Description

Technical Field

[0001] This utility model belongs to the field of float glass production equipment, specifically relating to a bubble elimination device at the bottom of a tin bath. Background Technology

[0002] In the float glass production process, the tin bath is a crucial area for glass ribbon formation. Molten glass flows from the channel onto the surface of the molten tin, where it is protected by a protective gas (…). and The glass is spread out and cooled in an environment to form a solid shape. If bubbles appear at the bottom of the tin bath, open bubbles will form on the lower surface of the glass plate, seriously affecting product quality and even causing the entire batch of glass to be scrapped. To solve this technical problem, there is a bubble elimination device in the prior art. However, the existing bubble elimination device still has some technical defects. First, the existing devices usually open blind holes of the same length at the bottom of the tin bath. Since the gas emission rate in the refractory bricks at the bottom of the bath is not uniform, some gas may still rise and escape from the bottom of the tin bath during the exhaust process of the vacuum pump. Second, the blind holes left at the bottom of the tin bath after the bubble is eliminated and the device is removed may cause instability of the bottom surface of the tin bath and also damage the tin bath.

[0003] In view of this, in order to solve the above-mentioned technical problems, this utility model proposes a bubble elimination device that extracts gas from the bottom of the tin bath through blind holes of different depths to avoid the formation of bubbles that affect the quality of glass, and forms support inside the blind holes to avoid instability at the bottom of the tin bath. The device has a simple structure, is easy to disassemble and assemble, and has good defoaming performance. Utility Model Content

[0004] This utility model provides a bubble elimination device for the bottom of a tin bath. It has a simple structure, is easy to assemble and disassemble, and has good defoaming performance. It extracts gas from the bottom of the tin bath through blind holes of varying depths to prevent bubbles from forming and affecting glass quality. Furthermore, it provides support within the blind holes to prevent instability at the bottom of the tin bath. The specific solution is as follows: A bubble elimination device for the bottom of a solder bath includes a solder bath. At least one group of blind holes is formed along the length of the bottom surface of the solder bath. The group of blind holes consists of three blind holes with increasing depths from left to right. A support tube is inserted into the lower part of each blind hole. Several through holes are evenly spaced along the axial direction of the support tube. An installation ring is provided on the bottom surface of the solder bath and is fixedly connected to the support tube. A branch pipe is detachably connected to the lower end of the installation ring. The branch pipe is connected to a conduit, which is connected to a main pipe. The free end of the main pipe is connected to a vacuum pump. A pressure gauge is provided on the main pipe. The vacuum pump is connected to a controller.

[0005] Furthermore, there are at least two blind hole groups, which are spaced apart along the length of the solder bath, and a support tube is inserted into each of the three blind holes in the blind hole group.

[0006] Furthermore, at least two sets of blind vias are evenly spaced along the width of the tin bath.

[0007] Furthermore, a mounting flange is fixedly connected to the upper end of the branch pipe on the lower side of the tin bath, and a sealing ring is provided on the upper side of the mounting flange. The mounting flange is fixedly connected to the mounting ring by bolts.

[0008] Furthermore, a cooling mechanism is provided below the solder bath on one side of the blind via group. The cooling mechanism includes a high-pressure jet pipe arranged along the length of the solder bath. Several high-pressure jet nozzles are evenly spaced on the upper part of the high-pressure jet pipe along its length. The high-pressure jet pipe is connected to a cooling fan through a connecting main pipe. The cooling fan is electrically connected to a controller.

[0009] Furthermore, an air-cooling mechanism is provided on the underside of the solder bath between each pair of blind via groups.

[0010] Furthermore, the diameter of the blind hole is 10mm.

[0011] Furthermore, the free end of the main pipe is connected to a gas storage tank, and the pumping end of the vacuum pump is connected to the gas storage tank.

