[0018] Example

[0019] Please see Figure 1-6A prefabricated burner component for a lime kiln includes a base plate 13. A first generating plate 1 and a second generating plate 2 are fixedly connected to the base plate 13 and are connected via a transmission plate 3. One end of the first generating plate 1 is connected to an igniter. A slider 14 is slidably connected to the base plate 13, and a rotating shaft 7 is rotatably connected within the slider 14. A carrier plate 9 is fixedly connected to the rotating shaft 7. A mold 8 is connected to the carrier plate 9 via an extrusion mechanism. The extrusion mechanism includes an extrusion unit and a movable unit. The extrusion unit includes a cylinder 4, a metal wedge plate 5, a wedge block 6, and a protruding plate 15. The fixed end of the cylinder 4 is fixed... The cylinder 4 is fixedly connected to the frame. The movable end of the cylinder 4 is fixedly connected to the metal wedge plate 5 and the slider 14. The wedge block 6 is elastically slidably connected inside the generating plate 2. A circular convex plate 15 is fixedly connected to the wedge block 6. The convex plate 15 includes a large convex plate and a small convex plate. The volume of the large convex plate is larger than that of the small convex plate. The wedge block 6 is located on the moving path of the metal wedge plate 5. A guide block is fixedly connected to the metal wedge plate 5. A vertical plate 19 fixedly connected to the frame is provided on one side of the metal wedge plate 5. A guide groove 17 is opened in the vertical plate 19. The guide block rotates unidirectionally along the guide groove 17.

[0020] The active unit includes a moving shaft 10, a push plate 11, and a polygonal groove 12. The carrier plate 9 has a polygonal groove 12, which includes multiple slides. Each slide is elastically connected to a push plate 11. The moving shaft 10 slides in the corresponding slide. The moving shaft 10 and the mold 8 are fixedly connected.

[0021] A gear 16 is fixedly connected to the rotating shaft 7, and a rack 18 is fixedly connected to the base plate 13. The gear 16 and the rack 18 mesh and drive each other.

[0022] In use, cylinder 4 is activated, causing its movable end to simultaneously move the metal wedge plate 5 and the slider 14. On the metal wedge plate 5 side, the metal wedge plate 5 presses against the wedge block 6, pushing it out of the generating plate 2. The wedge block 6 then drives the convex plate 15 to press against the mold 8. The larger convex plate causes a larger displacement of the mold 8, while the smaller convex plate causes a smaller displacement. The slider 14, driven by the thrust of cylinder 4, moves the rotating shaft 7. The rotating shaft 7, through the meshing transmission between gear 16 and rack 18, rotates within the slider 14 while simultaneously rotating the carrier plate 9. The carrier plate 9, through the moving shaft 10, causes the mold 8 to rotate synchronously. The number and angle of the sliding tracks in the polygonal groove 12 correspond to the spacing of the convex plates 15. This allows the mold 8 to be pushed along a corresponding slide when the protruding plate 15 presses against it. According to force decomposition, the circular protruding plate 15 provides force along a slide to the mold 8, causing it to move. There is a gap between the large and small protrusions. When this gap moves to one side of the mold 8, the mold 8 resets under the elastic force of the push plate 11. This method of moving and vibrating the mold 8 facilitates rapid vibration of the raw material within the mold 8, filling the entire cavity and facilitating the molding of the preform. Afterwards, the metal wedge plate 5 continues to move, entering the groove of the wedge block 6. In detail, the displacement of the metal wedge plate 5 at the end of the mold 8 driven by the wedge block 6 and the convex plate 15 is called the extrusion section. The section where the metal wedge plate 5 moves into the groove inside the wedge block 6, and the convex plate 15 does not extrude the mold 8, is called the baking section. Whether in the extrusion section or the baking section, the mold 8 is always rotating. If it is necessary to extend the vibration time of the mold 8, the metal wedge plate 5 can be moved repeatedly in the extrusion section. After the vibration is completed, the cylinder 4 pushes the metal wedge plate 5 into the baking section. At this time, the wedge block 6 retracts into the second generating plate 2. The mold 8 continues to rotate under the meshing action of the gear 16 and the rack 18, and is baked by the flames sprayed from the first generating plate 1 and the second generating plate 2, driving the metal wedge plate 5. Moving back and forth in the baking section facilitates baking and shaping of the raw material inside mold 8 from multiple directions, improving the efficiency and quality of preform forming within mold 8. After baking, the moving end of cylinder 4 drives the metal wedge plate 5 to retract. Utilizing the toughness and deformability of metal, the metal wedge plate 5 can be manipulated by rationally designing the ratio and position of its multiple areas. This allows the metal wedge plate 5 to drive the guide block to move along the guide groove 17 in the sequence of segments c, a, b, and c. Steps are provided between each pair of segments c, a, and b to prevent the metal wedge plate 5 from moving in the opposite direction. This allows the metal wedge plate 5 to slide out from the inclined surface of the groove on the wedge block 6, and the preform can be removed. Compared to existing technologies, this design not only integrates vibration and baking but also allows for manual control of the vibration and baking time, greatly improving operational flexibility.

[0023] Example 2

[0024] Please see Figure 1 and Figure 2 Based on the above embodiments, the mold 8 is rotatably connected with a lifting lug.

[0025] The mold 8 is slidably connected to an end cap, which has an air vent.

[0026] The rotatable connection between the lifting lug and the mold 8 improves the stability of the crane when lifting the mold 8. The rotation of the mold 8 reduces the rotation of the crane cable, thus maintaining the stability of the mold 8. When the end cap slides, it can scrape off excess material along the edge of the mold 8, further reducing the effort required for manual scraping.
