TECHNICAL FIELD

[0002] With the continuous development of industry, portland cement as a binder is widely used in the construction industry, and the demand for portland cement is increasing in countries around the world. According to statistics, the production of portland cement in China in 2020 reached 2.395 billion tons. Every ton of cement production emits about 810 kg of carbon dioxide (CO2), and the CO2 emitted during the production process accounts for 5% to 8% of the global CO2 emissions, ranking third in the world in terms of CO2 emissions. Therefore, the development of new types of cementing materials to replace portland cement is of great significance to the green and low-carbon development of the building materials industry. Due to the emission of a large amount of carbon dioxide during the production and use of traditional portland cement-based building materials, new low-carbon cementing materials represented by geopolymer have become a research hotspot in recent years.

[0018] Please see Figures 1-6 This invention provides an automated preparation equipment for fly ash lightweight geopolymer blocks, comprising: Multiple input conveyor belts 1 are provided. The output end of each input conveyor belt 1 is fixedly mounted on the upper end of the mixer 2, and each input conveyor belt 1 inputs different raw materials into the mixer 2 according to the corresponding input speed. The polymer conveyor belt 3 has its input end fixedly installed below the output end of the mixer 2. A polymer molding mechanism 4 is fixedly installed below the output end of the polymer conveyor belt 3. A molding die conversion mechanism 5 is horizontally embedded on the polymer molding mechanism 4. A polymer block output conveyor belt 6 is fixedly installed on one side of the molding die conversion mechanism 5. The polymer block output conveyor belt 6 is connected to a mother and daughter cart, which can send the formed blocks into the steam curing chamber for steam curing treatment, and then test the steam-cured blocks. After that, the qualified blocks are packaged and sent to the warehouse for storage. In a preferred embodiment, the number of input conveyor belts 1 and the conveying speed of each input conveyor belt 1 are adjusted according to the actual situation. The conveying speed ratio of the input conveyor belts 1 is equal to the volume ratio of the corresponding raw materials. After screening and processing, solid raw materials such as fly ash are conveyed to the mixer 2 in a certain proportion. The mixer 2 adds an appropriate amount of water through an external water pipe to fully mix and form a flowable slurry. The mixer 2 can strictly control the mixing time and speed to ensure the uniformity and stability of the slurry. The mixed slurry is conveyed to the polymer molding mechanism 4 through the polymer conveyor belt 3. The polymer molding mechanism 4 performs the block molding work. The polymer molding mechanism 4 cooperates with the molding die conversion mechanism 5 to allow the device to intermittently produce different shapes. The preparation of blocks (with the same materials and proportions) increases the practicality of the device. When changing the mold component 57, the device can be replaced without stopping its operation, further ensuring work efficiency. During the block preparation process, the molding mold conversion mechanism 5 cleans the components involved in the slurry forming to prevent material adhesion that could reduce block quality. It also dries the cleaned components to further control their humidity and prevent it from affecting the humidity of the slurry material, thus further ensuring block quality. The polymer block output conveyor belt 6 transports the formed blocks along with the support plate to an external mother-daughter cart. The mother-daughter cart sends the formed blocks into the steam curing chamber for steam curing. The steam-cured blocks are then inspected, and the qualified blocks are packaged and sent to the warehouse for storage.

[0019] Furthermore, the polymer molding mechanism 4 includes: A polymer temporary storage bin 41 is fixedly installed below the output end of the polymer conveyor belt 3, and an automatic opening and closing door is provided below the polymer temporary storage bin 41; A fixed frame 42 is set on the side of the polymer temporary storage bin 41 in the running direction. A pressure head lifter 44 is set on the upper end of the fixed frame 42. A block machine driver 45 is connected to the upper end of the pressure head lifter 44. A pressure head block 43 is fixedly set horizontally at the lower end. A mold part holder 46 is fixedly assembled at the lower end of the shrinking pressure head block 43. In a preferred embodiment, the mixed slurry is conveyed to the polymer temporary storage chamber 41 via the polymer conveyor belt 3. The polymer temporary storage chamber 41 stores the injected slurry and periodically feeds a certain amount of slurry to the polymer support component 53 running directly below it, thereby further ensuring the unit volume of the block and avoiding waste. At the same time, it avoids the block being incomplete due to insufficient slurry. When the polymer support component 53 carrying the slurry rotates with the annular rotating chain 52 to directly below the pressure head block 43, the pressure head block 43 fixes the mold component 57 and completes the block forming work with the cooperation of each component. After the forming work is completed, the pressure head block 43 drives the mold component 57 to rise under the drive of the pressure head lifter 44. While completing the separation of the mold component 57 from the block, it ensures that the mold component 57 will not affect the block and components during the clamping and rotation process.

