Description

A kind of kiln car down-draft kiln
Technical field
The utility model belongs to kiln technical field, and in particular to a kind of kiln car down-draft kiln.
Background technology
Ware be a kind of craftwork of long history, China in ancient times also because ceramics and well-known, the system of pottery art Raw material processing can be divided into order by making technique(Including matching mud and matching glaze), moulded pottery not yet put in a kiln to bake modeling system, assign glaze and calcining four big processes, wherein forging It is mostly important to burn supply and demand, and is easiest to the technique of failure, due to the limitation of Ancient Technology level, to the temperature of calcination process with The factor controllings such as time are not accurate enough, lead to the saying for " ten kilns nine not at " occur.This is just to kiln body and behaviour in calcination process Make personnel and propose very high requirement, down-draft kiln is a kind of relatively conventional kiln body.
Down-draft kiln is developed by a liter flame kiln, dome kiln, is that relatively long, wider one kind is used in China's ceramic industry Intermittent flame kiln, special flow of flue gas form are very suitable for the firing of ceramics with workflow.
Down-draft kiln is named according to the mobility status of kiln flame, and workflow is:The flame of fuel combustion is from combustion It burns after room enters firing firing chamber and rushes at vault upwards, folded down movement by the blocking of vault and the draft of kiln bottom flue, flow Material buttress through green body or the kiln furnitures for carrying green body, and green body is transferred thermal energy to, make green body that physical chemistry change occur when heated Change and be finally sintered, flame is then pooled to flue by the suction fire hole of kiln bottom, is discharged by chimney.Since flame flows in kiln Journey is flowed downward again after being upwardly into vault, therefore referred to as down-draft kiln.
The shaft kiln of down-draft kiln and vertical flame type(Furnace cupola)When compared to the distance for extending flowing of the flame in kiln and stop Between, so that the uniformity of kiln temperature field distribution is made moderate progress.Kiln body size is changeable, can be suitble to the burning of large-size ceramic green body At.So playing the effect of main heating equipment always in over one hundred year Production of Ceramics.
As application No. is CN96203998.5《Blower down-draft kiln》, use is exactly traditional structure, and down-draft kiln includes stove Body, bell, air inlet, fire bars, upper air duct, pad brick, lower air duct, chimney and partition wall, flame enters stove by upper air duct when burning Then thorax out enters chimney from lower air duct.
Application No. is CN201010206297.9's《A kind of down-draft kiln》, " when using this kiln, object is packed into burner hearth Material, when heated material, point former and later two half periods.First half cycle operating diagram is as indicated, the course of work of the kiln is:Kiln Material ... is packed into stove " all it is to take on that kiln is very inconvenient using traditional down-draft kiln structure, the ceramic of firing is easy It is inverted and damages because of transportation problem during taking on kiln, generate unnecessary loss.
Though the shaft kiln with vertical flame type of down-draft kiln simultaneously(Furnace cupola)Compared to extend flowing of the flame in kiln away from From and the residence time, so that the uniformity of kiln temperature field distribution is made moderate progress, but only one direction is heated above for ceramic, It is also possible to lead to the generation of defect ware because uneven heating is even.
Invention content
The utility model down-draft kiln of being solved takes on the problem that ceramic uneven heating is even in kiln inconvenience and kiln, provides A kind of kiln car down-draft kiln.
The utility model to solve the above problems, the technical solution used for:A kind of kiln car down-draft kiln, including be same as firing Combuster is arranged in the firing chamber of ceramics, the left and right sides of firing chamber or side, and firing chamber and combustion chamber share a kiln top, combustion chamber Side is provided with flame enrichment hole and flame-observing hole, is provided with firebreak between firing chamber and combustion chamber, at the top of firebreak with kiln top there are away from Enter firing chamber from combustion chamber from for flame, firing chamber bottom is provided with suction fire hole, inhales fire hole and is connected to flue, outside flue and firing chamber Chimney connection, be provided with wicket on front side of firing chamber, firing chamber bottom is provided with track, and the kiln car on track is enable to be passed in and out along track Firing chamber, kiln car include that end face is used to load the table top of ceramics on the car body for car body and setting, and is arranged in car body lower end and rail The wheel of road cooperation, car body middle part are provided with and inhale the matched kiln car suction fire hole of fire hole.
Further, car body upper surface is to the inclined circular cone in middle part or pyramidal surface, and surrounding higher position is connect with table top, Middle part lowest point is arranged kiln car and inhales fire hole.
Further, car body lower face is inhaled in kiln car is provided with downward convex edge around fire hole, reduce kiln car inhale fire hole with The gap of firing chamber bottom inhaled between fire hole.
Further, it is provided with protrusion at left and right sides of car body, corresponding recess is provided on firebreak.
Further, the center upper portion of firing chamber is provided with low inside and high outside wind shield, and firing chamber's side wall is arranged at kiln car There is high outside and low outside plate of calling prisoners in after letting them out for exercise.
Further, wind shield height is less than firebreak upper surface.
Further, it is provided with air hole on wind shield.
Further, kiln top is arch.
Further, it is provided with dust collection chamber below combustion chamber.
The utility model has technical effect that:
The kiln car down-draft kiln of the utility model makes to take on kiln efficiency significantly using kiln car by track into the structure of kiln discharge It improves, uses manpower and material resources sparingly, simultaneously because the stationarity of track, can also reduce ceramic during kiln discharge because transport is run Damage caused by winnowing with a dustpan;And it is provided with wind shield in firing chamber and plate of calling prisoners in after letting them out for exercise, flame is made to form a plurality of circulation canal in firing chamber, The comprehensive of ceramic is heated, so that it is heated evenly, the yield rate and condition of ceramic can be greatly improved, With preferable promotional value.
