Description

Technical Field

[0001] The utility model relates to the field of pipeline shock absorption, in particular to an axial elastic compensation component of a pipeline shock absorber. Background Art

[0002] In the chemical industry, particularly in the lithium carbonate production sector, processes such as ore extraction involve extensive vibration and screening equipment, as well as the conveying of powdered materials. During these processes, the vibrations generated by the equipment are complex, including directional tilting and swinging, as well as axial displacement, with greater amounts of swing and axial displacement occurring during the startup phase. Furthermore, the materials being conveyed are often dry powders, small particles, or a mixture of both, often at temperatures exceeding 600°C.

[0003] Existing conventional pipe shock absorbers are typically made of elastic or flexible materials such as metal mesh and bellows. However, under such conditions of complex vibration and high-temperature materials, conventional shock absorbers are prone to numerous problems. Due to the multi-directional, large displacement, long-term, and high-frequency characteristics of vibration, the elastic or flexible materials are prone to rapid metal fatigue cracking and breaking due to alternating stress. Moreover, the high temperature transmitted by the material can significantly reduce the fatigue strength of these materials, and may even cause them to melt or be damaged directly due to their inability to withstand the high temperature. How to invent an axial elastic compensation component for pipe shock absorbers to improve these problems has become a problem that technicians in this field urgently need to solve.

DETAILED DESCRIPTION

[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 to 3 The utility model provides a technical solution: an axial elastic compensation component of a pipeline shock absorber, a pipeline mechanism 100 for elastic compensation, the pipeline mechanism 100 includes a feed connecting pipe 110 and a discharge connecting pipe 120, and also includes

[0026] The elastic compensation mechanism 200 includes a shock absorber 210, which is equally divided and installed around the outside of the feed connecting pipe 110. The top and bottom of the shock absorber 210 are respectively limitedly connected with connecting parts 220. The connecting parts 220 are limitedly connected to the top and bottom flange surfaces of the feed connecting pipe 110. A mounting seat 230 is connected between the connecting parts 220 and the flange surfaces of the feed connecting pipe 110 by a ball joint.

[0027] The shock absorber 210 absorbs and buffers the axial vibration energy of the pipeline through its own elastic deformation, converting it into other forms of energy (such as elastic potential energy, etc.), thereby effectively reducing the axial displacement amplitude of the pipeline.

[0028] The connector 220 and the mounting seat 230 allow the shock absorber 210 to adaptively adjust following the movement of the feed connecting pipe 110. The shock absorber 210 also limits the left-right and front-back horizontal displacement and bending of the feed connecting pipe 110, so that the feed connecting pipe 110 can only be compressed axially.

[0029] See also Figures 3 to 5 An upper connecting seat 211 is provided at the top of the shock absorber 210 , and a lower connecting seat 212 is provided at the bottom of the shock absorber 210 .

[0030] The connector 220 includes a connecting buckle 221, which is U-shaped. The inner walls of the connecting buckle 221 respectively abut against the two sides of the upper connecting seat 211 and the lower connecting seat 212. A limiting bolt 222 is provided through the bottom of the upper connecting seat 211. The limiting bolt 222 penetrates the upper connecting seat 211 and the lower connecting seat 212 to lock the upper connecting seat 211 and the lower connecting seat 212. The limiting bolt 222 further enhances the firmness of the connection between the upper connecting seat 211 and the lower connecting seat 212. By tightening the limiting bolt 222, the upper connecting seat 211 and the lower connecting seat 212 can be tightly fitted together, preventing the connection from loosening due to vibration or other reasons during pipeline operation, thereby ensuring a stable and reliable connection between the shock absorber 210 and the connector 220.

[0031] The U-shaped bottom of the connecting clip 221 has a through hole, through which a connecting bolt 223 is installed. An upper limit nut 224, a lower limit nut 225, and a lower locking nut 226 are respectively threaded onto the connecting bolt 223. The upper limit nut 224 is located inside the connecting clip 221, while the lower limit nut 225 and the lower locking nut 226 are located outside the connecting clip 221.

