Description
Foreliggende oppfinnelse vedrører en forvarmeinnretning for varme-kjøleblander-kombinasjoner, ved hvilken fin-eller grovkornete råmaterialer som skal prepareres for spesielt kunststoffer oppvarmes i en hurtigmikser opp til den nødvendige temperatur for den foreliggende blanding, og blandingsgodset deretter avkjøles i en kjøleblander inntil det kan lagres og transporteres. The present invention relates to a preheating device for heat-cooling mixer combinations, in which fine- or coarse-grained raw materials to be prepared for plastics in particular are heated in a high-speed mixer to the required temperature for the mixture in question, and the mixture is then cooled in a cooling mixer until it can be stored and transported.
Ved varme- og kjøleblander-kombinasjoner er det kjent å utføre oppvarmningsoperasjonen ved blandeprosessen ved hurtige blandegodsbevegelser og/eller oppvarmning av blan-derbeholderveggen og kjøleprosessen ved hjelp av vannkjø-ling (tidsskrift "Kunststoffe"' 1970," s. 829-832). Behovet for kjølevann kan herunder være betraktelig når dette etter tilbakekjølingen ledes vekk som avløpsvann. Varmen fra kjølevannet går imidlertid i de fleste tilfeller tapt. Varmeprosessen betinger, spesielt når det gjelder å korte blandetidene, en stor energitilførsel for oppvarmning av blandergodset, når f.eks. finkornete materialer skal blandes, fordi disse trenger lengere blande- henh. oppvarm-ningstider enn grovere materialer. In the case of heating and cooling mixer combinations, it is known to carry out the heating operation during the mixing process by rapid mixing material movements and/or heating of the mixer container wall and the cooling process by means of water cooling (journal "Kunststoffe"' 1970," pp. 829-832). The need for cooling water can therefore be considerable when this is led away as waste water after recooling. However, the heat from the cooling water is lost in most cases. The heating process requires, especially when it comes to shortening the mixing times, a large input of energy for heating the mixing material, when e.g. Fine-grained materials must be mixed, because these need longer mixing-related heating times than coarser materials.
Oppgaven for foreliggende oppfinnelse ligger derfor i å tilveiebringe en forvarmeanordning av den innledningsvis nevnte art, som påskynder oppvarmningen av blandegodset og sparer energi. The task of the present invention therefore lies in providing a pre-heating device of the type mentioned at the outset, which speeds up the heating of the mixture and saves energy.
Denne oppgave løses ifølge oppfinnelsen ved de karakteri-stiske trekk som fremgår av hovedkravets karakteriserende del. According to the invention, this task is solved by the characteristic features that appear in the characterizing part of the main claim.
Videre utførelsesformer av oppfinnelsen fremgår av under-kravene. Further embodiments of the invention appear from the sub-claims.
I det følgende beskrives oppfinnelsen som et utførelses-eksempel vist på tegningen. In the following, the invention is described as an embodiment shown in the drawing.
Den skjematiske tegning viser en varme-kjøleblander-kom-binasjon, ved hvilken de fin- til grovkornete materialer The schematic drawing shows a heating-cooling mixer combination, in which the fine- to coarse-grained materials
(chargergods) som skal blandes fra forrådsbeholderen VB transporteres gjennom tilførselsrør til varmeblanderbeholderen HB. Godset som blandes og oppvarmes i varmeblanderbeholderen HB kommer deretter i en kjøleblanderbehol-der KB og fjernes fra denne etter avsluttet kjøleprosess. Avkjøling av blandegodset i kjøleblanderbeholderen skjer ved hjelp av en kjølevæske. Varmen som foreligger i kjø-levæsken som strømmer ut fra kjøleblanderbeholderen KB anvendes gjennom en varmepumpe WP til forvarmning av råmaterialene før de kommer inn i varmeblanderbeholderen, og føres av denne grunn til et varmevekslersystem WS mellom material-forrådsbeholderen MB og varmeblanderbeholderen HB. (charger goods) to be mixed from the storage container VB is transported through supply pipes to the heat mixer container HB. The goods that are mixed and heated in the heating mixer container HB then enter a cooling mixer container KB and are removed from this after the cooling process has been completed. Cooling of the mixed material in the cooling mixer container takes place with the help of a cooling liquid. The heat contained in the cooling liquid flowing out of the cooling mixer container KB is used through a heat pump WP to preheat the raw materials before they enter the heating mixer container, and is therefore led to a heat exchanger system WS between the material storage container MB and the heating mixer container HB.
I utførelseseksemplet strømmer kjølevæsken som føres i sirkulasjon med en temperatur på 25°C fra kjøleblander-beholderen KB i den kalde del av varmepumpen WP, som kjø-levæsken kommer * ut fra med en temperatur på 15 oC og til-føres igjen kjøleblanderbeholderen for avkjøling av blandegodset som kommer inn ved 120°C ned til 40°C. In the design example, the coolant that is circulated at a temperature of 25°C flows from the cooling mixer container KB in the cold part of the heat pump WP, from which the cooling liquid exits * at a temperature of 15 oC and is fed back into the cooling mixer container for cooling of the mixture that enters at 120°C down to 40°C.
Oppvarmningsvæsken som føres i sirkulasjon og strømmer ut fra varmedelen av varmepumpen WP med 55°C tilføres varmeveksleren WT, strømmer gjennom denne motsatt material-transportretningen og varmer derunder råmaterialene som kommer med en romtemperatur på 20°C fra forrådsbeholderen MB, slik at disse kommer i varmeblanderbeholderen HB med en temperatur på 50°C. The heating liquid which is circulated and flows out from the heating part of the heat pump WP at 55°C is supplied to the heat exchanger WT, flows through this in the opposite material transport direction and heats the raw materials that come with a room temperature of 20°C from the storage container MB, so that these come in the heat mixer vessel HB with a temperature of 50°C.
De fordeler som oppnås ved oppfinnelsen består spesielt i at man i forhold til tidligere preparering av spesielt The advantages achieved by the invention consist in particular in that, in relation to the previous preparation of particular
kunststoffer gjennom forvarmningen av materialene som skal blandes under utnyttelse av varmen som er tilstede i kjø-levæsken før chargeringen i blanderbeholderen sparer bety-delig energi og oppnår kortere varme- henh. blandetider. plastics through the preheating of the materials to be mixed using the heat that is present in the coolant before charging in the mixer container saves considerable energy and achieves shorter heating requirements. mixing times.
Forvarmeanordningen ifølge oppfinnelsen kan ikke bare anvendes med hell på kunststoffer, men også på andre stoffer. The preheating device according to the invention can not only be used successfully on plastics, but also on other substances.
