Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] as attached figure 1 As shown, a rubber pipe elbow for slurry transportation includes a straight pipe part 1 and a bent part 2, and the pipe walls of the straight pipe part 1 and the bent part 2 are sequentially formed from the outer rubber layer 11 to the outer cord layer from the outside to the inside. 12. Composed of steel wire layer 13, inner cord layer 14 and inner rubber layer 15. After the above-mentioned layers are combined, they are vulcanized to form a whole. The outer cord layer 12 and the inner cord layer 14 are formed by calendering of chemical fiber fabric and rubber. When making, the surface of the inner rubber layer 15 is now applied to the inner cord layer 14, and then the surface of the inner cord layer 14 is In the formation of spiral winding, the steel wire is wound on the surface of the inner cord layer 14 to form a steel w...

Abstract

The invention relates to a slag pulp conveying device, provides a slag pulp conveying rubber pipe bend and aims to solve the technical problem of impact and proneness to damages of conveying pipe bend portions in a slag pulp conveying process. The slag pulp conveying rubber pipe bend comprises straight pipe portions and a bent portion and is characterized in that the pipe wall of each of the straight pipe portions and the bent portion is integrally formed by vulcanization of an outer rubber layer, an outer cord thread layer, a steel wire layer, an inner cord thread layer and an inner rubber layer sequentially from outside to inside, wherein the steel wire layer is spirally wound onto the surface of the inner cord thread layer to cover the same. By adoption of the structure, the slag pulp conveying rubber pipe bend has the advantages that impact resistance and corrosion resistance are greatly improved, service life is prolonged evidently, and applicability to extremely severe mine environments is realized.

Description

technical field [0001] The invention relates to a slurry conveying device, in particular to a slurry conveying rubber [0002] Hose elbow. Background technique [0003] At present, the slurry transportation in mineral processing, clean coal preparation, power plant, steel and cement industries requires special pipelines with high wear resistance, flexibility and shock absorption characteristics for transportation. During the conveying process of slurry, the impact of slurry on the pipeline is most obviously manifested in the impact on the elbow part, because the steel stamping elbow is mostly used in the elbow part or in the steel stamping elbow The lining rubber layer is added, and under the condition of high flow rate, the continuous impact of the slurry on the elbow will cause the elbow to be easily worn and broken. Contents of the invention [0004] In order to overcome the current technical problems of the impact on the elbow of the conveying pipe and the vulnerabil...
