Description
FIG. 3 är en motsvarande längdsektionsvy i funktionsläget åör över¥öring av bulkmaterialet Fran den trycksatta kammaren till utrymmet i ett förgasarkärl eller annat processkärl. FIG. 3 is a corresponding longitudinal sectional view in the functional mode of transferring the bulk material from the pressurized chamber to the space in a carburettor vessel or other process vessel.
I FIG. I visas en sluss, som inne¥attar en vertikalt anornad cvlindrisk kammare 10 med en ett stycke nedanför dess övre ände anordnad ingangssuts 11 pà sidan. Kammarens nedre ände bildar en utgång 12, som skall vara ansluten till ett utrymme (inte visat) under övertryck, exempelvis ett processkärl, och är anordnad med en ventil lä. Till kammaren är anslutet ett inlopp 14 åör tryckgas, äörsett med en avstängningsventil 15.In FIG. I shows a lock which encloses a vertically arranged cylindrical chamber 10 with an entrance socket 11 arranged a short distance below its upper end. The lower end of the chamber forms an outlet 12, which is to be connected to a space (not shown) under overpressure, for example a process vessel, and is arranged with a valve shelter. An inlet 14 for compressed gas is connected to the chamber, provided with a shut-off valve 15.
För avstängning av förbindelsen mellan íngàngsstutsen 11 och kammaren 10 är anordnad en in i kammaren axiellt förskjutbar rörêormig slid lå, vilken medelst en styrning 17 är styrd för rätlinig axiell rörelse och är Förskjutbar mellan det i FIG. 1 visade tillbakadragna läget och det i FIG. 2 och 3 visade inskjutna läget medelst en hydraulcylinder IB. Kammaren 10 har i sin övre del större diameter och övergàr vid en ansats 19 i en mindre diameter. Sliden är inskjutbar endast i den vidare övre delen av kammaren, och den behöver inte ha tätande passning mot kammarväggens insida. Den har en innerdiameter, som överensstämmer med eller kan vara obetydligt mindre än innerdiametern hos den snävare nedre delen av kammaren, så att slidens insida, da sliden är inskjuten i kammarens vidare övre del, ligger huvudsakligen jäms med insidan hos kammarens snävare nedre del. I kammarens 10 vägg är anordnat ett expansibelt tåtníngsdon 20, iöreträdesvis i ¥orm av en eller flera mot slidens utsida hydrauliskt ansättbara tätningsringar ¥ör efëektiv avtätning av kammarens 10 snävare nedre del mot den övre delen och mot ingàngsstutsen. Tätningsringarnas antal bestämmer tätningsdonets e¥%ektivitet och Far väljas eçter den säkerhetsniva som önskas. En fördel är, att tätningsringarna inte är känsliga För mindre materialkorn som eventuellt kläms fa. (_ |\ \D CD -<1 CD fast mot slíden vid ansättningen av tätningsringarna mot denna.To shut off the connection between the inlet nozzle 11 and the chamber 10, a tubular slide is arranged which is axially displaceable into the chamber, which means is guided by means of a guide 17 for rectilinear axial movement and is displaceable between that shown in FIG. 1 and the position shown in FIG. 2 and 3 show the retracted position by means of a hydraulic cylinder IB. The chamber 10 has a larger diameter in its upper part and changes at a shoulder 19 into a smaller diameter. The slide is retractable only in the further upper part of the chamber, and it does not have to have a sealing fit against the inside of the chamber wall. It has an inner diameter which corresponds to or may be slightly smaller than the inner diameter of the narrower lower part of the chamber, so that the inside of the slide, when the slide is inserted into the further upper part of the chamber, is substantially flush with the inside of the narrower lower part of the chamber. Arranged in the wall of the chamber 10 is an expansible sealing device 20, preferably in the form of one or more sealing rings which can be hydraulically applied to the outside of the slide, for effective sealing of the narrower lower part of the chamber 10 against the upper part and against the inlet socket. The number of sealing rings determines the e ¥% activity of the sealant and Far is selected according to the desired safety level. An advantage is that the sealing rings are not sensitive to smaller material grains that may be pinched. (_ | \ \ D CD - <1 CD fixed to the slide when applying the sealing rings to it.
Inuti sliden lo är förskjutbart styrd en rörformig kolv 21, vilken är förskjuthar mellan det i FIG. 1 visade läget och det i FIG. 3 visade läget medelst en hydraulcylinder 22, som är fast förankrad vid 23. Med sliden i det stängda läget enligt FIG. 2 kan kolven medelst hydraulcylindern 22 för- skjutas kontinuerligt genom sliden och in i kammarens 10 snävare nedre del, eftersom sliden och denna del av kammaren bildar ett kontinuerligt cylinderlopp. Som nämndes ovan, kan slidens innerdiameter vara nagot mindre än innerdiametern hos kammarens snävare del, innebärande att kolven inte är tättslutande mot kammarväggens insida eller ens löper i kontakt med denna. I slidens övre ände är anordnad en glidtätning 24 för tätning mellan sliden och kolven. Denna tätning eliminerar risken för att material, damm och dylikt tränger in mellan sliden och kolven och förorsakar onödig förslitníng. Spärrvätska eller spärrgas kan eventuellt införas i tätningen 24.Inside the slide 10, a tubular piston 21 is slidably guided, which is displaceable between that in FIG. 1 and the position shown in FIG. 3 shows the position by means of a hydraulic cylinder 22, which is fixedly anchored at 23. With the slide in the closed position according to FIG. 2, the piston can be displaced continuously by means of the hydraulic cylinder 22 through the slide and into the narrower lower part of the chamber 10, since the slide and this part of the chamber form a continuous cylinder bore. As mentioned above, the inner diameter of the slide may be slightly smaller than the inner diameter of the narrower part of the chamber, meaning that the piston does not close tightly to the inside of the chamber wall or even runs in contact with it. At the upper end of the slide, a sliding seal 24 is arranged for sealing between the slide and the piston. This seal eliminates the risk of material, dust and the like penetrating between the slide and the piston and causing unnecessary wear. Inlet fluid or inlet gas may optionally be inserted into the seal 24.
