Description

Technical Field

[0001] This utility model relates to the field of cement clinker mixing technology, and more specifically, to a cement clinker mixing device. Background Technology

[0002] With the rapid development of the construction industry and the continuous progress of cement production technology, clinker mixing equipment, as a key link in the cement production line, plays a crucial role in the stable operation of the entire production process. However, in the existing technical solutions, there are still many technical problems that need to be solved in the design of protection mechanisms for cement clinker mixing equipment.

[0003] Firstly, in the design of conventional cement clinker mixing equipment, to prevent motor overload damage or mixing rod breakage due to abnormal conditions such as excessive material hardness, foreign object intrusion, or mixing stall, a special protective device is usually installed at the connection between the motor and the mixing rod. These devices automatically disconnect power transmission when the mixing torque exceeds a preset threshold, effectively preventing equipment damage and production accidents. However, the protection threshold of such devices is usually a fixed value from the factory and cannot be precisely and flexibly adjusted according to different clinker material ratios, production batch characteristics, mixing speed requirements, and actual production environment. This "one-size-fits-all" protection mechanism often fails in actual production. This often leads to two extreme situations: On the one hand, if the protection threshold is set too high, it may not be able to cut off the power transmission in time, causing the motor to overload and burn out or the stirring rod to break, resulting in equipment damage and production line shutdown; on the other hand, if the protection threshold is set too low, the protection mechanism may be frequently triggered during normal stirring, leading to frequent production interruptions, which seriously affects production efficiency and product quality stability. In addition, with the increasing diversification of cement products with different grades and performance in the cement industry, the clinker material ratio required for stirring during the production process changes more and more frequently, and the limitations of fixed protection thresholds become more and more obvious, which can no longer meet the high requirements of modern cement production lines for equipment flexibility and adaptability.

[0004] Secondly, while some improved clinker mixing equipment on the market has indeed superficially achieved flexible adjustment of the protection threshold, enabling the equipment to adapt to different material ratios and production needs to a certain extent, these improved designs still have significant shortcomings in practical applications: their adjustment mechanism design is too simple and crude, the locking mechanism after adjustment is not reliable enough, and there is a lack of effective secondary locking or anti-loosening devices. These design defects lead to the easy occurrence of slight displacement or creep loosening of the adjusted components in actual production environments, especially under conditions such as long-term high-speed operation, strong vibration, and frequent start-stop of the mixing equipment. This causes the carefully adjusted protection threshold to gradually shift. More seriously, this threshold shift is often difficult to detect in daily operation and may accumulate to a level that is sufficient to affect the safe operation of the equipment. Once an abnormality suddenly occurs during production, the difference between the adjusted protection threshold and the actual working threshold may cause the protection device to fail to trigger at the designed time, which may not only cause serious damage to the equipment but also trigger a chain reaction, affecting the safe and stable operation of the entire production line. In addition, the instability of the adjustment mechanism also increases the workload and difficulty of daily equipment maintenance. Operators need to frequently check and readjust the protection threshold, which greatly increases the equipment operation and maintenance costs and management difficulty. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: a cement clinker mixing device, comprising a mixing rod, a protective rod fixedly connected to the top of the mixing rod, a protective sleeve rotatably mounted on the outer side of the protective rod, a control sleeve rotatably mounted on the outer side of the protective sleeve, a drive wheel fixedly connected to one side of the control sleeve, a protective groove formed on the outer side of the protective rod, a fixed plate fixedly mounted on the outer side of the protective sleeve, a plurality of threaded sleeves rotatably mounted on the fixed plate, a driven wheel fixedly connected to one side of each threaded sleeve, the plurality of driven wheels respectively meshing with the drive wheel, a movable sleeve slidably mounted on the outer side of the protective sleeve, a screw fixedly connected to one side of the movable sleeve, the threaded sleeve being movably connected to the screw through threads, and one end of the protective sleeve being rotatably connected to... A control sleeve is provided, with multiple movable blocks movably mounted on one side of the control sleeve.

