Utility model content
For above the deficiencies in the prior art, technical problem to be solved in the utility model is to provide a kind of spray gun, is intended to solve the problem such as the microballon roundness prepared in existing lance driving device is poor.
For above-mentioned the deficiencies in the prior art, the utility model proposes a kind of spray gun device, comprising:
One mixing chamber, has upper chamber, middle chamber and lower chambers three parts;
One output channel, inner chamber is cylinder shape;
At least in mixing chamber, upper chamber arranges a feedstock pipeline, combustion-supporting gas intake ducting, and be provided with negative pressure device in feedstock pipeline ingress, the ingress of combustion-supporting gas induction trunk is provided with air compressor I; Middle chamber is provided with gas inlet pipeline, and is provided with air compressor II in the ingress of gas inlet pipeline; Lower chambers is a unsealed rectangular cavities;
Nozzle is provided with foremost at output channel.
Further, for reducing the resistance of fuel gas flow in pipeline, the center of described gas inlet passage and the center of described output channel are on same level line, thus reduce the collision of flowing combustion gas and tube wall.
Further, for reducing powder and the combustion-supporting gas resistance at Bottomhole pressure, the angle of described output channel and described mixing chamber inwall is 35 ~ 50 °.
Further, for ensureing there is sufficient raw material in pipeline, described output channel can be provided with the second feedstock pipeline.
Further, in order to ensure that raw material and combustion gas, combustion-supporting gas maintain higher speed after spray gun, and match with the speed of Cheng Zhulu Cheng Zhu, the internal diameter of described feedstock pipeline inner chamber is 20 ~ 30mm, the internal diameter of described combustion-supporting gas induction trunk inner chamber is 3 ~ 20mm, the internal diameter of the inner chamber of described gas inlet passage is 3 ~ 20mm, and the internal diameter of described output channel is 15 ~ 25mm, and length is 20 ~ 30cm.
Further, for ensureing at described material inlet place, the continual supply in the second material inlet place, be provided with the feed chute used that to match with it.
The beneficial effects of the utility model are: spray gun provided by the utility model, fully combustion-supporting gas, combustion gas can be mixed with base glass powder, thus drive glass powder to produce certain speed and spray in roasting kiln, requirement to temperature, length and speed during to meet glass powder balling-up, makes the roundness of the high-refraction glass bead produced better; Meanwhile, the spray gun for the preparation of high-refraction glass bead provided by the utility model, its throughput is 80 ~ 200 kilograms/h, far away higher than existing apparatus, substantially increases production efficiency, shortens the production time; Finally, this apparatus structure is simple, easy to operate and with low cost, is easy to promote.
