Description

Technical Field

[0001] The utility model belongs to the technical field of iron black production devices, in particular to a pulping device used for iron black production. Background Art

[0002] Iron black, also known as iron black pigment, is an iron oxide pigment with the chemical name ferroferric oxide. It has a saturated bluish-black color and a relative density of 4.73. It has high covering power and tinting power, and is very stable to light and atmosphere.

[0003] The production process of iron black pigment involves a pulping process, in which the iron oxide black filter cake needs to be put into a barrel and water is added for pulping, and a slurry of a certain mass concentration is prepared, and then other steps are performed to obtain a suitable iron black pigment. When the pulping device in the prior art is in use, the iron oxide black filter cake is often broken up and mixed with water to form a slurry by the rotation of the stirring paddle on the rotating shaft. However, in actual use, since the pulping object is the iron oxide black filter cake, the filter cake itself is extruded under a certain pressure, so the first thing to do in the pulping process is to break up the iron oxide black filter cake; but the mass of the block filter cake is large, and it is easy to sink to the bottom during the pulping process, and the entire stirring and pulping time needs to be extended to obtain a suitable slurry, which prolongs the pulping time and reduces the efficiency of pulping.

[0004] Therefore, there is an urgent need for a pulping device for iron black production to solve the above technical problems. Utility Model Content
