Description

Technical Field

[0001] The invention belongs to the technical field of blue brick production, and in particular relates to a kiln for firing antique blue bricks. Background Art

[0002] Blue bricks are sintered bricks. The main raw material of antique blue bricks is clay. After the clay is mixed with water, it is extruded into shape, and then baked in a brick kiln (about 1000 degrees) and cooled with water to prevent the iron in the clay from being completely oxidized, making it more resistant to weathering and water. Blue bricks are significantly better than red bricks in terms of anti-oxidation, hydration, and atmospheric erosion. When used as masonry materials, they can extend the life of buildings.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Next, the embodiments are described in detail to enable those skilled in the art to better understand the present invention: A kiln for firing antique blue bricks, such as Figures 1 to 6 As shown, the kiln body 1 includes a base 2 at one end of the kiln body 1, and a transporting pallet 3 is slidably mounted on the base 2. The transporting pallet 3 can slide on the base 2 to facilitate the transportation of green bricks. A slot 17 corresponding to the moving pallet 3 is opened at the bottom of the inner side of the kiln body 1. After the transporting pallet 3 enters the slot 27, it is engaged with the slot 27 to form the bottom of the kiln body 1. The transporting pallet 3 is an L-shaped structure, and heat insulation materials such as calcium silicate board, aluminum silicate and rock wool are installed on the transporting pallet, respectively. Figure 1 and Figure 2 As shown, an entrance is provided on the kiln body 1. When the transporting pallet 3 is pushed into the kiln body 1, one end of the pallet blocks the entrance of the kiln body 1 to achieve sealing and heat insulation, so that the green bricks can be fired well inside the kiln body 1. A plurality of square green brick brackets 4 are arranged on the transporting pallet 3, which are used to place green bricks for firing. The plurality of green brick brackets 4 are rotatably mounted on the transporting pallet 3, so that when the transporting pallet 3 is pushed into the kiln body 1 to fire the green bricks, each green brick bracket 4 can be rotated, so that each green brick thereon can achieve uniform heating and firing, thereby improving the firing quality of the green bricks.

[0026] The details are as follows. First, Figure 1 and Figure 2As shown, a gear assembly is provided at the inner bottom of the transporting cart 3, and the gear assembly is rotatably connected to a plurality of blue brick brackets 4 respectively. A driving motor 5 is provided at one end of the base 2, and the driving motor 5 is rotatably connected to the gear assembly. When the driving motor 5 is started, the plurality of blue brick brackets 4 can be driven to achieve a rotation effect, so that each blue brick thereon can be fired evenly heated in the kiln body 1. A circulating water cooling device 28 for cooling the gear assembly is installed at the bottom of the kiln body 1. The circulating water cooling device 28 is connected to the cooling device for cooling the entire kiln furnace, and is used to cool the gear assembly to prevent the high temperature from affecting the operation of the gear assembly.

[0027] The bottom of each green brick support 4 is connected with a circular turntable 6, which is rotatably mounted on the transporting pallet 3. The rotation of the circular turntable 6 drives the rotation of the green brick support 4, and the bottom of each circular turntable 6 is connected with a support column 7, which is slidably mounted in the guide groove 26 and limited by the circular turntable 6, so that the circular turntable 6 slides on the transporting pallet 3. The first rotating gear 8 is respectively sleeved on the support column 7, the support seat 11 is mounted on the inner bottom of the transporting pallet 3, the fixed gear 13 is fixedly mounted on the support seat 11, and the first rotating gear 8 is meshed with the fixed gear 13. The pressure bearing 12 is mounted on the inner bottom of the transporting pallet 3, the gear ring 10 is fixedly mounted on the pressure bearing 12, and the first rotating gear 8 is meshed with the gear ring 10. The second rotating gear 9 is rotatably mounted in the transporting pallet 3, and partially extends to the outside of the transporting pallet 3. The second rotating gear 9 is respectively meshed with the gear ring 10 and the power transition gear 17. When the driving motor 5 is started, the power transition gear 17 drives the second rotating gear 9 to rotate, the second rotating gear 9 drives the ring gear 10 to rotate, and the ring gear 10 drives the first rotating gear 8 to rotate. Since the fixed gear 13 is fixed, the first rotating gear 8 rotates around the fixed gear 13 while rotating. While each green brick support 4 rotates, the green brick support 4 located in the center of the kiln body 1 can be moved to the edge of the kiln body 1. In the heating stage, the temperature at the center and the edge of the kiln body 1 is inconsistent. The present invention allows each green brick to be fired evenly in the kiln body 1.

