Description

Technical Field

[0001] This disclosure relates to the field of mineralization curing equipment technology, specifically to a CO2 mineralization curing equipment and its safety device. Background Technology

[0002] Currently, CO2 mineralization curing technology is mainly applied in the concrete production process. The core of this technology is to inject CO2 from industrial waste gas into fresh concrete through a special method, so that it reacts chemically with the calcium and magnesium components in the concrete, permanently solidifying the CO2 in the concrete, and then curing it through a CO2 mineralization curing device to accelerate the hardening speed of the concrete.

[0003] In related technologies, CO2 mineralization curing devices are pressurized gaseous CO2 reaction vessels. They are equipped with breather valves and pressure relief devices according to relevant safety regulations for pressure vessels to ensure their safety. Because the CO2 mineralization curing device contains CO2, a large amount of CO2 will be released when the breather valve is activated. This will cause the CO2 concentration in the surrounding environment to rise rapidly, potentially posing a significant safety hazard to on-site operators and inspectors. Summary of the Invention

[0004] The purpose of this disclosure is to provide a CO2 mineralization curing device and its safety device to solve the technical problems existing in the related art.

[0005] To achieve the above objectives, this disclosure provides a safety device for a CO2 mineralization curing apparatus, comprising:

[0006] The breathing valve body has an internal cavity and is positioned above the CO2 mineralization curing device. The breathing valve body has a first connecting port, a second connecting port, and a third connecting port that communicate with the cavity. The first connecting port connects the cavity to the interior of the CO2 mineralization curing device. The second and third connecting ports connect the cavity to the outside. The second connecting port allows external gas to be drawn into the cavity, and the third connecting port allows gas to be discharged from the cavity to the outside.

[0007] A CO2 concentration detector is installed inside the containment cavity and used to detect the CO2 content within the containment cavity; and

[0008] The fresh air system includes a control unit and a ventilation component. The control unit can control the ventilation component to introduce fresh air into the containment cavity based on the signal monitored by the CO2 concentration detector, so as to dilute the CO2 concentration in the containment cavity.

[0009] Optionally, the ventilation assembly includes a ventilation duct, one end of which is connected to the receiving cavity, and the other end of which is used to introduce fresh air.

[0010] Optionally, the first connecting port and the second connecting port are arranged side by side in the horizontal direction;

[0011] The safety device also includes:

[0012] A lifting assembly, disposed within the receiving cavity, is used to adjust the vertical height of the CO2 concentration detector, allowing the CO2 concentration detector to move closer to or further away from the second communication port; and

[0013] The fan is rotatably disposed in the first communication port in the vertical direction, and can rotate unidirectionally in the vertical direction when the gas passes through the first communication port from top to bottom, and remains stationary when the gas passes through the first flow port from bottom to top;

[0014] The fan is connected to the lifting assembly via a first transmission component, so that when the fan rotates unidirectionally in the vertical direction within the first connection port, the lifting assembly can drive the CO2 concentration detector away from the second connection port.

[0015] Optionally, the lifting assembly includes a threaded rod, a guide rod, and a lifting plate. The threaded rod extends vertically and is axially locked and rotatably mounted on the inner wall of the receiving cavity. The threaded rod is connected to the fan via the first transmission assembly. The guide rod is mounted on the inner wall of the receiving cavity and is parallel to the threaded rod.

[0016] The lifting plate has a first threaded hole and a guide hole. The lifting plate is threadedly connected to the threaded rod through the first threaded hole and slidably connected to the guide rod through the guide hole, so that the lifting plate can move in the vertical direction. The CO2 concentration detector is installed on the lifting plate.

[0017] The lifting plate includes a first part and a second part. The first part and the second part are slidably connected in the horizontal direction so that the first part can move closer to or further away from the second part in the horizontal direction. The second part is slidably connected to the guide rod. An electromagnet is provided on the first part, and the second part is magnetic.

[0018] When the electromagnet is energized, it magnetically attracts the second part, and the first part abuts against the second part to form the first threaded hole, so that the lifting plate is threadedly connected to the threaded rod through the first threaded hole. When the electromagnet is de-energized, the first part disengages from the second part, so that the lifting plate is disengaged from the threaded rod.

