In recent years, new double-mass vibrating mill begins to occur, and is characterized in that mill tube is divided into mill tube and following mill tube two parts, and is middle with the flexible member connection, becomes respectively during work and goes up the vibration plastid and vibrate plastid down; Following mill tube is bearing on the basis by flexible member, and this flexible member also is the isolation mounting between vibromill and the basis.Though this class vibromill noise descends to some extent, but other shortcoming keeps substantially, and exciting device is arranged in down on the vibration plastid, and link by yielding coupling and common motor, making upper and lower plastid especially go up mass vibrating intensity decreases, problems such as refinement in grinding process, occur being difficult for, should not be used for the superfine grinding occasion.
Summary of the invention
The object of the present invention is to provide a kind of vibration isolation that can realize between vibromill and the basis, can guarantee or suitably improve the vibrating motor direct drive type double-mass vibrating grinding machine of the oscillation intensity that goes up plastid again.
Mill tube, last plastid, following plastid, vibrating motor, main vibration spring, shock-absorbing spring, base plate have been the present invention includes; Wherein above-mentioned mill tube is consolidated on the plastid; Above-mentioned going up relies on the guide pillar on main vibration spring and the upper and lower plastid to link between plastid and the following plastid; Above-mentioned plastid down is bearing on the base plate by shock-absorbing spring; Above-mentioned vibrating motor upside-down mounting under the supporting plate of last plastid, be power source be again exciting source.During work, upper and lower plastid is with different amplitudes and acceleration vibration.Obviously, the amplitude and the acceleration of last plastid are bigger, can improve the impact grinding ability of the interior medium of mill tube to material; The amplitude and the acceleration of following plastid are less, can reduce to pass to the dynamic loading on basis more greatly by isolation spring.
Vibrating motor is simple in structure, can change the exciting force of system and the size of oscillation intensity by adjusting outer eccentric weight and the inboard fixedly relative angle of eccentric weight.Main vibrating system adopts cylindrically coiled spring, with the work requirements of adaptive system Near resonance oscillating, reaches the purpose of system stability work, efficient energy-saving.Vibration insulating system adopts the shock-absorbing spring of ring-shaped rubber spring as vibration insulating system, and elastic modelling quantity is little, can obtain bigger strain, the nonlinear characteristic of easily realizing ideal; System has high internal resistance, and is good to the absorption and the vibration isolating effect of sudden applied load.The present invention can obviously improve mill efficiency as corase grind; As fine grinding, can significantly reduce noise, power consumption, in the service life of the parts maintenance frequencys such as minimizing bearing, prolongation consumable accessory, realize ultra-fine grinding or reach ultramicro grinding.

Number in the figure title: 1. 5. times plastids of plastid 3. vibrating motors, 4. main vibration springs, 6. shock-absorbing springs, 7. base plates on the cylindrical shell 2..
The specific embodiment
As shown in Figure 1, this vibrating mill is made up of last plastid 2, following plastid 5, vibrating motor 3, mill tube 4, base plate 7, main vibration spring 4, shock-absorbing spring 6.Mill Jie packing factor of vibrating mill is than higher.Mill is situated between and is the spheroid of abrasion-proof steel ball, rod iron, steel section, oxidation ball, porcelain ball or other material, and the diameter that mill is situated between is generally 1-10mm, and it is also corresponding higher that it grinds efficient.The vibration frequency of vibrating mill is at 1000-1500 time/min, and its amplitude is 3-30mm.Select the size of vibration frequency and vibration amplitude, all the crushing effect that mill is situated between has very big influence.
The vibrating motor 3 of the present invention's employing produces exciting force by its eccentric block rotation as seen in Figure 1, drives system works, and abrasive material is ground.Vibrating motor is simple in structure, can adjust outer eccentric weight and the inboard fixedly relative angle of eccentric weight, so just can change the size of exciting force and oscillation intensity.
As shown in the figure, the centrifugal force that vibrating motor is produced when rotating by eccentric block drives goes up the plastid motion, power directly drives mill tube, different medium of diameter and powder are housed in the mill tube, mill tube produces strong circular vibration like this, thereby mills such as steel ball in the mill tube are situated between material is produced collision, impacts and rub with the hands mill, reach material is pulverized purpose with fine grinding.By the offset of regulating eccentric block, the grating selection that changes mill Jie etc., can reach the purpose of control product granularity and productivity ratio.
During vibrating mill work running, high-frequency percussion that mill is situated between and strong abrasive action are levigate with material, and this process causes particle to crack mainly due to grinding the repeated stock that is situated between with abrasive material in the mill body.When solid deformed, new surface was that the basis grows up gradually with these crackles just, after the unloading, under the effect of molecular force, they are " healing " again, and when just underwent mutation in the place of defective maximum in the weakest indivedual places, solid will produce the destruction of macroscopic view.And mill is situated between to the percussion of abrasive material high frequency in the vibromill, making these microfissues have little time " healing " just is subjected to continuously impacting, rapid expansion microscopic checks, the continuous expansion of crackle is so that pulverize, and it is effective therefore vibrating, collide, impact the fine grinding of carrying out solid material with this.
Know by the engineering site situation, because the influence of maximum load at random, if do not take suitable vibration isolation measure, very big dynamic loading can be passed to the basis, make ground and building produce harmful vibration, not only produce the noise pollution environment, under the serious situation, can make machine breakdown and stop production, and long-continued operation, not only this machine life-span shortens greatly, also can exert an influence to peripheral equipment and building.
Mirror be designed to the double-mass vibrating grinding machine in this present invention, the main mode of shaking is not only arranged, and vibration isolation mode is arranged.
