Description

Two-fluid injection nozzle {TWO-LIQUIDS JETTING NOZZLE}

The present invention relates to a two-fluid spray nozzle that finely sprays a liquid such as a liquid disinfectant or pesticide, and in particular, industrial mass production is possible by simplifying the components of the nozzle, which can significantly reduce manufacturing costs, It relates to a two-fluid jetting nozzle that maximizes jetting efficiency despite the simplification of assembly structure and component parts.

In general, injection nozzles for finely spraying fluid are largely classified into single-fluid injection nozzles and double-fluid injection nozzles.

The former single-fluid injection nozzle directly sprays a relatively high-pressure (20-30 bar) single fluid through a pump and a nozzle,

The latter two-fluid injection nozzle is a full-cone injection type with a relatively narrow injection angle (less than 20°) and injection by the principle of a siphon, that is, relatively low pressure (about 4 to 5 bar). The liquid is sucked (liquid sucked out) by the suction force (siphon) generated by the supplied gas and is sprayed through the orifice (nozzle hole) at the tip of the nozzle to spray with air in the form of mist. - Various types of spray can be obtained depending on the combination of spray set-up, so it is commercialized as a number of technologies in industries such as agriculture, livestock, nozzle system for urban quarantine, painting, and coating work.

Patent Document 1 is disclosed as a prior registration technology of the present applicant in relation to such a two-fluid injection nozzle.

In Patent Document 1, the viscous liquid does not stick around the nozzle tip even in the desired spray pattern and uniform spray of the liquid and the spray of the high-viscosity liquid, and the size of the spray particles can be controlled by finely adjusting the liquid spray amount. A fine spray nozzle is presented.

However, Patent Document 1 has a complex orifice structure for supplying air and liquid, that is, a liquid inlet to a nozzle block, which is a connection of air and liquid supply, an air flow path for patterns, an air flow path for pulverization on the nozzle side, and an air flow path for pulverization on the piston side. As it is necessary to process and manufacture a number of long and thin orifices, such as air passages for grinding connected to, it is difficult to process, resulting in a decrease in productivity as well as an increase in manufacturing cost.

In addition, Patent Document 1 has a disadvantage in that the effect of finely spraying the liquid discharged through the liquid spray hole by compressed air is reduced because the discharge end of the liquid spray hole of the liquid cap and the inclined air hole for the pattern of the air cap are formed on the same horizontal plane. To compensate for this, the air cap has a complex structure that adjusts the amount of liquid spray by the needle tip at the front end by the needle accommodated in the liquid passage, that is, the piston, needle support, and seal at the rear of the nozzle block according to needle assembly. There is a problem in that a plurality of components of the member, spring, needle adjusting member, and closing cap must be assembled and arranged.

Therefore, not only the assembly work is complicated, but also the volume of the entire nozzle increases and the manufacturing cost increases. In addition, the liquid spray amount must be adjusted by unscrewing the finishing cap from the nozzle block, and then adjusting the needle adjusting member to There is a disadvantage that the spray amount setting work is completed only when the gap between the tips is adjusted.
