The utility model discloses a concrete working process as follows:

this auto sucking machine's material tuber pipe 7 passes through the pipe connection feed mechanism, behind the pneumatic fan 15, because 3 intercommunication fans 15's air intake 1501 and bung 10 of exhaust column, the fan 15 takes out the gas in the filter vat 8, produce the negative pressure in filter vat 8, the atmospheric pressure that material tuber pipe 7 was located filter vat 8 one side this moment is less than the atmospheric pressure of outside feed mechanism one side, again because feed mechanism and feed bin intercommunication, make the material follow the air current and inhale feed mechanism from the feed bin, the air current still continues forward inflow filter vat 8, filter core 9 in the filter vat 8 blocks the dust, prevent that the dust from getting into fan 15, consequently, the air outlet 1502 of fan 15 can not discharge the air current that has a large amount of dust, can not influence the production environment.

When the filter element 9 blocks a certain amount of dust, the filtering capacity of the filter element is reduced and even the filter element is possibly blocked, the outlet solenoid valve 6 and the inlet solenoid valve 11 are periodically opened to make high-speed airflow blow into the filter element 9 from the air storage tank 14, and the filter layer 902 of the filter element 9 and the vent hole on the shell 901 are cleaned and dredged. At this time, the vacuum breaking device 2 needs to be closed to prevent dust from entering the fan 15.

When the gas storage capacity in the gas storage tank 14 is insufficient, the external gas source flows through the gas pipe 4 and enters the gas storage tank 14 through the gas supplementing opening 1402, and the gas supplementation is completed. A ball valve is arranged at a pressure relief opening 1401 at the bottom of the air storage tank 14, when the air pressure in the air storage tank 14 is too high, the ball valve is opened, part of air in the air storage tank 14 is discharged, the air pressure returns to a safety value, then the ball valve is closed, and the air storage tank 14 works normally.

The vacuum breaking device 2 comprises an air cylinder and a control valve, the blockage of the exhaust pipe 3 is controlled through the movement of the head of the air cylinder, and the delayed movement of the air cylinder is realized through the control valve.
