Description

Technical Field

[0001] This utility model belongs to the technical field of agricultural automated production equipment, and in particular relates to a large-scale liquid fertilizer synergist pretreatment and addition equipment. Background Technology

[0002] In large-scale (over 500 mu) agricultural production, adding synergists to liquid fertilizers is crucial for improving fertilizer utilization. However, synergists come in a wide variety of types and differ significantly in practical applications, mainly in the following aspects: diverse physical forms (liquid concentrate, soluble powder, high-concentration solution, etc.); extremely wide dosage ranges (from less than 0.1 kg / mu to over 2 kg / mu); and the need for continuous addition to large-scale operations exceeding 500 mu in a single application. Therefore, large-scale agricultural production places higher demands on the synergist addition process.

[0003] The core contradictions faced by existing synergist addition equipment and processes are mainly reflected in the following aspects: the addition form is singular, which cannot be compatible with such a wide range of dosages and product form differences; powdered synergists are directly added into the reactor, resulting in incomplete dissolution and increasing the risk of pipeline blockage. This contradiction directly leads to three major pain points: (1) fluctuations in metering accuracy, making it impossible to achieve precise addition of synergists; (2) limited production efficiency, which drags down the overall process in large-scale agricultural production; (3) decreased operational safety and stability, which easily leads to various safety and quality problems.

[0004] Therefore, there is an urgent need for an additive equipment that can build a demand-based, graded, and precisely adapted additive process chain through systematic improvement and process upgrades, so as to achieve precise, efficient, and stable addition of additives in large-scale production and support the standardization and quality improvement goals of agricultural production.

When a component is considered to be "connected" to another component, it can be directly connected to the other component or may have an intervening component present.

[0035] The technical solution of this utility model is illustrated below through specific embodiments. It should be understood that the one or more steps mentioned in this utility model do not preclude the existence of other methods and steps before or after the combined steps, or that other methods and steps may be inserted between these explicitly mentioned steps. It should also be understood that these examples are for illustrative purposes only and are not intended to limit the scope of this utility model. Unless otherwise stated, the numbering of each method step is only for the purpose of identifying each method step, and not for limiting the order of each method or defining the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantial changes to the technical content, can also be considered as within the scope of implementation of this utility model.

[0036] The raw materials and instruments used in the examples are not subject to any specific restrictions on their source; they can be purchased from the market or prepared according to conventional methods known to those skilled in the art.

[0037] Please refer to Figures 1-3 The contents shown are for better understanding of the specific structure of this utility model. A large-scale liquid fertilizer synergist pretreatment and addition device, such as... Figures 1-2 As shown, it includes:

[0038] The micro prefabrication unit 1, including a micro storage tank 101, is configured for the pretreatment of a small dose of synergist;

[0039] Medium-sized prefabrication unit 2, including medium-sized storage tank 201, is configured as a pretreatment unit for medium-dose synergists;

[0040] The large prefabricated unit 3, including a large storage tank 301, is configured as a pretreatment for a large dose of synergist;

[0041] The feeding unit 4 is connected to the medium-sized liquid storage tank 201 and the large liquid storage tank 301 respectively, and is configured to inject liquid enhancer into the medium-sized liquid storage tank 201 and the large liquid storage tank 301;

[0042] Adding unit 5 connects the micro liquid storage tank 101, the medium liquid storage tank 201 and the large liquid storage tank 301 to the reaction vessel respectively, and is configured to add synergists to the liquid fertilizer in the reaction vessel.

[0043] The control unit (not shown in the figure) is electrically connected to the micro liquid storage tank 101, the medium liquid storage tank 201, the large liquid storage tank 301, the feeding unit 4 and the adding unit 5, respectively, and is configured to control the operation of the equipment.

[0044] It should be noted that existing synergist addition equipment is usually only equipped with one type of equipment (with a processing capacity of up to ten cubic meters). For small doses (0.1 kg / acre) of synergist, this will result in a waste of equipment resources and the presence of residues in the container, leading to inaccurate measurement.

[0045] This invention features storage tanks of various specifications, which can handle different dosages of synergist separately, enabling unified implementation and precise control, improving production efficiency and avoiding common problems in existing technologies.

[0046] It should be noted that synergists come in various forms: liquid, powder, and concentrate. Current technology involves directly adding powder and concentrate into the reactor and mixing them with the liquid fertilizer. However, this method can easily lead to insufficient dissolution of powdered synergists, causing blockages in the reactor pipes, and can result in incorrect dilution ratios for concentrates, affecting the quality of the finished liquid fertilizer.

[0047] This invention features a micro pretreatment unit, which allows for the pretreatment of powdered or concentrated synergists by dissolving or diluting them in batches within a micro storage tank 101. This prepares a uniformly diluted liquid before it enters the reactor to mix with liquid fertilizer, or it enters a medium-sized storage tank 201 or a large storage tank 301 for proportion adjustment before entering the reactor. This avoids the aforementioned problems.

[0048] It should be noted that the miniature liquid storage tank 101, the medium-sized liquid storage tank 201, and the large liquid storage tank 301 can all preferably be made of plastic in a barrel shape, which can effectively save costs.

