Second fluid nozzle

Technical field

The utility model is about a kind of second fluid nozzle, be in particular a kind of by interstructural matching design, to reach energy-saving effect and can spray the second fluid nozzle that disengages the splendid gas-liquid mixture fluid of the ability of cleaning.

Background technology

In the industrial products manufacture process, there are many processing procedures when carrying out, can produce many chips or little bits usually, and then the surface of polluting institute's converted products, therefore also need be in the production line down-stream, wash processing, for example: the processing procedure of electronic industry printed circuit board (PCB) (PCB), the wet process of printed circuit board (PCB) (PCB), at circuit board plate face after grinding, must be with sand-blasting machine with the uniform roughening treatment of smooth surface, make the etch resistance layer easily attached on the plate face, removing in the sand-blasting machine has sand water external demand that sandblast nozzle ejection alligatoring uses through the multiple tracks water-washing process, with bored on plate face and the plate on the appropriate pore residual diamond dust clean; It is by a fluid nozzle that passing flushing is handled, utilize water that the high-power pumping will be a large amount of to pressurize after, come the surface of washing processing product through nozzle; Yet, the suitable consumption of water resource of this kind cleaning way, as: use the industry of a fluid cleaning equipment on the market, washing bay, pig farm etc. all are the pumpings of utilization high-power, with the direct pressure flush of water, the water yield that expends relatively is also quite a lot of, and these a large amount of water users, and obtaining often of water source supplied with groundwater abstraction, so for years, will cause the exhausted harm that also easily causes environment of groundwater resources.

And it is thicker via the globule particle that nozzle sprayed, therefore can't remove little bits and residual sand in the pore, the little bits and the residual sand that adhere to can't be cleaned, the ultrasonic machine that then need be dependent on down-stream cleans, though the ultrasonic machine can reach clean effect, but, shake the residual sand of the Buddha's warrior attendant that gets off, can cause damage for the ultrasonic machine; Therefore, can cooperate an air pressure that the globule particle of ejection is fair with water atomization, like this then wash away clean effect can increase flushing the time, and can use high-pressure water mist to remove to be attached to little bits of pore hole wall, this kind sprays the water smoke mode and is two fluid sprays.

The existing on the market at present employed nozzle of two fluid sprays, according to its gas and liquid hybrid mode, be broadly divided into two kinds of outer mixing and interior mixing, the gas of outer mixed atomizing and liquid are earlier after mixing is finished in spray group mouth outside, enter the nozzle ejection again, the gas liquid mixing portion of interior mixed atomizing designs in nozzle, and this form is second fluid nozzle.And second fluid nozzle according to the difference of its pressuring method, must be divided into hydrocone type and double voltage type; The liquid of hydrocone type second fluid nozzle can't pressurize before entering mixing portion, and the liquids and gases of double voltage type second fluid nozzle then must pressurize; And the hydrocone type nozzle is to utilize siphon principle, produces pressure differential with compressed air in nozzle mixing portion, and liquid is sucked mixing portion mixes with gas, fluid-mixing is sprayed simultaneously again.

Yet, the processing of jet parts, in accessory size, collimation or concentricity etc., in the process of making, the difficult generation of avoiding error, the error amount that is produced when these occur in part processing is when nozzle uses, the gas-liquid mixture fluid that spray disengages produces the situation of deflection, causes unstable and uneven situation; And the part of nozzle, if directly offer a spout in the shower nozzle front end, and there is not the design of water conservancy diversion, then easily produce turbulent flow in the shower nozzle front inner wall, if turbulent flow backwashes, then will form resistance, what is more to gas-liquid mixture fluid, power is crossed and then may be allowed gas refunds liquid line by force if backwash, and causes siphonage to disappear.

Therefore the designs of nozzles of present two fluids is all washed away towards increase and is cleaned stable that effect and spray disengage, and also reduces expending of gas, liquid and improves simultaneously.

This shows that above-mentioned existing mode still has many disappearances, real non-one kindhearted design, and demand urgently being improved; Every shortcoming that this case creator derives in view of above-mentioned existing mode is urgently to think to be improved innovation, and after concentrating on studies through taking great pains to attain one's goal for many years, successfully second fluid nozzle of the present utility model is finished in research and development finally.