Vid tillämpning av sättet enligt SE 9003172-5 med användning av den här beskrivna apparaten förfares enligt följande: I utgangsläget, som är visat i FIE. 1, är sliden 16 i det tillbakadragna läget, sa att ingàngsstutsen 11 har förbindelse med kammaren 16. ventilen 13 är stängd, sa att processkärlet är skilt fran kammaren 1D, och ventilen 15 för trycksättningen av kammaren är ocksa stängd.When applying the method according to SE 9003172-5 using the apparatus described here, proceed as follows: In the initial position, which is shown in FIE. 1, the slide 16 is in the retracted position, so that the inlet nozzle 11 is connected to the chamber 16. the valve 13 is closed, so that the process vessel is separate from the chamber 1D, and the valve 15 for pressurizing the chamber is also closed.
Det antages, att ingangsstutsen 11 är ansluten till en tillfërselanordning för bulkmaterial och att sàdant material nu matas in i kammaren 10 via ingàngsstutsen och får utfylla kammarens snävare nedre del, den del som befinner sig nedanför ansatsen 19.It is assumed that the inlet nozzle 11 is connected to a supply device for bulk material and that such material is now fed into the chamber 10 via the inlet nozzle and is allowed to fill the narrower lower part of the chamber, the part which is below the shoulder 19.
Nästa fas består i att sliden 16 medelst hydraulcylindern r .|'> CH UD CI) *J CD 18 ¥örskjutes till det inskjutna läget enligt FIG. E. Under denna rörelse hos sliden bringas kolven 21 medelst hydraulcylíndern 22 att medfölja slidens 16 rörelse.The next phase consists in that the slide 16 is displaced by means of the hydraulic cylinder r. | '> CH UD CI) * J CD 18 ¥ to the inserted position according to FIG. E. During this movement of the slide, the piston 21 is caused by the hydraulic cylinder 22 to follow the movement of the slide 16.
Tätningsdonet 20 ansättes mot slidens utsida. Materialet i den nu mot sàväl atmos§ären som processkärlet tillslutna kammaren 10 kan därefter i vissa ¥all komprimeras nagot, beroende pa vilket material det är fraga om, genom att kolven 21 förskjutes ytterligare nedàt och pressar mot materialet. Biomassa kan utan vidare komprimeras till 2/3 av sin ursprungliga volym, medan kornmaterial, exempelvis kol, inte bör komprimeras. Kolven kan under större delen av sin ršrelse ¥örskjutas med relativt lagt tryck, vilket betyder att energi¥örbrukningen kan hållas nere.The sealer 20 is applied to the outside of the slide. The material in the chamber 10 now closed to both the atmosphere and the process vessel can then be compressed to some extent, depending on the material in question, by displacing the piston 21 further downwards and pressing against the material. Biomass can easily be compressed to 2/3 of its original volume, while barley material, such as coal, should not be compressed. During most of its movement, the piston can be displaced with relatively low pressure, which means that energy consumption can be kept down.
Den mellan kolven 31 och ventilen 13 avgränsade volymen i kammaren 10 trycksättes till huvudsakligen samma tryck som det i processkärlet genom att ventilen 15 äppnas, varefter ventilen 13 öppnas och kolven 21 förskjutes till sitt nedre läge, FIG. 3, under inêörsel av bulkmaterialet i processkärlet ëràn den trycksatta kammaren ID. Ned ventilerna 13 och 15 stängda sker därefter àtergàng till utgångsläget enligt FIG. 1.The volume delimited between the piston 31 and the valve 13 in the chamber 10 is pressurized to substantially the same pressure as that in the process vessel by opening the valve 15, after which the valve 13 is opened and the piston 21 is displaced to its lower position, FIG. 3, during insertion of the bulk material into the process vessel before the pressurized chamber ID. When the valves 13 and 15 are closed, there is then a return to the initial position according to FIG. 1.
Den enda del som behöver iinbearbetning är kolvens 21 utsida, som maste ha sadan ytfinhet, att glidtätningen 24 inte förslites. Däremot behöver kolven inte ha tätande anliggníng mot slidens insida.The only part that needs to be machined is the outside of the piston 21, which must have such a surface finish that the sliding seal 24 does not wear. However, the piston does not have to have a sealing abutment against the inside of the slide.
De styrda rörelser som er+ordras i apparaten kan astadkommas och samordnas genom enkel hydraulik.The controlled movements that you + order in the device can be achieved and coordinated by simple hydraulics.
