Description

Technical Field

[0001] This invention relates to the field of fly ash autoclaved brick technology, specifically a heating device for the production of fly ash autoclaved bricks. Background Technology

[0002] Autoclaved fly ash bricks are fly ash bricks made primarily from fly ash, lime, or cement, with the addition of appropriate amounts of gypsum and aggregates. The mixture is prepared, pressed, and cured under high pressure, normal pressure, or naturally. Fly ash bricks, made primarily from fly ash and lime, with the addition of appropriate amounts of gypsum and aggregates, are prepared, pressed, and cured under high pressure steam. There are two types: non-autoclaved fly ash bricks and autoclaved fly ash bricks. Autoclaved fly ash bricks are made by high-pressure steam curing. Autoclaved fly ash bricks are made by steam curing under normal pressure. The raw materials and manufacturing processes are basically the same for both types; the difference lies in the curing process and their properties. Autoclaved fly ash bricks are cured under saturated steam pressure (steam temperature above 174.5℃, working pressure above 0.8MPa), allowing the active components in the brick to undergo a full hydrothermal reaction, resulting in high strength and stable performance. While autoclaved fly ash bricks may experience cracking issues common in walls, they generally have higher compressive strength, reaching 20MPa or 15MPa, and at least 10MPa, meeting the requirement of withstanding 15 freeze-thaw cycles. Furthermore, fly ash bricks are a potentially active hydraulic material; in humid environments, they continue to undergo hydration reactions, making the internal structure of the brick denser and contributing to increased strength.

[0003] First, during the heating process, the inconsistent shape and size of fly ash autoclaved bricks, along with uneven airflow distribution within the heating device, prevents heat from being evenly distributed to each brick. This uneven heat distribution is particularly pronounced in actual production, resulting in poor heating of some bricks and consequently affecting product quality. For example, the fixed hot air inlet of traditional devices creates dead zones in the hot air distribution, leading to uneven heating of the bricks. If the top is sufficiently heated but the bottom or sides are insufficiently heated, internal stress cracks can easily occur, severely impacting the strength and service life of the bricks. Second, while some existing technologies attempt to improve hot air distribution by increasing the number of hot air nozzles or adjusting their positions, these methods cannot fundamentally solve the problem of dead zones in hot air distribution, and the adjustment methods are complex and difficult to precisely adjust according to the actual shape and size of the bricks. Furthermore, the fixed position and angle of the hot air nozzles in traditional heating devices cannot be dynamically adjusted according to the shape and size of the bricks, resulting in low heating efficiency and significant energy waste. Finally, traditional heating devices have a low degree of automation and lack real-time monitoring and feedback adjustment functions. During the heating process, it is impossible to monitor the temperature changes on the brick surface in real time, nor can the direction and intensity of hot air jets be automatically adjusted according to temperature differences, resulting in poor controllability of the heating process and large fluctuations in product quality.

[0004] Therefore, based on the above-mentioned search and combined with existing technologies, a heating device for the production of fly ash autoclaved bricks is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a heating device for the production of autoclaved bricks from fly ash, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A heating device for producing autoclaved bricks from fly ash includes: two support bases, on the top surfaces of which a brick heating steam tank body is fixedly mounted; a tank door is rotatably connected to the left side wall of the brick heating steam tank body via a vertical rotating shaft; a tank opening is formed on the left side wall of the brick heating steam tank body; the tank door can close or completely offset the tank opening; a brick placement chamber is fixedly mounted inside the tank opening via multiple support columns; and multiple sets of hot gas ejection components are respectively arranged on the tank opening. The hot gas ejection components include... The hot gas ejection assembly includes: a collar, which is disposed on the tank opening; a circular groove is formed on the inner wall of the collar; a lower connecting plate is disposed on the inner wall of the groove; an upper connecting plate is disposed on the top surface of the lower connecting plate; the upper connecting plate is T-shaped; a spherical groove is formed on the top surface of the upper connecting plate; a sphere is movably installed inside the spherical groove; an exhaust nozzle is fixedly installed on the top of the sphere; the interior of the sphere communicates with the exhaust nozzle; a temperature sensor is fixedly installed on the top surface of the upper connecting plate; and a flow element is also included in the hot gas ejection assembly. An adjustment assembly is disposed on the collar.

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

[0009] Furthermore, the flow component includes: a connecting compartment, which is fixedly installed on the bottom surface of the lower connecting plate. A heating pipe is provided on the bottom surface of the connecting compartment, and a heating pipe is provided on the side wall of the connecting compartment. The other end of the heating pipe is connected to the interior of the sphere.

