Technical field
The present invention relates to the fertilizer production device technical field, specifically the fluidizing fluid-bed coating production system of a kind of continuity slow-release or control-release fertilizer.
Background technology
Slow-release or control-release fertilizer comprises two kinds of interior slowly-releasing and outer slowly-releasings, interior slowly-releasing is that the interpolation inhibiter is that fertilizer efficiency slowly discharges in fertiliser granulates, the outer slow-release fertilizer that China gives priority to is to coat a skim on the surface of waste material particle, fertilizer efficiency is slowly discharged, improve the utilization ratio of fertilizer, existing slow-release fertilizer production unit mostly is the fluidizing fluid-bed and rotary drum coating of intermittent type, in recent years domestic-developed rotary drum fluid-bed.The fluidizing fluid-bed coating effect of intermittent type is better, but owing to being batch production, single device throughput is less, and level of automation is relatively poor, can't realize mass-producing.Although the rotary drum coating can be realized continuous production, the coating quality is more fluidizing fluid-bed poor, and the Controlled Release Fertilizer controlled release time of production is shorter.Although the rotary drum fluid-bed rotary drum coating of comparing has improved the coating quality; serialization, large-scale production have been realized simultaneously; but rotary drum fluid-bed less in fluidised space; the fertiliser granulates of coating is in the situation that the probability of collision of complete drying and barrel is not larger; also cause the adhesion between the coated granule, still can't guarantee the coating quality fully.
Summary of the invention
The fluidizing fluid-bed device of continuity slow-release or control-release fertilizer that the objective of the invention is to overcome the deficiencies in the prior art and a kind of coating serialization of seething with excitement is provided, improves the coating quality, can accomplish scale production.
For achieving the above object, the technical solution used in the present invention is: the fluidizing fluid-bed coating production system of continuity slow-release or control-release fertilizer, comprise feeding device, material-spraying device, air-supply arrangement, the finished product generating apparatus, exhaust gas processing device and fluidizing fluid-bed, the described fluidizing fluid-bed air compartment that comprises, boiling-house, opening for feed, discharge port, fluidizing fluid-bed lower end is provided with blast inlet, fluidizing fluid-bed bottom is provided with air compartment, the upper end of described air compartment is provided with card, air distribution plate has been installed in the air compartment, be laid with blast cap on the card, the card upside is boiling-house, the boiling-house upper end is provided with opening for feed, shower nozzle is installed in the boiling-house, the boiling-house upper end is expanding reach, the bottom of expanding reach is equipped with discharge port, the top of expanding reach is top cover, top cover top is air outlet, described feeding device is connected to fluidizing fluid-bed opening for feed, described discharge port is connected with the finished product generating apparatus, described shower nozzle connects material-spraying device, described blast inlet is connected with air supply plant, and described exhaust gas processing device is connected to the air outlet place.
Further, it is cylindric that described air compartment is that top is, and the bottom is the inverted cone shape.
Further, described air distribution plate is installed in described turbination inside.
Further, described feeding device comprises raw material lift, raw material hopper, belt weighing balance, and the belt weighing balance is sent raw material into opening for feed.
Further, described material-spraying device comprises emulsification pump, thawing vat, whitewashing groove, and the whitewashing groove connects shower nozzle.
Further, described air-supply arrangement comprises hotblast stove and calorifier, and described calorifier connects blast inlet.
Further, described finished product generating apparatus comprises that finished product lift, finished product hopper, packing claim, the finished product hoist installation is at the discharge port place.
Further, described exhaust gas processing device comprises that tornado dust collector, exhaust fan and chimney are connected successively, and described tornado dust collector are connected to the air outlet place.
After adopting said structure; beneficial effect of the present invention is: the invention solves the problem that mass-producing can't be produced, be realized to the boiling coating continuously; can accomplish continuous production; avoided simultaneously the rotary drum coating to produce short defective of Controlled Release Fertilizer controlled release time; compare with rotary drum fluid-bed coating; the present invention has reduced fertilizer during coating and the probability of collision of barrel, has improved the coating quality.The present invention integrates granulated fertilizer spraying, coating curing, can realize extensive, the serialization production of slow-release or control-release fertilizer, being sprayed in the process that particle seethes with excitement up and down of fertilizer finished, and finished simultaneously the curing of coating, can not produce adhesion each other, the breakdown of coating that causes because of particle and equipment friction can not occur yet, can greatly improve the sustained release performance of slow-release or control-release fertilizer, charging and discharging are carried out simultaneously, have accomplished serialization production, the ability of the equipment of giving full play to has reduced facility investment.
