Abstract
Description
Technical Field
[0001] This application belongs to the technical field of precast concrete curing equipment, specifically a temperature-controlled curing box for precast concrete with adjustable temperature and humidity. Background Technology
[0002] Concrete curing involves artificially creating specific humidity and temperature conditions to allow freshly poured concrete to harden normally or accelerate its strength development. Precast concrete curing boxes typically consist of an outer casing and an inner casing. The outer casing is generally made of high-quality cold-rolled steel plate, while the inner casing is made of stainless steel plate, providing excellent corrosion resistance. The box is equipped with shelves for placing precast components and a water tank at the bottom for heating and auxiliary humidification. It also includes heating elements, a refrigeration system, an ultrasonic humidifier, and temperature and humidity sensors.
[0003] However, the following problems still exist: the existing curing box is equipped with multiple nozzles, which are fixedly installed inside the curing box. The spray range of the fixed nozzles is static. If the size or placement of the precast parts is offset or changed, it can easily lead to insufficient steam coverage in local areas. Utility Model Content
[0004] The purpose of this application is to provide a temperature-controlled curing box for precast concrete that can adjust temperature and humidity, in order to solve the problem that existing curing boxes have multiple nozzles that are fixedly installed inside the curing box, and the spray range of the fixed nozzles is static. If the size or placement of the precast component changes, it can easily lead to insufficient steam coverage in some areas.
[0005] The technical solution adopted in this application is as follows: A temperature and humidity adjustable precast concrete temperature control curing box includes a support ring plate, a curing box is fixedly connected to the upper surface of the support ring plate, a support block is fixedly connected to the side of the curing box, a servo motor is fixedly connected to the upper surface of the support block, a threaded rod is fixedly connected to the output end of the servo motor, an internal threaded cylinder is threadedly connected to the surface of the threaded rod, a movable plate is fixedly sleeved on the surface of the internal threaded cylinder, the side of the movable plate near the inner wall of the curing box is slidably connected to the inner wall of the curing box, a first annular tube is fixedly connected to the upper surface of the movable plate, a through pipe is fixedly connected to the back of the first annular tube, a second annular tube is fixedly connected to the end of the through pipe away from the first annular tube, and nozzles are fixedly connected to the inner annular surfaces of both the first and second annular tubes.
[0006] Preferably, a steam generator is fixedly connected to the back of the curing box, and a connecting pipe is fixedly connected to the upper surface of the steam generator. The end of the connecting pipe away from the steam generator passes through the side of the support ring plate and is fixedly connected to a corrugated pipe. The end of the corrugated pipe away from the connecting pipe passes through the support ring plate and the lower surface of the curing box respectively and is fixedly sealed to the end of the first annular pipe. An air valve is fixedly sleeved on the surface of the connecting pipe. Then, when the steam generator is turned on, the steam generator runs and vaporizes the water, which then enters the first annular pipe through the connecting pipe and the corrugated pipe. Then, the water enters the second annular pipe through the connecting pipe from the first annular pipe and is then sprayed out by nozzles on the first and second annular pipes respectively.
[0007] Preferably, a temperature sensor is fixedly connected to the inner wall of the curing box, and an inner groove is formed on the upper surface of the curing box. A heating wire is fixedly connected to the inner wall of the inner groove. If the temperature inside the curing box is too low, it will slow down the hydration reaction of cement, resulting in a longer curing cycle. If the temperature inside the curing box is too high, the cement hydration reaction will be too fast, and the water will evaporate quickly, resulting in reduced strength and a loose structure. When the temperature sensor detects that the temperature inside the curing box is low, the heating wire is turned on by an external controller. The heating wire heats up and raises the temperature inside the curing box. When the temperature inside the curing box is detected to be too high, the heating wire is turned off, and the water mist vaporized by the steam generator cools the curing box.
[0008] Preferably, a support frame is fixedly connected to the side of the support ring plate, a horizontal rail is fixedly connected to the upper surface of the support frame, a rotating wheel is rotatably connected to the inner wall of the horizontal rail, a transport plate is provided on the upper surface of the rotating wheel, a precast concrete component is provided on the upper surface of the transport plate, the transport plate is connected to an external traction device, when the external traction device is running, it pulls the transport plate, the transport plate is pulled and moved by the rotating wheel, the movement of the rotating wheel then drives the precast concrete component to move into the curing box for curing.
