AI Technical Summary
In existing high-efficiency dust separation devices for cyclone dust collectors in air classifiers, the welding connection between the conical tube and the straight tube leads to cumbersome disassembly and assembly, affecting maintenance efficiency and production progress.
The connection method, which combines a limiting mechanism with an extended screw and bolts, along with a sealing rubber ring design, enables rapid positioning and locking of the tapered tube and the straight tube, while ensuring a tight seal.
It simplifies the assembly and disassembly process of the tapered tube, prevents material leakage, ensures stable internal pressure of the equipment, and ensures the continuous and stable operation of efficient separation.
