Description
Ovaj izum se odnosi na one uređaje za lijepljenje koji se upotrebljavaju u postrojenjima za proizvodnju iverica da bi rasporedili dovoljnu količinu tekućeg ljepila u masi čestica drva ili ivera kako bi omogućili toj masi da se pretvori u ploče iverice sljedećim postupcima. This invention relates to those gluing devices used in chipboard manufacturing plants to distribute a sufficient amount of liquid adhesive in a mass of wood particles or chips to enable that mass to be converted into particleboard by the following processes.
Tradicionalni uređaji za lijepljenje obuhvaćaju uobičajenu cilindričnu komoru za miješanje s pretežno horizontalnom osi, na čijem jednom kraju ulaze zbog gravitacije čestice drva željenih veličina u odgovarajućim odmjerenim količinama. Unaprijed određena količina tekućeg ljepila, koje se obrađuje na temperaturi, također se uvodi u komoru, obično raspršivanjem. Uređaj za lijepljenje obuhvaća također uređaj za njihovo miješanje, više ili manje intenzivno, i za prenošenje dobivene mase, nakon unaprijed određenog vremena, do izlaznog otvora kroz koji ona kasnije, nazvana nadalje mješavina, koja je načinjena od čestica drveta namočenih ljepilom, listića. Traditional gluing devices include a common cylindrical mixing chamber with a predominantly horizontal axis, at one end of which wood particles of the desired sizes enter due to gravity in appropriately measured quantities. A predetermined amount of heat-cured liquid adhesive is also introduced into the chamber, usually by spraying. The gluing device also includes a device for mixing them, more or less intensively, and for transferring the obtained mass, after a predetermined time, to the outlet through which it later, called the mixture, which is made of wood particles soaked in glue, leaves.
Za daljnju upotrebu smjese ljepilo treba biti raspoređeno jednoliko po površini svake čestice, primjenom na površinu svake čestice količine ljepila koja je proporcionalna njenoj površini. Ipak je ustanovljeno da se u poznatim uređajima za lijepljenje to ne događa u optimalnom stupnju. Obzirom na to, u konačnoj smjesi ljepilo namoči čestice manjih veličina većom jednolikošću. U svakoj šarži čestica drveta, čak i ako je vrlo strogo kontrolirana raspodjela veličina čestica znatna je raznolikost veličina čestica, odatle raspodjela ljepila po površini čestica nije u skladu s rečenim optimumom. For further use of the mixture, the glue should be distributed uniformly over the surface of each particle, applying to the surface of each particle an amount of glue that is proportional to its surface. However, it has been found that in known gluing devices this does not occur to an optimal degree. Due to this, in the final mixture, the glue soaks the particles of smaller sizes with greater uniformity. In each batch of wood particles, even if the particle size distribution is very strictly controlled, there is a considerable diversity of particle sizes, hence the distribution of the glue on the surface of the particles is not in accordance with the said optimum.
Stručnjacima u tom području je dobro poznato da tradicionalni uređaji za lijepljenje nude dosta nisku razinu komore za miješanje, koja ne prelazi 40 % volumena komore, s vremenom zadržavanja čestica drveta u komori za miješanje koje varira od 20 do 30 sekundi, ovisno o kapacitetu. It is well known to those skilled in the art that traditional gluing devices offer a fairly low mixing chamber level, not exceeding 40% of the chamber volume, with a residence time of the wood particles in the mixing chamber varying from 20 to 30 seconds, depending on the capacity.
