Description

Technical Field

[0001] This invention relates to the field of metallurgical experimental technology. Specifically, it relates to a tube furnace for heat treatment of terahertz materials. Background Technology

[0002] For example, Chinese Patent No. CN113203285B discloses a tubular furnace device and its usage method that facilitates material feeding during production. The device consists of a vacuum system, a furnace body, a furnace tube, a crucible, a ventilation / feeding channel, and a lifting system. The vacuum system includes a sealed furnace cover, an extraction pipe, and a vacuum pump. The sealed furnace cover is located on the upper part of the furnace body, and the top of the sealed furnace cover is connected to one end of the extraction pipe, while the other end of the extraction pipe is connected to the vacuum pump.

[0003] In this method, the material is fed into the furnace body through the feeding channel under negative pressure. During the feeding process, the feeding channel remains open for a period of time after the material passes through it. During this time, the heat inside the furnace body will pass through the feeding channel, which will still cause some heat loss. In addition, the material will accumulate in one place after feeding, which will affect the material utilization efficiency. To address this problem, we propose a terahertz material heat treatment tube furnace. Summary of the Invention

[0011] In the aforementioned terahertz material heat treatment tube furnace, the second fixed plate is connected to the right sealing plate via a connecting rod. The inner wall of the feeding cylinder is provided with a transmission groove, and a rotating gear is rotatably connected in the transmission groove. Moving rods are fixedly connected to both sealing plates, and moving racks are provided on opposite sides of the two moving rods. Both moving racks are meshed with the rotating gear.

Detailed Implementation

[0030] See attached document Figure 1-2 A terahertz material heat treatment tube furnace includes a furnace body 1 and a feeding cylinder 2. The furnace body 1 is characterized by having a feeding port 3, and a transmission cavity is provided on one side of the feeding port 3. An electric push rod 17 and a transmission rack 18 are provided in the transmission cavity. The output end of the electric push rod 17 is fixedly connected to a push rod, and the push rod is fixedly connected to the feeding cylinder 2. The electric push rod 17 controls the push rod to move up and down. The electric push rod 17 is existing technology and will not be described in detail here.

[0031] See attached document Figure 3 and Figure 6 A transmission gear 28 is fixedly connected to the outer wall of the rotating shaft 8 located outside the feeding cylinder 2. The transmission gear 28 is meshed with the transmission rack 18. The outer wall of the rotating shaft 8 located inside the feeding cylinder 2 is threadedly connected to the moving block 10. The moving block 10 is fixedly connected to the second fixed plate 9 by a fixed rod. During the downward movement of the feeding cylinder 2, the rotating shaft 8 will rotate, and the moving block 10 will move under the action of the thread. Thus, the top of the feeding cylinder 2 can be closed during the downward movement of the feeding cylinder 2 without the need for the operator to manually close it.

[0032] The feed inlet 3 is connected to the interior of the furnace body 1. The feeding cylinder 2 is slidably connected to the inner wall of the feed inlet 3. A fixed plate 16 is fixedly connected to one side of the bottom end of the feed inlet 3. Two symmetrically arranged material rollers 21 are provided below the fixed plate 16. A sliding groove 20 is provided between the feed inlet 3 and the fixed plate 16. A reset block 24 is provided at the bottom end of the sliding groove 20. A reset spring 22 is provided between the reset block 24 and the inner wall of the sliding groove 20. An installation shaft is rotatably connected to the inner wall of the furnace body 1. An installation gear 23 is fixedly connected to the outer wall of the installation shaft. An installation rack 23 is fixedly connected to the bottom of the reset block 24. The installation gear 23 and the installation rack 23 are meshed. A stirring rod is fixedly connected to the installation shaft. The two material rollers 21 are fixedly connected to the two ends of the stirring rod respectively.

[0033] Reference Figure 8 An energy storage mechanism is rotatably connected to the fixed plate 16. The energy storage mechanism consists of two energy storage plates and one energy storage spring 19. The two energy storage plates are respectively located at both ends of the two energy storage springs 19. A sliding block is slidably connected in the sliding groove 20. The sliding block is slidably connected to the feeding cylinder 2. The two energy storage plates are rotatably connected to the fixed plate 16 and the sliding block, respectively. The spring constant of the energy storage spring 19 is greater than that of the return spring 22. During the downward movement of the feeding cylinder 2, the energy storage spring 19 will be compressed. When the feeding cylinder 2 moves to the bottom of the feed inlet 3, the top of the energy storage spring 19 also moves to the bottom of the sliding groove 20, and at the same time, the stiffness coefficient accumulated by the energy storage spring 19 is released. Since the stiffness coefficient of the energy storage spring 19 is greater than that of the return spring 22, the return spring 22 will be compressed. During this process, the two material dispersing rollers 21 will rotate, and the material will also be poured down, which will disperse the poured material and make it dispersed to the bottom of the furnace body 1.

[0034] Reference Figures 11-12 A telescopic plate is provided above the feeding cylinder 2. The telescopic plate is composed of a first fixed plate 4 and a second fixed plate 9. The first fixed plate 4 is fixedly connected to the top of the feeding cylinder 2. The second fixed plate 9 is connected to the first fixed plate 4 by insertion. Two symmetrically arranged sliding shafts are fixedly connected to the bottom of the feeding cylinder 2. Sliding holes are opened on both sealing plates 5. The outer wall of the sliding shaft is directly slidably connected to the inner wall of the sliding hole. When the feeding cylinder 2 is located at the top of the feed inlet 3, the second fixed plate 9 is inside the first fixed plate 4, and the two sealing plates 5 are in contact with each other and seal the bottom of the feeding cylinder 2, thereby ensuring that the inside of the furnace is always in a closed state.

