Description

Technical Field

[0001] This utility model relates to the field of solid waste crushing and sorting technology, specifically to an active belt pulley diameter adjustment mechanism for a side agitator of an absorption tower. Background Technology

[0002] The agitator on the absorber side is used to stir the slurry in the slurry tank at low speed, keeping the solids in the slurry in a suspended state. These suspended solids continuously diffuse and, together with oxidizing air, enhance the oxidation reaction of the slurry. The agitator shaft is solid, single-rod, and belt-driven; it adopts a mechanical seal system and radial bearing design; the agitator shell is connected to the absorber wall via flanges; the motor is fixed to the upper support of the agitator with long bolts; the operation mode is continuous operation.

[0003] For example, a new absorber side agitator for boiler desulfurization equipment, with application number CN202020235637.X and authorization announcement date of 20201208, includes a tower sidewall. A guide rail is fixedly installed on one side of the tower sidewall, and a slide is installed on the guide rail. The slide and the guide rail are slidably connected. A lifting frame is fixedly installed on one side of the slide, and two cylinders are installed on one side of the lifting frame. Rubber balls are installed at the output ends of the cylinders. A rack is installed on the side of the tower sidewall away from the cylinders. A first gear and the rack mesh with each other. A mixing tank is installed at the top of the lifting frame, and a gear disk is provided at the bottom of the mixing tank. A first rotating rod is fixedly installed in the middle of the gear disk, and a bushing matching the first rotating rod is provided at the top of the lifting frame. A reduction motor is installed in the middle of the top of the lifting frame, and a second gear is installed at the output end of the reduction motor. The second gear and the gear disk mesh with each other. This utility model provides a second gear and a gear disk at the bottom of the mixing tank, which facilitates automatic unloading.

[0004] During the operation of the absorption tower, due to the slow speed of the agitator, slurry accumulation occurs inside the tower, clogging the inlet filter of the circulating pump, reducing the output of the circulating pump, increasing cavitation, and slowing down the oxidation reaction of the slurry, thus affecting the quality of the slurry. Although this problem can be solved by increasing the motor speed, this solution is wasteful of electricity and can damage the transmission mechanism. Therefore, it is urgent to design an active belt pulley diameter adjustment mechanism for the agitator on the absorption tower side to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an active belt pulley diameter adjustment mechanism for the agitator on the side of the absorption tower, so as to solve the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An active belt pulley diameter adjustment mechanism for a side agitator in an absorption tower includes an adjustment component, a large pulley, and a belt. The belt is wound around the outside of the large pulley, and the other end of the belt is wound around the adjustment component.

[0008] The adjustment assembly includes a support assembly, and a pulley assembly is mounted on the center of one outer wall of the support assembly via a bearing.

[0009] The support assembly includes a support frame, and a drive motor is bolted to the center of one outer wall of the support frame, and the output end of the drive motor is provided with a mounting shaft.

[0010] The pulley assembly includes a cross-shaped fixing bracket, which is bolted to one end of the mounting shaft. Four mounting slots are provided on one outer wall of the cross-shaped fixing bracket, and mounting brackets are slidably inserted into the mounting slots. Small pulleys are mounted inside the mounting brackets via bearings, and the small pulleys are connected to the belt in a transmission manner. A driven gear is mounted on one end of the small pulley via a flat key. A lifting cylinder is bolted inside the mounting slot, and the output end of the lifting cylinder is fixedly connected to the mounting bracket.

[0011] Furthermore, a drive gear is mounted on one side of the outer wall of the support frame via a bearing, and the drive gear meshes with the driven gear.

[0012] Furthermore, a second drive motor is bolted to one side of the outer wall of the support frame, and the output end of the second drive motor is fixedly connected to the drive gear via a flat key.

[0013] Furthermore, two fixing seats are bolted to one side of the outer wall of the support frame, and two guide pulleys are mounted on one side of the outer wall of the support frame via bearings, with the belt passing through the guide pulleys.

[0014] Furthermore, two slide rods are inserted between the two fixed seats, and two limiting racks are slidably connected between the two slide rods, with the limiting racks meshing with the ratchet.

[0015] Furthermore, a pushing cylinder is bolted to the center of the outer wall on one side of the fixed seat, and the output end of the pushing cylinder is fixedly connected to the limiting rack via bolts.

