With the innovation of intelligent shot blasting and rust removal, its core technology is reflected in: realizing the self-locking of the equipment in sequence, frequency conversion and energy saving of the shot blasting motor, setting the sand amount according to the pipe diameter, cleaning the shot sand by the air washing system, quick replacement specifications of the pin type, etc., and the three-level dust removal and environmental protection standards. Lack of steel sand reminder: automatic reminder when the hoist is short of steel sand, automatic reminder when the sand storage bucket is short of steel sand, automatic reminder when the shot blasting machine is free of steel sand; Open the lock in sequence: open the shot sand separator, open the elevator, open the shot blast 1, open the shot blast 2, open the sand valve. Fast sand lock: the speed of steel sand sand is too fast, which will cause the shot blasting machine to block the current multiplication and burn the motor. The one-step spraying and winding insulation pipe equipment of Walstar can automatically control the sand amount, and the motor can run with frequency conversion to save electric energy. Steel sand cleaning program: rust removal to remove the ineffective steel sand and oxide, steel sand through the air washing system in the process of steel sand circulation; Dust treatment scheme: the steel sand after rust removal passes through the first-level sand reduction chamber, the second-level cyclone dust collector, and the third-level filter drum dust collector, and the filtered air meets the national emission standards for drainage.
