Description

Technical Field

[0001] This invention relates to the field of concrete mixing technology, specifically to a dynamic carbon fixation intelligent equipment for cement-based recycled micro-powder concrete. Background Technology

[0002] With the increasing demand from the construction industry for the resource utilization and carbon sequestration of waste concrete, waste concrete mixing equipment has become a core piece of equipment for the preparation of recycled aggregates. Traditional mixing equipment generally suffers from problems such as low discharge efficiency, severe adhesion to the barrel walls, and difficulty in cleaning: On the one hand, the fixed discharge port limits the material discharge speed, and residual material after mixing is prone to accumulate and dry, adhering to the barrel walls to form hard lumps, which not only reduces the single discharge volume but also increases the cost of equipment cleaning and maintenance; on the other hand, the deposits on the barrel walls interfere with the uniformity of subsequent mixing, affecting the carbon sequestration effect of recycled aggregates and the quality of finished products, while frequent manual cleaning leads to low production efficiency and increased energy consumption.

[0003] To this end, Chinese Patent No. CN117162277B discloses a waste concrete mixing device for enhanced carbon sequestration. The device can rotate the fixing frame, mixing module and discharge module by 90° using a flipping module. By opening the diffusion discharge component, the discharge port can be expanded. The air pressurization component sprays high-pressure gas towards one side of the diffusion discharge component, which accelerates the discharge of materials in the mixing drum. At the same time as the air pressurization component sprays high-pressure gas, the mixing rod rotates synchronously. Through the centrifugal force of the rotating mixing rod, the high-pressure gas sprayed by the air pressurization component is in a rotating state, which can achieve the cleaning of the inner wall of the mixing drum by high-pressure gas and effectively prevent concrete from adhering to the inner wall of the mixing drum.

[0004] High-pressure gas relies solely on the centrifugal force of the stirring rod to form a rotating airflow. The airflow distribution is uneven, and the impact force on the adhering substances in the bottom, corners and other blind spots of the stirring is insufficient, making it impossible to completely remove stubborn clumps. Furthermore, cleaning relies solely on airflow without the assistance of mechanical scraping, resulting in poor cleaning effect on hardened concrete adhering layers. Summary of the Invention

[0005] To address the aforementioned issues, a dynamic carbon fixation intelligent equipment for cement-based recycled micro-powder concrete is provided. This equipment solves the technical problem that traditional mixing devices, which rely solely on high-pressure airflow to clean the tank wall, lack sufficient impact force on the bottom and corner blind areas of the tank wall, resulting in the inability to remove stubborn clumps.

[0009] Preferably, the cover is provided with a limiting mechanism, which includes a limiting component and a control component; the limiting component is used to limit the rotation of the scraper blade; and the control component is used to release the limiting component from restricting the rotation of the scraper blade.

[0010] Preferably, the limiting component includes a first support, a locking block, and a second elastic element; the first support is disposed on the cover; the locking block is slidably mounted on the first support, and the scraper has a slot that cooperates with the locking block. When the scraper is in a retracted state, the locking block is inserted into the slot under the elastic force of the second elastic element; the two ends of the second elastic element are respectively connected to the first support and the locking block.

[0011] Preferably, the control component includes an extension block, a control rod, and a push block; the extension block is connected to a locking block, and the extension block has an inclined guide groove; the control rod is slidably mounted on a first support; the push block is disposed on the control rod, and as the control rod moves away from the first support, the push block presses against the inclined guide groove, thereby driving the locking block to move closer to the first support.

[0012] Preferably, the control assembly further includes a connecting rod and an abutment block; the connecting rod is connected to the control rod; the abutment block is disposed on the connecting rod and abuts against the inner wall of the tank.

[0013] Preferably, the mounting base is provided with a support seat, which abuts against the scraper when the scraper is in the extended state.

[0014] Preferably, the control mechanism further includes a sealing cover for isolating the third rotary drive assembly.

[0015] Preferably, the support frame is provided with a second support, and the second support is rotatably provided with a roller that is rolledly connected to the outer wall of the tank.

