Description

A feeding device for wet carbide slag in cement production Technical Field

[0001] This invention relates to the field of calcium carbide slag conveying technology, and in particular to a feeding device for wet calcium carbide slag in cement production. Background Technology

[0002] As an alternative raw material for cement production, wet carbide slag can partially replace limestone in providing calcium oxide, reducing raw material costs and disposing of industrial waste. Its active ingredients can promote clinker mineral formation, improve cement stability, and achieve a circular economy. When transporting wet carbide slag, it is transported in ton bags. Therefore, a feeding device is installed on the cement production line, designed for automatic feeding of ton bags. It adopts a modular structure, integrating hoisting, bag breaking, and conveying. During operation, the ton bag is hoisted to the equipment inlet by an electric lifter. After being fixed by an automatic bag clamping device, the built-in vibrating bag breaking knife precisely cuts the bottom of the ton bag, and the wet carbide slag falls at a uniform speed in conjunction with the frequency conversion vibration platform.

[0003] When cement production uses ton bag unloading and feeding machines to process wet carbide slag, electric lifters are relied upon to complete the hoisting and lifting of the ton bags. The existing lifters are fixed directly above a single unloading machine via columns or top rails, forming a rigid one-to-one correspondence. When a company expands its production and needs to add a second unloading machine, it can only purchase a complete set of lifting devices, and cannot share the original equipment. The investment and land occupation double accordingly. The more prominent contradiction lies in the operating cycle. The unloading of wet carbide slag is slow, and the lifter must remain at its original position to wait for the ton bags to be emptied. During this period, it cannot be moved to adjacent equipment to perform bag lifting tasks, resulting in long-term idleness and low equipment utilization, which has become a bottleneck restricting continuous material supply.

[0004] Therefore, a feeding device for wet carbide slag in cement production is proposed to solve the above problems. Summary of the Invention

[0028] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0030] In practical use, it was found that the existing lifting device is fixed directly above a single unpacking machine by a column or top rail, forming a rigid correspondence of one machine and one lifting device. When the enterprise expands its production and needs to add a second unpacking machine, it can only purchase a complete set of lifting devices, and cannot share the original equipment. The investment and land occupation double accordingly. The more prominent contradiction lies in the working rhythm. The unloading of wet carbide slag is slow, and the lifting device must stay at the original position to wait for the ton bag to be emptied. During this period, it cannot be moved to the adjacent equipment to perform bag lifting tasks, resulting in long-term idle time and low equipment utilization, which has become a bottleneck restricting continuous material supply. In order to solve the above problems, the following structure was invented.

[0031] As shown in Figures 1-9, a feeding device for wet carbide slag in cement production includes a feeding frame 1 and an electric lifter 2. The feeding frame 1 is equipped with a guide rail 3 fixed to the top of a wall. An automatically moving trolley 4 is mounted on the guide rail 3, with its own drive wheels clamping the guide rail 3. A motor and reducer drive the wheel assembly to rotate, moving horizontally along the guide rail 3. An encoder provides real-time position feedback, and a PLC controls start / stop and acceleration / deceleration, achieving automatic alignment and feeding of ton bags. The electric lifter 2 is fixedly connected to the bottom of the trolley 4. The lifting end of the electric lifter 2... The lifting component 5 is fixedly connected. The motor on the electric lifting device 2 drives the drum to wind and unwind the wire rope via the reducer, driving the lifting component 5 to move up and down. At the same time, the brake and limit switch work together to ensure precise start and stop. It can vertically lift ton bags or heavy objects. The unloading rack 1 is equipped with an unloading platform 6 for placing and shaking the ton bags. The unloading platform 6 is used to carry the ton bags and has a built-in pneumatic bag shaking mechanism. By driving the carrying platform to shake, it causes the wet carbide slag to fall continuously. The vibration frequency and amplitude can be adjusted by frequency conversion. It works with the weighing sensor to achieve quantitative unloading.

[0032] Below the unloading platform 6 is a conveying mechanism 7 for conveying wet carbide slag. The conveying mechanism 7 mainly adopts a screw conveyor, which is a mature technology in the existing technology and will not be described in detail here. Below the lifting component 5 is a ton bag frame 8 for hooking the ton bag. The top of the ton bag frame 8 is fixedly connected to a fixed frame 9. The bottom of the lifting component 5 is fixedly connected to a rod 10 for inserting into the fixed frame 9. The fixed frame 9 is provided with a locking mechanism for locking the position of the rod 10, and also with a positioning mechanism for automatically positioning and releasing the position of the rod 10. The unloading rack 1 is provided with a transverse frame 11. The transverse frame 11 is provided with a transfer mechanism for positioning and moving the lifting component 5 to another unloading rack 1.

[0033] When unloading wet carbide slag, the ton bag is first moved to the unloading rack 1 by a forklift. Then, the overhead crane 4 is controlled to move the electric lifting device 2 above the ton bag, and at the same time, the lifting component 5 and the ton bag frame 8 are moved above the ton bag. The electric lifting device 2 can then be controlled to lower the lifting component 5, so that the ton bag frame 8 moves onto the ton bag. The hook bag of the ton bag is hooked onto the ton bag frame 8. The electric lifting device 2 can then be controlled to rise, driving the ton bag to rise. After reaching the designated height, the overhead crane 4 is controlled to move and transfer the ton bag into the unloading rack 1. The electric lifting device 2 can then be controlled to lower and place the ton bag on the unloading platform 6 for unloading.

[0034] The locking mechanism includes a locking plate 12, which is provided in two pairs. The inner ends of the fixed frame 9 are provided with horizontal grooves 13. A pair of sliding frames 14 are slidably connected to the inner side of each horizontal groove 13. The locking plates 12 are slidably connected to the inner side of each sliding frame 14. A pair of upper springs 15 are fixedly connected between the side wall of the locking plate 12 and the inner side of the sliding frame 14. Several locking grooves 16 are provided at equal intervals on both sides of the outer wall of the insertion rod 10. The tops of the locking grooves 16 are inclined. The tops of the locking plates 12 on the side closer to the insertion rod 10 are also inclined.

[0035] A pair of straight grooves 36 are provided through the horizontal groove 13 on the side away from each other. A straight rod 17 is fixedly connected to the side of the sliding frame 14 away from the insert rod 10, and the straight rod 17 is inserted into the inner side of the corresponding straight groove 36. A pair of lower springs 18 are fixedly connected between the inner side of the horizontal groove 13 and the side wall of the sliding frame 14.

[0036] The positioning mechanism includes an L-shaped block 19, and a pair of L-shaped blocks 19 are provided. The L-shaped blocks 19 are located on both sides of the outer wall of the fixed frame 9. L-shaped electromagnets 20 are fixedly connected to both ends of the L-shaped blocks 19 on the side closest to each other. The inner side of the L-shaped electromagnets 20 is engaged with the corner of the outer wall of the fixed frame 9. A rear frame 21 is fixedly connected to the rear side of the unloading rack 1. A pair of rear rods 22 are slidably connected to the inner side of the rear frame 21. The L-shaped blocks 19 are fixedly connected to the front end of the rear rods 22. A moving mechanism for driving the rear rods 22 is provided on the rear frame 21. A side groove is opened through the side wall of the L-shaped block 19. A moving plate 24 is slidably connected to the inner side of the side groove. An unlocking plate 25 is fixedly connected to the side of the moving plate 24 near the insertion rod 10. The unlocking plate 25 is located above the straight rod 17 and is inclined on both sides.

[0037] The top of each L-shaped block 19 is fixedly connected to an upper electric telescopic cylinder 26. The output end of the upper electric telescopic cylinder 26 passes through the side groove and is fixedly connected to the top of the moving plate 24. The top of the L-shaped block 19 is provided with a central groove 23. The central groove 23 is provided to avoid obstructing the downward sliding of the unlocking plate 25.

