Description
Technical field
The present invention relates to vertical roll grinder, more particularly, to the grinding roller pressure structure suitable for vertical roll grinder.
Background technology
Vertical roll grinder is mainly used in milling field, have equipment is simple, rational in infrastructure, manufacturing cost is low, yield is high,
It is with small vibration during operation, power consumption it is low the features such as, suitable for materials such as grinding slag, ore, coals, also available for superfine grinding.
In the general structure of vertical roll grinder, transmission device（Including motor, reductor etc.）Form, arrangement it is all basic
Similar, comparative maturity, distinctive points are concentrated mainly on the difference of pressuring method.At present, divide from pressuring method, vertical roll grinder
Pressure mode mainly has following several：
First, as shown in Fig. 2 the vertical roll grinder is fixedly connected by transmission arm 2.1, rocking arm 2.2 with Burnisher apparatus 2.3, installation
Pressurized cylinder 2.4 in grinding machine bottom applies 2.1 plus pulling force to transmission arm, and by grinding roller bearing 2.5, rocking arm 2.2 and with rocking arm 2.2
The Burnisher apparatus 2.3 being fixedly connected, pulling force is converted into the grinding pressure to material on mill 2.6, so as to realize grinding purpose, mill
Roller arrangement 2.3 does pendular movement up and down around grinding roller bearing 2.5.The pressuring method, it is by the pressurization oil installed in grinding machine bottom
Cylinder 2.4, it is transferred to grinding roller by transmission arm 2.1, grinding roller bearing 2.5, rocking arm 2.2 power that will be milled and puts on material.From adding
Power position between stress material will pass through several parts carry out power transmission；By structure is limited, each stressed member shape ten
Point complexity, causes each part stress deformation to produce vibration, and causing to pressurize, efficiency is very low, and mill efficiency is undesirable.Meanwhile transmission arm
2.1st, rocking arm 2.2, the design of lower body and grinding machine support 2.7, manufacturing cost are higher.
2nd, as shown in figure 3, all grinding roller 3.1 of the vertical roll grinder is mounted thereon on the increased pressure frame 3.2 at end, add
Several parts of press box frame 3.2 are overall by being fixedly connected as a rigidity；Several pressurization oil cylinders 3.3 are by pull bar to pressure frame
Frame 3.2 applies pulling force, and power is transferred into grinding roller 3.1 by increased pressure frame 3.2, realizes and material on mill is rolled, so as to
Realize grinding purpose；Grinding roller 3.1 does upper and lower translation motion with increased pressure frame 3.2 during work.Because structure limits, increased pressure frame
3.2 circumferencial direction rotation control it is more difficult；Meanwhile the axial posture of its grinding roller 3.1 also bad control.Increased pressure frame
3.2 be stress part the most complicated, and the control to it is most important, and the position of increased pressure frame 3.2 is controlled in the design, main
If realized by housing 3.4, that is to say, that the out-of-balance force such as circumferential, lateral suffered by increased pressure frame 3.2 will transmit
Onto housing 3.4；And housing 3.4 26S Proteasome Structure and Function of itself determines that its strength and stiffness is not suitable for bearing the power of complexity, and
And due to material became uneven on mill, along with the influence of feeding manner and direction of rotation, material thickness inequality degree sometimes
Very serious, so several grinding rollers 3.1 are depressed and lifted simultaneously, will be produced big vibration, are caused grinding machine fluctuation of service, vibration tendency
Become apparent, this allows for overall operation and very big destabilizing factor be present.Because the needs of grinding, wheel the form of the foetus grinding roller 3.1 are normal
Often it is designed to be not orthogonal to mill card, and grinding roller 3.1 and increased pressure frame 3.2 are vertical depressions, its direction run and roll body
Not in the same direction, it so also have impact on mill efficiency.Meanwhile the oil cylinder 3.3 that pressurizes is connected to increased pressure frame by a long draw 3.5
On 3.2, because the length of pull bar 3.5 is very long, rigidity is low, has very big elastic deformation under the pulling force of pressurization oil cylinder 3.3 so that its
Being pressurized to the reaction time of grinding roller 3.1 can increase, so as to influence grinding effect.
3rd, as shown in figure 4, the vertical roll grinder pressurizes, oil cylinder 4.1 is directly connected in the outer of grinding roller 4.3 by pull bar 4.2
On the Rocker arm 4 .4 of side, and pulling force is applied to it, power is transferred to by grinding roller 4.3 by Rocker arm 4 .4, realized to material on mill 4.5
Roll, so as to realize grinding purpose.Grinding roller 4.3 does pendular movement up and down around grinding roller bearing 4.6 during work.The pressurization of the grinding machine
Point upright projection is located at the inner side of grinding roller split 4.7, and has a segment distance, is unfavorable for carrying out grinding pressurization.By force analysis
Understand, its stress of grinding roller bearing 4.6 is big, complicated；Pressurization oil cylinder 4.1 is connected to Rocker arm 4 .4 by a long draw 4.2
On, because pull bar 4.2 is very long, rigidity is greatly reduced, pressure-responsive is slow；The oil cylinder 4.1 that pressurizes simultaneously is located at grinding machine bottom, installs
In the inside of grinding machine support 4.8, this make it that the short transverse size of grinding machine support 4.8 is very big, adds the weight of grinding machine support 4.8
Amount, also reduce the overall rigidity of equipment.
The content of the invention
Present invention aims at provide a kind of grinding roller pressure structure suitable for vertical roll grinder.
To achieve the above object, the present invention takes following technical proposals：
