Description

Technical Field

[0001] This utility model belongs to the technical field of solid concrete bricks, and in particular relates to a curing device for solid concrete brick blanks. Background Technology

[0002] Solid concrete bricks are building blocks made primarily of cement and sand, formed through molding and curing. During production, the curing process has a decisive impact on their final strength and durability. Concrete hardening relies mainly on the cement hydration reaction for strength formation, and this reaction must continue under suitable temperature and humidity conditions. If moisture evaporates too quickly or the curing temperature deviates from the standard range, insufficient hydration within the brick can occur, leading to problems such as early cracking and reduced strength.

[0003] According to the standards for solid concrete bricks, the curing environment needs to be controlled at a temperature of 60℃±5℃ and a humidity of over 80%. Curing under these conditions for more than 12 hours can effectively improve the early strength and density of the bricks. However, most common curing devices currently available use external steam to spray the brick blanks at a constant temperature, without an automatic covering design. Before steaming, workers still need to manually cover the brick blanks with straw mats or plastic films for insulation and to prevent steam loss. This operation is labor-intensive, has high safety risks, and low efficiency. Therefore, this application proposes a curing device for solid concrete brick blanks. Utility Model Content

[0004] This application proposes a curing device for solid concrete brick blanks. By setting up a series of structures, it solves the problems of current common curing devices that mostly rely on external steam to perform constant temperature steaming of the brick blanks, without an automatic covering design. Before steaming, workers still need to manually cover the brick blanks with straw mats or plastic films to keep them warm and prevent steam loss. This operation process is labor-intensive, has high safety risks, and low efficiency of manual covering.

[0005] This application proposes a curing device for solid concrete brick blanks, including a curing chamber. Two sets of parallel tracks are laid at the bottom of the curing chamber, and a brick blank cart is set above the tracks. A screw frame is fixed at the top center of the curing chamber. A servo motor is installed on the left side inside the screw frame. A linear screw is fixedly connected to the output shaft of the servo motor. A threaded seat is screwed to the outside of the linear screw. The bottom end of the threaded seat passes through the screw frame and is fixedly connected to a connecting frame. Two sets of sliding sleeves are fixedly connected to the bottom end of the connecting frame. A clamp is fixed on one side of the sliding sleeve. The bottom end of the clamp holds a straw curtain, and the straw curtain covers the surface above the brick blank cart.

[0006] Furthermore, hooks are welded to the side of the brick-making cart near the entrance to the curing room.

[0007] Furthermore, two sets of guide rods are symmetrically arranged on both sides below the screw frame. The guide rods are fixed to the inner wall of the curing chamber, and the sliding sleeve is slidably connected to the outside of the guide rods.

[0008] Furthermore, a flow guide frame is fixed above the inner wall of the curing chamber, located between two sets of sliding sleeves, and steam nozzles are arrayed at the bottom of the flow guide frame.

[0009] Furthermore, a steam heater is installed outside the curing room, and temperature and humidity sensors are installed at fixed points on the top of the inner wall of the curing room. The output pipeline of the steam heater is connected to the input end of the steam nozzle.

[0010] Furthermore, the track is fixed to the bottom of the curing chamber, and a ramp is provided near the entrance of the curing chamber.

[0011] Furthermore, two sets of bases are fixed to the bottom of the brick blank cart, and each set of bases is equipped with a traveling wheel. The traveling wheel is embedded in the track and rolls. A drag bar is welded to the side of the bottom of the brick blank cart near the entrance of the curing room.

[0012] Furthermore, a card holder is fixed to the outer wall of the brick blank cart on the side away from the entrance of the curing chamber. A spring is fixed inside the card holder. A card slot is opened on the side of the card holder away from the brick blank cart. A card block is fixed to the inner wall of the curing chamber. The card block and the card holder form a carding connection.

[0013] As can be seen from the above technical solution, during use, after the brick blank cart is pushed into the curing chamber and positioned, the servo motor is started to drive the linear screw to rotate, which in turn drives the threaded seat to move outward along the direction of the linear screw. The thread is a standard trapezoidal thread, and its thread helix angle is less than the equivalent friction angle. This structure naturally has self-locking characteristics. Through the connecting frame, the two sets of sliding sleeves slide symmetrically under the screw frame. The clamp unfolds and covers an area larger than the straw mat on the upper surface of the brick blank cart. Then the clamp is opened, allowing the straw mat to naturally cover the top of the brick blank cart. By connecting and fixing the straw mat hook and the hook pull buckle, the straw mat can be automatically unfolded or retracted, effectively locking in the surface moisture of the brick blank, keeping it moist, promoting full hydration of cement, and ensuring the strength of the brick body. This solves the problem that most common curing devices currently use external steam to perform constant temperature steaming of the brick blank, without an automatic covering design. Before steaming, workers still need to manually cover the brick blank with straw mats or plastic films for heat preservation and to prevent steam loss. This operation process is labor-intensive, has high safety risks, and low efficiency.

[0014] Compared with the prior art, the beneficial effects of this utility model are: (1) By setting up a servo motor, linear screw, threaded seat, connecting frame, sliding sleeve, clamp and straw curtain, the straw curtain can be automatically unfolded or retracted, effectively locking the surface moisture of the brick blank, keeping it moist, promoting the full hydration of cement, ensuring the strength of the brick body, and eliminating the need for operators to climb the brick blank cart to lay the straw curtain, thus improving the covering efficiency and operational safety. (2) By setting up a flow guide, a steam heater, a steam nozzle, and a temperature and humidity sensor, the curing process of solid concrete bricks can be controlled, reducing problems such as reduced brick strength or surface cracking caused by improper temperature and humidity control. (3) The positioning structure consisting of a card block, card seat, spring and card slot, as well as a ramp and a towing device connecting bracket, facilitates positioning and docking during loading, unloading and transportation.

[0017] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0018] See Figures 1-4 .

[0019] Currently, most common curing devices use external steam to steam the brick blanks at a constant temperature, without an automatic covering design. Before steaming, workers still need to manually cover the brick blanks with straw mats 10 or plastic films for insulation and to prevent steam loss. This operation is labor-intensive, has high safety risks, and is inefficient. Therefore, this application proposes a curing device for solid concrete brick blanks, including a curing chamber 1. Two sets of parallel tracks 15 are laid at the bottom of the curing chamber 1, and a brick blank cart 12 is set above the tracks 15. A screw frame 3 is fixed at the top center of the curing chamber 1, and a servo motor is installed on the left side of the screw frame 3. 6. A linear screw 4 is fixedly connected to the output shaft of the servo motor 6. A threaded seat 5 is screwed onto the outside of the linear screw 4. The bottom end of the threaded seat 5 passes through the screw frame 3 and is fixedly connected to a connecting frame 20. Two sets of sliding sleeves 8 are fixedly connected to the bottom end of the connecting frame 20. A clip 9 is fixed to one side of the sliding sleeve 8. The bottom end of the clip 9 holds a straw curtain 10. The straw curtain 10 covers the upper surface of the brick blank cart 12. A hook 17 is welded to the side of the brick blank cart 12 near the entrance of the curing room 1. Two sets of guide rods 18 are symmetrically arranged on both sides below the screw frame 3. The guide rods 18 are fixed to the inner wall of the curing room 1. The sliding sleeves 8 are slidably sleeved on the outside of the guide rods 18. Specifically, as shown in the figure... Figure 1 and Figure 2 As shown, after the brick blank cart 12 is pushed into the curing chamber 1 and positioned, the servo motor 6 is started, which drives the linear screw 4 to rotate, thereby causing the threaded seat 5 to move outward along the direction of the linear screw 4. The thread is a standard trapezoidal thread, and its thread helix angle is less than the equivalent friction angle. This structure naturally has self-locking characteristics. Through the connecting frame 20, the two sets of sliding sleeves 8 slide symmetrically below the screw frame 3. The clip 9 unfolds and covers an area larger than the straw curtain 10 on the upper surface of the brick blank cart 12. Then, the clip 9 is opened, so that the straw curtain 10 naturally covers the top of the brick blank cart 12. By connecting and fixing the straw curtain 10 hook to the hook 17, the straw curtain 10 is automatically unfolded or retracted, effectively locking in the surface moisture of the brick blank, keeping it moist, promoting the full hydration of cement, and ensuring the strength of the brick body.

