The invention relates to a heating device for organic pigment production. The heating device comprises a heating pot which is positioned above a support frame body; a hot fluid heating component which stretches into the heating pot is detachably connected to an upper end opening of the heating pot; a stirring mechanism is arranged at the bottom of the heating pot; the hot fluid heating component comprises a cover body capable of being detachably connected to the upper end opening of the heating pot; the lower part of the cover body is provided with a coil pipe support; a heating coil pipe in which hot fluid can pass is intertwined on the coil pipe support; and the cover body is provided with a hot fluid inlet and a hot fluid outlet which are communicated with the heating coil pipe. The heating device has the beneficial effects that the stirring mechanism is arranged at the bottom of the heating pot; the top space of the pot body is large; material feeding is convenient; and the stirring mechanism is convenient to examine and repair as well; the hot fluid heating component is detachably connected to the top of the heating pot, and is convenient to examine, repair and replace; the cover body of the component can effectively prevent liquid in the pot from being spilled out during stirring; and meanwhile, the heating efficiency can be improved or lowered by changing the structure of the coil pipe support of the component.
