Description

Technical Field

[0001] This utility model belongs to the field of organic fertilizer production technology, specifically relating to a compounding device for organic fertilizer production. Background Technology

[0002] Organic fertilizer is a carbon-containing material primarily derived from plants and / or animals, applied to the soil to provide nutrients to plants. Processed from biological matter, animal and plant waste, and plant residues, it eliminates toxic and harmful substances and is rich in beneficial substances, including various organic acids, peptides, and abundant nutrients such as nitrogen, phosphorus, and potassium. It not only provides comprehensive nutrition for crops but also has a long-lasting effect, increasing and renewing soil organic matter, promoting microbial reproduction, and improving the soil's physical, chemical, and biological properties. It is a key nutrient source for green food production.

[0003] In the organic fertilizer production process, compounding (or mixing, blending) is a crucial step in ensuring balanced nutrients, diverse functions, and stable quality of the product. Organic fertilizer compounding is divided into pre-fermentation compounding and post-fermentation compounding. Pre-fermentation compounding lays the foundation for fermentation, while post-fermentation compounding determines the quality and function of the final product. The core equipment for compounding is a mixer (or agitator). Common mixers include horizontal twin-shaft paddle mixers, horizontal single-ribbon mixers, vertical spiral mixers, drum mixers, and continuous mixers. Among them, the horizontal twin-shaft paddle mixer has become the mainstream choice for mid-to-high-end organic fertilizer production lines (especially for post-fermentation compounding) due to its excellent mixing performance. However, existing horizontal twin-shaft paddle mixers still have drawbacks such as easy blade wear and inconvenient maintenance. Therefore, there is an urgent need to design a compounding device for organic fertilizer production to solve these problems. Utility Model Content

[0023] This utility model provides, for example Figure 1-5 The compounding device for producing organic fertilizer shown includes:

[0024] A mixing mechanism 100 includes a mixing tank 101. A drive motor 102 is located at one end of the mixing tank 101. Two parallel rotating shafts 103 are located inside the mixing tank 101, with one end of each shaft extending outside the mixing tank 101. Sprockets 104 are mounted on the ends of the rotating shafts 103 and on the output shaft of the drive motor 102. The sprockets 104 are connected by a chain 105. One rotating shaft 103 has a double sprocket mounted on its end, while the other rotating shaft 103 has a single sprocket mounted on its end and on the output shaft of the drive motor 102. When the drive motor 102 is started, the rotating shaft 103 is rotated via the sprockets 104 and the chain 105. Several mounting ports 106 are provided on the rotating shaft 103. Mounting rods 107 are inserted into both ends of the 06. The cross-section of both ends of the mounting rods 107 is an isosceles trapezoid, which facilitates the insertion of the ends of the mounting rods 107 into the mounting openings 106. The corresponding ends of the two mounting rods 107 are fixedly connected by threads or snaps, which can effectively prevent the mounting rods 107 from detaching during the rotation of the rotating shaft 103. The other end of each of the two mounting rods 107 is fixed with a stirring blade 108. The stirring blade 108 rotates with the mounting rods 107 and stirs and mixes the materials. The top of the mixing box 101 is provided with a feed inlet 109 and the bottom is provided with a discharge outlet 110. The two side plates of the mixing box 101 are hinged to the box body. During maintenance, the side plates of the mixing box 101 can be opened to expose the rotating shaft 103, which facilitates the replacement of the stirring blade 108.

[0025] For example, see Figures 1-2As shown, it also includes a metering mechanism 200, which is located on one side of the mixing box 101. The metering mechanism 200 includes a weighing frame 201. The two ends of the weighing frame 201 are respectively provided with a drive roller 202 and a driven roller 203. Several idler rollers 204 are provided between the drive roller 202 and the driven roller 203. The drive roller 202 and the driven roller 203 are connected by a belt 205. A drive motor 206 is provided on one side of the drive roller 202. The drive motor 206 is connected to the drive roller 202 by a coupling. Weighing sensors 207 are provided at the four corners of the bottom of the weighing frame 201. A weighing controller 208 is provided on one side of the weighing frame 201. A speed sensor 209 is provided on the idler roller 204.

[0026] In this technical solution, the material falls onto belt 205 and is transmitted to the weighing sensor 207 via the weighing frame 201. The weighing sensor 207 converts the vertical gravity of the material into a proportional electrical signal, which drives motor 206 to rotate drive roller 202, thereby rotating belt 205. The speed sensor can measure the actual linear speed of belt 205 in real time. Then, the integrator receives both the weight signal and the speed signal simultaneously. The integrator multiplies these two key signals to obtain the instantaneous flow rate and then integrates them to obtain the cumulative weight. This principle is the same as that of an electronic belt scale and falls within the scope of existing technology, so it will not be elaborated here.

