Description
Vynález sa týká granulácie sypkých hmSt a rieši problém prstencovej matrice granulátora a válcovou furikčnou plochou.The invention relates to granulation of bulk materials and solves the problem of the annular matrix of the granulator and the cylindrical furrier surface.
Prstencové matrice granulátorov sa v súčasnej době vyrábajú z jedného kusá materiálu, pričom válcová funkčná plocha a vstupy do kuželových lisovacích otvorov sa tepelne spracovávajú povrchovým kalením do híbky niekoíko milimetrov.The annular matrices of the granulators are presently manufactured from one piece of material, with the cylindrical functional surface and the entrances to the conical press holes being heat treated by surface hardening to a depth of several millimeters.
Po opotřebení tepelne spracovanej vrstvy áalší priebeh opotrebenia je veími rýchly a vedie k vyradeniu matrice. Toto je nevýhodné, nakoíko sa využije pre pracovný proces iba 3 až 7 % materiálu matrice, ktorá sa vyraduje celá.After wear of the heat-treated layer, the further course of wear is very rapid and leads to discarding of the matrix. This is disadvantageous since only 3 to 7% of the matrix material that is discarded entirely is used for the working process.
Uvedené nevýhody odstraňuje prstencová matrica granulátora, vhodná najma pre granulá ciu sypkých hmot, ktorej podstata spočívá v tom, že pozostáva z prvej hlavnej časti, do ktorej je vsunutá druhá hlavná časí a tieto časti sú dotlačené k sebe príložkou a vekom za pomoci skrutiek zoskrutkovaných do otvorov so závitom vytvořených v prvej hlavnej časti.The above-mentioned disadvantages are eliminated by an annular granulator matrix suitable, in particular, for the granulation of loose materials, which consists in that it consists of a first main part in which the second main part is inserted and these parts are pressed together by a shim and a lid using screws screwed into threaded holes formed in the first main portion.
Prstencová matrica granulátora podía vynálezu umožňuje po opotřebení funkčnej časti túto vymenií. Výhodou je tiež skutočnosť, že zmenšením telesa funkčnej časti sa zmenšia i pro blémy pri tepelnom spracovaní, najma z híadiska rozloženia napatí a tým i vzniku možných prasklin a havárií.The annular matrix of the granulator according to the invention allows this replacement after wear of the functional part. An advantage is also the fact that by shrinking the body of the functional part it will also reduce for heat treatment problems, especially in terms of the distribution of stresses and thus the occurrence of possible cracks and accidents.
Příklad matrice, ktorá je predmetom ochrany je schematicky znázorněný na pripojenom výkrese v čiastočnom bokorysnom řeze.An example of a matrix to be protected is schematically shown in the attached drawing in partial side section.
Prstencová matrica granulátora sa skládá z prvej hlavnej časti 1, do ktorej je vsunutá druhá hlavná časí 2 s válcovými, funkčnými otvormi a obe sú k sebe dotlačené príložkou 2 a vekom 4 pomocou skrutiek 5, zaskrutováných do otvorov so závitom vytvořených v prvej hlavnej časti 1. Správná poloha druhej hlavnej Časti 2 s funkčnými otvormi-je oproti otvoromThe annular die of the granulator consists of a first main body 1, in which a second main body 2 with cylindrical, functional openings is inserted and both are pushed together by a shim 2 and a lid 4 by means of screws 5 screwed into threaded holes formed in the first main body 1 The correct position of the second main part 2 with functional openings is opposite the openings

Výhodou prsteneověj matrice granulátora podía vynálezu je, že po opotřebení druhej hlavnej časti 2 s funkčnými otvormi sa táto dá íahko vyměnil a nie je potřebná vyřadil eelú matřiou. Z híadiska opotrebenia a životnou i matrice je doležitá i skutečnosl, že pre zhotovenie druhej hlavnej časti 2 s funkčnými otvormi je možné volil kvalitnější legovaný materiál zabezpečujúci oveía menšie opotrebenie. Zmenšením hmotnosti druhej hlavnej časti 2 s fukčnými otvormi sa zmenšia i problémy a náročnosl pri tepelnom spracovaní. íalšou výhodou je, že je na menšíoh telesách možné funkčné otvory elektrochemicky vyleštil, skrátil dobu zábehu matrice a tým zvýšil jej výkon aživotnosl.An advantage of the ring granulator according to the invention is that after the wear of the second main part 2 with the functional openings, this is easily replaced and it is not necessary to dispose of the entire matrix. From the point of view of wear and life and the matrix, it is also important that for the production of the second main part 2 with functional openings it is possible to choose a higher quality alloy material ensuring much less wear. By reducing the weight of the second main part 2 with the blowing openings, the heat treatment problems and complexity are also reduced. Another advantage is that on smaller bodies it is possible to polish the functional holes electrochemically, shorten the run-in time of the matrix and thereby increase its performance and lifetime.
Možnosti využitia prstencovej matrice granulátora podía vynálezu sú najma v poínohospodírstve pri výrobě tvarovaných krmných zmesi a v r&znych odvetviaoh potravinářského a chemického priemyslu.Possibilities of using the annular granulator of the present invention are particularly in agriculture in the production of molded feed mixtures and in various sectors of the food and chemical industries.
