Description

Technical Field

[0001] This invention relates to the field of energy-saving building material production technology, and in particular to an autoclaved aerated concrete block molding device. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are porous concrete products made from fly ash, lime, cement, gypsum, slag, and other main raw materials, with the addition of appropriate amounts of foaming agents, regulators, and bubble stabilizers. They are produced through processes such as batching and mixing, pouring, static curing, cutting, and high-pressure autoclaving. AAC blocks are a new type of green, energy-saving, environmentally friendly, and waste-utilizing wall material. The AAC block forming process is pouring, cutting, and autoclaving.

[0003] Autoclaving of autoclaved aerated concrete blocks involves placing them directly onto a support plate inside an autoclave, where the internal space remains constant. However, this method has the following drawbacks: 1. The constant internal space of the autoclave means that regardless of the number of autoclaved aerated concrete blocks placed inside, the pressure inside the autoclave must be raised to 0.8-1.2MPa and the temperature to 174-190℃, and maintained at a constant temperature and pressure for 8-12 hours. As a result, when the number of blocks placed is small, the steam consumption, heating energy and production time are not reduced accordingly, resulting in a waste of energy and time resources. 2. The part of the autoclaved aerated concrete block that contacts the side wall of the load-bearing plate forms a "contact blind zone". Saturated steam cannot fully penetrate into this area, resulting in insufficient local hydrothermal synthesis reaction. This can easily lead to quality defects such as local looseness, color difference, and even micro-cracks, affecting the uniformity of the overall performance of the block. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing technology has the disadvantages of energy waste during autoclaving and insufficient local hydrothermal synthesis reaction of blocks. To this end, we propose an autoclaved aerated concrete block forming device.

[0009] Preferably, the L-shaped plate is provided with a clamping mechanism, which includes an annular groove formed on the side wall away from the fixed frame. A rotating ring is slidably connected to the inner wall of the annular groove. A second U-shaped plate is fixedly connected to the outer wall of the ring. The autoclaved aerated concrete block is located on the inner wall of the second U-shaped plate. Sliding grooves are formed on both inner walls of the second U-shaped plate. Clamping plates are slidably connected to the inner walls of the two sliding grooves. The side walls of the clamping plates are elastically connected to the inner walls of the sliding grooves through multiple second springs. The inner walls of the two sliding grooves are fixedly connected to the side wall of the ring located in the annular groove through connecting pipes.

[0015] The technical effects and advantages of this invention are as follows: 1. The present invention can adjust the position of the regulating plate according to the number of blocks inside the autoclave, thereby adjusting the space inside the autoclave. This avoids the waste of energy and time resources caused by the prior art, which requires raising the pressure inside the autoclave to 0.8-1.2MPa and the temperature to 174-190℃ and maintaining a constant temperature and pressure for 8-12 hours, regardless of the number of blocks placed inside the autoclave.

[0016] 2. This invention can increase the pressure inside the strip cavity while the block is clamped, causing the T-shaped rod and the first U-shaped plate to move on the lower surface of the block, changing the support position on the lower surface of the block, thereby performing regional curing on the lower surface of the block, increasing the curing effect of the block, and avoiding the "contact blind zone" in the curing of blocks in the prior art, which leads to insufficient local hydrothermal synthesis reaction, easily causing local looseness, color difference, or even micro-cracks and other quality defects, affecting the uniformity of the overall performance of the block.

[0017] 3. The present invention can drive the motor to rotate forward while the block is clamped and the side wall of the first U-shaped plate is in contact with the side wall of the L-shaped plate. The motor then drives the second U-shaped plate to rotate forward half a turn through the one-way bearing, thereby causing the clamped block to rotate forward half a turn. This allows for the replacement of the block's upper and lower positions, thus avoiding uneven heat transfer during the block curing process. Attached Figure Description

[0020] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0021] Reference Figures 1-11 An autoclaved aerated concrete block forming device includes an autoclave 1. The upper end of the autoclave 1 is detachably and sealed with an autoclave door 2 by multiple bolts. A control panel 3 is installed on the side wall of the autoclave 1 to display the temperature and pressure inside the autoclave 1, ensuring that the pressure inside the autoclave 1 is 0.8-1.2MPa and the temperature is 174-190℃.

[0022] The air intake mechanism includes an air intake pipe 4. Multiple U-shaped pipes 6 are fixedly connected to the bottom of the autoclave 1. The bottom of each U-shaped pipe 6 is fixedly connected to the top of the air intake pipe 4 through a rigid pipe 5. A first solenoid valve 9 is installed in each of the multiple rigid pipes 5. Furthermore, the air intake pipe 4 is fixedly connected to an external steam generator for supplying steam into the autoclave 1.

