Description

Technical Field

[0001] The invention relates to the technical field of fly ash autoclaved bricks, in particular to a heating device for producing fly ash autoclaved bricks. Background Art

[0002] Autoclaved fly ash bricks are made from fly ash, lime, or cement as the primary raw materials, with appropriate amounts of gypsum and aggregates, through a mixture preparation, press-forming, and high-pressure, normal-pressure, or natural curing. Fly ash bricks are made from fly ash and lime as the primary raw materials, with appropriate amounts of gypsum and aggregates, through a process of blank preparation, press-forming, and high-pressure steam curing. There are two types of fly ash bricks: non-autoclaved fly ash bricks and autoclaved fly ash bricks. Autoclaved fly ash bricks are fly ash bricks cured with high-pressure steam. Autoclaved fly ash bricks are fly ash bricks cured with steam at normal pressure. The raw materials and production processes for these two types of bricks are essentially the same, but their curing processes and properties differ. Autoclaved fly ash bricks are cured in saturated steam pressure (steam temperature above 174.5°C and working pressure above 0.8 MPa), allowing the active components in the brick to fully undergo hydrothermal reactions, resulting in high strength and stable properties. Steam-cured fly ash bricks may be prone to cracking in the wall. The compressive strength of autoclaved fly ash bricks is generally higher, reaching 20MPa or 15MPa, at least 10MPa, and can withstand 15 freeze-thaw cycles. In addition, fly ash bricks are a potentially active hydraulic material that can continue to produce hydration reactions in a humid environment, making the internal structure of the bricks more dense, which is conducive to improving strength.

[0003] First, during the heating process, heat is not evenly distributed across each brick due to the varying shapes and sizes of fly ash autoclaved bricks and the uneven airflow distribution within the heating device. This uneven heat distribution is particularly prominent in actual production, resulting in poor heating of some bricks and, in turn, impacting product quality. For example, the fixed hot air inlet in conventional devices creates dead zones in the hot air distribution, leading to uneven heating of the bricks. For example, sufficient heating at the top but insufficient heating at the bottom or sides can easily cause internal stress cracks, seriously impacting the brick's strength and service life. Second, while some conventional devices have attempted to improve hot air distribution by increasing the number of hot air nozzles or adjusting their positions, these methods still fail to fundamentally address the issue of dead zones. Furthermore, the adjustment methods are complex, making it difficult to precisely adjust to the actual shape and size of the bricks. Furthermore, the hot air nozzles in conventional heating devices are fixed in position and angle, making them incapable of dynamic adjustment based on the shape and size of the bricks, resulting in low heating efficiency and significant energy waste. Finally, conventional heating devices have a low level of automation and lack real-time monitoring and feedback control capabilities. During the heating process, it is impossible to monitor the temperature changes on the brick surface in real time, nor is it possible to automatically adjust the direction and intensity of the hot air jet according to the temperature difference, resulting in poor controllability of the heating process and large fluctuations in product quality.

[0004] Therefore, based on the above search and in combination with the prior art, a heating device for producing fly ash autoclaved bricks is proposed to solve the above problems. Summary of the Invention

[0005] The object of the present invention is to provide a heating device for producing fly ash autoclaved bricks to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0008] Furthermore, the adjustment component includes: multiple circular iron blocks, which are respectively fixedly installed on the left and right side walls of multiple lower connecting plates, and the outer surface of the ring is provided with a groove, and the inner wall of the groove is fixedly installed with multiple circular electromagnets, which can cooperate with the circular iron blocks.

[0009] Furthermore, the circulation parts include: connecting chambers, which are fixedly installed on the bottom surface of the lower connecting plate, the bottom surface of the connecting chamber is provided with heating pipe 1, the side wall of the connecting chamber is provided with heating pipe 2, and the other end of the heating pipe 2 is connected to the interior of the sphere.

[0010] Furthermore, a mounting groove is provided on the top surface of the lower connecting plate, an electric push rod is fixedly installed inside the mounting groove, and an output end of the electric push rod is fixedly connected to the bottom surface of the upper connecting plate.

