Problems solved by technology

[0006] ④The materials conveyed by concrete transportation often have poor fluidity, which increases the pressure on the pipe elbow and also intensifies the wear on the pipe elbow
[0007] The traditional steel elbow has a relatively short service life due to its limited wear resistance, with an average life of 2-3 months (transporting 20,000 cubic meters of material)

Embodiment Construction

[0017] Referring to Fig. 1, Fig. 2 and Fig. 3, a wear-resistant ceramic lining 4 is provided on the inner wall of the seamless elbow body 1, and the wear-resistant ceramic lining 4 is spliced ​​by a plurality of wear-resistant ceramic sheets 2, that is, wear-resistant ceramic sheets 2. Wedge splicing in the circumferential direction to form a wear-resistant ceramic lining ring 5 adapted to the inner wall of the seamless elbow body 1, and multiple groups of wear-resistant ceramic lining rings 5 ​​are axially connected and bent to form a wear-resistant ceramic lining adapted to the seamless elbow body 1 The lining 4 is provided with a first retaining ring 6 and a second retaining ring 7 at the two ports of the seamless elbow body 1 to block the wear-resistant ceramic lining 4 respectively.

[0018] Referring to Fig. 1, Fig. 2 and Fig. 3, the present invention greatly improves the wear resistance of the iron and steel delivery pipeline. The wear-resistant ceramic lining 4 has goo...

Abstract

The invention discloses an assembly ceramic abrasion-resistance bend head, wherein, the inner wall of seamless bend head main body (1) is arranged with an abrasion-resistance ceramic liner (4) assembled from several abrasion-resistance ceramic plates (2) that assembles the abrasion-resistance ceramic plates in wedge shape into one abrasion-resistance ceramic liner ring (5) engaged with the inner wall of main body (1); several liner rings (5) are axially bended and connected to form the abrasion-resistance ceramic liner (4) engaged with the main body (1); two ends of main body (1) are respectively arranged with the baffle rings of abrasion-resistance ceramic liner (4); the high-temperature resistant inorganic adhesive (3) is filled between the inner wall and the abrasion-resistance ceramic liner (4). The invention can avoid reduction and deformation, with simple structure and low cost.

Description

technical field [0001] The invention relates to a pipeline elbow, which is mainly aimed at the pipeline elbow for conveying concrete materials. Background technique [0002] During the process of concrete delivery by concrete delivery trucks, there has always been a troublesome problem, that is, severe wear and tear of equipment. Due to the harsh working environment of concrete conveying vehicles, it is usually: [0003] ① The conveying height is large, generally 20-400 meters high; [0004] ②Pipeline equipment bears high pressure during material transportation; [0005] ③ Concrete often contains large particles of limestone and river pebbles, and the hardness of the material is high, which will seriously wear the pipe elbow; [0006] ④ The materials conveyed by concrete transportation often have poor fluidity, which increases the pressure on the pipe elbow and also intensifies the wear on the pipe elbow. [0007] The traditional steel elbow has a relatively short servic...
