Technical field
The utility model belongs to the solar-photovoltaic technology field, relates to the thermometric visor in a kind of hydrogenation furnace, particularly relates to a kind of corrugated tube double glass viewing mirror that is used for hydrogenation furnace.
Background technology
In recent years, domestic production of polysilicon technology high-speed development was adopted Siemens Method yet produce polysilicon 80% now, when Siemens Method prepares polysilicon, had also generated a large amount of accessory substance SiCl
4, SiCl
4Not only waste starting material, deal with improperly also and can cause the serious environmental pollution problem, in order to reduce production costs, recycling raw materials for production prevent the pollution of the environment, and urgent need is processing of SiC l effectively
4Hydrogenation furnace.
Need control each technology mouth by temperature in the observation stove during hydrogenation furnace running, to keep the operation of equipment stability and high efficiency, this just need be provided with one or several thermometric visor in hydrogenation furnace.
At present, the special-purpose visor that does not also have hydrogenation furnace, visor commonly used is simple in structure, and hydrogenation furnace is jacket structured, fairlead need be set connect visor and equipment, because the device interior temperature of reaction is very high, the cylindrical shell and the chuck temperature difference are very big, cause the periodic expanded by heating of fairlead and cause weld fatigue to destroy and the crack occurs, and the heat resisting temperature of endoscopy glass is limited, so need to adopt new structure, can the key position of visor be cooled off, can prevent that again weld fatigue from destroying.
The utility model content
The purpose of this utility model is to provide a kind of corrugated tube double glass viewing mirror that is used for hydrogenation furnace, be used to solve hydrogenation furnace equipment inner barrel and chuck excessive temperature differentials, and the technical matters that causes weld fatigue that visor fairlead expanded by heating causes to destroy also will solve the cooling problem of endoscopy glass simultaneously.
In order to realize the purpose of this utility model, the corrugated tube double glass viewing mirror that is used for hydrogenation furnace of the present utility model, it comprises the outside flange that is connected to a fixed, outer endoscopy glass, spacer flanger, introscope glass and inner flange successively, and described inner flange is connected with the inner barrel of hydrogenation furnace by fairlead.Described fairlead is arranged with the corrugated tube with its concentric outward, and described corrugated tube one end links to each other with described inner flange, and the other end links to each other with described chuck cylindrical shell.
Wherein, described outer endoscopy glass, described spacer flanger and described introscope glass form a water cooling chamber, and the described spacer flanger outside is respectively equipped with cooling water inlet pipe and cooling water outlet pipe, and communicates with described water cooling chamber.
Described cooling water inlet pipe and cooling water outlet pipe all radially are fixed on the spacer flanger outside.
Described corrugated tube is connected by pipe nipple with described inner flange the inner, is connected by outer forging pipe with described chuck cylindrical shell.
Described fairlead is connected by interior forging pipe with described inner barrel.
Described outside flange, outer endoscopy glass, spacer flanger, introscope glass and inner flange are connected by the fastening screw screw bolt and nut.
The principle of work that the utility model is used for the corrugated tube double glass viewing mirror of hydrogenation furnace is: during hydrogenation furnace work, the fairlead expanded by heating, cool off fairlead in the gap of cooling water flow in the chuck cylindrical shell between corrugated tube and fairlead, reduce thermal expansion amount, and absorb the residue swell increment by corrugated tube.Chilled water cools off endoscopy glass by water cooling chamber through water inlet pipe and water outlet pipe.
The utility model is compared with prior art, has the following advantages:
1. the utility model sheathed corrugated tube outside fairlead, utilize the gap between corrugated tube and the fairlead to fill chilled water, fairlead and inner flange are cooled off, and utilize corrugated tube to absorb the thermal expansion of fairlead, the fatigure failure of having avoided temperature variation to produce has guaranteed the safe operation of equipment.
2. between the ectonexine visor, water cooling chamber is set, feed chilled water by external pipeline endoscopy glass is cooled off, and double-deck endoscopy glass has improved the security of visor.
