Description

Technical Field

[0001] This utility model belongs to the field of ecological regulator preparation technology, and in particular relates to a preparation device for a slow-release composite ecological regulator. Background Technology

[0002] Slow-release compound ecological regulators, as important inputs in agricultural ecological regulation and plant growth management in recent years, are widely used in crop cultivation, soil improvement, and ecological restoration due to their advantages such as slow nutrient release, environmental friendliness, and significant comprehensive regulatory effects. The compound ecological regulator uses wood-based activated carbon as a functional carrier, adsorbing acid-base regulators, organic microbial agents, and plant growth promoters into the pores of the activated carbon, and then sealing them with a polyacrylamide solution. Through scientific formulation, it achieves high efficiency, slow release, and multifunctional synergistic effects, effectively and long-lastingly improving the vegetation growth performance of cement-based vegetation spray substrates. The uniformity of material mixing and the stability of additive distribution during the preparation process directly affect the product's functional performance and slow-release effect.

[0003] In existing technologies, the preparation of slow-release composite ecological regulators mostly employs traditional mixing tank structures, supplemented by spraying systems and basic stirring devices to complete the mixing of multi-component materials. However, when dealing with multiphase composite materials such as activated carbon, microbial agents, and liquid regulators, traditional mixing equipment generally suffers from technical bottlenecks such as uneven mixing, inaccurate spraying, low automation levels, and poor ease of operation, making it difficult to meet the industrial-scale preparation requirements of high-performance ecological regulators. Chinese Patent Publication No. CN218774712U discloses a preparation and mixing device for plant growth regulators, including a premixing tank, a plant growth regulator mixing tank, a sampling coil, a fixing plate, and a collection tank. The sampling coil is located on the outside of the plant growth regulator mixing tank, and the premixing tank is located on the top of the mixing tank. The bottom of the mixing tank is connected to a distribution pipe via a liquid guide pipe, and the bottom of the distribution pipe has multiple diverter heads. The fixing plate is located at the top center of a supporting column, and a frame is located at the bottom of the supporting column. Multiple collection tanks are located on the bottom side of the fixing plate, and the collection tanks are positioned directly opposite the diverter heads. This utility model includes a plant growth regulator mixing tank, with a premixing tank on top. A metering tank and a feeding hopper are located on both sides of the top of the premixing tank, facilitating the quantitative addition of the growth regulator. The premixing tank can premix the growth regulator and then discharge it into the mixing tank for further mixing. However, considering the specific preparation requirements of sustained-release composite ecological regulators, existing preparation devices still have the following drawbacks:

[0004] First: The existing preparation equipment has a simple spraying system design, which mainly relies on conventional nozzles to spray liquid raw materials onto the material surface. It lacks effective dispersion control and gas-liquid mixing assistance mechanisms, which leads to uneven local spraying or insufficient blind area coverage of key additives (such as acid-base regulators and functional additives) during the spraying process. This seriously affects the uniformity of additive distribution and reaction effect in the material, and consequently leads to a decrease in the performance stability of the final slow-release product.

[0005] Second: The spraying mechanism and the mixing mechanism lack effective spatial layout and coordination. The spraying process is often independent of the mixing process. The sprayed raw materials cannot fully and timely come into contact with and blend with the base materials in the mixing process. Especially when it comes to composite raw materials with strong adsorption and large particle size differences, such as wood-based activated carbon, the mixing effect is poor and the uniformity of the materials in three-dimensional space is difficult to guarantee, which restricts the stable release of the slow-release system.

[0006] Therefore, there is an urgent need to develop a specialized device that can accurately disperse raw materials, optimize spraying and stirring, and automate the entire process. This device is characterized by low mixing efficiency, uneven spraying and dispersion, poor process flexibility, and a lack of integrated operation capabilities. Utility Model Content

Furthermore, descriptions involving "first," "second," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0033] like Figures 1-4 As shown, an apparatus for preparing a slow-release composite ecological regulator includes:

[0034] The support 1 has a lifting drive device 2 installed on its top. The lifting drive device 2 is a hydraulic cylinder. The drive end of the lifting drive device 2 is equipped with a top cover 3. The top cover 3 is equipped with a stirring mechanism and a spraying mechanism 27.