[0019] Optionally, the safety device further includes a filter plate with multiple filter holes, the filter plate being rotatably disposed in the second communication port about a vertical direction, and the filter plate being connected to the threaded rod via a second transmission assembly.

[0020] Optionally, the first transmission assembly includes a driving wheel, a driven wheel, and an annular transmission member. The rotating shaft of the fan is coaxially connected to the driving wheel, the driven wheel is coaxially connected to the threaded rod, and the annular transmission member is wound around the driving wheel and the driven wheel.

[0021] The second transmission assembly includes a gear and a gear ring. The gear is coaxially sleeved on the lower end of the threaded rod, and the gear ring is coaxially sleeved on the outside of the filter plate. The gear and the gear ring mesh with each other.

[0022] Optionally, the safety device further includes a diversion grid disposed above and parallel to the filter plate.

[0023] Optionally, the safety device further includes a cleaning brush and a fixing element;

[0024] The cleaning brush extends horizontally and is detachably mounted below the filter plate via the fixing member, and can abut against the lower surface of the filter plate.

[0025] The fastener includes a fastening bolt, the cleaning brush has a through hole formed in the vertical direction, and the breathing valve body has a second threaded hole extending in the vertical direction. The fastening bolt is used to pass through the aligned through hole and the second threaded hole, and the fastening bolt is threadedly engaged with the second threaded hole to connect the cleaning brush to the breathing valve body.

[0026] Optionally, the fastener further includes a connecting rod, one end of which is connected to the fastening bolt, and a first baffle is provided at the end of the connecting rod away from the fastening bolt;

[0027] A receiving groove is formed in the through hole for accommodating the fastening bolt. One end of the fastening bolt connected to the connecting rod is located in the receiving groove and is provided with a second baffle. The second baffle can move in the receiving groove along the axial direction of the fastening bolt and can abut against the end wall of the receiving groove.

[0028] The fastening bolt is fitted with an elastic element inside the receiving groove. One end of the elastic element abuts against the inner wall of the receiving groove, and the other end abuts against the second baffle. The elastic element can apply an elastic force to the fastening bolt in the vertical direction so that the fastening bolt can be located in the receiving groove when it is in a free state.

[0029] According to a second aspect of this disclosure, a CO2 mineralization curing device is provided, including a CO2 mineralization curing device body and a safety device for the aforementioned CO2 mineralization curing device.

[0030] Through the above technical solution, when the air pressure inside the CO2 mineralization curing device increases, CO2 inside the device will enter the receiving cavity inside the breathing valve body through the first connecting port. The CO2 content in the receiving cavity will increase. The CO2 concentration detector can detect the CO2 content in the receiving cavity and feed back the detected CO2 signal to the control unit. The control unit can control the ventilation component to introduce fresh air into the receiving cavity to dilute the CO2 concentration in the receiving cavity. This reduces the concentration of CO2 emitted by the pressure relief valve of the breathing valve body, which is pushed open as the air pressure in the receiving cavity increases. This reduces the safety hazards caused by the rapid increase of CO2 content in the vicinity of the CO2 mineralization curing device and improves the safety of the CO2 mineralization curing device.

[0031] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0043] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0044] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" are used to indicate orientation or positional relationship based on the drawing orientation shown in the accompanying drawings. They are used only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientation construction and operation. Therefore, they should not be construed as limitations on this disclosure. The terms "inner" and "outer" refer to the inner and outer contours of the corresponding structures, and "first" and "second" are used to distinguish one element from another.

[0045] like Figures 1-8 As shown, this disclosure provides a safety device for a CO2 mineralization curing apparatus. The safety device includes a breather valve body 1, a CO2 concentration detector 6, and a fresh air system 7. The breather valve body 1 has an internal cavity 2, which is positioned above the CO2 mineralization curing apparatus. The breather valve body 1 has a first connecting port 3, a second connecting port 4, and a third connecting port 5, all communicating with the cavity 2. The first connecting port 3 connects the cavity 2 to the interior of the CO2 mineralization curing apparatus. The second connecting port 4 and the third connecting port 5 both connect the cavity 2 to the outside environment. The second connecting port 4 allows outside gas to be drawn into the cavity 2, and the third connecting port 5 allows gas to be discharged from the cavity 2 to the outside environment. The CO2 concentration detector 6 is positioned inside the cavity 2 and is used to detect the CO2 content within the cavity 2. The fresh air system 7 includes a control unit and a ventilation assembly. The control unit controls the ventilation assembly to introduce fresh air into the cavity 2 based on the signal monitored by the CO2 concentration detector 6, thereby diluting the CO2 concentration in the cavity 2.

