Abstract
The effect of this invented method is to separate the solid phase granules settled between holes of spray disk and make the granules spray out with the molten liquid. At a distance of 0.5-3 mm from the spray disk, there is a stirrer, and at 30-80 mm above the stirrer, there is a propeller. The propeller and stirrer are coaxial and fixed on the lower end of axle. Advantages are that high viscosity composite molten liquid containing suspended granules can freely pass through the spray nozzle, it is novel in design, convenient in operation, the produced composite fertilizer granules are round in shape, uniform in size and high in strength.
Description
The present invention relates to a kind of rotatable stirrer that is used for the fixedly spray disc type comminutor of the cold technology of melt method, and its effect is that the solid phase particles that will be deposited between the spray dish Kong Yukong stirs out, and makes it to spray with liquation from spray orifice.
Background technology of the present invention: existing centrifugal granulator drives the prilling spry rotation by the main shaft that is vertically mounted in the transmission mechanism; fused solution by feed system to shower nozzle bottom; under action of centrifugal force; fused solution is the hyperbolic wire and is attached at the shower nozzle inwall and rotates synchronously with shower nozzle; under action of centrifugal force; spray the spray orifice of fused solution from the shower nozzle generatrix, the jet chance air of ejection is broken into and drips, the poly-spherical particle that becomes in the landing process.Then can't obtain expected effect for the full-bodied composite fertilizer's liquation that has suspended particulate with above-mentioned technology.Reason is that existing comminutor can't overcome the blocked problem of spray orifice, will have a strong impact on the quality of granulation and the discharging that increases dust and strengthen injection diameter.Simultaneously, strengthen injection diameter and can not thoroughly solve the blocked problem of spray orifice, because the plastic properties that the liquation of melt method combination process has time to time change than the viscosity and the compound mixture thereof of high thousands of times of single urea.
Purpose of design of the present invention: design a kind of compound liquation that makes high viscosity have the suspension particle and can cross the fixedly spray disc type prilling spry and the prilling process that are used for melt method oil cooling technology that sprays with liquation in the spray orifice of prilling spry smoothly.
Design of the present invention: key position of the present invention is that there are a rotatable stirrer and propeller in spray dish top.The effect of agitator is to stir to open and make it to spray with liquation from spray orifice being deposited in solid phase particles between spray dish Kong Yukong.In order to realize this purpose: 1. in the technical scheme design: housing (10) is a hollow double-layer seal metal structure, filling heat-conductive oil (1) in double-level-metal, conduction oil is by several electric heaters (9) heating of housing inner bottom part, and the oil temperature is by temperature sensing controller control (this technology belongs to prior art).The bottom of housing is provided with add, drain the oil stifled (2).Shaft (12) is installed in the center of housing (10), the belt pulley on top (13) is dragged by variable-frequency motor, the bottom is provided with an agitator (6) apart from 0.5～3 millimeter place of spray dish, agitator has 2～6 sheets or thread metal, and purpose will be deposited in solid phase particles between spray dish Kong Yukong and stir to open and make it to spray with liquation from spray orifice.Because the viscosity of composite fertilizer's liquation is higher than urea and thousands of times of ammonium nitrate liquations and wherein contains the solid particle of some, these particles settlings are on the face between spray dish (7) Kong Yukong, prolongation along with the time, the distinctive plastic properties generation of compound liquation chemical polymerization, anxious poly-increase of viscosity, thoroughly blocked until spray orifice.And it is influential to the granulation quality to strengthen injection diameter, the distance of dwindling between the Kong Yukong may make jet bump against in the landing process again, for solving this difficult problem, 30～80 millimeters places are provided with a propeller (4) on agitator top, propeller is made up of the paddle of 2～4 band angles, paddle is welded on to be adjusted on the nut (5), its propelling angle of liquation of looking different formulations is different, under the effect of propeller (4) axial thrust, with precipitum under the well-mixed situation, liquation can pass through spray orifice fast at agitator (6).Spray dish (7) is positive circular flat shape metallic plate, have some equidistant and isometrical spray orifices or not equidistant and isometrical spray orifice thereon, the height of liquid layer in the control container, the pressure of the liquation each point of spray dish (7) top is consistent substantially, so the fluid column that penetrates from each spray orifice theoretically should be consistent, therefore the process of its fracture balling-up should be a basically identical also, that is to say that the granulation effect is better than the alternate manner, is in particular in that particle is mellow and full, big and even, intensity can reach 100 newton.Propeller is coaxial with agitator, and its axial distance is adjusted by regulating adjustment nut (5).The rotating speed of belt pulley (13) is by the frequency converter step-less adjustment.Boss in the belt pulley (13) touches mutually with the upper surface of graphite bearing (3) on being positioned at bearing box (11) Baltimore groove platform, and touch mutually with bearing box Baltimore groove platform the upper surface that is positioned at the graphite bearing (3) of bearing box (11) bottom, lower surface and shaft (12) shaft shoulder touch mutually.Belt pulley (13) top has the spring Baltimore groove, spring (14) is enclosed within the spring Baltimore groove, gland passes shaft (12) and is positioned on the spring, and locking nut (15) is screwed on the shaft and the gland lock is pressed in itself and fused solution (8) in the housing are sealed.2. the fixedly spray disc type comminutor prilling process that is used for melt method oil cooling technology; the high viscosity melting composite fertilizer that is positioned at insulation shell and insulation prilling spry is under the effect of propeller axial thrust; agitator with high viscosity melting composite fertilizer under the well-mixed situation of precipitum, make its liquation spray orifice by prilling spry fast.
The present invention compares with background technology, and the one, spray dish top agitator and angle of rake design, the compound liquation that can make high viscosity have the suspension particle can spray with liquation in the spray orifice of prilling spry smoothly excessively; The 2nd, structural design novelty, uniqueness, simple, practical and easy to operate, and institute's compound fertilizer granules of making is mellow and full, size is even, intensity is good---can reach 100 newton; The 3rd, cost is low, is convenient to promote.
