Existing tower drier is incorporated into hot blast dryer or waste gas is discharged to dryer by air inducing flue or induced duct, as adopted this technical scheme in Chinese patent application 201010546610.3 and 200710061499.7, due to the restriction of air inducing flue or induced duct bore structure, in dryer, hot blast can not see through the material bed thermal material that adds equably, high at air inducing flue or induced duct place hot air flow, cause drying materials inhomogeneous, even catch fire because hot-spot causes material.
Summary of the invention
The purpose of this utility model is to overcome the defect that above-mentioned dryer exists, and a kind of tower drier of even distributing wind is provided.
The technical solution of the utility model is: a kind of tower drier, comprise feeding warehouse, material distributing cone, drying cylinder body, discharge bucket, it is characterized in that: described drying cylinder body comprises inner barrel, outer cylinder body and air duct, between described inner barrel and outer cylinder body, be provided with collet, at the position, gap of collet formation material drying channel, on inner barrel and outer cylinder body, have annular tuyere; Described air duct is the circular cylinder around outer cylinder body outside, air duct is divided into the exhaust tube on top and the air intake cylinder of bottom, the exhaust tube on top is provided with exhaust outlet, the air intake cylinder of bottom is provided with air inlet, between exhaust tube and air intake cylinder, be provided with partition panel, isolated hot gas is directly circulation between exhaust tube and air intake cylinder.
In preferred version, described exhaust outlet is arranged on the sidewall of exhaust tube, and described air inlet is arranged on the sidewall of air intake cylinder.
Further, in preferred version, on described air intake cylinder, be axially provided with two-layer air inlet along air duct, upper strata is high temperature air inlet, and lower floor is low temperature air inlet.
Further in preferred version, between the high temperature air inlet of air intake cylinder and low temperature air inlet, be provided with partition panel, directly circulation up and down of hot gas in isolated air intake cylinder.
Further, in preferred version, described inner barrel, outer cylinder body and air duct are concentric drums.
Technical solutions of the utility model have adopted the annular air duct around outer cylinder body, hot blast enters after the air intake cylinder of annular air duct, along the annular tuyere circulation of outer cylinder body, see through the material bed thermal material that adds, enter inner barrel through the annular tuyere of inner barrel, in inner barrel on flow, and then flow through material bed by the annular tuyere of inner barrel, heat the material on top, then enter the exhaust tube of annular air duct by the annular tuyere of outer cylinder body, discharge from exhaust outlet.Owing to having adopted annular air duct and annular tuyere, hot blast is evenly circulation along the circumferential direction, thereby heating material is even, has avoided drying materials shortcoming inhomogeneous, that even catch fire because of hot-spot.In addition, in the technical program, when entering inner barrel from air intake cylinder, hot blast sees through the material bed heating for the first time having realized material, when entering chimney fan from inner barrel, hot blast again sees through the material bed heating for the second time having realized material, thereby the heat exchange of the technical program is abundant, improve the utilization ratio of heat energy.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the cutaway view of Fig. 1 in A-A direction.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1 and Figure 2, tower drier of the present utility model comprises feeding warehouse 1, material distributing cone 2, drying cylinder body 4, discharge bucket 9, material promotes in the feeding warehouse 1(accompanying drawing that enters sealing and does not show elevator through elevator), material distributing cone 2 in feeding warehouse 1 becomes cylindrical shape material bed material dispersion, the material bed drying cylinder body 4 that enters under Action of Gravity Field, material discharging from discharge bucket 9 after drying.
Drying cylinder body 4 comprises inner barrel 17, outer cylinder body 15 and air duct 13, between inner barrel 17 and outer cylinder body 15, is formed with collet 16, at the position, gap of collet 16 formation material drying channel 3, has annular tuyere 14 on inner barrel and outer cylinder body.Air duct 13 is the circular cylinder around outer cylinder body outside, and air duct 13 is divided into the exhaust tube 6 on top and the air intake cylinder 8 of bottom, and the exhaust tube 6 on top is provided with exhaust outlet 5, and the air intake cylinder 8 of bottom is provided with air inlet 10.Between exhaust tube 6 and air intake cylinder 8, be provided with annular partition panel 7, partition panel 7 is tightly connected with the inwall of air duct 13 and the outer wall of outer cylinder body 15 respectively, and isolated hot blast is directly circulation up and down between exhaust tube 6 and air intake cylinder 8.
