Embodiment Construction
[0013] Such as figure 1 , figure 2 and image 3 As shown, expand the pipe diameter within the range of 45°~145° of the elbow 3, open a hole, and install a composite cover plate with the same curvature as the bend pipe at the hole. The composite cover plate is lined with patterned textured rubber 2 It is composed of a cover plate 1 that is closely attached to the outer periphery of the inner liner 2; in this embodiment, the inner diameter of the inner liner 2 is equal to the outer diameter of the elbow 3. The bent pipe 3 has the same pipe diameter as the connected straight pipe. The patterned textured rubber lining 2 has the same bending rate as the elbow, and the surface is regularly arranged patterned textures, and the material can be natural hard rubber, butyl rubber, neoprene rubber, nitrile rubber, etc. The patterned texture can be grooved, meshed, dotted, etc. In this embodiment, the rectangular groove-like texture is taken as an example, and the size can be adjusted...

Abstract
The invention discloses a solid material transporting elbow with a detachable and changeable liner, which belongs to wear-resistant elbows. The elbow is mainly applied to elbows in solid material transporting systems in the industries of steel, metallurgy, mines, coal mines, electric power, building and the like. The pipe diameter is expanded at a cylindrical curved part where the elbow is worn most severely, the expanding part can adopt a detachable structure, and a groove rubber liner is arranged. Through combined action of the expansion of the pipe diameter and the patterned texture rubber liner, the flow rate of materials is reduced, thus enabling part material granules to stay on the rubber liner, protecting the rubber liner and prolonging the service life of the elbow. Once being worn out, the rubber liner can be changed conveniently, thus saving the cost. The elbow has the beneficial effects of having simple structure and good processing property and being applied to elbows of any curved degree. The impact wear resistance is good, and changing and maintenance are convenient.
Description
technical field [0001] The invention relates to a conveying elbow, in particular to a conveying elbow with removable rubber lining for solid materials. It has the characteristics of high impact resistance, wear resistance, long life, and convenient maintenance and replacement. It is mainly used in elbows for solid material conveying systems in industries such as iron and steel, metallurgy, mining, coal mines, electric power, and construction. Background technique [0002] The application field of pipeline solid material conveying technology is becoming more and more extensive. For example, in many industrial fields such as metallurgy, coal, chemical industry, water conservancy, environmental protection, petrochemical industry, mining, electric power and geothermal energy, etc., it has been widely used in the transportation of ore, coal slurry, mud sand, limestone, solid waste, etc. The direct wear of the solid material on the pipe wall is very serious, often leading to prem...
