Description

Technical Field

[0001] This invention relates to the field of precast concrete curing technology, specifically a device and process for carbon dioxide gas-solid mineralization curing of precast concrete. Background Technology

[0002] Carbon dioxide gas-solid mineralization curing of concrete is a technology that utilizes carbon dioxide to react with the calcium and magnesium components in concrete, thereby increasing the strength and durability of concrete by generating products such as calcium carbonate, while simultaneously sequestering carbon dioxide.

[0003] In the production of precast concrete components, although the components already possess a certain strength and structure in the early hydration and forming stage, further curing treatment is required through carbon dioxide mineralization curing technology to improve their strength and durability.

[0004] Currently, when curing precast concrete components, the precast components are placed into a CO2 curing autoclave after molding. The CO2 curing autoclave has a platform for receiving the precast components. During the curing process, the contact surface between the precast component and the platform will cause partial obstruction of the precast component, making it impossible to guarantee the comprehensiveness of the curing treatment. Subsequently, the placement position of the precast component may need to be changed by the staff, which complicates the curing process. Alternatively, the following curing equipment is equipped with corresponding clamping mechanisms to clamp the side of the precast component. Although this can expose most of the precast component, the clamped area is still not fully exposed, and the clamping position needs to be changed later to complete the complete curing treatment. Summary of the Invention

[0005] The purpose of this invention is to provide an apparatus and process for carbon dioxide gas-solid mineralization curing of precast concrete components, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A device for carbon dioxide gas-solid mineralization curing of precast concrete components includes a housing and two horizontal shafts rotatably installed inside the housing and arranged opposite to each other, wherein one of the horizontal shafts is connected to the output end of a second drive motor installed on the side of the housing.

[0008] The device for carbon dioxide gas-solid mineralization curing of precast concrete components also includes:

[0009] A frame is disposed between the two horizontal axes, and two sets of support mechanisms are provided on the frame along the vertical direction. The two sets of support mechanisms move in opposite directions and are used to support the prefabricated parts to be processed located in the frame.

[0010] A circulating gas supply mechanism is located inside the box and above the frame. The circulating gas supply mechanism can move along the length of the box inside the box to pump carbon dioxide gas to the prefabricated part to be processed.

[0011] The elastic limiting mechanism is provided on each of the two horizontal axes. The elastic limiting mechanism is triggered when the circulating air supply mechanism moves along the length of the box body, and can move from the side of the frame to above the precast part, and then perform a clamping action on the precast part.

[0012] As a further aspect of the present invention: the supporting mechanism includes multiple deflection structures mounted on the frame, the deflection structure including a first drive motor mounted on the side of the frame and a support plate disposed at the end of the output shaft of the first drive motor, and the frame is also provided with an opening for the support plate to move.

[0013] As a further embodiment of the present invention: the circulating gas supply mechanism includes two transverse plates symmetrically and movably disposed within the housing, the two transverse plates being connected to two sets of threaded drive assemblies disposed within the housing, and the transverse plates being provided with a gas guiding structure.

[0014] As a further embodiment of the present invention: the gas guiding structure includes an inclined plate rotatably mounted on the transverse plate, multiple conduits disposed on the transverse plate, and a flat nozzle connected to the conduits and located on the side of the inclined plate;

[0015] The inclined plate is provided with multiple air passages at equal intervals on the side facing the flat nozzle. The rotation shaft of the inclined plate is connected to a deflection control structure. The deflection control structure is triggered when the transverse plate moves to the end of its stroke and can cause the inclined plate to perform a deflection action.

[0016] As a further embodiment of the present invention: the deflection control structure includes a fixed round rod fixedly installed in the housing and two driven tubes respectively rotatably installed on the two transverse plates. The two driven tubes are slidably fitted with the fixed round rod, and the driven tubes are connected to the rotation shaft of the inclined plate through a bevel gear set and a transmission belt.

[0017] The fixed round rod has a groove on its outer wall and a protrusion on its inner wall that is adapted to the groove. The protrusion extends into the groove and is slidably connected to the fixed round rod. The groove includes a first sliding groove and a second sliding groove connected together. The first sliding groove is arranged along the axial direction of the fixed round rod, and the second sliding groove is arranged spirally on the fixed round rod.

