Description
Technical field
The present invention relates to a kind of drying kiln, be specifically related to a kind of double-deck drying kiln, the double-deck drying kiln of particularly a kind of external-heat.
Background technology
The outmoded backwardness of drying materials equipment in the industries such as building materials, cement, metallurgical smelting still adopts rotary dryer at present, and it is horizontal, and floor space is big, power draw is big, energy consumption is high, smoke contamination is serious.Also occurred some vertical dry kilns in recent years, its structure mainly comprises vertical furnace body, blower fan, exhaust column, combustion chamber and guillotine, though it reduced occupation of land, energy consumption decreases; But still there is following tangible deficiency in it: at first be its guillotine, the guillotine of existing vertical drying kiln is a taper revolving body, and the resistance that dams is little; Can not be absorbed to each guillotine place section heat absorption by material; Return again but directly rise to the top material spreading cone, cause the top heat higher, may cause spontaneous combustion like oven dry coal; As dry clay etc. and then can lump, cause frame.Next is that its heat-insulating property is bad, the vertical drying kiln that uses at present outside no heat-insulation layer, the big area of the temperature difference in the winter time; Furnace body wall is prone to dewfall and the downward flowing water along the furnace wall; Material can not all be dried, and the body of heater surface radiating is fast, adds tens suction opeings in furnace wall and directly sucks exhaust duct; Cause heat loss big, the thermal efficiency is low.Secondly be that doing of material baking is wet uneven again; Existing vertical dry kiln periphery has 4 to 6 road gland steam exhausters from top to bottom, opens suction opeing at each guillotine correspondence position, and the oven dry material that unloads is at the vertical place that does not have suction opeing; Water vapour in the material is not discharged, and the material that unloads is done wet uneven.
Therefore, provide a kind of simple in structure, easy to operate, good drying effect, energy-conserving and environment-protective are heated evenly, high efficiency, the thermal efficiency is high, and the double-deck drying kiln of the uniform external-heat of drying materials has vast market prospect.
Summary of the invention
To the deficiency of prior art, the present invention provides a kind of simple in structure, easy to operate, good drying effect, energy-conserving and environment-protective, is heated evenly, high efficiency, high, the double-deck drying kiln of the uniform external-heat of drying materials of the thermal efficiency.
Technical scheme of the present invention is achieved in that the double-deck drying kiln of a kind of external-heat, comprises being arranged on advancing burner, being fixedly mounted on gear ring and roller on the urceolus of urceolus both sides, and described urceolus set inside has inner core; Be installed with away the material helical blade on the inner core, walk to expect that the inner core between the blade of helical blade is provided with flitch, the inner core set inside has and crosses the interior storehouse of overdoing that burner is connected; Cross burner and advance burner and be connected; Between inner core and urceolus, be provided with dram, dram one side is connected with discharging opening, and opposite side is connected with the feeding cylinder that offers feed hopper; The feeding cylinder set inside has feed auger; Feed auger is connected with reductor, and reductor is connected with motor, between dram and urceolus, be provided with overdo outside the storehouse; The storehouse is connected with the outer storehouse of overdoing in overdoing, and the outer storehouse of overdoing is connected with crater.
Described dram is connected with the dedusting exhaust chamber through pipeline, and the dedusting exhaust chamber is connected with the dedusting discharge duct.
Be provided with lifting blade between described inner core and the dram.
The storehouse is connected with the outer storehouse of overdoing through crossing quirk in described the overdoing.
The present invention has following good effect: at first, the urceolus set inside has inner core, is installed with away the material helical blade on the inner core, walks to expect that the inner core between the blade of helical blade is provided with flitch; The inner core set inside has and crosses the interior storehouse of overdoing that burner is connected, and crosses burner and advances burner and be connected, and between inner core and urceolus, is provided with dram, and dram one side is connected with discharging opening; Opposite side is connected with the feeding cylinder that offers feed hopper, and the feeding cylinder set inside has feed auger, and feed auger is connected with reductor; Reductor is connected with motor, between dram and urceolus, be provided with overdo outside the storehouse, overdo in the storehouse be connected with the outer storehouse of overdoing; The outer storehouse of overdoing is connected with crater, after feeding fire, in material the overdoing in inner dram the storehouse with overdo outside dry rapidly under the two-sided heats in storehouse; Interior heat acts on outer heat simultaneously, good drying effect, and heat utilization efficiency is high; Improve operating efficiency greatly, improved energy utilization rate, played the good effect of energy-conserving and environment-protective; Secondly; Dram is connected with the dedusting exhaust chamber through pipeline; The dedusting exhaust chamber is connected with the dedusting discharge duct, and in oven dry, material dust and steam are rejected to the external world through the dedusting discharge duct; The smooth discharge of steam and dust when having guaranteed the oven dry operation has guaranteed material efficiently radiates heat dehumidifying in drying course simultaneously; In addition; Be provided with lifting blade between inner core and the dram; Walk to expect that the inner core between the blade of helical blade is provided with flitch, in the cylindrical shell rotation, through lifting blade material is sent to and hard-wiredly on the inner core walks to expect helical blade; Last flitch will drive in the cylindrical shell rotation because of the material that dram bottom is fallen in the self gravitation effect above the dram; Through the effect of walking to expect helical blade material is advanced to the discharging opening direction simultaneously, material is heated evenly, and has improved operating efficiency greatly.
