Detailed Description
As shown in fig. 1, an air inlet of the nitrogen making device (1) is connected with a first port (201) of a three-way pipeline (2), a second port (202) of the three-way pipeline (2) is connected with an air outlet of a stop valve (3), an air inlet of the stop valve (3) is connected with a bottom pipeline of a warehouse (6) through an air-conditioning pipeline (5), a third port (203) of the three-way pipeline (2) is connected with an air outlet of an electric control valve (4), and an air inlet of the adjustable electric control valve (4) is communicated with air.
As shown in figure 1, an air inlet of the detection air pipe (7) is inserted into the grain pile, and an air outlet is connected with the micro-pressure sensor (8).
As shown in fig. 2, when the nitrogen is filled with the ring gas for adjustment, the air inlet amount of the nitrogen making device (1) entering the warehouse is fixed, so that the pressure in the warehouse can be adjusted by adjusting the air outlet amount of the warehouse (6). According to the bin internal pressure collected by the micro-pressure sensor (8), the opening degree of the adjustable electric valve (4) is automatically adjusted, when the bin internal pressure is higher, the opening degree of the adjustable electric valve (4) is smaller, the air sucked by the nitrogen making device (1) is smaller, the air outlet amount of the bin (6) is larger, and the bin internal pressure is reduced. Similarly, when the pressure in the bin is lower, the opening of the adjustable electric valve (4) is larger, the air sucked by the nitrogen making device (1) is more, the air outlet amount of the bin (6) is smaller, and the pressure in the bin is raised. Therefore, the pressure in the bin can be kept in a normal range all the time, and the automatic adjustment of the pressure in the bin is realized.
As shown in fig. 2, the stop valve (3) is automatically opened during the operation of the nitrogen gas filling ring air-conditioning, the gas in the bin enters the nitrogen making device (1) through the stop valve (3), and the nitrogen gas in the bin is automatically closed and prevented from leaking when the operation of the nitrogen gas filling ring air-conditioning is finished.
As shown in fig. 2, the micro-pressure sensor (8) is used for detecting the pressure in the bin, the detection points are arranged, and the detection air pipe (7) is inserted into the middle position of the grain pile in the bin to a depth which is half of the height of the grain pile, so that the detected pressure in the bin is accurate.
