Description

Technical Field

[0001] This utility model relates to the field of barite powder production technology, specifically to a shock-absorbing device for barite powder processing. Background Technology

[0002] Barite powder's main component is barium sulfate, which plays an important role in the oil and gas drilling industry. Adding barite powder to drilling mud can significantly increase the mud's density. High-density mud can prevent blowouts and improve drilling efficiency. In the process of barite powder production, large pieces of raw ore usually need to be crushed into smaller particles, and crushers are commonly used crushers. However, existing crushers have problems such as those described in the authorization announcement number CN219605932U "A Shock-absorbing Base for a Crusher". When crushing materials, the crusher will generate considerable vibration due to the impact of the motor drive and the internal materials. The crusher is prone to damage to internal parts due to prolonged vibration, which will reduce the life of the crusher. Utility Model Content

[0003] This invention addresses the problem that vibrations generated during material crushing can affect the service life of a crusher by providing a vibration damping device for barite powder processing, which can reduce the vibration amplitude of the crusher.

[0004] To solve the above problems, the technical solution of this utility model is: A vibration damping device for barite powder processing includes a crusher mounted on a vibration damping base. The vibration damping base includes a top plate and a bottom plate elastically connected. It also includes energy-consuming components arranged in a ring between the top and bottom plates. Each energy-consuming component includes a housing and a rotating rod. The housing is fixed to the top surface of the bottom plate, and a partition plate is fixed inside the housing away from the center of the bottom plate. The outer end of the rotating rod rotatably passes through the partition plate and is rotatably connected to a friction plate. The inner end of the rotating rod is rotatably connected to the inner end of the housing. The first friction plate is in frictional contact with a second friction plate fixed to the inner surface of the outer end of the housing. A spiral groove is formed on the rotating rod, and a drive column is slidably fitted to the outside of the rotating rod. A drive rod with its end extending into the spiral groove is fixed on the drive column. The drive column is connected to the top plate via a hinge. When the top plate moves downwards or upwards, the drive column is driven away from or near the center of the bottom plate via the hinge. When the drive column moves away from the center of the bottom plate and drives the rotating rod to rotate, the first friction plate rotates with the rotating rod.

[0005] Furthermore, the outer end of the rotating rod is rotatably connected to the friction plate via a one-way bearing, and the inner end is rotatably connected to the inner end of the housing via a two-way bearing; the driving column is slidably sleeved on the corresponding rotating rod through a through hole in the middle, and the driving rod is a cylinder with its end in sliding contact with the spiral groove, and the outer end of the driving column is connected to the partition plate inside the housing via a buffer spring.

[0006] Furthermore, the friction plate has a mounting hole recessed on one side of the corresponding rotating rod, and the inner ring of the one-way bearing is fixedly connected to the outer wall of the rotating rod, while the outer ring is fixedly connected to the circumferential surface of the mounting hole.

[0007] Furthermore, when the drive column on the left moves to the left, the drive rod presses against the spiral groove, the rotating rod rotates clockwise, and the inner and outer rings of the one-way bearing are locked.

[0008] Furthermore, each of the housings has a sliding hole on its upper side plate. The hinge includes a sleeve and a connecting rod. The sleeve is fixed to the center of the bottom surface of the top plate. A connecting plate is fixed to the top surface of each drive column. The upper end of each connecting plate passes through the sliding hole on the housing. A connecting rod is hinged to the upper end of each connecting plate. The other end of the connecting rod is higher than the connecting plate and is hinged to the outer wall of the sleeve.

[0009] Furthermore, a column is fixed at the center of the top surface of the base plate, the upper end of the column extends into the sleeve, the inner wall of the sleeve slides in contact with the peripheral wall of the column, and the upper end of the column is connected to the inner top surface of the sleeve via a buffer spring.

