Description

Technical Field

[0001] This utility model relates to the field of high-temperature kiln technology, and in particular to a discharge furnace door mechanism applied to high-temperature kilns. Background Technology

[0002] High-temperature kilns are industrial equipment that use microwave heating as their core technology. They convert electromagnetic energy into thermal energy through electronic and atomic polarization of matter in a microwave field. Based on differences in material properties, they can be divided into three categories: microwave transparent, total reflection, and absorptive. Absorbing materials (such as ceramics and metal powders) are the main application targets of this technology.

[0003] According to Chinese Patent No. CN209085320U, a discharge furnace door mechanism for high-temperature kilns is provided, comprising a high-temperature kiln body and a furnace door. A door sleeve is installed on the high-temperature kiln body, and the furnace door is slidably mounted on the sliding groove of the door sleeve. A base is fixed on the high-temperature kiln body, and a servo motor and a worm gear jack are installed on the base. The worm gear jack has a worm passage hole, and a worm wheel is provided inside the worm gear jack corresponding to the worm passage hole. A worm wheel shaft is installed through the center of the worm wheel, and a worm is slidably mounted in the worm passage hole of the worm gear jack. The servo motor has a power output shaft, which is connected to the input end through a first coupling. The bottom of the worm is fixedly connected to the top of the furnace door, and the furnace door has a discharge window with a discharge port. This utility model uses a servo motor to drive the worm to descend, which in turn drives the furnace door to descend, causing the discharge port on the furnace door to descend so that the material can be smoothly discharged into a flexible discharge cylinder.

[0004] The aforementioned patent effectively lowers the discharge port on the furnace door to facilitate the smooth discharge of materials into the flexible discharge cylinder. However, since the materials inside the high-temperature kiln are solid, manual feeding or discharging is still required when removing the materials. Although some high-temperature kilns currently use manual feeding or discharging, even with protective gear to prevent burns, people still have to lean into the kiln, which increases the risk and delays work efficiency. Therefore, a mechanism is needed to quickly discharge materials and prevent burns. Utility Model Content

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a discharge furnace door mechanism applied to a high-temperature kiln, comprising a furnace wall, a furnace door sliding groove fixedly connected to the outer surface of the furnace wall, a furnace door movably connected to the inner wall of the furnace door sliding groove, a driving block fixedly connected to the bottom of the furnace door, a sliding column fixedly connected to the inner surface of the furnace wall, a fixed ring fixedly connected to one side of the driving block, a movable rod movably connected to the outer surface of the fixed ring, a first bolt fixedly installed at the center of the fixed ring, a fixed block movably connected to one end of the movable rod, a second bolt fixedly installed on the inner surface of the fixed block, and a sliding ring fixedly connected to one end of the fixed block.

[0006] By adopting the above technical solution, the furnace door can be moved by the sliding grooves of the furnace door located at the upper and lower ends of the furnace wall. When the furnace door moves, the drive block at the bottom of the furnace door will move left and right along the first sliding column. At this time, the drive block will drive the movable rod to move due to the presence of the first bolt. When the movable rod moves, the sliding ring connected to it will move along the second sliding column. When the sliding ring moves, the second support block located on the upper surface of the sliding ring will also move. The load-bearing plate is connected to the second support block. When the second support block moves, the load-bearing plate will also move. The long strip groove and the first rotating column located at the bottom of the furnace wall will provide support for the forward protruding part of the load-bearing plate when the load-bearing plate moves.

[0007] A further feature of this invention is that the inner wall of the sliding ring is slidably connected with a second sliding post, and there are two sliding rings and two second sliding posts.

[0008] By adopting the above technical solution, when the drive block moves on the first sliding post, it will drive the movable rod to move. When the movable rod moves, it will drive the sliding ring to move on the second sliding post. When the sliding ring moves, the roller on its inner wall will be in close contact with the second sliding post, making it slide more quickly.

[0009] A further feature of this invention is that the inner wall of the furnace wall is provided with an elongated groove, and the surface of the elongated groove is provided with a movable groove.

[0010] By adopting the above technical solution, when the movable rod moves, not only the two ends of the movable rod will move, but the part in the middle that intersects with each other will also move together with the two ends of the movable rod. When moving, the first rotating column will move along the moving groove in the long strip.

[0011] A further feature of this invention is that there are two movable rods, and a third bolt is movably connected at the intersection of the two movable rods, with a support column fixedly connected to the bottom of the third bolt.

[0012] By adopting the above technical solution, the two movable rods are arranged in a cross shape, and a third bolt is used to fix them at the intersection. This provides both support and stability, and the first rotating column inside the support column at the bottom can also provide movement for the bolt at the intersection.

