Abstract

Medzi dnom nádrže a spodnou časóou nosiča je teleao na přívod plynného mé dia, ktoré je spojené a prfvodnou^rúrkou. Prívodná rúrka je otočné uložená v ložiskách a v hornej časti spojená s pohonom a s prívodnou hadicou, ktorou prúdi zo zásobníka plynné médium oez. privodnú rúrku do telesa. Pohon zabezpečuje výkyvný pohyb telesa okolo osi totoznej s osou prívodnej rúrky v jej vertikálnej časti.Between the bottom of the tank and the lower part of the carrier there is a body for supplying the gaseous medium, which is connected to a supply pipe. The supply pipe is rotatably mounted in bearings and in the upper part is connected to the drive and to a supply hose, through which the gaseous medium flows from the reservoir through the supply pipe to the body. The drive ensures the swinging movement of the body around an axis identical to the axis of the supply pipe in its vertical part.

Vynález sa týká zariadení na zuéíachtovanie lignocelulózových materiélov, najmakrájených a ldpanýeh dýh.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for utilizing lignocellulosic materials, vermicelli and veneers.

Doteraz známe zariadenia na zuSÍachtovanie dyhovacích materiálov pozostévajú zva-čSa z nádrže a otvorami na přívod a odvod zužíaehtovacleho roztoku, čerpadla a výmeníkatepla, ktorým je zabezpečené ohrievanie počeš zuSÍachtovania.Up-to-date vapor deposition devices are known to consist of the tank and the inlet and outlet openings, the pump, and the heat exchanger to heat up.

Ti.eto zariadenia sa najčastejSie využívajd na farbenie dyhovacích materiálov, lehnízký výkon je zapříčiněný najma tým, že praoovný objem nádrže može byt zaplněný iba ma-lým množstvom dýh, ktoré muela byť uložené a dodržením značného volného prleetoru medziplochami jednotlivých dýh. Na doelahnutie rovnoměrného prefarbenia připadá v priemere na1 mm hrůbky dýh medzera 3-6 mm. Nízký stupeň zaplnenia týchto zariadení má za následok poměrně málú kapacitu a vy-soká spotřebu vody a farbiva. Používanie týchto Zariadení na homogenné farbenie dýh jespojené so značnými nárokmi na čistenie odpadových vod a je náročné aj na zastavená plo-chu.These devices are most often used for dyeing veneer materials, lightweight performance is caused mainly by the fact that the volume of the tank can only be filled with a small amount of veneer, which is stored and a considerable free space between the veneer surfaces. A veneer gap of 3-6 mm is found per 1 mm of ridge in order to flatten even color. The low degree of filling of these devices results in relatively low capacity and high water and dye consumption. The use of these devices for homogeneous veneer dyeing, combined with considerable demands for wastewater treatment, is also demanding on the built-up area.

Prl vySSích stupnoch zaplnenia farbiacich nádrží dýhami dochádza k nerovnoměrnémuprefarbenlu materiélov hlavně na stykových miestach medzi jednotlivými dýhami a tiež namiestach, kde sa dyhy dotýkajá ostatných častí zariadenia, alebo diStančných materiálovna oddelenle dýh.Due to the higher filling levels of the veneer staining tanks, the material is unevenly stained mainly at the contact points between the veneers, as well as the veneers where the veneers touch the other parts of the device or the separate material veneer.

Sd známe aj farbiace zariadenia na híbkové farbenie dyhovacích materiálov pozostá-vajdce z farbiacej nádrže a nosiča farbených dýh, do ktorého sa před ponořením do roz-toku naukladajd sdbory dýh. Přívod farbiaceho roztoku do farbiacej nádrže je buď otvormiv dne nádoby, alěbo otvormi rdrok, ktoré sd upevněné v blízkosti stien farbiacej nádoby,v snahe zabezpečil rovnoměrnějSí přísun farbiaceho roztoku na celé plochy jednotlivýchdýh bolo navrhnutých viaoero spSsobov a zariadení, ktoré sd založené buď na principe po-hybu nosiče s dýhami vofarbiacom roztoku, usměrněným prúdenim farbiacej kvapaliny, ale-bo prívodom plynov do farbiaceho roztoku.Also known are dyeing devices for the dyeing of veneer materials consisting of a dyeing tank and a colored veneer carrier into which a veneer assembly is installed prior to immersion. The supply of dyeing solution to the dyeing tank is either open to the bottom of the container, or via openings through which the dye solution is attached to the walls of the container, viaoero spasses and devices have been designed to provide a more uniform supply of dyeing solution over the entire surface of the container. - deflecting the carrier with veneers of the coloring solution, directing the flow of the coloring liquid, or supplying gases to the coloring solution.