[0010] The beneficial effects of this utility model through the above technical solution are as follows: When this utility model is in use, the vertical vibration generated by the crusher can be partially converted into the potential energy of the shock-absorbing spring, buffer spring one and buffer spring two, and the other part drives the rotating rod to rotate the friction plate one. The friction plate one and the friction plate two come into contact with each other, and the vibration energy is converted into the internal energy between the friction plate one and the friction plate two. The one-way bearing of this invention ensures that frictional energy dissipation only occurs in the main direction of vibration input, and avoids ineffective friction during upward rebound, thereby reducing energy waste and preventing jamming caused by bidirectional friction.

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-5 As shown, a shock-absorbing device for barite powder processing includes a crusher 1 mounted on a shock-absorbing base. The shock-absorbing base includes a top plate 2 and a bottom plate 3 elastically connected. Both the bottom plate 3 and the top plate 2 are rectangular plates. Vertical cylinders 4 are fixed to the four corners of the top surface of the bottom plate 3, and movable columns 5, corresponding one-to-one with the vertical cylinders 4, are fixed to the four corners of the bottom surface of the top plate 2. The lower end of each movable column 5 extends into the corresponding vertical cylinder 4, and the lower end of each movable column 5 is connected to the top surface of the bottom plate 3 via a shock-absorbing spring 6. The crusher 1 is fixed to the top surface of the top plate 2. The device also includes energy-consuming components arranged in a ring between the top plate 2 and the bottom plate 3. Each energy-consuming component includes a housing 7 and a rotating rod 8. The housing 7 is fixed to the top surface of the bottom plate 3 and is a rectangular shell with its upper opening sealed by an upper side plate. A partition 9, far from the center of the bottom plate 3, is fixed inside the housing 7. Plate 9 is a rectangular plate with the inner side of the shell 7 fixed to its side. The rotating rod 8 is a round rod. The outer end of the rotating rod 8 movably passes through the partition 9 and is rotatably connected to friction plate 10. The inner end of the rotating rod 8 is rotatably connected to the inner end of the shell 7. The outer end of the rotating rod 8 is away from the center of the bottom plate 3, and the other end is the inner end. Friction plate 10 is in frictional contact with friction plate 11 fixed on the inner surface of the outer end of the shell 7. The rotating rod 8 has a spiral groove 12. A drive column 13 is slidably sleeved on the outside of the rotating rod 8. A drive rod 14 with its end extending into the spiral groove 12 is fixed on the drive column 13. The drive column 13 is connected to the top plate 2 via a hinge. When the top plate 2 moves downward or upward, the drive column 13 is driven away from or closer to the center of the bottom plate 3 via the hinge. When the drive column 13 moves away from the center of the bottom plate 3 and drives the rotating rod 8 to rotate, friction plate 10 rotates with the rotating rod 8.

[0014] The friction plate 10 is a circular plate made of metal-based fiber reinforced material, and the friction plate 11 is a rectangular plate made of metal-based fiber reinforced material.

[0015] The outer end of the rotating rod 8 is rotatably connected to the friction plate 10 via a one-way bearing 15, and the inner end is rotatably connected to the inner end of the housing 7 via a two-way bearing 16. The driving column 13 is a rectangular column that slides in contact with the inner side of the housing 7. The driving column 13 is slidably sleeved on the corresponding rotating rod 8 through a through hole 17 in the middle. The driving rod 14 extends from the top surface of the driving column 13 into the through hole 17. The driving rod 14 is fixedly connected to the driving column 13. The driving rod 14 is a cylinder whose end slides in contact with the spiral groove 12. The outer end of the driving column 13 is connected to the partition 9 inside the housing 7 via a buffer spring 18.