[0016] The advantages of this invention compared to the prior art are:

[0017] 1. This invention, through a processing tank, a mixing mechanism, and a control mechanism, achieves the function of mechanically scraping and cleaning the inner wall of the processing tank during dynamic carbon fixation of cement-based recycled micro-powder concrete. This ensures a thorough carbon fixation reaction and complete removal of adhering substances from the tank wall, solving the technical problem of traditional mixing devices relying solely on high-pressure airflow for tank wall cleaning, which lacks sufficient impact force on the bottom and corner blind areas, resulting in the inability to remove stubborn clumps. By combining agitation and airflow carbon fixation with mechanical scraping, the carbon fixation and cleaning effects are improved, manual maintenance is reduced, and production efficiency is increased.

[0018] 2. This invention achieves the function of controlling the movement of the scraper relative to the inner wall of the tank for cleaning by means of a cover, a tank body, and a second rotary drive assembly. By controlling the rotation of the tank body, the effect of cleaning the inner wall of the tank body by the scraper is achieved. Furthermore, during cleaning, it ensures that impurities are within a specified range, making it convenient for operators to centrally process the cleaned impurities. This solves the technical problem of secondary pollution caused by the difficulty in thoroughly cleaning the scraped impurities.

[0019] 3. This invention achieves the function of driving the scraper to rotate through the mounting base and the third rotary drive assembly, thus achieving the effect of switching the scraper state. After the scraper is switched to the extended state, the second rotary drive assembly on the support frame drives the tank to rotate. The scraper remains stationary because it is fixed to the cover. During the rotation of the tank, the extended scraper continuously adheres to the inner wall of the tank, thoroughly scraping away the material adhering to blind spots such as the bottom and corners of the tank. After cleaning is completed, the third rotary drive assembly drives the rotating shaft to rotate in the opposite direction, causing the scraper to switch back to the retracted state. The second rotary drive assembly stops driving the tank to rotate, and then the carbon fixation operation resumes. The coordinated operation of all structures ensures the cleaning effect of the tank wall, avoids interference with the carbon fixation operation during the cleaning process, reduces equipment maintenance costs, and improves the overall stability and reliability of the operation.

[0031] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figures 1 to 4 A dynamic carbon fixation intelligent device for cement-based recycled micro-powder concrete includes a processing tank 1 and a mixing mechanism 2. The mixing mechanism 2 includes a main shaft 21 rotatably disposed inside the processing tank 1 and a first rotary drive for driving the main shaft 21 to rotate. A mixing rod 211 is sleeved on the main shaft 21, and a nozzle 212 for spraying gas is provided on the mixing rod 211. The processing tank 1 is provided with a scraper 11 for cleaning the inner wall of the processing tank 1. The scraper 11 has a contracted state that fits against the inner wall of the processing tank 1 and an extended state that stands upright along the radial direction of the processing tank 1. The processing tank 1 is provided with a control mechanism 3 for controlling the rotation of the scraper 11 to switch states.

[0033] This invention, through a processing tank 1, a stirring mechanism 2, and a control mechanism 3, achieves the function of mechanically scraping and cleaning the inner wall of the processing tank 1 during dynamic carbon fixation of cement-based recycled micro-powder concrete. This ensures sufficient carbon fixation reaction and thorough cleaning of adhering substances on the tank wall, solving the technical problem of traditional stirring devices relying solely on high-pressure airflow to clean the tank wall, which results in insufficient impact force on the bottom and corner blind areas, leading to the inability to remove stubborn clumps. During operation, the first rotary drive drives the main shaft 21 inside the processing tank 1 to rotate. The main shaft 21 drives the stirring rod 211 to rotate, and the nozzle 212 on the stirring rod 211 sprays gas to stir the cement-based recycled micro-powder concrete inside the tank and achieve dynamic carbon fixation. At this time, the scraper 11 is in a retracted state and does not occupy the stirring space, thus not interfering with the stirring and air-jet carbon fixation operations. During deep cleaning, the scraper 11 is rotated by the control mechanism 3 inside the treatment tank 1, so that the scraper 11 switches to an extended state that stands upright along the radial direction of the treatment tank 1. When the scraper 11 is in the extended state, it can directly contact and scrape off the adhering material on the inner wall of the treatment tank 1, and achieve mechanical cleaning of the blind areas and stubborn clumps on the tank wall. By combining agitation and air jet carbon fixation with mechanical wall scraping, the carbon fixation effect and cleaning effect are improved, manual maintenance is reduced, and production efficiency is increased.

