Abstract
A quartz tube continuous smelter provided with a secondary heater at the lower part comprises a furnace body and a melting pot arranged in the furnace body, wherein a heat insulation layer is arranged between the melting pot and the wall of the furnace body; the bottom of the furnace body is provided with a furnace mouth of an exit pipe; a molding area is formed between the furnace mouth and the bottom of the melting pot, and provided with the secondary heater; and the furnace mouth is externally provided with an air inducing mechanism. The quartz tube continuous smelter can properly adjust the temperature of the molding area at the bottom of the continuous smelter, improve the forming quality of the quartz tube, control the caloric power by an adjusting control module, and further realize the adjustment of temperature of the molding area at the lower part of the continuous smelter, thus leading the dimension of a former of a certain designed product, the dimension of a material flowing opening, and the temperature of the molding area to be matched to reach an optimal working point, and causing the quantity and the quality of the quartz tube to achieve an optimal status of the design.
Description
Technical field
The utility model relates to a kind of drawing device of quartz glass tube, particularly a kind of quartz ampoule continuous induction melting furnace with bottom second heating apparatus.
Background technology
Existing quartz ampoule continuous induction melting furnace is because electro-heat equipment all is an integral type, and after the stove assembling was finished, between crucible and the heater and space, quartz ampoule shaping district was all to determine.Because it is unreasonable that assembling is arranged, perhaps because the product specification that will change exceeds the adjusting range of original device, want to change and be shaped the temperature in district with the demand that adapts to new product difficulty comparatively, just seem that the adjustable shaping district temperature range that adapts to product is too narrow.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of quartz ampoule continuous induction melting furnace with bottom second heating apparatus.Can suitably regulate shaping district, the bottom temperature of continuous induction melting furnace, improve the forming quality of quartz ampoule.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of quartz ampoule continuous induction melting furnace with bottom second heating apparatus, comprise body of heater and be located at the interior crucible of body of heater, between crucible and the furnace body wall heat-insulation layer is housed, be provided with the top heater between the periphery of crucible and the heat-insulation layer, the bottom of body of heater is provided with out the fire door of pipe, is shaping area between fire door and the crucible bottom, is characterized in: be provided with second heating apparatus at shaping area.
The technical problems to be solved in the utility model can also be come by the following technical programs further to realize, be provided with the air-introduced machine structure outside fire door.
The utility model compared with prior art, the district is provided with second heating apparatus in the bottom shaping, can suitably regulate shaping district, the bottom temperature of continuous induction melting furnace, improves the forming quality of quartz ampoule.Can control the size of its heating power by regulating control module, and then the temperature that realizes regulating shaping district, quartz ampoule continuous induction melting furnace bottom, and make former size, the stream material mouthful size of certain deisgn product and the cooperation of the district's temperature that is shaped reach best operating point, make quartz ampoule amount and quality reach the optimum state of design.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
The specific embodiment
A kind of quartz ampoule continuous induction melting furnace with bottom second heating apparatus, comprise body of heater 2 and be located at the interior crucible 5 of body of heater, heat-insulation layer 3 is housed between crucible 5 and the furnace body wall, be provided with top heater 4 between the periphery of crucible 5 and the heat-insulation layer, the bottom of body of heater 2 is provided with out the fire door 7 of pipe, between fire door 7 and the crucible bottom is shaping area 1, is provided with second heating apparatus 6 at shaping area 1.Outside fire door 7, be provided with air-introduced machine structure 8.
The heater of bottom second heating apparatus 6 is to pass through copper electrode, insulating flange, the electrode pressing plate is mounted on the bottom of body of heater. and through the molybdenum supporting mass, aluminium oxide cradle adjustment level places among the body of heater, and the heater and the zirconia of easy conductive are at high temperature isolated with the aluminium oxide cover, in case the puncture of secondary heater and body of heater causes short circuit during high temperature. the adjustment of heater power is by realizing with supporting single-phase stokehold transformer and the SCR control module of secondary heater. control the size of its heating power by regulating control module, and then the temperature that realizes regulating shaping district, quartz ampoule continuous induction melting furnace bottom, and make the former size of certain deisgn product, the cooperation of the stream material mouthful size and the district's temperature that is shaped reaches best operating point, makes quartz ampoule amount and quality reach the optimum state of design.
Once heat with rod or net as the heating carrier on top, the bottom post bake with tungsten opening ring bodies as heating carrier.Power supply adopts the transformer supply of single-phase 40KW stokehold.The power of second heating apparatus accounts for the 10-15% of general power.Its equipment general power uses power to remain basically stable a little more than original device.The bottom post bake is in power supply state all the time at quartz ampoule continuous induction melting furnace duration of work, can adjust at any time according to the temperature requirement in quartz ampoule shaping district.Thermal treatment zone altitude range accounts for about 10% of total thermal treatment zone altitude range.
Claims (2)
1. quartz ampoule continuous induction melting furnace with bottom second heating apparatus, comprise body of heater and be located at the interior crucible of body of heater, between crucible and the furnace body wall heat-insulation layer is housed, be provided with the top heater between the periphery of crucible and the heat-insulation layer, the bottom of body of heater is provided with out the fire door of pipe, between fire door and the crucible bottom is shaping area, it is characterized in that: be provided with second heating apparatus at shaping area.
2. the quartz ampoule continuous induction melting furnace with bottom second heating apparatus according to claim 1 is characterized in that: be provided with the air-introduced machine structure outside fire door.
