Abstract
The utility model discloses an anti-floating treatment device for coating controlled release fertilizer, which comprises a constant feeder, a solution preparation device, a flowmeter, a revolving drum and a finished product silo. The constant feeder is connected with the feeding port of the revolving drum. The solution preparation device is connected into the revolving drum by the flowmeter. The discharging port of the revolving drum is connected with the finished product silo. By using the device, the floating problems of the controlled release fertilizer in water can be perfectly resolved, and the problems of the uneven fertilization and nutrient loss caused by fertilizer floating are solved.
Description
Technical field
The utility model belongs to the controlled-release fertilizer production technical field, specifically relates to the anti-floating treatment unit of a kind of coating controlled-release fertilizer.
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 release and release control 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
The purpose of this utility model provides the fertile anti-floating treatment unit of a kind of controlled release.
The utility model realizes that the isolated plant of the fertile anti-floating processing of controlled release 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 beneficial effects of the utility model are: after adding anti-leafing agent on the release and release control fertilizer particle, anti-leafing agent diffusion rapidly spreads into the fertiliser granulates surface by this device, the anti-lipophilic termination coating surface of leafing agent molecule, and 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 not needing to change the fertile technical process of original controlled release, device is simple, and is easy to operate.In utilizing the utility model technology, be to utilize the waste heat of the coating controlled-release fertilizer that streamline gets off will prevent that leafing agent is distributed evenly, rapidly to be diffused into the fertiliser granulates surface, can save energy consumption.
Description of drawings
Fig. 1 is the apparatus structure synoptic diagram that the utility model is realized the fertile anti-floating processing of controlled release.Wherein, 1. constant feeder, 2. solution device for formulating, 3. under meter, 4. rotary drum, 5. finished product bin.
Embodiment
Specify the technical solution of the utility model and effect below in conjunction with embodiment and test example, but be not limited thereto.
Embodiment 1
As seen from Figure 1, the utility model realizes that the isolated plant of the fertile anti-floating processing of controlled release comprises: constant feeder 1, solution device for formulating 2, under meter 3, rotary drum 4 and finished product bin 5, described constant feeder 1 connects the charging port of rotary drum 4, described solution device for formulating 2 connects to advance rotary drum 4 by under meter 3, and the discharging port of described rotary drum 4 connects into product feed bin 5.Described solution device for formulating 2 can be that pressure-pot adds air compressor machine, also can be the storage tank fluid filling pump; Described constant feeder 1 comprises weighing belt and travelling belt.
Utilize embodiment 1 described device to carry out the anti-floating processing of controlled release fertilizer.Anti-leafing agent uses water-soluble azone, and makes thinner with dehydrated alcohol.Solution allocation device 2 adopts pressure-pot and air compressor machine, and product addition per ton is respectively 0.5kg, 1kg, 2kg, 3kg, and the concrete operations step is as follows:
The first step: water-soluble azone of 50kg and 5kg dehydrated alcohol are added mixing in the pressure-pot, shut charging valve, open air compressor machine, adjusting pressure-pot pressure is 1-2MPa.
Second step: start constant feeder 1, the coating sustained-controll-release fertiliser is delivered into rotary drum 4 by travelling belt, open liquid injection valve, adjust under meter 3 flows, water-soluble azone is sprayed on the fertiliser granulates, along with the rotation of rotary drum 4, fertiliser granulates constantly moves, and water-soluble azone is sprawled diffusion rapidly and uniformly on the fertiliser granulates surface.
The 3rd step: fertilizer enters finished product bin 5 finish the spraying of water-soluble azone in rotary drum 4 after, waits for the packing warehouse-in.
Experimental example 1
The embodiment finished product of each water-soluble azone addition among the embodiment 1 is all got 1kg as sample.Effect for the different additions of more water-soluble azone, now do a pair of: from each sample, choose 200 granulated fertilizer material at random than test (comparing) with the controlled release fertilizer that does not add anti-leafing agent, from the funnel that is placed on the bucket mouth, knock down in the water, experimental result sees Table 1, No. 1, control treatment does not add anti-leafing agent, and its floatability is 10.5%, No. 2 are handled the fertilizer its floatability is 3.5%, and other handle neither floating; Fertiliser granulates outward appearance aspect, 1,2, No. 3 processing is all good, and No. 4 the processing outward appearance is moist slightly, fertiliser granulates surface noresidue liquid, the adhesion of No. 5 processing fertiliser granulates.As seen all are best with 3, No. 4 effects in handling, and therefore the suitableeest usage quantity of water-soluble azone is 1-2kg/t.
Anti-floating effect in the water that the different additions of the water-soluble azone of table 1 are handled
| Numbering | Water-soluble azone consumption (kg) | Drop into fertilizer (grain) | Floating fertilizer (grain) | Its floatability (%) | Outward appearance |