[0028] Specifically, first, the driving motor 5 is invertedly installed on the base 2, and a driving gear 14 is installed on the output shaft of the driving motor 5 and is located at the bottom of the base 2. A coupling gear 15 is provided at the bottom of the base 2 and at one end away from the driving gear 14. The driving gear 14 and the coupling gear 15 are rotatably connected to each other through a steel belt 16. A power connection component is provided on the side wall of one end of the transport cart 3. When the driving motor 5 is started, the driving gear 14 rotates, and the power of the driving gear 14 is transmitted to the coupling gear 15 through the steel belt 16. After the power connection component and the coupling gear 15 are rotatably connected to each other, the power connection is realized, so that the entire blue brick bracket 4 can rotate.

[0029] Specifically, the power connection assembly includes a power transition gear 17, on which a connecting rod 18 is provided, and a support rod 19 is provided on the side wall of one end of the transport cart 3. The connecting rod 18 is rotatably and slidably installed on the support rod 19, that is, the connecting rod 18 can rotate on the support rod 19, and can also slide on the support rod 19. A coupling hole 20 is provided above the coupling gear 15. The connecting rod 18 slides deep into the coupling hole 20 and is connected to the coupling gear 15, thereby realizing power connection.

[0030] The connection method is that a short clamping rod 21 is provided at the bottom of one end of the connecting rod 18, and a short clamping groove 22 that cooperates with the short clamping rod 21 is provided on the coupling gear 15. When the short clamping rod 21 is inserted into the short clamping groove 22, the driving force of the driving motor 5 can be connected. Since the power transition gear 17 at this time will also be slidably engaged with the second rotating gear 9, when the power transition gear 17 rotates, the second rotating gear 9 also rotates. The second rotating gear 9 also realizes the rotation of the ring gear 10 by engaging with the ring gear 10. Since the ring gear 10 is engaged with the first rotating gear 8, the first rotating gear 8 drives the entire blue brick bracket 4 to rotate under the action of the ring gear 10.

[0031] When all the green bricks are fired, the transporting trolley 3 can be pushed out of the kiln body 1 by pulling out the clamping short rod 21. The separate connection realizes flexible power interruption and efficient green brick firing production.

[0032] Furthermore, the outer wall of each blue brick bracket 4 is a grid structure to improve the permeability of flame and evenly heat and burn the blue bricks, and the outer wall of each blue brick bracket 4 is made of metal material to improve high temperature resistance and increase service life.

[0033] At the same time, the interior of the blue brick bracket 4 is provided with multiple layers of blue brick interlayers 23, which are arranged in a longitudinal stacking structure. When placing blue bricks, they can be placed from the side of the blue brick bracket 4. An interlayer baffle 24 is provided under each blue brick interlayer 23. A certain gap is set between each interlayer baffle 24, so that when the blue bricks are fired, the bottom of the blue bricks can also be heated, avoiding the traditional stacking and stacking firing state, and each interlayer baffle 24 is a grid structure, so that the flame can evenly penetrate the interior of the blue brick bracket 4, and the blue bricks are evenly heated and fired, and each interlayer baffle 24 is also made of metal material to ensure the service life.

[0034] In summary, by providing a blue brick support 4 with a rotating structure, the blue brick support 4 can rotate 360 ​​degrees when the blue bricks are fired inside the kiln body 1, and the blue brick support 4 located in the center of the kiln body 1 can be moved to the edge of the kiln body 1, so that the blue bricks can achieve a multi-faceted uniform heating and firing effect, and by providing a plurality of interlayer baffles 24 with space gaps, the traditional stacking and stacking firing state is avoided, thereby improving the firing quality of the blue bricks.