[0011] Furthermore, fixed iron blocks are fixedly installed on the front and rear sides of the inner walls of the plurality of collars, and sliding grooves are provided on the side walls of the fixed iron blocks.

[0012] Furthermore, electromagnetic rods are fixedly installed on the support columns of the front and rear side walls of the tank mouth, and the electromagnetic rods pass through the slide grooves on the fixed iron block, and the fixed iron block can slide on the electromagnetic rods.

[0013] Furthermore, a controller is fixedly mounted on the front side wall of the support base, and a distribution box is fixedly mounted on the front side wall of another support base.

[0014] Furthermore, a processor is fixedly mounted on the rear side wall of one of the support bases.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By incorporating multiple hot steam ejection and adjustment components, the uneven heat distribution problem in traditional fly ash autoclaved brick heating devices can be effectively addressed. The hot steam ejection assembly, consisting of key components such as an adjustable air outlet nozzle, a sphere, a spherical groove, and a temperature sensor, automatically adjusts the direction and intensity of the hot air jet according to the shape and size of the brick. The air outlet nozzle, through the coordination of the sphere and the spherical groove, achieves multi-angle deflection with an adjustment range of up to ±30°, ensuring that the hot air precisely reaches every part of the brick and avoiding blind spots caused by irregular shapes or sizes. Furthermore, the circular electromagnet and circular iron block in the adjustment assembly work together to flexibly adjust the horizontal position, further optimizing the hot air distribution range. Furthermore, a temperature sensor monitors the brick surface temperature in real time and feeds this data back to the processor. Based on this monitoring result, the system automatically triggers an adjustment mechanism to dynamically adjust the angle and position of the air outlet nozzle to ensure uniform temperature across all areas of the brick. This intelligent and dynamic adjustment method not only improves heating efficiency, but also significantly enhances product quality. It effectively avoids internal stress cracks caused by local overheating or underheating, extends the service life of the brick, and provides a more efficient and reliable heating solution for the production of fly ash autoclaved bricks.

[0017] 2. By providing mechanical structures such as an electric push rod, an electromagnetic rod, and a fixed iron block, the present invention shows significant advantages in adjusting the hot air injection distance and coverage range. The telescopic function of the electric push rod enables the air outlet nozzle to flexibly adjust the distance from the brick body according to the actual needs of the brick body. For example, when it is necessary to enhance the local heating effect, the electric push rod can push the air outlet nozzle out, shortening the distance between it and the brick body to 50-100mm, thereby concentrating the hot air to cover the low-temperature area and improving the heating efficiency. At the same time, the coordinated use of the electromagnetic rod and the fixed iron block can realize the up and down movement of the ring as a whole, further optimize the vertical position of the air outlet nozzle, and ensure that the hot air can evenly cover the bottom bricks of the brick placement bin. The synergistic effect of this mechanical structure not only improves the utilization efficiency of the hot air, but also avoids the problem of insufficient bottom or side heating that is common in traditional fixed nozzle designs.

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 making creative efforts are within the scope of protection of the present invention.

[0029] In a typical implementation of this application, please refer to Figures 1 to 9 As shown, a heating device for producing fly ash autoclaved bricks comprises: a support base 1, two support bases 1 are provided, a brick heating steamer body 2 is fixedly installed on the top surface of the two support bases 1, the support base 1 is used to support the brick heating steamer body 2, the left side wall of the brick heating steamer body 2 is rotatably connected to a tank door 7 through a vertical rotating shaft 6, a tank opening 8 is opened on the left side wall of the brick heating steamer body 2, the tank door 7 can cover or completely stagger the tank opening 8, cover when heating the bricks, and stagger after heating is completed, a brick placement bin 10 is fixedly installed inside the tank opening 8 through a plurality of support columns 9, the interior of the brick placement bin 10 is used to place bricks, the operator rotates the tank door 7 through the vertical rotating shaft 6, and neatly stacks the fly ash autoclaved bricks to be heated in the brick placement bin 10 ( Figure 4 ). Close the tank door 7 so that it completely covers the tank opening 8 to ensure that the interior of the steamer is sealed. At this time, the support column 9 fixes the brick placement bin 10 to prevent the bricks from shifting during the heating process;

