Description
Technical field
The present invention relates to a kind of furnace construction and the method for cloisonne brick thereof.
Background technology
There is the long history firing fragment of brick and pottery in China, and Qin brick and Han tile also has the symbol of ceramic Zeng Zuowei China, has far-reaching influence to the world, and fired brick and ceramic are also to be widely used and essential in the middle of present productive life.The common feature of these burned products one needs to sinter in furnace equipment exactly, and the development and progress of kiln is directly connected to the quality of the product of burning till, output.
The general sintering process of now general fragment of brick is adobe inside and outside grilled thoroughly with big fire, then stop working, and kiln and brick are cooled naturally.Now, kiln air flow leads to, and oxygen is sufficient, defines a good oxidation environment, makes the ferro element in adobe be oxidized to di-iron trioxide; Because di-iron trioxide is red, so also will take on a red color, this is general common brick treatment process.If after adobe is grilled thoroughly, continuous trickle in kiln, now, because kiln temperature is very high, water becomes water vapour very soon, will stop the circulation of air, make the environment forming an anoxic in kiln, the di-iron trioxide in brick is just reduced into ferrous oxide, and is present in brick; Because ferrous oxide is caesious, thus brick will be cinerous, and this is general blue bricks treatment process.As can be seen here, blue bricks process is higher to technological requirement, also has higher market value.
But traditional blue bricks kiln is generally adopted and come in two ways to carry out anoxic cooling down to the burned product in kiln body and kiln after having fired, one is adopt pump to be pumped into by water in kiln body, and two is the extensive modes adopting flood irrigation of watering to kiln body.Because kiln temperature is higher, usually all remain on 800 ~ 900 DEG C, as adopted the mode pumped into, cold water is when through kiln body, meeting instant vaporization, cause pressure to rise sharply, cold water can flow backwards, and so just needing more powerful pump that intake pressure is increased could pump in kiln body by cold water, virtually add huge production cost, and the cold water pumped into is easy to produce bubble, and then brings more air into, is unfavorable for brick firing; As adopted the mode of flood irrigation of watering directly to kiln body, because the most of cold water watered on kiln body is all evaporated, can only can soak infiltration kiln body wall and enter in kiln body by little a part of cold water, innermost layer wall and burned product only can be relied on to carry out heat exchange, energy waste is very serious, and this type of cooling, at least need the time of more than 5 days, when adding that cold water soaks the nexine wall penetrating into kiln body, temperature has increased many, therefore quite low with the heat exchange efficiency of burned product, the utilization rate of cold water is in urgent need to be improved.
Certainly, also someone attempts adopting other modes to carry out air-isolation cooling, in kiln, pass into the mode such as inert gas, nitrogen as taked and discharge air body, but because the gas price such as inert gas, nitrogen is expensive, production cost is high, and tool easily impacts environment, well production cost can not be reduced.
Summary of the invention
For above-mentioned deficiency, one of the object of the invention is to provide one directly can carry out water cooling, and the furnace construction that cool time is short, burned product qualification rate is high.
Above object implementation is:
One directly can carry out water-cooled kiln, comprising:
Kiln body, is the cavity of the relative closure that is enclosed by end face, Yao Bi, wicket and chassis, only between kiln wall and kiln car, leaves gap, for discharging excessive gas; Burner, is arranged on wicket, for heating burned product; Cold water bucket, runs through and arranges on end face or kiln wall, and the one side that described cold water bucket is positioned at kiln intracoelomic cavity is offered to a discharging device; Temperature measuring equipment, is arranged on kiln intracoelomic cavity, for measuring the temperature in kiln body;
Further, described discharging device is cooling tube, and described cooling tube one end is directly communicated with described cold water bucket or cools feed pipe with the external world after running through cold water bucket and is communicated with, and can be recirculated water, be in lower temperature all the time to keep cold water in cold water bucket.The other end is arranged in the inner chamber of kiln body, and is provided with one or more steam pressure release aperture thereon, is positioned at one or more steam pressure release aperture of end and the outer surface of cold water bucket is circumscribed structure.When cold water enters in kiln intracoelomic cavity, because the temperature in kiln is usually up to more than 800 degree, these cold water just entered in kiln can by instant vaporization, and now these steam pressure release aperture, be particularly that circumscribed steam pressure release aperture can carry out moment pressure release to these steam with the outer surface of cold water bucket, prevent cold water from flowing backwards because the pressure that is subject to is too large, the kiln intracoelomic cavity that naturally flows into effectively realizing cold water carries out heat exchange, burned product being cooled, without the need to additionally applying pressure, saving cost.
Be further, described cooling tube comprises VERTICAL TUBE and horizontal tube, wherein, the upper end of VERTICAL TUBE is communicated with cold water bucket or runs through connection, lower end is communicated with horizontal tube, horizontal tube extends layout along the inwall of kiln body, when cold water enters into kiln intracoelomic cavity, be subject to the high temperature of degree more than 800, can by instant vaporization, the extension of VERTICAL TUBE and horizontal tube is arranged, these steam can be incorporated into each position in kiln inner chamber, make chilling temperature in kiln intracoelomic cavity and cooling velocity more evenly and balance, improve product qualified rate and quality further.
Further, described cooling tube is arranged in many rows or multiple row in kiln intracoelomic cavity, adds comparatively uniformly better to realize cooling water, makes heat exchange between the burned product in kiln intracoelomic cavity and cooling water (water vapour) more even, improves quality of finished.
Further, described cooling tube arranges a Water flow adjusting valve on the leading portion entering kiln inner chamber, is convenient to the flow from external control cooling water.
Further, described temperature measuring equipment is temperature sensor.
Further, wicket is provided with peephole, the basic condition of burned product in kiln can be observed by peephole.
Another object of the present invention is to provide a kind of method utilizing above-mentioned furnace construction brick firing.
Another object of the present invention is realized by following two kinds of technical schemes:
The method of the first cloisonne brick, comprises the steps:
