Technical Field
[0001] This invention belongs to the field of autoclaved aerated concrete (AAC) panel production technology, specifically an AAC panel manufacturing equipment and production process. Background Technology
[0002] Autoclaved aerated concrete (AAC) panels produced by autoclaved aerated concrete (AAC) equipment can be used as main interior and exterior wall materials. It is a high-performance new type of wall building material. AAC panels are easy to construct, have a lower overall cost, and offer excellent environmental protection, thermal insulation, fire resistance, heat insulation, vibration damping, and sound insulation properties, making it one of the highest-performing wall materials. It is a porous silicate product made primarily from siliceous and calcareous materials, with the addition of a foaming agent. After mixing with water, a chemical reaction forms pores, which are then formed through processes such as casting, pre-oxidation cutting, and autoclaving.
[0003] However, existing autoclaved aerated concrete (AAC) panels, due to their stacked arrangement during autoclaving, create dead zones that cannot be properly cured. Furthermore, the curing chamber requires periodic depressurization, which is cumbersome. Therefore, improvements are needed. Summary of the Invention
[0004] The purpose of this invention is to provide an autoclaved aerated concrete (AAC) panel manufacturing equipment and production process to solve the problems mentioned in the background section.
[0005] To address the above problems, the present invention provides a technical solution: An autoclaved aerated concrete (AAC) panel manufacturing equipment includes a curing chamber, a rotary jetting mechanism, a pressure regulating and venting mechanism, a chamber cover, a buckle, a guide rail, a slider, a support plate, and a material support mechanism. The rotary jetting mechanism and the pressure regulating and venting mechanism are both located on the top of the curing chamber. A chamber cover is hinged to the curing chamber, and a buckle is hinged to the cover, engaging with the curing chamber. A guide rail is fixedly connected to the bottom inner side of the curing chamber, and a slider is slidably connected within the guide rail. A support plate is fixedly connected to the upper end of the slider, and a material support mechanism is mounted on the support plate.
[0006] Preferably, the bottom of the slider is provided with ball bearings, which contact the guide rail. The ball bearings reduce the friction between the slider and the guide rail.
[0007] Preferably, the rotary jet mechanism includes a motor, a connecting sleeve, an annular box, a vertical nozzle, a nozzle, a fixing rod, a sheath, an air supply pipe, an annular groove, and a through hole. The motor is installed at the top of the steam curing chamber, and the output shaft of the motor passes through the steam curing chamber and is rotatably connected to it. A connecting sleeve is installed on the output shaft by bolts. An annular box is fixedly connected to the bottom of the connecting sleeve, and a vertical nozzle is fixedly connected to the bottom of the annular box. Multiple evenly distributed nozzles are provided on both the vertical nozzle and the annular box. A sheath is rotatably connected to the outside of the annular box, and a fixing rod is fixedly connected to the sheath. The fixing rod is fixedly connected to the inner surface of the steam curing chamber. An air supply pipe is fixedly connected inside the sheath and enters the annular box. The air supply pipe passes through the steam curing chamber and extends to the outside of the steam curing chamber. Pressurized steam is delivered into the annular chamber through the air supply pipe. After passing through the annular groove and through the through hole, the pressurized steam enters the annular chamber and then enters the vertical spray pipe. Finally, it is sprayed out by the nozzles on the annular chamber and the vertical spray pipe, and sprayed onto each concrete slab for steam curing. Then, the motor is started, and the motor drives the annular chamber to rotate through the connecting sleeve. The annular chamber drives the vertical spray pipe to rotate at the same time. In this way, the concrete slab can be steam cured by rotating air jet, which makes the steam curing effect better and reduces dead zones.
[0008] Preferably, the annular box has an annular groove and a through hole, which are connected. The annular groove and through hole allow the gas supply pipe to deliver pressurized steam to the rotating annular box.