[0038] The moving mechanism includes a moving motor 27, a bidirectional lead screw 28 rotatably connected to the inner side of the rear frame 21, the moving motor 27 is fixedly connected to the side wall of the unloading frame 1, the side end of the bidirectional lead screw 28 passes through the outer wall of the unloading frame 1 and is fixedly connected to the output end of the moving motor 27, the bidirectional lead screw 28 is threadedly connected to the inner side wall of the rear rod 22, and the two rear rods 22 are respectively set on the two threads of the bidirectional lead screw 28;

[0039] The L-shaped electromagnet 20 is inclined at the corner relative to the fixed frame 9. The fixed frame 9 is made of iron, and the four corners of the outer wall of the fixed frame 9 are made of smooth arc surface.

[0040] The transfer mechanism includes a lower electric telescopic cylinder 29, a pair of side supports 30 fixedly connected to the top of the unloading rack 1, a transverse frame 11 longitudinally slidably connected to the side wall of the side supports 30, a top block 31 slidably connected to the inner side of the transverse frame 11, an inclined groove is opened through the side wall of the top block 31, the lower electric telescopic cylinder 29 is fixedly connected to the inclined surface of the inclined groove, the output end of the lower electric telescopic cylinder 29 passes through the side wall of the top block 31 and is fixedly connected to an L-shaped top electromagnet 32, the lifting component 5 is made of iron, a top electric telescopic cylinder 33 is fixedly connected to the top of the unloading rack 1, and the output end of the top electric telescopic cylinder 33 is fixedly connected to the top of the transverse frame 11;

[0041] A threaded rod 34 is rotatably connected to the inner side of the transverse frame 11, and a drive motor 35 is fixedly connected to the front side of the transverse frame 11. The output end of the drive motor 35 passes through the inner side of the transverse frame 11 and is fixedly connected to the side wall of the threaded rod 34. The threaded rod 34 is threadedly connected to the inner side wall of the top block 31.

[0042] When it is necessary to expand the unloading rack 1, first install the new unloading rack 1 next to the old unloading rack 1, and connect the new guide rail 3 with the old guide rail 3 to ensure the normal movement of the overhead crane 4. Then, during the process of lifting the ton bag to the unloading platform 6 for unloading, the movable motor 27 can be started to drive the bidirectional lead screw 28 to rotate, which in turn drives the two threaded rear rods 22 to move towards the center, and at the same time drives the L-shaped block 19 and the L-shaped electromagnet 20 to move towards the center. When the L-shaped electromagnet 20 moves to the side of the fixed frame 9, if the fixed frame 9 is in an offset state, The inclined surface at the corner of the L-shaped electromagnet 20 will press against the arc surface of the fixing frame 9, thereby pressing the fixing frame 9 into the inside of the L-shaped electromagnet 20 until the four corners of the fixing frame 9 are locked inside the four L-shaped electromagnets 20, thus completing the position limitation of the fixing frame 9. (It should be noted that since the ton bag is placed on the unloading platform 6 and cannot be moved, but the hook rope on the ton bag is in a slack state, the fixing frame 9 can drive the ton bag frame 8 and the hook rope on the ton bag to move during the pressing, thereby ensuring that the fixing frame 9 is accurately clamped between the four L-shaped electromagnets 20.)

[0043] Then, the L-shaped electromagnet 20 is energized to attract and fix the fixing frame 9 (it should be noted that since the ton bag is placed on the unloading platform 6, the rear rod 22 is not supported by the ton bag). Then, the upper electric telescopic cylinder 26 is started to drive the moving plate 24 to move downward, and at the same time, the unlocking plate 25 is moved downward. During this process, since the straight rod 17 can only slide laterally inside the straight groove 36, under the pressure of the inclined surface of the unlocking plate 25, the straight rod 17 will be gradually pushed to slide to both sides in the straight groove 36, while the sliding frame 14 and the locking plate 12 will slide to both sides and gradually compress the lower spring 18, which will then drive the locking plate 12 to gradually move out of the locking groove 16, releasing the locking restriction between the insertion rod 10 and the fixing frame 9.

