Technical Field

[0001] The present invention relates to the field of construction technology, and particularly to a concrete steam curing device and method. Background Art

[0002] In construction projects, concrete is an extremely important and widely used building material. However, after concrete is poured, it needs to undergo a certain curing process to achieve the designed strength and durability. Traditional curing methods often rely on the temperature and humidity of the natural environment, which results in a long curing cycle and unstable effects. Especially in cold or dry regions, the curing of concrete is more difficult. To improve this problem, people have started to adopt steam curing technology, by introducing steam into the curing space to increase the environmental temperature and humidity, thereby accelerating the hardening process of concrete and improving its early strength.

[0003] Existing equipment has the following disadvantages: Although the existing concrete steam curing devices can achieve the purpose of steam curing to a certain extent, there are still some problems. For example, the steam distribution is uneven, resulting in inconsistent curing effects; the water collection system is imperfect, and the condensed water in the steam cannot be effectively collected and reused, causing waste of resources.

[0004] Therefore, the present application now proposes a concrete steam curing device and method to solve the above problems. Summary of the Invention

[0011] The temperature detection device is electrically connected to the steam generator through a plc control element.

[0012] Among them, the steam generator is communicated with the shunt pipe through a connecting pipe, and the water collecting tank is communicated with the steam generator through a water guiding pipe.

[0013] Among them, a bracket for supporting the curing box is arranged on one side of the water collecting tank away from the concrete wall, a water guiding plate is arranged at the lower end of the curing box, and the water guiding plate is inclined towards the water collecting tank.

[0014] Among them, the water level control device includes a mounting rack arranged inside the water collecting tank, a floating member arranged on the mounting rack for monitoring the water level inside the water collecting tank, a limiting member arranged on the mounting rack for restricting the mounting position of the floating member, a sealing box arranged inside the water collecting tank, and a water separating plate adjustably arranged inside the sealing box for sealing the water guiding pipe. A traction rope is arranged between the limiting member and the water separating plate, and a control member for adjusting the mounting position of the water separating plate is arranged on the sealing box.

[0015] Among them, the floating member includes a rotating shaft arranged on the mounting rack, a rotating rod sleeved on the rotating shaft, and a first floating ball arranged on the side of the rotating rod away from the rotating shaft. The first floating ball is adjustably arranged inside the water collecting tank.

[0016] Among them, the limiting member includes a connecting plate arranged on the mounting rack, a mounting frame arranged on the side of the connecting plate away from the rotating shaft, a cam fixed on the rotating shaft, a limiting rod penetrating through the mounting frame, an abutting block arranged on the side of the limiting rod close to the cam, and a connecting block fixed on the other side of the limiting rod. The traction rope is fixed on the connecting block. An elastic member is sleeved on the part of the limiting rod between the abutting block and the mounting frame, and a guide wheel for guiding the traction rope is arranged at the corresponding position of the water collecting tank for the traction rope.

[0017] Among them, the control member includes a support block fixed on the sealing box, a connecting rod sleeved on the support block, a second floating ball arranged on the side of the connecting rod away from the support block, a control button arranged at the lower end of the water collecting tank and below the second floating ball, and a power member arranged at the upper end of the sealing box. The control button is electrically connected to the power member, and the power output end of the power member penetrates through the upper end of the sealing box.

[0018] Among them, a filter screen is arranged on the sealing box.

[0020] A method for steam curing of concrete, used for operating the above-mentioned concrete steam curing device, includes the following steps:

[0021] S1. Pour the concrete wall, and install a temperature sensor in the middle of the steel reinforcement frame before pouring. After the concrete wall solidifies and forms, remove the formwork on the concrete wall and install a temperature sensor on the surface of the concrete wall;

[0022] S2. Set up a curing box according to the size of the concrete wall. The curing box is built by a frame and acrylic plates. After the curing box is built, the support brackets support the outer ends of the curing box to complete the fixing work of the curing box;

[0024] S4. Under the action of gravity, the water vapor falls into the inside of the water collection tank. When the water in the water collection tank collects to the set value, the water separation plate opens the water guide pipe, and then pumps the water in the water collection tank into the inside of the steam generator for reuse. When the water level in the water collection tank drops to the set value, the control part pushes the water separation plate downward to seal the water guide pipe and turn off the water pump.

