Abstract

Očelom riešenia je zabezpečenie dostatočnej pružnosti membrány. Uvedeného účelu sa dosahuje riešením, ktorého podstatou je, že na membráně je nad obvodom ultrazvukového meniča vytvořené aspoň z jednej strany vybranie.The purpose of the solution is to ensure sufficient elasticity of the membrane. The stated purpose is achieved by a solution, the essence of which is that a recess is formed on the membrane above the circumference of the ultrasonic transducer on at least one side.

Description

Vynález sa týká ultrazvukového žiariča najma pre tekutinové prostredie. U doteraz známých ultrazvukových čistiacich zariadení sa vykonávalo upevňovanie ultrazvukových meničov priamo na steny nádoby lepením. Známe sú aj riešenia, u ktorých sa na nádobu, v ktorej sa vykonává čistiaca operácia, upevňujú membrány s nalepenými ultrazvukovými meničmi, do akustického okna. Nevýhodou takýchto riešení je tá skutočnosť, že už pri lepení ultrazvukových meničov na takto převedené membrány ultrazvukových váň dochádza k deformáciam vyzařovacích stien. Táto deformácia znižuje životnost zariadenia hlavně však pri vyšších teplotách čistiaceho média, kedy sa zvyšuje uvedená deformácia. Je možné použit hrubšie vyžarovacie steny, to však znižuje elektroakustickú účinnost zariadenia. Riešenie prostredníctvom membrán je rozměrné, čo zvyšuje potom rozměry celej čistiacej nádoby.The invention relates to an ultrasonic emitter, especially for a fluid environment. Ultrasonic cleaning equipment known to date has been used to fix ultrasonic transducers directly to the container walls by gluing. There are also known solutions in which membranes with glued ultrasonic transducers are fixed to an acoustic window on the vessel in which the cleaning operation is carried out. The disadvantage of such solutions is the fact that, even when ultrasonic transducers are bonded to the ultrasonic membranes thus transferred, radiation walls are deformed. This deformation reduces the life of the device mainly at higher temperatures of the cleaning medium, whereby said deformation increases. Thicker radiant walls can be used, but this reduces the electroacoustic efficiency of the device. The solution through the membranes is large, which in turn increases the size of the entire cleaning vessel.

Vyššie uvedené nedostatky zmierňuje a technický problém rieši ultrazvukový žiarlč najma pre tekutinové prostredie podlá vynálezu, ktorého podstatou je, že na membráně je nad obvodom ultrazvukového meniča vytvořené aspoň z jednej strany vybranie.The above-mentioned drawbacks are alleviated and the technical problem is solved by an ultrasonic lamp, especially for a fluid environment according to the invention, which has at least one recess on one side of the ultrasonic transducer.

Ultrazvukovým žiaričom, najma pre tekutinové prostredia podlá vynálezu sa docieli toho, že vyžarujúca stená může byť dostatočne hrubá, takže je tu možnost' dostatočne ju obrobit za účelom kvalitného akustic- kého prilepenia ultrazvukového meniča. Obvodové vybranie zaisťuje dostatočnú pružnost membrány, takže sa dosiahne vysoká elektroakustická účinnost. Výhodou žiariča je, že sa vyskytujú minimálně deformácie vyžarujúcej membrány pri vyšších pracovných teplotách a hrubá vyžarujúca membrána zvyšuje životnost žiariča v závislosti na kavitácii.The ultrasonic emitter, especially for the fluid environments of the present invention, ensures that the radiating wall can be sufficiently thick so that it can be machined sufficiently to provide a soundproofing of the ultrasonic transducer. The peripheral recess provides sufficient membrane flexibility so that high electroacoustic efficiency is achieved. The advantage of the emitter is that there are at least deformations of the radiating membrane at higher operating temperatures, and the thick radiating membrane increases the lifetime of the radiator depending on cavitation.

Na pripojenom výkrese sú znázorněné dve příkladné riešenia, kde na obr. 1 je ultrazvukový žiarič nakreslený v řeze s vybráním membrány na hornej ploché a na obr. 2 je ultrazvukový žiarič nakreslený v řeze s vybráním membrány na dolněj ploché.In the accompanying drawing, two exemplary solutions are shown, wherein in Fig. 1 the ultrasonic emitter is drawn in cross-section with a membrane recess on the upper flat and in Fig. 2 is an ultrasonic emitter drawn in section with a diaphragm recess on the lower flat.

Ultrazvukový žiarič (obr. lj pozostáva z ultrazvukového meniča 1 pevne uchyteného lepeným spojom 3 na membráně 5. Na hornej časti membrány 5 sú vytvořené upevňovacie otvory 2 pre uchytenie ultrazvukového žiariča da okna čistiacej vane, na obr. nezakreslené. Na hornej ploché membrány 5 nad obvodom ultrazvukového meniča 1 je vytvořené vybranie 4.The ultrasonic emitter (FIG. 1j consists of an ultrasonic transducer 1 fixedly fixed by a glued joint 3 on the membrane 5. On the upper part of the diaphragm 5 there are fixing holes 2 for fixing the ultrasonic radiator to the window of the cleaning tub, not shown in the figure. a recess 4 is formed by the periphery of the ultrasonic transducer 1.

Druhé riešenie ultrazvukového žiariča (obr. 2) je zhodné s prvým riešením, pričom vybranie 4 je vytvořené na dolnej ploché membrány 5.The second solution of the ultrasonic emitter (Fig. 2) is identical to the first solution, the recess 4 being formed on the lower flat membrane 5.

Ultrazvukový žiarič podlá vynálezu je možné použit najma tam, kde sa pri pracovných technológiach používá vyššia pracovná teplota pri vysokých výkonových úrovniach ultrazvukového meniča 1, pri požadovanej vysokej životnosti celého zariadenia.The ultrasonic emitter according to the invention can be used especially where a higher working temperature is used in the working technologies at high power levels of the ultrasonic transducer 1, with the required high lifetime of the whole equipment.