[0016] In the above technical solution, the active belt pulley diameter adjustment mechanism for the absorber side agitator provided by this utility model has the following advantages:

[0017] (1) When it is necessary to adjust the stirring speed of the agitator in the absorption tower by setting the drive motor 1, cross fixing frame, mounting frame and small pulley, the drive motor 1 can be started. Then the drive motor 1 will rotate with the mounting shaft. The rotating mounting shaft will move with the cross fixing frame, so that the position of the small pulley on the cross fixing frame changes, so that the small pulleys with different rims contact the belt, thereby realizing the adjustment of the transmission ratio of the mechanism. This facilitates the speed increase of the pulley transmission structure, so that the speed of the agitator connected to the connecting shaft changes. This is beneficial to reduce the precipitation of suspended matter in the slurry zone of the absorption tower, strengthen the oxidation reaction of the slurry, and improve the slurry quality. At the same time, the speed reduction can also be achieved by adjustment to meet the processing needs of different absorption towers.

[0018] (2) After the pulley assembly is adjusted by the set push cylinder, limit rack and ratchet, the push cylinder can be started. The push cylinder will slide on the slide bar with the limit rack. The two limit racks will lock the ratchet, which can ensure the stability of the cross fixing frame after adjustment and avoid the problem of transmission failure caused by the instability of the cross fixing frame when the belt structure is driven.

[0019] (3) When adjusting the transmission ratio of the mechanism by rotating the cross-fixed frame through the set lifting cylinder and mounting frame, the lifting cylinder can be started to make the mounting frame slide inside the mounting groove, so that the mounting frame moves with the small pulley, so that the small pulleys with different rims can support the belt, ensure the belt tension, and meet the requirement that the mechanism can continue to transmit after adjustment.

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-6 As shown in the embodiment of this utility model, the active belt pulley diameter adjustment mechanism for the absorber side stirrer includes an adjustment component 1, a large pulley 2 and a belt 3. The belt 3 is characterized in that the belt 3 is wound around the outside of the large pulley 2, and the other end of the belt 3 is wound around the adjustment component 1.

[0031] Adjustment component 1 includes support component 5, and a pulley component 6 is mounted on the center of the outer wall of one side of support component 5 via a bearing;

[0032] The support assembly 5 includes a support frame 7. A drive motor 9 is bolted to the center of one side of the outer wall of the support frame 7, and the output end of the drive motor 9 is provided with a mounting shaft 16.

[0033] The pulley assembly 6 includes a cross-shaped fixing bracket 18, which is bolted to one end of the mounting shaft 16. Four mounting slots 22 are provided on one outer wall of the cross-shaped fixing bracket 18, and mounting brackets 19 are slidably inserted into the mounting slots 22. Small pulleys 20 are mounted inside the mounting brackets 19 via bearings. The small pulleys 20 are connected to the belt 3 in a transmission manner. A driven gear 21 is mounted on one end of the small pulleys 20 via a flat key. A lifting cylinder 23 is bolted inside the mounting slots 22, and the output end of the lifting cylinder 23 is fixedly connected to the mounting bracket 19.

[0034] Specifically, in this embodiment, it includes an adjustment component 1, a large pulley 2, and a belt 3, characterized in that the belt 3 is wound around the outside of the belt 3, and the other end of the belt 3 is wound around the adjustment component 1;

[0035] Adjustment component 1 includes support component 5, and a pulley component 6 is mounted on the center of the outer wall of one side of support component 5 via a bearing;

[0036] The support assembly 5 includes a support frame 7. A drive motor 9 is bolted to the center of the outer wall of one side of the support frame 7. The drive motor 9 is preferably a 57BYGH650-23, and the output end of the drive motor 9 is provided with a mounting shaft 16.

[0037] The pulley assembly 6 includes a cross-shaped fixing bracket 18. When the drive motor 9 is started, it rotates the mounting shaft 16, which in turn moves the cross-shaped fixing bracket 18, changing the position of the small pulleys 20 on the cross-shaped fixing bracket 18. This causes the small pulleys 20 with different rim diameters at other positions to contact the belt 3. The cross-shaped fixing bracket 18 is bolted to one end of the mounting shaft 16. Four mounting slots 22 are formed on one outer wall of the cross-shaped fixing bracket 18, and mounting brackets 19 are slidably inserted into the slots 22. Small pulleys 20 are mounted inside the mounting brackets 19 via bearings. There are four small pulleys 20, each with a different rim diameter, which can meet the requirements for increasing... For the purpose of speeding up or slowing down, the small pulley 20 and the belt 3 are connected by a transmission. One end of the small pulley 20 is equipped with a driven gear 21 through a flat key. A lifting cylinder 23 is installed inside the mounting groove 22 by bolts. The preferred model of the lifting cylinder 23 is SC20*50. Controlling the corresponding lifting cylinder 23 to start will cause the lifting cylinder 23 to move the mounting frame 19. The mounting frame 19 will slide inside the mounting groove 22 and move the small pulley 20, so that the small pulleys 20 with different rims can support the belt 3, ensuring the tension of the belt 3 and meeting the requirement that the mechanism can continue to transmit after adjustment. The output end of the lifting cylinder 23 is fixedly connected to the mounting frame 19.

