[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Please see Figures 1 to 4This utility model provides a technical solution: a calcining furnace discharge device, including a calcining furnace body 1. Two support legs 2 are installed on each corresponding side of the bottom of the calcining furnace body 1. A support plate 3 is installed between the support legs 2. A convex groove 4 is formed inside the support plate 3. A convex slider 5 is slidably connected inside the convex groove 4. A support rod 6 is fixedly connected to the top of the convex slider 5. A sealing plate 7 is fixedly connected to one end of the support rod 6. A placement frame 8 is installed on one side of the sealing plate 7. A storage slot 24 is formed inside the placement frame 8. Multiple first limiting slots 25 and multiple second limiting slots 26 are formed on the sides corresponding to the storage slot 24 inside the placement frame 8. A partition plate 27 is inserted between the first limiting slots 25 and the second limiting slots 26. To separate the materials and prevent them from sticking together during calcination, thus affecting the calcination effect, the partition 27 can be inserted into different first limiting grooves 25 and second limiting grooves 26 as needed to adjust the distance between the partitions 27. A lead screw 9 is rotatably connected to the inside of the convex sliding groove 4 via a bearing. The lead screw 9 passes through the convex slider 5 and is threadedly connected to it, causing the convex slider 5 to rotate with the lead screw 9, thus moving the support rod 6 and the sealing plate 7. The placement frame 8 then moves in and out of the calcination furnace body 1, which helps prevent burns to workers. A movable bracket 23 is fixedly connected to the bottom of one end of the support rod 6, which helps to support the support rod 6 and the sealing plate 7, making the device more stable. A self-locking motor 10 is installed on one side of the support plate 3. A self-locking motor 10 with a locking function has its output end connected to a lead screw 9. A first protective cover 13 is fitted onto the outer side of the calcining furnace body 1, and a second protective cover 16 is fitted onto the outer side of the first protective cover 13. A first movable groove 11 and a second movable groove 14 are respectively opened on the top of the calcining furnace body 1 and the first protective cover 13. A first movable block 12 and a second movable block 15 are slidably connected inside the first movable groove 11 and the second movable groove 14, respectively. The first movable block 12 and the second movable block 15 are respectively connected to the first protective cover 13 and the second protective cover 16. Through the sliding of the second protective cover 16 and the first protective cover 13, and through a telescopic structure, the second protective cover 16 and the first protective cover 13 can be unfolded and retracted. The outer side of the support rod 6 is fitted with... A positioning sleeve 17 is attached, which is connected to the second protective cover 16. A locking bolt 18 is threaded onto one side of the positioning sleeve 17, with one end of the locking bolt 18 extending into the positioning sleeve 17. As the locking bolt 18 rotates, its other end presses against the support rod 6, fixing the positioning sleeve 17 and the support rod 6 in place. The positioning sleeve 17 can slide along with the support rod 6, causing the second protective cover 16 and the first protective cover 13 to slide, controlling the expansion and contraction of the second protective cover 16 and the first protective cover 13. This allows the placement frame 8 to be covered, protecting the calcined material. The support rod 6 can also be released, allowing the positioning sleeve 17 and the second protective cover 16 to slide independently, and the second protective cover 16 and the first protective cover 13 to be retracted, facilitating the loading and unloading of materials within the placement frame 8.The combined length of the first protective cover 13 and the second protective cover 16 is greater than the length of the placement frame 8, which helps to prevent the second protective cover 16 and the first protective cover 13 from obstructing the movement of the placement frame 8. A groove 19 is formed on the inner side of the second protective cover 16, and a nozzle 20 is installed inside the groove 19. A fan 21 is installed on the top of the second protective cover 16, and the output end of the fan 21 is connected to an air duct 22. One end of the air duct 22 is connected to the nozzle 20. Under the action of the fan 21, air is guided through the air duct 22 to the nozzle 20 and blown onto the material in the placement frame 8, which helps to accelerate the cooling of the material. A controller 28 is installed on the outer wall of the calcining furnace body 1, located on one side of the first protective cover 13.
[0022] In summary, when using this calcining furnace discharge device, the material is fed into the placement frame 8 on one side of the sealing disc 7. The positioning sleeve 17 on the outer side of the second protective cover 16 is slid. Through the connection between the positioning sleeve 17 and the second protective cover 16, and the sliding structure of the first protective cover 13 with the calcining furnace body 1 and the second protective cover 16 respectively, the second protective cover 16 and the first protective cover 13 unfold, covering the placement frame 8. Then, the locking bolt 18 threaded on one side of the positioning sleeve 17 is rotated, causing one end to press against the support rod 6, thus fixing the support rod 6 and the positioning sleeve 17. At this time, the self-locking motor 10 drives the lead screw 9 to rotate, causing the convex slider 5 and the support rod 6 to move. The sealing disc 7 at one end of the support rod 6 moves accordingly and seals the inlet and outlet of the calcining furnace body 1, sending the placement frame 8 and the material into the calcining furnace body 1. The second protective cover 16 slides down, pushing the first protective cover 13 back to its original position. The second protective cover 16 and the first protective cover 13 retract. After calcination, similarly, the lead screw 9 drives the convex slider 5 and the support rod 6 to move again, so that the sealing plate 7 can pull the placement frame 8 out of the calcination furnace body 1. At the same time, the second protective cover 16 and the first protective cover 13 unfold again, covering the placement frame 8. As needed, the fan 21 can be started to guide air through the air duct 22 to the nozzle 20 inside the second protective cover 16 and blow it onto the material in the placement frame 8 to cool it down. At this time, the locking bolt 18 is rotated to loosen the positioning sleeve 17 and the support rod 6. The positioning sleeve 17 and the second protective cover 16 slide in the opposite direction to retract the second protective cover 16 and the first protective cover 13, so that the placement frame 8 and the material can be exposed for discharge.
[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
