Description
Technical field
The utility model relates to a kind of prilling granulator, is a kind of differential prilling granulator of tower centrifugal spray for high-concentration compound fertilizer molten slurry granulating specifically.
Background technology
China is a large agricultural country, is also simultaneously a chemical fertilizers production and use big country.The chemical fertilizer industry of current China is in the updating and upgrading of a product, technological innovation, fertiliser production towards the new period of secondary processing and the agriculture service of profound level, the future development such as apply fertilizers scientifically.along with increasingly enlarging and the raising of fertilizer application person to applying fertilizers scientifically and being familiar with of domestic urea or ammonium nitrate final product throughput, the direct fertilising of the chemical fertilizer of single nutrient can not adapt to the requirement that applies fertilizers scientifically now: such as the utilization ratio of effective element in chemical fertilizer is on the low side, environmental pollution, soil compaction and farm crop are to requirement day by day of other elements etc., these weak points are along with the compound manure of multielement is constantly released, this series products share ratio on market certainly will will be dwindled, so be domestic nitrogenous fertilizer enterprises imperative development trend for the secondary deep processing to produce high-concentration compound fertilizer with urea or ammonium nitrate.
at present, allocate a certain proportion of phosphorus through heating in urea or ammonium nitrate, the solid-state pulverulent material such as potassium element and filler mixes and makes high density melt composite fertilizer, as when adopting the conventional centrifugal sprinkling pelleting of the single chemical fertilizer of transmission, when the compound manure of molten state enters in shower nozzle, because the effect that is rotatablely moved produces a centrifugal force vertical with the shower nozzle rotation, form the approximate parabolic liquid rotary structure of its section at nozzle cavity, the shower nozzle inwall bears the centrifugal pressure of this liquid state solid of revolution, the compound manure of melting sprays in the spray orifice by shower nozzle under the effect of centrifugal pressure, the melting fertilizer of ejection is subjected to the movement velocity of thread, the aerial wave characteristic of thread, resistance and the reasons such as the viscosity of itself and surface tension of meeting air fragment into drop, become solid-state spherical particle after the drop contraction is cooling, the volume of drop determines its required time from liquid to solid state cooling.Because composite fertilizer's concentration is higher, the traditional sprinkler heads spray orifice easily stops up, existing part shower nozzle is convenient to the ejection granulation of high density melting composite fertilizer by strengthening injection diameter, but melting fertilizer is subject to centrifugal pressure when going out spray orifice, be full of melting fertilizer in spray orifice, must increase through the drop of the larger spray orifice of diameter ejection, the macrobead drop that exceeds granulation cooling power cooling curing fully in air, to stick to bottom the granulation refrigerating unit, and cause industrial accident and productive rate to descend.
Summary of the invention
For the composite fertilizer's fused solution that solves high density easily stops up spray nozzle in the sprinkling pelleting process, spray orifice ejection drop can't be solidified into the deficiencies such as particle by effective cooling, it is a kind of simple in structure, compact that the utility model provides, can prevent effectively that spray nozzle from stopping up, spray orifice ejection drop cooling curing efficient is high, granulation production safety, efficient are high, the differential prilling granulator of tower centrifugal spray that the granulation quality is high.
the technical solution adopted in the utility model is: the differential prilling granulator of a kind of tower centrifugal spray, comprise motor, casing and prilling spry, motor is arranged at the casing upper end, the casing lower end connects prilling spry, motor in cross-under is supported on casing in, outer shaft be in transmission connection respectively distributor and the nozzle housing of prilling spry, it is characterized in that: cross-under distributor on described interior axle, distributor is provided with the scraper plate that polylith is evenly arranged along interior axle circumferential direction, the inner side edge of scraper plate is connected on distributor parallel with interior axle axis, the outer side edges of scraper plate and nozzle housing inner wall shape are coincide and are gap state, be evenly equipped with a plurality of spray orifices on nozzle housing.
Further, described scraper plate number is the 3-8 piece.
Further, described motor successively through support, bearing block support on the upper cover plate of casing.
Further, described motor stretches into and is provided with upper and lower tooth section on input shaft in casing, the upper and lower gear engagement on inside and outside axle in cross-under of upper and lower toothed portion.
Again further, described prilling spry is connected with outer shaft through the nozzle connecting joint chair, and distributor passes the nozzle connecting joint chair and is connected with interior axle through the distributor Connection Block.
Compared with prior art, the utility model has the advantages that:
1, motor is through the upper and lower gear of upper and lower tooth section's transmission, by the inside and outside axle rotation of upper and lower gear driven, inside and outside axle drives respectively distributor and the housing rotary of prilling spry, can regulate on the sense of rotation of distributor and housing and speed of rotation, have in the same way, the working order such as synchronized, reverse and not synchronized, can carry out choice for use according to the composite fertilizer melt of different concns, improve the device applicable performance;
2, in shower nozzle when distributor and housing reverse rotation, can accelerate the materials inside spray rate, coordinate distributor polylith scraper plate to be the rotation of little gap with inner walls in housing, in scraper plate is injected spray orifice on nozzle housing with melt material from its outer side edges tangential direction, melt material enters that the spray orifice amount is little and speed is high, effectively avoid high-concentration compound fertilizer to stop up in spray orifice, and the drop amount by the spray orifice ejection is little, be injected into thus in air to drop cooling fully, solidification effect is good, speed is fast, avoid industrial accident, further improve production capacity,
3, due in melt material with the solid suspension particle of a greater number, when rotating, nozzle housing easily forms the laminated segregation of solid liquid phase, thereby settlement influence is normally produced, the polylith scraper plate is installed on distributor, form a similar paddle whipped-up structure that mixes between distributor and nozzle housing during rotation, can effectively contain the solid liquid phase laminated segregation, avoid sedimentation phenomenon to occur; In addition, the melt material between shower nozzle inner-wall surface spray orifice and spray orifice prevents from accumulating contingent chemical polymerization for a long time with the polylith scraper rotary then break up, and can further improve the quality of products.
The utility model adopts the inside and outside axle of motor eccentric gearing to drive distributor and the nozzle housing rotation of prilling spry, polylith is set with the scraper plate of distributor rotation between distributor and nozzle housing, utilize the scraper plate rotation that melt material high speed, low measuring are carried out shower cooling curing granulation in the spray orifice of injecting on nozzle housing, it is simple in structure, compact, running is stable, spray orifice is difficult for stopping up, and the liquid droplets cooling curing is effective, efficient is high, can effectively guarantee product yield and quality.