[0034] Reference Figures 1 to 4 The processing tank 1 includes a cover 12 and a tank body 13. There are two covers 12. The two ends of the tank body 13 are rotatably connected to the two covers 12 respectively. A support frame 121 is connected to the cover 12. The two ends of the scraper 11 are respectively disposed on the two covers 12. The support frame 121 is provided with a second rotary drive assembly 14 for driving the tank body 13 to rotate. When the scraper 11 switches to the extended state, the second rotary drive assembly 14 drives the tank body 13 to rotate to perform cleaning work.

[0035] The present invention realizes the function of controlling the movement of the scraper 11 relative to the inner wall of the tank 13 to perform cleaning work through the cover 12, the tank 13, and the second rotation drive assembly 14. By controlling the rotation of the tank 13, the effect of cleaning the inner wall of the tank 13 by the scraper 11 is achieved. Moreover, during cleaning, it can ensure that the impurities are within a specified range, which makes it convenient for operators to centrally process the cleaned impurities. This solves the technical problem that the scraped impurities are difficult to clean thoroughly, resulting in secondary pollution. During operation, the processing tank 1 consists of two covers 12 and a tank body 13. The two ends of the tank body 13 are rotatably connected to the two covers 12, and the covers 12 are connected to the support frame 121. The two ends of the scraper 11 are respectively set on the two covers 12. When it is necessary to clean the inner wall of the processing tank 1, the control mechanism 3 controls the scraper 11 to rotate and switch to the extended state that stands upright along the radial direction of the processing tank 1. At this time, the second rotation drive component 14 on the support frame 121 drives the tank body 13 to rotate. Since the scraper 11 is fixed on the covers 12 and remains stationary, during the rotation of the tank body 13, the extended scraper 11 always adheres to the inner wall of the tank body 13, and performs comprehensive mechanical scraping of the bottom, corners and other blind areas of the tank body 13, thoroughly removing stubborn adhering materials. Since the position of the scraper 11 is stationary relative to the covers 12, the impurities cleaned will always be near the scraper 11, which is convenient for operators to perform centralized processing, further optimizing the carbon fixation effect and the tank wall cleaning effect, and reducing equipment maintenance costs.

[0036] Reference Figure 5 and Figure 6 The control mechanism 3 includes a mounting base 31 and a third rotary drive assembly 32. The mounting base 31 is disposed on the cover 12, and a movable seat 311 is slidably mounted on the mounting base 31. The movable seat 311 is provided with a first elastic element 312, and the two ends of the first elastic element 312 are respectively connected to the mounting base 31 and the movable seat 311. The scraper 11 is provided with a rotating shaft that is rotatably connected to the movable seat 311. The third rotary drive assembly 32 is disposed on the movable seat 311 and is used to drive the rotating shaft to rotate.

[0037] This invention achieves the function of driving the scraper 11 to rotate through the mounting base 31 and the third rotary drive assembly 32, thus achieving the effect of switching the state of the scraper 11. During operation, when it is necessary to clean the inner wall of the treatment tank 1, the carbon fixation operation is first paused, and the control mechanism 3 starts working. The third rotary drive assembly 32, which is set on the movable base 311, drives the rotating shaft to rotate, thereby driving the scraper 11 to rotate, so that the scraper 11 switches from a contracted state that is in contact with the inner wall of the treatment tank 1 to an extended state that is upright along the radial direction of the treatment tank 1. The first elastic element 312 can push the movable base 311 to slide according to the slight displacement when the tank body 13 rotates, so that the scraper 11 is always in close contact with the inner wall of the tank body 13, ensuring uniform scraping force, avoiding gaps between the scraper 11 and the tank wall that would lead to incomplete cleaning, and at the same time buffering the impact force between the scraper 11 and the tank wall, reducing the wear of the scraper 11 and extending its service life. After the scraper 11 switches to the extended state, the second rotary drive assembly 14 on the support frame 121 drives the tank 13 to rotate. Since the scraper 11 is fixed to the cover 12 and remains stationary, during the rotation of the tank 13, the extended scraper 11 continuously adheres to the inner wall of the tank 13, thoroughly scraping away the adhering material in blind spots such as the bottom and corners of the tank 13, completely removing stubborn adhering substances. The cleaned impurities remain near the scraper 11, facilitating centralized processing by operators. After cleaning, the third rotary drive assembly 32 drives the shaft to rotate in the opposite direction, causing the scraper 11 to switch back to the retracted state. The second rotary drive assembly 14 stops driving the tank 13 to rotate, and then the carbon fixation operation resumes. The coordinated operation of all structures ensures the cleaning effect of the tank wall while avoiding interference with the carbon fixation operation during the cleaning process, reducing equipment maintenance costs and improving the overall stability and reliability of the operation.

