Detailed implementation manners

[0030] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] In the description of the present invention, it should be understood that the meaning of "a plurality of" is two or more unless otherwise specifically defined.

[0032] Please refer to Figure 9 , the present invention provides a production mixing and dissolving method for a slow-release ternary full-effect high-concentration liquid fertilizer, including the following steps.

[0033] S1: Add specified raw materials and water into a dissolving device for water dissolution to make a turbid liquid with a specified ratio.

[0034] Specifically, at normal temperature and pressure, add water into the set mixing and dissolving device, and then add the raw material, chemical fertilizer-grade ammonium phosphate, to make a 50% turbid liquid, and control the time until the ammonium phosphate is completely dissolved into a suspension.

[0035] The raw material ammonium phosphate used in this process can also be fertilizer-grade diammonium phosphate or monoammonium phosphate, which depends on the demand for phosphorus in the final product;

[0036] If the final product requires high nitrogen, some nitrogen-containing fertilizers can be added, such as ammonium nitrate, urea, ammonium polyphosphate, etc.

[0037] S2: Add the specified chelating agent to the above turbid liquid to obtain the corresponding clear liquid.

[0038] Specifically, the specified raw materials are fertilizer-grade monoammonium phosphate, diammonium phosphate, triple superphosphate, ordinary superphosphate, calcium magnesium phosphate fertilizer, etc. produced by wet-process phosphoric acid, and the specified chelating agent is the chelating agent produced by Yunnan Leadford Technology Co., Ltd. Add 50% potassium phosphate chelating agent to the above turbid liquid. Through chelation, the solid insoluble substances (such as Ca, Mg, Si, S, Fe, Zn, etc.) contained in the turbid liquid are chelated into water-soluble complexes, and the complexes will be the medium and trace nutrient components in the final product. The usage amount of the chelating agent accounts for 65-75% of the raw material weight, depending on the solid water-insoluble substances in the raw material.

[0039] Potassium phosphate chelating agent has extremely high complexing ability for alkali metal ions. The dosage of phosphate chelating agent makes the suspension reach the requirement range of 3.0-5.0% of GB water-insoluble substances for the clear liquid. The clear liquid contains potassium polyphosphate, and it takes 10-30 days for potassium polyphosphate to hydrolyze into phosphate radicals, forming the slow-release property of the final product.

[0040] S3: Adjust the pH value of the above clear liquid so that the pH value of the adjusted clear liquid in a 1.0% aqueous solution ranges from 1.5 to 2.3.

[0041] Specifically, add acid to the above clear liquid to adjust the pH value of the clear liquid to 1.5-2.0 (1.0% aqueous solution);

[0042] The acid can be nitric acid, sulfuric acid and citric acid. If nitric acid is used, the final product is nitro liquid fertilizer. If sulfuric acid is used, the final product is sulfur-based liquid fertilizer. The added acid can be one kind of acid or a mixed acid of multiple acids;

[0043] At the same time, citric acid can also be added. Citric acid is an organic acid, which can adjust the soil pH value for plants, promote the growth of plant roots, enhance the resistance of plants, and promote photosynthesis.

[0044] S4: Add alkali solution to the clear liquid after the pH value adjustment is completed for neutralization to obtain a neutralized liquid with a pH between 6 and 7. This neutralized liquid is the ternary full-effect slow-release liquid fertilizer with the specified concentration.

[0045] Specifically, slowly pour the prepared 50% potassium hydroxide / potassium carbonate solution into the clarified liquid for neutralization. The amount of the alkali solution is such that the pH of the neutralized liquid is controlled between 6 and 7. The neutralized liquid with a pH between 6 and 7 is a 50% concentration ternary all-effective slow-release liquid fertilizer.

[0046] The liquid fertilizer has a low pH value and a high P2O5 content; the liquid fertilizer has a high pH value and a high K2O content. In this process, the N component is a fixed value, and the change in the pH value plays a role in adjusting the P:K ratio of the liquid fertilizer.

