Device and Method for Chemo-Physical Modification of Particles of a Suspension

Auflistung Beschreibung

The invention pertains to a device designed to disintegrate particles within a suspension using ultrasonic sound. It features a channel for the suspension with a designated particle-processing section, at least one pump to regulate the suspension’s flow velocity, and an ultrasonic sound source positioned to generate an ultrasonic field within the particle-processing section. By adjusting the flow velocity in relation to inertial forces like gravity or centrifugal force, particles can be arranged in a predefined spatial distribution within the channel.

Wichtigste Patentansprüche:

1. A device (1) for disintegrating particles (3) of a suspension with ultrasonic sound, the device (1) comprising:

– a channel (10) for a suspension, wherein the channel (10) comprises a particle-processing portion (12),

– at least one pump (20) configured and arranged to adjust a flow velocity of the suspension in the channel (10),

– at least one ultrasonic sound source (30), arranged such at the channel (10) that an ultrasonic field generated by the ultrasonic sound source (30) extends at least in the particle-processing portion (12) inside the channel (10),

wherein the device (1) is configured such that particles (3) of the suspension are arrangeable in a predefined spatial particle distribution in the particle-processing portion (12) of the channel (10) by adjusting the flow velocity of the suspension with respect to an inertial force (40) acting on the suspension,
wherein the inertial force (40) is gravity (42) or a centrifugal force (44).

2. Device (1) according to claim 1, wherein if the device (1) is configured to process the particles (3) by means of gravity (42) as the inertial force (40), the channel (10) comprises a straight section (14) that comprises the particle-processing portion (12), wherein the channel (10) is oriented such that the flow velocity of the suspension is oriented against gravity (42).

3. Device (1) according to claim 1, wherein if the device (1) is configured to process the particles (3) by means of a centrifugal force (44) as the inertial force (40), the channel (10) comprises a curved section (16) that is curved around a central axis (50) along the direction of gravity (42) and comprises the particle-processing portion (12).

4. Device (1) according to one of the claims 1 to 3, wherein the ultrasonic sound source (30) is arranged in the channel (10) such that the channel (10) encloses the ultrasonic sound source (30), enabling the suspension to pass the ultrasonic sound source (30).

5. Device (1) according to one of the preceding claims, wherein the device (1) comprises a settling portion (94), where settled particles (3) of the suspension are received.
