Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, a kind of high viscosity fluid atomizer of the present invention is described in detail.
As shown in Figure 1, a kind of high viscosity fluid atomizer of the present invention, it is a kind of key components and parts being widely used in modern industry, the cavity 3 comprised, axially through hole is formed with in described cavity 3, the sidewall of cavity 3 has the oil-in 4 be connected with described through hole, one end of described cavity 3 is provided with the shower nozzle 1 inserted in described through hole, the other end of described cavity 3 is provided with the gas distributor 2 inserted in described through hole, described shower nozzle 1 coordinates for interior male cone (strobilus masculinus) microgap in described through hole with described gas distributor 2, described shower nozzle 1 is axially formed with through spout 5, described gas distributor 2 is axially formed with through gas port 6, the setting that described gas port 6 is connected with described spout 5 in the through hole of described cavity 3.The diameter of the gas port 6 of described gas distributor 2 is greater than the diameter of the spout 5 of described shower nozzle 1.
Described shower nozzle 1 include nozzle rod in the through hole being inserted into cavity 3 11 and be integrally formed in described nozzle rod 11 be positioned at the outside one end of cavity 3 for spacing sprinkler cap 7, described spout 5 is formed in the junction of nozzle rod 11 and sprinkler cap 7, the oil-feed side of described spout 5 and fuel-displaced side are formed to the recessed inner conical surface of spout 5 respectively, are axially formed with the oil duct 8 for inserting described gas distributor 2 be connected with the inner conical surface one of described spout 5 oil-feed side in described nozzle rod 11.Described shower nozzle 1 and described cavity 3 are for being threaded or being formed as one.
Described gas distributor 2 includes the air-guide rod 9 that can be inserted into successively in the through hole of cavity 3 and the oil duct 8 of shower nozzle 1, be integrally formed in the limited cap 10 that described air-guide rod 9 is positioned at the outside one end of cavity 3, the other end of described air-guide rod 9 is outwardly male cone (strobilus masculinus) termination, described male cone (strobilus masculinus) termination is embedded in the inner conical surface of shower nozzle 1, and be that microgap coordinates with the inner conical surface of described shower nozzle 1, the angle of inclination of the inner conical surface of shower nozzle 1 described here is greater than the angle of inclination of the male cone (strobilus masculinus) termination of gas distributor 2.Described gas distributor 2 and described cavity 3 are for being threaded or being formed as one.The spout of described shower nozzle 1 can be designed to different shapes, to adapt to different needs.
A kind of high viscosity fluid atomizer of the present invention, whole shower nozzle is divided into two spaces in inside, the heavy pressure gas chamber be made up of oil duct 8, and by spout 5 be positioned at the fluid cavity that its oil-feed side and fuel-displaced side inner conical surface form.By controlling the microgap size between shower nozzle inner conical surface and the male cone (strobilus masculinus) termination of gas distributor, just can reach the size that adjustment spout 5 goes out oil pressure, that is, regulating the size of microgap, the atomizing fluids of different quality and flow can be obtained.Wherein, the microgap formed between gas distributor and shower nozzle adjusts by the screw thread between gas distributor and cavity 3 or the screw thread between shower nozzle 1 cavity 3.Operationally, high viscosity fluid is forced to by the microgap between gas distributor and shower nozzle under pressure, forms the very thin fluid film of one deck at the inner conical surface of shower nozzle.
The air passed in gas distributor 2 gas port 6 is compressed air, and gas pressure is generally 1 to 10Bar.Gases at high pressure arrive the inner conical surface of shower nozzle by gas port 6, and again due to the drag effect of inner conical surface, gas forms strong turbulent flow at this.Sweep away the high viscosity fluid on inner conical surface and fully mixing simultaneously.Gas carries the spout 5 that high viscosity fluid proceeds to shower nozzle further, and because the diameter of spout 5 is less, gas is accelerated at this, and heavier fluid is shredded into more small particle further simultaneously.When this gas-liquid mixture have passed spout 5, then enter diffuser, and spouting according to diffuser shape.Define the high viscosity fluid of atomization.
In use, in order to obtain stable spray pattern, need in the front end of nozzle to introduce high viscosity fluid stable-pressure device, and gases at high pressure stable-pressure device.
In the assembling process of vehicle dormer window, in order to reduce frictional resistance need to moving component, mechanical group, guide rail sunshading board etc. carries out oiling operation.Have employed high viscosity fluid atomizer of the present invention in this example coordinates robot to realize oiling operation, and its beneficial effect is, is coated with pasta and oil evenly, do not need artificial secondary hairbrush to distribute.And at grease constant pressure, under the prerequisite that the existing movement velocity of robot is constant, can, by the microgap of Control Nozzle and gas distributor, control to be coated with oil mass.
