Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This application discloses a desulfurization limestone powder silo level measurement structure, including a support column 1. A collection box 2 is fixedly connected to the top of the support column 1. A servo motor 3 is installed inside the collection box 2. A winding drum 4 is fixedly connected to the output end of the servo motor 3. A pull rope 5 is fixedly connected to the outside of the winding drum 4. Two positioning seats 6 are fixedly connected to the inner wall of the collection box 2. An auxiliary wheel 7 is rotatably connected to the outside of the positioning seats 6. A cleaning mechanism is fixedly connected to the bottom of the collection box 2. The cleaning mechanism includes a connecting cylinder 8. The top of the connecting cylinder 8 is fixedly connected to the lower surface of the collection box 2. A first motor 9 is installed on one side of the connecting cylinder 8. A first gear 10 is fixedly connected to the output end of the first motor 9. A rotating rod 11 is rotatably connected to one side of the connecting cylinder 8. A gear disc 12 is fixedly connected to the outside of the rotating rod 11. A toggle disc 24 is provided at the bottom of the disc 12. The inner wall of the toggle disc 24 is fixedly connected to the outer side of the rotating rod 11. The servo motor 3 drives the winding drum 4 to rotate, and the winding drum 4 drives the pull rope 5 to extend downward. During the descent of the pull rope 5, two auxiliary wheels 7 rotate on the outer side of the positioning seat 6 to guide the outer side of the pull rope 5, so that the descent of the pull rope 5 is sufficiently stable. During the process of hindering the winding of the pull rope 5, the first motor 9 drives the first gear 10 to rotate. The first gear 10 drives the gear disc 12 to mesh and transmit power. The gear disc 12 drives the toggle disc 24 to aggle the pull rope 5 passing inside the connecting drum 8, so that the limestone on the surface of the pull rope 5 can be detached, so as to avoid the limestone affecting the winding and unwinding efficiency of the pull rope 5.
[0024] Reference Figure 6 As shown, a second motor 13 is fixedly connected to one side of the collection box 2, and a second gear 14 is fixedly connected to the output end of the second motor 13. A connecting ring 15 is fixedly connected to the bottom of the collection box 2. A rotating ring 16 with toothed grooves on the outside is rotatably connected inside the connecting ring 15. The top of the rotating ring 16 meshes with the bottom of the second gear 14. Two cleaning arms 17 are fixedly connected to the bottom of the rotating ring 16. The two cleaning arms 17 are symmetrically arranged at the bottom of the rotating ring 16. The second motor 13 drives the second gear 14 to rotate. The second gear 14 meshes with the toothed grooves on the top of the rotating ring 16, so that the rotating ring 16 can rotate inside the connecting ring 15. The rotating ring 16 quickly cleans the outside of the counterweight 22 through the two cleaning arms 17 at the bottom.
[0025] Reference Figure 5 and Figure 4As shown, a counterweight replacement mechanism is provided on the bottom side of the pull rope 5. The counterweight replacement mechanism includes a base block 18, which is fixedly connected to the bottom of the pull rope 5 on the outside. A positioning block 19 is fixedly connected to the outside of the pull rope 5. Two springs 20 are fixedly connected inside the positioning block 19. A locking block 21 is fixedly connected to the top of the springs 20. The outer side of the locking block 21 is slidably connected to the inner wall of the positioning block 19. A counterweight block 22 is slidably connected to the outside of the positioning block 19. Two sliders 23 are fixedly connected to the inner wall of the counterweight block 22. The bottom of the two sliders 23 is engaged with the outer side of the two locking blocks 21. Pulling the counterweight block 22 along the groove on the outside of the positioning block 19 allows the two sliders 23 on the inner wall of the counterweight block 22 to press against the two locking blocks 21 and the springs 20 inside the positioning block 19, so that the counterweight block 22 can be quickly removed from the outside of the positioning block 19.
[0026] The working principle of this utility model is as follows: When measuring the material level in the desulfurization limestone silo, the servo motor 3 is first started to drive the winding drum 4 to rotate. During the rotation of the winding drum 4, the pull rope 5 rotates and extends inside the collection box 2, allowing the pull rope 5 to move the positioning block 19 and the counterweight block 22 at the bottom of the silo downwards from the top. When the counterweight block 22 falls to the top of the limestone inside the silo, the length of the extended pull rope 5 is detected by the external controller, thereby determining the material level of the desulfurization limestone in the silo. After the measurement is completed, the servo motor 3 drives the positioning block 19 and the counterweight block 22 upwards through the winding drum 4 and the pull rope 5. The pull rope 5 is wound up to the top. When the cord is inside the spool 4, it will pass through the inside of the connecting spool 8. At this time, the first motor 9 drives the first gear 10 to mesh with the gear plate 12. The gear plate 12 drives the actuating plate 24 to rotate rapidly through the rotating rod 11. During the rotation, the actuating plate 24 will actuate the pull rope 5 passing through the inside of the connecting spool 8, cleaning the limestone adsorbed on the outside of the pull rope 5. After that, when the top of the positioning block 19 moves to the inside of the bottom block 18, the second motor 13 drives the second gear 14 to mesh with the rotating ring 16, so that the rotating ring 16 can drive the two cleaning arms 17 to rotate at the temporal part of the connecting ring 15. The two cleaning arms 17 clean the outside of the counterweight block 22.
[0027] When it is necessary to replace the counterweight 22, move the counterweight 22 to one side of the positioning block 19 so that the two sliders 23 press against the two locking blocks 21 and the spring 20 inside the positioning block 19, so that the two locking blocks 21 are pressed into the interior of the positioning block 19, thereby the counterweight 22 can be quickly removed from one side of the positioning block 19 for subsequent replacement and installation.
