Description

Technical Field

[0001] This utility model relates to the field of float glass production technology, and in particular to a device for preventing contamination of molten tin in a tin bath. Background Technology

[0002] In float glass production, a large amount of liquid tin is stored at the bottom of the tin bath section, allowing the molten glass to float on the tin and be spread out thinly or thickly. Some of the molten tin in the tin bath is directly exposed to the tin bath atmosphere without contacting the glass. It reacts with gases such as oxygen and sulfur dioxide in the tin bath to produce impurities such as tin oxide and tin sulfide, which adhere to the lower surface of the glass sheet and form a large amount of tin ash impurities, affecting the quality of the glass. Furthermore, the oxidation of the molten tin reduces the tin count and results in a loss of molten tin.

[0003] A search revealed a tin bath structure for flat glass manufacturing, disclosed in patent publication number CN202543034U. This structure includes a tin bath constructed from bottom and wall bricks, a tin bath top cover, and a flowing molten tin conveyor belt positioned at the bottom of the bath. Molten glass floats on the surface of the molten tin conveyor belt, with anti-adhesion gaps between the conveyor belt and the wall bricks on both sides. A graphite cover plate, with its bottom surface not exceeding the surface of the molten glass, is installed in the gap between the molten glass and the wall bricks, positioned on the wall bricks of the tin bath. By adding a graphite cover plate above the exposed molten tin, both production accidents caused by the glass ribbon sticking to the wall bricks due to excessive width and contamination caused by the molten tin evaporating due to the glass ribbon being too narrow are avoided, thus improving the finished product qualification rate.

[0004] Based on the above search and the findings of existing technologies, in existing technologies similar to the disclosed tin bath structure for glass manufacturing, the graphite cover plate is directly fixed to the wall bricks of the tin bath, which is inconvenient for regular cleaning of the molten tin surface, and also inconvenient for cleaning the lower surface of the graphite cover plate. Therefore, a tin bath molten tin anti-contamination device is proposed to improve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a device for preventing contamination of molten tin in a solder bath, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a device for preventing contamination of molten solder in a solder bath, comprising a graphite cover plate fitted to the inner wall of the solder bath, and further comprising:

[0007] The lifting drive device has a fixed base installed at the bottom of the outside of the tin bath. The fixed base is fixed to the ground. The top output end of the lifting drive device is fixed with an inverted L-shaped mounting base.

[0008] A connector that connects the inverted L-shaped mounting base to the graphite cover plate;

[0009] An auxiliary cleaning mechanism is installed on an inverted L-shaped mounting base to clean the lower surface of the graphite cover plate.

[0010] As a further supplement to this solution, a water tank is also included. The water tank is fixed to the top of the inverted L-shaped mounting base. The connector is a pipe body. The two ends of the connector are fixedly connected to the opposite two sides of the water tank, and the middle part of the connector is connected to the upper end of the graphite cover plate.

[0011] As a further supplement to this solution, the connector is an aluminum-plated tube, and the connector is detachably connected to the graphite cover plate.

[0012] As a further supplement to this solution, the upper end of the graphite cover plate is provided with a slot, and the middle part of the connector is engaged with the inside of the slot.

[0013] As a further supplement to this solution, the auxiliary cleaning mechanism includes an electric telescopic device, a scraper, and a collection box;

[0014] The electric telescopic device is installed on the side of the inverted L-shaped mounting base. The output end of the electric telescopic device is set towards the side of the tin bath and is fixed to the scraper. The collection frame is fixed on the side of the scraper away from the electric telescopic device, and the upper end of the collection frame is lower than the upper end of the scraper. The electric telescopic device drives the scraper to move against the lower surface of the graphite cover plate.

[0015] As a further supplement to this solution, the lower surface of the graphite cover plate is set as an inclined surface, and the inclined surface is set downward towards the side closest to the sidewall of the tin bath.

[0016] In summary, the technical effects and advantages of this utility model are as follows:

[0017] 1. In this utility model, by setting up a lifting drive device and an auxiliary cleaning mechanism including an electric telescopic device, a scraper and a collection frame, when it is necessary to clean the surface of the molten solder and the graphite cover plate, the lifting drive device drives the inverted L-shaped mounting base to rise, and the inverted L-shaped mounting base carries the graphite cover plate up through the connecting piece to facilitate cleaning the surface of the molten solder. When the graphite cover plate is moved up to the point where its lower end is higher than the upper end of the molten solder bath, the electric telescopic device drives the scraper to move against the lower surface of the graphite cover plate, and the scraper scrapes off the impurities attached to the lower surface of the graphite cover plate. The scraped-off impurities fall into the collection frame for collection, making the cleaning operation more convenient.

