Description

Technical Field

[0001] This utility model relates to the field of concrete block casting technology, specifically to an integrated device for casting and static stopping of autoclaved aerated concrete blocks. Background Technology

[0002] The production of autoclaved aerated concrete (AAC) blocks is gradually moving towards automation and integration. Current technology has achieved segmented processing for foundation pouring and static curing. Most mainstream production lines employ a separate layout for the pouring platform and static curing chamber, requiring manual transfer of the molds after pouring, supplemented by vibration scraping or manual leveling. In recent years, some equipment has attempted to integrate pouring and static curing functions, but the synergy of core processes remains insufficient, particularly in terms of slurry distribution uniformity and precise temperature and humidity control, where there is room for improvement.

[0003] Existing concrete block pouring equipment uses a fixed volume pump to control the pouring volume, injects grout into the template through a preset flow channel, and is equipped with a liftable scraper for surface leveling. The scraper relies on mechanical limit to achieve unidirectional leveling, but the mechanism needs to be manually reset after leveling. During the static stopping phase, the curing is accelerated by a top-blown hot air device, and the hot air flow direction is not specially designed.

[0004] However, the aforementioned existing technologies exhibit significant drawbacks in practical applications. Firstly, the fixed-volume pump cannot dynamically adjust the slurry flow rate, leading to easy overflow when excessive high-flowability slurry is poured. Secondly, the scraper lacks an automatic reset function, requiring manual adjustment after each scraping operation, which severely restricts the efficiency of continuous operation. Thirdly, the hot air in the static stop chamber blows directly onto the surface of the billet, and the localized high temperature can easily cause surface cracking of the blocks. Furthermore, uneven moisture evaporation affects the internal structural strength, ultimately restricting the improvement of the billet forming qualification rate and production cycle.

[0005] Based on this, this utility model designs an integrated device for casting and static stopping of autoclaved aerated concrete blocks to solve the above problems. Utility Model Content

[0012] Furthermore, the launching and retracting mechanism includes a fixed cylinder, a micro motor, a rotating shaft, and a connecting rope.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-10 An integrated device for casting and static curing of autoclaved aerated concrete (AAC) blocks includes a workbench 1, a static curing chamber 19, and a casting template. The workbench 1 serves as the basic support platform for the entire device. The static curing chamber 19 is used to complete the curing and solidification process of the blocks. The casting template is assembled from a first template 4 and a second template 5 to form the mold cavity structure required for block forming.

A support plate 2 is slidably connected to the upper side of the workbench 1, and the support plate 2 serves as the moving carrier of the casting template.

[0033] The translation mechanism is installed between the support plate 2 and the workbench 1 to realize the position switching of the casting template between the workbench 1 and the static chamber 19. The translation mechanism includes a micro motor 16, a lead screw and a slider. A slot is provided on the upper side of the workbench 1 for guidance.

[0034] The upper side of the support plate 2 is fixedly connected to the mounting base 3 for positioning and fixing, and the pouring template is inserted into the upper side of the mounting base 3 for easy disassembly and replacement. The pouring mechanism is installed on the upper side of the workbench 1 to complete the distribution and transportation of concrete slurry. The pouring mechanism includes a distribution pipe 6, an inlet pipe 7 and an outlet pipe 8. The distribution pipe 6 is fixedly connected to the upper side of the workbench 1 as the distribution center. The inlet pipe 7 and the outlet pipe 8 are both fixedly connected to the outside of the distribution pipe 6 to form a conveying channel. The outside of the inlet pipe 7 is threaded to facilitate the connection of the feeding equipment. There are three sets of outlet pipes 8 arranged horizontally to ensure uniform pouring. The end of the outlet pipe 8 is located directly above the pouring template to achieve precise material drop. An electric valve is installed on the outside of the outlet pipe 8 to control the flow rate.

[0035] One set of second templates 5 is externally fixedly connected to a fixed base 9 as an installation base. A leveling mechanism is installed between the fixed base 9 and the second template 5 to level the concrete surface. The leveling mechanism includes a first magnetic block 10, a second magnetic block 11, a counterweight 12, a waterproof cloth 13, and a scraper 14. The first magnetic block 10 is fixedly connected to the inner bottom of the fixed base 9 to provide adsorption force. The second magnetic block 11 is adsorbed on the upper side of the first magnetic block 10 to form a separable connection. The counterweight 12 is fixedly connected to the upper side of the second magnetic block 11 to provide downward pressure. The waterproof cloth 13 is fixedly connected to the upper side of the counterweight 12 to achieve flexible transmission. The end of the waterproof cloth 13 passes through the fixed base 9 and the outside of the second template 5 and is fixedly connected to the scraper 14 to transmit force. The scraper 14 abuts against one side of the second template 5 to maintain its working posture. The scraper 14 is limited and slidably connected between the two sets of first templates 4 to ensure accurate movement trajectory.

