Description

Technical Field

[0001] The utility model relates to the technical field of bellows, in particular to a wear-resistant bellows compensator. Background Art

[0002] A bellows is a tubular elastic sensitive element formed by connecting foldable corrugated sheets along the folding and expansion direction. Its main use is as a measuring element of a pressure measuring instrument to convert pressure into displacement or force.

[0003] The application scope of bellows includes instrumentation systems, medical equipment, automotive industry, packaging materials and construction fields. In addition, bellows can also be used as compensation elements to compensate for temperature errors caused by elements, or used for connections between two elements. The bellows compensator uses the effective expansion and contraction of its working body, the bellows, to absorb the dimensional changes of pipelines, ducts, containers, etc. caused by thermal expansion and contraction, or compensate for the axial, lateral and angular displacements of pipelines, ducts, containers, etc. It can also be used to reduce noise and vibration, and is widely used in modern industry.

[0004] In the prior art, high-temperature slag ash discharged from large steel mills and thermal power plants is usually discharged through closed pipelines. The flowing high-temperature slag will cause thermal deformation of the pipeline. The main form of pipeline deformation is axial displacement. In order to avoid the influence of axial displacement on pipeline stability, a corrugated compensator is installed in the pipeline. The corrugated compensator absorbs axial displacement through the corrugated structure. However, when the high-temperature slag ash flows in the corrugated compensator, the inner wall of the bellows is thinner than the pipeline and is severely worn by the slag ash, which affects the service life of the corrugated compensator.

[0038] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] like Figure 1 to Figure 4As shown, this embodiment proposes a wear-resistant bellows compensator, including a bellows compensator body 1, and also includes a sleeve 2, a buffer mechanism, a buffer plate 3, a flow-reducing mechanism, an input pipe 4 and a buffer leaf 5. The sleeve 2 is fixedly connected in the bellows compensator body 1, the buffer mechanism is installed in the sleeve 2, a plurality of buffer plates 3 are provided, and the plurality of buffer plates 3 are located in the sleeve 2, the flow-reducing mechanism is installed in the bellows compensator body 1, the input pipe 4 is fixedly connected to one end of the bellows compensator body 1, a plurality of buffer leaves 5 are provided, and the plurality of buffer leaves 5 are located in the input pipe 4, the buffer mechanism takes effect when the slag enters the sleeve 2, and when the slag rushes into the sleeve 2, it will generate friction and collision with the inner wall of the sleeve 2, while in this scheme, the slag first impacts the buffer plate 3, and the damage to the sleeve 2 is greatly reduced, and the flow-reducing mechanism is used to slow down the slag when it is about to enter the bellows compensator, so as to reduce the damage to the buffer plate 3 caused by its excessive impact force.

[0040] Among them, the buffer mechanism includes a mounting groove 6, a spring 7 and a feed slope 8. The mounting groove 6 is opened on the inner wall of the sleeve 2. Multiple buffer plates 3 are located in the mounting groove 6. There are multiple springs 7. Each buffer plate 3 is fixedly connected to a side close to the mounting groove 6 with multiple springs 7. There are multiple feed slopes 8. One end of each buffer plate 3 close to the input pipe 4 is opened with a feed slope 8. When the slag impacts the buffer plate 3, the spring 7 can reduce the damage caused by the impact force, and the feed slope 8 can prevent the slag from accumulating at the connection.

[0041] Secondly, the slow-flow mechanism includes a rotating groove 9, a rotating ring 10, a limit block 11 and a fixed component. The rotating groove 9 is opened on the inner wall of the input pipe 4, the rotating ring 10 is slidably connected in the rotating groove 9, a plurality of buffer leaves 5 are arranged in a ring on the inner wall of the rotating ring 10, the limit block 11 is fixedly connected to the side wall of the rotating ring 10, and the fixed component is installed between the input pipe 4 and the sleeve 2. The slow-flow mechanism is used to slow down the slag that is about to enter the corrugated compensator but has not yet entered the corrugated compensator, so as to prevent the slag from passing through quickly and causing greater wear or impact on the buffer plate 3.

[0042] Again, the fixing assembly includes a fixing plate 12 and a bolt 13. There are multiple fixing plates 12, and the multiple fixing plates 12 are respectively fixed between the input pipe 4 and the sleeve 2. There are multiple bolts 13, and every two matching fixing plates 12 are detachably connected by bolts 13. The fixing assembly is used to fix the input pipe 4.

[0043] Among them, multiple buffer leaves 5 are arranged on the inner wall of the input pipe 4 in the same direction and tilted in the horizontal direction. At this time, when the slag impacts the buffer leaves 5, the tilted buffer leaves 5 can drive the rotating ring 10 to rotate slightly under the action of the component force, thereby unloading part of the force from the slag, so as not to be quickly damaged under the larger impact force.

[0044] Finally, the plurality of buffer plates 3 are closely arranged in the mounting groove 6 , and the plurality of buffer plates 3 completely fill the mounting groove 6 .

[0045] In this embodiment, the slag first enters the input pipe 4 from the pipeline, and when passing through the buffer leaf 5, the buffer leaf 5 reduces the flow rate of the slag, and then enters the casing 2. When entering the casing 2, the slag impacts the buffer plate 3. The spring 7 under the buffer plate 3 can absorb a certain impact force, protect the casing 2 and the buffer plate 3 from less friction and impact force, and extend the service life of the bellows compensator.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
