[0034] Embodiment 1

[0035] Please refer to Figures 1-7As shown in the figure, this embodiment provides a high-temperature tubular furnace flange feeding sealing device, which includes a base 1. A lower sealing chamber 11 is rotatably connected to the top of the base 1, and an upper sealing chamber 12 is rotatably connected to the top of the lower sealing chamber 11. A furnace tube 13 is arranged between the lower sealing chamber 11 and the upper sealing chamber 12. A transmission component 14 for rotating the furnace tube 13 is arranged on the outer wall of one end of the furnace tube 13. A sealing device 4 for automatically opening and closing the seal is arranged at one end of the furnace tube 13. A fixing component 41 for restricting the position of the sealing device 4 is arranged inside the sealing device 4. A rotating ring 44 is arranged inside the sealing device 4. Among them: Through the fixation of the fixing component 41, the sealing device 4 is used to complete the opening and closing of the furnace tube 13, and then the lower sealing chamber 11 and the rotating ring 44 are used to complete the opening and closing of the upper sealing chamber 12 at the same time.

[0036] As Figures 1-3 shown, a hydraulic rod is arranged inside the base 1, the upper end of the hydraulic rod is movably connected to the bottom of the lower sealing chamber 11, a controller 111 is arranged on the outer wall of the lower sealing chamber 11, and a first protection plate 112 and a second protection plate 113 are fixedly connected to both sides of the lower sealing chamber 11. A first telescopic rod 121 is fixedly connected to the outer wall of one side of the upper sealing chamber 12. An arc-shaped rod 122 is fixedly connected to the end of the first telescopic rod 121 far away from the upper sealing chamber 12. A first rack 123 is fixedly connected to the inner outer wall of the arc-shaped rod 122;

[0037] Among them, under the control of the controller 111, the hydraulic rod can be extended. At this time, the part above the lower sealing chamber 11 rotates upward, and the furnace tube 13 is inclined. The materials in the furnace tube 13 will all slide downward to the discharge port position and slide down when the sealing device 4 is automatically opened and collected.

[0038] As Figure 4 shown, a transmission component 14 is arranged on the outer wall of the furnace tube 13. The transmission component 14 includes a first gear 141. A second gear 142 is meshed with the bottom of the first gear 141. A rotating rod 143 is fixedly connected to the central position of one side of the second gear 142. A motor 144 is fixedly connected to the inside of the lower sealing chamber 11. The rotating rod 143 is fixedly connected to the output end of the motor 144. Among them: A first flange 2 is fixedly connected to one end of the furnace tube 13. A second flange 3 is bolted to one side of the furnace tube 13 of the first flange 2;

[0039] Among them, driven by the motor 144, the rotating rod 143 and the second gear 142 rotate together and drive the first gear 141 and the furnace tube 13 to rotate, which can ensure the turnover effect of the materials in the furnace tube 13 and make the heating effect better.

[0040] As Figures 5-7As shown, the sealing device 4 includes a fixing component 41. The fixing component 41 includes a first tripod 411, an outer tripod 413, and an inner disc 414. One side of the first tripod 411 is fixedly connected to a screw 412. The end of the screw 412 away from the first tripod 411 is fixedly connected to the outer tripod 413. There is an annular hole between the outer tripod 413 and the inner disc 414. The inner wall of the second guard plate 113 is fixedly connected to a rotating column 1131. The outer wall of the rotating column 1131 is fixedly connected to a turntable 42. The inner disc 414 is rotatably connected to the outer wall of the rotating column 1131. The outer tripod 413 is fixedly connected to a cross bar 4131 on the side away from the screw 412. The end of the cross bar 4131 away from the outer tripod 413 is fixedly connected to the inner wall of the second guard plate 113. One side of the turntable 42 is fixedly connected to a second telescopic rod 43. The second telescopic rod 43 passes through the annular hole. The end of the second telescopic rod 43 away from the turntable 42 is fixedly connected to a rotating ring 44. The outer wall of the rotating ring 44 is fixedly connected to a second rack 441. The second rack 441 is meshed and connected to the first rack 123. The inner wall of the rotating ring 44 is fixedly connected to an inner rack 442. One side of the rotating ring 44 is fixedly connected to a first blocking plate 443. The side of the rotating ring 44 away from the first blocking plate 443 is fixedly connected to a second blocking plate 444. The outer wall of the screw 412 is threadedly connected to a nut 415. The outer wall of the nut 415 is fixedly connected to a rack. The outer wall of the nut 415 is meshed and connected to the inner rack 442;