Da bi se dobila poboljšana raspodjela ljepila već je bilo predloženo da se poveća vrijeme miješanja čestica drveta s ljepilom, i da se poveća intenzitet miješanja. Jedan način povećanja intenzitete miješanja je povećanje brzine elementa za miješanje. U nekim poznatim uređajima za miješanje obodna brzina dijela za miješanje može u stvari dostići 14 - 17 m/s, ali s rezultatom da čestice drveta pucaju, s konačnom promjenom u rasporedu njihovih veličina, što više nije optimalno. Velika brzina miješanja također dovodi do porasta temperature miješanja s posljedicom polimerizacije ljepila, koje djelomično gubi svoju učinkovitost. In order to obtain an improved distribution of the glue, it has already been proposed to increase the mixing time of the wood particles with the glue, and to increase the mixing intensity. One way to increase the mixing intensity is to increase the speed of the mixing element. In some known mixing devices, the peripheral speed of the mixing part can in fact reach 14 - 17 m/s, but with the result that the wood particles crack, with a final change in their size distribution, which is no longer optimal. A high mixing speed also leads to an increase in the mixing temperature with the consequence of polymerization of the glue, which partially loses its effectiveness.
Drugo rješenje koje se koristi za poboljšanje raspodjele ljepila je zaprečavanje istjecanja smjese iz komore za miješanje uređaja za lijepljenje, koje je jednakovrijedno produženju vremena zadržavanja čestica drva u komori, s posljedicom produženja miješanja s ljepilom. Ovo rješenje ima za cilj povećanje punjenja komore za miješanje, ali samo u okolini njenih izlaznih vratiju. Namještanje vratiju se označava u postocima, pri čemu 0 % odgovara potpuno otvorenim vratima, a 100 % potpuno zatvorenim. Ipak suviše visok postotak zatvorenosti vratiju ne može se koristiti, jer to u velikoj mjeri povećava temperaturu mješavine, s posljedicom polimerizacije ljepila. Another solution used to improve the distribution of the glue is to prevent the mixture from flowing out of the mixing chamber of the gluing device, which is equivalent to prolonging the residence time of the wood particles in the chamber, with the consequence of prolonging the mixing with the glue. This solution aims to increase the filling of the mixing chamber, but only in the vicinity of its outlet ports. The door adjustment is indicated in percentages, where 0% corresponds to a fully open door and 100% to a fully closed door. However, too high a percentage of closed doors cannot be used, because it increases the temperature of the mixture to a great extent, with the consequence of polymerization of the glue.
Neki drugi postupak već korišten za produženje vremena miješanja je da se iza prvog uređaja za lijepljenje ugradi drugi uređaj za lijepljenje s jedinom svrhom ponovnog miješanja smjese nakon prvog miješanja. Ovo rješenje dovodi do znatnog poboljšanja u raspodjeli ljepila, ali uz znatno povećanje troškova postrojenja i troškova pogona, uz dodatno povećanje ukupne veličine postrojenja. Another method already used to extend the mixing time is to install a second sizing device after the first sizing device for the sole purpose of re-mixing the mixture after the first mixing. This solution leads to a significant improvement in adhesive distribution, but at a significant increase in plant and operating costs, with an additional increase in overall plant size.
Kako je već navedeno, svi poznati uređaji za lijepljenje imaju stupanj ispunjenosti komore za miješanje koji dostiže maksimum od 40 %, odatle slijedi da komora za miješanje mora imati znatno veći volumen nego je efektivno ispunjena mješavinom. To ima za posljedicu značajne dimenzije koje treba uzeti u obzir pri projektiranju postrojenja. As already stated, all known gluing devices have a degree of filling of the mixing chamber that reaches a maximum of 40%, from which it follows that the mixing chamber must have a significantly larger volume than is effectively filled with the mixture. This results in significant dimensions that need to be taken into account when designing the plant.
Predmet ovog izuma je izbjegavanje naprijed opisanih nedostataka poznatih uređaja za lijepljenje. The object of the present invention is to avoid the previously described disadvantages of known gluing devices.
Sljedeća namjera je dobiti uređaj za lijepljenje koji ima jednostavnu konstrukciju, pouzdan rad i lako održavanje i čišćenje. The next intention is to obtain a gluing device that has a simple construction, reliable operation and easy maintenance and cleaning.