[0020] Furthermore, a flow guide frame 7 is fixed above the inner wall of the curing chamber 1, located between two sets of sliding sleeves 8. Steam nozzles 21 are arrayed at the bottom of the flow guide frame 7. A steam heater 11 is installed outside the curing chamber 1. Temperature and humidity sensors 2 are fixedly arranged at the top of the inner wall of the curing chamber 1. The output pipe of the steam heater 11 is connected to the input end of the steam nozzles 21. Specifically, as shown... Figure 1 and Figure 3 As shown, after the straw curtain 10 unfolds to cover the brick blank cart 12, the steam provided by the steam heating furnace 11 is distributed to the array of steam nozzles 21 via the guide frame 7. The steam humidifies and sprays the brick blanks, forming a high-humidity, high-temperature, and closed curing environment. In conjunction with the temperature and humidity sensor 2, the temperature and humidity changes of the curing space are monitored in real time, and the data is fed back to the external control system in a timely manner to automatically adjust the steam supply and ensure that the temperature is maintained within the standard range of 60℃±5℃ and humidity ≥80%.

[0021] Furthermore, a track 15 is fixed at the bottom of the curing room 1. A ramp 19 is provided on the track 15 near the entrance of the curing room 1. Two sets of bases 13 are fixed at the bottom of the brick blank cart 12. Each set of bases 13 is equipped with a traveling wheel 14 at the bottom. The traveling wheel 14 is embedded in the track 15 and rolls. A drag 16 is welded to the side of the bottom of the brick blank cart 12 near the entrance of the curing room 1. Specifically, a drag 16 hanger is welded to the brick blank cart 12 near the entrance. Together with the ramp 19 at the entrance, it facilitates positioning and docking during loading, unloading and transportation, and achieves a smooth transition between different ground heights.

[0022] Furthermore, a mounting bracket 23 is fixed to the outer wall of the brick blank cart 12 on the side away from the entrance of the curing chamber 1. A spring 24 is fixed inside the mounting bracket 23. A slot 25 is opened on the side of the mounting bracket 23 away from the brick blank cart 12. A locking block 22 is fixed to the inner wall of the curing chamber 1. The locking block 22 and the mounting bracket 23 form a locking connection. Specifically, as shown... Figure 1 and Figure 4 As shown, after the brick blank cart 12 is pushed into the curing chamber 1 and reaches the designated position, the card seat 23 on the side away from the entrance is automatically inserted into the corresponding card block 22 on the inner wall of the curing chamber 1 under the action of the spring 24, so as to realize the rapid and accurate positioning of the brick blank cart 12 and ensure that the positioning structure does not loosen after being engaged.

[0023] As can be seen from the above technical solution, when in use, after the brick blank cart 12 is pushed into the curing chamber 1 along the track 15, the walking wheel 14 rolls in the track 15, and the towing device 16 facilitates loading, unloading and docking of external traction equipment. After the brick blank cart 12 is pushed to the designated position, the card seat 23 on the side away from the entrance of the curing chamber 1 automatically embeds into the card block 22 fixed on the inner wall of the curing chamber 1 under the action of the internal spring 24, and completes stable engagement through the card slot 25. After positioning is completed, the servo motor 6 is started to drive the linear screw 4 to rotate, which drives the threaded seat 5 screwed to it to move along the screw direction. Then, through the connecting frame 20, the two sets of sliding sleeves 8 slide along the guide rod 18 below the screw frame 3, so that the clamp 9 gradually moves outward and unfolds the straw curtain 10 it holds. Then, by controlling the clamp 9 to release the straw curtain 10, it falls naturally to cover the surface above the brick blank cart 12. The hook on the straw curtain 10 is fastened and fixed to the hook 17 welded to the front end of the brick blank cart 12 to prevent the moisture from evaporating too quickly during the curing process. After covering is completed, a constant-temperature steam is provided by a steam heater 11 installed outside the curing chamber 1. The steam is delivered to the guide frame 7 through the output pipeline and sprayed onto the brick blank cart 12 below the straw curtain 10 by the steam nozzles 21 arranged in an array at its bottom, forming a humid and stable high-temperature environment. At the same time, the temperature and humidity sensor 2 installed at the top of the inner wall of the curing chamber 1 monitors the indoor temperature and humidity parameters in real time and feeds the data back to the external control system to realize intelligent adjustment of the steam spraying rhythm and intensity, so that the curing temperature is maintained within the process requirements of 60℃±5℃ and humidity not less than 80%, which promotes the full hydration of cement and improves the early strength of bricks. This solves the problem that most common curing devices use external steam to spray the brick blanks at a constant temperature without an automatic covering design. Before spraying, workers still need to manually cover the brick blanks with straw curtains 10 or plastic film for heat preservation and to prevent steam loss. This operation is labor-intensive, has high safety risks, and low efficiency.
