Prioritet begard frdn den 17 mars 1948 (4nterileas f6renta stater). Priority was given to it on 17 March 1948 (4nterileas United States).

Foreliggande uppfinning avser en anordning vid speciellt skraptransporlorer. The present invention relates to a device in particular for scraper conveyors.

Andamfilet med denna uppfinning hr att framstalla en skraptransportor med forbattrad tatningsanordning for delar av transportorledningen, sa att den kan utsattas for tryck, sasom t. ex. vid in- eller utloppet till ett karl under tryck eller da en transportordel skall sattas under gas- eller vatsketryck, L. ex. angtryck. The spirit fillet of this invention is to produce a scraper conveyor with an improved sealing device for parts of the conveyor line, so that it can be subjected to pressure, such as e.g. at the inlet or outlet of a man under pressure or when a conveyor part is to be put under gas or liquid pressure, L. ex. angtryck.

Ett annat andamal hr att vid sadana skraptransportiirer erna en forbattrad tatningsanordning, som bestar av ett elastiskt material, sasom gummi, och är armerat medelst Mugsgaende stanger, soin forhindra anordningen att pressas ihop under tryck och vilka avenledes, om de dro delvis frilagda i anordningens inre, tjana att styra skraporna, nar dessa dragas igenom anordningen av transportorkedjan eller -kabeln. Another object is that in such scraper conveyors they are an improved sealing device, which consists of an elastic material, such as rubber, and is reinforced by mugs-going rods, so as to prevent the device from being compressed under pressure and which, if pulled, partially exposed in the interior of the device. , serve to guide the scrapers as they are pulled through the device by the conveyor chain or cable.

A-vsikten hr vidare att for dylika skraptransportorer, framstalla en forbattrad tatningsanordning, vilken hr sa konstruerad, att ett uppvarmnings- eller avkylningsmedium kan cirkulera mom anordningens vaggar, varjamte mojlighet forefinnes att utsatta anordningen for tryck, sa att dess vaggar tvingas att giva efter och darigenom bringas till anliggning mot transportorskraporna, nar dessa passera genom anordningen. The further purpose of such scrap conveyors is to provide an improved sealing device which is so constructed that a heating or cooling medium can circulate along the cradles of the device, and there is a possibility of subjecting the device to pressure so that its cradles are forced to yield and thereby being brought into abutment against the conveyor scrapers as they pass through the device.

Ett annat andamal ar att fOr skraptransportorer astadkommaen-forbattrad tatningsanordning, i vilken dess elastiska vaggar aro def ormerbara genom att lata en vatska under tryck passera genom vaggarna och samtidigt utsattas fir inverkan av en strypanordning, varigenom ett mottryck i vaggarna astadkommes, yilket i sin tur astadkommer dessas deformering och darigenom tat anliggning mot transportorskrap orna. Another object is to provide scraper conveyors with an improved sealing device in which its elastic cradles are deformable by allowing a liquid under pressure to pass through the cradles and at the same time being subjected to the action of a throttling device, thereby providing a back pressure in the cradles, which in turn causes their deformation and thereby bears against the conveyor scrapers.

En annan avsikt är att astadkomma en trycktat skraptransportor, av -vilken en viss del är forsedd med de nya tatningsanord ningarna vid motsatta andar, varyid transportorskraporna noggrant Ulla mot trycktatningsanordningens yaggar, pa samma gang som de passa lost in i ledningen mellan dessa anordningar, si att ledningens hire kan fyllas med anga och transportoren anvandas for att transportera fodoamnen, vilka kokas under transporten genom beroring med ângan, varvid de okokta fodoainnena inmatas vid den ena anden av transportoren och uttages vid den andra. Another intention is to provide a pressurized scraper conveyor, a certain part of which is provided with the new sealing devices at opposite spirits, the conveyor scrapers carefully ulla against the yags of the pressure sealing device, at the same time as they fit loosely into the line between these devices, si that the hire of the line can be filled with steam and the conveyor is used to transport the feedstocks, which are boiled during transport by contact with the steam, the uncooked feedstocks being fed at one end of the conveyor and taken out at the other.

