Preferably, the rail is slidably connected with the coal-feeding tube.
Preferably, the exhaust opening is arranged on the top of the kiln body.
Preferably, the charging aperture is arranged far from the furnace wall of the kiln body of the exhaust opening side.
Preferably, the charging aperture is arranged at the top 1/3 or 1/4 of the kiln body.
Preferably, the slag notch is arranged on the furnace wall of the kiln body below the charging aperture.
Preferably, the inner furnace bottom of the kiln body is the high hemisphere face structure of the low surrounding in middle part or arc surface structure.
Preferably, the copper outlet is arranged on the furnace wall of the kiln body below the slag notch, and it is described go out
Copper mouth is connected with the inner furnace bottom of the kiln body.
Preferably, the surrounding outer rim at the inner furnace bottom is higher than middle part bottom surface 200mm～500mm.
(3) beneficial effect
A kind of packing device that the utility model is provided, it has advantages below：1st, the utility model is due to by exhaust opening
The top of kiln body is arranged on, charging aperture is arranged far from the furnace wall of the kiln body of exhaust opening side, therefore material
The pernicious gas that burning is produced will not be drawn in exhaust opening under suction function, can be prevented effectively from material advanced combustion and draw
The flue gas phenomenon not up to standard for rising.2nd, spray gun of the present utility model is the dual-purpose spray gun of kerosene, including rail, coal-feeding tube and fuel
Airduct, and rail is slidably connected in coal-feeding tube, therefore the position of rail, Jin Ercao can be as needed adjusted at work
Vertical spray gun changes two kinds of raw materials for production of fine coal and diesel oil, not only shortens the use changed the rifle time but also significantly improve spray gun
Life-span.3rd, the utility model is by inner furnace bottom due to being set to the high hemisphere face structure of the low surrounding in middle part or arc surface structure, because
This will not occur the situation that slag phase is mixed into copper liquid when copper liquid is discharged, it is ensured that product grade.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model kiln.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Example is used to illustrate the utility model, but is not limited to scope of the present utility model.
In description of the present utility model, it is to be understood that term " top ", " bottom ", " vertical ", " on ", D score
Deng instruction orientation or position relationship be based on orientation shown in the drawings or position relationship, be only for ease of describe the utility model
With simplify description, rather than indicate or infer the device or element of indication and must have specific orientation, for specific orientation structure
Make and operate, thus it is not intended that protecting the restriction of content to the utility model.
As shown in figure 1, the utility model includes the kiln body 1 being vertically arranged, on kiln body 1 exhaust opening is provided with
2nd, charging aperture 3, slag notch 4 and copper outlet 5；The dual-purpose spray gun 6 of kerosene is also vertically plugged with the inner chamber of kiln body 1, spray gun 6 is wrapped
