Description

Technical Field

[0001] The invention relates to the technical field of microwave heating, and in particular to microwave rapid curing equipment and method for large-size concrete plate-shaped components. Background Art

[0002] With the development of prefabricated buildings, prefabrication factories have also attached great importance to the production efficiency of prefabricated components. Concrete curing is a crucial process link in the preparation and molding of components. Improving the early strength of concrete, accelerating the turnover rate of molds, and improving the production efficiency of prefabricated components are the key to improving quality and efficiency. Compared with the widely used thermal curing method, the heat energy of microwave curing is transferred from the inside of the concrete to the outside, so it has the advantages of low energy consumption, short demoulding time, and high curing efficiency. At present, most common concrete microwave curing equipment is a closed cavity mode, which serves small-sized laboratory specimens and cannot be used to maintain large plate-like prefabricated components. Therefore, the application of microwave curing technology urgently needs to invent a microwave curing equipment suitable for large concrete plate-like components. However, unlike small-sized specimens, during the microwave curing process of large-sized specimens, due to the large size of the microwaved concrete specimens, the radiation of the microwave emission source cannot be fully covered, which will cause overheating of the local area of ​​the specimen, and the interface problems caused by the difference in hydration process will lead to a decrease in the overall strength performance of the concrete slab.

[0003] Therefore, the present invention proposes a microwave rapid curing method and equipment for large concrete plate-like components. Through the adjustable movement of the microwave emission source, while ensuring the demoulding efficiency and meeting the mechanical properties of the components, the regional heating problem is eliminated to achieve efficient microwave curing. Summary of the invention

[0004] In view of the deficiencies in the prior art, the technical problem that the present invention intends to solve is to provide a microwave rapid curing equipment and method for large-sized concrete plate-like components, which can perform high-efficiency microwave curing on large-sized concrete plate-like components.

[0008] One end of the sliding track support rod is fixed to the bottom of the microwave curing bin, and the other end of the sliding track support rod is fixed to the sliding track. The sliding track support rod is hollow. The microwave motor dedicated wire is connected to the microwave motor on one hand, and the microwave motor dedicated wire is connected to the driving motor on the transverse rod along the sliding track support rod on the other hand. A plurality of microwave emission sources are evenly arranged at the lower part of the transverse rod. The driving motor can drive the transverse rod to drive the microwave emission source to reciprocate along the sliding track along the inlet and outlet directions of the microwave curing bin. The sliding track support rod does not interfere with the operation of the conveyor belt, and a concrete conveyor belt device is connected to the bottom of the microwave curing bin.

[0009] Microwave anti-leakage plates that can move up and down are arranged at the entrance and exit of the microwave curing chamber, and the microwave curing chamber itself is made of anti-microwave leakage materials; the control console is used to control the switch, time, power, and working environment of microwave curing;

[0010] The concrete conveyor belt device is in a trapezoidal structure as a whole, including inclined sections on both sides and a horizontal section in the middle. The horizontal section in the middle is wrapped within the inlet and outlet range of the microwave curing chamber, so that the concrete plate-shaped components to be cured remain horizontal in the microwave curing chamber; a water circulation and centrifugal wind integrated machine and a microwave motor are arranged below the outside of the microwave curing chamber; the circulating air supply pipe of the water circulation and centrifugal wind integrated machine and the water circulation pipe are both connected to the bottom of the microwave curing chamber, and a microwave leakage prevention plate is arranged at the connection position between the circulating air supply pipe and the water circulation pipe and the microwave curing chamber;

[0011] A water vapor humidity meter is installed in the microwave curing chamber to detect the water vapor content in the microwave curing chamber. On the top of the microwave curing chamber, multiple sets of infrared temperature detectors are installed at equal distances along the inlet and outlet directions of the microwave curing chamber to test the real-time temperature of different areas in the microwave curing chamber and alarm when abnormal temperature is detected. Multiple sets of infrared temperature detectors, water vapor humidity meters, microwave motors, water circulation and centrifugal wind integrated machines communicate with the control console.

[0012] Furthermore, a temperature probe is provided in the microwave curing chamber for detecting the internal temperature of the concrete plate-like member, and the temperature probe communicates with the control console through an additional infrared temperature detector.