Ytterligare ett andamal hr att framstalla en tryektat skraptransportOr, vilken speciellt lampar sig for avliigsnande av material, som flyta pi en vatska i en behallare. Tatningsanordningen hindrar di vatskan att rinnna tillbaka i behallaren under transporten -Lill avtappningsstallet. Transportoren kan eventuellt monteras pa en flottor, som flyter i ett lampligt hOjdlage i behdllaren. Another purpose is to produce a printed scraper conveyor which is particularly suitable for removing material which floats in a liquid in a container. The sealing device prevents the liquid from flowing back into the container during transport - to the draining stable. The conveyor can optionally be mounted on a float, which floats in a suitable height in the container.

Vidare ir avsikten att astadkomma en forbattrad tatningsanordning fir skrap tran-sportorer, varvid elasticiteten hos materialet i vaggarna av anordningen och dess armering anvandes, for alit transportorskraporna skola komma till trycktat anliggning mot anordningens inre vaggar, nar de firm passera darigenom, utan att vatske- eller gastryck behö- ver anvandas sasom yid andra utforingsformer av uppfinningen. Furthermore, the intention is to provide an improved sealing device for scraper conveyors, using the elasticity of the material in the cradles of the device and its reinforcement, otherwise the conveyor scrapers will come into a pressed abutment against the inner cradles of the device when they pass through it, without or gas pressures need to be used as in other embodiments of the invention.

Slutligen utgor dnnu ett foremal med uppfinningen att astadkomma ett fOrfaringssatt fir kokning eller annan varmebehandling av material, sasom fodoamnen, genom att utsatta dem for inverkan av upphettningsmedia, I. ex. anga, under transporten genom transportOrledningen, pa samma gang som transportOrledningens motsatta andar tatas och till- rackligt mellanrum la.mnas mellan skraporna och ledningens inre vaggar fir att lainna rum for uppvarmningsmediet att passera mellan dem och ph sa satt gcnomtranga alla delar av transportorledningens avstangda del, i vilken 2— — kokningen eller uppvarmningsbehandlingen ager rum. Finally, it is still an object of the invention to provide an experimental cooking or other heat treatment of materials, such as foodstuffs, by subjecting them to the action of heating media, e.g. during transport through the transport line, at the same time as the opposite spirits of the transport line are taken and sufficient space is left between the scrapers and the inner walls of the line to allow room for the heating medium to pass between them and thus penetrate all parts of the suspended part of the transport line. , in which the boiling or heating treatment takes place.

Mellan flansarna 18 och 14 befinner sig den ringformiga, ihaliga delen 17. Den tjanar sasom inlopp for avkylnings- eller uppvarnmingsvatskan, vilken infOres frail tillloppsroret 18, som Sr ingangat i oppningen 19. Mellan flansarna 14 och 15 Sr anordnad den rorformiga hylsan 20, vilken i sin tur Sr forsedd med en rorformig, invandig bekladnad 21 av elastiskt deformerbart material, sasom naturligt eller konstgjort gummi. Bekladnaden 21 Sr fOrsedd med en ringformig kammare 22, som Sr forsedd med en rOransats 23 och ett ror 24, vilket leder till nagot tryckmedium, sasom tryckvatska eller tryckluft. Figs. 1 and 2 show a pressure tightening device of a scraper conveyor, generally designated 10, which Sr is intended to be inserted into the Indian conveyor lines 11 and 12 by means of bolts joining the flanges 13 and 14 at one end saint 15 and 16 at the other. Between the flanges 18 and 14 is the annular, hollow part 17. It serves as an inlet for the cooling or heating liquid, which is inserted from the inlet pipe 18, which Sr enters into the opening 19. Between the flanges 14 and 15 Sr arranged the tubular sleeve 20, which in turn Sr provided with a rudder-shaped, internally cladding 21 of elastically deformable material, such as natural or artificial rubber. The cladding 21 is provided with an annular chamber 22, which is provided with a pipe insert 23 and a pipe 24, which leads to some pressure medium, such as pressure water or compressed air.