[0023] Multiple sets of support mechanisms, each of which includes two fixed frames 7 that are fixedly connected to the inner wall of the autoclave 1. The two fixed frames 7 face each other. Furthermore, the side walls of the two fixed frames 7 that are close to each other are flush with the inner wall of the autoclave 1. Multiple U-shaped tubes 6 correspond one-to-one with the multiple sets of support mechanisms.

[0024] The adjustment mechanism includes two multi-stage electric push rods 10 fixedly connected to the side wall of the autoclave 1. The output ends of the two multi-stage electric push rods 10 are fixedly connected to an adjustment plate 11. The side wall of the adjustment plate 11 is slidably connected to the inner wall of the autoclave 1. Laser sensors 8 are fixedly connected to the bottom of the autoclave 1 between multiple sets of bearing mechanisms to measure the distance between the laser sensors 8 and the lower end of the autoclaved aerated concrete block. The upper end of the adjustment plate 11 is tightly fitted to the lower end of the autoclave door 2.

[0025] It should be noted that the upper end of the adjusting plate 11 is equipped with a sealing gasket to increase the sealing between it and the lower end of the vessel door 2.

[0026] The lower end of the adjustment plate 11 has a first slot 12 that is directly opposite the laser sensor 8 (e.g., Figure 3 As shown), a second groove 13 is opened at the top of the first groove 12. A partition 14 is slidably connected to the inner wall of the second groove 13. The upper end of the partition 14 is elastically connected to the top of the second groove 13 through multiple magnetic springs 15. The multi-stage electric push rod 10 and multiple magnetic springs 15 are electrically connected through an external first controller.

[0027] After the magnetic spring 15 is energized, due to electromagnetic induction, the magnetic spring 15 interacts with the current in the external magnetic field to generate different magnitudes of tension, thereby controlling the tensile deformation and movement state of the magnetic spring 15. Since there are relatively few autoclaved aerated concrete blocks placed inside the autoclave 1, that is, relatively few autoclaved aerated concrete blocks (hereinafter collectively referred to as blocks) located on the multiple sets of bearing mechanisms, the two multi-stage electric push rods 10 are extended. At this time, the external first controller energizes multiple magnetic springs 15 (this control method is a common electrical control method and is existing technology). The multiple magnetic springs 15 contract, driving the partition... 14 moves upward and is entirely within the second groove 13 (it should be noted that the top of the second groove 13 has a through hole communicating with the outside, used to balance the pressure change within the second groove 13 when the partition 14 slides). Then the adjusting plate 11 can move within the autoclave 1. During the movement, the laser sensor 8 passes through the first groove 12. When the adjusting plate 11 moves to the designated position (near the placed block), the multi-stage electric push rod 10 is de-energized, and the external first controller de-energizes multiple magnetic springs 15, causing the partition 14 to move downward to the initial position under the elastic force of multiple magnetic springs 15, sealing the first groove 12.

[0028] At the same time, after the position of the regulating plate 11 is adjusted, the first solenoid valve 9 corresponding to the rigid pipe 5 located between the multi-stage electric push rod 10 and the regulating plate 11 is de-energized and closed, preventing subsequent steam from entering the area.

[0029] In this way, the position of the adjusting plate 11 can be moved according to the number of blocks inside the autoclave 1 to adjust the space inside the autoclave 1. This avoids the waste of energy and time resources caused by the existing technology, which requires raising the pressure inside the autoclave to 0.8-1.2MPa and the temperature to 174-190℃ and maintaining a constant temperature and pressure for 8-12 hours, regardless of the number of blocks placed inside the autoclave 1.

[0030] An L-shaped plate 16 is slidably connected to the inner wall of the fixed frame 7. Two cylinders 17 are fixedly connected to the side wall of the fixed frame 7. The output ends of the two cylinders 17 are fixedly connected to the side wall of the L-shaped plate 16. A strip cavity 18 is opened on the lower inner wall of the L-shaped plate 16 away from the fixed frame 7. A T-shaped rod 19 is slidably connected to the inner wall of the strip cavity 18. The side wall of the T-shaped rod 19 away from the strip cavity 18 is connected to a first U-shaped plate 20 through a sliding mechanism. The autoclaved aerated concrete block is located on the inner side wall of the first U-shaped plate 20. The side wall of the T-shaped rod 19 away from the first U-shaped plate 20 is elastically connected to the inner wall of the strip cavity 18 through multiple first springs 23. The inner wall of the strip cavity 18 near the first springs 23 is connected to an external oil pump through a first oil inlet pipe 24. It should be noted that the side wall of the T-shaped rod 19 penetrates the inner wall of the strip cavity 18 near the first U-shaped plate 20. There is a gap at the connection between the two, which will not affect the normal sliding of the T-shaped rod 19.

