Specific embodiment
Embodiment, as shown in Figure 1 and Figure 2, a kind of cooling structure of grain heat-drying uniform high-efficiency, including two cooling sections,
Horn shape box 4, duct set road 6, blower 7.
Described two cooling sections are respectively the first cooling section 1 and the second cooling section 2, and it is cooling that the first cooling section 1 is located at second
The upper layer of section 2, the first cooling section 1 are connected with bolt with pedestal grain discharging section with the second cooling section 2 by modular construction.
The flange on the first cooling section 2 of cooling section 1, second is bolted in the duct set road 6.
The blower 7 passes through duct set road 6 from horn shape box 4 the cold air in atmosphere, sucks in drying tower to reach
Cooling purpose, due to being air draught（Negative pressure）So can recycle to grain bring high-temp waste gas, both guarantee cooling time
And high-temp waste gas recovery processing can be carried out, and exhaust gas is expelled back into again in the cooling section of top by the air-breathing of blower 7, it is secondary
It utilizes, the heat put aside when cooling down waste gas absorption grain drying.
Described first cooling section 1 is by the way of Two In and One Out, and the first cooling section 1 includes three row horn shape boxes 4, wherein two rows
Horn shape box is horn-shaped air inlet box, and in addition a line horn shape box is air draft horn shape box, every every row air draft horn shape box of row horn-shaped air inlet box ratio
One few, preferred every row horn-shaped air inlet box is 7 horn shape boxes, and every row air draft horn shape box is 8 horn shape boxes.
Described second cooling section 2 is by the way of one-in-and-two-out, and the second cooling section 2 includes three row horn shape boxes 4, wherein a line
Horn shape box is horn-shaped air inlet box, and in addition two behavior air draft horn shape boxes, every row horn-shaped air inlet box are one fewer than every row air draft horn shape box,
Preferred every row horn-shaped air inlet box is 7 horn shape boxes, and every row air draft horn shape box is 8 horn shape boxes.
The structure of described first cooling section 1 and the second cooling section 2 using intermediate single air duct, the double way to move grains in two sides, two coolings
Section accumulation gets up to have three row air draft horn shape boxes, and three row horn-shaped air inlet boxes are symmetrically distributed in air duct two sides, is used based on experimental data
Enterprising lower row is interlocked reasonable Arrangement.Mixed flow ventilation, reduces discharge speed by every row horn-shaped air inlet box one fewer than air draft horn shape box
Degree increases the cooling time contacted with grain, can cool down to grain rapidly.
The horn shape box is unique short conical surface shape, by verification experimental verification, the reasonable Arrangement made of arranging to it, and short
Conical surface horn shape box and grain contact area are big；Horn shape box uses enterprising lower row's interlaced arrangement, mixed flow ventilation, every row horn-shaped air inlet box
One fewer than air draft horn shape box, mass rate of emission is reduced, increases cooling time, can cool down to grain rapidly, thus can
Guarantee is made with the uniform high-efficiency drying to grain.
