Spiral seam lining for improving wear resistance of cyclone or cyclone deduster

Abstract

The invention relates to a spiral seam lining for improving the wear resistance of a cyclone or a cyclone deduster. The spiral seam lining is positioned in the cyclone or the cyclone deduster, and is formed by a cylinder body (1) and a cone body (2), the outer wall of the cylinder body (1) and the cone body (2) is vertically welded with rib plates (3), the width of the rib plates is 5-40 mm, the thickness of the rib plates is 2-10 mm, the quantity of the rib plates is 3-5, the cylinder body (1) and the cone body (2) are provided with a spiral seam (4), the width of the spiral seam is 5-40 mm, the spiral seam screws in a clockwise downward manner until the spiral seam reaches the bottom of the cone body (2), the diameters of the cylinder body (1) and the cone body (2) of the lining are 10-80 mm smaller than the diameters of the cylinder body and the cone body of the cyclone or the cyclone deduster, and are two times the width of every outer wall welding rib plate (3), the height of the lining is same to the height in the cyclone or the cyclone deduster, and the cone angle of the lining is same to that of the cyclone or the cyclone deduster; and the upper portion of the cylinder body (1) is provided with an elliptical inlet (5) which is connected with the inlet of the cyclone or the cyclone deduster. The spiral seam lining has the advantages of use of common making materials, simple structure, simple process, low cost, high wear resistance, convenience in replacement, and long service life.

Description

technical field [0001] The invention relates to the technical field of cyclones and cyclone dust collectors, in particular to a spiral seam lining for improving the wear resistance of cyclones or cyclone dust collectors. Background technique [0002] Cyclone, also known as hydrocyclone, is a classification device for separating heterogeneous phase mixtures. It can be used to complete various operations such as liquid clarification, solid phase particle washing, liquid degassing and sand removal, solid phase particle classification and classification, and separation of two immiscible liquids. [0003] The working principle of the cyclone is relatively simple, mainly using the principle of centrifugal force. Under the action of pressure, the ore pulp enters the shell along the tangential direction through the ore feeding pipe, and makes a rotary motion in the shell. The coarse particles in the ore pulp are subjected to a large centrifugal force and close to the wall of the ve...

AI Technical Summary

Problems solved by technology

Under the conditions of low temperature, small particle size, low hardness and round particle shape, its wear resistance is better; however, at high temperature, coarse particle size and high hardness, Under the condition of sharp grain shape, its wear resistance is poor

When using ordinary carbon rib plates to make the cyclone shell, no matter whether it is made of inorganic non-metallic materials such as cast stone, silicon carbide, and alumina ceramics, or organic materials such as wear-resistant rubber and polyurethane are used as wear-resistant linings, There are large differences in mechanical properties and thermal stability between the shell and the lining materials, which will also cause the lining to be easily deformed and fall off, which will seriously affect the classification and separation performance and service life of the cyclone or cyclone dust collector

[0007] From the above discussion, it can be seen that although a lot of research has been done on wear-resistant materials, the facts show that the wear problem of cyclone or cyclone dust collector still exists.