[0013] Furthermore, a row of first gears are arranged at equal intervals along the import and export directions inside the sliding track 3, and two second gears are provided at both ends of the transverse rod. The two second gears are meshed with multiple first gears on the corresponding sides. Drive motors are installed on both sides of the transverse rod. The drive motors are transmitted to a second gear on the transverse rod on the corresponding side, and the drive motors are electrically connected to the dedicated wires for the microwave motors.

[0014] In a second aspect, the present invention provides a microwave rapid curing method for large-sized concrete plate-like components. The microwave emission source of the equipment used in the curing method is movably arranged, and the concrete plate-like components are transported to the microwave curing chamber by a conveyor belt.

[0015] After the large-size concrete slab is cast in the factory, the concrete slab-like components are moved and placed on the conveyor belt outside the microwave curing chamber. Buckles are placed on the conveyor belt to fix the concrete slab-like components. The static pre-curing interval time of the concrete slab-like components and the number of parts N that the concrete slab-like components need to be divided into are set. The distance P from the center line of the previous part that needs to be set is determined according to the following formula:

[0016] P=1 / N

[0017] Where, l represents the length of the concrete plate-like member;

[0018] Set the total microwave time and single microwave time for each portion;

[0019] Start the conveyor belt to convey the component to the microwave curing chamber. The concrete plate-like component remains stationary in the microwave curing chamber. When the microwave emission source is adjusted to the center line of the first part of the component, curing begins. The first part is close to the entrance of the microwave curing chamber and at the edge of the component. After it is completed, it automatically moves to the next part where the center line of the microwave emission source is at a distance P from the center line of the previous part. The static curing time of each part is the set single microwave time. When the overall microwave curing of the concrete plate-like component is completed once, the microwave emission source returns to the starting state. When the microwave emission source returns to the first part again, the time difference between the two returns to the first part is used as the interval time of microwave curing;

[0020] The number of cycles is determined according to the total microwave time of each part and the single microwave time. The early microwave curing task is completed after the number of cycles is reached.

[0021] Furthermore, the intermittent time is 30-60 min, preferably 30-35 min; the microwave heating power is 600W-1000W; the distance P from the center line of the previous part is 0.2-0.4m; the single microwave time is 1.5-2.5min, and the total microwave time is 14-20min; the number of parts N to be divided is 15-20.

[0022] Furthermore, the concrete plate-like component has a length of 6.0 to 4.0 m and a thickness of 0.10 to 0.20 m.

[0023] Preferably, the moving speed of the microwave emission source is 0.1 m / s.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention provides a microwave device for large concrete plate-like components, which can realize microwave curing of concrete plate-like components with a maximum length of 6m, a width of 3m, and a thickness of 0.2m. At the same time, the microwave is adjustable over a wide range, which solves the problem that the current microwave curing can only be performed on small or medium-sized components and is not suitable for microwave curing of large components.

[0026] 2. The microwave curing equipment of the present invention adopts an integrated design of conveying and curing. After the concrete plate-like components are placed on the conveyor belt, the conveyor belt moves them to the microwave curing chamber, eliminating the need for manual handling, thereby improving the overall efficiency of the curing work.

[0027] 3. The present invention adopts an intermittent microwave curing method to maintain large-sized concrete slabs, and proposes a microwave curing system for plate-like components of different sizes using a reciprocating microwave emission source. Compared with long-term continuous curing without interruption, the short-term interval curing method can achieve higher efficiency.

[0028] 4. The experiments of the present invention show that microwave curing can improve demoulding efficiency and mechanical properties compared with standard curing. The equipment of the present invention can better use microwaves to cure concrete plate-like components while performing microwave curing, which can better eliminate the heating problem of the area.

[0029] 5. The present invention is provided with a movable microwave emission source, which can make the specimen to be cured and the microwave emission source produce relative movement to eliminate the problem of regional heating of microwaves.

