Abstract
The invention discloses a special high-viscosity slurry granulating sprayer for production of a compound fertilizer. The special high-viscosity slurry granulating sprayer is a mechanically-powered sprayer. A slurry dispersing rotary tray is arranged at the outlet of a slurry feeding pipe; the outlet of the slurry feeding pipe is opposite to the side surface of the slurry dispersing rotary tray; the rotary tray has power for driving the rotary tray to rotate; during work, the slurry feeding pipe is used for feeding slurry to the side surface of the slurry dispersing rotary tray; the slurry fed to the side surface of the slurry dispersing rotary tray is dispersed into fog-like micro droplets by the effect of rotating force; the fog-like slurry leaving from the slurry dispersing rotary tray is sprayed on the surface of a material inside a granulator for coating granulation. The special high-viscosity slurry granulating sprayer is applied to a rotary cylinder type compound fertilizer granulator and is good in atomization effect; granulated particles are round and smooth and are qualified in strength; no other gas is charged into the granulator, so the internal pressure and the external pressure of the rotary cylinder are kept same; a draught fan for the granulator is saved; the power of a fan is saved; no dust is emitted to the environment; and the special high-viscosity slurry granulating sprayer adopts an environment-friendly technology.
Description
Technical field
This invention relates to the special high-viscosity slurry prilling spry of a kind of composite heat transfer, belongs to chemical fertilizer technical field.
Background technology
Granulation process is the important procedure of composite heat transfer, different prilling process and equipment is had according to material difference, there are sprinkling pelleting, slurry-spraying pelletizing, the granulation of atomization parcel etc., the slip that viscosity is lower is in the majority with gas atomization granulation, and the material after atomization drops on solid particle material surface, through parcel in layer, often wrap up primary drying once, particle is grown up gradually, after reaching the particle size of needs, obtains the suitable complex fertilizer product of granularity through dry further with screening.And the difficulty relating to high-viscosity slurry granulation is comparatively large, even if with swiftly flowing gas for decentralized medium, under flow at high speed gas drives, be also difficult to full-bodied pasty material is broken and atomization.
Here atomization gas used is generally high-temperature vapor or pressure-air; when using these gases to do atomizing grafting; also gas is brought into comminutor while granulation; and compound fertilizer granulating generally uses revolving drum granulator; the gas bringing comminutor into forms malleation in comminutor, and safety and health code requirement workshop must operate under pressure-fired, will be equipped with an air-introduced machine like this for comminutor; excessive gas is discharged to outside comminutor, tiny structure could be formed in comminutor inside.This process be discharged to by gas outside comminutor also can take away the dust that a part of gas atomization process is formed, and this part dust directly can not enter air, could discharge after needing dedusting qualified.
On the other hand, the slip higher to viscosity, the difficulty of fully atomization is very large, even if adopt high velocity air to be also difficult to be atomized, does not also have a kind of effective ways of applicable high-viscosity slurry atomization at present.
Summary of the invention
Content of the present invention is the special high-viscosity slurry prilling spry of a kind of composite heat transfer, and this atomizer is mechanical compared with traditional aerodynamic atomization, is to be atomized by high-viscosity slurry by machine power.
Specifically there is a High Rotation Speed mud dispersivity dish in slip feeder sleeve exit, and the outlet of slip feeder sleeve faces the side of this mud dispersivity dish, rotating disk is furnished with the power that it can be made to rotate; The outlet of slip feeder sleeve is 1-10mm with the distance of the side of mud dispersivity dish, and this distance is adjustable, and specifically according to phosphoric acid and gas product flow readjustment, slurry outlet and disc surfaces form the angle of 90 degree.The rotating speed of mud dispersivity rotating disk is adjustable; Its range of speeds is between 450-5000 rev/min.By slip feeder sleeve, slip is delivered on mud dispersivity rotating disk side during work; The vaporific miniature droplets that the slip delivering to mud dispersivity rotating disk side is dispersed under revolving force effect; The vaporific slip leaving mud dispersivity rotating disk is sprayed onto material surface in comminutor and carries out parcel granulation.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
The emery wheel that mud dispersivity dish 2 uses thickness larger, because emery wheel has the feature of wear resistant corrosion resistant, life cycle can be extended, and low price, can reduce costs, this emery wheel is directly connected on motor shaft, motor should be furnished with speed regulator, the side that slip feeder sleeve (1) outlet faces this mud dispersivity dish is installed, it is 1-10mm that slip feeder sleeve 1 exports with the distance of the side of mud dispersivity dish 2, and the distance of itself and emery wheel side is adjusted by set bolt, slip pipe and wheel face form the angle of 90 degree.
Embodiment
Mud dispersivity dish uses the plain wheel that thickness is 50mm, this emery wheel is directly connected on motor shaft, motor is furnished with speed regulator, the range of speeds is 450-1400 rev/min, installed the side that the outlet of slip feeder sleeve faces this mud dispersivity dish, the outlet of slip feeder sleeve is 2-6mm with the distance of the side of mud dispersivity dish, and adjusts the distance of itself and emery wheel side by set bolt, slip pipe and wheel face form the angle of 90 degree, namely radial installation.By slip feeder sleeve, slip is delivered on mud dispersivity rotating disk side during work; The vaporific miniature droplets that the slip delivering to mud dispersivity rotating disk side is dispersed under revolving force effect; The vaporific slip leaving mud dispersivity rotating disk is sprayed onto material surface in comminutor and carries out parcel granulation.
This mechanical type shower nozzle can be broken and be dispersed into vaporific miniature droplets by slip higher for viscosity; be used on drum-type compound fertilizer prilling machine; atomizing effect is good, and granulated pellet is mellow and full, and granule strength is qualified; because do not introduce other any gases in comminutor; rotating cylinder external and internal pressure can be kept consistent, eliminate comminutor air-introduced machine, save blower fan power; and not to environmental emission dust, be a kind of environmentally friendly technology.