[0020] Furthermore, the molding die conversion mechanism 5 includes: A fixed support frame 51 is horizontally fixedly embedded in the polymer molding mechanism 4. A ring rotating chain 52 is horizontally rotatably arranged on the fixed support frame 51. Multiple sets of polymer bearing components 53 are fixedly assembled on the ring rotating chain 52. The carrier plate input device 54 is provided with a plurality of carrier plates 56, and the carrier plate input device 54 is fixed to one side of the fixed support frame 51; Both the washer 58 and the dehumidifier 59 are fixedly mounted on the fixed support frame 51, and the dehumidifier 59 is close to the molding die conversion mechanism 5 in the running direction of the annular rotating chain 52. The mold component replacement assembly 55 is fixedly installed inside the fixed support frame 51; In a preferred embodiment, the carrier plate input device 54 can supplement the carrier plate 56 onto the polymer carrier assembly 53. The carrier plate 56 can cooperate with the polymer carrier assembly 53 to carry the slurry and complete the block forming process. At the same time, the carrier plate 56 can also serve as a tray for the formed blocks, thereby facilitating the transportation of the blocks and preventing damage during transportation. The cleaner 58 can wash the polymer carrier assembly 53, the carrier plate 56, and the mold component 57 to prevent them from having some slurry stuck to them during previous work or having certain stains before work, which would reduce the quality of the blocks. The dehumidifier 59 can remove excess water from the polymer carrier assembly 53, the carrier plate 56, and the mold component 57 after cleaning, while maintaining a certain humidity for the polymer carrier assembly 53, the carrier plate 56, and the mold component 57. This prevents the humidity of the components from fluctuating due to long-term use or a decrease in external temperature, which would affect the humidity of the slurry and thus the quality of the blocks and production efficiency, as is the case in traditional devices.

[0021] Furthermore, the molding die conversion mechanism 5 can be divided into four regions, A, B, C and D, according to its state. The polymer support component 53 located in region A is provided with a mold component 57, and the polymer support component 53 located in regions A, B and D is provided with a support plate 56. In a preferred embodiment, when the polymer support assembly 53 carrying the molded blocks reaches the junction of points B and C, the polymer block output conveyor belt 6 transports the molded blocks along with the support plate to an external mother-daughter cart. The mother-daughter cart sends the molded blocks into a steam curing chamber for steam curing, and then inspects the cured blocks. Qualified blocks are then packaged and stored in a warehouse. The annular rotating chain 52 continues to rotate. When the polymer support assembly 53 reaches the junction of points C and D, the support plate input device 54 inputs a support plate 56 onto the polymer support assembly 53. The annular rotating chain 52 continues to rotate. When the polymer support assembly 53 reaches the junction of points D and A, the mold replacement assembly 55 places a mold component 57 onto the polymer support assembly 53. During mold replacement, the mold component 57 placed on the polymer support assembly 53 at the junction of points D and A can be replaced manually or by machine. This process is repeated multiple times until all mold components 57 have been replaced.

[0022] Furthermore, the polymer carrier component 53 includes: A rotating fixture 531 is horizontally fixedly mounted on the annular rotating chain 52. A support fixing plate 532 is horizontally fixedly provided on the rotating fixture 531. A lifting hydraulic cylinder 533 is fixedly embedded on the rotating fixture 531 between the support fixing plate 532 and the annular rotating chain 52. A material release device 534 is horizontally fixedly mounted on the upper end of a lifting hydraulic cylinder 533, and a vibrator 535 is fixedly mounted on the material release device 534. In a preferred embodiment, the solid material release device 534 can cooperate with the bearing plate 56 to carry the slurry. At the same time, the vibrator 535 installed on it can vibrate the slurry injected into the polymer temporary storage chamber 41 to prevent the presence of cavities and air bubbles in the slurry, which would affect the molding quality of the blocks. The lifting hydraulic cylinder 533 can separate the solid material release device 534 from the molded blocks to further ensure the quality of the blocks.

