Description
Technical field
The utility model relates to a kind of drying plant of grain, and particularly a kind of isobaric grain-drying tower belongs to the grain machinery technical field.
Background technology
In the grain processing and the field of circulation, the precipitation drying of cereal is finished by vertically arranged grain-drying tower usually.Existing grain-drying tower comprises frame and is supported on the oven dry storehouse on the frame and cools off the storehouse, the oven dry storehouse comprises the baking zone that multilayer is stacked successively, each baking zone is respectively equipped with staggered venting box, oven dry top, storehouse is provided with charging aperture and hot-blast outlet, oven dry bottom, storehouse is provided with discharging opening and hot blast import, and the hot blast that thermal source produces is delivered to the hot blast import by air-heater through warm-air pipe; The cooling storehouse is arranged on below, oven dry storehouse, the cooling storehouse comprises the cooling layer that multilayer is stacked successively, each cooling layer is respectively equipped with staggered venting box, cooling top, storehouse is provided with charging aperture and cold wind outlet, oven dry bottom, storehouse is provided with discharging opening and cold wind import, and atmosphere is delivered to the cold wind import by air-cooler through cool air hose.
Grain earlier enters the oven dry storehouse from the charging aperture of topmost, relies on self gravity each baking zone of slowly flowing through downwards; Hot blast enters from the hot blast import of oven dry bottom, storehouse, flows from bottom to top, and grain and hot blast carry out the wet exchange of heat in flow process, and hot blast enters atmosphere by hot-blast outlet after taking away grain moisture content, realizes grain heat-drying; Then grain enters the cooling storehouse and continues to flow downward, same cold wind and grain carry out the wet exchange of heat, and cold wind is taken away the moisture and the heat of grain, and grain is cooled off, reach grain after certain moisture and the temperature outside discharging opening is discharged drying tower, finish the precipitation dry run of grain.
There is following shortcoming in this grain-drying tower: 1. hot and cold wind medium is sent into cooling layer and baking zone by pipeline respectively, the general air quantity of drying tower is bigger, wind speed in the pipeline is bigger, and windage roughly with square being directly proportional of wind speed, therefore hot and cold wind medium flows in the air channel and has bigger resistance, adds that interior hot and cold wind medium of drying tower and grain reverse flow have strengthened windage especially.This resistance is to overcome by the blast that hot and cold blower fan produces, and power of fan and blast are directly proportional, and blower fan will produce bigger blast, just must increase power of fan, causes the oven dry energy consumption to increase.
2. because the air intake surface of baking zone and cooling layer has certain cross dimensions, adopt air duct blow, can cause air quantity skewness on the air intake section, promptly carry out the air quantity inequality of the wet exchange of heat with grain, cause the moisture inequality behind the grain heat-drying, influence quality after the baking of grain.
3. grain is mingled with a large amount of plasters, grain can produce a large amount of scurfs in flow process simultaneously, the hot and cold wind medium of existing drying tower and grain carry out the wet exchange of heat back and directly enter atmosphere by exhaust outlet, the dust that produces in the drying course enters atmosphere together under oven dry waste gas drives, cause the drying tower work under bad environment.
