Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering, specifically, it relates to a steam generation and circulation device for concrete curing. Background Technology

[0002] A steam generator and circulation device for concrete curing is a specialized equipment system used to accelerate concrete hardening and improve early strength. It optimizes the hydration reaction through steam heating and humidity control, while simultaneously achieving energy recycling.

[0003] The prior art discloses a thermal circulation system for concrete curing (CN202122580303.3), which relates to the field of concrete curing technology. The system includes a housing and a motor. A partition is located in the middle of the housing. Heating plates are located on the inner side wall and bottom of the housing below the partition. A filter plate, an air guide pipe, and a heating element are located above the partition. Air surrounding the device is drawn into the device by a first fan, heated, and then discharged, accelerating the drying of the concrete around the device. The heating plate below the partition heats water, turning it into steam. This steam, driven by a rotating gear disc, rotates the L-shaped air guide pipe, wetting the concrete surface in the surrounding environment and preventing cracking during the drying process.

[0004] Existing technology uses a second fan to directly exhaust hot air, and the steam cures the concrete. After the steam is sprayed onto the concrete, most of the steam rises and dissipates, while a small amount cures the concrete. The heating plate heats water to generate steam, but the water source is constantly consumed and needs to be added continuously. The rising steam cannot be reused.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

The following embodiments are used to illustrate this utility model.

[0019] A steam generation and circulation device for concrete curing, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a steam guiding structure is located below the steam box 2. Below the steam box 2 is a circulation hood 5 that traps excess steam and guides water flow. A steam nozzle 16 is located in the center of the circulation hood 5. A rotating pipe 13 is fixed to the top surface of the nozzle 16 to drive the circulation hood 5 to sway and rotate the nozzle 16. The steam guiding structure also includes a frame 6, blocks 17, and springs 18. Each side of the top of the circulation hood 5 is fixedly connected to a block 17. A spring 18 is fixed to one side of each block 17. The other ends of the springs 18 are fixedly connected to both sides of the inner wall of the frame 6. Each spring 18 has a guide rod inside. The bottom surface of the frame 6 is fixedly connected to the bottom surface of the steam box 2. The steam guiding structure also includes a motor 1. 0. Connecting pipe 11, first bevel gear 14 and second bevel gear 15, the top surface of the circulation cover 5 is provided with a through groove, the rotating pipe 13 extends into the through groove, the top end of the rotating pipe 13 is rotatably connected to one end of the connecting pipe 11, the other end of the connecting pipe 11 is fixedly connected to the top surface of the inner wall of the frame 6, the first bevel gear 14 is set on the wall of the rotating pipe 13 and fixedly connected to the rotating pipe 13, the first bevel gear 14 meshes with the second bevel gear 15, the motor 10 is fixedly set on the top surface of the inner wall of the frame 6, the rotating shaft of the motor 10 is fixedly connected to one side of the second bevel gear 15, the water vapor guiding structure also includes a hose 12, the air outlet of the second fan 4 is fixedly connected to one end of the hose 12 and connected, the other end of the hose 12 is fixedly connected to the wall of the connecting pipe 11 and connected.

[0020] Turn on the power to the second blower 4 to deliver the steam inside the steam box 2 to the hose 12. Turn on the power to the motor 10. The motor 10 drives the second bevel gear 15 to rotate, and the first bevel gear 14 rotates accordingly. The rotating pipe 13 drives the nozzle 16 to rotate and spray air. The nozzle 16 sprays air downwards and sprays the gas towards the concrete. The gas then disperses upwards and is covered by the circulation hood 5. When the gas rushes towards the circulation hood 5, it is blocked by the circulation hood 5 and blows downwards towards the concrete again. The steam can be blown onto the concrete multiple times, which is recycled and accelerates the curing speed of the concrete.