[0009] Preferably, the pressure regulating and venting mechanism includes a sleeve, a tapered tube, a plug, a sliding sleeve, a sliding column, a guide block, a spring, a connecting rod sleeve, an adjusting rod, a knob, a limiting bolt, an annular limiting groove, and vent holes. The top of the steam curing chamber is fixedly connected to the sleeve, the tapered tube is fixedly connected inside the sleeve, the plug is slidably connected inside the tapered tube, the upper end of the plug is fixedly connected to the sliding sleeve, the sliding column is slidably connected inside the sliding sleeve, a spring is provided inside the sliding sleeve, the upper end of the sliding column is fixedly connected to the connecting rod sleeve, the adjusting rod is rotatably connected inside the connecting rod sleeve, the adjusting rod is threadedly connected to the sleeve, the top of the adjusting rod is fixedly connected to the knob, the connecting rod sleeve is threadedly connected to the limiting bolt, the tail end of the limiting bolt is slidably connected to the adjusting rod, and the sleeve has multiple arrayed vent holes. When the air pressure inside the curing chamber rises, the air pressure enters the conical tube and pushes the plug inside the tube upward. The plug causes the sliding sleeve to slide on the sliding column and compresses the spring. Then the air pressure is discharged from the gap between the plug and the conical tube, and finally discharged through the exhaust hole. When the air pressure inside the curing chamber stabilizes, the plug will be pushed back by the spring and reset, resealing the conical tube. This process repeats to achieve automatic pressure relief.
[0010] Preferably, one end of the spring is fixedly connected to the sliding pin, and the other end of the spring is fixedly connected to the inner surface of the sliding sleeve. The spring allows elastic force to be applied to the plug.
[0011] Preferably, a guide block is fixedly connected to the sliding column, and the guide block is slidably connected to the sleeve. The guide block guides the relative sliding between the sliding column and the sleeve.
[0012] Preferably, the surface of the adjusting rod is provided with an annular limiting groove, which is slidably connected to the limiting bolt. The annular limiting groove ensures that the adjustment rod's rotation is not affected by the limiting bolt, and also facilitates the connection between the adjusting rod and the connecting rod sleeve.
[0013] Preferably, the material support mechanism includes a support frame, vents, locking blocks, locking posts, and support blocks. The support frame has multiple evenly distributed vents. A locking block is fixedly connected to the bottom of the support frame, and the locking block contacts the support plate. A locking post and a support block are fixedly connected to the upper end of the support frame. By placing the cut concrete slabs onto the support blocks, and to increase the number of steam-cured concrete slabs, simply insert a locking block from another support frame into the locking post of the lower support frame, and then place the concrete slabs onto the support blocks in the same way. This process can be repeated to place multiple concrete slabs simultaneously.
[0014] The process for producing autoclaved aerated concrete (AAC) panels using the aforementioned manufacturing equipment includes the following steps: Step 1: First, add sand and fly ash raw materials into the hopper, and after metering, transport them to the grinder for grinding. Then, after entering the ball mill, they enter the slurry tank and are transported by the slurry pump to the slurry tank for storage and later use. Step 2: Add the lumpy lime to the lime hopper for crushing, and then use a bucket elevator to lift the lime to the granular lime silo for storage. Step 3: The steel bars are straightened, cut, and welded using a fully automatic mesh welding machine. After welding, the steel bars need to be dried and protected against corrosion before storage. Step 4: After the metered materials are automatically proportioned and fully mixed by the casting mixer, they are lowered into the mold box by the bubble combing machine. During the slurry casting process, the bubble combing machine works to even out the air bubbles in the slurry. When producing the board, the cast mold box is transferred by the casting transfer car and sent to the insertion position by the friction wheel. The prepared wire mesh cage is inserted and then enters the curing room for curing. Step 5: Enter the curing room for curing. The green body completes the curing process through gas generation, initial setting, and hardening. When producing boards, after the green body leaves the curing room, it is removed from the mold and placed on the cutting station. The mold box after demolding is returned to continue the next round of oiling and casting. The green body is first cut on the side by the crushing blade, coarse blade, and fine blade in the side cutting machine. At the same time, the board is processed. The thickness of the board or block is precisely cut by the horizontal cutting machine. The cut green body is then cut vertically. After the cutting is completed, it is ready for steam curing. Step 6: Place a single material support mechanism in the center