[0030] The hot gas ejection assembly is provided with multiple groups, which are respectively provided on the tank mouth 8. The hot gas ejection assembly includes:

[0031] The collar 11 is arranged on the tank mouth 8. The inner wall of the collar 11 is provided with a circular groove 12. The inner wall of the circular groove 12 is provided with a lower connecting plate 13. The top surface of the lower connecting plate 13 is provided with an upper connecting plate 14. The upper connecting plate 14 is T-shaped. A spherical groove 18 is provided on the top surface of the upper connecting plate 14. A sphere 19 is movably installed inside the spherical groove 18. The inner wall of the spherical groove 18 is provided with multiple electromagnets. The multiple electromagnets can adjust the adsorption of the sphere 19. An air outlet nozzle 20 is fixedly installed on the top of the sphere 19. The interior of the sphere 19 is connected to the air outlet nozzle 20. A temperature sensor 21 is fixedly installed on the top surface of the upper connecting plate 14. The temperature sensor 21 monitors the surface temperature of the brick in real time and feeds back the data to the processor 5. If the temperature difference is detected to exceed the set threshold (such as ±5°C), the system automatically triggers the adjustment mechanism. The hot steam ejection component also includes a circulation part;

[0032] The controller 3 is started and the distribution box 4 supplies power to the system. After receiving the instruction, the processor 5 activates the steam pipe in the brick heating steamer body 2, and the hot steam enters the communication chamber 15 through the heating pipe 16.

[0033] The hot steam is transported to the interior of the sphere 19 through the heating pipe 17 and finally ejected from the air outlet nozzle 20. In the initial state, the angle of the air outlet nozzle 20 is fixed by the adsorption effect of the electromagnet in the spherical groove 18 to ensure that the hot air is sprayed vertically to the brick body.

[0034] Adjusting assembly, the adjusting assembly is arranged on the collar 11.

[0035] Through the above-mentioned features, the air outlet nozzle 20 can be adjusted according to the shape and size of the brick body, and the brick body machine can be heated. Specifically, the staff opens the tank door 7 through the vertical rotating shaft 6, places the brick body inside the brick body placement bin 10, and then seals the tank mouth 8 through the tank door 7, opens the brick heating steamer body 2, and allows hot steam to heat the brick body through the air outlet nozzle 20. The temperature sensor 21 on the upper connecting plate 14 can detect the temperature of the brick body. If the temperature sensor 21 detects that the temperature of the brick body is uneven, the staff can adjust the angle of the air outlet nozzle 20 by adjusting the electromagnet in the sphere 19.

[0036] As a preferred implementation in this embodiment, please refer to Figures 4 to 9As shown, the adjustment component includes: multiple circular iron blocks 22, which are respectively fixedly mounted on the left and right side walls of the multiple lower connecting plates 13, and a groove 23 is provided on the outer surface of the ring 11. Multiple circular electromagnets 24 are fixedly mounted on the inner wall of the groove 23, and the circular electromagnets 24 can cooperate with the circular iron blocks 22.

[0037] Through the above-mentioned features, the position of the air outlet nozzle 20 can be adjusted. Specifically, when the position of the air outlet nozzle 20 needs to be adjusted, or when multiple air outlet nozzles 20 need to be used to heat the brick body together, the staff can energize the circular electromagnets 24 in the groove 23 in turn, so that the circular iron block 22 moves on the outer surface of the ring 11 under the magnetic force of multiple circular electromagnets 24. When the circular iron block 22 moves, the lower connecting plate 13 and the upper connecting plate 14 will move with the movement of the circular iron block 22. When the upper connecting plate 14 moves, the sphere 19 and the air outlet nozzle 20 on the upper connecting plate 14 will move.

[0038] As a preferred implementation in this embodiment, please refer to Figures 6 to 9 As shown, the circulation parts include: a connecting chamber 15, which is fixedly installed on the bottom surface of the lower connecting plate 13, a heating pipe 16 is provided on the bottom surface of the connecting chamber 15, and a heating pipe 2 17 is provided on the side wall of the connecting chamber 15, and the other end of the heating pipe 2 17 is connected to the interior of the sphere 19.

