Description

Technical Field

[0001] This utility model relates to the field of irrigation and fertilization technology, specifically a microbubble activated bacterial agent irrigation and fertilization machine. Background Technology

[0002] As modern agriculture develops towards high efficiency, greenness, and sustainability, underground drip irrigation or rhizosphere injection probes are often used for irrigation in orchard root zone restoration, continuous cropping obstacle management, or saline-alkali land microbial improvement. By precisely applying water and nutrient solution near the roots, not only is water saved, but the absorption of nutrients by the roots is also ensured.

[0003] However, traditional drip irrigation or sprinkler irrigation systems mainly supply water and nutrients. In areas with long-term high-density planting, soil aeration decreases, which can easily lead to an anaerobic environment and inhibit root respiration. At the same time, conventional drip irrigation is inefficient for the application of probiotics, while microbial agents, as an important means of improving soil microecology, are often applied to the soil in liquid or powder form with water, resulting in unstable actual application effects. In addition, most microbial agent application devices on the market currently lack on-site activation functions. After the dry powder microbial inoculants are directly applied, it is difficult for them to quickly regain their activity, which further reduces their biological efficacy. Based on this, we propose a microbubble-activated microbial agent irrigation and fertilization machine to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a microbubble-activated bacterial agent irrigation and fertilization machine, which solves the problems of insufficient dissolved oxygen and low application efficiency of probiotics in existing irrigation and fertilization equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a microbubble activated bacterial agent irrigation and fertilization machine, comprising a base 1, a raw water tank 2 fixedly installed on the upper side of the base 1, a bubble production module and a probiotic activation module installed on the upper end of the base 1, both sides of the base 1 are equipped with casters, the top of the raw water tank 2 is provided with a water inlet for injecting clean water and nutrients into the raw water tank 2, and the bottom of the raw water tank 2 is equipped with a high-pressure water pump 3 for pressurizing and transporting the mixed water-fertilizer solution; The bubble production module includes a dissolved gas release tank 4 fixedly installed on the base 1 and a dissolved gas tank 5 installed on the upper end of the dissolved gas release tank 4. The output end of the high-pressure water pump 3 is connected to the top of the dissolved gas tank 5 through a pipeline, which is used to input the water fertilizer solution in the raw water tank 2 into the dissolved gas tank 5 under high pressure. An air inlet pipe 6 is provided on the rear side of the upper end of the dissolved gas tank 5. The lower end of the dissolved gas tank 5 is connected to the upper end of the dissolved gas release tank 4 through a control valve. A mixing pipe 7 is installed on the right end of the dissolved gas release tank 4. The probiotic activation module includes an activation reaction tank 8 installed on the upper side of the base 1 and a probiotic storage tank 9 installed on the upper part of the activation reaction tank 8. The lower end of the probiotic storage tank 9 is connected to the activation reaction tank 8 through a metering injection pump. The metering injection pump is used to quantitatively add concentrated probiotic preparation to the activation reaction tank 8. The activation reaction tank 8 is equipped with an activation component. The activation reaction tank 8 is used to rejuvenate the probiotics to restore their metabolic activity. The bottom of the activation reaction tank 8 is connected to a mixing tube 7 through a metering pump. The metering pump is used to quantitatively inject the activated probiotic solution into the mixing tube 7.

[0006] Furthermore, the interior of the dissolved gas tank 5 is equipped with a packing layer, which is made of hydrophilic porous material. The packing layer is used to increase the contact area between the gas and liquid phases. When water and oxygen are injected into the dissolved gas tank 5 simultaneously, the oxygen is fully dissolved in the water under high pressure to form supersaturated dissolved gas water.

[0007] Furthermore, a microporous diffuser 41 is provided on the top of the inner side of the dissolved gas release tank 4. The microporous diffuser 41 and the top of the dissolved gas release tank 4 form a release chamber. The supersaturated dissolved gas water is released into the release chamber under reduced pressure and a large number of microbubbles (with a diameter of 50–300 μm) are instantly precipitated after passing through the microporous diffuser 41.

[0008] Furthermore, a pure oxygen generator is connected to the air intake pipe 6, which is used to inject oxygen-enriched gas into the dissolved gas tank 5.

[0009] Furthermore, the mixing pipe 7 is connected to the bottom of the dissolved air tank 5 via the second water pump 71, and a Venturi mixer 72 is provided at the right end of the mixing pipe 7, and the right end of the Venturi mixer 72 is used to connect to an external irrigation system.

