On sinänsä tunnettua kuivata huokoisia putkimaisia kappaleita, kuten onttoja olkilieriöitä tai selluloosasta tehtyjä putkia, lämpökammiossa. Niinpä Fl-patentissä 13 014 on esitetty laite onttojen olkilieriöiden kuivaamiseksi, joka laite käsittää kammion, jossa kiertää kuivausilmaa ja jossa on olkilieriöitä kannattava kalteva taso, jota pitkin lieriöt voivat vieriä oman painonsa vaikutuksesta. Kuivaaminen tapahtuu jaksottaisesti siten, että kammio täytetään olkilieriöillä ja sitä mukaa kun kaltevan 2 634 8 4 tason alapäässä oleva lieriö on kuivunut, se poistetaan ja kaltevan tason yläpäähän syötetään uusi lieriö.It is known per se to dry porous tubular bodies, such as hollow straw cylinders or cells made of cellulose, in a heat chamber. Thus, F1 Patent 13,014 discloses an apparatus for drying hollow straw cylinders, the apparatus comprising a chamber in which drying air circulates and having an inclined plane supporting the straw cylinders, along which the cylinders can roll under their own weight. Drying is carried out periodically by filling the chamber with straw cylinders and, as the cylinder at the lower end of the inclined plane 2 634 8 4 has dried, it is removed and a new cylinder is fed to the upper end of the inclined plane.
US-patenttijulkaisussa 1 322 813 on esitetty jatkuvatoiminen laite kuituputkien kuivaamiseksi. Laite käsittää lämpökammion, jossa on päätön ketjupari, joka liikkuu useissa toistensa yläpuolella olevissa tasoissa vuorotellen vastakkaisiin suuntiin. Ketjuparin väliin on sovitettu teloja, jotka pyörivät kiinteällä alustalla ja vuorostaan pyörittävät kulloinkin kahden telan kannattamaa kuitu-putkea. Toinen päätön ketjupari on sovitettu syöttämään kuivattavia kuituputkia kammioon sekä poistamaan kuivatut putket.U.S. Patent No. 1,322,813 discloses a continuous apparatus for drying fibrous tubes. The device comprises a heat chamber with an endless pair of chains moving in a plurality of superimposed planes alternately in opposite directions. Rollers are arranged between the pair of chains, which rotate on a fixed base and in turn rotate the fiber tube supported by the two rolls in each case. The second endless pair of chains is adapted to feed the fiber tubes to be dried into the chamber and to remove the dried tubes.
Myös muunlaisen tavaran, kuten tuorerehun tai metalliesineiden, kuivaamiseksi tai lämpökäsittelemiseksi on tunnettua kuljettaa tavaraa vuorotellen edestakaisin toistensa yläpuolella sijaitsevia, lämmitettyjä tai lämmittämättömiä tasoja pitkin kammion tai kuilun läpi, samalla kun kuumaa ilmaa puhalletaan kammion tai kuilun läpi. Tällaisia laitteita on esitetty DE-kuulutusjulkaisuissa 1 108 149 ja 1 177 667 sekä US-patenttijulkaisussa 2 451 053.Also for drying or heat treatment of other types of goods, such as fresh feed or metal objects, it is known to transport the goods alternately back and forth along superheated, heated or unheated levels through the chamber or shaft, while hot air is blown through the chamber or shaft. Such devices are disclosed in DE-A-1,108,149 and 1,177,667 and in U.S. Pat. No. 2,451,053.
Tämän keksinnön tarkoituksena on saada aikaan laite etenkin huokoisten lieriöiden ja putkien lämpökäsittelemiseksi, joka laite mahdollistaa putkien tehokkaan lämpökäsittelyn, samalla kun putkiin kohdistuvat mekaaniset rasitukset ovat mahdollisimman pieniä.The object of the present invention is to provide a device for the heat treatment of porous cylinders and pipes in particular, which device enables efficient heat treatment of the pipes while minimizing the mechanical stresses on the pipes.
Keksinnön mukainen laite on tunnettu siitä, että levyt ovat lämmittämättömiä ja lävistettyjä, että sopivimmin sauvaroaiset kolat on sovitettu siten, että levyjen ja sen kohdan, jossa kolat koskettavat putkia, välinen etäisyys on enintään yhtä suuri kuin putkien säde, ja että pohjan alla on useita kaasupolttimia, jotka ovat seinäelementtien kattamat, jolloin seinäelementtien välinen pohja on lävistetty ja sopivimmin ritilän kattama.The device according to the invention is characterized in that the plates are unheated and perforated, that the rod-shaped cavities are preferably arranged so that the distance between the plates and the point where the cavities touch the pipes is at most equal to the pipe radius and that there are several gas burners under the base. , which are covered by wall elements, the base between the wall elements being perforated and preferably covered by a grating.
