Abstract

The utility model provides a grain dryer which is simple in structure, convenient in operation and use and high in quality of the dried grain, and comprises a feeding hole, a drying bin and a discharge hole, wherein the feeding hole is arranged above the drying bin; the discharge hole is positioned under the drying bin; the grain dryer is characterized in that the drying bin is in a cone shape which is larger at the upper part and smaller at the lower part, and comprises an inner cone-shaped sieve, an outer cone-shaped sieve and a dustproof protective cover which are arranged in a coaxial way; the inner cone-shaped sieve and the outer cone-shaped sieve are respectively and densely covered with sieve meshes; reversing support plates are arranged between the inner cone-shaped sieve and the outer cone-shaped sieve alternately; and the reversing support plates are vertical to the inner cone-shaped sieve and the outer cone-shaped sieve.

Description

A kind of grain drier
Technical field
The utility model belongs to the drying plant field, is specifically related to a kind of grain drier.
Background technology
Grain drier is stored up at grain, play important effect in the grain processing.But grain drier in use tends to occur the uneven phenomenon of precipitation, and its main cause has two: 1) between the different grain layer, owing to receive the sequencing of hot blast different; Contact the grain layer quick heating of hot blast earlier; Precipitation range is big, and the grain layer of back contact hot blast heats up slow, and precipitation range is little; 2) because the skewness weighing apparatus of hot blast in drying machine, in same grain layer, the grain of the diverse location precipitation that is heated is also inhomogeneous.Like this, will occur between the different grain layers, with inhomogeneous, the uneven situation of precipitation of being heated between the layer grain diverse location, serious meeting produces part grain overdrying has the burnt grain of sticking with paste, and influences follow-up grain deep processing quality; Part grain is wet excessively to have half-cooked, grain security is stored stay hidden danger.Grain heat-drying precipitation non-uniform phenomenon ubiquity all in concurrent-countercurrent drying machine, mixed flow drying machine and cross flow drying machine.And these several kinds of towers are the main tower of grain heat-drying.
In recent years, there are some corresponding mechanisms to alleviate this problem, but all not ideal enough, like the grain commutator of cross flow drying machine, can only regulate in a direction, there is the not smooth problem of grain circulation in commutator; Also have a kind of spiral commutator, although can change the direction of grain, its drawback has: 1) need power, this can increase the cost of grain per ton undoubtedly; 2) complex structure needs regularly to protect buckwheat, maintenance; 3) increase the fragmentation of grain, because of screw conveyor belongs to higher a kind of of percentage of damage in conveying equipment.
Summary of the invention
The purpose of the utility model be to overcome the deficiency that exists in the prior art and provide a kind of simple in structure, easy for operation, the oven dry the high grain drier of grain quality.
The purpose of the utility model realizes like this:
A kind of grain drier comprises charging aperture, the oven dry storehouse; Discharge gate, said charging aperture are arranged on top, said oven dry storehouse, and said discharge gate is arranged on below, said oven dry storehouse; It is characterized in that; The taper that said oven dry storehouse is big up and small down comprises that inner conical sieve, the male-tapered of coaxial setting sieved and dust cover, is densely covered with sieve aperture on said inner conical sieve and the said male-tapered sieve; Be arranged alternately the switching-over gripper shoe between said inner conical sieve and the said male-tapered sieve, said switching-over gripper shoe is perpendicular to said inner conical sieve and said male-tapered sieve.
As the further optimization of the utility model, said discharge gate comprises material outlet and impurity outlet.
The beneficial effect of the utility model is embodied in:
1, pyramidal structure makes grain can rely on gravity just can discharge outside the baking zone, need not to be provided with power.
2, grain effectively reduces the fragmentation of grain not through mechanical agitation and high-speed friction, has guaranteed the quality of oven dry grain.
3, be provided with dust cover, reduce environmental pollution, impurity gets into the annular space of male-tapered sieve and dust cover formation with air-flow, discharges from the impurity outlet afterwards.
4, the utlity model has cost low, simple in structure, do not need repairing; The switching-over gripper shoe can two-way change grain the position, can make that grain crackle rate after the baking is low, fire damage is few, percentage of damage is low, not have burnt advantage of sticking with paste grain, no half-cooked high-quality grain.
Description of drawings
Figure l is the structural representation of the utility model;
Fig. 2 is the partial schematic diagram in the utility model oven dry storehouse;
Wherein: charging aperture 1, oven dry storehouse 2, inner conical sieve 3, male-tapered sieve 4, dust cover 5, sieve aperture 6, material outlet 7, impurity outlet 8, switching-over gripper shoe 9.
The specific embodiment
Basis is novel further specifies below in conjunction with 1,2 pairs in accompanying drawing:
A kind of grain drier comprises charging aperture 1, oven dry storehouse 2; Discharge gate, said charging aperture 1 are arranged on 2 tops, said oven dry storehouse, and said discharge gate is arranged on 2 belows, said oven dry storehouse; It is characterized in that; The taper that said oven dry storehouse 2 is big up and small down comprises inner conical sieve 3, male-tapered sieve 4 and the dust cover 5 of coaxial setting, is densely covered with sieve aperture 6 on said inner conical sieve 3 and the said male-tapered sieve 4; Be arranged alternately switching-over gripper shoe 9 between said inner conical sieve 3 and the said male-tapered sieve 4, said switching-over gripper shoe 9 is perpendicular to said inner conical sieve 3 and said male-tapered sieve 4.
As the further optimization of the utility model, said discharge gate comprises material outlet 7 and impurity outlet 8.
During work, material is got in the drying channel that inner conical sieve 3 and male-tapered sieve 4 constitute by charging aperture 1, relies on gravity evenly to flow, and is discharged by discharge gate again.Hot blast gets into oven dry storehouse 2, under the effect of hot-blast pressure, passes inner conical sieve 3 and gets in the drying channel, and discharge from male-tapered sieve 4.Accomplish the wet exchange of heat when hot blast passes drying channel, take away grain moisture content and impurity.Grain flows from top to bottom, and process switching-over gripper shoe 9 makes grain change to another position by original position and direction and direction realizes being heated evenly, the multiaspect oven dry.Because inner conical sieve 3 sieves 4 coaxial settings with male-tapered, 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 oven dry storehouse 2 big up and small down pyramidal structures make 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.

Claims (2)

1. a grain drier comprises charging aperture, the oven dry storehouse; Discharge gate, said charging aperture are arranged on top, said oven dry storehouse, and said discharge gate is arranged on below, said oven dry storehouse; It is characterized in that; The taper that said oven dry storehouse is big up and small down comprises that inner conical sieve, the male-tapered of coaxial setting sieved and dust cover, is densely covered with sieve aperture on said inner conical sieve and the said male-tapered sieve; Be arranged alternately the switching-over gripper shoe between said inner conical sieve and the said male-tapered sieve, said switching-over gripper shoe is perpendicular to said inner conical sieve and said male-tapered sieve.