[0018] 2.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Reference Figure 1-5 The device shown is a molten tin bath anti-contamination device, which includes a graphite cover plate 6 that is attached to the inner wall of the molten tin bath, as well as a lifting drive device 2, a connector 5 and an auxiliary cleaning mechanism.

[0028] Among them, the lifting drive device 2 is located at the bottom of the outside of the tin bath and is fixed to the ground. The top output end of the lifting drive device 2 is fixed to the inverted L-shaped mounting base 3. The connector 5 is connected between the inverted L-shaped mounting base 3 and the graphite cover plate 6. The auxiliary cleaning mechanism is installed on the inverted L-shaped mounting base 3 to clean the lower surface of the graphite cover plate 6.

[0029] Regarding the auxiliary cleaning mechanism, specifically, the auxiliary cleaning mechanism includes an electric telescopic device 7, a scraper 8, and a collection frame 9. The electric telescopic device 7 is installed on the side of the inverted L-shaped mounting base 3. The output end of the electric telescopic device 7 is set towards the side of the tin bath and is fixed to the scraper 8. The collection frame 9 is fixed to the side of the scraper 8 away from the electric telescopic device 7, and the upper surface of the collection frame 9 is lower than the upper surface of the scraper 8. The electric telescopic device 7 drives the scraper 8 to move against the lower surface of the graphite cover plate 6.

[0030] When it is necessary to clean the surface of the molten solder and the graphite cover plate 6, the lifting drive device 2 drives the inverted L-shaped mounting base 3 to rise. The inverted L-shaped mounting base 3 then moves the graphite cover plate 6 upward through the connector 5, making it easier to clean the surface of the molten solder. When the graphite cover plate 6 moves up to the point where its lower end is higher than the upper end of the molten solder bath, the electric telescopic device 7 drives the scraper 8 to move against the lower surface of the graphite cover plate 6. The scraper 8 scrapes off the impurities attached to the lower surface of the graphite cover plate 6, and the scraped-off impurities fall into the collection frame 9 for collection.

[0031] To prevent the connector 5 from deforming due to heat, the tin bath anti-contamination device also includes a water tank 4, which is fixed to the top of the inverted L-shaped mounting base 3. The connector 5 is a pipe, with both ends of the connector 5 fixedly connected to the opposite sides of the water tank 4. The middle part of the connector 5 is connected to the upper end of the graphite cover plate 6. In addition to the water tank 4 and the connector 5, a cooler and a circulation pump for circulating and cooling the water are also provided and installed according to the conventional circulating cooling principle.

[0032] Among them, connector 5 is an aluminum-plated tube, and connector 5 is detachably connected to graphite cover plate 6. Specifically, for example... Figure 1 and Figure 2 As shown, the upper end of the graphite cover plate 6 is provided with a slot 601, and the middle part of the connector 5 is engaged with the inner side of the slot 601.

[0033] To easily adapt to the varying flow width requirements of molten glass under different processes, the lower surface of the graphite cover plate 6 is designed as a slope 61, with the slope 61 tilting downwards towards the side closest to the tin bath sidewall. Adjusting the height of the graphite cover plate 6 is sufficient to accommodate different flow widths of molten glass. Specifically: Figure 3 The flow width of the molten glass in the glass is less than Figure 4 The width of the flow of molten glass in the glass is then Figure 3 The height of the graphite cover plate 6 in the middle is lower than Figure 4 The graphite cover plate in the middle is 6 meters high.

[0034] The above solution can prevent molten tin from contacting air, thereby effectively preventing molten tin oxidation and sulfidation pollution, avoiding the generation of oxides, sulfides and other pollutants from molten tin oxidation, solving the defects caused by tin contamination under the glass plate. A graphite cover plate 6 is used to cover the molten tin, and it does not react with the molten tin and is resistant to high temperature and oxidation. An aluminum-plated tube is used as a fixed support for the graphite cover plate 6 to prevent the graphite cover plate 6 from shifting with the flow of molten tin. Moreover, the device is easy to install, has a high safety factor, and can be used in continuous production.

[0035] The working principle of this utility model is as follows: When it is necessary to clean the surface of the molten solder and the graphite cover plate 6, the lifting drive device 2 drives the inverted L-shaped mounting base 3 to rise. The inverted L-shaped mounting base 3 then moves the graphite cover plate 6 upward through the connector 5, which facilitates the cleaning of the molten solder surface. When the graphite cover plate 6 moves up to the point where its lower end is higher than the upper end of the molten solder bath, the electric telescopic device 7 drives the scraper 8 to move against the lower surface of the graphite cover plate 6. The scraper 8 scrapes off the impurities attached to the lower surface of the graphite cover plate 6, and the scraped-off impurities fall into the collection frame 9 for collection.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
