Description
Technical field
The utility model relates to a kind of spray dryer shower nozzle, particularly relates to a kind of hydronic centrifugal spray dryer shower nozzle.
Background technology
Spraying dry is a kind of method that systematization technique is applied to dry materials.Its operation principle be by solution, suspension or emulsion through atomization after, contact with hot-air or other dry gas in the drying chamber, by solvent or dispersant rapid vaporization, obtain dry products.Its outstanding advantages is rapidly dry, and can directly make solution, emulsion is dried to powdery or particulate preparation, production efficiency is high, and operating personnel are few, and production capacity is large, is one of drier throughput the greater.Spraying dry is easy to adjust, can change operating condition to control the quality index of product, as size distribution, moisture content, biologically active, dissolubility, color etc. in a big way.It is particularly useful for responsive to temperature, can not the material of long-time heating, can realize controlling the pattern of secondary or high order particle simultaneously.
Shower nozzle is one of core component of spray drying device, determines the operational efficiency of equipment and the quality of product to a great extent.Centrifugal sprinkler, pressure type shower nozzle gentle streaming shower nozzle are conventional spraying dry atomising devices.Wherein, pressure nozzle utilizes high pressure to be atomized by material, and misty liquid droplets directly contacts with hot-air, and carry out heat exchange, the short time completes drying.This shower nozzle can obtain less product cut size, but the topography uniformity of powder is bad, and size distribution is wide.Air-flowing type shower nozzle utilizes high velocity carrier gas by the atomization of liquid, has then mixed drying with hot gas.This shower nozzle production capacity is large, but to the pattern of powder and Task-size Controlling not strong.Centrifugal sprinkler is the disk utilizing horizontal direction to make High Rotation Speed is that liquid carrying to be dried supplies kinetic energy, makes it to throw away at a high speed, forms film, filament or drop, by hot gas drying in hothouse.Such shower nozzle obtains the narrow diameter distribution of product, but cannot obtain larger or less meso-position radius.Centrifugal sprinkler has the advantages such as output is large, stability is high, easy care, is most widely used in large-scale spray drying device.But operationally, Centrifugal dispersion impeller temperature is higher for centrifugal sprinkler, has part dispersant and evaporated when slurry enters dispersion impeller, causes component segregation, generate slag, and the problem such as pattern is bad.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of hydronic centrifugal spray dryer shower nozzle, it utilizes cooling agent to cool impeller, makes slurry before leaving dispersion impeller, keep composition stable, realizes the drying process with atomizing process that degree of controllability is higher.
For this reason, the technical solution of the utility model is as follows:
A kind of hydronic centrifugal spray dryer shower nozzle, comprise hollow drive shaft, hollow impeller, be connected to feeder on hollow impeller and cooling agent reclaims ring, described hollow impeller comprises upper cover plate, lower cover and is arranged at the multiple hollow blades between upper and lower cover plate, described lower cover is hollow and its upper plate is fixedly connected with hollow drive shaft, and inside is cooling liquid flowing channel; Described upper cover plate is cavity ring body, and its internal diameter is greater than the external diameter of described hollow drive shaft; Described cooling agent is reclaimed ring and is connected by mechanical sealing member with the inward flange of described upper cover plate; Described multiple hollow blade is fan-shaped, the lower plate of the corresponding upper cover plate of its hollow position and the upper plate place of lower cover all through; Arcwall between described multiple hollow blade is provided with material outlet.
Described feeder is the tubular ring with described hollow drive shaft coaxial line, and described tubular ring is also provided with charging aperture and is connected to the discharge nozzle of described lower cover.
The shape of the hollow position of described hollow blade is triangle.
Described cooling agent reclaims ring and is also provided with coolant collecting container.
Described multiple hollow blade is uniformly distributed along the circumference of described hollow impeller.
This hydronic centrifugal spray dryer shower nozzle has the advantage that structure is simple, be easy to maintenance.This shower nozzle can control the temperature of dispersion impeller well, makes slurry before leaving impeller, and composition is stable, realizes the drying process with atomizing process that degree of controllability is higher.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in detail.
As shown in figs. 1 to 6, a kind of hydronic centrifugal spray dryer shower nozzle, comprise hollow drive shaft 3, hollow impeller 1, be connected to feeder 4 on hollow impeller 1 and cooling agent reclaims ring 2, hollow impeller 1 comprises upper cover plate 6, lower cover 7 and is arranged between upper and lower cover plate along the equally distributed multiple hollow blade 5 of its circumference, lower cover 7 is hollow and its upper plate is fixedly connected with hollow drive shaft 3, and inside is cooling liquid flowing channel; Upper cover plate 6 is cavity ring bodies, and its internal diameter is greater than the external diameter of hollow drive shaft 3; Cooling agent is reclaimed ring 2 and is connected by mechanical sealing member with the inward flange of upper cover plate 6; Multiple hollow blade 5 is fan-shaped, the lower plate of the corresponding upper cover plate 6 of its hollow position and the upper plate place of lower cover 7 all through; Material flow path is between multiple hollow blade 5; The sidewall of hollow impeller 1 is provided with material outlet 8 between adjacent two hollow blades 5.Feeder 4 is the tubular ring with hollow drive shaft 3 coaxial line, and this tubular ring is also provided with charging aperture and is connected to multiple discharge nozzles of lower cover 7.The shape of the hollow position of hollow blade 5 is triangle, and this hollow position also can be other shape as required.Cooling agent reclaims ring 2 and is also provided with coolant collecting container.
