Description

Technical Field

[0001] This utility model relates to the field of amino acid water-soluble fertilizer production technology, and in particular to an amino acid water-soluble fertilizer fine mixing equipment. Background Technology

[0002] Amino acid water-soluble fertilizer is a functional water-soluble fertilizer. It is made of free amino acids as the main component, with appropriate amounts of calcium or trace elements such as copper, iron, manganese, zinc, boron, and molybdenum added in proportions suitable for plant growth. It can be either liquid or solid. In today's agricultural field, with the rapid development of technology, the requirements for fertilizer quality and production efficiency are becoming increasingly stringent. Amino acid water-soluble fertilizer is highly favored in the cultivation of various crops due to its excellent absorption and rapid effects, and market demand continues to rise.

[0003] A published patent: An environmentally friendly mixing device for the production of amino acid aqueous fertilizer (publication number: CN214764804U), which includes a main body, a mixing mechanism and an air suction mechanism. The mixing mechanism includes a mixing rod assembly, which is divided into a first mixing rod and a second mixing rod. The first mixing rod includes a plug part, and the plug part has a groove formed inward on its outer circumference. This application has the effect of enabling the mixing rod assembly to be installed quickly.

[0004] The aforementioned patents have the following drawbacks: They lack an automatic weighing structure for the injection material, and all injection is controlled manually, making it difficult to achieve precise and uniform mixing of various raw materials. This can easily lead to unstable fertilizer product quality and affect the consistency of fertilizer efficacy. During the mixing process, due to the differences in the characteristics of the materials, clumping and agglomeration can easily occur, hindering the mixing process and reducing production efficiency.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, various raw materials are first injected into the weighing tube through the feed pipe. The weighing sensor can detect the mass of the raw materials inside the weighing tube. When the mass inside the weighing tube meets the required mass for the proportion, the injection of raw materials into the weighing tube is stopped. Then, the third solenoid valve is opened, allowing the raw materials inside the weighing tube to enter the mixing tank through the discharge pipe. The weighing sensor can detect the mass of the raw materials injected into the mixing tank, thereby controlling the precise proportion of raw materials.

[0021] 2. In this utility model, the resistance received by the stirring arm can be detected by the torque sensor. If the torque sensor detects that the resistance received by the stirring arm has increased, it indicates that clumps have formed at the bottom of the tank. Then, the crushing motor drives the crushing blade to rotate and break up the clumps. When the torque sensor detects that the resistance received by the stirring arm has decreased and become stable, it indicates that the raw materials clumped at the bottom of the mixing tank have been broken up, thereby ensuring that the mixing process is not affected by the clumping problem.

[0022] 3. In this invention, a heat insulation layer is provided inside the outer shell of the mixing tank. The heat insulation layer is made of high-efficiency heat insulation material. The temperature inside the mixing tank is detected by a first temperature sensor. If the temperature is too high, the second solenoid valves on the first and second hot water pipes are closed, and the second solenoid valves corresponding to the second and first cold water pipes are opened. The first water pump transports cool water from the cold water tank through the first cold water pipe from the inlet pipe to the temperature control pipe, and then flows back into the cold water tank through the outlet pipe along the second cold water pipe. If the first temperature sensor detects that the temperature inside the mixing tank is too low, the second solenoid valves on the first and second cold water pipes are closed. Open the second solenoid valves on the first and second hot water pipes. The first cold water pipe transports hot water from the hot water tank inside the first hot water pipe to the temperature control pipe through the inlet pipe, and then flows back into the hot water tank through the outlet pipe along the second hot water pipe. If the first temperature sensor detects that the temperature inside the mixing tank is suitable, close all the second solenoid valves. The above structure can accurately maintain the material inside the mixing tank in a suitable constant temperature range, avoiding the increase in material viscosity and the decrease in fluidity due to excessively low temperature, which would affect the mixing effect. It also prevents excessively high temperature from causing denaturation and inactivation of heat-sensitive components such as amino acids, effectively ensuring that the material properties remain stable as before.

[0035] Working principle: A collection bucket is placed below the discharge pipe 16. The sealing cap 44 is unscrewed, and cold water is injected into the cold water tank 41 and hot water tank 42 through the water injection pipe 43. The water in the hot water tank 42 is heated through the first hot water pipe 422. The water temperature inside the hot water tank 42 is detected by the second temperature sensor 425. Various raw materials are injected into the weighing pipe 55 through the feed pipe 53. The mass of the raw materials inside the weighing pipe 55 is detected by the weighing sensor 54. When the mass inside the weighing pipe 55 meets the required proportion, the injection of raw materials into the weighing pipe 55 is stopped, and the third solenoid valve 57 is opened, allowing the raw materials inside the weighing pipe 55 to enter the mixing tank 11 through the discharge pipe 56. The weighing sensor 54 detects the injection into the mixing tank. The quality of the raw materials inside the tank is controlled to ensure precise proportions. The stirring motor 61 drives the electric stirring shaft 63, which in turn rotates the torque sensor 64 and the stirring drum 65. The stirring arm 641 performs deep and fine mixing of the materials near the tank wall and bottom, ensuring no dead corners or accumulations, achieving thorough and uniform mixing. The torque sensor 64 drives the stirring arm 641, which in turn drives the stirring blades 651 in the stirring drum 65. The stirring blades 651 powerfully propel the materials through a wide-range, high-speed circulation within the tank, allowing for rapid dispersion and initial mixing. The torque sensor 64 detects the torque applied to the stirring arm 641. If the torque sensor 64 detects an increase in resistance to the stirring arm 641, the crushing motor 661 drives the crushing blade 662 to rotate, breaking up the agglomerated raw materials and ensuring that the mixing process is not affected by agglomeration. The mixing tank 11 has an internal insulation layer 12 to keep it warm. During mixing, the first temperature sensor 18 detects the internal temperature of the mixing tank 11. If the temperature is too high, the second solenoid valves 45 on the first hot water pipe 422 and the second hot water pipe 423 are closed, while the second solenoid valves 45 corresponding to the second cold water pipe 413 and the first cold water pipe 412 are opened. The first water pump 411 transports cool water from the cold water tank 41 through the inlet pipe 14 to the temperature control tank via the first cold water pipe 412. The water flows from the outlet pipe 15 through the second cold water pipe 413 back into the cold water tank 41. If the first temperature sensor 18 detects that the temperature inside the mixing tank 11 is too low, the second solenoid valves 45 on the first cold water pipe 412 and the second cold water pipe 413 are closed, and the second solenoid valves 45 on the first hot water pipe 422 and the second hot water pipe 423 are opened. The hot water inside the hot water tank 42 is transported from the inlet pipe 14 through the first cold water pipe 412 to the temperature control pipe 13, and flows from the outlet pipe 15 through the second hot water pipe 423 back into the hot water tank 42. If the first temperature sensor 18 detects that the temperature inside the mixing tank 11 is suitable, all the second solenoid valves 45 are closed. After mixing is complete, the first solenoid valve 17 is opened.The mixed raw materials fall from the discharge pipe 16 into the collection bucket, thus completing one mixing cycle.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
