Description

Technical Field

[0001] This application relates to the field of concrete curing technology, and in particular to a constant temperature curing device for precast concrete components. Background Technology

[0002] Precast concrete components are commonly used materials in modern construction projects. In the production process of precast concrete components, the curing process plays a decisive role in the final performance of the components, directly affecting the strength development, durability improvement and appearance integrity of the components. Its quality directly affects the safety and durability of building structures.

[0003] In existing technologies, steam equipment is commonly used in the curing devices for precast concrete components. However, the location of the exhaust pipe is usually fixed, and the entire concrete storage area can only be humidified by the natural diffusion of water vapor. This method not only leads to uneven distribution of water vapor, which cannot meet the uniform humidity requirements of precast concrete components, but also cannot meet the requirement of fixed-point humidification at different locations of precast concrete components, resulting in a waste of resources.

[0004] Therefore, this application provides a constant temperature curing device for precast concrete components. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a constant temperature curing device for precast concrete components, which overcomes the deficiencies of existing technologies. It aims to solve the problem that existing curing devices for precast concrete components often use steam equipment, but the location of its exhaust pipe is usually fixed. It can only rely on the natural diffusion of water vapor to humidify the entire concrete storage area. This method not only leads to uneven distribution of water vapor, which cannot meet the uniform humidity requirements of precast concrete components, but also cannot meet the need for fixed-point humidification of different locations of precast concrete components, resulting in a waste of resources.

[0006] To achieve the above objectives, this application provides the following technical solution: a constant temperature curing device for precast concrete components, comprising a box body, an electric temperature control layer fixedly installed inside the wall of the box body, a receiving plate slidably connected inside the box body, two sets of main pipes symmetrically arranged inside the box body, three sets of spray heads fixedly installed vertically on one side of each main pipe, an adjustment mechanism above the main pipe, a dual-head steam generator fixedly installed at the top of the box body, steam delivery pipes installed between both ends of the dual-head steam generator and the two sets of main pipes, solenoid valves installed inside the spray heads and steam delivery pipes, a temperature detector fixedly installed on the inner wall of the box body, three sets of humidity detectors sequentially installed from top to bottom on one side of the inner wall of the box body located at the temperature detector, a controller fixedly installed on one side of the box body, and the controller electrically connected to the temperature detector, humidity detector, dual-head steam generator, adjustment mechanism, and solenoid valves.

[0007] By adopting the above technical solution, the internal temperature of the chamber is detected by a temperature detector, and the signal is fed back to the controller. The controller controls the electric temperature control layer to achieve constant temperature control inside the chamber. Three sets of humidity detectors can monitor the humidity data at different locations inside the chamber in real time. Based on the data fed back by the three sets of humidity detectors, the controller controls the opening of the solenoid valves in the corresponding steam delivery pipes and spray heads. Then, according to the humidification requirements of the precast concrete components placed above the receiving plate, the chamber is humidified at specific points. The angle of the spray head can be adjusted with the adjustment mechanism. At the same time, since multiple sets of spray heads are set up inside the chamber and distributed along the main pipe, the dual-head steam generator is activated to make water vapor quickly and evenly distributed inside the chamber. This satisfies both the humidity uniformity requirements of the precast concrete components and the humidification requirements of different locations on the precast concrete components, avoiding waste of resources and improving the flexibility of use.

[0008] As a preferred embodiment of this application, the adjustment mechanism includes two sets of fixing frames, both sets of fixing frames being fixedly installed on the inner wall of the housing. The main pipe is disposed between the corresponding two sets of fixing frames, and a connecting pipe is fixedly installed at the bottom end of the main pipe. The connecting pipe is rotatably connected to the corresponding fixing frame and the steam conveying pipe. Two sets of reciprocating motors are fixedly installed at the top end of the housing. A rotating shaft is installed between the reciprocating motor and the corresponding main pipe, and the rotating shaft is rotatably connected to the corresponding fixing frame. The reciprocating motor is electrically connected to the controller.