[0013] A further feature of this invention is that a first rotating column is rotatably connected to the bottom of the support column, and both ends of the first rotating column are sleeved together with the movable groove.

[0014] By adopting the above technical solution, the bolt passes through the two movable rods and is connected to the support column below. When the two ends of the movable rods move, the third bolt at the intersection will also move, the support column below the third bolt will also move, and the first rotating column will move in the moving groove.

[0015] A further feature of this invention is that a second rotating column is fixedly connected to the inner wall of the sliding ring, and a first roller is rotatably connected to the surface of the second rotating column.

[0016] By adopting the above technical solution, when the sliding ring moves on the second sliding post, the second rotating post and roller connected to the inner wall of the sliding ring will make the sliding ring move more quickly and will not have difficulty moving due to excessive friction between the sliding ring and the second rotating post.

[0017] A further feature of this invention is that an extension column is fixedly connected to the outer surface of the third bolt, and a support block is fixedly connected to one end of the extension column.

[0018] By adopting the above technical solution, when the overall mechanism is in operation, the load-bearing plate will protrude outwards, and the extension column and the rollers on the extension column will provide support. When the third bolt moves, it will also drive the extension column to move slowly.

[0019] A further feature of this invention is that a third rotating column is movably connected to the inner surface of the support block, and a second roller is rotatably connected to the surface of the third rotating column.

[0020] By adopting the above technical solution, because the moving speeds at both ends of the movable rod and the intersection are different, the rollers located below can provide support and stability when the load-bearing plate moves.

[0021] A further feature of this invention is that a second support block is fixedly connected to the outer surface of the sliding ring, and a load-bearing plate is fixedly connected to one side of the second support block.

[0022] By adopting the above technical solution, when the sliding ring moves along the second sliding column, the support block located on the upper surface of the sliding ring will also move, and the load-bearing plate connected to the sliding ring will move together with the support block.

[0023] A further feature of this invention is that the upper surface of the load-bearing plate is provided with elongated holes, and the number of elongated holes is multiple.

[0024] By adopting the above technical solution, the load-bearing plate itself is mountain-shaped, and the elongated holes it has are designed so that the heat below will not be blocked during high-temperature baking, thus making the heating more uniform and sufficient.

[0025] The beneficial effects of this utility model are: 1. This utility model, through the arrangement of the furnace wall, furnace door sliding groove, furnace door, drive block, first sliding column, fixed ring, movable rod, first bolt, fixed block, second bolt and sliding ring, when the movable furnace door moves in the furnace door sliding groove, the drive block located at the bottom of the furnace door will also move along the first sliding column. When the drive block moves to the left and right ends of the first sliding column, the movable rod connected to the drive block will also move to one end of the second sliding column. The location where the two movable rods intersect is more stable due to the presence of the third bolt, reducing the probability of failure. The sliding ring can move with the movable rod because of the presence of the fixed block and the second bolt. When the sliding ring moves, the third bolt moves at a different speed than it, so the support column below it and the first rotating column inside the support column need to move along the sliding groove.

[0026] 2. This utility model, through the arrangement of a second sliding column, a long groove, a moving groove, a third bolt, a support column, a first rotating column, a second rotating column, a first roller, an extension column, a support block, a third rotating column, a second roller, a second support block, a load-bearing plate, and a long hole, allows the sliding ring to move on the second sliding column when the furnace door is pushed. The sliding ring contains the second rotating column and the first roller, enabling it to slide quickly and stably on the second sliding column. When the sliding ring reaches a certain angle, the load-bearing plate protrudes from the entire kiln. The extension column, located on the outer surface of the third bolt, moves with the third bolt. Since the sliding ring and the third bolt move at different speeds, a roller is needed at one end of the extension column for sliding and to support the protruding load-bearing plate. The long hole on the load-bearing plate ensures more even baking. Attached Figure Description

