Detailed Description

The utility model will be further described with reference to the accompanying drawings.

As shown in fig. 1-3, a soil detection sample drying device comprises a ventilation piece 1, wherein two ends of the ventilation piece 1 are respectively provided with a fan 2 and a sample bin 3 in a communication mode, the sample bin 3 is used for placing a sample to be dried, and air flow from the fan 2 passes through the ventilation piece 1 and enters the interior of the sample bin 3; an air flow guide piece 4 is arranged in the air exchange piece 1, a plurality of air homogenizing channels 5 are arranged in the central area of the air flow guide piece 4, an exhaust channel 6 is arranged on the side wall of the air exchange piece 1, and air flow from the fan 2 passes through the air homogenizing channels 5 to enter the sample bin 3 and flows back to the vicinity of the exhaust channel 6 along the side wall of the sample bin 3 to be discharged; an air heating element 8 is arranged in the fan 2, and the opening of the exhaust channel 6 is adjustable.

As can be seen from the figure, the ventilation member 1 is connected with the device base as a mounting base for other components; referring to fig. 2, the fan 2 is specifically driven by a motor to rotate a blade, and sucks air above the drying device into the ventilation member 1 as an initial air flow a; then the air flow a passes through the air homogenizing channel 5 to enter the sample bin 6 as air flow b under the action of the driving force of the blades, the air flow b contacts with a sample to be dried in the sample bin 6, the air flow b is scattered on the surface of the sample to be processed, air flow c is generated after the air flow b encounters the blocking, the air flow c takes away the moisture in the sample to be dried, finally the moisture returns to the ventilation member 1 from the space around the air flow b, and the moisture is blocked by the edge part of the air guide member 4 and is discharged at the air discharge channel 6; an air heating element 8 is arranged in the fan 2, and the heating end of the air heating element is positioned near the rotating blades and can heat the passing air, so that the drying speed is improved;

by arranging the air homogenizing channel 5 in the central area of the air flow guide 4, the air flow b playing a drying role can flow in the center, so that the surrounding space is reserved for the flowing of the air flow c with backflow, the generation of turbulent flow is reduced, the ventilation process is smoother, and the improvement of the drying efficiency is facilitated; the opening of the exhaust channel 6 can be controlled by arranging a movable baffle, installing a valve and the like, so that one part of the returned air flow c is exhausted, and the other part of the returned air flow c returns to the sample bin 3 along with the air flow b to participate in drying repeatedly; the opening of the exhaust channel 6 is specifically adjusted according to the water content of the sample, when the water content of the sample is large, the air flow is enough lubricated after one drying cycle, and at the moment, the opening of the exhaust channel 6 is adjusted to be large, so that the air flow carrying enough water is directly discharged; when the water content of the sample is smaller, the air flow is drier after one-time drying circulation, and the opening of the exhaust channel 6 is reduced at the moment, so that most or all of the air flow participates in the drying process again, thereby avoiding heat waste and having excellent energy-saving effect.
