Description
Technical field
The utility model relates to a kind of grain drying tower.
Background technology
Existing grain drying tower hot fuel used is that the raw coal of 5500 kilocalorie-6000 kilocalories does fuel, and combustion grate does not have boiler part, and hot flue gas body directly enters heat exchanger heat exchange by air-introduced machine air inducing.Combustion heat-exchange process is simple, and heat exchange loss is large, and the hot blast temperature of drying tower is between 140 degree-170 degree.Because air temperature is too high, the too much coffee color of grain as easy as rolling off a log appearance in drying course is stuck with paste grain, makes the grain of drying reduce quality.
Utility model content
Goal of the invention of the present utility model is to provide a kind of grain drying tower, good drying effect, and can effectively reduce oven dry cost.
Realize the technical scheme of the present utility model object:
A kind of grain drying tower, comprises tower body, and tower body top is provided with grain inlet, and bottom is provided with grain outlet, it is characterized in that: in tower body, be provided with successively from the inside to the outside hot cold air chamber, grain layer, protective layer; Hot cold air chamber is made up of hot air chamber and cold air chamber, and hot air chamber is positioned at the top of cold air chamber, between hot air chamber and cold air chamber, is provided with dividing plate; Grain layer is made up of outer steel mesh and inner steel web, and the top of grain layer is communicated with grain inlet, and the bottom of grain layer is communicated with grain outlet; Also comprise boiler, the pipeline of boiler connects heat exchanger, and the hot air duct of heat exchanger is communicated with hot air chamber; Also comprise air-cooler, the cold air duct of air-cooler meets cold air chamber.
In grain layer, be provided with mixed grain agitator arm.
The top of hot air chamber is provided with air-resistance cover moving up and down, and air-resistance cover is connected with tower body top by chain.
Also be provided with moisture outlet, moisture outlet communicates with protective layer.
Boiler adopts straw burning boiler.
The beneficial effect the utlity model has:
The utility model, in tower body, is provided with hot cold air chamber, grain layer, protective layer from the inside to the outside successively; Hot cold air chamber is made up of hot air chamber and cold air chamber, and hot air chamber is positioned at the top of cold air chamber, and grain layer is made up of outer steel mesh and inner steel web, also comprises boiler, and the pipeline of boiler connects heat exchanger, and the hot air duct of heat exchanger is communicated with hot air chamber; Due to the distinctive drying tower structural design of the utility model, can realize with the lower temperature of 60 degree-80 degree and dry grain, effectively improve grain heat-drying quality, reduce and dry cost.The utility model can adopt straw burning boiler, does fuel with stalk, can further reduce oven dry cost, energy-conserving and environment-protective.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, tower body top is provided with grain inlet 2, and bottom is provided with grain outlet 12, in tower body, is provided with successively from the inside to the outside hot cold air chamber, grain layer, protective layer 5; Hot cold air chamber is made up of hot air chamber 21 and cold air chamber 22, and hot air chamber 21 is positioned at the top of cold air chamber 22, between hot air chamber 21 and cold air chamber 22, is provided with dividing plate 20; Grain layer is made up of outer steel mesh 7 and inner steel web 4, and the top of grain layer is communicated with grain inlet 2, and the bottom of grain layer is communicated with grain outlet 12, is provided with mixed grain agitator arm 19 in grain layer.Also comprise straw burning boiler 16, the pipeline 6 take-over type heat exchangers 9 of boiler 16, the hot air duct 14 of pipe heat exchanger is communicated with hot air chamber 21; Also comprise air-cooler 11, the cold air duct 15 of air-cooler meets cold air chamber 22.The top of hot air chamber 21 is provided with air-resistance cover 3 moving up and down, and air-resistance cover is connected with tower body top by chain.Also be provided with moisture outlet 18, moisture outlet communicates with protective layer, and tower body top is provided with rain cover 1.
When work, the heat energy that straw burning boiler 16 produces, is pressurizeed in boiler from pressurized circulation pump 8, and the thermal medium in pipeline 6 enters pipe heat exchanger 9.Air-heater 10 is dried, and produces hot blast by hot-flow flue 14 through heat exchanger 9, sends into hot air chamber 21.Malleation thermal current in hot air chamber 21, by inner steel web 4, to the grain heating, drying of grain layer, enters protective layer 5 with the moisture of moisture from outer steel mesh 7, and moisture, owing to there being pressure, is discharged from moisture outlet 18.Need the grain grain inlet 2 of drying, be slipped to voluntarily grain layer, when grain drops to cold air chamber 22, blown a cold wind over through cold air duct 15 by air-cooler 11, enter cold air chamber 22, blow to grain layer by inner steel web 4, cold wind is taken temperature contained grain layer out of, gives the grain of having dried cooling.In drying course, the hot blast that grain layer the contacts inequality of being inside and outside heated, in the time that grain layer slowly falls, mixed grain agitator arm 19 rotates and stirs, and makes all full and uniform hot blasts that touches of grain layer inside and outside.Air-resistance cover 3 is located at hot air chamber 21 topmost, and in the time that drying course will finish, grain inlet 2 is closed to enter grain, continues to dry, and air-resistance cover 3 is declined with grain layer by chain control and falls simultaneously.Restart while oven dry, then by chain, air-resistance cover 3 is risen.The grain of having dried is discharged from grain outlet 12.The size that the slip velocity of grain is opened by the control valve 13 of putting out cereal in drying course is controlled.
