Description

Transportør for pulver- eller kornformet materiale. Conveyor for powdery or granular material.

Denne oppfinnelse vedrører en trans-portør for pulver- eller kornformet materiale, bestående av en transportrenne med halvsirkelformet bunn og et i transportrennen anordnet skrapeorgan som utgjøres av et antall på en såvel aksialt forskyvbar som vridbar aksel anordnede skrapere ut-ført som sektorformede plater med en sentralvinkel på ca. 180°. This invention relates to a conveyor for powder or grain-shaped material, consisting of a conveyor chute with a semicircular bottom and a scraper arranged in the conveyor chute which consists of a number of scrapers arranged on an axially displaceable as well as rotatable shaft designed as sector-shaped plates with a central angle of approx. 180°.

Transportøren i henhold til oppfinnelsen utmerker seg i det vesentlige ved at transportrennen er forsynt med flere utmatningsåpninger og at skraperne er fordelt langs akselen i grupper på begge sider av hver utmatningsåpning med skraperne i den ene gruppe på den ene side av vedkommende utmatningsåpning forskjøvet 180° i forhold til skraperne i den motsatt anordnede gruppe, og at akselen på i og for seg kjent måte er utstyrt med drivorganer som bibringer akselen en frem- og tilbakegående bevegelse i aksialretningen og etter avsluttet bevegelse i en retning vrir akselen 180° slik at skraperne i de forskjellige grupper vekselvis bringes til arbeidsstilling. The conveyor according to the invention essentially differs in that the transport chute is provided with several discharge openings and that the scrapers are distributed along the axle in groups on both sides of each discharge opening with the scrapers in one group on one side of the relevant discharge opening offset by 180° in relative to the scrapers in the oppositely arranged group, and that the shaft is equipped in a manner known per se with drive means which give the shaft a reciprocating movement in the axial direction and after movement in one direction is finished, the shaft turns 180° so that the scrapers in the different groups are alternately brought to work.

Skraperne er hensiktsmessig utført med festeflenser slik at de avtagbart kan festes på akselen, hvilket gir anledning til tilpasning av skrapernes deling og/eller fordeling innbyrdes. The scrapers are suitably made with attachment flanges so that they can be removably attached to the axle, which gives the opportunity to adapt the division and/or distribution of the scrapers among themselves.

Ved en utførelse av oppfinnelsen er In one embodiment of the invention is

riale som har festet seg på skrapernes begge sider. rials that have stuck to both sides of the scrapers.

For rensning av skraperne og akselen er renseorganene hensiktsmessig utført som ]-formede trådbøyler som er festet til transportrennens sidevegger, hvor bøyle-nes sidearmer renser den ene side av to tilstøtende skrapere, mens trådbøylens midtre parti renser akselens mellomliggende del. For cleaning the scrapers and the shaft, the cleaning means are conveniently designed as ]-shaped wire hoops which are attached to the side walls of the transport chute, where the side arms of the hoops clean one side of two adjacent scrapers, while the middle part of the wire hoop cleans the intermediate part of the shaft.

Oppfinnelsen skal forklares nærmere ved hjelp av et eksempel under henvisning til tegningen, hvor fig. 1 viser et lengde-snitt gjennom transportøren, fig. 2 et tverrsnitt langs linjen II-II på fig. 1, og fig. 3 viser et grunnriss av transportøren. The invention will be explained in more detail by means of an example with reference to the drawing, where fig. 1 shows a longitudinal section through the conveyor, fig. 2 a cross-section along the line II-II in fig. 1, and fig. 3 shows a plan view of the conveyor.

Tegningen viser en transportrenne 1 med en halvsirkelformet bunn 2 med to utleveringsåpninger 3 og 4. Innenfor transportrennen er anordnet en aksel 5 som strekker seg langs rennens hele lengde og er lagret i lageret 6 i rennens endepartier. På akselen er anbrakt et antall skrapere 7, utført som sektorformede plater med en sentrumsvinkel på ca. 180°. Skraperne er anordnet langs hele akselen og oppdelt i grupper A og B på begge sider av hver ut-leveringsåpning. Skraperne i gruppene A på den ene side av utleveringsåpningene er forskjøvet 180° til skraperne i gruppene B på den motsatte side av de nevnte åp-ninger. For at skrapernes deling og/eller fordeling innbyrdes kan tilpasses etter be-hov, er skraperne ifølge eksempelet utført med festeflenser 8 og kan festes avtagbart på akselen 5 ved hjelp av bolter 9. Akselen The drawing shows a transport chute 1 with a semi-circular bottom 2 with two delivery openings 3 and 4. Within the transport chute is arranged a shaft 5 which extends along the entire length of the chute and is stored in the bearing 6 in the end parts of the chute. A number of scrapers 7, designed as sector-shaped plates with a center angle of approx. 180°. The scrapers are arranged along the entire axle and divided into groups A and B on both sides of each delivery opening. The scrapers in groups A on one side of the dispensing openings are offset 180° to the scrapers in groups B on the opposite side of the aforementioned openings. So that the division and/or distribution of the scrapers can be adapted to each other as required, according to the example, the scrapers are made with fastening flanges 8 and can be removably attached to the shaft 5 using bolts 9. The shaft
