Abstract
The invention discloses a non-power grain drying mechanism in the field of drying units, which comprises a feeding section, a drying section and a discharge opening, wherein the feeding section is arranged on the upper part of the drying section; the lower part of the drying section is provided with the discharge opening; the drying section is a cone with a large upper part and a small lower part; the drying section comprises an inner conical screen and an outer conical screen which are arranged coaxially and densely provided with screen holes; and the center of the feeding section is provided with an air inlet pipe of which the lower end is in sealed connection with the upper end of the inner conical screen through a transitional connecting piece. The inner conical screen and the outer conical screen are arranged coaxially to ensure that contact time of grain and hot air is the same, so the water reducing extent is equal and the moisture uniformity after the grain drying is improved; meanwhile, the drying section has the conical structure with the large upper part and the small lower part, so that the grain can be discharged from the drying section by means of gravity, mechanical power does not need arranging, and the grain does not undergo the mechanical stirring and high-speed friction to effectively reduce the breakage of the grain and ensure the quality of the dried grain.
Description
Technical field
The present invention relates to a kind of drying unit of grain.
Background technology
Present drying plant generally includes grain storage layer, baking zone and discharge layer, the grain storage layer is arranged on the top of baking zone, baking zone is a square structure, the baking zone below is provided with the discharge layer, the same section of described discharge layer is provided with a plurality of discharge mechanisms, is provided with total discharge mechanism below a plurality of discharge mechanisms.There is following shortcoming in this mechanism: 1, guarantee that surely its running status is unified because a plurality of discharge mechanisms differ when fabrication and installation, cannot say for sure that demonstrate,proving grain evenly descends, this just influences the drying effect of material, and the final moisture content unevenness increases.2, because of repeatedly being subjected to mechanical turning effort, material is broken because of a large amount of extruding increase, and has a strong impact on baking back quality.3, because be provided with a plurality of discharge mechanisms, increased power, energy consumption is big.
Summary of the invention
The present invention provides a kind of non-power grain drying mechanism, makes simply, can make that grain is evenly dried, percentage of damage is low, and not have mechanical energy consumption.
For addressing the above problem, the present invention is achieved in that
Non-power grain drying mechanism, comprise feed zone, oven dry section and discharge gate, feed zone is arranged on the top of oven dry section, discharge gate is arranged on the below of oven dry section, the taper that the oven dry section is big up and small down, described oven dry section comprises the inner conical sieve and the male-tapered sieve of coaxial setting, is densely covered with sieve aperture on inner conical sieve and the male-tapered sieve; Described feed zone center is provided with blast pipe, and blast pipe lower end and inner conical sieve upper end are tightly connected through the transition connector.
During work, the annular space that material is formed by the barrel and the blast pipe outer wall of feed zone enters in the drying channel that inner conical sieve and male-tapered sieve constitute, and relies on gravity evenly mobile, is discharged by discharge gate again.Hot blast is entered on the inner conical sieve by blast pipe, under the effect of hot-blast pressure, passes the inner conical sieve and enters in the drying channel, and discharge from the male-tapered sieve.Finish the wet exchange of heat when hot blast passes drying channel, take away grain moisture content.Grain flows from top to bottom, finishes grain heat-drying.Because inner conical sieve and male-tapered are sieved coaxial setting, hot blast can evenly distribute on the horizontal section of each drying channel, guaranteed that the time that grain contact with hot blast is identical, thereby precipitation range is equal, has improved the water uniformity after grain dries by the fire.Because the big up and small down pyramidal structure of oven dry section makes grain can rely on gravity just can discharge outside the baking zone, need not to be provided with power simultaneously, grain effectively reduces the fragmentation of grain not through mechanical agitation and high-speed friction, has guaranteed the quality of oven dry grain.
As further optimization of the present invention, described transition piece is up-small and down-big taper, and the hot blast flow velocity is reduced, be evenly distributed on the inner conical sieve around, increased the uniformity of grain heat-drying.
As further optimization of the present invention, the rounded or polygon in cross section of described inner conical sieve and male-tapered sieve.This regular shape, easily manufactured.
As further optimization of the present invention, connect by gripper shoe between described inner conical sieve and the male-tapered sieve, strengthen the intensity of inner conical sieve and male-tapered sieve.

The specific embodiment
Be a kind of non-power grain drying mechanism as shown in Figure 1, 2, 3, comprise feed zone 3, oven dry section 4 and discharge gate 5, feed zone 3 is arranged on the top of oven dry section 4, discharge gate 5 is arranged on the below of oven dry section 4, the taper that oven dry section 4 is big up and small down, oven dry section 4 comprises the inner conical sieve 4-1 and the male-tapered sieve 4-2 of coaxial setting, the cross section of inner conical sieve 4-1 and male-tapered sieve 4-2 is rounded, connect by gripper shoe 4-3 between the two, also be densely covered with sieve aperture on inner conical sieve 4-1 and the male-tapered sieve 4-2; Feed zone 4 centers are provided with blast pipe 1, and the transition piece 2 of blast pipe 1 lower end and inner conical sieve 4-1 upper end through being up-small and down-big taper is tightly connected.
The present invention is not limited to the foregoing description, and the cross section of described inner conical sieve 4-1 and male-tapered sieve 4-2 can also be regular polygon.
