Description

A kind of gangue tunnel cave is incubated segment structure
Technical field
The present invention relates to a kind of gangue tunnel cave insulation segment structure.
Background technology
Tunnel cave is usually a linear tunnel long, and fixed wall and vault, bottom paving are arranged at its both sides and top If track on run kiln car.Combustion apparatus is located at the middle part both sides of tunnel cave, constitutes fixed height temperate zone -- clinkering zone, The high-temperature flue gas for producing burn in the presence of tunnel cave front end chimney or air-introduced machine, is flowed to kiln hood direction along tunnel, together When preheat step by step into the product in kiln, this section constitutes the preheating zone of tunnel cave.Cold wind is blasted in the kiln tail of tunnel cave, Latter section of product in cooling tunnel kiln, the cold wind for blasting flows through product and after being heated, then extracts feeding drier out as dry The thermal source of dry green compact, this section just constitutes the cooling zone of tunnel cave.In existing refractory material production process, it is contemplated that cost Factor, mostly using gangue as combustion material, gangue is the solid waste of discharge during coal mining process and coal washing, is A kind of black gray expandable rock relatively low with a kind of phosphorus content of coal seam association in coalification course, harder than coal.Including tunnelling During digging gangue, mining process in the spoil that produces in top board, base plate and the interlayer and choose during coal washing Wash spoil.There is problems with during refractory material is fired in existing gangue tunnel cave insulation segment structure:Kiln body Heat insulation effect is poor, causes energy loss more, influences production cost and product quality;The kiln top suspending method of soaking zone is two The small suspended block of several piece is pressed from both sides between the big suspended block of block, recessed between size suspended block and protrusion part constitutes mutually an entirety, by gold Category suspension rod is hung on girder steel.This structure air-tightness is poor, and energy loss is more;Sand sealing groove structure setting is unreasonable, sand seal Groove cannot set height very high because of intensity limitation, cause the cut-off between the steel skirtboard of kiln car both sides and the sand sealing groove of side wall Effect is poor so that cold air is easily leaked in people's kiln, and hot gas is also easily spilt outside kiln, influences production cost and product quality.
The content of the invention
It is an object of the invention to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, Better heat preservation, the more preferable gangue tunnel cave insulation segment structure of air-tightness of suspended block.