[0009] Preferably, a rubber strip is fixedly connected to the top wall of the inner wall of the curing box. By setting the rubber strip, the two sides of the curing box can be sealed when the precast concrete component is not in the curing box, preventing the vaporized water mist from escaping from the two sides of the curing box. When the precast concrete component moves into the curing box, the precast concrete component pushes the rubber strip open and enters the curing box. Afterwards, the rubber strip returns to vertical position due to gravity to seal the curing box, reducing the occurrence of a large amount of vaporized water mist escaping from the inside of the curing box during the transportation of the precast concrete component.
[0010] Preferably, the number of nozzles is six, with three nozzles forming a group. The two groups of nozzles are respectively set on the inner ring surfaces of the first annular tube and the second annular tube. By setting the number of nozzles to six, the water mist can quickly fill the entire curing box, and at the same time, the water mist can be evenly sprayed on the surface of the precast concrete component.
[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:
[0012] 1. In this application, the steam generator is then turned on, and the steam generator operates, vaporizing the water and allowing it to enter the first annular pipe through the connecting pipe and the corrugated pipe. The water then enters the second annular pipe through the connecting pipe, and is sprayed out from the nozzles on the first and second annular pipes respectively. Then, the servo motor is turned on, driving the threaded rod to rotate. The rotation of the threaded rod drives the moving plate through the internal threaded cylinder. The movement of the moving plate drives the second and first annular pipes to move respectively. When the second annular pipe moves to the far left, the servo motor again drives the moving plate through the internal threaded cylinder. The movement of the moving plate then drives the second and first annular pipes to move in opposite directions, spraying the water into each area of the curing chamber, thus solving the problem of uneven steam distribution to a certain extent.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0021] Example:
[0022] Reference Figure 1-4 A temperature and humidity adjustable precast concrete temperature control curing box includes a support ring plate 1, a curing box 2 fixedly connected to the upper surface of the support ring plate 1, a support block 18 fixedly connected to the side of the curing box 2, a servo motor 19 fixedly connected to the upper surface of the support block 18, a threaded rod 20 fixedly connected to the output end of the servo motor 19, an internal threaded cylinder 22 threadedly connected to the surface of the threaded rod 20, and a movable plate 21 fixedly sleeved on the surface of the internal threaded cylinder 22. The side of the movable plate 21 closest to the inner wall of the curing box 2 is slidably connected to the inner wall of the curing box 2. A first annular tube 14 is fixedly connected, and a through pipe 16 is fixedly connected to the back of the first annular tube 14. A second annular tube 17 is fixedly connected to the end of the through pipe 16 away from the first annular tube 14. Nozzles 15 are fixedly connected to the inner annular surfaces of both the first annular tube 14 and the second annular tube 17. Then, the servo motor 19 is turned on, and the servo motor 19 drives the threaded rod 20 to rotate. The rotation of the threaded rod 20 drives the moving plate 21 to move through the internal threaded cylinder 22. The movement of the moving plate 21 drives the second annular tube 17 and the first annular tube 14 to move respectively. When the second annular tube 17 moves to the leftmost position... When the side is moved, the servo motor 19 drives the moving plate 21 to move through the internal threaded cylinder 22. The movement of the moving plate 21 then drives the second annular tube 17 and the first annular tube 14 to move in opposite directions. A steam generator 9 is fixedly connected to the back of the curing box 2. A connecting pipe 11 is fixedly connected to the upper surface of the steam generator 9. The end of the connecting pipe 11 away from the steam generator 9 passes through the side of the support ring plate 1 and is fixedly connected to a corrugated pipe 12. By setting the corrugated pipe 12, axial, lateral, or angular expansion and contraction can be achieved through the corrugated structure of the pipe wall. When the first annular tube 14 is driven to move, the corrugated pipe... 12 can be stretched a distance. The end of the corrugated pipe 12 away from the connecting pipe 11 passes through the lower surface of the support ring plate 1 and the curing box 2 respectively and is fixedly sealed to the end of the first annular pipe 14. The surface of the connecting pipe 11 is fixedly fitted with an air valve 10. Then, the steam generator 9 is turned on and the steam generator 9 runs. After the water is vaporized, it enters the first annular pipe 14 through the connecting pipe 11 and the corrugated pipe 12. Then, it enters the second annular pipe 17 through the through pipe 16 from the first annular pipe 14. Then, it is sprayed out by the nozzles 15 on the first annular pipe 14 and the second annular pipe 17 respectively.