[0042] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0043] Example 1

[0044] In a typical embodiment of the present invention, a microwave rapid curing device for large-sized concrete plate-like components is provided, wherein the microwave emission source can be movably arranged, and the position is as follows: Figure 1 , Figure 2 and Figure 3 As shown, it includes a microwave curing chamber, a microwave emission source 2, a microwave emission source loading device, a concrete conveyor belt device and a control console. The microwave emission source loading device includes a sliding track 3, a transverse rod and a sliding track support rod 5. The two sliding track support rods 5 are connected to the bottom of the microwave curing chamber (the upper part of the conveyor belt), and the bottom of the microwave curing chamber is connected to the concrete conveyor belt device; the sliding track support rod is hollow, and the microwave motor dedicated wire 9 is connected to the microwave motor 6 on one hand, and the microwave motor dedicated wire 9 is connected to the transverse rod along the sliding track support rod 5 on the other hand, which can drive the transverse rod to drive the microwave emission source 2 to move along the sliding track.

[0045] Two sliding rails 3 are arranged on the inner side of the top of the microwave curing chamber along the inlet and outlet directions. The transverse rod can reciprocate on the sliding rails 3 along the inlet and outlet directions of the microwave curing chamber. The microwave emission source 2 is fixedly mounted on the transverse rods of the two sliding rails and can move back and forth on the sliding rails following the transverse rods. Microwave anti-leakage plates 1 that can move up and down are arranged at the inlet and outlet of the microwave curing chamber. The microwave curing chamber itself is made of anti-microwave leakage materials. The control console is used to adopt industrial electrical automation PLC control and touch screen operation, and can control the switch, time, power, etc. of microwave curing.

[0046] The concrete conveyor belt device includes a conveyor belt 4 and a guide roller connected to the conveyor belt. The concrete conveyor belt device is an overall trapezoidal structure, including inclined sections on both sides and a horizontal section in the middle. The horizontal section in the middle is wrapped within the inlet and outlet range of the microwave curing chamber, so that the concrete plate-like components to be cured remain horizontal in the microwave curing chamber. A water circulation and centrifugal wind integrated machine 7 (the water circulation and centrifugal wind of the water circulation and centrifugal wind integrated machine are connected to the microwave curing chamber, and the water circulation part is also connected to the water tank of the external factory) and a microwave motor 6 are arranged below the outside of the microwave curing chamber, both of which can be directly fixed on the ground. The circulating air supply pipe of the water circulation and centrifugal wind integrated machine and the water circulation pipe are both connected to the bottom of the microwave curing chamber, and a microwave leakage prevention plate is arranged at the connection position between the circulating air supply pipe and the water circulation pipe and the microwave curing chamber. In this embodiment, the water circulation part of the water circulation and centrifugal wind integrated machine 7 is connected to an external cooling water tank, and the cooling water tank is connected to an external water source in the factory. The external water source transports cooling water to the cooling water tank, and the microwave curing chamber is cooled by the water in the cooling water tank. A water vapor humidity meter is set in the chamber to detect the water vapor content in the microwave curing chamber, and continuously adjust the water vapor concentration required for the initial set concrete type and its curing. In the process of the hot water vapor being taken away, the cold water and the steam perform heat exchange to prevent the high-temperature water vapor in the curing chamber from heating the concrete secondary and affecting the strength, thereby forming a water cooling circulation system.

[0047] At the top of the microwave curing chamber, multiple groups of infrared temperature detectors are installed at equal distances along the inlet and outlet directions of the microwave curing chamber to test the real-time temperature of different areas in the microwave curing chamber. Multiple groups of infrared temperature detectors are arranged in two rows in the radiation area symmetrically according to the width of the microwave curing chamber. Multiple groups of infrared temperature detectors communicate with the control console to monitor temperature anomalies and alarm. The temperature of different areas can also be obtained to detect temperature changes in different curing positions. Each infrared temperature detector can transmit the temperature it detects to the control console. When the control console senses that the temperature exceeds the normal temperature, the system automatically stops heating to prevent the strength of the concrete plate-like components from being affected. At the same time, after the curing is completed, the temperature in the curing chamber is detected so that the subsequent water circulation and centrifugal wind integrated machine 7 can adjust the state in the chamber to a normal state (reaching the outdoor atmospheric pressure and the water vapor content is the same as the outside world). At the same time, experiments can be conducted to explore the effect of microwaves. Under concrete of the same or different materials, under the application of microwaves at different positions (the microwave emission source is movable), the temperature field states at different positions can be explored. Temperature probes can also be inserted into the places on the concrete plate-like components where the temperature needs to be detected, and connected to an additional infrared temperature detector 8 to detect the temperature changes inside each part, so as to further explore the temperature field experiment.

