Description
[technical field]
The utility model relates to drainage tube technical field of heating, relates in particular to a kind of glass melting furnace drainage tube heating unit.
[background technology]
In recent years, along with scientific and technological progress, the functional requirement of high-end electronic component is in continuous increase, and glass is as the starting material of manufacturing electronic component, and its specification of quality is also improving constantly.Manufacture electronic component use glass time, glass metal drainage tube is drawn glass metal from glass melting furnace, flow into corresponding die for molding.Glass metal drainage tube must, under the parcel of heating system, obtain enough heats, and the constant or slow decreasing of guarantee temperature of glass liquid, only maintains the good trickling of glass metal, could obtain best drainage discharging effect.
Traditional drainage tube heating system adopts Resistant heating mode, upper, middle and lower each six groups totally ten eight groups of resistance wires be wrapped in respectively on special porcelain rod, around being installed on around drainage tube.Because the surface temperature of resistive heater only has 1100-1200 ℃, arrive the temperature of drainage channel by air radiation 950-1050 ℃ of left and right, lower than temperature of fusion in the furnace hearth of some glass metal, so the situation that cutout is stopped up easily occurs some glass metals in the time flowing through drainage tube.
Require lower (about 1100 degree are following), the good glass metal of trickling property for melting temperature (Tm), original Resistant heating technology can complete the process of drainage heating discharging substantially.But for the glass metal that melting temperature (Tm) is had relatively high expectations (about 1100 degree more than), trickling property is poor, just more difficult smoothly and stablize drainage and heated discharging production process.So just caused production cycle lengthening, maintenance cost such as uprises at the disadvantageous effect.
[utility model content]
Technical problem to be solved in the utility model is: a kind of drainage delivery heating device of fusion cast glass tank furnace is provided, changes the loaded down with trivial details manufacturing process of original Resistant heating system, and improve Heating temperature, guarantee continuous draining heating discharging production process.
For addressing the above problem, the drainage delivery heating device of a kind of glass metal of the present utility model by the following technical solutions:
A kind of drainage delivery heating device of glass metal, it is characterized in that: include glass melting furnace 1, on glass melting furnace 1, be provided with liquid outlet 11, described liquid outlet 11 places are connected with the drainage tube 2 that glass metal is drawn from glass melting furnace, around drainage tube 2, be provided with the multiple globarss 3 for heating drainage tube 2 interior glass metals, the two ends of described globars 3 are provided with wire and are connected to power supply.
The drainage delivery heating device of a kind of glass metal as above, is characterized in that: on described glass melting furnace 1, be fixed with bracing frame 5, described globars 3 is placed on bracing frame 5.
The drainage delivery heating device of a kind of glass metal as above, it is characterized in that: support frame as described above 5 is provided with the relative refractory brick in forward and backward position 4, on described forward and backward two refractory brick 4, be respectively equipped with mounting groove 41 and forward and backward mounting groove 41 positions are relative, the forward and backward two ends of described globars 3 are placed in the mounting groove 41 of forward and backward two refractory brick 4.
The drainage delivery heating device of a kind of glass metal as above, is characterized in that: described globars 3 is evenly arranged in drainage tube 2 around.
The drainage delivery heating device of a kind of glass metal as above, is characterized in that: described drainage tube 2 two ends port calibers are less than interlude caliber.
The beneficial effects of the utility model are mainly: the glass metal drainage e Foerderanlage of this glass melting furnace adopts globars to heat, make the surface temperature of globars between 1350-1450 ℃, the temperature that can make to be radiated on drainage tube reaches 1100-1200 ℃, make glass metal in trickling process, can not solidify cutout, guarantee continual and steady the carrying out of production process, enhance productivity, guarantee quality product.In addition, the time that globars damages replacing only needed about 30 minutes, and changed the expense of globars lower than the expense of the whole resistance wires of replacing, and visible globars type of heating had both saved time and also reduced cost in maintenance.

[embodiment]
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in Figure 1 and Figure 2, a kind of drainage e Foerderanlage of glass metal, include glass melting furnace 1, on glass melting furnace 1, be provided with liquid outlet 11, described liquid outlet 11 places are connected with the drainage tube 2 that glass metal is drawn from glass melting furnace, are provided with the multiple globarss 3 for heating glass metal around drainage tube 2.
Drainage tube 2 one end are that glass metal import 21, the other end are glass metal outlet 22, described glass metal import 21 is connected to liquid outlet 11, described glass metal outlet 22 is connected to the mould device of glass metal moulding, and drainage tube 2 is less than the cylindric moulding of centre caliber for two ends caliber.Drainage tube 1 adopts refractory materials parcel, and glass metal, from import flows into, trickles and flows out from outlet in pipeline.Globars 3 is evenly arranged in drainage tube 1 around.The two ends of globars 3 are respectively equipped with the refractory brick 4 of clamping globars 3, and described refractory brick 3 is provided with mounting groove 41, and mounting groove 41 positions on two refractory brick 3 of front and back are relative, and the end of described globars 3 is installed in mounting groove 41.The two ends of globars 3 are provided with wire joint, are switched to power supply.On described glass melting furnace 1, be fixed with bracing frame 5, described refractory brick 4 is placed on bracing frame 5, and is clamped up and down.
Globars electrical heating element, is take silicon carbide as main raw material(s), through certain moulding process, a kind of non-metal electric heating element forming by high temperature sintering.Globars is in heating power process, and its resistivity is nonlinearities change along with the difference of temperature.The heating of the process that globars is heat energy by electric energy conversion and metallic resistance silk has essential difference.
