[0016] Marked as: flame detector 1, explosion suppressor 2, controller 3, temperature detector 4, audible and visual alarm 5, display and control terminal 6, nitrogen injection solenoid valve 7, silo 8. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present utility model will be further described below in conjunction with the drawings and the detailed description of the embodiments.

[0018] As Figure 1 shown, the explosion suppression system of the present utility model for a cotton powder silo includes a flame detector 1, an explosion suppressor 2, and a controller 3. The flame detector 1 is arranged on the side wall of the silo 8, and the probe of the flame detector 1 is located inside the silo 8. The explosion suppressor 2 is connected to the inside of the silo 8 through a connecting pipe;

[0019] The flame detector 1, the explosion suppressor 2, and the controller 3 are electrically connected. The electrical connection can be a wireless connection or a wired connection. For the sake of ensuring stability, the present utility model preferably uses a control cable for wired connection.

[0020] The flame detector 1 monitors the interior of the silo 8 in real time to detect whether there is a flame or explosion inside the silo 8. When a flame or explosion occurs inside the silo 8, the flame detector 1 can capture the flame and explosion signals within 5 seconds and transmit the signals to the controller 3. After the signals are analyzed and processed by the controller 3, the controller 3 drives the explosion suppression device 2 to operate. The explosion suppression device 2 is filled with a fire extinguishing medium. When the explosion suppression device 2 operates, it transports the fire extinguishing medium to the interior of the silo through a connecting pipe. The fire extinguishing medium deals with the flame and explosive substances, effectively handling the accident in the budding stage and improving the safety of use of the cotton powder silo 8.

[0021] Specifically, the function of the flame detector 1 is to monitor the interior of the silo 8 in real time to detect whether there is a flame or explosion inside the silo 8. To improve the monitoring effect of the flame detector 1, the number of flame detectors 1 is multiple, preferably 3 - 6. All the flame detectors 1 are evenly distributed in the upper middle part of the silo 8.

[0022] The explosion suppression device 2 is filled with a fire extinguishing medium, which is usually heptafluoropropane. When a flame or explosion occurs inside the silo 8, the flame detector 1 can capture the flame and explosion signals within 5 seconds and transmit the signals to the controller 3. After the signals are analyzed and processed by the controller 3, the controller 3 controls the explosion suppression device 2 to operate. When the explosion suppression device 2 operates, it transports the fire extinguishing medium to the interior of the silo 8 through a connecting pipe. The fire extinguishing medium deals with the flame and explosive substances. To improve the use effect of the explosion suppression device 2, the number of explosion suppression devices 2 is multiple, preferably 5 - 8. All the explosion suppression devices 2 are evenly distributed in the upper middle part of the silo 8, and the explosion suppression device 2 is located below the flame detector 1. For the convenience of using the connecting pipe, the connecting pipe is preferably a flexible pipe.

[0023] To further improve the safety of use of the cotton powder silo 8, for another example Figure 1 As shown, the present utility model is further provided with at least one temperature detector 4 and a nitrogen injection assembly. The temperature detector 4 is arranged inside the silo 8. The nitrogen injection assembly includes a nitrogen source and a nitrogen injection solenoid valve 7. The nitrogen injection solenoid valve 7 is arranged on the side wall of the silo 8. The nitrogen source is connected to the nitrogen injection solenoid valve 7 through a nitrogen pipeline. The temperature detector 4 and the nitrogen injection solenoid valve 7 are both electrically connected to the controller 3. The temperature detector 4 monitors the interior of the silo 8 in real time, monitors the temperature inside the silo 8, and transmits the detected temperature to the controller 3. When the temperature reaches the preset value of the controller 3, the controller 3 automatically controls the nitrogen injection solenoid valve 7 to open, and the nitrogen injection assembly injects nitrogen into the silo 8. Nitrogen can inhibit the combustion of the powder in the silo 8, further improving the safety of use of the cotton powder silo 8 and reducing the possibility of accidents.

[0024] For the convenience of use and to further improve the safety of use, for another example Figure 1As shown in the figure, the utility model is also provided with an audible and visual alarm 5 and a display and control terminal 6, and both the audible and visual alarm 5 and the display and control terminal 6 are electrically connected to the controller 3. When the temperature in the silo 8 reaches the warning value, the controller 3 controls the activation of the audible and visual alarm, and at the same time the display and control terminal 6 displays that the temperature of the silo 8 is abnormal, which is convenient for the staff to notice and alerts the staff.
