Description

Technical Field

[0001] This utility model relates to the technical field of refractory brick production, specifically a baking oven for standard brick production. Background Technology

[0002] Refractory materials are generally divided into two types: unshaped refractories and shaped refractories. Unshaped refractories, also known as castables, are mixed powdery granules composed of various aggregates and one or more binders. They must be mixed with one or more liquids and stirred evenly before use, and have strong fluidity. Shaped refractories generally refer to refractory bricks, which have standard and regular shapes, but can also be temporarily processed during construction as needed. In the production and processing of refractory bricks, baking equipment is often used to bake off the residual moisture inside to meet production requirements.

[0003] Utility model patent CN215559924U discloses a baking device for refractory brick production, belonging to the technical field of refractory brick production. It addresses the problems of existing technologies lacking a convenient feeding mechanism for rapid refractory brick feeding, leading to increased and cumbersome operation steps during feeding and discharging; and lacking a sealing mechanism for easy door sealing, resulting in temperature loss and affecting the firing effect of the refractory bricks. The device includes a baking oven with a rectangular groove inside. A first lead screw is rotatably connected inside the rectangular groove. A movable plate is threadedly connected to the surface of the first lead screw via a lead screw nut. A support frame is fixedly installed at the top of the movable plate, and a guide wheel is fixedly installed on one side of the bottom of the support frame. A fixed box is fixedly installed on the bottom of one side of the baking oven via a mounting plate.

[0026] 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.

[0027] Please see Figures 1 to 7 The present invention will describe the above technical solution in detail through the following embodiments:

[0028] A standard brick production baking oven includes: a heating box 1; a box cover 2 is hinged to the top of the heating box 1, a gearbox 3 is fixedly connected to the bottom of the heating box 1, a lifting plate 4 is provided inside the heating box 1, four bottom frames 5 are fixedly connected to the top of the lifting plate 4, a top frame 6 is hinged to the top of each bottom frame 5, and three brick bodies 7 are provided between each bottom frame 5 and the top frame 6; anti-crack mechanisms 8 are provided on both sides of the bottom frame 5 to improve the uniform heating of the brick bodies 7; a buckling mechanism 9 is provided on one side of the bottom frame 5 to fix the brick bodies 7; a lifting mechanism 10 is provided inside the gearbox 3 for easy material handling. The user places the brick bodies 7 inside the bottom frame 5, then closes the top frame 6 through the buckling mechanism 9, and then controls the brick bodies 7 to enter the heating box 1 through the lifting mechanism 10. While the heating box 1 bakes the brick bodies 7, the anti-crack mechanism 8 continuously controls the brick bodies 7 to rotate.

[0029] like Figure 3 and Figure 4 As shown, the crack prevention mechanism 8 includes: connecting blocks 11 fixedly connected to both sides of the bottom frame 5, wherein a first rotating shaft 12 is fixedly connected to the side of one connecting block 11 away from the bottom frame 5, and a second rotating shaft 13 is fixedly connected to the side of the other connecting block 11 away from the bottom frame 5. The end of the first rotating shaft 12 away from the connecting block 11 is rotatably connected to the support frame 14, and the end of the second rotating shaft 13 away from the connecting block 11 passes through the support frame 14, the heating box 1, and the side plate 15 and extends to the outside of the side plate 15. The support frame 14 is fixedly connected to the lifting plate 4. A protective box 16 is fixedly connected to the side plate 15 away from the heating box 1. The heating box 1 has a matching slot near the second rotating shaft 13. The lifting plate... A connecting plate 17 is fixedly connected near the side plate 15. One side of the connecting plate 17 passes through the heating box 1 and extends to the side plate 15. The side plate 15 is fixedly connected to the connecting plate 17. A matching stroke groove 18 is provided near the side plate 15 in the heating box 1. The protective box 16 is equipped with a power mechanism 19 that controls the synchronous rotation of four second rotating shafts 13. The power mechanism 19 controls the synchronous rotation of the four second rotating shafts 13. While the second rotating shafts 13 rotate, they drive the connecting block 11. The connecting block 11 drives the bottom frame 5. The bottom frame 5 rotates by cooperating with the first rotating shaft 12 and the support frame 14. While the bottom frame 5 rotates, it drives the brick body 7 to continuously flip through the cooperation of the top frame 6.

[0030] like Figure 3As shown, the power mechanism 19 includes: two first synchronous belts 20 are disposed inside the protective housing 16, and first synchronous pulleys 21 are connected to both sides of the first synchronous belts 20. The first synchronous pulleys 21 are respectively fixed to the outer surface of the second rotating shaft 13. A second synchronous pulley 22 is disposed on one side of each of the two first synchronous pulleys 21. The two second synchronous pulleys 22 are respectively fixed to the outer surface of the second rotating shaft 13, and the two second synchronous pulleys 22 are connected to each other by a second synchronous belt 23. One end of one of the second rotating shafts 13 passes through the protective housing 16 and extends to the motor 24. 4 is fixedly connected to the protective box 16, and the second rotating shaft 13 is fixedly connected to the output end of the motor 24. When the motor 24 is started, the output end of the motor 24 drives one of the second rotating shafts 13 to rotate. While the second rotating shaft 13 is rotating, the two lower second rotating shafts 13 are rotated synchronously through the cooperation of the second synchronous pulley 22 and the second synchronous belt 23. While the two lower second rotating shafts 13 are rotating, the two upper second rotating shafts 13 are driven through the cooperation of the first synchronous pulley 21 and the first synchronous belt 20, thereby controlling the four second rotating shafts 13 to rotate synchronously.

