Abstract

PURPOSE:To reduce an equipment cost by utilizing the curved surface of a light reflecting film formed when a light reflecting film having resilience and a transparent film or resin plate, glass plate, etc. are extended to a circular frame so as to face each other and a gas is sealed under pressure to the inside thereof. CONSTITUTION:A light reflecting film 1 consisting of a resin film deposited by evaporation with aluminum and a light incident side transparent resin sheet 4 or resin plate, glass plate 4' are attached to a circular frame 2 consisting of a hard resin or light metal, etc. by using a gasket in a flange type in such a way that the inside thereof is made airtight. Air or other inert gas is then forced into such assembly through a gas introducing port 5 to inflate adequately the light reflecting film. The inflation is adjusted by increasing or decreasing the slack in the stage of attaching the light reflecting film or filling of the air or the gas. When the filling of the air or the gas ends, the material to be heated is exactly directed toward the sun and is set in the focal position to start the use. The equipment cost is thus reduced.

Description

【発明の詳細な説明】 本発明は脱果光装置に関する。[Detailed description of the invention] The present invention relates to a dehulling device.

従来、太陽熱の利用は自然利用のクリーンエネルギー源

鏡により集光し、高熱を得て、発電又は冶金等に利用す

に於て新しい手法が加えられて大規模な試験等が続けら
れ、一部は実用化もなされている。Conventionally, the use of solar heat has attracted attention as a natural source of clean energy, and various methods have been developed. In these methods, the idea of concentrating sunlight with a lens or reflecting mirror to obtain high heat and using it for power generation or metallurgy has been around for a long time, and new methods have been added to this method in various countries around the world. Large-scale tests have been carried out, and some have even been put into practical use.

しかしながら、一般に集光設備はその利用熱量に対して
大規模になりがちで設備コストも嵩むといった経済的な
難点もあり手軽に設置、利用出来るものではないのが現
状である。However, in general, condensing equipment tends to be large-scale in relation to the amount of heat used, and has economical drawbacks such as high equipment costs, and the current situation is that it is not easy to install and use.

本発明者はこれらの問題について鋭意研究な行い、本発

する集光装置である。That is, the present invention is formed when a flexible light reflecting film and a transparent film, a resin plate, a glass plate, etc. are placed facing each other in a circular frame, the inside of which is made airtight, and a gas is pressurized and sealed. This is a light condensing device characterized by using the curved surface of a light reflecting film as a reflecting mirror.

本発明の装置に於ては反射膜ははｙ完全な球面反射鏡を
形成する。In the device of the invention, the reflective film forms a completely spherical reflector.

ィルムが考えられるが、ガス透過率の低さ及び使用温度
範囲の広さよりみて特にポリエステル、又はナイロンに
よるアルミ蒸着フィルムが好適である。Possible materials for the reflective film include polyester, polypropylene, nylon, and aluminum vapor-deposited films made of vinyl chloride, which have a relatively high elongation rate, but aluminum made of polyester or nylon is particularly suitable because of its low gas permeability and wide operating temperature range. Vapor deposited films are preferred.

太陽光の入射側は伸び率が小さく、光の透過率が良く、

用すると装置全体が非常に軽量なものとなり、太陽自動
追従装置に取付けた場合でも機械的な負担は極めて軽く
なり、移動設備とする場合は特に好適である。The elongation rate is small on the sunlight incident side, and the light transmittance is good.
In addition, it is preferable to use a resin film, resin plate, glass plate, etc., which have a low gas permeability. Note that if the film is too thin on the incident side, it will bulge forward, and if the focal point is close, the temperature will rise and the film will be easily damaged. If the frame is also made of hard resin or light metal, the entire device will be extremely lightweight, and even when attached to an automatic solar tracking device, the mechanical burden will be extremely light, making it particularly suitable for use as a mobile facility.

Attach the light reflection film 1 made of aluminum vapor-deposited resin film and the transparent resin sheet 4 on the light incidence side, or the resin plate, or the glass plate 41 using gaskets in a 7-rank manner so that the inside is airtight. Or inflate the light reflecting film appropriately by injecting other inert gas.This bulge will be caused by the slack when installing the bare light reflecting film, which will become the planned focal point 3., and the tension of the air or gas. Once the air or gas has been filled, place the object to be heated at the focal point, facing the sun, and start using it.
