Abstract

The invention discloses a continuous totally-enclosed solid-liquid separation system which comprises a preheater, a film evaporator, a continuous vacuum suction filter, a positive displacement pump, a horizontal double-shaft dryer, a double-spiral discharging machine and a stock bin, by arranging the preheater, the film evaporator, the continuous vacuum suction filtration machine, the displacement pump, the horizontal double-shaft drying machine, the double-spiral discharging machine and the stock bin which are communicated in sequence, continuous treatment of materials is achieved, efficiency is improved, solid-liquid separation quality is improved, the materials are primarily treated in the preheater, the film evaporator and the continuous vacuum suction filtration machine, the solid content of the materials is increased, and the solid content of the materials is reduced. And then fine solid-liquid separation is carried out through the horizontal double-shaft drying machine, on one hand, the separation quality can be improved, on the other hand, the cost can be reduced, all the components in the embodiment are communicated through pipelines, the whole solid-liquid separation process of the materials can be kept closed and in a whole-process negative pressure state, the sealing performance is improved, harmful gas and liquid leakage is avoided, and the device is more environmentally friendly and safer.