Keksinnön mukaista laitetta voidaan soveltaa monenlaisiin käsittely ihin kuten esimerkiksi kuivatukseen, paahtoon, jäähdytykseen, lämmitykseen, ja sellaisiin toimintoihin kuin esimerkiksi hehkutuksiin, päästöihin ja sentapaisiin. Sitä voidaan käyttää myös kappaleiden pinnan päällystykseen sellaisilla aineilla kuin pinnoitteilla, maaleilla jne., joiden koostumus voi olla hetero- 3 63484 geeninen ja joiden ainesosat joutuvat tehokkaasti sekoitetuiksi niiden liikkeiden aikana joihin kappaleet saatetaan. Sitä voidaan myös käyttää helpottamaan kappaleiden päällystämistä puolijäykillä, taipuisilla tai kokoonvetäytyvillä päällysteillä.The device according to the invention can be applied to a wide range of treatments, such as drying, roasting, cooling, heating, and to functions such as annealing, discharging and the like. It can also be used to coat the surface of bodies with substances such as coatings, paints, etc., which may be heterogeneous in composition and whose ingredients are effectively mixed during the movements to which the bodies are placed. It can also be used to facilitate the coating of pieces with semi-rigid, flexible or shrinkable coatings.
Käsiteltävät kappaleet voivat olla putken muodossa, nimenomaan sylinterimäisen putken muodossa. Ne voivat olla varsinkin kuituisia tuotteita, nimenomaan eristäviä kuituisia kuoria, joissa kuitujen väleihin on levitetty sideainetta, jolloin'kammiossa olevat kaasut saavat aikaan lämpökäsittelyn tuotteiden koko paksuudella, niin että sideaine saadaan polymeroitumaan eli kovettumaan. Nämä tuotteet voivat olla esimerkiksi sellaisia kuituisia eristyskuoria, varsinkin pieniläpimittaisia, jotka on esitetty ranskalaisessa patenttihakemuksessa 74 17232 ja jotka on muodostettu huovasta, johon on hajoitettu sideainetta, ja joiden rakenne on läpäisevä ja käsittää kovetetun ja sileän sisä- ja ulkopinnan.The bodies to be treated may be in the form of a tube, in particular in the form of a cylindrical tube. They can be, in particular, fibrous products, in particular insulating fibrous shells in which a binder is applied between the fibers, whereby the gases in the chamber provide a heat treatment over the entire thickness of the products so that the binder is polymerized. These products can be, for example, fibrous insulating shells, in particular of small diameter, disclosed in French patent application 74 17232, formed of a felt in which a binder has been dispersed, and having a permeable structure comprising a hardened and smooth inner and outer surface.
Muita keksinnön tunnusmerkkejä ja etuja käy ilmi seuraavasta selityksestä, joka koskee erästä keksinnön sovellutusmuotoa, joka esitetään keksintöä rajoittamattomana esimerkkinä.Other features and advantages of the invention will become apparent from the following description of an embodiment of the invention, given by way of non-limiting example.
Selityksen aikana viitataan oheiseen piirustukseen, jossa:During the explanation, reference is made to the accompanying drawing, in which:
Kuvio 1 esittää kammiota pystykuvantona, josta osia on pois murrettu, kuvio 2 on detaljikuvanto kappaleita kammion sisässä kuljettavasta ja vierittävästä laitteesta, kuvio 3 on pituussuuntainen leikkauskuvanto, suuremmassa mittakaavassa, kuvion 1 mukaisen kammion kuljetuslaitteesta, kuviot 4 ja 5 ovat pituussuuntaisia osaleikkauskuvantoja kahdesta käsiteltävien kappaleiden kuljetuslaitteen sovellutusmuodosta.Fig. 1 shows the chamber in a vertical view with parts broken away, Fig. 2 is a detailed view of the device for transporting and scrolling pieces inside the chamber, Fig. 3 is a longitudinal sectional view, on a larger scale, of the chamber transport device embodiment.