[0010] It should be noted that the dissolved air water containing bubbles, the probiotic liquid, and the nutrient solution are all injected into the mixing tube and mixed under the negative pressure effect of the Venturi mixer 72 before being injected into the irrigation system. The irrigation system uses underground drip irrigation heads or root injection probes at the end of the irrigation pipes to precisely apply microbubble compound liquid carrying probiotics into the crop root zone. When the microbubbles break in the soil pores, they generate local microscale high-pressure shock waves, which disturb the soil structure and promote the penetration of oxygen, nutrients and probiotics into the deeper soil, achieving a triple synergistic effect of oxygen, nutrients and microbial community in the root zone.

[0011] Furthermore, an inlet pipe 81 is provided on the side of the upper end of the activation reaction vessel 8, which is used to connect sterile water.

[0012] Furthermore, the activation assembly includes a heating unit 801 installed on the inner wall of the activation reaction vessel 8, a stirring rod 802 rotatably installed inside the activation reaction vessel 8, and a stirring motor 803 fixedly installed at the front end of the activation reaction vessel 8. The heating unit 801 is used to regulate the temperature inside the activation reaction vessel 8 (preferably 30–37°C). The output end of the stirring motor 803 is connected to the front end of the stirring rod 802. The stirring motor 803 is used to drive the stirring rod 802 to rotate. The surface of the stirring rod 802 is provided with an array of blades. When the stirring rod 802 rotates, it forms a stirring and mass transfer process to enhance the bacterial solution, promote rejuvenation culture, and restore the metabolic activity of probiotics.

[0013] Furthermore, a heating wire is provided in the heating unit 801, and a temperature sensor is provided on the inner wall of the activation reaction vessel 8. The temperature sensor is used to monitor the activation environment temperature in real time and feed it back to the control system.

[0014] It should be noted that the control system is electrically connected to the high-pressure water pump 3, the metering injection pump, the control valve, the temperature controller and various sensors. It can automatically adjust the dissolved air pressure, the amount of bacterial solution added, the mixing time and the irrigation period according to the preset program or external sensor signals, so as to realize the fully automated operation of the process.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This microbubble-activated bacterial agent irrigation and fertilization machine generates microbubbles with a diameter of 50-300μm through a high-pressure dissolution system, which increases the dissolved oxygen in the water to 3-5 times that of conventional irrigation. At the same time, it uses a gas-liquid mixing device to evenly load probiotics onto the surface of the bubbles. When the microbubbles break in the soil, they can form local high-pressure shock waves, which promote the deep penetration of the bacterial agent and achieve a triple synergistic effect of oxygen, nutrients and bacteria in the root zone. 2. This microbubble activated bacterial agent irrigation and fertilization machine has a probiotic storage tank for storing probiotic dry powder or concentrate. When adding, it is revitalized through an activation reaction tank to restore the metabolic activity of probiotics. The large specific surface area of ​​the microbubbles enables uniform adsorption of bacteria, preventing sedimentation and inactivation. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-6This embodiment of a microbubble-activated bacterial agent irrigation and fertilization machine includes a base 1, a raw water tank 2 fixedly installed on the upper side of the base 1, a bubble production module and a probiotic activation module installed on the upper part of the base 1. Both sides of the base 1 are equipped with casters (facilitating flexible movement and positioning of the equipment in different working environments such as greenhouses, orchards, or open fields). The top of the raw water tank 2 has a water inlet for injecting clean water and nutrients into the raw water tank 2 (achieving preliminary mixing of water and fertilizer). A high-pressure water pump 3 is installed at the bottom of the raw water tank 2, used to pressurize the mixed water-fertilizer solution (at a pressure of 0.3–0.6). (MPa pressure) delivery; the bubble production module includes a dissolved air release tank 4 fixedly installed on the base 1 and a dissolved air tank 5 installed on the upper end of the dissolved air release tank 4. The output end of the high-pressure water pump 3 is connected to the top of the dissolved air tank 5 through a pipeline, which is used to input the water-fertilizer solution in the raw water tank 2 into the dissolved air tank 5 under high pressure. An air inlet pipe 6 is provided on the rear side of the upper end of the dissolved air tank 5. The lower end of the dissolved air tank 5 is connected to the upper end of the dissolved air release tank 4 through a control valve (such as a solenoid valve). A mixing pipe 7 is installed on the right end of the dissolved air release tank 4; the probiotic activation module includes an activation reactor installed on the upper side of the base 1. The active container 8 and the probiotic storage tank 9 installed on the upper part of the activation reaction tank 8 are connected at the lower end of the probiotic storage tank 9 to the activation reaction tank 8 via a metering injection pump (which can accurately add compound concentrated bacterial agents such as lactic acid bacteria and Bacillus). The metering injection pump is used to quantitatively add concentrated probiotic preparations to the activation reaction tank 8. The activation reaction tank 8 is equipped with an activation component and is used to rejuvenate and culture probiotics to restore their metabolic activity. The bottom of the activation reaction tank 8 is connected to the mixing pipe 7 via a metering pump. The metering pump is used to quantitatively inject the activated probiotic solution into the mixing pipe 7.

[0020] In this embodiment, a pure oxygen generator is connected to the air inlet pipe 6. The air inlet pipe 6 is used to inject oxygen-enriched gas into the dissolved gas tank 5. Oxygen-enriched gas can be produced on-site, avoiding reliance on external gas cylinders for gas supply, improving the safety and continuity of equipment operation. At the same time, the oxygen-enriched environment significantly enhances the saturation solubility of oxygen in water, providing a guarantee for the subsequent generation of high-concentration microbubbles.

[0021] It should be noted that pure oxygen is used instead of air for dissolved gas because air contains only about 21% oxygen, with the remainder being mainly nitrogen. Nitrogen is not only difficult to dissolve in water, but it may also form large bubbles that escape during decompression release, affecting the stability of microbubbles. Using pure oxygen can maximize the dissolved oxygen level in the water, reduce interference from ineffective gases, and ensure that the microbubble system is mainly composed of oxygen, which is beneficial to the aerobic microbial activity in the root zone and the respiration of crop roots.

[0022] Please see Figure 1 , Figure 2 and Figure 3In this embodiment, the dissolved gas tank 5 is provided with a packing layer inside. The packing layer is made of a hydrophilic porous material (such as ceramic honeycomb, modified polypropylene Pall rings or stainless steel wire mesh). The packing layer is used to increase the contact area between the gas and liquid phases. When clean water and oxygen are injected into the dissolved gas tank 5 at the same time, the oxygen is fully dissolved in the water under high pressure to form supersaturated dissolved gas water.

[0023] It should be noted that the design of the packing layer must balance pressure drop control and mass transfer enhancement. If the packing density is too high, it will lead to increased system resistance and energy consumption; if it is too sparse, the mass transfer effect will be poor. A specific surface area ≥200 m² is preferred. 2 / m 3 Lightweight hydrophilic packing with a porosity of >90% reduces pump power consumption while ensuring efficient gas dissolution. In addition, the hydrophilic treatment of the packing surface helps to distribute the water film evenly and prevents gas short circuits or the formation of local dry areas.

[0024] In this embodiment, a microporous diffuser 41 is provided on the top of the inner side of the dissolved gas release tank 4. The microporous diffuser 41 and the top of the dissolved gas release tank 4 surround each other to form a release chamber. The supersaturated dissolved gas water is released into the release chamber under reduced pressure and a large number of microbubbles are instantly precipitated after passing through the microporous diffuser 41.

[0025] It should be noted that the microporous diffuser 41 is made of sintered ceramic or porous titanium alloy with a pore size range of 20–50 μm. Porous titanium alloy is corrosion-resistant, resistant to biological contamination, and has a long service life, making it more suitable for long-term continuous operation. It also adopts a detachable design, which is convenient for regular cleaning and maintenance. At the same time, the structure of the release chamber should avoid eddy dead corners to ensure uniform bubble generation and prevent excessively high local concentrations from causing bubble aggregation and rupture.

[0026] Please see Figure 1 , Figure 2 , Figure 5 In this embodiment, the mixing pipe 7 is connected to the bottom of the dissolved air tank 5 via the second water pump 71 to form a circulating return channel, so that some of the dissolved air water continues to flow, maintaining the stability and uniformity of microbubbles in the system and preventing bubbles from agglomerating and floating due to stagnation. A Venturi mixer 72 is provided at the right end of the mixing pipe 7 (which uses the negative pressure effect generated by the high-speed water flow to further draw in and homogenize the gas-liquid fluid), and the right end of the Venturi mixer 72 is used to connect to an external irrigation system (such as drip irrigation tape or underground infiltration pipe).

[0027] Please see Figure 1 , Figure 5 , Figure 6In this embodiment, an inlet pipe 81 is provided on the side of the upper end of the activation reaction tank 8. The inlet pipe 81 is used to connect sterile water (or buffer solution). The sterile water is used to adjust the initial concentration and osmotic pressure of the activation system to avoid damage to probiotics caused by high salt or dry environment. The activation components include a heating unit 801 installed on the inner wall of the activation reaction tank 8, a stirring rod 802 rotatably installed inside the activation reaction tank 8, and a stirring motor 803 fixedly installed at the front end of the activation reaction tank 8. The heating unit 801 is used to regulate the temperature inside the activation reaction tank 8 (preferably 30–37°C). The output end of the stirring motor 803 is connected to the front end of the stirring rod 802. The stirring motor 803 is used to drive the stirring rod 802 to rotate. The surface of the stirring rod 802 is provided with an array of blades. When the stirring rod 802 rotates, it forms a stirring and enhanced mass transfer process for the bacterial solution, promotes rejuvenation culture, and restores the metabolic activity of probiotics.

[0028] In this embodiment, a heating wire is provided in the heating unit 801, and a temperature sensor is provided on the inner wall of the activation reaction vessel 8. The temperature signal is fed back to the control system to realize constant temperature closed-loop regulation. At the same time, the control system can automatically start stirring, add bacteria at timed intervals, and record the activation time according to the preset program to ensure that the bacterial community is in a highly active state before each application.

[0029] It should be noted that the activation process of probiotics is a key step in determining their colonization ability in the field. Dry powder probiotics are in a dormant state and recover slowly after being directly applied to the soil, making them susceptible to competition and rejection by native microorganisms. In this embodiment, through on-site temperature-controlled activation, mechanical stirring, and nutrient replenishment, the bacteria can be rejuvenated within 20–60 minutes, restoring the activity of their metabolic enzyme system and significantly improving their survival rate and ecological competitiveness. In addition, the activation tank is made of food-grade stainless steel with a smooth inner wall without dead corners, making it easy to clean and disinfect and preventing cross-contamination.

[0030] The working principle of the above embodiments is as follows: At the start of the operation, the operator injects clean water and nutrients into the raw water tank 2 through the inlet, starts the high-pressure water pump 3, and pressurizes the water-fertilizer solution into the dissolved air tank 5. At the same time, the pure oxygen generator injects oxygen-enriched gas into the dissolved air tank 5 through the air inlet pipe 6. Under the synergistic effect of high pressure and packing layer, oxygen is fully dissolved in water to form supersaturated dissolved air water. After the dissolved air water is depressurized by the control valve, it enters the dissolved air release tank 4, where a large number of micron-sized oxygen microbubbles are instantly released under the action of the microporous diffuser 41. On the other hand, the concentrated bacterial agent in the probiotic storage tank 9 is quantitatively added to the activation reaction tank 8 through a metering injection pump, while sterile water is added through the water inlet pipe 81. Under the combined action of the heating unit 801 and the stirring motor 803, temperature-controlled stirring activation is carried out to restore the probiotics' vigorous metabolic activity. After activation, the active bacterial solution is delivered to the mixing pipe 7 by the bottom metering pump, where it merges with the high dissolved oxygen water rich in microbubbles from the dissolved gas release tank 4. Under the dual mixing action of the second water pump 71 and the Venturi mixer 72, a three-phase stable composite liquid of "oxygen + nutrients + active probiotics" is formed, which is finally delivered to the crop root zone through the irrigation network. When microbubbles seep into soil pores with the water flow, they gradually burst due to collisions and pressure changes, releasing dissolved oxygen and generating localized microscale high-pressure shock waves. This disturbs the soil microstructure, opens blocked channels, and promotes the migration and uniform release of oxygen, nutrients, and beneficial bacteria adsorbed on the bubble surface into deeper soil layers up to 40–60 cm. This achieves simultaneous and synergistic oxygen replenishment, nutrient supply, and beneficial bacteria colonization in the root zone, significantly improving the soil microecological environment, promoting root development, and enhancing crop resistance, yield, and quality.

[0031] It should be noted that the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.
