The invention belongs to the technical field of
metal rust removal
processing, and relates to an automatic shot blasting steel shot recovering device in a steel
pipe. The primary structure of the device comprises a front active plate, a rear fixing plate, a runner gland, a runner inner ring, a runner outer ring, a sandplow base, a traveling wheel, a blast wheel trolley, a
high pressure fan, a blast wheel rod, a fan gas
pipe, an alignment vehicle, a roller device, a sanding controller, a workpiece alignment tube, a transmission vehicle, a direct blast wheel, a
conveyor belt and the like. All parts are processed and assembled into the integral steel shot recovering device based on the
structural principle of the conventional sand throwing mechanism; and the integral steel shot recovering device is divided into a striking-off unit, a runner unit and a traveling unit according to the functions. The steel shot and a
rust dust shipping mechanism consists of the blast wheel trolley, the alignment vehicle and the transmission vehicle. The steel shot recovering device has the advantages of reliable principle, convenient use and installation, high
recovery rate, low cost, which is used for removing
rust of the inner wall of the various steel pipes.
