Description
Technical field
The present invention relates to swirl-flow devices and preparation technology, particularly a kind of composite material inner liner abrasive resistant cyclone and preparation technology thereof.
Background technology
Cyclone is to utilize centrifugal force to carry out the equipment of classification, separation in rotary current.In cyclone when operation,, the solid-liquid two-phase flow is done strong rotatablely moving, and under violent the washing away of two-phase flow, the cyclone internal face very easily weares and teares.This not only can shorten the service life of cyclone, and can reduce its classification, separative efficiency owing to the key position size changes, and changes overflow and underflow amount, thereby worsens operational effect.Therefore cyclone is had relatively high expectations to wearability, generally adopts high-abrasive material to do liner.Usually the material of making the cyclone liner has alloy cast iron, pottery and polyurethane material.Alloy cast iron liner cyclone wearability is relatively poor, and its service life is shorter, and Heavy Weight.Ceramic-lined cyclone is in light weight, mill property is also better, but because pottery is a fragile material, in transportation, installation, use, be hit and chipping scrapping easily, in running, be subjected under the situation of large scale material impact, ceramic-lined will be cracked and stop up cyclone, ceramic-lined in addition needs the, complex manufacturing, quality instability through high temperature sintering.Polyurethane cyclone is because in light weight, formability is good, rotproofness and wearability are higher and use to some extent in recent years, but find in using, polyurethane cyclone is when carrying the material of fine particle, result of use is better, when having the particle of bulky grain sharp corners in the material, because solid-liquid two-phase flow movement velocity height in the cyclone will be subjected to heavily stressed impact, cause the distortion of polyurethane liner easily, even tear in flakes, thereby not only influence classification, the separating effect of cyclone, and fragment also can stop up cyclone when serious, thus cause stopping production.In sum, homogenous material can't satisfy the combination property requirement to intensity, toughness, wearability, rotproofness, workability each side, must develop novel composite material and produce cyclone, could satisfy the production actual needs of every profession and trade to cyclone.