[0035] The preparation container 4 has an open top and an internal material holding space. The top of the preparation container 4 can be detachably connected to the bottom of the top cover 3 by bolts or the pressing force of the lifting drive device 2. After the top cover 3 and the preparation container 4 are combined, the stirring mechanism can drive the stirring of the material in the holding space, while the spraying mechanism 27 sprays the added raw materials onto the surface of the material.

[0036] When preparing a slow-release composite ecological regulator using this device, firstly, the lifting drive device 2 is activated, the piston rod retracts, and the upper cover 3 is slowly raised. The preparation container 4 moves below the upper cover 3, and the top opening of the preparation container 4 is fully open. At this time, the operator can conveniently put 100 parts of wood-based activated carbon, 0.2 parts of plant growth regulator, 1.5 parts of organic microbial inoculant, and other basic materials into the container space of the preparation container 4 (in this embodiment, this device is used to prepare a slow-release composite ecological regulator and is applied to the stirring process in the whole process). After the addition is completed, the piston rod of the lifting drive device 2 pushes the upper cover 3 to descend smoothly and fit tightly against the top of the preparation container 4. The two are fixed by bolts or firmly connected under the pressure of the hydraulic cylinder.

[0037] Subsequently, during the start-up of the stirring mechanism, the spraying mechanism 27 is activated. The stirring mechanism operates, thoroughly mixing the materials within the space formed by the upper cover 3 and the preparation container 4, ensuring the basic materials are initially and evenly mixed. During this process, the spraying mechanism 27 sprays 12 parts of acid-base regulator onto the material surface. As the stirring mechanism continues to stir, the sprayed additives fully contact and mix with the basic materials, effectively preventing concentrated spraying or uneven mixing. Throughout the process, the upper cover 3 and the preparation container 4 are tightly connected, forming a relatively enclosed space (the two do not need to be completely sealed; an exhaust vent can be opened at the top of the upper cover 3 to facilitate the discharge of incoming gas; the exhaust vent is not shown in the diagram), preventing material splashing and ensuring a safe and clean preparation environment. After stirring is complete, the upper cover 3 is separated from the preparation container 4, and the mixture is then placed in a well-ventilated indoor area to air dry naturally.

[0038] Compared with existing technologies, this device achieves integrated operation of material addition, mixing and raw material spraying through the coordinated operation of lifting drive device 2, top cover 3, stirring mechanism and spraying mechanism 27. Compared with traditional equipment, it greatly improves the material mixing efficiency, ensures that all components are fully and evenly mixed, avoids the problem of uneven mixing that may be caused by manual operation, and also facilitates the movement of preparation container 4, effectively improving the product quality and stability of slow-release composite ecological regulator.

[0039] As a preferred example of this application, the spraying mechanism 27 includes a housing 5 fixedly installed on the inner wall of the top of the upper cover 3. A first pipe 6 is provided inside the housing 5. A second pipe 7 is connected to the side of the first pipe 6 away from the top of the upper cover 3. The first pipe 6 and the second pipe 7 are fixedly connected. An expansion part 8 is provided at the end of the second pipe 7 away from the first pipe 6. A compression block 9 is provided inside the expansion part 8. A raw material dispersion channel 10 is formed between the compression block 9 and the expansion part 8. A nozzle 11 is provided on the side of the housing 5 near the raw material dispersion channel 10. A gas delivery channel 12 is provided between the housing 5 and the first pipe 6 and the second pipe 7.

