Abstract

This invention relates to a gearing and overload safety device for use in connection with worm conveying of solid fuel. The novelty of the invention consists in a drive system for a stoker worm, which system has a high gear ratio and a minimum of power loss, and in a spring for adjustment of the maximum load, which spring simultaneously acts as an overload safety device for the stoker worm. Also, the system is of simple construction with few wearing parts.

Benævnelse.Denominations.

Stokerfremføringssystera til fyringsanlæg.Stoker feeding systems for combustion plants.

Frembringelsens anvendelsesområder.Areas of application of production.

Denne frembringelse angår et udvekslings- og overbelastningssikringssystem til sneglefremføring af brændsel.This generation relates to an exchange and overload protection system for the auger feed of fuel.

Denne frembringelse er især velegnet til stokerfyringsanlæg, hvor man har behov for meget store udvekslinger og behov for hurtig ændring af udvekslingen. Dette kan forekomme ved forskellige volumen/vægt forhold.This generation is particularly suitable for stoker firing systems where very large exchanges are needed and the need for rapid change of the exchange. This may occur at different volume / weight ratios.

Kendt teknik.Prior art.

På eksisterende stokere af forskellige fabrikater, benytter man som oftest et udvekslingsforhold 600:1. Første trin i udvekslingen er et snekkegear med udvekslingen 100:1 og derefter kædeudveksling 6:1.Denne metode giver et stort krafttab samt et stort moment.Existing stokers of different makes usually use an exchange ratio of 600: 1. The first step in the exchange is a worm gear with the exchange 100: 1 and then the chain exchange 6: 1.This method gives a great power loss as well as a large torque.

Ved blokering af snegl med et fremmedlegeme, skal motoren gå i stå, evt. klippes sikringsbolt eller i værste fald knækker kæden, hvis den er slidt.When blocking the auger with a foreign body, the engine must stop, if necessary. clipped securing bolt or at worst the chain breaks if worn.

Det tekniske problem, der skal løses.The technical problem to be solved.

De kendte teknikker har den ulempe, at der som regel forekommer en sprængt kæde eller en sammenbrændt motor som følge af en evt. blokering af sneglen.The known techniques have the disadvantage that there is usually a ruptured chain or a collapsed engine as a result of a possible failure. blocking the auger.

Med frembringelsen ønskes der tilvejebragt et forbedret stoker-system. Et system der er enkelt i opbygning, med stor udveksling med minimum krafttab og med en fjeder til justering af maximum belastning, der samtidig virker som overbelastningssikring af fremføringssneglen.With the creation, it is desired to provide an improved stoker system. A system that is simple in construction, with a large exchange with minimum power loss and with a spring for adjusting maximum load, which at the same time acts as overload protection of the feed auger.

Den nye teknik.The new technique.

Det nye ved frembringelsen udgøres af, at en krumtap bevægelse trækker friløbslejerne,som trækker sneglen et stykke fremad og ved tilbageslag står sneglen stille.The new feature in the production is that a crank movement pulls the free-running bearings, which pull the auger forward and at a setback, the auger stands still.

Hvad enten rotationen af sneglen forekommer ved tryk eller træk, skal der som sikring anvendes en trykfjeder ved trykrotation. Ved trækrotation, forlænges drivarmen således at fjederen monteres på den anden side af udvekslingsarmen, herved kommer fjederen til at virke som trykfjeder.Whether the rotation of the auger occurs by pressure or tension, a compression spring must be used for pressure rotation. With pull rotation, the drive arm is extended so that the spring is mounted on the other side of the exchange arm, thereby causing the spring to act as a compression spring.

Endvidere kan hurtig ændring af udvekslingen ske ved, at ændre kraftpåvirkningens arm. Enten ved at flytte tryk/træk-stangen i huller eller trinløs i en slidse.Furthermore, rapid change of the exchange can be done by changing the arm of the force force. Either by moving the push-pull bar into holes or steplessly in a slot.

Overbelastningssikringen kan i princippet køre uendeligt uden beskadigelse af vitale dele.The overload protection can in principle run endlessly without damaging vital parts.

Den tekniske virkning.The technical impact.

Ved at anvende ovenfor nævnte teknik får man et funktionelt fyringsanlæg, enkelt i opbygning og et frembringelsessystem bestående af få dele.By using the above-mentioned technique, one obtains a functional combustion plant, simple in construction and a production system consisting of few parts.

Frembringelsen og udførelsesformer forklares i enkeltheder i det følgende under henvisning til tegninger.The invention and embodiments are explained in more detail below with reference to the drawings.
