Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of pigment production, more particularly, it relates to a raw material dropping mechanism for pigment production. BACKGROUND

[0002] When azo pigment is produced, diazotized liquid needs to be added into the coupling barrel containing coupling liquid so as to fully carry out coupling reaction. The diazotized liquid is loaded in a diazotized liquid tank, and the diazotized liquid tank is provided with a liquid inlet valve, a liquid outlet valve, a vent valve and a pressure valve, so as to facilitate the injection of diazotized liquid into the diazotized liquid tank or the discharge of diazotized liquid from the diazotized liquid tank. However, the current raw material dropping mechanism generally directly places the diazotized liquid tank above the coupling barrel, manually opens the liquid outlet valve on the diazotized liquid tank, and discharges the diazotized liquid in the diazotized liquid tank. However, when the diazotized liquid is added, the liquid outlet valve is easily opened too large, which causes the diazotized liquid to be quickly injected into the coupling liquid, and it is difficult to control the adding amount and the adding speed. In addition, some coupling barrels are provided with a cover plate, a driving motor is installed on the cover plate, stirring blades are provided below the cover plate, and the stirring blades are driven to rotate by the driving motor during the adding of diazotized liquid, so as to stir the coupling liquid and the added diazotized liquid, so that they are fully mixed, and the coupling reaction is fully carried out. At this time, the diazotized liquid tank is installed on the cover plate. When the stirring blades need to be cleaned, the diazotized liquid tank needs to be removed together. The weight of the diazotized liquid tank is large, and it is time-consuming and laborious to remove the diazotized liquid tank. In addition, the diazotized liquid tank needs to be kept stable and cannot be inclined during the removal process, and the safety risk is high. CONTENT OF THE UTILITY MODEL
