Description of drawings
Accompanying drawing is the utility model structural representation
Embodiment
Accompanying drawings further describes as follows to the utility model.
Be used to produce the splitter of metal carbonyl powder, it is characterized in that this splitter comprises: the upright cylinder of cylindrical shell 2-make for stainless steel, the upper end of cylindrical shell is provided with joint flange, and the bottom of cylindrical shell is provided with the taper of band joint flange and closes up, and the L/D ratio of cylindrical shell is 8: 1; Cover plate 8-be positioned at the top of cylindrical shell, this cover plate is provided with the stainless steel ring flat-plate of nitrogen inlet and pressure tap 7,12, is connected by the joint flange of bolt with the cylindrical shell upper end; Heat tape 3-be trapped among outside the cylindrical shell sets up 6 heat tapes from top to bottom separately; Lower support frame 11-be fixed in the outside, cylindrical shell bottom funneling, its upper end is provided with joint flange; Nitrogen protection chuck 1-support and be fixed on the lower support frame, the cylinder that by steel plate be welded of chuck on cylindrical shell and heat tape, to be welded with internal diameter identical with the cylindrical shell external diameter with this chuck and cylindrical shell respectively between each heat tape in the nitrogen protection chuck, the doughnut-shaped steel plate 13 that external diameter is identical with nitrogen protection chuck internal diameter, doughnut-shaped steel plate and the cylindrical shell identical with the cylindrical shell external diameter at the internal diameter of nitrogen protection chuck topmost weld mutually, and on its circumference, being provided with joint flange, the position of each heat tape is respectively equipped with power interface 10 on the nitrogen protection chuck; Upper support frame 9-be fixed in the cylindrical shell upper outside, its underpart circumference is provided with joint flange, and the joint flange Joint by bolt and nitrogen protection chuck topmost; Blanking base cone 4-be the conical shell by stainless steel weldering system with angle, its top is provided with air outlet 5 and joint flange, and is connected by the joint flange of bolt with the cylindrical shell bottom, and its underpart is provided with thief hole 6 and joint flange.
When using the utility model, load onto special stainless steel nozzle at its cover plate feeding mouth, upper level tempering tank nickle carbonoxide and iron carbonyl and CO mixed gas enter splitter by nozzle.
Regulate 300 ℃-400 ℃ of each heat tape temperature of splitter.Nickle carbonoxide and carbonyl iron steam are tiny crystal seed once entering the splitter decomposes, these crystal seeds slowly descend in splitter, along with the continuation of nickle carbonoxide and iron carbonyl gas is decomposed, crystal seed is grown up gradually, falls into nickel powder and iron powder intermediate bin that the splitter bottom is connected with the joint flange of blanking base cone bottom by joint flange at last.CO gas after the decomposition flows through heavy ash tube through the air outlet, dust-precipitator is taken away by recirculation blower.For avoiding the air admission splitter, the Control Circulation rotation speed of fan makes and keeps minute-pressure power in the splitter.Logical nitrogen in the nitrogen protection chuck of splitter, in case cylindrical shell leaks, the nitrogen in the nitrogen protection chuck can enter in the splitter and CO in the splitter or nickle carbonoxide and iron carbonyl gas can not enter the workshop.