[0023] Furthermore, the lifting hydraulic cylinder 533 of the polymer bearing component 53 located in area A extends along the running direction of the annular rotating chain 52. During this process, the relative height of the solid material demolding device 534 continuously rises, thereby causing the solid material demolding device 534 to separate from the block until the highest point of the lifting hydraulic cylinder 533, thus facilitating the output of the polymer block from the conveyor belt 6.

[0024] Furthermore, the mold component replacement assembly 55 includes: The first drive motor 551 is fixedly installed inside the fixed support frame 51. A rotating plate 552 is fixedly mounted on the output shaft of the first drive motor 551. Twelve fixing blocks 553 are fixedly embedded on the rotating plate 552. A second drive motor 554 is provided at the lower end of each fixing block 553. Each fixed block 553 is fixedly mounted with a fixed bracket 555 at its upper end. Each set of fixed brackets 555 is vertically rotatably provided with a rotating screw 556. The rotating screw 556 is fixedly mounted on the output shaft of the second drive motor 554, and each rotating screw 556 is horizontally provided with a mold part holder 557. In a preferred embodiment, the mold part holder 557 is used to hold the mold part 57. The setting of rotating the lead screw 556 can change the relative height of the mold part 57, thereby adapting to the clamping and placement of the mold part 57 in different states.

[0025] Furthermore, the twelve mold part holders 557 are arranged at equal intervals around their circumferences, and the mold part 57 is clamped on the mold part holders 557 located in areas B, C, and D.

[0026] An automated method for preparing fly ash lightweight geopolymer blocks includes the following steps: S1. Adjust the number of input conveyor belts 1, the conveying speed of each input conveyor belt 1, and the specific shape of the mold part 57 according to the actual situation, wherein the conveying speed ratio of the input conveyor belts 1 is equal to the volume ratio of the corresponding raw materials; S2. After screening and processing, solid raw materials such as fly ash are transported to the mixing mixer 2 in a certain proportion; S3. The mixer 2 will add an appropriate amount of water through the external water pipe and mix it thoroughly to form a flowable slurry; S4. The mixed slurry is transported to the polymer temporary storage chamber 41 via the polymer conveyor belt 3. A certain amount of slurry is periodically fed into the polymer support component 53 running directly below it from the polymer temporary storage chamber 41. S5. When the polymer bearing component 53 carrying the slurry rotates with the annular rotating chain 52 to directly below the pressure head block 43, the pressure head block 43 will fix the mold component 57 and complete the block forming work with the cooperation of each component. S6. After the block forming work is completed, the mold component replacement component 55 will clamp the completed mold component 57 and disengage from the polymer support component 53 by rotation; S7. When the polymer carrier assembly 53 carrying the molded blocks runs to the junction of B and C, the polymer block output conveyor belt 6 will transport the molded blocks along with the carrier plate to the external mother and daughter car. The mother and daughter car will send the molded blocks into the steam curing chamber for steam curing treatment, and will test the steam-cured blocks. Then, the qualified blocks will be packaged and sent to the warehouse for storage. S8. The annular rotating chain 52 continues to rotate. When the polymer carrier assembly 53 runs to the junction of C and D, the carrier plate input device 54 will input the carrier plate 56 onto the polymer carrier assembly 53. S9. The annular rotating chain 52 continues to rotate. When the polymer carrier assembly 53 runs to the junction of D and A, the mold part changing assembly 55 will place the mold part 57 on the polymer carrier assembly 53. S10. The annular rotating chain 52 continues to rotate, and after being cleaned by the washer 58 and dried by the dehumidifier 59, it arrives directly below the polymer temporary storage chamber 41 and then continues the block forming work.
