Abstract
The utility model discloses a kind of separate type air intake spiral case for outstanding rod flour mill, comprise air intake spiral case body, described air intake spiral case body comprise coaxially place with outstanding rod flour mill support etc. the spiral case housing of radius arc structure, the below of described spiral case housing is provided with support; On described spiral case case inside wall, equilibrium is provided with the flexible guide duct that multiple and described spiral case housing axis forms angle, and described flexible guide duct is connected with described outstanding rod flour mill support by bolt.The utility model has the advantage of and the multiple flexible guide duct of spiral case housing by circumference uniform distribution is connected with suspension mill support by bolt, make to be formed between spiral case housing and suspension mill support to be flexible coupling, spiral case housing is not by the impact of body vibration, spiral case housing can not be made impaired, extend the service life of spiral case housing.
Description
Technical field
The utility model relates to for outstanding rod flour mill, especially relates to a kind of separate type air intake spiral case for outstanding rod flour mill.
Background technology
Suspension mill is widely used in the grinding of the mineral products materials such as metallurgy, building materials, chemical industry, mine, and the abrasive body that suspension mill is made up of grinding roller and bull ring carries out pulverizing grinding to the material entering milling zone.During work, suspension mill main shaft rotates, and drives grinding roller grinding roller while bull ring revolution to carry out autobiography.Grinding roller, by reaction force acts when centrifugal force and pressing materials, causes power throughout to stack up incomplete equilibrium, causes body vibration.Existing air intake spiral case support forms Hard link by the body of bolt and suspension mill, and when suspension mill works, body vibration passes to air intake spiral case, and long-time vibration can cause air intake spiral case housing to occur crack, and air intake spiral case housing is impaired.
Summary of the invention
The purpose of this utility model is to provide a kind of and can overcomes vibration and cause spiral case housing to occur the separate type air intake spiral case for outstanding rod flour mill in crack.
For achieving the above object, the utility model can take following technical proposals:
Separate type air intake spiral case for outstanding rod flour mill described in the utility model, comprise air intake spiral case body, described air intake spiral case body comprise coaxially place with outstanding rod flour mill support etc. the spiral case housing of radius arc structure, the below of described spiral case housing is provided with support; On described spiral case case inside wall, equilibrium is provided with the flexible guide duct that multiple and described spiral case housing axis forms angle, and described flexible guide duct is connected with described outstanding rod flour mill support by bolt.
The cross section of described spiral case housing is quadrilateral structure, and from air inlet, width is identical backward, reduces highly gradually.
Four angles of described spiral case housing cross-sectional are right angle or fillet, and can two angles be also fillet above, lower two angles be right angle.
The utility model has the advantage of and the multiple flexible guide duct of spiral case housing by circumference uniform distribution is connected with suspension mill support by bolt, make to be formed between spiral case housing and suspension mill support to be flexible coupling, spiral case housing is not by the impact of body vibration, spiral case housing can not be made impaired, extend the service life of spiral case housing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 be Figure 1A-A to sectional view.
Detailed description of the invention
As Figure 1-3, separate type air intake spiral case for outstanding rod flour mill described in the utility model, comprise air intake spiral case body, this air intake spiral case body comprise with outstanding rod flour mill support 1 coaxial place etc. the spiral case housing 2 of radius arc structure, outstanding rod flour mill support 1 is regular polygon structure (is octagon structure in figure, also can be square, regular pentagon, regular hexagon or positive heptagon structure), the below of spiral case housing 2 is provided with support 3; Balancedly on spiral case housing 2 madial wall be provided with eight and form the flexible guide duct 4 of angle with spiral case housing axis, flexible guide duct 4 is connected with outstanding rod flour mill support 1 by connecting bolt 5.The cross section of this spiral case housing 2 is quadrilateral structure, and from air inlet, width is identical constant backward, reduces (spiral case housing 2 air inlet height is the highest, and tail height is minimum) highly gradually; Four angles of spiral case housing 1 cross section are right angle or fillet; Or upper two angles are fillet, lower two angles are right angle.
Spiral case housing 2 and outstanding rod flour mill support 1 are adopted separate type by the utility model, coaxial installation is separated with support 1 by spiral case housing 2, flexible guide duct 4 by circumference uniform distribution between spiral case housing 2 with support 2 is connected, this mode that is flexible coupling can be isolated body vibration and be conducted on spiral case housing 2, spiral case housing 2 is not affected by body vibration, extends the service life of spiral case housing 2.
