Description
Vynález sa týká granulácie sypkých hmot a rieši problém rovinnej matrice granulátora s kužeíovou funkčnou plochou.The invention relates to granulation of bulk materials and solves the problem of the plane matrix of the granulator with a conical functional surface.
Rovinná matrice granulátorov sa v súčasnej době vyrábajú z jedného kusá materiálu z odlievaného, alebo vykovaného polotovaru. Po trieskovora opracovaní sa vo funkčnej časti robí povrchové kalenie do híbky niekoíko milimetřov. Kalená funkčná časť sa v pracovnom procese postupné opotřebovává a po opotřebení vrstvy nad 3 až 4 mra další priebeh opotrebenia je veí mi rýchly a nedobúda havarijný charakter. Po opotřebení vstupných kužeíov, připadne po deformáoii mostikov medzi otvormi sa matrica vyraáuje celá, pričom využitie materiálu je iba niekoíko hmotnostných percent.Planar matrices of granulators are currently manufactured from a single piece material from a cast or forged blank. After the shavings have been machined, a few millimeters of surface hardening are made in the functional part. The hardened functional part is gradually worn in the working process and after the layer wears above 3 to 4 m the further course of wear is very fast and does not cause an emergency character. After the inlet cones have worn out, or after the bridges between the apertures have been deformed, the matrix is punched out completely, the material utilization being only a few percent by weight.
Uvedené nedostatky sú odstránené rovinnou matricou granulátora, vhodnej najma pre granuláciu spkých hmot, ktorej podstata spočívá v tom, že matrica je delená a pozostáva z nosného telesa, funkčnej časti s otvormi a obvodovéj časti, ktoré sú spolu rozoberateíne spo jené v jeden oelok výhodné skrutkami zaistenými proti uvoíneniu poistnými podložkami.These drawbacks are overcome by the planar matrix of the granulator, suitable in particular for granulation of loose materials, which consists in that the matrix is divided and consists of a support body, a functional part with openings and a peripheral part which are detachably connected together in one shaft by screws. secured against loosening with washers.
Předmětný vynález umožňuje robiť funkčnú časť matrice granulátora s otvormi zo zliati nových ocelí podrobených zušíaschteniu v celom priereze. Týmto sa významné zvýši životnosť matric. Nosné teleso a obvodovú časť je možné zhotovovať z lackých uhlíkových ocelí, bez te pelného spracovania, nakoíko tieto vČbec nie sú vystavené opotrebeniu.The present invention makes it possible to make a functional part of the granulator matrix with die-castings of new steels subjected to drying throughout the cross-section. This significantly increases the life of the matrices. The support body and the peripheral part can be made of low carbon steels, without heat treatment, since they are not subject to wear at all.
Příklad prevedenia matrice, ktorá je predmetom ochrany je schematicky znázorněný na pri pojenom výkrese, nakreslený v čiastočnom řeze.An exemplary embodiment of the matrix to be protected is schematically shown in the attached drawing, drawn in partial section.
Rodinná matrica granulátora je delená na tri časti, pričom na obvodový výstupok nesného telesa 1 dosadá odíahčenie funkčnej časti 2 s kužeíovými otvormi. Na obvodový výstupok funkčnej časti 2 dosadá odíahčenie obvodovej časti 3. Všetky tri časti sú zoskrutkované v jeden celek skrutkami 4 zaistenými proti uvoíneniu poistnými podložkami 5.The family granulator of the granulator is divided into three parts, whereby the peripheral projection of the support body 1 bears lightening of the functional part 2 with conical holes. The peripheral projection of the functional part 2 bears lightening of the peripheral part 3. All three parts are screwed together in one piece by screws 4 secured against loosening by lock washers 5.

Po opotřebení funkčnej časti 2 s otvormi sa táto časť vymění a vyřadí. Využitie materii álu sa tým výrazné zvýši, nakoíko nosné teleso 1 a obvodová časť 3 sa m8žu použiť mnohokrát. Ďalšou výhodou je, že funkčná časť 2 s otvormi sa može vyhotoviť zo špeciálnyoh zliatinovýoh ooelí a nakoíko oproti rovinnej matrici granulátora je táto iba o cca polovičnej hmotnosti, čím sa zmenšia výrazné nároky na tepelné spraoovanie, dosiahne sa priaznivejšie rozloženie vnútomých napatí a zmenší sa riziko vzniku prasklin a havárií.When the functional part 2 with holes is worn, this part is replaced and discarded. The use of the material is thereby greatly increased, since the support body 1 and the peripheral part 3 can be used many times. Another advantage is that the functional part 2 with holes can be made of a special alloy and as compared to the planar matrix of the granulator it is only about half the weight, which reduces the significant demands for thermal treatment, achieves a more favorable distribution of internal stresses and reduces the risk cracks and accidents.
Možnosti využitia rovinnej matrice granulátora podía vynálezu sú najma v poínohospodárstve pri výrobě tvarovaných krmnyoh zmesi a v rSznych odvetviach potravinářského a chemického priemyslu.Possibilities of using the planar matrix granulator according to the invention are especially in agriculture in the production of molded feed mixtures and in various branches of the food and chemical industry.
