Description
Technical field
The invention belongs to the controlled-release fertilizer production technical field, specifically relate to a kind of coating controlled-release fertilizer anti-floating processing method and device, the controlled release fertilizer of handling through this method is particularly suitable for applying at aspects such as paddy rice, lotus and fish ponds.
Background technology
Controlled release fertilizer makes it to absorb basic synchronization with crop nutrition content by the regulation and control to the nutrient release rate, can improve the fertilizer nutrient utilization ratio greatly, improve quality of agricultural product, reduce widespread pollution from the overuse of fertilizers and pesticides in rural area, meet the requirement of national sustainable development strategy, so sustained-controll-release fertiliser has become one of main direction of 21 century fertilizer industry development.Controlled release fertilizer is extensively approved with respect to the high-performance of common fertilizer at present, scientific research institutions such as Beijing agricultural academy of sciences, Shandong Agricultural University have also captured the technical barrier of controlled release fertilizer, and Shandong Kingenta Bio-engineering Stock Co., Ltd. takes the lead in capturing its industrialization barrier, realized the conversion of science and technology to productivity, success has been applied to controlled release fertilizer on the field crop, and the market reflection is good.
Coating controlled-release fertilizer all will add the oily matter modification in process of production.The organic polymer coating controlled-release fertilizer adds oily matter in the coating liquid layoutprocedure be in order to change the rheological property of material, to make it to be easy to film forming, and make the smooth densification of coating.Because the bag Thio Urea adds saturating property and the fragility that the oiliness encapsulant improves film, when being applicable to these fertilizer in paddy field or the pond, all can have a certain proportion of fertilizer to swim on the water surface.Therefore, if use controlled release fertilizer in paddy rice or pool, the fertilizer that swims on the water surface can flock together with the wind, is unfavorable for uniform of application, also may waft with current, causes the wasting of resources.In order on wet crops such as paddy rice, to apply controlled release fertilizer, need to solve its floating problem in water.
Summary of the invention
One of purpose of the present invention provides the fertile anti-floating processing method of a kind of controlled release, can solve the floating problem of controlled release fertilizer in water.
Two of purpose of the present invention provides a kind of device of realizing the fertile anti-floating processing method of controlled release.
The inventive method is that anti-leafing agent is coated onto the coating controlled-release fertilizer particle surface, thereby realizes coating controlled-release fertilizer buoyant effect not in water, comprises that step is as follows:
A, will prevent that leafing agent adds in the solution device for formulating;
B, controlled release fertilizer is delivered in the rotary drum by constant feeder;
C, by the control of under meter, will prevent that leafing agent sprays to the coating controlled-release fertilizer particle surface, anti-leafing agent is distributed evenly, rapidly and is diffused into the fertiliser granulates surface, anti-leafing agent consumption is the 0.05-0.3% of coating controlled-release fertilizer quality;
The finished product that comes out from rotary drum enters finished product bin, waits for the packing warehouse-in.
The molecular structure of anti-leafing agent is that an end is a hydrophilic radical described in the steps A, and the other end is the anti-leafing agent of lipophilic group, preferably water dissolubility azone; For ease of more uniformly spraying, can make the thinner of water-soluble azone with dehydrated alcohol.
When leafing agent is prevented in spraying, can use two-fluid shower nozzle or single fluid shower nozzle, also can not use shower nozzle, directly be sprayed onto on the fertiliser granulates by tubing.
In the fertile anti-floating processing method of aforementioned controlled release, will prevent among the step C that leafing agent sprays to before the coating controlled-release fertilizer particle surface, will prevent that earlier leafing agent is heated to 30-60 ℃, spraying effect can be better.Certainly, also can directly utilize the waste heat (30-60 ℃) of the coating controlled-release fertilizer that streamline gets off will prevent that leafing agent distributes evenly, rapidly and be diffused into the fertiliser granulates surface, thus save energy consumption.
The present invention realizes that the isolated plant of aforesaid method comprises: constant feeder, solution device for formulating, under meter, rotary drum and finished product bin, described constant feeder connects the charging port of rotary drum, described solution device for formulating connects into rotary drum by under meter, and the discharging port of described rotary drum connects into the product feed bin.
The invention has the beneficial effects as follows: by present method after adding anti-leafing agent on the fertile particle of controlled release, anti-leafing agent diffusion rapidly spreads into the fertiliser granulates surface, the anti-lipophilic termination coating surface of leafing agent molecule, a hydrophilic end is outside, after knocking down this fertilizer in the water, the rapid submerged of fertilizer meeting can perfectly solve the floating problem of controlled release fertilizer in water, and by the uneven and nutrient loss problem of the floating fertilising that brings of fertilizer.And this method do not need to change the fertile technical process of original controlled release, and device is simple, and is easy to operate.
