A sandblasting room is a ♣∏device for cleaning and descaling t↕≤he surface of large workpieces a£©®nd for increasing the a&©←dhesion between the workpiece and>↔ the coating.
The main features of∑" a sandblasting room a' ✔re that the operator is indoors, ¶←protective clothing and helmets protec∏≤®£t the operator from a§↓♠brasive impacts, and ventilators provid φ×∏e fresh air to the operator.
However, the design of a sandb<∑→lasting room also require≠♦<s some attention.
Firstly, baffles should bΩ♠&γe installed at both the air inlet §©©and suction outlet of the sandblasting ₽₽room to prevent dust spil¥•lage or abrasive materiaε↑∏l from being sucked into the ve $•ntilation system.
Secondly, the air discharge≤Ωd from the sandblasting cleaning devi&εce must be purified by the du&×st removal device and then discharge→β¶d into the atmosphere, a>™σλnd the dust accumulated♦ ¥× in the dust removal device§♥× should be easy to remove and not π∞≤ allowed to pollute other α™γworking areas.
In addition, the air velocity in each s♥Ωection of the ventilati€™on system must be correctly se €✔lected. Too low or too high air veloci↔$©→ty in the pipeline will bring about a₹↕↕dverse effects, such as clogging, enerαεδgy consumption, and wear and te↓×ar of the equipment.
The door of the clea₹←•÷ning room can be opened only after t♣•↔÷he sandblasting operation has sto¥↑ pped, and the work of the ventil✔₹∏ation system can be stopped on♠∏ly after the dusty air in ₹♠±the room has been eliminated.
The dusty air in the ventilation syst✔✔βem flows in the ventilation ducts, and"→ the ventilation ducts shoul<×☆d be designed to redu™$≈ce the resistance so tλ××hat the dusty air dis←§ ≠appears soon after t'∑♥γhe blasting work is finished.≥α£
Finally, baffles should be installed¶<≠ at both the air inlet and the op¶ ening of the blasting room, so t×☆₽hat the abrasive and dust pa>$rticles during blasting will fly to the§₽λ♣ neighbouring work area as little as ¥☆εεpossible under the joint action of tε<±he air inlet airflow and the baffles♠★, and the dust will n₹λot spill out of the air inlet or>$ the opening.
In addition, some air v₹£♦olume adjustment valves can be s $←αet on the ventilation pipe to adjust ÷Ωthe air volume as need≥★™♦ed, so that the air velocit₹'γ★y in the system reac€→★>hes a reasonable level.
The above are several matters th₽₩at need to be paid attention to in ∞ ≤the design of sand blasting roo>Ωm, they can guarantee the safety an↓♠γd efficiency of the sa"λnd blasting room and improve the working efficiency.
