Abstract
The utility model discloses a spraying pipe structure of an airflow crushing machine. The spraying pipe comprises a first material spraying pipe and a second material spraying pipe, wherein the first material spraying pipe is provided with an inner air ring branched pipe; the front end of the inner air ring branched pipe is fixedly connected with an inner air pipe; the second material spraying pipe is provided with an outer air ring branched pipe; the front end of the outer air ring branched pipe is fixedly connected with an outer air pipe; the front end of the inner air pipe is connected with the rear end of the second material spraying pipe by a flange. The spraying pipe structure disclosed by the utility model has the advantages that the spraying pipe is uniformly divided by spiral blades uniformly distributed at a spraying pipe head, materials are spirally fed into a next section of material spraying pipe along the inner wall, and simultaneously the role in supporting the inner air pipe and the material spraying pipes is also played, so that the stress on the welding part of a simple-ring branched pipe is reduced, the rigidity of the whole part is improved, the spraying effect is improved and the service life is long.
Description
Technical field
The utility model relates to crushing material equipment pipe fitting parts technical field, specifically belongs to airslide disintegrating mill nozzle structure.
Background technology
The jet pipe of airslide disintegrating mill is the key position of whole equipment, existing nozzle structure design is unreasonable, high velocity air from jet pipe through voltage stabilizing district, venturi, enter shrinking zone and penetrate from nozzle to diffusion district, be unfavorable for that nozzle provides steady pressure, jeting effect is poor, and nozzle interior structural rigidity is had relatively high expectations; General service life is shorter.
Utility model content
The purpose of this utility model has been to provide airslide disintegrating mill nozzle structure, the helical blade that jet pipe is evenly arranged in nozzle head place by these separates uniformly, and send into next section of stuff-spraying pipe along spiral inner wall, simultaneously, also play the effect of supporting interior airduct and stuff-spraying pipe, be in charge of the stressed of weld thereby reduced simple ring, increased the rigidity of whole parts, improve its jeting effect.
The technical solution adopted in the utility model is as follows:
Airslide disintegrating mill nozzle structure, comprise the first stuff-spraying pipe and the second stuff-spraying pipe, the first described stuff-spraying pipe is provided with interior vane and is in charge of, interior vane is in charge of front end and is fixedly connected with interior airduct, the second described stuff-spraying pipe is provided with outer vane and is in charge of, outer vane is in charge of front end and is fixedly connected with outer airduct, and described interior airduct front end is connected by flange with the second stuff-spraying pipe rear end.
The first described stuff-spraying pipe and the tube head part of the second stuff-spraying pipe are all welded with spiral blade.
Described spiral blade tapering is identical with the tapering of interior airduct and outer airduct.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The helical blade that the utility model jet pipe is evenly arranged in nozzle head place by these separates uniformly, and send into next section of stuff-spraying pipe along spiral inner wall, simultaneously, also play the effect of supporting interior airduct and stuff-spraying pipe, thereby reduce simple ring and be in charge of the stressed of weld, increase the rigidity of whole parts, improved its jeting effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Referring to accompanying drawing, airslide disintegrating mill nozzle structure, comprise the first stuff-spraying pipe 1 and the second stuff-spraying pipe 2, the first stuff-spraying pipe 1 is provided with interior vane and is in charge of 3, interior vane is in charge of 3 front ends and is fixedly connected with interior airduct 4, the second described stuff-spraying pipe 2 is provided with outer vane and is in charge of 5, outer vane is in charge of 5 front ends and is fixedly connected with outer airduct 6, described interior airduct 4 front ends are connected by flange with the second stuff-spraying pipe 2 rear ends, the tube head part of the first stuff-spraying pipe 1 and the second stuff-spraying pipe 2 is all welded with spiral blade 7, and spiral blade tapering is identical with the tapering of interior airduct and outer airduct.These helical blades that are evenly arranged in nozzle head place separate uniformly, and send into next section of stuff-spraying pipe along spiral inner wall, simultaneously, also play the effect of supporting interior airduct and stuff-spraying pipe, be in charge of the stressed of weld thereby reduced simple ring, increased the rigidity of whole parts, improve its jeting effect.