[0040] This application, through the design of the shell 5, pipes, and compression block 9 in the spraying mechanism 27, utilizes the gas conveying channel 12 to transport gas. Combined with the first pipe 6, the second pipe 7, and the raw material dispersion channel 10, the added raw materials can be evenly dispersed and sprayed onto the material surface through the nozzle 11. Compared to ordinary spraying methods, this structure effectively avoids concentrated or uneven spraying of raw materials, ensuring sufficient contact between additives such as acid-base regulators and the mixture, improving raw material utilization, and resulting in more stable and reliable performance of the final product.

[0041] As a preferred example of this application, the spraying mechanism 27 is provided in two sets, and the output ends of both sets of spraying mechanisms 27 are inclined toward the stirring mechanism.

[0042] This application utilizes two sets of spraying mechanisms 27 operating simultaneously, which can significantly expand the spraying coverage of raw materials. Compared with single-set spraying, it can more quickly and comprehensively distribute additives such as acid-base regulators evenly on the material surface, avoiding spraying blind spots and ensuring that the additives are in more sufficient contact with basic materials such as wood-based activated carbon and plant growth regulators, thereby effectively improving mixing efficiency.

[0043] Secondly, the inclined output end design causes the sprayed raw materials to converge in a cross-shaped manner towards the center of the material, forming a three-dimensional interlaced spray trajectory on the surface of the material. When the stirring mechanism is running, this interlaced distribution of raw materials and materials will produce a stronger convection and diffusion effect, accelerating the penetration of raw materials into the interior of the material, ensuring that each component achieves a more uniform mixture in three-dimensional space, significantly improving the mixing uniformity, and thus ensuring the stability of the performance of the slow-release composite ecological regulator product.

[0044] As a preferred example of this application, the compression block 9 is designed in a conical shape, and a guide ring 13 is integrally formed on the side of the compression block 9 away from the first pipe 6. The compression block 9 forms a raw material dispersion channel 10 between the guide ring 13 and the expansion part 8, and the width of the raw material dispersion channel 10 is smaller than the inner diameter of the second pipe 7.

[0045] The design of the conical compression block 9 and the guide ring 13 further optimizes the structure of the raw material dispersion channel 10, so that the regulator raw material is compressed and guided when passing through the dispersion channel, and can be sprayed out evenly in a finer particle state, increasing the contact area between the raw material and the material, ensuring that the raw materials such as acid and alkali regulators are fully and evenly dispersed in the mixture, and improving the quality and performance of the slow-release composite ecological regulator.

[0046] As a preferred example of this application, a connecting frame 14 is installed at the center of the side of the compression block 9 away from the first pipe 6, and the end of the connecting frame 14 away from the compression block 9 is fixedly connected to the inner wall of the expansion part 8.

[0047] The compression block 9 is fixedly connected to the inner wall of the expansion section 8 via the connecting frame 14, which ensures the stability of the compression block 9 during the spraying process and prevents it from shifting or shaking due to the impact of liquid and gas. This ensures the structural stability of the raw material dispersion channel 10, thereby maintaining a stable spraying effect and ensuring that the raw materials sprayed each time can be evenly dispersed to the material surface, thus guaranteeing the consistency of the product preparation process and the stability of product quality.

[0048] As a preferred example of this application, it also includes a raw material storage container 15, which is connected to a flexible liquid delivery pipe 17 via a pump 16. The other end of the liquid delivery pipe 17 is connected to the end of the first pipe 6 away from the second pipe 7. The liquid delivery pipe 17 has two output ends, which are respectively connected to two sets of spraying mechanisms 27. Solenoid valves 18 can be set on the two output ends to control the entry of liquid.

[0049] This application incorporates a combination design of a raw material storage container 15, a pump 16, and a liquid delivery pipe 17. The raw material storage container 15 is typically designed as a corrosion-resistant liquid storage tank with a sealed cap, capable of storing liquids such as acid-base regulators and additives. It works in conjunction with the pump 16 (which can be a diaphragm pump, peristaltic pump, or micro gear pump) to achieve quantitative and stable delivery. The flexible liquid delivery pipe 17 is made of highly flexible plastic or composite rubber, with good corrosion resistance and pressure resistance. The two output ends are connected to the first pipe 6 of the two spraying mechanisms 27 using a threaded quick-connect snap-fit ​​connection structure, ensuring multi-point synchronous liquid supply. The liquid delivery pipe 17 can be equipped with a solenoid valve 18 to achieve independent on / off control, providing a stable and controllable raw material supply system for the spraying mechanism 27 and improving the automation level of the preparation process.