[0046] Through the above technical solution, when the air pressure inside the CO2 mineralization curing device increases, CO2 inside the CO2 mineralization curing device will enter the receiving cavity 2 inside the breathing valve body 1 through the first connecting port 3. The CO2 content in the receiving cavity 2 will increase. The CO2 concentration detector 6 can detect the CO2 content in the receiving cavity 2 and feed back the detected CO2 signal to the control unit. The control unit can control the ventilation component to introduce fresh air into the receiving cavity 2 to dilute the CO2 concentration in the receiving cavity 2. This reduces the concentration of CO2 emitted by the pressure relief valve of the breathing valve body 1, which is pushed open as the air pressure inside the receiving cavity 2 increases. This reduces the safety hazards caused by the rapid increase in CO2 content in the vicinity of the CO2 mineralization curing device and improves the safety of the CO2 mineralization curing device.

[0047] Understandably, in some implementations, the control unit may be a controller that can receive the signal detected by the CO2 concentration detector 6 and can start or stop the ventilation assembly from introducing fresh air into the accommodating cavity 2.

[0048] Here, the breathing valve body 1 includes a negative pressure valve and a pressure relief valve. The negative pressure valve can be located in the second connecting port 4, used to cut off or open the second connecting port 4 to cut off or open the receiving cavity 2 to the outside. The negative pressure valve only opens when the pressure inside the receiving cavity 2 decreases. The pressure relief valve can be located in the third connecting port 5, used to cut off or open the third connecting port 5 to cut off or open the receiving cavity 2 to the outside. The pressure relief valve only opens when the pressure inside the receiving cavity 2 increases. When the pressure inside the receiving cavity 2 decreases, the external atmospheric pressure can open the negative pressure valve, allowing gas to be supplied to the receiving cavity 2 through the second connecting port 4 to balance the pressure inside the CO2 mineralization curing device. During this process, the pressure relief valve does not open. When the pressure inside the receiving cavity 2 increases, the gas pressure inside the receiving cavity 2 can open the pressure relief valve, allowing gas to be discharged to the outside through the third connecting port 5 to reduce the pressure inside the CO2 mineralization curing device. During this process, the negative pressure valve does not open.

[0049] Optionally, the ventilation assembly includes a ventilation duct 701, one end of which is connected to the receiving cavity 2, and the other end of which is used to introduce fresh air. Fresh air is directly introduced into the receiving cavity 2 through the ventilation duct 701 to dilute the CO2 concentration within the receiving cavity 2. In some embodiments, a blower can be used to introduce fresh air into the receiving cavity 2, and a CO2 adsorption device can be installed inside the ventilation duct 701 to reduce the amount of external CO2 entering the receiving cavity 2.

[0050] Optionally, such as Figure 5 As shown, the first connecting port 3 and the second connecting port 4 are arranged side by side in a horizontal direction. The safety device also includes a lifting assembly 8 and a fan 9. The lifting assembly 8 is disposed within the receiving cavity 2 and is used to adjust the vertical height of the CO2 concentration detector 6, allowing it to move closer to or further away from the second connecting port 4. The fan 9 is rotatably disposed within the first connecting port 3 in a vertical direction, and can rotate unidirectionally in a vertical direction when gas passes through the first connecting port 3 from top to bottom, remaining stationary when gas passes through the first flow port from bottom to top. The fan 9 is connected to the lifting assembly 8 via a first transmission assembly 10, so that during the unidirectional rotation of the fan 9 within the first connecting port 3 in a vertical direction, the lifting assembly 8 can drive the CO2 concentration detector 6 away from the second connecting port 4.

