Because the bottom of the silo 400 is a tapered structure with a wide top and a narrow bottom, when powder falls from the discharge opening of the silo 400, the powder at the position of the discharge opening can fall rapidly, and the powder on the inner side wall of the silo 400 can stagnate, so that a central cavity, commonly known as a mouse hole in the industry, is formed in the silo 400, the depth of the mouse hole is deeper and deeper along with the continuous falling of the powder, once the mouse hole collapses, a huge impact force is caused to the bottom of the silo 400, and a fixed connection structure outside the silo 400 can be broken by impact in severe cases. For this, a plurality of air cannons 420 are annularly arranged on the conical bottom of the silo 400, in order to better break up the powder attached to the inner side wall of the silo 400, the number of the air cannons 420 is preferably four, the air cannons 420 can store compressed air, after a certain pressure or a certain time is reached, the electromagnetic valve of the air cannons 420 is opened, the compressed air sprayed from the air cannons 420 can break up the powder attached to the inner side wall of the silo 400, and the formation of a mouse hole is avoided. Since the air cannon 420 continuously injects external air into the silo 400, the air pressure in the silo 400 gradually increases, and the temperature in the silo 400 rises, in order to monitor the air pressure and the temperature in the silo 400, a temperature sensing device and an air pressure detection device are installed in the silo 400, and the temperature sensing device and the air pressure detection device are both in electrical signal connection with a central console of an operation room, so as to monitor the temperature and the air pressure in the silo 400 in real time. In order to discharge the gas in the silo 400, the top of the silo 400 is provided with an exhaust device (not shown in the drawing) for conventional exhaust and an explosion vent for instant air leakage.

In the powder blanking and loading process, gas in the tank car is discharged through the exhaust branch pipes 730, but a small amount of powder is mixed with the discharged gas, so that the powder is prevented from being directly discharged to the outside, the blanking and loading module further comprises a bag-type dust collector 800, the bag-type dust collector 800 is provided with a recovery bin 810, the recovery bin 810 is communicated with a fan 900, all the exhaust branch pipes 730 are communicated with an exhaust main pipe 731 together, and the exhaust main pipe 731 is communicated with the fan 900, so that the gas in all the exhaust branch pipes 730 is collected into the exhaust main pipe 731 and enters the recovery bin 810 through the fan 900. Be equipped with exhaust pipe 811 on retrieving the storehouse 810, the bottom of retrieving the storehouse 810 is the back taper, the lower extreme of retrieving the storehouse 810 is equipped with retrieves the mouth, it connects relevant wind ware 820 to retrieve the mouth, the exit of air seal machine 820 is connected with powder and collects bag 830. When the gas mixed with the powder enters the recovery bin 810, the powder is deposited at the bottom of the recovery bin 810 because the density of the powder is greater than that of the air, and the redundant gas is discharged from the exhaust pipe 811; when the air seal machine 820 is started, the powder at the bottom of the recovery bin 810 is conveyed into the powder collection bag 830, so that the recovered powder can be conveniently collected by a user.