Navedene namjere su postignute uređajem za miješanje iz izuma, koji obuhvaća jednu cilindričnu komoru za miješanje u kojoj se nalaze jedan otvor za punjenje, jedan izlazni otvor i jedan element za miješanje, karakteristični po tome da je komora za miješanje postavljena vertikalno, otvor za punjenje se nalazi u donjem dijelu komore za miješanje, a izlazni otvor (36) se nalazi u gornjem dijelu komore za miješanje (12), sredstva za punjenje čestica drva pune komoru za miješanje preko otvora za punjenje. The stated intentions are achieved by the mixing device of the invention, which includes one cylindrical mixing chamber in which there is one filling opening, one exit opening and one mixing element, characterized by the fact that the mixing chamber is placed vertically, the filling opening is located in the lower part of the mixing chamber, and the exit opening (36) is located in the upper part of the mixing chamber (12), the wood particle fillers fill the mixing chamber through the filling opening.
Poželjno je da sredstva za punjenje komore za miješanje česticama drva obuhvaćaju napojni vijak. Preferably, the means for filling the mixing chamber with wood particles comprise a feed screw.
Da bi se olakšalo kretanje prema gore kroz komoru za miješanje čestica drva koje su unijete kroz otvor za punjenje, predviđen je vertikalni vijak u donjem dijelu komore za miješanje. To facilitate the upward movement through the mixing chamber of the wood particles introduced through the filling opening, a vertical screw is provided in the lower part of the mixing chamber.
Izum će biti jasniji iz njegove slijedeće materijalizacije. U ovom opisu poziva se na pridružene nacrte, na kojima pojedine slike prikazuju shematski vertikalni presjek kroz izumljeni uređaj za lijepljenje. The invention will be clearer from its subsequent materialization. In this description, reference is made to the accompanying drawings, in which certain figures show a schematic vertical section through the inventive gluing device.
Kao što se može vidjeti iz slike, uređaj za lijepljenje 10 ima vertikalnu cilindričnu komoru 12 načinjenu od dva koncentrična cilindrična čelična plašta 14 i 16, smještena odvojeno da čine međuprostor 18, čija namjena će biti kasnije objašnjena. Cilindrična komora 12 ima otvor za punjenje 20 uz kojeg se nalazi jedan kraj motorom pogonjenog vijka za punjenje 22 zatvorenog u odgovarajuće cilindrično kućište 24. Kao što se može vidjeti vijak 22 je u stvari horizontalan, iako to nije bitno. Na vrhu krajnjeg završetka kućišta 24 nalazi se otvor 26 kroz koji se čestice drva pune silom gravitacije i ove se dalje guraju u cilindričnu komoru 12 djelovanjem vijka 22. As can be seen from the figure, the bonding device 10 has a vertical cylindrical chamber 12 made of two concentric cylindrical steel shells 14 and 16, placed separately to form an intermediate space 18, the purpose of which will be explained later. The cylindrical chamber 12 has a charging port 20 against which is located one end of a motor-driven charging screw 22 enclosed in a corresponding cylindrical housing 24. As can be seen the screw 22 is in fact horizontal, although this is not essential. At the top of the end of the casing 24 there is an opening 26 through which the wood particles are filled by the force of gravity and these are further pushed into the cylindrical chamber 12 by the action of the screw 22.
Kao što se može vidjeti na slici, donji dio cilindrične komore 12 ima vertikalni motorom pogonjen vijak 28 oblika krnjeg stošca, koaksijalan s komorom 12, čija rotacija tjera prema gore čestice drva u komoru 12 djelovanjem vijka za punjenje 22. As can be seen in the figure, the lower part of the cylindrical chamber 12 has a vertical motor-driven screw 28 of the shape of a truncated cone, coaxial with the chamber 12, the rotation of which forces the wood particles upwards into the chamber 12 by the action of the loading screw 22.
