A device for preparing mixtures, for example, for dissolving dyes in powder form, and the like, in textile plants

摘要

The device comprises a tank (2) which can receive buckets (S) in which there is a product such as a pigment to be mixed with a vector, such as a liquid, which is supplied to the lower portion of the tank (2). At least one rotary turret (100) associated with the tank (2) has an arm (104) on the free end of which there is a plate (61) on which the buckets (S) are deposited. As a result of a rotary movement about its axis (X100) followed by a lowering movement, the turret (100) brings the bucket (S) to a central position inside the tank (2) which is closed at the top by a lid (3) which can move vertically upwards and downwards. The rotation of the arm (104) of the turret with consequent inversion of the bucket (S) causes the pigment to fall into the tank in the bottom of which there is a mixer (67) which brings about intimate and complete mixing of the product poured into the vector. The mixture thus obtained can be transferred automatically and selectively towards user stations (V1, V2, V3) by pumping means (7) acting in the bottom region of the tank (2). Means are provided for automatically washing the tank and the bucket (S) upon completion of the mixing operations. The preferred application is in the dye-houses of textile plants. <IMAGE>
