Description

Technical Field

[0001] This application relates to the technical field of organic fertilizer mixing and adding equipment, specifically to a device for adding micro-nano mineral materials during the fermentation of biological organic fertilizer. Background Technology

[0002] In modern agriculture, fertilizer is an indispensable nutrient for plant growth. Among them, organic fertilizer is favored by farmers for its natural and environmentally friendly characteristics. However, with the development of agricultural technology, a new type of fertilizer has emerged—organic fertilizer with added minerals.

[0003] Organic fertilizer with added minerals, as the name suggests, is a fertilizer made by mixing natural minerals with organic fertilizers. This type of fertilizer not only contains the organic matter, nitrogen, phosphorus, potassium, and other nutrients found in organic fertilizers, but also adds various natural mineral components, such as trace elements like calcium, magnesium, sulfur, iron, and zinc. These mineral elements play a crucial role in plant growth, compensating for deficiencies in soil nutrients and improving plant disease resistance and yield.

[0004] Organic fertilizers with added minerals combine the advantages of both organic and mineral fertilizers, providing plants with comprehensive and balanced nutrition. This type of fertilizer not only meets the plant's need for organic matter but also replenishes the soil with mineral elements, improving soil fertility.

[0005] Organic fertilizers with added minerals can improve soil structure and enhance soil aeration and water retention. At the same time, the organic matter in these fertilizers can also promote the reproduction and activity of soil microorganisms, further improving the soil environment.

[0006] Because organic fertilizers with added minerals can provide plants with comprehensive nutritional support, plants using this type of fertilizer tend to grow vigorously, have strong disease resistance, high yields, and excellent quality.

[0007] Organic fertilizers with added minerals are made from natural minerals and organic matter, and do not contain harmful chemicals or pollutants such as heavy metals. Therefore, the use of this type of fertilizer not only does not pollute the environment, but also promotes the sustainable development of agricultural production.

[0008] Micro- and nano-mineral materials are materials processed to the micro- and nano-scale, meaning that the particle size of these mineral materials has any one dimension in three-dimensional space ranging from 1 to 100 nanometers. After modification, micro- and nano-mineral materials can be used as mineral fertilizers in agriculture. For example, a study by the Chinese Academy of Agricultural Sciences, "The Effects of Spraying Different Nanomaterials on Rice Seedling Growth and Phosphorus Absorption," showed that the combined treatment of nano-hydroxyapatite and potassium chloride can promote rice seedling growth and increase the phosphorus content of rice seedlings. Related scientific literature, such as "Research Progress on the Application of Different Nanomaterials in Nanofertilizers," reviews the application of nano-carbon, nano-metals and metal oxides, and nano-minerals in nanofertilizers and their effects on crop growth, pointing out the broad prospects of nanofertilizers.

[0009] However, in actual production, because the particle size of micro-nano mineral materials is at the micro-nano scale, they are much smaller than existing mineral fertilizer particles and are more prone to floating. Therefore, how to incorporate micro-nano mineral materials into organic fertilizers is a problem that needs to be solved. Utility Model Content

[0010] In view of this, this application provides a device for adding micro-nano mineral materials during the fermentation of bio-organic fertilizer. It is used in conjunction with an organic fertilizer turning machine or a compost turner. Micro-nano mineral materials can be added during the turning process of organic fertilizer. Through multiple turnings of the organic fertilizer, the micro-nano mineral materials can be evenly mixed with the organic fertilizer to form organic fertilizer with added minerals.

[0011] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0012] A device for adding micro / nano mineral materials during the fermentation of bio-organic fertilizer includes a frame, a hopper, material pipes, a sandblasting head, an air compressor, an air source distributor, an air pipe, and an electric heating device. The hopper and air compressor are fixedly mounted on the frame, which has a cantilever. A horizontal bar is suspended from the cantilever, and several sandblasting heads are equidistantly arranged on the horizontal bar. Several material pipes are connected to the bottom of the hopper, and each material pipe is connected to a sandblasting head. The air compressor is located next to the hopper, and its outlet is connected to the air source distributor. The air source distributor distributes multiple branch outlets, the number of which is greater than or equal to the number of material pipes. One end of each air pipe is connected to one of the branch outlets on the air source distributor, and the other end is connected to a sandblasting head. An electric heating device is installed on the sandblasting head.

[0013] Furthermore, the top opening of the hopper is provided with a hopper cover.

[0014] Furthermore, a stirring shaft is provided inside the hopper, and stirring blades are provided on the stirring shaft.

[0015] Furthermore, a stirring shaft drive motor is provided on the side of the hopper, which is connected to the stirring shaft to drive the stirring shaft to rotate and stir.

[0016] Furthermore, an air storage tank is provided between the air compressor and the air source distributor.

[0017] Furthermore, an oil-water filter is installed before the gas source distributor.

[0018] Furthermore, the electric heating device includes an outer heat insulation sleeve and an electric heating wire. The electric heating wire is spirally wound around the inner wall of the outer heat insulation sleeve. The outer heat insulation sleeve is provided with fastening screws. The electric heating device is fitted onto the sandblasting head. There is a gap between the electric heating wire and the sandblasting head to prevent the electric heating wire from contacting the sandblasting head. The electric heating device is fastened to the sandblasting head by fastening screws.

[0019] Furthermore, the heating wire is a low-voltage heating wire, with a voltage not exceeding 36V, for safety reasons.

[0020] Furthermore, the sandblasting head is also equipped with a thermocouple or a resistance thermometer for controlling the temperature of the electric heating device.

[0021] Furthermore, the frame is also equipped with a dust suppression spray device, the nozzle of which is higher than the sandblasting head.

[0022] This invention relates to a device for adding micro-nano mineral materials during the fermentation of biological organic fertilizer, which needs to be used in conjunction with an organic fertilizer fermentation turning machine or an organic fertilizer fermentation turning and composting machine.

[0023] This utility model relates to a device for adding micro-nano mineral materials during the fermentation of biological organic fertilizer. When using this device, it needs to be installed on an organic fertilizer fermentation turning machine or an organic fertilizer fermentation turning and threshing machine, with the spray nozzle facing the direction of turning and threshing the organic fertilizer.

[0024] This invention relates to a device for adding micro-nano mineral materials during the fermentation of biological organic fertilizer. The working principle is as follows: Micro-nano mineral materials are added to the hopper. During the organic fertilizer fermentation turning and turning operation, an air compressor is activated, and high-pressure air carrying the micro-nano mineral materials is sprayed out from the sandblasting heads, forming a fan-shaped sandblasting surface. Several sandblasting heads mounted on crossbars can cover the entire width of the organic fertilizer tank. During the turning process, the micro-nano mineral materials are evenly sprayed, combining with the moisture evaporated from the organic fertilizer during turning, condensing, and then settling into the organic fertilizer. Since the organic fertilizer needs to be turned multiple times during fermentation, and the micro-nano mineral materials are added after multiple turnings, the micro-nano mineral materials are evenly distributed in the organic fertilizer, forming mineral-enriched organic fertilizer.

[0025] The beneficial effects of this utility model are as follows:

[0026] 1. This utility model relates to a device for adding micro-nano mineral materials during the fermentation of biological organic fertilizer. During the process of turning organic fertilizer with an organic fertilizer fermentation turning machine or an organic fertilizer fermentation turning machine, micro-nano mineral materials are evenly sprayed into the organic fertilizer through sandblasting. By adding micro-nano mineral materials multiple times during the fermentation process, the micro-nano mineral materials can be evenly dispersed in the organic fertilizer.

[0027] 2. This utility model relates to a device for adding micro-nano mineral materials during the fermentation of biological organic fertilizer. Since the fermentation of organic fertilizer is in a humid state, the air humidity is high during the turning process. Due to their small particle size and large specific surface area, micro-nano mineral materials easily absorb moisture from the air and clump together on the sandblasting head, thus clogging it. By installing an electric heating device on the sandblasting head, the phenomenon of micro-nano mineral materials clumping together with moisture in the air is eliminated, ensuring smooth sandblasting.

[0028] 3. The device for adding micro-nano mineral materials during the fermentation of biological organic fertilizer of this utility model has a stirring shaft in the hopper, which is also used to break up the clumps of micro-nano mineral materials in the hopper, so that the material can be fed smoothly and avoid clogging the feed pipe.

This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0034] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0035] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0036] Bio-organic fertilizer is an organic fertilizer made from organic waste as raw material and microorganisms as biological transformation medium through certain processing.

[0037] The fermentation of bio-organic fertilizer is mainly achieved through the metabolic activities of microorganisms. Organic waste is mixed with microorganisms and fermented under specific conditions of temperature, humidity, and oxygen. During this process, microorganisms break down organic matter into smaller molecules, such as proteins, carbohydrates, and fats, while simultaneously producing organic matter and microbial metabolites. These organic matter and microbial metabolites are the nutrients in the fertilizer, such as nitrogen, phosphorus, potassium, and calcium.

[0038] Turning the compost pile is essential during the fermentation process of bio-organic fertilizer, mainly for the following reasons:

[0039] First, turning the pile can make the fermentation of the material more uniform, and turning the pile can also break up the material.

[0040] Secondly, turning the compost pile can provide sufficient oxygen inside, preventing the material from being in an anaerobic state.

[0041] Currently, composting processes generally advocate high-temperature aerobic fermentation. If the compost is anaerobic, it will produce an unpleasant ammonia odor, polluting the environment, harming the health of operators, and also causing nitrogen loss. Turning the compost can prevent anaerobic fermentation inside the compost.

[0042] Third, turning the pile allows the moisture inside the material to dissipate, accelerating the evaporation of moisture.

