Single-air traveling suction blower claener with automatic doffing

摘要

57 A traveling suction floor cleaner (20) for cleaning textile mills and adapted for periodic removal of textile waste material collected by the cleaner, comprises a suction blower fan enclosed in a housing (26). Suction ducts (22) communicate with the housing (26) and are arranged for carrying suction air and entrained textile waste material from the floor of a textile mill to the suction blower fan. The fan, housing (26) and ducts (22) define suction air paths within each of which is positioned a cylindrical tubular filter (27) having arcuate filtration surfaces (30a, 30b. 30c) positioned within the respective suction air path for receiving entrained textile waste material while permitting air flow therethrough. A motor (31) is operable to rotate each filter (27) so as successively to present clean filtration surfaces (30a, 30b, 30c) to the suction air path to collect textile waste therefrom, and to concurrently successively upwardly present the filtration surface means having collected textile waste material thereon to a system (43-Figure 1) for removing the collected waste material from the filtration surfaces, when the cleaner (20) moves beneath the removal system (43).
