The utility model discloses structural design is ingenious, and thermal insulation performance is good, and the thermal efficiency is high, and the material is dried evenly fully.
Description
The utility model relates to a kind of dry kiln, particularly a kind of vertical dry kiln.
The outmoded backwardness of drying materials equipment in the industries such as building materials, cement, metallurgical smelting still adopts the rotary dryer of imitative Soviet Union since the establishment of the nation at present, and it is horizontal, and floor space is big, power draw is big, energy consumption is high, smoke contamination is serious.Some vertical dry kilns had also appearred in recent years, its structure mainly comprises the vertical furnace body, blower fan, exhaust column, combustion chamber and guillotine, though it has reduced occupation of land, energy consumption decreases, but still there is following tangible deficiency in it: the guillotine that at first is it, the guillotine of existing vertical drying kiln is a taper revolving body, 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, as dry coal and may cause spontaneous combustion, then can lump as oven dry clay etc., cause frame.Next is that its heat-insulating property is bad, the no heat-insulation layer in vertical drying kiln outside that uses at present, the big area of the temperature difference in the winter time, the easy dewfall of furnace body wall and along the furnace wall downward flowing water, 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 4-6 road gland steam exhauster 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.
The purpose of this utility model will provide a kind of good heat insulating exactly, the vertical dry kiln of circulation heating in thermal efficiency height, drying materials are double-deck uniformly.
The utility model adopts technical scheme as described below for achieving the above object: the vertical dry kiln of circulation heating comprises vertical furnace body, blower fan, exhaust column and guillotine in double-deck, the bottom combuster of vertical furnace body, guillotine is placed in the vertical furnace body end to endly, a sliding basin of discharging that is fixed on vertical furnace body inwall is all arranged at the top of each guillotine, and the sliding basin of discharging is an inverted cone of all not having the end up and down; The vertical furnace body is formed double-layer sleeve structure by inner core and urceolus, in, form heating chamber between the urceolus, have in the heating chamber and the corresponding annular row steam pipe of each guillotine, adjacent two annular row steam pipes intercept into less ring-shaped heating cavity with heating chamber, the top of annular row steam pipe all has a plurality of through holes that are connected with ring-shaped heating cavity, have the through hole that is connected with ring-shaped heating cavity on the exhaust column, all have the exhaust hole that a plurality of and corresponding annular row steam pipe is connected on the inner tube wall at the sliding basin of each discharging back side, because the effect of the sliding basin of discharging, material can not fall into the annular row steam pipe, the hot-air that has a water vapour then can be successfully enters the annular row steam pipe from the exhaust hole at the sliding basin of the discharging back side, and then enter ring-shaped heating cavity from the through hole on annular row steam pipe top, after exhaust column extract out, have a lot of heats because enter the air-flow of ring-shaped heating cavity, therefore can heat to inner core, thereby improve kiln body temperature inside, promptly effectively utilized heat energy, can stop the problem that inner tube wall drops down water again, in addition because the hole that open at the sliding basin back side is more, can siphon away at the water vapour in the material that each orientation falls, thereby can dry material equably.Its another characteristics are that the guillotine outer surface is provided with a plurality of fin, and the inside of guillotine also has a flow plug, and flow plug is an inverted taper type, and is fixed on gusset on the inwall of guillotine.In the process that material falls, fin is inserted in the material, thereby add thermal material more fully, flow plug has then increased the up resistance of thermal current, prolonged the time that thermal current contacts with guillotine, make guillotine can absorb heat fully, just the dry kiln temperature difference is up and down diminished, and then reach the purpose of full and uniform oven dry material like this.
Adopt the utility model structural design of said structure ingenious, good heat insulating, thermal efficiency height, drying materials are evenly abundant.
Below in conjunction with accompanying drawing the utility model is described in detail.
