Double-pressure-tank shot generation system in shot blasting device

Abstract

The invention discloses a double-pressure-tank shot generation system in a shot blasting device. The double-pressure-tank shot generation system comprises a rack. The rack is sequentially provided with a cyclone separator, a vibrating screen, a storage hopper, an upper shot blasting tank and a lower shot blasting tank from top to bottom. An air closing machine is arranged between the cyclone separator and the vibrating screen. A feeding valve is arranged between the storage hopper and the upper shot blasting tank. A first sealing valve is arranged on the upper portion of the upper shot blasting tank. A second sealing valve is arranged on the upper portion of the lower shot blasting tank. The rack is further provided with a main gas supply pipeline. The main gas supply pipeline is communicated with the upper shot blasting tank and the lower shot blasting tank through an upper branch gas supply way and a lower branch gas supply way. A control valve is installed on the upper branch gas supply way. Air outlets are formed in the upper shot blasting tank and the lower shot blasting tank. According to the double-pressure-tank shot generation system in the shot blasting device, it can be ensured that shot blasting gas is not affected by the process of material changing of the upper shot blasting tank or the lower shot blasting tank, and continuity and stability of shot flow are ensured.

Description

technical field [0001] The invention relates to a shot peening equipment, in particular to a double pressure tank shot generating system in the shot peening equipment. Background technique [0002] Pneumatic shot peening equipment adopts double pressure tanks to realize continuous shot peening. The shot material of the pneumatic shot peening equipment is stored in the shot peening tank. When the shot peening operation is performed, the combined valve on the shot peening tank moves to lift the sealing valve on the shot peening tank and pressurize the shot blasting tank. At the same time, the shot valve under the shot blast tank is opened, and the booster valve is opened; like this, because the shot blast tank has been pressurized, the shot material enters the discharge port from the feed port of the shot valve The shot material at the feed port is accelerated; the accelerated shot air mixed flow passes through the shot blasting tube to the spray gun, and the shot material is...