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

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

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

[0013] Furthermore, a controller is fixedly installed on the front side wall of one of the support bases, and a distribution box is fixedly installed on the front side wall of the other 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 beneficial effects of the present invention are:

[0016] 1. By incorporating multiple sets of hot steam ejection and adjustment components, the problem of uneven heat distribution in traditional fly ash autoclaved brick heating devices can be effectively solved. The hot steam ejection component includes key components such as adjustable-angle air nozzles, spheres, spherical grooves, and temperature sensors, which can automatically adjust the direction and intensity of hot air injection according to the shape and size of the brick. The air nozzles achieve multi-angle deflection through the cooperation of the sphere and spherical groove, with an adjustment range of ±30°, ensuring that the hot air can accurately cover all parts of the brick and avoid heating dead zones caused by irregular shapes or size differences. At the same time, the circular electromagnet and circular iron block in the adjustment component work together to achieve flexible adjustment of the horizontal position, further optimizing the distribution range of hot air. In addition, the temperature sensor monitors the surface temperature of the brick in real time and feeds the data back to the processor. The system automatically triggers the adjustment mechanism based on the monitoring results, dynamically adjusting the angle and position of the air nozzles to ensure uniform temperature in all areas of the brick. This intelligent and dynamic adjustment method not only improves heating efficiency but also significantly enhances product quality, effectively avoids internal stress cracks caused by local overheating or underheating, extends the service life of the bricks, and provides a more efficient and reliable heating solution for the production of fly ash autoclaved bricks.

[0017] 2. By incorporating mechanical structures such as electric actuators, electromagnetic rods, and fixed iron blocks, this invention demonstrates significant advantages in adjusting the hot air jet distance and coverage area. The telescopic function of the electric actuator allows the air nozzle to flexibly adjust its distance from the brick according to the actual needs of the brick. For example, when enhanced local heating is required, the electric actuator can push the air nozzle outward, shortening the distance between it and the brick to 50-100mm, thereby concentrating hot air to cover low-temperature areas and improving heating efficiency. Simultaneously, the combined use of the electromagnetic rod and the fixed iron block enables the overall vertical movement of the collar, further optimizing the vertical position of the air nozzle and ensuring that hot air can evenly cover the bottom bricks of the brick placement chamber. This synergistic effect of the mechanical structures not only improves the utilization efficiency of hot air but also avoids the problem of insufficient bottom or side heating common in traditional fixed nozzle designs.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] In one typical embodiment of this application, please refer to Figures 1-9 As shown, a heating device for producing fly ash autoclaved bricks includes: a support base 1, of which two support bases 1 are provided. A brick heating autoclave body 2 is fixedly installed on the top surface of the two support bases 1. The support bases 1 support the brick heating autoclave body 2. A tank door 7 is rotatably connected to the left side wall of the brick heating autoclave body 2 via a vertical rotating shaft 6. A tank opening 8 is provided on the left side wall of the brick heating autoclave body 2. The tank door 7 can be closed or completely offset. It is closed during brick heating and offset after heating. A brick placement chamber 10 is fixedly installed inside the tank opening 8 via multiple support columns 9. The brick placement chamber 10 is used to place bricks. The operator rotates the vertical rotating shaft 6 to open the tank door 7 and neatly stacks the fly ash autoclaved bricks to be heated into the brick placement chamber 10. Figure 4 Close the tank door 7 to completely cover the tank opening 8, ensuring the interior of the steam tank is sealed. At this time, the support column 9 secures the brick placement chamber 10 to prevent the bricks from shifting during heating;

[0030] A hot gas ejection assembly, comprising multiple sets, is provided on the tank opening 8. The hot gas ejection assembly includes:

[0031] A collar 11 is mounted on the tank opening 8. A circular groove 12 is formed on the inner wall of the collar 11. A lower connecting plate 13 is mounted on the inner wall of the groove 12. An upper connecting plate 14, which is T-shaped, is mounted on the top surface of the lower connecting plate 13. A spherical groove 18 is formed on the top surface of the upper connecting plate 14. A sphere 19 is movably mounted inside the spherical groove 18. Multiple electromagnets are mounted on the inner wall of the spherical groove 18, which can adjust the attraction of the sphere 19. An exhaust nozzle 20 is fixedly mounted on the top of the sphere 19, and the interior of the sphere 19 communicates with the exhaust nozzle 20. A temperature sensor 21 is fixedly mounted 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 the data back to the processor 5. If the detected temperature difference exceeds a set threshold (e.g., ±5℃), the system automatically triggers an adjustment mechanism. The hot steam ejection assembly also includes a flow-through component.