[0018] As a further embodiment of the present invention: the elastic limiting mechanism includes a first sleeve and a second sleeve slidably sleeved on the horizontal axis, a strip-shaped protrusion is formed on the horizontal axis, and the inner walls of the first sleeve and the second sleeve are provided with strip-shaped grooves adapted to the strip-shaped protrusion.

[0019] The outer periphery of the horizontal shaft is also fitted with a first cylindrical spring. The two ends of the first cylindrical spring are respectively connected to the first sleeve and the second sleeve. The second sleeve is provided with two sets of elastic pressure components. The first sleeve is connected to the booster component located in the box body. The booster component cooperates with the horizontal moving plate.

[0020] As a further embodiment of the present invention: the booster assembly includes an L-shaped guide rail disposed on the inner wall of the housing, and a first slider and a second slider slidably fitted on the guide rail. The second slider is rotatably connected to the first sleeve through a fixed arm. Two sets of sliding clearance structures are provided between the first slider and the transverse plate. A connecting rod is also provided between the first slider and the second slider, and the two ends of the connecting rod are respectively hinged to the first slider and the second slider.

[0021] As a further embodiment of the present invention: the sliding clearance structure includes a follower plate fixed to the first slider via a connecting arm and a column fixed at the end of the transverse plate. The follower plate is provided with a guide groove adapted to the column. The column passes through the guide groove and is slidably connected to the follower plate. The guide groove includes a first through groove and a second through groove connected together. The first through groove is arranged along the length direction of the follower plate, and the second through groove is inclined.

[0022] As a further embodiment of the present invention: the elastic pressure application component includes a guide plate disposed on the second sleeve, a driven plate slidably fitted with the guide plate, a transmission plate fixed on the driven plate, two fastening rods fixed on the first sleeve, a gap adapted to the transmission plate reserved between the two fastening rods, a drive column fixedly disposed in the gap, an inclined groove adapted to the drive column provided on the transmission plate, the drive column passing through the inclined groove and slidably connected to the transmission plate;

[0023] The driven plate is also slidably provided with two connecting columns. One end of the two connecting columns facing the horizontal axis is fixedly connected to a pressure plate, and a second columnar spring is sleeved on the outer periphery of the connecting columns. The two ends of the second columnar spring are respectively connected to the driven plate and the pressure plate.

[0024] A carbon dioxide gas-solid mineralization curing process for precast concrete components, using the aforementioned apparatus, includes the following steps:

[0025] Step 1: Place the precast component to be processed into the frame, support the precast component with the supporting mechanism, seal the box, and inject carbon dioxide gas.

[0026] Step 2: The external pump operates, and the circulating gas supply mechanism moves along the length of the chamber, circulating and pumping the carbon dioxide gas in the chamber.

[0027] Step 3: The deflection control structure and the elastic limiting mechanism are triggered. The elastic limiting mechanism moves above the precast component and performs a clamping action on the precast component. The deflection control structure switches the tilting state of the tilting plate to the horizontal state.

[0028] Step four: The frame drives the prefabricated parts to flip over, and the circulating gas supply mechanism continues to circulate carbon dioxide gas.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] During the curing process, the precast components are placed inside the frame, and multiple sets of support mechanisms support the bottom of the precast components, allowing for large-area exposure of the precast components. Furthermore, the frame can be flipped during the curing process to allow the precast components to be turned over, ensuring comprehensive curing treatment.

[0031] Secondly, in this device, before the frame drives the precast component to flip each time, the elastic limiting mechanism can flexibly clamp the precast component, avoiding collisions between the precast component and the frame during the flipping process, which would cause damage and deviation in the position of the precast component within the frame. This provides comprehensive protection for the precast component and ensures uniform subsequent curing. Moreover, compared to rigid clamping, flexible clamping can effectively avoid damage to the precast component caused by clamping force.

[0032] In addition, carbon dioxide gas is blown onto the inclined plate through flat nozzles, and the carbon dioxide gas is divided by multiple ventilation pipes, which makes the distribution of carbon dioxide gas more uniform and realizes the circulation of carbon dioxide gas in the box. At the same time, in conjunction with the frame to drive the precast components to rotate, it can effectively improve the sufficiency of the mineralization reaction between carbon dioxide gas and alkaline components such as calcium and magnesium in concrete, and ensure the effect of curing treatment of precast concrete components.