[0031] The L-shaped plate 16 is provided with a clamping mechanism, which includes an annular groove 25 formed on the upper side wall away from the fixed frame 7 (e.g., Figure 6 As shown), a rotating ring 26 is slidably connected to the inner wall of the annular groove 25. A second U-shaped plate 27 is fixedly connected to the outer wall of the ring 26. The autoclaved aerated concrete block is located on the inner wall of the second U-shaped plate 27. Sliding grooves 28 are provided on both inner walls of the second U-shaped plate 27. Clamping plates 29 are slidably connected to the inner walls of the two sliding grooves 28. The side walls of the clamping plates 29 are elastically connected to the inner walls of the sliding grooves 28 through multiple second springs 30. The inner walls of the two sliding grooves 28 are fixedly connected to the side walls of the ring 26 located in the annular groove 25 through connecting pipes 31.

[0032] The inner wall of the autoclave 1 is provided with multiple first placement slots 41 that correspond one-to-one with multiple first molded plates 20 (e.g., Figure 9 As shown), a second placement groove 42 corresponding to the first U-shaped plate 20 is provided through the bottom of the fixed frame 7 (as shown). Figure 9 and Figure 10 (As shown).

[0033] During autoclaving of the blocks, the sidewalls of the blocks are located between two first U-shaped plates 20 and two second U-shaped plates 27 facing each other. When there are not many blocks to be autoclaved in the autoclave 1, the multiple cylinders 17 near the adjusting plate 11 are adjusted to contract according to the number of blocks, so that the multiple L-shaped plates 16 drive all the components on them to slide into the corresponding fixed frame 7 in a sealed manner, thus not hindering the sliding of the subsequent adjusting plate 11, and realizing the space adjustment in the autoclave 1.

[0034] The inner wall of the first oil inlet pipe 24 is fixedly connected to the inner wall of the annular groove 25 through the second oil inlet pipe 40. A second solenoid valve 43 is installed inside the first oil inlet pipe 24, and a third solenoid valve 44 (e.g., ...) is installed inside the second oil inlet pipe 40. Figure 6 (As shown).

[0035] During autoclaving of the blocks, the sidewalls of the blocks are located between two first U-shaped plates 20 and two second U-shaped plates 27 facing each other. In the initial state, the inner sidewalls of the first U-shaped plates 20 wrap around the sidewalls of the blocks, affecting the curing effect of saturated steam in this area. However, the inner sidewalls of the second U-shaped plates 27 and the two clamping plates 29 are not in contact with the sidewalls of the blocks, so they do not affect the flow of saturated steam in this area. When the position of the first molded plate 20 needs to be adjusted during maintenance, the second solenoid valve 43 is de-energized and closed, while the third solenoid valve 44 is energized and opened. External hydraulic oil then enters the two sliding grooves 28 through the first oil inlet pipe 24, the second oil inlet pipe 40, the annular groove 25, and the two connecting pipes 31, increasing the pressure within the two sliding grooves 28. This causes the two clamping plates 29 to move closer together and clamp the sidewall of the block. Subsequently, the second solenoid valve 43 is energized and opened, while the third solenoid valve 44 is de-energized and closed. At this time, the two clamping plates 29 still clamp the sidewall of the block. The block is clamped, and at this time, external hydraulic oil can enter the strip cavity 18 through the first oil inlet pipe 24, which increases the pressure inside the strip cavity 18. This causes the T-shaped rod 19 and the first U-shaped plate 20 to move on the lower surface of the block, changing the support position on the lower surface of the block. This allows for area-specific curing of the lower surface of the block, increasing the curing effect and avoiding the "contact blind zone" in the curing of blocks in the prior art. This can lead to insufficient local hydrothermal synthesis reaction, which can easily cause local looseness, color difference, or even micro-cracks and other quality defects, affecting the uniformity of the overall performance of the block.

[0036] The L-shaped plate 16 is provided with a rotating mechanism, which includes a one-way bearing 33. A motor 32 is fixedly connected to the side wall of the L-shaped plate 16. The side wall of the output shaft of the motor 32 is fixedly connected to the inner ring side wall of the one-way bearing 33, and the outer ring side wall of the one-way bearing 33 is fixedly connected to the side wall of the second U-shaped plate 27.