Den invandiga bekladnaden 21 Sr Sven forsedd med tuber 25, lampligen av kvadratisk form, vilka aro inbaddade i det elastiska materialet samt forenade vid motsatta andar med den ringformiga tilloppsdelen 17 resp. den mindre, ringformiga avloppsdelen 26. Ett avloppsror 27, som Sr ingangat i halet 28 i den ringformiga delen 26, tjanar till att bortfora avkylnings- eller uppvarmningsvatskan, vilken. tillfores tuberna 25 medelst den ringformiga tilloppsdelen 17 och tilloppsroret 18. Den ringformiga avloppsdelen 26 Sr anordnad inom flansen 15 och halles i riktigt lage av densamma. The inner lining 21 Sr Sven is provided with tubes 25, suitably of square shape, which are embedded in the elastic material and united at opposite spirits with the annular inlet part 17 resp. the smaller, annular drain part 26. A drain pipe 27, which Sr is inserted into the tail 28 in the annular part 26, serves to remove the cooling or heating liquid, which. the tubes 25 are supplied by means of the annular inlet part 17 and the inlet pipe 18. The annular drain part 26 Sr is arranged inside the flange 15 and is kept in the correct position thereof.

Den fria passagen 29 inom den elastiska bekladnaden 21 genomlopes av en skraptransportor, generellt betecknad med 30 och av nagon lamplig typ. Den visade skraptransportomen 30 bestar av en kedja 31, som Sr forsedd med parvis anordnade, yttre och inre lankar 32 resp. 33, vilka aro fOrenade med bultar 34. Mellan lankarna 32 och 33 finnas elastiska brickor 35, gjorda av gummiliknande material och avsedda att tata mot nOtande och fratande material, som eljest skulle fororsaka starkt slitage. The free passage 29 within the elastic cladding 21 is traversed by a scraper conveyor, generally designated 30 and of a lamp type. The scraper conveyor 30 shown consists of a chain 31, which Sr is provided with pairs of outer and inner links 32 arranged in pairs, respectively. 33, which are joined by bolts 34. Between the liners 32 and 33 are elastic washers 35, made of rubber-like material and intended to abut against abrasive and abrasive materials, which would otherwise cause strong wear.

PA bultarna 34 finnas Sven oron 36 och 37, som limo forsedda med de St motsatta hall vanda, halvcirkelformiga plattorna 38 resp. 39. Mellan varje par av plattorna 38 och 39 Sr anordnad en skrapa 40, lampligen av gummi eller gummiartat material. Denna skrapenhet 41 halles tillsammans av bultarna 42. For siidant material, som Sr skadligt for naturligt eller konstgjort gummi eller som enfordrar en hogre temperatur, kunna metallskrapor anvandas i stallet for de av gummi gjorda skraporna 40. Under ytterligare andra forhallanden kunna skrapor av plast eller till och med av tra vara mera lampliga, beroende pa omstandigheterna och anvandningen. On the bolts 34 are Sven oron 36 and 37, which are limo fitted with the St opposite hall vanda, semicircular plates 38 resp. 39. Between each pair of plates 38 and 39 Sr arranged a scraper 40, preferably of rubber or rubbery material. This scraper unit 41 is held together by the bolts 42. For solid material, which is harmful to natural or artificial rubber or which requires a higher temperature, metal scrapers can be used instead of the rubber scrapers 40. Under still other conditions, scrapers of plastic or even of wood be more suitable, depending on the circumstances and the use.

