Abstract

Fremgangsmåte til fremstilling av duktilt støpejern og midel til utførelse av fremgangsmåten.Method for the production of ductile cast iron and means for carrying out the method.

Description

Anordning ved tørke- og lagringssilo for korn og liknende materialer. Device for drying and storage silos for grain and similar materials.

For tørking og lagring av korn, særlig For drying and storing grain, in particular

ved mindre jordbruk, har man i den siste tid begynt å anvende tørke- og lagrings-siloer som består av en sylindrisk beholder som er utført av vev av jute eller lignende materialer og oventil er helt åpen og festet in the case of small-scale agriculture, drying and storage silos have recently started to be used, which consist of a cylindrical container made of woven jute or similar materials and the top is completely open and fixed

til en avstivningsring, mens dens nedre del henger fritt ned i en fast utmatningstrakt som er festet i et stativ som under-støtter beholderen, samt et i beholderens sentrum anordnet perforert rør som er tilsluttet et organ for innføring eller bort-føring av luft som bringes til å passere horisontalt gjennom materialet i beholderen. to a stiffening ring, while its lower part hangs freely down into a fixed discharge funnel which is fixed in a stand which supports the container, as well as a perforated tube arranged in the center of the container which is connected to a means for introducing or removing air which is brought to pass horizontally through the material in the container.

Det har imidlertid vist seg at det korn som fyller utmatningstrakten når beholderen er begynt å fylles, vil trekke den i trakten nedhengende del av sylinderveggen med seg inn mot sentrum, hvil-ket fører til at beholderen nedentil får en noe konisk form. Ved fortsatt påfylling av korn vil derfor vekten av kornmassen ikke, som tilsiktet, bli helt avlastet på den faste utmatningstrakt, men delvis over-føres til sylinderveggen. Dette resulterer i en påkjenning som den av jutevev utførte vegg ikke er beregnet for, med den fare at denne vegg kan briste. However, it has been shown that the grain that fills the discharge funnel when the container has begun to fill will pull the part of the cylinder wall hanging down in the funnel towards the center, which causes the container to take on a somewhat conical shape below. In the case of continued filling of grain, the weight of the grain mass will not, as intended, be completely relieved on the fixed discharge funnel, but will be partially transferred to the cylinder wall. This results in a stress that the wall made of jute fabric is not designed for, with the risk that this wall may burst.

En utførelse av en slik beholder er beskrevet i patent 100 281 (hovedpatentet). An embodiment of such a container is described in patent 100 281 (the main patent).

Foreliggende oppfinnelse utgjør en videre utvikling og en forbedring av tørke-og lagringssiloen ifølge dette patent. The present invention constitutes a further development and an improvement of the drying and storage silo according to this patent.

For å eliminere ulempen ved den tid-ligere utførelse av en tørke- og lagringssilo av denne art, nemlig at den del som befinner seg i utmatningstrakten — som ubehandlet — må føres tilbake i siloen for å undergå behandling, er utmatningstraktens mantel ifølge oppfinnelsen helt eller delvis perforert, slik at tørkeluften også vil strømme gjennom det korn som ligger i utmatningstrakten . In order to eliminate the disadvantage of the earlier design of a drying and storage silo of this kind, namely that the part that is in the discharge hopper — as untreated — must be brought back into the silo to undergo treatment, the jacket of the discharge hopper according to the invention is completely or partially perforated, so that the drying air will also flow through the grain in the discharge hopper.

I henhold til en særlig hensiktsmessig utførelse utgjøres perforeringen i utmatningstraktens mantel av i forhold til kornenes størrelse store hull som dekkes av en i trakten nedhengende del av nettet eller veven som utgjør den sylindriske del. According to a particularly suitable design, the perforation in the jacket of the discharge hopper consists of holes large in relation to the size of the grains, which are covered by a hanging part of the net or fabric which forms the cylindrical part in the hopper.
