Description

Technical Field

[0001] The present invention relates to the technical field of fertilizer processing equipment, and particularly to a device for uniformly adding functional bacteria to liquid biological organic fertilizer. Background Art

[0002] Liquid biological organic fertilizer is a new type of high-efficiency organic fertilizer and plays an important role in agricultural production. It mainly uses organic wastes such as livestock and poultry manure, crop straws, and agricultural and sideline product processing wastes as raw materials, and is made through a series of processes such as microbial fermentation. In this process, beneficial microorganisms multiply in large numbers and play a key role. These microorganisms can decompose macromolecular substances in organic materials and convert them into small-molecule nutrient components that are more easily absorbed by plants, such as amino acids, humic acids, and small-molecule sugars, thus significantly improving the utilization rate of fertilizers.

[0003] However, traditional functional bacteria adding devices have many drawbacks. Some biological organic fertilizers and functional bacteria themselves have high viscosity, adhere to each other during mixing, and are difficult to achieve uniform dispersion, resulting in uneven fertilizer quality and affecting the fertilization effect. When dealing with large doses of biological organic fertilizers and functional bacteria, conventional devices have limited stirring strength and methods, and cannot ensure their full mixing, easily resulting in large local concentration differences, reducing the fertilizer efficiency stability. Moreover, various impurities such as plant residues and soil clods are often mixed in the raw materials of biological organic fertilizers. These impurities not only interfere with the normal growth and reproduction of functional bacteria but may also damage the normal operation of the equipment during the mixing process, increasing the equipment maintenance cost and failure rate. Traditional devices lack targeted pretreatment, efficient mixing, and impurity treatment mechanisms, and are difficult to meet the requirements of high-quality production of modern liquid biological organic fertilizers. There is an urgent need for a new type of functional bacteria uniform adding device to solve these problems. Summary of the Invention

[0047] Please refer to the appendix Figure 2 , specifically, a level gauge II 40 is provided at the top of the main mixing tank 2 to detect the material capacity in the main mixing tank 2.

[0048] Working principle: In the production process of liquid bio-organic fertilizer, first, the bio-organic fertilizer raw materials and functional bacteria enter the impurity removal tank 11 and the impurity removal tank 12 respectively. Under the influence of their own gravity, the bio-organic fertilizer raw materials and functional bacteria flow down from the top of the impurity removal tank 11 and the impurity removal tank 12. During the movement of the bio-organic fertilizer raw materials and functional bacteria, the multi-layer filter screens 15 on the inner walls of the impurity removal tank 11 and the impurity removal tank 12 filter out the impurities and lumps in the bio-organic fertilizer raw materials and functional bacteria, and the mesh number of the filter screen 15 gradually increases along the material flow direction, intercepting the impurities in the bio-organic fertilizer layer by layer (the mesh number of the filter screen 15 generally gradually expands from 10 - 20 meshes to 100 - 200 meshes. The 10 - 20 mesh filter screen 15 is mainly used to intercept larger particles of impurities, such as plant fiber fragments and larger soil clods in the organic fertilizer; the 100 - 200 mesh filter screen 15 can intercept tiny impurities, such as mineral particles and microbial flocs suspended in the liquid. The specific mesh number is determined by the type of bio-organic fertilizer actually used), avoiding the poisoning effect of impurities in the bio-organic fertilizer on the functional bacteria. On the other hand, the motor 13 on the outer wall of the impurity removal tank 11 and the impurity removal tank 12 is started to rotate the rotating rod 14, driving the filter screen 15 installed on the rotating rod 14 to rotate, realizing the shaking off of the impurities accumulated on the filter screen 15.

