Description

Technical Field

[0001] This utility model relates to the technical field of detecting the dynamic effects of fluid flow, specifically a protective device for preventing damage to a vortex steam flow meter used in pigment production. Background Technology

[0002] Vortex steam flow meters are core equipment for measuring steam flow in the pigment production field. Steam is widely used in pigment production for key processes such as reactor heating, raw material drying, and process temperature control. The accuracy of its flow measurement and operational stability directly affect the color uniformity, purity consistency, and production energy consumption statistics of pigment products. It is crucial for ensuring that pigment production processes meet standards and product quality is stable. In practical applications of pigment production, vortex steam flow meters need to be connected to the steam delivery system through pipelines. However, when transporting high-temperature and high-pressure steam, the steam pipelines used for pigment production will experience continuous vibration due to factors such as frequent pump and valve start-stop impacts caused by the intermittent process of pigment production, medium flow pulsation, and the thermal expansion and contraction of the pipeline itself.

[0003] In traditional installation methods, vortex steam flow meters are often directly connected to the steam pipelines used in pigment production using rigid flanges. This rigid connection structure cannot effectively buffer pipeline vibrations, causing these vibrations to be directly transmitted to the flow meter body. This leads to the loosening and failure of internal components, specifically loosening of the bolts connecting the vortex generator and the detection probe, and poor contact of the signal transmission module. This not only causes a significant decrease in flow measurement accuracy, leading to deviations from preset standards in pigment production process parameters and affecting batch consistency, but also long-term high-frequency vibration can cause aging and damage to the flow meter's seals, resulting in steam leakage. Steam leakage not only wastes energy but may also affect the stability of pigment particles due to abnormal humidity, and even cause irreversible damage such as cracking of the flow meter casing, impacting pigment production safety and equipment lifespan.

A turntable 23 is installed on the front side of the second adjusting block 17. The function of the second adjusting block 17 is to provide installation space for components such as the first adjusting block 16 and the support shaft 20, and at the same time transmit the support force.

[0037] Lifting groove 18: Lifting groove 18 is opened on the upper side of the second adjusting block 17. The lower side of the first adjusting block 16 is slidably connected inside the lifting groove 18. The function of lifting groove 18 is to restrict the movement direction of the first adjusting block 16, ensuring that the first adjusting block 16 can only move up and down in the vertical direction to avoid deviation.

[0038] Transmission groove 19: Transmission groove 19 is formed inside the second adjusting block 17. Transmission groove 19 is located below the lifting groove 18. The transmission groove 19 is used to install components such as support shaft 20, worm gear 22, transmission rod 24, and worm 25.

[0040] Second threaded rod 21: The second threaded rod 21 is fixedly connected to the upper end of the support shaft 20. The upper end of the second threaded rod 21 extends into the interior of the first adjusting block 16. The second threaded rod 21 forms a threaded engagement with the first adjusting block 16 by rotation. The function of the second threaded rod 21 is to drive the first adjusting block 16 to move up and down along the lifting groove 18.

[0041] Worm Gear 22: Worm gear 22 is fixedly sleeved on the outer surface of support shaft 20. Worm gear 22 is meshed with worm 25. Worm gear 22 transmits rotational motion to support shaft 20 through meshing with worm 25. The function of worm gear 22 is to realize power transmission and drive support shaft 20 to rotate.

[0042] Turntable 23: Turntable 23 is installed on the front side of the second adjusting block 17, and the transmission rod 24 is fixedly connected to the rear side of turntable 23. The function of turntable 23 is to provide a gripping part for the operator. By rotating turntable 23, the transmission rod 24 is driven to rotate.

[0043] Transmission rod 24: Transmission rod 24 is fixedly connected to the rear side of turntable 23. The rear end of transmission rod 24 extends into the interior of transmission groove 19 and is rotatably connected to the rear wall of transmission groove 19. Worm gear 25 is fixedly sleeved on the outer surface of transmission rod 24. The function of transmission rod 24 is to transmit the rotational motion of turntable 23 and drive worm gear 25 to rotate synchronously.

[0044] Worm 25: Worm 25 is fixedly sleeved on the outer surface of transmission rod 24. Worm 25 is meshed with worm wheel 22. Worm 25 drives worm wheel 22 to rotate by rotating. The function of worm 25 is to transmit the rotational motion of transmission rod 24 to worm wheel 22 to realize speed reduction transmission and improve adjustment accuracy.