[0009] By adopting the above technical solution, and using the data fed back by humidity detectors at different locations on the controller, when it is necessary to focus on humidifying a certain area or adjust the humidification position, the reciprocating motor is started. The reciprocating motor drives the main pipe to rotate between two sets of fixed brackets through the rotating shaft, thereby changing the spray direction and position of the spray head, realizing point-to-point humidification of different locations, improving the flexibility of use and the curing effect on precast concrete components.

[0010] As a preferred technical solution of this application, two sets of slide rails are fixedly installed on the inner wall of the box below the receiving plate. The sliding end of the slide rail is slidably connected to a slider, and the top ends of the two sets of sliders are fixedly installed to the bottom end of the receiving plate.

[0011] By adopting the above technical solution, the receiving plate can slide inside the box through the slide rail and slider. When placing or removing precast concrete components, the receiving plate can be pulled out of the box, which is beneficial to the convenience of operators when placing and moving precast concrete components.

[0012] As a preferred technical solution of this application, several sets of drainage grooves are provided on the side of the two sets of slide rails that are far apart, a liquid collection chamber is provided at the bottom of the box below the receiving plate, and a liquid collection mechanism is provided on one side of the box.

[0013] By adopting the above technical solution, during the curing process, the condensate and other liquids generated on the inner wall of the box flow into the liquid collection chamber through the drainage channel. The liquid collection mechanism can collect the liquid in the liquid collection chamber and discharge it from the box, avoiding the accumulation of liquid in the box and affecting the humidity and temperature inside the box, which is conducive to improving the curing quality of precast concrete components.

[0014] As a preferred embodiment of this application, the liquid collection mechanism includes a support plate, which is fixedly installed on one side of the housing. A liquid collection cylinder is fixedly installed on the top of the support plate, and a liquid pump is fixedly installed on the top of the support plate on one side of the liquid collection cylinder. A suction pipe is connected between the suction end of the liquid pump and the housing, and a delivery pipe is connected between the discharge end of the liquid pump and the top of the liquid collection cylinder. A delivery pipe is connected between the input end of the dual-head steam generator and the liquid collection cylinder.

[0015] By adopting the above technical solution, the liquid in the collection chamber is extracted by a pump through a pumping pipe, and then transported to the collection cylinder through a delivery pipe for collection. When the dual-head steam generator is working, it extracts the liquid in the collection cylinder through a delivery pipe, which helps to save water resources and reduce maintenance costs.

[0016] As a preferred embodiment of this application, a water filter is installed in the middle of the infusion tube.

[0017] By adopting the above technical solution, the liquid passing through the infusion pipe is filtered through a water filter to remove impurities and solid particles from the liquid, thereby improving the quality of the liquid delivered to the collection cylinder and the dual-head steam generator. This helps to prevent impurities from entering the dual-head steam generator and improves the protection effect of the dual-head steam generator.

[0018] As a preferred technical solution of this application, a door is hinged to one side of the box body, an air duct is fixedly installed on the top of the door, and an exhaust fan is fixedly installed inside the air duct.

[0019] By adopting the above technical solution, during the maintenance process, when the temperature inside the chamber is high, the hot air inside the chamber is quickly extracted through the air duct by starting the exhaust fan. After the exhaust fan stops operating, the cold air enters the chamber through the air duct, which helps to maintain the temperature inside the chamber.

[0020] As a preferred technical solution of this application, a guide plate is fixedly installed at the bottom of the box body below the receiving plate, and two sets of support blocks are fixedly installed between the inner wall of the box body and the bottom wall of the slide rail.

[0021] By adopting the above technical solution, the liquid dripping to the bottom of the tank can be better guided to one side of the suction pipe through the guide plate, which is beneficial to the liquid discharge efficiency. The support block can support the slide rail, which enhances the stability of the slide rail and the receiving plate.