of the support plate, and then place the cut concrete slabs on the support block. If you need to increase the number of steam-cured concrete slabs, simply insert the clip on another support frame into the clip column of the lower support frame, and then place the concrete slabs on the support block in the same way. Repeat this process to place multiple concrete slabs at the same time. Step 7: Push the support plate, which slides along the guide rail into the steam curing chamber via a slider. Then close the chamber cover and lock it with the buckle. Step 8: Pressurized steam is delivered into the annular box through the air supply pipe. After passing through the annular groove and through the through hole, the pressurized steam enters the annular box and then enters the vertical spray pipe. Finally, it is sprayed out by the nozzles on the annular box and the vertical spray pipe and sprayed onto each concrete slab for steam curing. Then, the motor is started. The motor drives the annular box to rotate through the connecting sleeve. The annular box drives the vertical spray pipe to rotate at the same time. In this way, the concrete slab can be rotated and steam-cured by air jets, which makes the steam curing effect better and reduces dead corners. Step 9: When the air pressure in the curing chamber rises, the air pressure enters the cone tube and pushes the plug inside the cone tube upward. The plug will drive the sliding sleeve to slide on the sliding column and compress the spring. Then the air pressure will be discharged from the gap between the plug and the cone tube, and finally discharged through the exhaust hole. When the air pressure in the curing chamber stabilizes, the plug will be pushed back by the spring to reset and reseal the cone tube. This process is repeated to achieve the purpose of automatic pressure relief. Step 10: To adjust the pressure value of the pressure relief, simply rotate the adjusting rod by turning the knob. The adjusting rod will move vertically through the threaded movement between it and the sleeve. Then, the adjusting rod will drive the sliding column to move through the connecting rod sleeve. The sliding column will slide inside the sleeve and compress or release the spring, thereby adjusting the compression space of the spring and thus achieving the purpose of adjusting the pressure value of the pressure relief. It is simple and convenient. Step 11: After steam curing is complete, turn off all electrical equipment and stop the gas supply. Then open the silo cover and pull out the steam-cured concrete slab. After it cools down, it can be packaged and sold.
[0015] The beneficial effects of this invention are as follows: This invention relates to an autoclaved aerated concrete (AAC) slab manufacturing equipment and production process, which features good steam curing effect, automatic pressure relief, and simultaneous steam curing of multiple concrete slabs. In specific applications, it has the following beneficial effects: First, by setting a rotary jet mechanism at the top of the steam curing chamber, an electric motor can drive a ring box with nozzles to rotate. A vertical spray pipe with nozzles is also set at the bottom of the ring box. Then, the air supply pipe can deliver pressurized steam from the side to the ring box and the vertical spray pipe. This allows for the rotary spraying of pressurized steam onto the concrete slab, resulting in better steam curing and reduced dead zones. Secondly, by setting a pressure regulating and venting mechanism at the top of the steam curing chamber, when the air pressure inside the steam curing chamber rises, the air pressure can push up the plug, achieving automatic pressure relief and ensuring the stability of the air pressure inside the steam curing chamber. Moreover, by adjusting the pressure on the spring, the pressure required for the plug to be pushed up can be controlled, thereby achieving the effect of pressure regulation and venting. Finally, a material support mechanism is set up to hold the concrete slabs. The upper and lower ends of the support frame are respectively equipped with clamps and clamps. By cooperating the clamps and clamps on two adjacent support frames, the material support mechanism can be stacked, thereby allowing multiple concrete slabs to be steam-cured at the same time, improving the production efficiency of concrete slabs.

[0019] like Figure 1-6 As shown, the specific implementation adopts the following technical solution: Example
[0020] An autoclaved aerated concrete (AAC) panel manufacturing equipment includes a curing chamber 1, a rotary jetting mechanism 2, a pressure regulating and venting mechanism 3, a chamber cover 4, a buckle 5, a guide rail 6, a slider 7, a support plate 8, and a material support mechanism 9. The chamber cover 4 is hinged to the curing chamber 1, and the buckle 5 is hinged to the chamber cover 4 and engages with the curing chamber 1. The guide rail 6 is fixedly connected to the bottom inner side of the curing chamber 1, and the slider 7 is slidably connected inside the guide rail 6. The bottom of the slider 7 is provided with a ball bearing 10, which contacts the guide rail 6. The ball bearing 10 reduces the friction between the slider 7 and the guide rail 6. The support plate 8 is fixedly connected to the upper end of the slider 7.