[0048] The microwave leakage prevention plate 1 adopts a stainless steel inductive suppression sheet, which can complete the tasks of reflection and absorption.

[0049] like Figure 1 and Figure 5 As shown, after the large-size concrete slab is cast in the factory, a crane is used to move the concrete plate-like component and place it on a conveyor belt outside the microwave curing chamber. A buckle is placed on the conveyor belt to fix the concrete plate-like component. The staff sets the static pre-curing time of the concrete plate-like component in front of the console, and the static pre-curing time is 30 minutes. Then the conveyor belt is started, and the number of parts required to divide the concrete plate-like component is set (a total of 15 parts in this embodiment). The microwave leakage prevention plate on the inlet side of the microwave curing chamber is opened upward, and the concrete plate-like component can enter the microwave curing chamber through the conveyor belt for curing. After the concrete plate-like component completely enters the microwave curing chamber, the microwave leakage prevention plate on the inlet side is lowered to ensure that the microwave in the microwave curing chamber is not leaked. After the concrete is transferred to the microwave curing chamber, the chamber door is closed. The time the concrete is left standing in the microwave curing chamber is called the pre-curing time, which can be from half an hour to one hour. Then it can be cured. The system is divided into fifteen parts according to the size of the concrete plate-like components. The concrete plate-like components remain stationary in the microwave curing chamber. The microwave emission source performs reciprocating motion in the fifteen parts, radiating intermittently in each part. When the microwave action duration of each part reaches the total microwave duration, the curing is completed.

[0050] The total length of the horizontal projection of the concrete conveyor belt device is 8m, the total height from the lowest point of the concrete conveyor belt device to the highest point of the microwave curing chamber is 1.8m, and the total width is 3.5m; the length in the inlet and outlet directions of the microwave curing chamber is 6.5m, the height from the concrete conveyor belt device in the microwave curing chamber to the top surface of the microwave curing chamber is 0.8m, and the internal width of the microwave curing chamber is 3.2m.

[0051] In this embodiment, the microwave emission source adopts a rectangular microwave generator, the total length of the sliding track 3 is 6.3m, and a 6.3m*10cm*10cm hollow steel pipe is adopted. Two sliding tracks are set, and the lateral distance between the two sliding tracks is 3m. The length of the transverse rod is 3.1m. The two ends of the transverse rod slide in cooperation with the two sliding tracks. A number of microwave emission sources are carried on the lower surface of the transverse rod (three microwave emission sources are set in this embodiment), the longest length between the microwave emission sources at both ends is 2.5m, and the width of a single microwave emission source is 0.2m. The above setting can fully support the weight of the microwave emission source. The power of the microwave source can reach up to 60KW. Due to the long heating and duration of microwaves, the water circulation and centrifugal wind integrated machine 7 will continue to operate to ensure the stable water vapor balance and pressure balance in the warehouse.

[0052] The water circulation and centrifugal wind integrated machine 7 uses a 3kW centrifugal fan to maintain the system pressure and a 1.2kW water circulation pump. A microwave leakage prevention plate is installed at the bottom of the microwave curing chamber to seal the centrifugal fan and the four pipe openings at the bottom of the microwave curing chamber. Six sets of infrared temperature detectors are installed at equal distances inside the microwave curing chamber to measure the surface temperature of the components inside the chamber and transmit the internal temperature to the external control console to ensure that the equipment can be automatically protected when the temperature in any area is abnormal. The infrared temperature detector located on the top of the microwave curing chamber will continuously transmit the internal temperature information to the control console.

[0053] The microwave motor 6 is connected to a dedicated wire 9 for the microwave motor, and the dedicated wire 9 for the microwave motor passes through the sliding track support rod 5 and is connected to the upper transverse rod, which is used to control the movement of the microwave emission source. A row of first gears are arranged at equal intervals along the import and export directions inside the sliding track 3, and two second gears are provided at both ends of the transverse rod. The two second gears are meshed with multiple first gears on the corresponding sides. Drive motors are installed on both sides of the transverse rod. The drive motor is driven by a second gear on the transverse rod on the corresponding side, and the drive motor is electrically connected to the dedicated wire for the microwave motor at the same time. The movement method adopts the motor movement of the gear, which can realize reciprocating and intermittent motion, and has stronger stability. The microwave emission source can be controlled to move forward and backward by controlling the drive motor. Figure 8 .

