Description
Affiliated technical field
The utility model relates to a kind of mixed-flow grain drier that grain heat-drying is handled that is used for.Owing to increased the tempering commutation function in dry run, this machine can under the situation of big (〉=5%), fully guarantee the quality of grain at the disposable precipitation range of grain.On the other hand, the tempering commutation can suitably improve hot blast temperature, has strengthened the operating efficiency of drying machine.
Background technology
At present, the mixed-flow grain drier has become the mainstream model that is most widely used in the international and domestic grain heat-drying industry.As everyone knows, in existing mixed-flow grain drier, evenly arranging the ventilating duct of many complete five jiaos of types and half five jiaos of types from top to bottom continuously, kept in drying course lasting drying, so the mixed-flow grain drier has the advantage that big, the disposable precipitation range of dry tenacity reaches good combination property greatly to grain.In actual production, the user is for the consideration of economic benefit aspect, and a precipitation range all surpasses 8% when grain heat-drying, when the highest even above 15%.It is bigger that this rapid draing causes grain to shrink on the one hand, has influence on color and luster, the profile of grain, and make the moisture unevenness of finished product of grain become big, causes between the storage life grain rotten easily; On the other hand, lean on the grain of hot-air channel side, cause these particles to produce face cracks even the burnt paste of generation when hot blast temperature is higher owing in dry run, contact with the steel plate of high temperature always.Above-mentioned situation causes the quality behind the grain heat-drying to descend, and then has influence on the economic benefit of processing enterprise.
Summary of the invention
For the drawback that grain quality descends after the oven dry bigger and that produce near phenomenons such as the grain of hot-air channel side continue to be heated at disposable precipitation range that overcomes that existing mixed-flow grain drier exists, the utility model provides a kind of novel drying machine, this machine can not only guarantee to dry the quality of back grain, and can also improve the operating efficiency of existing drying machine.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
In traditional mixed-flow drying machine stage casing, increase by a special tempering commutation section, make previous continuous dryer section be divided into primary drying section, tempering commutation section and redrying section three parts, three parts rely on ring flange to connect.
Duan Weisan section of tempering commutation is respectively once commutation section, secondary commutation section and three commutation sections.In once commutation section, with steel plate the drying machine cross section is divided into equirotal four rectangular areas from the exhaust passage side to the inlet channel side, again each rectangular area is divided into four bias current funnels; In secondary commutation section, only two rectangular areas, centre are divided into the bias current funnel; Three times the commutation section is divided into equirotal four rectangular areas with steel plate equally, and each rectangular area is divided into four bias current funnels.Three commutation sections both can arrange continuously, also can be arranged apart, and promptly by the section+dryer section layout that time commutates of commutation section+dryer section+secondary commutation section+dryer section+three once.
Tempering commutation section has two kinds of functions of tempering and commutation concurrently, that is: can make on the one hand through the dried grain of prime and in the tempering process, reach water balance inside and outside the grain, can in relying on that gravity is top-down and flow, grain make grain that is positioned at the hot blast inlet side and the grain that is positioned at exhaust side realize location swap on the other hand, avoid the lasting conduction heating of hot blast inlet side grain, thereby effectively guaranteed the quality of grain.
The beneficial effects of the utility model are, can make through one section dried grain in tempering, also can realize being positioned at the grain of hot blast inlet side and the grain location swap of exhaust side, fully guarantee the oven dry quality of grain.

The specific embodiment
By Fig. 1 and Fig. 2 as can be seen, this utility model drying machine by grain storage section (1), dryer section one (2), tempering commutation section (3), a dryer section two (4), cooling section (5), unloading section (6), exhaust passage (7) and inlet channel (8) totally eight parts formed, connect by bolt between this eight part.Common mixed-flow drying machine has then lacked tempering commutation section, and is regardless of dryer section one and dryer section two, all is dryer section between cooling section and grain storage section.
Commutation process when Fig. 3 tempering commutation section reversing principle figure has represented that grain is flowed through tempering commutation section from top to bottom.Utilize steel plate that the drying machine cross section from left to right is divided into 4 rectangular areas of the same size, represent with α, β, γ, θ district respectively, the commutation process of grain is realized by three different commutation processes in the drying machine, is respectively commutating zone A-A, a secondary commutating zone B-B and three commutating zone C-C.After once commutating, the grain that is positioned at α, β, γ and θ district varies to β, α, θ and γ district from left to right; Secondary commutation only changes the grain position that is positioned at α and θ district, after the commutation from left to right the position of grain become β, θ, α and γ; The position of three final grains in commutation back becomes θ, β, γ and α, has realized the exchange of grain positions, both sides.
Fig. 4, Fig. 5 and Fig. 6 are respectively once the cross-sectional views of the section of commutation, secondary commutation section and three commutation sections.
Fig. 4 has represented the once implementation procedure of commutation.Utilize steel plate that the α among the said structure figure, β, γ, θ rectangular area one are divided into four more separately, make whole drying machine cross section be divided into 16 rectangle sub-districts, the practical structures of each rectangle sub-district is a bias current funnel.The grain in α district and γ district can flow to β district and θ district respectively by funnel, and the grain in β district and θ district also flows to α district and γ district respectively through the funnel of its sub-district simultaneously.After once commutating, grain positional alignment from left to right is; β, α, θ, γ.
Fig. 5 has represented the implementation procedure of secondary commutation.This process only makes the grain occurrence positions that is in α and θ district exchange, and utilizes steel plate that the cross section in α district and θ district is divided into eight rectangle sub-districts, with the identical principle that once commutates the grain occurrence positions in these two zones is exchanged.After the secondary commutation, grain positional alignment from left to right is; β, θ, α, γ.
Fig. 6 has represented the implementation procedure of three commutations.Utilize steel plate that the drying machine cross section is divided into 16 rectangle sub-districts, the grain occurrence positions in these two zones is exchanged with the identical principle that once commutates.After three commutations, grain positional alignment from left to right is; θ, β, γ, α.
Fig. 7 has showed two reversing hopper structures of adjacent region on tempering commutation section cross section.The bias current funnel is suitable for reading to be rectangle, and outlet also is a rectangle, and leads to the bottom of adjacent area funnel.The size and the shape of these two funnels are just the same, are that the rotation symmetry is placed in the space.In the embodiment of Fig. 7, Fig. 8 and Fig. 9, each funnel is welded by header board (9), left plate (10), swash plate 1 (11), base plate (12), back plate (13), swash plate 2 (14), division board (15) and right plate (16).Unimpeded for guaranteeing that grain flows, the minimum angle-of-incidence in swash plate sideline should be greater than the natural angle of repose of material during enforcement.
