Description
Technical field
The present invention relates to the injection apparatus on the water atomization metal dust production line.
Background technology
The non-ferrous metal milling method has atomization, and atomization belongs to mechanical powder process method, and this method adopts and directly smashes liquid metals or alloy and make powder.Atomization comprises second-rate atomization, is divided into gas atomization and water atomization.All adopt inert gas atomizer for global type metal dust (cupric and copper alloy powder) conventional production methods, what adopt is the circumferential weld nozzle, inert gas manufacturing equipment costliness, environmental requirement height in the technological process, factory building is up to more than the 14m, more than the atomizing bucket 7m, and atomising device requires not have and leaks, and dust arrester installation etc. be arranged.Another major defect is that the spheric granules particle diameter is on average bigger, and the fine powder rate is lower, and-30 μ m global type powder are approximately about 30%, and the following spherical powder of-30um can't carry out suitability for industrialized production at all.The production cost height, production process has dust pollution.
The water atomization atomizing medium is a water, and heat transfer rate is very fast between water and the metal, and the atomizing homogeneous media distributes under the high-pressure situations in order to reach, and selects the annular distance nozzle.The powder that the traditional structural design of water atomizing nozzle can only be produced is irregular (or oval, teardrop shaped (or claiming torispherical)) can not be produced the metal dust of the global type (all being spherical) that has particularity and require from integral body to the individuality.Its water atomizing nozzle circumferential weld nozzle processing difficulties, the assembling die structure requires height when mounted, and concentricity is low excessively, causes atomizing medium skewness, out-focus, can not effectively atomize.
Summary of the invention
The objective of the invention is: the injection apparatus that the water atomized spherical metal powder that provides a kind of small investment, atomizing medium to be evenly distributed, to focus on, can effectively to atomize is produced.
Concrete structural design scheme is as follows:
The injection apparatus that water atomized spherical metal powder is produced comprises Spray-nozzle carrier, sprayer body and tightens up nut that sprayer body is fixedly mounted on the Spray-nozzle carrier by tightening up nut; Sprayer body axially middle part is the metal liquid stream through hole, and an end is the liquid inflow entrance, and the other end is horn-like outlet, and its horn-like ring wall is provided with water jet; Cavity between sprayer body periphery and the Spray-nozzle carrier is a water channel, it is characterized in that:
The horn-like ring wall of described sprayer body is provided with 4-8 water jet, is respectively equipped with the column fountain head in each water jet, and fountain head extends outward outside the horn-like end face of sprayer body,
The spray-hole aperture of described fountain head is a slotted eye, and its spray-hole aperture long axis length is the 1-3 millimeter, and minor axis length is the 0.5-1.5 millimeter, and the major axis of the spray-hole of 4-8 shower nozzle is parallel.
The major axis horizontal parallel of the spray-hole of described fountain head or vertically parallel.
Between the water jet on described fountain head and the sprayer body for being threaded.
Useful technique effect of the present invention is embodied in following several aspect:
1, the present invention is by the improvement to existing injection apparatus, realized that employing water atomization technology can produce the global type metal dust, and-30 μ m fine powder rates are more than 65%.
2, compare with the production of traditional spheroidal powder inert gas atomizer method, the equipment investment of water atomization production global type metal dust is few, work simplification, simple to operate, this method is used to produce copper powder and alloyed powder can satisfy outside production powdered metal parts, the friction material, also can be satisfied with the handicraft application, electrocondution slurry, scolder of requirements at the higher level etc., can replace the similar global type metal dust product that the inert gas atomizer method is produced fully.
3, among the present invention because shower nozzle is a consumable accessory, adopts between the water jet on shower nozzle and the sprayer body to be threaded, be convenient to the loading and unloading replacing of daily production in keeping in repair.