Esitetty esimerkki koskee laitteen sovellutusta kuituisiin eristys-kuoriin A, jotka on muodostettu huovasta, johon on hajoitettu sideainetta, varsinkin sitä tyyppiä, joka on selitetty edellä mainitussa ranskalaisessa patenttihakemuksessa. Tämän laitteen tarkoituksena on suorittaa täydellinen ja yhdenmukainen kuorten paahto saaden aikaan sideaineen polymeroitumisen eli kovettumisen.The example shown relates to the application of the device to fibrous insulating shells A formed of a felt in which a binder has been dispersed, in particular of the type described in the above-mentioned French patent application. The purpose of this device is to perform a complete and uniform roasting of the shells, causing the binder to polymerize, i.e. cure.
Paahdon aikana kammiossa eli uunissa kuoria kuljetetaan pakotta niin, että vältetään ulkokerrosten delaminoituminen ja ulkomuotoa huonontavien pintavikojen muodostuminen. Toisaalta kuoret uunissa viipy- 4 6 3 4 8 4 misensä aikana pysytetään täysin pitkin pituuttaan, niin että ne suorittavat täydellisiä kierroksia keskiviivansa ympäri yhdenmukaistaen paahdon.During roasting, in the chamber or oven, the shells are forcibly transported so as to avoid delamination of the outer layers and the formation of surface defects which degrade the appearance. On the other hand, during their residence in the oven, the shells are kept 4 6 3 4 8 4 completely along their length so that they make perfect revolutions around their center line, harmonizing the roasting.
Kuoret A tuodaan perättäin oven 1 eteen, jota liikuttaa voimalaite 2, joka pysäyttää jokaisen kuoren ennen sen sisään pääsyä. Tämän oven avautuminen on ajoitettu ja rajoitettu uunin lämpöhäviöiden pienentämiseksi.The shells A are successively brought in front of the door 1, which is moved by a power device 2, which stops each shell before entering it. The opening of this door is timed and limited to reduce heat loss in the oven.
Kuorten uunissa viipymisajan pidentämiseksi samalla rajoittaen uunin pituutta, uuni käsittää useita päällettäisiä tasoja, joiden lukumäärä esitetyssä esimerkissä on viisi.In order to prolong the residence time of the shells in the oven while limiting the length of the oven, the oven comprises several coated levels, the number of which in the example shown is five.
Jokaisen näistä tasoista muodostaa rei'itetty laatta 3, yhtenä tai useampana osana, jonka päällä kuoret A saatetaan vierimään kuljettamalla niitä tankojen 4 avulla, jotka kulkevat jatkuvassa siirty-mäliikkeessä. Tätä varten on olemassa ketjut 5 mainittuihin tankoihin kiinnitettyinä. Keksinnön mukainen sovitus on sellainen, että kukin näistä päättömistä ketjuista 5 suorittaa yläjuoksullaan siirtämisen yhteen suuntaan ja sitten alajuoksullaan toiseen suntaan, kahdessa toisiaan seuraavassa reikälaattakerroksessa 3.Each of these planes is formed by a perforated plate 3, in one or more parts, on which the shells A are made to roll by conveying them by means of rods 4 running in a continuous displacement. To this end, there are chains 5 attached to said rods. The arrangement according to the invention is such that each of these endless chains 5 performs at its upstream transfer in one direction and then at its downstream in the other direction, in two successive perforated plate layers 3.
Kyseessä olevassa esimerkissä on kolme ketjua 5, jotka on varustettu tangoilla 4, viiden päällettäisen tason aikaansaamiseksi. Ketjuja kuljettaa nopeuden säädöllä varustettu moottori pääteketjupyöriin 6 loraistuvan ketjun välityksellä.In the example in question, there are three chains 5 provided with rods 4 to provide five overlapping planes. The chains are driven by a speed-controlled motor on the end sprockets 6 via a sling chain.
Kuoret A lasketaan revitetyille laatoille 3 kahden perättäisen tangon 4 väliin. Päättömän ketjun 5 siirtyminen aiheuttaa tankojen 4 etenemisen. Jokaista kuorta A työntää se tanko, joka on välittömästi sen ylävirran puolella, ja se etenee vierien kannatuslaattaa 3 myöten. Kyseessä olevan rei'itetyn laatan pään 9 ja viimeisen tangon välissä ketjupyörän 6 edessä on vapaa tila 7, jonka kautta kuori A pääsee painovoiman vaikutuksesta siirtymään alemmalle tasolle.The shells A are lowered onto the torn plates 3 between two successive bars 4. The displacement of the endless chain 5 causes the rods 4 to advance. Each shell A is pushed by the bar immediately upstream of it and advances along the rolling support plate 3. Between the end 9 of the perforated plate in question and the last rod, there is a free space 7 in front of the sprocket 6, through which the shell A can move to a lower level due to gravity.