[0035] Reference Figures 7-10The second fixed plate 9 is connected to the right sealing plate 5 by a connecting rod 27. The inner wall of the feeding cylinder 2 is provided with a transmission groove, and a rotating gear 25 is rotatably connected in the transmission groove. A moving rod 26 is fixedly connected to each of the two sealing plates 5. A moving rack is provided on the opposite side of each of the two moving rods 26. The two moving racks are meshed with the rotating gear 25. Two symmetrically arranged sealing plates 5 are provided below the telescopic feeding cylinder 2. A flip plate 6 is provided above each of the two sealing plates 5. The flip plate 6 is connected to the feeding cylinder 2 by a hinge 7. When the two sealing plates 5 are not moved to the sides of the feeding cylinder 2, the sealing plates 5 will support the flip plate 6. This ensures that when the feeding cylinder 2 is not moved to the bottom of the feed inlet 3, the bottom of the feeding cylinder 2 will always be in a closed state, thereby preventing the heat inside the furnace body 1 from dissipating to the outside.

[0036] Reference Figure 4-5 The feeding cylinder 2 is provided with a first actuating rod 14 and a second actuating rod 15. Both the first actuating rod 14 and the second actuating rod 15 are connected to the rotating shaft 8. The rotating shaft 8 is rotatably connected to the side wall of the feeding cylinder 2. The outer side wall of the rotating shaft 8 is connected to a moving block 10. The rotating shaft 11 is fixedly connected to the rotating shaft 8. The actuating shaft is fixedly connected to the actuating disk 11. The inner side wall of the feeding cylinder 2 is slidably connected to the actuating frame 12. The actuating shaft is located inside the actuating frame 12. The bottom of the actuating frame 12 is provided with a mounting rod 13. The bottom of the mounting rod 13 is connected to the first actuating rod 14. The second actuating rod 15 is set in an inclined manner inside the feeding cylinder 2 and is slidably connected to the inner side wall of the feeding cylinder 2. The first actuating rod 14 is fixedly connected to a moving shaft. The second actuating rod 15 has a moving opening. The inner side wall of the moving opening is slidably connected to the moving shaft.

[0037] As the feeding cylinder 2 moves downward, the rotating shaft 8 rotates, which allows the first actuating rod 14 to move back and forth, and the second actuating rod 15 to move left and right. This allows the added material to be spread evenly inside the feeding cylinder 2, making it easier to feed the material evenly.

[0038] In this invention, when materials need to be added to the furnace, the materials are poured into the feeding cylinder 2. When the feeding cylinder 2 is at the top of the inlet 3, the second fixing plate 9 is inside the first fixing plate 4, and the two sealing plates 5 are in contact with each other and seal the bottom of the feeding cylinder 2. Then, the feeding cylinder 2 is moved down by controlling the electric push rod 17. During the downward movement of the feeding cylinder 2, the transmission gear 28 meshes with the transmission rack 18, thereby causing the rotating shaft 8 to rotate during the downward movement of the feeding cylinder 2. Then, under the action of the thread, the moving block 10 can move to the right end of the feeding cylinder 2, and at the same time drive the second fixing plate 9 to move. When the feeding cylinder 2 moves to the bottom of the inlet 3, the second fixing plate 9 will completely seal the top of the feeding cylinder 2.

[0039] During the movement of the second fixed plate 9, the right sealing plate 5 moves to the right, while the left sealing plate 5 moves to the left under the action of the moving rod 26 and the rotating gear 25. This opens the bottom of the feeding cylinder 2. It is worth mentioning that when the two sealing plates 5 have not moved to the sides of the feeding cylinder 2, the sealing plates 5 support the tilting plate 6. This ensures that the bottom of the feeding cylinder 2 remains closed when it does not move to the bottom of the feed inlet 3, thus preventing the heat inside the furnace 1 from dissipating to the outside. When the feeding cylinder 2 moves to the bottom of the feed inlet 3, the sealing plate 5 separates from the tilting plate 6, allowing the material to be poured into the furnace 1 under the action of gravity.

[0040] During the downward movement of the feeding cylinder 2, the energy storage spring 19 is compressed. When the feeding cylinder 2 moves to the bottom of the inlet 3, the top of the energy storage spring 19 also moves to the bottom of the sliding groove 20, releasing the elastic potential energy accumulated in the energy storage spring 19. Since the stiffness coefficient of the energy storage spring 19 is greater than that of the return spring 22, the return spring 22 is compressed. During this process, the two material dispersing rollers 21 rotate, and the material is poured down, which disperses the material to the bottom of the furnace body 1. Then, during the upward movement of the feeding cylinder 2, the upper end of the energy storage spring 19 moves up along the trajectory of the sliding groove 20, and the return block 24 is reset under the action of the return spring 22, facilitating the next feeding. This solves the problem of heat dissipation in the furnace body 1 during the feeding process and prevents the accumulation of added material, increasing the feasibility of the device.

[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