An adapter is movably mounted on the inner side of the control sleeve. Multiple fixed blocks are fixed on the outer side of the protective sleeve, and an adapter block is fixed on the outer side of the adapter. An inclined groove is provided on the inner side of the protective sleeve, with an inclined plate sliding in the inclined groove. A movable block is fixedly connected to one side of the inclined plate. A clearance groove is provided on the inner side of the movable block, with a movable spring movably mounted in the clearance groove. A protective block is movably mounted in the protective groove, with each end of the movable spring connected to the protective block and the inner wall of the clearance groove, respectively. An adapter groove is spirally provided on the inner wall of the control sleeve, with the adapter block sliding in the adapter groove.

[0009] The present invention is further configured such that a support is provided on the outside of the stirring rod, a stirring tank is detachably provided on the support, a fixed cover is detachably provided on the top of the stirring tank, a tank cover is rotatably connected to both sides of the fixed cover via a rotating shaft, and the stirring rod rotates to be inside the stirring tank, and a stirring rack is detachably provided on the outside of the stirring rod.

[0010] The present invention is further provided with a handle fixedly provided at the top of the can lid. The handle allows the operator to open and close the can lid conveniently and quickly, improving the ease of operation for adding raw materials and inspecting equipment during the production process.

[0011] The present invention is further configured such that a feed pipe is connected above the fixed cover, a mounting bracket is detachably provided at the top of the fixed cover, a motor is detachably provided at the top of the mounting bracket, the motor output is detachably connected to the top of the protective sleeve, and a discharge pipe is connected to the top of the mixing tank.

[0012] The present invention is further configured such that a plurality of moving rails are fixedly provided on one side of the control sleeve, and a moving groove is provided in the moving block. The moving block is slidably installed on the outside of the moving rails through the moving groove. This precise sliding guide structure ensures that the moving block moves smoothly along the predetermined trajectory during the adjustment process, avoiding deviation and jamming, and improving the accuracy of the protection threshold adjustment and the smoothness of operation.

[0013] The present invention is further configured such that a movable wheel is rotatably mounted on one side of the movable block, and the movable wheel is engaged between two adjacent fixed blocks. The engaging design between the movable wheel and the fixed block forms a reliable mechanical locking structure, which effectively prevents the adjusted mechanism from rotating or displacing unexpectedly, greatly improves the stability of the protection threshold setting, and ensures smooth operation.

[0014] The present invention is further configured such that a mating groove is provided on one side of the adapter, and a mating block is fixedly connected to one side of the movable block.

[0015] The present invention is further configured such that the outer side of the protective block and the inner edge of the protective groove are both designed with rounded corners. The rounded corner design reduces the impact force and wear when the protective block contacts the protective groove, reduces the component wear rate, and ensures that the protective block can smoothly detach from the protective groove when the protection is triggered, thereby improving the response speed and working reliability of the protection mechanism.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a cement clinker mixing device, which has the following beneficial effects:

[0018] 1. An innovative protective threshold adjustment mechanism has been designed, completely solving the technical bottleneck of fixed protective device thresholds in existing technologies. The ingenious cooperation of the control sleeve, protective sleeve, protective rod, protective block, movable spring, movable block, and inclined plate in this device enables precise adjustment of the protective threshold. When the protective threshold needs adjustment, the user only needs to rotate the control sleeve. The spiral adapter groove inside the control sleeve drives the adapter block to slide, causing the adapter to push the movable block to move. The movable block drives the inclined plate to slide in the inclined groove, achieving precise control of the movable block's inward convergence. This changes the distance between the inner wall of the clearance groove and the movable block, generating different degrees of squeezing force on the movable spring, ultimately adjusting the release force required by the protective block. This structural design allows operators to steplessly and precisely adjust the protective threshold according to various factors such as different clinker material ratios, production batch characteristics, and mixing speed requirements. This avoids the risk of equipment damage due to excessively high protective thresholds and prevents frequent protection triggers and production interruptions caused by excessively low thresholds, greatly improving equipment adaptability and production line stability, and meeting the high requirements of modern cement production for equipment flexibility.