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Furthermore, elements in this invention are referred to as being "disposed on" or "located on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0047] Please see Figures 1-11 In this embodiment of the invention, a device for carbon dioxide gas-solid mineralization curing of precast concrete includes a housing 1 and two horizontal shafts 2 rotatably installed inside the housing 1 and arranged opposite to each other, wherein one of the horizontal shafts 2 is connected to the output end of a second drive motor 6 installed on the side of the housing 1.

[0048] The device for carbon dioxide gas-solid mineralization curing of precast concrete components also includes:

[0049] The frame 3 is disposed between the two horizontal axes 2, and the frame 3 is provided with two sets of support mechanisms along the vertical direction. The two sets of support mechanisms move in opposite directions and are used to support the prefabricated parts to be processed located in the frame 3.

[0050] A circulating gas supply mechanism is located inside the housing 1 and above the frame 3. The circulating gas supply mechanism can move along the length of the housing 1 inside the housing 1 to pump carbon dioxide gas to the prefabricated part to be processed.

[0051] An elastic limiting mechanism is provided on each of the two horizontal axes 2. The elastic limiting mechanism is triggered during the movement of the circulating air supply mechanism along the length direction of the box 1, and can move from the side of the frame 3 to above the precast component, and then perform a clamping action on the precast component.

[0052] Please refer to it again. Figure 6 The supporting mechanism includes multiple deflection structures installed on the frame 3. The deflection structure includes a first drive motor 4 installed on the side of the frame 3 and a support plate 5 disposed at the end of the output shaft of the first drive motor 4. The frame 3 is also provided with an opening 301 for the support plate 5 to move.

[0053] Specifically, as shown in the attached drawings, multiple sets of the deflection structures are respectively located at the four corners of the frame 3 to achieve multi-point support for the prefabricated parts and ensure the stability of the prefabricated parts placed on the frame 3. During operation, in the support mechanism with a lower height, the support plate 5 is kept perpendicular to the length direction of the frame 3, while in the support mechanism with a higher height, the support plate 5 is kept parallel to the length direction of the frame 3.

[0054] Furthermore, whenever the circulating air supply mechanism moves to the end position of the housing 1, the elastic limiting mechanism completes the clamping action of the prefabricated part. Then, the first drive motor 4 drives the support plate 5 to deflect 90° so that the states of the two sets of support mechanisms are exchanged. Finally, the second drive motor 6 drives the horizontal shaft 2 to rotate half a turn so that the frame 3 and the prefabricated part inside it can be flipped over.

[0055] Please refer to it again. Figure 4 , Figure 9 , Figure 10 as well as Figure 11 The circulating gas supply mechanism includes two transverse plates 9 symmetrically and movably disposed within the housing 1. The two transverse plates 9 are connected to two sets of threaded drive assemblies disposed within the housing 1. The transverse plates 9 are provided with a gas guiding structure.

[0056] The gas guiding structure includes an inclined plate 7 rotatably mounted on the transverse plate 9, multiple conduits 33 disposed on the transverse plate 9, and a flat nozzle 10 connected to the conduits 33 and located on the side of the inclined plate 7. Multiple air passages 8 are also equidistantly arranged on the side of the inclined plate 7 facing the flat nozzle 10. The rotation shaft of the inclined plate 7 is connected to a deflection control structure, which is triggered when the transverse plate 9 moves to the end of its stroke, causing the inclined plate 7 to perform a deflection action.

[0057] Furthermore, the threaded drive assembly includes a bidirectional lead screw 32 rotatably mounted inside the housing 1 and a third drive motor 31 mounted on the side of the housing 1. One end of the bidirectional lead screw 32 is connected to the output end of the third drive motor 31. The bidirectional lead screw 32 passes through two transverse plates 9, and the two transverse plates 9 are threadedly connected to the bidirectional lead screw 32.

[0058] During operation, the third drive motor 31 drives the bidirectional lead screw 32 to rotate in both the forward and reverse directions. As a result, the two transverse plates 9 simultaneously engage with the bidirectional lead screw 32 through threads, and the two transverse plates 9 move away from and towards each other. Correspondingly, the transverse plates 9 can drive the inclined plate 7 to move together. At the same time, the external pump blows carbon dioxide gas through the conduit 33 and the flat nozzle 10 towards the inclined plate 7. Furthermore, the carbon dioxide gas can be blown towards the precast component through multiple ventilation pipes 8.

[0059] Since the conduit 33 moves linearly during operation, a flexible hose should be connected between the conduit 33 and the air outlet of the external pump.