[0021] The top of the steam curing chamber 1 is equipped with a rotary jet mechanism 2, which includes a motor 21, a connecting sleeve 22, an annular box 23, a vertical spray pipe 24, a nozzle 25, a fixing rod 26, a sleeve 27, an air supply pipe 28, an annular groove 29, and a through hole 210. The motor 21 is located at the top of the steam curing chamber 1, and its output shaft passes through and is rotatably connected to the steam curing chamber 1. A connecting sleeve 22 is bolted to the output shaft, and an annular box 23 is fixedly connected to the bottom of the connecting sleeve 22. A vertical spray pipe 24 is fixedly connected to the bottom of the annular box 23. Both the vertical spray pipe 24 and the annular box 23 are equipped with multiple evenly spaced nozzles. The nozzle 25 of the cloth is rotatably connected to the outside of the ring box 23, and a sleeve 27 is fixedly connected to the sleeve 27. The fixed rod 26 is fixedly connected to the inner surface of the steam curing chamber 1. An air supply pipe 28 is fixedly connected inside the sleeve 27. The air supply pipe 28 is connected into the ring box 23. The air supply pipe 28 passes through the steam curing chamber 1 and extends to the outside of the steam curing chamber 1. The other end of the air supply pipe 28 is connected to a pressurized steam source. The ring box 23 is provided with an annular groove 29 and a through hole 210. The annular groove 29 and the through hole 210 are connected. Through the setting of the annular groove 29 and the through hole 210, the air supply pipe 28 can deliver pressurized steam to the rotating ring box 23. Pressurized steam is delivered into the annular box 23 through the air supply pipe 28. After passing through the annular groove 29 and the through hole 210, the pressurized steam enters the annular box 23 and then enters the vertical spray pipe 24. Finally, it is sprayed out by the nozzles 25 on the annular box 23 and the vertical spray pipe 24 and sprayed onto each concrete slab for steam curing. Then, the motor 21 is started. The motor 21 drives the annular box 23 to rotate through the connecting sleeve 22. The annular box 23 drives the vertical spray pipe 24 to rotate at the same time. In this way, the concrete slab can be rotated and steam-cured, which makes the steam curing effect better and reduces dead corners.
[0022] The steam curing chamber 1 is equipped with a pressure regulating and venting mechanism 3 at its top. The pressure regulating and venting mechanism 3 includes a sleeve 31, a tapered tube 32, a plug 33, a sliding sleeve 34, a sliding column 35, a guide block 36, a spring 37, a connecting rod sleeve 38, an adjusting rod 39, a knob 310, a limiting bolt 311, an annular limiting groove 312, and a vent 313. The sleeve 31 is fixedly connected to the top of the steam curing chamber 1. A tapered tube 32 is fixedly connected inside the sleeve 31. A plug 33 is slidably connected inside the tapered tube 32. The upper end of the plug 33 is fixed... A sliding sleeve 34 is connected, and a sliding column 35 is slidably connected inside the sliding sleeve 34. A guide block 36 is fixedly connected to the sliding column 35. The guide block 36 is slidably connected to the sleeve 31. The guide block 36 guides the relative sliding between the sliding column 35 and the sliding sleeve 34. A spring 37 is provided inside the sliding sleeve 34. One end of the spring 37 is fixedly connected to the sliding column 35, and the other end of the spring 37 is fixedly connected to the inner surface of the sliding sleeve 34. The spring 37 can apply elastic force to the plug 33. The upper end of the sliding column 35 is fixedly connected to a connecting rod sleeve 38. An adjusting rod 39 is rotatably connected inside the connecting rod sleeve 38. The adjusting rod 39 is threadedly connected to the sleeve 31. A knob 310 is fixedly connected to the top of the adjusting rod 39. A limiting bolt 311 is threadedly connected inside the connecting rod sleeve 38. The tail end of the limiting bolt 311 is slidably connected to the adjusting rod 39. An annular limiting groove 312 is formed on the surface of the adjusting rod 39. The annular limiting groove 312 is slidably connected to the limiting bolt 311. By setting the annular limiting groove 312, the engagement of the limiting bolt 311 not only does not affect the rotation of the adjusting rod 39, but also facilitates the connection between the adjusting rod 39 and the connecting rod sleeve 38. The sleeve 31 has multiple arrayed exhaust holes 313. When the air pressure inside the steam curing chamber 1 rises, the air pressure enters the cone tube 32 and pushes the plug 33 inside the cone tube 32 upward. The plug 33 drives the sliding sleeve 34 to slide on the sliding column 35 and compresses the spring 37. Then the air pressure is discharged from the gap between the plug 33 and the cone tube 32 and finally discharged through the exhaust hole 313. When the air pressure inside the steam curing chamber 1 stabilizes, the plug 33 will be pushed back and reset by the spring 37, resealing the cone tube 32. This process is repeated to achieve the purpose of automatic pressure relief.