[0039] Through the above-mentioned features, the hot steam in the steam pipe in the brick heating steamer body 2 is ejected through the gas outlet nozzle 20. Specifically, the hot steam in the steam pipe in the brick heating steamer body 2 flows into the connecting chamber 15 through the heating pipe 16, and then flows from the connecting chamber 15 into the sphere 19 through the heating pipe 2 17. Since the sphere 19 and the interior of the gas outlet nozzle 20 are interconnected, the hot steam in the interior of the sphere 19 will be ejected from the interior of the gas outlet nozzle 20.

[0040] As a preferred implementation in this embodiment, please refer to Figure 8 As shown, a mounting groove 25 is provided on the top surface of the lower connecting plate 13 , and an electric push rod 26 is fixedly installed inside the mounting groove 25 . The output end of the electric push rod 26 is fixedly connected to the bottom surface of the upper connecting plate 14 .

[0041] Through the above features, the air outlet nozzle 20 is extended to make it close to the brick body. Specifically, when the air outlet nozzle 20 needs to be close to the brick body, the staff starts the electric push rod 26 in the lower connecting plate 13. When the electric push rod 26 is started, the upper connecting plate 14 connected to the output end of the electric push rod 26 is extended. When the upper connecting plate 14 is extended, the ball 19 and the air outlet nozzle 20 are extended. If the air outlet nozzle 20 needs to be returned to its original position, it is only necessary to retract the electric push rod 26.

[0042] It is worth mentioning that, angle adjustment: the processor 5 controls the electromagnet in the spherical groove 18 to turn on and off, changes the adsorption force on the sphere 19, deflects the air outlet nozzle 20 within the range of ±30°, and adjusts the direction of hot air injection.

[0043] Position adjustment: The circular electromagnets 24 are energized in sequence, attracting the circular iron block 22 to move along the groove 23 of the collar 11 , driving the lower connecting plate 13 and the upper connecting plate 14 to move horizontally, thereby adjusting the horizontal coverage of the air outlet nozzle 20 .

[0044] Distance adjustment: Start the electric push rod 26 to push the upper connecting plate 14 toward the brick body, shortening the distance between the air outlet nozzle 20 and the brick body to 50-100mm, thereby enhancing the local heating effect; after completion, the electric push rod 26 is reset;

[0045] In addition, when the temperature at the bottom of the brick storage bin 10 is low, the processor 5 performs the following actions:

[0046] The electromagnetic rod 28 is turned on, and the fixed iron block 27 moves down along the slide groove of the electromagnetic rod 28, driving the entire ring 11 to move down 30 mm, so that the air outlet nozzle 20 is aligned with the bottom brick body.

[0047] Start the electric push rod 26 at the corresponding position to extend the air outlet nozzle 20 by 80 mm, and at the same time adjust the angle of the sphere 19 to 15 degrees to concentrate the hot air to cover the low temperature area.

[0048] After the above adjustment is completed, the temperature sensor 21 continues to monitor until the temperature of each area of the brick body reaches the standard uniformly.

[0049] As a preferred implementation in this embodiment, please refer to Figure 4 and Figure 9 As shown, fixed iron blocks 27 are fixedly installed on the front and rear sides of the inner walls of multiple upper rings 11, and sliding grooves are provided on the side walls of the fixed iron blocks 27. Electromagnetic rods 28 are fixedly installed on the support columns 9 on the front and rear side walls of the tank mouth 8. The electromagnetic rods 28 pass through the sliding grooves on the fixed iron blocks 27, and the fixed iron blocks 27 can slide on the electromagnetic rods 28.

[0050] With the above features, when the position of the collar 11 needs to be adjusted, the staff can turn on the electromagnetic rod 28 to move the fixed iron block 27 on the electromagnetic rod 28. When the fixed iron block 27 moves, the collar 11 will move accordingly.

