Description

CS 269035 B1 1CS 269035 B1 1

Vynález sa týká upevňovacieho prvku ultrazvukového žiariča pre tekutinové pro—vstredie. U doteraz znáBych ultrazvukových člstiacich zarladeni sa vykonává upevňovanieultrazvukových meničov priamo na steny nádoby lepením. Známe sú aj rleáenia u ktorýchea na čistlace vane upevňujú membrány s nalepenými ultrazvukovými meničmi do akustické-ho okna. Nevýhodou takýchto rieáení je tá skutečnost, že už pri lepení ultrazvukovýchmeničov ne membrány dochádza k deformáciam vyžiarovacích stien. Ďaláou nevýhodou lepe-ného spoja je, že limituje životnost zariadenia. Velmi často dochádza k jeho poákodeniuhlavně pri vyááích pracovných teplotách a vyááích úrovniach budenia. Nevýhodou je i to,že v tomto spoji dochádzakakustickým stratám, čím sa znižuje elektroakustická účinnost.BACKGROUND OF THE INVENTION The present invention relates to an ultrasonic radiator fastener for fluidized media. In the ultrasonic yoke known to date, fixing of the ultrasonic transducers is carried out directly on the container walls by gluing. Also known are cleaning in which the membranes with the ultrasonic transducers glued to the acoustic window are attached to the tub. The disadvantage of such solutions is the fact that, even when bonding ultrasonic transducers to the diaphragm, radiation walls are deformed. Another disadvantage of the adhesive bond is that it limits the life of the device. Very often, its damage occurs mainly when the working temperatures are raised and the excitation levels rise. A disadvantage is also the fact that in this connection, there are acoustic losses, thus reducing electroacoustic efficiency.

Vyááie uvedené nevýhody zmierňuje a technický problém rieái upevňovací prvok ultra-zvukového žiariča pre tekutinové prostredie podlá vynálezu, ktorého podstata spočíváv tom, že vlnovod ultrazvukového žiariča je na obvode vyžarovacej časti opatřený upevňo-vacou přírubou. Upevňovacia příruba je opatřené závitom. Medzi vlnovodom a upevňovacoupřírubou je vytvořené vybranie.The above-mentioned disadvantages are alleviated and the technical problem is solved by an ultra-sound radiator fastener for the fluid environment according to the invention, the principle of which is that the waveguide of the ultrasonic radiator is provided with a mounting flange at the periphery of the radiating portion. The mounting flange is threaded. A recess is formed between the waveguide and the mounting flange.

Upevňovacím prvkom ultrazvukového žiariča podlá vynálezu sa docieli jednoduchýma nenáročným provedením vysokej elektroakustickej účinnosti. Výhodou je aj neobmedzenáživotnost pri vysokých úrovniach budenia, ako i vysokej pracovnej teplote použitéhopracovného média. Vynólezom sa zníži pracnost pri výrobě ultrazvukových meničov a zvýšisa variabilita ultrazvukových zariadení.The ultrasonic emitter fastener of the present invention achieves high electro-acoustic efficiency by simple, simple design. The advantage is also the unlimited lifetime at high levels of excitation as well as high working temperature of the processing medium used. It has been proposed that the ultrasonic transducer production will be less labor intensive and ultrasound devices will be more variable.

Na připojených výkresoch sú znázorněné tri příkladné rleáenia podlá vynálezu,kdena obr. 1 je nakreslený upevňovací prvok ultrazvukového žiariča v řeze s vonkajSím závi-tom pre priarae naskrutkovanie na pracovnú nádobu, na obr. 2 je nakreslený upevňovacíprvok ultrazvukového žiariča v řeze a uchytený na pracovnej nádobě prostredníctvom ma-tice a na obr. 3 je nakreslený rez upevňovacieho prvku ultrazvukového žiariča uchytené-ho na stene pracovnej nádoby prostredníctvom skrutiek.In the accompanying drawings, three exemplary embodiments of the invention are shown, wherein: Figure 1 is an ultrasonic radiator mounting element in cross-sectional view for screwing onto a working vessel, Figure 2 shows the ultrasonic radiator fixing element in section and attached to a working FIG. 3 is a cross-sectional view of the ultrasonic radiator mounting element attached to the wall of the working vessel by means of screws.

Ultrazvukový žiarlč pre tekutinové prostredie podlá obr. 1 pozostáva z vlnovodu 1,opatřeného po obvode upevňovacou přírubou 2. Upevňovacia příruba 2 má na hornom koncivytvořené osadenie opatřené závitom 4 a medzi upevňovacou přírubou 2 a vlnovodom 1 jevytvořené vybranie 3. Prostredníctvom závitu 4 je ultrazvukový měnič zaskrutkovanýv otvore steny 5 pracovnej nádoby, pričom medzi upevňovacou přírubou 2 a stěnou 5 pra-covnej nádoby je uložené tesnenie 11. Prostredníctvom skrutky 6 sú na vlnovode i pri-skrutkované s mechanickým predpátím piezokeraraické meniče 7 medzi ktorými je uloženéprívodná elektroda 9. Na piezokeramických meničoch 7 je uložený reflektor 8.The ultrasonic lamp for the fluid environment according to FIG. 1 consists of a waveguide 1 provided circumferentially with a mounting flange 2. The mounting flange 2 has a thread 4 on the upper configuration and a recess 3 is formed between the mounting flange 2 and the waveguide 1. The thread 4 is an ultrasonic transducer screwed in the opening of the wall 5 of the working vessel, wherein a seal 11 is arranged between the fixing flange 2 and the wall 5 of the working vessel. By means of the screw 6, the piezoceramic transducer 7 between which the inlet electrode 9 is mounted is screwed to the waveguide with mechanical prestressing. 7 is a reflector 8.

Druhé rieáenie podlá obr. 2 je zhodné s predchédzaujúcim s tým rozdielom, že v otvo-re steny 5 pracovnej nádoby je zasunutá upevňovacia příruba-2, ktorá má osadenie so zá-vitom 4 vytvořené na dolnom konci a je uchytená prostredníctvom matice io.The second solution according to FIG. 2 is identical to the preceding one, except that a mounting flange-2 is inserted in the opening of the working container wall 5, which has a shoulder 4 in the lower end and is fastened by a nut 10.

Tretie rieáenie podlá obr. 3 je zhodné s druhým rieáením s tým rozdielom, že upev-ňovacia príruba 2 bez osadenia priamo dosedá .na stenu 5 pracovnej nádoby, v upevňovacejpřírubě sú vytvořené otvory 13 opatřené závitom 4. Upevňovacia príruba 2 je na stene 5pracovnej nádoby uchytená prostredníctvom upevňovacích skrutiek 12 a otvorov 13.The third solution according to FIG. 3 is identical to the second solution, with the difference that the mounting flange 2 sits directly on the wall 5 of the working vessel without holes, the holes 13 are provided in the fixing flange 4. The fixing flange 2 is on the wall of the working vessel fastened by fastening screws 12 and holes 13.

Takto upevněný ultrazvukový žiarič vyžaruje ultrazvuková energiu priamo do prostre-dia pracovnej nádoby.The ultrasonic emitter thus mounted emits ultrasonic energy directly into the working vessel environment.

Upevňovací prvok ultrazvukového žiariča je možné použit najma tam, kde sa pri pra-covných technológlach používajú vysoké výkonové úrovně pri vysokých pracovných teplotách.The ultrasonic emitter fastener may be used especially where high power levels are used in high-temperature operating processes.
