Description

Pierwszenstwo: Zgloszenie ogloszono: 01.06.1973 Opis patentowy opublikowano: 15.10.1975 78666 KI. 5d, 1/08 MKP E21fl/08 CZYiLLNIA Urzedu Patentowego Twórcywynalazku: Jerzy Kalita, Antoni Krótki -x Uprawniony z patentu tymczasowego: Kopalnia Wegla Kamiennego „Rokitnica", Zabrze (Polska) Sposób tlumienia halasu dolowych wentylatorów lutniowych Wynalazek dotyczy sposobu tlumienia halasu wytworzonego przez wentylatory lutniowe uzywane w gór¬ nictwie podziemnym do przewietrzania wyrobisk korytarzowych.W górnictwie podziemnym stosuje sie szereg sposobów tlumienia halasu wentylatorów lutniowych. Sposo¬ by te polegaja na otoczeniu korpusu wentylatora lutniowego warstwa izolacji tlumiacej halas lub tez na dolacze¬ niu do wentylatora lutni tlumiacych.Wszystkie dotychczas stosowane sposoby tlumienia sa malo skuteczne, a dolaczenie do wentylatora lutnio¬ wego dalszych konstrukcji i urzadzen powoduje dalsze ograniczenie miejsca w poblizu skrzyzowan wyrobisk — co ze wzgledów ruchowych jest bardzo niekorzystne.Celem wynalazku jest usuniecie tych niedogodnosci. Istota wg wynalazku polega na calkowitym usunieciu wentylatora z rejonu skrzyzowania wyrobiskai zainstalowaniu go w specjalnej wnece wykonanej obok wyrobiska z oplywowym pradem powietrza, oraz na otuleniu go materialem dzwiekochlonnym.Wynalazek zostanie wyjasniony na podstawie rysunku, na którym fig. 1 przedstawia wyrobisko pomocni¬ cze, oraz lutniociag, a fig. 2 przedstawia przekrój poprzeczny przez wyrobisko glówne wraz z wyrobiskiem pomocniczym.Lutniowy wentylator 1 wraz z lutniami 2 umieszcza sie we wnece 3 wykonanej obok wyrobiska korytarzo¬ wego 4 przy czym wentylator 1 otula sie materialem dzwiekochlonnym na przyklad piaskiem.Sposób ulozenia wentylatora lutniowego wg wynalazku w duzym stopniu tlumi halas wytwarzany przez wentylator. .

In underground mining, a number of methods are used to suppress the noise of lute fans. These methods involve surrounding the body of the lute fan with a layer of noise suppression insulation or attaching to the fan silencing lutes. All the methods of suppression used so far are not very effective, and the addition of further structures and devices to the lute fan causes further limitation of the space near the intersections of workings - which is very disadvantageous for movement reasons. The aim of the invention is to eliminate these drawbacks. this way, removing the fan from the intersection of the excavation and installing it in a special recess made next to the excavation with a streamlined air stream, and covering it with sound-absorbing material. The invention will be explained on the basis of the drawing, in which Fig. 1 shows the auxiliary excavation, and the lute, and 2 shows a cross-section through the main excavation with the auxiliary excavation. The fume fan 1 with the lutes 2 is placed in the cavity 3 made next to the corridor 4, where the fan 1 is wrapped with a sound-absorbing material, e.g. sand. reduces noise generated by the fan to a great extent. .
