<p>1,143,304. Textile treating apparatus. VEPA A. G. 30 Jan., 1967 [29 Jan., 1966], No. 4431/67. Heading D1L. Apparatus for wetting textile material 19 comprises a container 1 for liquid, a sieve drum 7 rotatably mounted in the container so as to be partially immersed in the liquid, means for conveying the material 19 to the immersed part of the drum 7 at least one partition 9 within the drum dividing it into a pressure chamber 11 and a suction chamber 10, and at least one pump 13 located inside the drum for circulating liquid from the container 1, through the material 19 into the suction chamber 10, thence to the pressure chamber 11 and back to the container. There may be more than one pump 13 situated within the drum and driven, for example by V-belts from a motor 18 located outside the drum. The partition is preferably arranged parallel with the axis of the drum and may be adjustable in position e.g. swung angularly with respect to the drum axis and sealed against the rotating part of the drum. The drum surface may be covered with a coarse wire mesh which in turn can carry a relatively fine wire mesh. The end faces of the drum comprise bearing rings 8 of U cross-section engaging rollers mounted on a fixed part of the respective end faces supported at 33. The inner surface of one end face bearing ring 8 has a toothed formation for engagement with a pinion driven from a suitable motor for rotation of the drum (Fig. 4, not shown). The whole sieve drum unit may be suspended from a cross bar 34 connected with the end faces of the drum and may be lifted in and out of the container as a unit. After treatment on the drum the material passes between squeeze rollers 20 and may then be fed to subsequent wet treating apparatus. The liquid squeezed out by rollers 20 is collected in a tank 23 having a fixed sieve 24 and divided into a first and second zone with an adjustable orifice therebetween (Fig. 2, not shown). With a series of treatment apparatus the tanks 23 may be interconnected so that liquid can flow from the first zone of one tank to the second zone of the preceding tank via pipe 32 and in addition liquid from the second zone of each tank can be pumped by pump 19 via pipe 30 back into the container associated therewith. A part of the liquid sucked into the drum may be passed out via channels 14a through the uncovered part of the drum so that the drum is constantly cleaned.</p> |
