Technical field
The present invention relates to a kind of drying plant, especially a kind of dryer of drying graininess flammable materials.
Background technology
The large-scale drying plant of drying at present granular material in industrial production common are rotary drying machine and tower drier, and wherein tower drier has advantages of that occupied ground area is little, drying efficiency is high, small investment, in market, obtains a wide range of applications.
Tower drier is by hot-blast stove, material elevator, dryer main body and exhaust apparatus form, its operation principle is that the material of required oven dry is risen to the appearance hopper at dryer top by elevator, self gravitation by material, by material dispersion, forms a barrel bed of material by material distributing cone, hot blast is forced heat lateral traction to see through material bed by air-introduced machine, carry out heat exchange, after the steam producing and waste gas are gathered dust by exhaust apparatus, discharge, to reach the object of oven dry.
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, restriction due to 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 because hot-spot causes material, catch fire.
Summary of the invention
The object of the invention is to overcome the defect that above-mentioned dryer exists, a kind of tower drier of even distributing wind is provided.
Technical scheme of the present invention 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, along air duct, be axially provided with two-layer air inlet, 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 solution of the present invention has adopted the annular air duct around outer cylinder body, hot blast enters after the air intake cylinder of annular air duct, annular tuyere circulation along outer cylinder body, see through the material bed thermal material that adds, through the annular tuyere of inner barrel, enter 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 by the annular tuyere of outer cylinder body, enter the exhaust tube of annular air duct, from exhaust outlet, discharge.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, improved the utilization ratio of heat energy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is that Fig. 1 is at the cutaway view of A-A direction.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1 and Figure 2, tower drier of the present invention 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.
