A urine tank is connected to a feed inlet of the first evaporation heat recycling section via a pipeline provided with a urine pump, a first evaporation separator is arranged at the upper end of the first evaporation heat recycling section, an outlet end of the first evaporation separator is connected to an inlet end of the second evaporation heater via a pipeline, a second evaporation separator is disposed at the upper end of the second evaporation heater, an outlet of the second evaporation separator is connected to the top end of the granulation tower via a pipeline, and the inlet of the second evaporation heater is externally connected with a dispensing tank via a feeding pipeline. The preparation device is added with the dispensing tank for slow-release urea synergistic agent and additive, utilization rate and manurial effect of produced fertilizer are evidently improved, and the problem of fertilization in agricultural production is solved.
Description
Technical field
The utility model relates to the equipment field of chemical fertilizer, specifically is a kind of preparation facilities of long-acting slow-release fertilizer.
Background technology
As everyone knows, China's vast rural area chemical fertilizer in use can be had only 30% by what crop effectively utilized, remaining 70% since a variety of causes run off in vain or caused waste by soil fixing, the fertilizer efficiency time length is also very short, in order to supply the nutrient of loss, the peasant have to strengthen rate of fertilizer application, yet, Shi Deyue is many, runs off also just manyly more; The nitrogenous fertilizer that runs off and remain in invalid phosphorus potash fertilizer in the soil and cause agricultural land soil to harden and the pollution of environment, make the effect that refertilizes continue to descend, and Soil structure is because the influence of fertilising has been caused the increase of disease and pest further to influence the quality and yield of crop by artificial destruction; In each chemical fertilizer that runs off major part is being rained and during pouring but also can be flushed away not only, has caused secondary pollution to form the vicious cycle of fertilising, pollution.
The utility model content
The purpose of this utility model provides a kind of preparation facilities of long-acting slow-release fertilizer, has increased the dosing vessel of slow-release carbamide synergistic agent and additive, and chemical fertilizer utilization ratio of producing and fertilizer efficiency time obviously improve, and has solved the problem of fertilization in the agriculture production.
The technical solution of the utility model is as follows:
A kind of preparation facilities of long-acting slow-release fertilizer, include urine flash tank, one section evaporation heat energy recovery zone, two-section evaporating heater, prilling tower, the feed opening of described urine flash tank is connected with discharge pipe, discharge pipe is divided into two, wherein one is connected with urine tank, and another is connected to the opening for feed of one section evaporation heat energy recovery zone; The opening for feed of the pipe connection to of described urine tank by the urine pump is housed section evaporation heat energy recovery zone, the discharge port of one section evaporation heat energy recovery zone connects one section vapor seperator, the exit end of one section vapor seperator is by the entrance end of pipe connection to two-section evaporating heater, the two-section evaporating heater discharge port is connected with the dual circulation separator, the pipe connection of the exit end of dual circulation separator by the urea melting pump is housed is to the top of prilling tower, it is characterized in that: the entrance end of described two-section evaporating heater dosing vessel by the feed pipe connection outward, be provided with stirrer in the dosing vessel, in the feed pipeline feeding pump be installed.
Described feeding pump is a volume pump.
Described stirrer includes agitating vane, stir shaft, agitator motor.
The utility model has increased the dosing vessel of slow-release carbamide synergistic agent and additive, add 2.5～3.0kg slow-release carbamide synergistic agent by urea per ton, the ratio that slow-release carbamide synergistic agent per ton is joined 12～14kg left and right sides additive is configured, and fertile utilization ratio of the long-acting slow-release of preparing and fertilizer efficiency time obviously improve.This long-acting slow-release fertilizer has the following advantages: (1) long-acting slow-release fertilizer is a kind of novel pervasive, efficient, release rate is slow, utilization ratio is high agricultural fertilizer; (2) production method is a chemical method, by with urine chemosynthesis long-acting slow-release fertilizer; (3) synergistic agent is a kind of novel plant nutrition promotor, have advantage natural, broad-spectrum high efficacy, this fertilizer can be degraded fully by biology, does not have any residual, agricultural-food and environment are had tangible security, are a kind of nontoxic, harmless, noresidue, the environment-friendly product of degraded fully; (4) be applicable to all kinds of plants and soil, the nutritive element that can need plant has extremely strong chelating function, and energy enriched in nitrogen, phosphorus, potassium concentrate trace element for the plant absorbing utilization; (5) can promote root growth, improve the resistance of crop, promote proteinic synthesizing, improve quality, utilization rate of fertilizer improves about 30%; (6) can make nutrient slowly-released, farm crop not take off not early ageing of fertilizer; (7) effect of performance fertilizer nutrition promotor and soil conditioner improves soil physical and chemical property, is of value to the farmland quality construction; (8) need the rule of nutrient definitely identical with crop, time of releasing, length was directly proportional with nutrient content concentration in the soil, the fertilizer synergistic in time of releasing length and the fertilizer, the obvious effect of increasing production of farm crop; (9) amount is made in raising, realizes food safety, is the forward position of fertilizer science and technology.
