Description
Technical field
The utility model relates to a kind of magnetic materials production equipment, can significantly improve the air-mixing nozzle of granulation effect in especially a kind of magnetic material mist projection granulating process.
Background technology
In the manganese-zinc ferrite particle material production process of prior art, particulate material adopts mist projection granulating production basically, and mist projection granulating mainly contains press atomization and centrifugal spray dual mode.The former production capacity is big, but granulated pellet is bigger, and the distribution of particles broad often has irregular ball or hollow ball to produce, and is not suitable for small-sized assorted type product compacting.Latter's particle is thin, distributes to concentrate evenly, mostly be full particle, but production capacity is little, not quite can satisfy the large-scale production requirement.Adopt under the prerequisite of press spray granulation production in the prior art overwhelming majority,, will the improvement of grain forming (compacting of particularly small-sized assorted type product) be very helpful if can obtain the particle of centrifugal spray granulation effect.Open day is on August 10th, 2005, publication number be the Chinese patent file of CN1652876A disclose a kind of in hybrid air atomizing spray nozzle assemblies, comprise the vertical liquid flow path that ends at liquid port, flow along the predetermined axial line guiding liquids being used for; The a plurality of crossing transversal passage that extends and intersect with this predetermined axial line perpendicular to this predetermined axial line, each this transversal passage ends at an outlet at each end, this transversal passage qualification one is positioned at first shock surface in the downstream of this liquid port, so that make to impact the dispersion train that the liquid flow on it becomes side direction to launch, this dispersion train scatters through this transversal passage; Be arranged to outlet with respect to this transversal passage and be the air ring of the relation of encirclement, this air ring is oriented such that air discharges along downstream direction, so that the fluid that bump scatters through the outlet of this transversal passage; And the expansion chamber that is arranged in this transversal passage and this air ring downstream, this expansion chamber is communicated with the nozzle delivery port.In addition, open day is on September 19th, 2007, publication number is that the Chinese patent file of CN101039757A discloses a kind of improved internal mix air atomizing nozzle assembly, be suitable under less compressed air demand, working, the jet blower device comprises the fluid passage that is used for the close collision pin of guiding liquids stream, air director is set to form the annular compression air duct around liquid stream, so that bump and atomizing are from the dispersing liquid of impact surfaces lateral propagation.In order to strengthen the atomization of liquid, air director limits the air flow openings of relative narrow width, so that roughly quicken the pressure of flow of atomization air and increase flow of atomization air, the collision pin is formed with big relatively main impact surfaces and auxiliary impact surfaces parallel, that be positioned at the downstream, auxiliary impact surfaces promotes that liquid particle further divides, and prevents that accumulation of fluid is around collision pin bottom.These two kinds of nozzle arrangements complexity, cost is very high, and only is suitable for the spraying of neat liquid such as water, is not suitable for the mist projection granulating process of magnetic material.
The utility model content
The utility model is thick for press atomization particle in the existing magnetic materials production process of solution, skewness, the problem that irregular ball and hollow ball are many and provide a kind of spraying granule thin, distribute concentrate, irregular ball and hollow ball be few, helps improving a kind of air-mixing nozzle of product suppression performance.
The utility model is to reach the concrete technical scheme that above-mentioned technical purpose adopts to be: a kind of air-mixing nozzle, comprise liquid supplying passage and gas delivery channels, described air-mixing nozzle is column structure, liquid supplying passage is positioned at the central authorities of column structure, the port of export of liquid supplying passage is provided with the liquid spout, gas delivery channels forms cross section around liquid supplying passage and is circular circular passage, the port of export of gas delivery channels is provided with gas spout, gas delivery channels is provided with cowling panel near the position of gas spout, cowling panel is provided with rectification hole, the downstream of rectification hole is provided with guide plate, and gas spout is around the downstream of liquid spout and directional liquid spout.Be provided with in the periphery of liquid (feed liquid) shower nozzle of routine and carry compressed-air actuated gas delivery channels, and cowling panel is set at the end of gas delivery channels, rectification hole is set on the cowling panel, the downstream of rectification hole is provided with guide plate, compressed air is through rectification hole, forms behind the guide plate to have stable, the high-speed air flow of shape rotation evenly and in the shape of a spiral.This high-speed air flow is by impacting the feed liquid of liquid spout ejection, feed liquid is atomized again, make the feed liquid atomizing more thorough, drop is littler, interferes and reduces, and resulting granules material particle is thinner, distribute and concentrate, flowability is better, thereby can improve the suppression performance of product effectively, improves the quality of product.
As preferably, cowling panel is structure confining gas transfer passage in the form of a ring, and the rectification hole on the cowling panel is 8 to 16, evenly distributes in the form of a ring on cowling panel.The effect of rectification hole is that gas is rectified into the air-flow that multiply is concentrated relatively, thereby forms the more strong impact of feed liquid, makes drop littler, and resulting granules material particle is thinner.
As preferably, guide plate is arranged on the side end face of cowling panel obliquely, guide plate is between two adjacent rectification hole, the fixed edge direction of guide plate makes progress in the footpath of cowling panel, the quantity of guide plate is identical with the quantity of rectification hole, the angle of inclination of all guide plates is all identical, and evenly distributed along the cowling panel rotation of circulus, and the angle of inclination between guide plate and the cowling panel plane is 35 to 55 degree.The effect of guide plate is to make the air-flow through cowling panel change direction, makes it have tangential component, and multiply gas formation swirling eddy, forms " tearing " mechanism to feed liquid, helps the refinement of feed liquid drop.
As preferably, the liquid supplying passage end is provided with expansion chamber, and the port of export of expansion chamber shrinks and forms the liquid spout.Because have certain pressure in the feed liquid course of conveying, this pressure is unfavorable for the dispersion of feed liquid, expansion chamber has the effect of release, and the feed liquid decompression is disperseed, and helps the atomizing of feed liquid.
As preferably, the gas delivery channels radial contraction in guide plate downstream forms the gas spout of pyramidal structure, and the port of export of air-mixing nozzle is round table-like structure, and the cone-apex angle of gas spout pyramidal structure is 60 to 120 degree.Air-flow can the be led center of liquid stream of the gas spout of pyramidal structure makes air-flow fully contact with liquid stream, and it is even that feed liquid is atomized, and the round table-like structure of nozzle exit end is a kind of and the suitable structure of pyramidal structure.
The beneficial effects of the utility model are: it is thick that it has solved in the magnetic materials production process of prior art the press atomization particle effectively, skewness, the problem that irregular ball and hollow ball are many.The utility model spraying granule is thin, distribute concentrate, irregular ball and hollow ball be few, helps improving the product suppression performance, can improve the quality of products significantly, has tangible economic benefit.
