Through the multifunctional control box, it can cooperate with the wind circulation system and the sealed warehouse body to realize various operation modes, thereby improving the nitrogen filling efficiency, saving time and reducing costs.

[0055] After research, the nitrogen filling process is as follows:

[0056] Preparation stage before starting nitrogen filling:

[0057] First, check the status of the door and window vents to confirm that they are closed. Use the upper discharge mode to discharge the air pressure in the sealing film to -350Pa, close all valves, start timing from -300Pa, and wait for the air pressure to drop to -150Pa to calculate the half-life. If it reaches more than 300 seconds, start nitrogen filling. Otherwise, WeChat push notification will be sent to the user to take corresponding measures. The upper discharge mode is to open valve 1, valve 3 and the circulation fan, close other valves, and the airflow on the upper part of the sealed warehouse body is discharged through the circulation fan;

[0058] The first step of the first stage of nitrogen filling is to use the upper filling mode to form a high-concentration nitrogen sealing film in the warehouse; the maximum pressure of the sealing film does not exceed 300Pa. The upper filling mode is to open valve 5, close other valves and circulation fans, and start the green insecticide gas station;

[0059] The second step of the first stage of nitrogen filling is to use the upper filling and lower exhaust mode to extract the air in the grain pile from the bottom, so that the high-concentration nitrogen in the sealing film sinks into the grain pile until the sealing film is exhausted and negative pressure appears again. At this time, analyze the data of each sampling point. If a sharp drop is found, stop the operation and notify the user via WeChat to handle the abnormality. If everything is normal, the average concentration of the sampling points in the warehouse should reach more than 93% after this round; you can repeat another round to make the average concentration reach more than 95%. The upper filling and lower exhaust mode is to open valves 5, 4, and 3, start the circulation fan, start the green insecticide gas station, and close other valves;

[0060] The first step of the second stage of nitrogen filling is that after the first stage, the nitrogen concentration at the highest point of the sampling point will reach more than 97%, and the lowest point will reach more than 93%. At this time, the downward filling mode is adopted until the sealing membrane is filled again. The downward filling mode is to open valve six, close other valves, turn off the circulation fan, and turn on the green insecticide gas station;

[0061] In the second step of the second stage of nitrogen filling, the highest point of the sampling point will reach more than 98% and the lowest point will reach more than 96%. At this time, it is necessary to compare the nitrogen concentration of the upper sealing membrane with the nitrogen concentration at the lower pipeline module to specifically select the lower discharge mode or the upper discharge mode, or compare the internal circulation mode after a period of time, and then empty it again. The lower discharge mode is to close valve five, valve two, green sterilization gas station, valve one, open valve three, valve four, and circulation fan. The upper discharge mode is to open valve one, valve three, circulation fan, close other valves, and close the green sterilization gas station. The internal circulation mode is to close valve five, valve six, valve three, valve four, green insecticide gas station, and open valve one, valve two, and circulation fan.

[0062] In the third stage of nitrogen filling, after the above two stages, the highest point of the sampling point will reach more than 99%, and the lowest point will not be lower than 97%. At this time, start to circulate while filling until the sealing membrane is filled again to complete the operation. The mode of circulating while filling is to close valve six, valve four, and valve three, and open the green insecticide gas station, valve one, valve two, valve five, and circulating fan.

[0063] Through nitrogen filling and circulation, nitrogen can be evenly filled into the gaps in the grain pile, reducing nitrogen filling costs and improving nitrogen filling efficiency.

An insect hole is opened on the wall of the cover body, and the cover body is glued and fixed to the end plate and the cone cap. The pest trapping device can be inserted downward into the grain pile to trap deep pests. By controlling different solenoid valves 2, pest trapping devices at different positions can be detected, thereby improving monitoring accuracy. Insect attractants are installed in the cover body, and controller 2 621 is installed in shell 2.

A controller 703 is installed in the shell. The controller is connected with a vacuum pump, a refrigerator, a solenoid valve, and a temperature detection device. Signal connection. During use, the temperature detection device detects that the wall temperature reaches the preset value and feeds back to the controller. The controller controls the air cooler and the vacuum pump to start. The controller also controls the corresponding solenoid valve to start, and controls the cooling coil at the corresponding position to work. The control accuracy is high and the energy consumption is low. During the grain storage process, the rapid cooling with a temperature difference exceeding 8°C will cause condensation. The temperature and humidity in the temperature control chamber can be detected by the temperature sensor. When the temperature is lower than the preset value, an alarm is triggered. The temperature in the temperature control chamber is adjusted by adjusting the air inlet door. To facilitate the temperature adjustment, a valve can be installed on the pipe between the air cooler and the temperature control chamber to adjust the valve opening and thus control the air volume.

A filter is also installed at the air inlet end of the green insecticide gas concentration detection tube. The advantage is that the type of pests can be observed through the glass bottle, and the disadvantage is that the insect bottle needs to be cleaned regularly. A controller three 56 is also installed in the carriage. The controller three is connected to the green insecticide gas generator and the pest detection device two signals. The pest situation in the sealed warehouse is regularly detected through the pest detection device one. The concentration of green insecticide gas can also be detected. When pests are found or the concentration of green insecticide gas is lower than the preset value, an alarm is triggered. The mobile green insecticide gas station is transported to the granary and connected to the multi-functional control box. The pests and the concentration of green insecticide gas are detected again through the pest detection device two. After verification, the cause is found and the nitrogen is refilled.

[0068] The granary body is located on the upper side of the sealed silo body and is equipped with a heat exhaust fan 3 and an air conditioning unit.
