Resin sand equipment is composed of magnetic separation belt conveyor, vibration crusher, centrifugal rotor secondary secondary machine, sand silo, bucket elevator (3 sets), mobile double arm continuous resin sand mixer, pulse back blowing dust collector and other equipment.
Process flow of resin sand equipment: the poured sand box and castings are hoisted to the inertia vibration sand dropping machine by crane. After sand dropping, the castings are transported to the shovel cleaning workshop, and the resin sand equipment sand box is transported to the sand box warehouse for standby. Large pieces of skin are clamped and the risers are manually sorted. The sand, sand balls and small pieces of cold iron passing through the sand falling grid fall to the magnetic separation belt conveyor. After magnetic separation, they are transported to the vibration crusher for crushing, film removal and screening. The screened sand enters the 1# bucket elevator and is lifted by the elevator to the centrifugal rotor secondary machine for strong and full film removal. The sand mixed with micro powder, dust and resin film flows into the flow curtain air separator through the quicksand trough. The air separator is connected with a cyclone and a pulse back blowing dust collector to remove the micro powder and dust. The sand is then lifted to the sand silo for standby by 2\\. The upper feeding port of the mobile double arm continuous resin sand mixer is connected with the sand outlet under the sand silo by the pneumatic ram. After pressing the sand mixing button on the control box of the sand mixing machine, the pneumatic ram will open automatically, and a fixed amount of sand will flow from the sand silo into the sand mixer. In the sand mixer, the sand is conveyed forward to the start end of sand mixing through the spiral plate, the curing agent is added from the near end control valve, and the resin is added to the rear near end valve after the small blades are stirred and premixed to enter the sand mixing end. After the curing agent, resin and sand are fully mixed, they are sent to the front discharge port and automatically flow into the prepared sand box for molding and core making.
