Description
Technical field
The present invention relates to vibrosieve, particularly relate to a kind of for judge the mark of shaker vibration mode, vibrosieve and
Method.
Background technology
Single vibration source produces single vibration mode, generates single sine wave, and complex vibration source produces complex vibration mode,
Generate coupling sine wave.Therefore, being in the nature of vibration, the polynary secondary coupling of vibration wave.
The vibrosieve that existing market uses in a large number is " triple unit vibration screen ", as the term suggests, three-D is: upper and lower, left
Right, front and back；Being vibrated by three-D acts on screen cloth jointly, makes material produce different movement locus on screen cloth, then executes
With ultrasound wave, reach the effect that material sieves.
Being limited by aspects such as space, powder, funds, the workload of vibrosieve is big, even it is frequently necessary to bear not
Having broken operating mode, material size is increasing so that the sieve plate and the sieve plate screen frame that are originally easy for damage can't bear the heavy load, vibration
The frequency that sieve spare part damages is greatly improved, and has a strong impact on normal scheduling of production.
For preventing the damage of vibrosieve spare part, need the mode of vibrations such as the trend of the material to vibrosieve, amplitude, vibration angle
It is adjusted and controls.And the material vibrating mode of vibrosieve regulates, it always is dependence experience, such as after using glove to place
Carry out the mode of vibration of vibrosieve is judged, or upper cover is opened, observe the mode of vibration to vibrosieve.But on,
The mode of vibration of vibrosieve cannot be quantified by micro-judgment after all that state, it is impossible to tackles the problem at its root.
Summary of the invention
The one of the present invention aims to overcome that the deficiency of prior art, it is provided that a kind of for judging shaker vibration mode
Mark, to carry out part quantization or all to quantify to the mode of vibration of vibrosieve.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of mark for judging shaker vibration mode, it is characterised in that: it includes the circle and at least of at least one
Article one, the ray outwards dissipated centered by a point.
After opening vibrosieve, point of observation, circle, ray, to judge the overall operation situation of vibration.Solve the cracking of vibrosieve
Problem, first has to solve amplitude controlling problem, and beating of the circle of different-diameter can form vision ghost, when ghost is tangent, amplitude
With equal diameters, therefore, by arranging the circle of different-diameter, in the case of fixed amplitude, ghost can be found the most tangent
Circle, this circular diameter is Oscillation Amplitude, as shown in Figure 3.On the other hand, the difference of vibration wave coupled modes creates difference
The vibration of angle, therefore, uses outside diverging ray detection vibration θ angle centered by a point, and vibration θ angle is that horizontal line is to shaking
The minimum angles (0 °～90 °) of the ray can being clearly apparent during Dong.
It is to say, by above-mentioned mark, the three-dimensional coupled motions of vibrosieve can be decomposed, with quantitatively or semi-quantitatively
Mode shows.
In screen cloth vibration processes, vibration θ angle and rotation directionDetermine material trend on screen cloth, when vibration θ angle with
Rotation directionOne is clockwise one for time counterclockwise, and material draws close to center, and lower floor's screen frame material is by outwards sieving after mutually extruding
Point, screen cloth is prone to damaged in center；And when vibration θ angle and rotation directionWhen being all clockwise or be all counterclockwise, material to
Surrounding spreads, and material relies on centrifugal force to be slowly diffused to surrounding by center, is sieved by screen cloth simultaneously, and this is preferable
Screening state, be extended the service life of screen cloth.
In the embodiment recommended, described ray outwards dissipates along the circumference with described point as the center of circle.So, can use
The three-dimensional motion of point describes oscillation trajectory.
In the embodiment recommended, the angle between adjacent two described rays is more than 3 °.Under such angle, ray
Distribution will not too closely, can clearly and relatively accurately describe vibration θ angle.
In the embodiment recommended, when the quantity of described circle is more than one, each described circle is the circle of different-diameter, described
The circle of different-diameter is arranged on a straight line from small to large or from big to small.
In the embodiment recommended, when the quantity of described circle is more than one, each described circle is the circle of different-diameter, described
The circle best-fit of different-diameter is on a straight line.
