Abstract
Description
Technical Field
[0001] This invention relates to the field of magnesium-calcium brick processing technology, and in particular to an environmentally friendly magnesium-calcium brick processing device. Background Technology
[0002] Environmentally friendly magnesium-calcium bricks use magnesia and lime as raw materials. The core of its processing equipment is a highly efficient and uniform mixing and stirring process. The operation process usually includes precise feeding of raw materials (magnesia, lime and environmentally friendly binder), strong stirring of dry or wet (binder), homogenization and discharge of the mixture, and subsequent molding preparation.
[0003] In wet mixing processes using calcium-containing materials (especially quicklime) and trace amounts of water-based environmentally friendly binders, calcium-containing materials tend to form a hard adhesive layer on the drum wall due to the influence of drum wall temperature, material friction heat generation, and ambient humidity. Conventional scraper cleaning devices that rotate with the stirring shaft are also prone to forming an adhesive layer on the scraper surface due to the synchronous movement of the scraper and the stirring shaft, which also affects the mixing effect. Summary of the Invention
[0004] Based on the technical problems in the background art, the present invention proposes an environmentally friendly magnesium-calcium brick processing device.
[0005] This invention proposes an environmentally friendly magnesium-calcium brick processing device, comprising a vessel and a vessel lid. A stirring shaft connected to a drive motor is disposed in the middle of the vessel. The stirring shaft extends vertically at the center of the vessel, and stirring blades are fixed to the outer wall of the stirring shaft. A slip ring is horizontally installed at the top of the vessel. Multiple sliding rods are slidably connected to the outer wall of the slip ring. A scraper that fits against the inner wall of the vessel is fixed to the bottom end of the sliding rod. A spring connects the sliding rod and the slip ring. The rotation direction of the stirring shaft is set from the spring towards the sliding rod, actively driving the sliding rod and scraper to rotate a certain distance and stretching the spring, and then using the spring to reset.
[0006] Preferably, a guide connecting frame is fixedly provided on the inner side of the slip ring. The outer circumference of the guide connecting frame is provided with an arc-shaped groove at the position corresponding to the slide rod. Under normal conditions, when the spring is not stretched, the slide rod is in contact with one side of the groove. During movement, the slide rod is actively driven to rotate towards the other side of the groove until the slide rod is in contact with the other side of the groove.
[0007] Preferably, a plurality of connecting rods are fixed on the outer wall of the stirring shaft at the position corresponding to the slip ring, and a second annular groove is opened on the inner side of the guide connecting frame at the position corresponding to the connecting rod. The outer wall of the connecting rod is slidably connected to the second groove. A magnetic block is fixed on the end of the connecting rod facing the slide rod, and a magnetic block is fixed on the end of the slide rod facing the connecting rod.
[0008] Preferably, a tension monitoring module is provided at both ends of the spring to monitor the tension value of the spring in real time. A pressure monitoring module is provided on both sides of the slide groove to monitor the collision pressure value between the slide rod and both sides of the slide groove. Both the tension monitoring module and the pressure monitoring module are connected to the data acquisition and processing unit.
[0009] Preferably, during a complete motion cycle in which the slide rod is driven to rotate by magnetic force and collides with the other side of the slide groove, and then resets and collides with the initial side of the slide groove, the corresponding spring tension change data, the first collision pressure value of the slide rod colliding with the initial side of the slide groove, and the second collision pressure value of the slide rod colliding with the other side of the slide groove are synchronously collected and recorded; based on the tension change data, the tension growth rate of the spring during the stretching phase is calculated; based on the first collision pressure value and the second collision pressure value, a comprehensive collision pressure evaluation value is calculated.
[0010] Preferably, the calculated real-time tensile force growth rate and real-time comprehensive collision pressure assessment value are compared with the normal state baseline value established in advance through experimental or break-in period data; based on the comparison results, the adhesion state of the inner wall of the vessel or the surface of the scraper in the corresponding area is determined, and the adhesion state includes at least the normal state, the warning state, and the alarm state; the determination result of the adhesion state is output, and the staff is reminded when the state is the warning state or the alarm state.
[0011] Preferably, when the spring is in its normal position, the scraper can cover the corresponding area of the spring and the slide bar in the horizontal direction, and when the spring is stretched to its maximum value, the scraper can contact the corresponding area of the adjacent spring in the horizontal direction.
[0012] Preferably, the stirring blades outside the stirring shaft are arranged in two vertical groups, with four blades in each group. The blades are configured with wide blades and narrow blades. The width of the wide blades gradually increases in the direction away from the stirring shaft, and the width of the narrow blades gradually decreases in the direction away from the stirring shaft. In the same group, the wide blades and narrow blades are arranged alternately, and the wide blades and narrow blades are arranged correspondingly between adjacent groups.
