Description

TECHNICAL FIELD

[0001] The utility model relates to material conveying technical field, concretely is a rutile dry material conveying pipeline. BACKGROUND

[0002] Rutile is an industrial mineral raw material with great value, and is widely used in many industries such as pigments, electronics, metallurgy, but due to the significant characteristics of rutile dry material itself, its hardness is high, the crystal structure makes the particle edge sharp, and when conveying by airflow or mechanical force, the dry material particles frequently rub, and the flowability is poor.

[0003] The traditional metal or ordinary plastic material conveying pipeline is subjected to long-term 'erosion' of rutile dry material, and the wear rate is extremely fast, which not only makes the enterprise frequently invest high cost for pipeline replacement, but also greatly affects the overall production benefit and capacity due to the production interruption caused by maintenance downtime. Therefore, a new type of conveying pipeline capable of adapting to rutile dry material conveying and significantly reducing pipeline wear is urgently needed. SUMMARY

[0004] The utility model discloses a rutile dry material conveying pipeline to solve the problems in the background art.

[0005] To solve the above technical problems, the utility model provides the following technical scheme: a rutile dry material conveying pipeline, including pipeline main part, the pipeline main part is integrally formed structure, the inner wall of pipeline main part is equipped with wear -resisting inner lining layer, buffer layer and support layer from inside to outside in proper order.

[0006] As a further description of the above scheme, the wear -resisting inner lining layer adopts the material of ultrahigh molecular weight polyethylene, and the inner surface of the wear -resisting inner lining layer is provided with a plurality of grooves uniformly distributed along the axial direction.

[0007] As a further description of the above scheme, the buffer layer is of rubber material, the buffer layer is tightly attached to the outside of the wear -resisting inner lining layer, and a plurality of hollow elastic air bags are uniformly distributed in the buffer layer.

[0008] As a further description of the above scheme, the support layer is of metal material, the support layer is tightly attached to the outside of the buffer layer, and a corrosion -resistant coating is arranged on the outside of the support layer.

[0009] Compared with the prior art, the utility model has the beneficial effects that:

[0010] 1. The wear-resistant inner lining layer is made of ultra-high molecular weight polyethylene material, which has extremely low friction coefficient and can effectively reduce the friction between the rutile dry material and the inner wall of the pipeline. At the same time, the excellent wear resistance of the wear-resistant inner lining layer can withstand the material erosion and friction for a long time. In addition, the grooves uniformly distributed along the axial direction not only guide the orderly flow of the material and avoid accumulation, but also disperse the impact force of the material particles, further reducing the wear of the inner lining layer, thereby greatly reducing the wear degree of the entire pipeline, prolonging the service life of the pipeline, and reducing the cost investment and production interruption problems caused by frequent replacement of the pipeline.

[0011] 2. The rubber material in the buffer layer and the uniformly distributed elastic air bags work together to buffer the impact of the rutile dry material particles on the inner wall of the pipeline in all directions, avoid damage to the inner lining layer and the overall structure of the pipeline caused by impact, indirectly reduce the local wear caused by impact, and ensure the long-term stable operation of the pipeline, which helps to maintain stable production order.

[0017] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0018] Please refer to Figures 1-4 The present application provides a technical solution: a rutile dry material conveying pipeline, which comprises a pipeline main body 1, the pipeline main body 1 is an integral structure, and the inner wall of the pipeline main body 1 is provided with a wear-resistant inner lining layer 2, a buffer layer 3 and a support layer 4 from inside to outside.

[0019] Specifically, as Figure 3As shown: the wear-resistant inner lining layer 2 is made of ultra-high molecular weight polyethylene material, and the inner surface of the wear-resistant inner lining layer 2 is provided with a plurality of grooves 2.1 distributed in the axial direction. The ultra-high molecular weight polyethylene material has a very low friction coefficient, which can effectively reduce the friction between the rutile dry material and the inner wall of the pipeline, and at the same time has excellent wear resistance, which can withstand the long-time erosion and friction of the rutile dry material; the design of the groove 2.1 can guide the material flow, reduce the accumulation of the material on the inner wall of the pipeline, reduce the risk of local wear, and make the material conveying more stable and efficient.

[0020] Specifically, as shown in the figure, Figure 4 As shown: the buffer layer 3 is made of rubber material, which is closely attached to the outside of the wear-resistant inner lining layer 2, and a plurality of hollow elastic air bags 3.1 are uniformly distributed in the buffer layer 3. The elastic property of rubber can buffer the impact force generated by the impact of rutile dry material particles on the inner wall of the pipeline, reduce the damage to the wear-resistant inner lining layer 2 and the whole pipeline caused by impact, and further protect the integrity of the pipeline structure; the design of the elastic air bag 3.1 can provide additional buffering effect when impacted, enhance the buffering effect, and better protect the pipeline together with the rubber material.

[0021] Specifically, as shown in the figure, Figure 2 As shown: the support layer 4 is made of metal material, usually carbon steel or stainless steel, and the outer side of the support layer 4 is provided with a corrosion-resistant coating. Because the rutile dry material conveying environment is complex, there may be corrosive medium, and the corrosion-resistant coating can prevent the metal support layer 4 from rusting and corroding, prolonging the service life of the whole pipeline.

[0022] In use, when the rutile dry material is conveyed in the pipeline, the material first contacts the wear-resistant inner lining layer 2, and by virtue of its low friction coefficient characteristic, the material can flow more smoothly, reducing the wear of the wear-resistant inner lining layer 2. If the material particles impact the inner wall of the pipeline, the rubber and elastic air bags 3.1 of the buffer layer can effectively absorb the impact energy, avoiding damage to the wear-resistant inner lining layer 2 and the support layer 4 due to impact. The support layer 4 provides mechanical support while the corrosion-resistant coating on the outer side of the support layer 4 resists external corrosive factors, ensuring long-term stable operation of the pipeline.

[0023] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