[0032] The mounting seat 230 includes a cylindrical seat 231 , the internal ball joint of the cylindrical seat 231 is connected to a ball head 232 , the ball head 232 is connected to one end of the outer side of the connecting bolt 223 , and the cylindrical seat 231 is fixedly mounted on the flange surface of the feed connecting pipe 110 .

[0033] One side of the connecting bolt 223 is fixedly connected to a connecting cylinder 233 . The connecting bolt 223 is located outside the cylinder seat 231 . The connecting cylinder 233 is threadedly connected to the connecting bolt 223 .

[0034] The lower limiting nut 225 abuts against the outer wall of the connecting buckle 221 , and the lower locking nut 226 abuts against the end of the connecting bolt 223 . A gasket is provided between the lower locking nut 226 and the connecting bolt 223 .

[0035] The upper limit nut 224 is located inside the connecting buckle 221, which can prevent the connecting bolt 223 from axially displacing inside the connecting buckle 221; the lower limit nut 225 and the lower locking nut 226 are respectively located outside the connecting buckle 221, and the lower limit nut 225 can abut against the outer wall of the connecting buckle 221 to play a preliminary limiting role, and the lower locking nut 226 is used for final tightening to ensure the reliability of the connection, and a gasket is set between them to increase friction and prevent the nut from loosening.

[0036] The inner bottom of the cylinder seat 231 is provided with a step, and above the step is a bottom inner seat 234. One end of the bottom inner seat 234 slides in contact with the ball head 232. The inner top of the cylinder seat 231 is provided with a top inner seat 235. A through hole is formed in the middle of the top inner seat 235. The top inner seat 235 is sleeved on the outside of the connecting cylinder 233, and one end of the top inner seat 235 slides in contact with one side of the ball head 232. The hole is used to accommodate the connecting cylinder 233, ensuring its normal installation and movement. At the same time, the sliding contact between the top inner seat 235 and the ball head 232 ensures that the force applied to the ball head 232 is uniform during rotation, improving the performance and reliability of the ball joint connection. The position of the connecting bolt 223 is locked by screwing the connecting bolt 223 to a suitable position in the connecting buckle 221 and then rotating the upper limit nut 224 and the lower limit nut 225 to prevent the connecting bolt 223 from being displaced. The lower locking nut 226 is used to abut and lock with the connecting tube 233.

[0037] A threaded retaining ring 236 is threadedly mounted on the top of the cylinder seat 231. The center of the retaining ring 236 is hollow, and the connecting cylinder 233 is located in the hollow space of the retaining ring 236. This ensures the stability of the ball joint connection structure. The threaded mounting method allows for easy adjustment of the position of the retaining ring 236, thereby precisely limiting the position of the connecting cylinder 233 and the top inner seat 235, ensuring the proper function of the entire elastic compensation component.

[0038] Working Principle: When the feed manifold 110 is subjected to axial vibration displacement, the elastic shock absorber 210 absorbs and buffers the energy generated by the axial vibration through its own compression or tension deformation, thereby compensating for the axial displacement of the feed manifold 110. When the feed manifold 110 displaces upward axially, the shock absorber 210 is compressed, converting the axial displacement energy into stored elastic potential energy. When the axial displacement force disappears, the shock absorber 210 returns to its original state under the action of the elastic restoring force, pushing the feed manifold 110 back to its original position.

[0039] While the feed connecting pipe 110 is undergoing axial displacement, due to the complexity of the equipment vibration, the feed connecting pipe 110 may also produce slight displacements and angle changes in other directions. At this time, the ball hinge connection of the mounting seat 230 comes into play. The ball head 232 can rotate freely in the cylinder seat 231, so that the connection between the connector 220 and the flange surface of the feed connecting pipe 110 can adapt to this multi-directional movement. The bottom inner seat 234 and the top inner seat 235 play a supporting and guiding role during the rotation of the ball head 232, ensuring that the ball head 232 rotates smoothly, thereby ensuring that the entire elastic compensation component can work effectively under different working conditions, maintaining a stable connection between the feed connecting pipe 110 and the discharge connecting pipe 120, and protecting the pipeline system from damage due to excessive vibration.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