[0013] Preferably, the difference in the number of the slide rod and the connecting rod is at least one.
[0014] Preferably, the outer wall of the slide bar has multiple vertically distributed mounting grooves, with both ends of the mounting grooves penetrating through. A bearing seat is fixed to the inner wall of both sides of the mounting groove, and a shaft is rotatably connected between the two bearing seats. A blade is fixed in the middle of the shaft, and the blade extends in the tangential direction of the vessel. V-grooves are provided on both sides of the blade.
[0015] The beneficial effects of this invention are as follows:
[0016] 1. In this invention, the scraper and the stirring shaft are dynamically moved relative to each other, and the surface of the scraper is cleaned by the change of liquid flow. This avoids the scraper from sticking together because it is always in a fixed position relative to the stirring shaft. By utilizing the change of liquid flow, adhesion on the surface of the stirring shaft and the stirring blades can be avoided. During the reciprocating motion of the slide rod, the slide rod will collide with the inner walls of both sides of the slide groove, which further improves the cleaning and anti-adhesion effect on the surface of the slide rod and the scraper, thereby effectively improving the mixing effect of magnesium-calcium brick preparation and improving the quality of the finished product.
[0017] 2. In this invention, by monitoring the change in spring tension and the numerical monitoring of the sliding rod collision pressure, the signal source is the direct mechanical feedback when the scraper is working, which is more accurate than the indirect monitoring of motor current, realizing continuous health monitoring in the production process. This allows for effective and stable monitoring of the adhesion status of the inner wall of the vessel, and the output structured data lays a solid foundation for future predictive maintenance and automatic adjustment of process parameters.

[0027] Example 1: Refer to Figures 1-6 An environmentally friendly magnesium-calcium brick processing device includes a reactor 1 and a reactor lid 2. A discharge pipe 101 is connected to the bottom of the reactor 1, and a feed pipe 201 is connected to the top of the reactor lid 2. A stirring shaft 3, which is driven by a drive motor 5, is installed in the middle of the reactor 1. The stirring shaft 3 extends vertically at the center of the reactor 1, and the top of its outer circumference is rotatably connected to the reactor lid 2 via a sealed bearing. The drive motor 5 is installed on the top of the reactor lid 2, and its output shaft is driven by the top of the stirring shaft 3. Stirring blades 4 are fixed to the outer wall of the stirring shaft 3. Inside the reactor 1… A sliding ring 6 is horizontally installed at the top position. A bracket 601 is fixed between the top of the sliding ring 6 and the vessel cover 2. The sliding ring 6, the stirring shaft 3, and the inner wall of the vessel 1 are coaxial. Multiple sliding rods 7 are slidably connected to the outer wall of the sliding ring 6. A scraper 8 that fits against the inner wall of the vessel 1 is fixed to the bottom end of the sliding rod 7. A spring 10 connects the sliding rod 7 and the sliding ring 6. It should be noted that the sliding rod 7 is set as a ring at the corresponding position of the sliding ring 6. The inner wall of the ring slides in contact with the outer wall of the sliding ring 6. A fixing plate 9 is installed on the sliding ring 6 at the position corresponding to each sliding rod 7. The two ends of the spring 10 are respectively connected to the ring. The body and the fixed plate 9 are fixedly connected, and the bracket 601 is set close to the fixed plate 9, so that the fixed plate 9 is positioned between the bracket 601 and the spring 10; the rotation direction of the stirring shaft 3 is set from the spring 10 towards the slide rod 7, actively driving the slide rod 7 and the scraper 8 to rotate a certain distance and stretch the spring 10, and then using the spring 10 to reset. In use, the drive motor 5 drives the stirring shaft 3 and the stirring blade 4 to continuously rotate in a circular motion to perform stirring and mixing operations, and causes the stirring blade 4 to rotate from the spring 10 towards the corresponding slide rod 7, while the slide rod 7 rotates towards the slide rod 7. The rod 7 and scraper 8 reciprocate in the circumferential direction under the active drive and the action of the spring 10. On the one hand, the coverage area of multiple scrapers 8 ensures the scraping and cleaning effect on the bottom of the inner wall of the vessel 1. On the other hand, the dynamic relative movement between the scraper 8 and the stirring shaft 3 is used to clean the surface of the scraper 8 by utilizing the changes in liquid flow, so as to avoid the scraper 8 from sticking to the stirring shaft 3 by always being in a fixed position. By utilizing the changes in liquid flow, adhesion can be avoided on the surface of the stirring shaft 3 and the stirring blade 4, thereby effectively improving the mixing operation effect of magnesium-calcium brick preparation and improving the quality of the finished product.
