Description
Oblasť technikyTechnical field
Vynález sa týka zariadenia na zisťovanie miery zanesenia filtračnej plachtičky bubnového filtra.The invention relates to a device for detecting the degree of clogging of a filter cloth of a drum filter.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Stupeň zanesenia filtračných plachtičiek je doposiaľ signalizovaný zariadeniami pracujúcimi na princípe merania rozdielu hladín pred a za filtrom pomocou plavákových spínacích a vypínacích systémov, prípadne elektronických alebo tlakových snímačov. Nevýhodou doposiaľ známych systémov je ich nadmerná zložitosť a neúmerná cena. Naviac vo väčšine prípadov majú nedostatočne spoľahlivú funkciu a malú citlivosť. Počas prevádzky filtra dochádza otáčaním filtračného bubna a jeho technologickou činnosťou k zvlneniu hladiny, a tým k nesprávnemu okamihu signalizácie doposiaľ používanými systémami.So far, the degree of clogging of filter cloths has been signaled by devices operating on the principle of measuring the difference in levels before and after the filter by means of float switch-on and switch-off systems or electronic or pressure sensors. The disadvantages of the hitherto known systems are their excessive complexity and disproportionate cost. In addition, in most cases they have insufficiently reliable function and low sensitivity. During the operation of the filter, the filter drum rotates and its technological activity ripples the level, and thus the incorrect moment of signaling by the systems used so far.
Rozdiel hladín sa prejavuje vyšším zaťažením kladky 3. Táto hodnota sa prenáša cez páku 5 na snímač 7 sily a slúži ako východiskový údaj pre nezobrazenú riadiacu jednotku, ktorá určí zodpovedajúce otáčky hnacieho elektromotora pohonu otáčania filtračného bubna 1, prípadne môže signalizovať nebezpečné prevádzkové stavy.The difference in levels results in a higher load on the pulley 3. This value is transmitted via the lever 5 to the force sensor 7 and serves as a starting point for the control unit not shown, which determines the corresponding speed of the drive motor of the filter drum rotation drive.
Snímač 7 sily môže byť založený na princípe merania sily.The force sensor 7 may be based on the force measurement principle.
Je výhodné, ak je snímač 7 sily umiestnený priamo pod ložiskom 4, pričom páka 5 nemusí byť použitá.It is preferred that the force sensor 7 is located directly below the bearing 4, the lever 5 not having to be used.
Snímače sily 7 však môžu byť umiestnené v oboch koncoch filtračného bubna I.However, force sensors 7 may be located at both ends of the filter drum I.
Podstata vynálezuSUMMARY OF THE INVENTION
Uvedené nedostatky sú odstránené v zariadení na zisťovanie miery zanesenia filtračnej plachtičky bubnového filtra podľa vynálezu, ktorého podstata je v tom, že na nepohyblivom ráme filtra je upevnený snímač sily, spojený s ložiskom, na ktorom je otočné osadená kladka, na ktorej je zavesený nosný element obklopujúci v spodnej časti jednu stranu filtračného bubna. Ložisko môže byť opreté o páku, ktorá má jeden koniec upevnený výkyvné na nepohyblivom ráme filtra a druhý koniec spojený so snímačom sily.These drawbacks are eliminated in a device for detecting the degree of clogging of a filter filter drum according to the invention, which is characterized in that a fixed sensor frame is mounted on a stationary filter frame connected to a bearing on which a rotatably mounted pulley on which the support element is suspended surrounding at the bottom one side of the filter drum. The bearing may be supported by a lever having one end mounted pivotably on a stationary filter frame and the other end connected to a force sensor.
Výhoda zariadení podľa vynálezu je v tom, že výška hladiny pritekajúcej filtrovanej kvapaliny je zisťovaná odvodene z váhy kvapaliny vnútri filtračného bubna a rozdielom hladín pritekajúcej a odtekajúcej kvapaliny. Vzhľadom na to, že túto váhu neovplyvňuje zvlnenie hladiny, je zisťovanie rozdielu hladín veľmi presné, mimoriadne spoľahlivé a pritom jednoduché.An advantage of the devices according to the invention is that the level of the inflow of the filtered liquid is determined by the weight of the liquid inside the filter drum and the difference of the inflow and outflow levels. Since this weight is not influenced by the ripple of the level, it is very accurate, extremely reliable and easy to detect the level difference.
