Description
Technical field
The utility model relates to a kind of energy-saving and environment-friendly stuffing sand apparatus for baking, belong to the technology neck of stuffing sand roasting plant
Domain, the baking suitable for stuffing sand used in the great Bao hot repair workshop section of all electric furnaces, BOF steelmaking shop at present.
Background technique
Higher and higher to the requirement of big packet self-opening rate with the development of furnace outer refining technology, stuffing sand is in more stringent item
It works under part, cannot such as open and pour naturally, worker must not have to oxygen lance and the mouth of a river be blown boiled, and help is opened and poured.Big packet not from opening and
It carries out burning eye operation and has many problems appearance, be the personal safety of worker first, followed by oxygen blast bring molten steel oxidation, very
To the nonmetal inclusion that may cause slab.It is found through experiment that being caused not certainly when moisture content is greater than 0.5% in stuffing sand
The probability opened at least rises to 85%, therefore many steel mills use heated by gas hopper and stir-fry or directly draw gas pipe insertion
The method toasted in quicksand to it has good effect to moisture removal is removed although, but energy consumption is high for these methods, just in case coal gas
Fire extinguishing will cause the generation of personal coal gas injury accident；So now most of heated using thermocouple to remove stuffing sand
In moisture, but increase the consumption of electric energy.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of energy-saving and environment-friendly drainage for the above-mentioned prior art
Sand apparatus for baking can remove the moisture in stuffing sand and reduce power consumption using the recycling of electric furnace smelting waste heat.
A kind of the technical scheme in the invention for solving the above technical problem are as follows: energy-saving and environment-friendly stuffing sand baking dress
It sets, includes mainly baking oven, steam inlet duct, hollow circular-tube, steam outleting pipe and temperature controller, the baking oven is by shell and use
It being formed to place the interior room of baking material, the two forms interlayer, it is disposed with steam inlet duct and steam outleting pipe on the shell,
So that steam circulates in interlayer, the interior room is equipped with the hollow circular-tube being evenly arranged, and the hollow circular-tube is connected to interlayer, uses
Make steam in the guide pipe of interior room, the baking oven is equipped with temperature controller, for detecting and controlling stuffing sand baking temperature.
The hollow circular-tube is equipped with 4, and upper layer and lower layer are evenly arranged among interior room.
The steam inlet duct is arranged in the upper left side of shell, and position, the steam outleting pipe are arranged in the right side of shell rearward
Front position is leaned in lower section.
Compared with the prior art, the advantages of the utility model are: a kind of energy-saving and environment-friendly stuffing sand apparatus for baking, be
On the basis of guaranteeing stuffing sand cured effect, existing electric energy heating is substituted using the heat of electric furnace steel making waste heat recycling and is toasted,
Not only it can guarantee cured effect, but also power consumption can be reduced using the recycling of electric furnace smelting waste heat.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of energy-saving and environment-friendly stuffing sand apparatus for baking of the utility model embodiment；
1 steam inlet pipeline in figure, 2 temperature controllers, 3 hollow circular-tubes, 4 baking ovens, 5 interior rooms, 6 steam outleting pipe roads, outside 7
Shell.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown in Figure 1, the energy-saving and environment-friendly stuffing sand apparatus for baking of one of the present embodiment, mainly includes baking oven 4, steam
Air inlet pipe 1, hollow circular-tube 3, steam outleting pipe 6 and temperature controller 2, the baking oven 4 is by shell 7 and for placing baking material
Interior room 5 form, the two forms interlayer, steam inlet duct 1 and steam outleting pipe 6 is disposed on the shell 7, so that steam exists
It circulates in interlayer, 5 middle position of interior room is equipped with the hollow circular-tube 3 being evenly arranged, and the hollow circular-tube 3 is connected to interlayer,
As steam in the guide pipe of interior room 5, the baking oven 4 is equipped with temperature controller 2, for controlling stuffing sand baking temperature.
Upper layer and lower layer are evenly arranged 4 hollow circular-tubes 3 that diameter is 20mm in the interior room 5.
The steam inlet duct 1 is arranged in the upper left side of shell 7, and position, the inner diameter of steam inlet duct 1 are rearward
80mm, the circular section of steam inlet duct 1 are tangent with the left back vertical edges of baking oven 4 and upper left horizontal sides respectively；The steam outlet
Pipe 6 is arranged in the lower right of shell 7 by front position, and 6 inner diameter of steam outleting pipe is 50mm, the circular section of steam outleting pipe 6
It is tangent with the left back vertical edges of baking oven 4 and upper left horizontal sides respectively.
A kind of energy-saving and environment-friendly stuffing sand apparatus for baking, material is heat-resistance stainless steel；7 length and width of shell is