[0050] As a preferred example of this application, it also includes an air delivery device 19, which can be a blower or an air compressor. The output end of the air delivery device 19 is connected to a flexible gas delivery pipe 20. The other end of the gas delivery pipe 20 is connected to the gas delivery channel 12 through the side of the housing 5 away from the nozzle 11. The gas delivery pipe 20 has two output ends, which are connected to two housings 5 ​​respectively. Solenoid valves 18 can be installed on the two output ends to control the entry of gas.

[0051] The air delivery device 19 and the gas delivery pipe 20 provide a stable gas power source for the spraying mechanism 27. The pressure generated by the air delivery device 19 propels the gas through the gas delivery pipe 20 to the gas delivery channel 12, creating a gas-liquid mixture spray effect in conjunction with the flow of the regulator, further enhancing the dispersion and uniformity of the raw materials. In the example of this application, the gas delivery pipe 20 is made of pressure-resistant, corrosion-resistant hose or composite material, and its end directly passes through the interface provided at the top of the housing 5 to connect with the gas delivery channel 12, forming a stable, sealed gas delivery passage. This connection is generally fixed using a threaded, flanged, or snap-fit ​​structure to ensure no leakage during the delivery process.

[0052] As a preferred example of this application, the stirring mechanism includes a rotary motor 21 installed on one side of the upper cover 3. The drive end of the rotary motor 21 is equipped with a rotating shaft 22 via a coupling. A plurality of spaced stirring rod assemblies 23 are installed on the outer side of the rotating shaft 22. The other end of the rotating shaft 22 is rotatably connected to the inside of the upper cover 3 away from the rotary motor 21 via a bearing. The position of the housing 5 is offset from the position of the stirring rod assembly 23.

[0053] The mixing mechanism employs a design where a rotary motor 21 drives a rotating shaft 22 and a mixing rod assembly 23. Combined with the staggered arrangement of the housing 5 and the mixing rod assembly 23, this achieves synergistic optimization of mixing and spraying functions. The rotary motor 21 provides stable power, driving the mixing rod assembly 23 to thoroughly mix the materials, resulting in more uniform mixing of basic materials such as wood-based activated carbon, plant growth regulators, and organic microbial agents. The staggered arrangement of the housing 5 and the mixing rod assembly 23 avoids interference with the spraying mechanism 27 during mixing, ensuring that the sprayed additives directly act on the materials being mixed.

[0054] As a preferred example of this application, the bottom of the preparation container 4 is equipped with self-locking casters 24;

[0055] The preparation container 4 is equipped with casters 24 at the bottom, which significantly improves the ease of movement of the equipment. After the materials are mixed, the preparation container 4 can be easily moved to a well-ventilated indoor area for natural air drying using the casters 24, avoiding material spillage or container collision damage that may occur during manual handling.

[0056] As a preferred example of this application, the top of the cover 3 is provided with a first arc-shaped portion 25, and the bottom of the preparation container 4 is provided with a second arc-shaped portion 26;

[0057] The design of the top cover 3 with a first arc-shaped part 25 and the bottom of the preparation container 4 with a second arc-shaped part 26 optimizes the overall structure of the equipment and the material flow characteristics. The spraying mechanism 27 is installed on the first arc-shaped part 25, so that the spraying mechanism 27 can directly form an inclination on the first arc-shaped part 25. The second arc-shaped part 26 forms a guide structure at the bottom of the preparation container 4. The design of the discharge pipe and valve (not shown in the figure) can be added to the bottom of the second arc-shaped part 26, so that the raw materials can be directly discharged after the preparation is completed.

[0058] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