[0060] During the curing of precast components, the air inlet of the external pump is connected to the housing 1, and the air outlet is connected to the conduit 33 through the telescopic hose. Carbon dioxide gas is blown onto the inclined plate 7 through the flat nozzle 10. The carbon dioxide gas is divided by multiple ventilation pipes 8, which makes the distribution of carbon dioxide gas more uniform and realizes the circulation of carbon dioxide gas in the housing 1. At the same time, in conjunction with the frame 3 to drive the precast components to rotate, it can effectively improve the sufficiency of the mineralization reaction between carbon dioxide gas and alkaline components such as calcium and magnesium in concrete, and ensure the effect of curing treatment of precast concrete components.

[0061] The deflection control structure includes a fixed round rod 11 fixedly installed inside the housing 1 and two driven tubes 12 rotatably installed on the two transverse plates 9 respectively. The two driven tubes 12 are slidably fitted with the fixed round rod 11, and the driven tubes 12 are connected to the rotation shaft of the inclined plate 7 through a bevel gear set 13 and a transmission belt 14.

[0062] In detail, the bevel gear set 13 includes a first bevel gear fixedly mounted on the driven tube 12 and a second bevel gear rotatably mounted on the transverse plate 9. The second bevel gear meshes with the first bevel gear, and the transmission belt 14 is used to connect the rotation shafts of the second bevel gear and the inclined plate 7.

[0063] The outer wall of the fixed round rod 11 is provided with a groove, and the inner wall of the driven tube 12 is provided with a protrusion adapted to the groove. The protrusion extends into the groove and is slidably connected to the fixed round rod 11. The groove includes a first sliding groove 1101 and a second sliding groove 1102 connected to each other. The first sliding groove 1101 is arranged along the axial direction of the fixed round rod 11, and the second sliding groove 1102 is arranged spirally on the fixed round rod 11.

[0064] The third drive motor 31 drives the bidirectional lead screw 32 to rotate, so that when the two transverse plates 9 move away from each other, the two driven tubes 12 slide away from each other on the fixed round rod 11. Correspondingly, the protrusion passes through the first slide groove 1101 and the second slide groove 1102 in sequence. Since the first slide groove 1101 is arranged along the axial direction of the fixed round rod 11, the driven tube 12 does not rotate when the protrusion passes through the first slide groove 1101. However, the second slide groove 1102 is arranged along the spiral direction, so the driven tube 12 will rotate when the protrusion passes through the second slide groove 1102. Then, the driven tube 12 drives the inclined plate 7 to rotate through the bevel gear set 13 and the transmission belt 14. The inclined plate 7 deflects from the inclined state to the horizontal state. Subsequently, the second drive motor 6 drives the frame 3 to rotate half a revolution through the transverse shaft 2, causing the prefabricated part to flip over.

[0065] Therefore, before the precast component is flipped over, the sliding engagement between the protruding post and the second sliding groove 1102 allows the inclined plate 7 to switch from an inclined state to a horizontal state, automatically providing space for the frame 3 to flip over. This achieves the effect of saving space occupied by the device, making the internal structure of the device more compact, and also facilitating the faster distribution of carbon dioxide gas in the box 1.

[0066] Please refer to it again. Figures 5-11The elastic limiting mechanism includes a first sleeve 21 and a second sleeve 22 slidably sleeved on the horizontal shaft 2. A strip-shaped protrusion 201 is formed on the horizontal shaft 2. The inner walls of both the first sleeve 21 and the second sleeve 22 are provided with strip-shaped grooves adapted to the strip-shaped protrusion 201. A first cylindrical spring 23 is also sleeved on the outer periphery of the horizontal shaft 2. The two ends of the first cylindrical spring 23 are respectively connected to the first sleeve 21 and the second sleeve 22. The second sleeve 22 is provided with two sets of elastic pressure components. The first sleeve 21 is connected to a booster component located inside the housing 1. The booster component cooperates with the transverse plate 9. The booster assembly includes an L-shaped guide rail 18 disposed on the inner wall of the housing 1, and a first slider 19 and a second slider 20 slidably fitted on the guide rail 18. The second slider 20 is rotatably connected to the first sleeve 21 via a fixed arm 2001. Two sets of sliding clearance structures are provided between the first slider 19 and the transverse plate 9. A connecting rod 15 is also provided between the first slider 19 and the second slider 20, and the two ends of the connecting rod 15 are respectively hinged to the first slider 19 and the second slider 20. The sliding clearance structure includes a follower plate 16 fixed to the first slider 19 via a connecting arm 17 and a column 901 fixed at the end of the transverse plate 9. The follower plate 16 is provided with a guide groove adapted to the column 901. The column 901 passes through the guide groove and is slidably connected to the follower plate 16. The guide groove includes a first through groove 1601 and a second through groove 1602 connected together. The first through groove 1601 is arranged along the length direction of the follower plate 16, and the second through groove 1602 is inclined.