[0049] It should be noted that the control unit can be set separately outside or inside the equipment. It preferably includes a PLC (PLC is the abbreviation for Programmable Logic Controller), or it can be a circuit including at least one processor, or a circuit including at least one microcontroller, or it can be a combination of multiple circuits or chips, as long as it can achieve the corresponding function. It is understood that for those skilled in the art, the control circuit can also be a common circuit composed of amplifiers, comparators, transistors, MOSFETs, etc., to implement the corresponding function in a purely hardware manner.

[0050] In practical implementation, a pre-processing unit is set up to pre-treat powdered and concentrated synergists by adding production water to the storage tank of the pre-processing unit for dissolution and dilution. This prevents insufficient dissolution of powder from clogging the reactor pipeline or causes quality problems with the added liquid fertilizer due to uncertain dilution ratios. Setting up large, medium, and small pre-processing units allows for separate processing of large, medium, and small doses of synergists, avoiding the use of large equipment for adding small doses and thus avoiding equipment occupation and reduced production efficiency. The setup of a feeding unit 4, an addition unit 5, and a control unit allows for automatic... The delivery of liquid synergist is controlled, and the liquid flow rate can be controlled together with the flow metering device and the control unit to achieve precise control and prevent metering fluctuations from affecting the synergist effect. A micro pretreatment unit is set up to pre-treat the powder or concentrated synergist in batches in the micro storage tank 101 to dissolve or dilute it in advance, so as to prepare a uniformly diluted liquid before entering the reactor to mix with the liquid fertilizer, or enter the medium storage tank 201 or the large storage tank 301 for proportion adjustment before entering the reactor. This prevents the reactor from being blocked due to insufficient dissolution or the quality of the finished liquid fertilizer from being caused by incorrect dilution ratio.

[0052] It should be noted that the water storage tank 601 is preferably made of plastic and has a barrel-shaped structure, which can effectively save costs by holding the production water inside; the water pump 602 is preferably the structure of the electric water pump 602 in the prior art, but other forms can also be used, which is not limited here; the first flow metering device 603 is preferably the flow meter in the prior art, and the specific type can be selected according to the actual design requirements, which is not limited here.

[0053] It should be noted that the water storage tank 601 stores production water, and the water pump 602 supplies water to the miniature liquid storage tank 101. The first flow metering device 603 measures the flow rate and provides data to the control unit. After the set flow rate is reached, the control unit sends a stop command to the water pump 602 to complete the water supply.

[0054] In practice, water supply unit 6 can supply production water to micro prefabricated unit 1, and the water supply can be controlled by flow meter and control unit, which provides favorable conditions for the refined management of agricultural production.

The stirring drive unit 7 is electrically connected to the control unit, and its power output end is connected to the power input end of the stirring transmission unit 8; the power output end of the stirring transmission unit 8 is connected to the stirring unit 9.

The stirring unit 9 preferably uses a fan blade structure, and is located inside its respective storage tank, and is connected to the power output end of the stirring transmission unit 8.

[0057] In practice, the micro prefabricated unit 1, the medium prefabricated unit 2 and the large prefabricated unit 3 are equipped with a stirring unit 9, which can stir the solution in the storage tank under the control of the control unit, thereby accelerating dissolution and making the solution uniform, thus improving the production efficiency for large-scale agricultural production.

[0058] In the embodiments provided by this utility model, such as Figures 1-2 As shown, the adding unit 5 includes a first liquid delivery device 501 electrically connected to the control unit; the inlet of the first liquid delivery device 501 is connected to the outlet of the micro storage tank 101, and the outlet is connected to the inlet of the reaction vessel. The outlet of the first liquid delivery device 501 is also connected to the inlets of the medium-sized storage tank 201 and the large storage tank 301, respectively.

[0059] The adding unit 5 includes a second liquid conveying device 502 and a second flow metering device 504 electrically connected to the control unit; the inlet of the second liquid conveying device 502 is connected to the outlet of the medium-sized storage tank 201, and the outlet is connected to the reaction vessel; the second flow metering device 504 is installed on the pipeline between the medium-sized storage tank 201 and the reaction vessel.

[0062] It should be noted that the second flow metering device 504 and the third flow metering device 505 are preferably flow meters in the prior art. The specific type can be selected according to the actual design requirements, and no limitation is made here.

[0063] It should be noted that the miniature liquid storage tank 101 can selectively transport the internal solution to the reaction vessel, the medium-sized liquid storage tank 201 and the large liquid storage tank 301 through the first liquid conveying device 501 and pipelines.

[0064] It should be noted that the miniature liquid storage tank 101 is small in size, and precise quantitative measurement can be achieved through the first flow metering device 603 of the water supply unit 6. Therefore, it is not necessary to install a flow metering device at the liquid outlet. It is only necessary to transport all the internal solution to the corresponding component.

[0065] In practice, by setting up a liquid delivery device and a flow metering device that are electrically connected to the control unit, the amount of synergist solution delivered can be precisely and automatically controlled, thus providing favorable conditions for the refinement and automation of large-scale agricultural production.

The fourth flow metering device 402 preferably adopts the flow meter in the prior art. The specific type can be selected according to the actual design requirements, and it is not limited here.

[0069] In practice, the feeding unit 4 and the control unit together achieve precise control of the liquid synergist feeding, providing favorable conditions for the detailed management of large-scale agricultural production.
