A kind of pair of thermal source tower drier and use the drying system of this dryer
Technical field
The present invention relates to the material drying machine field, particularly relate to a kind of pair of thermal source tower drier and use the drying system of this dryer.
Background technology
Tower drier claims again vertical drier, and it is widely used to the production processes such as moulded coal, cement, chemical fertilizer to the oven dry of material, has little, small investment and the stable characteristics of taking up an area.
Present tower drier comprises body of heater, and the body of heater top has charging aperture, and the bottom has discharge gate and hot blast import, and its madial wall is provided with lifting blade, in addition, also is provided with collet in the body of heater, and the exhaust outlet of hot blast import passes in the collet.In body of heater, send into hot blast by the hot blast import during work, by corresponding conveying device material to be dried is added body of heater from the charging aperture at body of heater top, the material that enters body of heater slowly moves down by gravity on one side, carry out heat exchange with the hot blast that enters body of heater on one side, finally reach the purpose of oven dry, carried out the hot blast of heat exchange with material and discharge outside the body of heater from the exhaust outlet on the body of heater.
More than from its operation principle as can be known, thermal source is one of main factor that affects the tower drier drying efficiency, yet, in actual production process, be that certain requirement is arranged to the air quantity that passes into the hot blast in the tower drier, and present tower drier all is to come material is dried by hot blast, in this case, for the dry requirement of the material of can trying one's best, can only be to reduce the flowing velocity of material in body of heater, this has obviously limited the drying efficiency of tower drier.
Summary of the invention
The object of the present invention is to provide a kind of pair of thermal source tower drier, to improve the drying efficiency of existing tower drier.
Simultaneously, the present invention also aims to provide the drying materials system that uses above-mentioned dryer.
In order to address the above problem, two thermal source tower driers are by the following technical solutions: two thermal source tower driers, comprise body of heater and the collet of being located in the body of heater, the bottom of body of heater has the hot blast import, also be provided with microwave catheter in the 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 inner bag and the outer field shell of internal layer, and inner bag is provided with inside and outside penetrating pore, and shell is provided with the exhaust outlet that is connected for corresponding dust-precipitator.
The drying materials system is by the following technical solutions: the drying materials system, comprise tower drier and feeding device and the feeding device corresponding with tower drier, tower drier comprises body of heater and the collet of being located in the body of heater, feeding device is positioned at the body of heater below, the bottom of body of heater has the hot blast import, also be provided with microwave catheter in the 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 inner bag and the outer field shell of internal layer, and inner bag is provided with inside and outside penetrating pore, and shell is provided with the exhaust outlet that is connected for corresponding dust-precipitator.
Because the body of heater of this pair thermal source tower drier has the hot blast import, and in its body of heater, also be provided with microwave catheter, microwave catheter is connected with microwave generator, therefore, when in use, enter material in the body of heater and will be at first carry out heat exchange with hot blast and by from outer to inner drying, material behind the hot blast preliminarily dried will be directed into by microwave catheter simultaneously heating inside and outside the microwave in the body of heater, thereby the heated-air drying time can be shortened greatly, accelerate the flow velocity of material in body of heater, finally reach the purpose of the drying efficiency that improves tower drier.
Further, after the outlet of the microwave of microwave catheter is located at bottom in the body of heater, can realize the layering oven dry to material, specifically, at first the preliminary oven dry of hot blast can by hot-air seasoning to a certain degree, when it moves to lower portion of furnace body, have been passed through in the top at body of heater when material enters body of heater, at this moment just can give full play to the efficient of heating using microwave, fast with drying materials to meeting the requirements; The body of heater of jacket type is in order to make things convenient for the processing to the waste gas of discharging from body of heater.

The specific embodiment
The embodiment of two thermal source tower driers as shown in Figure 1, comprises body of heater, the top of body of heater is provided with charging aperture, its underpart is provided with hot blast import 101, and the bottom is provided with discharge gate, in the present embodiment, body of heater is jacket type structure, it comprises inner bag 11 and the outer field shell 12 of internal layer, and inner bag 11 is provided with inside and outside penetrating pore, and its medial surface is provided with lifting blade 13, shell is provided with exhaust outlet 102, and exhaust outlet 102 is used for being connected with corresponding deduster.
Also be provided with collet 14 and microwave catheter 15 in the inner bag 11 of body of heater, collet 14 roughly is the tapered sleeve shape of butt, the microwave outlet of microwave catheter 15 is housed in the collet 14 and is positioned at lower portion of furnace body, and it is connected with microwave generator 16, and microwave generator 16 is positioned at the outside of body of heater.
In other embodiment of two thermal source tower driers, the outlet of the microwave of the microwave catheter in above-described embodiment can also be located at middle part or the top of body of heater, perhaps in upper, the middle hypomere of body of heater microwave catheter and corresponding microwave generator is set respectively.
The embodiment of drying materials system, as shown in Figure 2, this drying system comprises tower drier 201 and feeding device 202 and the feeding device 203 corresponding with tower drier 201, wherein the structure of tower drier 201 is identical with the structure of the embodiment of above-mentioned tower drier, it will not go into details herein, feeding device 202 is used for adding material to be dried to the charging aperture of tower drier 201, feeding device 203 is positioned at the place, below of tower drier, and it is used for receiving and failing away from material tower drier 201 discharges, the process oven dry.
