Carbon black grinding device for single-component polyurethane preparation

Abstract

The invention discloses a carbon black grinding device for single-component polyurethane preparation. The device comprises a stirring box, wherein a charging device is mounted on the side surface of the stirring box; a discharging bin communicates with the top part of the stirring box, and the side surface of the top part of the stirring box communicates with a soaking solvent adding device; and ametering device is mounted on the soaking solvent adding device. According to the carbon black grinding device for the single-component polyurethane preparation, the charging work can be performed through the charging device, and the charging device is high in mechanical degree, so that the problem of manual charging is avoided, and both time and force can be saved; the adding quantity of soakingsolvents can be metered through the metering device, and the metering device is high in metering accuracy, so that the mixing accuracy of the soaking solvent and a carbon black is greatly improved, and the carbon black can be dispersed conveniently, and as a result, the following grinding work can be smoothly carried out; materials residual on the inner wall of a grinding box are cleaned througha cleaning device, and the cleaning device is convenient to clean, and the problem of manual cleaning is avoided, and moreover, the raw material waste is decreased.