[0032] Controller 3 is activated, and power distribution box 4 supplies power to the system. After receiving the instruction, processor 5 activates the steam pipe inside the brick heating steamer body 2, and hot steam enters the connecting chamber 15 through heating pipe 16.

[0033] Hot steam is transported to the interior of the sphere 19 via heating pipe 2 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 attraction of the electromagnet in the spherical groove 18, ensuring that the hot air is sprayed vertically onto the brick.

[0034] Adjustment component, the adjustment component is set on collar 11.

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

[0036] As a preferred embodiment of this example, please refer to [link / reference]. Figures 4-9As shown, the adjustment assembly includes: multiple circular iron blocks 22, which are fixedly installed on the left and right side walls of multiple lower connecting plates 13 respectively. The outer surface of the collar 11 is provided with a groove 23, and multiple circular electromagnets 24 are fixedly installed on the inner wall of the groove 23. The circular electromagnets 24 can cooperate with the circular iron blocks 22.

[0037] Based on the above features, the position of the air nozzle 20 can be adjusted. Specifically, when it is necessary to adjust the position of the air nozzle 20, or to heat the brick body with multiple air nozzles 20 at the same time, the operator can sequentially energize the circular electromagnets 24 in the groove 23, so that the circular iron block 22 moves on the outer surface of the collar 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 along with the circular iron block 22. When the upper connecting plate 14 moves, the ball 19 on the upper connecting plate 14 and the air nozzle 20 will move.

[0038] As a preferred embodiment of this example, please refer to [link / reference]. Figures 6-9 As shown, the flow component includes: 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 17 is provided on the side wall of the connecting chamber 15. The other end of the heating pipe 17 is connected to the interior of the sphere 19.

[0039] Based on the above features, the hot steam in the steam pipe of the brick heating steam tank body 2 is ejected through the air outlet nozzle 20. Specifically, the hot steam in the steam pipe of the brick heating steam tank 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 17. Since the sphere 19 and the interior of the air outlet nozzle 20 are interconnected, the hot steam inside the sphere 19 will be ejected from the interior of the air outlet nozzle 20.

[0040] As a preferred embodiment of this example, please refer to [link / reference]. Figure 8 As shown, the top surface of the lower connecting plate 13 is provided with a mounting groove 25, and an electric actuator 26 is fixedly installed inside the mounting groove 25. The output end of the electric actuator 26 is fixedly connected to the bottom surface of the upper connecting plate 14.

[0041] Using the above features, the air nozzle 20 is extended to be close to the brick. Specifically, when it is necessary to bring the air nozzle 20 close to the brick, the operator activates the electric actuator 26 in the lower connecting plate 13. When the electric actuator 26 is activated, the upper connecting plate 14 connected to the output end of the electric actuator 26 will extend. When the upper connecting plate 14 extends, both the ball 19 and the air nozzle 20 will extend. If it is necessary to return the air nozzle 20 to its original position, the electric actuator 26 can be retracted.

[0042] It is worth mentioning that the angle adjustment is as follows: the processor 5 controls the electromagnet in the spherical groove 18 to switch on and off, changing the attraction force on the ball 19, so that the air nozzle 20 deflects within a range of ±30°, and adjusts the direction of hot air jet.

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

[0044] Distance adjustment: Activate the electric actuator 26 to push the upper connecting plate 14 to extend towards the brick, thereby shortening the distance between the air nozzle 20 and the brick to 50-100mm and enhancing the local heating effect; after completion, the electric actuator 26 returns to its original position.

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

[0046] When the electromagnetic rod 28 is activated, the fixed iron block 27 moves down along the slide groove of the electromagnetic rod 28, causing the collar 11 to move down 30mm as a whole, so that the air nozzle 20 is aligned with the bottom brick.

[0047] Activate the electric actuator 26 at the corresponding position to extend the air nozzle 20 by 80mm, and at the same time adjust the angle of the ball 19 to tilt to 15° to concentrate hot air to cover the low-temperature area.

[0048] After the above adjustments are completed, the temperature sensor 21 continues to monitor until the temperature in all areas of the brick reaches the standard uniformly.

