Title: Air stream conveyer
Inventor: TANIKAI MICHIO
IPC: B08B6/00
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To protect a treatment object from the adhesion of particles in a conveying passage, by a method wherein, while an air stream is jetted out a dust collecting electrode and a dust removal object surface are made to come close to each other and, further, voltages are applied between a conveying surface and the dust collecting electrode and between a conveying passage wall and the dust collecting electrode. SOLUTION: A conveying passage wall 1b and a dust collecting electrode 3 are made to come close to a conveying surface 1a and an air stream is jetted out from a jet hole 4. The voltages are applied between the dust collecting electrode 3 and the conveying surface 1a and between the dust collecting electrode 3 and the conveying passage wall 1b. As a particle dust removal object surface is an insulating layer and particles are in a state floating from the base metals of the conveying surface 1a and the conveying route 1b, various influential forces are weakened, and the particles are easily removed from the conveying surface 1a and the conveying passage wall 1b by an electrostatic force and reach the dust collecting electrode 3. As the dust collecting electrode 3 has a large surface resistivity, the induction re-scattering can be avoided and the particles are securely captured.  With this constitution, a dust collection operation can be performed without opening the conveying passage to the atmosphere and the particles in the conveyer can be securely removed.
