Description

Technical Field

[0001] This utility model relates to the field of mixing devices, and in particular to a mixing and feeding device for making ecological fertilizer. Background Technology

[0002] Currently, the preparation of organic fertilizers commonly suffers from uneven mixing and poor control of material ratios. Traditional mixing devices often employ single-structure mixing blades, making it difficult to achieve thorough mixing and lacking control over key fermentation parameters. In existing technologies, parameters such as fertilizer pH, temperature, and humidity typically rely on manual detection and adjustment, which is not only inefficient but also fails to ensure the scientific accuracy of fertilizer ratios, particularly regarding the inability to dynamically adjust the carbon-nitrogen ratio based on fertilizer requirements. Furthermore, conventional mixing devices have poor permeability, affecting fermentation quality. To address these shortcomings, there is an urgent need to develop a mobile organic fertilizer mixing and feeding device with monitoring capabilities, adjustable material ratios, and an optimized mixing structure to achieve precise production and improve fertilizer fermentation efficiency and quality. Utility Model Content

[0003] This utility model provides a mixing and feeding device for making ecological fertilizer, which solves the technical problems of uneven mixing, delayed fermentation parameter control, and poor control of carbon-nitrogen ratio in traditional mixing devices.

[0004] In a first aspect, a mixing and feeding device for making ecological fertilizer is provided, comprising: a body, wherein the top of the body is provided with a feed inlet and the bottom of the body is provided with a discharge outlet; a pH sensor for detecting the pH value inside the body; a temperature and humidity sensor for detecting the temperature and humidity inside the body; and a digital display control panel for obtaining the required pH value, temperature and humidity range of the fertilizer, and controlling and adjusting the pH value, temperature and humidity inside the body.

[0005] A stirring mechanism is located inside the main body. The stirring mechanism includes a stirring shaft and spiral stirring blades. One end of the stirring shaft is connected to a drive mechanism, and the spiral stirring blades are spirally arranged on the stirring shaft.

[0006] The spiral stirring blades include conical blades arranged vertically and vertically on the stirring shaft at intervals along the axial direction, and curved blades located between two adjacent conical blades; the surfaces of the conical blades and the curved blades are uniformly arranged with through-holes.

[0007] A drive mechanism, located at the bottom of the body, is used to drive the stirring shaft and rotate the spiral stirring blades.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] This application provides a mixing and feeding device for making ecological fertilizer, which solves the technical problems of uneven mixing, delayed control of fermentation parameters, inaccurate carbon-nitrogen ratio, and inconvenient equipment movement in traditional mixing devices in related technologies.

[0030] like Figure 1 As shown, a mixing and feeding device for making ecological fertilizer is provided, comprising:

[0031] The main body 9 has a feed inlet 10 at its top and a discharge outlet 15 at its bottom.

[0032] pH sensor 12 is used to detect the pH value inside the body 9.

[0033] Temperature and humidity sensor 13 is used to detect the temperature and humidity inside the body 9.

[0034] The pH sensor 12 and the temperature and humidity sensor 13 are both located on the cylinder wall of the main body 9, and can directly contact the material inside the cylinder.

[0035] The digital control panel 14 is used to obtain the required pH, temperature and humidity range of the fertilizer, and to control and adjust the pH, temperature and humidity inside the body 9.

[0036] The stirring mechanism is located inside the body 9. The stirring mechanism includes a stirring shaft 7 and a spiral stirring blade 11. One end of the stirring shaft 7 is connected to the drive mechanism, and the spiral stirring blade 11 is spirally arranged on the stirring shaft 7.

[0037] By setting an inlet 10 at the top and an outlet 15 at the bottom of the main body 9, a complete material inlet and outlet channel is formed, ensuring the continuity of the production process. The configuration of pH sensor 12 and temperature and humidity sensor 13 enables real-time monitoring of key fermentation parameters. Combined with the control function of digital display control panel 14, the fermentation environment conditions can be precisely controlled to ensure fertilizer quality. The stirring mechanism adopts a structure in which stirring shaft 7 drives spiral stirring blades 11. Through a unique spiral arrangement, the mixing uniformity of materials is significantly improved, effectively solving the problem of stirring dead zones in traditional stirring devices. The synergistic effect of these mechanisms together achieves the technical effect of uniform material mixing and precise parameter control in the preparation of ecological fertilizer.

[0038] like Figure 2 As shown, the spiral stirring blade 11 includes conical blades 17 arranged vertically and vertically on the stirring shaft 7 along the axial direction and curved blades 16 located between two adjacent conical blades 17.

[0039] The alternating arrangement of conical blades 17 and curved blades 16 optimizes the traditional circular mixing cross-section into a rectangular mixing surface, increasing the mixing area. The vertical arrangement of the conical blades 17 creates a strong axial shear flow, while the curved blades 16 generate circumferential circulation. The two work together to form a three-dimensional composite flow field. This unique "cone-curved" combination structure endows the device with radial flow properties, ensuring thorough mixing of materials in both the radial and axial directions, and enhancing gas-solid mass transfer. This effectively solves the problems of a single flow field and incomplete mixing found in traditional mixing devices, improving mixing efficiency while reducing energy consumption, achieving a highly efficient and energy-saving mixing effect.

[0040] The conical blade 17 and the curved blade 16 have uniformly arranged through-hole ventilation holes on their surfaces. This design balances agitation and aeration, reducing a certain degree of agitation resistance while ensuring thorough mixing of air and raw materials during the agitation process. Furthermore, a ventilation hole diameter of Φ10mm~Φ30mm yields the best results.

[0041] Ventilation holes of Φ10mm~Φ30mm are evenly arranged on the surfaces of the conical blades 17 and curved blades 16, forming a distributed aeration system that enables dynamic mixing of air and materials during the stirring process. This hole size range ensures sufficient gas flux while maintaining the structural strength of the blades. The special arrangement of the ventilation holes generates a micro-turbulence effect, effectively reducing stirring resistance and improving oxygen mass transfer efficiency. This integrated "stirring-aeration" design overcomes the technical limitations of traditional devices that separate stirring and aeration, resulting in more uniform dissolved oxygen in the materials, significantly improving fermentation efficiency, and achieving energy-saving and high-efficiency production. The optimized design of the ventilation holes allows the stirring device to maintain structural strength while possessing excellent aeration performance and stirring effect.

[0042] like Figure 1 As shown, it includes: a drive mechanism located at the bottom of the body 9, used to drive the stirring shaft 7 and drive the spiral stirring blades 11 to rotate.

[0043] In some embodiments, the discharge port 15 is equipped with a sample detection port for detecting the carbon ratio of the fertilizer after mixing and preparation; the feed port 10 is used for injecting water and adding manure, carbon fertilizer and nitrogen fertilizer, and the amount added is calculated by the digital display control panel based on the detected carbon ratio and the acquired data.

[0044] It should be noted that, although not shown in the figure, those skilled in the art will understand that the manure raw material can be weighed and directly introduced into the feed inlet 10, and water can be directly added by an automatic water valve. Both carbon fertilizer and nitrogen fertilizer are produced using, for example... Figure 1 The automatic fertilizer dispenser 18 shown in the diagram is existing technology. Both the automatic water valve and the automatic fertilizer dispenser 18 are connected to the digital display control panel and are controlled by the digital display control panel to add water and fertilizer, ensuring that the digital display control system can control the amount of fertilizer added based on the detected carbon ratio data and preset parameters.

[0045] The sample detection port at the discharge port 15 allows for real-time carbon ratio detection of the processed fertilizer sample as needed, providing data support for precise control. The built-in NIR sensor directly transmits data to the digital display control panel, providing real-time carbon ratio data. This allows the control panel to calculate and adjust the dosage based on the detected carbon ratio data and preset parameters, ensuring the carbon-nitrogen ratio remains within the optimal range. Of course, the carbon ratio detection method is not limited to this; in other simpler embodiments, manual sampling and data input to the digital display control panel are also possible. This closed-loop control system significantly improves the proportioning accuracy, effectively solving the technical problems of inaccurate manual batching and lagging control in traditional processes, and significantly improving fertilizer quality and production efficiency.

[0046] In some embodiments, the automatic water valve is controlled by the digital display control panel 14 and can also be used to adjust the pH value inside the body 9.

[0047] In some embodiments, an air supply mechanism 5 is included, which is controlled by the digital display control panel 14 to adjust the temperature and humidity inside the body 9. The air supply mechanism can adopt any existing design, which will not be described in detail here.

[0048] By obtaining the required carbon-nitrogen ratio, pH value, temperature, and humidity range of the fertilizer, and controlling and adjusting the carbon-nitrogen ratio of the fertilizer, as well as adjusting the pH value, temperature, and humidity inside the fertilizer, the environmental conditions required for fertilizer fermentation are fully met.

[0049] In some embodiments, the drive mechanism includes a drive motor 4 and a reducer 3, which is prior art and will not be described in detail here.

[0050] In some embodiments, a permeable mesh 6 is included, which is located at the bottom of the body 9 and has evenly distributed ventilation holes. This arrangement further ensures adequate aeration by the stirring device, allowing air and raw materials to mix thoroughly during the stirring process. Furthermore, setting the diameter of the ventilation holes to Φ0.2mm~Φ1mm yields the best results.

[0051] The uniformly arranged microporous structure (Φ0.2mm~Φ1mm) of the breathable mesh 6 forms a three-dimensional aeration system, enabling air to achieve full molecular-level contact with the raw materials during stirring. This microporous design ensures sufficient gas exchange area while avoiding material clogging of the mesh. Working in conjunction with the spiral blades of the stirring mechanism, it forms a dual ventilation mode of "three-dimensional stirring - bottom aeration," significantly improving the dissolved oxygen efficiency of the material. The optimized pore size range ensures uniform airflow distribution, meeting the oxygen requirements of aerobic fermentation while avoiding material leakage caused by excessively large pores. This effectively solves the technical problems of uneven ventilation and insufficient dissolved oxygen in traditional stirring devices, making the fermentation process more thorough and significantly improving fertilizer quality and fermentation efficiency.

[0052] In some embodiments, a traveling mechanism 1 is included, which is used to move the mixing and feeding device to a feeding or storage station.

[0053] In some embodiments, a pusher 8 is included, which is used to facilitate the user to move the mixing and feeding device.