Nevýhodou popisovaných zariadení na zabezpečenie rovnoměrnějSieho prefarbenia je buďznačná výrobná náročnost, malá účinnost, alebo nemožnost adaptovania do už vyrobených za-riadení.The disadvantage of the described devices to ensure a more uniform coloring is either a significant manufacturing effort, low efficiency, or the inability to adapt to already manufactured devices.

Uvedené nedostatky odstraňuje, připadne do značnéj miery znižuje zuSÍachtovaoie zn-riadenia na zuSÍachtovanie lignocelulózových materiálov najma krájených a ldpanýeh dýh.The above-mentioned drawbacks are eliminated, possibly to a considerable extent, by the improvement of the lignocellulosic materials utilization, especially in the cutting and lining of veneers.

Podstata vynálezu spočívá v tom, že zuSÍachtovacie zariadenie pozostávajdce z ná-drže so zužíachtovaoím roztokem, v ktoréj je nosič so zuSÍaohtovaným materiálom, má me-dzl dnom nádrže a spodnou častou nosiča teleso no přívod plynného média, ktoré je spo-jené s privodnou rdrkou. Privodná rdrka je orientovaná vertikálně a je spojená s poho-nným mechanizmom, ktorý zabezpečuje otočný vratný pohyb prívodnej rdrky a s ňou spoje-ného telesa na přívod plynného média. Os otáčania je zhodná, alebo rovnoběžné s verti-kálnou osou prívodnej. rdrky.The essence of the invention is that the accumulating device consisting of a container with a shrinking solution, in which the carrier with the concentrated material, has a supply of gaseous medium, which is connected to the supplying fluid, between the bottom of the tank and the lower part of the carrier. . The feed shaft is oriented vertically and is coupled to a drive mechanism which provides a reversible reciprocating motion of the feed shaft and the gas medium connected thereto. The axis of rotation is the same or parallel to the vertical inlet axis. rdrky.

Privodnou rdrkou sá do telesa na přívod plynného média privádza plynné médium, kto-ré otvormi' Uniká do zuSÍachtovacieho roztoku. Plynné médium postupuje medzi dýhami ažnad hladinu roztoku, pričóm oddaluje od sebg dýhy v miestach, kde sa dotýkali. Pohybomtelesa sa dosiahne yySSla účinnost ako prl působení bez pohybu výstupných otvorov.A gaseous medium is introduced into the gaseous medium by means of an aqueous medium, which gasses through the openings into the solution. The gaseous medium proceeds between the veneers to the level of the solution, whereby it moves away from the sebg veneer in the places where they touch. Movement is achieved as efficiently as the action of the outlet openings.

Hlavná výhoda zariadenia padla vynálezu je v oddělovaní dýh posobenim plynného mé-dia, ktoré následná umožňuje prenikanie zuSÍachtovacieho roztoku aj na miesta, na ktoréby v známých zariadeniach neprenikol, připadne by prenikol podstatné neskor. ĎalSou vý-hodou je jednoduchost konStřukčného rieženia, bez nárokov na tesnenip otvorov pod hla-dinou zuSÍachtovacieho roztoku, čo bolo hlavným problémem podobných;zariadení. Vynálezumožňuje zvýSit rovnoměrnost zuSÍachtovania nielen na povrchu, ale aj do hlbky materiá-lu a zrýchlit proces zuSÍachtovania.The main advantage of the device of the invention is in separating veneers by providing a gaseous medium which, in turn, permits penetration of the scaling solution even to the places where it does not penetrate in known devices, eventually penetrating substantially later. A further advantage is the simplicity of the crimping, without the need for sealing holes under the level of the solution solution, which was a major problem of similar devices. The invention makes it possible to increase the uniformity of the pickling not only on the surface but also into the material depth and to accelerate the pickling process.
