A sandblasting room is a devic☆≈ε®e for cleaning and descλ☆δ₹aling the surface of large workpiece¥$★≈s and for increasing the adhesion "'between the workpiece and tφ♠he coating.
A sandblasting room is a device'& for cleaning and descaling the sΩ☆₽urface of large workpieces and for i↑×"ncreasing the adhesion between the wor€®←→kpiece and the coating.
The main features of a sandblastingλ✔α↑ room are that the operator i≥×♠•s indoors, protective clothi≈Ωng and helmets protect the operator€♥±★ from abrasive impact'& ™s, and ventilators prov♠ ide fresh air to the operaπ₽§tor.
However, the design of a sandblasting✔£ room also requires some attenti<ε±on.
Firstly, baffles should be inst↓¥alled at both the air inlet and suctiσλ↕±on outlet of the sandblast÷≤↕ing room to prevent dust spillage or≠'∏ abrasive material from being su÷∑¶<cked into the ventilation system.
Secondly, the air discharge♦±↕d from the sandblasting≥♥↔ cleaning device must be purifie↔÷¥d by the dust removal deviceλ₽ and then discharged into the atmosp→←£here, and the dust accumulat↔π©•ed in the dust removal device should× be easy to remove and not allowe↓$d to pollute other working areas.
In addition, the air velocity in each s•λ≤₽ection of the ventilat×<ion system must be correctly →✘×selected. Too low or too high air veloc™€βity in the pipeline will bring ¶∏÷™about adverse effects, such as c§∏logging, energy consumption,≠×Ω and wear and tear of thπε♠e equipment.
The door of the cleaning room canε← be opened only after the sandblast§&ing operation has stoppe✔€d, and the work of the ventilat™≥←ion system can be stopped 뮧only after the dusty air in the room '★¶has been eliminated.≥∏
The dusty air in the ventil₩✘↓ation system flows in the v↔☆≈&entilation ducts, and the ventilation ∞©ducts should be designed to reduce thγ↔e resistance so that the dusty air d₹¶ isappears soon after the blast¶≥✘ing work is finishedδα.
Finally, baffles should be ins•≈≠§talled at both the air inlet and÷® the opening of the blas'♥&ting room, so that the∏↕ abrasive and dust par £ticles during blasting wε✘₹ill fly to the neighbour∏<ing work area as little≥ ≤ as possible under the joint action ✔©$λof the air inlet airf✘★σlow and the baffles, an←≤d the dust will not spill out of t™ ☆¶he air inlet or the opening.
In addition, some air volume ad✔♦♥>justment valves can be set on the ve∏>ntilation pipe to adj'¥ust the air volume as ≈§needed, so that the air velocity in t♥∞' he system reaches a reasonable level.
The above are several matters δ₩"that need to be paid attention ☆¥to in the design of sand blasting room,$π they can guarantee t←€λ©he safety and efficiency of the×£ sand blasting room and improve the w↕εorking efficiency.