[0028] In this invention, a guide connecting frame 14 is fixedly installed inside the slip ring 6 and outside the stirring shaft 3. A bracket 141 is fixedly connected between the top of the guide connecting frame 14 and the vessel cover 2. The guide connecting frame 14 is coaxially arranged with the stirring shaft 3, the slip ring 6, and the vessel 1. An arc-shaped groove 143 is formed on the outer circumference of the guide connecting frame 14 at a position corresponding to the slide rod 7. The slide rod 7 extends horizontally toward the guide connecting frame 14. Under normal conditions, when the spring 10 is not stretched, the slide rod 7 contacts one side of the groove 143. During movement, the slide rod 7 is actively driven. The slide rod 7 rotates towards the other side of the slide groove 143 until it contacts the other side of the slide groove 143. When the slide rod 7 and scraper 8 are actively driven to rotate, the slide rod 7 will collide with the inner wall of the other side of the slide groove 143 when it reaches its maximum rotation. Then the spring 10 pulls the slide rod 7 to reset and swing back and forth until the subsequent active drive starts, which will reset the slide rod 7 to collide with the inner wall of one side of the slide groove 143. Thus, during the reciprocating motion of the slide rod 7, the slide rod 7 will collide with the inner walls of both sides of the slide groove 143, so as to further improve the cleaning and anti-adhesion effect on the surface of the slide rod 7 and scraper 8.
[0029] In this invention, multiple connecting rods 12 are fixed to the outer wall of the stirring shaft 3 at positions corresponding to the slip ring 6. A second annular groove 142 is formed on the inner side of the guide connecting frame 14 at positions corresponding to the connecting rods 12. The outer wall of the connecting rod 12 is slidably connected to the second groove 142 to ensure smooth movement of the connecting rod 12 with the circumferential motion of the stirring shaft 3. It should be noted that both the connecting rod 12 and the slip rod 7 have annular grooves at positions corresponding to the guide connecting frame 14, allowing for limited sliding contact between the annular groove of the connecting rod 12 and the second groove 142, and limited sliding contact between the annular groove of the slip rod 7 and the first groove 143. A magnetic block 13 is fixed to the end of the connecting rod 12 facing the slip rod 7, and a magnetic suction block 11 is fixed to the end of the slip rod 7 facing the connecting rod 12. Through the magnetic attraction between the magnetic block 13 and the magnetic suction block 11, when the magnetic block 13 rotates with the stirring shaft 3 to a position close to the slip rod 7, it will pull the slip rod 7 closer to the first groove 143 under magnetic attraction. The slide bar 7 and scraper 8 rotate with the stirring shaft 3 under strong magnetic attraction, until the slide bar 7 collides with the other side of the trough 143 and is stopped. After the magnetic block 13 continues to rotate and disengages from the position of the slide bar 7, the slide bar 7 reciprocates under the action of the spring 10 and gradually returns to its original position until the magnetic block 13 approaches again. This achieves active driving of the slide bar 7 and collision operation of the slide bar 7. Furthermore, through the contact between the guide connecting frame 14 and the slide bar 7 and the connecting rod 12, the mechanical vibration generated by the collision of the slide bar 7 is transmitted to the stirring shaft 3 through the connecting rod 12, which further avoids the sticking at the bottom of the stirring shaft 3. Thus, the overall setting improves the mixing operation effect and the quality of the finished product. It should be noted that the magnetic block 13 can be a permanent magnet or an electromagnetic block. When an electromagnetic block is used, it is energized through an electric slip ring structure, and the magnetic force can be adjusted according to the material concentration or situation to ensure the effectiveness of active driving of the slide bar 7 to rotate and collide.
[0030] In this invention, when the spring 10 is in its normal position, the scraper 8 can cover the corresponding areas of the bracket 601, the fixing plate 9, the spring 10, and the slide bar 7 in the horizontal direction. When the spring 10 is stretched to its maximum value, the scraper 8 can contact the corresponding area of the adjacent spring 10 in the horizontal direction. It should be noted that when the spring 10 is stretched to its maximum value, the scraper 8 corresponding to that position moves to its farthest distance, while the scraper 8 at the adjacent position, because the magnetic block 13 has not yet approached, is still reciprocating under the action of the spring 10. Therefore, the adjacent scrapers 8 will not collide or be blocked due to a small overlapping area being scraped. This ensures that the scraping operation of multiple scrapers 8 is carried out in sections and can cover the entire inner wall of the vessel 1.
