Abstract
The utility model discloses a directly-heated type aeration drying grain bin and relates to the technical field of grain bin drying. The aeration drying grain bin comprises a grain bin body, an over-ground cage, a pressure fan, an exhaust fan, a heating cable, a temperature controller, a temperature/humidity sensor and a power source. The pressure fan is installed at the bottom of the over-ground cage; the exhaust fan is installed at the top of the grain bin body; the heating cable is located in a grain pile on the over-ground cage and is connected with the temperature controller; the temperature/humidity sensor is located in the grain pile; the power source is respectively connected with the pressure fan, the exhaust fan, the heating cable and the temperature/humidity sensor. The over-ground cage for ventilation is combined with the heating cable arranged in the grain pile, so that the cost of a drying device is greatly reduced. The aeration drying grain bin has the advantages that grains and air in the grain pile are heated in advance and wet and hot air in the grain pile is replaced by natural dry air. The method that pressure air on the lower portion of the over-ground cage is combined with grain bin air draft on the upper portion of the grain pile is adopted and the ventilation effect is improved.
Description
Technical field
The utility model relates to depot technical field of drying, specifically a kind of directly-heated type aeration drying grain storage storehouse.
Background technology
The drying means of grain is a lot, and the state according to grain when dry, can be divided into grain drying unification: dynamically dry and static dry.Most widely used during grain static state is dry is drying generator, the more drying generator technology of application is that high moisture grain is left in the storehouse of being furnished with solid mechanical ventilating system at present, utilize natural air or add hot-air as drying medium, carry out mechanical ventilation drying to thering is the high moisture grain that certain heap is high, by grain moisture content drop to can safe storage till.Wherein most typical is the modes such as natural-draft drying, heating aeration-drying and air blow and agitation are dried.Its operating process is utilized mechanical ventilation system exactly, the pressure (being generally positive pressure method) that suitable drying medium (air or a little hot-air) is produced by blower fan, continuously send among grain heap, allow the drying medium of high temperature low humidity fully contact with high-moisture grain grain, grain grain surface moisture is constantly vaporized, and progressively shift out the process of grain heap.From this dry run, drying medium utilization be nature dry air or a little heat dry air; Dry object is the crops such as high moisture grain and oil plant, before and after dry, is to deposit in all the time among warehouse.But current drying generator equipment price is more expensive, operate also more loaded down with trivial detailsly, therefore limit it and applied.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of cheap aeration drying grain storage storehouse simple in structure.
The utility model is achieved through the following technical solutions: a kind of aeration drying grain storage storehouse, comprises depot, ground cage, pressure fan, ventilating fan, heating cables, temperature controller, warm and humid sensor and power supply; Described pressure fan is arranged on cage bottom on the ground; Described ventilating fan is arranged on depot top; Described heating cables is arranged in the grain heap on the cage of ground and is connected with temperature controller; Described warm and humid sensor is arranged in grain heap; Described power supply is connected with pressure fan, ventilating fan, heating cables and warm and humid sensor respectively.
It is further: described heating cables is the special heating cables of low-temp radiating.
Using method: conveying grain into storehouse finishes the rear heating cables (the large cable density of original moisture is large, otherwise few) that inserts in grain heap according to the size of the original moisture of grain.Heating cables is connected with temperature controller, according to different grain varieties, restriction heating-up temperature is set.After reaching design temperature, open pressure fan from the ventilation of ground cage, on grain face, ventilating fan is opened simultaneously.The percent opening of cage will reach 30%～35% on the ground.
Heating cables is the special heating cables of low-temp radiating.High moisture grain grain bulk height generally below 4.5 meters drying effect better.
The utility model adopts cage on the ground to ventilate in conjunction with adding heating cables in grain heap, thereby greatly reduces drying equipment price.Core of the present utility model is first to heat Liang Dui China Oil and Food Import and Export Corporation grain and air, then uses damp-heat air in nature dry air displacement grain heap.And draft type adopts cage bottom pressure wind on the ground in conjunction with grain heap top depot window exhausting, to improve ventilation effect.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, depot; 2, ground cage; 3, pressure fan; 4, ventilating fan; 5, heating cables; 6, temperature controller; 7, warm and humid sensor; 8, power supply.
Embodiment
Be below a specific embodiment of the present utility model, now by reference to the accompanying drawings the utility model be described further.
As shown in Figure 1, a kind of aeration drying grain storage storehouse, cage 2 is on the ground installed in depot 1, ventilating fan 4 is installed at the top of depot 1, pressure fan 3 is installed in the bottom of cage 2 on the ground, heating cables 5 is connected with temperature controller 6 and inserts in the grain heap on the cage 2 of ground, and temperature controller 6 is controlled the heating-up temperature of heating cables 5; Warm and humid sensor 7 is arranged in grain heap, for the temperature and humidity of Real-Time Monitoring grain heap; Power supply 8 provides power supply for whole device.
Using method: conveying grain into storehouse finishes to insert the original moisture of heating cables 5(according to the size of the original moisture of grain in grain heap electric heating cable 5 density are large greatly afterwards, otherwise few).Heating cables 5 is connected with temperature controller 6, according to different grain varieties, restriction heating-up temperature is set.Reach and open pressure fan 3 after design temperature and ventilate (forced) from ground cage 2, on depot 1, ventilating fan 4 is opened simultaneously.The percent opening of cage 2 will reach 30%～35% on the ground.
Heating cables 5 is the special heating cables of low-temp radiating.High moisture grain grain bulk height generally below 4.5 meters drying effect better.