[0038] The active belt pulley diameter adjustment mechanism for the agitator on the absorber side of the present invention allows for speed adjustment of the agitator at the absorber tower. When speed adjustment is required, the drive motor 9 can be started, causing the mounting shaft 16 to rotate. The rotating mounting shaft 16 then moves the cross-shaped fixing frame 18, changing the position of the small pulleys 20 on the cross-shaped fixing frame 18. This allows the small pulleys 20 at different rims to contact the belt 3, thus adjusting the transmission ratio of the mechanism. This facilitates speed increase of the belt drive structure, changing the speed of the agitator connected to the connecting shaft 4. This helps reduce suspended solids sedimentation in the absorber slurry zone, enhances the oxidation reaction of the slurry, and improves slurry quality. Simultaneously, speed reduction can also be achieved through adjustment to meet the processing needs of different absorber towers.

[0039] In one embodiment provided by this utility model, such as Figure 4-5 As shown, a drive gear 11 is mounted on one side of the outer wall of the support frame 7 via bearings, and the drive gear 11 meshes with the driven gear 21. A second drive motor 10 is bolted to one side of the outer wall of the support frame 7. The preferred model of the second drive motor 10 is 57BYGH650-23. During transmission, the second drive motor 10 can be started, and the started drive motor 10 will rotate the drive gear 11. The rotating drive gear 11 will rotate the driven gear 21, and then the driven gear 21 will rotate the small pulley 20. The rotating small pulley 20 will rotate the large pulley 2 via the belt 3, so that the connecting shaft 4 can rotate the agitator to achieve the purpose of stirring the absorption tower. The output end of the second drive motor 10 is fixedly connected to the drive gear 11 via a flat key. Two fixed seats 12 are bolted to one side of the outer wall of the support frame 7. Two guide pulleys 8 are installed through bearings to guide the position of the belt 3. The belt 3 passes through the guide pulleys 8. Two slide rods 14 are inserted between the two fixed seats 12, and two limiting racks 15 are slidably connected between the two slide rods 14. The limiting racks 15 mesh with the ratchet 17. A push cylinder 13 is bolted to the center of the outer wall of one side of the fixed seat 12. The preferred model of the push cylinder 13 is SC20*50. When the push cylinder 13 is started, it will slide the limiting racks 15 on the slide rods 14. The two limiting racks 15 will lock the ratchet 17, thereby limiting the ratchet 17. This ensures the stability of the cross fixing frame 18 after adjustment and avoids the problem of transmission failure due to the instability of the cross fixing frame 18 during belt transmission. The output end of the push cylinder 13 is fixedly connected to the limiting racks 15 by bolts. Example 1

[0040] An active belt pulley diameter adjustment mechanism for a side agitator in an absorption tower includes an adjustment component 1, a large pulley 2, and a belt 3. The belt 3 is wound around the outside of the large pulley 2, with the other end of the belt 3 wound around the adjustment component 1. The adjustment component 1 includes a support component 5, with a pulley assembly 6 mounted on the center of one side of the outer wall of the support component 5 via a bearing. The support component 5 includes a support frame 7, with a drive motor 9 (preferably model 57BYGH650-23) bolted to the center of one side of the outer wall of the support frame 7. The output end of the drive motor 9 has a mounting shaft 16. The pulley assembly 6 includes a cross-shaped fixing bracket 18. When the drive motor 9 is started, it rotates the mounting shaft 16, causing the cross-shaped fixing bracket 18 to move, changing the position of the small pulleys 20 on the cross-shaped fixing bracket 18. This causes the small pulleys 20 at different rim positions to contact the belt 3. The cross-shaped fixing bracket 18 is bolted to the mounting shaft 18. At one end of the cross-shaped fixing bracket 18, four mounting slots 22 are provided on the outer wall of one side, and mounting brackets 19 are slidably inserted into the mounting slots 22. Small pulleys 20 are mounted inside the mounting brackets 19 via bearings. There are four small pulleys 20, each with a different rim diameter, which can meet the purpose of speeding up or slowing down. The small pulleys 20 are connected to the belt 3 in a transmission connection. A driven gear 21 is mounted on one end of the small pulley 20 via a flat key. A lifting cylinder 23 is bolted inside the mounting slots 22. The preferred model of the lifting cylinder 23 is SC20*50. Controlling the corresponding lifting cylinder 23 to start will cause the lifting cylinder 23 to move the mounting bracket 19. The mounting bracket 19 will slide inside the mounting slots 22 and move the small pulleys 20, so that the small pulleys 20 with different rims can support the belt 3, ensuring the tension of the belt 3 and meeting the requirement that the mechanism can continue to transmit after adjustment. The output end of the lifting cylinder 23 is fixedly connected to the mounting bracket 19. Example 2