[0031] In this invention, the stirring blades 4 outside the stirring shaft 3 are arranged in two vertical groups, with four blades in each group. The blades are configured with wide blades and narrow blades. The width of the wide blades gradually increases in the direction away from the stirring shaft 3, and the width of the narrow blades gradually decreases in the direction away from the stirring shaft 3. In the same group, the wide blades and narrow blades are arranged alternately, and in adjacent groups, the wide blades and narrow blades are arranged correspondingly. Thus, the liquid is dispersed and guided by the wide blades and narrow blades arranged alternately in the stirring blades 4 during rotation, thereby improving the dispersion effect of the liquid flow and the mixing effect. At the same time, the shear force of the dispersed liquid flow can effectively improve the cleaning effect of the relatively moving scraper 8.
[0032] In this invention, the difference in the number of slide rods 7 and connecting rods 12 is at least one, meaning that the number of slide rods 7 and connecting rods 12 is not the same. For example, as shown in the attached diagram: three slide rods 7 and four connecting rods 12 are provided. By setting an odd number of slide rods 7 and connecting rods 12, all slide rods 7 will not start being actively driven to rotate simultaneously, nor will they rotate to their furthest positions at the same time. Therefore, there will be relative movement between multiple slide rods 7 and the scraper 8, thereby improving the liquid dispersion effect. Furthermore, through the relative movement between multiple slide rods 7, the collision of the slide rods 7 with the guide connecting frame 14 will vary, thereby improving the cleaning effect on the scraper 8 and the stirring shaft 3. It should be noted that the monitoring of the scraped area targets the change in the tension value of the corresponding spring 10 and the collision pressure value on both sides of the corresponding slide rod 7. Therefore, the vibration transmitted by the collision of slide rods 7 at other positions will not affect the monitoring and analysis results. Thus, through this overall scheme, the cleaning effect on the surfaces of the vessel 1, scraper 8, and stirring shaft 3 is improved, while also ensuring effective monitoring of the scraped area.
[0033] In this invention, a miniature S-shaped tension sensor is connected in series at both ends of each spring 10, i.e., at the connection points with the rings on the fixed plate 9 and the slide rod 7. The sensor must be corrosion-resistant and fatigue-resistant, and its range must cover the entire tension range of the spring 10 from the free state to the maximum tension state. The signal line of the tension sensor is converged through the wire grooves pre-cut on the bracket 601 and the slip ring 6 to a wireless transmitting module, such as a Bluetooth or Zigbee module, fixed at the top center of the lid 2, or led out to the outside of the lid through a miniature slip ring electrical connector mounted on the slip ring 6 to connect to the main control system. A wireless solution is preferred to simplify the wiring on the rotating structure.
[0034] In this invention, a micro-thin-film piezoelectric sensor or strain gauge pressure sensor is embedded on each of the inner walls of the slide groove 143 on both sides of the guide connecting frame 14. These sensors should be installed flat with their surfaces flush with the inner wall of the slide groove to avoid affecting the sliding of the slide rod 7. The signal lines of the pressure sensors are integrated inside the guide connecting frame 14 and led out through the cavity inside the bracket 141 to the top of the lid 2 and connected to the main control system.
[0035] In this invention, an industrial-grade embedded PLC or microcontroller, such as the STM32 series, is used as the core. This unit is responsible for: synchronously acquiring analog signals from all tension and pressure sensors at a high frequency (≥1000Hz is recommended); performing analog-to-digital conversion and filtering; implementing a running status recognition algorithm; outputting results and triggering alarms; the specific configuration is as follows:
[0036] Step 1: Data Synchronization and Feature Extraction
[0037] Within a complete "magnetic attraction-rotation-collision-reset" cycle, that is, from the moment the slider 7 is attracted away from the slide groove 143 by the magnetic block 13 until it is reset and collides with the same side again, the system synchronously records the following timing data:
[0038] F(t): The curve of the tension value of spring 10 changing with time;
[0039] P1: The instantaneous pressure peak value when sliding rod 7 and sliding groove 143 collide on the initial side and reset collision side;
[0040] P2: The slide bar 7 is driven to rotate to the farthest position, and the instantaneous pressure peak when it collides with the other side of the slide groove 143 at the end collision side.
[0041] Step 2: Calculation of key feature parameters:
[0042] Extract the following key feature values from the original data:
[0043] 1. Tension growth rate k: Calculate the approximate slope of the tension-time curve of spring 10 during the stretching phase, from the point where the tension begins to rise significantly until it reaches its peak. This value reflects the resistance that needs to be overcome when driving the scraper 8 to rotate. The resistance mainly comes from the shear force of the adhesive between the scraper and the vessel wall.
