Abstract
The present invention provides a sustained and controlled fertilizer releasing constant temperature quick nutrient extracting instrument. The present invention comprises a constant temperature water tank, a sample extracting cup, a stainless steel sample mesh bag, a silicon controlled rectifier temperature controller, a temperature patrol instrument, an electric heater, a shell body, heat insulating material and so on. Pure water is used as medium in the constant temperature tank. The silicon controlled rectifier temperature controller is used for realizing the accurate control of the temperature. The upper body of the extracting cup is a rotary squeezing lid with a silica gel mat, which can effectively avoid the evaporation loss of water extract. The present invention solves the technical problem of nutrient releasing ratio quick extracting of the sustained and controlled release fertilizer at high water temperature in particular to in the 100 DEG C situation. The operation is simple and an accurate testing result can be obtained. The present invention is suitable for quickly testing the nutrient releasing ratio of the sustained and controlled release fertilizer and the online quality detection of sustained and controlled release fertilizer manufacturers.
Description
(1) invention field
The instrument of constant temperature quick nutrient lixiviate when the present invention relates to sustained-controll-release fertiliser nutrient release rate assay.
(2) background technology
The nutrient release rate of sustained-controll-release fertiliser is that the key of judging its quality is measured project.At present, the main controlled-release fertilizer production producer in the U.S., Japan, Israel and Europe all be under constant temperature to the lixiviate in water of controlled release fertilizer, then leaching liquor is measured.For usually adopting the method that improves the lixiviate water temperature, its release rate of fast measuring carries out.What often adopt at present is with putting into constant incubator or thermostatic drying chamber after the extraction flask sealing.If but temperature is brought up to 100 ℃, aqueous leaching solution will be seethed with excitement, evaporation etc., cause the result that measures after the lixiviate and the true release rate of nutrient to occur than large deviation.The nutrient that the method that chemurgy scholar association of U.S. official (AOAC) adopts the circulation constant flow pump to connect chromatogram leaching post and 60 ℃ of continuous drip washing of water-bath is carried out release and release control fertilizer extracts, but this device is installed comparatively complicated loaded down with trivial details, cost an arm and a leg, temperature with water-bath control leaching post needs the long period to reach design temperature, and keep the difficult grasp of constant temperature, used plastic tube is easy to wear out under higher temperature, and is difficult to be implemented in the quick lixiviate under 100 ℃ of temperature.
(3) summary of the invention
The purpose of this invention is to provide a kind of can be under the constant temperature of arbitrary temp between the room temperature to 100 ℃, the sustained-controll-release fertiliser nutrient is discharged the instrument that carries out lixiviate, solution is in the technical matters that improves aqueous solution evaporate under the temperature conditions, boiling and nitrogen nutrient loss, since this device can be automatic accurate the control temperature, and have stainless steel lixiviate cup, stainless steel sample mesh bag and a high temperature resistant bleeder valve, make the nutrient leaching process become both simple and easy to do, the result again accurately and reliably.
The technical scheme of sustained-controll-release fertiliser constant temperature quick nutrient leaching instrument of the present invention: this is the extracting at constant temperature instrument of medium with the pure water, it has an attemperater, the stainless steel electric heating tube is arranged, by the constant temperature of controllable silicon temperature controller in the water tank by temperature control sensor control water liquid.Built-in 1 to 20 the lixiviate cup that volume is 350ml of water tank, the mesh bag splendid attire sustained-controll-release fertiliser sample that has stainless (steel) wire to make in the lixiviate cup.Temperature control sensor probe all is housed in each lixiviate cup, shows accurately that by temperature polling instrument the temperature of solution in the cup, controllable silicon temperature controller can make the water temperature in the water tank be controlled at the steady temperature of design temperature ± 1 ℃.
This leaching instrument is different with the method for lixiviate in the past both at home and abroad, after release and release control fertilizer sample and 200ml distilled water are joined the lixiviate cup, can reach the temperature of setting in a short period of time, and constant be in ℃ scope of design temperature ± 1.When extraction temperature is brought up to 100 ℃, silica gel sealing pad on the lixiviate bowl cover will bear the vapor pressure of about 0.03MPa, making the interior solution of cup constant is 100 ℃ ± 1 ℃, stainless steel mesh bag in the cup makes the putamina of controlled release fertilizer be unlikely to stop up tap hole when emitting leaching liquor or sticks on the wall of cup, reduced the trouble of cleaning.Leaching liquor is directly put into volumetric flask by tap hole, has reduced lixiviate cup, the complicated processes of bottle when volumetric flask shifts in the past, has reduced the vaporization loss and the error that produce in the leaching process.
