Description

Technical Field

[0001] This utility model relates to the field of glass production equipment technology, and in particular to a bottom cooling device for a glass kiln. Background Technology

[0002] In float glass production, the glass furnace is one of the three major thermal equipment and plays an extremely important role. The furnace is in a high-temperature baking state for a long time, and the molten glass washes and erodes the bottom of the furnace pool at different rates depending on the temperature of the bottom pool. When the bottom temperature is low, the degree of erosion of the bottom pool by the molten glass is reduced, which can maintain the stable operation of the furnace for a long time.

[0003] However, after decades of operation, the bottom bricks of the glass kiln have shown varying degrees of erosion and a reddish tinge. The thinning of the eroded bricks poses a risk of leakage. Therefore, a cooling device for the bottom of the glass kiln is proposed to address these issues. Utility Model Content

[0004] The purpose of this application is to provide a bottom cooling device for a glass furnace to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a glass furnace bottom cooling device, including a cooling fan;

[0006] A support plate is arranged parallel to the lower side of the glass furnace and installed on the support legs used to support the glass furnace.

[0007] The air duct is installed on the upper end of the support plate, and one end of the air duct is connected to the air outlet of the cooling fan.

[0008] The cooling air ducts are arranged in multiples and are vertically fixed and connected to the air duct at equal intervals.

[0009] As a further supplement to this solution, multiple heat dissipation strips are also included, which are fixed at equal intervals along the length of the glass furnace on the bottom outer wall of the glass furnace.

[0010] As a further supplement to this solution, the support plate is vertically slidably sleeved on the support leg, and the bottom end of the support leg is fixed with a mounting bracket. The mounting bracket is equipped with a lifting drive assembly connected to the support plate to drive the support plate to slide up and down along the support leg.

[0011] A flexible hose is fixedly connected between the air duct and the air outlet of the cooling fan.

[0012] As a further supplement to this solution, the lifting drive assembly includes a drive motor and a threaded rod. The drive motor is fixed on the mounting bracket, and one end of the threaded rod is coaxially fixed with the output end of the drive motor. The vertical thread of the threaded rod passes through the support plate.

[0013] As a further supplement to this solution, the support plate is densely covered with heat dissipation holes.

[0014] As a further supplement to this solution, a fixing plate is installed on the support leg, and multiple unblocking columns are fixed at the upper end of the fixing plate. The multiple unblocking columns correspond vertically to multiple heat dissipation holes, and the diameter of the unblocking columns is consistent with the diameter of the heat dissipation holes.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. In this utility model, by coordinating a cooling fan, a support plate, an exhaust pipe, and cooling ducts, the cooling fan delivers air to multiple cooling ducts through the exhaust pipe to cool the bottom of the glass furnace. Combined with heat dissipation strips installed on the outer wall of the bottom of the glass furnace, this enhances the cooling of localized pool wall bricks. The molten glass in this area solidifies after cooling, forming a protective layer at the bottom of the pool, preventing leakage due to the thinning of the bottom bricks caused by erosion. Furthermore, the degree of localized cooling can be controlled via PLC, allowing adjustment of airflow and pressure using conventional techniques to reduce glass defects caused by bottom cooling air and achieve a balance between bottom cooling and glass quality.

[0017] 2. In this utility model, by setting up the lifting drive component, when installing the air duct and cooling air duct, the lifting drive component can be used to lower the support plate to close to the ground, so that the staff does not need to climb to operate, which is more convenient and safer. After the installation is completed, the lifting drive component can be used to move the support plate up to the top of the cooling air duct and close to the bottom of the glass furnace, so only a shorter cooling air duct needs to be set.

[0018] 3. In this utility model, a fixing plate is installed on the support leg, and multiple unblocking columns are fixed at the upper end of the fixing plate. The multiple unblocking columns are vertically aligned with multiple heat dissipation holes, and the diameter of the unblocking columns is consistent with the diameter of the heat dissipation holes. The staff can periodically use the lifting drive component to drive the support plate down, so that the unblocking columns can unblock the heat dissipation holes from bottom to top, ensuring the stable heat dissipation function of the heat dissipation holes.

[0024] 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.

[0025] Example 1: Reference Figure 1-2 The glass furnace bottom cooling device shown includes a cooling fan 3, a support plate 4, an air duct 5 and a cooling duct 6, and also includes multiple heat dissipation strips 11.