Tällä tasolla tangot kulkevat vastakkaiseen suuntaan, koska niitä kuljettaa päättömän ketjun paluujuoksu. Tästä seuraa, että kokillit joutuvat samoissa olosuhteissa uudelleen kulkemaan vaakasuorassa vastakkaiseen suuntaan siihen nähden, mihin ne ovat kulkeneet lähinnä ylemmällä tasolla. Kuoret poistuvat vihdoin alimmalta tasolta 8 vierien kaltevaa tasoa 10 myöten.At this level, the rods travel in the opposite direction because they are carried by the return run of the endless chain. It follows that, under the same conditions, the molds have to re-run horizontally in the opposite direction to where they have traveled mainly at the upper level. The shells finally leave the lowest level 8, rolling down to a sloping level of 10.

Uunin lämmitys suoritetaan kaasupolttimilla 12, jotka on sijoitettu uunin lattialle 13 ja joiden yläpuolelle on sovitettu pienet hapettumatonta metallia olevat holvit 14 paikallisten ylikuumentumisten välttämiseksi uunin alatasolla. Kuuman, uunin koko korkeudelle nousevan ilman jakautuminen tasaisesti suoritetaan ohuen rei'itetyn levyn 15 avulla, joka on yhdensuuntainen holvien 14 yläosan kanssa ja sijaitsee jonkin matkan päässä näistä.The heating of the furnace is carried out by gas burners 12 placed on the furnace floor 13 and above which small non-oxidizing metal vaults 14 are arranged to avoid local overheating on the lower level of the furnace. The even distribution of the hot air rising to the entire height of the furnace is effected by means of a thin perforated plate 15 parallel to the top of the vaults 14 and located at some distance from them.
Kun ilma on kulkenut läpi, kosketuksessa kaikkien kuorten kanssa, se poistuu savutorven 16 kautta.Once the air has passed through, in contact with all the shells, it exits through the flue 16.
Edellä selitetty ja piirustuksessa esitetty esimerkki koskee tapausta, jossa käsiteltäviä kappaleita A kannattavat laatat ovat vaakasuorassa asennossa.The example described above and shown in the drawing relates to the case where the plates supporting the pieces A to be treated are in a horizontal position.
Kuvioiden 4 ja 5 mukaisessa sovellutusmuodossa nämä laatat ovat kaltevat vaakatasoon nähden.In the embodiment according to Figures 4 and 5, these plates are inclined with respect to the horizontal.
Kuvion 4 mukaan laatan 3 kaltevuus on nouseva kappaleiden A kulkusuuntaan päin, jolloin tangot 4,joiden kanssa kappaleet ovat kosketuksessa, kuljettavat näitä.According to Fig. 4, the inclination of the plate 3 is increasing towards the direction of travel of the pieces A, whereby the rods 4 with which the pieces are in contact carry them.
Tällä sovellutusmuodolla saadaan aikaan se, että kappaleet pyörivät säännöllisesti siinäkin tapauksessa, että kappaleiden pyörin-nän muoto on epätäydellinen.This embodiment ensures that the bodies rotate regularly even if the shape of the rotation of the bodies is incomplete.
Kuvion 5 mukaisessa sovellutusmuodossa laatan 3 kaltevuus on laskeva kappaleiden A kulkusuuntaan päin. Kappaleita kuljettaa painovoima, ja tässä tapauksessa tangot 4 säännöstelevät kappaleiden liikettä. Paitsi sitä etua, mistä edellä on mainittu kuvion 4 yhteydessä, laatan 3 tällainen sovitus edistää kappaleista A niiden kulkiessa käsittelykammlossa mahdollisesti irronneiden aineshiukkasten poistoa.In the embodiment according to Figure 5, the inclination of the plate 3 is decreasing in the direction of travel of the pieces A. The pieces are carried by gravity, and in this case the rods 4 regulate the movement of the pieces. In addition to the advantage mentioned above in connection with Fig. 4, such an arrangement of the plate 3 facilitates the removal of any particles which may have come off the pieces A as they pass in the treatment comb.
