The first step installs carbon-point 4 additional.When installing carbon-point 4 additional, accommodation space 12 is filled it up with the carbon-point 4 that perhaps installs some amount additional according to the requirement of output.Open the loam cake 11 of installation device 1; From installing mouthful the accommodation space 12 of many carbon-points 4 being put into installation device 1 additional, loam cake 11 is closed after installing completion additional, after installing additional; Because the effect of gravity; Always have a carbon-point 4 can drop in the said long column shape groove, and said long column shape groove can only a ccontaining carbon-point 4, shown in carbon-point 4 in the installation device 1 can free fall one by one in the long column shape groove of installation device 1 bottom.
Second step carried carbon-point 4 to activator 2.When the valve 51 of passage 5 was opened, the push rod 13 on the long column shape groove left side will be transported to the carbon-point in the long column shape groove 4 top of activator 2 to the right through valve 51, and push rod 13 is moved to the left and gets back to starting position then, and activator 2 imported valves 51 are closed.Because the diameter of push rod 13 is identical with the diameter of carbon-point 4; Therefore; Push in the process of carbon-points 4 at push rod 13, all the other carbon-points can't fall in the long column shape groove, and push rod 13 be moved to the left again get back to starting position after; Just have in the installation device 1 in the long column shape groove that a carbon-point 4 drops on the bottom, wait for that carbon-point 4 next time carries.
The carbon-point activation of the 3rd step.With the logical hundreds of amperes of direct currents of electrode 21,22, and by electric motor driving electrode 21,22 vertically relatively near with relatively away from.When activator 2 was prepared carbon-point 4 activation, electrode 21,22 was relatively near the length of the left and right end spacing that arrives supporting part less than carbon-point 4, when carbon-point 4 falls from activator 2 tops; Just in time accepted by the supporting part of electrode 21,22, two said supporting parts respectively support an end of carbon-point 4, and electrode 21,22 begins logical direct current activation carbon-point 4 then; After 4 activation are accomplished through the certain hour carbon-point; Electrode 21,22 outage, electrode 21,22 moves withdrawal to both sides respectively, make between them between from length greater than carbon-point 4; Carbon-point 4 is freely fallen in the long column shape groove of activator 2 bottoms; Preparation is transported in the synthetic furnace 3 by push rod 24, and electrode 21,22 is got back to the state of preparing activation carbon-point 4 again, and promptly the spacing between them is less than the length of carbon-point 4.
The 4th step carried carbon-point 4 to synthetic furnace 3.Carbon-point 4 activation drop in the long column shape groove of activator 2 bottoms after accomplishing; When activator 2 outlet valves 61 on the right are opened; The push rod 24 on the left side will be transported to the carbon-point in the long column shape groove 4 in the synthetic furnace 3 through valve 61 to the right, and the front portion of push rod 24 can be inserted in the synthetic furnace 3; Until be pushed to carbon-point 4 in the anode pipe 31 and carbon-point 4 when having 4/5ths to stretch out anode pipe 31 till; Push rod 24 is moved to the left and gets back to starting position then, prepares to carry next time, and valve 61 is closed.At this moment activator 2 has been ready to next root carbon-point 4 is carried out activation.
The carbon-point discharge of the 5th step is synthetic.When the carbon-point after the activation 4 was transported in the synthetic furnace 3 by push rod 24 through synthetic furnace 3 anode pipe 31, carbon-point 4 had 1/5th in anode pipe 31, all the other 4th/5th, be suspended in the synthetic furnace 3 as anode.Activator outlet valve 61 is closed at this moment, and synthetic furnace 3 can discharge.At this moment; The carbon-point 4 that stretches out in anode pipe 31 directly adds tens volts of volts DSs with negative electrode 32, and negative electrode 32 moves to the direction as anodic carbon-point 4, when negative electrode 32 touches carbon-point 4; Electric current forms the loop; Negative electrode 32 spaces out gradually with as anodic carbon-point 4 again, between the two poles of the earth, just forms electrical discharge arc, and discharge is synthetic formally to be begun.Progressively be consumed in the discharge building-up process as anodic carbon-point 4, continuous in order to keep the two poles of the earth distance necessarily to reach electrical discharge arc, negative electrode progressively is moved to the left along with carbon-point 4 shortens, and when electrical discharge arc will burn the mouth of pipe of anode pipe 31, discharge stopped.Negative electrode moves right and gets back to starting position, and activator 2 outlet valves 61 are opened and had a process activatory carbon-point 4 from anode pipe 31, to be transported in the synthetic furnace 3 simultaneously, and discharge is synthetic can to have been begun again.
Five above-mentioned steps can be carried out simultaneously, and when synthetic furnace 3 discharge was synthetic, activator 2 can activation carbon-point 4, and when activator 2 activation carbon-points 4, installation device 1 can be opened and install carbon-point 4 additional.Make and install carbon-point, activation carbon-point additional, discharge synthesize nano carbon material has been realized the flow line production technique.
To sum up, carbon nanomaterial synthesizer of the present invention and carbon nanomaterial compound method, when having solved prior art arc process synthesize nano carbon material, the problem that carbon-point activation and carbon-point discharge can not be carried out simultaneously; Realized to open synthetic furnace and need not stop arc-over, just can install carbon-point and activation carbon-point additional, made production efficiency be more than doubled, and realized with industrially scalable synthesize nano carbon material than original device.
