Description

Technical Field

[0001] This utility model belongs to the field of borosilicate glass production technology, specifically relating to a borosilicate glass liquid clarification device. Background Technology

[0002] In the production of borosilicate glass, especially in the production of high-quality borosilicate glass products, it is necessary to thoroughly remove the bubbles from the borosilicate glass melt before it is formed. This process is called the clarification of the borosilicate glass melt. During the clarification process, the borosilicate glass melt is also homogenized.

[0003] In Chinese Patent No. CN 209797747 U, a glass liquid clarification device is disclosed, which includes a glass flow channel, a glass liquid in the glass flow channel, a clarification tank at the bottom of the glass flow channel, a discharge pipe connected to the clarification tank, a corresponding plug on the discharge pipe, a wire connected to the clarification tank on one side of the plug, the wire being connected to a mains power supply, an arched top on the glass flow channel above the clarification tank, and a set of exhaust pipes on the top cover of the arched top. However, the above-mentioned device has the following problems during use: Since it is impossible to actively push the impurities that have settled in the clarification tank into the discharge pipe, relying solely on the thrust of the residual borosilicate glass liquid flow is insufficient to allow all impurities to enter the discharge pipe. Some impurities will remain inside the clarification tank and gradually solidify at the bottom of the clarification tank as the heating unit inside the clarification tank closes. These solidified impurities will hinder the subsequent flow of borosilicate glass liquid, causing impurities to accumulate in the clarification tank and preventing normal discharge of impurities. Therefore, this application proposes a borosilicate glass liquid clarification device. Utility Model Content

[0004] The purpose of this invention is to provide a borosilicate glass liquid clarification device to solve the problem mentioned in the background art that, relying on the thrust of the residual borosilicate glass liquid during flow, impurities cannot be completely allowed to enter the unloading pipe, and some impurities remain inside the clarification tank, gradually solidifying at the bottom of the clarification tank as the heating unit inside the clarification tank closes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a borosilicate glass liquid clarification device, comprising a flow channel, a clarification tank, and a heating unit. The flow channel is connected to the clarification tank, and a discharge pipe is provided inside the clarification tank. The heating unit is used to raise the temperature of the borosilicate glass liquid inside the clarification tank. An extension box is provided on the upper side of the clarification box, and a box cover is provided on the top of the extension box. An exhaust pipe communicating with the clarification box is inserted into the box cover. The tank cover is equipped with a sewage discharge drive unit, a movable plate connected to the sewage discharge drive unit, a pull rod inserted into the movable plate, a movable frame connected to the pull rod, and a waste push plate installed on the movable frame for pushing impurities to settle at the bottom of the clarification tank. The unloading pipe is equipped with a plug that matches the inner opening of the unloading pipe, a lifting drive unit connected to the plug, and a waste collection box located on the lower side of the unloading pipe.

[0006] Preferably, two auxiliary rods are inserted into the movable plate, the auxiliary rods are distributed parallel to the pull rod, and the two auxiliary rods are located on both sides of the pull rod.

[0007] Preferably, the height-increasing box is provided with an auxiliary hole that slides with the auxiliary rod.

[0014] Preferably, the movable frame is located above the outer wall of the clarification tank, and the movable frame is slidably engaged with the outer wall of the clarification tank.

[0015] Beneficial effects: This utility model provides a borosilicate glass liquid clarification device. After the sewage discharge drive unit is started, it can drive the moving plate to move. When the moving plate moves, it can drive the moving frame to move through the pull rod. During the movement of the waste push plate on the moving frame inside the clarification tank, it will gather the impurities at the bottom of the clarification tank and push the impurities into the discharge pipe.

[0018] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0019] like Figures 1-4 As shown in the figure, the present invention provides a borosilicate glass clarification device, including a flow channel 1, a clarification tank 2, and a heating unit 4. The flow channel 1 is connected to the clarification tank 2. The heating unit 4 is used to raise the temperature of the borosilicate glass molten inside the clarification tank 2. A discharge pipe 3 is provided inside the clarification tank 2. At high temperature, the bubbles inside the borosilicate glass molten are discharged, and the impurities in the borosilicate glass molten will settle to the bottom of the clarification tank 2 under the action of gravity. These impurities can be discharged through the discharge pipe 3 at the bottom.

[0020] In order to expel the impurities accumulated at the bottom of the clarification tank 2 and gather them at the discharge pipe 3, an elevation box 5 is provided on the upper side of the clarification tank 2. The top of the elevation box 5 is provided with a box cover 6. An exhaust pipe 7 connected to the clarification tank 2 is inserted into the box cover 6. Excess gas in the borosilicate glass liquid is discharged from the exhaust pipe 7. A corresponding power pump can be installed at the exhaust pipe 7 to keep the top of the inner side of the elevation box 5 under negative pressure, so that the gas can be discharged from the clarification tank 2.