[0051] Here, the initial position of the CO2 concentration detector 6 can be set near the first connecting port 3. According to this setting, the fan 9 remains stationary as gas flows upward through the first connecting port. That is, when the pressure inside the CO2 mineralization curing device increases and needs to be released into the receiving cavity 2, the gas inside the CO2 mineralization curing device can enter the receiving cavity 2 from bottom to top through the first connecting port 3. During this process, the fan 9 can remain stationary. Furthermore, the gas entering the receiving cavity 2 from the CO2 mineralization curing device may contain a large amount of CO2. The CO2 concentration detector 6 detects the CO2 content in the receiving cavity 2 and feeds the detected CO2 signal back to the control unit. The control unit can then control the ventilation assembly to introduce fresh air into the receiving cavity 2 to dilute the CO2 concentration. Additionally, since the CO2 concentration detector 6 is located near the first connecting port 3 during this process, it can detect the CO2 concentration near the first connecting port 3, thus improving the detection accuracy of the CO2 concentration detector 6.

[0052] As gas flows downwards through the first connecting port 3, the fan 9 can rotate unidirectionally in the vertical direction. That is, when the pressure inside the CO2 mineralization curing device decreases, and the containing chamber 2 needs to draw in gas from the outside to balance the pressure inside the CO2 mineralization curing device, the outside gas enters the containing chamber 2 through the second connecting port 4. The gas inside the containing chamber 2 can then enter the CO2 mineralization curing device from top to bottom through the first connecting port 3. During this process, the fan 9 can rotate unidirectionally in the vertical direction, and the fan 9 can be driven by the first transmission component 10. The lifting component 8 can then move the CO2 concentration detector 6 away from the second connecting port 4, allowing the CO2 concentration detector 6 to rise to the highest point inside the containing chamber 2 and be as far away from the second connecting port 4 as possible. Since the gas entering the containing chamber 2 from the outside also contains CO2, although the CO2 content is low, the CO2 concentration detector 6 has a relatively large detection range and can detect even low concentrations of CO2. As the position of the CO2 concentration detector 6 rises and moves as far away from the second connection port 4 as possible, the contact between the CO2 concentration detector 6 and the CO2 inhaled into the outside air in the containment cavity 2 is reduced as the outside air passes through the second connection port 4, the containment cavity 2 and the first connection port 3 in sequence. This can prevent the CO2 concentration detector 6 from making false judgments and thus prevent the ventilation assembly from introducing fresh air into the containment cavity 2.

[0053] Optionally, combined Figure 2 and Figure 3The lifting assembly 8 includes a threaded rod 801, a guide rod 802, and a lifting plate 803. The threaded rod 801 extends vertically and is axially locked and rotatably mounted on the inner wall of the receiving cavity 2. The threaded rod 801 is connected to the fan 9 via a first transmission assembly 10. The guide rod 802 is mounted on the inner wall of the receiving cavity 2 and parallel to the threaded rod 801. The lifting plate 803 has a first threaded hole 11 and a guide hole 12. The lifting plate 803 is threadedly connected to the threaded rod 801 through the first threaded hole 11 and slidably connected to the guide rod 802 through the guide hole 12, so that the lifting plate 803 can move vertically. The CO2 concentration detector 6 is mounted on the lifting plate 803. With this configuration, as the fan 9 rotates unidirectionally in the vertical direction, the fan 9 also drives the threaded rod 801 to rotate through the first transmission component 10, so that the lifting plate 803 can move upward in the vertical direction under the limiting action of the guide rod 802, thereby facilitating the movement of the CO2 concentration detector 6 away from the second communication port 4.