Iznad vertikalnog vijka 28 oblika krnjega stošca nalazi se uređaj za miješanje 30 koji se sastoji od motorom pogonjene koaksijalne osovine 32 iz koje se radijalno pružaju krakovi za miješanje 34, i koji su naznačeni u slikama vrlo shematski, a standardnog su oblika. Krakovi za miješanje mogu imati različite oblike, ovisno o visini na kojoj su smješteni. Kao u specifičnom slučaju prikazanom na slici, uređaj za miješanje 30 može biti kruto spojen na vertikalni vijak 28 (tako da je oboje pogonjeno jednim i istim motorom), tako da je ovaj uklinjen na osovinu 32, koja je učvršćena na svojim krajevima držačima 42 i 43 tako da može rotirati. Međutim jasno je da osovina elementa za miješanje i vertikalni vijak mogu biti pogonjeni neovisno, čak i različitim brzinama, svaki svojom osovinom. Treba također napomenuti da vertikalni vijak može imati drukčiji oblik nego krnjeg stošca (na primjer cilindričan oblik). Above the truncated cone-shaped vertical screw 28 is a mixing device 30 consisting of a motor-driven coaxial shaft 32 from which radially extend mixing arms 34, which are shown in the figures very schematically and are of a standard shape. The mixing arms can have different shapes, depending on the height at which they are placed. As in the specific case shown in the figure, the mixing device 30 can be rigidly connected to the vertical screw 28 (so that both are driven by one and the same motor), so that the latter is wedged on the shaft 32, which is fixed at its ends by holders 42 and 43 so that it can rotate. However, it is clear that the shaft of the mixing element and the vertical screw can be driven independently, even at different speeds, each by its own shaft. It should also be noted that a vertical screw can have a different shape than a truncated cone (for example, a cylindrical shape).
Kao što se može vidjeti na slici, predviđen je izlazni otvor 36 blizu vrha cilindrične komore 12. U prikazanom primjeru, radijalne "lopatice" 46 predviđene su na osovini 32 da bi olakšale pražnjenje mješavine iz komore za miješanje 12 kroz izlazni otvor 36 prelijevanjem. As can be seen in the figure, an outlet port 36 is provided near the top of the cylindrical chamber 12. In the example shown, radial "blades" 46 are provided on the shaft 32 to facilitate discharge of the mixture from the mixing chamber 12 through the outlet port 36 by overflow.
Bočne stijene komore 12 i element za miješanje 30 su hlađeni na uobičajen način da bi se spriječilo da mješavina, kao rezultat zagrijavanja uzrokovanog miješanjem, dostigne temperaturu koja bi uzrokovala polimerizaciju ljepila, rezultat čega bi bilo brzo onečišćenje onih dijelova stroja za lijepljenje 10, koji dolaze u kontakt s mješavinom. The side walls of the chamber 12 and the mixing element 30 are cooled in a conventional manner to prevent the mixture, as a result of the heating caused by the mixing, from reaching a temperature which would cause the adhesive to polymerize, resulting in rapid contamination of those parts of the gluing machine 10 which come in contact with the mixture.
Zasun 38 koji zatvara odgovarajući otvor nalazi se na dnu kućišta 24 vijka za punjenje 22, u ovom specifičnom slučaju zasun 38 se aktivira konvencionalnim pneumatskim uređajem općenito kao 40 u slici. A latch 38 which closes the corresponding opening is located at the bottom of the housing 24 of the charging screw 22, in this particular case the latch 38 is actuated by a conventional pneumatic device generally as 40 in the figure.
