Description
Technical field
The utility model relates to a kind of grain drier, is specifically related to a kind of energy-saving grain drier.
Background technology
Along with the continuous popularization of high-yield crop kind, water content during grain harvest has the trend of rising, and this just brings certain difficulty to drying operation.At present, some producers, in order to strengthen the precipitation range of drying machine, have employed higher hot blast temperature, increase air quantity and the blast of drying medium.Due to the dryer section of existing grain drier and delay section generally less, if adopt higher hot blast temperature and airflow pressure, grain own temperature will be made to raise gradually, along with the reduction of grain moisture content, the waste vapour got rid of in tower becomes undersaturated water vapour by saturated water vapour gradually, unsaturated like this waste vapour will take away a large amount of heats, increases oven dry cost.In addition along with the reduction of grain moisture content, the rising gradually of grain own temperature, too increases the probability that quick-fried waist, frightened line, decortication appear in grain, reduces the interests that grain quality compromises grain processing enterprise.Meanwhile, some grain driers due to drying medium hot blast distribute in tower inequality cause grain drying after moisture content uneven, also can with half-cooked grain grain, thus cause the problem that grain quality declines and not easily stores.
Utility model content
The purpose of this utility model be in order to solve thermal loss when existing grain drier uses excessive, dry high cost and the uneven problem of grain moisture content after drying, and then a kind of energy-conservation grain drier provided.
The technical solution of the utility model is: a kind of energy-saving grain drier, comprise crop inlet pipe, pre-reservoir, dryer section assembly, cooling layer, angular tube, hot blast air inlet pipe, cold wind air inlet pipe, air-heater, king-tower base, air-cooler, multiple hothouse and multiple exhaust chamber, king-tower base is disposed with the cooling layer be communicated with each other, dryer section assembly, pre-reservoir and crop inlet pipe, hot blast air inlet pipe is located at the both sides of multiple dryer section assembly and lower end is communicated with air-heater, the upper and lower two ends of cold wind air inlet pipe are communicated with air-cooler with cooling layer respectively, hothouse is all communicated with hot blast air inlet pipe, dryer section assembly comprises eight to ten dryer section, be arranged in parallel between dryer section and be interconnected, the sidewall of dryer section assembly is provided with multiple hothouse, in dryer section, level is provided with multiple angular tube, angular tube has multiple air-vent, the sidewall of dryer section assembly also has multiple exhaust chamber.
The utility model compared with prior art has following effect:
Energy-saving grain drier of the present utility model, is provided with the three phases of Grain Drying Process, and dry run is divided warm-up phase, constant rate drying period and falling rate drying period by the quantity of reasonable distribution hothouse and arrangement mode.Further reasonable disposition air inflow and the ratio of capacity in Grain Drying Process again, reaches energy-conservation effect.For eight dryer section, concrete mode is as follows:
1, warm-up phase A adopts continuous mixed-flow drying technology, have employed 5 hothouse air inlets, the mode that 2 exhaust chambers are given vent to anger, to reach being rapidly heated of grain.Be proven, will increase the difficulty of manufacturing cost and manufacturing process as increased air inlet or capacity again, the words of minimizing are difficult to again realize good drying effect.2, constant rate drying period B adopts concurrent-countercurrent drying process, is specially 6 hothouse air inlets, the mode that 4 exhaust chambers are given vent to anger, to reach at the uniform velocity fast rainfall object.3, falling rate drying period C adopts direct-flow tempering drying process, is specially 4 hothouse air inlets, 2 exhaust chambers give vent to anger mode, to reach the slow tempering object of slow precipitation.According to above-mentioned mentality of designing, often increase a drying layer, two hothouses can be increased thereupon.
2, the utility model several air-vents arranged in parallel on angular tube, effectively increase the heating surface area of grain, decrease the resistance that drying medium hot-air penetrates grain layer, depth of grain layer can be strengthened simultaneously, effectively reduce the mass rate of emission of waste vapour and scattering and disappearing of temperature, reach energy-conservation object.
3, energy-saving grain drier of the present utility model is provided with eight to ten dryer section, and the hothouse that each dryer section configures is separately positioned on the both sides of each dryer section, the hot blast making to enter dryer section can be complementary along axis back and forth or left and right, such drying medium hot blast is by after producing jet after hothouse, the hot blast skewness phenomenon caused is compensated in the opposite direction by the hothouse of opposite side, the hothouse air inlet of two adjacent dryer section configurations is vertically arranged in the horizontal direction, effectively change the flow direction of grain, after making grain heat-drying, moisture content is more even.When hothouse quantity is more than ten, not only increase technology difficulty and cost, to drying effect also without significantly promoting.
