Abstract
The utility model provides a novel vertical mill nozzle ring device which comprises a nozzle of a nozzle ring, a nozzle wear-resistant plate, a nozzle ring cover board, a retention ring and a spreading plate. The nozzle is connected with the nozzle wear-resistant plate; the nozzle ring cover board is arranged on the nozzle ring; the retention ring is arranged at the position in the front of the nozzle ring and is adjacent to the nozzle ring cover board; the upper end of the spreading plate is welded at the top of the retention ring; the lower end of the spreading plate is parallel and level with the outer edge of the nozzle ring cover board. According to the utility model, the wear-resistant plate and the spreading plate have long service life so as to avoid frequent replacing the nozzle, the nozzle ring cover board and the retention ring; workload of replacing the wear-resistant plate and the spreading plate is low so as to gain time for shutdown overhauling in the tension production; relative to replacement of the nozzle, the nozzle ring cover board and the retention ring, replacement on the wear-resistant plate and the spreading plate can further reduce maintenance cost.
Description
Technical field
The utility model relates to a kind of vertical roll grinder, specifically the nozzle ring of vertical roll grinder.
Background technology
Nozzle ring is by forming according to the equally distributed some nozzles of circumferencial direction and a circle cover plate, and it is positioned at the mill outside at Vertical Mill middle part, relies on bolt to be arranged on vertical mill casing inside according to miter angle; In material grinding process, the mill that large granular materials is rotated is thrown to outside collet, through nozzle ring, fall into the recirculating system of Vertical Mill cavity of resorption from top to bottom, and outside hot blast changes wind direction by nozzle ring from bottom to top, drives small particles material to enter the powder system that selects of Vertical Mill epicoele.In nozzle ring inner side, near the position of mill, be stamped a circle nozzle ring cover plate, by adjusting the area of nozzle ring cover plate, change the wind speed of hot blast.
By mill, be thrown to the large granular materials outside collet, kinetic energy is large is thrown nozzle and nozzle ring cover plate outer edge, causes nozzle and the outer peripheral wearing and tearing of nozzle ring cover plate; In the gap of falling into nozzle ring cover plate inward flange and collet that kinetic energy is little, cause the wearing and tearing of nozzle ring cover plate inward flange and collet outer wall.After long-time wearing and tearing, cause the damage of nozzle and nozzle ring cover plate, Vertical Mill internal heat wind speed degree and change of the wind, it is stable that impact is produced.And long-time wearing and tearing meeting grinds a circle groove by collet outer wall, when serious, rub collet bolt, cause collet to come off, threaten the security of operation of Vertical Mill.
The workload of shutting down replacing nozzle, nozzle ring cover plate and collet is large, consuming time many, not only affect the continuous and steady operation of cement production enterprise rotary kiln, and the cost of changing is very high.
Utility model content
Utility model object: the purpose of this utility model is to provide a kind ofly can effectively avoid the Novel vertical mill nozzle ring device of large granular materials to the erosive wear of nozzle, nozzle ring cover plate and collet.
For achieving the above object, the technical solution of the utility model is a kind of Novel vertical mill nozzle ring device, comprises nozzle, nozzle wearing plate, nozzle ring cover plate, collet and the spreading disk of nozzle ring; Described nozzle and nozzle wearing plate join, nozzle ring cover plate is arranged on nozzle ring, collet is arranged on nozzle ring the place ahead and nozzle ring cover plate adjacent, the upper end of spreading disk is welded in the top of collet, the lower end of spreading disk is concordant with the outward flange of nozzle ring cover plate, guarantees not swipe with nozzle ring cover plate in spreading disk rotary course.
Described nozzle is provided with through hole, and nozzle wearing plate is provided with the counterbore suitable with through hole, and nozzle is connected by through hole, counterbore and bolt with nozzle wearing plate.
For increasing bonding strength, the top of described collet is also provided with strengthens the ribs that spreading disk upper end is connected with collet.
Beneficial effect: the long service life of the utility model wearing plate and spreading disk, avoided the frequent replacing to nozzle, nozzle ring cover plate and collet; The workload of changing wearing plate and spreading disk is little, for the shutdown maintenance in anxiety production gains time; With respect to changing nozzle, nozzle ring cover plate and collet, change wearing plate and spreading disk and more can reduce maintenance cost.
Accompanying drawing explanation
Fig. 1 is the utility model guide structure schematic diagram;
Fig. 2 be in Fig. 1 A-A to profile.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is made and being further illustrated.
As depicted in figs. 1 and 2, a kind of Novel vertical mill nozzle ring device, comprises nozzle 1, nozzle wearing plate 2, nozzle ring cover plate 3, collet 4 and the spreading disk 5 of nozzle ring; Nozzle 1 is provided with through hole, and nozzle wearing plate 2 is provided with the counterbore suitable with through hole, and nozzle 1 is connected by through hole, counterbore and bolt 6 with nozzle wearing plate 2.Nozzle ring cover plate 3 is arranged on nozzle ring, collet 4 is arranged on nozzle ring the place ahead and nozzle ring cover plate 3 adjacents, the upper end of spreading disk 5 is welded in the top of collet 4, and use ribs 7 to increase bonding strength, the lower end of spreading disk 5 is concordant with the outward flange of nozzle ring cover plate 3, guarantees not swipe with nozzle ring cover plate 3 in spreading disk 5 rotary courses.
By mill, be thrown to the large granular materials outside collet, on the large wearing plate of directly pounding nozzle of kinetic energy, what kinetic energy was little flows on the wearing plate of nozzle along spreading disk, then falls into the recirculating system of Vertical Mill cavity of resorption.
