Description
Innretning til opphetning av granulat av kunstharpiks, Device for heating granules of synthetic resin,
særlig for lydplatepressmasser. especially for sound record pressings.
Til forvarmning av termoplastisk lyd-platemasser som foreligger i form av granulat anvendes varmeovner i kammerform som kan opphetes elektrisk eller med gass eller damp. To preheat thermoplastic sound board masses that are in the form of granules, heaters are used in chamber form that can be heated electrically or with gas or steam.
For å skaffe en tilmålt og or lydplate-pressformen forvarmet mengde av granulatmasse, klar til å gripes av arbeideren ved pressformen, blir f. eks. en varmeovn for granulatmassen delt opp i flere kamre og eventuelt anordnet karusellformet. I pas-sende tidsintervall blir hver gang en por-sjon pressmasse, som fortrinnsvis er bakt sammen til en massekake, forvarmet i ovnskammeret og holdt parat for presning ved ovnsåpningen. In order to obtain a measured and pre-heated quantity of granulate mass, ready to be grasped by the worker at the press mould, e.g. a heater for the granulate mass divided into several chambers and optionally arranged in a carousel shape. At appropriate time intervals, each time a portion of pressed mass, which is preferably baked together into a mass cake, is preheated in the oven chamber and kept ready for pressing at the oven opening.
De nevnte varmeovner til forvarmning They mentioned heaters for preheating
av platemassene oppviser endel ulemper som virker uheldig for lydplatefremstillin-gen: For det første har disse varmeovner en forholdsvis stor varmekapasitet og krever tilsvarende lang tid for å nå den øn-skede temperatur. De granulatporsjoner som befinner seg i de enkelte kamre, opptar varmen ujevnt. Mens de nederste skikt og de enkelte porsjoner på bunnen av det opphetede kammer blir forholdsvis sterkt opphetet ved kontaktvirkning, får de opp-hopede granulatpartikler som hovedsaklig befinner seg i det indre, tilført forholdsvis lite varme. Bortsett fra at varme-energien ved anvendelse av slike ovner blir dårlig utnyttet, har en for langvarig termisk påkjenning av massen uheldige virkninger, særlig kan der ved varmekontaktstedene inntre en overhetning og en dermed forbundet spaltning av massen. of the plate masses exhibit a number of disadvantages that are detrimental to sound record production: Firstly, these heaters have a relatively large heating capacity and require a correspondingly long time to reach the desired temperature. The granule portions in the individual chambers absorb the heat unevenly. While the lowermost layers and the individual portions at the bottom of the heated chamber are relatively strongly heated by contact action, relatively little heat is supplied to the piled-up granulate particles which are mainly located in the interior. Apart from the fact that the heat energy when using such ovens is poorly utilised, too long a thermal stress on the mass has adverse effects, in particular overheating and a consequent splitting of the mass can occur at the heat contact points.
De nevnte ulemper blir ryddet av vei-en ved hjelp av oppfinnelsen, som går ut på en innretning bestemt til opphetning av granulat av kunstharpiks, særlig for lyd-plate-masser, og i første rekke er karakterisert ved at den består av en i og for seg kjent varmluftblåseinnretning og et med denne adskillbart forbundet opphetningsaggregat som dannes av en rørformet beholder hvori massen oppvarmes porsjonert i kunststoffbegre, som er plasert over hverandre og hvis bunner er perforert. Som be-holdere for granulatmassen anvendes for-delaktig ikke-metalliske kar, resp. kar med liten varmekapasitet, f. eks. kunststoffbegre med gjennomhullede, resp. silformede bunner. The aforementioned disadvantages are cleared of the road with the help of the invention, which consists of a device intended for heating granules of synthetic resin, especially for sound-record masses, and is primarily characterized by the fact that it consists of an in and a known hot air blowing device and a separately connected heating unit which is formed by a tubular container in which the mass is heated in portions in plastic cups, which are placed one above the other and whose bottoms are perforated. Non-metallic vessels are advantageously used as containers for the granulate mass, resp. vessels with a small heating capacity, e.g. plastic cups with perforated, resp. sieve-shaped bottoms.
En slik anordning byr på spesielle for-deler. Energibehovet til oppvarmning av granulatet er forholdsvis lite og utgjør bare i /8 sammenlignet med behovet ved anvendelse av en vanlig kammer-forvarmnings-ovn. Den termiske påkjenning av granulatet blir bare kortvarig, og varmetilførselen til granulatet skjer meget jevnt, da varm-luftstrømmen, som også går gjennom granulatmassen, kan overføre sin varme til de enkelte granuler direkte ved konveksjon. Ved anvendelse av begere plasert over hverandre og forsynt med gjennomhullede bunner, blir varmen utnyttet rasjonelt samtidig som en overhetning av granulatet unngås. Da ovnskappen, som fordelak-tig også består av kunststoff, f. eks. kan lages av hårdt papir eller lignende, har hele opphetningsinnretningen bare en liten varmekapasitet. Such a device offers special advantages. The energy requirement for heating the granulate is relatively small and amounts to only 1/8 compared to the requirement when using a normal chamber preheating furnace. The thermal stress on the granulate is only short-lived, and the heat supply to the granulate is very even, as the hot air stream, which also passes through the granulate mass, can transfer its heat to the individual granules directly by convection. By using cups placed one above the other and provided with perforated bottoms, the heat is used rationally while overheating of the granulate is avoided. As the oven cabinet, which advantageously also consists of plastic, e.g. can be made of hard paper or the like, the entire heating device only has a small heat capacity.