[0023] The support plate 8 is equipped with a material support mechanism 9, which includes a support frame 91, ventilation holes 92, locking blocks 93, locking posts 94, and support blocks 95. The support frame 91 has multiple evenly distributed ventilation holes 92. A locking block 93 is fixedly connected to the bottom of the support frame 91, and the locking block 93 contacts the support plate 8. The upper end of the support frame 91 is fixedly connected to the locking post 94 and the support block 95. By placing the cut concrete slabs on the support block 95, and to increase the number of steam-cured concrete slabs, simply insert the locking block 93 on another support frame 91 into the locking post 94 of the lower support frame 91, and then place the concrete slabs on the support block 95 in the same way. This process can be repeated to place multiple concrete slabs simultaneously.
[0024] The process for producing autoclaved aerated concrete (AAC) panels using the aforementioned manufacturing equipment includes the following steps: Step 1: First, add sand and fly ash raw materials into the hopper, and after metering, transport them to the grinder for grinding. Then, after entering the ball mill, they enter the slurry tank and are transported by the slurry pump to the slurry tank for storage and later use. Step 2: Add the lumpy lime to the lime hopper for crushing, and then use a bucket elevator to lift the lime to the granular lime silo for storage. Step 3: The steel bars are straightened, cut, and welded using a fully automatic mesh welding machine. After welding, the steel bars need to be dried and protected against corrosion before storage. Step 4: After the metered materials are automatically proportioned and fully mixed by the casting mixer, they are lowered into the mold box by the bubble combing machine. During the slurry casting process, the bubble combing machine works to even out the air bubbles in the slurry. When producing the board, the cast mold box is transferred by the casting transfer car and sent to the insertion position by the friction wheel. The prepared wire mesh cage is inserted and then enters the curing room for curing. Step 5: Enter the curing room for curing. The green body completes the curing process through gas generation, initial setting, and hardening. When producing boards, after the green body leaves the curing room, it is removed from the mold and placed on the cutting station. The mold box after demolding is returned to continue the next round of oiling and casting. The green body is first cut on the side by the crushing blade, coarse blade, and fine blade in the side cutting machine. At the same time, the board is processed. The thickness of the board or block is precisely cut by the horizontal cutting machine. The cut green body is then cut vertically. After the cutting is completed, it is ready for steam curing. Step 6: Place the single material support mechanism 9 at the center of the support plate 8, and then place the cut concrete slab on the support block 95. If you need to increase the number of steam-cured concrete slabs, simply insert the locking block 93 on another support frame 91 into the locking post 94 of the lower support frame 91, and then place the concrete slab on the support block 95 in the same way. Repeat this process to place multiple concrete slabs at the same time. Step 7: Push the support plate 8, which slides along the guide rail 6 via the slider 7 into the steam curing chamber 1. Then close the chamber cover 4 and lock it with the buckle 5. Step 8: Pressurized steam is delivered into the annular box 23 through the air supply pipe 28. After passing through the annular groove 29 and the through hole 210, the pressurized steam enters the annular box 23 and then enters the vertical spray pipe 24. Finally, it is sprayed out by the nozzles 25 on the annular box 23 and the vertical spray pipe 24 and sprayed onto each concrete slab for steam curing. Then, the motor 21 is started. The motor 21 drives the annular box 23 to rotate through the connecting sleeve 22. The annular box 23 drives the vertical spray pipe 24 to rotate at the same time. In this way, the concrete slab can be rotated and steam-cured, which makes the steam curing effect better and reduces dead corners. Step 9: When the air pressure inside the steam curing chamber 1 rises, the air pressure will enter the cone tube 32 and push the plug 33 inside the cone tube 32 upward. The plug 33 will drive the sliding sleeve 34 to slide on the sliding column 35 and compress the spring 37. Then the air pressure will be discharged from the gap between the plug 33 and the cone tube 32, and finally discharged through the exhaust hole 313. When the air pressure inside the steam curing chamber 1 stabilizes, the plug 33 will be pushed back and reset by the spring 37, resealing the cone tube 32. This process is repeated to achieve the purpose of automatic pressure relief. Step 10: To adjust the pressure value of the pressure relief, simply rotate the adjusting rod 39 by knob 310. The adjusting rod 39 will move vertically through the threaded movement between it and sleeve 31. Then, the adjusting rod 39 will drive the sliding column 35 to move through the connecting rod sleeve 38. The sliding column 35 will slide in the sliding sleeve 34 and compress or release the spring 37, thereby adjusting the compression space of the spring 37. This achieves the purpose of adjusting the pressure value of the pressure relief, which is simple and convenient. Step 11: After steam curing is complete, turn off all electrical equipment and stop the gas supply. Then open the silo cover 4 and pull out the steam-cured concrete slab. After it cools down, it can be packaged and sold.

