Abstract

Improvements in the patent of invention no. 425.022 for improvements in the apparatuses for treating wet fabrics, of the type in which the fabric is arranged in endless rope and circulates in a closed enclosure, dragged by a feed turnstile and the treatment liquid itself, determining a fast one-way circuit and a slow return circuit in which most of the fabric is accumulated for its treatment, in which the closed enclosure, suitable for working with or without pressure, comprises in combination the following parts: A) an elongated tubular central body, acting as a storage chamber for the treatment liquid and for the tissue to be treated. B) an end tubular body, attached to the entrance of the central body, with an entry base smaller than the exit one, which gives access to the storage chamber. C) an upwardly angled body, attached to the central body, which forms part of the storage chamber. D) a transition body, with a greater section at the exit than at the entrance, joined to the bent body. E) an upper body joined to the transition body, which has a greater section than the central body, equipped with a cover for loading and unloading, and houses the upper part of a transport conduit. F) a transport conduit that connects the upper body, where it has an axial embouchure, with the aforesaid extreme end body, to complete the closed circuit of the enclosure in its fast circuit phase, and runs under the storage chamber. G) activation means consisting of a turnbuckle contained in the transition body and/or higher, driven by a drive motor group, on whose periphery the tissue is supported for delivery to the lateral mouth of the transport conduit, which ends, inside the upper body, in an axial embouchure that defines an overflow chamber that contributes to the dragging of the tissue by means of the treatment liquid when it is poured into the transport conduit and impinges against the tissue in the lateral embouchure, in eventual collaboration of a injection chamber located around the conduit below said lateral embouchure. H) a circulation pump having its suction tube communicated with one or several points of the storage chamber, to extract liquid from it, while its delivery tube, passing through a heat exchanger, communicates separately with the overflow and injection chambers, said tubes and their branches having valves for adjusting the flow of liquid to control the displacement of the liquid and tissue by the device, characterized in that the transport conduit connects the upper body with the extreme tubular body, completing the circuit of the enclosed space, is located below the storage chamber, while the activation means consist of a horizontal turnstile driven by a speed variator motor group, on whose periphery the fabric is supported for its delivery to an upper embouchure of the transport conduit that penetrates the upper body, this being contained mbocadura in an overflow chamber for dragging the fabric by means of the treatment liquid to pour into that mouth, in possible collaboration with an injection chamber located around the transport conduit, in a lower level of the overflow chamber projecting liquid in the transport conduit.
