Description
Technical field
The present invention relates to a kind of heating furnace, especially a kind of tetrafluoro flange heating furnace with temperature controlling function.
Background technique
Four fluorine tube Lining Technology more common at present is to be packed into four fluorine tube in steel pipe that both ends are then passed through mold again
The technique for carrying out flange carries out lining operation.The predominantly straight fire of mode heated before flange to beaded tube end heats or salt
The mode of bath heating is heated.Straight fire heating carries out operation mainly by the operating experience of operator, is easy to overheat four occur
Fluorine local ageing cracking and the bad situation of heating temperature flange not in place.Heat-conducting oil heating there are inconvenient for operation, need by
Flange pipe is holded up to be placed in salt bath and be heated, if if while having water not have processing completely to easily cause the feelings that salt bath splashing is hurted sb.'s feelings in pipeline
Condition.And there are tube head position residual nitric acid sodium to clear up after technique flange, is coated with larger impact to rear process.
Utility model content
The technical problem to be solved by the present invention is to keep the heating of tetrafluoro tubing more uniform, make heating temperature is more accurate can
Control improves safety when worker operation.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions.
A kind of tetrafluoro flange heating furnace, including furnace body, burner and temperature device, the furnace body includes insulating layer, interior
Gallbladder, fire door and furnace wall, the fire door are installed on the furnace wall, and the insulating layer is covered on the outside of the furnace wall, the liner
It is placed in the furnace wall, the liner and the fire door form a cavity, and the temperature device includes thermometer probe, thermometer
Casing and temperature controller, one end of the thermometer probe stretch to the liner, the thermometer probe and the temperature
Controller signal is connected, and the thermometer boss is set in the thermometer probe, and the burner includes burner, wind
Door and fuel channel, the air door be mounted on the furnace wall, the burner is placed in the furnace wall, the fuel channel with
The burner is connected, and control valve, the control valve and the temperature controller signal are equipped on the fuel channel
It is connected.
Further, offer flue on the furnace wall, the flue and the liner and the furnace wall it
Between the space that is formed communicate.
Further, the liner is cone close to one end of the burner, and cone is uniformly heated, to make chamber
Intracorporal air themperature is more uniform, and the side of cone is inclined-plane, bigger compared to the area of plane, enhances heat convection and spoke
Penetrate heat exchange.In addition, the easier inclined-plane along cone of flue gas that burning generates flows upwards, convenient for being arranged by flue
Out.
Further, transported fuel can select combustion gas, fuel oil according to the actual situation in the fuel channel.
Further, burner described in the air door face makes the air entered by air door more fully burn.
Further, the furnace body is installed on the support.
The utility model has the advantages that (1), due to the hot-air and radiant heating method using controllable temperature, tetrafluoro tube head is heated
It is relatively uniform, and be not in aging or heating phenomenon not in place, it can be controlled with time quantization mode；
(2) due to using hot air, to flange pipeline by the way of traverse heating, more compared to salt bath heating
It is convenient；Splashing casualty accident will not be caused with the presence of a small amount of residual water simultaneously.Simultaneously because heating method is cleaner,
There is no adverse effect to the coating of rear process.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is this heating furnace structure schematic diagram.
Wherein: 1 insulating layer, 2 liners, 3 burners, 4 air doors, 5 thermometer boss, 6 flues, 7 fire doors, 8 control valves
Door, 9 supports, 10 furnace walls, 11 furnace bodies, 12 thermometer probes, 13 thermometer controllers, 14 burners, 15 temperature devices, 16