[0026] Through the interval setting of the shunt pipe and the nozzles, the present invention realizes the uniform distribution of steam in the curing box, ensures the same curing effect for each part of the concrete, improves the curing quality. The setting of the water collection tank effectively collects the condensed water in the steam, and the water level control device can automatically control the discharge and reuse of the water according to the water level in the water collection tank, which not only avoids the waste of water resources but also reduces the curing cost. The combination of the temperature detection device and the plc control element realizes the real-time monitoring and precise control of the temperature in the curing box. According to the change of the temperature inside the concrete, the steam generator can automatically adjust the steam output to ensure that the curing temperature is always maintained within the optimal range, improving the curing efficiency. The curing box is built by a frame and acrylic plates, which not only ensures the structural stability but also facilitates observation and operation. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to Figures 1-10 , the present invention provides a technical solution: a concrete steam curing device, including a curing box 2 arranged on one side of a concrete wall 1 and a temperature detection device arranged inside the curing box 2 and on the concrete wall 1, further including:

[0040] A shunt pipe 32, arranged at intervals inside the curing box 2 and connected to a steam generator 3;

[0041] Nozzles 33, arranged at intervals inside the shunt pipe 32;

[0042] A water collecting tank 23, arranged at one side of the lower end of the curing box 2 for collecting the condensed water in the steam;

[0043] A water level control device 4, arranged inside the water collecting tank 23 for discharging the water in the water collecting tank 23;

[0044] The temperature detection device is electrically connected to the steam generator 3 through a plc control element.

[0045] It should be noted that during operation, the frame of the curing box 2 is made of galvanized angle steel and acrylic plates, and its size is set according to the size of the concrete wall 1. It can completely wrap the concrete wall 1 and support and fix the insulation box 2 to the concrete wall 1. Then, high-temperature liquid is added into the inside of the shunt pipe 32 through the steam generator 3, and the liquid is sprayed out in a mist form from the nozzle 33. The high-temperature steam raises the temperature inside the curing box 2, and the temperature detection device monitors the temperature inside the curing box 2 in real time. Then, the temperature change situation is transmitted to the plc control element, and the plc control element analyzes the data. Then, according to the temperature change situation, it controls the steam generator 3 to raise or lower the temperature inside the curing box 2. By setting this device, the temperature during the concrete curing process can be detected in real time, and the temperature inside and outside the concrete wall 1 can be controlled within an appropriate range. Through the "temperature joint control curing mechanism" such as the concrete center temperature, surface temperature, ambient temperature, curing temperature, and cooling temperature, when the temperature inside the concrete core is 50 °C, the temperature of the external curing shed should be controlled at about 40 °C, not lower than 35 °C. The temperature inside the curing box 2 should be able to follow the change of the core temperature, and always keep the temperature and humidity inside the shed in an ideal state, that is, the temperature difference between the inside and outside of the concrete wall 1 does not exceed 15 °C. Through the interval setting of the shunt pipe 32 and the nozzle 33, the uniform distribution of steam inside the curing box 2 is realized, ensuring the same curing effect on each part of the concrete and improving the curing quality. The setting of the water collection tank 23 effectively collects the condensed water in the steam, and the water level control device 4 can automatically control the discharge and reuse of water according to the water level in the water collection tank 23, avoiding the waste of water resources and reducing the curing cost. The combination of the temperature detection device and the plc control element realizes the real-time monitoring and precise control of the temperature inside the curing box. According to the change of the temperature inside the concrete, the steam generator 3 can automatically adjust the steam output to ensure that the curing temperature is always maintained within the best range, improving the curing efficiency. The curing box 2 is built with a frame and acrylic plates, ensuring both the structural stability and the convenience of observation and operation.

[0046] In one embodiment, the steam generator 3 is connected to the shunt pipe 32 through a connecting pipe 31, and the water collection tank 23 is connected to the steam generator 3 through a water guide pipe 34.

[0047] With this design, referring to Figure 4 and Figure 5 , the water collection tank 23 supplies water to the steam generator 3 through the water guide pipe 34, which can reuse the water that falls into the inside of the curing box 2, reduce the waste of water sources, and improve the utilization rate of water resources.

[0048] In one embodiment, a bracket 21 for supporting the curing box 2 is provided on the side of the water collection tank 23 away from the concrete wall 1, and a water guide plate 22 is provided at the lower end of the curing box 2. The water guide plate 22 is inclined towards the side of the water collection tank 23.

