Description
Technical field
The present invention relates to the generation of general mechanical oscillation or transmit technical field, especially relate to piezo-electric effect and utilize electric energy to produce hyperacoustic mechanical vibration equipment.
Background technology
We successfully are applied to ultrasonic technology the extracts active ingredients aspect of Chinese herbal medicine, but find that in use present ultrasonic transducer still exists following several respects defective: the one, selected ultrasonic transducer is the trumpet-shaped transducer that was used to clean tank body in the past, high directivity, its one-way for a change, once adopted with polyhedron trumpet-shaped transducer was installed, though situation makes moderate progress, volume increases, and effect is still undesirable; The 2nd, do not possess performance explosion-proof, flame proof, and in the traditional Chinese medicine extraction process in order to extract different effective ingredients, again best different solvents of corresponding solubility that adopt more, these solvents all are inflammable, explosive basically, or even the medium of toxic property, so use this class transducer to exist potential safety hazard.
Summary of the invention
The objective of the invention is problem at above-mentioned prior art existence, a kind of traditional Chinese medicine extraction jar that is fit to place is provided, its radially 360 ° comprehensive can send the uniform ultrasonic wave of intensity, and can adapt to that it is inflammable accordingly, explosive, even the solvent of toxic property, the large-power supersonic transducer that can quicken the stripping extraction of effective components of Chinese medicinal.
For achieving the above object, technical scheme of the present invention is such: a kind of large-power supersonic transducer, shell is the cylindrical tube that stainless steel is made, cylindrical shell two ends is up and down lived with the flange disk seal, this cylindrical shell the latter half is outer pressure inlet, outside in the pressure inlet sheathed in pressure inlet, the lower end and the lower flange of interior pressure inlet are fixed, the upper end is sealed by the division board that is fixed in cylinder inboard wall; Form inner chamber between the inside and outside pressure inlet, in evenly distributed mode a plurality of ultrasonic wave transducer elements are installed in inner chamber, this element is the piezoelectric ceramics of ring-type, waters the seal ring epoxy resins between the piezoelectric ceramics in inner chamber, to reach piezoelectric ceramics is fixed, and with the purpose of bore seal, insulation; On the annular inside and outside wall of piezoelectric ceramics, draw two leads of positive and negative electrode respectively, this lead connects with binding post on the insulation board that is fixed in cylindrical shell the first half, the cylinder inboard wall of this part, insulation board, binding post and lead water sealingization by epoxy resin together, make it to seal with external insulation; Lead is connected with power supply by Explosion proof joint by outgoing cable.
Owing to adopted technique scheme, a kind of large-power supersonic transducer of the present invention, when being used to extract effective components of Chinese medicinal, the various liquid phases that can put into the traditional Chinese medicine extraction jar are inflammable, explosive, the liquid vehicle of poisonous and harmful solvent such as ethanol, benzinum, chloroform etc. is worked, and can radially send the uniform ultrasonic wave of intensity in 360 ° of scopes, its volume is little, the effect height; Simultaneously can be applied to the cleaning and the eliminating sludge in pipe of biochemical biological emulsification, equipment by effects such as hyperacoustic cavitation, mechanical oscillation.
