9. The small mold environment fumigating device for the local temperature anomaly point of the horizontal warehouse of the grain depot according to claim 1, wherein the small mold environment fumigating device for the local temperature anomaly point of the warehouse comprises more than one small mold environment fumigating device, and when the number of the small mold environment fumigating devices for the local temperature anomaly point of the warehouse is more than one, the small mold environment fumigating devices for the local temperature anomaly point of the warehouse are arranged around the heating point in concentric circles.
10. A method for fumigating a small mould environment at local temperature anomaly points of a horizontal warehouse of a grain depot, which is characterized in that the device of any one of claims 1 to 9 is utilized; the use comprises the following steps:
firstly, determining a heating point (6) which is a point position of part abnormal heating by using a grain condition temperature measuring system, and judging the point position as a mildew and insect infestation;
directly arranging a single tube at the periphery of the heating point (6);
the fumigation medicine is placed in an arc-shaped shell (23) with holes;
the down-extending pipe (21) is held by a hand to move downwards to the heating point (6), then the inflatable closed pipe (27) is inflated, the inflatable closed pipe (27) inflates the outer rubber ring (25), and the outer rubber ring (25) expands to extrude the inner wall of the single pipe (3);
the two closing plates (24) are oppositely provided with an isolation space, and the only position for ventilation with the outside is the hole of a single pipe of the closing section;
fumigating gas is emitted from the fumigating medicine and is emitted to the heating point (6) through the holes of the single pipe of the closed section to remove mould at a fixed point and cool;
a small 10-watt fan promotes the fumigation medicine to generate fumigation gas;
the non-porous pipe (5) which is close to the grain surface and is provided with a plurality of screw threads for connection can prevent the fumigation medicine in the grain gap from being directly diffused to the grain surface along the non-porous pipe (5);
after the fumigation is finished, the temperature of the grain at the heating point is reduced, the single pipe is taken out, and all parts are disassembled.