The furnace door 3 can be moved by the furnace door sliding groove 2 located at the upper and lower ends of the furnace wall 1. When the furnace door 3 moves, the furnace door... The driving block 4 at the bottom of the 3rd section moves left and right along the first sliding column 5. Because of the presence of the first bolt 8, the driving block 4 drives the movable rod 7 to move. When the movable rod 7 moves, the sliding ring 11 connected to it moves along the second sliding column 12. When the sliding ring 11 moves, the second support block 24 located on the upper surface of the sliding ring 11 also moves. The load-bearing plate 25 is connected to the second support block 24. When the second support block 24 moves, the load-bearing plate 25 also moves. The elongated groove 13 at the bottom of the furnace wall 1 and the first rotating column 17 provide support for the forward-protruding part of the load-bearing plate 25 when it moves. The inner wall of the sliding ring 11 is slidably connected to the second sliding column 12. There are two columns 12. When the driving block 4 moves on the first sliding column 5, it drives the movable rod 7 to move. When the movable rod 7 moves, it drives the sliding ring 6 to move on the second sliding column 12. When the sliding ring 11 moves, the roller 19 on its inner wall will be in close contact with the second sliding column 12, making it slide faster. The inner wall of the furnace wall 1 is provided with a long strip groove 13. The surface of the long strip groove 13 is provided with a moving groove 14. When the movable rod 7 moves, not only the two ends of the movable rod 7 will move, but the part where they intersect in the middle will also move together with the two ends of the movable rod 7. When moving, the first rotating column 17 will move along the moving groove 14 in the long strip. There are two movable rods 7. The intersection of the two movable rods 7 is movably connected by a third bolt 15. The bottom of the three bolts 15 is fixedly connected to a support column 16. The two movable rods 7 are arranged in a cross shape, and the intersection is fixed by a third bolt 15, which provides support and stability. The first rotating column 17 inside the support column 16 at the bottom can also provide movement for the bolt 15 at the intersection. The bottom of the support column 16 is rotatably connected to the first rotating column 17. The two ends of the first rotating column 17 are sleeved with the moving groove 14. The bolt 15 passes through the two movable rods 7 and is connected to the support column 16 below. When the two ends of the movable rods 7 move, the third bolt 15 at the intersection will also move, and the support column 16 below the third bolt 15 will also move. The first rotating column 17 will move within the moving groove. The inner wall of the sliding ring 11 is fixedly connected to a second rotating column 18.The surface of the second rotating column 18 is rotatably connected to the first roller 19. When the sliding ring 11 moves on the second sliding column 12, the second rotating column 18 and the roller 19 connected to the inner wall of the sliding ring 11 will make the sliding ring 11 move more quickly, and will not be difficult to move due to excessive friction between the sliding ring 11 and the second rotating column 18. The outer surface of the third bolt 15 is fixedly connected to the extension column 20, and one end of the extension column 20 is fixedly connected to the support block 21. When the overall mechanism is running, it will be the part of the load-bearing plate 25 that protrudes outward, and the extension column 20 and the roller 22 on the extension column 20 will provide support. When the third bolt 15 moves, it will also drive the extension column 20 to move slowly. The inner surface of the support block 21 is movably connected to the third rotating column 22, and the surface of the third rotating column 22 is rotatably connected to the second roller 23. The moving speeds at the two ends of rod 7 and the two intersection points are different. Therefore, when the load-bearing plate 25 moves, the roller 22 located below can provide support and stability during movement. A second support block 24 is fixedly connected to the outer surface of the sliding ring 11, and a load-bearing plate 25 is fixedly connected to one side of the second support block 24. When the sliding ring 11 moves along the second sliding column 12, the support block 21 located on the upper surface of the sliding ring 11 also moves, and the load-bearing plate 25 connected to the sliding ring 11 moves along with the support block 21. The upper surface of the load-bearing plate 25 has multiple elongated holes 26. The load-bearing plate 25 itself is mountain-shaped, and the elongated holes 26 prevent the heat from being blocked during high-temperature baking, thus making the heating more uniform and thorough.

[0031] In this invention, when the movable furnace door 3 moves along the furnace door sliding groove 2, the drive block 4 located at the bottom of the furnace door 3 also moves along the first sliding column 5. When the drive block 4 moves to the left and right ends of the first sliding column 5, the movable rod 7 connected to the drive block 4 also moves to one end of the second sliding column 12. The location where the two movable rods 7 intersect is more stable due to the presence of the third bolt 15, reducing the probability of malfunction. The sliding ring 11 can move with the movable rod 7 because of the presence of the fixed block 9 and the second bolt 10. When the sliding ring 11 moves, the third bolt 15 moves at a different speed than it, so the support column 16 located below it and the first rotating column 17 inside the support column 16 need to move along the moving groove 14. When the furnace door 3 is opened, the movable rod 7 will also push the sliding ring 11 to move on the second sliding column 12. The sliding ring 11 has a second rotating column 18 and a first roller 19 inside, so the sliding ring 11 can slide quickly and stably on the second sliding column 12. When the sliding ring 11 reaches a certain angle, the load-bearing plate 25 will protrude from the entire kiln, and the extension column 20 located on the outer surface of the third bolt 15 will move with the third bolt 15. The sliding ring 11 and the third bolt 15 move at different speeds, so a roller 23 is needed at one end of the extension column 20 to slide and also to support the protruding load-bearing plate 25. The long strip hole 26 opened on the load-bearing plate 25 can make the baking more uniform.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