Den modifierade tatningsanordningen, som generellt betecknas med 50 och som visas i fig. 3 och 4, liknar i princip den tatningsanordning 10, som Sr visad i fig. 1 och 2, och liknande delar hava darfor samma beteckningar. I fig. 3 Sr emellertid avkylnings- och uppviirmningsanordningen uteliimnad. Det ihaliga, ringformiga tilloppet 17 resp. 26 aro utbytta mot massiva, ringformiga delar 51 resp. 52, och dessa limo antingen fastbultade vid eller pa annat sa.tt fastsatta i de utrymmen, som fOrut voro upptagna av de ihaliga„ ringformiga delarna 17 och 26 i fig. 1 och 2. Den ringformiga kammaren 22 kan uppblasas med komprimerad luft pa salt, som visas i fig. 1, eller ocksa kan den utvidgas medelst en tryckvatska, vilkens avlopp strypes for att astadkomma onskat mottryck. For detta Andamal Sr hylsan 20 forsedd med ytterligare en roransats 53, i vilken Sr fastskruvat ett avloppsriir 54, vilket Sr forsett med ett T-rOr 55 och en strypventil 56. Med T-roret 55 Sr Mrbunden en manometer 57, som visor det er- — —3 hallna mottrycket, nar ratten 58 pa strypventilen 56 drages at for att delvis stanga strypventilen 56. The modified sealing device, generally designated 50 and shown in Figures 3 and 4, is in principle similar to the sealing device 10 shown in Figures 1 and 2, and similar parts therefore have the same designations. In Fig. 3, however, the cooling and heating device is omitted. The hollow, annular inlet 17 resp. 26 are exchanged for solid, annular parts 51 resp. 52, and these limos are either bolted to or otherwise secured in the spaces previously occupied by the hollow annular portions 17 and 26 of Figs. 1 and 2. The annular chamber 22 can be inflated with compressed air on salt. , as shown in Fig. 1, or it can also be enlarged by means of a pressure vessel, the drain of which is throttled to produce the desired back pressure. For this purpose, the sleeve 20 is provided with a further pipe fitting 53, in which Sr is screwed a drain pipe 54, which Sr is provided with a T-pipe 55 and a throttle valve 56. With the T-pipe 55, a manometer 57 is connected, which indicates that - - —3 hold the back pressure when the knob 58 on the throttle valve 56 is pulled to partially close the throttle valve 56.

I stallet for tuberna 25, som ocksa tjana sasom armering vid utforingsformen enligt fig. 1 och 2, ar tatningsanordningen 50 enligt fig. 3 och 4 forsedd med massiva stanger 59 med kvadratisk sektion, vilka aro ingjutna i det gummiartade material, av vilket bekladnaden 21 bestar. Den kvadratiska formen pa dessa stanger 59 astadkommer en bathe bindning med namnda material. Andarna av stangerna 59 aro fastsvetsade eller pa annat lampligt satt fasta vid ringformiga plattor 60 och 61, vilka aro insatta mellan flansarna 13 och 14 resp. 15 och 16. Stangerna 59 kunna tillverkas av nagot lampligt material, sasom kalldraget stal. Deras inre ytor ligga fria och tjanstgora sasom gejder for skraporna 40. Stangerna 59 forhindra aven, att gummit eller det gummiliknande materialet i bekladnaden 21 skadas, nfir transportorskraporna foras genom densamma. Instead of the tubes 25, which also serve as reinforcement in the embodiment according to Figs. 1 and 2, the sealing device 50 according to Figs. 3 and 4 is provided with solid rods 59 of square section, which are molded into the rubbery material, of which the cladding 21 bestar. The square shape of these rods 59 provides a good bond with said material. The spirits of the rods 59 are welded or otherwise suitably attached to annular plates 60 and 61, which are inserted between the flanges 13 and 14, respectively. 15 and 16. The rods 59 can be made of some suitable material, such as cold drawn steel. Their inner surfaces are free and serve as guides for the scrapers 40. The rods 59 also prevent the rubber or the rubber-like material in the cladding 21 from being damaged by the conveyor scrapers being passed through it.

