Embodiment 1

[0082] Specific embodiments of the present invention are provided below, and it should be noted that the present invention is not limited to the following specific embodiments, and all equivalent transformations done on the basis of the technical solutions of the present application all fall within the scope of protection of the present invention.

[0083] According to the above technical scheme, the cross-sections of the inlet and outlet of the S-shaped pipe elbow in this embodiment are both 320mm×250mm, and the thicknesses of the upper top plate, the lower bottom plate, the arc surface a and the arc surface b are all 0.5mm, and the S-shaped pipe elbow The elbow is formed by coupling two 90°pipe elbows. The inner radius of each 90°pipe elbow is 320mm and the outer radius is 640mm. Straight pipe section, a 2m long straight pipe section is connected to the outlet. According to the "Code for Design of Heating, Ventilation and Air Conditioning in Civil Buildings", the wind speed ...

Abstract

The invention discloses an anti-abrasion S-shaped pipe elbow and a wear-resistant treatment method for the elbow, comprising an upper top plate, a lower bottom plate, an arc surface a and an arc surface b; an upper top plate, a lower bottom plate, an arc surface a and an arc surface b The S-shaped elbow is obtained as four side enclosures; the upper top plate is the same as the lower bottom plate; the arc surface a is the same as the arc surface b; the upper top plate, the lower bottom plate and the arc surface a are all divided into high friction zone and medium friction force Wear-resistant materials with different wear-resistant thicknesses are used on the surfaces of the high-friction area and the medium-friction area in the elbow respectively. The elbow adopts different wear-resistant materials in the parts of different friction and shear forces, which can effectively resist the grinding of the pipeline by the material in the process of pneumatic conveying, so that different parts of the pipeline can be strengthened according to the degree of grinding, and at the same time save expensive materials , reduce the cost of the elbow.

Description

technical field [0001] The invention belongs to the field of industrial ventilation, and in particular relates to an elbow and a treatment method for the elbow, in particular to an S-shaped wear-resistant elbow and a wear-resistant treatment method for the elbow. Background technique [0002] In the process of conveying abrasive materials such as pneumatic and pumped slurry, because the conveying medium generally has the characteristics of high hardness, fast flow rate, and large flow rate, it will continue to impact, wear, and corrode the pipe wall for a long time during the conveying process. Fatigue the pipeline and gradually wear it out. Especially when the wear-resistant pipeline transports abrasive materials (such as ash, coal powder, ore powder, tailings, cement, etc.), there is a problem that the wear-resistant pipeline wears quickly, especially the bend of the pipeline. At the local resistance member such as the head, the collision between the material and the surr...