[0047] Furthermore, to reduce costs, chemical fertilizer-grade phosphoric acid is used, and a phosphate chelating agent is used to complex the 14 - 16% solid insoluble substances (such as Ca, Mg, Si, S, Fe, Zn, etc.) contained in chemical fertilizer ammonium phosphate. Then, nitric acid or sulfuric acid is added to lower the pH value, and then potassium hydroxide or potassium carbonate, and potassium nitrate or potassium sulfate are added, and neutralized to 6 - 7. A series of liquids with N = 50 - 150 mg / l, P2O5 = 200 - 650 mg / l, and K2O = 200 - 550 mg / l can be obtained. Adjust the concentration of the liquid, add a certain amount of neutral ammonium polyphosphate and potassium polyphosphate to form the slow-release property of the liquid fertilizer, and finally the obtained mixed liquid forms a high-concentration liquid fertilizer with a slow-release nitrogen + phosphorus + potassium + TE content greater than or equal to 600 ml / L.

[0048] Furthermore, Specific Example 1:

[0049] 40 g of chemical fertilizer-grade diammonium phosphate is dissolved in 80 ml of water, melted and stirred to form a suspension. 26 g of a chelating agent is added to the suspension and stirred until it becomes clear. 20 g of nitric acid with a concentration of 65% is added to the clear liquid. At this time, the pH of the clear liquid is 2.25. 40 g of potassium hydroxide is made into a 50% aqueous solution and gradually added to the clear liquid, and stirred to form a relatively concentrated 150 ml liquid fertilizer. This is a nitro low-nitrogen high-phosphorus potassium slow-release all-effective liquid fertilizer. The final analysis results are: pH = 6.8, N:P:K+TE = 80:650:550 (mg / l), TE = Ca, Mg, Si, S, Fe, Zn, etc., and the water-insoluble substances ≤ 1.0%;

[0050] The obtained nitro low-nitrogen high-phosphorus potassium all-effective liquid fertilizer is suitable for calcium-loving plants growing on calcareous soils with a relatively high pH value, such as corn and most vegetables, and economic crops such as cotton, tobacco, and fruit trees; Specific Example 2:

[0052] Based on the same amount of clarified liquid obtained in Example 1, 20 g of sulfuric acid with a concentration of 65% is added to the clarified liquid. At this time, the pH of the clarified liquid is 2.15. 47 g of potassium hydroxide is made into a 50% aqueous solution and gradually added to the clarified liquid while stirring. 5 g of ammonium polyphosphate is added during stirring, and finally a relatively concentrated 150 ml liquid fertilizer is formed. This is a sulfur-based medium-nitrogen, high-phosphorus, potassium-release, slow-release, and all-effect liquid fertilizer. The final analysis results are: pH = 6.8, N:P:K = 100:600:600 (mg / l), TE = Ca, Mg, Si, S, Fe, Zn, etc., and the water-insoluble matter is ≤ 1.0%; the obtained product is a sulfur-based low-nitrogen, high-phosphorus, potassium-all-effect liquid fertilizer, which is suitable for basal fertilizers, topdressing fertilizers, seed fertilizers, and topdressing of various soils and various types of crops. Specific Example 3:

[0054] 60 g of chemical fertilizer-grade diammonium phosphate is dissolved in 80 ml of water, melted and stirred to form a suspension. 30 g of potassium phosphate chelating agent is added to the suspension, melted and stirred until it becomes clear. 15 g of sulfuric acid, 10 g of nitric acid, and 6 g of citric acid are added to the clarified liquid. The concentration of sulfuric acid is 65%, the content of citric acid is 98%, and the concentration of nitric acid is 65%. At this time, the pH of the clarified liquid is 1.93. 50 g of potassium hydroxide is made into a 50% aqueous solution and gradually added to the clarified liquid while stirring. 5 g of ammonium polyphosphate is added during stirring, and finally a relatively concentrated 180 ml liquid fertilizer is formed. This is an organic nitro-sulfur-based low-nitrogen, high-potassium, phosphorus-release, all-effect liquid fertilizer. The final analysis results are: pH = 6.8, N:P:K = 70:600:650 (mg / l), TE = Ca, Mg, Si, S, Fe, Zn, etc., and the water-insoluble matter is ≤ 1.0%;

[0055] The organic nitro-sulfur-based low-nitrogen, high-potassium, phosphorus-release, all-effect liquid fertilizer combines the advantages of nitro-sulfur-based fertilizers, adapts to various soils and crops, and has strong drought resistance, disease resistance, and cold resistance, and can improve the photosynthesis efficiency.

