Description
Technical field
The utility model relates to the drying oven field realizing granule materials and dry, and particularly relates to the energy-saving drying oven of one of the drying materials such as cement raw material, breeze, slag.
Background technology
The drying oven that current China granular material is dried mainly contains oil oven, steam stove and coal furnace, due to domestic rich coal resources, so in cement raw material, breeze, slag industry mainly based on coal furnace, using maximum is the combination of coal furnace and rotary drying machine, this combination has equipment maturation, production capacity is high, operate stable feature, but at present ubiquity drying oven tail and rotary drying machine feed end temperature is too high, thermal waste serious, maintenance is frequent, service life is short feature.
Utility model content
According to above deficiency of the prior art, problem to be solved in the utility model is:
A kind of energy-saving drying oven is provided, make its drying oven tail and rotary drying machine feed end temperature is controlled well, heat energy utilization is abundant, easy to maintenance, long service life.
The utility model solves the technical scheme that its technical problem adopts:
Energy-saving drying oven comprises body of heater and hyperthermia drying room two parts, it is characterized in that described body of heater is cuboid, body of heater shell 2 is low carbon steel plate, inside is built into wall body structure for refractory brick 11, heat insulating pearlite material 15 is filled with between body of heater shell 2 and refractory brick 11, body of heater top is arch firebrick structure, the coal feeding pipe road that taper shape enters coal hopper 1 is provided with in leading portion body of wall, fire grate 6 is arranged at bottom, it is centrifugal fan 17 below fire grate 6, the air quantity of centrifugal fan 17, blast passes through VFC, centrifugal fan 17 and drying oven entirety are all fixed on concrete 14, the fire resisting wall 7 and fire resisting wall air outlet 8 be built into refractory brick at the end of body of heater, end lower concrete 14 has ashes discharge port 3, convenient for discharging ash.
Described hyperthermia drying room is the cuboid of firebrick structure, entirety is fixed on concrete 14, position, upper end semicircular arc structure, semicircular arc structure has two charging apertures 4 and an adjusting valve 5, the inner equal flitch 10 of Alloys Casting for changing, equal flitch 10 is fixed on the equal flitch be integrated with refractory brickwork and supports 16, the side body of wall of close drying oven and drying oven are built and are integrated, and have square high temperature drying chamber air inlet 9, the lower end of hyperthermia drying room arranges one above for square, side is the rotary drying machine feed hopper 12 of the circular low-carbon steel material mated with rotary drying machine 13.
The beneficial effect that the utility model novel energy-saving drying oven has is: by the setting of drying oven and hyperthermia drying room, when not increasing power, make use of high temperature heat between drying oven tail and rotary drying machine feed end fully, through testing the combination of coal furnace and rotary drying machine on year-on-year basis, heat utilization rate improves more than 25%, while carrying out material fully drying, reduce stove tail and the temperature entering rotary drying machine, make maintenance of equipment simple, long service life.
