[0030] The techniques, methods, and devices known to those skilled in the relevant art can not be discussed in detail, but in appropriate cases, the techniques, methods, and devices should be considered as part of the specification.

[0031] As Figures 1-6 shown, the utility model provides a high temperature furnace open and close structure, include: furnace body 1, furnace body 1 is set up furnace mouth 101 on, furnace door 2 can close furnace mouth 101, sliding chute 3, sliding chute 3 is installed on the outer surface of furnace body 1, wherein, furnace door 2 can be slidably installed in sliding chute 3, so that furnace door 2 has the first state of closing furnace mouth 101 and the second state of at least partially opening furnace mouth 101.

[0032] Specifically, the sliding chute 3 is fixed on the furnace body 1, and the extension direction thereof is parallel to the surface of the furnace body 1. The furnace door 2 reciprocates in the sliding chute 3 parallel to the surface of the furnace body 1, effectively reducing the space occupied by the furnace door 2 during opening and closing. Figure 1 and Figure 2 As shown in the drawings, the furnace mouth 101 is located at the end of the extension direction of the sliding chute 3, and the end is closed, so that the furnace door 2 enters the first state when moving to the closed end in the sliding chute 3, facilitating the closing of the furnace mouth 101 by the staff.

[0033] During production, the staff adjusts the position of the furnace door 2 in the sliding chute 3 to adjust the opening area of the furnace mouth 101 according to the different sizes of the materials entering and exiting the furnace mouth 101, avoiding excessive opening that leads to rapid heat loss in the furnace, and effectively improving the production efficiency of the high-temperature furnace.

[0034] As Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, a linkage component 4 is also included. The linkage component 4 includes a first connecting rod 401 and a second connecting rod 402. The first end of the first connecting rod 401 and the first end of the second connecting rod 402 are rotatably connected. The second end of the first connecting rod 401 is rotatably connected to the furnace body 1, and the second end of the second connecting rod 402 is rotatably connected to the furnace door 2.

[0035] Specifically, when it is necessary to adjust the position of the furnace door 2 within the slide groove 3, the operator can indirectly adjust the position of the furnace door 2 within the slide groove 3 through the linkage component 4 to avoid direct contact with the furnace door 2 and resulting in burns. Specifically, the operator can drive the first connecting rod 401 to rotate relative to the furnace body 1, thereby moving the second connecting rod 402 to adjust the position of the furnace door 2 connected to the second connecting rod 402 within the slide groove 3. Alternatively, the position of the furnace door 2 within the slide groove 3 can be adjusted by pulling the connection between the first connecting rod 401 and the second connecting rod 402.

[0036] In other embodiments, the furnace door 2 can also be moved by other common driving components such as cylinders or electric actuators installed on the surface of the furnace body 1 and connected to the furnace door 2, so as to reduce manual operation and improve equipment safety.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the linkage component 4 further includes a first hinge seat 403 fixedly installed on the furnace body 1 and a second hinge seat 404 fixedly installed on the furnace door 2; wherein, the first connecting rod 401 is hingedly connected to the first hinge seat 403, and the second connecting rod 402 is hingedly connected to the second hinge seat 404.

[0038] Specifically, the extension direction of the slide groove 3 is arranged in a straight line, and the first hinge seat 403 and the second hinge seat 404 are respectively installed on the furnace body 1 and the furnace door 2 along the extension direction of the slide groove 3, which restricts the rotation and translation of the first connecting rod 401 and the second connecting rod 402 to a single plane, effectively improving the stability of the linkage component 4 during the movement.

[0039] In some embodiments, the high-temperature furnace opening and closing structure further includes a drive member for driving the first connecting rod 401 to rotate about the first hinge seat 403.

[0040] Specifically, the first hinged seat 403 comprises a base fixedly connected with the furnace body 1 and a rotating shaft rotatably arranged on the base, and the end of the first connecting rod 401 is fixedly connected with the rotating shaft. The driving member drives the rotating shaft to rotate relative to the base, so as to drive the first connecting rod 401 to rotate relative to the first hinged seat 403, thereby adjusting the position of the furnace door 2 in the sliding groove 3. When the furnace door 2 is in the first state, the driving member retains a certain driving force, and drives the furnace door 2 to tightly abut on the closed end of the sliding groove 3, so as to ensure the sealing fit between the furnace door 2 and the furnace body 1. The driving member can be a conventional driving member such as a motor or a hydraulic motor.

