Abstract
The utility model relates to a coal mill nozzle, which includes a nozzle body, wherein a movable seal ring assembly is mounted at the front end inside the nozzle body; a stationary seal ring assembly is mounted at the inner chamber of the nozzle body; adjusting rings are welded inside the stationary seal ring; an inner movable ring is mounted inside the movable seal ring assembly; the stationary seal ring assembly is divided into an upper stationary seal ring and a lower stationary seal ring; the movable seal ring assembly, the stationary seal ring assembly and the nozzle body are fixed through bolts. The utility model has the benefits that the coal mill nozzle provided by the utility model has the advantages of high convenience for maintenance, shortened maintenance time and facilitation of smooth falling of coal gangue, and the like.
Description
Technical field
The utility model relates to a kind of coal pulverizer nozzle.
Background technology
Coal pulverizer, have the models such as vertical pulverizer, high-pressure overhang roll mill, middling speed micropowder grinding, super-pressure trapezoidal mill, Raymond mill, and coal pulverizer is by coal crusher and wears into the machinery of coal dust, and it is the important auxiliary equipment of coal-powder boiler.The coal-grinding process is that coal is broken and the ever-increasing process of surface area.Increase new surface area, must overcome the intermolecular adhesion of solid, thereby need consumed energy.Coal by being ground into coal dust, is mainly by crushing, smashes and grind three kinds of modes and carry out in coal pulverizer.Nozzle is that the existing nozzle maintenance difficult of indispensable vitals in coal pulverizer, repair time are long, gangue is scattered difficulty.
The utility model content
The purpose of this utility model is to provide a kind of coal pulverizer nozzle, and to overcome at present, existing nozzle maintenance difficult, repair time are long, gangue is scattered the shortcomings such as difficulty.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of coal pulverizer nozzle, comprise nozzle body, and described nozzle body interior forward end is equipped with moving ring assembly, and static components is installed at nozzle body inner chamber place, and the static components internal welding is connected to adjustment ring, and moving ring assembly inside is equipped with interior rotating ring.
Further, described static components is divided into stationary ring and lower stationary ring.
Further, described moving ring assembly, static components and nozzle body are bolted.
The beneficial effects of the utility model are: a kind of coal pulverizer nozzle that the utility model provides, have easy to maintenance, shorten the repair time, be convenient to the smoothly advantage such as whereabouts of gangue.
The accompanying drawing explanation
Below with reference to the accompanying drawings the utility model is described in further detail.
Fig. 1 is the cutaway view of the described a kind of coal pulverizer nozzle of the utility model embodiment;
Fig. 2 is the static components structural representation of the described a kind of coal pulverizer nozzle of the utility model embodiment;
Fig. 3 is the moving ring assembly structural representation of the described a kind of coal pulverizer nozzle of the utility model embodiment.
In figure:
1, nozzle body; 2, static components; 3, moving ring assembly; 4, inner chamber; 5, adjustment ring; 6, interior rotating ring.
The specific embodiment
As Figure 1-3, the described a kind of coal pulverizer nozzle of the utility model embodiment, comprise nozzle body 1, described nozzle body 1 interior forward end is equipped with moving ring assembly 3, static components 2 is installed at nozzle body 1 inner chamber place, static components 2 internal weldings are connected to adjustment ring 5, and moving ring assembly 3 inside are equipped with interior rotating ring 6, and described static components 2 is divided into stationary ring and lower stationary ring.Described moving ring assembly 3, static components 2 are bolted with nozzle body 1.
The described a kind of coal pulverizer nozzle of the utility model embodiment, the inner moving ring assembly 3 of installing of nozzle body 1 is with static components 2 and in static components 2 interior welds adjustment rings 5.Static components 2 is combined by the upper stationary ring of segmentation and the lower stationary ring of segmentation.The upper stationary ring of rapid wear is convenient in this design, in the situation that the coal pulverizer maintenance in mill of not disintegrating is changed.And nonabradable lower stationary ring can continue to use, thereby reduce the expense of static components 2 maintenance and spare unit, shorten inspection and repair shop and use the time, lower stationary ring endoporus lower surface, extend out in design, be convenient to gangue and fall smoothly and avoid it that bite occurs in dynamic and static ring to reaching this living problem by its generation.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation on its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
