Full-process automatic solid-liquid separation and drying system for dye intermediate

Abstract

The invention provides a full-process automatic solid-liquid separation and drying system for a dye intermediate. The full-process automatic solid-liquid separation and drying system comprises a full-automatic discharging centrifugal machine, an automatic material conveyor, a rotary flash drying device, a dust removal collector and an induced draft fan, wherein the full-automatic discharging centrifugal machine automatically feeds water-carrying material, and centrifuges and filters the water-carrying material into a filter cake; the automatic material conveyor conveys the filter cake to the rotary flash drying device to further finely smash, suspend and thermally dry the filter cake into dry powders by virtue of dry hot air; then the dry powders enter the dust removal collector and are collected in the dust removal collector in a dust removal mode; and waste gas is extracted by the induced draft fan and sent to a tail gas treatment system. According to the full-process automatic solid-liquid separation and drying system, the functions of automatic centrifugal dehydration, filtration, automatic feeding, automatic flash drying, automatic collection and the like of the water-carryingmaterial can be realized, so that the labor cost and the material loss are saved, the treatment efficiency of the water-containing dye intermediate is improved, and the process cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of dye process equipment, and in particular relates to a solid-liquid separation and drying system for dye intermediates that is fully automated. Background technique [0002] There are many equipments on the market for the separation, washing and drying of dye intermediates. Filtration and washing equipment includes suction filter tanks, filter presses, pressure filters, centrifuges and other equipment. Drying equipment includes various ovens and dryers. . However, most of the existing varieties have the following defects: (1) The processes of filtration, washing, dehydration, and drying are carried out separately, which is inconvenient to operate, and most of them need to be opened and used in conjunction with multiple devices, and manual processing is required. Low, long production time, more manual use, and the labor intensity of the workers is high, and the working environment of the workers is poor; (...

AI Technical Summary

Problems solved by technology

[0003] There is no automatic control in the above-mentioned whole process, and the connection between equipment and equipment is completed by manpower. There are many equipment and transfer pallets used for materials, which occupy a large space in the workshop, and it is necessary to set up a pallet parking position; the production capacity of each shift is small, and the output cannot be increased; The tail gas generated in the whole process is difficult to collect and cannot meet the current environmental protection requirements