Ljepilo se uštrcava u unutrašnjost komore za miješanje 12 na različitim točkama raspoređenim na raznim visinama (kao što je shematski naznačeno na slici, na kojoj su vidljive tri mlaznice 48 smještene na raznim visinama, opskrbljivane tekućim ljepilom) sa zadaćom da se namoče čestice drva ljepilom na postepenim stupnjevima. Kao što je stručnjacima poznato, uštrcavanje ljepila u postepenim stupnjevima omogućava da se dobije tako zvani efekt "oblaganja površine" čestice, kojim se reducira upijanje ljepila u česticu, s posljedicom smanjenja potrebne količine ljepila. The glue is injected into the interior of the mixing chamber 12 at different points distributed at various heights (as schematically indicated in the figure, in which three nozzles 48 located at various heights are visible, supplied with liquid glue) with the task of soaking the wood particles with glue on by gradual degrees. As is known to experts, injecting the glue in gradual stages allows to obtain the so-called effect of "coating the surface" of the particle, which reduces the absorption of the glue into the particle, with the consequence of reducing the required amount of glue.
Rad gore opisanog uređaja za lijepljenje opisan je kratko u daljem tekstu, a stručnjaku bi trebao biti jasan iz već prije navedenog. The operation of the above-described gluing device is briefly described below, and should be clear to an expert from the above.
Kao što je rečeno, masa čestica drva gravitacijom ulazi kroz otvor 26 predviđen na kućištu 24 vijka 22. Rotiranjem ovog posljednjeg čestice drva se postepeno tjeraju prema komori za miješanje 12, pa kroz otvor za punjenje 20 i u dno komore 12, gdje nailaze na vertikalni vijak 28, koji ih rotirajući tjera prema gore. Za vrijeme njihovog kretanja prema gore čestice drva se susreću na postepenim stupnjevima s mlazevima ljepila koje izlazi iz mlaznica 48, i istovremeno se miješaju uređajem za miješanje 30. Ukupan učinak zbog djelovanja uređaja za miješanje 30 i vertikalnog miješanja omogućava dobivanje optimalnih rezultata, tj. vrlo jednoliko premazivanje ljepilom površine čestica drva. As said, the mass of wood particles enters by gravity through the opening 26 provided on the housing 24 of the screw 22. By rotating the latter, the wood particles are gradually pushed towards the mixing chamber 12, then through the filling opening 20 and into the bottom of the chamber 12, where they meet the vertical screw 28, which rotates and pushes them upwards. During their upward movement, the wood particles meet at gradual stages with the jets of glue coming out of the nozzles 48, and at the same time they are mixed by the mixing device 30. The overall effect due to the action of the mixing device 30 and the vertical mixing makes it possible to obtain optimal results, i.e. very uniform coating of the surface of wood particles with glue.
Mješavina čestica drva i ljepila konačno odlazi kroz izlazni otvor 36 prelijevanjem koje je pomognuto djelovanjem lopatica 46. The mixture of wood particles and glue finally leaves through the outlet opening 36 by overflowing, which is assisted by the action of the vanes 46.
Uređaj za lijepljenje se hladi cirkuliranjem rashladnog fluida, kao voda, kroz međuprostor 18 između cilindričnih plašteva 14 i 16. Šupljine (nisu prikazane) su također predviđene u uređaju za miješanje 30 radi cirkuliranja rashladnog medija. The bonding device is cooled by circulating a cooling fluid, such as water, through the interspace 18 between the cylindrical shells 14 and 16. Cavities (not shown) are also provided in the mixing device 30 to circulate the cooling medium.
