Metering bunker for particulate materials partic. of lignocellulose

摘要

Bulk particles of organic and/or inorganic origin, partic. lignocellulose and/or cellulose-contg. particles mixed with binders for mfr. of chipboard etc. are metered from a bunker comprising a housing with vertical side walls and longitudinal walls (4) and a base formed by an endless belt (7) passing around two deflection rollers (8). At least the lower wall regions of the longitudinal walls facing the belt each consist of a side (24) of an endless belt (20) circulating synchronously at the same speed as the base belt. Pref. the endless belts are sealed w.r.t. the base belt by seals (23) applied to the belt outside the bunker. Pref. the endless belts consist of a transparent material, rubber, plastic e.g. polypropylene, Teflon or similar such that rubber or plastic can be reinforced.
