Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] Reference Figure 1-6 A glass raw material melting observation window, comprising an observation window frame 1 and a refractory board 2, wherein two baffles 3 are connected to the top of the observation window frame 1, and the bottom surfaces of one end of the two baffles 3 are connected to a limited position semi-ring 4, and the top and bottom of one side wall of the observation window frame 1 are connected to a slide plate 5, a propulsion assembly is arranged in the slide plate 5, and the end surface of the refractory board 2 is connected to a heat insulation board 12;

[0026] Further, the top of the observation window frame 1 is fixedly connected to the bottom end of the baffle plate 3, the bottom surface of one end of the baffle plate 3 is fixedly connected to the outer side wall of the top of the limiting semi-ring 4, the inner side wall of the limiting semi-ring 4 is slidably connected to the side wall of the top of the T-shaped piston rod 18, the end of the slide rail plate 5 is fixedly connected to the side wall of the observation window frame 1, and the propulsion assembly is composed of a telescopic rod 6, a compression spring 7 and a push plate 8, the compression spring 7 is arranged on the outer side wall of the telescopic rod 6, the fixed end of the telescopic rod 6 is fixedly connected to the inner side wall of the slide rail plate 5, the movable end of the telescopic rod 6 is fixedly connected to the side wall of the push plate 8, the two ends of the compression spring 7 are respectively fixedly connected to the side walls of the telescopic rod 6 and the push plate 8, the inner side wall of the slide rail plate 5 is slidably connected with a rotating shaft 9, the outer side wall of the rotating shaft 9 is fixedly connected with a rotating plate 10, the side wall of the rotating plate 10 is fixedly connected with a fixed plate 11, the side wall of the fixed plate 11 is fixedly connected to the side wall of the heat insulation plate 12, and the inner side wall of the heat insulation plate 12 is fixedly connected with a sealing ring plate 13;

[0027] It should be noted that: the observation window frame 1 is installed in the observation hole on the kiln, and then when it is necessary to observe the situation inside the kiln, the limit rod 16 is pulled out from the plug plate 15 and the limit plate 14 to release the limit. After the limit is released, the compression spring 7 will stretch the telescopic rod 6, and the telescopic rod 6 will push the push plate 8 to move, and the push plate 8 will push the rotating shaft 9 to slide to the end on the slide plate 5, and then the pull plate 17 at the other end of the limit rod 16 is passed through the pull hole on the limit plate 14 and rotated to a certain angle for limiting. Pulling the limit rod 16 will allow the rotating plate 10 connected to the heat insulation plate 12 to rotate on the rotating shaft 9;

[0028] A further advantage of adopting the above method is that it is convenient to observe the firing conditions in the kiln, avoiding direct contact between the observer and the shielding components, thereby ensuring the safety of the observation operation.

[0029] A limit plate 14 is fixedly connected to one side wall of the heat insulation board 12, a plug plate 15 is arranged below the limit plate 14, a limit rod 16 is arranged on the plug plate 15, a pull plate 17 is fixedly connected to the end of the limit rod 16, a T-shaped piston rod 18 is arranged on one side of the heat insulation board 12, a right angle tube 21 is connected to the outer side wall of the T-shaped piston rod 18, a push-suction assembly is arranged in the right angle tube 21, and a round bucket 22 is arranged on one side of the push-suction assembly;

[0030] Furthermore, the top and side walls of the limiting plate 14 are respectively provided with limiting holes and pulling holes, the inner side wall of the limiting hole is slidably connected to the outer side wall of the limiting rod 16, a slot is provided on the plug plate 15, and the slot is adapted to the limiting rod 16, the side wall of the plug plate 15 is fixedly connected to the side wall of the observation window frame 1, and the pulling plate 17 is adapted to the pulling hole, and the push-suction assembly is composed of a piston plate 19 and a return spring 20, the top of the piston plate 19 is fixedly connected to the bottom end of the T-shaped piston rod 18, the return spring 20 is arranged on the outer side wall of the T-shaped piston rod 18, the two ends of the return spring 20 are respectively fixedly connected to the inner bottom side wall of the right-angle tube 21 and the top of the piston plate 19, the side wall of the piston plate 19 is slidably connected to the inner side wall of the right-angle tube 21, a circular hole is provided at the top of the right-angle tube 21, and the inner side wall of the circular hole is slidably connected to the side wall of the T-shaped piston rod 18, the other end of the right-angle tube 21 is fixedly connected to the end of the round bucket 22, and the other end of the round bucket 22 is fixedly connected with a filter plate 23;

[0031] It should be noted that: the heat insulation board 12 will drive the right-angle tube 21 and the T-shaped piston rod 18 to move during the outward sliding process. After the sliding is completed, the T-shaped piston rod 18 will be separated from the limit of the upper limit semi-ring 4 of the baffle 3, and the piston plate 19 will quickly slide upward under the elastic force of the return spring 20, so that the right-angle tube 21 is instantly in a negative pressure state, and the hot air flow in the kiln is quickly sucked in. When the refractory board 2 is opened, an outward hot air flow will be formed, pushing away the air outside the observation hole, so as to avoid a large amount of air entering the kiln when opening, causing oxidation of the glass raw materials;

[0032] A further advantage of adopting the above method is that when the refractory board 2 is opened, the air outside the observation hole can be pushed away, which is convenient for the observer to conduct a brief observation and avoids a large amount of air entering the kiln during the observation to cause oxidation of the glass raw materials and affect the quality of the glass.

[0033] When the utility model is in use, the observation window frame 1 is installed in the observation hole on the kiln. When it is necessary to observe the situation in the kiln, the limit rod 16 is pulled out from the plug plate 15 and the limit plate 14 to release the limit. After the limit is released, the compression spring 7 will stretch the telescopic rod 6, and the telescopic rod 6 will push the push plate 8 to move, and the push plate 8 will push the rotating shaft 9 to slide on the slide rail plate 5 to the end, and then the pulling plate 17 at the other end of the limit rod 16 passes through the pulling hole on the limit plate 14 and rotates a certain angle for limiting. Pulling the limit rod 16 will allow the rotating plate 10 connected to the insulation plate 12 to rotate on the rotating shaft 9, which can facilitate the observation of the firing situation in the kiln, avoid direct contact between the observer and the shielding component, and ensure the safety of the observation operation;

[0034] When the heat insulation board 12 slides outward, it will drive the right-angle tube 21 and the T-shaped piston rod 18 to move. After the sliding is completed, the T-shaped piston rod 18 will be separated from the limit of the upper limit semi-ring 4 of the baffle 3, and the piston plate 19 will quickly slide upward under the elastic force of the return spring 20, so that the right-angle tube 21 is instantly in a negative pressure state, and the hot air flow in the kiln is quickly sucked in. The filter plate 23 can prevent impurities and dust from being sucked in. Therefore, when the refractory board 2 is opened, an outward hot air flow will be formed, pushing away the air outside the observation hole, avoiding a large amount of air entering the kiln when opening, causing oxidation of the glass raw materials. In this way, the air outside the observation hole can be pushed away when the refractory board 2 is opened, which is convenient for observers to conduct short observations, and avoiding a large amount of air entering the kiln during observation to oxidize the glass raw materials and affect the quality of the glass.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