[0049] With such a design, referring to Figures 1-5 , the bracket 21 provides a stable support for the curing box 2, ensuring the stability of the curing box 2 during placement and use, preventing tilting or collapse caused by external forces or its own weight. The water guide plate 22 is inclined towards the water collection tank 23, causing the accumulated water generated inside the curing box 2 to flow into the water collection tank 23, thereby improving the drainage efficiency, facilitating the collection of water, and increasing the utilization rate of water resources.

[0050] In one embodiment, the water level control device 4 includes a mounting frame 41 disposed inside the water collection tank 23, a floating member 42 disposed on the mounting frame 41 for monitoring the water level inside the water collection tank 23, a limiting member 43 disposed on the mounting frame 41 for restricting the mounting position of the floating member 42, a sealing box 45 disposed inside the water collection tank 23, and a water blocking plate 46 adjustably disposed inside the sealing box 45 for sealing the water guide pipe 34. A traction rope 44 is disposed between the limiting member 43 and the water blocking plate 46, and a control member 47 for adjusting the mounting position of the water blocking plate 46 is disposed on the sealing box 45.

[0051] With such a design, referring to Figure 6 and Figure 10 , the floating member 42 floats up and down as the water level in the water collection tank 23 changes, and is connected to the water blocking plate 46 through the traction rope 44 to realize the automatic linkage between the water level change and the movement of the water blocking plate 46 without manual intervention. When the water level inside the water collection tank 23 rises to the set water level, the floating member 42 drives the limiting member 43 to move, and the limiting member 43 drives the water blocking plate 46 to move upward through the traction rope 44 to open the water guide pipe 34. The water in the water collection tank 23 is discharged into the steam generator 3 through the water guide pipe 34 for use. When the water level inside the water collection tank 23 drops to the set value, the control member 47 drives the water blocking plate 46 to move downward, so that the water blocking plate 46 seals the water guide pipe 34, enabling the water to be collected in the water collection tank 23. Since the amount of water vapor condensed into water is small and the formation of water is insufficient, if the water guide pipe 34 is always open to supply water to the steam generator 3, it will not only cause waste of energy but also damage the water pump.

[0052] In one embodiment, the floating member 42 includes a rotating shaft 421 disposed on the mounting frame 41, a rotating rod 422 sleeved on the rotating shaft 421, and a first floating ball 423 disposed on the side of the rotating rod 422 away from the rotating shaft 421. The first floating ball 423 is adjustably disposed inside the water collection tank 23.

[0053] With such a design, referring to Figure 7, the first floating ball 423 is in direct contact with water, capable of quickly responding to the change in the water level in the water collection tank 23, ensuring the real-time and accuracy of water level control. It is fixedly connected to the rotating shaft 421 through the rotating rod 422. When the first floating ball 423 rotates under the buoyancy force, it will drive the rotating shaft 421 to rotate on the mounting frame 41, and then drive the limiting member 43 to move, providing power for the limiting member 43 to drive the water separation plate 46 to move upward.

[0054] In one embodiment, the limiting member 43 includes a connecting plate 411 provided on the mounting frame 41, a mounting frame 432 provided on the side of the connecting plate 411 away from the rotating shaft 421, a cam 431 fixed on the rotating shaft 421, a limiting rod 433 passing through the mounting frame 432, an abutting block 434 provided on the side of the limiting rod 433 close to the cam 431, and a connecting block 436 fixed on the other side of the limiting rod 433. The towing rope 44 is fixed on the connecting block 436. An elastic member 435 is sleeved on the portion of the limiting rod 433 between the abutting block 434 and the mounting frame 432. A guide wheel 441 for guiding the towing rope 44 is provided at the corresponding position of the towing rope 44 on the water collection tank 23. The elastic member 435 is made of a spring or elastic pad with damping.

