Wear-resistant cyclone and manufacturing method thereof
The invention discloses a wear-resistant cyclone and a manufacturing method thereof. The cyclone comprises a cylindrical section and a conical section, wherein the cylindrical section is provided with a feeding port, the cylindrical section and the conical section each comprise a shell layer, a bonding layer and a lining layer which are connected in sequence, and a first wear-resistant plate is arranged at the joint of the lining layer of the cylindrical section and the feeding port; and the first wear-resistant plate is made of silicon carbide or silicon nitride, and the lining layers are made of silicon carbide combined materials. The manufacturing method comprises the steps that the first wear-resistant plate coated with organic glue is placed in a preset position in a lining layer forming mold, a mixture is injected into the mold, and blanks of the lining layers are formed; and the organic glue is ablated, nitrogen or air is injected at high temperature to generate silicon nitride or silicon oxide to obtain the lining layers, and the lining layers are bonded to the shell layers. According to the wear-resistant cyclone and the manufacturing method thereof, the wear-resistant cyclone has a long service life and high reliability, also has a good grading effect and is easy to produce and machine, and the manufacturing cost can be controlled within a proper range.
本发明公开了一种耐磨旋流器及其制造方法，旋流器包括圆柱段和圆锥段，圆柱段上设有进料口，圆柱段和圆锥段均包括依次连接的外壳层、粘接层和内衬层，圆柱段的内衬层与进料口的接合部位设有第一耐磨板；第一耐磨板的材质为碳化硅或氮化硅，内衬层为结合碳化硅材质。制造方法包括将涂有有机胶的第一耐磨板放入内衬层成形模具中的预定位置，将混合料注入模具中，形成内衬层的坯件；烧蚀有机胶，在高温下充入氮气或空气生成氮化硅或氧化硅，获得内衬层，将该内衬层与外壳层粘接。本发明提供的耐磨旋流器及其制造方法，在具有较长的使用寿命和较高的可靠性的同时，还有较好的分级效果，易于生产加工，制造成本能控制在合适范围内。
