Technical field
The utility model relates to a kind of continuous induction melting furnace, is specifically related to the many warm area heating continuous induction melting furnaces of a kind of production of quartz tubes, belongs to production of quartz tubes technical field.
Background technology
Existing quartz continuous melting furnace heating unit many employings external heat, is namely arranged heating unit, is heated by radiative transfer to crucible, make the quartz sand in crucible be melt into liquid state, and then draw shaping on crucible excircle.At present, heating unit is made up of molybdenum electrode and 64 molybdenum bars, is vertically evenly arranged in around tungsten crucible, is heated comparatively even in crucible.But after quartz sand enters crucible by filling tube, preheating, melting and exhaust moulding process need be carried out, for keeping the mobility of fluid, requiring that the temperature of melting zone is higher, for making the full and uniform fusing of quartz sand in crucible, heater power can be improved to improve Heating temperature, but temperature raising can make tektite sand viscosity in crucible reduce, thus crucible bottom discharging is too fast, the footpath of the silica tube causing fire door to pull out, rod and the controllability of wall thickness reduce, lack of homogeneity.And raw material vertically enters stove from opening for feed, can skewness, can not good thermally equivalent.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, feed distribution can be made even, and many warm areas heating system meets the requirement of crucible regional differing temps, makes heating material even, improves the quality of products.
For realizing above object, the utility model is achieved by the following technical programs:
A kind of many warm area heating continuous induction melting furnaces, comprise body of heater, bell, bell is provided with feed-pipe and nut, crucible is provided with in body of heater, heating unit is provided with outside crucible, crucible center is provided with core bar, material platform is connected with bottom core bar, core bar upper end is connected with the nut on bell by screw thread, it is characterized in that, crucible has three-decker, bottom is round platform, middle part is cylinder, top is back-off round platform, three layers of integrated smooth connection, and three layers of outside are equipped with main heating unit, work independently between each layer, additional thermal is also provided with in upper crucible, the raw material material-strewing device that described opening for feed connects is provided with on the top of crucible.
Described upper and lower part crucible diameter is equally large, 30-60mm larger than middle part crucible diameter, and the aspect ratio of upper, middle and lower crucible is 2:2:1.
Described crucible is surveyed main heating unit outward and is comprised electrode and heating rod molybdenum bar, and upper, middle and lower crucible is surveyed molybdenum bar outward and is spaced, and every number of layers is 64 groups.
Outside described upper, middle and lower crucible layer, main heating devices heat temperature range is respectively 0-2200 DEG C, 0-2500 DEG C, 0-2400 DEG C.
Described additional thermal comprises auxiliary electrode and additional hot pin, and auxiliary electrode rod is spirane structure.
Described material-strewing device is a regular polygon, and there is an extending shaft in direction, one, every bar edge, radially launches to surrounding.
The utility model is reasonable in design, multilayer temperature range is obtained by regulating the heating rod power of different layers, meet the temperature requirement of crucible regional, improve the quality of products, and by connecting material-strewing device at opening for feed, change the flow direction that input quartz raw material is vertical, make quartz raw material multi-faceted, enter melting zone uniformly and melt, reduce raw-material consumption.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, and to make those skilled in the art better can understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
The present embodiment provides a kind of many warm area heating continuous induction melting furnace, as Fig. 1, comprises 1, bell; 2, nut; 3, feed-pipe; 4, material-strewing device; 5, screw electrode; 6, the main heating unit in top; 7, the main heating unit in middle part; 8, core bar; 9, the main heating unit in bottom; 10, platform is expected; 11, dust exhaust; 12, chilled water unit; 13, insulating brick; 14, sand is incubated; 15, body of heater; 16, assisted heating device; 17, the parts such as crucible.Bell 1 is provided with feed-pipe 3 and nut 2, is provided with crucible 17 in body of heater 15, is provided with main heating unit 6,7,9 outside crucible 17, crucible 17 center is provided with core bar 8, regulate core bar 8 height by nut 2, be connected with material platform 10 bottom core bar 8, core bar 8 upper end connects bell 1.Crucible 17 has three-decker, bottom is round platform, middle part is cylinder, top is back-off round platform, three layers of integrated smooth connection, and the diameter of upper and lower part crucible is equally large, 30-60mm larger than middle part crucible diameter, the aspect ratio of upper, middle and lower portion crucible is 2:2:1.Three layers of outside are all equipped with main heating unit, and main heating unit comprises electrode and heating rod molybdenum bar, and upper, middle and lower crucible is surveyed molybdenum bar outward and is spaced, and every number of layers is 64 groups.Also be provided with additional thermal 16 in upper crucible, comprise auxiliary electrode and additional hot pin, auxiliary electrode rod is spirane structure.Be provided with the raw material material-strewing device 4 that described opening for feed connects on the top of crucible 17, its structure is a regular polygon, and there is an extending shaft in direction, one, every bar edge, radially launches to surrounding.
Quartz sand enters in crucible 17 by filling tube 3, in upper crucible, carry out preheating, enters middle crucible and carries out melting exhaust, then enters lower crucible melting clarification, pulls out shaping finally by material platform 10.Heated by main heating unit 6,7,9 pairs of crucible 17 peripheries, because middle crucible diameter is less than upper crucible diameter, therefore the material in the crucible of middle part is less than crucible, and the Heating temperature of middle part crucible is higher than upper crucible, thus ensure that the high-temperature of melting zone, and due to the internal diameter of middle part crucible little, horizontal heat transfer rate is fast, the stream of melting is heated evenly, avoids producing bubble, gas line.Lower crucible is material settling section, for trombone slide is prepared, though its diameter is slightly larger than middle crucible, but height is only the half of middle part crucible, its interval Heating temperature outline is lower than the interval Heating temperature of middle part crucible, and under this reduces high temperature, quartz sand viscosity diminishes, and discharging is too fast, the controllability of the quartz tube causing fire door to pull out and wall thickness reduces, lack of homogeneity.Additional thermal 16 can carry out interruption heating, and the contact area of spirane structure and material is larger, material in crucible is made to keep transverse temperature even, simultaneously, in the blowing out stage, by additional thermal 16, the silica powder fusing on body of heater 15 top is flowed out, avoids quartz to stick on crucible 17 inwall.