[0021] Specifically, the cover 6 is equipped with a sewage discharge drive unit 8, a movable plate 9 connected to the sewage discharge drive unit 8, a pull rod 10 inserted into the movable plate 9, a movable frame 12 connected to the pull rod 10, and a waste push plate 13 installed on the movable frame 12 for pushing the impurities to settle at the bottom of the clarification tank 2.

[0022] More specifically, two auxiliary rods 11 are inserted into the movable plate 9. The auxiliary rods 11 are distributed parallel to the pull rod 10, and the two auxiliary rods 11 are located on both sides of the pull rod 10. The heightening box 5 is provided with auxiliary holes that slide with the auxiliary rods 11. Furthermore, a wear-resistant sleeve that mates with the auxiliary rods 11 is provided at the auxiliary hole. The wear-resistant sleeve slides with the auxiliary rods 11, and the wear-resistant sleeve is detachably connected to the auxiliary hole in the heightening box 5. In this way, the auxiliary rods 11 and the wear-resistant sleeve slide relative to each other. When sliding, the wear-resistant sleeve is worn, but the auxiliary hole is not directly damaged.

[0023] For reference Figure 3 The waste pusher plate 13 includes two oppositely distributed scrapers with a gap between them.

[0024] To guide the movement of the movable frame 12, a slider 14 and a track 15 that slides with the slider 14 are provided at the movable frame 12. The track 15 is installed on the inner wall of the riser box 5, and there are two sets of tracks 15. The two sets of tracks 15 are set on two parallel inner walls inside the riser box 5, and the tracks 15 are parallel to the feeding direction of the sewage discharge drive unit 8. The bottom of the movable frame 12 can be made of high-temperature resistant graphite or clay, which can be preserved in high-temperature borosilicate glass liquid for a long time. The parts that come into direct contact with the borosilicate glass liquid can all be made of corresponding high-temperature resistant materials.

[0025] It should be noted that the inner wall of the heightening box 5 is provided with a groove, and the movable frame 12 slides in the groove. The movable frame 12 is located above the outer wall of the clarification box 2, and the movable frame 12 slides in the outer wall of the clarification box 2.

[0026] The sewage discharge drive unit 8 can be a hydraulic cylinder. A controller and power supply are installed outside the clarification tank 2 to control the sewage discharge drive unit 8. After the sewage discharge drive unit 8 is started, it can drive the moving plate 9 to move. When the moving plate 9 moves, it can drive the moving frame 12 to move via the pull rod 10. During the movement of the waste push plate 13 on the moving frame 12 inside the clarification tank 2, it gathers the impurities at the bottom of the clarification tank 2 and pushes them into the discharge pipe 3. This completes the cleaning of the impurities at the bottom of the clarification tank 2. Discharge can be carried out at high temperatures and before the impurities melt, thus preventing the cooled impurities from directly adhering to the bottom of the clarification tank 2 and reducing the difficulty of cleaning. The length of the top of the discharge pipe 3 corresponds to the width of the clarification tank 2, while the bottom is equipped with a funnel-shaped gathering structure to allow impurities to collect and eventually enter the waste collection box 18.

[0027] In order to control the unloading pipe 3, a plug 16 that cooperates with the inner opening of the unloading pipe 3, a lifting drive unit 17 connected to the plug 16, and a waste collection box 18 located on the lower side of the unloading pipe 3 are provided at the unloading pipe 3.

[0028] The lifting drive unit 17 can be a hydraulic cylinder, and there is a gap between the lifting drive unit 17 and the waste collection box 18.

[0029] In summary, this utility model embodiment provides a borosilicate glass liquid clarification device. After the sewage discharge drive unit 8 is started, it can drive the moving plate 9 to move. When the moving plate 9 moves, it can drive the moving frame 12 to move through the pull rod 10. During the movement of the waste push plate 13 on the moving frame 12 inside the clarification tank 2, it will gather the impurities at the bottom of the clarification tank 2 and push the impurities into the discharge pipe 3. In this way, the cleaning work of the impurities at the bottom of the clarification tank 2 is completed. The material can be discharged at a high temperature and when the impurities have not melted. This can avoid the impurities after cooling directly adhering to the bottom of the clarification tank 2 and reduce the difficulty of cleaning the impurities.

[0030] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
