Abstract
The present invention relates to a granular preparation containing a pesticide compound fertilizer, and a preparation method and a device thereof. The granular preparation simultaneously has the characteristics of pesticide granular preparations and compound granular preparations. A nitrogen fertilizer, a phosphorus fertilizer and a potassium fertilizer in a certain weight percentage are crushed, and then are added to a mixing machine together for uniform mixture; the mixture is put into a granulator to meet with modified polyvinyl alcohol formal glue solution sprayed quantitatively to form granules under the condition of continuous rolling; then, the granules are put into a shaker drier for drying, and the granular preparation containing a pesticide compound fertilizer is prepared by sieving and cooling. The present invention has the advantages of simple preparation method and short technical process and can reduce production cost and use cost.
Description
The present invention relates to a kind of granulated compound fertilizer containing pesticide that helps crop growth and preparation method thereof.
For making the farm crop normal growth, not only need to replenish the nutritive element in the soil, but also will apply the agricultural chemicals of prevention and elimination of disease and pests.But apply various fertilizer and agricultural chemicals respectively, spend a large amount of time and labor force.Present expert both domestic and external is being devoted to study various compound manure, particularly contains the compound manure of agricultural chemicals and soil improvement agent.The fertilizer of polymkeric substance of nitrogenous, phosphorus, potassium and the naphthylamines and the maleic anhydride of plant-growth has been proposed to impel as United States Patent (USP) 4021220; For improving the physical properties of fertilizer, prevent caking or control dissolution rate, improve fertilizer utilization ratio, be convenient to machinery and use, developed granulated fertilizer and band coating fertilizer again.Introduced a kind of granulated product of soil improvement as United States Patent (USP) 4015970, it contains the center fixation nuclear of fertilizer, weedicide, and the outside can be surrounded by 15% active substance, and the polyester compound that is no more than total surface weight 10%.Its centronucleus is mainly saltpetre, ammonium phosphate, Lin Suanergai, ammonium sulfate, vitriolate of tartar etc.It is core with nitrogenous fertilizer that Wrapped fertilizer of Zhengzhou Polytechnical College and manufacturing process thereof (application number is 85101008) have proposed a kind of, and phosphate fertilizer is shell, is the novel particle mixed fertilizer of binding agent with nitrogen phosphorus mud.Between core and shell, can there be one by interlayer that potash fertilizer, little fertilizer, agricultural chemicals, plant-growth regulator constituted.But the manufacturing process complexity of these compound manure is difficult for grasping, and agricultural chemicals wraps between core or interlayer, can not give full play to the effect of agricultural chemicals.Therefore, it is simple to be badly in need of a kind of preparation technology of development, can fully improve fertilizer, and the compound manure of agricultural chemicals utilization ratio to reduce the quantity of applying fertilizer, is removed unnecessary consumption, saves the labor force, reduces use cost.
Task of the present invention provides a kind of granulated compound fertilizer that contains agricultural chemicals and various nutrient elements and preparation method thereof.This granular preparation has the characteristic of pesticide granules preparation and granulated compound fertilizer concurrently, and its preparation method can not only shortened process, and can reduce production costs and use cost.
Task of the present invention realizes by following scheme: weight percent is respectively nitrogenous fertilizer 15～21; phosphate fertilizer 10～18%; potash fertilizer 5～6% and needed conditioning agent; after pulverizer was crushed to 80～100 orders, the agricultural chemicals with 0.3～1.5% added mixing machine, mixed and entered tablets press successively; meet by the caking agent that atomizer sprays into utilizing pump of constant delivery type; form graininess under the situation of constantly rolling, particle diameter is 1～6mm, preferentially selects 2～4mm for use.Particle after the shaping enters the oscillatory type moisture eliminator and carries out drying, promptly makes granular preparation through screening, cooling then.Agricultural chemicals composition in the above-mentioned technological process can not add in the batch mixing process yet, and adds in shaping particles, dry screening back, mixes through mixing machine and is distributed in the particle top layer.Add earlier agricultural chemicals or after add agricultural chemicals this mainly determine its process for making according to actual needs.At last the granular preparation packing that makes is sealed up for safekeeping.Wherein raw materials used generally can select for use respectively as follows: nitrogenous fertilizer: urea, ammonium chloride; Phosphate fertilizer: primary ammonium phosphate, Secondary ammonium phosphate, calcium superphosphate; Potash fertilizer: Repone K, saltpetre; Conditioning agent: kaolin, potter's clay, wilkinite.Agricultural chemicals can be selected Insecticides (tech) ﹠ Herbicides (tech), sterilant according to actual needs respectively for use.Make the series product that are used for various objectives.Sometimes in order to play warning, discriminating effect, can also add tinting material and distinguish and contain different pesticide granules preparations.Sterilant commonly used: thiophos microcapsule, Phoxim microcapsule agent, phorate, monocrotophos, furans pellet etc.; Weedicide: Butachlor technical 92, ethachlor, Fu Leling, molinate; Sterilant: derosal, thiophanate methyl, quintozene etc.Used caking agent can adopt the modified polyvinyl formal glue.
Granulated compound fertilizer containing pesticide of the present invention has the characteristic of pesticide granules preparation and granulated compound fertilizer concurrently, helps mechanize and uses, and can save the time and the labor force that apply various fertilizer and agricultural chemicals respectively.Its process for making is simplified, and two technological processs are integrated, and has reduced production cost and use cost.In manufacturing processed, add conditioning agent, can play functions such as improving the favourable granulation of physicochemical condition.Used modified polyvinyl formal glue, manufacturing process is simple, and cost is low, good water solubility is uniformly distributed in inside and outside the particle as caking agent, has not only improved the intensity of granular preparation, also improve its slow releasing function, increased the efficient of plant absorbing, reduced unnecessary loss.The vibrating drier that adopts is to drive the cell body that seals by vsm driving vibrating mechanism to constitute, I type, II type, the III type material grid distributor installed in the cell body, can guarantee that material evenly flows in cell body, streams density is reasonable, promote close contact of wet stock and thermal medium (stack gas or warm air etc.), the raising drying effect.This machine is compared with existing tumble dryer, low cost of manufacture, and the thermo-efficiency height, only need 5～6 minutes time of drying.And tumble dryer manufacturing cost height, thermo-efficiency is low, about 25～30 minutes of time of drying.The manufacturing approach craft of granular preparation of the present invention is simple, and production cost is low, and the granular preparation of making is convenient to mechanize and is used, and both can bring into play the fertilizer effect, can bring into play action of agricultural chemicals again, and increases output, and potion is dual-purpose to be the main characteristic of product of the present invention.
Below in conjunction with drawings and Examples the present invention is further described.
