The mining wear-resistant elbow according to claim 6, wherein: the two ends of the slow flow plate (2) are twisted and offset by sixty degrees, three slow flow plates (2) distributed at equal intervals are arranged on the first pipe body (101) and the second pipe body (102), and the twisting and offset directions of the slow flow plates (2) on the first pipe body (101) and the second pipe body (102) are the same.
8. The method for manufacturing the mining wear-resistant elbow according to any one of claims 1 to 7, comprising the following steps:
s1, producing a first pipe body (101) and a second pipe body (102) by a die casting mode, polishing the first pipe body (101) and the second pipe body (102), simultaneously arranging bolt perforation at corresponding positions on a connecting edge plate (1015) of the first pipe body (101) and the second pipe body (102), arranging bolt perforation on a first flange plate (1016) and a second flange plate (1017) at two ends of the first pipe body (101) and the second pipe body (102), spraying antirust paint on outer walls of the first pipe body (101) and the second pipe body (102), and drying after standing for a period of time;
s2, cutting a metal plate with a proper thickness into the size of a slow flow plate (2), forming evenly distributed perforations (201) on the plate, polishing the perforated plate to remove burrs and burrs, bending and twisting the plate to a required shape by using bending equipment after polishing, finishing processing of the slow flow plate (2), welding the slow flow plate (2) to the installation positions on the inner walls of the feeding sections (1013) on the first pipe body (101) and the second pipe body (102), and polishing the welding positions after welding;
s3, weighing 40-50 parts of silicon carbide ceramic particles, 50-60 parts of silicon nitride ceramic particles, 5-12 parts of submicron zirconia and 5-12 parts of binder according to parts by weight, and putting the mixture into a container for uniformly mixing to obtain a mixed material; pouring the mixed materials into different moulds for molding to obtain a prefabricated part A, a prefabricated part B and a prefabricated part C; placing the prefabricated part A, the prefabricated part B and the prefabricated part C into an atmosphere furnace, sintering for 30-50 min at 1100-1300 ℃, and quenching and tempering to obtain a first substrate, a second substrate and a reinforcing plate; placing the first base plate, the second base plate and the reinforcing plate into a casting mold, melting a metal material, pouring the melted metal material into a porous ceramic matrix, cooling to form a metal ceramic composite wear-resistant lining plate, completing the production of the wear-resistant lining plate (3), and grinding the inner side surface of the wear-resistant lining plate (3) into a frosted surface;
s4, finally, the produced wear-resistant lining plate (3) is installed in the installation groove (1014) on the first pipe body (101) and the second pipe body (102), a matched sealing gasket is installed between the connection edge plates (1015) which are mutually abutted by the first pipe body (101) and the second pipe body (102), and then the first pipe body (101) and the second pipe body (102) are stably connected together by utilizing bolts to penetrate through bolt holes in the connection edge plates (1015), so that the production of the whole elbow can be completed.
