[0018] The utility model will be further described below in combination with the drawings and embodiments.
[0019] Please refer to Figs. 1 to 4 A novel glass-melting furnace observation hole structure 1, comprising a pulley 11 (the pulley 11 is ingeniously installed below the glass-melting furnace's regenerator walkway to facilitate operation), a door seat 12 (stably installed on the glass-melting furnace) and a sealing door plate 13 flexibly connected to the door seat 12 through a hinge. One side of the door seat 12 ingeniously integrates an observation cylinder 14, and the end face of the observation cylinder 14 is carefully designed as an inclined shape to better adapt to the observation requirement. The sealing door plate 13 is in close contact with the end face of the observation cylinder 14, forming an effective seal.
[0020] On one side of the sealing door plate 13, a hanging ring 15 is firmly welded, and a steel wire rope 16 is wound and fixed on the hanging ring 15 (the steel wire rope 16 skillfully passes through the pulley 11 to form a labor-saving operation mechanism). On the side of the sealing door plate 13 opposite to the hanging ring 15, a convex part 17 is designed, which is tightly embedded in the inner side of the observation cylinder 14, further enhancing the sealing effect.
[0021] The door seat 12 is symmetrically provided with an ear plate 121, and one end of the sealing door plate 13 is also symmetrically provided with a connecting plate 131. The two sets of components are tightly hinged together by bolts, ensuring that the sealing door plate 13 can stably rotate on the door seat 12.
[0022] In actual operation, the operator only needs to easily pull the steel wire rope 16 to make the sealing door plate 13 smoothly rotate along the bolt hinge. Due to the skillful arrangement of the pulley 11, this operation process becomes extremely labor-saving. With the pulling of the steel wire rope 16, the sealing door plate 13 can be easily turned up to achieve the purpose of opening the sealing door plate 13. The opening degree of the sealing door plate 13 is accurately controlled by the distance of the operator pulling the steel wire rope 16.
[0023] When it is necessary to close the sealing door plate 13, the operator only needs to loosen the steel wire rope 16, and the sealing door plate 13 will automatically close under the action of its own gravity. During the closing process, the slight bumping of the sealing door plate 13 with the door seat 12 not only has no negative effect, but also can effectively reduce the enrichment of condensate through the generated vibration.
[0024] In addition, a firm welding connection is adopted between the hanging ring 15 and the sealing door plate 13, ensuring the stability and durability of the whole structure. The door seat 12 and the sealing door plate 13 are both made of high-silicon heat-resistant nodular cast iron RATAL5Si5, which has excellent high-temperature resistance and can well adapt to the high-temperature environment of the glass melting furnace.
[0025] Finally, the end face of the observation cylinder 14 is carefully designed to have an inclination angle of 20 degrees ± 1 degree with the door seat 12, which not only makes it more convenient and accurate to observe the glass melting furnace, but also further reduces the required effort when pulling the sealing door plate 13.
[0026] The above only describes the embodiments of the present application, and does not limit the patent range of the present application. Any equivalent structure or equivalent process conversion according to the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the present application.