[0019] 2. A creative dual-locking protection mechanism is employed. Through the design of components such as the moving sleeve, moving rail, moving block, fixed block, control sleeve, driving wheel, driven wheel, screw, and screw sleeve, the technical problem of insufficient stability after adjusting the protection threshold in existing improved equipment is fundamentally solved. After the protection threshold adjustment is completed, the moving spring automatically resets, pulling the moving block to slide inward along the moving rail, causing the moving wheel on the moving block to engage with the adjacent fixed block, forming the first mechanical lock. Subsequently, by rotating the control sleeve in the reverse direction, the driving wheel rotates in the reverse direction. The meshing transmission between the driving wheel and the driven wheel causes the screw sleeve to rotate forward on the fixed plate. Through the threaded connection, the screw and moving sleeve slide in the reverse direction to the reset position. The positioning system ensures that the inner wall of the moving sleeve tightly fits against the outer wall of the moving wheel, forming a second mechanical lock. This innovative dual-locking mechanism design ensures that the adjusted protection threshold remains highly stable even under conditions such as prolonged high-speed operation, strong vibration, and frequent start-stop of the mixing equipment. This effectively prevents threshold deviation caused by minor component displacement or creep loosening, ensuring that the protection device can be triggered accurately at the designed time. This fundamentally avoids the risk of equipment damage and cascading failures in the production line. At the same time, this highly stable design significantly reduces the threshold inspection and readjustment work in daily equipment maintenance, significantly reducing equipment operation and maintenance costs and management difficulty, creating considerable economic benefits for cement production enterprises.

A movable spring 14 is provided on the outer side of the protective sleeve 3. The two ends of the movable spring 14 are respectively connected to two adjacent movable blocks 13. An adapter 15 is movably provided on the inner side of the control sleeve 12. Multiple fixed blocks 16 are fixedly provided on the outer side of the protective sleeve 3. An adapter block 17 is fixedly provided on the outer side of the adapter 15. An inclined groove 18 is opened on the inner side of the protective sleeve 3. An inclined plate 19 is slidably provided in the inclined groove 18. A movable block 20 is fixedly connected to one side of the inclined plate 19. A clearance groove 21 is opened on the inner side of the movable block 20. A movable spring 22 is provided in the clearance groove 21. A protective block 23 is movably provided in the protective groove 6. The two ends of the movable spring 22 are respectively connected to the inner wall of the protective block 23 and the clearance groove 21. An adapter groove 24 is spirally opened on the inner wall of the control sleeve 12. The adapter block 17 is slidably located in the adapter groove 24.

[0030] A support 25 is provided on the outside of the stirring rod 1. A stirring tank 26 is detachably provided on the support 25. A fixed cover 27 is detachably provided on the top of the stirring tank 26. A tank cover 28 is rotatably connected to both sides of the fixed cover 27 through a rotating shaft. The stirring rod 1 rotates to be inside the stirring tank 26. A stirring frame 29 is detachably provided on the outside of the stirring rod 1.

[0031] A handle 30 is fixedly provided at the top of the can lid 28.

[0032] A feed pipe 31 is connected above the fixed cover 27. A mounting bracket 32 ​​is detachably provided at the top of the fixed cover 27. A motor 33 is detachably provided at the top of the mounting bracket 32. The output of the motor 33 is detachably connected to the top of the protective sleeve 3. A discharge pipe 34 is connected to the top of the mixing tank 26.