[0016] The friction plate 10 has a recessed mounting hole 19 on the side facing the corresponding rotating rod 8. The inner ring of the one-way bearing 15 is fixedly connected to the outer wall of the rotating rod 8, and the outer ring is fixedly connected to the circumferential surface of the mounting hole 19. The spiral groove 12 of the left rotating rod 8 rotates to the left. When the drive column 13 on the left moves to the left, the drive rod 14 presses against the spiral groove 12, causing the rotating rod 8 to rotate clockwise. The inner ring of the left one-way bearing 15 rotates clockwise along with the rotating rod 8 (the clockwise rotation of the left rotating rod 8 is...). Figure 3 (From the right-side view), the inner and outer rings of the one-way bearing 15 are locked; when the left drive column 13 moves to the right, the rotating rod 8 rotates counterclockwise, and the inner ring of the left one-way bearing 15 rotates counterclockwise with the rotating rod 8, while the inner and outer rings of the one-way bearing 15 are in a free state.

[0017] Each of the upper side plates of the housing 7 is provided with a sliding hole 20. The sliding hole 20 is a rectangular hole opened along the length direction of the housing 7. The hinge includes a sleeve 21 and a connecting rod 22. The sleeve 21 is fixed to the center of the bottom surface of the top plate 2. A connecting plate 29 is fixed to the top surface of each drive column 13. The upper end of each connecting plate 29 passes through the sliding hole 20 on the housing 7. A connecting rod 22 is hinged to the upper end of each connecting plate 29. The other end of the connecting rod 22 is higher than the connecting plate 29 and is hinged to the outer wall of the sleeve 21.

[0018] Each of the connecting rods 22 has a U-shaped groove 23 at both ends. One U-shaped groove 23 is fitted onto the outside of the corresponding connecting plate 29. The U-shaped groove 23 is rotatably connected to the connecting plate 29 via a rotating rod 24. A connecting plate 25 corresponding to the other U-shaped groove 23 is fixed on the outer wall of the sleeve 21. The connecting plate 25 extends into the corresponding U-shaped groove 23. The U-shaped groove 23 is rotatably connected to the connecting plate 25 via a rotating rod 26.

[0019] A column 27 is fixed at the center of the top surface of the base plate 3. The column 27 is a cylinder. The upper end of the column 27 extends into the sleeve 21. The inner wall of the sleeve 21 slides in contact with the peripheral wall of the column 27. The upper end of the column 27 is connected to the inner top surface of the sleeve 21 via a buffer spring 28.

[0020] When in use, the vibration generated by the crusher 1 is transmitted to each movable column 5 through the top plate 2. Each movable column 5 moves downward and converts the vibration energy into the potential energy of the damping spring 6, which can convert a part of the vibration energy. When the top plate 2 moves downward, the sleeve 21 moves downward with the top plate 2. The sleeve 21 moves downward and compresses the second buffer spring 28. The vibration energy is converted into the potential energy of the second buffer spring 28, which converts a part of the vibration energy. As the sleeve 21 moves downward with the top plate 2, the downward movement of the sleeve 21 drives one end of each connecting rod 22 connected to the corresponding connecting plate 29 to move away from the center of the bottom plate 3. Each connecting plate 29 drives the connected drive column 13 to move away from the center of the bottom plate 3. The buffer spring 18 is compressed, and part of the vibration energy is converted into the potential energy of the buffer spring 18. The drive rod 14 on the drive column 13 presses against the spiral groove 12, and the drive rotating rod 8 drives the friction plate 10 to rotate. The friction plate 10 comes into contact with the friction plate 21 on the same side, converting part of the vibration energy into the internal energy generated by friction between the friction plate 10 and the friction plate 21. The top plate 2 moves towards... During downward movement, the friction energy dissipation of this invention only occurs. When the top plate 2 rebounds upward, the one-way bearing 15 is in a free state, and the rotating rod 8 can rotate freely. The friction energy dissipation does not work, avoiding unnecessary motion interference and energy backflow, making the system work more smoothly and reliably, and avoiding the jamming problem caused by bidirectional friction. Therefore, when this invention is in use, part of the vibration generated by the crusher 1 can be converted into the potential energy of the shock-absorbing spring 6, buffer spring 18 and buffer spring 28, and another part can be converted into the internal energy between the friction plate 10 and the friction plate 21, reducing the vibration amplitude of the crusher 1 and preventing premature damage to the internal components of the crusher 1 due to severe vibration.
