A kind of pair of heat source vertical type and use the drying system of this dryer
Technical field
The present invention relates to material drying machine field, particularly relate to a kind of pair of heat source vertical type and use the drying system of this dryer.
Background technology
Tower drier is also known as vertical drier, and its oven dry be widely used to material to the production processes such as moulded coal, cement, chemical fertilizer, has and take up an area little, small investment and stable feature.
Current tower drier comprises body of heater, and body of heater top has charging aperture, and bottom has discharge gate and hot wind inlet, and its madial wall is provided with lifting blade, in addition, is also provided with collet in body of heater, and the exhaust outlet of hot wind inlet passes in collet.In body of heater, hot blast is sent into by hot wind inlet during work, by corresponding conveying device, material to be dried is added body of heater from the charging aperture at body of heater top, enter the material of body of heater while slowly move down by gravity, while carry out heat exchange with the hot blast entering body of heater, finally reach the object of oven dry, the hot blast carrying out heat exchange with material is discharged outside body of heater from the exhaust outlet body of heater.
Above from its operation principle, thermal source is one of main factor affecting tower drier drying efficiency, but, in actual production process, be have certain requirement to the air quantity of the hot blast passed in tower drier, and current tower drier is all dried material by hot blast, in this case, in order to the dry requirement of material of can trying one's best, can only be reduce the flowing velocity of material in body of heater, this obviously limits the drying efficiency of tower drier.
Summary of the invention
The object of the present invention is to provide a kind of two heat source vertical type, to improve the drying efficiency of existing tower drier.
Meanwhile, the present invention also aims to provide the drying materials system using above-mentioned dryer.
In order to solve the problem, two heat source vertical type is by the following technical solutions: two heat source vertical type, comprise body of heater and be located at the collet in body of heater, the bottom of body of heater has hot wind inlet, also microwave catheter is provided with in described body of heater, described microwave catheter is connected with microwave generator, and described microwave generator is positioned at the outside of body of heater.
The microwave outlet of microwave catheter is arranged in the bottom of body of heater.
Body of heater is jacket type structure, and it comprises the inner bag of internal layer and outer field shell, and inner bag is provided with inside and outside penetrating pore, and shell is provided with the exhaust outlet for being connected with corresponding dust-precipitator.
Drying materials system is by the following technical solutions: drying materials system, comprise tower drier and the feeding device corresponding with tower drier and feeding device, tower drier comprises body of heater and is located at the collet in body of heater, feeding device is positioned at below body of heater, the bottom of body of heater has hot wind inlet, also be provided with microwave catheter in described body of heater, described microwave catheter is connected with microwave generator, and described microwave generator is positioned at the outside of body of heater.
The microwave outlet of microwave catheter is arranged in the bottom of body of heater.
Body of heater is jacket type structure, and it comprises the inner bag of internal layer and outer field shell, and inner bag is provided with inside and outside penetrating pore, and shell is provided with the exhaust outlet for being connected with corresponding dust-precipitator.
Because the body of heater of this pair of heat source vertical type has hot wind inlet, and in its body of heater, be also provided with microwave catheter, microwave catheter is connected with microwave generator, therefore, when in use, first the material entered in body of heater will carry out heat exchange with hot blast and by drying from outer to inner, material after hot blast preliminarily dried will be heated by inside and outside the microwave that is directed into by microwave catheter in body of heater simultaneously, thus greatly can shorten hot-wind-drying time, accelerate the flow velocity of material in body of heater, finally reach the object of the drying efficiency improving tower drier.
Further, after the bottom in body of heater is located in the outlet of the microwave of microwave catheter, can realize drying the layering of material, specifically, first can by hot-air seasoning to a certain degree on the top of body of heater when material enters body of heater, when it moves to lower portion of furnace body, through the preliminary oven dry of hot blast, at this moment just can give full play to the efficiency of heating using microwave, fast by drying materials to meeting the requirements; The body of heater of jacket type is conveniently to the process of the waste gas of discharging from body of heater.
