<p>1,215,071. Travelling-band filters. VALMARCO SOC. ANON INDUSTRIAL Y COMERCIAL. 15 Feb., 1968 [24 July, 1967; 27 Oct., 1967], No. 7438/68. Heading BID. Liquid containing solid detritus 5 e.g. bottle labels is introduced at 6 into a housing 1 and flows through a perforated travelling band 10, the detritus 5 being trapped in the space 22 between band 10 and a second band 19, conveyed upwardly and discharged at 12. Rollers 11, 20 are driven, and the bands are substantially as wide as the housing 1. As described liquid free from labels exits through a duct 17 and is returned via a duct 25 by a pump (23), Fig. 2 (not shown). Bands 10, 19 comprise a series of articulated plates, band 10 being perforated. Rollers 11, 20 are driven through gearing by a common motor (Fig. 2) such that band 10 travels slightly faster than band 19. The rollers and bands may be removed for cleaning.</p> |
