Described preheating zone, which isolates wicket 7 and clinkering zone with clinkering zone and isolates wicket 8 with cooling zone, makes the gas in tunnel cave Stream is moved according to vertical direction.
It is lifting valve mechanism that described preheating zone, which isolates wicket 7 and clinkering zone with clinkering zone and isolates wicket 8 with cooling zone, Positioned at 1100 DEG C or so of preheating zone and cooling zone.
Described cooling blower 4, combustion gas blower fan 11 and flue gas blower fan 17 vertically moves the air-flow in tunnel cave.
Entrance wicket 1 is located at the porch of tunnel cave, is closed after kiln car 6 and after burning till adobe 5 and fully entering, exports kiln Door 3 is located at the exit of tunnel cave, is opened after burning till adobe 5 and burning till, kiln car 6 is released.
Cooling blower 4, the adobe that cooling is burnt till by clinkering zone high temperature are opened when kiln starts to burn till, and determines air-flow side To vertically moving air-flow.The block pattern row pattern of magnesia refractories adobe 5 to be burnt till is on kiln car 6, with kiln car 6 according to certain Speed is moved in tunnel cave.After adobe fully enter start to burn till after close preheating zone isolate wicket 7 with clinkering zone, will preheat Band is isolated with clinkering zone, and air-flow is moved according to vertical direction.After adobe fully enter start to burn till after close clinkering zone with Cooling zone isolates wicket 8, clinkering zone is isolated with cooling zone, and air-flow is moved according to vertical direction.
When starting to burn till, decompression stomata 9 plays suction function in reduction kiln, and balanced gas channel 10 makes uprush equal Weighing apparatus is moved horizontally, and opens combustion gas blower fan 11 and fuel gas is blasted into clinkering zone, and determines airflow direction, vertically moves air-flow, Open flue gas blower fan 17 to take the flue gas of generation out of, and determine airflow direction, vertically move air-flow.
As illustrated, the present invention uses air current sealed mode, after beginning is burnt till, arrow 12 is cooling at outlet wicket 3 Airflow direction, the airflow direction of cooling zone, arrow 13 is the airflow direction that clinkering zone is isolated with cooling zone at wicket 8, cooling zone Airflow direction;Arrow 14 is clinkering zone kiln top airflow direction, and the airflow direction of clinkering zone, arrow 15 is clinkering zone kiln bottom air-flow Direction, the airflow direction of clinkering zone;Arrow 16 is porch airflow direction, the airflow direction of preheating zone.
A kind of uprush refractory material burns till the process for calcining of tunnel cave, and this method at least comprises the following steps:
Step 1:Dry kiln.
Step 2:Normal product is burnt till.
In described step 1, in addition to as follows step by step:
Step 1.1:Adobe 5 to be burnt till is put on kiln car 6, is pushed into through entrance wicket 1 in tunnel cave, and close 1-4 entrances Wicket 1.
Step 1.2:Right gas, combustion air are lighted by the burner of clinkering zone, by predetermined heating curve, kiln is dried.
Step 1.3:Flue gas blower fan 17, cooling blower 4 are in regulation and control state, after kiln temperature reaches predetermined curve, dry kiln knot Beam, into normal production status.