[0044] Then, the lower electric telescopic cylinder 29 can be controlled to start and drive the top electromagnet 32 ​​to move diagonally downwards. Subsequently, the inner side of the top electromagnet 32 ​​is locked onto the outer wall of the lifting component 5. (It should be noted that since the size of the ton bag is fixed, the position of the lifting component 5 controlled by the electric lifting device 2 is the same each time. When the position of the fixing frame 9 is limited by the position of the L-shaped electromagnet 20, the top electromagnet 32 ​​can accurately adhere to the outer wall of the lifting component 5 under the drive of the lower electric telescopic cylinder 29.) Then, the top electromagnet 32 ​​is energized to adhere and fix the lifting component 5, and then the top electric telescopic cylinder 33 is started. The horizontal moving frame 11 is moved upward on the side support 30. At the same time, the lower electric telescopic cylinder 29 drives the top electromagnet 32 ​​to move upward, thereby driving the lifting component 5 and the insertion rod 10 to move upward, so that the insertion rod 10 is pulled out from the fixed frame 9. During this process, the rope of the electric lifting device 2 will be folded. After the insertion rod 10 is pulled out, the drive motor 35 can be started to drive the threaded rod 34 to rotate, which in turn drives the threaded top block 31 to slide in the horizontal moving frame 11. At the same time, the trolley 4 is started to move on the guide rail 3 and drive the electric lifting device 2 to move to another unloading rack 1.

[0045] Subsequently, when the insertion rod 10 moves to the fixed frame 9 on another unloading rack 1 (at this time, the other fixed frame 9 is in a state of being attracted and fixed by another L-shaped electromagnet 20, and the positions of the two fixed frames 9 are fixed, so as to ensure the accurate insertion and docking of the insertion rod 10), the top electric telescopic cylinder 33 can be controlled to start and drive the horizontal moving frame 11 to move down and reset, thereby inserting the insertion rod 10 into the other fixed frame 9. During this process, when the bottom of the insertion rod 10 moves to the locking plate 12, the bottom of the insertion rod 10 will press against the inclined surface of the locking plate 12, thereby causing the locking plate 12 to slide into the sliding frame 14, while compressing the upper spring 15. Then, when the locking groove 16 moves to the side of the locking plate 12, it will release the compression on the locking plate 12, and then push it back to reset under the elastic force of the upper spring 15, thereby causing the locking plate 12 to insert into the corresponding locking groove 16. Then, as the insertion rod 10 moves down, the locking plate 10 moves into the other fixed frame 9. As the 0 continues to move downwards, the inclined surface at the top of the locking groove 16 will press against the inclined surface at the top of the locking plate 12, pushing the locking plate 12 further into the sliding frame 14, compressing the upper spring 15. Then, another locking groove 16 moves to the side of the locking plate 12, and the above operation is repeated until the insertion rod 10 is fully inserted. At this time, the locking plate 12 is inserted into the corresponding locking groove 16, thereby locking the position of the insertion rod 10. Then, the power supply of the other L-shaped electromagnet 20 can be disconnected, and the moving motor 27 can be reversed to drive the L-shaped block 19 and the L-shaped electromagnet 20 to reset. This can control the electric lifting device 2 and the crane 4 to start. During the unloading of another ton bag, the ton bag next to the other unloading rack 1 is hoisted. When the other ton bag is hoisted to the unloading platform 6 for unloading, the above operation can be repeated to reset the lifting device 5. The reset is repeated, and it can be used back and forth between the two unloading racks 1.

[0046] In summary, through the design of the above structure, during the unloading and unloading process of the ton bags storing wet carbide slag on the unloading platform 6, the positions of the fixing frame 9 and the insertion rod 10 are automatically positioned first. When the position of the fixing frame 9 deviates, the fixing frame 9 is automatically squeezed and positioned in the designated position for unlocking, so as to avoid affecting the normal operation of the subsequent transfer mechanism. Then, the connection between the electric lifter 2 and the ton bag frame 8 is automatically released, and the lifting part 5 of the electric lifter 2 is positioned and moved to the ton bag frame 8 on another unloading rack 1. At the same time, the positions of the two are locked. Thus, during the unloading process of one ton bag, the ton bag next to the other unloading rack 1 can be lifted for unloading, realizing two uses in one machine and reducing the expansion cost of the equipment.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.

[0048] Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
