Abstract
The utility model discloses a nozzle protector for an air mill, which belongs to parts of an air mill and comprises a cover. The cover is fixedly installed on a cylindrical body of the air mill and encircles a nozzle of the air mill to form a buffer air cabin, an air inlet arranged on the cover is connected to an air source, a material blocking device disposed inside the cover is used for stopping the nozzle of the air mill from being directly communicated with the air inlet of the cover. The protector resolves the technical problem that after the air mill stops running, materials entering an air path via the nozzle can cause abrasion of the nozzle and affect the service life of the nozzle. The protector has the advantages of simple structure and wide application in air mills.
Description
Technical field
The utility model relates to a kind of airslide disintegrating mill accessory, relates in particular to a kind of protective device of airslide disintegrating mill nozzle.
Background technology
The kind of airslide disintegrating mill has much in the market, flat, target formula is arranged, to spray formula, fluidized bed type airslide disintegrating mill, drives material by supersonic airstream and clashes, rubs, shears, and makes particle reach ultra-fine grinding.
All utilizing compressed air to carry out material by nozzle ejection supersonic airstream during these airslide disintegrating mill work pulverizes, but after crushed work stops, remaining material can enter gas circuit by nozzle in the pulverizing chamber, when restarting airslide disintegrating mill, high-speed compressed air can be carried material and be sprayed together, so just cause nozzle wear serious, influence the service life of nozzle.
The utility model content
Technical problem to be solved in the utility model is: a kind of airslide disintegrating mill nozzle guard device is provided, enters gas circuit to solve airslide disintegrating mill shutdown back material by nozzle, the wearing and tearing nozzle influences the nozzle technical problem in service life.
For solving the problems of the technologies described above, the technical solution of the utility model is: airslide disintegrating mill nozzle guard device, comprise cover body, described cover body is fixedly installed on the cylindrical shell of airslide disintegrating mill, described cover body forms the cushion gas storehouse around the nozzle of described airslide disintegrating mill, and described cover body is provided with and is used for the air inlet that is connected with source of the gas; Be provided with the resistance material device that the nozzle that is used to intercept described airslide disintegrating mill and the air inlet of described cover body directly communicate in the described cover body.
As a kind of improvement, described resistance material device comprises the backgauge groove, described backgauge groove is fixedly installed on the described nozzle, described backgauge groove forms the ligulate chamber that communicates with described nozzle with described nozzle, described ligulate chamber has upper opening, and described ligulate chamber communicates with described cushion gas storehouse from described upper opening.
As a kind of improvement, the nozzle of described airslide disintegrating mill and the air inlet of cover body are provided with in the same way.
Owing to adopted technique scheme, the beneficial effects of the utility model are: owing to be provided with cover body in the nozzle periphery, be connected with compressed air line, form the cushion gas storehouse, make compressed air enter and in the cushion gas storehouse, form gas storage in a small amount, help forming fluid bed more.Because the mouth mouth place of nozzle is provided with the backgauge groove; make when airslide disintegrating mill nozzle guard device stops crushed work; material accumulates in the ligulate chamber at mouth mouth place of nozzle; stop material to enter gas circuit effectively by the gas channel of nozzle; when starting airslide disintegrating mill once more; because it is big that the space in cushion gas storehouse becomes suddenly; make that start air pressure is smaller; the material that smaller air pressure will accumulate in the ligulate chamber is released; little to nozzle wear, avoided material to enter gas circuit after, high-speed compressed air can be carried material and be sprayed together; seriously cause nozzle abrasion, influence the service life of nozzle.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: 1, discharging opening, 2, cylindrical shell, 3, nozzle, 4, cover body, 5, the backgauge groove, 6, discharge valve, 7, charging aperture, 8, grader, 9, air inlet.
The specific embodiment
As shown in drawings, a kind of airslide disintegrating mill nozzle guard device comprises cover body 4, and described cover body 4 is fixedly installed on the cylindrical shell 2 of airslide disintegrating mill, described cover body 4 forms the cushion gas storehouses around the nozzle 3 of described airslide disintegrating mill, and described cover body 4 is provided with and is used for the air inlet 9 that is connected with source of the gas; Be provided with the resistance material device that the nozzle 3 that is used to intercept described airslide disintegrating mill and the air inlet 9 of described cover body 4 directly communicate in the described cover body 4.
Described resistance material device comprises backgauge groove 5, described backgauge groove 5 is fixedly installed on the described nozzle 3, described backgauge groove 5 forms the ligulate chamber that communicates with described nozzle 3 with described nozzle 3, and described ligulate chamber has upper opening, and described ligulate chamber communicates with described cushion gas storehouse from described upper opening.
The nozzle 3 of described airslide disintegrating mill is provided with in the same way with the air inlet 9 of cover body 4.
Its course of work is as follows:
General and the grader 8 of airslide disintegrating mill nozzle guard device is used, and the micro mist that pulverizing obtains is collected by the discharge of air-introduced machine air-flow.Material enters in the cylindrical shell 2 from charging aperture 7, through disperseing the back to fall, compressed air enters cover body 4 by gas circuit, form the cushion gas storehouse in the cover body 4, through nozzle 3 ejections, form supersonic airstream, because nozzle 3 is positioned at same aspect on cylindrical shell 2, some relative in twos to nozzle 3, supersonic airstream forms fluid bed in cylindrical shell 2, material clashes, rubs, shears after dropping to the fluid bed position, carries out ultra-fine grinding, under the effect of air inducing air-flow, separate the back through grader 8 and collect from discharging opening 1 discharge.When airslide disintegrating mill nozzle guard device stops crushed work; backgauge groove 5 stops material to enter gas circuit by nozzle 3 effectively; when starting airslide disintegrating mill once more; because it is big that the space in cushion gas storehouse becomes suddenly, make that start air pressure is smaller, the material that smaller air pressure will accumulate in the ligulate chamber is released; after having avoided material to enter gas circuit; high-speed compressed air can be carried material and be sprayed together, causes nozzle 3 wearing and tearing, influences the service life of nozzle 3.The large granular materials of Fen Suiing is not discharged by the discharge valve 6 of cylindrical shell 2 bottoms, collects.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the present utility model.
