Description
Technical field
The present invention relates to raymond mill, and in particular to the suspension strut structure of its grinding roller.
Background technology
Raymond mill is one of widest equipment of nonmetallic mineral processed and applied, and grinding roller is most heavy in raymond mill
The disintegrating mechanism wanted.Grinding roller suspension strut structure includes the main shaft of raymond mill, and grinding roller supporting rack, grinding roller are connected with main shaft
Grinding roller link is hinged with by hinge shaft on supporting rack, grinding roller connecting shaft, grinding roller connecting shaft lower end are connected with grinding roller link
It is connected with grinding roller, hinge shaft is located at the outside in the axle center of grinding roller connecting shaft, and the axle center of grinding roller connecting shaft and the axle center of main shaft are connected with the heart
The axial line of line and hinge shaft is mutually perpendicular to.Since hinge shaft is located at the outside in the axle center of grinding roller connecting shaft, tactical diameter is larger, causes
Existing Raymond mill cylinder is generally larger, to ensure the conveying material wind speed in cylinder, it is necessary to increase power of fan, cause energy
The waste in source.Further, since the axle center of grinding roller connecting shaft and the line of centres in axle center of main shaft and the axial line of hinge shaft are mutually perpendicular to,
When raymond mill works, grinding roller rotates in bull ring, its swaying direction is consistent with centrifugation force direction, when grinding roller crushes
During material, the counter-force direction that grinding roller flour material is subject in the horizontal plane can produce angle with the swaying direction of grinding roller, by this shadow
Ring, grinding roller produces the sharp pounding of tangential direction, reduces the service life of equipment at work.
The content of the invention
One of the technical problem to be solved in the present invention is to be directed to the above-mentioned waste defect for causing the energy, there is provided a kind of Raymond mill
The suspension strut structure of powder machine grinding roller, so that Raymond mill barrel diameter reduces, so as to reduce system institute required airflow, reduces the energy and disappears
Consumption.
In order to solve the above technical problems, the present invention provides a kind of suspension strut of such as raymond mill grinding roller of lower structure
Structure, includes the main shaft of raymond mill, is connected with grinding roller supporting rack on main shaft, and mill is hinged with by hinge shaft on grinding roller supporting rack
Roller link, is connected with grinding roller connecting shaft on grinding roller link, grinding roller connecting shaft lower end is connected with grinding roller, its design feature exists
In：In the vertical view orthographic projection view of the suspension strut structure, the axle center of the grinding roller connecting shaft and the axle center of main shaft are connected
Line segment to connect with the heart line segment, the intersection point of connect with the heart line segment and the axial line of the hinge shaft than grinding roller connecting shaft axle center from main shaft
Axle center closer to.
As the improvement of above-mentioned technical proposal, the line segment that connects with the heart is mutually perpendicular to the axial line.
The intersection point of the axial line of connect with the heart line segment and the hinge shaft than grinding roller connecting shaft axle center from main shaft axle center more
The near and described line segment that connects with the heart is mutually perpendicular to the axial line, and hinge shaft can be made to be entirely located in using the axle center of main shaft as the center of circle, with mill
The distance of the axle center of roller connecting shaft to the axial line of main shaft is inside the reference circle of radius.Hinge shaft is entirely located in above-mentioned reference circle
Portion, i.e. hinge shaft are located on the inside of the axle center of the grinding roller connecting shaft so that hinge shaft is closer to the centre of Raymond mill cylinder, so
The diameter of Raymond mill cylinder can be effectively reduced, so as to reduce system institute required airflow, reduces energy consumption.Moreover,
And the present invention is on the basis of existing technology, increase any part is not required to, hair is only achieved that by the change of hinge shaft position
Improving eyesight, therefore also have the advantages that simple in structure.
The second technical problem to be solved by the present invention is to produce the strong shake of tangential direction at work for above-mentioned grinding roller
The defects of service life that is dynamic and reducing equipment, there is provided a kind of suspension strut structure of raymond mill grinding roller, so that Raymond mill
When crushing the material of larger particles, tangential direction vibrations mitigate powder machine, increase the service life of equipment.
In order to solve the above technical problems, the present invention has done following improvement：By the axle center of the grinding roller connecting shaft and vertical
It is intersection point in the vertical line of axial line and the intersection point of the axial line of the hinge shaft, connects the axle center of the grinding roller connecting shaft and hang down
The line segment of foot is vertical line section, and the angle α between the vertical line section and the line segment that connects with the heart is acute angle, so that the hinge shaft is in its one end ratio
Skewed setting of its other end closer to the axle center of main shaft；The intersection point than grinding roller connecting shaft axle center from main shaft axle center
Closer to.
After improvement, the intersection point of the axial line of the intersection point and connect with the heart line segment and the hinge shaft is than grinding roller connecting shaft
Axle center from main shaft axle center closer to and the angle α between the vertical line section and the line segment that connects with the heart is acute angle, so sets the effect obtained
Fruit is：Hinge shaft have rotated the angle of a α with respect to the axle center of grinding roller connecting shaft, hinge shaft is more leaned on than its other end in its one end
The skewed setting in the axle center of nearly main shaft；Hinge shaft is predominantly located in using the axle center of main shaft as the center of circle, with the axle center of grinding roller connecting shaft
Distance to the axial line of main shaft is in the reference circle of radius.The skewed setting of hinge shaft can make counter-force suffered by grinding roller comminuting matter with
Its stress swaying direction is basically identical, equipment run when grinding roller vibrations will mitigate, so as to accordingly increase making for equipment
With the service life, the angular dimension of α can be adjusted according to material size size, and material size is bigger, and α angles are bigger.And hinge shaft is big
Part is positioned at the indexing using the axle center of main shaft as the center of circle, using the distance of the axial line in the axle center of grinding roller connecting shaft to main shaft as radius
In circle, the diameter of Raymond mill cylinder can be effectively reduced, the reduction of Raymond mill barrel diameter, can reduce system institute required airflow, i.e.,
Low-power fan air-supply can be used, so as to reduce energy consumption accordingly.
In summary the advantage of the invention is that：The diameter of Raymond mill cylinder can be effectively reduced, so as to reduce system institute
Required airflow, reduces energy consumption；Counter-force suffered by grinding roller comminuting matter and its stress swaying direction can be made basically identical, equipment fortune
The vibrations of grinding roller mitigate during row, so as to accordingly increase the service life of equipment.Moreover, and the present invention is in existing skill
On the basis of art, increase any part is not required to, goal of the invention is only achieved that by the change of hinge shaft position, therefore also there is knot
The advantages of structure is simple.