Den modifierade tatningsanordningen, som generellt betecknas med 62 och sorn visas i fig. 5 och 6, är nastan identisk med tatningsanordningen 50 enligt fig. 3 och 1 med undantag darav, att stangerna 59 aro fullstandigt inbaddade i och tackta av det gummiliknande materialet i bekladnaden 21. The modified sealing device, generally designated 62 and shown in Figures 5 and 6, is almost identical to the sealing device 50 of Figures 3 and 1 except that the rods 59 are completely embedded in and thanked by the rubber-like material in the liner. 21.

De i fig. 1-6 visade utforingsformerna verka sá, att kammaren 22 i beklfidnaden 21 till-cores ett tryckmedium, lampligen komprimerad luft, genom roret 24. Om en vatska skall anvandas och dess avlopp skall strypas, Kan yttcrligare ett ror 54 (fig. 3 och 5) anvfindas, varvid strypventilen 56 Wiles stangd, till dess att ett onskat mottryck avlases pa manometern 57. I de former av uppfinningen, som visas i fig. 3 och 5, kan den vatska, som anvandes for utvidgningen av bekladnaden 21, aven anvandas sasom avkylnings- eller uppvarmningsmedium alit efter onskan. I den form av uppfinningen, som visas i fig. 1, tillfores emellertid avkylnings- eller uppvarmningsmediet genom roret 18, passerar darefter den ringforrniga, ihaliga delen 17, tuberna 25 saint den ihaliga, ringformiga delen 26 och avgar slutligen genom roret 27. The embodiments shown in Figs. 1-6 act so that the chamber 22 in the liner 21 is supplied with a pressure medium, suitably compressed air, through the pipe 24. If a liquid is to be used and its drain is to be throttled, a further pipe 54 can be provided (Fig. 1). 3 and 5) are used, the throttle valve 56 being closed until a desired back pressure is read on the manometer 57. In the forms of the invention shown in Figs. 3 and 5, the liquid used for the expansion of the liner 21 , also used as a cooling or heating medium alit as desired. However, in the form of the invention shown in Fig. 1, the cooling or heating medium is supplied through the tube 18, then passes the annular hollow portion 17, the tubes 25 to the hollow, annular portion 26 and finally exits through the tube 27.

Nar tatningsanordningen 10, 50 eller 62 salunda aro utsatta f Or tryck, komma skraporna 40 att ligga tall an mot de inre ytorna av bekladnaden 21, vilken deformeras sa, att den tatt anligger mot skraporna 40. Foljaktligen halles det tryck, som är radande i roret 12, oforanclrat, aven oat en liten del av tryckvatskan fores bort mellan de pa varandra foljande skraporna 41. When the sealing device 10, 50 or 62 is thus exposed to pressure, the scrapers 40 come to abut against the inner surfaces of the cladding 21, which is deformed so that it abuts against the scrapers 40. Consequently, the pressure which is radiating in the tube 12, unclosed, even though a small part of the pressure vessel is removed between the successive scrapers 41.

I fig. 7 visas ett skraptransportorsystem, generellt betecknat med 70, for transport av material, som skall uppvarmas, sasom fodoamnen, vilka samtidigt skola transporteras. Transportorsystemet 70 omfattar ett trycktatt ledningsparti 71, vilket har en tatningsanord ning 10 vid sina bada andar och passeras av en skraptransportor 30, Overensstammande med den i fig 1 och 2. visade. Alltefter onskan kan Oxen tatningsanordningen 50 eller 62 anvandas. Skraporna 41 i transportoren 30 passa lost i ledningspartiet 71, sa att amp eller annat uppvarmningsmedium kan fritt passera omkring deras periferier och pa sa satt genomtranga det inre av ledningspartiet 71 melIan tatningsanordningarna 10. Fig. 7 shows a scraper conveyor system, generally denoted by 70, for transporting materials to be heated, such as the photo blanks, which are to be transported at the same time. The conveyor system 70 comprises a pressurized conduit portion 71, which has a sealing device 10 at its two ends and is passed by a scraper conveyor 30, In accordance with that shown in Figs. 1 and 2. As desired, the Oxen sealing device 50 or 62 can be used. The scrapers 41 in the conveyor 30 fit loosely in the conduit portion 71, so that amps or other heating medium can pass freely around their peripheries and thus penetrate the interior of the conduit portion 71 between the sealing devices 10.