[0055] With such a design, referring to Figure 9 , the cam 431 rotates with the rotating shaft 421, and the cam 431 abuts against the abutting block 434. When the first floating ball 423 moves up to the set position, the cam 431 releases the restriction on the abutting block 434. The elastic member 435 drives the abutting block 434 to move toward the side close to the rotating shaft 421 above the cam 431. Since the cam 431 is fixed on the rotating shaft 421, the abutting block 434 can restrict the cam 431, and then fix the position of the first floating ball 423, so that the position of the water separation plate 46 is fixed, which can facilitate the discharge of water in the water collection tank 23. Since the water formed by the steam continuously flows into the interior of the water collection tank 23, if the limiting member 43 is not provided, the first floating ball 423 will continuously swing when it moves down to the lowest point, and then the water guide pipe 34 cannot be completely closed, which will cause the water pump to continuously pump the water in the water collection tank 23, resulting in the above problems of energy waste and damage to the water pump.

[0056] In one embodiment, the control member 47 includes a support block 471 fixed on the sealing box 45, a connecting rod 472 sleeved on the support block 471, a second floating ball 473 provided on the side of the connecting rod 472 away from the support block 471, a control button 474 provided at the lower end of the water collection tank 23 and below the second floating ball 473, and a power member 48 provided at the upper end of the sealing box 45. The control button 474 is electrically connected to the power member 48, and the power output end of the power member 48 passes through the upper end of the sealing box 45.

[0057] With such a design, referring toFigures 7-8 and Figure 10 As the water level in the water collecting tank 23 changes, the second floating ball 473 moves. When the water level drops to the set value, the second floating ball 473 triggers the control button 474, and the power component 48 is automatically started. The water blocking plate 46 is adjusted to move downward through its power output end, so that the water blocking plate 46 seals the water guide pipe 34, realizing the automatic control of the water level.

[0058] In one embodiment, a filter screen 341 is provided on the sealing box 45.

[0059] With this design, referring to Figure 7 and Figure 8 the filter screen 341 can effectively intercept and filter impurities, particulate matters, suspended matters, etc. in the water entering the sealing box 45, ensuring that the water quality entering the steam generator 2 is relatively clean.

[0060] In one embodiment, the water blocking plate 46 is slidably arranged on the sealing box 45. A limiting block 461 is arranged on one side of the water blocking plate 46 connected to the sealing box 45, and a limiting groove 4501 for the limiting block 461 to move is formed on the sealing box 45.

[0061] With this design, referring to Figure 8 the close fit between the limiting block 461 and the limiting groove 4501 ensures the precise positioning of the water blocking plate 46 during the sliding process, avoiding inaccurate water level control or system failure caused by position deviation.

[0062] A concrete steam curing method for operating the above-mentioned concrete steam curing device includes the following steps:

[0063] S1. Pour the concrete wall 1, and install a temperature sensor in the middle of the steel bar frame before pouring. Then, after the concrete wall 1 solidifies and forms, remove the formwork on the concrete wall 1 and install a temperature sensor on the surface of the concrete wall 1;

[0064] S2. Set up the curing box 2 according to the size of the concrete wall 1. The curing box 2 is built by a frame and an acrylic board. After the curing box 2 is built, the support 21 supports the outer end of the curing box 2 to complete the fixing work of the curing box 2;

[0065] S3. Set up the shunt pipe 32 inside the curing box 2, and then arrange the nozzles 33 at intervals on the shunt pipe 32. Install temperature sensors inside the curing box 2, and electrically connect multiple temperature sensors to the steam generator 3 through a plc control element. The temperature sensors can monitor the temperatures inside the concrete wall 1, on the surface of the concrete wall 1, and inside the curing box 2 in real time, and control the steam generator 3 to adjust the temperature inside the curing box 2 according to the change of the temperature inside the concrete wall 1 through the plc control element;

[0066] S4. Under the action of gravity, the water vapor falls into the interior of the water collection tank 23. When the water in the water collection tank 23 is collected to the set value, the water separation plate 46 opens the water guide pipe 34, and then the water in the water collection tank 23 is pumped into the interior of the steam generator 3 for reuse. When the water level in the water collection tank 23 drops to the set value, the control member 47 pushes the water separation plate 46 downward to seal the water guide pipe 34 and the water pump is turned off.

[0067] In addition, if there are descriptions involving "first", "second", etc. in the embodiments, such descriptions of "first", "second", etc. are for descriptive purposes only and should not be construed as indicating or implying their relative importance to the specification or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first", "second" may explicitly or implicitly include at least one such feature.

When the water level in the water collection tank (23) drops to the set value, the control part (47) pushes the water separation plate (46) downward to seal the water guide pipe (34), and the water pump is turned off.
