Description

Technical Field

[0001] The utility model belongs to the technical field of ultrasonic pulverization, and in particular relates to an ultrasonic homogenizing component. Background Art

[0002] Ultrasonic homogenizer is a device that uses high-frequency sound waves to disperse, emulsify and homogenize mixed samples. Its working principle is that under the high-frequency vibration of the ultrasonic transducer, ultrasonic waves act on the mixed liquid, forming lateral and longitudinal fluctuations, and forming positive and negative alternating fluctuations including high-pressure and low-pressure areas inside the liquid. During the entire working process, compressible and volumetric tiny bubbles will be generated. Since the bubbles will explode rapidly in the high-pressure area, small bubbles with high temperature and high pressure difference will explode around the bubbles, forming multiple tiny cavities to collapse, and a large amount of energy will be released into the surrounding liquid, so that the surrounding liquid will generate a large amount of shear force and vibration force, realizing the dispersion, emulsification and homogenization of the sample.

[0003] Existing homogenizing equipment places the homogenizing tool head into a liquid container through a fixed transducer or amplitude modulator, and disperses, emulsifies and homogenizes the sample through the high-frequency vibration of the homogenizing tool head and acts on the mixed liquid. The homogenizing tool head is immersed in the liquid, which requires the ultrasonic system to provide greater power to ensure the vibration effect, and the working efficiency is low.

[0025] In order to more clearly illustrate the embodiments of the present application, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0026] In the description of the embodiments of the present application, the terms "upper", "lower", "front", "rear", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the application. In addition, the terms "first", "second", etc. are only used to distinguish in the description and have no special meaning.

[0027] According to some embodiments of the present application, Figures 1 to 5 As shown, an ultrasonic homogenizing component is provided, including a transducer 1, an amplitude modulator 2 and a tool head 3, wherein the transducer 1 is connected to the amplitude modulator 2, and the amplitude modulator 2 is connected to the tool head 3; the tool head 3 includes a connecting portion 31, a transition portion 32 and a dispersion portion 33 arranged in sequence along the axial direction, the connecting portion 31 is provided with a liquid inlet channel 311, the dispersion portion 33 is provided with a liquid outlet channel 331, the connecting portion 31 and the transition portion 32 are provided with a transmission channel 321, the liquid inlet channel 311, the transmission channel 321 and the liquid outlet channel 331 are sequentially connected and used to fill the mixed liquid, and disperse and homogenize the mixed liquid in the liquid outlet channel through ultrasonic vibration.

[0028] Furthermore, the transducer 1 is connected to the amplitude modulator 2 via a connecting bolt 11, and the amplitude modulator 2 is connected to the connecting part 31 via a connecting bolt 21. The connecting part 31, the transition part 32 and the dispersion part 33 are integrally formed and connected, and the diameter of the transition part 32 is smaller than that of the connecting part 31 to improve the ultrasonic vibration performance.

[0029] In some embodiments of the present application, a plurality of liquid outlet channels 331 are provided inside the dispersion part 33, and the plurality of liquid outlet channels 331 are respectively connected to the transmission channel 321, and the liquid outlet channels 331 are connected to the joint 4, and the inner diameter of the liquid outlet channels 331 is smaller than the inner diameter of the transmission channel 321. By setting the inner diameter of the liquid outlet channel smaller than the inner diameter of the transmission channel, not only can the large particle mixture flow out in the form of a smaller particle mixture after dispersion and homogenization, but also the large particle mixture can be vibrated and dispersed at the connection between the transmission channel and the liquid outlet channel, so as to further improve the dispersion and homogenization effect.

[0030] In some specific embodiments, Figures 1 to 3 As shown, a plurality of liquid outlet channels 331 are dispersedly arranged in a trumpet shape. One end of each liquid outlet channel 331 is commonly connected to the transmission channel 321, and the other end is arranged in a trumpet-shaped structure diverging outwards.

[0031] Furthermore, the angle between the liquid outlet channel 331 and the transmission channel 321 is set to 30-60°, preferably 45°, and can be specifically set according to actual needs and is not limited to the above angle.

[0032] In other specific embodiments, Figure 4 As shown, several liquid outlet channels 331 are arranged perpendicularly to the transmission channel 321 , one end of the several liquid outlet channels 331 is commonly connected to the transmission channel 321 and arranged along the circumference thereof, and the other end is arranged perpendicularly away from the transmission channel 321 .

[0033] In some embodiments of the present application, Figure 5 As shown, the liquid inlet channel 311 is arranged at the position where the vibration node P of the tool head 3 is located. There are several liquid inlet channels 311, and the several liquid inlet channels 311 are evenly arranged along the circumference of the tool head 3. The ultrasonic vibration curve is shown as S. The amplitude is the largest in the dispersion part, and the amplitude at the vibration node P is close to zero.

[0034] Furthermore, the transmission channel 321 is arranged along the axial direction of the tool head 3 and is arranged perpendicular to the liquid inlet channel 311. The mixed liquid is poured into the transmission channel 321 inside the tool head 3 through the liquid inlet channel 311. When the tool head 3 is ultrasonically vibrated, the mixed liquid will vibrate in the transmission channel 321, so that the mixed liquid is homogeneously dispersed.

[0035] Furthermore, a plug 322 is installed at one end of the transmission channel 321, and the other end is connected to the liquid outlet channel 331. The plug 322 can prevent the mixed liquid in the transmission channel 321 from leaking, thereby ensuring the internal sealing of the tool head 3.

[0036] In some embodiments of the present application, when the tool head 3 ultrasonically vibrates in the axial direction, the mixed liquid inside the tool head 3 reciprocates along the transmission channel 321, converts electrical energy into mechanical vibration through the transducer, and adjusts the amplitude of the mechanical vibration through the amplitude modulator to convert low-frequency vibration into high-frequency vibration, which is then transmitted to the tool head. Through the high-frequency ultrasonic vibration of the tool head, the internal mixed liquid can be efficiently and quickly dispersed, emulsified and homogenized, the number of repeated dispersions of the mixed liquid is reduced, the dispersion effect is improved, and the purpose of preparing a mixed liquid with a smaller particle size is achieved.

[0037] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0038] The above description is only a detailed description of the preferred embodiments and principles of the present application. For ordinary technicians in this field, there will be changes in the specific implementation methods based on the ideas provided by the present application, and these changes should also be regarded as the scope of protection of the present application.