[0049] As a preferred embodiment of this example, please refer to [link / reference]. Figure 4 and Figure 9 As shown, fixed iron blocks 27 are fixedly installed on the front and rear sides of the inner wall of multiple upper rings 11. The side walls of the fixed iron blocks 27 are provided with sliding grooves. Electromagnetic rods 28 are fixedly installed on the support columns 9 on the front and rear side walls of the can opening 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] Based on the above features, when it is necessary to adjust the position of the collar 11, the operator can move the fixed iron block 27 on the electromagnetic rod 28 by turning on the electromagnetic rod 28. When the fixed iron block 27 moves, the collar 11 will move accordingly.

[0051] It is worth mentioning that the movement of the fixed iron block 27 by 29, the adjustment of the ball 19 by the electromagnet in the spherical groove 18, and the movement of the circular iron block 22 by the circular electromagnet 24 are all existing mature technologies, and therefore will not be described in detail in this invention.

[0052] As a preferred embodiment of this example, please refer to [link / reference]. Figures 1-3 As shown, a controller 3 is fixedly installed on the front side wall of support 1, a distribution box 4 is fixedly installed on the front side wall of another support 1, and a processor 5 is fixedly installed on the rear side wall of one of the support 1s. After heating is completed, the steam supply is turned off, and after the pressure inside the steam tank returns to zero, the tank door 7 is opened to remove the brick.

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

[0054] Working principle:

[0055] During operation, the operator opens the tank door 7 by rotating the vertical shaft 6, neatly stacks the fly ash autoclaved bricks to be heated in the brick placement chamber 10, closes the tank door 7 to completely cover the tank opening 8, and uses the support column 9 to fix the brick placement chamber 10 to ensure the stability of the bricks during heating. At this time, a sealed space is formed inside the autoclave to prevent heat loss. The controller 3 is started, and the power distribution box 4 supplies power to the system. After receiving the command, the processor 5 activates the steam pipe inside the brick heating autoclave body 2. Hot steam enters the connecting chamber 15 through the first heating pipe 16, and then is transported to the inside of the sphere 19 through the second heating pipe 17, and finally sprayed vertically from the air outlet nozzle 20. In the initial state, the electromagnet in the spherical groove 18 attracts the sphere 19, fixing the angle of the air outlet nozzle 20 to the vertical direction (0°), ensuring that the hot air evenly covers the surface of the brick. The temperature sensor 21 on the top of the upper connecting plate 14 monitors the surface temperature of the brick in real time and feeds the data back to the processor 5. If the detected temperature difference exceeds the set threshold (±5℃), the system automatically triggers the adjustment mechanism. The processor 5 controls the on / off switching of the electromagnets in the spherical groove 18, changing the attraction force on the sphere 19 and causing the air nozzle 20 to deflect within a range of ±30°. For example, when the temperature at the top of the brick is too high, the air nozzle 20 tilts downwards by 15°, concentrating the hot air into the lower, lower-temperature area. The circular electromagnets 24 are sequentially energized, attracting the circular iron block 22 to move horizontally along the groove 23 of the collar 11, causing the lower connecting plate 13 and the upper connecting plate 14 to shift, thereby adjusting the horizontal coverage of the air nozzle 20. For example, the movement distance can reach 50mm to eliminate side heating dead zones. The electric actuator 26 is activated, pushing the upper connecting plate 14 towards the brick, shortening the distance between the air nozzle 20 and the brick to 50-100mm, enhancing the localized hot air intensity. After adjustment, the electric actuator 26 retracts to its initial position. When the bottom temperature of the brick placement chamber 10 is low, the processor 5 activates the electromagnetic rod 28, causing the fixed iron block 27 to move 30mm down along the groove of the electromagnetic rod 28, which in turn moves the collar 11 down, aligning the air nozzle 20 with the bottom brick. Simultaneously, the corresponding electric actuator 26 is activated, extending the air nozzle 20 80mm and adjusting the angle of the ball 19 to 15° to concentrate hot air over the low-temperature area. The temperature sensor 21 continuously monitors until the temperature in each area is uniformly within the acceptable range (temperature difference ≤ ±3℃). After heating is complete, the processor 5 shuts off the steam supply. Once the pressure inside the steam tank reaches zero, the tank door 7 is opened to remove the brick. Regularly check the wiring connections of the circular electromagnet 24 and the electric actuator 26 to ensure adjustment sensitivity; clean the scale from the inner wall of the air nozzle 20 to prevent blockage.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