[0054] Optionally, such as Figure 4 As shown, the lifting plate 803 includes a first part 8031 ​​and a second part 8032. The first part 8031 ​​and the second part 8032 are slidably connected in the horizontal direction, allowing the first part 8031 ​​to move closer to or further away from the second part 8032 in the horizontal direction. The second part 8032 is slidably connected to the guide rod 802. An electromagnet is provided on the first part 8031, and the second part 8032 is magnetic. Here, the electromagnet can be directly the first part 8031, or the electromagnet can be disposed on the first part 8031. When the electromagnet is energized, it magnetically attracts the second part 8032. The first part 8031 ​​and the second part 8032 abut against each other and form a first threaded hole 11, so that the lifting plate 803 is threadedly connected to the threaded rod 801 through the first threaded hole 11. When the electromagnet is de-energized, the first part 8031 ​​and the second part 8032 disengage, so that the lifting plate 803 is disengaged from the threaded rod 801. In other words, when the electromagnet is energized, the lifting plate 803 is threadedly connected to the threaded rod 801; when the electromagnet is de-energized, the lifting plate 803 is not connected to the threaded rod 801, and the lifting plate 803 is only slidably connected to the guide rod 802 through the guide hole 12.

[0055] In some implementations, such as Figure 4 As shown, two horizontally extending slide rods 26 can be arranged side by side on the second part 8032. A sliding hole is provided in the first part 8031. The slide rods 26 can be slidably connected to the first part 8031 ​​through the sliding hole to realize the movement of the first part 8031 ​​and the second part 8032 towards each other or away from each other.

[0056] In other embodiments, the safety device of the CO2 mineralization maintenance apparatus may also include a control system and a pressure sensor, with the pressure sensor located inside the second connection port 4. When air enters the second connection port 4, the pressure sensor detects a pressure signal and transmits it to the control system. The control system energizes the electromagnet, causing the first part 8031 ​​and the second part 8032 to magnetically attract each other. The lifting plate 803 is threadedly connected to the threaded rod 801, allowing the lifting plate 803 to rise vertically during the rotation of the fan 9. When air enters the second connection port 4 and stops, the pressure sensor does not detect a pressure signal. The control system de-energizes the electromagnet, causing the first part 8031 ​​and the second part 8032 to disengage. The lifting plate 803 descends vertically under its own weight and the weight of the CO2 concentration detector 6, returning to the initial position of the CO2 concentration detector 6, which is close to the first connection port 3.

[0057] In this disclosure, it is understood that when gas passes through the first connecting port 3 from top to bottom, the rotation direction of the fan 9 can be set to clockwise. That is, the fan 9 can drive the threaded rod 801 to rotate clockwise through the first transmission assembly 10, and can drive the CO2 concentration detector 6 vertically to the upper end of the threaded rod 801 so that it can abut against the inner wall of the receiving cavity 2. Alternatively, a stop plate can be provided at the upper end of the threaded rod 801 so that the CO2 concentration detector 6 can abut against the stop plate, thereby stopping it. The rising motion stops the CO2 concentration detector 6, allowing it to move as far away from the second connection port 4 as possible and stop the fan 9 from rotating. When the gas stops flowing from top to bottom through the first connection port 3 or when the gas flows from bottom to top through the first connection port 3, the lifting plate 803 disengages from the threaded rod 801. The lifting plate 803 can then descend vertically under its own weight and the weight of the CO2 concentration detector 6, returning to the initial position of the CO2 concentration detector 6, allowing the CO2 concentration detector 6 to move as close as possible to the second connection port 4.

[0058] Optionally, such as Figure 2 As shown, the safety device also includes a filter plate 13 with multiple filter holes 14. The filter plate 13 is rotatably disposed within the second communication port 4 in a vertical direction. The filter plate 13 is connected to the threaded rod 801 via a second transmission assembly 15. The filter plate 13 can filter the gas entering the receiving cavity 2 from the outside, and the rotating filter plate 13 can improve the filtration effect of the gas.

[0059] Optionally, such as Figure 5As shown, the first transmission assembly 10 includes a driving wheel 1001, a driven wheel 1002, and an annular transmission member 1003. The rotating shaft of the fan 9 is coaxially connected to the driving wheel 1001, and the driven wheel 1002 is coaxially connected to the threaded rod 801. The annular transmission member 1003 is wound around the driving wheel 1001 and the driven wheel 1002. Thus, during the rotation of the fan 9, the rotating shaft of the fan 9 drives the driving wheel 1001 to rotate, and the driving wheel 1001 drives the driven wheel 1002 to rotate through the annular transmission member 1003, thereby facilitating the rotation of the threaded rod 801. In some embodiments, the annular transmission member 1003 can be an annular belt or an annular chain. When the annular transmission member 1003 is an annular chain, both the driving wheel 1001 and the driven wheel 1002 are sprockets.