[0051] It is worth mentioning that 29 makes the fixed iron block 27 move, the electromagnet in the spherical groove 18 makes the ball 19 adjust, and the circular electromagnet 24 makes the circular iron block 22 move, which are all existing mature technical means and therefore will not be described in detail in the present invention.

[0052] As a preferred implementation in this embodiment, please refer to Figures 1 to 3 As shown, a controller 3 is fixedly installed on the front side wall of the support base 1, a distribution box 4 is fixedly installed on the front side wall of another support base 1, and a processor 5 is fixedly installed on the rear side wall of one of the support bases 1. After the heating is completed, the steam supply is turned off, and after the pressure in the steam tank returns to zero, the tank door 7 is staggered to take out the brick body.

[0053] Regularly check the circuit connections of the circular electromagnet 24 and the electric push rod 26 to ensure that the adjustment components are sensitive and reliable; clean the scale on the inner wall of the air outlet nozzle 20 to prevent blockage.

[0054] Working principle:

[0055] During operation, the operator rotates the vertical shaft 6 to open the tank door 7, neatly stacks the fly ash autoclaved bricks to be heated into the brick storage bin 10, closes the tank door 7 so that it completely covers the tank opening 8, and secures the brick storage bin 10 with support columns 9 to ensure the bricks are stable during the heating process. At this point, the interior of the steamer forms a sealed space, preventing heat loss. The controller 3 is activated, and the distribution box 4 supplies power to the system. Upon receiving the command, the processor 5 activates the steam pipes within the brick heating steamer body 2. Hot steam flows through heating pipe 16 into the connecting bin 15, then through heating pipe 2 17 to the interior of the sphere 19, ultimately ejecting vertically from the air outlet nozzle 20. Initially, the electromagnet in the spherical groove 18 attracts the sphere 19, securing the air outlet nozzle 20 at a vertical angle (0°), ensuring uniform coverage of the brick surface with hot air. A temperature sensor 21 on the top of the upper connecting plate 14 monitors the brick surface temperature in real time and feeds the data back to the processor 5. If the detected temperature difference exceeds a set threshold (±5°C), the system automatically triggers the regulation mechanism. The processor 5 controls the on and off of the electromagnet in the spherical groove 18, changes the adsorption force on the sphere 19, and causes the air outlet nozzle 20 to deflect within the range of ±30°. For example, when the temperature at the top of the brick body is too high, the air outlet nozzle 20 tilts downward by 15° to concentrate the hot air to the low-temperature area at the bottom. The circular electromagnet 24 is energized in turn, attracting the circular iron block 22 to move horizontally along the groove 23 of the collar 11, driving the lower connecting plate 13 and the upper connecting plate 14 to move, thereby adjusting the horizontal coverage range of the air outlet nozzle 20. For example, the moving distance can reach 50mm to eliminate the side heating dead angle. Start the electric push rod 26, push the upper connecting plate 14 out toward the brick body, shorten the distance between the air outlet nozzle 20 and the brick body to 50-100mm, and enhance the local hot air intensity. After the adjustment is completed, the electric push rod 26 retracts to its initial position. When the temperature at the bottom of the brick placement bin 10 is low, the processor 5 turns on the electromagnetic rod 28, and the fixed iron block 27 moves down 30mm along the slide groove of the electromagnetic rod 28, driving the collar 11 to move down as a whole, so that the air outlet nozzle 20 is aligned with the bottom brick. Synchronously start the electric push rod 26 at the corresponding position, extend the air outlet nozzle 20 by 80mm, and adjust the angle of the sphere 19 to 15° to concentrate hot air to cover the low-temperature area. The temperature sensor 21 continuously monitors until the temperature of each area is uniform and meets the standard (temperature difference ≤±3℃). After heating is completed, the processor 5 turns off the steam supply, and after the pressure in the steam tank returns to zero, open the tank door 7 to remove the brick. Regularly check the circuit connection of the circular electromagnet 24 and the electric push rod 26 to ensure the adjustment sensitivity; clean the scale on the inner wall of the air outlet nozzle 20 to prevent blockage.

[0056] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
