Abstract
Description
Technical Field
[0001] This utility model relates to the field of refractory brick production technology, specifically to a heat preservation device for refractory brick production. Background Technology
[0002] Refractory bricks, also known as fire bricks, are refractory materials made from refractory clay or other refractory raw materials. They are pale yellow or brownish in color and are mainly used for lining smelting furnaces, capable of withstanding high temperatures of 1,580℃–1,770℃. They are also called fire bricks, and refer to refractory materials with specific shapes and sizes. Based on the manufacturing process, they can be classified as fired bricks, unfired bricks, electrofused bricks (cast bricks), and refractory insulating bricks. Based on shape and size, they can be classified as standard bricks, ordinary bricks, and special-shaped bricks. They can be used as high-temperature building materials and structural materials for kilns and various thermal equipment, and can withstand various physicochemical changes and mechanical actions at high temperatures. Examples include refractory clay bricks, high-alumina bricks, silica bricks, and magnesia bricks.
[0003] A search revealed Chinese patent application CN202223418533.0, which discloses a heat preservation device for refractory brick production. The device includes a high-temperature furnace with an internal chamber. A limiting frame is constructed on one side of the upper surface of the high-temperature furnace. A partition component for dividing the chamber into a sintering chamber and a heat preservation chamber is movably installed within the limiting frame. Limiting pins are centrally inserted into both sides of the limiting frame. The partition component includes a partition plate with a sealing frame mounted on its four sides. Limiting holes extending into the partition plate are opened on the top of both sides of the sealing frame. One end of each limiting pin can be inserted into a limiting hole. A lifting handle is centrally located on the upper surface of the partition plate, with both ends welded and fixed to the upper surface of the partition plate. A furnace side cover is detachably installed on one end of the high-temperature furnace. This heat preservation device for refractory brick production has a reasonable structure, which is beneficial for improving the production efficiency of refractory bricks and is highly practical.
[0004] The existing device described above only has a furnace side cover on one side of the high-temperature furnace. The refractory bricks that have finished heat preservation can only be transported out through this door. If two batches of refractory bricks are produced consecutively, they can only be transported out together after the heat preservation of the second batch of refractory bricks is completed. Therefore, it is impossible to achieve the continuous sintering process mentioned in the above device. In addition, the above device drives the support frame to move through the ball screw, and the previous support frame will block the next support frame, which is inconvenient for workers to operate. Therefore, this utility model provides a heat preservation device for refractory brick production. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5 This utility model provides a technical solution: It includes a kiln 1, with kiln cover plates 2 hinged to both ends. An insulation plate 3 is inserted inside the kiln 1 to divide the kiln chamber into a sintering chamber and a heat preservation chamber. Two tracks 4 are laid on the inner bottom wall of the kiln 1, and two kiln cars 5 roll along the tracks 4. An insulation plate 6 is fixedly installed on the upper surface of each kiln car 5, and a load-bearing frame 7 is fixedly installed on the upper surface of the insulation plate 6. Multiple mounting plates 8 are inserted inside the load-bearing frame 7. A baffle 9 is fixedly installed at the bottom of each kiln car 5. Two parallel chutes 10 are formed inside the kiln 1. All are equipped with ball screws 11, and sliders 12 are threadedly engaged with the surface of the ball screws 11. One-way pushers 13 are fixedly mounted on the upper surface of the sliders 12. A worm gear 14 is fixedly mounted on one end of the ball screws 11. Two drive motors 15 are fixedly mounted at the bottom of the kiln 1. The output ends of the two drive motors 15 are connected to the worm gear 14 through a worm 16. Grooves are provided on both sides of the inner wall of the kiln 1 for sliding connection with the heat insulation plate 6. Locks 17 are fixedly mounted on both sides of the outer wall of the kiln 1. The two one-way pushers 13 are in the same direction. A lifting handle 18 is provided in the center of the upper surface of the heat insulation plate 3. The structure comprises a cover plate 2, heat insulation plate 1, track 4, kiln car 5, heat insulation plate 2, load-bearing frame 7, mounting plate 8, baffle 9, chute 10, ball screw 11, slider 12, one-way pusher 13, worm gear 14, drive motor 15, and worm 16. During operation, after the bricks in the sintering chamber have finished sintering, heat insulation plate 13 is lifted by the handle 18. This causes the drive motor 15 to rotate the ball screw 11, while the slider 12 moves along the chute 10. At this time, the one-way pusher 13 abuts against the baffle 9 at the bottom of the kiln car 5, pushing the kiln car 5 into the insulation chamber. During the movement of the kiln car 5, its bottom... The baffle 5 will pass over the one-way pusher 13 on another slider 12, then lower the heat insulation plate 3 and open one end of the kiln 1 to the furnace cover plate 2. Subsequently, the kiln car carrying bricks will be transported by the conveying device to the track inside the kiln 1. Then, the furnace cover plate 2 will be closed, and the drive motor 15 will reverse to drive the slider 12 back to its original position. Then, when the heat preservation of the bricks in the heat preservation chamber is finished, the furnace cover plate 2 at the other end of the kiln 1 will be opened. At this time, the drive motor 15 on the other side will drive another one-way pusher 13 to push the kiln car 5 out of the kiln 1, thereby realizing the continuous sintering and heat preservation processing of refractory bricks and effectively improving production efficiency.
[0025] In summary, this heat preservation device for refractory brick production is configured with the following components: furnace cover plate 2, heat insulation plate 1 3, track 4, kiln car 5, heat insulation plate 2 6, load-bearing frame 7, mounting plate 8, baffle 9, slide groove 10, ball screw 11, slider 12, one-way pusher 13, worm gear 14, drive motor 15, and worm 16. During use, after the bricks in the sintering chamber have finished sintering, heat insulation plate 1 3 is lifted by pulling handle 18. Simultaneously, the drive motor 15 drives the ball screw 11 to rotate, and the slider 12 moves along the slide groove 10. At this time, the one-way pusher 13 abuts against the baffle 9 at the bottom of the kiln car 5, pushing the kiln car 5 into the heat preservation chamber. During the movement, the bottom baffle 5 will pass over the one-way pusher 13 on another slider 12, and then the heat insulation plate 3 will be lowered and the furnace cover plate 2 at one end of the kiln 1 will be opened. Then the kiln car carrying bricks will be transported to the track inside the kiln 1 by the conveying device. After the furnace cover plate 2 is closed, the drive motor 15 reverses to drive the slider 12 back to the original position. Then, when the heat preservation of the bricks in the heat preservation chamber is finished, the furnace cover plate 2 at the other end of the kiln 1 will be opened. At this time, the drive motor 15 on the other side will drive another one-way pusher 13 to push the kiln car 5 out of the kiln 1, thereby realizing the continuous sintering and heat preservation processing of refractory bricks and effectively improving production efficiency.
