Description

Technical Field

[0001] The utility model relates to the technical field of composite pipes, in particular to a wear-resistant composite pipe with a long service life. Background Art

[0002] Wear-resistant composite pipes have excellent wear resistance, can resist the wear of various rough surfaces, and can keep the surface smooth for a long time under the scouring of high-speed fluids. They also have strong corrosion resistance and can be used for a long time in the environment of acid and alkali corrosive media without being corroded. In addition, they also have good pressure resistance and heat resistance, and can play a stable performance under high temperature and high pressure working conditions.

[0003] Thanks to the excellent performance of wear-resistant composite pipes, they have been widely used in many fields. The first is the mining industry, where there are often a lot of stones, ores and other materials to be transported and processed, which requires high wear resistance of pipes. Wear-resistant composite pipes can effectively prevent pipe wear and corrosion and extend service life. The second is the metallurgical industry, where high temperature and corrosive media often need to be handled during the metallurgical process. The excellent performance of wear-resistant composite pipes can play an important role in such environments.

[0004] When existing wear-resistant composite pipes are used in mining material transportation or the metallurgical industry, they are limited by the construction scene. The wear-resistant composite pipes that play a conveying role will inevitably turn. When the internal objects change their moving direction, the objects will have a hard impact with the inner wall of the wear-resistant composite pipe, resulting in a large degree of wear on the inner wall of the pipe at the turning point, which greatly shortens the service life.

[0005] Therefore, in view of this, the applicant has studied and improved the existing structural deficiencies and proposed a wear-resistant composite pipe with a long service life to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a wear-resistant composite pipe with a long service life, so as to solve the problem proposed in the above-mentioned background technology that due to the limitations of the construction scene, the wear-resistant composite pipe that plays a conveying role will inevitably have turning points, and when the internal object changes its moving direction, the object and the inner wall of the wear-resistant composite pipe will have a hard impact, resulting in a large degree of wear on the inner wall of the pipe at the turning point, thereby greatly shortening the service life.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wear-resistant composite pipe with a long service life, comprising a bend pipe applied at a turning point of a pipeline, a first flange and a second flange being fixed at both ends of the bend pipe, a ceramic lining at an outer bend being bonded to the inside of the bend pipe, and a ceramic lining reinforcement block being bonded to the outer bend side of the ceramic lining at the outer bend;

[0008] The end of the curved pipe is connected to the straight pipe through the cooperation of the first flange and the second flange;

[0009] The outer wall of the curved pipe is fixed with a corner fixing piece for closing the ceramic lining piece at the outer bend and the ceramic inner lining reinforcement block.

[0010] Furthermore, the inner circumference of the straight pipe and the inner circumference of the straight portion of the curved pipe are both constructed with guide grooves, and guide strips fixed to the outer circumference of the ceramic lined pipe are fitted in the guide grooves.

[0011] Furthermore, a locking block with the same rotation direction is fixed on the outer periphery of the first flange.

[0012] Furthermore, the outer periphery of the second flange is configured with a positioning groove adapted to the locking block, and when the locking block rotates to the edge of the positioning groove after the first flange and the second flange are fitted together, the bolt holes on the first flange and the second flange overlap.

[0013] Furthermore, the outer periphery of the ceramic lined pipe is configured with a plurality of friction surfaces which are distributed at equal intervals and are located between the guide strips.

[0014] Furthermore, the turning angle of the elbow can be set to thirty degrees.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can strengthen the part where the pipe transfer angle changes by arranging a ceramic lining reinforcement block at the outer bend of the elbow and a ceramic lining at the outer bend. By increasing the thickness of the wear-resistant ceramic lining at this part, the service life of the outer bend side of the inner wall of the elbow can be effectively extended. When only the ceramic lining is worn, it is convenient to replace it, thereby reducing the use cost of the pipeline.

[0017] 2. The utility model facilitates the connection of the bent pipe with the straight pipe connected to its end due to the structural design of the first flange and the second flange, and can be quickly positioned, installed and fixed. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0025] The first flange 8 and the second flange 9 are fixed at both ends of the curved pipe 5 respectively, and the first flange 8 or the second flange 9 is fixed at the end of the straight pipe 1. When the straight pipe 1 is connected to the curved pipe 5, if the end of the straight pipe 1 is the first flange 8, the straight pipe 1 is connected to one end of the second flange 9 of the curved pipe 5; if the end of the straight pipe 1 is the second flange 9, the straight pipe 1 is connected to one end of the first flange 8 of the curved pipe 5, and through the cooperation of the positioning groove 91 and the locking block 81, it is convenient to position, fit and fix the first flange 8 and the second flange 9.

[0026] Thanks to the designed ceramic lining 10 and ceramic inner lining reinforcement block 6 at the outer bend, while forming a continuous linear guide surface, the thickness of the inner wall of the elbow 5 can be effectively increased, thereby greatly extending the wear cycle of the outer bend side of the elbow 5, thereby extending the service life of the pipeline.

[0027] As mentioned above, the inner circumference of the straight pipe 1 and the inner circumference of the straight portion of the curved pipe 5 are both constructed with guide grooves, and the guide strips 4 fixed to the outer circumference of the ceramic lined pipe 2 are fitted in the guide grooves.

[0028] Under the action of the guide groove and the guide strip 4 , the ceramic lined pipe 2 can be conveniently positioned and inserted into the inner periphery of the straight pipe 1 or the inner periphery of the straight part of the curved pipe 5 .

[0030] When the first flange 8 and the second flange 9 are fitted together and fixed, it can be known whether the first flange 8 and the second flange 9 are positioned and fitted together by observing whether the bolt holes are completely overlapped.

[0031] As mentioned above, the outer periphery of the ceramic lined pipe 2 is structured with a plurality of friction surfaces 3 which are distributed at equal intervals and are located between the guide strips 4 .

[0032] Under the action of the friction surface 3, the adhesion effect between the ceramic lined pipe 2 and the inner periphery of the straight pipe 1 can be improved under the action of the coupling agent.