[0037] It should be noted that when the motor 32 rotates in the forward direction, the inner ring of the one-way bearing 33 drives its outer ring to rotate. When the motor 32 rotates in the reverse direction, the inner ring of the one-way bearing 33 does not drive its outer ring to rotate. During the block curing process, saturated steam enters from the bottom of the autoclave 1, resulting in a temperature difference between the top and bottom of the block. Therefore, during the curing process, the above steps can be repeated to clamp the block first. Then, hydraulic oil is absorbed through the strip cavity 18 in the first oil inlet pipe 24, causing the T-shaped rod 19 to move the first U-shaped plate 20 to fit against the side wall of the L-shaped plate 16. At this time, the first U-shaped plate 20 is away from the block. Then, the drive motor 32 rotates in the forward direction, driving the second U-shaped plate 27 to rotate half a turn in the forward direction through the one-way bearing 33, which in turn drives the clamped block to rotate half a turn in the forward direction. This changes the position of the block at the top and bottom, avoiding uneven heat transfer during the block curing process.

[0038] The sliding mechanism includes a groove 21 formed on the side wall of the first U-shaped plate 20. The side wall of the T-shaped rod 19 is slidably connected to the vertical inner wall of the groove 21. An electric push rod 22 is fixedly connected to the bottom of the groove 21. The output end of the electric push rod 22 is fixedly connected to the lower end of the T-shaped rod 19. The electric push rod 22 is electrically connected to its corresponding laser sensor 8 through an external second controller.

[0039] In the initial state, the height of the first molding plate 20 is as follows: Figure 5 As shown, the distance between the laser sensor 8 and the lower surface of the block is initially set to D1. After the position of the block is changed, the distance between the laser sensor 8 and the lower surface of the block is set to D2. Since the height of the block may vary each time it is cured, D2 may be greater than, equal to, or less than D1. The external second controller can then adjust the extension and retraction of the electric push rod 22 based on the data of D2. When D2 is greater than D1, the electric push rod 22 retracts; when D2 equals D1, the electric push rod 22 remains stationary. When D2 is less than D1, the electric push rod 22 extends, so that the inner bottom wall of the first U-shaped plate 20 remains flush with the lower surface of the block. Then, external hydraulic oil can enter the strip cavity 18 through the first oil inlet pipe 24, which increases the pressure in the strip cavity 18, squeezing the T-shaped rod 19 and the first U-shaped plate 20 to move the lower surface of the block, which can support the lower surface of the block. After the entire curing process changes the position of the block, it returns to the initial position. Then, the above steps are repeated to achieve uniform autoclaving on the block.

[0040] The upper end of the fixed frame 7 is sealed and fixedly connected to the sealing frame 34 (e.g.) Figure 6As shown), the side wall of the sealing frame 34 is connected to the side wall of the autoclave 1 through a sealing seal. The upper end of the L-shaped plate 16 is fixedly connected to a vertical plate 35 that matches the inner wall of the sealing frame 34. The side wall of the vertical plate 35 is rotatably connected to multiple impellers 37 through a rotating shaft 36. The multiple impellers 37 are close to the autoclaved aerated concrete blocks. The upper end of the L-shaped plate 16 has a third groove 38. The output shaft of the motor 32 is located in the third groove 38. The side wall of the output shaft of the motor 32 located in the third groove 38 and the side wall of the rotating shaft 36 are both fixedly connected to synchronous pulleys 39. A synchronous belt is connected between the two synchronous pulleys 39.

[0041] When the upper and lower positions of the blocks are not changed, the drive motor 32 rotates in the opposite direction. At this time, the two synchronous pulleys 39 and the synchronous belt drive the rotating shaft 36 and multiple impellers 37 to rotate, increasing the saturated steam flow above the side wall of the block and further increasing the uniform autoclaving on the block.

