Drying device for high-content carbon black masterbatch

Abstract

The invention relates to a drying device for high-content carbon black masterbatch. The drying device comprises a water tank, a centrifugal mechanism and a dewatering chamber; the dewatering chamber is mounted at the top of the water tank; an annular separation screen is arranged in the dewatering chamber; a centrifugal cavity is formed in the inner side of the separation screen; a drainage cavity is arranged outside the separation screen and communicated with the water tank; a discharge hole is formed in the top of the dewatering chamber; the centrifugal mechanism is arranged in the centrifugal cavity and comprises a rotating shaft and spiral guide vanes, and the upper end of the rotating shaft is connected with an output shaft of a motor; the spiral guide vanes are wound on the rotating shaft and comprise a lower static spiral guide vane and an upper movable spiral guide vane; the inner side edge of the static spiral guide vane and the central axis of the rotating shaft are fixed by an included angle of a first fixed angle; the movable spiral guide vane is an elastic metal spiral guide vane; and an upper end fixed part of the movable spiral guide vane is fixed to an upper end part of the rotating shaft; and the lower part of the fixed part naturally droops and surrounds the rotating shaft, and is in an upward shrinkage state in a natural drooping state. According to the drying device for the high-content carbon black masterbatch, the drying effect of the carbon black masterbatch after granulation is effectively improved, and the later storage and use quality is improved.

Description

Technical field [0001] The present invention relates to a colorimetary production apparatus, and more particularly to a drying device for high content carbon black masterbatch. Background technique [0002] The granulated granulars for granulation of high content carbon black plasma materials include melting, extrusion, spin cutting, cooling, and drying. Due to the melting of the color master material, after extrusion, it is necessary to cool down, while the granulation is generally required to cool the water cooling to cool the temperature to mold. Therefore, dry carbon black masterbatch is required after the finishing is completed. The existing drying method is done by centrifugal dewatering mechanism, and the centrifugal dewatering mechanism is through the principle of centrifugation, and the moisture in the masterbatch is taken out of the surface of the water filter net, and the carbon black masterbatch is The filamentation net utilizes the distinction to the distal end of th...

Problems solved by technology

The existing drying method is accomplished by a centrifugal dehydration mechanism, and the centrifugal dehydration mechanism uses the principle of centrifugal rotation to throw the water in the masterbatch out of the water filter on the side, and at the same time, put the carbon black masterbatch in the The water filter is sent to the far end of the water filter by centrifugal force for centralized collection. However, in this way, in general, due to the structure of the centrifugal dehydration mechanism, it cannot completely isolate the water vapor that flows in after pelletizing. , even if most of the moisture on the surface of the carbon black masterbatch is dried, there will still be more or less water on the carbon black masterbatch transported to the collection port, and even if the centrifugal dehydration mechanism keeps rotating and centrifuging state, part of the water vapor will still flow with the centrifugal chamber to the collection port of the carbon black master batch, and output together with the carbon black master batch. At this time, the water vapor has a very high probability still attached to the carbon black master batch, thus , It is very unfavorable for the storage of carbon black masterbatches that need to be stored for a long time. Due to the influence of moisture, the processing quality of carbon black masterbatches after long-term storage will be reduced, which will affect the quality of the final product
