Vortex type elbow structure for pneumatically conveying granules

The utility model relates to the technical field of pneumatic conveying of bulk materials, in particular to a vortex type elbow structure for pneumatic conveying of granules, which comprises an inlet pipeline and an outlet pipeline, the inlet pipeline is communicated with a first semi-arc piece, the outlet pipeline is communicated with a second semi-arc piece, and a sealed circular space is defined by the first semi-arc piece and the second semi-arc piece. The inlet pipeline and the outlet pipeline are respectively tangent to the circle of the cross section of the circular space, and the extension lines of the inlet pipeline and the outlet pipeline are intersected. According to the vortex type elbow structure for pneumatically conveying the particles, on the premise that elbow abrasion, fine powder, wiredrawing, noise and metal powder cross contamination are solved, multi-angle phase change can be achieved, and disassembly, assembly and use are more convenient. 本申请涉及气流输送散装物料的技术领域，主要涉及一种气力输送颗粒料的旋涡式弯头结构，包括入口管道和