[0033] In this embodiment, when the device is needed, first ensure that the discharge valve connected to the discharge pipe 34 is closed. Then connect the top of the feed pipe 31 to the external pipe. Then open the tank cover 28 using the handle 30. Add the solid raw material into the mixing tank 26 and transport water into the mixing tank 26 through the conveying device connected to the feed pipe 31. Then replace the tank cover 28 on the top of the mixing tank 26 using the handle 30. Then turn on the motor 33. The motor 33 drives the protective sleeve 3 connected to the output end to rotate. Then the protective sleeve 3 drives the inner inclined groove 18 to rotate. Then the inclined groove 18 drives the inclined plate 19 to rotate. Then the movable block 20 on one side of the inclined plate 19 rotates. Then the movable block 20 drives the inner clearance groove 21 to rotate. Then the clearance groove 21 drives the movable spring 22 and the protective block 23 to rotate. Block 23 will drive the protective rod 2 to rotate through the protective groove 6, and then the protective rod 2 will drive the stirring rod 1 to rotate, and then the stirring rod 1 will drive the stirring frame 29 to rotate, thereby achieving mixing. After mixing is completed, the discharge valve connected to the discharge pipe 34 is opened, and then the mixed cement can be transported to the subsequent equipment. When the protection threshold is triggered, the stirring rod 1 and the protective rod 2 will not continue to rotate, so the protective groove 6 will not rotate. Then the inner wall of the protective groove 6 will squeeze the protective block 23. Due to the rounded corner structure design of the inner wall of the protective groove 6 and the outer wall of the protective block 23, the protective block 23 will slide out of the protective groove 6 and gradually retract into the relief groove 21, so that the protective block 23 and the inner wall of the relief groove 21 will squeeze the movable spring 22. At this time, the protective block 23 will no longer be stuck in the protective groove 6, so that the motor 33 will drive the protective sleeve 3 to run idle, thereby achieving no-load protection.

[0034] Please see Figures 3-5 As a further implementation of the overall equipment: a plurality of moving rails 35 are fixedly provided on one side of the control sleeve 12, and a moving groove 36 is provided in the moving block 13. The moving block 13 is slidably installed on the outside of the moving rails 35 through the moving groove 36.

[0035] A movable wheel 37 is rotatably mounted on one side of the movable block 13, and the movable wheel 37 is engaged between two adjacent fixed blocks 16.

[0036] The fitting 15 has a mating groove 38 on one side, and the movable block 20 has a mating block 39 fixedly connected to one side, with the mating block 39 sliding in the mating groove 38.

[0037] The outer side of the protective block 23 and the inner edge of the protective groove 6 are both designed with rounded corners.

