The atomizer is mainly used for manufacturing zinc powder or alloy zinc powder for purifying and removing impurities from a solution produced by a zinc hydrometallurgy plant.
Description
Technical field
The utility model relates to a kind of atomizer, relates in particular to a kind of atomizer of making zinc powder or alloy zinc powder.
Background technology
The method of making at present zinc powder has multiple, comprises the centrifugal skin method that becomes of jet atomization method, centrifugal atomizing method, chemical replacement method, strike, distillation condensation method, cutting method and up-to-date exploitation etc., and wherein the most frequently used method is the jet atomization method.Zinc powder impurity with this method preparation is few, even particle size distribution, production capacity height.But the shortcoming of jet atomization method is: the finished powder rate is low, as blows conventional powder, once become the powder degree in the ratio of+200 orders between-40 orders generally at 70-80%.
The utility model content
The purpose of this utility model is to provide a kind of powder formation rate height, thinner, the active stronger zinc powder of granularity or atomizer of alloy zinc powder made, to overcome above-mentioned deficiency.
For achieving the above object, technical solution of the present utility model is: a kind of atomizer of making zinc powder or alloy zinc powder, comprise the base and the cover plate that have blast pipe, it is characterized in that: described have blast pipe 1,1 ' base 6 and cover plate 4 between be provided with the band discharge opening 3 sealing flow distribution plate 7, this flow distribution plate is provided with flow splitter 9, there is charging aperture 8 at the center of cover plate 4, and this charging aperture is communicated with discharge opening 3.
The sealing flow distribution plate 7 of described band discharge opening 3 is stepped sealing flow distribution plates.
The beneficial effects of the utility model are:
1, compared with prior art, under the low pressure condition, the atomizing powder formation rate is higher,-40 orders (420 μ m) to the powder distribution rate of particle diameter between+200 orders (74 μ m) reaches more than 85%, production cost is low, and the metal recovery rate height is particularly useful for making-80 orders to+120 purpose zinc powder or alloy zinc powders.
2, the zinc powder that produces of the utility model or alloy zinc powder be because granularity is thinner, and specific area is bigger, and be active higher, so be particularly useful for the solution purification removal of impurities of zinc hydrometallurgy factory, avoids impurity anti-molten.
3, compressed air by the shunting of staged sealing flow distribution plate after, enter two separate cavitys that form in the atomizer respectively, pressure and flow can both independent regulation, and do not need to be respectively wind and the pressurization of secondary wind by two power-equipments.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1,1 '-blast pipe, the 2-upper plenum, the 3-discharging opening, the 4-cover plate, cavity under the 5-, the 6-base, 7-seals flow distribution plate, 8-charging aperture, 9-flow splitter, 10-screw.
The specific embodiment
Below in conjunction with accompanying drawing the utility model and the specific embodiment thereof are described in further detail.
Referring to accompanying drawing, the utility model comprises base and the cover plate that has blast pipe, it is characterized in that: described have blast pipe 1,1 ' base 6 and cover plate 4 between be provided with the band discharge opening 3 sealing flow distribution plate 7, this flow distribution plate is provided with flow splitter 9, there is charging aperture 8 at the center of cover plate 4, and this charging aperture is communicated with discharge opening 3.
The sealing flow distribution plate 7 of described band discharge opening 3 is stepped sealing flow distribution plates.
The zinc liquid or the alloy zinc liquid of fusion are injected discharge opening (3) by charging aperture (8), this charging aperture and discharge opening are interconnected, in fact constituted one " nozzle ", compressed air (hot blast or cold wind) is through airduct 1,1 ' enter in the atomizer, effect by sealing flow distribution plate 7, atomizer is separated into two cavitys of mutual isolation, be upper plenum 2 and following cavity 5, blast pipe 1 is by the discharge end confession " wind " of upper plenum 2 to " nozzle ", blast pipe 1 ' then passing through down, cavity 5 supplies " secondary wind " to " nozzle " discharge end, like this, zinc liquid or alloy zinc liquid in the end of discharge opening 3 by wind and secondary wind tangentially the jet zinc powder or the alloy zinc powder of beading shape, this kind zinc powder or alloy zinc powder fine size, productive rate height (powder between 40 orders-+200 order accounts for more than 85%), active strong, cost is low, be particularly useful for zinc hydrometallurgy factory and do the solution purification removal of impurities, avoid impurity anti-molten.Sealing flow distribution plate 7 of the present utility model is staged flow distribution plates, base 6 is connected by screw 10 with cover plate 4, secondary wind mixes with zinc mist that is gone out by a wind or alloy zinc mist, zinc mist or alloy zinc mist is evenly scatter, and zinc mist or alloy zinc mist are condensed into zinc powder or alloy zinc powder.