[0045] Furthermore, the vibration of the steam pipeline 2 caused by the flow of the medium or external interference is greatly weakened by the corrugated pipe 3 connected to the front and rear sides of the vortex steam flow meter 1. The corrugated pipe 3 absorbs the vibration energy of the steam pipeline 2 through its own flexible deformation axial expansion and contraction and radial micro-oscillation, reducing the direct transmission of vibration to the vortex steam flow meter 1.

[0046] The two upper clamping rings 6 and the two lower clamping rings 6 on the outer surface of the vortex steam flow meter 1 cooperate to form two front and rear rings. The rubber pad on the inner surface directly adheres to the outer shell of the vortex steam flow meter 1, which avoids rigid contact that could scratch the outer shell, and also buffers the small residual vibrations of the vortex steam flow meter 1 itself through the elasticity of the rubber pad.

[0047] The clamping mechanism achieves stable clamping of the vortex steam flow meter 1 through mechanical locking. The two fixing blocks 7 on the right side are rotatably connected by a rotating shaft 8, allowing the upper and lower clamping rings 6 to open and close around the rotating shaft 8 for easy installation / removal. The first connecting block 9 on the left side is connected to the upper clamping ring 6, and the second connecting block 10 is connected to the lower clamping ring 6. They are locked by a connecting ball 11, a first threaded rod 13, and a clamping nut 14. The connecting ball 11 rotates flexibly in the groove of the first connecting block 9 through two rotating rods 12, ensuring that the first threaded rod 13 can adapt to the closing angle of the upper and lower clamping rings 6. When the clamping nut 14 is turned up, it comes into contact with the lower surface of the second connecting block 10 and applies pressure, clamping the first connecting block 9 and the second connecting block 10. Finally, the upper and lower clamping rings 6 form a ring-shaped limit on the vortex steam flow meter 1. The limit block 15 prevents the clamping nut 14 from falling off the first threaded rod 13.

[0048] The fixed base 4 is rigidly connected to the ground or wall by the fixing bolts 5, providing a stable foundation for the entire device. The two support mechanisms are symmetrically connected to the lower clamping ring 6 and the fixed base 4, realizing the height adjustment and radial stability of the vortex steam flow meter 1. The rotating turntable 23 drives the transmission rod 24 to rotate, causing the worm gear 25 fixed on the transmission rod 24 to rotate synchronously. The worm gear 25 meshes with the worm wheel 22 to drive the support shaft 20 and the second threaded rod 21 fixed on its upper end to rotate. The second threaded rod 21 is threadedly engaged with the first adjusting block 16 on the lower clamping ring 6. Under the guidance and restriction of the lifting groove 18, the first adjusting block 16 is driven to slide up and down along the lifting groove 18, thereby adjusting the height of the clamping ring 6 and the vortex steam flow meter 1 to adapt to different installation scenarios. At the same time, the rigid connection between the second adjusting block 17 and the fixed base 4 limits the excessive radial offset of the vortex steam flow meter 1, avoiding damage to the bellows 3 due to excessive deformation.

[0049] Example: Horizontal fine-tuning scenario Please see Figure 5 A bubble level 26 is embedded and installed on the upper side of the fixed base 4, between the two second adjusting blocks 17. The surface of the bubble level 26 is flush with the upper side of the fixed base 4, so as not to affect the installation and operation of components such as the clamping ring 6 and the first adjusting block 16.

[0050] After adding the bubble level 26, when installing the mounting base 4, the position of the bubble in the bubble level 26 is observed to determine whether the mounting base 4 is level. If the bubble is offset, it means that the vortex steam flow meter 1 is tilted with the mounting base 4. At this time, adjust the tightness of the fixing bolt 5 and fine-tune the contact angle between the mounting base 4 and the ground until the bubble in the bubble level 26 is centered. Then tighten the fixing bolt 5 to ensure that the vortex steam flow meter 1 is in a level state.

[0051] After adding the bubble level 26, the bubble level 26 can intuitively display the horizontal status of the fixed base 4. No external level measuring tool is needed during installation, simplifying the operation. By observing the bubble position of the bubble level 26 in real time, the installation angle of the fixed base 4 can be quickly adjusted to ensure the levelness of the vortex steam flow meter 1 and reduce measurement errors caused by tilting. The structure is simple, only adding the bubble level 26, without changing the original connection relationship between the fixed base 4, the vortex steam flow meter 1, and the support mechanism, making it suitable for various scenarios with requirements for installation accuracy.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