[0038] More specifically, when the overload protection threshold needs to be adjusted according to actual usage requirements, firstly, the control sleeve 4 is rotated forward. The control sleeve 4 will drive the fixedly connected drive wheel 5 to rotate forward. Then, the drive wheel 5 will drive the meshing driven wheel 9 to rotate in the opposite direction. Then, the driven wheel 9 will drive the screw sleeve 8 to rotate in the opposite direction on the fixed plate 7. Since the screw sleeve 8 and the screw 11 are connected by threads, the screw 11 will drive the sliding sleeve 10 on one side to slide, so that the sliding sleeve 10 no longer limits the outer wall of the sliding wheel 37. Then, the control sleeve 12 is rotated forward. The control sleeve 12 will drive the sliding rail 35 on one side to rotate forward. Then, the sliding rail 35 and the sliding block 13 driven by the sliding groove 36 will rotate forward. Then, the sliding block 13... The moving wheel 37 will move out from between the two fixed blocks 16, and the moving wheel 37 will drive the moving block 13 to slide outward along the moving rail 35 and the moving groove 36. Then the moving block 13 will drive the moving spring 14 to stretch outward. At the same time, the control sleeve 12 will drive the inner spirally opened adapter groove 24 to rotate in the forward direction, so that the adapter block 17 set on the outside of the adapter 15 slides in the adapter groove 24. Since the mating block 39 and the mating groove 38 limit the adapter 15, the adapter 15 will not rotate. Then the adapter 15 will push the moving block 20 on one side to move. Then the moving block 20 will drive the inclined plate 19 on one side to slide along the inclined groove 18. At the same time, the moving block 20 will drive the moving spring 22 and the protective block 23 to move accordingly through the clearance groove 21. Due to the inclined opening of the inclined groove 18, the inclined plate 19 slides in the inclined groove 18 while driving the movable block 20 on one side to converge inward. This causes the movable block 20 to drive the mating block 39 on one side to slide inward along the mating groove 38. The movable block 20 also causes the relief groove 21 to move, shortening the distance between the inner wall of the relief groove 21 and one side of the movable block 20. This causes the movable spring 22 to be compressed, increasing the thrust exerted by the movable spring 22 on the protective block 23. Consequently, the protective block 23 needs to withstand a greater force to detach from the protective groove 6, thus adjusting the protection threshold. When it is necessary to adjust the protective block 23 to detach from the protective groove 6 with only a smaller force, the reverse control sleeve 12 can be used in accordance with the above steps. When adjusted to the mating... After reaching the appropriate protection threshold, stop rotating the control sleeve 12, and allow the moving rail 35 to move the moving block 13 between the corresponding two fixed blocks 16 via the moving groove 36. Then, the moving spring 14 resets and pulls the moving block 13, causing it to slide inward along the moving rail 35 and the moving groove 36. This allows the moving block 13 to drive one side of the moving wheel 37 to engage between the two adjacent fixed blocks 16. Then, rotate the control sleeve 4 in the opposite direction. The control sleeve 4 will drive one side of the driving wheel 5 to rotate in the opposite direction. The driving wheel 5 will then drive the driven wheel 9, which meshes with it, to rotate in the forward direction. The driven wheel 9 will then drive one side of the screw sleeve 8 to rotate in the forward direction on the fixed plate 7. This causes the screw 11 to drive the moving sleeve 10 to slide in the opposite direction. Finally, the moving sleeve 10 slides back to its original position.Then, the inner wall of the movable sleeve 10 limits the outer wall of the movable wheel 37, preventing the movable wheel 37 and the movable block 13 from sliding outwards, thus preventing the control sleeve 12 from rotating unexpectedly. This ensures the stability of the structure with the threshold adjusted, and consequently ensures the stable operation of the stirring process.

[0039] In summary, when using or operating the entire equipment: First, ensure that the discharge valve connected to the discharge pipe 34 is closed. Then, connect the top of the feed pipe 31 to the external pipe. Next, open the tank cover 28 using the handle 30, and add the solid raw material into the mixing tank 26. Water is then transported into the mixing tank 26 through the conveying device connected to the feed pipe 31. Then, close the tank cover 28 back onto the top of the mixing tank 26 using the handle 30. Next, turn on the motor 33. The motor 33 drives the protective sleeve 3 connected to the output end to rotate. The protective sleeve 3 then drives the inner inclined groove 18 to rotate. The inclined groove 18 then drives the inclined plate 19 to rotate. The movable block 20 on one side of the inclined plate 19 then rotates. The movable block 20 then drives the inner clearance groove 21 to rotate. The clearance groove 21 then drives the movable spring 22 and the protective block 23 to rotate. Then, the protective block 23 will drive the protective rod 2 to rotate through the protective groove 6. Then, the protective rod 2 will drive the stirring rod 1 to rotate, and then the stirring rod 1 will drive the stirring frame 29 to rotate, thereby achieving mixing. After mixing is completed, the discharge valve connected to the discharge pipe 34 is opened, and the mixed cement can be transported to the subsequent equipment. When the protection threshold is triggered, the stirring rod 1 and the protective rod 2 will not continue to rotate, so the protective groove 6 will not rotate. Then, the inner wall of the protective groove 6 will squeeze the protective block 23. Due to the rounded corner structure design of the inner wall of the protective groove 6 and the outer wall of the protective block 23, the protective block 23 will slide out of the protective groove 6 and gradually retract into the relief groove 21, so that the protective block 23 and the inner wall of the relief groove 21 will squeeze the movable spring 22. At this time, the protective block 23 will no longer be stuck in the protective groove 6, so that the motor 33 will drive the protective sleeve 3 to run idle, thereby achieving no-load protection.