[0038] Reference Figure 2 , Figure 3 and Figure 5 The cover 12 is provided with a limiting mechanism 4, which includes a limiting component 41 and a control component 42. The limiting component 41 is used to limit the rotation of the scraper 11. The control component 42 is used to release the limiting component 41 from limiting the rotation of the scraper 11.

[0039] This invention achieves the function of limiting the rotation of the scraper 11 through the limiting component 41 and the control component 42, thereby controlling the timing of the scraper 11's rotation and preventing it from standing upright during the carbon fixation process and affecting the stirring effect. During operation, when cleaning is not required, the limiting component 41 in the limiting mechanism 4 restricts the rotation of the scraper 11, preventing it from accidentally switching to the extended state and interfering with stirring and carbon fixation. When tank wall cleaning is required, the control component 42 is activated, releasing the limiting component 41 from restricting the rotation of the scraper 11, allowing the scraper 11 to rotate normally and switch to the extended state, cooperating with the rotation of the tank body 13 to complete the cleaning operation. After cleaning is completed, the control component 42 controls the limiting component 41 to reset, re-limiting the rotation of the scraper 11 to ensure the smooth progress of subsequent carbon fixation operations, while preventing the scraper 11 from being worn due to accidental rotation or affecting the operation of other structures.

[0040] Reference Figure 5 , Figure 8 , Figure 9 and Figure 10 The limiting component 41 includes a first support 411, a locking block 412, and a second elastic element 413. The first support 411 is disposed on the cover 12. The locking block 412 is slidably mounted on the first support 411. The scraper 11 has a slot that cooperates with the locking block 412. When the scraper 11 is in a retracted state, the locking block 412 is inserted into the slot under the elastic force of the second elastic element 413. The two ends of the second elastic element 413 are respectively connected to the first support 411 and the locking block 412.

[0041] The present invention achieves the function of restricting the rotation of the scraper 11 through the first support 411, the locking block 412 and the second elastic member 413.

[0042] Reference Figure 5 , Figure 8 , Figure 9 and Figure 10 The control component 42 includes an extension block 421, a control rod 422, and a push block 423. The extension block 421 is connected to the locking block 412, and the extension block 421 has an inclined guide groove. The control rod 422 is slidably mounted on the first support 411. The push block 423 is disposed on the control rod 422. As the control rod 422 moves away from the first support 411, the push block 423 presses against the inclined guide groove, thereby driving the locking block 412 to move closer to the first support 411.

[0043] This invention achieves precise control of the control mechanism 3, solving the technical problems of cumbersome operation and unsmooth unlocking of the traditional limiting mechanism 4, while ensuring stable and reliable state switching of the scraper 11. During operation, when it is necessary to release the constraint of the limiting component 41 on the scraper 11, the control rod 422 is pushed to move away from the first support 411. The push block 423 on the control rod 422 moves synchronously, and the push block 423 presses the inclined guide groove on the extension block 421. Due to the inclination angle of the inclined guide groove, the push block 423 will drive the extension block 421 to move closer to the first support 411. The extension block 421 is linked to the locking block 412 to move synchronously, so that the locking block 412 overcomes the elastic force of the second elastic element 413 and disengages from the slot connection with the scraper 11, releasing the restriction on the scraper 11. When it is necessary to re-restrict the scraper 11, the control rod 422 is released, the second elastic element 413 pushes the extension block 421 to reset, and the locking block 412 engages with the slot of the scraper 11 again, realizing the limitation of the scraper 11.

