Abstract
The invention discloses a quartz continuous-melting furnace, which consists of furnace and copple in the furnace, wherein the insulating layer is loaded between copple and furnace wall; the heating device is set between the copple periphery and insulating layer; the upper lid is placed on the furnace with through-out hole in the middle; one small lid is set on the through-out hole; the bottom of small lid possesses boss to mate sliding through-out hole; the sealing coil is set between boss periphery and through-out hole; the upper hole of copple connects boss of small lid; the lifting device is set between small lid and upper lid; 3-5 screw rods are fixed around small lid on the upper lid of lifting device, which loads planet lifting gear with big inner gear coil.
Description
Technical field
The present invention relates to a kind of silica glass production technology, what relate generally to is the continuous smelting production unit that is used for quartzy common tube, quartz pushrod and big specification silica tube.
Background technology
Being used at present all kinds of quartz glass tube production and the resistance heating continuous induction melting furnace of specification both at home and abroad all is to adopt the crucible that fixed fused quartz is housed.The heating element that the excircle of crucible has tungsten and molybdenum material to make, its common ground is that arbitrary cross section of heating element all equates, this shows that temperature that heating element in process of production sends is certain substantially in vertical distribution, can't adjust the longitudinal temperature of crucible.The production of quartz glass tube is in crucible and the process that goes out the mouth of pot moulding---melting zone---exhaust area---the shaping area several sections that is the preheating zone.When the quartz glass tube of production different varieties specification or bar, temperature index to whole process has different requirements, particularly the temperature requirement of shaping area is higher, as change heating element power and then can change the temperature of preheating zone, melting zone, exhaust area, thereby make the production of quartz glass tube or rod major defect occur.Before the cooling that stops production,, need heat, guarantee that crucible is harmless when cooling the silica glass fusing disengaging crucible on crucible top because silica glass is very big at its expansion coefficient difference of different temperature sections with crucible.What take at present is to add high-power raising heating element temperature, will just can finish in the suitable time simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is at the deficiencies in the prior art, has proposed a kind of novel quartz glass continuous induction melting furnace, and it can change the temperature of shaping area under the constant condition of total power.
The technical problem to be solved in the present invention is achieved through the following technical solutions, a kind of quartz continuous melting furnace, it comprises body of heater and is located at the intravital crucible of stove, between crucible and the furnace body wall thermal insulation layer is housed, be provided with heating unit between the periphery of crucible and the thermal insulation layer, loam cake is housed on the body of heater, be characterized in: have a through hole in the center of loam cake, a tegillum is housed on the through hole, the tegillum bottom is provided with the boss that is slidingly matched with through hole, between boss outer rim and the through hole sealing-ring is housed, the boss of the suitable for reading and tegillum of crucible is fixedlyed connected, and between tegillum and the loam cake lifting device is housed.
The technical problem to be solved in the present invention can also come further to realize by the following technical programs, described lifting device is vertically fixed with 3～5 screw mandrels last covering around tegillum, the planet lifter wheel is housed on the screw mandrel, the planet lifter wheel is equipped with big ring gear outward, and the lifter wheel top joins by surface bearing and tegillum.
The technical problem to be solved in the present invention can also come further to realize by the following technical programs, in the screw mandrel upper end set nut is housed.
The present invention compared with prior art, on cover tegillum be housed, crucible is fixedlyed connected with tegillum, tegillum with cover greatly between the lifting device that can make the stepless lifting of crucible is housed.Lifting device comprises fixedly little body of heater, elevating screw, ring gear, planet lifter wheel, sealing-ring, the pressure ring of crucible.Thereby change the moulding offset and reach the quartz glass tube of production different varieties and specification, excellent requirement from changing the shaping area temperature.Before the cooling that stops production, crucible is reduced, can guarantee that crucible is harmless when cooling with the silica glass fusing disengaging crucible on crucible top in very short time.
