Abstract
The utility model discloses a coal mill separator which comprises a separator body, a separator top cover, a dynamic separator and a guide baffle, wherein the separator body, the separator top cover, an end surface of the dynamic separator and an inner wall of the guide baffle are respectively welded with a metal clamping groove which is inserted into wear-resistant ceramics provided with cutting openings. The coal mill separator is high in bonding property, can resist high-strength vibration, is high in toughness, hardness and wear resistance, can save the energy loss, and improves the working efficiency; and therefore, the service life of the coal mill separator is greatly prolonged, the service time is prolonged, the maintenance cost is reduced, and the coal mill separator has an obvious economic benefit.
Description
Technical field
The utility model relates to a kind of coal-grinding equipment, specifically is a kind of separator for coal mill.
Background technology
Coal pulverizer is used for the grinding of high rigidity for a long time, and separator wearing and tearing wherein are very serious, and worn out phenomenon appears in local meeting, causes leaking coal, badly influences safety in production, and brings the hidden danger of catching fire.Therefore just must keep in repair even upgrade within a short period of time, not only influenced operating efficiency, more make cost increase greatly.
Summary of the invention
Goal of the invention: the purpose of the utility model is the deficiency to prior art, provides a kind of inwall wearability good separator for coal mill.
Technical scheme: in order to reach the foregoing invention purpose; The utility model is specifically realized like this: a kind of separator for coal mill; Comprise and separate body, separator top cover, dynamic separator and deflector apron; Separate on body, separator top cover, dynamic separator end face and the deflector apron inwall all being welded with the metal draw-in groove, the metal draw-in groove is inserted in the wear-resistant ceramic that has otch.
Wherein, the geometry of said wear-resistant ceramic otch is an isosceles trapezoid.
Wherein, have an assembly welding hole on the said metal draw-in groove.
Wherein, can scribble binding agents such as high temperature resistant glue between said metal draw-in groove and the wear-resistant ceramic.
In concrete the production, what directly contact with cinder is wear-resistant ceramic, therefore can avoid the direct wearing and tearing of separator, also only need get final product by the replacing wear-resistant ceramic when safeguarding.
Beneficial effect: the utility model is compared with traditional coal pulverizer, has high associativity, anti-high-intensity oscillation, high strength, high tenacity, high rigidity and high-wear resistance, and loss that can energy savings is increased work efficiency; Improve the service life of separator greatly, increased service time, reduced maintenance cost, had tangible economic benefit.