[0041] Among them, the first tripod 411 is sleeved on the outer wall of the first flange 2 and fixedly connected to the hexagon head at the hexagon head position of the screw 412, so that the hexagon head penetrates into the surface of the first tripod 411, and the other end of the screw 412 is fixed to the inner disc 414. Even if the rotating column 1131 rotates, it will not drive the inner disc 414 to rotate, but only drive the turntable 42 to rotate. When the turntable 42 rotates, it will also drive the second telescopic rod 43 to rotate, and the second telescopic rod 43 rotates along the annular hole between the outer tripod 413 and the inner disc 414.

[0042] It can be seen from this that when it is necessary to unload the materials in the furnace tube 13, as Figures 4-7 shown, the staff controls the motor 144 inside the rotating column 1131 through the controller 111 to drive the rotating column 1131 to rotate. At this time, during the rotation of the rotating column 1131, it will drive the turntable 42 to rotate together. At the same time, the second telescopic rod 43 on the turntable 42 rotates together, and drives the rotating ring 44 to rotate through the rotation of the second telescopic rod 43;

[0043] Under the rotation of the swivel ring 44, on the one hand, the second rack 441 on the outer wall drives the first rack 123 and the arc rod 122 to rotate upward, and drives the upper sealing chamber 12 to rotate upward through the first telescopic rod 121, and opens the lower sealing chamber 11 and the upper sealing chamber 12. At this time, the transparent furnace tube 13 is exposed outside, which can facilitate observing the heating condition of the material inside the furnace tube 13. Secondly, the outer wall of the furnace tube 13 can be appropriately cooled;

[0044] As Figure 5 shown, secondly, under the rotation of the swivel ring 44, on the other hand, the internal rack 442 on the inner wall drives the nut 415 to rotate. At this time, the screw 412 rotates to loosen the fixed state of the first flange 2 and the second flange 3. At this time, when the nut 415 rotates on the screw 412, it will move in the opposite direction of the second flange 3. At this time, the swivel ring 44 will move in the opposite direction of the second flange 3 together with the nut 415 under the restriction of the first blocking plate 443 on the nut 415. At the same time, under the restriction of the second blocking plate 444 on the second flange 3, the second flange 3 is also driven to move to the right together with the swivel ring 44, so that the first flange 2 and the second flange 3 are separated to form an opening, and the hydraulic rod is extended under the control of the controller 111, so that the upper part of the lower sealing chamber 11 is all inclined. At this time, the furnace tube 13 is inclined, forming an effect that the left side of the furnace tube 13 is high and the right side is low, and the material inside it all flows or slides towards the opened sealing device 4. This enables the sealing device 4 to automatically open or close the feeding position of the furnace tube 13, avoiding the staff from operating the screw 412 up and down, which is time-consuming and laborious;

[0045] As described above, conversely, when the furnace tube 13 is sealed after being loaded, the controller 111 can be operated to close the sealing device 4 in the same way;

[0046] It should be noted that when the inside of the furnace tube 13 needs to be cleaned, the hydraulic rod is used to lift the upper sealing chamber 12, and the staff disassembles and opens the screw 412 of the flange at the end far from the sealing device 4, and the sealing device 4 is opened under the control of the controller 111. At this time, the furnace tube 13 is taken out and the inside of the furnace tube 13 is rinsed;

[0047] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and do not limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