The support frame (91) has multiple evenly distributed vents (92). The bottom of the support frame (91) is fixedly connected to the locking block (93), which contacts the support plate (8). The upper end of the support frame (91) is fixedly connected to the locking post (94) and the support block (95).
4. The process for producing autoclaved aerated concrete panels using the manufacturing equipment according to any one of claims 1-3, characterized in that: Includes the following steps: Step 1: First, add sand and fly ash raw materials into the hopper, and after metering, transport them to the grinder for grinding. Then, after entering the ball mill, they enter the slurry tank and are transported by the slurry pump to the slurry tank for storage and later use. Step 2: Add the lumpy lime to the lime hopper for crushing, and then use a bucket elevator to lift the lime to the granular lime silo for storage. Step 3: The steel bars are straightened, cut, and welded using a fully automatic mesh welding machine. After welding, the steel bars need to be dried and protected against corrosion before storage. Step 4: After the metered materials are automatically proportioned and fully mixed by the casting mixer, they are lowered into the mold box by the bubble combing machine. During the slurry casting process, the bubble combing machine works to even out the air bubbles in the slurry. When producing the board, the cast mold box is transferred by the casting transfer car and sent to the insertion position by the friction wheel. The prepared wire mesh cage is inserted and then enters the curing room for curing. Step 5: Enter the curing room for curing. The green body completes the curing process through gas generation, initial setting, and hardening. When producing boards, after the green body leaves the curing room, it is removed from the mold and placed on the cutting station. The mold box after demolding is returned to continue the next round of oiling and casting. The green body is first cut on the side by the crushing blade, coarse blade, and fine blade in the side cutting machine. At the same time, the board is processed. The thickness of the board or block is precisely cut by the horizontal cutting machine. The cut green body is then cut vertically. After the cutting is completed, it is ready for steam curing. Step 6: Place a single material support mechanism (9) in the center of the support plate (8), and then place the cut concrete slab on the support block (95). If you need to increase the number of steam-cured concrete slabs, simply insert the clip (93) on another support frame (91) into the clip (94) of the lower support frame (91), and then place the concrete slab on the support block (95) in the same way. Repeat this process to place multiple concrete slabs at the same time. Step 7: Push the support plate (8), and the support plate (8) slides into the steam curing chamber (1) on the guide rail (6) via the slider (7). Then close the chamber cover (4) and lock it with the buckle (5). Step 8: Pressurized steam is delivered into the annular box (23) through the air supply pipe (28). The pressurized steam enters the annular box (23) after passing through the annular groove (29) and the through hole (210), and then enters the vertical spray pipe (24). Finally, it is sprayed out by the nozzles (25) on the annular box (23) and the vertical spray pipe (24) and sprayed onto each concrete slab for steam curing. Then, the motor (21) is started. The motor (21) drives the annular box (23) to rotate through the connecting sleeve (22). At the same time, the annular box (23) drives the vertical spray pipe (24) to rotate. In this way, the concrete slab can be rotated and steam-cured by air jet, which makes the steam curing effect better and reduces dead corners. Step 9: When the air pressure in the steam curing chamber (1) rises, the air pressure will enter the cone tube (32) and push the plug (33) in the cone tube (32) upward. The plug (33) will drive the sliding sleeve (34) to slide on the sliding column (35) and compress the spring (37). Then the air pressure will be discharged from the gap between the plug (33) and the cone tube (32) and finally discharged through the exhaust hole (313). When the air pressure in the steam curing chamber (1) stabilizes, the plug (33) will be pushed back and reset by the spring (37) to reseal the cone tube (32). This process is repeated to achieve the purpose of automatic pressure relief. Step 10: If it is necessary to adjust the pressure value of the pressure relief, simply rotate the adjusting rod (39) by the knob (310). The adjusting rod (39) will generate a vertical displacement through the threaded movement between it and the sleeve (31). Then the adjusting rod (39) will drive the sliding column (35) to move through the connecting rod sleeve (38). The sliding column (35) will slide in the sliding sleeve (34) and squeeze or release the spring (37), thereby adjusting the compression space of the spring (37) to achieve the purpose of adjusting the pressure value of the pressure relief. It is simple and convenient. Step 11: After steam curing is complete, turn off all electrical equipment and stop the gas supply. Then open the silo cover (4) and pull out the steam-cured concrete slab. After it cools down, it can be packaged and sold.
