The hot air drying is a drying method which makes a heating medium (air, inert gas, fuel gas waste gas or other hot gas) directly contact with solid particles to be dried and makes the solid particles to be dried suspended in a fluid, so that the contact area of two phases is large, the heat and mass transfer process is enhanced, and the hot air drying method is widely applied to the operation of a drying unit of energetic materials. In the hot air drying process, due to the loss of moisture in the energetic material, static electricity generated by friction, collision and extrusion of the material in the moving process is released everywhere, so that the accumulation of static electricity is easier, and once the electrostatic discharge phenomenon occurs, disasters such as combustion and explosion of the energetic material are easily caused. Therefore, the method measures the quantity of the electrostatic charge in the process, grasps the electrostatic electrification rule of the material, further takes corresponding control measures, and has important significance for the safe production of the energetic material. At present, the measurement of the electrostatic charge amount in the hot air drying process of the energetic material mainly adopts a discontinuous material taking mode, and a Faraday cylinder method is utilized for testing, and the testing method has the following defects:

1. manual material taking on a production line is needed, so that the safety risk of personnel is high;

2. the saturated electrostatic charge quantity of the energetic material cannot be accurately measured under the influence of the material taking position of a production line and manual intervention;

3. the measured mass of the material cannot be weighed in real time.

4. The detection process is relatively cumbersome.

The technical problem to be solved by the invention is as follows:

1. the device capable of realizing the circulating hot air drying is designed, so that the material can automatically enter an air box to continuously dry the hot air after being subjected to the static detection, and the aim of measuring the saturated static charge quantity of the material is fulfilled;

2. the whole-process automatic remote control is adopted, man-machine isolation is realized, and the safety risk of personnel is reduced;