[0022] The beneficial effects of this application are:

[0023] 1. The internal temperature of the chamber is detected by a temperature detector, and the signal is fed back to the controller. The controller controls the electric temperature control layer to achieve constant temperature control inside the chamber. Three sets of humidity detectors can monitor the humidity data at different locations inside the chamber in real time. Based on the data fed back by the three sets of humidity detectors, the controller controls the opening of the solenoid valves in the corresponding steam delivery pipes and spray heads. Then, according to the humidification requirements of the precast concrete components placed above the receiving plate, the chamber is humidified at specific points. The angle of the spray head can be adjusted with the adjustment mechanism. At the same time, since multiple sets of spray heads are set up inside the chamber and distributed along the main pipe, the dual-head steam generator is activated to make water vapor quickly and evenly distributed inside the chamber. This satisfies both the humidity uniformity requirements of the precast concrete components and the humidification needs of different locations on the precast concrete components, avoiding waste of resources and improving the flexibility of use.

[0024] 2. Based on the data fed back by humidity detectors at different locations on the controller, when it is necessary to focus on humidifying a certain area or adjust the humidification position, the reciprocating motor is started. The reciprocating motor drives the main pipe to rotate between two sets of fixed brackets through the rotating shaft, thereby changing the spray direction and position of the spray head, realizing point-to-point humidification of different locations, improving the flexibility of use and the curing effect on precast concrete components.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Reference Figure 1-4A constant temperature curing device for precast concrete components includes a housing 1. An electric temperature control layer 2 is fixedly installed inside the wall of the housing 1. A receiving plate 3 is slidably connected inside the housing 1. Two sets of main pipes 4 are symmetrically arranged inside the housing 1. Three sets of spray heads 401 are fixedly installed vertically on one side of each main pipe 4. An adjusting mechanism 5 is installed above the main pipes 4. A double-headed steam generator 6 is fixedly installed at the top of the housing 1. Steam delivery pipes 7 are installed between both ends of the double-headed steam generator 6 and the two sets of main pipes 4. Electric... A solenoid valve is used. A temperature detector 8 is fixedly installed on the inner wall of the housing 1. Three humidity detectors 9 are installed from top to bottom on one side of the inner wall of the housing 1, located on the side of the temperature detector 8. A controller 18 is fixedly installed on one side of the housing 1. The controller 18 is electrically connected to the temperature detector 8, humidity detectors 9, dual-head steam generator 6, regulating mechanism 5, and solenoid valve. Two sets of slide rails 10 are fixedly installed on the inner wall of the housing 1 below the receiving plate 3. The sliding end of the slide rail 10 is slidably connected to a slider 11. The top of the two sets of sliders 11 are fixedly installed to the bottom of the receiving plate 3.

[0032] Temperature detector 8 detects the internal temperature of chamber 1 and sends the signal back to controller 18. Controller 18 controls the temperature control layer 2 to achieve constant temperature control inside chamber 1. Three sets of humidity detectors 9 monitor humidity data at different locations (top, middle, and bottom) inside chamber 1 in real time. Based on the data from the three humidity detectors 9, controller 18 controls the opening of the corresponding solenoid valves in the steam delivery pipe 7 and spray head 401. Then, according to the humidification requirements of the precast concrete components placed above the receiving plate 3, targeted humidification is achieved inside chamber 1. In conjunction with the adjustment mechanism 5, the spray head 401 can be adjusted... The angle can be adjusted. At the same time, since multiple sets of spray heads 401 are installed in the box 1 and distributed up and down along the main pipe 4, the double-head steam generator 6 is started, so that water vapor is quickly and evenly distributed in the box 1. This satisfies the requirements of precast concrete components for humidity uniformity and also meets the humidification needs of different positions of precast concrete components, avoiding waste of resources and improving the flexibility of use. The receiving plate 3 can slide in the box 1 through the slide rail 10 and the slider 11. When placing or taking out precast concrete components, the receiving plate 3 can be pulled out of the box 1, which is beneficial to the convenience of operators when placing and moving precast concrete components.