[0041] This embodiment further defines the features of Embodiment 1. A drive gear 11 is mounted on one side of the outer wall of the support frame 7 via bearings, and the drive gear 11 meshes with the driven gear 21. A second drive motor 10 is bolted to one side of the outer wall of the support frame 7. The preferred model of the second drive motor 10 is 57BYGH650-23. During operation, the second drive motor 10 can be started, causing the drive gear 11 to rotate. The rotating drive gear 11 then rotates the driven gear 21, which in turn rotates the small pulley 20. The small pulley 20, via the belt 3, rotates the large pulley 2, thus enabling the connecting shaft 4 to rotate the agitator, achieving the purpose of stirring the absorption tower. The output end of the second drive motor 10 is fixedly connected to the drive gear 11 via a key. Two fixed seats 12 are bolted to one side of the outer wall of the support frame 7. Two guide pulleys 8 are mounted on one side of the outer wall of the support frame 7 via bearings. The guide pulleys 8 can guide the position of the belt 3. The belt 3 passes through the guide pulleys 8. Two slide rods 14 are inserted between the two fixed seats 12, and two limiting racks 15 are slidably connected between the two slide rods 14. The limiting racks 15 mesh with the ratchet 17. A push cylinder 13 is bolted to the center of one side of the outer wall of the fixed seat 12. The preferred model of the push cylinder 13 is SC20*50. When the push cylinder 13 is started, the push cylinder 13 will slide on the slide rods 14 with the limiting racks 15. The two limiting racks 15 will lock the ratchet 17, thereby limiting the ratchet 17. This can ensure the stability of the cross fixed frame 18 after adjustment and avoid the problem of transmission failure due to the instability of the cross fixed frame 18 during the transmission of the belt structure. The output end of the push cylinder 13 is fixedly connected to the limiting racks 15 via bolts.

[0042] Working principle: When it is necessary to adjust the speed of the agitator at the absorption tower, the drive motor 9 can be started. The drive motor 9 will then rotate the mounting shaft 16, which in turn will move the cross-shaped fixing bracket 18, causing the position of the small pulleys 20 on the cross-shaped fixing bracket 18 to change. This allows the small pulleys 20 at different rims to contact the belt 3. Simultaneously, the driven gear 21 will mesh with the driving gear 11. When the corresponding transmission ratio is adjusted, the corresponding lifting cylinder 23 can be activated. The lifting cylinder 23 will move the mounting bracket 19, which will slide inside the mounting groove 22. The mounting bracket 19 will move the small pulleys 20, ensuring that the small pulleys 20 at different rims support the belt 3, guaranteeing the belt tension. After adjustment, the mechanism can... To continue transmission, the push cylinder 13 is activated. The push cylinder 13 will slide on the slide bar 14 with the limiting rack 15. The two limiting racks 15 will lock the ratchet 17, thus limiting the ratchet 17 and ensuring the stability of the cross fixing frame 18 after adjustment. This avoids transmission failure caused by instability of the cross fixing frame 18 during belt transmission. In subsequent transmission, the drive motor 2 10 can be activated. The activated drive motor 2 10 will drive the drive gear 11 to rotate. The rotating drive gear 11 will drive the driven gear 21 to rotate. The driven gear 21 will then drive the small pulley 20 to rotate. The rotating small pulley 20 will drive the large pulley 2 through the belt 3, so that the connecting shaft 4 can drive the agitator to rotate, thus satisfying the purpose of stirring the absorption tower.
