Tehnički problem Technical problem

Tehnički problem koji se rješava ovim« izumom sastoji se u slijedećem: kako riješiti signaliziranje gornjeg ili donjeg nivoa tekućine u spremniku, da bi se ostvario nadzor ili regulacije nivoa u prostorima ugroženim eksplozijom, primjenom signalizatora nivoa koji zadovoljava zahtjeve rada u takvom prostoru. The technical problem that is solved by this invention consists in the following: how to solve the signaling of the upper or lower level of the liquid in the tank, in order to achieve monitoring or regulation of the level in areas threatened by an explosion, using a level indicator that meets the requirements of working in such an area.

Stanje tehnike State of the art

Dosadašnji uređaji koji se koriste kao signalizatori nivoa pomoću plovka rade tako da promjena položaja plovka preko polužnog mehanizma obavlja promjenu stanja sklopke koja otvara ili. zatvara strujni krug nadzora ili regulacije nivoa. U slučaju da se želi vršiti regulacija nivoa u prostorima ugroženim eksplozijom treba sklopka biti odvojena od signalizatora tako da nema mogućnosti da iskra nastala kod otvaranja ili zatvaranja kontakata sklopke bude u eksplozivnoj atmosferi. Kod signalizatora nivoa prijavljenog ovom prijavom dio plovka sa polužnim mehanizmom odvojen je pregradom od sklopke. Sklopka je izvedena u "S" izvedbi tako da je opasnost od eksplozije izbjegnuta. Previous devices that are used as level indicators using floats work so that changing the position of the float via the lever mechanism changes the state of the switch that opens or. closes the monitoring or level regulation circuit. In the event that it is desired to regulate the level in areas threatened by an explosion, the switch should be separated from the signalizer so that there is no possibility that the spark created when the switch contacts are opened or closed is in an explosive atmosphere. In the case of the level indicator reported with this report, the part of the float with the lever mechanism is separated from the switch by a partition. The switch is made in the "S" version so that the risk of explosion is avoided.

Opis rješenja tehničkog problema Description of the solution to the technical problem

Na crtežu signalizatora nivoa prikazano je slijedeće: The drawing of the level indicator shows the following:

Slika 1 prikazuje nacrt signalizatora nivoa Figure 1 shows the outline of the level indicator

Slika 2 prikazuje tlocrt signalizatora nivoa Figure 2 shows the floor plan of the level indicator

Signalizator nivoa sastoji se od tijela 1 sa prirubnicom 1.1. Na tijelu 1 je urezan navoj 1.2 kojim se signalizator nivoa učvrsti na spremnik tekućine. Položaj signali šatora nivoa na spremniku određuje tehnološkim zahtjevom (signaliziranje maksimalne vrijednosti, minimalne ili neke druge). Na tijelo 1 učvrsti se vijcima 2 poklopac 3. Brtvljenje tijela 1 i poklopca 3 izvedeno je brtvom 4. Na poklopcu 3 izvedene su 2 konzole 5 međusobno povezane sa odstojnim komadima 5.1. Poklopac 3 ima uglodan utor 3.1. oblika kružnog odsječka. Utorom 3.1. prolazi permanentni magnet 6 učvršćen na polugu 7. Poluga 7 je okretna oko ležaja 6 učvršćenog u konzole 5. Na kraju poluge 7 nasuprot magnetu nalazi se plovak 9. The level indicator consists of a body 1 with a flange 1.1. On the body 1, a thread 1.2 is cut, which fastens the level indicator to the liquid tank. The position of the level tent signals on the tank is determined by the technological requirement (signalling of the maximum, minimum or other value). Cover 3 is fixed to body 1 with screws 2. Body 1 and cover 3 are sealed with gasket 4. Cover 3 has 2 consoles 5 connected to each other with spacers 5.1. Cover 3 has a polished groove 3.1. in the form of a circular section. Slot 3.1. the permanent magnet 6 fixed to the lever 7 passes through. The lever 7 is rotatable around the bearing 6 fixed to the console 5. At the end of the lever 7 opposite the magnet there is a float 9.

Dizanje ili spuštanje nivoa tekućine diže ili spušta plovak 9 koji preko poluge 7 pomiče magnet 6 u utoru 3.1 poklopca 3. Sa vanjske strane poklopca 3 učvršćena je magnetska sklopka 10. Prolazom magneta 6 u utoru 3.1 poklopca 3 uz magnetsku sklopku 10 u sklopu se izvrši promjena položaja kontakta (kontakti se zatvore ili otvore). Raising or lowering the liquid level raises or lowers the float 9, which moves the magnet 6 in the slot 3.1 of the cover 3 via the lever 7. A magnetic switch 10 is fixed on the outside of the cover 3. By passing the magnet 6 in the slot 3.1 of the cover 3 next to the magnetic switch 10 in the assembly, change of contact position (contacts close or open).

Ta promjena položaja šalje dalje informaciju u regulacijski ili signalizacijski dio. This change in position sends further information to the regulatory or signaling part.

Najbolji način za privrednu upotrebu The best way for commercial use

Izradu signalizatora nivoa može izvršiti osoba sa prosječnim znanjem i stručnošću sa područja obrade metala skidanjem strugotine i montaže strojnih elemenata. Kod obrade treba pripaziti na izradu navoja na tijelu signalizatora kako bi se signalizator mogao ugraditi na spremnik. Osim toga zasor između permanentnog magneta i utora poklopca mora biti mali, ali se ne smije desiti, da magnet zapinje u poklopac. Poklopac mora biti izveden iz nemagnetizirajućeg materijala. Dimenzije poklopca i tijela signalizatora moraju biti dimenzionirane tako da podnesu tlakove u spremniku ukoliko su ti tlakovi veći od atmosferskog. Nalijeganje poklopca na tijelo signalizatora mora biti dobro izvedeno i dobro brtvljeno tako da propuštanje plina, pare ili tekućine iz spremnika nije moguće. A level indicator can be made by a person with average knowledge and expertise in the field of metalworking by removing shavings and assembling machine elements. During processing, care should be taken to create threads on the body of the signaling device so that the signaling device can be installed on the container. In addition, the gap between the permanent magnet and the groove of the cover must be small, but it must not happen that the magnet gets stuck in the cover. The cover must be made of non-magnetizing material. The dimensions of the cover and the body of the signaling device must be dimensioned so that they can withstand pressures in the tank if these pressures are higher than atmospheric. The fitting of the lid on the body of the signalizer must be well done and well sealed so that gas, vapor or liquid leakage from the tank is not possible.