[0056] Further, please refer to Figures 2 to 8 A production mixing and dissolving device for a slow-release ternary all-effect high-concentration liquid fertilizer, which is applied to the production mixing and dissolving method of the slow-release ternary all-effect high-concentration liquid fertilizer, includes a mixing tank 101, a feeding mechanism 102, and a discharge valve 103. The feeding mechanism 102 is installed on the top of the mixing tank 101, and the discharge valve 103 is installed at the bottom of the mixing tank 101. It also includes a mixing component;

[0057] The mixing component includes an outer ring rotating gear ring 104, an outer ring stirring frame 105, a driving gear 106, a driving motor 107, and an inner ring stirring member. The outer ring rotating gear ring 104 is rotatably installed in the mixing tank 101. The outer ring stirring frame 105 is fixedly installed on the outer ring rotating gear ring 104.

The output shaft of the driving motor 107 is connected to the driving gear 106, and the driving motor 107 is fixedly installed on one side of the mixing tank 101. The inner ring stirring member is connected to the mixing tank 101 and is used to cooperate with the outer ring stirring frame 105 to more thoroughly and evenly stir and mix the mixed solution inside the mixing tank 101.

[0058] Further, the inner ring stirring member includes an inner ring rotating gear ring 201, an inner ring stirring frame 202, a driving gear 203, and a driving motor 204.

The driving gear 106 and the driven gear 203 are respectively driven by the driving motor 107 and the driven motor 204. When the driving motor 107 and the driven motor 204 respectively drive the driving gear 106 and the driven gear 203 to rotate, the outer ring rotating gear ring 104 and the inner ring rotating gear ring 201 can drive the corresponding outer ring stirring frame 105 and the inner ring stirring frame 202 to rotate, so as to stir the mixed liquid in the mixing tank 101 in different directions. During actual stirring, since the outer ring rotating gear ring 104 and the inner ring rotating gear ring 201 are respectively driven by two independent motors, users can adjust the rotation direction and rotation speed of the outer ring stirring frame 105 and the inner ring stirring frame 202 respectively according to the actual stirring situation, so as to complete the mixing process of the mixed liquid in the mixing tank 101 more quickly and evenly.

The output end of the air pump 501 is communicated with the air inlet of the jet ring frame 503 through the air duct 502. The main body of the jet ring frame 503 is an annular frame, and a plurality of air outlet nozzles are arranged inside the annular frame, so that the user can introduce the gas into the jet ring frame 503 through the air duct 502 by the air pump 501, and then introduce the gas into the monitoring area of the mounting housing 302 through the jet ring frame 503.

After the mixed liquid enters the interior of the installation shell 302, the control motor 403 will cooperate with the control screw 402 to drive the opening and closing carriage 401 to move downward rapidly. Then, the monitoring probe 303 will detect the mixed liquid inside the installation shell 302. After the monitoring of the mixed solution is completed, the air pump 501 will inflate. The gas enters the jet ring frame 503 through the air duct 502. Then, since the jet ring frame 503 fills the gas into the installation shell 302, the liquid inside the installation shell 302 will be discharged through the one-way discharge valve 504 at this time. Moreover, blowing air towards the monitoring probe 303 through the jet ring frame 503 can also blow off the residual mixed liquid on the monitoring probe 303, so that after the monitoring height of the insertion frame 301 is adjusted subsequently, the monitoring probe 303 inside the installation shell 302 can more accurately detect the mixed solution at a specified depth, avoiding interference when detecting mixed solutions at different depths, and facilitating the operator to more accurately judge the mixing condition of the mixed solution inside the mixing tank 101.
