Abstract

The invention concerns a method for activating a sieve frame with ultrasounds. The invention aims at developing a method for activating a sieve frame with ultrasounds, which enables the use of sieving devices with more compact structure than current known ones. Said aim is achieved by the fact that the sieve frame is activated as longitudinal oscillator. The sieve frame (1) is activated in particular via a coupling element (2) which offsets the oscillating system (4) activation axis (5) in the sieve frame (1) plane transmitting the oscillations.

Description

Activate the method for a screen frame (unit) with ultrasonic wave
The present invention relates to activate a method of a screen frame (unit) with ultrasonic wave, what just preamble as claimed in claim 1 was limiting.
It is known using ultrasonic wave to screen different article.The oscillating movement that is produced by ultrasonic wave is delivered to the surface of sieve and to the treating capacity of sieve and the screened useful effect of material production.The vibration that is delivered to screened material reduces surface tension and coagulability, thereby has greatly prevented the obstruction of screen cloth.
Use hyperacoustic known screening plant and screening technique to consist essentially of a screen frame (unit), a sieve surface is installed, and a ultrasound source is coupled on the screen frame (unit) through a ultrasonic transducer on this screen frame (unit).Converter is converted to the mechanical bend vibration with the high-frequency electrical vibration.
In WO94/27748, described that a ultrasonic transducer that adopts a sieve surface and be used for this sieve surface screens, sorting, sieved, filter or sort one of material and install and a method, wherein sieve the surface and be arranged in the screen frame (unit), and ultrasonic transducer can impel the sieve surface vibration.
Be complementary near a resonator on sieve surface and the resonance (frequency) of ultrasonic transducer, and can be impelled in the bending direction vibration by the latter, this resonator is used for ultrasonic transducer.The extensional vibration that is produced by sound transducer is converted into the flexural vibrations of same frequency in the bar of resonator, wherein the bar of resonator is tangential on vertical setting of vibration.
One shortcoming of all known embodiments is large scales of bringing owing to its operation principle, makes screening plant can not have enough compact structure shapes, and wherein this operation principle must activate a flexural resonance device and vibrates.
A purpose of the present invention is to set up a method that activates screen frame (unit) by ultrasonic wave, guarantees the structure than a known compacter screening plant thus.
This purpose is finished by the distinguishing characteristics of claim 1.Favourable scheme of the present invention provides in the dependent claims.
Employing activates a screen frame (unit) as the ultrasonic wave of longitudinal vibrator can guarantee that the structure of screen frame (unit) is more flat, thereby beguine is compacter according to the screening plant that flexural resonance device principle activates.
Especially, by being installed in the element place that activates by vibration (for example screen frame (unit)), can obtain a compact structure, because vibrational system is arranged under the screen frame (unit) with vibrational system being had a lateral shift.In addition,, can adopt annular (even oval) structure, especially when the activation axis of vibrational system is moved in the plane of screen frame (unit) transmitting vibrations by a linkage element for screen frame (unit).
Further describe the present invention with an annular frames below.In unique accompanying drawing, show a schematic diagram of the annular frames that has a ultrasound source.
According to this schematic diagram, form a circular screen frame (unit) 1 by even number λ/2 elements, form a λ/2 elements by a linkage element 2.
Linkage element 2 comprises 2 λ/2 longitudinal vibrators 3, and these vibrators are connected with each other in its peak swing direction.
Produce a hyperacoustic vibrational system 4 (ultrasonic transducer) is installed in linkage element 2 as a λ/2 longitudinal vibrators bottom λ/2 longitudinal vibrators, 3 places.
The high frequency machinery extensional vibration that is produced by ultrasonic transducer 4 passes to screen frame (unit) 1 through linkage element 2, is shown in the fabric (not shown) that transmits and pass to equably sieve on the whole circumference as the II among the figure.
In the situation on large-scale sieve surface, according to the geometry on sieve surface, it may be suitable under the sieve surface several circles, ellipse or rod screen frame (unit) 1 being set, to guarantee an effective screening function.
I in the accompanying drawing is illustrated in the vibration processes in converter 4 and the linkage element 3.II is represented the vibration processes in the screen frame (unit) 1, and amplitude a marks and draws with respect to vibrational coordinate x in I and II.At coordinate x oAll there is centre of oscillation point at the place in each situation.
Because the extensional vibration of system 4, impel to be installed in the sieve of one on the screen frame (unit) 1 and laterally to move in a mode that very is similar to the motion of in the manual screening process, sieving.Compare with the known screens screening device of prior art, the actuating on sieve surface has been offset 90 °.
The invention is not restricted to embodiment described herein, but, by combination, can realize further example and do not depart from the scope of the present invention distinguishing characteristics.Therefore, also can be advantageously in conjunction with the flexural vibrations device motion of known type in longitudinal vibrator motion of the present invention and the screen frame (unit).
