Abstract
Description
Vynález sa týká zariadení na zušlachťovanie lignocelulózových materiálov, najma krájaných a lúpaných dýh.The invention relates to an apparatus for upgrading lignocellulosic materials, in particular sliced and peeled veneers.
Doteraz známe zariadenía na zušlachťovanie dyhovacích materiálov pozostávajú zvačša z nádrže s otvormi na přívod a odvod zušlíachťovacieho roztoku, čerpadla a výmeníka tepla, ktorým je zabezpečné ohrievanie počas zušlachťovania.The prior art veneer refinement device consists mainly of a tank with openings for the inlet and outlet of the refining solution, a pump and a heat exchanger, which ensures heating during the refinement.
Tieto zariadenía sa najčastejšie využívajú na farbenie dyhovacích materiálov. Ich nízký výkon je zapříčiněný najma tým, že pracovný objem nádrže može byť zaplněný iba malým množstvom dýh, ktoré musia byť uložené s dodržaním značného volného priestoru medzi plochami jednotlivých dýh. Na dosiahnutie rovnoměrného prefarbenia připadá v priemere na I mm hrábky dýh medzera 3 až 6 mm.These devices are most often used for dyeing veneer materials. Their low power is due, in particular, to the fact that the working volume of the tank can only be filled with a small amount of veneer, which must be stored with considerable space between the individual veneer surfaces. In order to achieve uniform coloration, there is a gap of 3 to 6 mm per 1 mm dia.
Nízký stupeň zaplnenia týchto zariadení má za následok poměrně malá kapacitu a vysoká spotřebu vody a farbxva. Použivaníe týchto zariadení na homogenně farbenie dýh je spojené so značnými nárokmi na čistenie odpadových vod a je náročné aj na zastavená plochu.The low degree of filling of these devices results in relatively low capacity and high water and color consumption. The use of these devices for homogeneous dyeing of veneers is associated with considerable demands on waste water treatment and is also demanding on the built-up area.
Pri vyšších stupňoch zaplnenia farbiacich nádrží dýhami dochádza k nerovnoměrnému prefarbeniu materiálov hlavně na stykových miestach medzi jednotlivými dýhami a tiež na miestach, kde sa dyhy dotýkájá ostatných častí zariadenía, alebo dištančných materiálov na oddelenie dýh.At higher levels of veneer staining tanks, uneven coloration of the materials occurs mainly at the contact points between the individual veneers and also at the places where the veneer touches the other parts of the device, or spacers for separating the veneers.
Sá známe aj farbiace zariadenía na hlbkové farbenie dyhovacích materiálov pozostávajúce z farbiacej nádrže a nosiča farbených dýh, do ktorého sa před ponořením do roztoku naukladajá súbory dýh. Privod farbiaceho roztoku do farbiacej nádrže je bud otvormi v dne nádoby, alebo otvormi rúrok, ktoré sá upevněné v blízkosti stien farbiacej nádoby.Also known is a dyeing device for deep dyeing veneer materials consisting of a dyeing tank and a carrier of dyed veneers, into which veneer sets are deposited prior to immersion in the solution. The delivery of the dye solution to the dye tank is either through the holes in the bottom of the container or through the holes of the tubes which are fixed near the walls of the dyeing container.
V snahe zabezpečit/ rovnoměrnější přísun farbiaceho roztoku na celé plochy jednotlivých dýh bolo navrhnutých viacero sposobov a zariadení, ktoré sá založené buá na principe pohybu nosiča s dýhami vo farbiacom roztoku, usměrněným pródením farbiacej kvapaliny, alebo prívodom plynov do farbiaceho roztoku.In order to ensure a more uniform supply of the dye solution over the entire surface area of the individual veneers, several methods and devices have been proposed which are based either on the movement of the veneer carrier in the dye solution, by rectifying the dye liquid.