[0021] A steam generation and circulation device for concrete curing, such as Figure 1 and Figure 5 As shown, the water-conducting structure also includes a water-conducting box 8, a water tank 9, a first transmission block 19, and a second transmission block 20. A first transmission block 19 is fixed to the wall of the rotating pipe 13, and a second transmission block 20 is fixed to the inner wall of the circulation shroud 5. The first transmission block 19 and the second transmission block 20 abut against each other. A water-conducting box 8 is fixed to the bottom surface of the circulation shroud 5, and a water tank 9 is opened on the top surface of the water-conducting box 8. A water pump 25 is fixed to one side of the second fan 4. The outlet pipe of the water pump 25 is fixedly connected to the inlet pipe 7 and they are connected. The inlet pipe of the water pump 25 is fixedly connected to one end of the pumping pipe 23 and they are connected. The pumping pipe 23 extends into the water tank 9 and is connected to the water tank 9. A water valve 22 is provided on the wall of the inlet pipe 7.

[0022] Steam is blown towards the circulation hood 5, which is shaped like an inverted cone. Due to the low temperature of the circulation hood 5, some of the steam blown towards it will condense into water droplets. The rotating pipe 13 drives the first transmission block 19 to rotate. When it rotates to the second transmission block 20, it abuts against the second transmission block 20, causing the end of the circulation hood 5 to sway within the frame 6. The water droplets condensed on the wall of the circulation hood 5 are vibrated and flow into the water tank 9 along the wall of the circulation hood 5. When a certain water level is reached, the power to the water pump 25 is turned on. The water pump 25 delivers water to the inlet pipe 7 through the pump pipe 23, and finally enters the steam box 2. The steam continuously increases the water volume, thus achieving recycling.

[0023] A steam generation and circulation device for concrete curing, such as Figure 1 and Figure 6 As shown, a support frame 1 is installed above the ground. A steam box 2 for generating steam is installed above the support frame 1. A first fan 3 and a second fan 4 are fixed on both sides of the steam box 2. The air outlet of the first fan 3 is connected to the steam box 2, and the air inlet of the second fan 4 is connected to the steam box 2. A support plate 27 is fixed on the inner wall of the steam box 2. A filter plate 26 is fixed on the top surface of the support plate 27 near the first fan 3, and a heating element 28 is fixed on the top surface of the support plate 27 near the second fan 4. A heating plate 24 is fixed on the bottom surface of the two support plates 27 and on the wall of the steam box 2. A water inlet pipe 7 is fixed on one side of the steam box 2. One end of the water inlet pipe 7 passes through the steam box 2 and the heating plate 24 and extends into the interior of the steam box 2.

[0024] Turn on the power to the first fan 3, the second fan 4, and the heating plate 24. The first fan 3 delivers outside air to the steam box 2, where it is filtered by the filter plate 26. The heating plate 24 heats the water, and the steam rises and mixes with the outside air. The mixture is then heated by the heating element 28 and delivered to the hose 12 by the second fan 4.

[0025] The working principle of this utility model is as follows: When the power is turned on to the first fan 3, the second fan 4, and the heating plate 24, the first fan 3 delivers outside air to the steam box 2, where it is filtered by the filter plate 26. The heating plate 24 heats the water, causing the steam to rise and mix with the outside air. The mixture then passes through the heating element 28 for further heating and is delivered to the hose 12 by the second fan 4. Turning on the power to the second fan 4 delivers the steam from inside the steam box 2 to the hose 12. Turning on the power to the motor 10 drives the second bevel gear 15 to rotate, causing the first bevel gear 14 to rotate as well. The rotating pipe 13 drives the nozzle 16 to rotate and spray air downwards. The gas is sprayed onto the concrete and then disperses upwards. The circulation hood 5 covers the gas, ensuring that the gas is contained within the circulation hood 5 when it reaches it. The steam is blown downwards onto the concrete again, and the steam can be blown onto the concrete multiple times, thus accelerating the curing speed of the concrete. The steam blows onto the circulation hood 5, which is shaped like an inverted cone. Because the temperature of the circulation hood 5 is low, some of the steam blown onto the circulation hood 5 will condense into water droplets. The rotating pipe 13 drives the first transmission block 19 to rotate. When it rotates to the second transmission block 20, it abuts against the second transmission block 20, causing the end of the circulation hood 5 to sway within the square frame 6. The water droplets condensed on the wall of the circulation hood 5 are vibrated and flow into the water tank 9 along the wall of the circulation hood 5. When a certain water level is reached, the power to the water pump 25 is turned on. The water pump 25 delivers water to the inlet pipe 7 through the pump pipe 23 and finally enters the steam box 2. The steam continuously increases the water volume, thus achieving recycling.
