Description
Technical field
Kiln manufacturing technology field is the utility model is related to, more particularly, to a kind of kiln roof construction and kiln.
Background technology
Kiln be built into refractory material and the equipment to burnt product, be pottery art shaping in indispensable facility.People
The ceramics of up to ten thousand years of class, which are burnt, makes history, have accumulated and abundant makes kiln pattern and experience.From the outdoor burnt in a heap, digging in the ground of primitive society
Hole, which is built, burns steamed bun shape liter flame circular kiln, half downdraf horse shoe flame furnace, half way up the mountain dragon kiln, oval kiln, then arrives Indoor Air kiln, electricity now
Kiln etc., kiln science and technology is in continuous improvement, but the kiln top of kiln is mostly vault or couter-ceiling at present.
However, since existing kiln top is mostly single vault or is couter-ceiling, and arch is in the width of kiln, because
And make it that the hot wind in kiln is laminar state, the hot wind of laminar condition can make the hot wind that the hot wind that upper strata is flowed is flowed with lower floor
Between produce temperature difference, which can then be transferred on the product heated in kiln, so as to cause the product cross section temperature difference, and
The temperature difference can influence the quality of product.
To sum up, how to overcome the above-mentioned technological deficiency on existing kiln top is that those skilled in the art's technology urgently to be resolved hurrily is asked
Topic.
Utility model content
The purpose of this utility model is to provide a kind of kiln roof construction, is made with solving kiln roof construction existing in the prior art
Obtain the technical problem that the quality of product declines.