[0049] After the impurity-removed biological organic fertilizer raw materials and functional bacteria enter the secondary mixing tank 3, the first stirring paddle 7 rotates continuously and steadily driven by the motor, preliminarily stirring and mixing the materials to make the material distribution more uniform. At this time, the heating mechanism operates synchronously, and the heat preservation jacket 18 tightly wraps the secondary mixing tank 3. The electric heating belt 19 inside it, under the coordinated action of the first temperature sensor 21 (the sensor can be a PT100 or K-type thermocouple temperature sensor) and the PCB controller 21 (the controller can be an XMTD-2202 temperature controller or an OMRON E5CN-Q2HBT temperature controller), maintains a suitable pre-treatment temperature environment (each functional bacterium has its optimal growth temperature range. For example, Bacillus is a commonly used functional bacterium in biological organic fertilizers. The optimal growth temperature of Bacillus subtilis, for instance, is generally between 25-37°C. Within this temperature range, the enzyme activity in the functional bacterium is in the best state, and the metabolic activities are vigorous; when the temperature exceeds the appropriate range, the activity of the functional bacterium will be inhibited or even damaged. If the temperature is too high, such as exceeding 45°C, biological macromolecules such as proteins and enzymes in the functional bacterium will denature. The spatial structure of the protein will be destroyed, resulting in the loss of its function, and the enzyme will also lose its catalytic function due to the change in the structure of the active center). As a catalyst in living organisms, enzymes can efficiently participate in various biochemical reactions at suitable temperatures, such as the absorption, decomposition, and utilization of nutrients, as well as the processes of cell division and reproduction. When the liquid biological organic fertilizer and functional bacteria are mixed at a suitable temperature, the functional bacteria can quickly adapt to the new environment and use the nutrients in the fertilizer for growth and reproduction. This not only helps the functional bacteria to be evenly distributed in the fertilizer but also ensures that they can exert better fertilizer efficiency in the subsequent use process; after reaching the appropriate temperature, the first temperature sensor continuously monitors the temperature inside the secondary mixing tank 3 and quickly feeds back the data to the PCB controller 21. If the temperature deviates from the set value, the PCB controller 21 immediately adjusts the heating power of the electric heating belt 19 to ensure temperature stability. On the other hand, when the temperature rises, the viscosity of the biological organic fertilizer will decrease, making the mixing degree with the functional bacteria more uniform (temperature has a significant impact on the viscosity of liquid biological organic fertilizers. Generally speaking, as the temperature rises, the viscosity of the liquid decreases. Liquid biological organic fertilizers contain various organic and inorganic components, such as polysaccharides, proteins, minerals, etc. The presence of these components makes the fertilizer have a higher viscosity at low temperatures. For example, some biological organic fertilizers containing more polysaccharide substances are viscous at low temperatures because the interaction between the polysaccharide molecular chains is enhanced. When the temperature rises, the thermal motion of the molecules intensifies, the force between the molecular chains weakens, and the fluidity of the liquid increases. This change is beneficial to the diffusion and uniform mixing of functional bacteria in the liquid because the lower viscosity makes it easier for functional bacteria to move in the fertilizer and reduces the resistance to mixing).After the biological organic fertilizer and functional bacteria reach a certain degree of mixing (the degree of mixing is determined by sampling and testing. Generally, when there is no obvious layering phenomenon in the sample (for example, for the pre-mixing of some functional bacteria containing Bacillus and liquid organic fertilizer, if there is no white bacterial film formed on the liquid surface and no obvious precipitation at the bottom, it indicates that the functional bacteria are relatively evenly distributed in the liquid, and it can be considered to enter the main mixing container), they can enter the main mixing tank 2). The first liquid pump 8 transports the treated material in the secondary mixing tank 3 to the main mixing tank 2 through the first feed pipe 9 for further treatment.

[0050] When the material arrives at the main mixing tank 2, the second motor 22 drives the rotating shaft 23 to rotate at a high speed. The stirring paddle two 24 on the rotating shaft 23 stirs the material. The sliding groove inside the stirring paddle two 24 provides a moving space for the telescopic assembly. When the stirring paddle two 24 rotates, the telescopic assembly is thrown out by its centrifugal force until the fitting plate 32 contacts the inner wall of the main mixing tank 2. When the viscosity of the material in the tank is too high, the third motor 29 starts, driving the first gear 30 to rotate. The adjacent first gears 30 cooperate with each other through the transmission gear 34, causing the rotating rod 31 to rotate accordingly, driving the stirring block 33 on the rotating rod 31 to rotate. The rotating block is elliptical and can cut the material to achieve the effect of breaking the adhesion of the material and improving the mixing degree of the material. On the other hand, the inside of the rotating shaft 23 is hollow and is connected to the first impurity removal tank 11 through the adding pipe 26, and functional bacteria can be continuously added during mixing. Moreover, the connection between the nozzle 27 and the outer wall of the rotating shaft 23 is spherical. When the stirring paddle two 24 rotates, the nozzle 27 is impacted by the material to form a phenomenon where the spraying direction is opposite to the material flow, further improving the mixing degree of the functional bacteria. At the same time, the heat preservation sleeve 18, the electric heating belt 19, the second temperature sensor 36, and the second PCB controller 37 of the main mixing tank 2 also cooperate closely to maintain a stable reaction temperature. The second temperature sensor 36 monitors the temperature inside the main mixing tank 2 in real time. Once the temperature fluctuates, the second PCB controller 37 quickly adjusts the heating power of the electric heating belt 19 to ensure that the biological organic fertilizer and functional bacteria are fully and evenly mixed in the optimal temperature environment without being interfered by the change of the external environmental temperature.

[0051] The first liquid level gauge 10 and the second liquid level gauge 40 respectively monitor the liquid levels in the secondary mixing tank 3 and the main mixing tank 2 accurately and in real time to ensure that the material quantity is always within a reasonable range, avoiding affecting the mixing effect and equipment operation due to too much or too little material. Moreover, the setting of multiple secondary mixing tanks 3 can realize the parallel processing of materials, improving the production efficiency. The equipped maintenance ladder 38 on the outer wall of the main mixing tank 2 facilitates the daily maintenance and repair work of the equipment. The operator can safely and conveniently check and repair the equipment through the maintenance ladder 38. The design of the observation port 39 facilitates the operator to view the mixing situation in the main mixing tank 2 in real time, discover problems in time and make adjustments to ensure the efficient, stable and orderly progress of the entire production process.
