6.0 mm or a glass with texture or pattern; the second production device 4 can produce the second glass, which is a glass with a thickness of less than 2.5 mm and a flat surface.

[0043] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