[0023] Reference Figure 1-4 A temperature sensor 13 is fixedly connected to the inner wall of the curing chamber 2. An inner groove 23 is formed on the upper surface of the curing chamber 2, and a heating wire 24 is fixedly connected to the inner wall of the inner groove 23. If the temperature inside the curing chamber 2 is too low, it will slow down the hydration reaction of the cement, leading to a longer curing period. If the temperature inside the curing chamber 2 is too high, the cement hydration reaction will be too fast, and the moisture will evaporate quickly, resulting in reduced strength and a loose structure. When the temperature sensor 13 detects that the temperature inside the curing chamber 2 is low, the heating wire 24 is turned on by an external controller. The heating wire 24 heats up and raises the temperature inside the curing chamber 2. When the temperature inside the curing chamber 2 is detected to be too high... When the heating wire 24 is turned off, the water mist vaporized by the steam generator 9 cools the curing box 2. A support frame 3 is fixedly connected to the side of the support ring plate 1. A horizontal rail 4 is fixedly connected to the upper surface of the support frame 3. A rotating wheel 5 is rotatably connected to the inner wall of the horizontal rail 4. A transport plate 6 is set on the upper surface of the rotating wheel 5. A precast concrete component 7 is set on the upper surface of the transport plate 6. The transport plate 6 is connected to an external traction device. When the external traction device is running, it pulls the transport plate 6. The transport plate 6 is pulled and moves through the rotating wheel 5. The movement of the rotating wheel 5 then moves the precast concrete component 7 into the curing box 2 for curing.
[0024] Reference Figure 2-4 A rubber strip 8 is fixedly connected to the top wall of the inner wall of the curing box 2. By setting the rubber strip 8, the two sides of the curing box 2 can be sealed when the concrete precast component 7 has not entered the curing box 2, so as to prevent the vaporized water mist from escaping from the two sides of the curing box 2. When the concrete precast component 7 moves into the curing box 2, the concrete precast component 7 pushes the rubber strip 8 open and enters the curing box 2. Afterwards, the rubber strip 8 returns to vertical position due to gravity to seal the curing box 2, reducing the occurrence of a large amount of vaporized water mist escaping from the inside of the curing box 2 during the transportation of the concrete precast component 7.
[0025] Reference Figure 2-4 There are six nozzles 15, with three nozzles 15 forming a group. The two groups of nozzles 15 are respectively set on the inner ring surface of the first annular pipe 14 and the second annular pipe 17. By setting the number of nozzles 15 to six, the water mist can quickly fill the entire curing box 2, and at the same time, the water mist can be evenly sprayed on the surface of the precast concrete component 7.
[0026] The implementation principle of the temperature- and humidity-adjustable precast concrete temperature-controlled curing box embodiment of this application is as follows: The steam generator 9 is then turned on. The steam generator 9 vaporizes the water and then it enters the first annular pipe 14 through the connecting pipe 11 and the corrugated pipe 12. Next, the water enters the second annular pipe 17 through the through-pipe 16 from the first annular pipe 14. Then, the water is sprayed out from the nozzles 15 on the first and second annular pipes 14 and 17 respectively. The servo motor 19 is then turned on, driving the threaded rod 20 to rotate. The rotation of the threaded rod 20 drives the moving plate 21 to move through the internal threaded cylinder 22. The movement of the moving plate 21 drives the second annular pipe 17 and the first annular pipe 14 to move respectively. When the second annular pipe 17 moves to the leftmost position, the servo motor 19 again drives the moving plate 21 to move through the internal threaded cylinder 22. The movement of the moving plate 21 then drives the second annular pipe 17 and the first annular pipe 14 to move in opposite directions, spraying the water into each area of the curing box, thus solving the problem of uneven steam distribution to a certain extent.