[0026] The exhaust duct 5 is made of multiple welded steel pipes, and the cooling fan 3 is a variable frequency fan, which makes it easy to adjust the air volume. A temperature sensor (not shown in the figure) can be added to the bottom of the glass furnace 1 to monitor the temperature at the bottom of the glass furnace 1 in real time, and work with the cooling fan 3 to achieve real-time adjustment of the temperature at the bottom of the furnace.

[0027] Specifically, the support plate 4 is arranged parallel to the lower side of the glass furnace 1 and installed on the support leg 2 used to support the glass furnace 1. The air duct 5 is installed on the upper end of the support plate 4, and one end of the air duct 5 is connected to the air outlet of the cooling fan 3. Multiple cooling air ducts 6 are provided, and the cooling air ducts 6 are vertically fixed and connected to the air duct 5 at equal intervals. Multiple heat dissipation strips 11 are fixed at equal intervals along the length direction of the glass furnace 1 on the bottom outer wall of the glass furnace 1.

[0028] By using the cooling fan 3 to send air to multiple cooling air ducts 6 through the air duct 5, the bottom of the glass furnace 1 is cooled by air. In conjunction with the heat dissipation strips 11 set on the bottom outer wall of the glass furnace 1, the cooling of the local pool wall bricks can be enhanced. After the glass liquid in this part is cooled and solidified, it serves as a protective layer for the bottom of the pool, avoiding the risk of leakage caused by the bottom bricks becoming thinner due to erosion.

[0029] When put into use, the degree of local cooling can be controlled by PLC. The air volume and air pressure can be adjusted according to conventional technical means in this field to reduce glass defects caused by bottom cooling air and achieve a balance between bottom cooling and glass quality.

[0030] Example 2: Reference Figure 3 The glass furnace bottom cooling device shown differs from Embodiment 1 in that, since the bottom of the glass furnace 1 is 8 meters above the ground (to ensure stable heat dissipation at its bottom and coordination with other equipment), workers generally need to climb to the top of the support plate 4 to install the exhaust pipe 5 and cooling pipe 6. Due to the height, the installation is cumbersome and poses certain safety hazards. If the exhaust pipe 5 and cooling pipe 6 are installed closer to the ground, a longer cooling pipe 6 is required, resulting in material waste. To solve the above problems, this embodiment vertically slides the support plate 4 onto the support leg 2. A mounting frame is fixed at the bottom of the support leg 2, and a lifting drive assembly connected to the support plate 4 is installed on the mounting frame to drive the support plate 4 to slide up and down along the support leg 2. A flexible hose 12 is fixedly connected between the exhaust pipe 5 and the air outlet of the cooling fan 3.

[0031] When installing the exhaust duct 5 and cooling duct 6, the support plate 4 can be lowered to close to the ground using the lifting drive assembly, so that the staff does not need to climb to operate, which is more convenient and safer. After installation, the support plate 4 can be moved up to the top of the cooling duct 6 and close to the bottom of the glass furnace 1 using the lifting drive assembly, so that only a shorter cooling duct 6 needs to be installed.

[0032] The lifting drive assembly includes a drive motor 7 and a threaded rod 8. The drive motor 7 is fixed on the mounting bracket, and one end of the threaded rod 8 is coaxially fixed with the output end of the drive motor 7. The threaded rod 8 has a vertical thread that passes through the support plate 4.

[0033] In order to dissipate the heat at the bottom of the glass furnace 1 quickly, the support plate 4 is covered with heat dissipation holes 401.

[0034] Considering that after prolonged use, the support plate 4 will accumulate a lot of dust, causing the heat dissipation holes 401 to become clogged and difficult to clean, this embodiment installs a fixing plate 9 on the support leg 2. Multiple unblocking columns 10 are fixed to the upper end of the fixing plate 9, and the multiple unblocking columns 10 are vertically aligned with the multiple heat dissipation holes 401. The diameter of the unblocking column 10 is consistent with the diameter of the heat dissipation hole 401. The operator can periodically use the lifting drive component to drive the support plate 4 downward, so that the unblocking column 10 can unblock the heat dissipation holes 401 from bottom to top.

[0035] 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.
