Description

Technical Field

[0001] The invention relates to the technical field of sandblasting waste recovery, in particular to a sandblasting waste efficient recovery and recycling system. Background Art

[0002] Sandblasting is a common surface treatment process that uses compressed air to generate a high-speed jet beam to spray material (such as quartz sand, iron sand, sea sand, garnet sand, corundum, copper ore sand, etc.) at high speed onto the surface of the workpiece to be treated, causing a qualitative change in the surface of the workpiece. It uses the impact of the high-speed sand flow to clean and roughen the substrate surface.

[0003] During the sandblasting process, sandblasting waste is generated. In traditional technology, some sandblasting machines use negative pressure extraction to suck away these sandblasting wastes to achieve the purpose of sandblasting waste recovery. However, in fact, the negative pressure extraction process accelerates the flow of air inside the sandblasting machine, which causes the abrasive sprayed by the sandblasting head to deviate, resulting in uneven sandblasting treatment on the workpiece surface and affecting the sandblasting quality. At the same time, the abrasive hits the workpiece surface at high speed, which generates a certain amount of heat, causing the waste temperature to rise. After these wastes are directly recycled, the temperature of the abrasive sprayed subsequently will be higher, affecting the surface treatment effect of the workpiece. Summary of the Invention

[0033] Working principle:

[0034] The sealed door of the sandblasting box 2 is opened, and the workpiece is placed between the two clamping plates 24. The driving cylinder 23 is started, and the piston end of the driving cylinder 23 moves with the clamping plates 24, so that the two clamping plates 24 clamp the workpiece. Then, the first feed valve on the outer surface of the first feed pipe 16 is opened, and the workpiece is sandblasted through the sandblasting head 17. During the sandblasting process, the sandblasting waste falls onto the receiving hollow plate 5.

[0035] Before sandblasting, open the second valve on the first air duct and start the air cooler 10. The cold air enters the interior of the second rotary tube 4 through the first air duct and then enters the interior of the fixed air bag 6 through the second rotary tube 4, so that the fixed air bag 6 expands after being inflated, and the fixed air bag 6 fits with the inner wall of the sandblasting box 2, greatly reducing the gap between the hollow plate 5 and the sandblasting box 2. At the same time, open the first valve on the first water pipe and start the first water pump 8. The first water pump 8 draws cold water from the outside into the first rotary tube 3 and then enters the interior of the hollow plate 5 through the first rotary tube 3 to reduce the temperature of the waste material on the surface of the hollow plate 5. At regular intervals, close the first valve on the first water pipe, open the first valve on the second water pipe, start the second water pump 9, and extract water from the hollow plate 5 to form regular water changes.

[0036] After a certain amount of sandblasting waste is received on the receiving hollow plate 5, the exhaust fan 11 is started first, and the exhaust fan 11 extracts the gas inside the fixed air bag 6, and then the servo motor 7 is started. The output shaft of the servo motor 7 rotates with the first pulley, so that the first rotating tube 3 turns 180 degrees with the receiving hollow plate 5, and the sandblasting waste on the receiving hollow plate 5 is poured down, and then the cold air blower 10 is started again to inflate the fixed air bag 6, and then the vibrator 13 is started to filter out the smaller waste residues in the sandblasting waste on the filter plate 12 and discharge them through the waste residue discharge pipe 14, and the negative pressure pump 20 is started to extract the filtered abrasive from the sandblasting box 2 through the extraction pipe 21, and the abrasive enters the interior of the abrasive recovery box 18 for collection, and the second feed valve on the second feed pipe 19 is opened regularly to allow the abrasive in the abrasive recovery box 18 to enter the interior of the abrasive box 15.