[0067] During the movement of the two transverse plates 9 away from each other within the housing 1, the column 901 will pass through the first through groove 1601 and the second through groove 1602 in sequence. When the column 901 moves along the first through groove 1601, the follower plate 16 does not move. However, when it moves along the second through groove 1602, it will slide with the follower plate 16. Then, the follower plate 16 will drive the first slider 19 to slide downward on the guide rail 18 through the connecting arm 17. At the same time, the first slider 19 will push the second slider 20 to slide away from the inner wall of the housing 1 on the guide rail 18 through the connecting rod 15. This will cause the second slider 20 to drive the first sleeve 21 to slide close to the frame 3 on the transverse axis 2 through the fixed arm 2001. The first sleeve 21 will then drive the second sleeve 22 to slide together through the first columnar spring 23, so that the elastic pressure assembly moves above the preform, making it easier for the elastic pressure assembly to clamp the preform.

[0068] The elastic pressure assembly includes a guide plate 24 disposed on the second sleeve 22 and a driven plate 25 slidably fitted with the guide plate 24. A transmission plate 30 is fixed on the driven plate 25. Two fastening rods 29 are fixed on the first sleeve 21. A gap adapted to the transmission plate 30 is reserved between the two fastening rods 29. A drive column is fixedly disposed in the gap. An inclined groove 3001 adapted to the drive column is provided on the transmission plate 30. The drive column passes through the inclined groove 3001 and is slidably connected to the transmission plate 30. Two connecting columns 26 are also slidably disposed on the driven plate 25. A pressure plate 28 is fixedly connected to one end of the two connecting columns 26 facing the horizontal axis 2. A second columnar spring 27 is sleeved on the outer periphery of the connecting columns 26. The two ends of the second columnar spring 27 are respectively connected to the driven plate 25 and the pressure plate 28.

[0069] During the initial stroke of the first sleeve 21 sliding towards the frame 3, the first sleeve 21 drives the second sleeve 22 to slide towards the frame 3 on the horizontal axis 2 via the first cylindrical spring 23, causing the pressure plate 28 to move above the preform. After the second sleeve 22 abuts against the side of the frame 3, as the first sleeve 21 continues to slide, the first cylindrical spring 23 gradually compresses, and correspondingly, the distance between the first sleeve 21 and the second sleeve 22 shortens. The drive column connects to the transmission plate via the inclined groove 3001. The transmission plate 30 slides in a sliding engagement, causing the driven plate 25 to slide on the guide plate 24 toward the inside of the guide plate 24. Correspondingly, the pressure plate 28 moves closer to the surface of the preform until the second columnar spring 27 is compressed. After the preform is flexibly clamped, the second drive motor 6 drives the frame 3 to flip the preform through the horizontal shaft 2. At this time, the horizontal shaft 2 drives the first sleeve 21 and the second sleeve 22 to rotate synchronously through the strip-shaped protrusion 201, ensuring the stability of the pressure plate 28 in clamping the preform.

[0070] As another embodiment of the present invention, a carbon dioxide gas-solid mineralization curing process for precast concrete components is also proposed, which uses the aforementioned apparatus and includes the following steps:

[0071] Step 1: Place the precast component to be processed inside the frame 3, support the precast component with the supporting mechanism, seal the box 1, and inject carbon dioxide gas.

[0072] Step 2: The external pump operates, and the circulating gas supply mechanism moves along the length of the housing 1 inside the housing 1, circulating and pumping the carbon dioxide gas in the housing 1.

[0073] Step 3: The deflection control structure and the elastic limiting mechanism are triggered. The elastic limiting mechanism moves above the precast part and performs a clamping action on the precast part. The deflection control structure switches the tilting state of the tilting plate 7 to the horizontal state.

[0074] Step 4: Frame 3 drives the prefabricated component to flip over, and the circulating gas supply mechanism continues to circulate carbon dioxide gas.
