Description
Technical field
The utility model belongs to the manufacturing technology field of float glass, is specifically related to a kind of melting furnaces port of export cooling end glass metal register.
Background technology
The melting furnaces of float glass are by melting end, card neck, cooling end composition, the function of cooling end is that the quality of glass metal and temperature are adjusted to suitable scope, at present domestic is to pass into cooling air at cooling end to reach glass metal cooling, thereby control temperature of glass liquid at an OK range, in general while producing white glass, the cooling of major control glass metal, do not need to heat up, but in the time that needs are produced coloured glass or ultra-thin glass, due to coloured glass, ultra-thin glass forming requirements is higher, therefore must heat up to glass metal at cooling end, make the temperature of glass metal reach OK range, thereby meet the quality requirement of glass ware forming. therefore need the device that also can heat up of can lowering the temperature.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to propose a kind of melting furnaces port of export cooling end glass metal register.
The utility model adopts following technical scheme for completing above-mentioned purpose:
A kind of melting furnaces port of export cooling end glass metal register, described glass metal register is arranged on the front portion of melting furnaces port of export cooling end; Described glass metal register has to heat the burning rifle of melting furnaces port of export cooling end glass metal; The outlet of described burning rifle is positioned at melting furnaces port of export cooling end; The front end of described burning rifle is provided with and the air inlet of the rifle that burns, the valve body that air inlet is communicated with; In described valve body, there is the inlet channel being communicated with the air inlet of burning rifle and the air intake passage being communicated with the air inlet of burning rifle; The other end of described inlet channel is connected with natural gas line, and is provided with safety cut-off valve between inlet channel and natural gas line; The other end of described air intake passage is connected with blower fan, and between air intake passage and blower fan, electric control valve is set; Described electric control valve, safety cut-off valve are all connected with DCS system; Described glass metal register also include in order to the temperature of glass metal is detected at thermocouple; Described thermocouple is connected with described DCS system; Described burning rifle is connected with the air intake passage on valve body as the air intake passage of cooling air, and by the outlet of burning rifle, cooling air is sent into melting furnaces port of export cooling end; The air intake passage of described burning rifle is connected with the air intake passage on valve body, the inlet channel of burning rifle is sent natural gas into burning rifle, make natural gas inject flames into melting furnaces port of export cooling end in the combustion-supporting lower burning of cooling air and by the outlet of burning rifle, thus heating glass metal.
A kind of melting furnaces port of export cooling end glass metal register the utility model proposes, adopt technique scheme, melting furnaces port of export cooling end can be heated or cooled glass liquid according to the needs of institute's processed glass, thereby control temperature of glass liquid at an OK range, meet the quality requirement of glass, and have simple in structure, the feature easily realizing.

Detailed description of the invention
With specific embodiment, the utility model is illustrated by reference to the accompanying drawings:
As shown in Figure 1, a kind of melting furnaces port of export cooling end glass metal register, described glass metal register is arranged on the front portion of melting furnaces port of export cooling end 10; Described glass metal register has to heat the burning rifle 15 of melting furnaces port of export cooling end glass metal; The outlet 8 of described burning rifle 15 is positioned at melting furnaces port of export cooling end 10; The front end of described burning rifle 15 is provided with and the air inlet of the rifle that burns, the valve body 5 that air inlet is communicated with; In described valve body 5, there is the inlet channel 4 being communicated with the air inlet of burning rifle and the air intake passage 1 being communicated with the air inlet of burning rifle; The other end of described inlet channel 4 is connected with natural gas line, and is provided with safety cut-off valve 3 between inlet channel 4 and natural gas line; The other end of described air intake passage 1 is connected with blower fan 13, and between air intake passage 1 and blower fan 13, electric control valve 2 is set; Described electric control valve 2, safety cut-off valve equal 3 is connected with DCS system 14; Described glass metal register also include in order to the temperature of glass metal is detected at thermocouple 11; Described thermocouple 11 is connected with described DCS system 14; Described DCS system 14 is ripe technology in prior art, does not do too much explanation at this; In the time that melting furnaces port of export cooling end 10 need to be lowered the temperature, described safety cut-off valve 3 is closed, described burning rifle 15 is connected with the air intake passage 1 on valve body as the air intake passage of cooling air, and by the outlet 8 of burning rifle, cooling air is sent into melting furnaces port of export cooling end 10; In the time that melting furnaces port of export cooling end need to heat up, described safety cut-off valve 3 is opened, by the inlet channel 4 on valve body 5, natural gas is sent into burning rifle, and it is combustion-supporting to introduce cooling air by the air intake passage on valve body, make natural gas inject flames into melting furnaces port of export cooling end in the combustion-supporting lower burning of cooling air and by the outlet of burning rifle, thus heating glass metal.
In the time of production common white glass, melting furnaces port of export cooling end 10 needs cooling, DCS system and thermocouple 11 joint controls, adjust the air quantity of blower fan by adjusting the frequency of motor inverter of blower fan, now cold wind enters in valve body 5 by cooling air air inlet 1, then enters melting furnaces cooling end 10 by air outlet 8, reaches the object that glass metal 12 is lowered the temperature, now the closed condition signal of natural gas safety cut-off valve 3 is passed to DCS system, and natural gas air inlet 4 is in closed condition.
When in the time producing coloured glass, ultra-thin glass, cooling end need to heat up, the burning of natural gas needs cooling air combustion-supporting, cooling air regulates by the size of the motorized adjustment valve opening 2 on air inlet airduct, and now the frequency of the frequency converter of blower fan is a definite value, does not participate in adjusting. The size of natural gas tolerance is to be realized by ratio adjusting valve 7 before the rifle of each rifle of air quantity control of dilution wind blower fan. Now the opening signal of natural gas safety cut-off valve 3 is passed to DCS system, natural gas enters air inlet 4 by pipeline, again by valve body 5 with enter rifle before ratio adjusting valve 7 enter melting furnaces cooling end from gas outlet 9 after mixing with cooling air, the heat producing by burning heats up glass metal 12, and now cooling air air inlet is in closed condition.
