Description

Technical Field

[0001] The invention relates to the field of pneumatic conveying pipeline accessories, in particular to a flexible gamma elbow used for a pneumatic conveying pipeline for granular materials. Background Art

[0002] In the pneumatic conveying system, when granular materials pass through the elbow, due to the friction between their own rigidity and the inner wall of the elbow, it is easy to cause the particles to break and draw, affecting product quality and system efficiency.

[0003] Specific solutions of existing technologies: Rigid elbows are conventionally used, and their inner walls are smooth to reduce friction. However, the rigid structure cannot effectively adapt to the flow characteristics of granular materials, and there is still a high risk of breakage and wire drawing.

[0004] The defects of the prior art: although the inner wall of the rigid elbow is smooth, the impact force and friction force on the particles at the turning point are relatively large, and the problem of particle breakage and wire drawing cannot be fundamentally solved.

[0005] Therefore, we provide a flexible γ elbow for a pneumatic conveying pipeline for granular materials to solve the above problems. Summary of the invention

[0006] 1. Technical issues to be resolved

[0010] A flexible liner, wherein the flexible liner is arranged on the inner wall of the rigid shell, the rigid shell is provided with a first inverted C-shaped portion and a first arc-shaped portion located between the first flange and the second flange, and a first bending portion is arranged between the first inverted C-shaped portion and the first arc-shaped portion of the rigid shell;

[0011] The flexible lining cooperates with the first inverted C-shaped portion to form a second inverted C-shaped portion, the flexible lining cooperates with the first arc-shaped portion to form a second arc-shaped portion, and the flexible lining cooperates with the first bent portion to form a second bent portion;

[0012] A feed cavity is formed between the first flange and the second arc-shaped portion, a discharge cavity is formed between the second flange and the second arc-shaped portion, and a buffer cavity is formed between the second bent portion and the second inverted C-shaped portion. The buffer cavity is located between the feed cavity and the discharge cavity.

[0013] The present invention provides a flexible elbow for a pneumatic conveying pipeline for particulate materials, which has a shape similar to a γ elbow. The inner wall of the elbow of the hard shell is provided with a flexible lining material layer, and the flexible lining material layer can reduce the rigid friction between the particulate material and the inner wall of the elbow during the turning process. The flexible lining material layer can be made of elastic materials such as rubber and silicone, and is fixedly connected to the inner wall of the elbow by an adhesive. When in use, the particulate material enters the feed cavity and buffer cavity of the elbow through pneumatic conveying, and the flexible lining material layer undergoes elastic deformation under the impact of the particles, thereby reducing the possibility of particle crushing and wire drawing. The γ-shaped structural design guides the material to form a reverse vortex flow in the buffer cavity of the second inverted C part, reducing the impact and friction between the material and the inner wall of the elbow, reducing the possibility of particle crushing and wire drawing from another perspective, and improving the quality of the product. Compared with traditional elbows with large curvature radius, it has small external dimensions and occupies less space, which is more conducive to pipeline layout. At the same time, the setting of the groove further optimizes the flow path of the granular material, the application of the reinforcing ribs enhances the structural strength and wear resistance of the elbow, and the flange connector facilitates the connection between the elbow and the conveying pipeline, thereby improving the overall efficiency and reliability of the system.

[0014] Furthermore, a plurality of grooves are provided on the flexible lining, and the grooves are distributed along the bending direction of the inner wall of the rigid outer shell. The grooves can guide the flow of the granular material, further reducing the friction contact area between the particles and the inner wall of the elbow, thereby reducing the risk of breakage and wire drawing.

[0015] Furthermore, the outer wall of the rigid shell is provided with oil reinforcing ribs, the reinforcing ribs are made of metal material, and the reinforcing ribs are connected to the outer wall of the rigid shell by welding or bolts.

[0016] Furthermore, sealing gaskets are provided on the first flange and the second flange.

[0018] Furthermore, the angle between the inclined shell wall on the rigid shell and the first flange is greater than 90°.