[0012] The beneficial effects of this utility model are: 1. The present invention provides a bubble elimination device for the bottom of a tin bath. By opening blind holes of different depths for support pipes, guide pipes, main pipes and vacuum pumps, it can not only extract the gas at the bottom of the tin bath through blind holes of different depths, avoiding the gas rising due to untimely extraction and affecting glass production, thus achieving the purpose of eliminating bubbles, but also avoid the instability of the bottom of the tin bath after the device is disassembled by setting up support pipes. 2. The present invention provides a bubble elimination device for the bottom of a tin bath. By setting a wind-cooling mechanism on the lower surface of the tin bath, the device blows cold air onto the bottom of the tin bath through several high-pressure jet nozzles during the bubble elimination process, thereby cooling the bottom of the bath and slowing down the rising speed of the gas in the refractory bricks of the tin bath. This allows for more time to extract the gas, thus better preventing the gas from eventually forming bubbles and achieving the purpose of eliminating bubbles. 3.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] See Figs. 1-3 A bubble elimination device for the bottom of a tin bath includes a tin bath 1. At least one blind hole group 2 is formed along the length of the bottom surface of the tin bath 1. The blind hole group 2 consists of three blind holes with increasing depth from left to right. The diameter of each blind hole is 10 mm. A support tube 3 is inserted into the lower part of each blind hole. The blind holes have a trapezoidal structure. The diameter of the holes in the bottom steel plate of the tin bath is larger than the diameter of the refractory bricks in the tin bath. The support tube 3 is attached to the bottom steel plate and prevents instability to the bottom of the tin bath 1 after disassembly. The support tube 3 has several through holes 15 evenly spaced along its axial direction. The bottom surface of the tin bath 1 is fixedly connected to the support tube 3. The mounting ring 16 is coated with refractory adhesive between itself and the bottom surface of the tin bath 1 to ensure sealing. A branch pipe 17 is detachably connected to the lower end of the mounting ring 16. The branch pipe 17 is connected to a conduit 4, which is connected to the main pipe 5. The free end of the main pipe 5 is connected to a vacuum pump 6. A pressure gauge 7 is installed on the main pipe 5. The vacuum pump 6 is connected to a controller. Specifically, the controller controls the vacuum pump 6 to start, and the gas contained in the refractory bricks of the tin bath 1 can enter the support pipe 3 through several through holes 15 and finally be extracted from the branch pipe 17 to form a vacuum state, thus preventing the gas from rising into the tin bath 1 and forming bubbles, thereby achieving the purpose of eliminating bubbles.

[0019] The preferred blind hole group 2 is at least two groups. The specific number of groups can be determined according to the length of the high-temperature zone of the tin bath 1 and the area where bubbles are generated. When opening the blind holes, the length of the blind holes at both ends needs to be greater than the total length of the area where bubbles are generated. This allows for better and faster extraction of gas from the refractory bricks. The blind holes are distributed at intervals along the length of the tin bath 1. Support tubes 3 are inserted into the three blind holes of the blind hole group 2.

[0020] The preferred blind hole group 2 is arranged at least two groups evenly spaced along the width direction of the tin bath 1. This design can further increase the area for gas extraction and further ensure that all gas can be extracted.

[0021] The preferred tin bath 1 has a branch pipe 17 on the lower side with a fixed connection to the upper end of a mounting flange 8. The mounting flange 8 has a sealing ring 9 on its upper side. The mounting flange 8 is fixedly connected to the mounting ring 16 by bolts. This design is easy to disassemble and assemble, and convenient and quick to use.

[0022] A cooling mechanism is provided below the tin bath 1 on one side of the preferred blind hole group 2. The cooling mechanism includes a high-pressure jet pipe 10 arranged along the length of the tin bath 1. Several high-pressure jet nozzles 11 are evenly spaced on the upper part of the high-pressure jet pipe 10 along its length. The high-pressure jet pipe 10 is connected to a cooling fan 13 through a connecting main pipe 12. The cooling fan 13 is electrically connected to a controller. The design of the cooling mechanism allows it to blow cold air onto the bottom of the tin bath 1 through several high-pressure jet nozzles 11 during the process of eliminating bubbles, thereby cooling the bottom of the bath and slowing down the rising speed of the gas in the refractory bricks of the tin bath 1. This provides more time for gas extraction, better avoids the formation of bubbles, and improves the efficiency of bubble elimination.

[0023] The preferred method is to provide an air-cooling mechanism on the lower side of the tin bath 1 between the two blind hole groups 2.

[0024] Preferably, the diameter of the blind hole in this invention is 10mm.

[0025] The preferred main pipe 5 has its free end connected to a gas storage tank 14, and the vacuum pump 6 has its pumping end connected to the gas storage tank 14.

[0026] The working principle of this utility model is as follows: When evacuating the bottom of the tin bath 1 to prevent gas bubbles from forming and affecting the quality of float glass production, the controller starts the vacuum pump 6. The gas contained in the refractory bricks of the tin bath 1 can enter the support pipe 3 through several through holes 15, and finally be extracted from the branch pipe 17 to form a vacuum. At the same time, the controller's cold air blower 13 works to provide cold air to the connecting main pipe 12. The cold air is finally sprayed out from several high-pressure jet nozzles 11 to physically cool the bottom of the tin bath 1, slowing down the rising speed of the gas in the refractory bricks of the tin bath 1, giving more time to extract the gas, and preventing the gas from rising into the tin bath 1 and forming bubbles, thereby achieving the purpose of eliminating bubbles. The device has a simple structure, is easy to disassemble and assemble, has good defoaming performance, and is easy to master.
