Description

High-amplitude vibrating mill

The utility model relates to the materials crusher device of industries such as can be used for metallurgy, building, coal, chemical industry, light industry.

Vibro grinding is the heat subject of current domestic and international disintegrating apparatus development, because vibro grinding can reach the purpose of " multi-hit few mill ", has the production efficiency height, energy-conservation, low consumption, advantages of simple structure and simple.At present domestic vibrating mill is of a great variety, but common regular defect is many, has two sediment outflow inequalities as double-cylinder type, the cylindrical shell concentrated wear is very fast, and bolt ruptures easily, and support spring damages easily, defect such as easy torsional oscillation bring operating reliability poor to equipment, and this is that user's worries greatly.

The purpose of this utility model is exactly for overcoming the shortcoming of above-mentioned vibrating mill, bring into play the advantage of vibrating mill better, in the reliability of the effect of power and distribution, Structure ﹠ Intensity, safe handling, the aspects such as maintainability of part service life and equipment are improved in addition.

Solution of the present utility model is: the principle of utilizing mechanical oscillation, make that mass of vibration obtains that height shakes frequently, high amplitude and high oscillation intensity, make medium form centrifugal force field, strong impelling, impact, extruding, mill stripping powder ore, eccentric block and cylindrical shell are housed on frame, and frame is contained on the air spring, and eccentric block is by the output shaft transmission on the motor, motor and air spring all are contained on the base, it is characterized in that eccentric block center of rotation axis skew frame center line; Four supporting-points of air spring on base adopt the setting of center, diagonal angle concurrent force system; Frame adopts and fastens cylindrical shell to centroclinal open band rim of the mouth; Fitting surface at air spring is coated with fluid sealant, and adopts high-pressure valve to chew; Feed pipe and cylindrical shell are tangent; Sand removing hole is at an end of cylindrical shell, and its detailed content is described below referring to accompanying drawing:

Referring to Fig. 1, eccentric block (4) and cylindrical shell (5) are housed on frame (3), eccentric block (4) is by output shaft (2) transmission on the motor (1), motor (1) and air spring (6) all are contained on the base (7), the center line of the transmission central axis skew frame (3) of eccentric block of the present utility model (4), because of existing two sediment outflow inequalities of dual-drum vibration mill machine, output differs and can reach 20%-30%, the reason that above-mentioned phenomenon occurs is because the pivot of eccentric block is coaxial with the frame central line, one side exciting force of eccentric block hammering is big, the amplitude height, therefore the sediment outflow inequality appears, bring unbalance stress also for simultaneously the both sides air spring, design of the present utility model has improved the force-bearing situation of both sides air springs and has made the sediment outflow equilibrium, four supporting-points of air spring (6) on base (7) adopt the setting of center, diagonal angle concurrent force system, because of torsional oscillation appears in vibrating mill is very harmful, the one, influence equipment component service life, the 2nd, influence grinding efficiency, supporting-point of the present utility model adopts center, diagonal angle concurrent force system, except that avoiding producing the new power system, to around the timely balance of any point variation of force, to improving the stability of vibrating mill, it is important to prevent that torsional oscillation from having play a part, frame of the present utility model (3) adopts and fastens cylindrical shell (5) to centroclinal open band rim of the mouth, avoiding vertical straight line opening cylindrical shell card gravitate to produce influence tired and that bolt is sheared becomes flexible, fracture, the gravity of whole cylindrical shell is all acted on the frame, the reliability that raising equipment runs well.The utility model is coated with fluid sealant at the fitting surface of air spring (6), and adopt high-pressure valve to chew, strengthen the sealing of air spring (6), eliminate leaking source, improved the functional reliability of air spring, reduced because the equipment breakdown that the damage of air spring causes.Feed pipe of the present utility model (9) is tangent with cylindrical shell (5), sand removing hole (10) is at an end of cylindrical shell (5), be long cylindrical shell service life of existing grinding machine, but the cylindrical shell concentrated wear is very fast relatively, concentrated wear as feed end is because feed pipe radially is connected with the cylindrical shell employing, it is good opposite with the cylindrical shell direction of rotation that the ore feedstock direction is in harmony, it is that contract is gone into that ore enters cylindrical shell, cylindrical shell goes into the angle for the certain contract of ore, ore must be left a passage by the natural law, this just makes the cylindrical shell concentrated wear very fast, the utility model adopts tangential admission, instead do not increased cylindrical shell pan feeding area, and had the contract of ore to go into clear passage, the concentrated wear speed of charging aperture just greatly reduces.The product of the sediment outflow end of existing grinding machine has formed the district that falls through in this zone when discharging, medium and cylindrical shell directly bump, friction, this just adds the wearing and tearing of having brushed this regional inner barrel, the utility model is arranged in the end of cylindrical shell (5) with sand removing hole (10), so both shortened district's concentrated wear scope of falling through, increased having of cylindrical shell again and used length, the life-span of cylindrical shell also can improve.

The high-amplitude vibrating mill that the utility model provides is because reasonable structural design, the stress equalization and the stability of complete machine are improved, the equipment operation performance improves greatly, has improved the service life of locking, anti-shearing, fatigue resistance and other part of equipment simultaneously.

Accompanying drawing has been represented embodiment of the present utility model.