[0043] Fourth, turning the compost pile can lower the material temperature: When the internal temperature of the compost pile exceeds 70℃, most of the medium- and low-temperature microorganisms in the compost will be killed if it is not turned. Most importantly, such a high temperature will accelerate the decomposition of the material, greatly increasing material loss. Therefore, a temperature above 70℃ is detrimental to composting. Generally, the compost temperature should be controlled at around 60℃, and turning the pile is an effective measure to lower the temperature.

[0044] Fifth, turning the pile can accelerate the decomposition of materials: if the turning is well controlled, the decomposition of materials can be accelerated, which can greatly shorten the fermentation time.

[0045] During the turning process of bio-organic fertilizer, the humidity of the surrounding air is extremely high due to the release of internal moisture. Measurements show that, regardless of the weather conditions, the air humidity about 1 meter above the turned pile exceeds 92%.

[0046] Example 1:

[0047] Please refer to Figure 1 , Figure 2 and Figure 3 This embodiment describes a device for adding micro-nano mineral materials during the fermentation of bio-organic fertilizer. It is used in conjunction with an organic fertilizer turning machine with a width of 3.5 meters. The 3.5-meter-wide organic fertilizer turning machine can be a wheeled turning machine, a tracked turning machine, or a mixed turning machine.

[0048] A device for adding micro-nano mineral materials during the fermentation of bio-organic fertilizer includes a frame 1, a hopper 2, a material pipe 3, a sandblasting head 4, an air compressor 5, an air source distributor 6, an air pipe 7, and an electric heating device 8. The frame 1 is 3.9 meters long. The hopper 2 and the air compressor 5 are fixedly mounted on the frame 1. The frame 1 has a cantilever 11, on which a crossbar 12 is suspended. Five sandblasting heads 4 are evenly spaced on the crossbar 12. The hopper 2 is a long hopper with a rectangular upper section and a trapezoidal lower section in cross-section. The top opening is equipped with a liftable hopper cover 21. A stirring shaft 22 is installed inside the hopper 2. The stirring shaft 22 is equipped with stirring blades. A stirring shaft drive motor is installed on the side of the hopper 2 and connected to the stirring shaft 22 to drive the stirring shaft 22 to rotate and stir. Five material pipes 3 are equidistantly connected to the bottom of the hopper 2, with a spacing of 0.6 meters between each material pipe 3. Each material pipe 3 is connected to a sandblasting head 4. The air compressor 5 is located next to the hopper 2. The air outlet of the air compressor 5 is connected to an air source distributor 6. The air source distributor 6 distributes five air outlets. One end of the air pipe 7 is connected to one of the air outlets on the air source distributor 6, and the other end is connected to a sandblasting head 4. An electric heating device 8 is provided on the sandblasting head 4.

[0049] The electric heating device 8 includes an outer heat insulation sleeve 81 and an electric heating wire 83. The electric heating wire 83 is spirally wound on the inner wall of the outer heat insulation sleeve 81. The outer heat insulation sleeve 81 is provided with fastening screws 82. Two sets of fastening screws 82 are arranged in a circumferentially evenly distributed manner. The electric heating device 8 is sleeved on the sandblasting head 4. There is a gap between the electric heating wire 83 and the sandblasting head 4. The gap distance is greater than 5mm to avoid contact between the electric heating wire 83 and the sandblasting head 4. The electric heating device 8 is fastened to the sandblasting head by the fastening screws 82.

[0050] The sandblasting head 4 is also equipped with a thermocouple 41, which is a bonded thermocouple, used to control the temperature of the electric heating device 8. During operation, the electric heating device 8 heats the sandblasting head 4 to between 70-90°C, making the sandblasting head a high-temperature source. This prevents moisture in the air from condensing and clumping with the micro-nano mineral materials at the sandblasting head 4, thus avoiding blockage.

[0051] Example 2:

[0052] This embodiment is an improvement on the first embodiment, adding a gas storage tank with a volume of 0.2 cubic meters. An oil-gas separator is installed at the gas outlet of the gas storage tank, and the gas storage tank is located between the air compressor 5 and the air source distributor 6.

[0053] This improvement stabilizes the pressure of the high-pressure gas, thus making the sprayed micro- and nano-mineral materials more uniform and stable.

[0054] Example 3:

[0055] This embodiment adds a dust suppression spray device, the nozzle of which is higher than the sandblasting head.

[0056] Because micro- and nano-sized mineral materials are sprayed through a sandblasting nozzle and float in the air as dust, most of these materials will combine with moisture in the air and settle onto the organic fertilizer within a short time. However, in some cases, such as when the organic fertilizer is too dry, insufficient moisture is released during the turning process, or the weather is too dry, some smaller micro- and nano-sized mineral materials can remain suspended in the air for a long time, causing pollution. With the addition of a dust-suppressing spray device, these floating micro- and nano-sized mineral materials will collide and combine with the micro-droplets, thus quickly settling onto the organic fertilizer. The dust-suppressing spray device also increases the moisture content of the organic fertilizer, which is more conducive to its fermentation.

[0057] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
