Problems solved by technology

However, most of the water storage materials made of water-absorbent resin are in the form of flocs and powders, and the specific gravity is also very light. If the water storage materials are directly applied in the field, it will consume a lot of human resources, which is very uneconomical and effective. poor method
[0004] Use existing fertilizer granules and water-absorbent resin materials to manufacture water-storage fertilizers. Because the water-storage materials themselves are light in specific gravity and are flocculent elastomers, they cannot be combined with fertilizer granules to form new products.
Therefore there is no report about the water storage fertilizer

Embodiment 1

[0035] Mix 20kg of urea, 20kg of monoammonium phosphate, 15kg of potassium chloride and 40kg of clay in the pre-processor and add them to the outer bucket of the single-screw extruder. After the water storage material is mixed evenly in the pre-mixer, it is added to the inner hopper of the single-screw extruder. At an extrusion temperature of 70°C, the mixture is extruded into strips with an inner core diameter of 1mm and an extruded product with a length of 5mm. After cutting, it becomes a 5×5×5mm cube-shaped granular water storage fertilizer, which is passed through a drum dryer. And drum cooler, after drying and cooling, it will be screened by vibrating screen, and it will be water storage fertilizer after packaging.

Embodiment 2

[0037] Mix 53kg of urea, 15kg of ammonium bicarbonate, 2.0kg of magnesium sulfate, 0.05kg of ferrous sulfate, 0.02kg of zinc sulfate, 0.03kg of boric acid, 0.01kg of acid blue pigment, and 29.89kg of zeolite powder into the single screw skewer The outer bucket of the extruder. After the water storage material is mixed evenly in the pre-mixer, it is added to the inner hopper of the single-screw extruder. Under the extrusion temperature of 55°C, extrude the mixture into a sheet with an inner core thickness of 2mm and an extrudate with a thickness of 5mm and a width of 15mm. After cutting, it becomes a 15×15×2.5mm sheet of water storage fertilizer, which is dried in a fluidized bed. After being dried and cooled by machine and drum cooler, it is screened and packaged by a vibrating screen to become a blue water-storage fertilizer.

Embodiment 3

[0039] Mix 20kg of urea, 9.79kg of ammonium chloride, 40kg of ammonium sulfate, 0.1kg of urease inhibitor, 0.1kg of nitrification inhibitor, 0.01kg of acid red, and 30kg of attapulgite into the single-screw extruder after mixing evenly in the preprocessor outside the fight. After the water storage material is mixed evenly in the pre-mixer, it is added to the inner hopper of the single-screw extruder. At an extrusion temperature of 65°C, the mixture is extruded into a triangular strip with an inner core diameter of 2mm and an 8mm outer side length, which is cut into 8×8×8mm cubic triangular block granular water storage fertilizer and dried by a drum Drying machine and fluidized bed cooler, after drying and cooling, it will be screened by a vibrating screen, and it will be red water storage fertilizer after packaging.

Abstract

The invention discloses a method for manufacturing a water storage fertilizer, which comprises the following steps of: mixing fertilizers for producing the water storage fertilizer, filler and other raw materials in a treatment device according to a proportion, and preparing the water storage materials into a water storage material mixture; and adding the mixture into a sandwich extruder, extruding the mixture into a sandwich extruded substance of multiple shapes at a certain temperature under certain pressure, cutting the extruded substance into granules, and drying, cooling and screening the granules to obtain a finished product. The invention belongs to a novel manufacturing process for the water storage fertilizer and a novel product.

Description

technical field [0001] The invention relates to agricultural water storage materials and fertilizers, in particular to a manufacturing method and product of a novel water storage fertilizer. Background technique [0002] Various fertilizers are widely used in agricultural production, mainly elemental fertilizers such as urea, ammonium sulfate, potassium chloride, heavy calcium, etc., and multi-component compound fertilizers containing nitrogen, phosphorus, potassium and other nutrients. They are all granular fertilizers made through certain processes and equipment. They can provide various nutrients for plant growth. It has also contributed to the increase in production and income of farmers. But the growth of plants is inseparable from sunlight and water in addition to fertilizer nutrients. Especially in arid areas with little precipitation, it is not news to us that crops have been greatly reduced or lost due to lack of water. If we can provide fertilizer nutrients for ...
