[0033] Referring to Figure 1 as shown, the present utility model provides a technical solution: a hot-state variable melting pool structure for a glass furnace, including a glass furnace bottom 1, and a glass furnace sidewall 2 is installed on the peripheral surface of the glass furnace bottom 1;

[0034] Electrode brick mounting holes 3 are opened on the surface of the glass furnace sidewall 2;

[0035] A glass liquid baffle 4 has its surface slidably penetrating through the surface of the glass furnace sidewall 2;

[0036] A fixing mechanism 5 is located on one side surface of the glass liquid baffle 4; and

[0037] A measuring mechanism 6 is located on the side of the glass liquid baffle 4 away from the fixing mechanism 5.

[0038] Next, the specific settings and functions of the fixing mechanism 5 and the measuring mechanism 6 will be specifically described.

[0039] Referring to Figure 2 、 Figure 3 and Figure 4 as shown, in this embodiment: The fixing mechanism 5 includes a fixing plate 51, one end of the fixing plate 51 is fixedly connected to the surface of the glass furnace sidewall 2, a toothed groove 53 is opened on the surface of the fixing plate 51, a sliding frame 52 is fixedly connected to one side surface of the glass liquid baffle 4, the inner wall of the sliding frame 52 slidably penetrates through the surface of the fixing plate 51, a connecting frame 54 is fixedly connected to the surface of the sliding frame 52, a moving rod 56 slidably penetrates through the surface of the connecting frame 54, a clamping plate 55 is fixedly connected to the end of the moving rod 56 close to the glass liquid baffle 4, the cross-section of the clamping plate 55 is in the shape of a tapered tooth, and the surface of the clamping plate 55 is engaged with the inner wall of the toothed groove 53. The measuring mechanism 6 includes a connecting plate 61, one end of the connecting plate 61 is fixedly connected to the surface of the glass furnace sidewall 2, a sliding groove 68 is opened on the upper surface of the connecting plate 61, a moving plate 62 is slidably connected to the inner wall of the sliding groove 68, an indicating plate 66 is fixedly connected to the side wall of the moving plate 62, and a scale 67 is provided on the side wall surface of the connecting plate 61.

[0040] When regulating the spatial structure inside the glass furnace, it is necessary to assist the operation by means of the glass liquid baffle 4 that slides through the surface of the glass furnace sidewall 2, and at the same time, assist the operation by means of the fixing mechanism 5. By allowing the glass liquid baffle 4 to slide along the fixing plate 51 with the sliding frame 52 on one side, and at the same time, the moving rod 56 on the surface of the sliding frame 52 drives the clamping plate 55 to be clamped and limited with the tooth groove 53 opened on the surface of the fixing plate 51, so as to effectively facilitate the sliding limit of the position of the glass liquid baffle 4. At the same time, one side of the glass liquid baffle 4 is provided with a connecting plate 61, and the moving length of the glass liquid baffle 4 is measured by means of the scale 67 provided on the surface, which is convenient for regulating the space inside the entire glass furnace tank.

[0041] The fixing mechanism 5 further includes a spring 57. The two ends of the spring 57 are respectively fixedly connected to the moving rod 56 and the connecting frame 54. Through the tensile force generated by the spring 57, the position of the moving rod 56 can be extruded and limited. One end of the moving rod 56 away from the clamping plate 55 is rotatably connected with a pull ring 58. When moving the position of the moving rod 56, the pull ring 58 can be used for auxiliary operation. The length dimension of the pull ring 58 is adapted to the cross-sectional dimension of the moving rod 56. Two guiding blocks 59 are fixedly connected to the surface of the glass furnace sidewall 2 corresponding to the position of the glass liquid baffle 4. When sliding the position of the glass liquid baffle 4, a guiding frame can be used for auxiliary guiding and limiting. The two guiding blocks 59 are respectively located at both ends of the glass liquid baffle 4. The cross-section of the guiding block 59 is in a "U" shape, and the inner wall of the guiding block 59 is slidably connected to the side wall of the glass liquid baffle 4.

[0042] The measuring mechanism 6 further includes an extrusion rod 63. One end of the extrusion rod 63 close to the glass liquid baffle 4 is fixedly connected with an extrusion pad 65. The extrusion pad 65 is a rubber pad. By means of the extrusion pad 65 at the upper end of the moving plate 62, the friction can be increased, which is convenient for temporarily positioning the position of the glass liquid baffle 4. A tension spring 64 is sleeved on the arc surface of the extrusion rod 63. The two ends of the tension spring 64 are respectively fixedly connected to the extrusion rod 63 and the moving plate 62. Through the extrusion force generated by the tension spring 64, the extrusion pad 65 can be better extruded and limited. The bottom end cross-section of the indicating plate 66 is in a tapered shape. The length dimension of the indicating plate 66 is adapted to the size of the scale 67. The indicating plate 66 can visually observe the value of the scale 67. The moving plate 62 is a hard alloy frame, and the cross-section of the moving plate 62 is in an "L" shape.

[0043] When building a kiln, first build the multi-layer bottom 1 of the glass kiln. The sidewall 2 of the glass kiln is built around the periphery of the bottom 1 of the glass kiln, forming a glass melting pool in the middle. When building the sidewall 2 of the glass kiln, reserved holes 3 for installing electrode bricks are provided. At the same time, when building the sidewall 2 of the glass kiln, two installation holes for the glass liquid baffle 4 are reserved on each side. The glass liquid baffle 4 can move freely in the front and back directions to adjust the hot glass liquid flow. The material of the glass liquid baffle 4 is the same as that of the sidewall 2 of the glass kiln, and the installation distance is at the middle position between the two electrode brick installation holes 3, minimizing the erosion of the electrode bricks on the glass liquid baffle 4. During the process adjustment, the glass liquid baffle 4 is manually pushed into the kiln to divide the melting pool space of the kiln, slowing down the flow rate of the harmful glass liquid. After the glass liquid state is stabilized in cooperation with the kiln central control room, the glass liquid baffle 4 is manually withdrawn to start normal production.

[0044] During normal production of the production line, the glass liquid baffle 4 is located outside the melting pool and will not cause any impact on production. Moreover, its material is the same as that of the sidewall 2 of the glass kiln, and no refractory material defects will be introduced. During the early and late stages of production when the state of the kiln glass liquid is most likely to change, using the glass liquid baffle 4 can change the structure of the hot glass kiln, change the flow state of the glass liquid without increasing the overall energy input of the kiln, and accelerate the process adjustment rate, achieving the purpose of reducing the operating cost of the production line.
