Abstract
The utility model discloses a novel superfine mill wind-guiding ring that stands belongs to and founds mill technical field. The vortex mill comprises an annular shell with a taper, wherein the inner side wall of the annular shell is fixedly connected with a plurality of air deflectors which are uniformly distributed, the plurality of air deflectors are obliquely arranged along the axis direction of the annular shell and are used for forming a cyclone vortex in a grinding cavity, and the outer side wall of the annular shell is fixedly connected with a fixing flange. The utility model discloses an angle that wind-guiding ring, aviation baffle changed wind makes it form the vortex of whirlwind formula in grinding the intracavity, and the material after will grinding fully brings into the subregion on awl fill body upper portion to prevent to grind effectively and promote grinding efficiency.
Description
Technical Field
The utility model relates to a novel superfine mill wind-guiding ring that stands belongs to and stands mill technical field.
Background
The conventional superfine vertical mill wind guide ring is a circular ring, the wind direction of a wind channel tends to be straight in the working process, a cyclone vortex is difficult to form, ground materials at two wind inlets are easily brought into a grading area at the upper part of the cone body under the drive of a large amount of wind, but the wind speed and the wind quantity of the materials at the other side are small due to wind resistance, the ground materials are difficult to be completely brought into the grading area at the upper part of the cone body, and thus the ground materials are not brought into the grading area partially, and the grinding efficiency is reduced.
Disclosure of Invention
The utility model discloses the technical problem that will solve lies in: the utility model provides a novel superfine vertical mill wind-guiding ring, it has solved the material after partly grinding and has not been brought the subregion into, reduces the problem of grinding efficiency.
The utility model discloses the technical problem that will solve takes following technical scheme to realize:
the utility model provides a novel superfine mill wind-guiding ring immediately, is including taking conical annular casing, the inside wall fixedly connected with a plurality of evenly distributed's of annular casing aviation baffle, it is a plurality of the aviation baffle all sets up along the axle center direction slope of annular casing for at the vortex of grinding the intracavity formation whirlwind formula, the lateral wall fixedly connected with mounting flange of annular casing.
As a preferred example, the angle of the air deflector is the same as the rotation direction of the vertical mill.
As a preferred example, the top or the bottom of the annular shell is provided with a plurality of notches.
The utility model has the advantages that: the utility model discloses an angle that wind-guiding ring, aviation baffle changed wind makes it form the vortex of whirlwind formula in grinding the intracavity, and the material after will grinding fully brings into the subregion on awl fill body upper portion to prevent to grind effectively and promote grinding efficiency.

FIG. 3 is a schematic structural view of the present invention installed on a vertical mill;
fig. 4 is the position structure schematic diagram of the utility model and the host air port of the vertical mill.
In the figure: the vertical mill comprises a main machine shell 1, a cone bucket body 2, a grinding roller 3, an air guide ring 4, an annular shell 41, an air guide plate 42, a fixed flange 43, a notch 44, a grinding disc seat 5, a main machine air port 6, a reduction box 7 and a vertical mill body 8.
Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.
As shown in fig. 3 and 4, the superfine vertical mill comprises a main machine housing 1 and a vertical mill body 8, wherein a conical hopper body 2 and a plurality of grinding rollers 3 are arranged on the main machine housing 1, and a reduction box 7, a grinding disc seat 5 and a plurality of main machine air inlets 6 are arranged on the vertical mill body 8, as shown in fig. 1 and 2, the novel superfine vertical mill air guide ring is arranged between the main machine housing 1 and the vertical mill body 8 and comprises an annular housing 41 with a taper, the inner side wall of the annular housing 41 is fixedly connected with a plurality of uniformly distributed air guide plates 42, the plurality of air guide plates 42 are all obliquely arranged along the axis direction of the annular housing 41, so that the angle of the air guide plates 42 is the same as the rotation direction of the vertical mill and is used for forming a cyclone-type vortex in a grinding cavity, the outer side wall of the annular housing 41 is fixedly connected with a fixed flange body 43, and the main machine housing 1, the air guide ring 4 and the vertical mill body 8 are fixed together through bolts; in addition, a plurality of gaps 44 are formed in the top or the bottom of the outer annular shell 41, and the gaps 44 are clamped on the protruding blocks of the main machine shell 1 or the vertical mill body 8 and used for quickly positioning the air guide ring 4, so that the installation position of the air guide ring is accurate, and ground materials are fully brought into a grading area on the upper portion of the cone body 2.
The working principle is as follows: when the grinder is used, the angular direction of the air deflector 42 is the same as the rotation direction of the grinder, in the working process, the reduction gearbox 7 drives the grinding disc seat 5 to rotate clockwise, air entering the grinder from the main machine air port 6 passes through the air deflector 42 of the air deflector ring 4, enters the grinding cavity at a certain angle along the rotation direction of the grinder, and forms a cyclone vortex in the grinding cavity, so that materials ground by the three grinding rollers 3 can be favorably brought into the classification area on the upper part of the cone bucket body 2.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the present invention, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