Nevýhodou popisovaných zariadení na zabezpečeníe rovnomernejšieho prefarbenia je bu3 značná výrobná náročností, malá účinností, alebo nemožností adaptovania do už vyrobených zariadení.The disadvantages of the described devices to ensure more uniform coloration are either a considerable manufacturing effort, low efficiency or an impossibility to adapt to already manufactured devices.
Uvedené nedostatky odstraňuje, připadne do značnej miery zhižuje zariadenie na zušlachťovanie lignocelulózových materiálov najma krájaných a lúpaných dýh.The above-mentioned deficiencies are eliminated or largely reduced by a device for refining lignocellulosic materials, especially sliced and peeled veneers.
Podstata vynálezu spočívá v tom, že zariadenie na zušlachťovanie pozostávajúce z nádrže na zušlechťovací roztok, v ktorej je nosič so zušlechťovaným materiálom, má medzi dnom nádrže a spodnou časťou nosiča teleso s otvormi, ktoré je spojené na jednej straně s prívodnou rúrkou a na druhej straně s kyvným ramenom.SUMMARY OF THE INVENTION The refinement device, comprising a refining solution tank in which the carrier is treated with a refined material, has a body with openings between the bottom of the tank and the lower part of the carrier, which is connected on one side to the lance and on the other with swing arm.
Prívodnou rúrkou sa do telesa privádza plynné médium, ktoré otvormi uniká do zušlachťovacieho roztoku a posobí na spodně časti dýh tak, že ich odděluje od seba.A gaseous medium is fed into the body through the inlet pipe, which escapes through the orifices into the quenching solution and sits at the bottom of the veneer so as to separate them from each other.
Plynné médium postupuje medzi dýhami až nad hladinu zušlíachťujúceho roztoku, pričom odděluje od seba dyhy aj v miestach, kde sa dotýkali.The gaseous medium flows between the veneers up to the surface of the refining solution, separating the veneers from each other even where they touched.
Výhoda tohoto zariadenía podlá· vynálezu je najma v tom, že oddelovanie dýh pósobením plynného média následné umožní preniknutie zušlachťovacieho roztoku aj na miesta, na ktoré by neprenikol, připadne prenikol podstatné neskór ako na ostatně přístupné plochy. Vynález umožňuje zvýšíť rovnoměrností zušlachtenia nielen na povrchu, ale aj do híbky, čím urýchluje proces zušlachťovania.The advantage of this device according to the invention is that the separation of the veneers by the action of the gaseous medium subsequently permits the penetration of the quenching solution to the places to which it would not penetrate or eventually penetrated substantially later than the other accessible areas. The invention makes it possible to increase the uniformity of the treatment not only on the surface but also in the depth, thereby speeding up the processing process.

CS 272 960 Bl roztokom 2, v ktorej je nosič 3 so zušlechťovaným materiálom. Medzi dnom nádrže JL a spodnou časťou nosiča 3 je teleso 4 s otvormi 5. Na obr. 1 sú otvory kruhové a na obr.CS 272 960 B1 solution 2, in which the carrier 3 is a refined material. Between the bottom of the tank 11 and the lower part of the carrier 3 there is a body 4 with openings 5. In FIG. 1 the openings are circular and FIG.
je otvor štrbinový, V konkrétnom prikladnom vyhotovení je teleso vytvořené z 'rúrky a je pokračováním prívodnej rúrky 6. Druhý koniec telesa 4 je spojený s kyvným ramenom 7, ktoré je v hornej časti nádrže 1^ uložené v ložisku .8. Kyvné rameno je prostredníctvom pohonu 9 uvádzané do kyvného pohybu, ktorý zabezpečuje účinné posobenie plynného média unikajúceho z otvorov 5 telesa 4.In a specific exemplary embodiment, the body is formed of a tube and is a continuation of the inlet tube 6. The other end of the body 4 is connected to a rocker arm 7, which is mounted in the upper part of the tank 1 in the bearing 8. The rocker arm is actuated by the actuator 9 in a rocking motion, which ensures effective gassing of the gaseous medium escaping from the openings 5 of the body 4.