[0036] The take-up and release mechanism is installed outside another set of second templates 5 to realize the lifting and lowering control of scraper 14. The take-up and release mechanism includes a fixed cylinder 15, a micro motor 16, a rotating shaft 17 and a connecting rope 18. The fixed cylinder 15 and the second template 5 are fixedly connected to provide support. The micro motor 16 is fixedly connected to the outside of the fixed cylinder 15 to output power. The rotating shaft 17 is fixedly connected to one side of the output shaft of the micro motor 16 to realize rotational movement. The rotating shaft 17 is rotatably connected to the inside of the fixed cylinder 15 to ensure stable operation. The connecting rope 18 is fixedly connected to the outside of the rotating shaft 17 to transmit traction force. The end of the connecting rope 18 passes through the fixed cylinder 15 and the outside of the second template 5 and is fixedly connected to one side of the scraper 14 to realize linkage control.

[0037] An opening 20 is provided on the exterior of the static chamber 19, near the support plate 2, for the pouring template to enter and exit. A ventilation opening 21 is provided on the upper side of the static chamber 19 to ensure air circulation. A drying mechanism is fixedly installed on the inner top of the static chamber 19 to complete the block curing. The drying mechanism includes a mounting cover 22, a ventilation net 23, a fixing rod 24, a fan 25, and a heating element 26. The mounting cover 22 is fixedly connected to the inner top of the static chamber 19 to form an air duct shell. A groove is provided at the bottom of the mounting cover 22 for airflow distribution, and the ventilation net 23 is fixedly connected to the groove to achieve uniform air delivery. Fixed rods 24 are fixedly connected to the inside of the mounting cover 22 to provide support. There are two sets of fixed rods 24 arranged vertically to optimize the spatial layout. Fan 25 is fixedly connected to the outside of one of the upper fixed rods 24 to generate airflow. Heating element 26 is fixedly connected to the outside of one of the lower fixed rods 24 to provide heat. Two sets of air guide plates 27 are fixedly connected to the inside of the static chamber 19 to guide the airflow. The two sets of air guide plates 27 are installed at an angle downward to avoid direct blowing on the blank. Temperature sensor 28 is fixedly connected to the inside of the static chamber 19 to monitor the ambient temperature in real time.

[0038] In this embodiment, during the pouring stage, the concrete slurry is fed into the distribution pipe 6 through the feed pipe 7 and then evenly injected into the pouring template composed of the first template 4 and the second template 5 through three sets of discharge pipes 8. After the pouring is completed, the leveling mechanism is immediately activated. The micro motor 16 drives the rotating shaft 17 to wind the connecting rope 18, causing the scraper 14 to be pulled out to level the concrete surface. When the scraper 14 slides, the attraction between the first magnetic block 10 and the second magnetic block 11 and the gravity of the counterweight 12 are transmitted to the scraper 14 through the waterproof cloth 13. This allows the micro motor 16 to automatically reset the scraper 14 when it reverses, thus realizing the cyclic sliding of the scraper 14 and quickly leveling the concrete surface inside the template.

[0039] After leveling, the drive motor drives the lead screw to rotate, which moves the slider at the bottom of the support plate 2 along the slot of the worktable 1. The entire casting template on the mounting base 3 is pushed into the static curing position through the opening 20 of the static curing chamber 19. The drying system then starts, and the fan 25 draws in air through the vent 21. After being heated by the heating element 26, the hot air is evenly diffused through the ventilation net 23 at the bottom of the mounting cover 22. Crucially, two sets of downward-sloping air guide plates 27 direct the heat flow to the side of the block instead of blowing it directly onto the surface. This airflow design avoids cracking of the block surface caused by direct high-temperature airflow and accelerates the evaporation of internal moisture through hot air circulation. The temperature sensor 28 monitors the chamber temperature in real time and maintains the optimal static curing environment by adjusting the fan 25 and the heating element 26, promoting rapid shaping of the green body. Finally, the entire process from casting, leveling to static curing is integrated and automated, which greatly improves the efficiency and quality stability of the block forming.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
