Description

Vibrator position adjustable plane revdution oscillating screen

Technical field

The utility model relates to a kind of for the adjustable plane revdution oscillating screen in granule materials grading technology vibrator position.

Technical background

Plane revdution oscillating screen is the vibrating machine of being done the complex track motion by inertia vibration generator exciting, sieve nest in horizontal plane, and it is widely used in the industries such as oil and foodstuffs, chemical industry, medicine, is used for finishing the graded operation of granule materials.Its main feature be sieve nest longitudinally from feed end to discharge end, vibration mode gradually becomes reciprocating linear vibration by the elliptical orbit rotary vibration, the long axis sieve nest of feed end elliptical orbit is horizontal, and is vertical near the long axis sieve nest of discharge end elliptical orbit.Accompanying drawing 1 is sieve nest extensional vibration trail change schematic diagram.The elliptical orbit rotary vibration of sieve nest feed end helps laterally evenly to scatter and automatic classification along sieve nest fast into the machine material, the path length that contacts of material and sieve nest in vibration period simultaneously, but vertically advance little, in time the sieving of the material particles that is conducive to sieve; The particle that should sieve on a small quantity that contains in the material when the discharge end embarrass the sieve particle substantially, near the reciprocating linear vibration of sieve nest discharge end or near the elliptical orbit rotary vibration of reciprocating linear vibration, is conducive to sieving vertical propelling with material of difficult sieve particle.Compare with the rotary flat sieve of single round track rotary vibration, cleaning effect is good, output is high.

Accompanying drawing 2 is existing plane revdution oscillating screen structural representation.Sieve nest is hung on frame by the elastic boom of four groups of verticals, and inertia vibration generator is installed below the sieve nest near feed end, and sieve nest discharge end below is equipped with stopping means; Inertia vibration generator is driven by the band transmission by the motor that is installed on the sieve nest, under the excitation of inertia vibration generator inertia force and under the constraint of stopping means, elastic boom, sieve nest is done the different elliptical orbit motion of long axis direction from feed end to discharge end in horizontal plane, and discharge end is done the center of circle and the constant arc track double vibrations of radius.Accompanying drawing 3 is existing plane revdution oscillating screen sieve nest extensional vibration trail change and stopping means schematic diagram.

Existing plane revdution oscillating screen Main Problems in application is as follows:

1. the installation site of inertia vibration generator is fixed at sieve nest, can not regulate, and sieve nest can only by a kind of complex track vibration of combining form, can not satisfy various materials and sieving technology to the requirement of different composite track vibration.

2. because the sieve nest discharge end is done the arc track double vibrations, the material on the discharge end sieve nest deviation phenomenon occurs along the sieve nest width under the effect of centrifugal force.

3. owing to the constraint of stopping means to the sieve nest motion, part sieve nest inertia force passes to frame by stopping means, has increased the dynamic loading that frame is subject to, and frame vibration is larger.

Summary of the invention

The purpose of this utility model is: overcome the prior art deficiency, provide a kind of technical performance higher and can satisfy the vibrator position adjustable plane revdution oscillating screen of multiple sieving technology requirement.

The utility model realizes that the employed technical scheme of above-mentioned purpose is:

Sieve nest is hung on frame by the elastic boom of four groups of verticals; Inertia vibration generator is driven by the band transmission by motor, and motor and inertia vibration generator are installed on the adjusting device, and this adjusting device is installed on the sieve nest; Can when vibratory sieve is static, vertically regulate the position of inertia vibration generator along sieve nest by adjusting device, fixing after adjusting is finished.

The utlity model has following beneficial effect:

1. the position of inertia vibration generator is adjustable, and sieve nest can obtain multiple multi-form complex track, can satisfy the requirement of multiple different material and sieving technology.For example, when the higher output of sieving technology important requirement, by regulating the position of inertia vibration generator, sieve nest can obtain the oscillation trajectory of form shown in the accompanying drawing 1, and the linear reciprocating motion of sieve nest discharge end helps to accelerate discharge velocity, improves output; When the higher cleaning effect of sieving technology important requirement, by regulating the position of inertia vibration generator, can obtain the oscillation trajectory of form shown in the accompanying drawing 4, this plane rotation vibration that is elliptical orbit from the sieve nest feed end to discharge end, prolong the screen route, thereby can obtain preferably cleaning effect.

2. the sieve nest discharge end does not have stopping means, so the sieve nest discharge end can not done the arc track double vibrations, has eliminated the material deviation phenomenon; Simultaneously, also reduce to pass to the sieve nest inertia force of frame, reduced the vibration of frame.
