Energy-efficient grain drying unit of the present utility model, reasonable in design, floor space is little, economic and practical, has quick heating, temperature range is wide in range, homogeneous heating, the advantage of the high and energy-saving and emission-reduction of the thermal efficiency, waste heat is recyclable, make hot gas cycle utilization, grain can the powerful oven dry of choice for use hot blast or normal temperature Quick-air-drying.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the utility model energy-efficient grain drying unit;
Accompanying drawing 2 is the cutaway view of the boiler of the utility model energy-efficient grain drying unit.
Detailed description of the invention
, be described further the utility model energy-efficient grain drying unit below in conjunction with accompanying drawing 1 and accompanying drawing 2:
Embodiment 1
Energy-efficient grain drying unit of the present utility model, is made up of boiler 3 and drying baker 7, as shown in Figure 1.Air blast 1 is connected with the boiler tube 15 in boiler 3 by cool air hose 2, boiler tube 15 is connected with air-introduced machine 5 entrances by warm-air pipe 4, the outlet of air-introduced machine 5 is connected with hot blast shower nozzle 6, the below of hot blast shower nozzle 6 in drying baker 7, in drying baker 7, longitudinally connect the many screen casings 8 of arranging.Described screen casing 8 is fixing with the sieve plate 9 of sieve aperture by drying baker 7 upper ends, and four sides cone 10 surfaces of drying baker 7 are exposed in lower end, and there are sieve aperture and upper end closure, lower ending opening in screen casing 8 surfaces.
Embodiment 2
Energy-efficient grain drying unit of the present utility model, is made up of boiler 3 and drying baker 7, is provided with boiler tube 15 in boiler 3, and boiler tube 15 is connected and is formed by several vertical boiler tubes 14 and horizontal boiler tube 13, as shown in Figure 2.
Cool air hose 2 one end are communicated with air blast 1, and the other end is communicated with respectively with the horizontal boiler tube 13 of boiler tube 15 both sides after being divided into two-way; One end of warm-air pipe 4 is communicated with boiler tube 15 horizontal boiler tube 13 topmost, the other end is communicated with air-introduced machine 5 entrances, the outlet of air-introduced machine 5 is connected with hot blast shower nozzle 6, the below of hot blast shower nozzle 6 in drying baker 7, in drying baker 7, longitudinally connect the many screen casings 8 of arranging.Described screen casing 8 is fixing with the sieve plate 9 of sieve aperture by drying baker 7 upper ends, and four sides cone 10 surfaces of drying baker 7 are exposed in lower end, and there are sieve aperture and upper end closure, lower ending opening in screen casing 8 surfaces.
Have grain entrance 12 on drying baker 7 tops, 7 li of drying bakers are four sides cone 10 shapes, and grain-export 11 is arranged at four sides cone 10 bottoms of drying baker 7.Sandwich filling in described four sides cone 10 can make the packing material of screen casing 8 thermally equivalents.
Energy-efficient grain drying unit of the present utility model is in the time of work, in the horizontal boiler tube 13 of boiler, blast cold air by cool air hose 2 by air blast 1, air in the heat meeting furnace tubing 15 that boiler 3 produces at combustion fuel, because laterally boiler tube 13 and vertical boiler tube 14 are communicated with, air is because temperature rising volume becomes greatly, density diminishes, and hot-air can rise in the horizontal boiler tube 13 of top gradually by vertical boiler tube 14.Air-introduced machine 5 extracts hot-air from warm-air pipe 4, after compression, spray from hot blast shower nozzle 6 high speeds.Due to the lower ending opening of screen casing 8, upper end closure, high velocity, hot air pours in screen casing and can only spray from the sieve aperture on screen casing 8 surfaces, thereby promotes the temperature of whole drying baker 7, and then dries grain in drying baker 7.For homogeneous heating drying baker 7, in the cone 10 of the four sides, lower end of drying baker 7, fill the material that makes screen casing 8 homogeneous heatings, such as asbestos.If do not use boiler 3 to heat, drying course is normal temperature Quick-air-drying.