[0044] Reference Figure 5 , Figure 8 , Figure 9 and Figure 10 The control component 42 further includes a connecting rod 424 and an abutment block 425; the connecting rod 424 is connected to the control rod 422; the abutment block 425 is disposed on the connecting rod 424 and abuts against the inner wall of the tank 13.

[0045] This invention achieves the function of automatically releasing the rotation restriction on the scraper 11 when the tank body 13 rotates. During operation, when tank wall cleaning is required, the second rotation drive assembly 14 drives the tank body 13 to rotate. During the rotation of the tank body 13, friction is generated between the inner wall of the tank body 13 and the abutment block 425. This friction pushes the abutment block 425 to move, and the abutment block 425 moves synchronously with the linkage connecting rod 424. The connecting rod 424 drives the control rod 422 to move away from the first support 411. The push block 423 on the control rod 422 moves accordingly and presses the inclined guide groove on the extension block 421, driving the extension block 421 and the locking block 412 to move closer to the first support 411. This causes the locking block 412 to overcome the elastic force of the second elastic element 413 and disengage from the locking groove on the scraper 11, automatically releasing the rotation restriction on the scraper 11. At this time, the third rotary drive assembly 32 drives the shaft on the scraper 11 to rotate, causing the scraper 11 to switch to the extended state. In conjunction with the continuous rotation of the tank 13, the inner wall of the tank 13 is thoroughly scraped. The cleaned impurities are concentrated near the scraper 11 for easy subsequent centralized processing. After cleaning, the second rotary drive assembly 14 stops driving the tank 13 to rotate. The friction between the inner wall of the tank 13 and the abutment block 425 disappears. The second elastic element 413 releases its elastic force, pushing the locking block 412 and the extension block 421 to reset. The locking block 412 re-engages with the slot of the scraper 11. At the same time, the extension block 421 pushes the push block 423, control rod 422, connecting rod 424 and abutment block 425 to reset through the inclined guide groove. The abutment block 425 continues to abut against the inner wall of the tank 13, preparing for the next cleaning operation.

[0046] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 The mounting base 31 is provided with a support base 313, which abuts against the support base 313 when the scraper 11 is in the extended state.

[0047] This invention improves the support stability of the scraper 11, preventing it from shifting or shaking during cleaning operations, ensuring cleaning effectiveness, and solving the problem of easy displacement and reduced cleaning accuracy when the scraper 11 is in the extended state. During operation, a support seat 313 is provided on the mounting base 31. When the scraper 11 switches to the extended state, it abuts against the support seat 313, which provides stable support and prevents the scraper 11 from shifting position due to factors such as tank body 13 rotation or material impact. This ensures the scraper 11 remains in contact with the inner wall of the tank body 13, guaranteeing the stability and thoroughness of the scraping.

[0048] Reference Figure 5 The control mechanism 3 also includes a sealing cover 33 for isolating the third rotary drive assembly 32.

[0049] This invention protects the third rotary drive assembly 32 from external interference, extending its service life. During operation, the sealing cover 33 isolates the third rotary drive assembly 32, preventing materials, moisture, or impurities from the cement-based recycled micro-powder concrete from entering its interior and causing malfunctions. When cleaning the tank wall or performing carbon fixation operations, the sealing cover 33 effectively protects the third rotary drive assembly 32 from contamination or damage, ensuring that it can stably drive the shaft to rotate, thereby driving the scraper 11 to complete the cleaning operation.

[0050] Reference Figure 1 and Figure 2 The support frame 121 is provided with a second support 15, and a roller 151 that is rotatably connected to the outer wall of the tank 13 is provided on the second support 15.

[0051] This invention provides stable support for the tank 13 during rotation, solving the technical problem of easy displacement of the tank 13 during the rotation cleaning process. During operation, when the second rotary drive assembly 14 drives the tank 13 to rotate for inner wall cleaning, the roller 151 rolls synchronously with the tank 13, providing multi-point support to the outer wall of the tank 13, reducing radial swaying during rotation. Simultaneously, rolling friction replaces sliding friction, reducing the rotational resistance of the tank 13 and ensuring more stable and reliable rotation. This, combined with the extended scraper 11, provides stable scraping and cleaning of the inner wall of the tank 13, preventing uneven contact between the scraper 11 and the tank wall due to tank 13 swaying.

[0052] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
