Abstract
The utility model provides a splicing straight pulling single crystal furnace solidification thermal insulation barrel. The splicing straight pulling single crystal furnace solidification thermal insulation barrel overall is of a conical tubular structure and comprises an upper thermal insulation barrel section, a middle thermal insulation barrel section and a lower thermal insulation barrel section which are respectively of a bilayer structure, namely an inner layer structure and an outer layer structure, the outer layer structure is formed by processing solidification felt leftover materials cut off during polycrystal furnace thermal field process according to the size of a concrete single crystal furnace thermal insulation barrel, and the thermal insulation barrel is formed by hooping and fixing at sections by adopting high temperature resistant molybdenum wires. A production period is several days only, leftover materials for producing other products are taken as raw material, so that the defect that an integral type solidification thermal insulation barrel is high in cost is overcome; meanwhile, waste is utilized, resource is not wasted, the environment is not polluted, and energy conservation and emission reduction are realized.
Description
Technical field
The utility model relates to a kind of splice type czochralski crystal growing furnace and solidifies insulated tank, belongs to field of mechanical technique.
Background technology
Czochralski crystal growing furnace is semicon industry and the important production unit of photovoltaic industry, although this year, photovoltaic industry was received certain impact, development prospect is still become better.Because single crystal growing furnace is high-energy equipment, so the heat-insulating property of thermal field is just extremely important, single crystal growing furnace is in the past all generally that the mode that is wound around with soft felt is as the thermal insulation layer of single crystal growing furnace, this material price is cheap, easy to use, but heat-insulating property is poor, corrosion resistance is short poor work-ing life, within general about 1 year, just need blowing out to change thermal insulation layer, impurity and ash content high, the raising of industry requirement thereupon, such as N-type cell piece, high-efficiency battery sheet.Especially semicon industry is had higher requirement in every respect for pulling of crystals silicon chip, the more and more not competent such demand of soft felt that traditional soft felt is especially domestic, after serve high-end type such as the Kai Kesi of the U.S., there is all-in-one-piece curing felt insulated tank on Mitsubishi's stove of Japan.Solidifying the softer felt of felt insulated tank heat insulation effect is significantly improved, corrosion resistance also significantly improves work-ing life, general continuous production is more than 3 years, but also brought unit price very expensive, need customization and very long problem of customized production cycle, from being dosed into out product, generally need about 6 months.
Utility model content
The utility model provides a kind of splice type czochralski crystal growing furnace to solidify insulated tank, can overcome the above defect, high insulating effect, and making processes energy-conserving and environment-protective, and fabrication cycle is short.
For solving above technical problem, the utility model provides following technical scheme: a kind of splice type czochralski crystal growing furnace solidifies insulated tank, described curing insulated tank integral body is conic tube structure, the insulated tank that comprises three segmentations in upper, middle and lower, the insulated tank of three segmentations of upper, middle and lower is bilayer structure, be divided into endothecium structure and layer structure, described layer structure is formed by the curing felt cutting of polycrystalline ingot furnace thermal field, and described insulated tank is shaped and formed well by resistant to elevated temperatures molybdenum filament hoop in segmentation place.
Further, described endothecium structure by graphite or CC insulated tank as support.
Further, described layer structure by hard felt material as thermal insulation layer.
Further, the cylindrical tube structure of described layer structure for being spliced to form by the parallel close-packed arrays of several heat insulating strips.
Further, the thickness of described layer structure is 50mm.
Further, the top internal diameter of upper insulated tank is 672mm.
Further, the top internal diameter of middle insulated tank is 745mm.
Further, the top internal diameter of outer insulated tank is 762mm.
This splice type czochralski crystal growing furnace that the utility model relates to solidifies insulated tank, described insulated tank has been inherited the high insulating effect of monoblock type insulated tank, the feature of the high long service life of erosion resistance, also overcome the curing insulated tank price customization production cycle of monoblock type long simultaneously, production cycle only needs several days, because raw material is the tailing of producing other products, also overcome the high shortcoming of price that monoblock type is solidified insulated tank, and it is free from environmental pollution to have accomplished that resource is not wasted in utilization of waste material, has accomplished energy-saving and emission-reduction.