[0027] For example, see Figures 1-2 As shown, one end of the weighing frame 201 is correspondingly set to the feed inlet 109, and the horizontal height of one end of the weighing frame 201 is not lower than the horizontal height of the feed inlet 109.

[0028] In this technical solution, it is ensured that the weighed material can be smoothly conveyed to the feed inlet 109 and enter the mixing box 101 through the feed inlet 109.

[0029] For example, see Figures 1-2 As shown, it also includes a conveying mechanism 300, which is disposed on one side of the metering mechanism 200. The conveying mechanism 300 includes a feeding frame 301. The two ends of the feeding frame 301 are respectively provided with a driving roller 302 and a driven roller 303. A plurality of idler rollers 304 are provided between the driving roller 302 and the driven roller 303. The driving roller 302 and the driven roller 303 are connected by a belt 305. A drive motor 306 is provided on one side of the driving roller 302. The drive motor 306 is connected to the driving roller 302 by a coupling.

[0030] In this technical solution, the required materials can be continuously conveyed to the first belt 205 via the second belt 305. When the metering mechanism 200 detects that the amount of material has reached the set value, it controls the third drive motor 306 to rotate in the reverse direction to recover the remaining material on the second belt 305. Then, the above operation is repeated to quantitatively convey multiple materials into the mixing box 101.

[0031] For example, see Figure 1 As shown, one end of the feeding frame 301 is correspondingly set to one end of the weighing frame 201, and the horizontal height of one end of the feeding frame 301 is not lower than the horizontal height of the weighing frame 201.

[0032] In this technical solution, it is ensured that the material on belt 205 can fall onto belt 205.

[0033] For example, see Figures 3-4 As shown, the system also includes a monitoring mechanism 400. The monitoring mechanism 400 includes a light source 401 and a spectral probe 402 mounted on the top of the mixing tank 101, and a control cabinet 403 mounted on one side of the mixing tank 101. The light source 401 and the spectral probe 402 are coupled via an optical fiber 404. The control cabinet 403 houses a spectrometer 405 and an industrial computer 406. The light source 401 is a halogen lamp or LED lamp capable of emitting near-infrared light in the 780-2500nm range. The spectral probe 402 is tilted and positioned on the inner top surface of the mixing tank 101, 10-50cm away from the material surface.

[0034] In this technical solution, the light source 401 emits near-infrared light and transmits it to the spectral probe 402 via optical fiber 404. The spectral probe 402 focuses the light emitted by the light source onto the material surface and collects the reflected / transmitted light signals. Then, the light signals are sent to the spectrometer 405, which converts the light signals into digital spectral data. Finally, the industrial computer 406 analyzes and displays the nutrient content and mixing uniformity in the spectral data. The principle is to utilize the absorption characteristics of hydrogen-containing groups (such as CH, OH, NH) in organic matter for near-infrared light (780-2500nm). Different components have different absorption peak positions and intensities. By establishing a mathematical model (chemometrics) between the spectrum and target parameters (such as moisture, organic matter, nitrogen, phosphorus, and potassium content), quantitative analysis is achieved.

[0035] Working principle: When using this compounding device for organic fertilizer production, firstly, the type and weight of each material are calculated according to the required type and yield of organic fertilizer. Then, the materials are sequentially conveyed to the metering mechanism 200 through the conveying mechanism 300. The metering mechanism 200 weighs the specified weight of material and conveys it into the mixing tank 101. Then, the drive motor 102 is started to drive the rotating shaft 103 to rotate. The rotating shaft drives the stirring blade 108 to rotate together. The stirring blade 108 mixes and stirs the materials in the mixing tank 101. The monitoring mechanism 400 can measure the nutrient content and mixing uniformity of the materials in real time. When the set value is reached, the organic fertilizer is discharged from the discharge port 110. When it is necessary to replace the worn stirring blade 108, open the side plate of the mixing tank 101, then rotate the corresponding mounting rod 107 to remove the mounting rod 107 along with the worn stirring blade 108. Then, the mounting rod 107 with the new stirring blade 108 is reinserted into the mounting port 106 on the rotating shaft 103. The compounding device for organic fertilizer production is advanced in design, compact in structure, and easy to use. By opening several installation ports 106 on the rotating shaft 103, two installation rods 107 with a stirring blade 108 fixed at one end are inserted into the installation ports 106 and connected to each other, which can improve the stability of the installation of the stirring blade 108. When the stirring blade 108 is worn, the installation rod 107 where the worn stirring blade 108 is located is unscrewed from the rotating shaft 103, and then the installation rod 107 with the new stirring blade 108 is inserted back into the rotating shaft 103, so that the worn stirring blade 108 can be replaced quickly, which is convenient for maintenance.

[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.