[0033] Reference Figure 1-3The adjusting mechanism 5 includes two sets of fixed brackets 501, both of which are fixedly installed on the inner wall of the box 1. The main pipe 4 is located between the corresponding two sets of fixed brackets 501. A connecting pipe 502 is fixedly installed at the bottom end of the main pipe 4. The connecting pipe 502 is rotatably connected to the corresponding fixed bracket 501 and the steam conveying pipe 7. Two sets of reciprocating motors 504 are fixedly installed at the top of the box 1. A rotating shaft 503 is installed between the reciprocating motor 504 and the corresponding main pipe 4. The rotating shaft 503 is rotatably connected to the corresponding fixed bracket 501. The reciprocating motor 504 is electrically connected to the controller 18. Several sets of drainage grooves 12 are opened on the side of the two sets of slide rails 10 that are far apart. A liquid collection chamber 13 is set at the bottom of the box 1 below the receiving plate 3. A liquid collection mechanism 14 is set on one side of the box 1.

[0034] Based on the data fed back by the humidity detectors 9 at different positions of the controller 18, when it is necessary to focus on humidifying a certain area or adjust the humidification position, the reciprocating motor 504 is started. The reciprocating motor 504 drives the main pipe 4 to rotate between the two sets of fixed brackets 501 through the rotating shaft 503, thereby changing the spray direction and position of the spray head 401, realizing point-to-point humidification of different positions, improving the flexibility of use and the curing effect of precast concrete components. During the curing process, the condensate and other liquids generated on the inner wall of the box 1 flow into the liquid collection chamber 13 through the drainage channel 12. The liquid collection mechanism 14 can collect the liquid in the liquid collection chamber 13 and discharge it from the box 1, avoiding the accumulation of liquid in the box 1, which would affect the humidity and temperature inside the box 1, and is conducive to improving the curing quality of precast concrete components.

[0035] Reference Figure 1-4The liquid collection mechanism 14 includes a support plate 1401, which is fixedly installed on one side of the housing 1. A liquid collection cylinder 1402 is fixedly installed on the top of the support plate 1401. A liquid pump 1403 is fixedly installed on the top of the support plate 1401 on one side of the liquid collection cylinder 1402. A suction pipe 1404 is connected between the suction end of the liquid pump 1403 and the housing 1. A delivery pipe 1405 is connected between the discharge end of the liquid pump 1403 and the top of the liquid collection cylinder 1402. A delivery pipe 19 is connected between the input end of the dual-head steam generator 6 and the liquid collection cylinder 1402. A door 101 is hinged to one side of the housing 1. An air duct 1 is fixedly installed on the top of the door 101. 6. An exhaust fan 17 is fixedly installed inside the duct 16. The liquid in the collection chamber 13 is extracted by the liquid pump 1403 through the extraction pipe 1404, and then transported to the collection cylinder 1402 for collection through the delivery pipe 1405. When the dual-head steam generator 6 is working, it extracts the liquid in the collection cylinder 1402 through the delivery pipe 19, which helps to save water resources and reduce maintenance costs. During the maintenance process, when the temperature inside the box 1 is high, the hot air inside the box 1 is quickly extracted through the duct 16 by starting the exhaust fan 17. After the exhaust fan 17 stops working, the cold air enters the box 1 through the duct 16, which helps to maintain the temperature inside the box 1.

[0037] Working principle: The temperature inside the chamber 1 is detected by the temperature detector 8 and the signal is fed back to the controller 18. The controller 18 controls the electric temperature control layer 2 to achieve constant temperature control inside the chamber 1. Three sets of humidity detectors 9 can monitor the humidity data at different positions in the upper, middle and lower parts of the chamber 1 in real time. According to the data fed back by the three sets of humidity detectors 9, the controller 18 controls the opening of the solenoid valve in the corresponding steam delivery pipe 7 and the spray head 401. Then, according to the humidification requirements of the precast concrete components placed above the support plate 3, the chamber 1 is humidified at specific points. The angle of the spray head 401 can be adjusted with the adjustment mechanism 5. At the same time, since multiple sets of spray heads 401 are set in the chamber 1 and distributed up and down along the main pipe 4, the dual-head steam generator 6 is started to make water vapor quickly and evenly distributed in the chamber 1.

[0038] The receiving plate 3 can slide inside the box 1 via the slide rail 10 and the slider 11. When placing or removing precast concrete components, the receiving plate 3 can be pulled out of the box 1. During the curing process, the condensate and other liquids generated on the inner wall of the box 1 flow into the liquid collection chamber 13 through the drainage channel 12.
