Description

Technical Field

[0001] The utility model relates to the technical field of dust removal pipelines, in particular to a wear-resistant device for dust removal pipelines. Background Art

[0002] During the long-term operation of the dust removal pipeline, affected by the friction between the dust removal ash and the air, the pipe wall has been severely worn. Several repairs have been carried out on the outer side of the pipe wall, steel plates have been welded and concrete has been poured, but the problem of pipeline wear cannot be fundamentally solved. Some pipe walls are as thin as cicada wings, but no problems can be found from the outside. Only when the pipe wall is worn through and leaks air will the problem be discovered. By then, if repaired by welding from the outside, it will not only affect production but also pose a safety hazard. Therefore, a wear-resistant device for dust removal pipelines is proposed here.

[0022] Please refer to Figures 1 to 4As shown in the figure, the utility model provides a technical solution: a wear-resistant device for a dust removal pipeline, which includes a dust removal pipeline body 1. A wear-resistant device 2 is coated on the outside of the dust removal pipeline body 1. The wear-resistant device 2 includes a wear-resistant plate 3 attached to the outer wall of the dust pipeline body 1. The wear-resistant plate material is a ceramic wear-resistant plate. An arc-shaped plate 4 is arranged outside the wear-resistant plate 3. The arc-shaped plate 4 is fixedly connected to the dust removal pipeline body 1. The wear-resistant plate 3 is fixed on the outer wall of the dust removal pipeline body 1 through the arc-shaped plate 4. First, an arc-shaped plate that conforms to the shape of the dust removal pipeline body 1 is made according to the shape of the dust removal pipeline body 1, and then pieces of wear-resistant plate materials 301 are fixed inside the arc-shaped plate. Without affecting normal production, the arc-shaped plate with the wear-resistant plate materials 301 fixed is welded on the outside of the dust removal pipeline body 1. By adding a wear-resistant plate 3 that is adapted and fitted to the outside of the dust removal pipeline body 1 and using the arc-shaped plate 4 to fix the wear-resistant plate 3, a wear-resistant structure can be added to the outer wall of the dust removal pipeline body 1, ensuring the service life of the pipeline.

[0023] Please refer specifically to Figure 2 and Figure 3 , the wear-resistant plate 3 is composed of a plurality of wear-resistant plate materials 301 of the same specification. The cross-section of the wear-resistant plate 3 is arc-shaped. One side of it is attached to the dust removal pipeline body 1, and the other side is attached to the arc-shaped plate 4. The arc-shaped plate 4 is composed of multiple end semi-circular arc plates 401 welded together.

[0024] Please refer specifically to Figure 4 , a stud 5 is welded on the arc-shaped plate 4. A nut 6 is threadedly connected to the stud 5. A fixing hole 7 is opened at the center of the wear-resistant plate 3. The fixing hole 7 is a stepped hole. The stud 5 is inserted into the fixing hole 7. The wear-resistant plate 3 is fixed on the arc-shaped plate 4 through the stud 5 and the nut 6.

[0025] Working principle: First, an arc-shaped plate that conforms to the shape of the dust removal pipeline body 1 is made according to the shape of the dust removal pipeline body 1, and then pieces of wear-resistant plate materials 301 are fixed inside the arc-shaped plate. Without affecting normal production, the arc-shaped plate with the wear-resistant plate materials 301 fixed is welded on the outside of the dust removal pipeline body 1. Multiple arc-shaped plates are butted to form a closed loop, which is equivalent to adding a wear-resistant structure outside the dust removal pipeline body 1, ensuring the service life of the pipeline. Through experiments, the pipeline can be used normally for 6 - 10 years without being affected.
