Description
Technical field
The utility model relates to glass manufacturing area, is specifically related to a kind of electrically heated supply channel of glass furnace.
Background technology
During glasswork was produced, the main effect of supply channel was that the fused glass metal is transported to feeding machine.In this process, must constantly heat glass metal, so that glass metal keeps temperature required when arriving feeding machine, guarantee the glasswork quality of producing.
Conventional at present supply channel adopts diesel oil, liquefied gas or Sweet natural gas, coke-oven gas to heat more, because the supply channel space is less, causes fuel combustion insufficient, adds thermally labile, and the impurity in the gas can enter glass metal, causes the product quality instability; And thermo-efficiency is low, and exhaust gas emission is arranged.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of improvement of glass furnace supply channel is provided, and this supply channel should have thermo-efficiency height, temperature-stable, characteristic of simple structure.
The utility model can be achieved through the following technical solutions:
Glass furnace electrically heated supply channel comprises a horizontally disposed charging tank, and the external packets of charging tank is wrapped with thermal insulation layer and flame retardant coating; It is characterized in that: the top of described charging tank is provided with at least two heating zone, horizontally disposed by the some respectively and electric heating tube that be parallel to each other in each heating zone is formed, all electrothermal tubes are powered by furnace transformer, and this furnace transformer is connected with a temperature-control device.
Described temperature-control device comprises at least two thermopairs, and two thermopairs insert two heating zone respectively, and thermopair is connected with temp controlled meter, controllable silicon controller, and described furnace transformer is connected the control end of controllable silicon controller.
Described electric heating tube is a globars.
Use principle of the present utility model is:
Two heating zone of the present utility model adopt some globarss that glass metal is carried out radiation heating, thermopair detects the temperature in the supply channel, when the temperature of glass metal reaches preset value, thermopair feeds back signal to controllable silicon controller, controllable silicon controller sends instruction, and furnace transformer stops to power to globars; When the temperature of glass metal was reduced to another preset value, thermopair fed back signal to controllable silicon controller, and furnace transformer continues to the globars power supply glass metal to be heated.
The beneficial effects of the utility model are: the utility model adopts globars that charging tank is heated, the energy source clean, there is not waste gas to produce, and thermo-efficiency height, temperature-stable, can not produce the contaminating impurity glass metal, the quality product of producing is guaranteed, and of the present utility model simple in structure, and cost of manufacture is lower.