[0042] When autoclaving the blocks, the first step is to adjust the number of blocks to be autoclaved. If the number is small, the multiple cylinders 17 near the adjusting plate 11 are retracted, causing the multiple L-shaped plates 16 to slide their components into the corresponding fixed frame 7. Then, the two multi-stage electric push rods 10 are extended. At this time, the external first controller energizes the multiple magnetic springs 15, causing the multiple magnetic springs 15 to retract and move the partition 14 upwards, all of which are located in the second groove 13. Then, the adjusting plate 11 can move inside the autoclave 1. During the movement, the laser sensor 8 passes through the first groove 12. When the adjusting plate 11 moves to the designated position (near the placed block), the multi-stage electric push rods 10 are de-energized, and the external first controller de-energizes the multiple magnetic springs 15, causing the partition 14 to move downwards to the initial position under the elastic force of the multiple magnetic springs 15, sealing the first groove 12 and realizing the space adjustment inside the autoclave 1. At the same time, after the position of the regulating plate 11 is adjusted, the first solenoid valve 9 corresponding to the rigid pipe 5 located between the multi-stage electric push rod 10 and the regulating plate 11 is de-energized and closed, preventing subsequent steam from entering the area. The blocks requiring autoclaving are then placed on multiple sets of support mechanisms. In the initial state, the inner wall of the first U-shaped plate 20 wraps around the side wall of the block, affecting the curing effect of saturated steam in this area. The inner wall of the second U-shaped plate 27 and the two clamping plates 29 do not adhere to the side wall of the block, and will not affect the flow of saturated steam in this area. Subsequently, the staff sealed the connection between the autoclave 1 and the autoclave door 2 with multiple bolts. Then, the external steam generator entered the autoclave 1 through the air inlet pipe 4, the rigid pipe 5 corresponding to the block, and the U-shaped pipe 6 to steam and cure the block. At the same time, the control panel 3 was used to display the temperature and pressure inside the autoclave 1, ensuring that the pressure inside the autoclave 1 was 0.8-1.2MPa and the temperature was 174-190℃. When the position of the first U-shaped plate 20 needs to be adjusted during the maintenance process, the second solenoid valve 43 is de-energized and closed, and the third solenoid valve 44 is energized and opened. Then, external hydraulic oil will enter the two sliding grooves 28 through the first oil inlet pipe 24, the second oil inlet pipe 40, the annular groove 25 and the two connecting pipes 31 respectively, which increases the pressure in the two sliding grooves 28, causing the two clamping plates 29 to move closer to each other and clamp the side wall of the block. Then, the second solenoid valve 43 is energized and opened, and the third solenoid valve 44 is de-energized and closed. At this time, the two clamping plates 29 are still clamped to the side wall of the block, while external hydraulic oil can enter the strip cavity 18 through the first oil inlet pipe 24, which increases the pressure in the strip cavity 18, squeezing the T-shaped rod 19 and the first U-shaped plate 20 to move on the lower surface of the block, changing the support position of the lower surface of the block, thereby performing area maintenance on the lower surface of the block, increasing the maintenance effect of the block, and avoiding the "contact blind zone" in the block maintenance of the prior art; During the block curing process, saturated steam enters from the bottom of the autoclave 1, resulting in a temperature difference between the top and bottom of the block. Therefore, during the curing process, the above steps can be repeated to clamp the block first, and then hydraulic oil is absorbed through the strip cavity 18 in the first oil inlet pipe 24, causing the T-shaped rod 19 to move the first U-shaped plate 20 to fit against the side wall of the L-shaped plate 16. At this time, the first U-shaped plate 20 is away from the block, and the drive motor 32 rotates in the forward direction, driving the second U-shaped plate 27 to rotate half a turn in the forward direction through the one-way bearing 33, thereby causing the clamped block to rotate half a turn in the forward direction and changing the position of the block at the top and bottom. In the initial state, the height of the first molding plate 20 is as follows: Figure 5 As shown, the distance between the laser sensor 8 and the lower surface of the block is initially set to D1. After the position of the block is changed, the distance between the laser sensor 8 and the lower surface of the block is set to D2. Since the height of the block may vary each time it is cured, D2 may be greater than, equal to, or less than D1. The external second controller can then adjust the extension and retraction of the electric push rod 22 based on the data of D2. When D2 is greater than D1, the electric push rod 22 retracts; when D2 equals D1, the electric push rod 22 remains stationary. When D2 is less than D1, the electric push rod 22 extends, so that the inner bottom wall of the first U-shaped plate 20 always remains flush with the lower surface of the block. Then, external hydraulic oil can enter the strip cavity 18 through the first oil inlet pipe 24, which increases the pressure in the strip cavity 18, squeezing the T-shaped rod 19 and the first U-shaped plate 20 to move the lower surface of the block, which can support the lower surface of the block. After the entire curing process changes the position of the block above and below, it returns to the initial position. Then, the above steps can be repeated to achieve uniform autoclaving on the block. When the upper and lower positions of the blocks are not changed, the drive motor 32 rotates in the opposite direction. At this time, the two synchronous pulleys 39 and the synchronous belt drive the rotating shaft 36 and multiple impellers 37 to rotate, increasing the saturated steam flow above the side wall of the block and further increasing the uniform autoclaving on the block.
