Description
Horizontal variable force vibrating mill is a kind of milling equipment that is applicable to material super-fine processing such as light industry, chemical industry and nonmetallic mineral.
Horizontal vibromill drops into industry by design such as English, moral, the Soviet Union at first and uses, and year historical surplus having 60 approximately so far, China introduces the horizontal vibromill of Soviet Union's formula single cylinder the fifties, develop the horizontal vibromill SN of homemade three cylindrical shells series the seventies.
Existing horizontal vibromill all is by yielding coupling 2 by motor 1, drive line shaft 12 rotations, make the eccentric block group that is fastened with line shaft 12 produce eccentricity excitation power, because of cylindrical shell 6 is bearing on the stage clip 5, and link to each other with line shaft 12 by connecting gusset, therefore cylindrical shell 6 produces plane motion under eccentricity excitation power.The motion of cylindrical shell, (steel ball) is in vibrational state so that dress mill within it is situated between, and constantly impacts material, makes the material refinement.Because of the horizontal grinding machine of tradition, what its line shaft 12 was installed is two groups of eccentric block groups that equate, two constant amplitudes have been produced, the eccentric force of homophase, be exciting force, cylindrical shell only forms garden, plane Zhou Yundong, and the oscillation intensity that mill is situated between in (being two dimensional motion) thereby the cylindrical shell is low, Flow of Goods and Materials is slow, the energy consumption height of unit product.For head it off, the U.S. has designed vertical vibration grinder, and cylindrical shell is realized three-dimensional motion, promptly except that the rotation of horizontal plane, has also increased the play up and down of cylindrical shell, to strengthen the vibration that mill is situated between, strengthens mill and is situated between to the impact of material.But this equipment price costliness, as 700 liters of vertical vibration grinders that the nonmetal research institute in Xianyang introduces, price is up to 170,000 dollars.And its mill Jie vibration severity still has deficiency.
The purpose of this utility model be for overcome traditional horizontal vibrating mill etc. the power exciting, cylindrical shell is only done two dimensional motion, mill Jie oscillation intensity is low, Flow of Goods and Materials is shortcoming slowly, designed a kind of simple in structurely, cost is low, and has good anti-turning over and the variable force vibrating mill of anti-linear resonance.
Be described in detail the utility model below in conjunction with accompanying drawing.

This Horizontal inotropic vibromill, as shown in Figure 1, by motor 1, the yielding coupling 2 that links to each other with line shaft 12 with motor shaft; Two bearing blocks 15 supportings is arranged, link to each other with shaft coupling 2, and the line shaft 12 that is fastened with two eccentric block groups; One end is fixed on the support 13, and the other end is fixed on the helical compression spring 5 on the connection gusset of cylindrical shell 6 Joints; The feed inlet and outlet (8,10) that is opened on the cylindrical shell is installed in interior filter mill Jie of cylindrical shell, and two groups of eccentric block groups and anti-turning-up devices form. Be characterized in that two groups of two eccentric block groups (4,9) are adjustable by angle between two groups of adjacent eccentric blocks, and by bolt and line shaft 12 Joints. Its anti-turning-up devices, by bolt respectively with connecting plate and frame 13 Joints in cylindrical shell 6 stage casings.
As shown in Figure 2, the left and right sides eccentric block 16 and 17 of pre-eccentric piece group 9 is tightened up mutually by bolt and line shaft 12 respectively, and the angle α between 16 and 17 can regulate as required, during the position, produces when then left eccentric block 16 rotates with axle 12 as shown
Exciting force, right eccentric block 17 produces
Exciting force, pre-eccentric piece group produces total off-centre and then is with joint efforts
And F1The ∑ of making a concerted effort

With
The angle of axle is phase, and the size of therefore regulating the angle α between two eccentric blocks then can change and close the eccentric force ∑
Amplitude and phase, the angle after in like manner regulating between adjacent two eccentric blocks of eccentric block group can change equally and close the eccentric force ∑With φ2Value, so cylindrical shell is at two eccentric force ∑s that amplitude is different from phase place as shown in Figure 3
And ∑
Effect is lower, garden Zhou Yundong not only occurs, and can produce the rotation around self barycenter, and (namely two to rotating) realized the four-dimensional movement of cylindrical shell. Broken through traditional horizontal grinding mill barrel and only made two dimensional motion, be i.e. the situation of circular motion. Because of the horizontal grinding machine of tradition, adjacent eccentric block 16 and 17 angle α equal zero, thereby ∑
And ∑Amplitude equate and phase1With φ2Homophase, phase difference1－φ
2Equal zero, under this two constant amplitude homophase exciting forces effect, cylindrical shell is only made two dimensional motion, and grinding machine of the present utility model is under the exciting force effect different from phase place of two amplitudes, cylindrical shell is in the four-dimensional movement state, mill Jie's (steel ball) who is contained in the cylindrical shell oscillation intensity is increased greatly, and the flowing velocity of material improves. Known to measured data in the experiment, under same fineness, output doubles many.
For fear of tumbling of resonance impact under this vibrational state and cylindrical shell, this machine is at the centroid position in the stage casing of cylindrical shell, be provided with anti-turning-up devices 7, its planform as shown in Figure 4, two sections non-linear wirerope springs 18 are arranged, and helical form flexible member and two groups of dops of only turning to axial ellipse garden shape are symmetrically formed.Every group of dop all has two fixed heads (19,20) compositions that have screw up and down.Last bottom plate is along the bus symmetry clamping of flexible member.And every group of dop is fastened with the connecting plate and the support 13 in cylindrical shell 6 stage casings respectively by bolt.The ellipse garden degree of the flexible member of institute's coiling can design by required rigidity requirement, owing to be nonlinear stiffness, then effectively avoided linear resonance and has tumbled phenomenon simultaneously.
The utility model is simple in structure, and cost is low, can improve mill efficiency greatly simultaneously.Be the data of the grinding experiment of an actual measurement on 30 liters of three cylindrical shells experiment mill below:
