Embodiment Construction

[0031] A kind of ternary composite lining wear-resistant cyclone, see figure 1 , Figure 2, Figure 3 and Figure 4. It consists of an outer steel sleeve 1, an inner lining 2, a feed inlet 8, a grit chamber 6 and an overflow pipe 7. The outer steel sheath 1 is adopted as an ordinary steel sheath, and the inner lining layer 2 is composed of nanostructure wire mesh 3 , ceramic rod 4 and polyurethane 5 .

[0032] The ceramic rod 4 is made of alumina material with a diameter of 0.2-10mm, or tungsten carbide or silicon carbide, or other ceramic materials. The nanostructure wire mesh 3 is braided with medium carbon steel nanostructure wires with a diameter of 0.1-2.5 mm, and adopts Adiprene-1 type polyurethane.

[0033] The ceramic rods 4 are embedded in the meshes of the tightly laminated nanostructured wire mesh 3, the nanostructured wire mesh 3 is closely attached to the inner wall of the outer steel sleeve 1, the molten polyurethane 5 is poured on the wire mesh 3, and solidified ...

Abstract

A lined antiwear cyclone device with three-element composition is composed of external steel casing, an antiwear lining layer consisting of metallic wire net with nano structure, ceramic rods inlaid in the meshes of said net and polyurethane, feeding inlet, sand depositing mouth and overflow pipe. Its advantages are high hardness, strength, toughness, elasticity and antiwear nature and long service life.

Description

technical field [0001] The invention relates to a cyclone device and a preparation process, in particular to a composite material-lined wear-resistant cyclone and a preparation process thereof. Background technique [0002] The cyclone is a device that uses centrifugal force to classify and separate in a rotating flow. When the cyclone is running, the solid-liquid two-phase flow makes a strong rotational movement, and the inner wall of the cyclone is easily worn under the severe scouring of the two-phase flow. This will not only shorten the service life of the cyclone, but also reduce its classification and separation efficiency due to changes in the size of key parts, and change the overflow and bottom flow, thereby deteriorating the operating effect. Therefore, the cyclone has high requirements on wear resistance, and wear-resistant materials are generally used as linings. Usually the materials used to make the lining of the cyclone include alloy cast iron, ceramics and ...