Važno je napomenuti da se takvim uređajem za lijepljenje može postići 60 - 70 % punjenja komore za miješanje 12, što je znatno više nego kod poznatih uređaja za lijepljenje (najviše 40 %). Ovakav stupanj punjenja omogućava dobivanje dobrog miješanja s malom brzinom okretanja uređaja za miješanje. Posebno, obodna brzina uređaja za miješanje 30 može biti održavana na oko 7 - 10 m/s, što omogućava da čestice drva održavaju prostornu raspodjelu, dok je istodobno nedvojbeno vrijeme održavanje mješavine čestica/ljepilo unutar komore za miješanje 12, više za red veličine od 60 - 70 sekundi, u usporedbi s poznatim uređajima za lijepljenje. Tako visoko vrijeme zadržavanje biti će kontraproduktivno u tradicionalnim uređajima za lijepljenje u kojima je brzina miješanja znatno veća (14 - 17 m/s). Temperatura čestice zapravo raste i posljedica je predpolimerizacija ljepila. It is important to note that 60-70% filling of the mixing chamber 12 can be achieved with such a gluing device, which is significantly more than with known gluing devices (maximum 40%). This degree of filling enables good mixing to be obtained with a low rotation speed of the mixing device. In particular, the peripheral speed of the mixing device 30 can be maintained at about 7 - 10 m/s, which allows the wood particles to maintain a spatial distribution, while at the same time undoubtedly maintaining the particle/glue mixture inside the mixing chamber 12 is an order of magnitude higher than 60 - 70 seconds, compared to known gluing devices. Such a high retention time will be counterproductive in traditional gluing devices where the mixing speed is much higher (14 - 17 m/s). The temperature of the particle actually increases and is a consequence of the prepolymerization of the glue.
Iz gore rečenog biti će jasno da izumljeni uređaj za lijepljenje ima dosta jednostavnu strukturu, i da ga je stoga jednostavno izraditi. Kako se ne pojavljuje onečišćavanje na onim dijelovima koji dolaze u dodir s mješavinom čestica drva i ljepila, održavanje i čišćenje je mnogo jednostavnije nego kod poznatih uređaja za lijepljenje. Dodatno, kako je zahtjevana instalirana snaga manja, takav uređaj za lijepljenje troši znatno manje energije nego poznati uređaji za lijepljenje, uz to mu je znatno manja ukupna veličina. It will be clear from the above that the invented gluing device has a fairly simple structure, and that it is therefore easy to manufacture. As contamination does not appear on those parts that come into contact with the mixture of wood particles and glue, maintenance and cleaning is much simpler than with known gluing devices. Additionally, as the required installed power is lower, such a gluing device consumes significantly less energy than known gluing devices, and its overall size is significantly smaller.
Daljnja prednost izumljenog uređaja za lijepljenje je ta da se povećava vertikalno i ima otvor za izlaz mješavine na vrhu (tj. na znatno većoj visini nego kod poznatih uređaja za lijepljenje), mogu biti eliminirani neki mehanički prijenosnici (nisu prikazani) potrebni za prijenos mješavine od izlaza 36 uređaja za lijepljenje do stroja za oblikovanje ploča (nije prikazan), i ovaj posljednji može biti smješten u odgovarajućem postrojenju na znatno višoj razini nego kod poznatih uređaja za lijepljenje. Skraćivanje staze prijenosnog konvejera skraćuje se vrijeme prijenosa i time tendencija da polimerizira ljepilo sadržano u mješavini. A further advantage of the inventive gluing device is that since it increases vertically and has a mixture exit opening at the top (i.e. at a significantly higher height than known gluing devices), some mechanical conveyors (not shown) required to transfer the mixture from output 36 of the gluing device to the plate forming machine (not shown), and the latter can be located in the corresponding plant at a much higher level than in known gluing devices. Shortening the path of the transfer conveyor shortens the transfer time and thus the tendency to polymerize the adhesive contained in the mixture.
Kada uređaj za lijepljenje 10 treba biti ispražnjen u svrhu održavanja ili zbog duljeg zaustavljanja, to se može postići vrlo lako promjenom smjera vrtnje vertikalnog vijka 28 i horizontalnog vijka 22 i otvaranjem zasuna 38, kroz koji istječe materijal iz uređaja koji se nalazi u komori za miješanje 12. When the gluing device 10 needs to be emptied for the purpose of maintenance or due to a longer stop, this can be achieved very easily by changing the direction of rotation of the vertical screw 28 and the horizontal screw 22 and opening the latch 38, through which the material flows out of the device located in the mixing chamber 12.
