Abstract

The invention relates to a nozzle of an atomizer, the nozzle comprises a nozzle body, a medium through hole is arranged on the nozzle body, and a jet orifice of the medium through hole is shaped like three to six pedals of plum blossom. The nozzle has simple structure and low manufacturing cost; the energy loss of jet gas is less, the atomization breakup effect is better, fine products after the atomization breakup by the nozzle are more than the products by the prior flat nozzle by more than 20 percent; the nozzle is difficult to have the blockage phenomenon, and the work is reliable.

Description

A kind of atomizer nozzle

Background technology

The existing atomizer nozzle jet end face of making ultrafine metal powders end usefulness mostly is plane (being commonly referred to " flat mouth "), and spray regime is the flat fire formula, and spray angle is little, the energy loss of gas jet is big, the atomizing crushing effect is relatively poor, and fine product is few, and choking phenomenon takes place easily.

Summary of the invention

The objective of the invention is to overcome the above-mentioned defective that existing atomizer nozzle exists, provide a kind of energy loss of gas jet little, the atomizing crushing effect is good, and fine product is many, and is difficult for the atomizer nozzle of obstruction.

The objective of the invention is to be achieved through the following technical solutions:

It comprises nozzle body, and nozzle body is provided with medium through hole, and the jet of medium through hole is shaped as three to six plum blossoms petal-shaped (can be described as " plum blossom mouth ").

The preferred version of described jet shape is that four plum blossoms are petal-shaped.

Plum blossom mouth of the present invention with the situation of the existing equal injection flow of flat mouth under, prolonged jet peripheral profile line, increased the jet sectional area, make distribute from the liquid medium of jet ejection wideer, thereby provide more advantageous conditions for liquid medium atomizing fragmentation; Moreover plum blossom mouth of the present invention sprays fracture area (collision, tear zone) and sprays the broken head of district than existing flat mouth, like this, reduce all the converge loss of collision energy of flat mouth jet air-flow, strengthened the atomizing crushing effect, and, the broken good stability that atomizes, jet are difficult for blocking.

The present invention is simple in structure, low cost of manufacture; The energy loss of gas jet is little, and the atomizing crushing effect is better, and the fine product of nozzle atomization fragmentation is Duoed more than 20% than existing flat mouth; Be difficult for taking place choking phenomenon, reliable operation.

Description of drawings

Fig. 1 is the front view of existing atomizer nozzle (flat mouth);

Fig. 2 is the front view of one embodiment of the invention;

The specific embodiment

The present invention is further illustrated below in conjunction with drawings and Examples.

With reference to Fig. 2, present embodiment comprises the nozzle body 2 that is processed into by jade, and nozzle body 2 is provided with medium through hole 1, and the jet 3 of medium through hole 1 is that four plum blossoms are petal-shaped.

Facts have proved that through several years the fine product of present embodiment nozzle atomization fragmentation has Duoed 25% than existing flat mouth, has promptly brought up to 55% by 30% of flat mouth.

Claims (2)

1, a kind of atomizer nozzle comprises nozzle body, and described nozzle body is provided with medium through hole, it is characterized in that, it is petal-shaped that the jet of medium through hole is shaped as three to six plum blossoms.

2, atomizer nozzle according to claim 1 is characterized in that, it is petal-shaped that described jet is shaped as four plum blossoms.