[0041] As shown in Figure 4 , Figure 5 and Figure 6 , in some embodiments, the furnace door 2 comprises a sliding part 201 and a sealing part 202. The furnace door 2 is movably installed in the sliding groove 3 through the sliding part 201, and can be sealingly connected with the furnace opening 101 through the sealing part 202.

[0042] Specifically, the part of the furnace door 2 far away from the furnace body 1 is the sliding part 201, and the part close to the furnace body 1 is the sealing part 202. The size of the sliding part 201 is greater than that of the sealing part 202, and the protruding part is the part matched with the sliding groove 3. The furnace door 2 can move back and forth in the sliding groove 3 through the sliding part 201. When the furnace door 2 is in the first state, the sealing part 202 can be embedded in the furnace opening 101, thereby improving the sealing effect between the furnace door 2 and the furnace body 1.

[0043] As shown in Figure 4 , Figure 5 and Figure 6 , in some embodiments, the edge of the sealing part 202 is chamfered, and the edge of the furnace opening 101 is provided with a slope matched with the chamfer.

[0044] Specifically, in order to make the sealing part 202 of the furnace door 2 more conveniently slide into the furnace opening 101 to complete the embedding therebetween during the reciprocating sliding of the furnace door 2 in the sliding groove 3, the edge of the sealing part 202 is chamfered, and a corresponding slope is arranged at the edge of the furnace opening 101, so as to avoid the jamming of the furnace door 2 during the sliding process.

[0045] As shown in Figure 1 , Figure 2 and Figure 3 , in some embodiments, the sliding groove 3 comprises a sealing section 301, a slope section 302 and an opening section 303 arranged in sequence along the extending direction. The two ends of the slope section 302 connect the sealing section 301 and the opening section 303, and the opening section 303 is arranged at one end of the slope section 302 away from the furnace opening 101. In the second state, the furnace door 2 can slide along the slope section 302 to adjust the opening area of the furnace opening 101.

[0046] Specifically, in the first state, the furnace door 2 is located in the sealing section 301 of the chute 3, at this time, the furnace door 2 is connected with the furnace body 1 by the sealing part 202 embedded in the furnace opening 101. When the worker drives the furnace door 2 to move along the chute 3 into the second state through the linkage assembly 4, the furnace door 2 slides along the slope section 302 to the opening section 303 side through the sliding part 201, as shown in the figure, the second connecting rod 402 exerts an obliquely upward force on the furnace door 2, driving the furnace door 2 to move along the slope section 302, based on the setting of the slope section 302, the furnace door 2 gradually moves away from the furnace body 1 in the vertical direction during the sliding process, and at the same time, by using the cooperation between the chamfer of the edge of the sealing part 202 of the furnace door 2 and the slope of the edge of the furnace opening 101, the sealing part 202 can smoothly slide out of the furnace opening 101, and the embedded cooperation between the two is released, so that the furnace door 2 can smoothly enter the second state and can complete the adjustment of the opening area of the furnace opening 101. Figure 3

[0047] In some embodiments, the surface of the sealing part 202 is provided with a refractory layer. Specifically, the refractory layer provided on the surface of the sealing part 202 can effectively increase the service life of the furnace door 2 and enhance the heat preservation effect of the furnace door 2. The refractory layer can be made of aluminum silicate fiber material or high-aluminum castable material, which can withstand high temperature in the furnace.

[0048] As shown in the figure, in some embodiments, the position where the sealing part 202 contacts the furnace opening 101 is provided with a sealing element 203. Figure 4

[0049] Specifically, the sealing element 203 can be a glass fiber elastic sealing rope arranged at the connection position of the sliding part 201 and the sealing part 202, so that the connection position of the sliding part 201 and the sealing part 202 can form a smooth transition, and by using the sealing effect of the sealing element 203 and the elasticity thereof, the sealing property and the heat preservation effect of the furnace door 2 in the first state can be effectively improved. In other embodiments, the sealing element 203 can also use common high-temperature-resistant sealing elements such as asbestos rubber gasket or high-temperature silicone pad, so as to improve the sealing effect between the furnace door 2 and the furnace body 1.

[0050] The present disclosure also provides a high-temperature furnace provided with the high-temperature furnace opening and closing structure described above. In the production process, the worker can adjust the opening area of the furnace opening 101 according to the size of the glass in the high-temperature furnace, so as to effectively reduce the heat loss in the furnace caused by opening and closing the furnace door 2, shorten the time for restoring the steady-state temperature field in the furnace, and improve the production efficiency of the glass.