[0040] When the overload protection threshold needs to be adjusted according to actual usage requirements, firstly, rotate the control sleeve 4 in the forward direction. The control sleeve 4 will drive the drive wheel 5, which is fixedly connected to one side, to rotate in the forward direction. Then, the drive wheel 5 will drive the driven wheel 9, which meshes with it, to rotate in the reverse direction. Then, the driven wheel 9 will drive the screw sleeve 8 to rotate in the reverse direction on the fixed plate 7. Since the screw sleeve 8 and the screw 11 are connected by threads, the screw 11 will drive the sliding sleeve 10 on one side to slide, so that the sliding sleeve 10 no longer limits the outer wall of the sliding wheel 37. Then, rotate the control sleeve 12 in the forward direction. The control sleeve 12 will drive the moving rail 35 on one side to rotate in the forward direction. Then, the moving rail 35 and the moving block 13, which is driven by the moving groove 36, will rotate in the forward direction. Then, the moving block 13 will drive the... One side of the moving wheel 37 moves out from between the two fixed blocks 16, and the moving wheel 37 drives the moving block 13 to slide outward along the moving rail 35 and the moving groove 36. Then the moving block 13 drives the moving spring 14 to stretch outward. At the same time, the control sleeve 12 drives the inner spirally opened adapter groove 24 to rotate in the forward direction, so that the adapter block 17 set on the outside of the adapter 15 slides in the adapter groove 24. Since the mating block 39 and the mating groove 38 limit the adapter 15, the adapter 15 will not rotate. Then the adapter 15 pushes the moving block 20 on one side to move. Then the moving block 20 drives the inclined plate 19 on one side to slide along the inclined groove 18. At the same time, the moving block 20 drives the moving spring 22 and the protective block 23 to move accordingly through the clearance groove 21. Due to the inclined opening of the inclined groove 18, the inclined plate 19 slides in the inclined groove 18 while driving the movable block 20 on one side to converge inward. This causes the movable block 20 to drive the mating block 39 on one side to slide inward along the mating groove 38. The movable block 20 also causes the relief groove 21 to move, shortening the distance between the inner wall of the relief groove 21 and one side of the movable block 20. This causes the movable spring 22 to be compressed, increasing the thrust exerted by the movable spring 22 on the protective block 23. Consequently, the protective block 23 needs to withstand a greater force to detach from the protective groove 6, thus adjusting the protection threshold. When it is necessary to adjust the protective block 23 to detach from the protective groove 6 with only a smaller force, the reverse control sleeve 12 can be adjusted according to the above steps. When the adjustment is appropriate... After reaching the protection threshold, the control sleeve 12 stops rotating, and the moving rail 35 moves the moving block 13 between the two corresponding fixed blocks 16 via the moving groove 36. Then, the moving spring 14 resets and pulls the moving block 13, causing it to slide inward along the moving rail 35 and the moving groove 36. This causes the moving block 13 to drive one side of the moving wheel 37 to engage between the two adjacent fixed blocks 16. Then, the control sleeve 4 is rotated in the opposite direction, causing one side of the driving wheel 5 to rotate in the opposite direction. The driving wheel 5 then drives the driven wheel 9, which meshes with it, to rotate in the forward direction. The driven wheel 9 then drives one side of the screw sleeve 8 to rotate in the forward direction on the fixed plate 7, causing the screw 11 to drive the moving sleeve 10 to slide in the opposite direction. Finally, the moving sleeve 10 slides back to its original position.Then, the inner wall of the movable sleeve 10 limits the outer wall of the movable wheel 37, preventing the movable wheel 37 and the movable block 13 from sliding outwards, thus preventing the control sleeve 12 from rotating unexpectedly. This ensures the stability of the structure with the threshold adjusted, and consequently ensures the stable operation of the stirring process.
