As a kind of improvement, described feeding device is arranged on the described negative-pressure pipeline, and described feeding device comprises reinforced valve and the reinforced hopper that is installed on the described reinforced valve.
Owing to adopted technique scheme, the beneficial effects of the utility model are: because shaping device is provided with airflow milling and is connected by the material circulation canal with grader, make silicon carbide micro-powder in the shaping process, can circulate continuously, the tiny flour that shaping obtains can be collected outward by the air inducing air-flow machine that is discharged to of grader, being sent back in the shaping mill by conveying device that the shaping micro mist is not qualified continues shaping, the product that shaping obtains is collected in material collecting barrel, has improved production efficiency.
Owing to be provided with up big and down small conically shaped in the material collecting barrel, disperse after making material enter material collecting barrel, those micro mists that have only negative pressure to draw can be by the osculum of conically shaped, and just the particle diameter of the micro mist that grader separated is littler, has improved the grader precision.The shaping scope of shaping device also further obtains expanding simultaneously, not only can put in order the big silicon-carbide particle of particle diameter, also can put in order the little silicon-carbide particle of particle diameter, small particle diameter carborundum can not be pulverized in airflow milling once more, just by phase mutual friction between the silicon carbide micro-powder, thereby become mellow and full, do not have corner angle, play the effect of shaping.
Feeding device can be arranged on the optional position of material circulation canal, handled easily, and reinforced valve is closed after reinforced, makes shaping device keep sealing in the course of the work.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: 1, gas flow sizing machine, 2, material collecting barrel, 3, conically shaped, 4, sample cock, 5, screw conveying device, 6, product outlet, 7, feed pipe, 8, nozzle, 9, grinding cylinder, 10, reinforced valve, 11, reinforced hopper, 12, blocking material ring.
The specific embodiment
As shown in drawings, a kind of internal-circulation type silicon carbide micro-powder shaping device comprises airflow milling, and described airflow milling comprises grinding cylinder 9, and described grinding cylinder 9 is provided with at least one pair of nozzle that is communicated with source of the gas 8; Material collecting barrel 2, described material collecting barrel 2 bottoms are provided with conveying device, described conveying device is connected with described airflow milling, described material collecting barrel 2 tops are fixedly connected with gas flow sizing machine 1, be provided with negative-pressure pipeline between described material collecting barrel 2 and the grinding cylinder 9, by described conveying device and negative-pressure pipeline, form the material circulation canal between described material collecting barrel 2 and the grinding cylinder 9; Feeding device, described feeding device are arranged on the described material circulation canal.
Be provided with a up big and down small conically shaped 3 in the described material collecting barrel 2, described conically shaped 3 is fixedly installed in the inwall of described material collecting barrel 2 and is positioned at the below of described gas flow sizing machine 1.Be provided with blocking material ring 12 in the described material collecting barrel 2, described blocking material ring 12 is fixedly installed in the top of described material collecting barrel 2 and around the grading wheel end of described gas flow sizing machine 1, prevents that micro mist from discharging by the gap between grading wheel and material collecting barrel 2 top end cover.
