Description
Technical field
The utility model relates to a kind of drying device, specifically is a kind of novel brown coal drying tunnel cave.
Background technology
Traditional handicraft is by the roller drying brown coal; cylinder itself and its dynamical system parts are numerous; and cylinder also will roll; so in the process of using, be worn; often breaking down needs shutdown maintenance; and then make brown coal drying cost height, since the restriction of cylinder itself, the inconvenient scale drying brown coal in enormous quantities of existing roller drying.
Tunnel cave generally is a long linear tunnel, and fixing wall and vault are arranged at its both sides and top, is moving kiln car on the track that lay the bottom.Combustion apparatus is located at the both sides, middle part of tunnel cave, constituted fixing high temperate zone--clinkering zone, the high-temperature flue gas that burning produces is under the effect of tunnel cave front end chimney or air-introduced machine, flow to the kiln hood direction along the tunnel, preheating enters the interior goods of kiln step by step simultaneously, and this section constituted the preheating zone of tunnel cave.Kiln tail at tunnel cave blasts cold wind, and back one section goods in the cooling tunnel kiln, the cold wind that blasts are flowed through goods and after being heated, being extracted out and send into the thermal source of drier as dried, and this section just constituted the salband of tunnel cave.
Place the saggar of the ceramic of packing on chassis, the inlet by the preheating zone pushes at leisure continuously, and is loaded with the chassis of the product of burning till, and just the outlet by salband is pushed out gradually.
Because be not subjected to the influence of rapid heat cycle in the kiln of tunnel cave, so kiln body long service life, durable in use, it is low to fire cost.In addition, tunnel cave itself is exactly the Thermal Equipment that a kind of modern continous way is burnt till, and can realize continuous large-scale production.
But,, be easy to putting and loading and unloading of ceramic product so kiln car is traditionally arranged to be unlimited sandwich construction because the existing tunnel kiln owner will be used for the baked for producing of ceramic product.Specific to brown coal, be the mud shape before its drying, be powdery, bulk after the drying, all do not have solid shape, can not as ceramic product, direct loading and unloading put, and brown coal itself are inflammable, can not directly contact with thermal source.
When traditional individual tunnel kiln is directly used in dry brown coal, coaling in the stem porch that the described kiln car that exports out from described tunnel cave afterbody needs to come back to described tunnel cave after unloading coal, could begin the drying operation of a new round then, in this process, the kiln car of heat is exposed in the air dissipated heat gradually, the time that exposes is long more, and it is many more that heat scatters and disappears, and makes that the heat utilization efficiency of whole described tunnel cave is low; In addition, described kiln car turns back to the inlet of tunnel cave from the outlet of described tunnel cave, can cause decrease in efficiency because sky be sailed and do a large amount of idle works.
