Abstract
Dýchací filter s magnetickou vložkou je určený na ochranu dýchacích ciest před oceloliatinovým prachom a pozostáva zo sitka z magneticky mSkkej ocele, ktoré je uložené do magnetického póla permanentného magnetu. Ocelové sítko je od magnetu oddělené vložkou. Permanentný magnet, ocelové sitko a doplňkový porézny materiál tvoria jeden celok upevněný pomocou matice ku základovéj doske. Základová doska je súčasťou lícnice. V základovej doske je umiestnený vdychovací ventil. Vdychovaci ventil je súčatou lícnice.Breathing filter with magnetic insert is designed to protect the respiratory tract from steel dust and consists of a sieve made of magnetically m steel, which is stored in magnetic permanent magnet pole. Steel the strainer is separated from the magnet by an insert. Permanent magnet, steel strainer and complementary porous the material forms one unit fixed by the matrix to the base plate. Base plate is part of cheekpiece. It is in the motherboard an inhalation valve located. Inhalation valve is a part of the cheekpiece.
Description
Vynález sa týká dýchacieho filtra s magnetickou vložkou zachytávájúcou ocelový prach.BACKGROUND OF THE INVENTION The present invention relates to a breathing filter with a magnetic insert retaining steel dust.
Doposial dýchacie filtre obsahovali ako aktívnu vložku mechanický filter zhotovený z rázných pórovitých materiálov, ktoré mali velký tlakový spád, čo obmedzuje dobu ich použitia a nutnost náhrady znečistenej filtračnej vložky novou.Until now, breathing filters have included a mechanical filter made of vigorous porous materials having a large pressure drop as an active cartridge, limiting their use time and the need to replace a contaminated filter cartridge with a new one.
Podstata dýchacieho filtra podlá vynálezu spočívá v tom, že požostáva z telesa lícnice, ku ktorej je připevněná základová doska, ktorej súčastou je vdychovací ventil, pričom v základovej doske je uložený permanentný magnet, ktorý je od ocelového kruhového sitka oddělený vložkou, kde šito, vložka a permanentný magnet sú upevněné k základovej doske maticou a súčastou lícnice je vydychovací ventil a medzi 2ákladovú došku a permanentný magnet je vložený dolpňkový porézny materiál.The essence of the breathing filter according to the invention is that it consists of a cheekpiece to which a base plate is attached, which includes an inhalation valve, wherein the base plate houses a permanent magnet which is separated from the steel circular sieve by a liner where the sewn, liner and the permanent magnet is secured to the base plate by a nut, and the cheekpiece includes an exhalation valve and an expanded porous material is inserted between the 2-base thatch and the permanent magnet.
Výhodou dýchacieho filtru s magnetickou vložkou je menší odpor pri vdychovaní, dokonalé čistenie, jednoduché ošetrenie a obsluha.The advantage of the breathing filter with magnetic insert is lower inhalation resistance, perfect cleaning, easy treatment and operation.
Dýchací filter podlá vynálezu je vhodný na ochranu zdravia pracovníkov, pracujúcich dlhodobo v prostředí znečistenom ocelovým prachom suchým (zlievárne, prach z brúsenia odliatkov a pod).The breathing filter according to the invention is suitable for the protection of the health of workers working for a long time in an environment contaminated with dry steel dust (foundries, casting grinding dust, etc.).
Dýchací filter podlá vynálezu je zobrazený na priloženom obrázku.The breathing filter according to the invention is shown in the attached figure.
Kovové ocelové .sítko J z magneticky makkého materiálu je uložené v poli permanentného magnetu 2. Ocelové sítko _1 je od magnetu oddělené vložkou Jav základovej doske 4_ je tiež vdychovací ventil J ako súčast celej vdychovacej sústavy. Základová doska 4 je súčastou lícnice J. Vydychovací ventil 1_ je tiež súčastou lícnice J. Doplňkový porézny materiál 9 je vložený medzi magnet J a základová došku J. Matica J tvoří obal vdychovacej sústavy, v ktorej je ocelové sitko J, vložka J, permanentný magnet 2, porézny materiál 9_, a vdychovací ventil 6.The metal steel mesh 1 of the magnetically pliable material is embedded in the field of the permanent magnet 2. The steel mesh 1 is separated from the magnet by the liner J of the base plate 4. The inhalation valve 4 is also part of the entire inhalation assembly. The base plate 4 is part of the cheekpiece J. Exhalation valve 7 is also part of the cheekpiece J. A supplementary porous material 9 is inserted between the magnet J and the base thatch J. The nut J forms the envelope of the inhalation assembly in which the steel sieve J is inserted. 2, a porous material 9, and an inhalation valve 6.
Usměrněný prúd vdychovaného vzduchu prechádza cež‘ocelové sítko J. Ocelový prach obsiahnutý vo vzduchu je na zmagnetizovanom sitku JL zachytávaný. Zložením sitka J a jeho vrstvením je podlá potřeby zachytávaný aj iný ako ocelový prach. Doplňkový porézny materiál 9 zachytává zbytkové nečistoty.A rectified flow of inhaled air passes through a steel screen J. Steel dust contained in the air is collected on the magnetized screen JL. The composition of the sieve J and its layering also collects other than steel dust as required. The additional porous material 9 retains residual impurities.