[0054] The setting power of the microwave emission source can be adjusted according to the specific concrete type to ensure that the microwave curing power demand of any concrete is within the normal use power range. A water circulation and centrifugal fan integrated machine is set to maintain the internal pressure and water circulation stability. After the microwave curing is completed, the microwave emission source stops operating, the microwave in the chamber disappears, and the microwave leakage prevention plate at the exit of the microwave curing chamber opens to transmit the concrete plate-like components out of the microwave curing chamber. After the curing is completed, the internal water source circulation pump and centrifugal fan are automatically closed after being adjusted to the normal state in the chamber (the air pressure and water vapor content reach the external state).

[0055] The microwave curing system of the large-sized components in the present invention adopts intermittent curing, which can control the temperature rise rate and stabilize the strength development trend of concrete, thereby avoiding the problem of uneven strength development caused by differences in local superheated water heating rates to a certain extent. The parameters for controlling microwave curing efficiency include microwave power, total microwave time, single microwave time, and microwave intermittent time.

[0056] After the concrete slab-like components enter the curing chamber, external staff set the power of the movable microwave emission source according to the size and material type of the components in the chamber, adjust its moving speed and stationary time, and set it according to the length and thickness of the concrete slab. The specific setting parameters are shown in Table 1. The maximum concrete slab that can be cured by microwave is 6m in length and 0.2m in width.

[0057] Table 1 Parameter selection of concrete plate components in equipment

[0058]

[0059] The selected parameters in the table are expressed as power - distance from the center line of the previous part - single microwave time - total microwave time.

[0060] Take a 6m long 0.2m thick plate as an example, divide it into 15 parts along the length direction, and start curing when the microwave emission source is adjusted to the first part of the component. The first part is close to the entrance of the microwave curing chamber and at the edge of the component. After it is completed, it automatically moves to the next part where the center line of the microwave emission source is 0.4m away from the center line of the previous part. The default microwave emission source movement rate is 0.1m / s, and the static curing time of each part is 2 minutes. After completing an overall microwave curing (i.e. moving from one side of the component to the other side and then returning to the starting side), the microwave emission source returns to the starting state (near the entrance of the microwave curing chamber, i.e. the edge of the first part) at a speed of 0.1m / s. When the microwave emission source returns to the first part again, the time difference between the two returns to the first part can be used as the interval time of microwave curing, and the interval time is 30 minutes. A total of 9 cycles are performed to complete the early microwave curing task. The heating time for the same position during the 9 cycles is a total of 18 minutes. At this time, the strength development trend of microwave curing and standard curing after pre-curing for 6h, 12h, 1d, 3d, 7d, and 28d can be found in Fig. 9 .

[0061] When the length is less than 6m, the size and power can be selected according to the parameters in Table 1. Each parameter can ensure that the microwave intermittent time reaches 30 to 35 minutes. The present invention can also be changed according to the actual conditions such as the length and thickness of the component, and the microwave power, single microwave time, total microwave time, and intermittent time can be adjusted. The intermittent time does not need to be exactly the same, and it can be within the approximate range of the intermittent maintenance intermittent time. The moving speed of the microwave emission source has little effect on the overall.

[0062] The intermittent maintenance in this application refers to the pause between adjacent cycles on the one hand, and the pause during the movement to the next part center distance in one cycle on the other hand. The microwave emission source is set at the central axis position of each part and moves, radiating from the center to the periphery.

[0063] The length dimensions in Table 1 are the common dimensions of concrete slabs in component factories, but irregular lengths may occur. For concrete of different lengths, the interval time should be 30 minutes while completing the curing task of each part. Assuming the length of the concrete slab is l, the distance from the center line of the previous part to be set is determined according to the following formula:

[0064] Distance from the center line of the previous part (m) = l / 15

[0065] l represents the length of the concrete slab. For example, for a 6m long concrete slab, 6 / 15=0.4, then 0.4m is the distance from the center line of the upper part.

[0066] Any matters not described in the present invention are applicable to the prior art.