[0060] To facilitate the rotation of the filter plate 13, the second transmission assembly 15 optionally includes a gear 1501 and a gear ring 1502. The gear 1501 is coaxially sleeved on the lower end of the threaded rod 801, and the gear ring 1502 is coaxially sleeved on the outside of the filter plate 13. The gear 1501 and the gear ring 1502 mesh. Thus, during the rotation of the threaded rod 801, the gear 1501 rotates together with the threaded rod 801, and through the meshing of the gear 1501 and the gear ring 1502, the gear ring 1502 is easily driven to rotate, thereby causing the filter plate 13 to rotate.

[0061] Optionally, the safety device also includes a diversion grille 16, which is disposed above and parallel to the filter plate 13, so that the diversion grille 16 can divert the gas entering through the second connection port 4 into multiple airflows and decelerate the gas, thereby reducing the noise caused by the excessively fast gas flow rate during the process of the airflow passing through the second connection port 4.

[0062] To facilitate cleaning of the filter plate 13, the safety device may optionally include a cleaning brush 17 and a fixing member 18. The cleaning brush 17 extends horizontally and is detachably mounted below the filter plate 13 via the fixing member 18, and can abut against the lower surface of the filter plate 13. With this configuration, the cleaning brush 17 abuts against the lower surface of the filter plate 13, and can clean the filter plate 13 as it rotates.

[0063] To facilitate the detachment of the cleaning brush 17 from the filter plate 13, the fixing member 18 optionally includes a fastening bolt 1801. The cleaning brush 17 has a through hole 19 extending vertically, and the breather valve body 1 has a second threaded hole 20 extending vertically. The fastening bolt 1801 passes through the aligned through hole 19 and the second threaded hole 20, and the fastening bolt 1801 is threaded into the second threaded hole 20 to connect the cleaning brush 17 to the breather valve body 1. That is, when the filter plate 13 needs to be cleaned, the through hole 19 and the second threaded hole 20 are aligned, and the fastening bolt 1801 is passed through the through hole 19 and the second threaded hole 20 respectively to connect the cleaning brush 17 to the breather valve body 1; when the cleaning brush 17 needs to be cleaned, the fastening bolt 1801 is removed, thereby detaching the cleaning brush 17 from the breather valve body 1, so that the cleaning brush 17 can be replaced or cleaned.

[0064] Optionally, combined Figure 5 and Figure 6 The fastener 18 also includes a connecting rod 1802, one end of which is connected to the fastening bolt 1801. A first baffle 21 is provided at the end of the connecting rod 1802 away from the fastening bolt 1801. A receiving groove 22 is formed within the through hole 19 for accommodating the fastening bolt 1801. The end of the fastening bolt 1801 connected to the connecting rod 1802 is located within the receiving groove 22 and is provided with a second baffle 23. The second baffle 23 can move within the receiving groove 22 along the axial direction of the fastening bolt 1801 and can abut against the end wall of the receiving groove 22. An elastic element 24 is fitted inside the receiving groove 22 on the fastening bolt 1801. One end of the elastic element 24 abuts against the inner wall of the receiving groove 22, and the other end abuts against the second baffle 23. The elastic element 24 can apply an elastic force to the fastening bolt 1801 in the vertical direction so that the fastening bolt 1801 can be located within the receiving groove 22 in its free state. With this configuration, after the cleaning brush 17 is disassembled, the fastening bolt 1801 is in a free state. The elastic element 24 applies an elastic force to the second baffle 23, allowing the fastening bolt 1801 to enter the receiving groove 22. Under the continuous contact of the elastic element 24, the fastening bolt 1801 remains within the receiving groove 22, thus preventing damage to the threads of the fastening bolt 1801 when the cleaning brush 17 is not in use. In some embodiments, the elastic element 24 can be a spring.

[0065] According to a second aspect of this disclosure, a CO2 mineralization curing device is provided, including a CO2 mineralization curing device body 25 and the aforementioned safety device for the CO2 mineralization curing device.
