  • the invention has for its object to provide a waste sorting system of the type mentioned, in which the sorting staff is constantly supplied with clean air without drafts.
  • this object is achieved in that the manual picking workplaces, the discharge containers and the corresponding section of the conveyor belt are surrounded by a common housing, each manual release being at least one large-area fresh air supply outlet in the lower area thereof and one exhaust air inlet in the upper area, which is inserted into a continuous exhaust hood running parallel above the conveyor belt.

Abstract

L'invention concerne une installation de triage de déchets, destinée en particulier à un dispositif de compostage de déchets biologiques, et conçue pour trier des substances indésirables présentes dans ces déchets. Les matières collectées transmettant des nuisances olfactives ou des substances polluantes à l'air ambiant sont acheminées sur une bande transporteuse (1) devant des postes de triage manuel (4) munis de récipients de collecte adjacents (5). En vue de l'alimentation en permanence en air propre du personnel chargé du tri (16), les postes de triage manuel (4), les récipients de collecte (5) ainsi que la partie correspondante de la bande transporteuse (1) sont entourés d'une cabine commune (2). La zone inférieure de chaque poste de triage manuel (4) comporte au moins une sortie d'alimentation en air frais (10), de surface importante, tandis que chaque zone supérieure est équipée d'une sortie d'évacuation (22), intégrée dans une hotte d'évacuation continue, s'étendant parallèlement au-dessus de la bande transporteuse (1).