[0031] like Figure 6 and Figure 7 As shown, the latching mechanism 9 includes: two latches 25 on one side of the bottom frame 5, a matching cavity 26 at the latches 25 on the bottom frame 5, and a matching slot 27 at the top frame 6 near the latches 25; a spring 28 is installed inside the latches 25, one end of the spring 28 passes through the latches 25 and extends to the bottom frame 5. After the user places the brick body 7 inside the bottom frame 5, he rotates the top frame 6 to close the top frame 6 and the bottom frame 5. The latches 25, pushed by the spring 28, enter the slot 27 and thus fix the top frame 6. When the user needs to remove the brick body 7, he can push the latches 25 into the bottom frame 5 to separate the latches 25 from the slot 27 on the top frame 6, thereby opening the top frame 6.

[0032] like Figure 5As shown, the lifting mechanism 10 includes: a dual-axis motor 29 fixedly connected inside the gearbox 3; first bevel gears 30 fixedly connected to both output ends of the dual-axis motor 29; and second bevel gears 31 meshing on the side of the first bevel gears 30 away from the dual-axis motor 29; a screw 32 fixedly connected to the center of each of the second bevel gears 31; the top of each screw 32 penetrating the heating box 1 and the lifting plate 4 and extending to the fixing block 33; the screw 32 being rotatably connected to the heating box 1 and the fixing block 33; and the fixing block 33 being rotatably connected to the heating box 1. The lifting plate 4 is fixedly connected to the screw 32 by a thread. When the dual-axis motor 29 is started, the output end of the dual-axis motor 29 drives the first bevel gear 30, the first bevel gear 30 drives the second bevel gear 31, and the second bevel gear 31 drives the screw 32. The screw 32 rotates through the cooperation of the heating box 1 and the fixed block 33. While the screw 32 rotates, the lifting plate 4 is controlled. The user can control the brick body 7 to enter the heating box 1 and to remove the brick body 7 by controlling the forward and reverse rotation of the dual-axis motor 29.

[0033] like Figure 5 As shown, heating tubes 34 are fixedly connected to both sides of the inner wall of the heating box 1, and a temperature sensor 35 is fixedly connected to the top center of the lifting plate 4. A control box 36 with a timer is provided on one side of the heating box 1. The heating tubes 34 and the temperature sensor 35 are electrically connected to the control box 36. The user can set the heating time of the heating tubes 34 through the control box 36, and the temperature sensor 35 can also monitor the temperature inside the heating box 1 in real time.

[0034] like Figure 1 As shown, the bottom four corners of the gearbox 3 are equipped with universal wheels 37 with braking function. The universal wheels 37 are fixedly connected to the gearbox 3, which makes it convenient for users to move and fix the device.

[0035] Working principle: The user places the brick body 7 inside the bottom frame 5, then rotates the top frame 6 to close it with the bottom frame 5. The latch 25, pushed by the spring 28, enters the slot 27, thus fixing the top frame 6. Then, the motor 24 is started. The output of the motor 24 drives one of the second shafts 13 to rotate. Simultaneously, the rotation of the second shaft 13, through the cooperation of the second synchronous pulley 22 and the second synchronous belt 23, causes the two lower second shafts 13 to rotate synchronously. Simultaneously, the rotation of the two lower second shafts 13, through the cooperation of the first synchronous pulley 21 and the first synchronous belt 20, drives the two upper second shafts 13, thereby controlling the synchronous rotation of all four second shafts 13. Simultaneously, it drives the connecting block 11, which in turn drives the bottom frame 5. The bottom frame 5 rotates through the cooperation of the first rotating shaft 12 and the support frame 14. While the bottom frame 5 rotates, it drives the brick body 7 to continuously flip through the cooperation of the top frame 6. This allows the refractory bricks to be continuously flipped during the baking process, ensuring that the refractory bricks are heated evenly and preventing cracking due to uneven heating. This solves the problem that while existing standard brick production baking ovens can prevent heat loss inside the oven, they do not have the function of flipping the refractory bricks, causing the side of the refractory brick closest to the heat source to heat up faster, resulting in uneven heating and cracking during the baking process.

[0036] After the brick body 7 is baked, the user can open the box cover 2 and start the dual-axis motor 29. The output end of the dual-axis motor 29 drives the first bevel gear 30, which drives the second bevel gear 31. The second bevel gear 31 drives the screw 32. The screw 32 rotates through the cooperation of the heating box 1 and the fixing block 33. While the screw 32 is rotating, it controls the lifting plate 4. As the lifting plate 4 rises, it also lifts the baked brick body 7, so that the brick body 7 moves to the outside of the heating box 1. This allows the baked refractory brick to be lifted, making it convenient for the user to take out the baked refractory brick from inside the device. This simplifies the brick removal process and improves work efficiency.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