For driften av transportOren 30 passerar denna Over ett drivhjul 72, vilket är anbragt pa en axel 73, som uppbar en remskiva 74, vilken drives av en rem 75 frau en annan remskiva 76 pit en reduktionsvaxel 77. Dennas remskiva 78 är forbunden genom en rem 79 med en drivskiva 80, som är monterad pa en axel 81 till en elektrisk motor 82. Denna drivanordning är monterad pa en bottenplat 83, fast genom styrjarn 84 vid ett stativ 85, vilket fir svetsat eller pa annat lampligt satt forenat med den utkragade transportorledningens tillopps- och avloppspartier 86 resp. 87. For the operation of the conveyor 30, it passes over a drive wheel 72, which is mounted on a shaft 73, which carried a pulley 74, which is driven by a pulley 75 from another pulley 76 to a reduction shaft 77. Its pulley 78 is connected by a belt 79 with a drive pulley 80, which is mounted on a shaft 81 of an electric motor 82. This drive device is mounted on a base plate 83, fixed through the guide rail 84 to a frame 85, which is welded or otherwise suitably connected to the cantilevered conveyor line. inlet and drainage sections 86 resp. 87.

Tilloppspartiet 86 dr vid ena anden for-sett med en ficka 90, genom vilken materialet matas in i transportoren, och en avloppsledning finnes vid motsatta anden av ledningspartiet 71 omedelbart bakom tatningsanordningen 10, som har en avloppsoppning 91 a i densamma. For att kunna aylagsna sadana smapartiklar av materialet, vilka annars ha benagenhet att fastna vid skraptransportoren 30, kan en lamplig vibrationsapparat 92 placeras ovanfOr ledningen 91. The pressurized line part 71 is provided with inlet and drain pipes 88 resp. 89 for the addition and removal of any heat treatment or cooking medium, as indicated. The inlet portion 86 dr at one end is provided with a pocket 90, through which the material is fed into the conveyor, and a drain line is located at the opposite end of the line portion 71 immediately behind the sealing device 10, which has a drain opening 91a therein. In order to be able to lay such small particles of the material, which otherwise have a tendency to stick to the scraper conveyor 30, a suitable vibrating apparatus 92 can be placed above the line 91.

Denna vibrationsapparat 92 bestar i korthet av en bottenplatta 93, pa -vilken är monterad en motor 94, vars remskiva 95 uppbar en rem 96, som driver remskivan 97 pa en axel 98, vilken i sin tur uppbar ett excentriskt svanghjul 99, lagrat i stativet 100. This vibrating apparatus 92 briefly consists of a base plate 93, on which is mounted a motor 94, the pulley 95 of which carries a belt 96, which drives the pulley 97 on a shaft 98, which in turn carried an eccentric flywheel 99, mounted in the frame 100.

For att rengora transportoren 30 frail fodoamnen eller partiklar av andra materialier, sedan de tappats ur transportOrledningens mellanparti 101, kan lampligen darefter anordnas en rengoringsanordning 102. Denna bestar av ett ihaligt, ladliknande rum med ett tilloppsror 103, ett avloppsrOr 104 for t. ex. anga samt ett draneringsror 105. In order to clean the conveyor 30 of the feedstocks or particles of other materials, after they have been drained from the intermediate portion 101 of the conveyor line, a cleaning device 102 can then suitably be provided. anga and a drainage pipe 105.