[0044] 2. Collision Stress Assessment Value E: Defines an assessment value for the overall collision stress, for example, Where α and β are weighting coefficients, which can be calibrated experimentally. The initial side impact is more sensitive to the instantaneous adhesion state after the scraper resets; the values of P1 and P2 reflect the kinetic energy of the slide bar 7 system at the extreme position collision, which is related to the inertia and resistance of the motion system.
[0045] Step 3: Establish a state judgment model and set thresholds:
[0046] Establish a baseline of characteristic values under normal conditions by accumulating data from previous experiments or equipment break-in periods;
[0047] After new equipment is put into use or thoroughly cleaned, multiple batches of normal mixed production are carried out. The k and E values of the corresponding sensor for each scraper are recorded in each cycle, and their statistical average value is calculated. ) and standard deviation ( );
[0048] State determination logic:
[0049] Normal status: and ;
[0050] Warning signs of mild adhesion: k continues to increase, exceeding... However, the change in E is not significant, indicating that the sliding resistance of the scraper has increased, but the overall inertial impact has not changed significantly, which may be due to uniform thin-layer bonding.
[0051] Alarm status for moderate adhesion: k increases significantly, while E, especially P1, decreases significantly, indicating that the resistance is so great that it affects the reset speed and impact kinetic energy of the slide bar, and the adhesion is quite serious;
[0052] Severe conditions of localized hard block adhesion or mechanical jamming: abnormal fluctuations or sharp increases in the k value, while P1 or P2 are missing (no collision signal detected) or have extremely low values, indicating that the motion process may be severely hindered.
[0053] Step 4: System Output and Linkage
[0054] The human-machine interface (HMI) displays the number of each scraper 8, the current k and E values, historical trend curves, and the determined status in real time;
[0055] When the status enters the warning or higher level, the system triggers an audible and visual alarm and locates and prompts on the HMI which scraper area has a problem;
[0056] All data is stored in a database and can be linked to production batch numbers for quality traceability and process analysis.
[0057] Through the above overall setup, the signal source is the direct mechanical feedback from the scraper during operation, which is more accurate than indirect monitoring of motor current, enabling continuous health monitoring during the production process. This allows for effective and stable monitoring of the adhesion status of the inner wall of the vessel, and the output structured data lays a solid foundation for future predictive maintenance and automatic adjustment of process parameters.
[0058] For ease of understanding, an application example is provided in an environmentally friendly magnesia-calcium brick production line, where the apparatus of this embodiment is used for wet mixing of magnesia and lime:
[0059] 1. Initial state: After the equipment is cleaned and put into operation, the main control system learns the baseline value of a certain scraper area. , (Dimensionless).
[0060] 2. Operation process: After 10 batches of continuous production, the system monitored that the k value in this area slowly rose to 65 N / s, and the E value stabilized at 115.
[0061] 3. System judgment: The value of k has exceeded the warning threshold (assuming) The system determines that the area of the vessel wall corresponding to the scraper has entered a "mild adhesion warning" state.
[0062] 4. Operation Response: The scraper icon on the central control room HMI will flash yellow. The operator can take one of the following actions:
[0063] Manual confirmation: After the next discharge, check the area through the observation port to confirm that there is slight wall slagging.
[0064] Process fine-tuning: Appropriately increase the atomization degree of the binder in this batch or slightly reduce the feeding speed.
[0065] Initiate auxiliary cleaning: Manually or automatically trigger a targeted cleaning procedure for the area.
[0066] 5. Effect Verification: After the intervention measures were taken, the next production cycle was monitored and the k value was found to have dropped back to about 55 N / s, and the system status returned to normal, thus verifying the effectiveness of the monitoring and the correctness of the intervention measures.
[0067] Example 2: Refer to Figure 1 and Figures 4-8 An environmentally friendly magnesium-calcium brick processing device, based on Example 1, has multiple vertically distributed mounting grooves 15 on the outer wall of the slide rod 7. The two ends of the mounting grooves 15 are penetrating, and the inner walls on both sides of the mounting grooves 15 are fixed with bearing seats 16. A shaft rod 17 is rotatably connected between the two bearing seats 16. An blade rod 18 is fixed in the middle of the shaft rod 17. The blade rod 18 extends in the penetrating direction of the mounting grooves 15 and in the tangential direction of the vessel 1. V-shaped grooves are provided on both sides of the blade rod 18. During the relative movement of the slide rod 7 and the stirring shaft 3 and under the action of liquid flow, the blade rod 18 swings vertically with the shaft rod 17, thereby dispersing the local liquid flow near the inner wall of the vessel 1 to further improve the dispersion and mixing effect.
